Title: Magnetic, electric signal chopper
Inventor: HILL WALLACE JAMES
IPC: H01H36/00

Abstract: 1,241,943. Selective signalling. TUDOR CONTROL SYSTEMS Ltd. 12 Aug., 1968 [19 May, 1967; 14 June, 1968], Nos. 23273/67 and 28295/68. Heading G4H. [Also in Division H1] A movabe magnet switch for use as a signal chopper in machine tool control has a permanent magnet movable in a direction perpendicular to its magnetic axis into alignment with the magnetic axis of a fixed magnet to operate a magnetic reed contact unit located in a space between adjacent ends of the fixed and movable magnets. The contact units 36c, 37c, 39c are mounted in slots 36, 37, 39 in a raised portion 35 of a non-magnetic housing end plate 18 and respective fixed permanent magnets 36b, 37b 39b in blind holes 36a, 37b, 39b which are perpendicular to the slots 36, 37, 39. The movable magnets 40, 41, 42 are mounted on a non- magnetic disc 26 secured on a shaft 23 rotatable in bearings 21, 22 in a non-magnetic housing 16 sealed by a closure plate 28 and oil-seal 32. In Fig. 5 a similar shaft 123 is driven from a shaft 153 through gears 157, 158 providing a speed increase ratio of 5 to 1 and a movable magnet 160 mounted on a hub 159 of the shaft 153 operates a contact unit 162, to provide a signal at every revolution thereof. The disc 126 carries ten magnets 140 arranged in a circle coaxial with the shaft 123 and at the same radius, the plate 118 accommodates two contacts units 165a, 165b and respective magnets 164a, 164b. As the disc 126 is driven at five times the speed of the shaft 153 its ten magnets co-act with the two contact units 165a, 165b to produce one hundred signal chopping actions in a circuit which has the two contact units or relays controlled thereby in parallel. Contact units 137c are operated by a single magnet 141 to produce ten operations per revolution of the shaft 153. Other sets of gears may be driven from the shaft 153 (Figs. 9 and 10, not shown) and magnets carried thereby may control contact units so that a circuit is only completed at one position or at accurately spaced positions of the shaft (Fig. 11, not shown). The phases in the circuits of the contact units can be used to operate a numerical indicator (Fig. 12, not shown). The fixed magnets may be electromagnets and the movable magnets may be remanant member which moves past permanent or electro-mangets during their movement.

Title: Wheel slip detector for use in anti-lock vehicle brake systems
IPC: B60T8/70
Filed: 1972-06-19
Abstract: 1410992 Anti-skid control MULLARD Ltd 19 June 1973 [19 June 1972] 28587/72 Heading F2F A wheel slip detector circuit for an anti-skid braking system comprises means producing a D.C. signal the amplitude of which is a function of wheel speed, means for establishing a reference rate of change parameter representative of a predetermined wheel deceleration value, and means for determining over a range of wheel speeds, in dependence on the instantaneous amplitude of the D.C. signal, a selected percentage of the instantaneous amplitude (and thus of the actual wheel speed), so as to produce an output for anti-skid control in response to a change in the instantaneous amplitude of the D.C. signal greater than the selected percentage and at a rate of change in excess of the reference rate of change parameter. In Fig. 3, the circuitry comprising resistors R1 to R6, capacitors C1 to C5 diodes D1 to D4, and transistors T1, T2 produces from a wheel speed input, at a coil L of an electromagnetic wheel sensor, comprising a train of pulses, an output fed to a capacitor C6 having an amplitude varying as a logarithmic function of the wheel speed. The combination of the capacitor C6 and resistors R9, R10 provide the reference rate of change parameter since they form a differentiating circuit so that when the voltage at the input side of the capacitor C6 drops below this reference value, transistors T3, T4, normally conductive, are rendered non-conductive, and a non- conductive transistor T5 is rendered conductive providing an output to a solenoid valve for brake release. Spurious high frequency oscillations are prevented by a capacitor C7 and the circuit is made less sensitive to ripple in the signal voltage by a capacitor C8. In Fig. 4, the circuitry comprising resistors R1 to R24, capacitors C1 to C9, diodes D1 to D9, and transistors T1 to T7 produces a signal from the emitter of transistor T7 having a voltage proportional to the wheel speed. This signal is applied to a base of a transistor T8 which, if positive, holds this transistor conductive to hold a transistor T10 conductive. If this signal changes by a negative step, corresponding to a predetermined fraction of a wheel speed change at a rate in excess of the wheel speed change reference rate, a current passing through a transistor 79, coupled to a capacitor C12 and resistors R26, R27, becomes zero. The reference rate is determined by linear decay of voltage across the capacitor C12 discharged by the transistor T9. When this occurs, transistors T8, T10 become non- conductive, producing a signal after phase inversion and amplification to a solenoid valve for brake release. Fig. 5 (not shown), provides a similar circuit to that of Fig. 4.

Title: Improvements in or relating to devices for producing vibrations
IPC: B06B3/00
Filed: 1938-10-03
Abstract: 519,791. Oscillating motors. LIST, H. Oct. 3. 1938, Nos. 28629, 28630; 28631 and 28632. Convention dates, Oct. 1, 1937, May 24, 1938, June 1, 1938, and June 22, 1938. [Class 35] [Also in Group XXIV] A device for producing vibrations comprises two vibratable masses A, B, a power unit to vibrate them in opposition to one another, a resilient coupling between the masses, a relatively fixed structure to which the masses are resiliently coupled by means additional to the resilient coupling between the masses, the coupling between the masses being adjustable for varying the natural-frequency of the device. The power unit comprises action and reaction components connected respectively to the masses and may comprise a hydraulic or pneumatic motor, but in the form shown an electromagnetic motor is employed. The electromagnet 4a together with a frame 6' 'mounted by leaf springs 7 in a fixed structure 7a and constitutes the mass B, while the armature 5 together with a frame 3 and a table 1 adapted to carry articles to be subjected to vibration, is mounted on the fixed structure by leaf springs 20, 21. Leaf springs .17, 18 also connect the armature and magnet to ensure correct relative movement. Alternatively, the spring 7 may secure the mass B to the mass A instead of to the fixed structure. The resilient coupling between the masses is provided by means of springs 12 . . .15 carried by nuts 10, 11 mounted on a screw-threaded shaft 22 journalled on the frame 6. The springs bear against pins 9 carried by a bracket 8 on the frame 3. The surfaces of the nuts facing the springs' are curved so that on rotation of the shaft 22 as by a knob 23 and flexible shaft 24, the effective lengths of the springs and, the period of vibration are altered. The periodicity of the mass A is preferably adjustable to allow for differences in the weights ofarticles placed on the table 1. In order to avoid the transmission of vibrations to the fixed structures, the centre of gravity of the system should remain at rest and for this result to be obtained the ratio of the coupling factors of the resilient couplings between the fixed structure and the masses should be proportional to the ratio of the masses. The resonant frequencies of the individual masses should be substantially above or below that of the system as a whole. The Specification describes with reference to Figs. 2-11 (not shown) examples of leaf springs and their mountings for searing the masses A and B to the fixed structure. The springs may be replaced by double-convex lens-shaped air cushions, the internal pressure of which can be varied, and these cushions cooperate with flat, concave or convex bearing surfaces.

The radii of step and throat end are of different magnitudes. The width 2r 2  of the throat is chosen to suit the yarn in use.
