Title: Infra red detectors with improved sensitivity - using phase change in mixed crystal of lead and barium zirconates
IPC: H01L37/02
Filed: 1974-03-25
Abstract: Pyroelectric detector with a pyroelectric crystal operating in a region where the spontaneous polarisation depends not only on the temp. but also on a phase-transition between a ferroelectric- and an antiferroelectric- phase of different crystal structures, the result being improved sensitivity in i.r. detectors for temp. measurement or in image prodn. using several detectors in a matrix or a vidicon. A mixed crystal is used, either lead zirconate and barium zirconate (I) or sodium niobiate and lead zirconate. By altering the compsn. of the mixed crystal, applying a polarising field, and using heat, if necessary, devices can be applied over a wide temp. range and in many applications.

Title: Pump for liquid fuel in vehicles - has truncated conical stator halves and rotor and perforated wall at outlet
Inventor: BOTTOMS HARRY SIMISTER
IPC: F04D13/06
Filed: 1974-06-19
Abstract: The pump has a rotor which forms two aligned truncated conical shaped chambers. A rotor arrangement is placed between these chambers, so that the chamber ends with larger diameters form inlets for the pump. This pump is used especially for liquid fuels and the rotation of the rotor pumps liquid by centrifugal effect to the pump outlet. The aligned truncated conical chambers (13, 14) accommodate the rotor (15). The first hollow truncated conical element (18) has a passage which is coaxial with one of the truncated conical chambers (14) so that a chamber of circular shape is formed within this chamber. The smaller diameter of the first element points in the direction of the rotor.

Title: Plant growth regulators for cereals - contg. (2-chloroethyl)-trimethyl-ammonium chloride and other active ingredients
IPC: A01N37/02
Filed: 1974-11-14
Abstract: Plant growth regulators, partic. for cereals, contain as active ingredient a combination of (2-chloroethyl)-trimethylammonium chloride (CCC) with other agents, namely with alkali or ammonium salts of 2,3-dichloroisobutyric acid for wheat, barley or rye, with metopiron for wheat or barley, or with N,N-diethyl-nicotinamide for barley or rye. The growth regulators increase lodging resistance of cereal crops by thickening, shortening and strengthening the stem without diminishing grain yield. The combination of CCC with other agents reduced the amt of CCC required and thus minimises toxicological problems.
Patent FR-2271387-A1 (FR)
Title: Rotary sliding vane pump or motor - has vanes inclined in rotor slots to form sliding contact line seals
IPC: F01C21/08
Filed: 1975-03-13
Abstract: A rotary hub contains radial slots accommodating the sliding vanes and runs in a roughly cylindrical body which has inlet and outlet ports for the gas or liquid handled and an inner wall forming cams. Each vane is so shaped that it can tilt sideways in its slot, thus forming a sealed line contact with one of the slot walls near the mouth. The vane tip extending beyond the line of contact is thinner than the rest of it. Thus when the cams thrust the vanes back into their slots as the hub rotates, the line of contact moves radially inwards with the vanes. The gas or liquid exerts a pressure over a large area of the vane so as to keep it in the inclined position.
Patent FR-2325826-A1 (FR)
Title: Plunger pump drive mechanism - comprises ball bearing on eccentric and rolling against piston with return spring
IPC: F04B9/04
Filed: 1975-03-21

Patent FR-2268619-A1 (FR)
Title: Electronic control circuit for injection moulding machines - for automatic control of hydraulic pressure during moulding cycle
IPC: B29C45/77
Filed: 1975-04-10
Abstract: The circuit is for determining the moment for switching from the injection pressure to the post-injection pressure in injection moulding machines, depending upon the die-locking pressure. The time used for the injection pressure is reduced so that a pressure pulse is superimposed on the pressure curve formed by the injection- and post injection-pressures, but the resulting total pressure on the curve is always below the pre-determined locking pressure for the die. The pref. device consists of recording appts. for the pressure curve plus a device for switching to the post-injection phase from a pre-determined injection pressure. Prevents the die opening during the injection phase and thus ensures that the mouldings are dimensionally correct and free from defects.

Title: Sheet metal impeller for centrifugal pump - has ridges on inlet eye spigot to form clearance wi. casing
IPC: F04D29/22
Filed: 1976-11-05
Abstract: A centrifugal pump has an impeller (11) carrying radial sheet metal blades enclosed by front and back discs made from metal sheet, the front disc (8) being welded together from two sheets (6). This disc continues as an annulus (2) beyond the entries of the blades to form an inlet spigot the outside of which forms a small clearance (4) with the inlet side of the casing (3) to reduce leakage between casing and impeller to a minimum. The outer sheet (8) of the front disc has ridges (12) which take up a large space between the impeller spigot (2) and the casing and leave the small clearance (4) between their outer peaks and the casing. This makes it possible for a sheet impeller to replace a cast one.

Title: Uniform quality calendared films - produced by using calendar itself to monitor viscosity and adjusting material preprocessing accordingly
IPC: B29C43/00
Filed: 1977-01-04
Abstract: The films are produced by determining the viscosity of the processed material immediately before it enters the calendar or whilst in the calendar and controlling the degree of plasticisation accordingly. The viscosity depends upon e.g. molecular weight, polymer prodn. details, plasticiser, lubricant, fillers etc. so that different mixes can have equal viscosity at different temps. The calendar itself is used as the viscosity meter, utilising the material pressure on the rollers, the rollers gap and speed and the width of the material as parameters. Process produces higher degree of uniformity than hitherto obtainable, it is suitable for e.g. PVC, other thermoplastics or rubber.
