Title: Hydraulic platform lift for truck trailers
Inventor: GRAY RALPH EDWARD
IPC: B60P1/44
Filed: 1990-01-09
Granted: 1995-09-19
Abstract: A hydraulic platform lift for use on trucks and truck trailers has two hydraulic cylinders, one on each side of a door.  The cylinders are phasing cylinders in that one cylinder is larger than the other cylinder by a specific ratio.  The cross-sectional area of the fluid in the rod end of the larger cylinder minus the area of the rod is equal to the cross-sectional area of the smaller cylinder.  A connecting line interconnects the rod end of the large cylinder with the cap end of the small cylinder. Hydraulic fluid can be directed by control means into the cap end of the large cylinder or the rod end of the small cylinder.  For upward movement, hydraulic fluid is forced into the rod end of the small cylinder.  This in turn forces hydraulic fluid through the connecting line into the rod end of the large cylinder, thereby raising both pistons.  For downward movement, hydraulic fluid is forced into the cap end of the large cylinder, thereby forcing fluid out of the rod end of the large cylinder and into the cap end of the small cylinder.  This causes both cylinders to move downward.  The platform lift also has a self-levelling feature whereby the pistons can be made level with one another by moving the platform into an uppermost position.  The operational mechanism is located entirely at the sides of the trailer.  The lift platform can be made to exert a positive upward force or a positive downward force during use.

Title: Syringe with protective housing
Inventor: HOLLISTER WILLIAM H
IPC: A61M5/31
Filed: 1992-09-08
Granted: 2004-03-30
Abstract: To provide a high degree of protection against the possibility of someone being accidentally punctured by a contaminated needle, the syringe of the present invention has directly connected thereto a protective housing, which can be pivoted to a position in alignment with the contaminated needle to envelop the same. As the housing is pivoted into the alignment position, locking mechanisms integral of the housing would fixedly retain the needle within the housing. The syringe of the present invention may be modified to include a housing containing an integral collapsible section and a sealer adapted to the distal portion of the housing such that, upon collapse of the collapsible section of the housing, the tip of the contaminated needle would penetrate into and be sealingly secured by the sealer. Another modification of the syringe of the present invention involves utilizing a collapsible hinge to connect the protective housing to the main body portion of the syringe. Upon collapse of the collapsible hinge, the longitudinal distance separating the housing from the main body of the syringe is reduced, thereby causing the tip of the contaminated needle to pierce and penetrate into the sealer and be sealingly retained thereby.
