Title: Safe-slope alarm system
Inventor: SPENCER EDDERSTON ROAD HENRY B
IPC: G01L5/28
Filed: 1982-06-02
Abstract: A safe-slope meter 10 e.g. for use on a tractor, consists of a pendulum transducer 12 comprising a damped pendulum and coupled to a potentiometer 14. The analogue output of the potentiometer 14, following a brake test with the tractor, is sampled in a peak/trough detector 16. A microprocessor 18 comprising signal processing unit 20 and arithmetic unit 22 controls the sampling and sums, averages and displays the safe-slope limit in degrees on a digital display 24. If desired, a suitable programmed small computer may be used in place of microprocessor 18. With the meter 10 described above, the driver can predict the safe working limit of slope for any tractor/implement combination by doing a simple locked-wheel brake test. Tests may be done continually or based on a predetermined number and the results arranged. An alarm is provided when the actual slope angle equals or exceeds a critical value. <IMAGE>

Title: Rotary kiln coal gasifier with tar injection to suppress dust entrainment in gas
Inventor: PETIT PETER JOSEPH
IPC: C10J3/02
Filed: 1982-10-29
Abstract: A method and apparatus is disclosed for reducing entrainment of fines of feed stock material in tar- laden gases produced by a rotary kiln in the gasification of coal or other carbonaceous material. The fines and tar are both separated from the gas and from each other. The separated fines are recycled by admixing and churning such fines with newly provided solid carbonaceous feed material and recycled tar in a screw conveyor (8) prior to introduction of such mixture into the kiln (6). The mixing and churning action in the conveyor (8) causes the tar to coat particles of the newly provided feed material with tar and thereafter cause the fines to adhere to the tar-coated particles to form a composite agglomerate thereof. Such agglomerates when discharged into the kiln (6) by the conveyor (8), will travel a greater distance into the kiln (6) and away from the gas outlet (17) than the distance travelled by discrete fines. Fines adhering to the tar-coated particles as part of a composite agglomerate are, therefore, less likely to be carried out of the kiln by gas flow prior to gasification of such fines than are discrete fines. <IMAGE>

Title: Method of determining whether or not a throttle mechanism of an internal combustion engine is bearing against a throttle valve actuator
Inventor: MISCH WOLFGANG
IPC: F02D11/10
Filed: 1985-06-07
Abstract: A method of determining whether or not a main throttle mechanism of an internal combustion engine is bearing against an electro-pneumatic or electric motor-driven throttle valve actuator which acts as a stop on the mechanism in the throttle closing direction, comprises carrying out test operations at specific time intervals by loading the throttle valve actuator with control signal pulses S2, directed in the opening direction of the main throttle valve mechanism, which pulses lead to an adjustment of the position of a stop rod 5 of the actuator only when the throttle valve mechanism is not bearing against the actuator, whereas when the throttle valve mechanism 7 is bearing against the rod 5 of the actuator no position adjustment takes place. The reaction of the actuator to each such signal is sensed and is evaluated as an indication of whether or not there is bearing. Suitable threshold values of the signals and reaction may be provided, and if necessary these can be made adjustable as a function of operating parameters of the engine or external operating parameters. <IMAGE>

Title: Character joining - electronic - arabic script
Inventor: JONES JOHN ROBERT ALFRED
IPC: G06F3/01
Filed: 1985-06-25
Abstract: In some living language scripts the formal shape of a character may change according to its position in the word. In arabic script the four forms are isolated, final, initial and media). The procedure detailed in this invention may be programmed into hard logic as in the case of electronic typing machines and plotters or set out as a procedure in a word processor. Character strings in isolated form representation enter the logic. The function of the logic is to determine the correct form of character to be used in the written joined string, from the character weight codes of the characters in the string (the character weight code is the number of possible forms for the character, minus one), the form being specified as 0, 1, 2 or 3 for isolated, final, initial and medial respectively. Fig. 3 shows an example. <IMAGE>
Patent GB-2180917-A (GB)
Title: Electro-mechanical rotary valve
Inventor: MACDONALD BRUCE WARREN
IPC: B67D1/04
Filed: 1985-09-27
Abstract: An electromechanical rotary valve which can be installed in any public house enables the publican to connect three barrels of beer and a gas cylinder, to the dispensing point, thus ensuring a continuous supply until all three barrels are empty. The rotary valve initially connects the first barrel B1 with the gas cylinder G and the dispensing outlet. When the barrel B1 is empty, an associated float in a chamber FC closes an electric circuit to drive the valve. A micro-switch tripped by a cam on the valve shaft stops the valve in a position which connects the second barrel B2 to the outlet and the gas cylinder. This process is repeated when the second barrel is empty. The cycle may be automatically repeated. A simple push button bleeding mechanism is provided for easy and economical removal of froth and air from the system. An indicator light positioned either on the barrel or at the dispensing point shows which barrel is empty. As the valve only requires power during the switching operation from one barrel to another, very little current is consumed. <IMAGE>

Title: A wide bandwidth radar
Inventor: MOLYNEUX-BERRY ROBERT BEWES
IPC: G01S13/02
Filed: 1985-11-12
Abstract: A waveform generator drives a number of microwave generating devices (Tx) each operating at different frequency bands of one octave or less in bandwidth, spaced so that in combination the devices are capable of operating over a bandwidth of more than one octave. The output of each microwave generator is connected to its own transmission channel (e.g. 1-4) of limited bandwidth, which contains all of the non-linear components necessary for transmission, such as an amplifier, T/R switch, rotary joint and beam switch. These individual channels are finally combined on to a common wideband channel which contains only substantially linear components such as a single waveguide and the antenna itself. Because of the isolation between channels there is little or no opportunity for the generation of harmonics or intermodulation distortions which would otherwise occur in a transmitter capable of operating over a very wide bandwidth.
