Abstract: A multi-blade ice-skate footwear includes a foot-retaining section with a substantially planar bottom surface, a first blade adjustably connected to an anterior portion of the bottom surface, and second and third blades adjustably connected to a posterior portion of the bottom surface and spaced from the first blade respectively. The ice-skate footwear includes a mechanism for selectively biasing the first blade along a first reciprocating linear path while simultaneously biasing the second and third blades along second and third reciprocating linear paths respectively.

Abstract: A patient hoist having a base, a load sensor mounted to the base and a mast assembly including an elevation arm and a body support member extending from the load sensor. The patient hoist is used to determine a patient's weight while the patient is assisted to a standing position or suspended.

Abstract: A threaded cylinder frame ending at a flange ring and extending in a semicylindrical half sleeve for attachment to another semicylindrical half sleeve. A Locknut with barbs secures and grounds the cylinder frame to the service box wall, and a janus flange ring prevents the connector from passing through the box wall and the pipe from passing through the connector to the box wiring. The length of the half sleeves accommodate random environment movement and retain the pipe within the conduit system. The removable half sleeve allows the pipe to be laid on the catchment area of the main half sleeve and a portal to be formed between the end of the pipe and the flange ring, permitting inspection and repair of wiring.

Abstract: An improved mortise lock is provided with spring means for independently returning each of the inside and outside lever handles from a rotated operating position. Inside and outside operating hubs are independently rotatably mounted in the case. A retraction lever extends from a pivot past the hubs and into retracting engagement with the tailpiece of the latch bolt. Rotation of one of the operating hubs causes a cam flange thereon to engage the retraction lever to pivot the retraction lever rearward to retract the latch bolt. In one embodiment, a complementary pair of inside and outside hub bias arms are pivotally mounted in the case in side-by-side relation. Each bias arm is biased against its companion hub to return the hub from a rotated lock-operating position. In another embodiment, a single hub bias arm is biased against either the inside or the outside hub.
