Title: Water-filled polyester resins - for totally non-inflammable plastics materials, esp. for building applications
IPC: C08K3/30
Filed: 1973-09-19
Abstract: A totally non-inflammable plastics material which is a polyester resin highly charged with water is prepg. using a halide/alkali emulsifying system at ambient temp. and press. with stirring addn. The materials claimed are partic. applicable to the building industry e.g. for the manufacture of building panels. Application of a flame to these materials produces charring with no immediately detectable gas-evolution and no flame. The use of a water-filler enables redn. of the polyester concn. to 10-30% of the total to be achieved, giving a lighter material. Because a low exotherm is developed in curing, water loss is very low and so, therefire is shrinkage. Age-yellowing is observed at a minimum.

Title: Tyre vulcaniser mould assembly - having tread moulds actuated by adjustable links
IPC: B29D30/06
Filed: 1973-10-23
Abstract: A tyre vulcanising mould has a lower stationary mould, an upper marable mould carried relatively movably from a bolster plate, outer ring walls suspended from the periphery of the bolster plate, links connecting the walls to tread moulds, means to adjust the height of the connection between the links and the walls, horizontal guide surfaces on the upper mould for each tread mould, and means for relatively maring the upper mould and the bolster plate. In use radial closing and opening movement of the tread mould is obtained by relatively moving the bolster plate and the upper mould to cause the ring walls to move vertically and actuate the links, this in turn causing the tread moulds to move along the horizontal guide surfaces. By adjusting the position of the points of connection of the ring walls and the links, different movements of the tread moulds are obtained and adjustments to remove burr forming gaps can be made.

Title: Felt produced by depositing fibres on conveyor - from a chamber whose volume is adjustable to vary fibre density and orientation
IPC: D04H1/72
Filed: 1974-06-14
Abstract: Fibres are fed to low open upper end of a chamber arranged above a porous conveyor whereby the fibres pass from the open lower end of the chamber (pref. under the action of a suction applied beneath the conveyor) and are deposited randomly on the conveyor to form e.g. a felt, paper, cardboard etc. One of the sides of the chamber is closed by an adjustable wall which is pref. pivotally mounted at its upper end and which is movable to vary the volume of the chamber and so vary the density and orientation of the fibres on the conveyor. Pref. the adjustable wall has a side wall at each end, and these walls can be sepd. by e.g. a cam mechanism so that they engage the side walls of the chamber to maintain the adjustable wall in its selected position. The separation of the fibres can be accurately controlled without damaging them and without producing dust, thereby providing a better quality non-woven fabric.

Title: Intercommunication system with selective calling - uses codes signals to alert slave stations branched from common line
IPC: H04M9/02
Filed: 1974-09-17
Abstract: The master and slave stations are connected by a single pair of wires. The slave stations can be called selectively by the master and acknowledge by an audible signal. The stations consist of a low frequency amplifier, a speaker/microphone, and press-to-talk switch. The master station selection assembly has a pulse train generator, a power amplifier and a timing device which resets to zero after sending a selected number of pulses corresponding to the slave station called. The salve stations are de-energised until the master sens an initial long pulse, and then count pulses until the corrent number is received by a called station, which actuates a sound generator, and energises the slave amplifier.

Title: Under-surface heating for roads - has heating elements anchored and protected by watertight membranes
Inventor: MAILLARD GEORGES
IPC: E01D19/08
Filed: 1974-12-19
Abstract: The heated road surface contains heating elements (6) encased in a layer of asphalt (8) forming a water-tight membrane. The surface should preferably have two such layers with the heating elements resting on the lower one (3) and being encased in the second (8). The heating elements are laid onto a sheet of metal (5) such as aluminium, placed on top of the bottom layer (3) and are held in place by means of staples attached to steel beams (7). The advantages of this surface are that it is water-tight, preventing water damaging the heating elements, and the heating elements are securely anchored, avoiding any possibility of their rising to the surface under the constant pressure of traffic.

Title: Radar system for use at sea - has circuit with comparator for detection of peripheral portion of zone of marine clutter
Inventor: MARINO PAUL
IPC: G01S7/292
Filed: 1975-01-24
Abstract: The marine clutter consists of a series of point echoes and the anti-clutter circuit is designed to prevent these from appearing on the radar screen. The comparator produces a comparison between the received signals and given frequency of oscillation. There is a bistable locked to the signals from the monostable. Signals may be compared with signals from the previous sceep so that transient signals such as clutter due to waves of the sea may be ignored.
