Patent FR-2261468-A1 (FR)
Title: Hydraulic or pneumatic servo-controlled valve - uses permanent magnet and soft iron yoke to open pilot valve
IPC: F16K31/08
Filed: 1975-02-18
Abstract: The lower part of the valve has an inlet and outlet and a valve seat which is sealed by a diaphragm. The diaphragm is provided with a small orifice which normally maintains the chamber at inlet pressure. The pilot valve seals the central hole under the load of a spring. A yoke of soft magnetic material is attached to the pilot valve. The upper part of the valve is of non-magnetic material and houses the diaphragm which carries a permanent magnet. When the top diaphragm is depressed, the pressure generated on the lower diaphragm pushes the magnet downwards. This magnet motion attracts the yoke upwards and so opens the pilot valve.

Title: Adjustably curved roller - has device for adjustably curving and holding roller in predetermined plane
IPC: B65H23/025
Filed: 1975-04-14
Abstract: Adjustably curved rod or roller used on paper machine for separating strips of longitudinally cut paper band includes a tube of a circular section and a device for holding the tube in a predetermined angular position. The device which is mounted about an axis parallel with the axis of the tube but positioned some distance apart is subjecting the tube to an adjustable load by which the tube is curved parallel to a plane projecting through its axis and the axis of the device. The tube is also stressed by a resulting force which acts in a second plane projecting through the tube axis and through a second axis parallel with the tube axis which tends to produce an un-acceptable curving of the tube in the second plane. In order to prevent this curving a second device is provided to produce an adjustable longitudinal load in the second plane to resist the resulting force.

Abstract: 1515571 Vacuum depositing semi-conductors MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 19 May 1975 [23 May 1974 7 June 1974 (2)] 21146/75 Heading C7F [Also in Division H1] In molecular beam epitaxial deposition of a compound semi-conductor the conductivity type or composition of a selected region 22 of the epitaxial layer is caused to differ from that of the remainder 21 of the layer by the selective heating, during deposition, of the region 22 by means of a beam 30 of concentrated energy such as an electron beam or laser beam. In one Example Ge-doped GaAs is epitaxially deposited on a GaAs substrate 2 using molecular beams from respective Ge and GaAs sources. Firstly a uniformly n type layer 20 is deposited on the pre-heated substrate 2 using no concentrated energy beam, but when the beam 30 is scanned across the region 22 during a second deposition stage the Ge deposited in the additionally heated region 22 becomes an acceptor (Ge being an amphoteric dopant in GaAs) and the resulting layer has a p type strip 22 in otherwise n type material 21. In another Example GaP and GaAs sources are used for the molecular beams to deposit a GaAs x P 1-x  mixed crystal. When an area of the surface is selectively heated by a beam of concentrated energy the material depositing on the selected area contains a higher concentration of P (i.e. lower value of x) than elsewhere in the layer. An Al molecular beam may additionally be used in this example. Preferred apparatus, temperature conditions, &c., are disclosed for both Examples.

Title: Ignition circuit for gas cigarette lighter - has Darlington pair oscillator which is blocked after each ignition spark
IPC: H03K3/57
Filed: 1975-06-11
Abstract: The ignition circuit, for a gas cigarette lighter, consists of a complementary Darlington pair oscillator supplied from a battery and acting as DC/DC converter. The oscillator's output is rectified and used to charge a capacitor. The capacitor is discharged by e.g. a thyristor across the primary of the voltage step-up transformer to those secondary the spark gap is connected. The capacitor (C2) discharges through a zener diode (Z) whose canode is coupled to the thyristor gate. This anode is also coupled back over two resistors (R6, R2) to the input side of the oscillator (T1, T2). A second capacitor (C1) is charged from the current through the zener diode and blocks the oscillator. This capacitor then discharges and oscillations can only be restarted by depressing the ignition button once again.

Title: Integrated semiconductor cct chip meat sink - has connecting tags of semiconductor chip bent upwards in direction of housing cover
IPC: H01L23/057
Filed: 1975-08-28
Abstract: The integrated circuit heat sink incorporates a housing, on whose base plate (2) is mounted the semiconductor chip (1), the housing being closed by cover plate (3). Instead of being bent down alongside the base plate, the dual-in-line terminal tags (4) are bent down alongside the cover plate so that when the semiconductor integrated circuit chip is mounted on a printed circuit board the semiconductor chip is upside down beneath the tags and the cover plate is between the tags, and not as usual above them. This configuration improves heat dissipation by making the base plate readily accessible.
