Abstract: The device is used to support components (2,3...4), e.g. printed circuits boards, in a stack in such a way that the top of the stack stays at a constant level, corresp., for example, to the input or output of a machine fitted with a conveyor belt. The device comprises an input or output tray (1) and a system to adjust its height as a function of the load formed by the components placed on the tray (1). The height adjusting system contains a float (5) connected to the tray (1) and a container (7) filled with a liq. (6) which supports the tray (1). Detectors compare the actual level of the stack of components with the wanted level in order to vary the amount of liq. (6) in the container (7).
Patent FR-2506048-A1 (FR)
IPC: G07F7/08
Filed: 1981-05-12
Abstract: The indentification system consists of a key comprising a passive memory area (10) and a shift register (9) and a lock which can be coupled with the key. The lock is capable of supplying a set number of pulses causing the code contained in the memory (10) to be loaded into the register (9). The register (9) is subdivided into a certain number of elements linked together but loaded independently. This loading is carried out successively by the multiplexer (111). Transmission of an incorrect number of loading pulses leads, through connection (113), to a modification of the contents of the shift register (9).

Patent FR-2494885-A1 (FR)
Inventor: UMEDA HIROYUKI
IPC: G11B25/06
Filed: 1981-11-23
Abstract: The tape cassette has a supply tape reel and a pick-up tape reel. After loading the tape cassette into a recording and/or playback machine, a drive shaft engages from below in the supply tape reel and rotates it centrally. The pick-up tape reel is mounted on a fixed shaft and is driven eccentrically, by a rotation-transferring gearwheel engaging through a window formed in a side wall of the cassette housing and meshing with a toothing section on the outside of the lower flange of the pick-up tape reel. By this design, the diameter of the pick-up tape reel, and consequently the entire tape cassette, can be made considerably smaller. The then smaller tape cassette can be used both in a compact machine specially designed for it and in one of the previously customary standard machines of larger design, by in the latter case being placed in a tape cassette adapter of the shape and dimensions of a standard cassette.

Title: Pyruvic acid prepn. by oxidn. of 1,2-propane:diol - using platinum and a co-catalyst chosen from bismuth, lead, silver, tin, tellurium, indium or their derivs.
Inventor: COSTANTINI MICHEL
IPC: C07C51/235
Filed: 1982-05-28
Abstract: Preparation of pyruvic acid by oxidn. of 1,2-propanediol in aqueous medium, using molecular oxygen or an oxygen-containing gas, is effected in the presence of platinum and at at least one compound chosen from bismuth, lead, silver, tin, tellurium, indium and the derivs. of these metals, whilst maintaining the pH between 3 and 10. The pH is pref. controlled by the progressive addition of an alkaline agent during the oxidation. Pyruvic acid is a valuable intermediate in the preparation of aminoacids, such as L-tryptophane, L-cysteine and D-alanine. The present process provides a simple process for preparing pyruvic acid in excellent yields.
Patent FR-2524899-A1 (FR)
IPC: C09K3/22
Filed: 1982-06-25
Abstract: The invention relates to a dust-binding agent by which the dust on industrial roads with heavy traffic (cement factories, open-cast coal mines, quarries, ceramic industry) can be bound for a period of several weeks. The emulsion according to the invention consists of 10-32 % by volume of an emulsifiable mineral oil, 0.05-1.00 % by volume of carboxymethylcellulose, 0.1-0.8 % by volume of an ionic or non-ionic wetting agent, 8-49 % by volume of plasticiser, 39-55 % by volume of water and, if desired, up to 3 % by volume of water glass. The emulsion is sprayed onto the road area to be treated and has seeped away after 2-3 hours. The treated area is revived once per day by sprinkling with water, thus lengthening the duration of action. The treatment lowers the dust content of the air to less than 1 % of its original value, and, even after 12 weeks, it is only about 10 % of the original value.

Title: Framework system in particular for producing garden frames and tunnel greenhouses.
IPC: F16B5/06
Filed: 1982-07-09
Abstract: Framework system for producing garden frames, greenhouses or any shelter using films or nets. The invention concerns a method allowing the construction of garden frames or of any other type of small or large shelter using films or nets by using a universal basic profile capable of supporting the latter. This profile is in the shape of a "U" 1, inside of which a tube 2 is force fitted to jam the films or nets 6, one of the arms of the profile remains flexible while the bottom and the other arm are constituted from a double wall forming a box section into which can be inserted, as required, fish plates 3 used for butting or angles 4 allowing the production of frames. Clamps 5 serving as supports for tube arches can be fixed indifferently on two of the sides of the U-shaped profile, the length of the said tubes determining the height and volume of the object to be constructed. This construction system has very extensive application in the field of gardening and of the construction of light shelters for all uses.

Title: Feed device for a machine working on a web of material at rest, especially a press for cutting flat.
Inventor: ARMELIN GEORGES EDOUARD
IPC: B65H20/24
Filed: 1982-07-22
Abstract: The present invention relates to a feed device for a machine working on a web of material at rest, this web being continuously delivered upstream of the machine, by passing between a pair of delivery rollers rotating at a constant speed and forming, between this upstream pair of delivery rollers rotating at a constant speed and a pair of feed rollers disposed at the input of the machine and rotating intermittently, a reserve loop hanging freely. This device is characterised in that it comprises two lateral and vertical flanges 7 disposed on either side of the loop 3a, in the immediate vicinity of the latter, and an upper closure plate 8 extending between the two flanges 7, above the loop, so as to close off, in a regulatable manner, the upper orifice delimited between the upper portions of the two lateral and vertical flanges 7.
Patent FR-2517112-A1 (FR)
Inventor: BAUMRUKER HENRY
IPC: H01H50/44
Filed: 1982-09-13
Abstract: The invention relates to the connecting terminals of a coil such as those used in electrical switching apparatuses, for example contactors. The aim and object are on the one hand for the winding process not to be impeded by the coil connections and, on the other hand, for partial automation of the assembly of the connecting terminal to be made possible as a result of the structural configuration of the connecting terminal, with the connector technology itself also to be improved. The object is achieved in that a box terminal is placed on the connecting piece which is seated in the flange of the coil former, which box terminal is arranged in a terminal housing which is independent of the coil former. The connecting screw is held in a captive manner in the terminal housing. The terminal housing is pushed onto the connecting piece, which supports the barb, through a slot and in this way is connected thereto in a positively-locking and force-fitting manner. The front wall of the terminal housing is drawn back as far as the connecting piece and is used as protection against touching, while the rear wall is arranged between the connecting space and the coil winding and hence prevents insertion of the conductor through to the coil winding. Fields of application of the invention are electrical switching apparatuses such as contactors, relays, motor-protection switches and earth-leakage current protection switches.
