Title: Sampling lance for molten metals - using disposable refractory bush located in cardboard tube
IPC: G01N1/12
Filed: 1974-11-29
Abstract: The device consists of a jacket or tube made of a burnable material and contg. a refractory bush with a central hole leading to the sample container; the front end of the bush has two mating surfaces, one for fixing the bush in the tube and the other for retaining a cup used as a homogenising chamber.

Title: Powdery material pneumatic unloading system - releases and deflects air at outlet to avoid dust generation
IPC: B65G69/18
Filed: 1975-05-02
Abstract: A bulk discharge system is for unloading powdery material by pneumatic tube, into open-topped hoppers without dust generation. At the tube outlet, the jet of propellant air is released and deflected so that the particles are finally discharged entirely under gravity, without any propulsion by the air, which does not come into contact with the material already unloaded. The expansion device can be a tubular sleeve of straight section and larger diameter than the tube, over which it fits coaxially. The air jet can be broken up by a cone with a number of holes in it, coaxial to the outlet and with the apex towards it, the air passing through the holes.

Title: Dry coke quenching extractor - with swivelling tray for water seal facilitates inspection and repair
Inventor: KULAKOV NIKOLAI KONSTANTINOVIC
IPC: C10B39/02
Filed: 1976-01-21

Title: Vertical storage buffer for flow process control - has storage conveyor linked to horizontal input and output conveyor
IPC: B65G65/00
Filed: 1976-02-18
Abstract: A vertical storage conveyor has an elevator section (22) and a parallel descending section (23). A vertically movable beam (39) with a horizontal transfer trolley (41) links the two storage conveyors. It is placed between a horizontal input conveyor (2) and a similar output conveyor (3). The whole conveyor system forms a link between following stages of a production flow line. The vertical storage acts as a buffer, thus regulating the component flow when supply and demand between the two production stations do not match. This is achieved by transferring the components from the elevator (22) via the transfer beam (39-43) to the descending conveyor.

IPC: B29C45/44
Filed: 1976-03-09
Abstract: Mould tools having the plug and/or cavity mould lined with a flexible material or thick skin which can be deformed to disengage undercut portions of the moulding. Linings may be perforated to accommodate injection nozzles or may be attached to multi-piece supports which can extend the lining to produce lateral contraction for releasing the moulding. Alternatively, the male lining may be supported by hydraulic pressure. Mould tools may be of composite construction, e.g. reinforced polyester mouldings for support and polynorbornene ('Norsorex' RTM) or silicone rubber ('Silastic' - RTM) for the deformable linings. Suitable for producing injection moulded or cast mouldings. Mould construction is simpler than with use of multi piece solid tools requiring relative movement of sliding parts to release undercut parts.

Title: Speed change for magnetic tape recorders - has worm gear drive with belt drive changeover provided by motor reversal through centrifugal clutches
IPC: G11B15/44
Filed: 1977-02-22
Abstract: For normal operation the worn gear (4, 5) with a high reduction ratio transmits motion from a drive shaft (1) to the output shaft. For high speed rewinding of the tape a square cross section belt looped around a free wheel pulley (8) and a clutch coupled pulley is used. A similar clutch is coupled to the worm wheel. The two clutches are of the centrifugal type and respond to opposite drive shaft motions. On this basis a change from fast rewind speed to normal speed is effected by reversal of the motor rotation without any mechanical actuation.
Patent FR-2384309-A1 (FR)
Title: Teaching system using illustrations as memory aid - uses strip illustrations with min. text to teach technical or scientific principles
IPC: G09B19/00
Filed: 1977-03-18
Abstract: The teaching system uses illustrations in the form of a strip cartoon to create a memorising effect and direct visual comprehension. The method rigorously respects the basic principles of the subject treated by the use of maximal visual impact in the form of illustrations. The illustrations facilitate the comprehensive and memorisation of the subject without apparent effort. The exactness of the technique or scientific subject is not reduced, distorted or made simplistic in any way. The memory effect is obtained by using various contrast and effects to interpret the action of the subject treated by means of cartoon illustrations. The illustrations are in themselves sufficient complete to be understood with an indispensable minimum of text.
Patent FR-2348862-A1 (FR)
IPC: B65D41/34
Filed: 1977-04-25
Abstract: The safety closure comprises a screw cap with a threaded part (1) and a safety ring (6). By means of interruptions (2) in the circumferential wall (3) of the screw cap, it is achieved that the threaded part (1) is connected to the safety ring (6) by narrow webs (4) and a broad web (5). The force required for opening the safety closure for severing the narrow webs (4) is thus reduced, it being prevented by the non- severable broad web (5) that the safety ring (6) drops down when the bottle is emptied.

Title: Device for sampling molten metal - giving rapid clean sampling and quick recovery of sample
IPC: G01N1/12
Filed: 1977-04-29
Abstract: Sampling device for taking samples of molten metal from a melt comprises a split metal form located in a mounting which is in the form of a step for inserting into a cardboard cylindrical holder. The shape of the form is such that the sample consists of an ingress tube, a flat sample disc and a test piece. The top of the form is perforated for gas relief. The form is inserted into the mounting between two converging faces which serve to clamp the form closed. The mounting has two collars so that a strip of flammable material can be seated over them and retain the form. The walls of the ingress tube are slightly thicker than those of the rest of the form causing this part of the sample to cool more rapidly than the rest and thus prevent any escape of metal. Sampling is rapid, there is no risk of contamination of the sample metal and the sample is immediately available.
