Title: Memory command circuit with transistor - includes several entry coils and erase coils and has reading coil controlling transistor
IPC: G11C11/06
Filed: 1975-02-28
Abstract: The memory has an element (2) adjacent to a reading coil (1) and a series of entering coils (4 to 7). The reading coil (1) is connected between the base and emitter of a transmitter (TR) and the emitter is also connected is earth. The collector of the transistor is connected to the positive pole of a DC source via two parallel circuits.

Title: Sliding telescopic railway wagon cover lock - has rotatable bar with sprung stop block to hold catch
IPC: B61D39/00
Filed: 1975-03-19
Abstract: The locking/unlocking mechanism is for use on railway wagons with telescopic sliding covers, and allows the sections of the cover to be immobilised both in the closed (or fully extended) position, and in the open position.

Title: Ultrafiltration control for artificial kidney - uses take off from membrane circuit to colorimeter to indicate acceptable blood transfer level
Inventor: SAUSSE ANDRE
IPC: A61M1/16
Filed: 1976-03-15
Abstract: The artificial kidney machine has an ultrafiltration control to indicate that the blood transfer level is acceptable. The dialysis fluid is passed alternately into one of two spheres a membrane acting as a pumping element to expel waste fluid. The new fluid passes through a degasser and into the filtration chamber.

Title: Adjusting resistance values by surface reaction - e.g. oxidn. of resistive metal, without thinning the substrate
Inventor: SOTA RAPHAEL PEREZ DE LA
IPC: H01C17/26

Abstract: Thin film resistances deposited on an insulating substrate are thermally adjusted by exposing them to a neutral gas atmosphere contg. in a small proportion a mixt. of gases capable of reacting chemically with the material of the resistive layers, the temp. being maintained constant during the reaction. Specifically the thin films are of beta-Ta the proportion of reactive gas is only a few ppm. and the reaction temp. 400-500 degrees C, the gases being oxidising in nature. The method adjusts the resistance by addition of material rather than local removal as with etching methods, thus there is no risk of making the material fragile.

Patent FR-2362514-A1 (FR)
IPC: H02M7/757
Filed: 1977-03-25
Abstract: The power supply device has a four-voltage selection device (B) as well as at least one set consisting of rectifier (C) and one current inverter (E) and two transformers (G, F), the frequency-independent loads being connected to one of the above and the frequency-dependent loads, for example, refrigerating units with motors (M) which are dependent on the frequency of the speed of rotation are connected to the other. Given direct current supply, the two transformers (G, F) are fed via the current inverter, given alternating current supply, the transformer for the frequency-independent loads is fed directly and the other transformer is fed via the rectifier (C) and the current inverter (E). The transformers are provided with different input terminals so that, depending on the supply voltage available, the supply line is connected in such a way that, irrespective of the supply voltage, the same load voltage is always available at the output. A rectifier (H) is also provided for the direct current loads at the output of the first transformer (G). Devices of this kind can be used in trains in which the bus line can have four different voltages, that is to say for example 1500 V= and 3000 V= as well as 1000 V SIMILAR (16 2/3 Hz) and 1500 V SIMILAR (50 Hz). In comparison with previous devices, this arrangement provides the advantage that it results in a substantial simplification of the feed line, and thus in a reduction of the weight and of course also a lowering of costs.
