Abstract: 375,952. Maps. SPENCER, A. E., The Bungalow, South View Road, Harpenden, Hertfordshire. May 22, 1931, No. 15133. Addition to 342,818. [Class 146 (ii).] A route indicator comprises a map or chart having spaced punched holes &c. translucent portions e along certain routes, and panels 4, 5, 6, slidable behind the routes and arranged so that in one position they render the holes &c. conspicuous and so indicate the route, while in the other position they render the holes &c. inconspicuous, the panels being moved on operation of a corresponding press-button and restored to original position by a spring. The panels are slidable in guideways d in the backing b of the map and are actuated by press-buttons j connected to the panels by push-rods, or by cords or chains k passing round pulleys l. The panel 6 is directly actuated from a pushbutton, and can also be actuated through the panels 4, 5, by cords m, n. A spring o acting on the panel 6 serves to restore the parts to non-indicating positions. The pressbuttons may be engaged by a catch-bar to retain them in set position, the catch-bar being moved by an operated button to permit a previously-actuated button and its associated parts to return to non-indicating positions. By operating two push-buttons at once, the route between distant places can be indicated. The routes are preferably formed with holes, and the panels are provided with distinctive markings which, in one position of the panels, register with the holes in the route. The panels are marked or coloured to match the routes when in non-indicating positions. Alternatively, the panels may be perforated to permit light to pass to the back of the map.

Patent GB-1360487-A (GB)
Title: Visual display device
IPC: G09G1/10
Filed: 1971-05-15
Abstract: 1360487 CRT displays INTERNATIONAL COMPUTERS Ltd 12 May 1972 [15 May 1971] 15152/71 Heading H4T In an arrangement for drawing lines on a CRT display a series of pairs of co-ordinate values are produced by 2<SP>n</SP>. Successive additions of values #x/2<SP>n</SP>, #y/2<SP>n</SP> to start values X, Y, these pairs cotrolling the beam deflection. X and Y are loaded from 30 via 28, 10 and 31 into registers 5 and 15, and the line increments #X #Y into registers 7, 17. The increments are simultaneously both shifted right until neither left-hand-side 7a, 17a contains significant digits (as detected by 8, 18) and these shifted increments are then repeatedly added to the contents of 5, 15 in the lower order positions, the upper order digits used to derive analogue deflection values thus receiving periodic overflows from 5b, 15b. The number of bit positions in 5a, 15a is chosen so that a change in their lowest order corresponds to the tube spot definition; however the range of deflection values which these registers command exceed the picture area, so that the actual display is part of a larger virtual picture. The co-ordinates of the centre of the displayed picture with respect to the larger virtual picture are supplied from 9 to subtractor 10 as the start values X, Y pass through 10 as referred to above. Each addition of the shifted increment values adds a 1 from 11 (shifted downwards correspondingly to the right shift of #X, #Y) into counter 13 until its contents again reach zero indicating that the end point of the line has been reached. Field indicators 19 and 29 and AND gate 20 detect whether the current X and Y values being supplied to the D-A converters 3 and 4 are both so small as to represent a point on the tube face; when this condition does not obtain skip logic 21 is brought into operation. This examines successively the bits registered in counter 13 and controls shift and addition of the contents of 7 and 17 to complete the incrementing with a minimum number of additions. To deal with lines which start off the tube face a series of "trial sums" are attempted starting with the full increment and then successively (if necessary) ¢, “ &c. of the increment, and while the result lies outside the tube face the sum is loaded into 5, 15; if inside the field indicators 19, 29 inhibit the over writing of the old values in 5, 15. Zoom register 31, by controlling a shift of the orders in registers 5, 7, 15, 17 into which the data is originally loaded controls the scale of the display.

Title: Improvements in or relating to hydraulic rams
IPC: F02D9/00
Filed: 1943-09-16
Abstract: 572,936. Fluid pressure servomotor control systems. COLLEY, R. H. Sept. 16, 1943, No. 15227. [Class 135] Fluid-pressure apparatus comprising a reciprocatable piston adapted to be set to and maintained in either of its end positions or an intermediate position by the continuing supply of fluid to it is described as applied to the control of a change-speed gear for the supercharger of an aircraft engine, the valves which determine the path of flow of the fluid being operated by solenoids automatically controlled by aneroid devices responsive to the altitude of the aircraft. As shown, a differential piston 13, 14, connected to a lever 11 operating the change-speed gear, is arranged in a cylinder 10 having ports 22, 23 at the ends, a central drain port 19 which is uncovered by the piston as it approaches either end of its stroke, and further ports 20, 21 both open or partly so when the piston is in its intermediate position. The flow of fluid from the supply line 28 is controlled by a pair of spring-pressed two-position valves 24, 25 operated by solenoids 40, 41 which are connected to a battery 46 and put into and out of operation by switches 42, 43 automatically actuated by expansible capsules 44, 45. Fig. 1 shows the piston 13 in its intermediate position in which it is maintained when both valves 24, 25 are raised, the flow of fluid from supply 28 to drain 33 being as shown by the arrows ; any movement of the piston away from the midposition will close one of the ports 20, 21 and thus cause a pressure build-up on one side which acts to return the piston to midposition. When both valves 24, 25 are lowered, the piston moves to the left-hand position shown in Fig. 2, while movement to the righthand position, Fig. 3, is effected by raising valve 24 only ; in both cases any movement away from the end positions closes the port 19 causing a pressure build-up with the piston to the appropriate end. The capsules 44, 45 and switches 42, 43 are so arranged that at ground level the switch 42 is closed and the switch 43 open, both solenoids being energized to maintain the valves 24, 25 in the raised position and thus keep the piston 13 in the mid-position shown in Fig. I to set the supercharger at its lowest speed ; as the aircraft rises the switch 42 opens and both solenoids are de-energized to move the parts into the position shown in Fig. 2 in which the supercharger is set to medium speed. Finally, on further increase in altitude, the switch 43 closes to energize the solenoid 40 and so raise the valve 24 to move the piston to its third position, Fig. 3, and so give the highest speed drive to the supercharger. Modified arrangements of the switches 42, 43 are described as is also a construction in which a manually -operable switch is provided to enable the pilot to over-ride the automatic control and set the supercharger to high, medium or low speed as desired..
