Patent GB-878891-A (GB)
Abstract: 878,891. Gyroscopic apparatus. SPERRY GYROSCOPE CO. Ltd. Aug. 21, 1959 [Aug. 26, 1958], No. 27373/58. Class 97(3) A caging apparatus is shown applied to a gyrovertical in which the rotor bearing case 7 is pivoted about an inner axis 8 in a gimbal 3 which pivots about an outer axis 4 at right angles to axis 8. A member 9 is slidable to the left (Fig. 1) by an electric motor, not shown, in a chamber 16 and urged to the right by a return spring, not shown, so that when the motor is energized the gyrovertical is free but when it is de-energized the return spring slides member 9 to the right to cage the gyrovertical. This causes a serrated edge 18 to engage a knife edge 19 on a member 10 which is pivoted to the gimbal 3 about an axis 11  parallel to axis 8. A roller 20 on the opposite end of member 10 is pressed against a cam 12, fixed to the case 7, so that case 7 is rotated until the roller 20 enters a central slot 13 in the cam 12. This causes a slight pivoting of the member 10, so that knife edge 19 is disengaged from serrated edge 18 and a roller 22 on member 10 thereupon contacts a cam surface 21 on member 9 causing member 10, and therefore gimbal 3, to be rotated about the axis 4 until they are centred and roller 22 and knife edge 19 enter slots 23, 24 respectively. In a modification the electric motor urges the member 9 towards the right, Fig. 1, and the return spring tends to return the member 9 to the uncaged position. In a further form the member 9 which is circular, instead of semi-circular, is mounted outside the gimbal 3, the slot 24 is omitted and slot 23 and roller 22 are of such dimensions that the roller only partly enters the slot to lock the gimbal 3 about the axis 4.

Title: Dual-cure dental cement
Inventor: WALTON IAN GEOFFREY
IPC: A61K6/00
Filed: 1988-01-28
Abstract: A dual-cure dental cement comprises a first component comprising an ethylenically polymerisable compound which contains both a salicylate group and at least one acrylate, alkacrylate, acrylamide or alkacrylamide group; a second component comprising calcium hydroxide or a suitable precursor (e.g. calcium oxide); and a photosensitive catalyst which may be present in either or both of the two components. The cement possesses both calcium hydroxide cement characteristics and light cure characteristics and hence strong bonds are likely to form with both the tooth and conventional filling materials. There is thus less likelihood that a filling may fall out of a cavity.

Patent GB-2205452-A (GB)
Title: Electrical machine
Inventor: SPOONER EDWARD
IPC: H02K41/06
Filed: 1987-01-20
Abstract: An electrical machine comprising a member (3) of magnetic material, and a stator (1) supporting windings which when energised generate magnetic fields in a gap defined between the member (3) and the stator (1). The stator (1) supports at least two windings each of which is energisable to generate a different number of magnetic pole pairs from the other winding or windings. At least one winding comprises a plurality of subwindings arranged to be energised by respective phases of a polyphase current so as to generate a moving magnetic field in the gap. A resultant magnetic field appears in the gap which is a moving magnetic field that is the sum of the magnetic fields resulting from energisation of each of the windings. The resultant distribution of attractive force between the two members (1, 3) may have a long wavelength compared to the winding pole pitches, which is of value in harmonic drive type devices, or may rotate at twice the angular frequency of a supply current, which enables high speed operation.

Title: Digital signal processors
Inventor: PARSONS ROBERT
IPC: H04L7/04
Filed: 1988-09-20
Abstract: A digital signal processor is described for receiving teletext signals from a television signal and for producing from them signals for producing a display of the teletext information. The processor includes a switched comparator 2 (Fig 2) for deriving binary values from an input signal at a frequency eight times that of the bit rate of the input signal. The binary values furthest from the transitions between the bits of the input signals are selected at 7 to form the reproduced bits of the input signal. The input signal is also applied to a synchronising signal separator circuit using another comparator an output of which is used to change the threshold level of that comparator so as to provide hysteresis and reduce the sensitivity of the circuit to noise in the input signal. <IMAGE>
Patent GB-2217535-A (GB)
Title: Digital circuit arrangement
Inventor: GARDNER BRIAN R
IPC: H03L7/081
Filed: 1988-12-12
Abstract: In a digital circuit arrangement, one output of an adder 5 is fed back to an input of the adder via a digital filter 14 so that the variation of the difference between a further output M i.e. a sequence of low precision numbers and the input F has a predetermined spectral response related to the transfer function G(2). The signal M varies in a cyclic manner so that its average value is a low precision representation of the value of F. The digital circuit may be used to cyclically vary the division ratio of a loop divider 22 of a "fractional N" frequency synthesiser in dependence upon a digital control signal F so that the division ratio and the loop output frequency can be controlled in fine increments. Phase jitter due to this cyclic variation may be reduced by inclusion of a controllable phase modulator, 32. A number of digital circuits may be cascaded prior to control of divider 22. <IMAGE>
