Patent GB-955261-A (GB)
Abstract: 955,261. Measuring angular rotation electrically; theodolites. CONTINENTAL ELECTROINDUSTRIE A. G., [trading as CONTINENTAL ELEKTROINDUSTRIE A.G. ASKANIA-WERKE]. Aug. 5, 1960 [Aug.12, 1959], No.27236/60. Headings G1F and G1N. A transducer for measuring angular rotation comprises a variable capacitor consisting of two coaxial electrodes, the movable electrode being supported by anti-friction bearings and a spring connection between the fixed electrode and a base, whereby the capacitance is independent of small movements of the electrode support members. The invention is described with reference to a kine theodolite supported with its camera 5 (Fig.2) by members 6, 7 on a base 8 attached to a ring 50 rotatably mounted by ball race 51 on a member 9 whose central position is extended by hubs 9<SP>1</SP>, 52, and cylinder 60 to carry a disc 62, on which is mounted a capacitor electrode 64. The other electrode 73 is mounted on the flange 72 of a hub 71 attached to the base ring 50 by spring arms 82, 84 and a bracket 80, with two ball races 70, 90 located between the hubs 71, 52 and 71, 60. Initial adjustment of the relative positions of electrodes 64, 73 is effected by a worm-wheel (not shown) engaging with teeth 65 on the periphery of disc 62, which drives the member 9, whilst normal rotation of the theodolite and transducer element 64 is produced by a servomotor (not shown) via worm-wheel 55 and teeth 54 on the periphery of hub 52, which drives the ring 50 directly, and electrode 73 through the spring arms 82, 84. The angular rotation is measured electrically by the capacitance between electrodes 64, 73, and recorded by a photograph taken by camera 5 via optical elements 100, 101 of a scale on the edge of element 64. The capacitative coupling may alternatively be an inductive coupling. Specification 952,341 is referred to.

Title: Low-noise charge pump for high-side switch
Inventor: NADD BRUNO C
IPC: H01L29/78
Filed: 1996-04-10
Abstract: The charge-pump in an integrated high-side switch is connected to earth via a current source 53, so that the charge pump floats relative to earth and generates less noise. The Zener clamp 54 across the charge pump allows the use of a low voltage small area pump capacitor 44. The diode 46 may be implemented as a depletion MOST, and the diode 45 as an enhancement MOST. These are easily integrated into the common monolithic IC. The charge pump is connected to the positive supply by a switch 47 which may be implemented as an enhancement vertical power MOST of similar construction to the output MOST 32 (figures 5A and 7), and with the same gate drive potential. The main power device may alternatively be an IGBT or MOS-gated thyristor.

Title: A pulse generator for electric fences
Inventor: BOYS JOHN TALBOT
IPC: H03K17/80
Filed: 1994-10-18
Abstract: A circuit (700) for an electric fence energiser (examples are 6 or 24 Joule versions) which synthesises a pulse having a raised cosine waveforrn at a first or bus voltage uses a ferrite-cored output transformer (701) to multiply the voltage of the pulse to the required level. A raised cosine waveform has a low harmonic content and little filtering of highpower pulses is required in order to minimise electromagnetic emissions. On closure of a switch (707) in series with an inductor (705), a first capacitor bank (703) commerces charging a second smaller capacitor bank (704) in parallel with the output primary, and after the peak of the pulse any remaining charge is dissipated in a resistor (708) with the aid of a saturable inductor (702), acting as a switch. The saturable inductor may be the output transformer itself for lower output energisers. The output exhibits little or any reversal of polarity when matched to its load. The circuit may also be useful for applications such as strobe flashers in aircraft.

Title: Suspension system for a steerable wheel of a vehicle
Inventor: HEWSON PETER
IPC: B60G21/055
Filed: 1996-09-05
Abstract: The vehicle suspension comprises a suspension member 14 pivotally connected at its inner end to a body 16 of the vehicle 10 with a ground engageable wheel 12 carried by a wheel mounting 13 pivotally mounted at its other end. A resilient strut 18 incorporating a damper 20 is arranged between the wheel mounting 13 and the body 16 for controlling movement of the suspension member 14. A link 28 connects an anti-roll bar 30 with the strut 18 such that, during cornering, a transverse force Pr applied to the strut 18 during cornering will be opposed by a transverse force Tr applied to the strut by the anti-roll member 30 along the link 28 to the strut 18. This will reduce the drag that can be created within the strut 18 caused by side loading, and therefore help alleviate a certain amount of harshness created in vehicle ride when cornering.

IPC: H01M4/134
Filed: 1997-11-05
Abstract: Rechargeable generator consisting of an anode of an alkali metal or a malleable alkali alloy, at least one polymer electrolyte which is conductive with respect to alkali cations and act as separator, as well as at least one cathode which is reversible to cations of alkali- metal and its current collector. The anode comprises a thin metallic sheet, less than 100 micrometers thick, which includes at the surface thereof a passivation film. The polymer electrolyte comprises a homogeneous separator which is resistive against mechanical deformation and is capable of transmitting a pressure on the anode to resist against the dendritic strain of the metal of the anode by undergoing an amount of deformation lower than 35% of its thickness. The quality of the ionic exchanges of the interface anode/polymer electrolyte is maintained and finally, the combination anode of alkali metal, separator electrolyte, cathode and collector is maintained under a mechanical strain which is sufficient to ensure that the separator confines the anode sheet in place to preserve the integrity of the lithium-electrolyte interface during consecutive cycles of dissolution/plating.

Abstract: A compliant interface device 1 for use between a manipulator, such as a robot arm, and a tool 2, includes manipulator attachment means having spaced arms 4a, b, an intermediate member 5, compliantly supported between the arms, and counteractive springs 6a-h for providing the compliant support. Anchorage points for the springs are selectively located on the arms (11, figure 2) and intermediate member (10, figure 2) to adjust the compliant response of the device. The geometric arrangement is modelled by computer so as to enable the relative positions of the anchorage points to be adjusted or located to vary the compliant response. This enables linear springs to produce a complex response. Artificial neural networks (ANN) are used for reducing errors, a training period being carried out in which the manipulator is used to move the mechanical model of the compliant interface device through a region of space whilst the tool remains fixed, positions and forces being recorded in order to train the ANN.
