Title: Swashplate type hydraulic pump or motor - has cylinder block keyed to shaft in plane of swashplate seating
IPC: F04B1/12
Filed: 1975-04-23
Abstract: The machine has a rotating shaft which carries with it a cylinder block containing axial cylinders with reciprocating pistons. The pistonss have spherical ends which seat in an annular groove in an inclined swashplate which remains stationary and is supported on a semi spherical end cap (2) on the shaft (3). The cylinder block (1) is keyed to the shaft and has a small diameter nose on its end projecting inside the semi spherical cap (2). The key between the cylinder block and shaft runs in this end piece. The plane of the force between shaft and cylinder block therefore runs through the centre (O) of the semi spherical end cap which eliminates the couple between swashplate and shaft that would otherwise exist.

Title: Frequency mixer using surface elastic waves - works at HF, can withstand thermal shocks and is made of piezoelectric material
Inventor: AULD BERT
IPC: G06G7/195
Filed: 1975-07-17
Abstract: A frequency mixing surface wave module provides an output which is a multiple of the two input carrier frequencies. The module is intended to be sufficiently robust to withstand thermal shocks and to be able to operate at high frequencies.

Title: Electronic fire alarm network with minimized wiring - between the central control unit and the detactors and alarm devices incorporating certain equipment operational checks
Inventor: LEROY JEAN-CLAUDE
IPC: G08B29/02
Filed: 1975-09-29
Abstract: An electronic fire alarm network, in which the wiring between the central electronic control unit and the monitoring and alarm devices is reduced to a minimum, is presented. Monitoring devices of various kinds can be used, such as ionization, optical smoke detection, temperature, or fire gas detection transducers, whilst the alarm devices may consist of optical or audio alarms, or automatically operated fire doors, driven electrically. Basically, each transducer is connected via a diode (11) between the lens of one transmission line pair, which services a number of these in series. A monitor circuit (15) is connected at the end of this line remote from the central control, so that line faults are detected. The current to the transducers is supplied down the same line. In parallel with the transducers are the alarm devices (10) supplied by the same line pair but connected via diodes (19), in the opposite sense. When a transducer signal is positive, the central control rewires the current in transmission line pair by means of a relay (8) and the alarms are operated.

Title: Rocket projectile with rear flame shield - has detonator chain with safety pin disengaged by flame shield release
IPC: F42C15/184
Filed: 1976-04-08
Abstract: A detonator system is intended for use in an explosive projectile, in which the rear end of the detonator separates from the main part of the projectile as it leaves the firing tube. The shell of the projectile contains a pyrotechnic detonating chain, which comprises an interrupter disc which is initially locked in its safety (non-firing) posn. by a safety-pin; this safety-pin is biased by a spring acting on a piston attached to the safety-pin in a direction (towards the rear of the projectile) in which it bears against a stack of microspheres contained in a cylinder. The rear outlet opening of this cylinder is initially plugged by a stopper connected to an inertia block; this inertia block is locked to the shell casing by a shear pin. After the shell is fired, the inertia block shears the pin and releases the stopper from the aperture, permitting the microspheres to discharged, which in turn allows the safety-pin to release the interrupter disc, so that the pyrotechnic detonator chain is ready for firing upon impact. Used partic., for relatively heavy projectiles which are fired from a relatively light firing tube operated by a small team. A slidable unit connected to the rear end of the projectile forms part of an assembly for concealing the flame of discharge of the rocket projectile. This unit is disconnected from the projectile on firing.

Title: Purification of furnace gases contg. dust and volatile chemicals - by sedimentation of dust in two expansion chambers with intermediate cooling
Inventor: AVELINE R
IPC: B01D5/00
Filed: 1977-02-15
Abstract: Hot gases from a furnace loaded with dusts and volatile chemical substances, e.g. alkalis, that have a condensation temp. close to the exit temp. from the furnace, are passed directly into an expansion chamber. In this chamber some of the dusts settle out and these dusts are returned to the furnace. The first chamber is linked to a second expansion chamber by a duct with increasing cross-section to reduce the speed of the gases. In this duct the gases are cooled to e.g. 350-450 degrees C. by dilution ambient air or water, to promote sudden condensation. The cooling air is blown into the duct through multiple jets to encourage mixing. A second settling out of dusts takes place in the second expansion chamber. A draught fan then withdraws the gases from this chamber and discharges them to a chinney. Used in purification of hot furnace gases in e.G. cement making or similar industries. The two expansion chambers allows sepn. of polluted and less polluted dusts.

Title: Decorating plastic mouldings e.g. furniture with pigmented paints - using a superficial resin varnish to bind the paint to the surface
IPC: B05D7/02
Filed: 1977-02-25
Abstract: Moulded resin surfaces are decorated by application of a conventional pigmented paint covered after drying by a resin varnish which can bond through the paint to the supporting resin surface. The surface to be decorated is first washed and degreased and opt. pre-coated with a varnish which will key both to the support and to the subsequent superficial varnish. The paint may be cellulosic based and carry a powdered, opt. metallic pigment. The superficial varnish is pref. a polyester, (I), a polyurethane (II) or an acrylicpolyurethane (III). Paint is suitable for decorating non-planar shapes, such as furniture, with coloured patterns individually or in small quantities without excessive cost and permits use of paints normally used on wood and which key poorly to a resinous supporting surface. It is not restricted to flat or near flat shapes, unlike laminates decorated by incorporation of printed papers during moulding.
