Title: Extraction devices
Inventor: KHACHIN VLADIMIR N
IPC: A61B17/221
Filed: 1991-12-12
Abstract: A device (100) for extracting a member from a relatively inaccessible location comprises a catheter (102) and wires (101) made of a material having a thermomechanical storage mermory characteristic, e.g. a titanium nickelide composition; the wires are passed into the location with a cross-section similar to that of the catheter and are then heated by a power supply (103) to change their shape to engage the member. The wires may define a basket, a single loop, or two or more loops which can hold between them a member to be extracted, e.g. a calculus or a polyp from a hollow organ. The preferred composition of the wires is: Titanium: 53.5-56.8 %; TiNi3, Ti11Ni14, Ti2Ni: 2.0-10.0 %; Nickel: Balance.

Title: Improved process for the production of esters from natural fats
Inventor: STERN ROBERT
IPC: C11C3/04
Filed: 1993-09-24
Abstract: A description is given of an improved process for producing esters from natural fats (vegetable and animal fats) and from low molecular weight alcohols, in which the soaps and the oily compounds entrained in the alkaline phases are recycled by treating them, after acidification and separation, with a fraction of the glycerol phase produced, in the presence of an alkaline catalyst and in order to form at best a triglyceride or a partially substituted glyceride. This process makes it possible quantitatively to obtain methyl, ethyl, propyl or butyl esters which can be used as a substitute for gas oil.

Title: Bathtub-insertable lifting apparatus
Inventor: SCHMIDT PETER
IPC: A61G7/10
Filed: 1994-03-03
Abstract: Abstract The lift platform (16) of a lifting apparatus (10) can be  raised  and  lowered by means  of  an hydraulically operated lifting device (12).

The valves are triggered hydraulically by remote control. For this purpose,  a manual control unit  (30)  with a number of built-in servo valves  is connected to the multi-valve housing  (20)  via  a  flexible  cable  (28), which contains a number of thin control hoses and an hydraulic water supply hose.
Patent CA-2118799-A1 (CA)
Title: A piston diaphragm pump for the delivery of liquids in doses
Inventor: HUNKLINGER HERBERT
IPC: F04B17/04
Filed: 1992-09-03
Abstract: A piston diaphragm pump for delivering doses of liquids, in particular surfactants, wetting agents or the like, has a pump piston movably guided in a pump tube that encloses the pump pressure chamber, and can be electromagnetically driven against the force of a return spring by a magnetic coil that surrounds the pump tube. In addition, a pump diaphragm that is peripherically clamped to the pump housing and faces on one side the pump suction chamber, is rigidly connected on the suction side to the pump piston. A longitudinal bore, within which is arranged a pump piston provided with a piston valve, extends centrally through the pump diaphragm and links the pressure chamber to the suction chamber. In order to obtain the same pump capacity with reduced pump lifts, without the need for providing a specially sealed guidance of the pump piston in the pump tube, the working chamber locted on the side of the pump diaphragm opposite to the suction chamber is designed as an additional pump pressure chamber that is constantly connected to the piston longitudinal bore that leads to the pump tube pressure chamber by cross-channels arranged in the pump piston behind the piston valve.

Title: Heatable milk container
Inventor: FRICKER ROBERT
IPC: A47J27/00
Filed: 1994-05-26
Abstract: A heatable milk container exhibits a heating device (50), which exhibits at least one electrically heatable resistance element (52, 54), which partially envelope in a flat manner the container wall; one or several sensor(s) (56) positioned in the container walls; and a controller (56) that is connected to said sensors for controlled heating of the milk and keeping it warm.  Expediently there are two resistance elements (52, 54), which can be driven independently of each other and of which the one covers the entire container bottom (21'), whereas the other envelope the container shell (21'') over its entire height. The respective resistance element (52, 54) is controlled in such a manner by the controller (55) that the container wall and thus the milk, upon heating, does not exceed an adjustable maximum temperature ranging from 70° to 75°C; and upon reaching a wall tmperature ranging from 60° to 70°C; the heating power is reduced. With this heating device (60) according to the invention, the milk can be, first of all, heated and kept warm with less energy owing to the direct transfer of heat and, secondly, the heating temperature can be accurately controlled in a very simple manner, thus absolutely avoiding overheating of the milk in each heating phase.

Patent CA-2158844-A1 (CA)
Inventor: SCHWARTZ MARK E
IPC: B65B67/08
Filed: 1994-02-14
Abstract: The present invention is a portable manual tape dispens-ing apparatus for use with a stretchable adhesive tape such as of the type that progressively detackifies when stretched. The ap-paratus (10) has a supply spool (14) for carrying a supply of the tape and a handle (12) connected to the supply spool for man-ually grasping and manipulating the apparatus. A mechanism (16) for stretching the tape is arranged and configured to receive the tape from the supply spool. The stretching mechanism has a stretching zone defined between first and second engagement surfaces. The first (32) and second (34) engagement surfaces frictionally engage the tape and move at disparate longitudinal speeds to stretch the tape when the stretching mechanism is activated. A manually operative mechanism is provided for se-lectively activating the stretching mechanism so an operator can remove the tape from the supply in a substantially detackified stretched condition when the stretching mechanism is activated. The manually operative mechanism also permits the operator to remove the tape from the supply in an unstretched condition.
