Patent CA-2108946-A1 (CA)
Inventor: HUFFINGTON JEFF
IPC: F24C7/08
Filed: 1993-10-21
Abstract: A control system for dual oven resistance heaters (BAKE, BROIL) has opposite sides of each heater connected to a common side of one of a pair of SPDT switching relays such that no current flows to the heaters when both relays are in a common state of energization/de-energization. A microcomputer receives a signal from the oven temperature sensing and signals separate switching devices to selectively energize/de-energize one of the relays to switch on the desired heater. Separate comparators also receive the temperature sensor signal; and, in the event of failure of the microcomputer or switching devices with a heater "ON", the comparator is operative to bring the relays to acommon state, preventing current flow to either heater.

IPC: G01N21/90
Filed: 1994-01-06
Abstract: ABSTRACT      Light-transmitting plastic and/or glass bottles are tested at  a station where  selected portions  of  their internal surfaces scatter radiation issuing from a beam of monochromatic  radiation.    The  scattered  radiation  is intercepted and monitored for the generation of signals which denote the presence or absence of impurities on the selected portions of the internal surfaces and/or certain substances in the walls adjacent the selected portions of the internal surfaces of tested bottles.  Such signals are processed,  and  the  processed  signals  are  utilized  to classify the bottles according to their defects and/or to segregate unsatisfactory bottles from acceptable bottles and/or to segregate glass bottles from plastic bottles and/or  to  classify  satisfactory  plastic  bottles  in accordance with the nature of their plastic materials.  The scattered radiation can constitute Raman, Rayleigh and/or fluorescence radiation.

Title: Method and device for boning abdominal sections, containing spinal parts, of animals for slaughter
Inventor: PASSCHIER BOB
IPC: A22C17/00
Filed: 1992-08-11
Abstract: The invention relates to a method and a device for boning carcass portions of an animal for slaughter. Said carcass portions are in particular abdominal sections on part of the inner surface of which lies a row of more or less encapsulated ribs forming the bone parts which are to be removed. When the method is performed, each abdominal section is held in place and supported, each abdominal section being passed along a number of processing units.  According to the invention, the ribs are weakened locally between the ends, and then bent over at a subsequent processing unit so that they break at the location of the weakened areas. By this method, it is possible to remove by machine at least one of the two rib parts formed in this manner.

Title: Shrink film wrapper
Inventor: HALLQVIST LENNART
IPC: B65B41/18
Filed: 1994-05-06
Abstract: ABSTRACT OF THE DISCLOSURE     The disclosure relates to a method of shrink film wrapping one or more objects (12) in one or more rows. The objects are caused to be surrounded by two film webs (1, 4), which are sealed together by means of a sealing jaw (14). The objects (12) are moved in towards the two film webs (1, 4) by means of a pusher which, on its completion of the infeed movement stroke, stretches the two film webs (1, 4) in that the film webs are fixedly retained by each one of a hose brake (7, 8). When the sealing jaw (14) executes its downward stroke for completely shrouding the films (1, 4) around the objects (12), the sealing jaw (14) finally stretches the upper film (1). The film (1, 4) projecting outside the objects (12) is shrunk by means of hot air nozzles directed towards the objects (12).

Title: Dental floss provided with chemotherapy agents
Inventor: SIMIONATO LUIZ BELLINO
IPC: A61C15/04
Filed: 1994-06-07
Abstract: Dental floss provided with chemotherapy agents, including wax that is emulsible upon contact with saliva. State of the art dental flosses achieve an efficient release of active agents within the oral environment, by using soluble waxes, but said solution decreases comfort of application since there is a de-crease in the levels of sliding and penetration between the teeth, in comparison to the use of insoluble waxes. The use of said emulsible wax allows for an efficient release of the chemotherapy agent through the oral environment - preferably fluoride ions - while maintaining the same levels of sliding and penetration between teeth as are obtained with insoluble wax.

Title: Decision feedback equalizer method and apparatus
Inventor: BLACKWELL STEVEN R
IPC: H04B3/04
Filed: 1994-06-01
Abstract: A decision feedback equalizer is suitable for use with a bipolar return-to-zero receiver. The equalizer determines an output Y(n) (160) based on a compensated received value X(n) (104) and a correction factor, D(n) (141). After receiving X(n), the equalizer then forms an equalized received value X'(n) (107) based on combining X(n) with D(n). The equalizer then determines the output value Y(n) based on comparing X'(n) with a positive threshold, V1 and a negative threshold, V2. When Y(n) is determined to be zero, the equalizer adjusts the stored correction value D(n) by a predetermined value, .DELTA., based on whether X'(n) is positive or negative.
