Patent GB-606324-A (GB)
Title: Television system for transmitting and receiving pictures in stereoscopic relief
IPC: H04N7/171
Filed: 1946-03-01
Abstract: 606,324. Television. FARNSWORTH TELEVISION & RADIO CORPORATION. March 1, 1946, No. 6470. Convention date, March 29, 1945. [Class 40 (iii)] A stereoscopic television system comprises means for periodically reversing at a predetermined frequency the polarity of successive groups of picture signals produced in a picture signal-generating tube, means for reproducing a television picture from said groups of-picture signals and means for displacing the reproduced images due to groups of signals of one polarity with respect to those due to groups of signals of opposite polarity. The polarity reversal of the picture signals developed across the load resistor 23 of an electron-multiplier 5 associated with the image dissector tube 1, Fig. 1, is effected by applying to an electrode 10 of the multiplier keying voltage pulses from generator 27 which alternately vary the potential of the latter electrode with respect to the final multiplier stage 8. The signals thus produced are transmitted in conventional manner by means of transmitter 32. The relative displacement of the two groups of picture signals, necessary to produce a stereoscopic result, is effected at the receiver, Fig. 3, by supplying the horizontal deflecting coils 91 (or the vertical deflecting coils) with a current pulse, superimposed on the normal scanning waveform, during alternate field scanning cycles. These current pulses comprise symmetrical square wave-pulses 101 developed by a multivibrator 100 under the control of rectangular pulses 98 produced by a differentiating amplifier 96 fed with saw-tooth waves from the fieldscanning generator 94. In place of the above receiver arrangement a conventional receiver may be employed and the necessary image dis. placement effected at the transmitter. An alternative method of producing the image displacement comprises means for keying either the vertical or horizontal synchronising ,pulses so that the time delay between the beginning of each blanking pulse and the beginning of each synchronising pulse changes at a predetermined frequency, Fig. 2 (not shown). As applied to the transmitter, these means include the circuit 45, Fig. 1, in which horizontal synchronising pulses from a generator 18 are fed to valves 47, 48 arranged to conduct alternately under the control of keying pulses from the generator 27, a delay network 70 being included in the output circuit of valve 47 to effect a predetermined delay to the horizontal synchronising pulses which are then fed to the horizontal scanning generator 16. Instead of the electron-multiplier keying arrangement for reversing the polarity of the successive groups of picture signals a reversing amplifier in which the number of stages is varied at the required frequency may be employed.

Title: Improvements in or relating to the Manufacture of Frames for Bags and the like, and Apparatus therefor.
Inventor: DRESDEN GEORGE
IPC: B21D53/74
Filed: 1917-05-18
Abstract: 115,874. Dresden, G. May 18, 1917. Hinges and pivois. - In making frames for ladies' hand-bags &c., two equal lengths C, Figs. 9 and 10, of channel-section metal first have their side walls flattened at the ends to the plane of the bottom of the channel, the laterally-projecting portions thus formed being shaped and pierced, those at the end of one piece for the left hand and those of the other for the right hand; the two lengths are then placed side by side, as shown, with the pierced portions overlapping, and united by hinge-rivets C<2> with washers C<3>, and, finally, the lengths are bent simultaneously, in one or more stages, to the desired shape. Each channel-strip is first placed on a die B, Fig. 4, between guide-plates B<1>, with its end butting against a stop, and a punch A is moved down so that inclined faces A<1> on it force the side walls of the strip outwards, as shown, while, at the same time, the side walls are sheared by sharp edges on the punch and on the guides B<1>. The channel-strips are treated in this manner at each of their ends, and are then acted on by the devices shown in Fig. 6 and 7. The partly-flattened end C<1> of a strip is passed into a recess E' in a die E and beneath the plate E<4> secured therto, the side walls of the strip being directed downwards in a groove E<6> closed at one end and the edges of the end C<1> abutting against the edge of a hole in the die E; this hole and a hole E' in the plate E<4> serve to receive a punch D, shaped as shown in cross-section in Fig. 7 and constructed with an inner punch D<2> adapted to enter a corresponding hole in the die E. The punch D, on descending, completes the flattening of the end C<1> and shears it to produce a hingemember of the required shape, and also punches the rivet-hole. This operation is repeated at the other end of the channel-strip, but with side wails thereof disposed upwards in a groove E<7>. Two strips thus treated are, after being coupled as shown in Figs. 9 and 10, laid on a die-plate U, Fig. 12, secured to a die-body G<2>, with their ends abutting against a stop-plate K carried by bolts and nuts on a bracket J, slots in these parts permitting horizontal and vertical adjustment of the stop-plate. The strips are gripped against the body G<2> by a vice-plate G<3> carried on the body by two dowel-pins and moved up, against the action of a spring G<5>, by an eccentric piece H turned by a hand-lever. The die-plate G coacts with two dies F separated by a plate F<2>, these dies being arranged to enter the two channelstrips and, by reason of a right-angle or other formation of the dies of the die-plate G, serving to bend the combined channel-pieces to the required extent. Additional dies may be used for curving or otherwise shaping the outline at the top of the bag. According to the Provisional Specification, a die with a single plate may be used, coacting with a thicker die-plate and adapted for binding a single channel-strip.
