Title: Circuit for correcting the distortion of read signals from a pcm transmission apparatus, particularly from a digital audio disc
Inventor: SCHOLZ WERNER DIPL ING
IPC: H04B14/04
Filed: 1981-07-02
Granted: 1984-11-22
Abstract: In a circuit arrangement for the correction of falsified sample values in a PCM transmission system, which arrangement includes an interpolation member connected for deriving a corrected value to replace each falsified value by interpolation between sample values preceding and succeeding the falsified value in time, the interpolation member is provided with components connected for deriving each corrected value by effecting a weighted combination of the sample value appearing at the output of the interpolation member and preceding the falsified value in time and the next unfalsified sample value succeeding the falsified value in time in order to perform an at least approximately linear interpolation between sample values which are thus combined.

Title: Method of rendering documents resistant to photocopying and anticopying paper therefor
Inventor: GARDNER NORMAN A
IPC: G03C5/08
Filed: 1983-08-17

Abstract: A document has information appearing thereon, with at least a portion of the information being located on a front face of a portion of the document. The front face portion has a colour with a sufficiently low reflection spectral response to render the document portion substantially incapable of being photocopied in an information-readable manner. The document portion is capable of transmitting visible light from the rear face to the front face to cause sufficient contrast between the relatively non-translucent information and the transmitted light to enable the information to be read by a human eye viewing the front face of the document when visible light is transmitted through the document from the rear face to the front face.

Title: Method and apparatus for controlling azimuthal drift of a drill bit
Inventor: ANDERS EDWARD O
IPC: E21B7/06
Filed: 1984-07-16
Granted: 1987-04-09
Abstract: A method of and apparatus for controlling the azimuthal drift of a drill bit in an inclined well bore is described. The method comprises prestressing a drill collar member in torsion to adjust the angle in the horizontal plant that the drill bit makes with the longitudinal axis of the well bore when the drill collar is subjected to the gravitational, axial, and torsional forces of the drilling operation. The drill collar includes an inner tubular member and an outer tubular member. The two are held against relative rotation at one end. The desired torque is placed in the members by rotating the other ends of the members relative to each other in the desired direction. A splined member engages grooves in the inner and outer surfaces of the members to hold the members in their prestressed state.

Title: Television frame signal synchronizing circuits
Inventor: WILKINSON JAMES HEDLEY
IPC: H04N5/04
Filed: 1984-05-09
Granted: 1987-11-05
Abstract: A television frame signal synchronizing circuit comprises a presettable cyclic counter and a maximum count detector, a clock pulse generator for supplying clock pulses to the counter, a store for storing the count of the counter, and a source of reference frame pulses to which input frame pulses are to be synchronized, each reference frame pulse causing the count stored in the store to be loaded into the counter. A television signal processor is capable of adjusting the timing of television signals passed therethrough in dependence on a reverse frame pulse, the carry signals from the counter forming reverse frame pulses for supply to the television signal processor for adjusting the phase of the television signal passed therethrough, the television signal including the input frame pulses at least some of which are derived and supplied to the store which thereupon stores the count of the counter. The phase of the television signal is therefore adjusted until the input frame pulses are in synchronism with the reference frame pulses.

Title: Esterification of carboxylic acids containing phenol groups
Inventor: NESTLER HANS JURGEN DR
IPC: C07C69/732
Filed: 1984-09-27
Granted: 1989-12-14
Abstract: Carboxylic acids containing phenol groups are esterified by means of (C1-C3)-alcohols in the presence of acid catalysts without the phenolic hydroxyl groups being esterified at the same time by continuously metering an excess of a water-containing (C1-C3)-alcohol into a boiling hot solution or suspension of the phenol-containing carboxylic acid and of the catalyst in a non-water-miscible solvent (for example xylene) and at the same time distilling off a ternary solvent/alcohol/water mixture via a water separator, the metering rate being such that an aqueous bottom phase separates out in the receiving flask and the water content of the alcohol being so apportioned as not to breach the bottom limit of 0.1% or the upper limit of 1% (based on the contents of the reaction vessel) at any time in the course of the reaction. In this process, the esterification products are obtained free of major impurities and frequently can be used further without further purification.

Abstract: This machine can serve as a compressor or motor and, more specifically combines a compressor and a motor to constitute an internal combustion engine with compressed air injection. A toothed rotor (12 or 54) is rotatable in a fluid displacement chamber and in sealing contact with a sealing rotor (8 or 52) having peripheral cavities for receiving the teeth (14 or 57) of the toothed rotor. Both rotors are axially curved, so as to better resist differential axial thrust exerted on the same and, therefore, maintaining better sealing contact. The teeth of the toothed rotor are generally of a hemispherical shape to facilitate the provision of effective sealing segments. When used as an internal combustion engine, a combined fuel injection and ignition device (27, 28, 29) is provided enclosed within a sleeve (35) rotatable within the engine housing (4), the sleeve having a lateral opening (41) which can be made to selectively register with one of two housing passages (43) opening in two adjacent fluid displacement chambers (17), with the result that the engine can be reversed by the simple rotation of the ignition device enclosing sleeve.
