Title: Improvements In or Relating To a Method for Removing a Concrete Panel from a Form
IPC: B66C1/24
Filed: 1981-07-02
Abstract: A method for removing a concrete panel from a form, where a lifting pressure is applied to the lower side edge of the concrete panel (1) by means of a lifting frame (7, 8) suspended in a crane hook (2). The concrete panel (1) is removed from the form (3) in a mainly vertical position by means of a cantilever foot or feet (5), and is steadied against the frame by a claw on a swivel arm (6). Since the panel is lifted from the bottom, rather than being pulled from the top, the concrete does not need a great tensile strength, and the hardening time is reduced, as the compressive strength of newly poured concrete is considerably greater than the tensile strength. <IMAGE>

Title: Printing mechanism having a rotatable printing disc
IPC: B41J1/30
Filed: 1981-09-21
Abstract: An angular locking of a printing disc (not shown) is effected by paws (8,9) blocking a toothed wheel (6) angularly secured to the disc. The two pawls (8, 9) are spaced apart from each other by an angle corresponding to a whole number of teeth of the wheel (6) corrected by a half tooth so as to each ensure the locking of the disc (5) in the half of the stop positions. The number of stop positions of the disc, which corresponds to the number of type characters carried, equals the product of the number of teeth on the wheel (6) and the number of pawls (8,9). <IMAGE>

Title: Laminated material
Inventor: NILSSON BENGT GUNNAR
IPC: B32B27/10
Filed: 1982-12-23
Abstract: A laminated packing material with a sterile surface which is protected by a protective layer joined detachably to it. On rolling-up of the the material web to a roll after its manufacture the turns forming the roll are joined to one another by means of an adhesive, which means that the roll will be wholly "tight" and consequently simple to handle during transport and storage without any danger or infection. When the laminate web is to be converted to packing containers, the turns forming the roll are separated from one another between the protective layer and the sterile surface on unwinding so that the unwound material obtains two outer sterile surfaces. <IMAGE>

Title: Improvements in grinding control method and apparatus
Inventor: SMITH RODERICK LOWE
IPC: B24B47/20
Filed: 1984-03-26
Abstract: Grinding control methods and apparatus pertaining generally to maintaining the shape and sharpness of a grinding wheel 20, despite the tendency of the wheel face to deteriorate from the desired shape and sharpness, as grinding of a given workpiece 24 or a succession of workpieces proceeds. Generally, as a common denominator of the features disclosed a "conditioning element" 50 is brought into rubbing contact with the face of the grinding element under specially controlled and unique conditions to (i) restore the desired shape (conventionally called truing), or (ii) to establish the desired degree of sharpness (conventionally called "dressing"), or to accomplish both (i) and (ii) simultaneously. The methods and apparatus disclosed include creating the aforesaid controlled rubbing contact simultaneously while grinding is occurring, and the disclosed inventive features involve truing of wheel faces in a fast, economical fashion by controlling relative surface speeds and feeds of the wheel and the conditioning element, and workpiece size control (despite wheel wear reduction in wheel radius) by gage sensing the conditioning element rather than the workpiece. <IMAGE>

Title: Inserting electronic components into printed circuit boards
Inventor: SCRANTOM DEHART G
IPC: B22C9/22
Filed: 1984-06-27
Abstract: Axial lead components such as capacitors and resistors are inserted into printed circuit boards mounted in an X-Y PC board positioning device. A plurality of magazines 100 each of which contain a multiplicity of the components are loaded into a receiver chute 164 of the apparatus. The apparatus functions, responsive to a signal from the PC positioning device, to remove an individual component from a magazine and direct it to an inserter device. This has tines 44 to deflect the leads to a position at right angles to the body of the component which is held in an anvil 60. The anvil is then pivoted to one side and the thus formed leads are accurately inserted into spaced apertures of the PC board which have been manuvered by the X-Y apparatus to a component receiver station. Means automatically remove exhausted magazines and replace the same with filled magazines. <IMAGE>

Filed: 1984-10-10
Abstract: Method of making a laminate wherein an amide or crystalline polyester fabric or mat is impregnated with a resinous epoxy or polyimide resin. Microcracks which form in the laminate as a result of thermal cycling, are reduced by subjecting the fabric or mat, prior to impregnation, to an active oxygen- or nitrogen-containing gas plasma for from 1 to 40 minutes at an RF power to flow rate ratio of from 1 to 4, a gas pressure of from 0.1 to 5 mm, and a frequency of from 100 Hz to 1 GHz. <IMAGE>
Patent GB-848950-A (GB)
Abstract: 848,950. Lighting burners. BRITISH THERMOSTAT CO. Ltd. April 20, 1959 [April 18, 1958], No. 12390/58. Class 75(3). An ignition device, intended for lighting the pilot flame of a gas burner of the type having a thermally sensitive member controlling the flow of fuel to the main flame, comprises a pivoted lever-operable by a pull rod or cord to rotate an abrasive wheel against a flint-with one end of the lever forming a target against which the pilot flame impinges and serving, when the lever is in its extreme operated position, to deflect the pilot flame on to the thermally sensitive member. In the form shown, the lever 9 is in its inoperative position with its target end 12 holding down the member 18 to close a valve supplying fuel to the pilot flame which, when the valve is opened, emerges from the upper end of the bore 24. When the lever is operated to rotate the wheel 3 to strike sparks from the flint 1, the target 12 moves through an intermediate position-in which it helps to concentrate the flow of fuel, released by the valve opening, to the region of the sparks and also to stimulate air flow into this region to assist ignition-into the fully operated position in which the pilot flame is deflected by the target to heat the thermally sensitive element 8, Fig. 1 (not shown). Interconnection of the pilot flame fuel passage with those of the main burner and source of supply is achieved by a " banjo " type connection 17. In an alternative embodiment, Figs. 3 and 4 (not shown), the pilot flame emerges from a tube 4 situated beside but in communication with a valve 5 supplying it with fuel, these two members serving the same purpose as the single member 18 of the embodiment shown

Each stage includes means for scaling the output of each cell in the stage by a scaling factor calculated from the weighting factor deriving means of the stage.

Title: Antenna
Inventor: GIBSON PETER JOHN
IPC: H01Q19/08
Filed: 1985-02-24
Abstract: In order to improve its return loss, an antenna (1) having a radiating aperture (4) providing a broad E-plane beamwidth (particularly an H-plane sectoral horn antenna) is provided with inductive shunt susceptance at its aperture (4), suitably in the form of a plurality of narrow conductors (14) spaced along the aperture (4) and extending across the aperture (4) parallel to the E-plane.

Title: Process and apparatus for suction extraction particularly for use in the production of aluminium
Inventor: DUPRAT GEORGES
IPC: C25C3/22
Filed: 1985-05-01
Abstract: A process for automatically going into the mode for increased suction extraction of the gases emitted by the tanks of series for the production of aluminium by igneous electrolysis using the Hall-Heroult process, each tank being closed around its periphery by a plurality of removable covers which are disposed in substantially sealed relationship with each other and between each thereof and their support means on the periphery of the tank, the gases being collected over each tank by at least one duct connected to a centralized suction extraction system. The temperature of the gases in the duct is continuously measured. Opening of at least one cover gives rise to an abrupt drop in temperature, which makes it possible to put the system into the increased suction extraction mode, which will be automatically stopped when, all the covers being closed again, the temperature of the gases will substantially resume its initial value. The power required for the suction system is thus substantially reduced.
