Title: Concrete mixer rotary sieve - cylindrical chamber divided by diaphragm with orifice in centre
IPC: B07B1/08
Filed: 1974-02-28
Abstract: The sieve comprises a cylindrical chamber (1) divided into two compartments by a diaphragm (2) with an orifice in the centre. At this point there can be a grille stopping passage of large particles into the lower compartment, and on top of the diaphragm there can be centripetal blades (4) directing the material towards the centre. The lower end of the chamber can be closed by a sieving panel (7). In the lower compartment zigzag members can be mounted, so that the material cannot flow directly in the radial direction towards the outside, at which point there is a spout for the discharge of large particles.

Title: Heat exchanger attached to double walled chimney - has spiral water tubes with water heated in counter flow to hot gases
IPC: F28D7/02
Filed: 1975-02-14
Abstract: The heat recuperator is for a boiler which can also be the chimney and is double-walled. The hot gases travel up inside the inner wall and also through the annular space between the inner and outer walls. Water passes through the inner wall in counter flow to the hot gases passing upwards inside it. The outer wall consists of a sheet, onto the outside of which is welded a coil made of sheeting suitably formed. Thus a double coil can be formed by welding on a continuous U section spiral, and bridging the space between two coils with a welded-on strip. Water can also be passed through these coils, either in counter-flow to the hot gases, or in the same direction. Suitable water feed and return pipes are fitted top and bottom.

Title: Coke oven gas cooling liqs. sepn. - by static decanting and centrifuging of small fraction
IPC: C10G33/06
Filed: 1975-11-14
Abstract: The liquors resulting from the cooling of coke oven distn. gases are collected in a static settling-out vessel, and a single fraction is drawn off from a level determined beforehand, to be sepd. centrifugally. The level selected is the one at which emulsions of water and tar collect in a zone below that in which there is little tar and above that contg. little water. The settling out of the liqs. can be effected continuously, and the emulsion content is kept down so that there is no problem as regards obtaining a liq. which can be recycled for cooling, and a tar very low in water content. Existing plant needs very little modification. Only a small quantity of the liq. in the settling out vessel located at a fixed height is extracted and centrifuged.

Title: Screw pump rotor coating appts. - uses template to control travel of carriage mounted spray nozzle
Inventor: RANCHON JEAN
IPC: C23C4/16
Filed: 1975-12-31
Abstract: The apparatus is intended for coating the helical rotor of a screw pump with a powdered material prior to heating. Thus a wear and corrosion resistant coating is formed on its surface. A copying system is used for the powder application. The workpiece (1) is rotated between a centre (6) and a drive member (4) at constant speed, while the spray nozzle (15) is maintained at a constant distance (a) from its surface. In one design, the spray is mounted on a carriage (7) with a sensor (13) projecting from the opposite end, to travel along a template (11) in the form of a block identical with the workpiece. This controls the movement of the nozzle. In another design, a rod with a helical groove forms the template. In another design, the cam follows a groove in a straight rod, but gears are used to control the nozzle position.

Title: Impact operated aerial bomb - has pull and rotary vane operated striker forming delay before actuation of double primer charges
IPC: F42C15/295
Filed: 1976-04-08
Abstract: The bomb designed to explode on impact has a delay device (12) for aiming the fuse (10) after release of the bomb from an aircraft, a priming device (14) of inertia type and a pyrotechnic chain (16) to cause the primer to ignite the explosive charge (126). The delay system has a striker (20) with a spring (22) around it, retained by a ball (24). This fires a cartridge (32) when released. This is held in a block (44) with channels holding two explosive charges (34) to operate another cartridge (36) which operates a piston (40) down the middle, to move a spindle (18) which releases the primer (14). This action severs one or more shear pins. The block (44) is also released by a screw (60) and nut (48) drive operated by vanes (46) mounted on the end of the casing. The ball (24) is released to initiate the whole system when a ring (64) at the top is pulled. Finally, the primer (14) has a percussion device (74) to ignite another primer (80) on impact.
