Title: Plaster panels mfr. - by spreading dry materials onto a conveyor belt fitted with water jets, filter and vacuum-suction
IPC: C04B40/00
Filed: 1975-09-05
Abstract: Process for mfg. plaster panels, where the surface of a conveyor belt is fed with plaster, fibres or other fillers, or a mixt. of these materials, in one or more superimposed layers, plus water for setting. When the plaster is spread out its temp. is 1-140 degrees C and the layer(s) are dry, i.e. only the residual water of crystallisation in the plaster is present; the layer(s) are shaped and/or compressed, and water is then added across the entire width for setting; and a pressure difference is established between the surfaces of the panel to ensure the distribution of the water and to remove the excess. The plaster is pref. at 10-100 degrees C and the panel 5-100mm thick; the pref. appts. is included in twenty claims. Avoids the use of large amts. of energy involved in removing excess water, or the use of refrigeration so the water can be added as ice, i.e. this process is very economic.

Title: Combined water and electrical convector heater - has heating resistance above water heater body in common housing
Inventor: GOUYOU-BEAUCHAMPS JACQUES
IPC: F24H3/00
Filed: 1975-09-16
Abstract: The mixed water and electrical convertor heater is particularly for supply with lukewarm water by a heat pump, having a water heater body and a supplementary electrical heater body in the same housing. The water heater body is supplied with warm water from outside, and has no electrical resistance in the water passage or in contact with the water tube or its fins. The supplementary electrical resistance is of the conventional type, mounted in the convertor housing directly above the water heater body, but having no contact with it. The fins of the two heater bodies can be in the same vertical planes, or offset from each other. The resistance can be controlled by a thermostat reacting to ambient air temperature, and insulated from the chamber through which the hot gases flow.

Title: Magnetic tape data protection system - uses ribbed ring which engages tape protection slot in spool
Inventor: SORGE ALAIN
IPC: G11B23/28
Filed: 1976-03-18
Abstract: The magnetic tape protection system is incorporated in the base of the spool. It permits protection of the data on the tape by the to and fro movement of donal ring (4) in a slot. The ring (4) is fixed to ribs (2) which pass through the spool. These ribs are fixed to a ring (1) positioned in a slot at the base of the spool (3). Each rib (2) has a spring (6) fixed on it. A second removable ring (5) is screwed over the donal ring (4) into the spool (3). Fitting of this second ring (5) assures a pressure onto the donal ring ribs (2). This pressure compreses the springs (6) and displaces the donal ring (4) to the edge of the slot.

Title: Bitumen additive dosage machine - corrects for varying density of material detects belt tension change and controls speed
IPC: G01G11/12
Filed: 1976-05-24
Abstract: A machine for the continuous weighing out of materials is esp. for the addition of gravel type materials to binumenous materials for road surfaces. A hopper for the gravel type material is supported over a conveyor belt in contact with the lower part of the hopper through which a lateral opening feeds a constant flow of material to the belt at a rate controlled by varying the aperture. A frame is supported on pivots behind the hopper to support the guide rollers of that end of the belt. If the weight deposited on the best baries, e.g. by varying density of the hopper material, the different loading of the best is detected, and the pivoted roller supports deflected to correct the drive of the belt to make a correction.

Title: Automatic transfer of unit loads to or from processing carrier - esp. food and pharmaceutical packs for sterilising, cooking etc.
IPC: B65G47/74
Filed: 1976-08-02
Abstract: Process transfer unit loads into or out of a succession of mobile, tubular, pref. cylindrical, open-ended carriers used to contain the loads during processing operations. At each transfer station, the carriers are disposed with their axes horizontal and evenly spaced around a pitch circle, pref. in pockets in a horizontal cylindrical drum rotatable about its axis. To load a carrier, a unit load is placed on a scoop blade which is then advanced axially into a carrier as it starts to move through a transfer station. Carrier and scoop are rotated simultaneously about the axis of the pitch circle, so that the scoop is inverted through 180 degrees to dump the unit load into the carrier. The scoop is retracted and the loaded carrier leaves the transfer stations. Used for loading and discharging carriers which pass through processing operations. Prod. may be food or drink for sterilising, pasteurising etc. as well as pharmaceutical prod. and loaves of bread for baking.

Title: Modulation for HF swept beams - employs amplitude and phase modulation and sequential switching to fixed array
IPC: H01Q3/24
Filed: 1976-12-21
Abstract: Modulation system for the power supplied to phase fed antennae systems, providing a narrow continuous swept beam at micro wave frequencies. The antennae array to be fed has, for example, 16 elements fed sequentially by four digital type phase modulators spaced at 22 deg. 30'. Each such modulator feeds an amplitude modulator which is coupled into four individual antennae elements distributed through the sixteen element array by a single switch. The four parallel modulation chains are fed from a common RF power source, the modulation providing an output which is determined by calculation of distributed current to produce the beam required, the conjugate of the current and amplitude limitation.

Title: Rapid thermal curing of polymeric compsns. - by contacting with a high velocity hot gas stream under elevated pressure
Inventor: GREENHALGH MILTON SHARPLES
IPC: H01B3/14
Filed: 1977-09-29
Abstract: A polymeric compsn. is cured by contacting its surface with a stream of gas heated to >=450 (600-1000) degrees F (or >= 425 degrees F in the case of a halogen-contg. polymer), flowing at >=3000(6000-10000)ft./min while under a pressure of >=45(75-200)psi., in an elongated chamber. The method is applicable to the curing of an elongated electrical conductor insulating covering. The heated gas effectively sweeps away all intermediate air or gas molecules between the stream and compsn. surface, which can obstruct efficient heat transfer. The curing rate obtd. is at least several times faster than achieved with satd. steam, and the high pressure and moisture penetration handicaps of steam are avoided. The appts. required is simple and inexpensive.

Title: Vehicle steering transmission between shaft and rotary component - has friction clutch and locking bar securing component in housing
IPC: F16D1/12
Filed: 1977-10-05
Abstract: The mechanism transmits movement between a shaft and a rotary component, these being in a set angular position in relation to each other, to allow accurate angular setting. A friction clutch (8-10) transmits torque between the shaft (1) and a gear (7), the torque capacity of the clutch being higher than that normally transmitted so that normally there is a solid coupling between component and shaft. A locking device (19-21) secures the component in a particular angular position, a recess in the component being in line with a hole in the housing when the component is in this position to allow insertion of a locking bar. When torque in excess of that which the clutch can transmit is applied to the shaft, the latter can be turned in relation to the component, to adjust the relative angular setting.

Title: Canard for supersonic aircraft - has stabiliser disconnected from flying controls to facilitate transition to supersonic speed
Inventor: POISSON-QUINTON PHILIPPE
IPC: B64C5/10
Filed: 1977-10-17
Abstract: The forward stabiliser or canard (2) of a supersonic aircraft is linked to the aircraft flying controls to improve control of the aircraft during landing and take-off.
