Title: Waveguide systems utilising the faraday effect
IPC: H03H7/00
Filed: 1953-01-30
Abstract: 731,734. Automatic control systems. STANDARD TELEPHONES & CABLES, Ltd. Jan. 30, 1953 [Feb. 5, 1952], No. 2742/53. Class 38 (4). [Also in Groups XL (a), XL (b) and XL (c)] Apparatus for maintaining in a desired plane the polarization of plane-polarized electromagnetic waves propagated in a lengthy circular wave-guide comprises an element 10 for effecting Faraday rotation of the plane of polarization. The element comprises an evacuated envelope having a cathode 11 and an annular anode 12. The anode is connected to ground and a controllable ionic discharge is maintained by means of a regulable potential on the cathode 11. In an alternative construction the cathode and anode are arranged coaxially and either a D.C. or an R.F. potential maintained across them. In the latter case both electrodes may be outside the envelope. An axial magnetic field is provided by a coil 15 to which A.C. or D.C. current pulses may be applied from a source 8. The amount of rotation of the plane of polarization depends upon the electron density of the discharge and upon the strength of the magnetic field. Linearly polarized waves are launched in the circular guide 47, Fig. 5, from a rectangular guide 45 and pass through a Faraday-effect component 48. The plane of polarization of the waves is monitored by two probes 49, 50 which lie at an angle # to the desired plane of polarization. The probes are connected to detectors 51, 52 which feed a comparator circuit 53. The output of this circuit is a D.C. voltage whose polarity depends upon which of the probes 49, 50 picks up the stronger signal, i.e. depends upon the angle between the plane of polarization and the desired plane. The comparator voltage is fed to an amplifier 54 and the output of this amplifier coupled either to the cathode 11 or the coil 15 in such a manner that the rotation of the plane of polarization is such as to equalize the voltages picked up by the probes 49, 50. Specification 731,362, [Group XL (a)], is referred to.

Filed: 1970-01-21
Abstract: 1299931 Feeding sheets GENERAL FOODS CORP 21 Jan 1970 [30 Jan 1969] 3042/70 Heading B8R In a machine for stacking sheet articles, e.g. cartons C, serially fed thereto, the sheets are fed to a magazine 6, the elevator bottom E of which is intermittently lowered as the sheet stack reaches the height of a sensor, e.g. a finger 54 which is raised by the top sheet of the stack causing a lever (62), Fig. 4 (not shown), to rotate into the path of liight directed from a source (64), Fig. 3 (not shown), to photoelectric cell (66), to accommodate more heets until a pre-determined number have been counted by a counter 5 and/or a stack of a desired height, as sensed by an elevator height detector, has formed when a signal causes separator means, e.g. transversely extending knives K, to extend across the magazine 6 to support the stack formed by subsequently fed sheets, the elevator E then being lowered continuously, as a result of this extension, taking with it the stack below the separator, to a stack discharge position. The sheets may be fed from a cutting press 2 by a fast conveyer to a slow conveyer 4 so that they overlap as they reach the magazine 6 which has reciprocating jogger plates 10 which form a plurality of neat stacks. The stacks are driven from the stack discharge position of the elevator E by pushers P into a turret T which has a vertically movable plate 124 which clamps the stacks against the bottom run of top, stationary conveyer belts 128, the turret T then being rotated to invert the stacks. The plate 124 is then retracted and the stacks transported to a station S by the conveyer belts 128 which now support the stack bottoms and are driven by a friction, e.g. rubber tyre (146) (Fig. 5, not shown) at the end of a belt drive shaft which tyre contacts a rotating belt (176). A conveyer belt 203 in the station S is actuated by a stack sensor 210. The elevator bottom E, consisting of a number of transverse bars 32 and the clamping plate 124, has rack and pinion arrangements to evenly distribute the load. The reciprocating and revolving motors which drive the conveyers, joggers, the elevator, the pusher, clamping plate and turret may be hydraulic, a fluid control system, Fig. 8 (not shown), being actuated in correct sequence and with suitable time delays by an electrical circuit, Fig. 9 (not shown). The motors may alternatively be pneumatic. The intermittent lowering of elevator E may be replaced by more continuous lowering supplemented by intermittent lowering steps.

Title: Improvements in or relating to devices or appliances for the toasting or cooking of bread slices and other edible pieces
IPC: A47J37/08
Filed: 1953-02-04
Abstract: 726,211. Grilling and toasting apparatus. JEFFS, E. F. Feb. 4, 1954 [Feb. 4, 1953], No. 3102/53. Class 28 (1). A gas appliance, for toasting or cooking one or more bread slices or other edible pieces, has a holder for the or each piece which is adapted to receive a piece of any desired thickness, within limits, and has means automatically to centralise such piece between the heating elements by movement of said holder to operative position. As shown, a toaster comprises a base 10 and side supports 12, 12 with lips 13 and brackets 14 which locate heating elements above gas jets 16. The holder for the food to be toasted comprises a base plate 19 carrying posts 20, 20a which support, pivotally, two frames 21, 21a, 23, 23a connected by a link 24. Base plate 19 has a circular portion 19a mounted on a boss 25 having bearing recesses 25a at each end engaged by adjustable pivots 26, 27. Boss 25 is drilled to receive handle rod 31 which passes through an elongated aperture 19b in portion 19a giving free relative movement between handle rod 31 with boss 25 and portion 19a. Secured to boss 25 is an arm 32, e.g. of stout wire, whose free end 32a engages a slot 21b in one frame component 21a. Thus the angular movement of handle 31 and hence boss 25 relative to plate 19 causes the linked frames 21, 21a, 23, 23a to pivot and engage the food so as to hold and centralise it. The pivotal movements of the rectangular frames may be spring-influenced, counter weighted or cam operated. Movement into and out of operative position may be timed automatically, for example a series of holders may be mounted on radial arms to be rotated step by step adjacent heating elements. The holders may be traversed between heating elements by means of an endless belt or conveyer.

Abstract: 1141947 Vehicle washing apparatus A V W EQUIPMENT Ltd 19 Jan 1968 [20 Jan 1967] 3204/67 Headings G3R R9F R1A R1B R24 R33D1 R33D2R R112C R110R and R43 Car washing apparatus comprises a brush 1 rotatable by an electric motor 9, the brush being mounted on carriages 2, 3 connected with chains 6 having fixed therewith over-counterweights 5 tending to move the brush upwardly, the arrangement being such that when the brush comes into contact with a vertical or upwardly directed vehicle surface the torque required to rotate the brush increases calling for an increase in the power consumption of the motor 9, this latter increase being detected above a predetermined value by an overload trip 10, 11, 12 which releases an electromagnetic brake thereby allowing the brush to rise under the influence of the counterweights. In modifications the brush may be given a steady downward movement and when in contact with the vehicle surface above a predetermined pressure, pressure rams or electric motors move the brush upwardly. Instead of measuring the power consumption of the motor 9 alternatively a torque sensing device could be positioned between the motor 9 and the brush causing the brush to be moved away from the vehicle when the torque is greater than a pre-set figure representing the desired contact pressure of the brush with the vehicle. In further modification a tachometer or centrifugal switch could measure the rotational speed of the brush and cause it to move from the vehicle surface whenever this speed fell below a pre-set minimum caused by contact pressure.
