Title: Preventing fraudulent operation of coin-control system
Inventor: STEELE KEITH CHRISTOPHER
IPC: G07F1/04
Filed: 1989-09-13
Abstract: A coin-control system 10 comprises a movable member, eg a rotatable disk 20 having a cavity (28, Fig. 3) in one face for a coin 18, the disk 20 only indexing the cavity from a first position 28a, where it receives the coin 18, to a second position 28b, where the coin 18 falls out of the cavity (28), if a metal-detector 30 which is located. adjacent the first position 28a detects metal in the coin 18. When the coin 18 falls out of the cavity (28) at the second position it falls through a second sensor 32 and into a coin-validator 34 which accepts or rejects the coin. The coin then passes either to a "reject" exit 38 or an "accept" exit 40. Only if the coin 18 is detected as having passed through one or other of these exit openings 38, 40 is the cavity indexed back to the first position 28a thus preventing fraudulent obstruction of exit 38. If sensor 32 does not detect a coin it renders the system inoperable and disc cannot rotate, thus preventing sticky coins from being used. A standby position of the cavity may be provided (28c, Fig. 4), and the cavity may be provided with a radially inner part 28a in which the coin is held during disc rotation. <IMAGE>

Title: ECG signal monitoring
Inventor: CAMM ALAN JOHN
IPC: A61B5/0245
Filed: 1989-11-22
Abstract: For monitoring a signal which comprises successive waveforms, such as a signal from an ECG corresponding to a heart beat, the waveform may be represented by time characteristics such as the length of time spent above an upper reference level (upper rail), the length of time spent below a lower reference level (lower rail), or the length of time taken to fall from one reference level (rail) to another. This representation is compared to a corresponding representation of a reference waveform. The waveform may be sampled and digitised in preparation for processing by a microprocessor. The apparatus is suitable for use in an implantable device such as a heat pacer. <IMAGE>

Title: Fabric smoothing and drying device
Inventor: RIDD PHILLIP JOHN
IPC: D06F34/26
Filed: 1989-11-24
Abstract: Smoothing. A fan 1 in enclosure 9 discharges upwards over a heater in duct 4 to inflate a fabric article to impart an ironed appearance after drying. The article is releasably held by fixed clamps 6.7 and adjustable clamp 8 and supported by adjustable hanger 17 or clips 12 suspended by cord 16. Air escaping past or through the article is recirculated to the fan inlets 58, 59 via openings 10, 11, 39, 40 which create currents in the recirculating air to enhance drying in specific areas. Major discontinuities in the article are sufficiently closed by clips (12, Fig 3,4) or baffle 15 or by causing the abutting fabric to form two close and parallel or overlapping edges held taut. There is a net flow of air through the device inducted via in let 57 and exhausted via outlet 5. Drying. Fabric articles accommodated within a stationary receptacle (Fig 11) releasably located over duct outlet 2 are agitated and dried in the upward air stream. Sections of the device can fold inwards to facilitate storage. <IMAGE>

Title: A drive arrangement for an electrically driven machine
Inventor: SCHNEIDER ARMIN
IPC: H02J3/30
Filed: 1990-02-17
Abstract: An electrically driven machine such as a stamping press has an electric drive motor 24 which drives the machine. The motor is connected to the machine through an assembly 32 comprising a flywheel and a clutch. The operating cycle of the machine includes a working phase and a non-working phase. in the non-working phase, the electric current to the motor is switched off but the rotor of the motor continues to be rotated by the inertia of the flywheel. At the beginning of the next working phase, the electric current is restored to the motor. The clutch is preferably disengaged during the non-working phase so as to disconnect the flywheel from the machine. The switching on and off of the electrical current to the motor may be triggered either mechanically or electronically at pro-set points during each operating cycle. If the machine is in the form of a stamping press, the press may include a movable cross-head (12, Fig. 1) which is raised and lowered during each operating cycle and which occupies an uppermost stationary position during the non-working phase. <IMAGE>

Title: Circuit for synchronous demodulation of the signal from a variable impedance sensor
Inventor: SWADLING ROGER DAVID
IPC: G01D5/20
Filed: 1992-10-02
Abstract: At least one of a pair of impedance elements such as inductors 1a, b is varied in dependence on the position of a movable member. The inductors are connected (with capacitors 2a, b) to drive circuitry 3 to form an oscillator whose peak output voltage varies with the position of the movable member. The oscillator is connected to a timing circuit 6 to produce synchronous trigger pulses 11, 12 which control switches 4,5 so that two samples are taken of the oscillator output spaced equally on each side of the output peak. Any difference in the two samples is fed back to correct the sample timing. The first trigger pulse 11 also controls a further switch 13 to provide the sensor output signal via an amplifier 14, the samples taken by the switch 13 thus being at the instant of minimum current flow in the oscillator. The timing of the sampling is controlled and referenced to the zero crossing of the oscillator signal, and the closed loop sampling of the drive signal may also be used to control the supply voltage to the oscillator circuit. <IMAGE>
