Title: Arrangements for receiving remote control signals
IPC: H02J13/00
Filed: 1963-01-29
Abstract: 1,009,052. Signalling over power circuits. ZELLWEGER Ltd. Jan. 29, 1963 [June 8, 1962], No. 3651/63. Heading H4R. Voice-frequency signals superimposed on a power circuit are derived therefrom by means of the tuned circuits 4, 5, 6, 7 and are applied via a rectifier limiter stage (Zener diode) 8 to a first capacitor 9. Provided the signals are of sufficient duration, i.e. are not high voltage interference pulses occurring at irregular intervals, the capacitor 9 rapidly charges-up to a value determined by the inverse voltage of the Zener diode and also slowly charges-up a second capacitor 11. The latter discharges rapidly through diode 10 in the event that the charge on capacitor 9 falls due for example to the reception of interference pulses. During reception of V.F. signal however, capacitor 11 eventually becomes fully charged and causes transistor 14 to conduct and thereby bring-up relay 19. The latter completes a self-holding circuit for a motor 20 which is thereby enabled to perform the cycle of operations required by the V.F. signal.

Patent GB-762384-A (GB)
Title: Improvements in or relating to electrical timing devices
IPC: G08G1/08
Filed: 1954-02-11
Abstract: 762,384. Road signals for controlling traffic. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., and RIDDLE, H. J. N. Jan. 27, 1955 [Feb. 11, 1954], No. 4073/54. Class 118 (2). An electrical timing device for use in association with a traffic-control system embodying pressure-actuated detectors including a pair of closely associated pressure detectors is arranged so that depression of one of said detectors causes a charge of electrical potential to be applied to an associated timing circuit for a period which is terminated by the depression of the other detector, the duration of time during which the changed state of electric potential is allowed to influence the timing circuit being utilized by the said timing circuit to assess the speed of the vehicle causing the depressions. This avoids the indication of an apparently slow vehicle when a fast vehicle with balloon tyres depresses a single detector for a disproportionately long time, the termination being signalled by the second detector before the tyre has moved off the first detector. In the embodiments shown detector tubes 1 and 2 are spaced apart about 3 in. to 5 in. and connected respectively to fluid pressure compartments 3 and 4 which have flexible walls 5 and 6. These carry movable contacts 7 and 8 cooperating with fixed contacts 9 and 10. Passage of a vehicle over detector tube 1 causes opening of contacts 7, 9 and passage over the second detector tube 2 opens contacts 8, 10. A valve device 12 delays the reclosure of contacts 8, 10 to ensure that contacts 7, 9 are reclosed first. In the embodiment of Fig. 1 the timing circuit input terminal 15 is normally at earth potential but on the opening of contacts 7, 9 becomes positive until opening of contacts 8, 10 breaks the circuit to supply 13. In Fig. 2 the terminal 15 is normally at positive potential and on opening of contacts 7, 9 becomes earthed. When contacts 8, 10 open it immediately receives a positive potential via rectifier 17 until contacts 7, 9 close to maintain the original condition. The valve delay device 12 also ensures that the system is inoperative to vehicles passing in the reverse direction. Specifications 647,268, 650,238 and 716,709 are referred to.

Abstract: 753,029. Concrete, fibre cement &c. tubes. MANNESMANN AKT.-GES. Feb. 12, 1954 [Feb. 12, 1953 ; Dec. 23, 1953], No. 4247/54. Class 99(2). In the manufacture of tubes from hardening substances for example concrete fibre-cement mixtures and the like the batch of wet material required for the manufacture of a tube is supplied to a core roller in the form of a flat continuous length corresponding to the length of the tube by means of a conveyer belt guided by tensioning and guide rollers and is applied to the core roller with one or more rotations of the latter and after application to the core roller has been completed the material on the roller is compacted in the course of a few more rotations by gradual adjustment of a pressure roller towards the core roller and is thereby brought to the wall thickness of the finished tube and while the material is being applied to the roller and compacted the tube is maintained below atmospheric pressure by using an evacuated core roller. The apparatus employed comprises a porous conveyer belt a core roller permeable to air and liquid a pressure roller arranged below the core roller and a tensioning roller arranged above the core roller and adapted to be swung out of its tensioning position in a direction normal to its axis advantageously into a plane which is disposed below the plane of the conveyer belt in the region where it enters the gap between the pressure roller and the core roller. A porous conveyer belt 1 comprises a driving roller 2 and main tensioning roller 3. Above theÀcore roller 5 is tensioning roller 7. The force of a pressure roller 6 is adjustable. This roller is operated by a pressure cylinder 8. While the pipe material is being compacted the interior of the core roller 5, which roller is permeable to air and water, is kept below atmospheric pressure. The tensioning roller 7 is moved to permit removal of the tube. An auxiliary tension roller 11 maintains the tension of the belt. To prevent belt slip the drive roller 2 may be uncoupled from its drive means. The roller 2 may be driven by a motor through an infinitely variable gear 14 and clutch 16. The clutch may be an overrunning clutch or an engageable or disengageable clutch, for example a magnetic clutch. The shifting movement of the clutch may be derived automatically from rocking movements of the tensioning rollers. Limiting rings 18, 19 may be provided at the ends of the roller 5, Fig. 3. The core roller may be perforated and covered with a thin water pervious fabric or may consist of porous ceramic masses or of fretted glass or of other sintered masses. The tubes may consist of two or more layers. The individual layers may consist of different mixtures or mixtures of substances having different proportions or properties.
