Abstract: 1296797 Heat pipes INTERNATIONAL BUSINESS MACHINES CORP 29 Sept 1971 31 Dec 1970] 45278/71 Heading F4U [Also [n Division H1] An electrical discharge cell which may be used in a vapour laser has one or more capillary wicks 103, 105, Fig. 1, containing a vapour source material and forming heat pipes. An electric discharge is struck between the wicks or separate electrodes, and material evaporates from the inner ends of the wicks and condenses at the outer ends. A temperature control maintains the end regions of the cell at or below the vapour condensation temperature, and the resulting circulation of vapour pumps neutral gas admitted to the cell through valve P to the ends of the cell where it forms a buffer to prevent window contamination. The wicks may be any capillary material able to withstand the temperatures involved, such as nickel, stainless steel or tantalum. If a non-conducting wick is used with a conductive vapour source material a conductor is extended into the wick. The power source of Fig. 1 may be replaced by an K.F. discharge coil around the cell. The cell temperature is controlled by heat exchanger 109 which may be a circulated liquid, an electrical heater, or a heating/cooling device such as a Peltier pile. The temperature control device 111 varies the neutral gas pressure. For laser use the discharge provides all the required heat, and the heat exchanger may be a finned body. In Fig. 2 annular wicks 233, 235 are used, each having guard rings at its ends, and the discharge is between separate electrodes 237, 239. The operation is as for Fig. 1, a region of neutral gas forming adjacent the Brewster windows 213, 215 to prevent contamination. Copper and thallium are possible laser materials.

Abstract: 1315525 Photo-electric control MINNESOTA MINING & MFG CO 14 May 1970 23446/70 Heading G1A [Also in Division G4] In a traffic control system, for a street intersection, a photo-electric detector receives pulsed light signals transmitted by an emergency vehicle approaching the intersection, which cause the traffic signal to indicate "Stop" in the cross street direction and "Go"in the direction of travel. For each street a photo-electric detector 36a, 36b Fig. 5 (not shown) is associated with each direction of travel, the detectors being connected in parallel and shunted by aninductance (37) to form a tuned circuit responsive to the pulsed light but not to steady ambient light. The traffic lights 11a are cycled by the control box 11b controlled from detector, 12b, which receives the signals emitted by the transmitter, 12a mounted on the vehicle 10. The transmitter consists of a lamp, 16, which provides pulsed, high intensity light, either visible or infra-red. The phase selector control unit, 35, then sends on a rapidly pulsed signal to step on the controller 11b so that a green traffic signal is produced along the street along which the vehicle crosses the intersection. Simultaneously, an emergency vehicle travelling towards the intersection along another street is prevented from affecting the signalling system. The actuator, 62, in 35, Fig.7 (not shown) applies a pulse series to relay 66 and a faster timing is substituted for the normal rate, the timing cycle is reduced, and the required green light is obtained earlier.

Abstract: 1347685 Transistor pulse circuits JOSEPH LUCAS (INDUSTRIES) Ltd 23 April 1971 [14 May 1970] 23394/70 Heading H3T [Also in Division F2] An anti-skid braking system for a vehicle which allows of a variable time delay between release and reapplication of the brakes has a winding 18 in which pulses are produced by means 19 rotating with the wheel to be controlled, so that the base of a transistor 17 receives an input signal representing the angular speed of the wheel, and a pump circuit constituted by a transistor 24 and its associated components produces across a capacitor 26 a voltage representing wheel speed. This signal is then applied to a differentiating circuit including an input capacitor 31 and a feedback resistor 57 and an amplifier comprising transistors 32, 39, 46 and their associated resistors and diodes acts with the feedback to produce at the collector of an NPN transistor 48 a signal representing the rate of change of the signal applied to the capacitor, i.e. the acceleration (positive or negative) of the wheel. With the brakes applied, when the deceleration of the wheel reaches a threshold value set by resistors 53, 54, a transistor 52 conducts and applies a signal through a resistor 56 to an amplifier to release the brakes. There will however be a delay between the initiation of conduction of transistor 52 and the actual release of the brakes and during this delay the continued deceleration of the wheel will produce an increasing signal at the collector of transistor 48, and this signal is integrated by an integrator constituted by transistor 52 and a capacitor 55. After the short delay the brakes are released and they cannot be reapplied until the transistor 52 turns off-if the integrator were perfect the transistor 52 would be held on by the capacitor 55 until the integral of the acceleration signal becomes equal to the integral of the deceleration signal during the short delay. However, since the integrator is not perfect the transistor 52 will turn off before this equality is attained.

Motor 4 may be pneumatic or hydraulic. When an hydraulic motor is used a valve block 7 is attached thereto and the motor and block are supported in the casing by a trunnion 5, and a recess 6, against the action of springs 8, 9. A spool valve spindle 11 is urged against a stop 12 by a spring 13 and is connected to triggers 16 by levers 18, 17. When pressure is applied to a bit held in a chuck 10 motor 4 and block 7 are pushed back relative to casing 1 but spindle 11 is prevented from moving by stop 12. The spindle therefore moves forward relative to valve block 7 and opens the valve so that fluid flows to motor 4 and rotates the drill. The drill can be rotated before being brought up to the work by depressing trigger 16.

Abstract: 1349529 Gating circuits; multiplex pulse signalling MICRO CONSULTANTS Ltd 27 Sept 1972 [20 Sept 1971] 43648/71 Headings H3T and H4L The bandwidth of a signal channel is momentarily widened so that the output can quickly follow sudden changes in input level and is then narrowed to reduce noise transmission, the channel output being sampled during the narrow band condition. The arrangement is suitable for periodically sampling an input signal but is described as applied to a multiplexer (Fig. 1). Each time a new channel is selected by electronic switches 11 the channel selection control 15 applies a signal via a filter control 17 to the noise eliminating filter 12 to momentarily widen its band and allow the output quickly to settle. When the bandwidth has narrowed again a delay trigger 16 enables a digital-to-analogue converter 14. In (Fig. 10) the filter R1, C1 has two sections each having an F.E.T. shunting the series resistor to control the bandwidth, the gates of the F.E.T.'s being controlled by the input signal via two unity gain phase reversers 1C1, 1C2 whereby the gate voltages follow the source voltages and maintain linearity. Restoration of the narrow bandwidth is controlled by a waveform generator 30-34 producing a preselected curve (Fig. 9, not shown). A "1" signal applied to inverter 30 cuts off transistor TR2 and is further inverted at 31 to produce an initial step at the input of 1C1, upon which is superimposed a slow exponential rise produced by charging a capacitor C20. When the combined voltage breaks down a Zener diode ZD2 the control signal rapidly rises to its final value.
