Title: Apparatus for water-cooling oil used in a hydraulic system for actuating an injection molding machine
Inventor: HEHL KARL
IPC: B01D35/18
Filed: 1991-01-22
Granted: 1996-12-03
Abstract: For selectively satisfying a basic cooling demand or a cooling demand which is an integral multiple of said basic cooling demand, the apparatus can be assembled from components selected from a plurality of sets of such components. For satisfying the basic cooling demand the apparatus comprises a single cooler-filter unit. One set of components consists of a plurality of said cooler-filter units. Another set of components consists of mounting blocks, which are to be mounted in a reservoir and adapted to com-municate with cooler-filter units provided on the outside of a wall defining said reservoir. Another set consists of manifold blocks, each of which is adapted to be connected between the port members of cooler-filter units and a mounting block and to which each cooler-filter unit is hydraulically connected by means of a transverse supply passage section and a transverse return passage section. Such an apparatus can be arranged to satisfy a given cooling demand by the provision of one or more cooler-filter units connected to the reservoir and this will not appreciably increase the manufacturing costs.

Abstract: A blood draw needle holder is modified on the outside surface of the closed end and the inside surface of the open end so that the closed end of one holder interlocks with the open end of another holder.   As a result,  one holder with no needle, but   identical   with   another   holder   with   a contaminated needle, may be locked  in place over the contaminated needle.  In addition, a stationery locking  socket  is  provided  for  placement  on  a phlebotomist's  tray  or  cart  for  locking  a  new unused holder in place, with the open end of the unused  holder  facing  upright.   Thereafter,  the phlebotomist  inserts  the  contaminated  needle  end with  its used holder  into the unused holder and locks the two together.  With such an arrangement, no cumbersome telescoping shield is required on the holder being used for taking a blood sample.   A conventional blood draw procedure takes place.  The cost  is  reduced substantially since all holders, whether being used for blood draw or as a shield are  identical  and  made  from  the  same  mold. Moreover,  a plurality of identical holders may be placed in a single container on the phlebotomist's tray for quickly grabbing one for blood draw use or cover use.

Title: Method for signature verification
Inventor: FAN JASON CHIA-SUN
IPC: G06T1/00
Filed: 1992-04-23
Granted: 1996-03-12
Abstract: A method and apparatus are described for verifying handwritten, human signatures, and for permitting access to a system if such a signature is accepted. In an initializing stage, an authorized entrant submits a sample of multiple signatures (110). A first reference signature is selected from the sample (150), and a second reference signature is constructed by averaging over the sample (180). When a subsequent, prospective entrant submits a signature, a dynamic mismatch is calculated with respect to the first reference signature (220), and a shape mismatch is calculated with respect to the second reference signature (240). The signature is accepted if it satisfies a predetermined criterion that refers to the dynamic and shape mismatch values (250, 260).

Title: Downdraft gas range with dual mode burner system
Inventor: BEACH STANLEY H
IPC: F24C15/20
Filed: 1992-11-27
Granted: 1996-11-05
Abstract: A dual mode downdraft gas range provides a number of substantial advantages, including operation in a powered burner mode and an atmospheric mode.  In the powered burner mode, a plurality of powered open flame surface burners can provide even heat from each of the burners as a result of burner flames that provide substantially complete combustion close to the burner outlets in short, stable flames that are unaffected by an adjacent downdraft exhaust or other outside influences.  In the atmospheric mode, the gas burners can operate without  a downdraft exhaust.  The  gas range can meet agency requirements in both the powered mode and atmospheric mode of  operation  and  can be inherently fail-safe in the event of a power failure in the downdraft exhaust system.  The gas range can be economically and easily manufactured and assembled, with burner controls arranged for convenient operation at one side of the range burner box for the plurality of burners.

Abstract: A  liquid soap dispenser  is disclosed having a permanent housing which permits simplified insertion and replacement of disposable fluid reservoirs.   The housing includes and actuator assembly which is cycled by a lever between first and second positions.   The actuator assembly is configured to couple to a valve assembly on the reservoir so that when cycled,  the valve assembly is actuated  in sliding movement to dispense a quantity of fluid.   The actuator assembly includes a pair of resiliently deformable fingers  which  act  to  secure the valve  assembly  to the actuator assembly for sliding movement therewith.   If on insertion  of  a  replacement  reservoir,  the  reservoir  is positioned uncoupled from the actuator assembly,  on first cycling  of  the  actuator assembly the  fingers  deform to permit movement of the actuator assembly relative to valve assembly and move towards a coupled orientation.   In the coupled orientation,  the fingers return to an undeformed configuration securing the valve assembly to the actuator assembly.

Abstract: A steel material for coloured springs is formed with a metallic deposit on the surface. The metallic deposit contains copper, zinc, and chromium. In an annealing process, copper and zinc diffuse in the deposit to exhibit a gold colour tone while chromium is oxidized to exhibit a dark gray colour tone. The combination of these colour tones exhibits a beautiful black colour tone which is distinguishable from a normal spring. The deposit improves the formability in the spring shaping process.
