Title: Purificn. of industrial effluent by ion exchange treatment - with immersed exchanger which is replaced during regeneration
IPC: C25D21/22
Filed: 1975-04-29
Abstract: Purificn. of polluted liq. such as industrial effluent is by ion exchange treatment. A portable, ion exchange unit contg. a suitable resin is immersed directly in a tank of liq. to be treated, the liq. being pumped continuously in closed circuit from the tank, through the exchanger and back to the tank. When the resin in the exchanger is due for regeneration the exchanger is replaced with another exchanger charged with fresh resin and the first exchanger is taken away to a resin regeneration station, there is no interruption of the purificn. process. Using a constant delivery pump, the rate of flow of liq. through an exchanger is pref. controlled by means of an adjustable delivery by pass line returning liq. directly to the tank, or delivering treated liq. for further use, pref. via a filter. The regeneration station pref. comprises anionic, cationic, and demineralised water baths into which a set of exchangers can be lowered by mobile overhead lifting gear. The resin-loaded exchanger, is also claimed, pref. having a vertical cylindrical case with top connection for the closed circuit line and a liquid outlet at the bottom. Process is used for ion exchange treatment of industrial effluents partic. those from chemical and electrolytic processing plants such as surface treatment plants for metals. Process does not have to be interrupted while exchange resin is regenerated. Cartridge type exchangers are transported in containers for regeneration while stand by exchangers are put into use.

Patent FR-2322732-A1 (FR)
Inventor: TABARY JEAN-PIERRE
IPC: B31B50/72
Filed: 1975-09-05
Abstract: Two or more lengths of seamless tubing, for example artificial sausage casing are assembled by longitudinally aligning the end portions thereof overlapping and joined to each other by an adhesive strip band but for the time without internal communication therebetween. Internal communication between the lengths of tubing is established, for example, by introducing compressed gas into one tubing length remote from junction zone which causes this tubing length to take a cylindrical configuration moving its side walls (defined by its initially flattened shape) apart and thereby the side walls of the second joined tubing length are drawn with the corresponding side walls of the first tubing length by means of the adhesive strip band. As a result thereof the end portions of the side walls initially in contact with each other slide along each other and then out of contact in order to provide continuous internal communication in the tubular assembly. Accordingly the resultant end portions are interleaved as shown herein. A mandrel may be needed in place of the compressed air to separate the side walls and establish internal communication.

Patent FR-2291056-A1 (FR)
Title: Electric contact rail with clip-on support - using two ratchets inside hollow housing is C-shaped and lips are curved inwards
IPC: B60M1/34
Filed: 1975-11-13
Abstract: The C-shaped electric contact rail is fitted to the ratchet teeth of an elastic support clip. The other end of the clip is fitted with similar ratchet teeth so that when the clip is pushed into the hollow groove formed by the lips of the insulatin strip supporting the rail, the ratchet teeth clip behind moulded ridges in the walls of the lips. The front of the lips are curved inwards to protect the rail and to guide the arm of the pick-up shoe. The elastic clips hold the rail away from the walls of the insulating support strip and thus prevent the strip from overheating. The rail mounting also ensures a circulation of cooling air. The rail and clips are mounted in the strip simply pressing through the elastic lips.

Title: Laminated razor blade with bonded cutting edge - has ceramic material layer enclosed by metal or plastics layers (NL130776)
Inventor: PELECKIS ANTHONY JOHN
IPC: G01N1/06
Filed: 1976-01-08
Abstract: The laminated razor blade is made especially from a substrate material with unsatisfactory surface finish or with minimum dimensions which cannot be processed by conventional methods. The cutting edge of the razor blade is joined to the laminated material or an amorphous metal alloy. The first layer can be a thin strip of ceramics, refractory material, or an amorphous alloy and the second and third layers can be thin metal strips. These second and third layers can be thin strips of steel or aluminium, or thin plastics strips. The first lay er thickness is non-uniform and the cutting edges are joined to this material layer. The arrangement enables a cutting edge to be formed at the first layer.

Title: Child proof cap for screw necked containers - has cylindrical bore on container neck and conical bore with ratchet teeth engaging projections
IPC: B65D50/04
Filed: 1976-01-27
Abstract: The inside surface of the truncated conical plastics cap (1) consists of a cylindrical projection (9) which fits inside the neck of the container, sealing it hermetically; an internal screw thread (2); a flat cylindrical bore (7) which rests freely on the last thread of the container neck (11) and a conical bore (4) which extends to the lower edge (1a) of the cap. Inside the conical bore are two projections (5) in the form of ratchet teeth which are placed diametrically opposite. When the cap is screwed down these teeth clip over two small projections (10) on the neck of the container and the cap cannot be unscrewed unless lateral pressure is applied to the flat spot (13) on the cap, deforming the cap section and thus releasing the ratchet teeth.

Title: Vertical centrifugal separator drum - has distributor head connected to spinning hollow shaft for solid fraction evacuation
IPC: B04B1/02
Filed: 1976-09-01
Abstract: The centrifuge has an open top and consists of a cylindrical shell (12) tapering to the bottom (14) which is attached to a hollow shaft (16). The hollow shaft extends upwards into the cylindrical shell as four supports (18) carrying a conical distributing head (20) with twelve radial grooves (24). The hollow shaft (16) is driven by the electric motor, and seated in ball bearings (25) in the motor housing (28). The inlet pipe (36) supplies the dross on top of the head. The grooves accelerate the dross and eject it towards the inner surface of the shell, and separation takes place. The heavier substance slips down the conical walls to the hollow shaft, and the lighter substance rises until it reaches the circular groove (46) where it is scavenged by a radial pipe (48).
