Title: voltage controlled elastic wave delay line oscillator - has thick film circuit on ceramic substrate with capacitor trimmers for rest frequency
IPC: H05K1/18
Filed: 1980-03-11
Abstract: The oscillator uses a surface bulk elastic wave delay line. The device may be used in a telecommunications receiver with a centre frequency of 200 mHz with plus and minus 3 kHz modulation and a spectral purity in excess of -100dB. The circuit is produced using discrete components on a ceramic substrate. The output of an amplifier is fed back to the input through an electro mechanical delay line, produced from BT or AT cut quartz, a voltage controlled phase difference circuit driven by the frequency control voltage and a 3dB coupler and phase difference circuit with adjustable capacitors which are used to trim the rest frequency and the oscillator. The voltage controlled phase difference uses voltage controlled variable capacitance diodes and toroidal ferrite cored inductances. The delay line is impedance matched by transformers to 50 phms for both input and output and the output is taken by transformer from the loop signal at a level and at most -10dB to the loop signal.

Title: IC-engine in V-formation - has combustion chambers in cylinder head on centreline of both rows of cylinders
Inventor: KRUGER HERMANN
IPC: F02B75/22
Filed: 1980-06-04
Abstract: The engine has two rows (2, 4) of cylinders. The rows are inclined to each other to give a V formation of cylinders. Along the length of the engine the cylinders (2, 4, 3) alternate between one row and the other. Each cylinder has a combustion chamber (8, 9, 10) in the underside of the cylinder head above the point reached by the piston.

Title: Powdered whey prodn. - by lactose-crystallisation and spray drying
Inventor: BEUNEU PIERRE
IPC: C13K5/00
Filed: 1980-11-10
Abstract: Prodn. of powdered prods. from whey or other lactose solns. is carried out by (a) crystallising part of the lactose in a continuous evaporative crystalliser; (b) passing the resulting crystal slurry through a continuous basket-type centrifuge to separate lactose crystals from mother liquor; and (c) recycling part of the mother liquor to the crystalliser and spray drying the rest.

IPC: A44C5/10
Filed: 1980-11-27
Abstract: The metal band (10) composed of elongated elements (1, 2) connected by means of pins (4) has two rows of elements of different types, the elements (1) of one type being constructed symmetrically with respect to the elements (2) of the other type. The elements (1, 2) of each row are arranged offset and in parallel with each other, each row of elements (1, 2) forming a sequence of steps. The two sequences of steps interlock. Each element (1, 2) has three holes (9, 9', 9'') through which the pins (4) are passed. Each two elements (1, 2) are in each case only connected to each other by a single pin. By virtue of corresponding play between the pins (4) and the holes (3, 9), the metal band (10) is flexible in its longitudinal direction and can be twisted about its longitudinal axis, and, as a result, when the metal band (10) is used as a jewellery band, it can follow the change in shape of the forearm.

Patent FR-2500969-A1 (FR)
Inventor: NAJMAN MICHEL
IPC: H03G3/00
Filed: 1981-02-27
Abstract: An amplifier is provided comprising an input transistor and an output transistor connected in series between two power supply terminals. The biassing of the base of the output transistor is determined by an impedance bridge coupling one of the supply terminals to the output of the amplifier. A "parallel resistor-capacitor" cell, coupled between the output transistor and the output of the amplifier, plays the role, with the base-emitter diode of the output transistor, of a detector circuit. This arrangement, by increasing the voltage at the terminals of the resistor of the cell depending on the detected signal, increases correlatively the current supplying the transistors as a function of the amplitude of the signals to be amplified.
