Title: Improvements in or relating to signalling apparatus for the control of road traffic
IPC: G08G1/082
Filed: 1929-12-13
Abstract: 345,209. Road signals for controlling traffic. STANDARD TELEPHONES & CABLES Ltd. and DAVIS, W. R., Columbia House, Aldwych, London. Dec. 13, 1929, Nos. 38230/29 and 2035/30. [Class 118 (ii).] A road-traflic control system comprises a device adapted to transmit electric impulses from a central station over a pair of conductors to a plurality of signal points connected in parallel thereto, each signal point being provided with relays for controlling signal means in synchronism with the transmitted impulses, and with means for adjusting the phase of successive signals along the route. Means are also provided for (a) manual control of the signals, (b) giving emergency signals along the route, (c) giving amber warning signals or special audible signals in the event of a line breakage, and (d) indicating by lamps to the controller the correct moment for return from manual to automatic control without making a sudden change of signal, such lamps also serving to indicate to a manual controller the phase of other signals along the route and thus to indicate the speed at which traffic is approaching the manually controlled point. The impulse transmitter located at a central contact point may comprise a brush driven over a bank of contacts by an electric motor. Relay E receives impulses from a pair of lines connected with the impulse transmitter, thereby causing the operation of a series of two-step relays A .. M in rotation to give a complete signal cycle. When M has operated, A is again operated to commence another cycle. Contacts from these relays are connected to a rotating ratio switch having wipers W\ W<2>, W<3>, which during rotation of the switch bridge contacts 1 .. 9. Relays G, GA, R, RA for operating the coloured signals are associated with the wipers W3, W<2> W<1>, the length of which determines the duration of the corresponding signals. Even progress of the traffic is maintained by the provision of means for adjusting the phase of successive signals along the route. Each common point of the two windings of each of the two-step relays A .. M is connected to a contact a . . j on a phase switch PS. The position of the wiper W<4> of the phase switch determines which of the relays shall be operated by the first impulse received. A mechanical phase control is also described with disc sequence switches. For transmitting special warning signals, the controller depresses a key to give a specially long impulse over the control lines, whereby relays with slow-release and slow-action characteristics are affected to give the desired results.

Title: Method and apparatus for effecting automatic control of the inlet pressure of a gaschromatograph column
IPC: G01N30/32
Filed: 1965-09-07
Abstract: 1,109,660. Gas chromatography. I. HALASZ. 7 Sept., 1965 [8 Sept., 1964], No. 38276/65. Heading B1L. [Also in Divisions F2 and G3]  Automatic control of the inlet pressure of a gas chromatography column is effected by means of a valve 3 having member 26 controlled by a membrane 22 which is supported by adjustable spring 19, gas being bled from line 1 through valve 13 and pressure reducing system 7 to counterpressure chamber 6 of  valve 3, thereby permitting an exponential pressure rise with time for the carrier gas passing through line 1 and gas chromatography column 5. In Fig. 2 (not shown), the gas is bled from a point in line 1 before valve 3 instead of after and in this case the pressure increase is proportional to the ratio of two hyperbolic tangent functions of time. In Fig. 3 (not shown) the principal column 5 is subjected to a temperature programme-thus affecting the flow resistance of the column. Additional gas is bled from line 1 through subsidiary column 27 under the same conditions as those obtaining in principal column 5. This gas bleed operates valve 28 so that on increase of temperature in the column and hence increase of flow resistance, the pressure in chamber 15 is lowered and valve 28 closed. As a result, less carrier gas from 7 escapes at valve 30, and hence valve 3 is opened so that the pressure of the carrier gas at the column inlet 5a is increased to compensate for the increased resistance of the column 5. The response times of the control circuits of the invention may be lengthened by the addition of side chambers of various volumes.

Movement of the pistons adjusts a swash-plate 2 through a lever 5, a spring 22 acting between the lever and valve 7. The spring 22 may be replaced by a leaf spring actuated by a toggle to provide a hyperbolic characteristic of the loading. In a further modification, the piston and valve are arranged in the one housing.

Abstract: 1,063,061. Cables. H.M. POSTMASTER  -  GENERAL. Oct. 7, 1963 [Oct. 11, 1962], No. 38629/62. Heading H1A. [Also in Division H2] In a coaxial submarine cable, of the type which has a high tensile strength core disposed within the inner conductor, "cockling " and possible cracking along a selected length of the outer conductor when the cable is flexed, particularly where the cable is jointed, is prevented by applying an external strengthening member over the outer insulating sheath, thus ensuring close contact between the outer insulating sheath and the outer conductor. The strengthening member may consist of twine, copper wire, galvanized wire, steel wire or plastics tape bound tightly round the cable along the selected length, the surface of the cable being prepared to receive the strengthening member by, for example, the application of a covering of petroleum bitumen-impregnated fabric tape. Fig. 1 shows a joint between the ends of coaxial submarine cables in which the outer conductors 3 are joined by tapes 8 of aluminium which are cold pressure welded as at 9 and 10 to the outer conductors and laid helically round the exposed insulant covering the inner conductors and high tensile strength cores which are initially secured together. Polyethylene sleeve 11 is then formed round the tapes 8 and moulded at 12 and 13 on to the original outer sheaths 5 of the cables, and around these junctions fabric tape 14 and strengthening wires 15 are applied. An outer covering of the fabric tape 14a is then placed over the wire binding 15. In a further embodiment (Fig. 2, not shown) two cables of different external diameters are joined. In this embodiment, one of the cables has a helically wound outer conductor instead of a longitudinal strip outer conductor, and thus reinforcement is not necessary since helically wound tapes can withstand the flexing that is liable to occur.
