Abstract: 828,218. Protective cut-out systems. COMPAGNIE GENERALE D'ELECTRICITE. June 13, 1956 [June 13, 1955], No. 18330/56 Class 38 (5). In a polyphase system in which the insulated sheath of the cable is earthed through an auxiliary supply source 6 and tripping relay coil 7, which is energized when a foreign body earths the sheath, the sheath is connected to an arrangement of one or more capacitors and transformers to compensate for capacitive unbalance currents which may produce unwanted tripping when one phase is earthed external to the cable. In Fig. 2, the sheath 5 is connected to capacitors 12, 14 fed by the secondaries of transformers 11, 13 which are earthed at the other terminal. The primaries of these transformers are connected between phases 2 and 3, respectively, and the earthed phase 1. In Fig. 3 a single transformer 15 has its primary connected between the insulated, or an artificial, neutral and earth, this arrangement operating regardless of which phase is externally earthed.

Filed: 1971-06-01
Abstract: 1386604 Colour television BRITISH BROADCASTING CORP 12 June 1972 [1 June 1971] 18371/71 Heading H4F The black and white levels of the red, green, blue colour video signals from a television camera or telecine apparatus are adjusted to remove errors in the signals. The black levels are set using clamp circuits 28 controlled by corrector 20 receiving the output signals via feedback loop 18. Corrector 20 may operate in each field to set the black level of the green signal equal to areference level, the black levels of the red and blue signals then being made equal to the black level of the green signal. A variable gain amplifier 26 in the green channel is adjusted in each field by a circuit 22 to make the maximum value of the largest of the three colour signals equal to a predetermined value, variable gain amplifiers 26 for the red and blue signals being controlled by an "integrate to grey" circuit 24 so as to make the time integrals of the red, green and blue signals equal. Circuit 22 may control all three variable gain amplifiers 26, in which case "integrate to grey" circuit 24 may be omitted.

Title: Control means for electromagnetically actuated twin horns on road vehicles
Inventor: WHEATLEY DENIS
IPC: G08B3/10
Filed: 1960-05-31
Abstract: 913,536. Electromagnetically-operated twin horns. LUCAS (INDUSTRIES) Ltd., JOSEPH. May 16, 1961 [May 31, 1960], No. 19182/60. Addition to 872,212. Class 118. The control arrangement of the parent Specification wherein an electromagnet controls a two-way switch which passes current alternately to two horns, and is in turn controlled by an intermittently-operated further switch, is modified by controlling the further switch electromagnetically or by means of a cam on a rotary member of the road vehicle. Operation of push-button 3 energizes relay 4 (contacts 6a, 6b) and horn 13 thus operates. Prolonged operation of button 3 allows capacitor 10 to charge up so that eventually a relay comprising coils 8, 9 and capacitor 10 is energized. At its contacts 7a, 7c, this relay closes a circuit for relay 11 which in operating completes at contacts 12a, 12c a circuit for horn 14. Alternate operation of horns 13, 14 is obtained since relay 8, 9, 10 releases shortly after its actuation due to the discharge of capacitor 10. Alternatively, relay 8, 9, 10 may be replaced by a cam-actuated switch, the cam being driven by a rotating member of the road vehicle.

Title: Ice detection equipment
IPC: G01N25/56
Filed: 1972-04-26
Abstract: 1431751 Detecting icing of aircraft wings LUCAS INDUSTRIES Ltd 5 April 1973 [26 April 1972] 19272/72 Heading G1A Apparatus for detecting ice forming on wings, helicopter blades &c. comprises first means for effecting a count of a plurality of electrical pulses produced in operation by an ice detector, and second means for modifying the count depending upon the rate of production of the pulses. A suitable radio-active radiation source and a Geiger-Muller tube are placed adjacent the surface in question, the output of the tube being taken to a frequency discriminator whereby when the frequency of the output pulses falls below a certain level, indicative of a particular depth of ice, a pulse is produced of about 8-12 seconds duration which activates a de-icing operation. This pulse is also passed as input to the apparatus shown to effect an indication of the severity of icing and of the total amount of ice forming on the surface. When the surface encounters an icing situation, the first pulse from the frequency discriminator is filtered at 10 and shaped at 11 where it resets a flip-flop 16 to enable a gate 19 via an inhibit 24, operates a monostable 15 which activates a clock source of period approximately 25 seconds and causes clearing of a store 30 via a circuit 13 and the enabling of a transfer circuit via means 14 so that the count accumulated at 20 may be passed to the store. The delay output of the monostable 15 activates means 12 to reset, via circuit 21, the counter 20, which is a single decade binary counter to "001," and applies a pulse to counter 22. Counter 20 proceeds to count the clockpulses and if seven of these occur prior to the next at filter 10, the flip-flop 16 is set to turn off the apparatus. If a further input pulse occurs inside this time interval, the read-out to the cleared store 30 of the present count at 20 is effected and the counter 13 reset to "001" again and the operation continues, a further pulse being applied to the counter 22. The count repetitively stored at 30 is passed via a de-coder 26 to activate an indicator 31 to show whether the icing is "severe" or "medium" &c., and the pulses accumulated at 22 are de-coded at 33a to provide an indication at 34 of the ice accretion. If the count at 20 is e.g. less than "011" when the next pulse is received at 10, a gate 33 opened by a de-coder 29 will apply the input pulse to counter 22 in addition to that derived from monostable 15. Thus during severe icing conditions, these extra pulses compensate for errors occurring due to ice building up during periods of de-icing. The output of decoder 33a may be connected via a pulse and latch circuit 35, 36 with a solenoid switch 37 which may initiate heating of the surface at a predetermined count or may supply pulses to a further counter. A comparator 28 having inputs from the counter 20 and the de-coder 26 is provided to cause the counter reading 20 to be readout without resetting to the store 30 via a logic means 32 to amend the indication at 31 if the rate of icing changes.

Class 20(1) [Also in Group XXXII] A bearing for a bridge or gantry girder comprises plates interleaved with, and bonded to, rubber 1. The plates 2 may be of steel, laminated wood, plastics, or fabric. Holes 3 in the rubber 1 extend into the uppermost plate 2 to accommodate dowels rigid with the bridge. Similar holes 4 accommodate pegs carried by the support. Holes 4a in the plates 2 accommodate flow of the rubber under load. Two bearings B (Fig. 2) may be disposed in V-formation between the support 7 and a girder 5. This prevents lateral rectilinear movement of the girder 5 but permits limited longitudinal movement and lateral rocking movement. A further pair of bearings B (Fig. 6, not shown) may be disposed at right angles to the bearings B shown, to prevent longitudinal movement. The two bearings B of Fig. 6 may be combined in a single bearing of V or arcuate shape in cross-section (Figs. 4, 5 and 7, not shown). The arrangement of four bearings may be replaced by a single bearing having plates of part-spherical shape. The top and bottom plates may be thickened as necessary to provide flat horizontal bearing surfaces.
