Title: Ignition salary device for gas- fired or oil-fired appliances
IPC: F23N5/10
Filed: 1980-05-01
Abstract: An ignition safety valve for gas- fired or oil-fired appliances which is distinguished by a favourable ratio of solenoid size to closing force has a conventional ignition safety solenoid (45) and a closure member (18) which, decoupled from the armature (47) of the solenoid (45), is seated on a pivoted lever (28) which is acted upon by a closing spring (30). The arrangement is such that the pivoted lever (28) is pivotable with a snapping action between two stable end positions, and, when in one of its end positions, abuts against the valve seat by way of the closure member (18) and, when in its other end position, abuts against the magnet poles (46) of the solenoid (45) by way of the armature (47). The armature (47) has an individual return spring (51) which provides the full closing force in conjunction with the torque which the closing spring (30) exerts upon the pivoted lever (28) when the valve is in its closed position. When the armature (47) is adhering the magnet poles (46), the valve can be arbitrarily closed by a second operating member (53, 54) of the valve which can act upon the pivoted lever (28). <IMAGE>

Title: Device for controlling the hydraulic power-lift for an implement linkage of an agricultural tractor
IPC: A01B63/112
Filed: 1980-05-28
Abstract: The implement linkage of an agricultural tractor (1) has a pair of lower links (2) attached adjacent respective ends of a flexible bar (5) which is connected to a hydraulic power-lift (7, 8) operable in response to flexural deformation of the bar (5) caused by the draft load of an implement hitched to the links (2). The flexural rigidity of the bar (5), and therefore the draft load necessary to operate the power-lift (7, 8), is varied by sliding each link (2) axially on its respective end of the flexible bar (5) and altering the distance between the adjacent bar support (6) and the attachment end (9) of the link (2), a spacer ring (14) retaining the link in its chosen position. The larger the spacing, the lower the rigidity of the bar and the lower the draft load necessary to operate the power-lift. <IMAGE>

Title: Bending sections
IPC: B21D7/06
Filed: 1980-08-29
Abstract: The present invention provides a method of bending a bar in a single plane, e.g. to form a ring by successive bends performed along an L-section 22, such that a simple bend in the required plane would bow the section out of that plane, which method comprises, bending the bar in the required plane and in the same linear press motion bowing the bar out of the plane, in order to compensate for the bow that is induced in the bar by bending in that plane. The invention further provides a set of press tools 15, 16 arranged to bend the bar in two dimensions, upon movement of the tools in one dimension. The method is applicable to bending of an asymmetrical section, or to bending a symmetrical section, e.g. rectangular into a conical ring. <IMAGE>

Patent GB-2064698-A (GB)
Title: Punching or riveting screw fastener
IPC: F16B37/06
Filed: 1980-11-18
Abstract: A punching or riveting bush 2 is fixed in a hole in a sheet 19 by a punching and/or riveting operation in the same way as a punching or riveting nut, but to enable a self- tapping screw to be used, the bush 2 has a rib 12 in its bore 11 instead of the usual internal screw thread and the screw cuts a thread in the rib 12 as it is screwed in. The bush 2 enables a self-tapping screw to be screwed much more securely to the sheet 19 than is possible by the usual technique of screwing the screw directly into an interference hole in the sheet 19 so that the screw cuts a thread in the material of the sheet itself. <IMAGE>

Title: Premixing pilot burner
IPC: F23D14/04
Filed: 1982-03-16
Abstract: The present invention relates to a premixing pilot burner 13 for a gas- fired heat source, such as a gas-fired flow heater, gas-fired closed-circuit heater or boiler or gas stove, the pilot burner has a gas nozzle 23, which blows gas into a mixing tube 16 in order to suck primary air as 26. Prior gas nozzles 23 have been arranged to blow vertically upwardly. But in addition to air, dust enters the region of the gas nozzle through the inlet opening for the air to be sucked and said dust will deposit in that region. Such deposits will change the blowing characteristics of the gas nozzle and will thus change also the gas-air mixture so that such contamination will have a decisive influence on the stability of the burning operation of the pilot burner. That object of the present invention is substantially accomplished in that the outlet end of the nozzle is directed downwardly. <IMAGE>

IPC: B44F1/06
Filed: 1982-04-29
Abstract: A laminated body comprises a substrate, particularly a glass sheet, having at least one pre-printed polyester film bonded to a surface of said substrate. In a particular embodiment the utilisation of a pre-printed polyester film enables plain glass to be utilised instead of figured glass since the bonding of the pre-printed polyester film to the glass sheet ensures that the plain glass complies with safety glass requirements. The provision of printing on the polyester film enables various patterns or pictures to be applied to the glass sheet as well as masking any undesired marks which may occur when bonding the pre-printed polyester film to the glass sheet.

Title: Torque measuring
Inventor: LEAGUE IV JOHN SIMPSON
IPC: G01L3/10
Filed: 1982-09-20
Abstract: Disclosed are a non-contact method and apparatus for measuring the torque of a rotating shaft. Four non-contact proximity magnetic sensors (A, B, C and D) in a horizontal plane are used on the outside of a coupling spacer (32) connecting rotating shafts (20, 22) and having symmetrical dotted patterns (34, 36). Their signals are translated into a measurement of torque. Two of the sensors (A, C) are at one end of the spacer, diametrically opposite each other relative to the centre-line of one shaft (20), and the other two (B, D) are at the other end of the spacer, diametrically opposite each other relative to the centre-line of the other shaft (22). Horizontal and vertical centre-line displacements of the coupling are compensated for without the need of adding corrective signals to or rebiasing sensing circuitry. <IMAGE>
