Radiant heat and steam are applied throughout the chamber and a winding and rewinding operation provides uniform treatment. An inclined chamber section permits gravity feed of the rolls.

Abstract: A clamping device which has a plurality of elongated clamping members joined to a clamp main frame by a pair of slideable side plates which allow the separate clamping members to be moved axially relative to each other and to the clamp main frame so that the clamping members can be adjusted to compensate for irregularities in those workpieces to be clamped that require coaction of two or more clamping members. The slideable side plates are fixed to the clamp main frame and connected to the clamping member by pegs slideable in slots on the clamping member and side plates. A locking nut and bolt clamp the side plates to the clamping member to fix the portion of the clamping member to the frame once the position of the clamping member is determined. The side plates can accommodate relative movement of the clamp support member.

Abstract: A composition which is hydrophobic but possesses excellent wettability comprising a copolymer of a polysiloxane and an ester of glycidyl alcohol and an organic acid. This copolymer is suitable for the manufacture of ocular membranes worn in contact with the eye which present excellent oxygen permeability and which can be worn for extremely long periods of time and then disposed of.A method of preparing the ocular membranes is disclosed, in which the composition is placed between disposable molds and cured therein. The cured, mechanically and optically finished ocular membranes are recovered by the destruction of said molds and without secondary operations.The ocular membrane is a flexible, oxygen-permeable, membrane, adapted to be inserted on the eye and worn thereon continuously for periods of more than one month.

Abstract: A rotary cutter in which a bed knife is displacably mounted with relation to the rotary knife so that the bed knife, when actuated, travels a path between an operative position adjacent the rotary knife and an inoperative position remote from the rotary knife. An extendable linkage connected to the bed knife defines the operative position of the bed knife at the point of maximum linkage extension. Adjusting means connected with the linkage enable precise determination of maximum linkage extension which thereby insures precise setting of the bed knife and prevents bed knife travel beyond the operative position.

Abstract: A method and apparatus for feeding an additive, such as glass fibers, fillers, etc., to a plastic resin in an extruder is disclosed. The additive is fed by means of a screw type feeder into the barrel of a plastics extruder or reciprocating screw plastifier at a location where the resin is molten and the resin pressure is low.

Abstract: A suspension system for a wheel driven, frame mounted motor vehicle including an inner rigid body telescoped into an outer rigid body with the pair of bodies interconnected between the wheel and the frame. A piston in the inner body extends into a piston chamber formed in the outer body. A connecting body having an expansion chamber formed therein is connected to the outer body, and has a deformable envelope disposed in the expansion chamber filled with compressible fluid under pre-determined pressure. Hydraulic fluid fills the piston chamber and the expansion chamber. Valve means are connected to communicate hydraulic fluid between the piston chamber and the expansion chamber responsive to the piston movement whereby the deformable envelope will be compressed.The valve means includes an inlet valve and an outlet valve with a recess formed in the piston chamber axially therebetween to limit and direct the fluid into the inlet valve. Both the inlet valve and the outlet valve are unidirectional.

Abstract: An above ground swimming pool having a rigid retaining wall using interconnecting components which are mainly slotted and notched to form the primary connection and minimally bolted to form the secondary connection.The retaining wall is supported by an improved "A" frame made up of three interfitted members held in assembled position by a tie bolt.The retaining wall has wall sections or sheets slid into opposite facing grooves of two "Z" bars mounted on the wall posts of the retaining wall.A sectional walk deck is snap-fitted to the retaining wall. A picket fence surrounds the walk deck and is connected to a flat plate passing through a slot in the rail post to sandwich the post between adjacent fence sections.

Abstract: An underwater release mechanism for a shackle including a shaft releasably journaled in a casing and held in position by a frangible link to be spring biased to release a shackle hook upon remote actuation causing the link to fracture whereby the shackle is released and the release mechanism floats to the surface. The frangible link externally connected to the casing members to facilitate replacement of the frangible link and reuse of the release mechanism. A rope canister can be attached to the casing with one end of the rope tied to the shackle whereby after release the canister end of the rope will be tied to the float to mark the spot of the shackle. Also a force multiplier can be added to the release mechanism via a second retaining bracket and a second shackle hook to increase the casing load by a ratio of at least 5:1 as for example a release mechanism capable of a 400 pound load would have a 2000 pound load capacity.

Abstract: A liquid feeding system includes a plurality of adjacent liquid feeding chambers having outlets disposed in a laterally aligned integral assembly to supply liquid to a substrate material passing across the outlets. The liquid feeding chambers are divided by vertical partitions into independent units of substantially uniform width and height. A plurality of liquid control means detachably engage the partitions and extend from the chamber outlets to contact the substrate and provide longitudinal passages having selective restricted openings and solidly enclosed sealed boundaries. The liquid control means may be in the form of like sized apertured inserts fitting into the outlets between the partitions and permitting liquid flow only through the selectively dimensioned apertures. Adjacent inserts may include laterally communicating channels between longitudinal passages and overlapping apertures to provide openings of larger widths and varying patterns.

Abstract: A double-action revolver has a hammer assembly which includes a mechanism for positively defining the displacement and the engagement positions of the sear to insure accurate and smooth coaction of the sear with the trigger mechanism.The trigger assembly includes a cylinder-actuating hand, trigger lever, and transfer slide which is raised by the trigger to a position where it is struck by the hammer to percuss the firing pin. Percussing of the firing pin can only be accomplished by coaction of the trigger and hammer, thereby eliminating the requirement for a hammer block or other safety device.The handle of the revolver includes a wedge-shaped section adapted to fit snugly in the web of the palm between the thumb and first finger, while the butt of the handle fits in the hypothenar eminence area of the palm, so that the handle will be stably held at both its upper and lower ends during the firing cycle of the revolver, to prevent bucking or twisting of the revolver when it is discharged.
