Title: Improvements in aerial systems employed in wireless telegraphy and telephony
IPC: H03H7/01
Filed: 1919-08-14
Abstract: 155,330. Franklin, C. S. Aug. 14, 1919. Aerials; directive wireless signalling.-An aerial A is tuned by variable inductance I and capacity C at a distant point, which may be a considerable fraction of a wave-length away, the aerial being coupled to the connecting-circuit B by a transformer 1. The connecting-circuit may include other transformers 2, 3. This arrangement is employed for directional working by a system of spaced aerials, when it is desirable that all the aerials should be tuned at the same place. The transformers 1, 2, 3 prevent the aerial A and circuit B from oscillating as a long horizontal aerial. An earthed shield is preferably interposed between the windings of each transformer. The transformers should have small leakage and small capacity between the windings or to earth, and the inductance of each winding should be large compared with that of the aerial.

Filed: 1971-04-19
Abstract: 1331141 Pneumatic timing devices BROOK. HIRST IGRANIC Ltd 19 April 1971 [18 Feb 1970] 20311/71 Heading F2S [Also in Divisions G3 and H1] A pneumatic timing device 2 comprises an expansible chamber 56, and means for controlling the rate at which air enters it comprising a valve member 64, Fig. 3, having a groove 72 formed in its external surface and having a passageway 74 communicating with the groove and with the chamber, and means 90 operable to progressively dispose a sealing means 80 over the groove to form a timing passage of increasing length "L" to decrease the rate at which air may pass therethrough to enter the chamber. The V-groove 72 is rolled into the body 64, leaving slight ridges on the surface. Rotation of a dial 84 carrying the roller 90 adjusts the distance "L". The device is combined with a solenoid 4 and a snap-action switch 8 as in Specification 886,253. The plunger 12 of the switch 8 is shown depressed by a lever 14 straddling a cup 18 connected to a plunger 20 secured to a washer 22 moulded into a diaphragm 24. The cup 18 is urged downwardly by a spring 44 and contains a spring to bias downwardly a further plunger 28 to engage an armature 36. The armature 36 can be retracted against a spring 42 by energizing a coil 32. The coil 32 is retained by a spring 34. In operation, when the solenoid 32 is actuated, the armature 36 is retracted away from the plunger 28. The spring 44 then moves the cup 18 downwardly at a rate controlled by the flow of air through the groove 72 which allows the diaphragm 24 to move until the lever 14 releases the switch 8. When the solenoid is released, air flows round the upper surface of the diaphragm to escape through the passages 58, 60, as in USA Specification 3,040,842.

Filed: 1951-08-30
Abstract: 717,044. Escapements. NORTH THAMES GAS BOARD. Oct. 22, 1952 [Aug. 30, 1951], No. 20517/51. Class 139 [Also in Group XXIV] In an anchor-type escapement mechanism particularly applicable to a flow meter for a gas heated calorimeter of the kind described in Specification 333,292, [Class 139], the anchor is formed in two articulated parts 4, 6, the part 4 pivoted at 5 and carrying the exit pallet 2 and the part 6 pivoted at 7 to part 4 and carrying the entry pallet 3 for co-operation with the escape wheel 1. The part 4 carries an armature 8 under control of an electromagnet 11 and a spring 12 acts upon a pin 14 on the armature 10 to maintain the parts in the position shown. In this position the pallet 3 engages the wheel to lock it from rotation. On energization of electromagnets 9 and 11 the pallet 2 moves into engagement but the entry pallet 3 merely rocks at first without disengaging from the wheel. As, however. the armatures 8, 10 approach their magnets the pallet 3 is disengaged by a strong magnetic pull but the wheel is prevented from rotation by the engagement therewith of the pallet 2. On de-energization of the magnet the wheel 1 is released by the pallet 2 and moves round a 'step until the pallet 3 engages the next tooth. In its initial movement the angle of the locking face of the pallet 3 changes so that the pressure exerted by the wheel tooth assists in the disengagement from the wheel.

Abstract: 1,165,978. Measuring eccentricities electrically. R.R. BUTTERS and K.A. ROLLIN. June 18, 1968 [May 4, 1967], No.20677/67. Heading G1N. In the measurement of the eccentricity of a member rotating about a fixed axis, the diameters of the member in two positions are sensed using similar inductive transducers A, B, Fig. 1, each comprising an anvil 3 in contact with the surface of the member and magnetic core of a differential transformer in contact with a diametrically opposite point. The supports for each anvil and differential transformer are mounted together on a floating caliper 2 or 4 so that the anvil is free to move with effective changes in radius of the member (due either to an overall increase in radius or eccentricity of the member), movement of the anvil causing corresponding movement of the differential transformer relative to its core, so that the total relative movement of core and anvil corresponds to the diametral change. The two calipers also have mounted on them supports, one for a differential transformer and the other on which its core rests so that relative movement between the two calipers is indicated by change in inductance of the transformer; these changes can be shown to be equal to the difference of half the diameters sensed by the two transducers A and B Œhalf the difference of the eccentricities sensed. Each transducer is connected to a D.C. excited solid state oscillator, a phase-sensitive demodulater whose output represents the relative displacement of coil and core and which is fed to a buffer amplifier provided with output terminals 6, 8, 10, the voltage across these terminals being indicative of #¢ input displacement respectively. To provide a measure of the relative eccentricity of the member the output from the buffer amplifier connected to transducer C has subtracted from it the outputs from the buffer amplifiers connected to transducers A and B. To provide an indication of maximum material conditions, the output from the amplifier connected to transducer B is added to the output of the buffer amplifier connected to transducer C to provide a signal indicative of the sum of the two diameters measured and their relative eccentricities.

Abstract: 491,999. Indicating proximity of the earth. SIEMENS APPARATE UND MASCHINEN GES. July 27, 1937, No. 20800. Convention date, July 27, 1936. [Class 37] [Also in Group XL] For measuring the altitude of an aeroplane by the time taken for a transmitted wave to be reflected back from the earth, the transmitting and receiving aerials are arranged parallel to each other and to the wings of the machine, and are so divided and spaced apart that the receiver is decoupled from the transmitter. As shown, the receiving aerial is in two parts E1, E2 arranged on opposite sides of the transmitting aerial S, one part E2 being spaced one wavelength away whilst the other E 1 is half a wavelength. Direct pick-up from the transmitter is therefore in phase-opposition and does not affect the receiver. The differences in amplitude are equalized by adjusting the transformer T, or the Lecher-wire coupling R to the receiver. In modified arrangements both parts of the receiving aerial are located on the same side of the transmitter and spaced a half-wave apart; or the arrangement of the transmitting and receiving aerials shown in the Figure may be transposed.

Abstract: 1,211,408. Telephone exchanges. INTERNATIONAL STANDARD ELECTRIC CORP. 2 May, 1968 [5 May, 1967], No. 20880/68. Heading H4K. In a telephone exchange system adapted to connect wired substations in ordinary exchanges to mobile substations at unknown points in an area covered by a plurality of radio exchanges, a transmission link interconnects all the exchanges and is used to transmit only service information. As shown wired subscribers such as 6 send the number of a wanted mobile, which as shown is a car 3 on a road 1, to a toll exchange 5 which seizes the transmission link 7 and transmits this number to all radio exchanges 2 which each broadcast the number over their radio links. The mobile equipment may be a simple call receiver which merely alerts the mobile subscriber, in which case the transmission link can be released, or may be a complete transceiver in which case the exchange 5 hold the transmission link 7 until one of the radioexchanges, in response to an acknowledgement signal from the mobile subscriber, sends its own identity over the transmission link to the exchange 5. The exchange 5 then releases the transmission link and establishes a connection to the answering radio exchange over the normal switching chain. Various arrangements are outlined. In one form the connection over the normal switching chain proceeds as a fresh call to a mobile known to be associated with a particular radio exchange, this exchange again broadcasting for the wanted mobile. In another form the radio exchange holds the path used to connect to the mobile and transmits both its own identity and the identity of a link in the normal switching chain on which a call is to arrive from the toll exchange 5, over the transmission link. When the call is established to this link ringing of the mobile is automatically initiated. In other forms, each mobile subscriber is associated with a wired line circuit in the radio equipped exchange and a connection is made simultaneously to the mobile subscriber and this line circuit which is used for metering purposes &c. P.B.X. hunting of such wired terminal equipment is also suggested.
