Patent FR-2350212-A1 (FR)
Title: Fine adjustment mechanism for drawing compasses - has spring loaded sleeve around adjusting screw inside sleeve with nut
IPC: B43L9/22
Filed: 1976-05-05
Abstract: A pair of draughtsman's compasses has a coarse adjustment mechanism on one leg and a fine adjustment mechanism on the other leg. An adjusting bar (3) through the two legs passes through a trunnion (6) secured to one leg (2) by a pin (7). This has a threaded end (9) passing through a plastic nut (11) embedded in the end of a knurled adjusting knob (12). As the knob is rotated, the nut (11) pulls the adjusting bar through the trunnion, thus pulling the two legs together. This action is assisted by a split sleeve (8) resting at one end against a flange (17) on the adjusting bar, with a shoulder (19) resting against a flange (15) around the inside of the knob (12). This carries a spring (16) which opposes the adjustment. Another nut 10) on the threaded part acts as a stop to limit the adjustment.

IPC: B08B9/02
Filed: 1976-08-26
Abstract: A method of disinfecting, deodorising, applying an insecticide or fungicide uses substances which are distributed only by means of vapourisation, instead of using a mechanical system such as a fan. One or more of the ingredients acts as a vector gas. The products used can be liquid or solid. They may be in liquid form, adsorbed by an inert substance. The liquid product may be conveyed by capillary action. The force of vaporisation can be controlled by modifying the compsn. of a mixt. of substances.

Title: Treatment of dyeing effluents - by oxygenation, electrolysis flocculation, separation and filtration, to yield a solvent suitable for further dyeing
IPC: C02F1/463
Filed: 1976-10-22
Abstract: An aq. solvent suitable for dye liquors for textiles is prepd. from effluent from previous dyeing processes. The effluent is collected, oxygenated and introduced into an electrolysis vat. An electric current is fed to a soluble metal anode which forms a flocculent metal hydroxide, suitable for adsorbing impurities contained in the effluent. The treated effluent is fed to a decantation filter which separates the flocculate from the liquid phase. The liquid phase is now ready to receive fresh dyes to effect a further dyeing process. The method provides an aq. solvent for improving dyeing quality. It avoids the wastage of used dye liquors, and provides a process and installation for dyeing textiles in closed circuit, without producing significant quantities of effluent.

Title: Plastics protective cover for outdoor plants - has parallel rows of slits with variable size top and bottom unperforated band
IPC: A01G13/04
Filed: 1976-10-29
Abstract: The sheeting is made of non-toxic plastic such as polythene, of suitable width and thickness of cut-off lengths. The sheeting has slits (3) pref. in parallel rows, in staggered formation. The size and distance between slits can vary. At each lengthwise edge of the strip of sheeting is a non-perforated band. For protecting plants outdoors, like tomatoes, the cut-offlength of sheeting is placed over the shaked (7) plant (8). If the sheeting is too high for the initially small plant, it can be tied round (9) at the top. The bottom of the sheeting (10) is anchored to the ground, by rolling the bottom, by placing earth on it, or by staking it. As the plant grows, the covering (11) is pushed upwards to leave a gap between it and the soild.

Patent FR-2333286-A1 (FR)
IPC: G04F3/00
Filed: 1976-11-24
Abstract: 1528700 Electronic timer DAINI SEIKOSHA KK 25 Nov 1976 [27 Nov 1975] 49227/76 Heading G3T An electronic timer particularly for games, comprises down-counters 13, 14, 15, Fig. 3, the counter 15 serving to memorize a 10 minute half-time rest period while counters 13, 14 memorize 40 min and 20 min periods respectively. A switch 32 is operable to select either the counter 13 for timing each half of a football match or the counter 14 for timing basketball, and accordingly a display portion 5, Fig. 1, is activated to show either a footballer or basketball player in action. A digital display of remaining time is given and an alarm generator 23 (e.g. a buzzer) is activated when the display shows 00.00. The counting sequences are controlled by a shift register 22. With switch 32 closed to select basketball counter 14, a switch 18 is momentarily closed at the start of a timing period thus providing a shift pulse so that output Q 2 of SR 22 becomes "1". The resulting output of AND 30 releases a reset on counter 14 which begins counting 1 Hz pulses from a frequency divider 11 fed by an oscillator circuit 10. At the end of the 20 min period, the counter 14 produces a signal which causes activation of the alarm and shifts SR 22 output to Q 3 . Thereby counter 14 is reset and the reset on counter 15 is released so that it begins to count the 10 min interval at the end of which counter 15 likewise produces a signal to shift SR 22. Thereupon counter 14 begins to time the second half of the game. The counting of any period can be temporarily interrupted by opening a switch 12.

Patent FR-2373979-A1 (FR)
Title: Casque de protection avec visiere
IPC: A42B3/00
Filed: 1976-12-20
Abstract: Cette invention concerne un dispositif de protection muni d'une visière en matière plastique. Cette visière est fixée de façon amovible mais résistante sur un support monté sur le dispositif. La visière présente une fente allongée dans laquelle est logée une came. Le lobe de cette came est légèrement plus long de la dimension transversale de la fente, de sorte que lors de la rotation de la came entre la position de dégagement et la position de blocage, il déforme légèrement la fente, celle-ci revenant sensiblement à sa dimension initiale lorsque le lobe de la came parvient dans la position de verrouillage. Cette came maintient ensuite la visière dans une condition tendue et la fente resserrée empêche la rotation de la came, de sorte que celle-ci demeure dans sa position de verrouillage. Une disposition de ce type est utilisable notamment pour la fixation des visières sur les casques de protection.

Title: Regulator for low power vehicle alternator - includes temp. sensor in stator to effect temp. control of rotor excitation current
IPC: H02H7/06
Filed: 1978-03-24
Abstract: The alternator and regulator includes a stator (1) and rotor (2) carrying the excitation coils. Induction coils (3) in the stator supply a diode bridge (3) connected between the output supply line (4) and earth. A thermistor (7) in the stator forms a temp. sensor. A control stage (8) compares the voltage (T) with a reference voltage (Tr) to control the excitation current accordingly. The voltage (Tr) is supplied by a selector (9) which receives a reference voltage (U1) and a voltage (U2) supplied by a temp. control stage receiving its information from the pickup (7). Excitation current is thus controlled as a function of the prevailing temp. in the stator.
