Title: Radio navigation system
Inventor: FERNAU FRANCIS GEORGE GUY
IPC: G01S1/02
Filed: 1964-07-10
Abstract: 1,113,439. Radio navigation. STANDARD TELEPHONES & CABLES Ltd. 9 July, 1965 [10 July, 1964], No. 28644/64. Heading H4D. In an aircraft radio navigation system, the position of the aircraft is determined relative to a flight corridor, by means of two systems of isophase hyperboli, frequency modulated waves being used and the difference in the received frequencies giving the path difference. The path of an aircraft 8, Figs. 1 to 3, emitting the wave over paths 10 and 11 may be monitored relative to a vertical runway plane 1, having aerials 4 and 5 either side thereof, feeding a receiver 2. Where the transmission lines 6 and 7 are of equal electrical length, location of the aircraft on plane 1 is shown by equal frequency of the received frequency, or a zero frequency of a beat frequency signal produced in the receiver. Where the transmission lines are not of equal length, location of the aircraft on the plane is shown by a beat frequency of constant predetermined value. The former situation indicates when the aircraft deviates off the plane, whilst the latter situation also indicates the sense of the deviation. Each edge of the runway (and lateral limits of said corridor) may be defined by a vertical plane 1 or 1A, Fig. 4, resulting from the two aerial pairs 4/5 and 4A/5A. Other beat frequencies may define hyperbolic planes H and H A , and an alarm may be sounded if the beat frequency signals produced in receivers 2 and 2A, indicate that the aircraft is not in the flight corridor above the planes H and H A  and between the planes 1 and 1A. Planes H and H A  may each be replaced by a pair of planes Hp/Hq and Hm/Hn, Fig. 5, such that a tunnel flight corridor is defined from their intersection, having a circular shape along the line of the runway, Fig. 6. Beat frequency signals produced at the receivers, can actuate an alarm when the aircraft is outside of the tunnel. If one of the aerial pairs is tilted the tunnel assumes the shape of Fig. 7. The transmitter, aerials and receiver may be at the same place, the transmission paths being completed by reflection from the aircraft, or the aerials may be replaced by reflectors, and the transmitter and receivers mounted in the aircraft.

Title: Improvements in or relating to electric signalling systems
IPC: H02J13/00
Filed: 1930-09-25
Abstract: 363,427. Electric signalling systems. SIEMENS - SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. Sept. 25, 1930, No. 28773. Convention date, Oct. 2, 1929. [Class 40 (i).] In a system for supervising the condition of apparatus units, e.g. cirouit breakers, wherein upon a change in position of a unit an alarm signal is given and is then switched off by the supervisor, arrangements are made whereby in the event that several alarms are operated corresponding to the changed condition of several apparatus, the alarms may be switched off by common operating means. As shown in Fig. 1, a polarized relay 4 takes up a position corresponding to that of the associated apparatus. When the apparatus changes position, relay 4 closes the circuit of relay 8, over contacts 6, and switches 14, 19 to actuate switch 10 and switch alarm lamp 16 into the circuit of a flashing device 17. The alarm may be nullified either by reversing the switch 14 and associated position indicator 15 by hand or by depressing switch 19 to de-energize relay 8 and thereby effect reversal of switch 14 through the medium of the pawl and ratchet wheel 12, 13. The switch 19 is common to a plurality of apparatus so that in the event that several alarms are given, the alarms may be nullified and the position indicators adjusted to their new positions by the operation of switch 19. In a modification the switch 19 is normally open and is adapted to control electromagnets for reversing the switch 14. The reversing switch itself may form the position indicator and may control signal lamps. The position indicators which may be illuminated by the lamps 16 may be embodied in an illuminated circuit diagram. In the modification shown in Fig. 3, the condition of the circuit breaker is indicated on a circuit diagram by the illuminated or unilluminated condition of corresponding sections 34, 35. Illumination of sections 32, 33 representing feeders also is dependent upon the switch positions. When the switch corresponding to section 35 moves to its " closed " position, relay 42 is operated over lead 44 to (1) illuminate section 33, (2) open the holding circuit of relay 41 and effect its release, (3) operate the locking relay 46, and (4) complete the circuit of a flashing device 61 for section 35. The alarm signal may then be switched off by operation of switch 19 which releases relay 45 to complete a circuit for the constant illumination of the section 35. Similarly movement of a circuit breaker into its " open" position operates relay 41 which switches the appropriate indicating section into the flashing circuit whereupon operation of switch 19 effects release of relay 46 to open the flashing circuit and render the indicating section dark. Switches similar to 19 may be provided individual to each apparatus or to groups of apparatus.

Abstract: 1,268,624. Automatic exchange systems. POST OFFICE. 19 June, 1969 [19 June, 1968], No. 29237/68. Heading H4K. A monitoring equipment (e.g. for telephone switchboards) comprises means operative during periodic intervals to count the number of demands for service in each of those intervals, means to measure a variable characteristic of the number of staff available during each interval and means to display a signal derived from the two measured statistics. As described a supervisor sets a pulse generator (comprising a uniselector stepped through a variable number of steps and arranged to produce an output pulse once per cycle) to produce a pulse say every 120 seconds the rate being varied in accordance with the current mean time to answer an incoming call. A pen recorder which normally records the number of operators who have their headsets plugged in, is switched for a period of 6 seconds in response to each pulse to record the number of new calls initiated since the last pulse. The retard coil in each operator's headset is fitted with a make contact which is closed when the headset is plugged in connecting current via an associated resistor to a common input to the pen recorder to provide a measure of the number of operators in position. Two uniselectors are used alternately to count the number of new calls between successive pulses and while one is counting the other is associated with the pen recorder and has one bank which selects a tap on a potentiometer supplying current to the recorder during a 6 second period to give a measure of the number of new calls. With suitable scaling the ideal curve produced is smooth, deflections above and below indicating under- and over-staffing respectively. The total number of calls waiting may also be recorded on a pen recorder.

Abstract: 909,432. Type-bar-making machines. MERGENTHALER LINOTYPE CO. Aug. 25, 1960 [Sept. 2, 1959], No. 29351/60. Class 100 (3). Trimming type-bars.-A typographical linecasting machine having a knife block adjustable to a slug-trimming position and to an open position to allow slugs with type-bearing overhang portions to pass through comprises means operable when a matrix line is in the assembler elevator to store a " knife block open " signal, received from a control tape or from a manually controlled push-button, means operable when the line is transferred to the delivery slide to transfer the signal to a second storage stage, and means operable when the line is delivered to the first elevator to actuate the knife block. Receipt of the signal closes a switch 70, Fig. 4, or a switch 32, for automatic or manual operation respectively, to energize a relay A and complete a holding circuit therefor. When the assembler elevator is raised, a switch 31 is actuated to close contacts 72, 73 and energize a relay B1 and thereafter to open contacts 72, 71 and release the relay A1 a holding circuit for the relay B being completed through a normallyclosed switch 37. When the line delivery lever 64, Fig. 2, reaches its fully advanced position, a collar on a rod 63 closes a switch 36 to energize a relay C in series with a resistor 74, a holding circuit being completed through the relay contacts C1, and contacts B3 being open. Thereupon, contacts C2 are closed, and a reversible motor 53 is actuated to raise a rod 46 and move counter-clockwise a lever 42 to open the knife block 40. A roller 56 on the rod 46 allows a limit switch 54 to close and opens a limit switch 55 to stop the motor. Return movement of the rod 63 opens the switch 36, and also the switch 37 to release the relay B. If the next line is also accompanied by a " knife block open " signal, the relays A, B are again energized, the relay C having remained energized, and the rod 46 remains in its upper position. If the next line is unaccompanied by a signal, the relays A, B remain de-energized, and when the switch 36 is closed, the relay C is de-energized, being shortcircuited through normally closed contacts B3 of relay B. Contacts C3 are thereupon closed to actuate the motor 53 in reverse and lower the rod 46 to close the knife block, the switch 54 then being opened by the roller 56 to stop the motor, while the switch 55 closes. All the relays are now de-energized. Specification 556,848 is referred to.
