Title: System for ensuring uniform rate of turning of locomotive wheels - has logic circuit with counter for controlling wheel speeds
Inventor: KUZNETSOV B G
IPC: B60L3/10
Filed: 1975-06-10
Abstract: The acceleration protection arrangement is used especially in locomotives in order to ensure uniform rotating speeds on all locomotive wheels. Different speeds of the wheels are caused by different loading of wheel sets. The uniformity of the wheel speeds increases the tractive force. The control system covers a wide range of speeds and it ensures maximum wheel and rail adherence. Each wheel set has a system for generating pulses proportional to the rotating speed. This system is coupled to the counting circuit by means of a multiplexing circuit for separating pulse generator signals. Each counting circuit has only one pulse counter and the time multiplexing circuit has at least four inputs. The logic circuit of the system is coupled to a speed regulator of the wheel set drives.

Patent FR-2338010-A1 (FR)
IPC: A47B13/06
Filed: 1976-12-02
Abstract: The tubular legs (16) engage from below in the corner parts (12) of the table top (10). In the plane of the table top, said tubular legs are either covered by a cap (21) or provided with a coupling part. Said coupling part can serve for receiving a plugging-on part for the purpose of extending the table to form a structure. An aperture (22) can be provided in said cap for the passage of electric leads (20) leading from one tubular leg. Particularly the possibility of extension to form a structure and the presence of compartments in the individual table or structure in order to receive equipment (telephone, lamp, calculator or dictaphone, etc.), to which the leads (20) are conducted, can be considered to be a great advantage.
Patent FR-2343238-A1 (FR)
IPC: B01L3/00
Filed: 1976-12-06
Abstract: A multichamber cuvette for maintaining in independent and separate condition at least two reactants, one of which may be a sample, until such time that it is desired to mix them for reaction with each other for photometric analysis in the cuvette. At least one of the chambers has a pair of optical quality windows aligned with one another for analysis of the then liquid contents extending between the windows. The cuvette body is of upright construction, defining at least two such chambers laterally of one another, open at the top for filling separately or simultaneously, and interconnected adjacent their lower extremities by a passageway of inverted U shape. The passageway is of an effective height exceeding the highest filling level of each chamber by a distance at least as great as any capillary rise in the passageway beyond such level of the particular liquid in that chamber. Accidental mixing of the chamber contents is prevented by entrapment of air in the passageway by the respective liquids in the chambers and partially filling the legs of the passageway. Mixing through the passageway is effected by the forced flow of fluids therethrough from one chamber to the other while one of the chambers is vented to the atmosphere at the top. The passageway is so configured and also dimensioned in cross section as to allow for the free flow of liquid between the chambers.

Title: Contact lens handling suction tool - is tube with flared mouth and pouch at opposite ends deforming to create vacuum
IPC: A61F9/00
Filed: 1976-12-21
Abstract: The tool to pick-up and transfer a contact lens uses the suction cup principle. It has a slender elongated tubular body (2) with a head (3) of trumpet mouth form, and an elastic pouch (5) mounted over the rear (6). Air is expelled by pressing the pouch (5) to create a vacuum at the head (3). The head (3) is then applied to the lense, the pouch (5) released, and the lens picked up by suction. The head (3) may be formed by a tapered increase in the diameter, or the tube (7) may be of trumpet-mouth, bell, or cup form and may have supple lips (11). Alternatively the walls (10) of the head may progressively diminish to a knife edge (11), and the internal bottom surface (9) of the head may be at right angles to the air outlet (4). Further alternative forms may include an air-permeable pad filling to the head (3), and the pouch (5), may be incorporated in the tube to be deformed by a lever or a piston.

Title: Sludge collection filter stocking for sedimentation plant - is cut off in easily handled sections filled with sludge for disposal
IPC: C02F11/128
Filed: 1977-03-09
Abstract: Sludge settles in textile filter stockings suspended from the base of a decanting tank, as described in 75.22296. Each stocking is made so that it is initially, very much longer than the suspended length required in operation. The surplus length is longitudinally folded, partic. concertina fashion, at the top, open end of the stocking where it is temporarily retained by a clamping collar. When sufficient sludge has been collected in the bottom section of the stocking, liq. is drained from the stocking above the sludge and the stocking double-ligatured just above the bottom section. The bottom section is then detached by cutting off between ligatures. The detached sludge pocket is removed and the stocking longitudinally unfolded sufficiently to restore its original suspended length. The liq. is pref. drained by inserting a hollow needle into the stocking above the sludge pocket section. Drained liq. is pref. recycled to the decanting tank. Use for sludge collection from the treatment of effluent from industries such as electroplating, pickling and other surface treatment of metals, painting etc. Sludge can be conveniently handled and dried without removal from the detached pocket. Stockings are restored to 'as-new' efficiency without removal and renewal.

Title: System confirming authenticity of identity card holder - reads data from card and processes secret data fed in from holder to produce signal if true owner has card
IPC: G07F7/10
Filed: 1977-03-11
Abstract: The card carries mechanically readable data, and the test is in an on-line system with a central computer and at least one distant terminal with a card reading device and a keyboard. Data are read from the card. A first signal is generated, representing the data read from the card. A second signal is generated by the keyboard representing secret data fed by the card holder. The correct data are known only to the rightful owner. The second signal is converted in two parts, the first signal is converted into a first converted signal without any logical connection with the first signal. The converted first signal is compared at the distant terminal with the first signal part, and if the result is positive the second signal part is transmitted to the central computer which compares it with a reference signal. If the result is positive, a signal is generated which declares the holder to be the rightful owner.

Title: Pulse-operated magnetic switching system - has coil reacting with two bar magnets operating switch wiper blade
IPC: H01H36/00
Filed: 1977-04-01
Abstract: A reversible or two pole electrical switch (1) is driven from a solenoid. The switch is intended to overcome some of the problems associated with the fragility and sealed nature of reed - relay switches. The switch electrodes and associated mechanism can be dismantled for replacement and adjustment at will. The operation is based on the use of two bar magnets positioned in line with respect to each other and in opposition magnetically, i.e. pole to pole. The lower magnet which drives the wiper of the switch contacts has a surrounding centre-tapped coil which by virtue of the current direction can cause switch closure through two positions.

Title: Decaffeination of green coffee - by aq. extraction, drying, and extraction with organic liquid
Inventor: HUDAK STEPHEN FRANCIS
IPC: A23F5/20
Filed: 1977-05-13
Abstract: Green coffee is decaffeinated by extracting the coffee with an aq. liquid, drying the liq. and extracting the dried solids with a liq. organic solvent. Pref. solvents are methyl, ethyl and propyl alcohols. After sepn., the solvent may be processed to recover noncaffein solids which are then combined with the dried coffee solubles (e.g., by cooling to ppte. coffee solubles and then extracting with a solvent for caffeine). The solvent and caffeine extractant may be the same. The aq. liquid may be (a) water and the decaffeinated dried dolids are reconstituted with water and adsorbed on water extracted green coffee or (b) a caffeine deficient soln. of green coffee solubles and the decaffeinated dried solids are reconstituted with water and the resulting soln. is used to extract caffeine from green coffee. Eliminates the need for the use of halogenated solvents. The aq. soln. is dried, allowing the use of water-miscib-solvents.
