Patent DE-3482672-D1 (DE)
Inventor: LIM FRANKLIN
IPC: A61K9/52
Filed: 1984-04-06
Granted: 1990-08-16
Abstract: A dispensing system for the sustained releasing of a substance at a substantially constant rate includes semipermeable capsules containing a material to be released. The capsules comprise membranes having pores of dimensions sufficient to control the kinetics of release provided there is maintained a large intracapsular concentration of the substance relative to the concentration desired in the extracapsular environment. The system may be produced by forming permeable capsules, suspending the capsules in a solution containing a high concentration of the substance to load the intracapsular volume, and then post-treating the capsules to reduce the size of the pores.

Abstract: A process and apparatus for continuously forming a product having elongate members (10) at least about one foot long which are oriented, compressed and bonded. The process comprises depositing elongate members (10) on a moving carrier (39) with an orientation that is substantially parallel to the direction of movement of said carrier (39), said members (14) being deposited on said carrier (39) over a length of carrier (39) that is at least as long as about one-half times the length of the elongate members (10) and is at least as long as about 30 times the final thickness of the compressed, composite product. The apparatus comprises a first conveyor (30) along which elongate members (10) travel, said elongate members (10) being arranged transverse to the direction of travel of said first conveyor (30). This first conveyor (30) feeds a second conveyor (33) which is arranged to move transversely of said first conveyor (30) and to collect said elongate members (10). The second conveyor (33) then feeds a third conveyor (39) whereupon the final product is formed.

Title: Improvements relating to retractors
Inventor: SHARPE DAVID THOMAS
IPC: A61B17/02
Filed: 1985-03-07
Granted: 1989-06-15
Abstract: The invention defines a plastics disposable, hand applied medical retractor for retracting flesh at the edges of an incision or aperture in the human or animal body. At one end the retractor has a sharply inturned hook portion on the end of which are short, sharp, triangular teeth for impaling the flesh. The retractor bows upwardly from the hook portion and back down to a pad which has an adhesive undersurface so that it can be pressed directly to the skin so as to anchor thereto to keep the pulled back flesh in the retracted position. The said bowing allows the pulled back flesh to bunch upwardly to prevent such flesh from forcing the teeth out of engagement with the flesh and also provides inherent springiness tension in the retractor when it is applied improving its performance. Instead of the pad having adhesive it may have one part touch and close fastener, the other part being previously applied to the skin by pressure sensitive adhesive.

Abstract: A lock assembly for cabinet doors comprising a mounting plate attachable to the door panel and provided with a depression in its front face to receive a handle. The handle is connected to an operating shaft for a lock adjusting member in a spring loaded manner to cause the handle to be ejected from the depression pivoting about an axis perpendicular to the axis of rotation of the adjusting member. The hand lever is retained in and released from the depression by means of the lock assembly. The lock is installed in the mounting plate separate from the depression with the handle therein, and penetrates the door panel through an opening. The lock controls a slide adjustably disposed in the mounting plate by means of a detent element engaged in the depression, the detent element retaining the handle in the depression when the lock is in the locking position and releasing the handle which is ejected from the depression when the lock is in the unlocked position. This invention provides a lock assembly which has a small structural height, can easily be sealed, and has a conveniently and comfortably grippable handle.

Abstract: Ballast and starting circuits for controlling current and voltage applied to an electrical dishcarge lamp. The ballast circuits use positive and negative capacitors which are alternately charged and discharged in an asychronous manner. The positively charged capacitors are charged during positive portions of alternating current and discharged during negative portions of the alternating current. The negatively charged capacitors are charged during negative portions of the alternating current and discharged during positive portions. Transistors or other appropriate switching means are used to switch the capacitors to the lamp during discharge thereof. Startup circuits are included for boosting the voltage applied to the lamp either manually or automatically upon startup. A startup regulator circuit is also shown for controlling current flow during periods of high current demand such as during startup.
