Title: Temperature control in an automatic washing machine
Inventor: GRAF RICHARD
IPC: D06F34/24
Filed: 1982-05-13
Abstract: A method of controlling the temperature of wash liquor in a programme-controlled drum washing machine, comprises causing the first feeds of cold and hot water to the machine for a washing operation to take place in a time-dependently controlled manner one after the other, the time control intervals being so adjusted in dependence on the time constants of the liquor-required regulating period that, even at extremely high temperatures of the hot water, the resultant temperature of the liquor does not depart substantially from a desired temperature ???s. The succeeding water feed intervals are then temperature- dependently controlled until a desired filling level EF is reached, the temperature measurement including a tolerance imposed by the time constants of the temperature measuring means and of the regulating period. As shown in Fig. 4, cold and hot water enters the machine through valves KW and HW, respectively, via a seal 12, the hot water passing through a washing agent chamber. A temperature sensor 6 is located in the vicinity of the sump. <IMAGE>

Patent GB-2135032-A (GB)
Title: Heat treatment of workpieces
Inventor: BOWES ROBERT GWYNN
IPC: F27D19/00
Filed: 1984-01-24
Abstract: A continuous heat treatment furnace has an entrance 6, a preheat zone 10, a thermal treatment zone 12, a cooling zone 14 and an exhibit 8. Curtains 16 and 18 are provided at the entrance 6 and exit 8 respectively. Nitrogen and hydrogen (or other reducing gas) are supplied to the furnace to create a non-oxidising or reducing atmosphere in the zones 12 to 14. Elongate workpieces such as tubes are advanced through the furnace and thereby heat treated (e.g. annealed). As the workpieces pass through the curtains so the tendency for air to leak into the furnace is increased. To counteract this tendency, position sensing plates 32 are adapted to actuate a signal generator 38 controlling a valve 42 which in turn controls flow of e.g. nitrogen to the furnace. The arrangement is such that the flow of nitrogen to the furnace is increased where ever a workpiece is sensed, thereby enabling the essentially reducing or non-oxidising character of the atmosphere to be sustained. If desired, the oxygen potential in the vicinity of the furnace entrance and exit can alternatively be monitored and used to modulate the flow of gas into the furnace. <IMAGE>

Title: Out of band signal measurement
Inventor: BARNES GEORGE JOHN PRESTON
IPC: H03H7/38
Filed: 1985-06-06
Abstract: To test key telephones for connection to the public network, out-of-band signals up to 10 MHz are measured. To measure these, the measuring apparatus is accurately balanced to earth so that common mode signals are not converted into transverse signals. A balancing circuit connected between the apparatus under test and a spectrum analyser, includes a balun (T1) whose primary centre-tap is connected to earth. As the centre tap may be inaccurate, the connections to the primary include capacitive and resistive components (R1-C3, R2-C4) which are adjustable for balancing. The DC line is fed via inductors (L1, L2) and there are decoupling capacitors (C5, C6). Balancing is enhanced by further adjustable capacitors (C1, C2, C7, C8) between the circuitry and the inside of the screening enclosure. Balancing is effected with the input terminals (B1, B2) operated together and an oscillator connected thereto, and repeated with the coupling leads (A1-B1, A2-B2) in place, in which case the short is removed to the outer ends of the leads. <IMAGE>

Filed: 1985-07-11
Abstract: A remote-controlled door lock designed for use in access-control systems has a spring bolt 1 adapted to be withdrawn by a handle-driven follower 13 (or a keylock cylinder). The bolt head 5 engages in a keeper 13 and can be retained in the locked condition by a pin 15 driven by a double-acting solenoid 14 to engage in a slot 17 in the bolt. In this condition the pin 15 also depresses one end of a pivoted bar 10 by which the follower 13 is linked to the bolt so that no forcing load can be applied to the solenoid locking mechanism through the handle. Opening of the door from this condition can only be achieved by release of the pin 15 by the solenoid 14 on recognition of a correct code presented to an associated card reader or similar device (not shown). <IMAGE>

Title: Alarm system with priority override
Inventor: PAYNE ROGER DENNIS
IPC: G08B26/00
Filed: 1985-08-05
Abstract: An alarm system suitable for fire detection, includes a plurality of transceiving units which each include a sensor for monitoring a parameter pertaining to, e.g. fire detection. A control unit transmits a sequence of polling signals to the transceiving units whereby the state of each transceiving unit is sequentially determined. Many transceiving unit detects a change in the monitored parameter which represents a priority condition, it communicates a priority signal to the control unit during the polling sequence. The priority signal is included in the response of the last-polled transceiving unit in such a way as to avoid interfering with the usual information contained in its response. A transceiving unit in a priority condition thereby interrupts the polling sequence and thereby reduces the response time of the system in detecting a priority condition. The priority signal is preferably a current pulse which occurs in a given position during a sequence of synchronizing pulses. The address of a priority transceiving unit may also be included without interfering with the usual response of the last-polled transceiving unit. <IMAGE>

Title: Döppler vibration measurement
Inventor: FRYER PETER ALEXANDER
IPC: G01S17/58
Filed: 1986-01-30
Abstract: To measure the velocity gradients over a vibrating surface using Döppler shifts in a beam of radiation 10b reflected from the surface but without the need for a beam frequency shifting mechanism, a part 10a of the beam 10 unaffected by the motion of the vibrating surface is combined with the surface-reflected beam 10b to form a composite beam on which a beat frequency at the surface vibration frequency is imposed, which impinges on square-law sensor 16 to produce a component at twice the vibration frequency but in which information about the sign of the beat signal is lost. In order to recover this information, and hence the direction of movement of the surface, the half cycles of a full-wave rectified signal of the composite beam which correspond to a negative Döppler shift are distinguished from those which correspond to a positive Döppler shift either by some naturally-occurring difference such as magnitude or by an artificial "tagging" of one set of such half cycles. <IMAGE>
