Title: Perforated disc type pressure filter for gases - with coupled rotary scrapers to detach cake from discs surfaces
IPC: B01D46/24
Filed: 1975-03-19
Abstract: Perforated disc-type pressure filter for gases, has a filter casing housing a stationary, hollow shaft serving as a filtrate outlet and carrying a coaxial set of filter discs leading into the shaft bore, as well as inter disc scrapers to remove filter cake from disc external surfaces. The discs reamin stationery with respect to the casing and radial scrapers can be rotated about the axis of the hollow shaft by actuation of a mechanism outside the filter casing. The scrapers are pref. linked together by drive transmission rods and the drive to the end scraper is via a crank pin on the back of a pin wheel which is turned by a pinion forming part of the mechanism. Used for sepg. entrained solid particles from a gas sream, partic. suspended dust arising from the prodn. of oxides of cadmium, magnesium and zinc, chloride of lime etc. The simplified, inexpensive construction allows easy dismantling and reassembling when servicing. Hightly efficienc cake remov oval permits filter to operate at a low pressure loss. Depth of filter cake can be varied during filtering by using blades which rotate slightly about their axes when rotation is reversed thus altering blade orientation to cut nearer the disc surface.

Title: Retractable drawer for banknotes - has drum and brake system which permits rotation of drawer into retracted position but not in opposite direction
IPC: G08B13/10
Filed: 1975-07-29
Abstract: The retractable draw (19) has compartments 27) for bank notes. The drawer can rotate around an horizontal axis under the effect of an elastic spilling force (19) from an open bank note access position to a retracted position with no access to bank notes. The retracting system includes a unidirectional braking device which permits retraction of the draw but opposes movement in the opposite sense. A rack (69) is part of a drum (61) which cooperates with a rotatable brake shoe (64). The brake shoe is at a variable distance from the axis of rotation (64). When it is driven by the drum (61) in the draw retracting direction no braking action occurs. Rotation in the opposite sense brakes the drum.
Patent FR-2322322-A1 (FR)
Title: Gastight drill tube connection - by specified taper faces on tool joint and spigot ends producing second metal-to-metal seal
IPC: F16L15/06
Filed: 1975-08-29
Abstract: Gas-tight connection for drill pipes, used in deep wells, is produced by terminating the internally threaded part of the tool joint by a cylindrical plain bore, ending in a re-entrant taper face. The taper angle of the latter is 5-20% greater than the angle of the tapered face at the spigot end of a drill tube. The relative actual dias. of spigot end and of bore are such that a gap is left which is closed when the joint is tightened. This leaves greater tolerances for manufacturing accuracy without endangering the gas-tight seal. The danger of premature wear by friction or of fretting and damage is completely eliminated.
Patent FR-2323940-A1 (FR)
Title: Milking system three way valve - has body with two coaxial seats and rod connected to core of electromagnetc attached to lower chamber diaphragm
IPC: F16K31/40
Filed: 1975-09-09
Abstract: The three-way valve has a body (2) with two coaxial valve seats (18, 21). The valve rod is connected at its lower end to the core (8) of an electromagnet (7) which is attached to a flexible diaphragm which seals off the lower chamber (3). When the solenoid is de-energised the armature (9) seals the air inlet with the washer (10). When the solenoid is energised, the inlet is opened allowing atmospheric air to enter and lift the diaphragm (5). This action opens the lower valve (18) so that a vacuum pipe is connected to the milking machine through the chamber (22).

Title: Ester of erythromycin and para-chloro-phenoxy-isobutyric acid - by reaction of erythromycin with an active form of the acid in a polar solvent containing an organic base
Inventor: PERIS JUAN VERA
IPC: C07H17/08
Filed: 1975-09-12
Abstract: Process for the prepn. of an erythromycin ester of p-chlorophenoxy-isobutyric acid by reaction of erythromycin with an active form of p-chlorophenoxyisobutyric acid (such as the chloride) in a polar solvent (pref. methylene chloride) in the presence of an alkylic base (e.g. triethylamine). Antibiotic which is better and more completely absorbed than erythromycin and gives higher tissue concentrations and has better solubility in fats. The exact structure of the ester has not been determined, but evidence shows that the C-9 and C-6 hydroxy gps. of the erythromycin are not involved in the ester formation.

Title: Magazining dwell pressures during injection moulding - using hydraulic circuit, to shorten cycles by concurrent plasticisation for the next shot
Inventor: QUINET JEAN-PIERRE
IPC: B29C45/57
Filed: 1975-09-26
Abstract: An ancillary hydraulic system for a screw injection moulding machine to maintain the packing or dwell pressure on the melt entering the mould, and allowing the screw to retract and plasticise more material concurrently with the dwell stage of injection. A conventional reciprocating a non-return valve. Downstream from the valve is a small side chamber contg. a plunger. The plunger is moved by a hydraulic ram on a variable pressure circuit interconnected with that for the ram for the main screw. The relative ram forces can be adjusted so that during mould filling with full pressure on the screw, (a) the plunger can be advanced sufficiently to completely purge the side passage but (b) at the end of the initial shot can be retracted to allow the screw to fill the side passage. The ancillary circuit can then be isolated to maintain a suitable mould packing dwell pressure via the ancillary plunger while the non-return valve remains closed to allow the screw to retract etc. The plunger cam pressure can be relieved to allow the tool to be opened and the moulding ejected without any pressure on the melt in the runners and mould gates. Esp. suitable for moulding crystalline or semicrystalline materials, viz certain polyolefins, to compensate for contraction within the material in the mould cavity. The packing pressure is readily set to optimum levels. Overall mould cycles are reduced significantly by performing plasticisation for one cycle concurrently with the dwell stage of the preceding cycle. There are no blind recesses in the flow paths in which moulding material could hang up and degrade.

Title: Hang glider with air brake - has vertical member carrying pocket controlled by Bowden cable and can pull glider out of dive
IPC: B64C31/028
Filed: 1976-01-08
Abstract: The main wing of the hang glider is mounted on the tubes (3, 4) which carry the vertical member (2) and the lower frame (5). The vertical member (5) carries a pocket (16) which is normally held closed by the Bowden cable (18) pulling on the sliding ring (13). Should the glider get into a dangerous dive the pilot operates the lever (23) which releases the catch (21) which, in turn, releases a second sliding ring (19) and consequently the first sliding ring (13). This ring (13) rises up the tube (2) until it reaches the stop (9) allowing the wind to blow into the pocket (16) and create a force which pulls the glider out of the dive.
