Patent GB-2076997-A (GB)
Title: Control circuit for electric heater elements
IPC: G05D23/24
Filed: 1980-05-30
Abstract: A control circuit for electric heater elements 12, 13 e.g. of a fan heater includes triacs 14, 15 in series with the respective elements 12, 13. A known logic device 16 generates, at its terminal 4, trains of control pulses, the duration of each pulse train being dependent on the amount by which a temperature sensed by a thermistor 17 is less than a desired temperature set led by a resistor 20. The triac 14 is responsive to the pulse trains, and a delay circuit 34, 35, 36, 37 generates a control signal to switch on the triac 15 only after the aforesaid pulse trains have become continuous, which occurs when the difference between the desired and sensed temperatures exceeds a predetermined value. <IMAGE>

Title: Checking the location of moving parts in a machine
IPC: G01S13/88
Filed: 1980-07-29
Abstract: In order to monitor the clearance between turbine blades and the casing of a turbine engine millimetric microwave radiation of wavelength  lambda  is propagated along a waveguide and through an aperture onto the end of a turbine blade. The aperture is small in relation to the area of the blade facing the aperture, and the aperture has a spacing of  lambda /4 or less from the blade. A balanced mixer (3) compares the phase of the wave reflected from the blade with a reference signal to provide a measure of the clearance. Circuits (10 to 19) may be provided for monitoring the spacings between blades, and to indicate blades which are damaged. <IMAGE>

Title: Tank unit for fuel gauge
IPC: G01F23/36
Filed: 1980-09-09
Abstract: A tank unit of the kind including a float carried by a movable float arm for sensing the fuel level, the float arm movement operating an electrical circuit (potentiometer) adapted to provide a varying output signal for a fuel gauge, is predominantly of plastics material and with a main body part 1 formed as a one-piece moulding, said moulding being generally of open box form. One wall 13 has a mounting 19 for the pivotal connection of the float arm A, and an opposite wall 12 is formed with a cut-out 50 through which the assembled float arm passes. One edge 51 of the cut out 50 provides a datum point for indicating one level position of the tank. The arc B through which the float arm A can swing is set by the other edge of the cut-out. The position of this edge, and hence the amount of arc movement, can be varied by cutting away, or nibbling, the wall 12 by an appropriate amount so that the unit is readily adaptable for a wide range of vehicle/tank applications. Preferably the tank unit includes a top plate 2 for fixing the unit in position, and said top plate and main body parts are formed as a one-piece moulding. <IMAGE>

Title: Stackable trolley storage facility
IPC: A47F10/04
Filed: 1980-12-12
Abstract: A storage facility for independently movable and stackable trolleys, e.g. supermarket trolleys, which comprises a gated inlet (31) through which trolleys can be introduced one at a time and a gated outlet (26) through which trolleys can be released one at a time.

Title: Welding current control in resistance welding
IPC: B23K11/25
Filed: 1981-01-15
Abstract: During resistance welding the welding current is caused to rise gradually to a maximum value at which it is held constant.

Title: Outboard drive
IPC: B63H20/08
Filed: 1981-02-18
Abstract: A trim and tilt arrangement for an outboard drive includes an elongated support pivoted at their forward ends on the lower part of the rudder post and at their rearward ends interconnected by a connection which with the aid of elongated slots in both side walls of the outboard drive casing passes therethrough. An engagement in the outboard drive engages from behind the connecting means.

Patent GB-2101057-A (GB)
Title: Connecting lengths of track
Inventor: BONE DEREK IVAN
IPC: E01B25/00
Filed: 1981-07-03
Abstract: A resilient joining piece 5 for connecting two individual lengths of track 1 (e.g. for a mobile gas cutting and welding machine) includes a base 6 and opposed side walls 7. A portion at least of each side wall 7 overlies the base 6 and defines with the base 6 a space for accepting resiliently a side edge 4 of a track 1. The resilient joining piece 5 permits relative movement of the individual track lengths in a vertical plane but prevents or inhibits movement in any other plane and applies a small force for restraining longitudinal separation of the individual track lengths. Since the track lengths need not be machined, joining is simpler and cheaper. <IMAGE>

IPC: H02K53/00
Filed: 1981-09-10
Abstract: Apparatus for converting dynamic energy into electric energy comprises a plurality of trucks (2) which move around a circular track (1). A transmission shaft (5) is located at the center of the circle of the track (1) and passes vertically to an underground chamber in which an electric generator (6) is stored.

Title: Device for Fixing a Bulb on to the Reflector of a Headlamp
IPC: F21V19/00
Filed: 1982-02-08
Abstract: The device incorporates a fixing collar (13) independent of the reflector (1) and capable of being mounted on the latter in two different positions in which, respectively, it provides a support for standardised means (12) on the base (6) of a bulb (4) of differing types.

Title: Removing liquid from strip in a rolling mill
Inventor: ADAIR JAMES RICHARD
IPC: B21B45/02
Filed: 1982-12-10
Abstract: A substantial amount of liquid lubricant used in a cold strip rolling mill is prevented from remaining on the strip by locating an entry guide on the entry side and employing several zoned air nozzles which deliver a positive pressure to force the liquid in a direction toward the centre of the strip, and which nozzles are controlled according to the width of strip being rolled. The relatively small amount of liquid finding its way on to the delivery side is removed from the strip by providing in the strip exit guide both positive and negative air pressure means located above and below the strip, and negatively pressurised longitudinal enclosures located adjacent both edges of the strip and the said area at the ends of the rolls. <IMAGE>
