Abstract: 644,608. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Sept. 26, 1947, No. 26138. Convention date, Sept. 26, 1946. [Class 40 (iv)] [Also in Group XL (c)] In an automatic exchange system of the type described in Specification 644,571, in which speech signals are transmitted in both directions simultaneously over the same distributer and wherein the outgoing signal consequently appears as an unwanted signal on the incoming lead, a portion of the outgoing signal is fed directly to the incoming lead and so phased as to neutralize the unwanted signal. As shown outgoing amplitude-modulated signal pulses S(s) are directed to appropriate subscribers connected to secondary emission electrodes e by grid modulation of the beam of the distributer D. Incoming signals from the subscribers modulate the secondary emission from the electrodes e to produce pulses W (a) in the incoming lead, wherein variation of the secondary emission due to the outgoing signal S(s) also produces an unwanted pulse component W(ks). A portion of the outgoing signal is fed to the valve V in opposition to the unwanted component so that its output contains the incoming signal pulses Z(a) only. Should the unwanted signal bear a non-linear relationship to the outgoing signal a network of compensating non-linear resistances may be included in the connection between the outgoing lead and the valve V.

Title: An improved method of recording profiles and traverses in surveying and the like and apparatus therefor
IPC: G01C7/02
Filed: 1921-10-06
Abstract: 191,437. Williams, J. H. Oct. 6, 1921. Road-contouring apparatus; course-recording apparatus. - To avoid the use in the field of delicate recording apparatus such as that described in Specification 168,125, a preliminary record or curve showing a trigometrical function,. such as the sine, of the angle between the contour or course and an element maintaining a fixed direction such as a pendulum or compass, is prepared in the field, and this record or curve is used to determine the movement of the first motion spindle of the main recording apparatus. Figs. 1 and 2 show apparatus for obtaining the preliminary record in road-contouring. The record paper is drawn by a drum c from a feed roller j and passes over a table e under a stylus f fixed to an arm g secured to the shaft h of a pendulum i, and the paper passes from the drum c over a roller k to a receiving roller l. The drum c is driven from a shaft d driven from the road wheels of a two-wheeled carriage carrying the apparatus. The roller l is driven through belting from the drum c by way of the roller k so as to have the same peripheral speed as the drum, one of the transmission pulleys m being fitted with a friction drive to allow slip as the roll on the roller l increases in diameter. To cbtain a considerable movement of the stylus for a small change of slope when the initial slope inconsiderable, the stylus on one or other of two additional arms g on either side of the main arm g may be used. The preliminary record having been obtained, the shaft d is geared at d<1>, Fig. 7, to the main driving shaft G of the recording apparatus, and the shaft h is geared to the pendulum shaft of this apparatus. This pendulum shaft is fitted with an arm p carrying a pointer p<1> and a handle. The shaft d is rotated by a handle d<2> while the pointer p<1> is made to follow the line of the preliminary record and the apparatus thus records a true profile of the course. Fig. 8 shows apparatus for obtaining a preliminary record in course-recording. A sphere A, secured to a shaft driven from the road wheels, drives frictionally a wheel C carried by an arm of a pendulum K pivoted at I, the axis of the pivot being in line with the centre of the sphere. The rotation of the wheel C is transmitted to light-sensitive record paper which thus has a movement proportional to the horizontal distance travelled. A compass card E mounted above this paper carries a mirror F which reflects light from a source H through an aperture in the card on to the paper.

Abstract: 1468825 Data transmission-PSK systems POST OFFICE 6 June 1974 [6 June 1973] 26979/73 Heading H4P A phase modulator for use in a differentiallycoded, phase shift keyed system comprises S independant data stores FF1, FF2, e.g. gated flip-flops, for synchronizing streams of serial binary data D, D, E, E to clock pulses and for storing the synchronized binary data for one clock interval, a delay line G2-G5 for deriving N phases of the carrier signal F for an N-phase system and logic gates G6-G9 for selecting any one phase of the carrier signal F in accordance with the input data, there being log 2 N streams of binary data in an N-phase system. In operation, the carrier signal F is applied via a voltage level setting circuit C, R 1 , R 2  to an OR/ NOR gate G 2  to form two signals differing in phase by 180 degrees. Then on-phase shifted signal is applied to further NOR, OR, OR/NOR gates G3, G4, G5 to produce two further signals differing from it by 90, 270 degrees respectively. Selection of the required carrier phase is by logic gates G6-G9 in which the four possible permutations of D and E selects one of the phases so that only one phase appears via OR gates G10, G11. Signals D, E may be from an encoder or other digital signal equipment. The outputs of NOR gates G6-G9 along with the phase shifted carrier signals may be applied to a threshold diode-resistor logic (Fig. 2, not shown) when the carrier frequency is higher than the maximum operating frequency of gates G6-G9.
