Patent FR-2050294-A1 (FR)
Title: Powdered product mfre by desiccating a - fluid
IPC: A23C1/04
Filed: 1969-07-18
Abstract: A fluid material is transformed into a powder by evaporating the liquid with hot air acting on the particles of the fluid projected by a turbine, the fluid is propelled through the turbine by air charged with fines coming from a previous phase of the treatment. The fluid material is supplied by a pump, the delivery tube of which opens in the lateral wall of a 'gun'. Hot air, charged with fines, coming from a cyclone, is delivered to the top of the gun which is connected at its lower end with a tube leading to the inlet of the turbine, the air disperses the fluid material and mixes with, and units, the fines in the channels of the turbine so that the resulting powder has a uniform grading with a minimum proportion of fines. The process can be used for the preparation of milk powder and cattle feeds.

Patent FR-2198323-A1 (FR)
IPC: H03K19/003
Filed: 1973-06-13
Abstract: A new circuit is provided for checking for errors caused by most but not all of the faults that might occur in a network of logic gates. One part of the checking circuits, called a "1 cover" produces an output that is designated C1, and includes selected prime implicants of the function, F, of the newtork being checked. Thus, if there is no fault in either the circuit being checked or in the 1 cover circuit, C1 = 1 implies that F = 1. A comparison circuit is provided to produce an error signifying output, E, for the condition C1 = 1 and F = 0.

Title: Spare wheel chain windlass - has underneath face to which wheel is bolted after lifting
IPC: B66D3/14
Filed: 1974-02-12
Abstract: The windlass is particularly for handling the spare wheel of a lorry, being mounted on one of the lengthwise members of the chassis. Underneath it has a face to which the wheel is bolted after it has been raised by the windlass. The chain sprocket can be worm-driven from a shaft on whose end the lorry starting handle fits, and there can be a pivoting support on the end of the chain engaging under the wheel disc, while the free chain end falls under gravity as the wheel is being raised, and vice versa. The support can be secured to the face of the windlass housing, so as to clasp the wheel between them. The housing can accommodate the complete mechanism, the chain emerging from it via cruciform and square openings for the support and free ends respectively.

Patent FR-2242828-A1 (FR)
Title: Colour TV line and colour signal stabiliser - compares sub-carrier frequencies with line frequency to give feedback
IPC: H04N9/45
Filed: 1974-08-28
Abstract: As the sequential colour/memory television system has a frequency modulated chrominance sub-carrier, it is necessary to provide good stability of the sub-carrier quiescent frequencies to avoid changes of tube colours. The stabiliser is based on coupling between the line frequency and the two quiescent frequencies of the chrominance sub-carrier. Two oscillators (1), (2) generate signals for the lowest (fob) and the other (for) of the quiescent frequencies. These two signals are applied to mixers (13, 14), filters (15, 16), demultipliers (16, 19) and phase comparators (4, 20) to give regulated voltages dependent on the deviations from the line frequency (fH). Stabilised frequencies are then obtained at the outputs (7, 11) of the oscillators.
Patent FR-2248067-A1 (FR)
IPC: B01J19/32
Filed: 1974-10-17
Abstract: Disclosed is a multi-functional grid structure for use in a vapor-liquid contact apparatus which includes a plurality of layers of relatively thin ribs. Some layers of ribs are flange-free and act as liquid distributors. Some layers of ribs include ribs with flanges and act as vapor-liquid contact devices. Some layers of ribs may have ribs with flanges having upturned edges which form channels, and such layers act as liquid collectors. A single grid structure performing these multiple functions normally requires only a single support structure, thereby saving on tower structure and cost.

The fibres have better moisture absorption than known polyamides, e.g. nylon 6. Other properites of the fibre are not affected by the poly(dioxa-arylamide). Fibres obtd. by spinning or by melt-spinning the copolymers are claimed. The copolymer can be used for prods. other than fibres.
Patent FR-2253262-A1 (FR)
Title: Contacting device with armature held by magnetic force - engaged by control element and carrying contact spring
IPC: H01H37/66
Filed: 1974-11-25
Abstract: The contact spring is parallel to the armature and can be deflected in a limited way. It can be used for space thermostats. The one single contact spring between armatures can move between two stops and makes contacts with two fixed contacts on both its sides. It is adjusted to its neutral position between the two stops consisting of the armature itself and the underside of a distance adjustment screw. A position adjustment screw i the armature presses against the contact spring by the end projecting from the armature. The danger of short circuiting during the switching over period between the main and opposition working contact is avoided by the accurately adjusted yet simple co instruction.

Title: Electrically driven out-of-balance vibrator - can remotely select one of two levels of out-of-balance forces
IPC: B06B1/16
Filed: 1975-02-17
Abstract: The electric motor has two cages mounted side by side on the shaft. The cage is rigidly fixed to the shaft but the cage, which is unbalanced, is attached to the shaft by a spring-loaded bolt so that it can be held in one of two positions, approximately 90 deg. apart. The polar moment of inertia of the cage is much smaller than the moment of inertia of the cage together with its shaft and flywheel. Thus when the motor is started the cage is rotated relative to the shaft to one of its extreme positions. To change the position of the cage the direction of rotation is reversed.

Title: Fastener for ear muffs on worker's helmet - eases brief displacement of muffs for hearing purposes
IPC: A42B3/16
Filed: 1975-05-13
Abstract: The sides of the ear muff are attached to the two ends of a piece of thick wire whose middle is folded into a narrow loop with parallel sides, round which a broad strap (8) is fastened for stiffness. The loop is attached to the hat by a double-ended stud whose parts are joined with a quick-release fastening. Thus the ear muffs can easily be removed from the hat when this is desired. When attached to it, they turn easily on their studs (2, 2', 2"), so that the wearer can displace them slightly when he needs to hear and replace them afterwards without difficulty.

Title: Extraction method for steel rod ground anchors - rupture zone in rod adjacent to anchor block is formed by heating
IPC: E02D5/76
Filed: 1975-06-27
Abstract: A steel anchorage rod (2, 6) between sheet pile walls or other retaining walls and embedded concrete anchor blocks (4), is simply removed after useful life, by forming a rupture zone in the tie rod adjacent to the anchor block, so that a pull applied to the rod causes rupture at this point and rod extraction. Applicable to the type of tie (2) sheat ed in a plastic tube (3) between the wall and the anchor block (4), the process uses the application of heat to diminuish the steel strength characteristics. A tie coupling sleeve (7) containing thermite powder (8) can be used, ignited via cable (10) and fuse (9).
