Title: Electronic key for mains voltage switching - can be connected in parallel with other electronic or mechanical switches
IPC: H03K17/96
Filed: 1974-04-19
Abstract: The electronic key is interchangeable with mechanical keys, and can be connected in series with a common impulse relay whose contact switches mains voltage on and off to or from the load. The idling current of each electronic key is negligibly small, so that the sum of all idling currents is smaller than the impulse relay holding current. It is also negligible in comparison with the current consumption of neon lamps. It comprises a rectifier bridge whose a.c. input is connected to the impulse relay, and d.c. output to the transistors connected in parallel. A second transistor emitter is connected through a resistor to the first transistor base, and through a capacitor and a rectifier bridge arm to a mains phase. The second transistor base is connected through a resistor to a contact plate.

Title: Pressure reducing valve of ventilation supply air outlet - has long throttling passage to reduce pressure without noise
IPC: F24F13/16
Filed: 1974-05-03
Abstract: The outlet has a chamber with side walls and internal adjustable vanes which can vary the direction of air discharge. Between this and the supply duct is a pressure reducing valve. It consists of two outer corrugated walls with a central fir tree shaped stem between them leaving two zig zag passages between the stem and the walls. A screw in a plate adjusts the axial position of the stem relative to the walls and therefore the width of the passages between them. The length of the passages is much greater than their width. The air pressure is reduced as the air passes through them but because of their length the reduction is gradual and therefore silent.

IPC: B65G60/00
Filed: 1974-06-27
Abstract: Device to build pile of pallets etc. each carrying a load. The pallets arrive on a conveyor (1) beneath the framework (4, 5, 17).

Title: Propulsion unit - for dynamic location of semi-submersible drilling platform, floats in a low draught transit position to facilitate inspection and repair
Inventor: CHEVALLIER JEAN
IPC: G05D1/02
Filed: 1974-09-26
Abstract: A propulsion unit for the dynamic location of a semi-submersible drilling platform with floats capable of submersion in a deep draught drilling position and of floating in a low draught transit position, comprises (a) a body designed to be fixed in and to close off an aperture cut in the upper part of one of the floats and thereby, to isolate a sealed compartment in the float (b) a support mounted on the body having an upper part designed to be extended above the float in such a way that is submerged in the drilling position and out of the water in the transit position (c) a propulsion element mounted in the upper part of the support member for exerting a thrust in a horizontal direction and (d) a transmission connected to the propulsion element and traversing the support members to extend into the sealed compartment. Advantageously, the transmission is connected to the output shaft of a motor so suspended from the body as to be situated in the compartment, which also contains a brake assembly associated with the output shaft. Since the propulsion element is out off the water in the transit position, the screw is readily inspected and in calm weather maintenance or repairs can be carried out without divers. Screw noise causes much less disturbance to acoustic detectors fixed under the floats for detecting the relative position of platform and well head so that vertical drilling is possible.

IPC: G01N25/48
Filed: 1975-05-07
Abstract: In line measuring appts. of the heat of reaction is intended for controlling chemical, biochemical and biological reactors. It is partic. useful in the fermentation industries as it functions in a sterile manner with industrial substrates. As adapted to a fermenter, the device comprises a temp. probe which operates a regulator with an on-off switch applying current to a resistance; Excess heat is eliminated by a fluid passing through a coil. The quantity of heat eliminated is evaluated by measuring the temp. of the fluid at the inlet and the outlet of the reactor. The temp. difference is obtd. from the differential thermometer. The amt. of heat added to the system by the action of the regulator and the resistance is measured. The fermenter is provided with insulation. The various readings are fed into a digital computer, and the results are displayed. The appts. effects an overall measurement of the total activity of the reactor; it is reliable, robust and simple, it does not cause any disturbance in the running conditions. Glucose, solid cellulose and methanol can all be used as substrates.

Filed: 1975-05-21
Abstract: A probe (1) is filled with water liquid and it is closed by a capsule (2) which can be broken by the increase in volume of the water contained in the probe. The capsule breaks along the line of least resistance (6) which separates its central part (2B) from an embedded peripheral part (2A). The detector produces a signal when the central part has been broken. The signal appears on a warning light (7) which is actuated by the relaxation of a spring (9) attached to the central port (2B) of the capsule (2). The spring may b outside or inside the probe.

Title: Stamping designs in moulded panels - using damp fabric between stamp and panel to ensure good definition
IPC: B28B11/10
Filed: 1975-11-13
Abstract: The surface of mineral materials which are being moulded are stamped, and any tearing away or defects on the edges of the stamped design are avoided so that a perfect impression is obtd. The surface of the pasty material is covered by a fine and moist fabric applied with the aid of a soft bush so the fabric adheres uniformly to the paste; the stamping die is then pressed onto the fabric and into the paste. When the stamping die is retracted, the fabric pref. remains on the moulded panel during predrying of the latter and is then removed. The penetration of the fabric into the paste, caused by the pressure of the stamping die, pref. results in pattern grooves with rounded sides. The fabric may also leave its impression on the stamped surface, providing a granular effect. The process is used in mfg. panels, plaques, tiles, table-tops etc., in cement, plaster, ceramics, porcelain or other moulded pastes, to obtain ornamental designs. Perfect impressions are obtd. with rounded sides providing a pleasing and artistic appearance.

Title: Clock signal generator for signal processing circuit - has controlled signal phase lag, using two frequency divider counters
Inventor: SASSOON ROGER
IPC: G06F1/06
Filed: 1976-08-30
Abstract: The clock signal generator supplies clock signals with a controlled phase lag, for use in a signal processing circuit, to compensate introduced phase errors. It employs two frequency divider counters, each supplied with the clock frequency signal and each supplying an output frequency which is a given fraction of the clock frequency. The second counter has secondary inputs for displaying a count value and a position control input for the count value displayed. A logic circuit coupled to the counters responds to the first counter exceeding a given count value, to control the position of the second conter to the value displayed, the latter controlling the phase lag between the two counter outputs, supplied to respective outputs of the clock signal generator.
