Filed: 1951-07-05
Abstract: 702,477. Television. HAZELTINE CORPORATION. July 5, 1951 [July 21, 1950], No. 15990/51. Class 40 (3). [Also in Group XL(c)] Relates to means for producing in the receiver of a negative-modulation television system a pulsed control voltage having an amplitude proportional to the difference in amplitude between the peaks of the synchronizing pulses and random noise pulses of greater amplitude than the synchronizing pulses, the control pulses being applied (a) to block the synchronizing pulse separator to prevent it responding to such noise pulses or (b) to the cathode-ray tube to reduce the effect of such noise pulses on the reproduced image. Blocking synchronizing pulse separator, Fig. 1. -This embodiment is described as applied to the system shown in Fig. 1 of Specification 697,820 in which the video signal is applied to the cathode of the cathode-ray tube and also via terminals 26 to the grid of a detector 30 which is gated on by positive pulses derived from the receiver line scan generator and applied via terminals 29 to the anode to produce across the R.C. cathode load 32 a positive D.C. voltage proportional to the amplitude of the synchronizing pulses, a fraction of this voltage being applied to bias the cathode of the synchronizing pulse separator 50 so that the amplitude of the separated synchronizing pulses is substantially independent of signal fluctuations, another fraction of the D.C. voltage being applied via network 65 and terminal 72, as a brightness control voltage to the grid of the cathode-ray tube to stabilize the black level of the reproduced image, and a negative A.G.C. voltage being developed across network 45. In accordance with the present invention, a rectifier 90 is shunted between a terminal 26 and the cathode of V50, the rectifier being rendered conductive only by random noise pulses of amplitude greater than the peaks of the synchronizing pulses to develop an additional bias across load resistors 43 and 64 which blocks the synchronizing pulse separator 50 and renders it unresponsive to such noise pulses. Reducing interference on reproduced image, Fig. 2.-In this embodiment the synchronizing pulse separator is omitted and the rectifier 90 is shunted between a terminal 26 and the cathode of the detector 30, the control pulses developed across load resistors 43 and 91 being applied via am amplifier 92 with positive polarity to the grid of the cathode-ray tube 17 the amplitude of the applied pulses being such as to counteract the effect of the high amplitude noise pulses in the video signal applied directly to the cathode of the cathode-ray tube. An automatic brightness control voltage is developed by the network 95. 98 similar to that shown in Fig. 3 of Specification 697,820. Suitable component values are given for the embodiments described and Specifications 623,431, [Group XL(c)], and 697,819 also are referred to.

Title: Mechanism for automatically replenishing weft in power looms
IPC: D03D45/34
Filed: 1925-06-24
Abstract: 258,659. Arima, H. June 24, 1925. Shuttle-changing mechanism. - When the handle 8, Figs. 1 and 2, is moved to the left under the action of the weft fork mechanism on the failure of weft &c., a clutch shifter 18 is operated by lever mechanism 13, 12, 10 and disengages the clutch whereby the main shaft 1 is driven from the belt pulley 5 and the normallyoperative parts of the loom are stopped, whilst a forked rod 35 is operated by lever mechanism 33. 32, 30 so as to cause a clutch member 28 on a change shaft 25 to engage a clutch member 27 on a gear 26 driven by spur and chain wheel gearing from the belt pulley. The change shaft, which is provided with four cams 41 - - 44 controlling the shuttle-changing mechanism, is thus rotated, and, after it has made one revolution, a cam 76 on a shaft 74 driven from the shaft 25 operates the handle 8 and moves it to the right, whereby the main shaft is restarted and the change shaft is stopped. As shown in Figs. 15 to 17, the cam 41 acts on a bowl on a rod 48 supporting a slidable board 50 forming the back wall of the shuttle box, which is thus raised. The cam 42 actuates lever mechanism 51, 53, whereby a pushing rod 54 is caused to pass through the front wall of the shuttle box and eject the spent shuttle from the shuttle box through a funnel 78 out of the loom. The cam 43, Fig. 2, operates a lever 56 connected by a flexible powertransmitting rod 91 to a bell crank lever 62 connected by a link to one of two shuttlesupporting members 63, which are linked to shuttle-supporting members 65, whereby a shuttle is dropped from a shuttle depository 60 on to a shuttle receiver 93 on a rod 66. This rod is loosely mounted on a shaft 20, but is connected by a spring 70 to a lever 68 operated by a cam 44 on the change shaft, whereby the rod 66 is caused to carry the fresh shuttle it supports into the shuttle box. An adjusting screw 71 limits the movement of the rod 66 relatively to the lever 68. The sliding board 50 next moves to an intermediate position as shown in Fig. 17, whilst the rod 66 moves back leaving the fresh shuttle in the shuttle box, and afterwards the sliding board moves to the lowest position.

Abstract: 570,140. Secret transmission. SHANNON, D. S. B., and CRASKE, H. Dec. 17, 1941, No. 16293. Drawings to Specification. [Class 40 (iv)] [Also in Group XL] In a secret transmission system, frequencies called " sub-frequencies ", which in the case of speech may be 5 and 7 k.c., are modulated by the signal and caused to beat with one another to form a complex wave form comprising, in the example given, 2, 5, 7 and 12 k.c. with overlapping side bands 4 k.c. in width. The wave is then modulated on a carrier for transmission by wire or wireless. Portions between 0 and 1 k.c. and 11 and 12 k.c. may be filtered out before transmission. The Specification states that at the receiver, all the sub-frequencies and beat frequencies except one are removed before the carrier is demodulated. In the particular receiver described, and with the object of retain. ing the 5 k.c. sub-frequency and its side bands for final demodulation, the 2 and 7 k.c. subfrequencies are reinforced relatively to the 5 k.c. and subsequently removed by filters. One side band, preferably the lower, of the 5 k.c. subfrequency is removed and a local oscillator supplies 5 k.c. to enable final carrier demodulation to be effected. The Specification mentions the use of electron multipliers and the application of the invention to telegraph and television transmission.

Abstract: 1,034,815. Sheet stacking apparatus. KAYSOR BONDOR Ltd. April 24, 1963 [April 30, 1962], No. 16325/62. Heading B6H. [Also in Division B8] A machine for stacking textile articles comprises arms 6, 7 pivoted on brackets 24, 23 respectively on cross-members 25 of a table 1. At their lower ends the arms are connected by a rod 14 to the piston 15 of a pneumatic cylinder 16, and at their upper ends they carry a gripper comprising a fixed plate 8 with a movable plate 10 attached thereto, biased on to the fixed plate by gravity and held open when in the position of Fig. 1 by a stop 9, on a table 3 adjacent the table 1. In operation the leading edge of articles sewn by a sewing machine 4 on the table 3 is inserted between the plates 8 and 10. Simultaneous with the action of an automatic thread-cutter 5 air is fed to the cylinder 16 whose piston 15 imparts a pivotal movement to arms 6 and 7. At the beginning of the pivotal movement the plate 10 slides off the stop 9 and moves towards the fixed plate 8 to trap the article therebetween. Continued pivotal movement swings the plates and article over the table 1. Near the end of the swing an arm 12 on the table contacts an arm 11 on the plate 10 to release the article and allow it to fall on to the table. The piston 15 then operates a poppet valve 20 which reverses the flow of air into the cylinder 16, thus withdrawing the piston and returning the arms and plates to their original position. The cycle is then repeated to form a stack of articles on the table 1. Brackets 13 on the table may carry a rod to support the stack and facilitate its subsequent folding.
