Patent CA-1309665-C (CA)
Title: Amplitude compressing/expanding circuit
Inventor: AKAGIRI KENZO
IPC: G11B20/00
Filed: 1988-06-22
Granted: 1992-11-03
Abstract: ABSTRACT   In an amplitude compression and expansion circuit, the amplitude compression ratio for the output signal is switchable by controlling the gain of the amplitude modulating circuit based upon the signal level of the input signal or output signal from the amplitude modulating circuit. The amplitude compression and expansion circuit utilizes an adder circuit for outputting a difference signal between the input signal and output signal and a signal processing circuit for feeding out an output signal whose signal level varies with the difference signal, and is adapted to output a summation signal of the output signals from the amplitude modulating circuit and the signal processing circuit. This allows selection of a suitable input/output characteristic for the processing circuit and an improved output signal.

Title: Rail transportation system with switches, especially a mono rail overhead system for cyclic conveyance of one or more carriers, e.g. in feeding systems
Inventor: MADSEN HOLGER
IPC: E01B25/26
Filed: 1988-11-03
Granted: 1992-10-20
Abstract: ABSTRACT:            In overhead rail systems with branching tracks, a carrier such as a feeding container can be brought to pass a cyclic transportation course when the pertaining switches are correctly operated. By the invention the carrier and the switches      are arranged in such a manner that a predestined transportation course is automatically achieved without applying any separate control of the switches, as the carrier     is provided with switchable activation cams     , which can co-operate with change-over switch arms          on each rail switch      in such a manner that the carrier     by its own movement can cause a change-over of the switch     , when this is relevant, as the activation cams      selectively are made operative and inoperative, respectively, by passing strategically placed, fixed actuator members . Hereby a cyclic course of the conveyance of the carrier can be arranged purely mechanically.

Title: Fibre optic sensors for the continuous measurement of  liquid level and other parameters
Inventor: SNOW JAMES W
IPC: G01F23/292
Filed: 1989-03-14
Granted: 1994-10-04
Abstract: ABSTRACT      A fibre optic sensor,  particularly for ascertaining fluid  levels,  utilizes  at  least  two  optical  fibres  or waveguides having at least a portion thereof embedded in a transparent substrate material of similar refractive index.          One of the fibres is coupled to a light source, the other to a light detector.  The source fibre illuminates the interior of the substrate so that light exiting the source fibre is coupled to the detector fibre when total internal reflection at the substrate-fluid interface occurs in the presence of a first fluid.   In the presence of a second fluid of higher refractive  index than the  first  fluid,  there will  be  no coupling,  due  to  the  loss  of  light  into  the  fluid  by refraction.   One mechanism   for coupling  light  into the detector fibre is fluorescence within that fibre causing it to provide a light signal which varies with the level of the second  fluid.    Several  different  embodiments,  to  achieve discrete or continuous level sensing or the sensing of other parameters, are disclosed.

Title: Advertising panels for shopping carts
Inventor: REHRIG HOUSTON
IPC: G09F23/06
Filed: 1989-05-03
Granted: 1993-05-18
Abstract: ABSTRACT OF THE DISCLOSURE       For walls of shopping cart baskets, advertising panels which include a plate element and a frame element which fits on the plate element and is releasably held in place thereon by a tab-and-slot arrangement. When held in place, a slot and a card display area which is encircled by the frame element are formed between the plate and frame elements. An advertisement display card can then be easily slid into and out of the display area through this slot. Projec-tions on at least one of the elements keep the card from falling out of place when in the area. Retrofitted and molded-in panel versions are disclosed. Plate elements of the retrofitted version can be secured together on the inside and outside of the basket wall providing inwardly and outwardly disposed display areas. The molded-in panel has its plate element molded with and recessed in from the outer sur-face of a wall of the plastic cart basket, and thus when positioned centrally on a basket side wall with the frame element held thereon, the panel does not prevent the carts from nesting. The frame ele-ment of the molded-in version, however, is preferably identical to that of the retrofitted version and is also releasably retained in posi-tion using tabs and slots. The frame and plate elements are both sym-metrical about their longitudinal axes.

Abstract: ABSTRACT OF THE DISCLOSURE     A method for determining the presence of a specific binding member bound to first particles in a liquid medium is disclosed.  The method comprises providing in combination (1) a liquid medium suspected of containing a specific binding member bound to first particles, (2) means for agglutinating the first particles in relation to the presence of the specific binding member, and (3) second particles having the same or a different specific binding member for said means for agglutinating bound thereto, thereby providing for said means to agglutinate the second particles.  Agglutination of the first and second particles are separately detectible and distinguishable by spectroscopic measurement.  The medium is incubated and agglutination of each of the particles is determined spectroscopically without separating the first and second particles.  The agglutination of the first particles is related to the presence of the specific binding member on the first particles, and the absence of agglutination of the first particles taken together with agglutination of the second particles is related to the absence of the specific binding member on the first particles.

Abstract: A process for oxygen bleaching fibrous cellulose pulp is described in which the pulp passes a first delignification zone with a pre-determined low temperature and a second delignification zone with a predetermined high temperature which is higher than that in the first delignification zone. The pulp is fed through a first verti-cal reactor containing said first delignification zone with low temperature, and thereafter through a second vertical reactor con-taining said second delignification zone with high temperature. The temperature in the first delignification zone is either main-tained at the temperature that the pulp entering for bleaching has acquired during a previous treatment before the oxygen bleaching, or as required is adjusted by the controlled supply of steam to a mixer disposed in the pipe before the first reactor. The tempera-ture in the second delignification zone is adjusted by the con-trolled supply of steam to a mixer disposed in the pipe between the two reactors.

Abstract: A method is provided for producing a membrane from polycarbonate-polyether-blockcopolymers with about 5 to 35 weight percent of repeating alkyleneethercarbonate units and about 95 to 65 weight percent of repeating bisphenol A-carbonate units, wherein the polyethyleneoxide blocks have a molecular weight from about 1,000 to 20,000, wherein the intrinsic viscosity of the copolymer is from about 180 to 300 ml/g as measured in chloroform at 25 DEG  C. and wherein the ultrafiltration rate is from about 4 to 200 ml/h.m2.mm Hg. In a first dissolving step a polycarbonate-polyether-copolymer is homogeneously mixed with a solvent at a temperature from about 80 DEG to 120 DEG  C. and in a second dissolving step the temperature is brought to about 140 DEG  to 180 DEG  C. to produce a true solution. The filtered solution is cooled to from about 20 DEG  to 50 DEG  C. and is then extruded through a nozzle into a bath comprising a nonsolvent for the polymer for precipitating the polymer. The precipitated polymer is then washed and dried. The resulting membranes improve the processes of hemodialyzing and of homofiltration.
