Abstract: CONTROL APPARATUS USED FOR A REFRIGERANT CIRCUIT HAVING A COMPRESSOR WITH A VARIABLE            DISPLACEMENT MECHANISM          ABSTRACT OF THE DISCLOSURE       An automobile air conditioner system including a refrigerant circuit having a condenser, expansion element, evaporator and wobble plate type compressor with a variable displacement mechanism. Two passages communicate between the crank chamber and the suction chamber in the cylinder block. A bellows is disposed in a first passage and controls the communication between the crank chamber and the suction chamber response to crank chamber pressure. A control valve is disposed in the second passage and controls communication between the crank chamber and the suction chamber in the second passage in response to a signal representing the temperature of the air immedi-ately leaving from the evaporator. An electric clutch is mounted on the compressor in order to intermittently transmit the rotational motion of an automobile engine to the drive shaft of the compressor in response to the signal. The automobile air conditioning system is provided with a demist switch for preventing the reduction of visibil-ity through the windshield of the automobile. The operation of the control valve overrides the operation of the bellows without regard to the temperature signal when the demist switch is turned on.

Title: Measuring a gap between a tube and a float
Inventor: MERSCH STEVEN H
IPC: G01B11/14
Filed: 1990-06-26
Granted: 1994-02-01
Abstract: ABSTRACT       MEASURING A GAP BETWEEN A TUBE AND A FLOAT     An apparatus or method determines the gap between an assembly of a tube and a cylindrical float located substantially   concentric   to   the   tube.     An elliptically polarized light beam at the wavelength for which the materials of the tube and the gap are transparent or translucent is along an optical axis. The  index  of  refraction  of  the  tube  and  float materials are greater than the index of refraction of the gap material.  Means translates and rotates the assembly  along  and  about  its  longitudinal  axis producing an illumination.   A light filtering means along  the  optical  axis beyond the  assembly blocks light of the illumination reflected by the assembly and refracted by the tube, the gap between the tube, and the float and the float and transmits light of the illumination refracted by the tube and the gap between  tube  and  float.  Light  detection  means receives  transmitted  light  and  signals  a  signal processing   means.    The   method   has   steps   of transmitting the monochromatic beam of elliptically polarized  light  along  the  optical  axis  to  the assembly, focusing the beam of light, translating and rotating the assembly through the light, producing an illumination,  filtering the illumination by blocking illumination reflected by the assembly and refracted by the float, the tube and the gap between the tube and  the  float  and  transmitting  the  illumination refracted by the tube and the gap between the tube and the float.

Filed: 1990-12-18
Granted: 1998-04-28
Abstract: A grating mat assembly is disclosed, which is of a generally rigid construction, as distinguished from an articulated, roll-up construction. Unlike conventional rigid grating mats, the structure of the present invention comprises a plurality of slot-like sections joined edge to edge in a manner providing for sufficiently rigidity for manufacture, handling and installation, while eliminating the customary longitudinally extending locking bars, utilized in more conventional grating mat assemblies, which add significantly to the cost of manufacture thereof. The slot-like mat sections of the new design are of extruded construction, formed with a horizontal upper ball, widely spaced vertical end walls, and one or more intermediate vertical walls. The vertical walls support the upper wall substantially above a base surface. The opposite vertical end walls of the slot-like sections are formed with tongue and groove structures, such that a pair of adjacent sections interfit to provide positive horizontal alignment. Adjacent slot-like sections are secured tightly together either by way of the tongue and groove structure, or by separate means.

Title: Method of layer stripping to determine fault plane stress build-up
Inventor: WINTERSTEIN DONALD F
IPC: G01V1/28
Filed: 1991-06-21
Granted: 1997-08-12
Abstract: A method for analyzing seismic shear wave data, using a layer stripping technique, to determine fault plane stress build-up is disclosed.  Polarization directions of shear wave data, from either a vertical seismic profile or from surface reflection data, are analyzed, and time lags between fast and slow split shear wave are determined.  Natural polarization directions of and time lags between the split shear waves in an upper layer are determined above the shallowest depth where data cues suggest polarization changes take place.  Source and receiver axes of the data below the depth of polarization changes are rotated by an azimuth angle, to bring the axes into proper alignment.  A static time shift is then applied to eliminate the time lag in the upper layer above the depth where polarization changes were indicated.  Shear wave polarization azimuth angles, and time lags between the shear waves are determined for the depth of investigation, and are compared to the strike of a nearby fault.  The procedure is repeated at a later time to evaluate any changes in the azimuth angles or time lags.

Title: Method and apparatus for producing groups from different printed products
Inventor: MEIER JACQUES
IPC: B65H39/045
Filed: 1992-04-16
Granted: 1998-09-15
Abstract: The inventive method and apparatus serve to combine into groups different printed products supplied as continuous flows (1, 2, 3 etc.), on at least one grouping section (10.1/2/3), in which each group can have a composition of in each case one product from different supply flows corresponding to a predetermined group sequence.  The production of faulty groups is prevented, in that in the supplies errors are detected at an early stage, so that groups affected by an error, are not formed in the predetermined cycle and are instead displaced by one cycle.  The group flow leaving the method consequently contains only gaps and not faulty groups.  For performing the method between the supplies (63.4/5) of products and the grouping (10.1/2) are introduced a supply control, a supply buffer storage and a controlled delivery. The means (64.2/3/4 etc.) for performing these three method stages are constituted by conveyors with cams or drivers, which are interconnected with a drag connection and which are moved by two substantially independently controlled drives on a continuous guide.  The drivers are controlled following an acceptance point at which they have accepted a product from the supply unit (63.4/5) and faulty products are recorded.  They then pass into a buffer storage space and leave the latter through a controlled delivery point, where they deliver the product into the grouping.

IPC: C07F9/09
Filed: 1992-07-03
Granted: 2001-09-04
Abstract: A process for the preparation of C14 - C18 alkyl-phosphocholines comprises reacting an n-alkanol having a chain length of C14 to C18 with phosphorus oxychloride in a single reaction vessel. The product obtained is reacted with a choline salt in the presence of a basic substance, without isolation and purification, in an inert solvent, to form a corresponding phosphoric acid diester chloride. The phosphoric acid diester chloride is hydrolyzed to obtain the alkylphosphocholine. Purification of C14 - C18 alkylphosphocholines is performed by adding to a solution of an alkylphosphocholine, in a solvent selected from the group consisting of anhydrous alcohols with 1 to 5 carbon atoms, water and any mixture of said alcohols with or without water, a mixed-bed ion-exchanger, or successively or simultaneously at least one ion-exchanger selected from the group consisting of an acid ion-exchanger and a basic ion-exchanger. The solution and the ion-exchanger are stirred together, and the solution is separated from the ion-exchanger to recover purified alkylphosphocholine.
