Title: Improvements in or relating to fire-resistant board material
IPC: C04B26/28
Filed: 1962-11-08
Abstract: A fire resistant board material consists mainly of water laid felted mineral fibres-but not asbestos fibres-bound together by an organic binder, and has a density of between 0.5 and 1.1 grams per cubic centimetre, with the fibres being in a condition of elastic compression.  The mineral materials may be stone, slag or glass.  As described mineral fibre wool, potato starch, zinc stearate and water are continously fed to a hydropulper with the pH of the suspension adjusted to by adding alum.  The suspension passes through a perforated plate in the hydropulper to a wet machine.  The wet matt thus formed is cut and then subjected to a pressure of about 6-8 kg/cm2.  Alternatively the suspension may comprise mineral fibres and potato flow, with an aqueous solution of urea resise being added to the surface of the wet matt.  A filler-for example kaolin-may be used.

Title: Improvements in or relating to Calculating Machines
Inventor: COCKSEDGE KENNETH WILLIAM
IPC: G06F7/50
Filed: 1966-09-26
Abstract: 1,153,532. Electronic key board controlled calculators. BELL PUNCH CO. Ltd. 21 Sept., 1967 [26 Sept., 1966], No. 42820/66 Heading G4A. In an electronic calculator having a source of trains of pulses and a plurality of orders of keys and in which each order of keys is associated with a respective pulse counter stage of a register and display means, operation of a key in each of a plurality of orders of keys serves to connect a train of puless to the respective counter stage in parallel and any carry pulse is carried into the next higher denominational stage during the generation of a second train of pulses. The key operated switches 14, pulse metering circuits 15-21, decode counter circuit 22, number tube 23 and carry circuit 25 corresponding to a single order of the calculator are shown (Fig. 1). On depressing a selected key (not shown), a corresponding one of the switches 14 is closed together with a common start switch 15. Closure of switch 15 applies a positive pulse to the base of transistor 17 which thus conducts and lowers the potential on line 20 connected to a bi-stable circuit consisting of cross-coupled transistors 18a and b. Closure of said one of the switches 14 connects a corresponding one of pulses P0-P3 (Fig. 2, not shown) from a pulse generator 13 to the line 20 to switch over the bi-stable circuit 18 and thereby enable a predetermined portion of a train of 10 pulses T from an oscillator 12 to pass by way of a line 21 to the counter 22. A pulse P9 applied to line 29 resets the bi-stable circuit 18 and transistor 17 at the end of the train of pulses. Operation of a further key within the same order would then cause a predetermined portion of a succeeding train of pulses to be added into the same counter 22. Carry signals from the counter 22 are passed by way of a line 24 to change the state of a bi-stable transistor circuit 25. This applies an increased potential through a switch 26 to a line 27 connected to the line 21 of the next higher order whereby a gate 28 in that order is opened to pass a pulse P0 in the next train of pulses to the corresponding counter 22. The same pulse P0 also operates to return the bi-stable circuit 25 to its previous state. Carry propagation may be suppressed by opening switch 26. The counters may be zeroized by operating a switch 30. Multiplication may be achieved by successive additions using the hand hold technique. Subtractions and divisions are performed similarly using complements.

Abstract: 1282777 Sonic vehicle-control JERVIS B WEBB CO 28 Aug 1969 [29 Aug 1968] 42863/69 Heading H4D A speed control for a vehicle 10 (e.g. a tractor) automatically guided by means of an energized wire or reflective band 14 and having a drive motor 92 comprises transducers 18 for emitting bursts of ultrasound in converging beams ahead of the vehicle, directional transducers 20 for receiving long range echoes and directional transducer 22 for receiving short range echoes. Timing circuits establish a short range gating signal and a long range gating signal following an emitted burst, which signals control a receiver amplifier and logic and alarm circuitry whereby any vehicle path obstruction giving an echo within the long range gate causes actuation of a long range alarm circuit and an obstruction giving an echo within the short range gate causes actuation of a short range alarm circuit. The long range alarm circuit drives a relay to switch motor supply batteries 93, 94 from series to parallel connection and hence to slow the vehicle. The short range alarm circuit disconnects the motor supply to stop the vehicle. Normal vehicle speed is resumed when the alarm circuits cease to be actuated.
