Filed: 1955-06-03
Abstract: 772.575. Television. PHILCO CORPORATIONJune 3, 1955 [June 3 1954] No. 16000/55. Class 40 (3). In a colour television receiver of the kind described in Specification 745,353, in which indexing signals derived by scanning a series of indexing stripes with a first electron beam modulated at a pilot frequency are employed to control the relationship between the phase of a colour modulated subcarrier wave, which modulates a second electron beam scanning (synchronously with the first beam) a colour-producing screen, and the position of the second beam on the screen, the intensity of modulation of the first beam being sufficiently low so as not to produce desaturation of the colours produced by the first beam, spurious signals mixed with the indexing signals and the intensity of which vary directly as the intensity of the colour modulating signals are maintained at a low level relative to the level of the indexing signals by varying the intensity of the pilot modulated beam in accordance with the intensity of the video signal. Fig. 1 shows one arrangement for carrying out the invention in which the indexing beam, which is controlled by electrode 18 and modulated by a signal from pilot oscillator 54, is further controlled in intensity in accordance with the L.F. components of the video signals derived from adder 72 via low-pass filter 82. In an alternative manner of carrying out the invention the pilot oscillator itself may be modulated by the output of filter 82. Specifications 753,447 and 759,386 also are referred to.

Title: Improvements in or relating to routining equipment as used in telephone systems
Inventor: HOPLEY HORACE EDWARD
IPC: H04Q1/24
Filed: 1949-06-16
Abstract: 669,367. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. May 30, 1950 [June 16, 1949], No. 16032/49. Class 40 (iv). Whenever a routiner discovers a fault, one of a number of counting devices operated each time connection is made to a different piece of equipment under test is disconnected to provide a record of the location of the fault, the test then being continued. Similarly where a routiner makes a number of tests on the same piece of equipment, the type of fault may be recorded. An access switch is provided for each rack of, e.g. group selectors, and is seized by the routiner over a primary distributer, both switches being of the 100-outlet two co-ordinate type. When the start key KS is thrown, control equipment steps the distributer to the access switch of the rack to be tested. Each time the distributer steps a relay DS (not shown) operates a group of counting clocks RM1 ... RM12 having number indicators and connected in pairs in series between the normal exchange battery (50 volts) and a similar battery having its negative pole earthed. Similarly, a relay TF (not shown) and clocks PM1 ... PM12 are operated when an access switch steps. The clocks may be as described in Specification 413,000. When a fault is discovered or when after encountering a busy group selector a predetermined time elapses, relay TB (not shown) steps a uniselector FT so disconnecting the clocks PM1, RM1. The location of the fault is thus shown by the numbers on the clocks PM1, RM1. Relay TB also earths lead 11 to signal the routiner to continue the test. The operation of FT in response to the finding of further faults disconnects one from each group of clocks. When the sixth fault occurs relay NA operates and when the twelth fault is found relays FN, TB earth lead 10 to actuate an audible alarm. The uniselector FT is homed by the closure of key KS. The clocks are homed as a group by means of a key or alternatively they are homed individually by reset buttons. Specification 654,134 is referred to.

Abstract: 959,686. Beam-type parametric amplifiers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 5, 1962 [May 4, 1961], No. 16215/61. Heading H1D. A radio-frequency amplifier comprises an input coupler in which an input signal is applied to an electron beam in the presence of an axial magnetic field to produce a cyclotron wave motion in the electrons of the beam, an amplifying section, e.g. as shown in Fig. 2, in which this wave motion is amplified by interaction between the electrons and a spatially periodic electrostatic field provided by a series of electrodes 12, 13, 14, spaced apart along the beam which electrodes define slot-like apertures and alternately in succession along the beam are charged alternately to potentials above and below the potential of the beam and through which apertures the beam passes at a velocity such that the transit time taken by an electron to traverse one wavelength of the electrostatic field distribution equals half the period of the cyclotron frequency of electrons in the axial magnetic field, and an output coupler in which the amplified wave motion of the electrons produces an amplified output signal. Each slot-like aperture is an opening in a separate plate or, as shown, a gap between two plates, strips or rods. The input circuit may be two plates; at higher freqiencies a resonant waveguide or a travelling wave structure may be used. The beam is circular or rectangular in cross-section. By rounding the ends of the electrostatic field electrodes a sinusoidal variation of potential is.obtained along the beam axis. The transverse spacing of rod-like electrodes can increase along the length of the structure. The transit time may be maintained constant by (a) an accelerating bias along the whole length of the structure, (b) shorten the axial length of successive periods of the structure, (c) progressively reducing the magnetic field. The magnetic field may be smaller over the length of the couplers than over the amplifying section.

Title: Improvements relating to ticket cancelling machines
IPC: G07B11/09
Filed: 1937-06-12
Abstract: 496,900. Ticket-cancelling machines. FISHBURN, J. E., and WARD, A. W. June 12, 1937, No. 16335. Addition to 479,546. [Class 106 (iii)] In a ticket-cancelling machine as described in the parent Specification. a ticket strip is fed to severing mechanism within the machine which severs the ticket longitudinally at a position intermediate its side edges, one of the sub-strips so formed being subsequently ejected from the machine. The other sub-strip is stored in a container in the bottom of the casing 31 of the machine. The operating mechanism is mounted on plates 52, 53 and 54 and driven by an electric motor 44. The ticket is passed into the machine through an aperture on top of the casing 31 and presses down a lever 59 thereunder releasing the latter from a catch 60. A spring 64 then rotates the lever assemblage 59, 61, and 63 and closes contacts 73, thus starting motor 44. A pin 66 on a disc driven by the motor returns the levers to the inoperative position after a determined interval. The strip then passes through feed rollers 56 and 57 to a fixed guide carrying a pivoted member 76. If the strip is of double thickness the front end of member 76 is raised to such an extent that the rear end prevents the passage of the strip. A similar stopping member is mounted on an arm 80 and serves to prevent operation of the machine by a half width ticket strip. This member is situated in one half of the width of the path of the ticket and the arm 59 is in the other so that both devices cannot be actuated together by a strip of width less than the standard. The strip then passes through printing rollers 85 and 86. These mark the ticket with the name of the day and an indication as to whether it is morning, afternoon, or evening. The printing rollers are removable in order that the indications may be changed. Beyond the printing rollers is arranged a toothed or knurled wheel 95 which drives a counter 99 indicating the number of tickets that have passed through the machine. The strip then passes to cutting rollers 120 and 124 having overlapping cutting edges after which guides lead one half of the ticket down to the container and the other half is ejected through an opening at the front of the machine. The serial number of a ticket is arranged at each end thereof in such a manner that each half ticket bears a sufficient part of each number to identify the whole number from one half ticket.

Filed: 1958-04-21
Abstract: 853,329. Correspondence control devices. ULTRA ELECTRONICS Ltd., [formerly ULTRA ELECTRIC Ltd.]. April 17, 1959 [May 21, 1958], No. 16337/58. Class 40 (1). In a transducer utilizing either the Hall effect or the magnetoresistive effect, a semiconductor lamina is embedded between two high-permeability semicylindrical members 1, and spaced from the circumference and ends thereof, and the cylindrical rotor thus formed is mounted between the poles 2 of a magnetic circuit so as to be rotatable about its own axis. The Hall voltage output, or the semi-conductor resistance, depends upon the magnitude of the component of magnetic flux normal to the lamina, i.e. upon the angular position of the rotor. Preferred semi-conductor material for the lamina is an alloy of elements of Group III and Group V of the Periodic Table, e.g. indium arsenide or indium antimonide. When Hall effect is utilized, the transducer output, which passes through zero and is bidirectional, may be connected in opposition to an external signal source, e.g. a thermocouple, to produce a differential control signal. When the magnetoresistive effect is used, the semi-conductor lamina may be connected in a bridge circuit comprising a similar lamina; this arrangement gives a null output at zero setting with temperature compensation. The cylindrical rotor produces a sinusoidal output; if an output with an extended linear portion is required, the shape of the rotor may be modified, or a suitable mechanical link or cam arrangement may be used.
