Title: Electrical monitoring system, particularly for traffic control
IPC: G08G1/082
Filed: 1959-12-24
Abstract: 943,961. Road signals for controlling traffic. LABORATORY FOR ELECTRONICS Inc. Dec. 24, 1959 [Jan. 6, 1959], No. 43934/59. Heading G4Q. In a system of the kind disclosed in Specification 843, 916 in which the local controllers are controlled over two 3-phase systems RF, VF of which one varies in phase slowly and progressively with respect to the other, the master controller includes a system supervisor which responds to the cessation of the phase variation and brings in emergency control arrangements. As shown, the two 3-phase systems are supplied from fixed coils RF<SP>1</SP> and coils VF<SP>1</SP> which are rotated at a variable speed under the control of the system selector or cycle selector. In the system supervisor three monitoring circuits B1...B3 are connected respectively between line a of system RF and lines d,e,f of system VF. The input to each circuit is thus an A.C. voltage amplitude-modulated at a low frequency which is extracted by a half-wave rectifier 25 to provide a varying D.C. voltage across capacitor 30. This voltage is differentiated by a capacitor 31 and resistor 32 and applied by way of a diode 34 across a resistor 36 common to the three circuits. The output voltages from B1...B3 reach their maximum amplitudes immediately after the respective input voltages pass through an in-place condition, and therefore occur 1/3 cycle apart, so that the resultant voltage across 36 is such as to maintain tube 39 continuously at cut-off. Thus, in the normal condition, relay F is de-energized, relays R, N, L are energized and motor M, which controls cam-contacts A, B, C, D according to the chart, Fig. 3, is stopped in the position shown. Suppose now that the motor driving coils VF<SP>1</SP> stops in the master controller. The phase shift between the systems RF, VF ceases, there is no voltage across 36 and relay F energizes. Motor M starts, lamp L1 lights and an audible alarm 89 is given. When motor M reaches period P2, N falls back and at contact SW1, Fig. 1, switches in an alternative power source 92, e.g. of fixed frequency A.C. to drive the master controller motor. If the output from circuits B1 . . . B3 is now restored, F de-energizes and stops motor M, but in any case lamp L2 lights and alarm 93 sounds. If the switching to the alternative power source is ineffective, indicating e.g. a fault in the motor or in the phase systenis, motor M continues to period P3, when L falls back, stops motor M and at contact SW2, Fig. 1, disconnects relays X at the local controllers which are normally energized over wire 1C. The local controllers now operate independently, and lamp L3 lights and alarm 94 sounds. Actuation of the reset button 56 releases R and restarts motor M to return to period P1, with N, L re-operating in period P4. If the output from only one monitoring circuit ceases, F energizes during a fraction of a cycle, and after two cycles motor M reaches period P2 and effects the emergency control. Modifications are mentioned, and in particular F may be a slow-operating relay.

Title: Line telegraph system with error correction
Inventor: DUUREN HENDRIK CORNELIS ANTHON
IPC: H04L1/18
Filed: 1962-12-07
Abstract: 1,014,180. Telegraphy. DE STAAT DER NEDERLANDEN TEN DEZE VERTEGENWOORDIGD DOOR DE DIRECTEUR-GENERAL DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. Dec. 7, 1962 [Dec. 15, 1961], No. 46253/62. Heading H4P. In an error-correcting simplex line telegraph system, when the receiving station detects an error it blocks its printer or perforator for one repetition cycle and sends to the transmitting station an RQ signal which has start polarity and which has a duration less than that of a clearing signal but longer than that of the longest signal of start polarity occurring in a code character. At the transmitter the RQ signal causes repetition to take place. The start polarity is obtained by applying a potential to the local repeater at the receiver so that the current flowing at the transmitter's repeater is of the same magnitude but opposite direction to that caused by stop polarity. The subscriber TORA is associated with a repeater LR A  comprising polarized relays A 1 , A 2  and transmits data to receiver TOR B  by way of repeater LR B . During normal transmission from contact zctA relay B 2  in TOR B  is energized in the stop direction and point P is positive relative to point Q, a1 being at + 60 v. When an error is detected contact RQ B  is reversed thereby driving B 2  to be energized in the start direction. Hence b2 applies a start potential to the line and A 1  reverses. Contact al is now at - 60 v. and so point P drops to zero volts relative to point Q. This lack of positive potential difference is taken to indicate that an RQ condition is present, and so a repetition cycle initiated. The repetition cycle starts with a service signal.

Abstract: 1,081,719. Electric correspondence control systems. SIEMENS A. G. Nov. 13, 1964 [Nov. 15, 1963], No.46426/64. Heading G1N. Also in Division F4] The quantity of blast gas fed to the hot blast stoves of a blast furnace installation is controlled to enable a desired amount of thermal energy to be carried to the furnace, during each cycle. As shown (Fig. 1), a first computer R2 establishes the maximum volume of blast gas (Qt)s required to supply the desired thermal energy per cycle based on predetermined values of the factors involved, e. g. calorific value of combustion gas, stove efficiency, etc. A second computer R1 determines the actual thermal energy Q 0  taken up by the blast gas in a stove and available for heating in the furnace, based on the temperature rise, volume, &c. of the blast gas passing through a stove. The figure (Qt) n-1  representing the volume of combustion gas used in the last cycle is stored at Sp 1  and combined at VR with (Qt) s  and Q 0  to determine the thermal energy Q n  to be supplied in the current cycle. The figure Q n  is measured by counter Z 1  and stored at Sp 2  for use in the next cycle. The value of Q n  may alternatively be based on the temperature TA of the hot blast gas when leaving the stove.

The element 17 is yieldingly returned during the damped stroke by spring 22. A central port closed by a disc valve 18 under pressure of spring 20 opens during the initial setting stroke to vent the chamber 5. A switch actuating rod 12 is coupled to an inner groove 10 of the element 17 by upstanding flanged lugs 9 and retains the valve spring 20 in position. The electromagnetic armature 44 is coupled to the switch actuator 12 through a single arm lever 49, coupled to a double arm lever 52 at pin and slot connection 51, 56, a spring 58 urging the lever 49 towards the armature 44. In the arrangement shown in Fig. 1 adapted to delay the contact operation on energization of the electromagnet the device is mounted with the actuator 12 engaging the end 59 of the two armed lever, so that on retraction of the armature 44 (as shown) end 59 moves clear of the plunger 12 to permit damped return by spring 22. The device may also be mounted so that the plunger 12 engages the end 60 of the two armed lever 52 whereby the damped movement of the actuator 12 takes place on de-energization of the electromagnet. With this arrangement a cap 47 retaining the return spring 58 is held down by the casing to increase the loading on spring 58 so that it overcomes the loading of the dash pot spring when the arm 49 is urged towards the retracted armature 44.

Abstract: 1361812 Walls and roofs F REINKE [trading as FRITZ REINKE ENG] 13 Oct 1971 47717/71 Heading E1W [Also in Divisions B5 and F2] A cover panel for a construction element comprises a first layer 1 of plastics material 0.4-0.6mm thick and a second layer 5, which may be adjacent thereto, comprising prestressed, parallel, plastics-impregnated fibres. The panel may further comprise layers 2 and 6 containing predominantly obliquely and/or transversely oriented plastics-impregnated fibres and a foil 4 of aluminium, steel or plastics to prevent vapour or steam diffusion: a removable protective plastics film may be present on the other side of layer 1. In Fig. 2 such a laminate (but omitting layer 4) is obtained by producing layer 1 from slot nozzle 12, heating it below element 13, spraying on chopped fibres and fluid plastics at 15, impregnating at 17 strands of fibres which are wound of spools (e.g. 200-3000 spools/m. width) 16 under prestressing tension, compressing by pressure or blows at 20, applying layer 6 of fibres from spray head 22 and compacting by vibratory pressure pads 22. The laminate is then heated on the endless band to cure and the band chilled to facilitate removal. A pair of such panels may form the outside skin of a construction element, the core of which may include interfitting filler members mounted transversely to the longitudinal axis of the fibres in the panel, the element being formed in a process wherein each of a pair of panelforming sheets, immediately after formation, has said filler members bonded thereto (Fig. 8, not shown) and said pair are then interlocked after the manner of the teeth of a sliding clasp fastener, a rapid hardening fibre plastics layer having been sprayed on to the mating sides (Figs. 9 and 12, not shown). If the filler members are hollow or contain inflatable sleeves, compressed gas can be introduced to press them against the opposite panel before setting of the latter layer. Fig. 16 shows filler members 49 of foamed plastics and of generally trapezoidal cross section having projecting edges remote from the bond to the panel at the shorter side and hoses 72 which on inflation pull the panels together. Fig. 21 shows a building element comprising a single panel on one side and a corrugated metal panel 73 and containing both filler inserts 74 and parallel iron members 77 welded to panel 73. Iron members of another cross section are illustrated in Figs. 19 and 20 (not shown) and in Fig. 26 two such elements are shown in which the metal panels are mechanically connected: alternatively a flat sheet may replace one of said elements (Fig. 24, not shown). Fig. 32 shows a construction in which a panel is formed into a cylinder 102: this is surrounded by a fibrereinforced plastics jacket 102a and a further jacket 103 the alternate lesser diameter portions of which are bonded to jacket 102 and the larger diameter portions of which contain foamed members 103a, 103b. Figs. 33 and 34 (not shown) illustrate building constructed of panels generally similar to that shown in Fig. 21.
