Title: Method of controlling the quality of dough during its processing
Inventor: BAN NOBUO
IPC: A21C3/02
Filed: 1990-12-11
Granted: 1996-01-02
Abstract: A method is provided of controlling the quality of dough during its processing, in which the physical properties of portions of a dough strip being continuously fed are automatically and continuously measured, to obtain the specific gravity, calculated from the dimensional and weight data, of each of the portions of the dough strip, so that the dimensional data and specific gravity can be used for processing the dough mass and for formulating raw materials for the next lot to be produced, and in which method, based on the obtained specific gravity, the thickness of a dough piece having a uniform top surface area to be stamped out by a puncher is automatically calculated by a computer and an additional stretching system adjusts the thickness of the dough strip, so that the weight of a stamped-out dough piece is automatically made uniform during the operation.

Patent CA-2066592-C (CA)
Inventor: MASRELIEZ C JOHAN
IPC: A61B17/00
Filed: 1990-09-27
Granted: 1996-07-09
Abstract: A method and apparatus for precisely controlling the temperature of a heated tip are disclosed. The temperature  of a ther-mocouple within the tip is sensed at a selected rate. The sensed temperature  is compared with a preselected temperature set by a user. The power provided to heat the tip is varied to cause the tip to achieve the selected temperature. If an AC power source is used, the temperature sensed at each zero crossing of the power source and the amount of power provided within that cycle is based on the temperature of the tip sensed within the same cycle. The duration of time that heat is applied to the probe within the cycle is varied to achieve the desired temperature. If a DC power source is used, the temperature of the tip is sensed at selected intervals. The sensed temperature controls the amount of power provided to heat the tip. The exact temperature of the tip is thus advantageously controlled to provide the desired heating.

Title: Frequency converter for a radio communications system
Inventor: HARMAN STEPHEN G
IPC: H03D7/16
Filed: 1991-05-07
Granted: 1994-11-08
Abstract: A frequency converter for a transmitter of a microwave radio communications system comprises an image reject mixer (10) for mixing an IF signal with an LO or carrier frequency signal to produce an RF signal, and a nulling circuit for providing d.c. offsets to the image reject mixer to reduce carier leak to the RF signal.  The nulling circuit includes a source (32) of phase quadrature chopper signals which are cross modulated (34) with the LO signal to produce a modulated signal, and a single-ended mixer (38) for mixing the modulated signal with part of the RF signal. The output of the single-ended mixer is low pass filtered (40) and the resulting filtered signal is cross demodulated (36) with the chopper signals to produce phase quadrature correction signals, which are integrated (44) to produce the d.c. offsets for the image reject mixer. The arrangement avoids the need for, and expense of, a subsequent carrier frequency filter.
