Abstract: A posterior chamber capsular lens implant and apparatus for implantation of the lens are utilized in a surgical method following a capsulectomy to remove a cataract impaired natural lens. The lens implant has a plane surface and a convex surface. The entire lens is fitted within the capsule of the posterior chamber. Affixed opposite each other within and along the peripheral edge of the lens are a pair of plastic, kidney shaped loops. The method for implanting the lens provides the steps of forming a triangular capsulectomy, extracting the cortical lens matter and any posterior subcapsular plaque matter from the capsular bag, and then inserting the lens implant. The insertion is accomplished by utilizing a plastic sleeve apparatus in conjunction with an irrigating canula. The loops of the lens implant maintain a centralized location of the lens within the posterior chamber capsule thereby eliminating any need for fixating sutures within the eye itself.

Abstract: An under-mattress for bed furniture has an adjustable head part which can be continuously adjusted in its inclined position in both directions, without first having to be returned to its starting position. The horizontal pivoting axis of the head part is chosen such that it divides the head part into two sections, the smaller one of which is nearer the foot of the bed and, as the head part is raised, forms a hollow for the shoulder of a person lying on his side (FIGS. 2 and 13).

Abstract: A box spring assembly which includes a generally rectangular frame, a plurality of upwardly extending wire springs mounted on the frame, and a wire grid supported on the upper ends of the springs so that the grid and springs cooperate to yieldably resist downwardly directed bedding loads. Each of the springs has a body comprised of two side-by-side arcuate portions formed integral at their upper ends with torsion bars that are connected by a connecting bar located between the arcuate portions. The arcuate body portions thus resist bedding loads with bending stresses and without any areas of stress concentration that would cause early spring failure. The torsion bars in each spring divide the spring load and resist bedding loads principally with torsional stresses, the combination of both bending and torsional stresses in the springs enabling increased load-resisting capabilities in the springs with a resulting efficient use of spring wire material.

Abstract: A control valve has a first position in which it directs air under pressure to a wiper motor through a "run" line to actuate the motor to oscillate the wiper. The control valve has a second position in which it directs air through a park line to a valve complex which routes air unidirectionally to the motor to cause the wiper to assume a "park" or rest position. An overriding valve is interposed in the "park" line and is connected to the air pressure source. This valve is of the solenoid type and is intermittently operated by a timer upon its actuation to dispose the overriding valve in a first position in which the flow of "park" air through the override valve is interrupted for a brief period, to allow "run" air pressure to actuate the wiper in normal fashion, and then dispose the valve in a second position in which the "park" air is routed to the motor to temporarily halt the operation of the wiper. This sequence continues so long as the timer remains actuated.
