IPC: B01L3/00
Filed: 1991-08-09
Abstract: PATENT     CALIBRATION CUVETTE                 ABSTRACT OF THE DISCLOSURE     The calibration cuvette apparatus for storing and calibrating a chemical sensor in a tonometered solution includes an upper cuvette section and a lower cylindrical valve section for alternately sealing the cuvette section and admitting a gas mixture to the cuvette section.  The upper cuvette section has relatively narrow diameter upper and lower ends on either side of a wide diameter middle  portion.

Structure associated with the cavity and exposed at an outer surface of heel expels liquid from the cavity when the heel is pressed down and aspirates liquid in contract with the outer surface when the heel is lifted.  An elastically compressible sponge body fills the cavity.  This cavity can be a pocket open at the outer surface of the heel or it can be offset from the surface of the heel in which case at least one passage extends between the cavity and the heel outer surface.  The cavity can also be empty and offset form the surface of the heel with at least one passage extending between the cavity and the heel outer surface.

Filed: 1991-12-17
Abstract: CASTING APPARATUS     Abstract Of The Disclosure Casting apparatus comprises a vacuum box having a pair of laterally spaced side walls sealingly engaged to a pair of pick-up members disposed along laterally spaced apart sides of a casting mold.  The vacuum box also comprises a pair of spaced end walls sealingly engaged to the casting mold.  Sealing engagement of the laterally spaced vacuum box side walls to the pick-up members, rather than to the mold, permits a substantial reduction in the lateral dimension of the mold, thereby substantially reducing the amount of costly mold material (e.g., resin-bonded sand) needed to fabricate the mold for casting and to be disposed of after casting.

Abstract: TITLE OF THE INVENTION           METHODS AND APPARATUS FOR FORMING FEATURES ON AN ELONGATED METAL WIRE                 ABSTRACT OF THE DISCLOSURE         The present invention relates to methods and apparatus for forming features on an elongated metal wire and, in particular to making features, such as pin tips, compliant sections and retention sections on electrical terminal pins for use in interconnecting electrical leads, plated through holes in printed circuit boards and/or connector contacts.
Patent CA-2067638-A1 (CA)
Title: Pressure devices
Inventor: CASSIDY RONALD F
IPC: H01H35/38
Filed: 1992-04-30
Abstract: ABSTRACT OF THE DISCLOSURE     A pressure indication device comprises a housing including a bore in which is received a slidable piston.  The piston has two end faces,  one of which is for connection to a source of fluid at higher pressure and the other of which is for connection to a source of fluid at lower pressure.          The  device  produces  an  indication  when  the  pressure differential  reaches  a  predetermined  value.     In  an inoperative  position  of  the  piston,  a  portion  of  the upstream face co-operates with the bore to provide a face seal which reduces leakage between the bore and the piston and which also reduces the effective area of the upstream face.  In addition, a labyrinth seal is provided between the bore and the piston.  When the predetermined pressure is  reached,  the piston moves,  and  as  it  does  so,  the effective area of the upstream face is increased.   This causes  increasingly  rapid  movement  of  the  piston  so providing  a very positive  indication that  predetermined pressure has been reached and so overcoming any tendency of the piston to stick or move only very gradually as the predetermined pressure is reached.

Title: Low-calorie drink and process and apparatus for production thereof
Inventor: GRESCH WALTER
IPC: A23L2/70
Filed: 1991-08-14
Abstract: The reduced-calorie beverage of the invention is made of sweet fruit juices of vegetable products, especially grapes, berries and other fruits. The raw juice is first selectively de-sugared by the physical removal of sugar in contact with the fruit juice, whereupon enough water is added and/or removed so that the water content again approximates to that of the original fruit juice. In the ideal case, enough low-calorie sweetener is then added to the de-sugared juice to give the same degree of sweetness as at the outset. The pre-separation process removes various components from the raw juice before de-sugaring which are replaced thereafter.  This gives a reduced-calorie beverage which has much the same flavour, sweetness, components and colour as the natural fruit juice.
