Title: A signalling arrangement in which switching is automatically effected by street vehicles
IPC: G08G1/08
Filed: 1928-12-05
Abstract: 301,809. Sternberg, A. Dec. 5, 1927, [Convention date]. Road signals.-In an automatic electric signalling system for controlling traffic at crossroads, contact members 20 - - 23 are arranged transversely to the direction of travel and when depressed by the approaching vehicles set in operation inter-dependent slow-return switch arms for the control of visible or audible signals at the point 17. The road contact devices are in effect responsive only to traffic moving towards the oiossing. Fig. 1 shows a contact plate 2 sunk in the road and pivoted on an edge 5, so that a vehicle wheel 1 travelling in the direction of the arrow first moves the plate in contact with a delay-action switch 3, which switches off again after a second or two; the wheel then moves the plate to close a contact 4 actuating the time switch for switching on and oft the signals. The time-control devices shown diagrammatically at 18, 19, Fig. 4, for the green and red lamp system 61 - - 68 include solenoid 36, 49 connected as shown with the read switches 20 - - 23 and adapted to move switch arms 39, 51 from contacts 47, 40 and 60, 53 to contacts 48 and 58 respectively, these arms returning slowly under the action of retarding-devices 42, 50 and taking in the contacts 41, 59 on the return journey. Upon repeated actuation of a road-contact while, say, the switch arm is still traversing the contact 48, the arm will again be actuated by the solenoid 36 and the period of " road clear " will be extended. When, however, the slowly-returning switch arm 39 is traversing the contact 41, the signals change and a pawl 44 engages a rack 45, thereby preventing the forward movement of the arm and yielding the " road clear" signal to the other road. When the returning switch arm leaves the contact 41 for the contact 47, all the signal lamps are extinguished in readiness for the next depression of a road-contact, a solenoid 43 being thereupon energized to remove the pawl 44 and free the switch arm.

A tank for storing liquefied gas at substantially atmospheric pressure comprises a roof 1 which is internally lined with a layer of porous material 14 e.g. sprayed foam plastic, or fibre glass attached to the roof by wire netting, and all the walls 11 and bottom of which are externally lined with layers 9, 10 of wooden planks as heat-insulating material. The layer of porous material may extend for a certain distance down the inside of the walls of the tank. When installed in a marine tanker the tank walls and bottom are of metal and the roof is formed by the deck of the tanker.

Abstract: 1317924 Capacitor transducers MARCONI CO Ltd 28 July 1970 [4 Aug 1969] 36381/70 Heading H4J A capacitor transducer has at least one capacitor plate (e.g. the back plate) in the form of a spiral winding of metal strip susceptible to anodic oxidation. Asperities (i.e. upstanding areas) are provided on one edge and a layer of oxide is formed on the edge by anodic oxidation. The oxide layer may be an electret. Preferred metals are aluminium and tantalum. A rod or tube of the same metal may be used as a winding form. The aperities may be formed in a regular pattern by rolling or punching. The main body of the plate may be commercial grade metal whilst that part which is to be anodically oxidized is of high purity metal provided by evaporation after winding. Alternatively commercial grade metal strip may have an edging of very pure metal rolled or coldwelded on to the edge prior to or coincident with the formation of the asperities. The wound plate may be retained by a band or by cementing of the outer layer. Further asperities may be provided on one surface of the strip to hold apart successive layers of the wound strip. In this way acoustic holes are provided through the plates. Blind holes may be provided by closing off the rear ends with lacquer or wax, or by cementing a thin synthetic film to the rear of the plate. The wound plate may be held in position thereby. In a noise cancelling arrangement a diaphragm moves differentially between fixed front and back plates both as described above.

Title: Cursor control system

Filed: 1970-07-30
Abstract: 1313146 Detecting displacement; counters INTERNATIONAL STANDARD ELECTRIC CORP 30 July 1970 [30 July 1969] 36914/70 Headings G4A and G4H The direction and amount of movement in two directions of a member is determined by incrementing or decrementing under the control of logic circuitry pulses from three sensors sensing two coded scales moving with the member, the counts being converted to analog signals to control the deflection plates of a cathode ray tube.  In the embodiment of Fig. 1 (not shown) and Fig. 3 for determining the rotation of a ball type cursor (11), the rotation of the ball in x and y directions is transferred to digital wheels (23), (24) each having marks sensed by photodiodes 31, 32, 33 (the X sensors being shown in Fig. 3) equally spaced apart from each other by a distance less than the spacing between marks on the wheel. The photodiodes control two bistables 35, 36 such that photodiode 31 resets the bi-stables, one of which is then set by the photodiode 32 or 33 first sensing a mark, this inhibiting the setting of the other bi-stable so that depending on the direction of movement a signal is delivered to counter 67 on lead 63 or 64. Count pulses are applied via OR gate 56 connected to the set outputs 43, 44 of the bi-stables and a coarse/fine switch 68 to the counter 67. The binary counter 67 (Fig. 6) comprises a chain of JK flip-flops 100.1 ... 100.n, to the clock inputs of which the counting pulses are applied and to the JK inputs of which count up/  down signals are applied via AND gates. The counter may operate in a coarse or a fine mode, bi-stable 125 inhibiting via gates 133, 134 higher order stages when switch 68 is in its " fine " position and applying potential to clearing inputs of the lowest three stages when the switch is in its " coarse " position. When full or empty further count up or cound town pulses respectively are inhibited (Fig. 7, not shown).  In a modification (Fig. 8, not shown) to prevent errors due to the digital wheels oscillating the diodes are spaced by more than the distance between adjacent marks on the wheel and the logic circuitry is modified so that a count pulse is only generated in response to a reset pulse from the first photodiode followed by a pulse from each of the other two diodes. In a further modification (Fig. 9, not shown) each digital wheel has only one mark. The optical sensing described may be replaced by inductive sensing or magnetic sensing using reed switches or a cam operating microswitch. The apparatus may be used for sensing the position of two drums one in the x and one in the y direction (Fig. 5, not shown). Alternatively the input may be from a linearly movable element.
