Title: Improvements in or relating to doors and fastenings therefor
IPC: B60J5/00
Filed: 1932-01-20
Abstract: 393,355. Door fastenings. STIRLING, R. J., Pympe Manor, Benenden, Kent. Jan. 20, 1932, No. 1762. [Class 44.] To prevent a vehicle or other door from becoming jammed by accident or otherwise on lateral displacement of the door, the meeting edges of the door 12 and post 13 are inclined so that displacement of the door to the left, Fig. 1, initiates opening movement, the fastening being automatically released by the displacement. The fastening shown comprises a striking-plate 27 inclined to the direction of opening movement of the door, so as to lie in the path of a T-headed bolt 16 carried by the door edge. Plate 27 has an open-ended slot 28 allowing passage of the bolt head 17 when this is disposed parallel to the slot, but preventing such passage when the head is inclined to the slot. The bolt head, which is received in a recess 26, is rounded, and the edges of the slot are chamfered, to facilitate entry of the bolt-head on closing the door. Normally, the head 17 is held in inclined position by a spring 23, and is rotated to the horizontal position by handles 21, 22, the spindle 20 carrying an arm 19 engaging an arm 18 on the bolt 16, which is rotatably mounted. Normally a gap 14 exists between the door and post, covered by a sealing strip 30 on the door. When the door is displaced to close the gap, the bolt head moves to the left far enough to clear the outer end of the striking plate, so that the door is free to open. A modified fastening is described in which the T-headed bolt is replaced by a pivoted hook engaging over the lower edge of slot 28.

Title: A process for evaporating a solution containing a non-volatile solute unstable at elevated temperatures
IPC: C13B25/00
Filed: 1958-01-20
Abstract: <PICT:0835645/III/1> A process for evaporating a solution containing a non-volatile solute unstable at elevated temperatures comprises a plurality of like successive steps, each step comprising evaporating a solution containing a non-volatile solute at an elevated temperature while in passage through a tube or tubes wherein the residence time of said solution in said tube is insufficient to allow any appreciable decomposition of said non-volatile solute, and passing the effluent liquid-vapour mixture from said tube or tubes into a less confined space than said tube or tubes thereby obtaining separation of the effluent vapour and concentrated solution.  The process is particularly applicable to the production of sugars by the hydrolysis of wood by means of hydrochloric acid.  In a preferred embodiment a sugar solution containing 16.6% of mixed sugars from deciduous trees and 33.4% of HCl was fed at the rate of 12 kgs. per hour to an evaporator 1 operating under atmospheric pressure which may be fitted with graphite tubes 3 metres in length and with an internal diameter of 15 mm.  The tubes are heated externally by steam at 150 DEG  C.  The acid solution flows through at a velocity of 20-40 metres per second and then passes to a separator 2 from which the thickened sugar solution flows through a throttle valve 3 into another evaporator 4 which is heated by the acid vapours from evaporator 1.  The sugar solution leaves separator 5 at about 65 DEG C. and passes to a natural circulation evaporator 8 from which 3 kgs. per hour of sugar solution passes with a sugar content of 66%.  The evaporator tubes may preferably be fitted with bars (Fig. 2, not shown) which fit into the tube walls but make very little contact therewith.  In a further embodiment (Fig. 3, not shown) the solution may be passed downwards.

The capacitance ratio of the second capacitor C2; C4 to the first capcitor C1; C3 is preferably not less than 0À4. As shown when the clock signal #1 is applied T and T2 conducts and the data input signal at IN is transmitted to the gate of T3 and charges a capacitor C2. At the same time T3 conducts and the capacitors C3 and C7 of the memory circuit M2 are charged and point P falls to a negative value (Vpa, Fig. 3, not shown). The clock signal #1 now ends and when the clock signal cp2 is applied T4 and T5 conduct and T2 and T3 are off. A charge division is effected among the capacitors C3, C4 and C7 so that the capacitors C3 and C7 become partially discharged and C4 is charged. The potential at P becomes more negative (Vpb). At the same time as C4 is charged T6 conducts to provide an output. The charge dividing arrangement provides stable operation. The first and second capacitors C1, C2 may be formed with the junction capacitance only. The capacitors C6, C7 may be of silicon dioxide. The shift register may be formed as an integrated circuit.

Abstract: 1,090,725. Television navigation aid. ELECTRIC & MUSICAL INDUSTRIES Ltd. Jan. 18, 1965 [Jan. 18, 1964], No. 2286/64. Heading H4F. [Also in Divisions B7 and G3] In a television navigational aid, suitable for guided missiles or for aircraft 1, wherein a forward view of the terrain is not available to the pilot, a television camera 2 in the aircraft 1 views said terrain and transmits the picture, together with compass and altitude information, to a ground control station, where the picture is displayed at 9. Superimposed on the display 9, either mechanically or electronically, are a system of lines 11, radiating from a point representing the point at infinity in the display, towards which the aircraft is moving. A ground object will appear on the display near the radiant point and will move along one of the lines 11 until it passes the aircraft at a lateral elevation # relative thereto corresponding to said one line. If the height h of the aircraft relative to the object is known its lateral displacement from the aircraft's path is given by h cot #. Thus, each line may be given a value # or cot #. A movable radial line 12 may also be provided, movable under the control of means 14 which indicates # or cot #. A horizontal line 13 may also be provided representing points on the ground at a known distance ahead of the aircraft for a known aircraft altitude. The horizontal line may be fixed or movable. A computer 10 has the co-ordinates of various landmarks along the route stored in it, and also stores the position of the aircraft relative to each landmark when it is flying on the correct route. When a landmark on the display coincides with the intersection of lines 12 and 13, a button is pressed and the resulting co-ordinates of the landmark are passed to the computer for comparison with the stored co-ordinates. Any difference indicates that the aircraft is straying from its correct route and corresponding correction signals are transmitted to the aircraft to actuate an autopilot 7. If the landmark is wrongly identified, the position co-ordinate error determined by the computer will be very large, and the computer is thus programmed to ignore such large errors. The display may also be presented to the pilot for similar navigational purposes.

Title: Motor control system
IPC: H02P7/29
Filed: 1964-01-20
Abstract: 1,056,563. Automatic speed control. GLOBE INDUSTRIES, Inc. Jan. 20, 1964 [June 10, 1963], No. 2464/64. Heading G3R In a speed control system for an electric motor 10, a reference pulse generator in the form of a relaxation oscillator comprises a capacitor 21, and a silicon controlled rectifier 22 for periodically discharging the capacitor to produce a series of pulses over line 24. These pulses are applied to a storage capacitor 28 which is adapted to discharge through transistor 29 to produce voltage pulses across resistor 31 for triggering silicon controlled rectifier 35. When the rectifier 35 becomes conductive, a power transistor 38 is turned on to apply pulses to the motor. A motor-driven commutator 16 short-circuits capacitor 40 at intervals, to extinguish the rectifier 35, and render the transistor 38 non-conductive, whereby the power pulse applied to the motor is terminated. In this manner, the motor operates at a speed corresponding with the frequency of the reference pulses. An under-speed arrangement produces rapid acceleration of the motor when starting, the capacitor 28 retaining its charge for extended periods to maintain almost continuous energization of the motor until it reaches frequency synchronization with the relaxation oscillator. For overspeed regulation, the reference pulses are suppressed to delay the application of power pulses to the motor. When the commutator switch 16 closes twice in succession before the next reference pulse is produced, transistor 45 is rendered conductive through capacitor 50. Transistor 44 is also rendered conductive to short-circuit capacitor 21 momentarily. This delays the production of the next oscillator pulse. If the over-speed condition persists, this action is repeated to reduce the power applied to the motor until frequency synchronization with the pulse source is restored.
