Title: Power supply trip control for nuclear reactor
Inventor: HAGER ROBERT EDWARD
IPC: G21D3/04
Filed: 1986-10-17
Abstract: A control system for a trip coil (18) in a switchgear mechanism (10) controls the supply of electrical power to a process control device (14) and ensures de-energization of the trip coil shortly after the trip coil is energized. The trip coil is energized not by an independent dc source as in prior art, but from rectified power from a step down transformer (20) supplied from the switchgear output side. The transformer feeds a rectifier (22) which is connected to the trip coil (18) via a trip activation device (24, 26). The output of the rectifier can be monitored using an optical converter (32) to determine the ability of the control system to activate the trip coil and the condition of the power supplied to the process control device. The control device (14) may be a rod positioner in a pressurised water nuclear reactor. <IMAGE>

Title: Electrical plugs
Inventor: COX ANTHONY
IPC: H01R13/639
Filed: 1986-11-19
Abstract: An electrical plug comprises a plug body and a pin (2) projecting therefrom for insertion into an electrical socket. A bolt (17) is slidable in a transverse opening (18) in the pin (2) between a protruding position, and a retracted position. A shaft (13) extends longitudinally within the shaft to the bolt (17). The shaft (13) is held captive by a plate (32) fixed to the pin (2) and extending into a groove (31) in the shaft (13). Turning the shaft (13) in one direction extends the bolt (17) and in the other direction retracts the bolt (17). The extended bolt (17) prevents the pin (2) being inserted in the socket, or underlies the surface wall of the socket and prevents removal of the pin (2). <IMAGE>

Title: Propulsion slip control system of a motor vehicle
Inventor: RUHL THOMAS
IPC: B60K28/16
Filed: 1988-12-05
Abstract: The instantaneously effective coefficient of friction between vehicle and road is determined from a graph as a function of the measured values of the vehicle speed and of the vehicle longitudinal acceleration and a wheel slip value associated therewith is used as a threshold value for the propulsion slip control system. If the wheel slip exceeds the threshold value the engine throttle flap and/or the brakes of the driven wheels are operated to reduce vehicle propulsion. The coefficient of friction may additionally be accessed from the graph dependent upon steering angle, vehicle weight, throttle flap angle, accelerator pedal position, gear position and convertor characteristic.

Title: Reminder alarm device
Inventor: ITOH AKIO
IPC: G08B21/24
Filed: 1990-03-12
Abstract: The device includes an accessory switch detection circuit 11 for detecting ON/OFF states of an accessory switch eg an ignition switch 4 provided in a vehicle. An accessory switch detection signal VS is sent to an alarm generation circuit. The alarm generation circuit generates an alarm signal VBZ when the accessory switch is in an OFF state and a detachable electronic equipment, eg a vehicle stereo 7, is actually attached to the vehicle. This alarm informs a driver that he has forgotten to detach the electronic equipment, thus preventing possible theft. The alarm signal may be generated a preset period after detection that the accessory switch is in the OFF state if the electronic equipment has not been detached during the preset period. Alternatively, the alarm signal is only generated after the accessory switch has been turned to the OFF state and after the driver has vacated the vehicle, if the equipment is still attached. <IMAGE>

IPC: D01G23/08
Filed: 1991-02-19
Abstract: In an apparatus for the pneumatic feeding of at least one fibre-processing machine (e.g. a carding machine), by means of feed shafts (4a to 4d) connected upstream of the individual fibre-processing machines which feed shafts are connected to a common pneumatic transport line (3), the transport line is connected by way of a fibre-material-transport fan (1) to the upstream fibre-processing machine (2) (e.g. a fine opener). In order to achieve better fibre feeding in the feeding device and to allow a broadening of the working ranges, an air branch line (9) is connected to the transport line (3) and the amount of air in line 9 is controllable. A pivotable throttle flap 11 opens or closes the cross-section of line 9 to a greater or less extent to regulate amount of air in line 9. A sensor 5 is connected via a regulator 7 to a motor 8 which drives opener roller in opener 2 at a speed dependent upon signal from regulator 7. Air-mount measuring device may be provided in lines 9 and 3. There may be a common control for all the variables (figure 5). <IMAGE>

Title: Smoke detection device
Inventor: HUNTER COLIN EDWARD
IPC: G08B17/103
Filed: 1991-10-04
Abstract: A light metering device for detecting the amount of smoke in smoke-laden gas in which a source (15) emits a light beam into one end of a cylindrical chamber, which contains a sample of the gas. The light beam travels along the chamber and is modulated by a light interruptor (20) before being reflected, at an acute angle back through the chamber on to a detector (16) located adjacent to the source (15), by a reflector (17) located at the other end of the chamber. The detector includes a demodulator arranged so that only the light which has travelled the full length of the chamber will be detected. The device may include: reflectors arranged to cause the light beam to traverse the chamber a plurality of times before being directed on to the detector (16), clean air shielding to prevent contamination of the optics and subdividing of the chamber to reduce the amount of stray signals. <IMAGE>

Title: Air-fuel ratio control apparatus for IC engine
Inventor: IKUTA KENJI
IPC: F02D41/12
Filed: 1991-11-18
Abstract: An air-fuel ratio control apparatus for an internal combustion engine 10 which is equipped with an air-fuel ratio sensor 36 for sensing an actual air-fuel ratio of a mixture introduced into the engine and a target air-fuel ratio setting section for setting a target air-fuel ratio of the engine. Also included is a controlled-amount calculating section 20 for setting an optimal feedback gain on the basis of a predetermined dynamic model of the engine to calculate a controlled amount in accordance with the optimal feedback gain so that the actual air-fuel ratio becomes equal to the target air-fuel ratio. A fuel supply amount to the engine is determined on the basis of the calculated controlled amount, and the control responsibility of the controlled-amount calculating section is suppressed when the engine is in a speed-decreasing state. PI control may be used in the speed-decreasing state. This arrangement can adequately control the air-fuel ratio of the engine irrespective of the engine speed-decreasing state. <IMAGE>
