Title: Anti-burglar device - comprises small explosive cartridge triggered by spring loaded hammer if door or window is opened
IPC: G08B15/00
Filed: 1980-03-20
Abstract: The anti-burglar device comprises a cylindrical hollow body along which a shaft carrying a hammer may slide. The hammer is held back against a compression spring so that if released it is fired down towards a cartridge. The lower end of the cylinder has a removable fitting holding the cartridge with its charge uppermost. A mechanism attached to the top of the shaft normally holds the shaft in its withdrawn position, but if the door or window to which the mechanism is attached moves, then the hammer is released and fired at the cartridge, igniting the charge. Electrical contacts may simultaneously be closed to switch on an alarm or light.

Title: Mfg. compressed granular filter element for domestic water supply etc. - using mixt. of diatomaceous earth and improved kieselguhr
IPC: B01J20/14
Filed: 1980-06-20
Abstract: An industrial process for the mfr. of filter elements of the type which are made up by compression moulding a mass of granular material. A mixt. is made up contg. 80 wt.% diatomaceous earth and 20 wt.% improved kieselghur. The mixt. is satd. with water and sepd. as a moist paste which is put through a granulating cyclone and then degassed in an extrusion press which deposits a series of equal vol. pieces. Each piece is compression moulded at high pressure to the required shape of element and then heated in a furnace. The furnace treatment pref. consists in raising the temp. of the moulded pieces progressively to 1000 deg.C and then cooling gradually. Used for mfg. compressed, granular filter elements for the purificn. of fluids, e.g. domestic water supplies. The granular structure of the element has greater homogeneity than that of previous granular elements, so filtration reliability is improved. The process produces a low reject rate and inspection level can be reduced.

Title: Treatment of precoated sheet metal before working - by coating with water-soluble lubricant
Inventor: PICHANT PATRICK
IPC: F16N15/00
Filed: 1980-08-18
Abstract: Treatment of precoated sheet metal (e.g. steel or Al) to improve the behaviour of the coating during working of the metal is effected by applying a layer of water-soluble lubricant to form an adherent film without altering the underlying coating.

Title: Continuous sponge iron prodn. in shaft furnace - using scrubbed recycle gas, part of which is passed through a gas generator
Inventor: SANTEN SVEN
IPC: C21B13/00
Filed: 1981-02-26
Abstract: In a continuous sponge iron prodn. process, CO2 and H2O are removed from the furnace exhaust gas which is then split into at least two streams. One stream is passed into a gas generator where it is heated by a plasma burner and injected with an oxidant and a solid reductant to form a gas mixt. comprising mainly CO and H2. This gas mixt. is held at a temp. such that the ash content of the solid reductant forms a slag, is mixed with at least one of the other gas streams to adjust its temp. to that required for iron oxide redn. in the furnace, and is then injected at the bottom of the furnace. The oxidant is pref. water and the reductant is pref. coal. The ash content of the coal forms a slag which is easily removed so that problems of ash deposition in the installation are avoided. The hydrogen content and the temp. of the final reducing gas are controlled to the required values.

Inventor: GLIZE JEAN-PIERRE
IPC: G07F7/08
Filed: 1981-03-05
Abstract: A system for verifying an operation in particular one that includes payment, the system comprising at least one terminal (11) and a plurality of portable objects (10) which may be coupled, preferably without contact, to the terminal. The terminal emits repeated interrogation messages suitable for triggering reading of the contents of a shift register (60, 190) in a portable object when said object is coupled thereto, only after a comparator has verified concordance between first validity data from the portable object and check data from the terminal. After processing, the terminal re-writes updated useful data in the register. Re-writing is only authorized after a comparator (240) has verified concordance between second validity data stored in the shift register with check data transmitted by the terminal into a register (220) of the portable object. The check data is produced by the terminal after decoding the validity data contained in the message derived from reading the portable object (10).

Title: Implement for planting in spaced rows - has offset sights to follow reference line as counter offset tool marks next reference line
IPC: A01B69/02
Filed: 1981-06-01
Abstract: The implement uses simultaneous tracing and marking operations to effect the planting of vegetables in evenly spaced rows, laterally offset sights being used to follow a pre-marked ground reference line whilst the succeeding reference line is marked out by counter-offset equipment. The operations are carried out on a tractor, the sights being offset on one side of the longitudinal tractor axis whilst the reference line marking equipment is offset on the other. Planting takes place at the same time in one or more rows between the reference line and the marking equipment, the distance between reference lines and adjacent plant rows equalling half the row spacing. Plants may be placed automatically at equal longitudinal intervals, using bosses on a revolving plate with the interval related to the circumference of a road wheel.

Title: Wear resistant underground cutting machine chisel holder - has surface hardened hole for shaft and contact face for collar
Inventor: PIETSCH HARTWIG
IPC: E21C35/18
Filed: 1981-06-17
Abstract: A hole to accommodate a chisel shaft crosses over at the top into a contact surface with the chisel collar lyino against it, on a steel holder for a tool used for cutting away pieces of rock and mineral, connected to the base unit of the cutter head of a forward-driving or mineral-extractino machine. Both the hole (1) and the contact surface (2) of the chisel holder are hardened on the surface. The hole and contact surface pref. have hardness of 52-65 HRC on the Rockwell scale, to a depth of 0.5-3 mm. The rest of the holder is pref. less hard, at 38 -51 HRC. The hole and contact surface can be hardened by induction. This combines low production costs with a high degree of resistance to wear.
