A magazine grip attachment for ammunition magazines to aid in extraction of a magazine from ammunition pouches comprising a sleeve of resilient material molded in the general shape of a magazine yet with a smaller inner circumference than the circumference of a magazine so as to require the band to stretch over the magazine. The top of the band has an even slightly smaller inner circumference than the lower part of the band. Extending from the top of the band is a handle designed to allow a finger to wrap around the handle and extract the magazine. Also provided are recessed areas and four diagonal force distribution beams to constrict the invention and allow it to grip a magazine more snugly when the handle is pulled. The invention is also used in combination with a magazine pouch to deaden noise by biasing the magazines against the pouch and each other.

In a fluid cylinder assembly, comprising, an operating fluid cylinder having a cylinder housing, an elongate piston rod reciprocal in said cylinder housing and a spring abutment collar adjacent a first end from which projects said piston rod, a spring housing into which is housed said operating fluid cylinder, said spring housing being open at opposite ends while simultaneously providing a spring abutment at a second end remote from a third end thereof whereat said piston rod projects from said spring housing, a stop encircling said cylinder housing adjacent said first end thereof and being secured to said spring housing adjacent said third end thereof, a spring oriented in a compressed state between and engaging said spring abutment collar and said spring abutment to continually urge said cylinder housing and said spring abutment collar thereon toward said stop, said cylinder housing having at least one fluid connection at a fourth end remote from said first end, wherein the improvement comprises in combination: (a) said fluid connection is defined by a first internally threaded opening in said hydraulic cylinder; (b) a service kit comprising a first coupling member having a first external thread threadedly coupled to the thread of said first internally threaded opening and having an axially extending bore therethrough with at least a portion of said bore having a second internal thread configured to provide a connection to a fluid system; (c) a second coupling member having a second external thread and an enlarged head at one end thereof, said second external thread being configured identically to said first external thread; and (d) a plate-like member having a guide hole therethrough configured to loosely receive therethrough said second external thread and prevent said enlarged head from passing therethrough. 3. A service kit for facilitating access to a fluid cylinder assembly, comprising, an operating fluid cylinder having a cylinder housing, an elongate piston rod reciprocal in said cylinder housing and a spring abutment collar adjacent a first end from which projects said piston rod, a spring housing into which is housed said operating fluid cylinder, said spring housing being open at opposite ends while simultaneously providing a spring abutment at a second end remote from a third end thereof whereat said piston rod projects from said spring housing, a stop encircling said housing adjacent said first end thereof and being secured to said spring housing adjacent said third end thereof, a spring oriented in a compressed state between and engaging said spring abutment collar and said spring abutment to continually urge said cylinder housing and s aid spring abutment collar thereon toward said stop, said cylinder housing having at least one fluid connection at a fourth end remote from said first end, said fluid connection including an opening in said hydraulic cylinder, said opening having a first internal thread, said service kit comprising: a coupling member having a first external thread and an enlarged head at one end thereof, said first external thread being configured to threadedly coupled to said first internal thread; and a plate-like member having a hole therethrough configured to loosely receive therethrough said second external thread and prevent said enlarged head from passing therethrough. 4. The service kit according to claim 3, wherein said fluid connection includes a fluid coupling member having a second external thread configured to couple to said first internal thread, said fluid coupling member having an axially extending bore therethrough with at least a portion of said bore having a second internal thread configured to provide a connection to a fluid system. 5. The service kit according to claim 4, wherein said plate-like member is of a size larger than the cross Section of said spring housing. 6. The service kit according to claim 4, wherein a length of said coupling member is greater then the length that said spring is operatively compressed between said spring abutment collar and said spring abutment with no load applied to said piston rod. 7. A method for accessing a hydraulic cylinder in a fluid cylinder assembly, comprising, an operating fluid cylinder having a cylinder housing, an elongate piston rod reciprocal in said cylinder housing and a spring abutment collar adjacent a first end from which projects said piston rod, a spring housing into which is housed said operating fluid cylinder, said spring housing being open at opposite ends while simultaneously providing a spring abutment at a second end remote from a third end thereof whereat said piston rod projects from said spring housing, a stop encircling said cylinder housing adjacent said first end thereof and being secured to said spring housing adjacent said third end thereof, a spring oriented in a compressed state between and engaging said spring abutment collar and said spring abutment to continually urge said cylinder housing and said spring abutment collar thereon toward said stop, said cylinder housing having at least one fluid connection at a fourth end remote from said first end, said fluid connection including an opening in said hydraulic cylinder, said opening having a first internal thread, comprising the steps of: placing a coupling member having a first external thread and an enlarged head at one end thereof through a hole in plate-like member and effecting a threaded coupling of said first external thread with said first internal thread, orienting said plate-like member against said spring housing and drawing by operation of said coupling member in a first direction of rotation said hydraulic cylinder toward said plate-like member to further compress said spring and draw said spring abutment collar away from said stop, unsecuring and removing said stop from said spring housing, operating said coupling member in a second direction of rotation to effect movement of said hydraulic cylinder away from said plate-like member to reduce the compression of said spring entirely to facilitate removal of said hydraulic cylinder from said spring housing after disengagement of said first external thread from said first internal thread. 8. The method according to claim 7, wherein said coupling member has a length greater than the length that said spring is operatively compressed between said spring abutment collar and said spring abutment with no load applied to said piston rod. um-tight housing and is heated there to a final temperature value (Tfin) by means of warmed oil and by means of a current (I) carried in the winding. The warmed oil is sprayed in the housing at reduced pressure (p) and with the current (I) switched on. At the same time, water is extracted from the active part. The sprayed oil is collected on the housing bottom, after discharging heat to the active part, and, after rewarming, is sprayed once again in the housing at reduced pressure and with the current switched on. The active part is thus dried particularly quickly and carefully.
