Patent FR-2321181-A1 (FR)
Title: Highly sensitive electromagnetic relay - uses attraction force generated in coil on yoke against spring force
IPC: H01H50/16
Filed: 1975-08-11
Abstract: The relay sensitivity ensures a low energy consumption. The relay consists of a stationary, U-shaped yoke and an armature, swinging between two end positions, these elements forming a magnetic circuit. A spring (2) tends to pull the armature from the yoke. The attraction force is generated in a coil (6), mounted on the yoke (1) through which flows direct current. The attraction force is generated against the force of the spring. Pref. a second coil (5) is mounted on the yoke, which reduces the magnetic flux, at least for a short period, under the control of a supplied switching pulse. A switching pulse may be also supplied to the first coil in the opposite direction to the direct current flow.

Title: Dry, solid, ruminant feed containing substantial amounts of lactose - suitable lactose source is ultrafiltrate milk serum from cheese and butter production
Inventor: THIVEND PIERRE
IPC: A23K10/28
Filed: 1975-09-12
Abstract: Dry, solid, ruminant feed contains >=40 wt. % (pref. 50-90 wt. %) of lactose. Previously lactose has only been used in small quantities in animal feeds (=10% in feeds and =40% in feed complements) as it was through larger quantities reduced the animal's liking for the feed, caused digestive troubles (diarrhea) and metabolic troubles (acidosis). Tests have shown that this untrue and ruminants can digest substantial quantities of lactose; the only precaution necessary is to gradually increase the amt. of lactose so that the animals digestive system can become accustomed to the new feed. A suitable source of lactose is from dairies and cheese factories which have no use for the milk serum after extn. of their prods. The main constituent of the milk serum is lactose and this may be recovered pref. by ultrafiltration of the skimmed milk and butter milk the dried prod. usually contg. 12-13% proteins, 10% mineral products and 70-75% of lactose. The feed may be presented as e.g. granules, meal, powder, condensed material, compacted material, tablets, as a licking block or nibbling stone etc.

Title: Purifying air contg. low impurity concns. - using an adsorbent strip contg. activated carbon fibres
IPC: B01D46/18
Filed: 1975-09-18
Abstract: Contaminated air is purified by unrolling an adsorbent strip contg. activated carbon fibres from a reel and rolling it up onto a second reel, while the air is passed through it between the reesl; hot gas is forced through the dirty strip to desorb and regenerate it. Pref., the second reel is permeable or perforated, to permit the gas to pass through it. The activated carbon fibres pref. possess a benzole adsorption, in the equilibrium state, >30%. A multilayer material, comprising activated carbon fibres in some layers, other fibres in other layers, may be used. The strip may follow a zigzag path in the air duct. Used esp. for removing low concns. of impurities, ranging from 0.1 to a few ppm, for air. Activated carbon fibres made be coking and activation of natural or synthetic fibres are used giving a much higher adsorption than that of conventional granular or powdered activated carbon.
Patent FR-2328949-A1 (FR)
Title: Piston dosing machine for pasty materials - esp. for dividing dough into small equal portions each sufficient for one loaf
IPC: G01F11/02
Filed: 1975-10-20
Abstract: Machine comprises a feed hopper supported by a frame which forms a box covering the different units. The cylindrical drum is mounted transversely to the flow of the dough and can oscillate between two positions by the action of a disc; this is connected to a crank rod. The drum has a cavity contg. a piston with its rod which has a pulley at its free end. In one of the positions, the opening of the cavity is opposite the hopper and can be filled with dough in the other position, the same opening is directed to the evacuating conveyor belt which receives the amt. of dough contained in the cavity. The disc mechanism, with its cams, regulates the amt. of dough drawn into the cavity by the piston, through the action of the cranked lever. The path of the piston can be adapted to the wt. of the individual portions to give the wt. of loaf required. It is not necessary to draw more dough into the cavity than is required; no dough is therefore left in the cavity to be mixed by the movements of the piston to the detriment of the bread.

Title: Coding and classifying system for passive memories - carries memories sequentially through coding, marking, classifying and testing stations
Inventor: BARRETEAU JACQUES CLAUDE
IPC: G06Q10/00
Filed: 1976-01-30
Abstract: The automatic coding and classifying system is used for programmable passive memories, each provided with a protective case. It comprises a distributor for sequentially transferring the memories from a reception station (1) to coding marking and classifying stations (2, 3, 4) under control of a processor.

Title: Electronic enuresis treatment unit - has stimulating impulses shaped similarly to human cardiac ones and actuated by urine sensor
IPC: A61N1/36
Filed: 1976-04-15
Abstract: The enuresis treatment equipment has detection electrodes normally is isolated from each other but mounted near the urethra and capable of being electrically connected by the urine, together with an electric generator applying stimuli to the patient when connection takes place. The stimulating impulses are shaped so that they approximate to that of the human cardiac impulses. This pulse shaper can be connected between the input and output of an impulse amplifier, having a controlled semi-conductor and a time-constant device. These render the amplifier non-conductive after a time lag. The urine detector can have a transistor whose collector-base path is connected to the electrodes, and which controls the supply to the generator.

Title: Shock absorber and anti-vibration mounting for engine - combines coil spring with wire braid core, and elastomeric pads to absorb larger shocks
IPC: F16F3/10
Filed: 1976-06-14
Abstract: A shock absorber and anti-vibration mounting for engines is provided with a base plate (1) which is fixed to the chassis of the vehicle.
