Title: Water soluble film
Inventor: VAN PUTTE ANDREW
IPC: B32B27/08
Filed: 1992-05-08
Abstract: A water soluble film suitable for packaging caustic chemicals has an outer layer of a water soluble polymeric material, and an inner layer of a polymeric material which is compatible with the contents of a package made from the film. An intermediate layer can optionally be included to contribute to the tensile strength, bulk, or abuse resis-tance, or some other property of the film.

Title: Refrigerator shelf-like water tank
Inventor: ST-GELAIS GINO
IPC: F25D23/12
Filed: 1992-06-15
Abstract: REFRIGERATOR SHELF-LIKE WATER TANK     ABSTRACT OF THE DISCLOSURE     A refrigerator  in which  one of  the horizontal grill-work shelves is replaced  by a  shallow, flat,  water tank.   The tank is  supported by the same support brackets as the grill-work shelf it replaces.  The tank  bottom wall  includes fore  and aft extending grooves,  for engagement  by the support brackets.  The upturned ledge at the free end of each support bracket  engages a deeper groove  portion at  a front  section of  the main grooves, this groove portion extending short  of  the  front  edge  of the tank.  Thus, only partial forward withdrawal of the tank from the refrigerator chamber  will be  possible in  the horizontal plane, accordingly with  the play  of the  ledge along the deeper groove portion.  This will prevent its accidental fall-out.
Patent CA-2071514-A1 (CA)
Title: Medical valve assembly
Inventor: ROGERS BOBBY E
IPC: A61M39/26
Filed: 1991-04-09
Abstract: A medical valve assembly is described in which the valve assembly has a female luer lock portion (14) on an inlet end of the device and a male luer lock portion (18) on the outlet portion (26) of the valve. A movable piston (8) seals the inlet portion (36) of the valve from the outlet portion when the piston is in the closed position. When a syringe is attached to the inlet portion of the valve assembly, the piston is displaced in a manner that unseals a fluid channel inlet. This connects the end of the syringe to the fluid channel which is connected, at its outlet end, to a catheter or other device connected to a patient. Thus, medication can be introduced to, or fluids aspirated from, a patient's bloodstream without the use of a syringe having a needle.

Filed: 1993-05-14
Abstract: Abstract of the Disclosure A     method and apparatus is described for generating a synchronizing signal for a firing-circuit subassembly to trigger a power converter valve of a controlled series compensator.  According to the invention, a sinusoidal substitute variable is provided, which can be either a measured line current or the sum of a capacitor current and a valve current, such that the zero crossings of said substitute variable do not vary.  This substitute variable is modified in terms of its phase position so that a synchronizing signal that corresponds to the phase position of the capacitor voltage of the series capacitor of the controlled series compensator is made available to the firing-circuit subassembly.  The result, even in the bypassed state, is a sinusoidal synchronizing signal whose zero crossings do not vary, so that operating stability problems no longer occur in the transient state during operation close to resonance.

Title: Fiber optic coupler and amplifier
Inventor: WEIDMAN DAVID L
IPC: G02F1/35
Filed: 1993-11-23
Abstract: Abstract of the Disclosure Disclosed is a fiber amplifier system in which a gain fiber is operatively combined with a fiber optic coupler having first and second coupler optical fibers.  The coupler fibers are fused together along a portion of their lengths to form a wavelength dependent coupling region whereby most of the light power of a wavelength .lambda.s couples between them, and most of the light power of a wavelength .lambda.p that is introduced into the first fiber remains in it. The mode field diameter of the first coupler fiber is substantially matched to that of the gain fiber and is smaller than that of the second coupler fiber.  One end of the first coupler fiber is spliced to the gain fiber.  The difference in mode field diameters between said couplers is sufficient create a difference in coupler fiber propagation constants in the coupling region which degrades the coupling of the .lambda.s signal.  To overcome the difference in coupler fiber propagation constants in the coupling region, and thereby increase the coupled signal power to an acceptable level, a fiber characteristic, whose affect on MFD is insignificant, is modified in one of the coupler fibers.

Title: Method of performing high resolution crossed-array seismic surveys
Inventor: FLENTGE DAVID M
IPC: G01V1/20
Filed: 1994-03-09
Abstract: This invention provides a method for performing three dimensional seismic surveys. In one configuration, receiver lines containing equally spaced receiver stations run in one direction while the source station lines run diagonal to the receiver station lines. The receiver stations and/or the source stations are offset to obtain a desired spatial sampling (number of bins) or multiplicity of the common mid points. In an alternate configuration, the receiver line spacing is offset by a fraction of the source station spacing and/or the source line spacing is offset by a fraction of the receiver station spacing to obtain the desired spatial sampling. These configurations provide higher spatial sampling (smaller bins) compared to the conventional geometries. The smaller bins may be combined to obtain folds (multiplicity) which is sufficient to provide desired seismic imaging while preserving the benefits provided by the higher spatial sampling by the method of the present invention.

Abstract: (Abstract) A viscosity measurement is carried out simultaneously during aspiration of red blood cell component in an blood sample pipetting apparatus.   In a red blood cell pipetting process. a control unit 84 causes a piston 76 to be pulled downwardly so as to produce a predetermined initial aspiration pressure.  A pressure sensor 54 monitors an inner pressure of an air tube 44.  A viscosity measuring unit 86 measures a time required from a point of time when the initial aspiration pressure is produced,  to a point of time when the pressure reaches a predetermined pressure value .beta., and the unit 86 obtains the viscosity of the red blood cell component by comparing the required time with a table 88.  The table 88 stores data corresponding to the relationship between the required time and the viscosity, which is approximately proportional.
