Title: Coin collecting apparatus
Inventor: ALLWOOD PETER HENRY
IPC: H04M17/02
Filed: 1982-08-13
Abstract: A coil collecting box for insertion between a subscriber's telephone instrument (1) and a line (2,2') to a telephone exchange includes a coin, token or credit card validator (7) and a dial pulse detector (9) which provide respective signals to a control circuit (8) which may be a microprocessor. The control circuit (8) determines from the digits dialled and the output of validator (7) whether the call is permitted. if the call is not permitted, for instance a call to the operator, the control (8) causes a switch (5) to interrupt the connection to the line (2). A key operated switch (15) provides signals to the control circuit (8) which cause that circuit to permit any calls from the associated telephone (1). The microprocessor may have access to data stores in order to compute the charging rate for long distance calls. A generator 14 feeds tones to the instrument to signal the near exhaustion of credit. <IMAGE>
Patent GB-2106418-A (GB)
Title: Material exchange tray and method of producing it
Inventor: BUHLMANN ULRICH
IPC: B01D3/22
Filed: 1982-09-07
Abstract: A material exchange tray (22) having rigid valves (21) which are formed by covers (25) spaced above openings (23) in the tray (22) and integrally connected therewith by webs (24). Gas inflow slots (26) of the valves (21) are defined between edges (28, 29) of the covers (25) and the edges (23) around openings in the tray (22) which edges are rounded off unlike conventional rigid valves. This yields an increase in gas loading capacity by approx. 30% and a similar reduction in the pressure losses as compared with conventional rigid valves. To produce the tray (22), the covers (25) may be punched out of the tray and the edges of the covers and openings subsequently rounded off by a surface treatment. Preferably, however, no surface treatment is required: The punch is advanced (downwards) only so far as is necessary to shear the tray and the cover is subsequently displaced out of the plane of the tray (22) in the opposite direction (34) so that no sharp edges or burrs occur on those edges bounding the inflow slots. This avoids the need for additional surface treatment. <IMAGE>

Title: Self monitoring system
Inventor: OSHIAGE KATSUNORI
IPC: B60T8/88
Filed: 1982-10-12
Abstract: A self-monitoring system for an automotive electronic control system such as an engine control system, an electronic anti-skid control system or electronic automatic transmission control system is adapted to check each segment of the electronic control system in order to detect faulty segments. To detect faulty segments, the self-monitor system checks inputs and outputs of the electronic control system. The checked data is stored in a memory which is not erased when the power supply is turned off. The self- monitoring system is associated with another automotive microcomputer which includes a display unit. The another automotive microcomputer is adapted to display the results of the checking operation of the self- monitoring system in response to a display request manually inputted from a manual unit to display identification of the fault segment and/or error condition thereof. The monitor can also be associated with a fault indicator, such as an LED, which is responsive to detection of error in any of the segments to turn on. <IMAGE>

Title: Apparatus for controlling production of speech or text
Inventor: GEMMELL DAVID
IPC: G10L13/04
Filed: 1982-10-12
Abstract: To enable a physically severely disabled person to produce messages in the form of speech or printed text, a central processor 29 is provided with a program in a read only memory 34 which includes look-up tables of ASCII codes for a speech synthesizer unit or a printer. The appropriate look-up table is addressed by computing the required address from the coordinates of a selected display element of a LED matrix indicator 19, the selected element displaying a message element chosen by the user by operation of two input switches of input circuitry 45. The program also enables series of coordinates of successive LEDs selected in the matrix indicator 19 to be stored in temporary RAM stores and recalled subsequently as required, with retrieval of corresponding ASCII codes during the recall so that a stored message can be replayed as speech or printed text when required. <IMAGE>

Title: Piston rings
Inventor: BUNCE DEAN S
IPC: F16J9/14
Filed: 1983-03-10
Abstract: A piston ring has a wear-resistant band (38) disposed between two lands (40, 42). The piston ring is split, the division including two oppositely disposed surfaces (52, 70) which are radially and axially inclined and which terminate in one of the lands (40). This construction means that the wear-resistant band (38) terminates at axially extending edges (80, 62) but does not have exposed circumferentially extending edges, which would be prone to damage during manufacture. In one embodiment the band is nearer one edge of the ring than the other and the outer surface of the ring is barrelled assymetrically so that the widest part of the ring is in the centre of the band. <IMAGE>

Title: Cylinder barrel lock security device
Inventor: CRACKNELL PHILIP LEWIS
IPC: E05B29/04
Filed: 1983-05-27
Abstract: The barrel (2) of a conventional rotatable cylinder lock of the sliding multi plate tumbler type is carried in a housing (1) which contains one or more slideable plates (8) positioned to move tangentially to the axis of the barrel. The slideable plate carries a slot into which the tips of the existing tumbler plates protrude. The slideable plate also carries a sprag type projection (10). If an incorrect key or picking tool is introduced into the lock barrel and a rotational load is exerted in order to defeat the lock, the barrel will be slightly rotated, the tips of the tumbler plates within the barrel will urge the slideable plate tangentially, allowing the sprag projection on the plate to co-operate with a recess or cavity (14) in the lock barrel surface, to prevent further rotation. <IMAGE>

Patent GB-2155736-A (GB)
Title: Aircraft position determination
Inventor: RUSH DEREK ANTHONY
IPC: G01S1/08
Filed: 1984-03-08
Abstract: The position of a helicopter (3) (Fig. 1) is maintained constant by means of signals received by a receiver (4) in the helicopter, from a transmitter 1, Fig. 2 on the ground. The transmitter has three orthogonal coils 10, 11 and 12 that are each energised by alternating signals of different frequency so that each coil propagates radiation at a different frequency over a short distance. The receiver also includes three orthogonal coils (40), (41) and (42) (Fig. 3), the radiation propagated by the transmitter 1 inducing a signal at each frequency in each coil. The receiver 4 measures the relative strength of each signal in each coil and from this computes the position of the receiver relative to the transmitter 1. The helicopter is controlled, on change in position, to restore it to its initial position. <IMAGE>

Title: Laser system
Inventor: YESSIK MICHAEL
IPC: H01S3/093
Filed: 1984-09-05
Abstract: A laser system adapted for ophthalmological use includes a closed spherical pump cavity (18) having a diffuse reflecting surface, and a laser crystal (26) and an exciting flashlamp (22) are mounted orthogonally in the cavity. The laser crystal is configured in an unstable resonator by a concave rear mirror and a convex front output mirror. A Q-switch is interposed between the crystal and one of the mirrors. A low power, continuous output, visible light laser is directed through the rear mirror and the laser crystal to provide a pilot beam for aiming and focussing. The laser outputs are both directed from a cantilevered table 59 to a focussing system though a slit lamp biomicroscope 61, and thence into the eye of a patient. The power supply delivers pulses of preselected voltage to the flashlamp singly or sequentially to produce single pulses, bursts of pulses, or repetitive pulses on command. The Q-switch may be operated in synchronism with the flashlamp. The system may be run in a thermal mode in which closely spaced repeated lamp flashes cause the stimulated electron population inversion to be maintained. The resulting long train of pulses within a predetermined time-power envelop closely mimics a continuous beam and produces the thermal physiological effects which are desirable for some laser surgical procedures. The Q-switched mode produces very narrow pulses of high intensity, high beam quality, and precise duration, spacing, and energy. <IMAGE>
