Abstract: An assembly (15) of a tool (16) and straight edge (27), with a cutting edge (38) extending beyond a member (17) of tool (16) which lies along straight edge (27). The member including cutting edge (38) is supported by member (17) and cuts excess wet cement from a supporting base (22) to form a surface with the cement. A T-bar (37) having a leg (39) is included in the member having cutting edge (38). Edge (38) removes a web 20 of excess fluent material as member (17) slides upwardly along straight edge (27). A distal end (55) of T-bar (37) removes a web (56) of excess material from an interior supporting base (22) in another application. A member (24) adjusts the cutting length of edge (38), being mounted along an edge (19) of tool (16), while a flange (27f) is included in straight edge (27 ) for providing a guide by which member (17) and cutting edge 38 shift uniformly upwardly to remove excess 20 of fluent material.

Abstract: An optical device for aligning an instrument so that active zones in the instrument are the same distance from the plane of a remote object comprising a lens attached to the instrument, the lens having a curved outer surface and a mirrored back surface. When the active zones in the instrument are aligned parallel to the plane of the remote object and the remote object is illuminated, the proper alignment is indicated by light emanating from the object being focused on a preselected spot.

Abstract: A process for improving the efficiency of heat transfer to a flowing fluid in a tubular heat exchanger by placing an injector on the inlet of each heat exchanger tube, the injector designed to create tangential flow in the tube. The injector used to generate tangential flow comprises a tubular cap with multiple passageways therethrough so that fluid entering the passageways enters the heat exchanger tube along a line tangent to the circumference of the hole extending along the length of the heat exchanger tube. A significant increase in heat transfer at the same pumping power is obtained as a result of the cross sectional shape of the passageway and the dimensions thereof in relationship to the inner diameter of the heat exchanger tube.

Abstract: The present invention relates to a method for treating and disposing of materials contaminated with blood such as blood soaked menstrual pads or tampons. The invention further relates to a system for decontaminating and disposing of blood soaked products comprising a bag containing a disinfecting material, the bag having a readily openable portion for placing the blood soaked product into the bag and in contact with the disinfecting material and then resealing the bag to prevent its contents from contaminating the surroundings. Once resealed, the seal can not be removed without destroying the seal.

Abstract: A bathenette seat for bathing a baby is provided where the seat has a headrest with an opening which is sized and shaped to accept the back of the head of the baby being bathed so as to allow the washing of the back of the baby's head without allowing soap to get into the baby's eyes or ears. The bathenette further includes a leg support spaced from the headrest and a sprayer located on the leg support. The sprayer is positioned to spray water on the baby reclining in the seat. The bathenette also includes a height adjustment mechanism to vary the position of the headrest and a band around the opening of the headrest to further support the baby's head.

Abstract: An automatic centrifuge, especially useful with the Censlide.TM. containers, enables automatic operation in the centrifuging of samples. The centrifugal speed is ramped up to a first speed for about 45 seconds, the first speed maintained for about 15 seconds, the speed is then ramped down to a second speed during a 15 second time interval, and the second speed maintained while the samples are flicked a predetermined number of times. The centrifugal speed is then ramped down to zero. The automatic operation, and flicking enables the samples to be examined in their containers as soon as the automated cycle, requiring a time period of from one and one half minutes to about two minutes, is ended.

Abstract: A device for delivering an erection causing stimulus to the penis comprising a ring for placement of the penis. In one variation of the device the ring includes a needle guide projecting from the surface of the ring. In a second variation the ring includes a porous drug delivery media attached to the inner surface of the ring. In a third variation the ring has an electrically conductive material attached to the inner surface of the ring.

Abstract: A woodworking machine comprising one or more sets of parallel rotating blades position in or above a flat worktable surface such that multiple sets of parallel grooves of a controlled depth can be cut into a wood block moved over the table surface and above, below or between the rotating blades. The product produced by the machine is of a unitary construction comprised of multiple wedge shaped shims held together by a breakable membrane between the shims.

Abstract: A work station for mounting to the side of a vehicle to aid a mechainc in reaching the engine compartment comprising a platform surface, four legs movably attached to the platform so that the height of the platform is adjustable, a brace attached to the platform to space the platform away from the side of the vehicle, and mounting means for attaching the platform to the side of the vehicle so that the platform does not move during use.

Abstract: Disclosed is a coil stent constructed from a nitinol alloy having the ends thereof shaped to interact with a placement device specifically designed to hold the stent in a reduced diameter while it is being maniuplated to its desired position in the patient's body. The placement device is a hollow tube which has holes in it surface allowing placement of the ends of the stent therethrough so that they can be held in place inside the interior of the placement device by a mandril which is threaded through the center of the placement device. The combination of the features of the shapes on the end of the stent, the holes in the placement device and the mandril which passes through the placement device and the shapes on the end of the stent allow the interventional radiologist to accurately and rapidly place the stent in its desired position before it changes shape to its final pre-set configuration.

Abstract: A hanger for holding a chemical dispenser within the tank of a toilet bowl comprises a bracket adjustable in length, a dispenser holder, hooks for mounting the hanger during both use and exchange of the dispenser, and a lifting mechanism to allow the hanger to be raised without soiling or wetting the user's hands.

Abstract: The invention comprises a system for the long term continuous delivery of medication to hollow body organs. It is particularly suited for the deivery of chemotherapy drugs to lesions in the walls of those organs. The invention, specially designed for the treatment of the prostate gland, comprises a urinary drainage catheter which has an additional lumen within the wall thereof, said lumen proximate end connected to a space external of the catheter wall enclosed by a porous membrane. The distal end of the lumen, which is external to the penis when the catheter is positioned in the body, has a valved end for introduction of liquid medication therethrough. In use, the catheter is placed within the urethra, with the porous membrane portion adjacent the prostatic ducts. Medication introduced through said valve is transmitted along the lumen into the space between the catheter and the porous membrane, through the membrane and into contact with the prostatic ducts.

Abstract: Disclosed is a method for forming a denture in-situ in the mouth of a dental patient. The method starts with a try-in of the teeth in wax formed to duplicate in shape the desired form of the finished denture. An in-situ impression of the try-in in alginate is followed by placing of the teeth in the resultant impressions in the alginate and subsequent acrylic buildup and in-situ forming and setting of the final acrylic denture.
