Title: Process of refining saccharide crystals during food processing
Inventor: MARTIN ROBERT A JR
IPC: A23G3/42
Filed: 1990-12-11
Abstract: An ingredient formed by an improved process for incorporation into a food product.  In the improved process for producing food products, such as confections, including milk and dark chocolate, a crystalline saccharide such as sucrose, and a fat such as cocoa butter, are blended with a minor amount of water. The blend is refined, such as by passing it through the nip of at least one pair of refining rolls, to produce particles having a size less than about 50 micrometers.  The minor amount of water is effective to dissolve saccharide particles having a size less than about five micrometers.  Subsequently, the refined product can be heated and agitated to evaporate the minor amount of water.  The resulting semi-processed food ingredient is useful for producing food products having improved viscosity characteristics.

Patent CA-2042701-A1 (CA)
Title: Time-frequency mapping
Inventor: NOVAK PETER
IPC: G06F17/10
Filed: 1991-05-16
Abstract: ABSTRACT    This inventive idea relates to the application of a modified Wigner distribution as a tool for time-frequency signal analysis. This method enables to evalute the signal structure simultaneously in  the  frequency  domain  and  in  the  time  domain.  Thus  the limitations of methods working exclusively in the frequency domain or in the time domain are overcomed. Further, the method enables to evaluate instantaneous transmission of the frequency content between different signals and thus to study the relationship between different systems. Moreover, this approach does not need the assumption about linearity of the process and stationarity of the signal.   I have defined the smoothed cross discrete Wigner distribution as well as the the algorithm for the smoothed auto and cross discrete Wigner distribution.

Inventor: NEAD THOMAS E
IPC: G01D5/245
Filed: 1991-08-02
Abstract: Interface circuits for electromagnetic position transducers are provided to reduce the effects of capacitive coupling occurring in the conductive cabling between the position transducers and the associated interfaces located remotely therefrom. Capacitive coupling of excitation signals to the transducer output signals result in error signals appearing as cyclic error in measured positions. The magnitude of the coupled signals are substantially reduced by providing excitation signals symmetrical with respect to ground. The magnitude of the coupled signals are also reduced by presenting equal impedances relative to ground to the output signal return and signal paths. By reducing the effects of capacitively coupled signals, conducting cables for the excitation signals, and the transducer output signals may be incorporated in a single shielded cable.

IPC: H01R13/15
Filed: 1991-10-16
Abstract: ABSTRACT OF THE DISCLOSURE    A socket for an electric part has an electric part ac-commodating space, and a plurality of contacts arranged in parallel relation along at least two opposing sides of the space.    Each of the contacts has a contact nose portion to be contacted with a contact of the electric part accommodated in the electric part accommodating space, and a spring por-tion for biasing the contact nose portion inwardly in order to obtain a contacting pressure with the contact of the electric part.    The socket for an electric part also has a pivotable lever disposed along a row of contacts.   One end of the pivotable lever is engaged with the contact and the other end is extended outwardly of the contact from the en-gaging portion.   The pivotable lever is supported such as to be pivoted about an idle fulcrum.   The pivotable lever, when its other end is pushed down,  is pivoted about the idle fulcrum to permit the engaging portion to displace the con-tact nose of the contact outwardly against resiliency of the spring portion, so that the contact nose is separated away from the contact of the electric part.

Filed: 1992-03-12
Abstract: A  switching-type  voltage regulator of this invention comprises  a voltage  control  section  for   generating   a stabilized  voltage  by  controlling a voltage supply period from input side to output side, and a protective device. The protective device  monitors  the temperature  of  a  certain component  part or  parts  of  the voltage  control  section and convert the temperature into a voltage  to compare  with the  reference  voltage  generated  by a  reference  voltage source, and brings the output of the voltage control section to a halt  in accordance with  the result of comparison. The output of the voltage  control section is  brought to a halt regardless of the  presence  of output abnormalcy  when  the temperature  of   the  component  part  or  parts  monitored exceeds a certain level.  As  the monitoring  means,  it  is preferable  to  utilize  the  electrical  characteristic  of semiconductor  p-n  junction  changing with temperature, and a  semiconductor  diode  is  more preferable.  A  preferable halting  means  is  a  2-input  AND  circuit  where a signal representing the result of the  comparing means are inputted into  one  of the input terminals,  and  a switching control signal  to  the  other  to  control  a  switching   element.          Preferably,  a  latching  means  is  installed  between  the comparing  means  and  halting  means  to  maintain a halted condition.
