Title: Continuous casting mould - has vertical slots and is rotatable
IPC: B22D11/14
Filed: 1972-03-02
Abstract: The mould has vertical slots distributed evenly on its circumference starting at least 200 mm away from the top and extending downwards to have a length amounting to 50-85% of the mould height. The mould is mounted in a device permitting its reciprocal axial rotation over an angle equal to the spacing between adjacent slots. This results in the even distribution of the oolant in the slot zones, into which the coolant is injected by nozzle rotating together with the mould. The system ensures a uniform solidi cation front of the section being cast.

Title: Continuous coating of boards with thermoplastic film - using equipment which feeds and discharges via stacks
IPC: B05D1/26
Filed: 1972-10-16
Abstract: Plastic covered sheets made by equipment which accepts a succession of closely spaced individual boards dispensed from a stack and conveys them beneath a die extending a curtain of molten thermoplastic film. The coated boards pass through a calender nip with a large dia. chill roll before removal by a second conveyor system to another unit for restacking the freshly coated boards. The surface texture of the steel chill roll depends on whether a glossy or satin coating surface is required. The path of the haul-off conveyor may be adaptable to optimise the contact path length between the coated boards and the chill roll. Ancillary cutters may shear the film bridge between adjacent coated boards. It is suitable for the mfr. of e.g. plastic coated book covers, using transparent film to cover freshly printed boards which are too stiff to be accepted by equipment loaded from or discharging to spools. Stacking devices can be continuously replenished/unloaded so there are no interruptions.

Title: Felt panel is coated with water soluble thermoplastic - to allow it to be secured to e.g. a garment
IPC: D06M23/18
Filed: 1973-05-03
Abstract: A felt panel is coated on one surface with a film of water-soluble thermoplastic adhesive, whereby the panel can be secured to e.g. a garment by hot pressing. The felt panel may be used as a decoration, or may form part of the garment e.g. a pocket. The panel is cheaper and less likely to be damaged than panels having a coating of pressure sensitive adhesive. The use of a water soluble thermoplastic eliminates the use of an organic solvent (which may damage the felt or garment) when applying the thermoplastic layer to the felt.

Title: Manufacture of fast switching semiconductors - uses RF heating, cleaning and doping processes use same vaccum chamber
IPC: H01L21/00
Filed: 1974-02-26
Abstract: Semiconductor devices such as thyristors, transistors and diodes are constructed so as to decrease the rise and fall times of switching operations by precise and repeatable introduction of dopants producing recombination centres. The semiconductor structure is based on a monocrystalline slice on one side at least of which eliimination of impurities has taken place to a depth of at least 100 angstrom by an ionic attack process. This is followed by the deposition of a layer between 50 and 200 angstrom thick by ionic bombardment and cathodic pulverisation, both being carried out in the same chamber at RF generted temperatures.

Title: Display system for electronic temp. controller - includes potentiometer with reduction gearing in knob to drive non:linear scale compensating for non:linear response of temp. sensor
IPC: G05B1/02
Filed: 1974-05-17
Abstract: The device described displays the values of signals used in electronic controllers and is partic. used to display temperature values as a function of analogue command signals. A single- or multi-turn potentiometer (7) is used. The final setting of the potentiometer is registered on a clock or counter included in the reduction gearing of the potentiometer knob (14). The temperature approached is read directly on a dial which gives the overall operating range of the instrument. The dial makes a single rotation to cover this range. The scale driven by the geared-down knob has markings arranged so as to compensate for the non-linearity of the sensor output w.r.t. temperature.
Patent FR-2273995-A1 (FR)
Title: Lubrication bottle for compressed air systems - can be isolated from system for refilling, direct access not necessary (SW-12.1.76)
Inventor: MAZZOLENI CYRILLE
IPC: F16L55/00
Filed: 1974-06-04
Abstract: The bottle has two reservoirs, the inner (1) feeding oil into the system through a tube (5), the outer (2) holding the reserve supply. Both are interconnected, by upper and lower passages (6, 7, 8, 9) to each other and the compressed air. Underneath the outer reservoir is a connection (13) for an oil supply tube (14) and, passing axially through the two reservoirs and into this, is a spring loaded rod (11, 27). For refilling, pressurised oil is passed through the connection underneath. This pushes up the axial rod, sealing off the air bleed passages and the inner reservoir, allowing oil to be passed into the outer reserve supply.
Patent FR-2265481-A1 (FR)
Title: Hydraulic oil control valve circuit - for high pressure oil reservoir on pressure die casting machines
IPC: B22D17/32
Filed: 1974-07-05
Abstract: In a control device for the oil reservoir valve on an oil dynamic press for the pressure die casting of metals, oil pressure constantly tries to open the valve but an auxiliary oil circuit maintains it in a closed position using a plunger element sliding in a valve body provided with an outlet channel which leads to the auxiliary circuit. A choke element on the plunger regulates the quantity of oil flowing through the channel and thus opening or closing the oil reservoir valve. This provides better control on the injection of molten metal into the die cavity, esp. the avoidance of high pressure surges.
