Patent GB-2078403-A (GB)
Title: Automatic control of feed of biscuit dough
IPC: A23G3/02
Filed: 1981-05-22
Abstract: The feed of a sheet 1 of biscuit dough via gauge rollers 2, 3 to cutting apparatus is automatically adjusted to compensate variations in the thickness of the sheet emerging from the gauge rollers. The power consumed by or the torque applied to an electrical drive unit 18 driving the gauge rollers is measured, eg. by a current sensor 20, to produce an electrical signal proportional to the power or torque. The signal is compared with a set value and used to adjust the feed of the sheet by varying the speed of the feed rollers. <IMAGE>

Title: Roll tail sealing machine
IPC: B65H19/29
Filed: 1980-01-04
Abstract: The loose tail end (31) of a wound sheet roll is partially unwound by blowers (14) during rotation of the roll in the rewinding direction by supporting rollers. The unwound loose tail end settles on a delivery table (2) for the application of glue to secure the tail end. A first sensor detects the unwinding of the tail end off the roll and activates a normally deactivated second sensor which turns off the rollers when the tail end reaches a predetermined location on the delivery table. Adhesive is next applied to the stationary tail end by a glue gun (15) which is movably mounted on a pneumatically controlled carriage assembly. The glued tail end is thereafter rewound upon the roll, and the roll is subsequently ejected from the machine. A third sensor detects the initial presence of the roll upon the rollers and will initiate ejection of the roll after a predetermined time period elapses, regardless of operation of the glue gun. <IMAGE>

Title: Air intakes
Inventor: HAUTON IVAN
IPC: B60K11/08
Filed: 1981-10-15
Abstract: An air intake for agricultural tractors, combine harvesters and other non-vehicular equipment comprises a box-like housing 22 shaped and proportioned to fit in front of the tractor radiator grill. The housing 22 is entirely closed apart from the top and rear sides which provide air intake and air outlet openings. Thus air for the tractors engine cooling system is drawn through the air intake 44 in the direction of arrow A and thence through the radiator grill and the radiator itself in the direction of arrows B. Intake 44 faces upwardly and is at the level of the top of the engine housing. In use, very little ash or chaff is drawn into intake 44. The reason for this may be the production of a countercurrent arising from the bottom wall 30 of the housing 22. The housing is a sheet metal fabrication and very simple and inexpensive to manufacture. The housing may have a pivotable front wall. <IMAGE>

Title: Oscillator circuits
Inventor: JONES PETER GRAHAM ADPAR
IPC: H03L7/083
Filed: 1982-01-05
Abstract: An oscillator circuit in which a reference signal (REF), at the frequency of an externally applied input signal VS, is injected at one input terminal (7) of a voltage controlled oscillator (10). The VCO is locked to that frequency. The phase of the output (O/P) of the VCO is compared at circuit (30) with that of the reference signal and the charge on a capacitor (C) is varied as a result of that comparison thereby to vary a phase difference. The reference signal is applied via a variable attenuator (14) which is used to reduce the magnitude of the injected signal, while the frequency of the reference signal is maintained within the locking range of the VCO. A coarse tune circuit 20 includes a frequency discriminator 21 and FET 23 forming with capacitor C a sample-and-hold circuit. The phase- control loop comprises a fine tune circuit 30. <IMAGE>

IPC: H01L21/306
Filed: 1982-12-15
Abstract: A silicon etch process wherein an area of silicon crystal surface is passivated by radiation damage and non-planar structure produced by subsequent anisotropic etching. The surface may be passivated by exposure to an energetic particle flux - for example an ion beam from an arsenic, boron, phosphorus, silicon or hydrogen source, or an electron beam. Radiation damage may be used for pattern definition and/or as an etch stop. Ethylenediamine pyrocatechol or aqueous potassium hydroxide anisotropic etchants may be used. The radiation damage may be removed after etching by thermal annealing.

Patent GB-2115244-A (GB)
Title: Power supply means comprising impedance device for saving energy
Inventor: ELLIS GORDON HENRY
IPC: H02M5/12
Filed: 1983-02-17
Abstract: A first coil 20 is installed in a power line leading from an A.C. source to a load 14. A second coil 24 is inductively coupled to the first, and connected so that the induced EMF acts to increase the load current. Thus the current drawn from the source is reduced owing to the inductive load 20, but the energy lost thereby is largely recovered by the second coil. The assembly thus acts as a nearly lossless impedance. The first coil may have a plurality of taps 30 so that its inductance is variable. Thus fluorescent lights can be run with a voltage adjusted to be just sufficient to preserve ionisation, whereby much power is saved for a very small loss in illumination. The load 14 may alternatively be an incandescent lamp or an electric motor. <IMAGE>

Patent GB-2120492-A (GB)
Title: Apparatus for sensing the direction of a source of radiation of unknown frequency
Inventor: GRATZE STEPHEN CECIL
IPC: G01S3/46
Filed: 1983-04-20
Abstract: The invention uses acousto-optic techniques to find the direction of a radiation source of unknown frequency, e.g. a jammer. The radiation is incident on antenna elements 1 which transmit signals to electro-acoustic transducers 2 which launch acoustic waves, having a direction frequency and power dependent on the direction, frequency and power of the source, into a lithium niobate block 3, where they interact with a beam 5 of white light at 6 to deflect the beam 5. By measuring the amount of deflection with detector arrays 11 and 13 having different spectral responses, the direction of the source is determined. The frequency of the source is determined by comparing in circuit 14, 15 and 16 the outputs of corresponding detectors of the arrays 11 and 13. A level sensor 17 indicates the power of the source. <IMAGE>
