Abstract: 829,191. Oscillating electric motors. HELD, S. Aug. 21, 1956 [Aug. 23, 1955], No. 25581/56. Class 35. [ALso in Group XVIII] In an electric timepiece the going train is driven by a balance which is maintained in oscillation by the interaction between a magnetic field or fields and a current carrying coil or coils, the circuit of which is periodically closed as the balance swings. In principle the coil 1 may be wound into a figure-of-eight, Fig. 1, but in practice two coils of generally triangular shape are used, Fig. 3. The coils are carried by the balance staff and the magnetic fields are provided either by two opposed permanent magnets 3, Fig. 1, or by one permanent magnet and an opposed plate of soft iron. The number of magnetic fields may be increased by arranging additional permanent magnets 5, as shown in dotted lines in Fig. 3. Temperature compensation may be obtained by placing a bar of alloy at its Curie point on the magnet 3. The magnetic fields may be obtained by cylindrical magnets, Fig. 8, or by a magnet of washer form 5, Fig. 9, to which soft iron plates 13, 14 are fixed. The coil circuit contains a switch comprising a flexible contact and a contact carried by the balance. In another example, Fig. 11, a coil 26 oscillates with the balance staff to produce a retarding couple for regulating the amplitude of swing of the balance. The coil may be connected to the input of a semi-conductor amplifier, the output of which is connected to the coils. The coils 1 may be fixed and the magnet or magnets 3 movable, Figs. 14 and 16.

Title: Improvements relating to hoods for tractors or other vehicles
IPC: B62D33/06
Filed: 1957-08-16
Abstract: 866,915. Tractor hoods. FRITZMEIER, G. Aug. 16, 1957 [Aug. 17, 1956; July 22, 1957], No. 26009/57. Class 108(1). A tractor hood is carried on two supports, and the position of the roof can be varied by pivoting it about a horizontal axis and the roof can be fixed in the particular position desired. The hood 1 is carried on two supports each comprising three parts 2, 3, and 4 the upper and lower parts 2 and 4 fitting telescopically on to cranked part 3, each part being relatively rotatable to another, rotation of part 3 adjusting the position of the hood 1 laterally above the driving seat of the tractor. The supports may be locked in a desired position by, bolts 8 which pass through parts 2 and 4 and engage threaded bores at each end of the cranked portion 3. An arm 6 formed from a length of bent tube is welded to each side of frame 5 of the hood each arm being secured to a support by a clamp. Each clamp comprises a, resilient disc 8 held between discs 7 and 9 which are welded to the arm 6 and the part 2 of the hood supports respectively, a clamping screw 12 tensioning each clamp when it is desired to lock the hood in a given position. The lower part of the supports may be formed as a parallelogram movable on itself to give a resilient mounting for the hood, rubber bushes being used with the pivot pins between part 4 of the support, links 30 and the upright 31, to increase the resilience provided by helical spring 32. In an alternative arrangement, the hood is supported by two tubes 25, mounted, on the same side of the vehicle, parallel to each other, the upper portions or arms 26 extending transversely over the vehicle. Sleeves 27 which slide on each arm 26 are joined by bridge piece 31, to which a further horizontal transverse shaft 32 is welded. A bearing bush 33 rotatably mounted on shaft 32 allows the hood to be pivoted about a transverse axis for adjustment, while a further bush 34 welded on bush 33 allows the hood to pivot around a longitudinal axis, shaft 35 which is secured to the frame of the hood, being slidable and rotatable in the bush 34. Stops 28, 29 and 37, 38 control the sliding movement of the hood and clamping screws 42, 44, and 43 secure the hood in any desired position. Specification 779,637 is referred to.

Title: Improvements in direction finders
IPC: G01S3/52
Filed: 1945-10-05
Abstract: 624,563. Radio direction-finding. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 5, 1945, No. 26044. Convention date, May 29, 1943. Addition to 622,822, [Class 40 (vii)] In a system similar to that in the parent Specification in which an aerial is continuously rotated in a closed circular path, whereby signals picked up are phase-modulated at the frequency of rotation, the phase-modulated wave is compared with an unmodulated wave of the same frequency in a phase-discriminating servo system which effects an alternating or swinging control. The frequency of this control is that of the rotation of the aerial, whilst its phase depends upon the direction in azimuth of the arriving wave and its magnitude on the elevation of the arriving wave. This control is employed to vary a standard voltage, the variation being measurable to indicate elevation. The phase of the varying voltage is finally compared with that of a reference alternation of frequency equal to that of the aerial rotation. As shown, an automatic frequency-control system 23 of the kind described in the parent Specification, feeds a phase-modulated R.F. output to a mixer 43 and an unmodulated R.F. output of the same carrier frequency to a similar mixer 45, the two mixers also receiving energy from a common local oscillator 47 and producing outputs at a suitable intermediate frequency which are fed through filters 44 and 46 to a phase-responsive servo system 49. This system includes a motor which is driven in a direction dependent upon the instantaneous difference between the two inputs of the system 49. The shaft 51 of the motor is coupled to a voltage control regulator 53, e.g. a variable mutual inductance regulator, to which constant voltage A.C. energy, e.g. the usual power supply, is also fed. The output of the device 53, which is in effect modulated by the modulation envelope due to aerial rotation, is fed through a rectifier 55 with an associated filter to one input of a second phase-responsive servo system 57. The reference alternation of aerialrotation frequency derived from a generator 59 is also fed to the servo system 57. This servo system includes a motor operated in a manner similar to that of the first servo system 49 and controlling an azimuth indicator 63. The phase-responsive servo systems 49, 57 are similar to the phase-comparator arrangements described in the parent Specification. Specification 592,570 is referred to.

Title: Improvements relating to electrical switching circuits
Inventor: ANSELL RICHARD SYDNEY
IPC: G05D16/20
Filed: 1960-07-27
Abstract: 929,091. Automatic pressure control. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 18, 1961 [July 27, 1960], No. 26144/60. Class 38 (4). In a switching system a resistor, responsive to the pressure of a surrounding gas, is arranged in a bridge circuit the output of which energizes a polarised relay to actuate first contacts closing a circuit breaker if the pressure is excessive in one sense, or to actuate second contacts opening the circuit breaker if the pressure is excessive in the opposite sense. In Fig. 1 a Pirani gauge resistor 2 responsive to the pressure in an evacuated chamber is arranged in a D.C. bridge circuit 1 the output of which operates a polarised relay 8, if the pressure rises beyond a limit determined by the setting of a rheostat 7, so that a relay 13 is energized to close a circuit breaker 23 and thereby switch on a three-phase motor 22 driving a pump (not shown) evacuating the chamber. Evacuation continues until the pressure is reduced below a predetermined limit at which relay 8 operates in the opposite sense so that a relay 14 is energized to interrupt a holding circuit of circuit breaker 23 and stop the pump until the pressure rises again. Energization of a solenoid 19 while the pump is operating opens a valve, between the pump and the chamber, which closes when the pump stops and a connection made between the pump and atmosphere so that oil is not drawn from the pump into the chamber.
