Title: Vehicle guidance
IPC: B61L3/00
Filed: 1972-12-29
Abstract: 1455118 Automatic control of steering ELECTRICAL RESEARCH ASSOCIATION 19 Dec 1973 [29 Dec 1972] 59996/72 Heading G3R A vehicle is automatically guided by a system in which error signals derived from a sensing head and guidance conductor are combined with D.C. reference voltages and a sawtooth waveform to control one or the other independent brakes on opposite sides of the vehicle. The sawtooth is generated at 3 from pulses produced by a wheel unit 1 and shaped at 2, the arrangement being such that the mean level of the sawtooth is related to wheel speed. However, for guidance purposes this speed information is blocked by capacitors 16, 17 in applying the sawtooth to operational amplifiers 14, 15. The guidance error is produced at 11 from sensors 11 a and the D.C. reference voltages from potential divider Rl, P1, R2. The output from 14 or 15 (according to direction of error) comprises pulses, the spaces between which correspond to the magnitude of the error and control the appropriate brake 9a or 9b via amplifiers 8a, 8b. The mean value of the sawtooth is compared at 6 with a reference 7; in the event of overspeed output pulses from 6 are supplied to both brake actuators via OR gates 10a, 10b to slow the vehicle, and also to a time delay CR network 8 which, if the overspeed pulses continue shuts off the engine at 9.

Title: Dual brake valves
IPC: B60T13/14
Filed: 1971-12-31
Abstract: 1374634 Dual brake valves CLAYTON DEWANDRE CO Ltd 12 Dec 1972 [31 Dec 1971] 60972/71 Heading F2F In an hydraulic dual brake valve, two valve assemblies, each assembly having a valve member 11 displaced with respect to a fixed seating 10, to control fluid flow between a pressure source connected chamber 3 and a brake line chamber 5, are actuated by a plunger 8 actuated by a balance beam 24, each member 11 being urged to its seating by a spring loaded tubular valve guide 12; a blow-off type safety valve 19 is disposed coaxially with each assembly in a further chamber 18 connected to the chamber 3 and when open discharges fluid through an exhaust passage formed axially of the valve assembly. Upon actuation by a thrust member 23 through the beam 24, each plunger 8 has a stem which engages one element 11b of the valve member 11, in the form of a dumbbell, to block communication between the brake line chamber 5 and passages 15, 16 to a reservoir. Further plunger movement lifts the other element 11a of the member 11 from its seating 10 to communicate pressure fluid to the brake line chamber 5 via a port 4, a filter 22, and the chamber 3. If the pressure exceeds a predetermined value, the safety valve is opened by pressure in the chamber 18, connected to the chamber 3 via a passage 21, to communicate the chambers with the reservoir. Braking reaction is produced by pressure fluid in the chamber 5 acting on a piston part 9 of the plunger 8. Upon pressure failure in one of the circuits, the associated plunger 8 moves leftwardly to engage a circlip 25 against a housing shoulder, allowing continued actuation of the other plunger.

Title: Determination of the Partial Pressure of Water Vapour in a Mixture of Gases
IPC: G01N27/416
Filed: 1978-11-29
Abstract: A method of, and apparatus for, determination of the partial pressure of water vapour in a mixture of gases. The mixture is allowed to impinge on one side of one or more membrane permeable to water vapour (6, 7). Any water vapour in the mixture diffuses through the membrane and is absorbed in a strongly hygroscopic electrolyte (4). A DC voltage is then passed through the electrolyte by. means of two electrodes (5) on opposite polarity. The water is decomposed yielding hydrogen and oxygen gases which are removed from the electrolyte in such manner as to prevent ingress of atmospheric moisture, and the current produced during the electrolytic decomposition is measured, the magnitude of the current being proportional to the partial pressure of water vapour in the mixture of gases. <IMAGE>

Patent GB-2013429-A (GB)
Title: Control of asynchronous motors
IPC: H02P/
Filed: 1979-01-04
Abstract: An asynchronous motor 4 is supplied by a static frequency changer 1, 2, 3 whose inverter 3 is controlled, over an upper frequency range, by pulses derived from the motor voltage and, over a lower frequency range when a sufficiently high voltage is not available, by external pulses. The latter are derived from the desired value voltage of potentiometer 5 feeding voltage/frequency converter 18 controlling inverter 3 through one position of a changeover switch 22. Firing unit 12 controls the inverter through the other switch position in accordance with pulses derived by members 13-16. Controller 19 receives the pulse trains from members 12, 18 and controls unit 12 to reduce to a minimum the phase difference between the pulse trains. Stage 21 responds to this condition and to trigger stages 20, 23 operable when the motor voltage and frequency exceed preset values, to change over switch 22 and ensure smooth transition from external to motor pulsed operation. Signals from members 8, 17 are compared with the potentiometer voltage to produce control signals for controllers 6, 7, whose outputs are summed to determine the phase of pulses from firing unit 10 for rectifier 1 and from unit 12. Further control is provided by signals from current sensor 11 and optionally from torque controller 25 if the motor is operated at a constant voltage/frequency ratio. <IMAGE>

Patent GB-2013900-A (GB)
Title: Liquid densitometer
IPC: G01N9/18
Filed: 1979-01-26
Abstract: In the device for, and method of, producing an electrical signal dependent on the density of an electrically conductive fluid, at least one float (5) is immersed in the fluid, the or each float (5) having a different electrical conductivity to the fluid. Electrical detection means are then used to monitor the resistances of first and second zones (3, 3') within the fluid, which zones (3, 3') are so arranged that, within the measuring range of the device, the higher the density of the fluid the greater the proportion of (one of) the float(s) (5) within the first zone (3) and the less the proportion of (one of) the float(s) (5) within the second zone (3'). These means may be constituted by three electrodes (E1, E2, E3) connected in a bridge circuit (4), the resistances (R1, R3) of the first and second zones (3, 3') forming two adjacent arms of the bridge circuit and further resistances (R2, R4) forming the other two arms. The voltage UM formed at the diagonal of the bridge circuit is dependent on the ratio of these resistances and therefore on the density of the fluid. The method has application generally for measuring the density of electrolytes. <IMAGE>

Title: Manufacture of Film From Partially crosslinked Polyethylene
IPC: B29C48/10
Filed: 1979-04-03
Abstract: A blown film process is disclosed, in which polyethylene film with a reduced transverse direction tear strength is produced. The process has a blow-up ratio in the range of 1.2:1 to 4:1 and a MD draw down ratio in the range of 2 to 60. The polyethylene is partially crosslinked and extruded into a film between 10 ???m and 100 ???m thick. The polyethylene before crosslinking has a density of between 0.940 g/cm<3> and 0.970 g/cm<3>, and a melt index of between 0.2 g/10 min and 15.0 g/10 min. The crosslinking should be sufficient to cause the film to have a substantial reduction in the Elmendorf tear strength in the transverse direction as against a film made under the same conditions using the same polyethylene not crosslinked. Any known crosslinking method may be used, examples of methods and sufficient doses are disclosed, as are preferred ranges for other variables.

Title: Improvements in or relating to the measurement of the strength of plastic materials
IPC: G01N33/44
Filed: 1979-04-27
Abstract: A device for measuring the strength of plastic material by reference to the axial force required to force the material through a convergent orifice. Precautions are taken so that friction or other forces exerted by the material upon the device during the operation do not contribute to the measured axial force. Material such as a soil sample held within a tube (16), is extruded by a piston (10) through a tapering die (20). The force thus exerted upon the die compresses bellows (23) and may be ascertained from the reading of a Bourdon gauge (25). <IMAGE>

Title: Fuel Injection Device for an Internal Combustion Engine
IPC: F02M51/06
Filed: 1980-05-09
Abstract: An injection valve 1 is fed with fuel at a high pressure and is opened and closed with the aid of a servo control circuit. A safety valve 47, provided in order to avoid uncontrolled injection if the needle valve 15 sticks, has a valve member 48 blocking the fuel supply duct 31 to the injection nozzle 5, in the direction of fuel flow when the needle valve 15 is supposed to be in the closed position. The valve member 48 is opened by an actuating piston 49 subject to hydraulic fluid supplied via a pressure duct 63. An electromagnet valve 37 is used for the actuation of a control piston 18 for the purpose of actuating the needle valve 15. The actuating piston 49 and the control piston 18 are both actuated by the opening of the electromagnetic valve 37; but because of the different lengths and cross-sectional areas of their pressure ducts 42 and 63, the piston 49 responds before the piston 18. <IMAGE>
Patent GB-2080382-A (GB)
Title: Improvements relating to latch mechanisms
IPC: E05B55/00
Filed: 1980-06-24
Abstract: A handle (6) is linked by co-operating flanges to a plate (14) by a bolt nose (2). The plate (14) can be moved independently by a lock mechanism (13) acting to rotate the plate (20) which will engage a pin (21) on the plate (14) to withdraw the bolt nose (2) into the body (1). The locking mechanism (13) incorporates a slot which, upon rotation, can be located in one or other of a pair of notches (28) in a hold plate associated with the plate (14) so as to lock the bolt in either the withdrawn or extended positions. A deadlatch nose (5), when withdrawn into the body (1), moves an associated plate (40) so as to allow a pin 48 to enter a notch so that a moulding (46) can rotate and allow a pin (47) to enter a notch (53) in the plate (14) (when the bolt nose (2) is extended) and thus hold the plate (14) against movement allowing the bolt nose to be withdrawn.

Patent GB-2067374-A (GB)
Title: Stable integrated transconductance amplifier
IPC: H03F3/45
Filed: 1981-01-08
Abstract: The amplifier comprises a current source Q1 to Q4 and an amplifying section Q5 to Q7. All transistors, plus the 3 resistors, are made in a single integrated circuit, so that sizes and other properties are matched. Q1 and Q2 form a current mirror, and Q3 and Q4 form a second current mirror; the current in Q2 is mirrored into Q1, and that in Q3 is mirrored into Q4. The output current of this current source is thus determined by R1. This sets the base voltage of Q7, which is the "tail" impedance for the transistor pair Q5 and Q6. The gain of the amplifier section is determined by the load resistors RL and the conditions at Q7. It can be shown that all variables (temperature, processing constants, etc.) cancel out, leaving the gain dependent only on the geometrical size ratios of the transistors and the ratio of the resistors, which are fixed. CMOS transistors can be used instead of junction resistors. <IMAGE>
