Patent GB-2108567-A (GB)
Title: Combination lock
Inventor: CHANG FUH YOU
IPC: E05B37/02
Filed: 1981-11-06
Abstract: The invention relates to a combination lock which includes a slide spindle (D) on which spindle sleeves (L) are rotatable by number-rings (R) mounted on and keyed to respective spindle sleeves. When all the number-rings (R), and therefore their associated spindle sleeves (L), are rotated on the slide spindle (D) to correspond to the predetermined set of combination numbers, the spindle sleeves free the slide spindle for axial movement from a locked to an unlocked position. This axial movement is effected by manually sliding a pushbutton (G), connected to the slide spindle, in the axial direction of the latter. The pushbutton (G) has a projection which is guided in an L shaped slot in the face panel (C) of the lock, and slidably cooperates with an inclined slot in a drive plate (J) connected to the slide spindle.   When the combination is to be changed, movement of the pushbutton in a direction perpendicular to the first mentioned axial direction axially displaces the spindle sleeves (L) relative to, and uncouples them from, their respective number-rings (R). A detector for ascertaining a forgotten combination is desired. <IMAGE>

Title: Apparatus and method for unblocking sinks
IPC: E03C1/306
Filed: 1982-02-26
Abstract: Apparatus 1 for use in removing blockages from the waste pipe of a sink 6 comprises an elongate stem 2 for insertion through a drain outlet 7 of the sink 6. The stem 2 has a fluid flow passageway 4 extending therealong and walls 5 capable of bulging outwardly. The passageway 4 is adapted such that flow of fluid therealong is restricted to allow the fluid to cause outward bulging of the walls so as to close an inlet 10 into the waste pipe 8 from the overflow and allow fluid issuing from the passageway to pass into the waste pipe to clear the blockage. <IMAGE>

Title: System for thermochemical hydrogen production
IPC: C01B3/02
Filed: 1982-05-10
Abstract: Method and apparatus for joule boosting a SO3 decomposer using electrical instead of thermal energy to heat the reactants of the high temperature SO3 decomposition step of a thermochemical hydrogen production process driven by a tandem mirror reactor. Joule boosting the decomposer to a sufficiently high temperature from a lower temperature heat source eliminates the need for expensive catalysts and reduces the temperature and consequent materials requirements for the reactor blanket. A particular decomposer design utilizes electrically heated silicon carbide rods, at a temperature of 1250K, to decompose a cross flow of SO3 gas.

Title: Method and device for controlling the tracking
Inventor: TAKEUCHI MOTOHIKO
IPC: G11B15/467
Filed: 1984-03-20
Abstract: In a method and device for controlling the tracking in a playback mode in accordance with at least four pilot signals of different frequencies f1, f2, f3 and f4 which are sequentially recorded together with information signals on tracks of a recording medium in a predetermined cyclic sequence and which satisfy e relationship ¦f1-f2¦ : ¦f2-f3¦ : ¦f3-f4¦ = A:B:A, an extraction (E) section extracts pilot signal components from reproduced signals obtained by playing back the recording medium. A reference signal supplying section (RS) supplies four reference signals which have the same relationship those of the four pilot signal frequencies f1, f2, f3 and f4 and a different cyclic sequence from that of the four pilot signals. A comparing and detecting section (CD) compares the extracted pilot signal components with the corresponding reference signals and detects differences between the two pilot signal components extracted from the right and left tracks adjacent to the reproduced track and the corresponding reference signals so as to obtain two difference frequency signal components which respectively have predetermined constant frequencies in any track. A detecting and generating section (DG) detects a level difference between the two difference frequency signal components and generates a tracking control signal having a polarity and level which correspond to a tracking error. <IMAGE>

Patent GB-2140187-A (GB)
Title: Apparatus for testing and routing coins
Inventor: KNIGHT MICHAEL JOHN
IPC: G07D1/06
Filed: 1984-05-11
Abstract: A coin enters the testing section of a microprocessor controlled mechanism for testing and routing coins of different denominations and is first classified according to its characteristic dimensions by sensor 2. The microprocessor then optimises the parameters of a second sensor 114 according to this classification, which forms part of a Maxwell Bridge circuit for determining the material content of the coin and hence its denomination. The coin then enters the separator section where it either passes through gate 86 into an escrow for temporary storage if it is a high value coin, or through gate 87-89 into one of three change tubes if it is a low value coin, or out through exit 109 into the return chute if it is not a valid coin. The microprocessor keeps a tally of the number of coins in each change tube in order to optimise their payout through dispense gates 106-108 or replenishment through gates 87- 89. Downtime due to the mechanism being out of change is minimised by combining the change tubes with an escrow 111 which can hold a number of coins of different denominations and empty them either through exit 109 into the return chute or through exit 110 into the cash box. <IMAGE>

IPC: F23N5/00
Filed: 1984-10-23
Abstract: An atmospheric vibration sensor (15) comprises a flame (13) and an adjacent temperature-sensing junction (14) of a thermocouple. When the atmosphere is vitiated the flame lifts and the junction (14) cools thus allowing a microswitch (18) to open and shut off the electricity supply to a solenoid operated valve (2). Thus a gas supply controlled by valve (2) is shut off. The vitiation sensor may be mounted remote from the valve (2). A non-electric device is also described. <IMAGE>

Title: Decapping tool for removing used primer caps from spent cartridge cases
Inventor: KOHNE HANS-JURGEN
IPC: F42B33/04
Filed: 1984-10-24
Abstract: A decapping tool (1) for removing used primer caps from spent cartridge cases comprises a housing (2) containing a water reservoir. An internal piston (4) which projects from the upper end of the housing, when struck sharply, as by a hammer, compresses the water in a priming chamber, thereby opening a one- way valve and causing the water to follow a constricted path to and through a nozzle which has been inserted into the cartridge case so as to confront the cap at the base of the case. A high pressure pulsed jet of water is thus directed against the cap, which is forced from the case and into a cavity within an anvil upon which the cartridge case rests for the decapping operation. <IMAGE>

The logger (10) has mounted thereon a first coil (28) on a core (24) and the holder (12) has mounted thereon a second coil (28') on another core (24'). The logger (10) can be removably engaged with the holder (12) by detents (20) such that, when they are engaged, the windings (28, 28') are positioned with respect to one another so as to be coupled by electromagnetic induction to enable data from a source connected to wires 16 to be collected by the logger (10). The arrangement is described with reference to a water flow-meter in which a rotating magnet in co-operation with a reed switch produces pulses which are read-out when the logger (10) is engaged with holder (12). It is also stated that a pressure sensor in combination with an A/D converter can be similarly used to read out pressure measurements. <IMAGE>
