Title: Improvements relating to the remote control of radio apparatus
Inventor: GARGINI ERIC JOHN
IPC: H03J9/00
Filed: 1953-09-16
Abstract: 765,968. Radio receiving apparatus ELECTRIC & MUSICAL INDUSTRIES, Ltd. Sept. 16, 1954 [Sept. 16, 1953], No. 25563/53. Class 40(5). A television receiver is provided with remote control of contrast and sound volume by means of the tuned circuits 20, 21, which operate by re-radiation of direct pick-up from the receiver and together provide a control unit 2 having no direct connection with the receiver. The circuits 20, 21 are tuned respectively to the second and third harmonics of the linescanning frequency and, by varying their tuning can be made to modify the currents flowing in the loop 5 in a, desired manner, these currents then being employed in the receiver to effect the desired controls. The loop 5 is excited directly from the receiver both by energy supplied from the coil 3 which is coupled to the line scanning circuits and by direct pick up from these circuits, and is also excited by re-radiation from the unit 2. The relative amounts and phase of these separate energy contributions are such that when the circuits 20, 21 are tuned precisely to their respective harmonics no current flows in the loop; however, on altering the tuning the energy reradiated from. the tuned circuit is altered in phase and a control current of the appropriate harmonic frequency flows in the loop. Signals of twice the line scanning frequency are selected by the tuned circuit 6 and applied to the amplifier 8, 12. Gating pulses 17 of twice the line scanning frequency are applied to the supressor grid of the pentode 12; hence an output whose amplitude and sign varies with the extent and direction of the phase variation of the signal re-radiated by the circuit 20 from its mean value is developed at 16. This output is used to control the contrast of the reproduced picture. Similarly a signal of three times the line scanning frequency is developed across the tuned circuit 7 and is used to develop a signal from control the amplitude level of the reproduced sound. Similar arrangements may also be employed for controlling gamma.

Abstract: 978,173. Facsimile telegraph systems. MUIRHEAD & CO. Ltd. May 13, 1963 [July 4, 1962], No. 25675/62. Heading H4F. In a facsimile system for reproducing in a receiver pictures from a plurality of transmitters the time for each line scan in the receiver is arranged to equal the sum of the time of line scans in the transmitters and each transmitter is connected in turn to the receiver for the transmission of one line. As described, two transmitters A and B are connected alternately by a polarized relay 16 via a transmission channel 26 to a receiver C. In each transmitter an electro-optic scanner moves along a rotating drum so that one helical line is scanned during each rotation. In the transmitter A, the drum 1 drives a two-to-one reduction gear 5, 6, connected to a two-segment commutator 8 which operates the relay 16. To the contacts of this are connected the respective scanners 3, 3<SP>1</SP>, of the transmitters A and B, the drums of the two transmitters being maintained in phase by known means, so that the two scanners are alternately connected to line and each transmits each alternate line of information scanned. The two images received are reproduced side-byside to a reduced scale by driving the recording helix 29 at half the speed of each of the drums. It is mentioned that the arrangement may be applied to other types of facsimile system, e.g. " flat bed " types employing linear scanning, and more than two transmitters may co-operate with one receiver.

Title: Improvements in weft-cutting means for automatic weft-replenishing looms
IPC: D03D49/70
Filed: 1923-10-17
Abstract: 223,731. British Northrop Loom Co., Ltd., and Hollins, D. M. Oct. 17, 1923. Weft, cutting.-In an automa,tic weft-replenishing loom, the weft ends extending to the selvage are out on the pick immediately after that on which bobbin transfer occurs by means of a cutting blade h<1> on a spring-controlled bar h slidable in guides f on the temple stand. The bar h is normally held in a rearward inoperative position by a fixed catch f<1> engaging a notch h<2>. When the bobbin transfer shaft r is rocked, an arm s is moved to the left, displacing a latch o, which is pivoted to the bar h and is held against a stop k by a spring p. When the arm s returns to normal position, it acts on the bevelled front face o<2> of the latch, and thereby raises this and the bar h against the action of a spring m. The bar h is thus freed from the catch f<1> and is moved rearwardly by its spring i into the position shown in Fig. 2. An adjustable abutment screw u<3> on a lever u embracing a stud &c. t on the bar h is thereupon engaged by a cam-controlled lever w, and the bar h is moved frontwardly to cut the weft ends. The bar h is thereafter retained in inoperative position by the catch f until transfer again occurs, the screw u<3> on the lever u being out of the range of the constantly-moving lever w. The temple thread-cutting mechanism is thus operative for one pick only. The cutting-blade h<1> co-operates with a fixed cutting blade.
