Abstract: Abstract An optical recording apparatus employs a first light spot for recording predetermined information along a guide groove provided in a recording medium.  Two second light spots and two third light spots are arranged along the guide groove in such a manner as  to deviate from the center line of the groove.  The second light spots are arranged in an area with no information recorded therein, while the third light spots are arranged in an area with information recorded therein.  The position of the first light spot, i.e. tracking of the groove, is controlled on the basis of the difference between the quantities of reflected light from the second light spots and the difference between the quantities of reflected light from the third light spots.  The result is improved tracking precision.

Abstract: Abstract A switching assembly is disclosed for mounting on the face of a pedal to effect switching when said pedal is pressed comprising a generally flat base adapted for attachment to a pedal, a plurality of movable switching elements supported ultimately on the base, each of the switching elements arranged to assume a plurality of positions to implement distinct switch set-tings.  The assembly includes a generally flat shaped actuator supported on the base and constrained to move backward and forward with a single degree of freedom in a plane parallel to the pedal face.  The actuator has actuating means arranged for moving the movable switching elements as the actuator moves forward, and a cam surface positioned and arranged so that pressing thereon urges the actuator to move forward.  A resilient element is arranged to urge the actuator backwards and a generally flat pressure member is supported on the base in a manner permitting motion of the pressure member toward and away from the pedal face while constraining motion parallel to the pedal.  The pressure member is adapted for receiving control pressure applied by an opera-tor to the pedal and has cam surface positioned and arranged so that when control pressure is applied to the pressure member by an operator the pressure member cam surface presses on the actuator cam surface to urge the actuator forward.  The cam surface extends to areas close to the periphery of the pressure member so that the cam action is effective irrespective of the area of the pressure member pressed by an operator.  The pressure member is loosely supported on the base to permit motion of the pressure member toward the pedal without binding irrespective of the area pressed by an operator.  The switching assembly is effective in changing switch settings of the switching elements in a well defined predetermined order as the pedal is pressed irrespective of the point of application of control pressure on the pressure member.

Abstract: ABSTRACT                 BINARY LOGIC STRUCTURE EMPLOYING PROGRAMMABLE LOGIC ARRAYS AND USEFUL               IN MICROWORD GENERATION APPARATUS           Binary logic structure is described which requires less space on an integrated circuit chip.  This structure includes an encode programmable logic array responsive to a first group of binary input signals for producing a smaller number of binary signals which are encoded to identify different binary value combinations for the first group of binary input signals.  This structure further includes a decode programmable logic array responsive to a second group of binary input signals and to the encoded binary signals produced by the encode programmable logic array for producing binary output signals representing logical functions of binary input signals in both the first and second groups.  The chip space occuppied by the encode pro-grammable logic array is less than the additional chip space that would be required if the encode and decode programmable logic arrays were replaced by a single programmable logic array for receiving all the binary input signals in both the first and second groups. When used to provide microword generation apparatus for a microprogrammed digital system, the encode program-mable logic array is responsive to a plural-bit system instruction for producing a plural-bit instruction identification signal uniquely representative of such system instruction but having a smaller number of bits than the system instruction.  In such case, the decode programmable logic array is responsive to the instruc-tion identification signal and to number signals pro-duced by a sequence counter for producing a sequence of microwords needed to execute the system instruction.

Abstract: ABSTRACT:          Method and computer tomography device for determining a tomographic image with elevated resolution.     The invention relates to a computer tomography device, in which the row of detectors has been rotated through the quarter of a detector angle (.DELTA.?/4) with respect to the X-ray source. The invention proposes to filter (or convolute) the selected parallel measurement values measured in a given direction instead of doing so with all the se-lected measurement values measured in parallel and anti-parallel directions. Although a loss then occurs for the information in the range of higher frequencies, this loss is not significant. Due to the frequency-limiting influences of the width of the measuring beam, interpolation in the backprojection device and image element size in the image matrix, the overall frequency response curve of the computer tomography device is not essentially worse. With the use of the present invention, however, the calculating time required for filtering is reduced by a factor 2 and the current measurement values can be processed in a simpler manner (pipeline processing).

Abstract: ABSTRACT       ARRANGEMENT FOR DETERMINING CHARACTERISTICS OF      MAGNETIC PARTICLE DISPERSIONS          For determining characteristics of coating compositions including magnetic particles, the coating composition is subjected to an alternating magnetic field of selectively variable frequency.  The field induced by the coating composition after energization is recorded, and thus the susceptibility of the coating composition is measured. Depending on the selected frequencies, conclusions can be made regarding the degree of dispersion, particle density, and viscosity of the coating composition.  The frequency is varied between 1 and 100 cups, and the field intensity of the energizing field should be lower than about 10 Oersted. The coating composition may be static or flowing in a container pipe or conduit which is surrounded by field coils and a measuring coil.

Abstract: RECOVERY OF VISCOUS HYDROCARBONS BY   ELECTROMAGNETIC HEATING IN SITU                ABSTRACT OF THE DISCLOSURE A method of electromagnetic heating in situ recovers liquid hydrocarbons from an earth formation containing viscous hydrocarbonaceous liquid and water in an inorganic matrix where the formation is substantially impermeable to fluids under native conditions.  A block of the earth formation is substantially uniformly heated with electromagnetic power to a temperature at which the viscous hydrocarbonaceous liquid is relatively fluid and a portion of the water vaporizes to water vapor at a pressure sufficient to overcome the capillary pressure of the liquid in the matrix.  Water vapor thereupon escaping from the block under such pressure is recovered with hydrocarbonaceous liquid driven thereby.  The magnitude of the electromagnetic power is controlled to limit the current recovery ratio of water vapor to hydrocarbonaceous liquid below a predetermined limit assuring substantial recovery of the hydrocarbonaceous liquid prior to the driving off of substantially all the water.
