Patent CA-1290524-C (CA)
Title: Method of precision volumetric control of a moldable material in an injection molding process
Inventor: BUJA FREDERICK J
IPC: B29C45/80
Filed: 1988-11-02
Granted: 1991-10-15
Abstract: METHOD OF PRECISION VOLUMETRIC CONTROL OF A MOLDABLE       MATERIAL IN AN INJECTION MOLDING PROCESS        ABSTRACT OF THE DISCLOSURE A method of operating an injection molding machine having a pair of separable mold elements forming a mold cavity therebetween with means for opening and closing the mold elements with means for introducing a moldable material into the mold cavity at a first pressure and for exerting a second pressure on the moldable material as it cures in the cavity.  The method controls the molded product and comprises the steps of closing the mold elements and introducing a moldable material into the mold cavity.  The separation of the mold elements is measured during the injection of the moldable material and a predetermined separation of the mold elements is detected.  Upon detecting the predetermined separation the pressure is changed from the first pressure to the second pressure and the separation of the mold elements is continued. Measurement of mold element separation is continued and the cessation of the increase in the separation of the mold elements is detected.  A determination is made whether or not the cessation occurs within a predetermined separation window.  If the cessation is not within the window a signal is generated to indicate that the cycle has exceeded the product limit.  If the cessation is within the window then the cycle is continued and the second pressure is maintained until the moldable material has cured. The mold is then opened.

Title: Preparation process of cinnamate ester
Inventor: TAKAKI USAJI
IPC: C07C69/618
Filed: 1988-12-23
Granted: 1992-11-24
Abstract: ABSTRACT OF THE DISCLOSURE    An improved process is disclosed for preparing a cinnamate ester by reacting a styrene selected from the group consisting of styrene,  alkyl derivatives of styrene, and styrene derivatives containing, on the automatic ring, one or more substituent which do not impair the reaction and alcohol, carbon monoxide, and oxygen in the presence of palladium metal or a compound thereof and a copper compound as a catalyst.  The improvement includes blowing a feed gas mixture containing carbon monoxide and oxygen into a reaction mixture initially comprising the selected styrene, the alcohol and the catalyst in a reactor to react the reactants.  A gas flowing out of the reactor and containing vapor formed by evaporation of liquid components in the reactor is then passed through a condenser; recirculating the resulting condensate is then recirculated back to  the  reactor while the  remaining  gas  is discharged.  Finally, a gas selected from the group consisting of a portion of the gas thus discharged and a suitable gas selected from the group consisting of an inert gas and carbon dioxide, provided separately, is blown into the reaction mixture through an inlet feed zone which is different from the inlet zone for the feed gas mixture.  This increases the evaporation rates of the liquid components in the reactor, so that heat evolved inside the reactor is removed.

Granted: 1992-03-31
Abstract: File 8332-193 Abstract       TRANSISTOR MATRIX SHIFTER      The present invention provides an expandable ECL matrix shifter which has very few interconnecting wires.  The shifter can perform a multicolumn right shift or a multicolumn left shift in one cycle, and it has independent wrap and fill capabilities.  Two 2 to 1 multiplexers are provided for each bit position of the input signals.  The input signals provide one of the inputs for both of the multiplexers.  The second input of each multiplexer is a signal indicating what type of fill is desired.  The shifter has horizontal data input lines, vertical data output lines, and diagonal select lines.  A bipolar transistor is located at each intersection of a data input line and a data output line.  These transistors selectively connect the data input lines to the data output lines in response to signals on the diagonal select lines.  Each horizontal data input line is divided into two parts.  The division of the data input lines into parts is along a major diagonal of the matrix. The parts of the data input lines on one side of the major diagonal are activated by the output of one of the multiplexers, and the parts of the data input lines on the other side of the major diagonal are activated by the outputs of the second multiplexer.

Abstract: Abstract of the Disclosure An internal water drainage system for an interconnected hollow structural assembly within a railroad pressure discharge hopper car or the like is disclosed.  To facilitate water drainage throughout the interconnected hollow structural assembly following hydrostatic pressure testing of the car, water draining passageways are provided in the hollow structural members in an area of juncture between the members, at least along a lowermost extent of each of the hollow structural members.  The water draining passageways are constructed to communicate with a water drain opening provided in the shell of the railroad car, in order to afford gravity flow of water through the hollow structural members and evacuation from the railroad car.  A method for hydrostatic pressure testing of a railroad car is also disclosed in which gravity flow evacuation of water through the hollow structural members is achieved by utilizing gravity flow of water throughout.  In both the aforementioned assembly and method, water deterioration, corrosion, and the like after hydrostatic pressure testing are substantially minimized or totally eliminated.

Title: Electronic scratch filter for bowed instruments
Inventor: MCCLISH RICHARD E D
IPC: H03H9/52
Filed: 1989-09-05
Granted: 1992-06-16
Abstract: ABSTRACT OF THE DISCLOSURE            The tone signal from a transducer monitoring the music vibrations of a bowed musical instrument contains an objectionable friction noise component which is removed by passing the tone signal through a high-pass filter having a variable cutoff frequency which is controlled by a pitch detector monitoring the fundamental frequency of a played note in the tone signal. The cutoff frequency of the filter is kept slightly below the fundamental frequency of the played note to avoid altering the tone color of the tone signal. When no fundamental frequency is detected by the pitch detector, the cutoff frequency of the filter remains at a pre-determined minimum which may be adjustable by the musician for best effect when strings are both bowed and plucked. The filtered tone signal may be applied to the pitch detector in order to increase the accuracy of the pitch detection process and thus increase the accuracy of the noise reducing characteristics of the system.
