Title: Improvements in or relating to locks
Inventor: KEARNEY THOMAS JOSEPH
IPC: G11B33/00
Filed: 1984-11-06
Abstract: A locking device for preventing theft or unauthorised use of a sound or video cassette player and/or recorder comprises a cassette member (10) configured to fit within the conventional cassette holder or carriage (11) of the player/recorder. Disposed within or carried by cassette member (10) is locking means (18) arranged to engage within the player/recorder to prevent unauthorised withdrawal of the cassette member. With the cassette member so locked, the player/recorder cannot be used since a sound or video cassette cannot be inserted until member (10) has been removed. Removal of the cassette member without an appropriate release means, such as key (15) cannot be achieved without damage to the player/recorder, thereby rendering it unfit for resale or use. Cover 12 prevents removal of recorder from a car dashboard. Alternative embodiments are described (e.g. Figs. 2 to 6). An alarm may respond to movement of the recorder, or of the cassette member. <IMAGE>

Title: Methods of authorising actions
Inventor: CROFT ROBERT ALAN
IPC: G07F7/10
Filed: 1985-02-19
Abstract: The invention relates to methods whereby a recipient station, on receipt of messages from a plurality of authorising stations, is enabled to perform an action. Each of the authorising stations possesses one or more address numbers referred to as X numbers, and the recipient station possesses either no address number or one or more address numbers X. Each of the authorising stations is supplied with secret information which is used to transmit messages to the recipient station using a trap-door code technique. The recipient station analyses the messages received to calculate two numbers which need to meet known criteria for a transaction to be authorised. Galois field techniques are used. One application of the present invention is in the transfer of funds between bank accounts.

Title: Optical communications and missile guidance systems
Inventor: BARTON ARTHUR EDWARD MCKENZIE
IPC: H04B10/00
Filed: 1985-05-03
Abstract: Information transmitting method using a laser beam projector which forms part of an optical missile guidance system on board a ship say. For transmitting information to another ship the same beam projector 4 is used to scan a field containing a detector 7 on board the other ship so that the detector receives successive glimpses of the beam at times dependent on the information to be transmitted. Alternatively, after acquisition of the detector in this way, the projector can be aligned by feedback and the beam modulated using conventional amplitude or pulse modulation. The specification also discloses developments of the missile guidance systems described in GB applications 2113939A and 2133652A for example blanking of the projector beam as it is scanned over the target to prevent detection of the projector source by the enemy target. <IMAGE>

Patent GB-2160276-A (GB)
Title: Vehicular hydraulic servo brake
Inventor: REINARTZ HANS-DIETER
IPC: B60T8/96
Filed: 1985-06-05
Abstract: A hydraulic servo brake has a master cylinder (12) and a master piston (11) operated by a pedal (26). Between the brake pedal and the master piston a brake valve (19) is arranged which, upon actuation by the brake pedal applies pressure medium supplied by a hydraulic pump (22), connected to a supply reservoir, to the master piston (11) and makes a controlled pressure available there. A control system 25 automatically reduces the braking force on development of a skid condition. Between two axially staggered gaskets (18, 47) and between the master piston and the master cylinder, an annular supply chamber (13) is provided which is connected to the supply reservoir and in which a supply line (29) is ending. Separated by only an axially narrow annular land (17), a second annular pressure chamber (20) is provided which is connected to the pump (22) via connection bore (21) and to the pressure inlet (24) of the brake valve (19) via a pressure bore (23) in the master piston (11). A pressure switch (16) is arranged to be in communication with a hole (15) in the cylinder wall in such a position as to normally be open to chamber (13), but on excessive piston travel such as may be caused by failure of part of the system the land (17) overrides hole (15) thus exposing the switch to the pressure chamber (20) and shuts off the skid control system. <IMAGE>

Title: Orbital reciprocating engine
Inventor: RUSSELL SIDNEY HUGH
IPC: F02B57/06
Filed: 1986-06-16
Abstract: An eccentrically supported radial housing 2 in which cylinders 8, 9 are to accommodate opposed rigidly interconnected pistons 3, Fig. 2 is constrained to orbital motion round a shaft 15 rotatably supported in an enclosing outer casing 1. The pistons are supported on eccentrics 4 integral with the shaft 15, so as to follow an opposite orbital path to that of the housing 2 on rotation of the shaft 15, with consequent reciprocation of pistons 3 and cylinders 8, 9 and neutralizing of relative movement between them at right angles to the direction of reciprocation. Pistons are prevented from driving housing, by driving it from an orbiting member round eccentrics integral with shaft. Cavities are formed both inward and outward of the pistons with charge transfer between cylinders. Injectors 20 are set in the housing and supply fuel to initial combustion chambers that also act as exhaust ports 14 when not opened by orbital path of housing relative to outer casing. <IMAGE>
Patent GB-2192104-A (GB)
Title: Superheterodyne radio receiver
Inventor: THORN SIMON RICHARD
IPC: H03D7/16
Filed: 1986-06-27
Abstract: A modulated input signal of nominal carrier frequency fc received on an aerial 1 is converted to base-band at an output terminal 5 by a mixer 3 also fed from a local oscillator 8. If the mixer consisted of a single mixer stage the local oscillator output frequency would have to be fc, with the result that leakage of this signal to the aerial 1 would result in this being treated as part of the input signal and hence in an unwanted and unpredictable d.c. component at the output terminal 5. Accordingly the conversion is effected by two mixer stages 6,7 in cascade, the local oscillator frequencies f1 and f2 fed to these two stages both lying outside the pass-band of an input filter 4 and satisfying the relation ¦fc +/- f1¦ = f2 +/- delta, where delta lies within the frequency range from zero to half the receiver reception bandwidth as defined by a base-band pass filter 46 included between the mixer output 47 and the output terminal 5. A transistor circuit (Fig. 2) is described for the mixers 6 and 7. The received signal may be an FSK signal. In a modification (Fig. 3) a third mixer (7A) is fed with the output from mixer 6 and with the output of the oscillator 10 via a 90 DEG  phase shifter (42). <IMAGE>

Title: Sensing a parameter by means of radiation attenuation

Filed: 1986-12-18
Abstract: A parameter of a medium e.g. sheet thickness, density, moisture content, fill level or presence/absence is measured by attenuation of radiation as a function of the parameter upon passage through the medium. Transmitted radiation is detected by a scintillation probe 20 for producing an electrical current output 24, a current integrator 28 for continuously integrating the current output and producing an output signal 43, a charge injector 30 for supplying to the input of the current integrator at 38 current pulses of predetermined total charge and of opposite polarity relative to the output of the probe 20 in response to the output signal 43 reaching a predetermined threshold set in comparator 29, and output circuitry 70, 80, 31 for generating count signals at the frequency at which the current pulses are supplied by the charge injector. Accordingly the current output of the probe 20 is measured even during the duration of the current pulses i.e. there is no dead line. <IMAGE>
