Title: Temp. control of exit channel from glass tank - using two sets of measure-ments individually controlling heating and cooling devices
IPC: C03B7/06
Filed: 1972-08-09
Abstract: Glass flowing out from a melting tank through a channel with >=2 sections is heated by a set of burners and cooled by a set of air jets. The temp. of the glass is detected at the top and bottom of the channel at the exit end of each section and signals are produced giving two different sets of temp. profiles. One set of profiles is used to control the input of heat from the burners, the other set to control the flow of cooling air in each channel section, so as to maintain a set of constant temp. conditions the length of the channel.

Patent FR-2223116-A1 (FR)
Title: Continuous bar extn. on continuous casting machines - at controlled speed using spring-loaded levers mounted on reciprocating slides
IPC: B22D11/128
Filed: 1973-03-30
Abstract: A horizontal tube is fixed to a vacuum chamber holding the molten metal, and two circular slides are mounted on the outside dia. of the tube. Each slide has two nuts at 180 degrees which run on threaded spindles. A frame houses the two spindles which are driven by a worm gear which is reversible. Each spindle has a section of left-hand and right-hand thread, so that when it rotates in one direction, one of the slides moves a specific distance to the right while the second slide moves the same distance to the left. When the direction of spindle-rotation is reversed, the direction of the slides is reveresed, so a reciprocating motion is achieved. Each slide is fitted with four spring-loaded levers which project through slots in the horizontal tube so that they are set at a narrow angle to, and in contact with, the continuous cast bar. When one slide moves in the direction away from the vacuum chamber, the levers engage with the surface of the cast bar, propelling it at the desired spped. During this cycle, the other slide is moving in the reverse direction during which the levers slide along the cast bar, i.e. they only engage the bar when travelling in one direction. The device is gas-tight and can be used under vacuum or inert gas; it is mainly for melting electrodes for sec. melting in electro-slag furnaces, vacuum-arc- and induction furnaces.
Patent FR-2230066-A1 (FR)
Title: Turning indicator flasher and battery charger for motorcycles - can be used without battery and requires minimal power
IPC: B62J6/00
Filed: 1973-05-15
Abstract: The device may be transistorised or non-transistorised. The non-transistorised concept consists basically of an electromagnetic relay re with contacts CT1 and CT2, a capacitor C1 and a resistor R5. The contacts CT1 and CT2 are normally open when the relay is not energised. For the flashing operation, the contact CT1 is initially open. With Com connecting LAR or LAV turning indicator, the relay coil Re becomes energised after capacitor C1 is fully charged from the dynamo VM. Contacts CT1 and CT2 are then closed and connect indicator LAR or LAV to VM. Whe the voltage at fuse F2 is equal to the voltage at C, the relay is de-energised. The flashing operation is then repeated without demanding power from battery B. For the charging operation, the battery B may be charged through a positive coefficient temperature resistance CTP, resistors R4 and R4', and diode D4, or through CT2.

Title: Compsns for integral-skinned flexible polyurethane foams - for materials of good reproducibility and tear-strength characteristics
IPC: C08G18/50
Filed: 1974-06-28
Abstract: Microcellular polyurethane foams with flexible integral skin are mfrd. by the 'one-shot' method. All constituents are liquids at room temp.
