Abstract: A gas cylinder of the present invention comprises a housing having a tube, a front head and an rear end cap defining a chamber. A pair of ports are provided to allow for the input and exhaust of gas in the chamber. A piston is received in the chamber for axial movement within the chamber and separates the chamber into two cavities. A rod is operatively connected to the piston and extends forwardly from the piston, through a bore in the front head to exit the chamber through the front head. The rod is loosely or floatingly connected to the piston, to be movable relative the piston by a plate at an end of the rod which is trapped in a bore in a forward end of the piston. A piston seal is received in a groove in the piston to form a seal between the piston and the cylinder tube. The piston is flexible and changes shape due to pressure changes within the chamber. A rod seal is also provided between the rod and the front head bore.

Abstract: A disconnectable golf club, comprising an upper section, and a lower section, which are secured together by means of a connector, one comprising a female part, the other a male part, and which includes one or more detents, and detent seats, that are constantly biased into engagement, to afford an interconnection of the golf club together, when assembled, but allows for prompt and remote disconnection, through the depression of a the detent or a control rod connected to the detent, when the golf club sections are to be separated, or a different club head is to be installed for usage and application for driving or putting of a golf ball.

Abstract: A recoil pad assembly (10) fitted to the stock of a weapon (W) such as a rifle or shotgun for cushioning a shooter (M) against recoil forces produced when the weapon is discharged. A first pad member (12) is installed on a butt end (E) of the stock (T) of the weapon. A second pad member (14) is pressed against a shoulder (S) of the shooter when the shooter prepares to discharge the weapon. The second pad member interfits with the first pad member for movement of the pad members relative to each other when the weapon is discharged. Compression springs (56) then restore the pad members to their original position relative to each other. A seal is effected between the pad members when the weapon is discharged trapping air between the members. Relative movement of the pad members then compresses the air producing a cushioning effect which lessens the recoil force to which the shooter is subjected.

Abstract: A choke assembly (10) is attachable to the muzzle end of a shotgun barrel (G) to produce a tightened shot pattern when the shotgun is fired. A shotgun shell includes shot (S) and a wading (W). The wading is spun through the barrel by discharge gases created when the shell is fired, and this spinning motion tends to increase the size of the shot pattern. The choke comprises an elongate hollow tube (12) having an inner end (14) receivable in the muzzle end (M) of the barrel. An inner diameter (D1) of the tube corresponds to that of the barrel at its muzzle end. An outer end (24) of the tube extends beyond the muzzle. The inner diameter of the tube decreases from the inner to the outer end of the tube to effect a choke. The outer end of the tube also has a plurality of longitudinally extending slots (28) formed therein, these being spaced circumferentially about the tube. Discharge gases propelling the wading through the barrel tends to force the wading radially outwardly through the slots.

Abstract: This actuator switch assembly is used in conjunction with a concrete block machine and provides first and second switch portions, each attached to one of the height pins of the concrete block machine. Both switch portions include spring-loaded plungers and one of the portions includes a pair of electrical contacts which are closed by engagement of the plungers when the height bars approach each other.

Abstract: This core puller assembly includes a bank of interconnected core puller units each having a cylinder, and a piston mounted within the cylinder and having a rearwardly extending connecting rod. Each core puller unit includes a core puller bar disposed in side-by-side relation below the cylinder and connected to the piston connecting rod for movement with said connecting rod. Each cylinder carries front and rear guide units receiving the core puller bar in sliding relation to guide the core puller bars into the mold assembly.The cylinders are operated by a pneumatic air supply which includes a surge tank and a control system for controlling the supply of pressurized air to the cylinders.

Abstract: This fluid operated clock comprises a support stand which includes a shaft providing a pivot mounting for an oscillating housing, and which carries a reservoir above the housing for supplying fluid to housing inlet openings. The housing is partitioned to provide outer fluid compartments, having fluid discharge openings, and an intermediate compartment mounting an adjustable balance weight above the pivot center. The housing oscillates between defined limits and includes an actuating pin engageable with a pawl and ratchet assembly to rotate a wheel carried by the shaft and having an indicator ring attached.
