Title: Sealing ring of the thermoplastic cap of a pneumatic tyre valve - held in place by burring the thermoplastic under heat
IPC: B60C29/06
Filed: 1975-12-11
Abstract: The thermoplastic cap is moulded with a small hollow tube projecting inwards centrally from its closed end. The sealing ring is placed in position round this tube, whose edges are then spread by heating until they hold the sealing ring in place, without encroaching on the part needed for the sealing. The tool applying the heat allows the heat intensity to be varied. The sealing ring is held more securely in place at the bottom of the valve cap.

Title: Manufacturing process for brushes - uses rectangular frame with bristles arranged above sliding plate with ferrules under plate
IPC: A46D1/08
Filed: 1975-12-19
Abstract: A manufacturing process for brushes consists of arranging the bristles (7) on a sliding plate (4) in a frame (3) with the ferrules (6) underneath. The bristles are pressed together with the same density as in the final brush and the ferrules are arranged one against the other with their upper edge just under the plate. The bristles are dropped into the ferrules when the plate is removed by making the bristles vibrate. The homogenous density of the bristles on the plate is also obtained by vibration. When the bristles are in the ferrule they are treated in the normal way to complete the brush.

Title: Single channel data interchange equipment - has central transceiver with data transfer to secondary stations (SF 31.8.77)
Inventor: SARRAND PIERRE
IPC: H04L12/24
Filed: 1975-12-31
Abstract: The data interchange equipment has several transmitting-receiving stations interconnected by one channel. The data interchange can be initiated by any one of the stations through a central station which is not apparent to the initiating station. The equipment has three stations (ST1, ST2, ST3) interconnected by a channel (10). Each station (ST1, ST2, ST3) has a data processing transmitting unit (DPC1, DPC2, DPC3) and an adaptor unit (FEL1, FEL2, FEL3). The processing units (DPC1, DPC2, DPC3) have pre-recorded instructions (I1, I2, I3) and have memory stores (M1, M2, M3). Peripherals (20, 30) are also used. To initiate a station (ST2), a module (MI) of the station initiates the instructions (I2) in the processing unit (DPC2) and at the end of the instructions sends a message identifying the central station (ST3) and requesting initiation to all stations through the channel (10). The central station (ST3) consults its memory store (M3) and sends any data to the initiating station (ST2).

Title: Inflatable air supported resilient sheet structure - comprises units arranged as circular sheet with compensating converging cables
IPC: E04H15/22
Filed: 1976-01-19
Abstract: The resilient material which can be inflated under slight superpressure to serve as interior spaces or room. It is made up from ground-anchored interconnected resilient sheets which together provide a hollow interior space. Before inflation takes place the whole assembly is arranged in a flat continuous circular sheet (1) with a circle periphery (2) larger than that of the inflated unit. Inflation is effected simultaneously with retraction of the circular periphery on the ground and raising of the central area, without any pronounced expansion of the sheet material. Following inflation, the sheet surface expansion differential, resulting in the formation of rounded areas, is compensated by cables (3) with one end anchored to the ground while their other ends are united with a common central connecting member.

Title: Ferroalloy mfr., esp. ferrosilicon - where exhaust gas dust is collected, pelletised and returned to mfg. process
IPC: C22B7/02
Filed: 1976-01-23
Abstract: Ferroalloys are made from fine prim. materials which are conditioned and agglomerated to make pellets or extruded using a min. amt. of binder. The initial mixt. pref. contains: (a) fine dust reclaimed from purification plant, and possessing pronounced adhesive and hydraulic properties, thus permitting a redn. in the amt. of binder required, and reducing the wear of tools employed to make the agglomerate. The mixt. also contains (b) coal dust, pref. added in a stoichiometric amt. where the fine coal dust improves the redn. of oxides in the mixt.; (c) fine iron ore to provide iron in the ferroalloy; (d) water to aid agglomeration. The agglomerate may form part or all of the charge in an electric- or shaft-furnace used to mfr. ferroalloys, esp. a cupola using a hot blast enriched with oxygen to mfr. carburised ferrosilicon. In, for example, the mfr. of Fe-Si, dust is obtd. in the exhaust gas, and must be collected to prevent environmental pollution. The dust is made into pellets and re-used in mfg. Fe-Si, thus reducing the overall cost of the process.

The wheel rim can be split, with the centre wall of the tyre clamped between its sections to seal each chamber from each other and from atmosphere.
Patent FR-2349432-A1 (FR)
Title: A tubular mesh extrusion die with a pressure face opposing the cutter - to eliminate melt deformation and blind mesh
IPC: B29C48/10
Filed: 1976-04-29
Abstract: Extruder head incorporates an eccentric toothed disc or collar coincident with an annular extrusion die to produce perforated tubing or netting. A toothed element bears against a solid collar or core respectively where the teeth intersect the flow path. The nip ensures that the melt path is perforated and the melt is unable to deform over the end of the tooth and thus produce blind interstices. The core plate or collar may have a smooth or ribbed annular profile to butt or mesh with the cutter teeth.

Title: Domestic central heating and hot water system - has solar and waste heat recover units forming main heat source with make=up heat obtained from combustion installation
Inventor: GIRARD EDMOND
IPC: F24D11/02
Filed: 1977-06-10
Abstract: The central heating and hot water system has a fuel-burning heat source providing make-up heat for the water before it flows through radiators or is used for washing etc. The main heat source is formed by a number of heat -recovery units, notably a roof-mounted solar heating panel and a heat exchanger mounted in the stale air discharge conduit from the building. The refrigerating liquid of a heat pump heats the water before returning to an evaporator where it absorbs the excess calories from the recovery units. These units also include a heat exchanger in the flue of the fuel-burning source, and are connected in series in a single hydraulic circuit incorporating a tank which the heat pump evaporator is immersed in. The refrigerating liquid is cooled successively in a first heat exchanger immersed in a washing water tank, and a second heat exchanger acting as a condenser immersed in the heating water tank.
