IPC: B03B4/02
Filed: 1974-02-20
Abstract: The grains of corn, rice or coffee beans are fed through a hopper and are allowed to fall onto the surface of the vibrating table which is divided by a step and which is driven by the rotating crank. A stream of air is blown across the table so that the lighter part of the mixture is blown on to the higher portion of the table whilst the heavier parts being less affected by the stream, fall to the lower portion of the table. The clean grain is delivered to the end of the vibrating table whilst the heavier foreign matter is delivered to the end.
Patent FR-2262233-A1 (FR)
Title: Maintenance of elastic range in tensioned cables - uses preloaded spring units with differing load extension thresholds
IPC: F16F1/44
Filed: 1974-02-22
Abstract: Two preloaded elastic systems are inserted into the cable run. One starts to elongate under a load which is greater than that required to fully elongate the other. The range of loads between full elongation of one system and the beginning of elongation of the other is the stabilisation range. A cylinder (1), filled with an elastomer (14) under pressure, which forces a piston (10) inwards, is joined to a cylinder (21) by a tube (36). On load, this piston (10) first moves out, compressing the elastomer until it reaches full travel, until the threshold load for compressing the second unit is reached. At higher loads, another piston (25) moves outwards, compressing an elastomer (34) until it too reaches full travel, and the cable is thus maintained in a state of elastic tension.
Patent FR-2263473-A1 (FR)
Title: Additional control for commercial or industrial heating system - switches heating off during periods building is unoccupied
IPC: G05D23/275
Filed: 1974-02-25
Abstract: A seven day clock can be set for the required combination of off periods during the week. The clock switching contacts energise and deenergise a relay with one normally open and one normally closed contact which is placed between the normal control circuit and the motorised valve worked by the control circuit. No modification is necessary to the normal control circuit which is retained. A frost thermostat re-energises the relay as necessary if the temperature falls during one of the off periods. A manual three position switch gives selection between clock control, heating off but under frost protection and heating permanently on. The control is particularly suitable for schools but is also applicable to other buildings.

The seal is formed by contact between two elastic surfaces of natural or synthetic material, typically between the flexible pipe inner surface and the outside of a bush on the sleeve. The external bush diameter can be such as to cause the end of the pipe to bell out. At the outlet end the clear internal diameter of the nut can be equal to or slightly greater than the pipe external diameter. The length of the bush can be such as to allow it to work in conjunction with the outlet end of the nut.
Patent FR-2283423-A1 (FR)
Title: Surface measuring machine for skins and leather - employing disc with peripheral sliding rods
IPC: G01B11/28
Filed: 1974-08-29
Abstract: Surface measuring machine, notable for sheet prodts. with regular or irregular edges, is partic. intended for skins and leather. It comprises a frame with a feed table; the matl. to be measured rests on the latter and is drawn through the machine by a conveyor belt, made from a number of nylon threads. A series of discs is carried on cross girders; each one turns freely on the hub, and is fitted with a number of rods which slide freely and radially in openings in the discs. A lower transverse support is provided by cylinders having a covering of rubber. The cylinders are driven and bear on the smaller rollers which support the matl. being measured. The rods project from their openings by gravity when there is no matl. between the rollers and the discs; if they meet a skin the rod is pushed back and cuts off a luminous ray emitted by the transmitter-receiver and produces a signal. The signals operate a memory counting system which records the surface areas. Greater precision and reliability are obtd. than hitherto as the turning and detection means are rigidly mounted to avoid any pivoting or other movement. The memory counting system assures that a complete count is made of all the signals from the different discs.

Title: Game with twenty eight dominoes - has no doubles and numbers from two to nine on dominoes
IPC: A63F9/20
Filed: 1975-01-14
Abstract: A game has 28 dominoes numbered from 2 to 9 with no doubles. The first player puts down a domino, the next player multiplies the two numbers. A domino must be played so that, when one of its numbers is added to the product of the first domino, the second number is wholly divisible in it. The game proceeds in this way for all players. If a domino 8-9 is played, the product is 8 X 9 = 72; the next player chooses a domino 3-5, placing the three against the previous domino to give 72 + 3 = 75. This is wholly divisible by 5.

Title: Cathodes for colour television tubes - with black, oxidised sleeves for rapid heat absorption when set is switched on
IPC: H01J9/04
Filed: 1975-01-29
Abstract: The process is for making a cathode for an electron tube, the cathode being a Ni base metal with a coating which emits electrons, the Ni being welded to a sleeve made of Ni-Cr alloy on which a holder is also welded. The Ni cathode and the holder are welded to the sleeve, after which the Cr in the sleeve is selectively oxidised to form a dark surface. The selective oxidn. pref. occurs in an atmos. of H2 and steam, using a temp. and partial steam pressure so that only the Cr is oxidised, and not the other metals, the pref. temp. being 500-1100 degrees C and the partial steam pressure being between -2.5 and 1.38, expressed as the logarithm of the press. in torr. Cathodes are used for television receiver tubes, esp. colour television tubes. Electricity used to heat the cathode is saved even when the receiver is not in use, i.e. a picture is rapidly obtd. (within 5 secs) when the set is switched on.

Title: Crimped polyester yarns based on ethylene terephthalate - with cross-sectional temp gradient set up in specif filaments
Inventor: REUFER CHRISTIAN
IPC: D01F6/62
Filed: 1975-03-19
Abstract: In the prodn. of a polyester yarn based on ethylene terephthalate, which, on detenting is capable of crimping, the pref. yarn has a double refractive index of 0.03-0.07, a capacity to shrink in boiling water of 40-80% and a crystallinity of is not >3%. Its matl. is for pref. a homopolymer or a copolymer with a large content of ethylene terephthalate units and a small content of units of a diol or an aromatic diacid derived elsewhere than from ethylene glycol or terephthalic acid. It is subjected to such a degree of stretching that after being stretching its elasticity is reduced to a value 15%. The stretching is localised at a point where the yarn shows a drop in temp. across its section, brought about by a brief passage of the yarn across a fixed, polished convexly curved surface maintained at a tem&. 2-30 degrees C below the m. pt. of the polymer. The process enables a satisfactory degree of crimp to be imparted at high speed. The crimps are fine and the elasticity of the yarn is good. There is no deformation of the section of the filaments and no trace of melting on their surfaces.
Patent FR-2265014-A1 (FR)
Title: Multiple shaft transmission - has driving and driven pinions located by discs of pitch circle diameter
IPC: F16H1/22
Filed: 1975-03-21
Abstract: Geared up driven shafts rotating at high speed are sometimes allowed to float radially, the centring of the shaft extremity being achieved by disposing at least three intermediate gears (5) equally around the pinion (4) on the shaft (1). A centring arrangement consists of hardened and ground thin discs (8, 9) mounted coaxially adjacent to their respective gears. The discs have a diameter equal to the pitch circle diameter of the gear teeth and therefore there is only rolling contact between them. Friction is therefore low and lubrication unnecessary. The external disc diameters are equal to the pitch circe of the gears and pinion.
