Abstract: ABSTRACT      A control system for regulating operation of a heat pump includes a basic timer circuit which is utilized in different ways for different purposes.  The system senses pressure across the outdoor coil, outdoor temperature, temperature in the liquid line to and from the outdoor coil, and temperature of the compressor discharge line.  The control system initiates a defrost cycle for the outdoor coil responsive to a high static pressure across the outside coil, at the same time that the liquid line temperature is below a preset temperature.  The defrost cycle is terminated when the liquid line temperature reaches a given temperature or when that liquid line temperature has been at a lower temperature for a certain time interval as determined by the basic timer circuit.  When the compressor is shut down, the timer is also started to ensure that the compressor is not brought back on before the expiration of the basic shut-down time interval.  In addition the compressor cannot be operated when the outside temperature is at or below whatever temperature is determined by the standby heat setting.  The compressor likewise cannot be operated when there is a second call for defrost within a given time interval, or a high temperature in the compressor discharge line.  The compressor cannot be restarted after a power failure until a preset time interval has elapsed.

Abstract: DIGITAL PHASE LOCK LOOP CIRCUIT               ABSTRACT OF THE DISCLOSURE      Herein disclosed is a digital phase lock loop circuit wherein the phase and the frequency of an output clock pulse of the circuit are made to instantaneously coincide with the phase and the frequency of an input clock pulse of the circuit.  The digital phase lock loop circuit includes a fixed frequency generator circuit, an output frequency divider to which a standard clock pulse from the fixed frequency generator circuit is supplied via an inhibit gate, an output clock pulse frequency divider which divides the frequency of the output clock pulse from the output frequency divider, a phase comparator to which the input clock pulse, the divided clock pulse from the output clock pulse frequency divider and an inhibit pulse generator to which the output of the phase comparator are supplied, for supplying the inhibit pulse from the inhibit pulse generator to the inhibit gate.  According to the present invention, a clear pulse generator is provided for the purpose of forming a clear pulse which clears the contents of the output frequency divider and the output clock frequency divider.  Such clear pulse is generated during a condition when the time difference between a first occurrence at which the frequency division of the output frequency divider is actuated by the standard clock pulse after the output frequency divider and the output clock frequency divider are cleared by the clear pulse, and a second occurrence at which the frequency division of the input frequency divider is actuated by the input clock pulse, is smaller than a predetermined period of the standard clock pulse.

Abstract: ABSTRACT OF THE DISCLOSURE      A plurality of synthetic fibrous textile materials such as polymeric yarns and staple fibers are textured by a procedure which imparts a variety of spaced deformations in a random sequence.  The fibrous textile materials are fed between two opposed pressure surfaces, one of which has a raised pattern of closely spaced pyramids while the other is made of a resilient material having a meshing pattern of pyramid shaped depressions.  The textile material is maintained at an elevated temperature during its passage between the pressure surfaces and is then cooled to give a permanently textured product.

Abstract: ABSTRACT OF THE DISCLOSURE:     A book type document is placed on a glass platen face down and scanned by s reciprocating optical system one or more times to produce one or more copies respectively.  A retractable convey-or comprising an endless belt is moved onto the platen to automati-cally feed a sheet document inserted thereinto onto the platen for scanning.  Where only one copy of a sheet document is requir-ed, the optical system is maintained stationary and the sheet document is fed by the conveyor over the platen at the proper speed, thus enabling rapid copying of a large number of sheet documents.  The magnification is variable through adjustment of the positions of the elements of the optical system when held stationary and the speed of movement of the document by the conveyor.  The conveyor feeds a sheet document onto the platen at high speed and the optical system is reciprocated to scan the document a plurality of times where a plurality of copies of the document are required.

Abstract: ABSTRACT     An exhaust system for withdrawing exhaust gases as well as combustion materials from a crankcase of an engine for a U-shaped straddle carrier includes an engine exhaust line which has an exhaust outlet adjacent the engine and an elongated pipe ex-tending from the outlet of the exhaust line to an area above the frame structure for the carrier.  A tube leads from the crank-case vent outlet to the exhaust line and has an open end which is located within the line spaced inwardly from the exhaust outlet of the exhaust line.  The enlarged pipe creates a venturi effect adjacent the outlet of the exhaust line which produces a negative pressure at the outlet end of the tube and sucks the combustible materials from the crankcase vent into the exhaust line where they are ignited by the high temperature exhaust gases and are burned before exiting from the enlarged pipe.

Abstract: ABSTRACT:       A record carrier is described having an optically readable information structure of trackwise arranged ares.  If the adjacent tracks differ from each other in that their areas have different a phase depth, the tracks can be situated neater each other and can still be read separately.  The information density can then be increased.         The record carrier is read with the aid of two detectors which are situated in the far field and which are offset from each other in the track direction.  The signals from these detectors are added to and subtracted from each other respectively for reading tracks with a larger phase depth and tracks with a smaller phase depth.
