Title: Relaxation oscillation circuit for interlaced scanning in television
IPC: H03K4/86
Filed: 1935-11-21
Abstract: 454,471. Television. RADIOAKT.- GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. Nov. 21, 1935, No. 32284. Convention date, Nov. 23, 1934. [Classes 40 (iii) and 40 (v)] The initiation of the discharge in a relaxation oscillator for a cathode-ray tube in a receiver using interlaced scanning is controlled by impulses from the transmitter, and the termination of the discharge is determined by voltages generated at the receiver. The discharge is terminated by giving the potential of the cathode 5 of the discharge tube 3 a positive value sufficient to quench the discharge. For this purpose, the cathode is earthed through a condenser 14 in parallel with a resistance 15. The time constant of the condenser is much greater than the time of the discharge. Alternatively, simultaneously with the triggering of the discharge tube, a valve is operated to cause the charging of a condenser through a resistance with a properly adjusted time constant, and on complete charging, after a fixed period of time, the discharge of the tube 3 is interrupted.

Title: Cycle change speed gear
IPC: B62M9/16
Filed: 1949-12-19
Abstract: 669,693. Variable-speed gearing. CAMPAGNOLO, T. Dec. 19, 1949 [July 19, 1949], No. 32537/49. Class 80 (ii). [Also in Group XXXI] In a shifting-chain type of cycle change-speed gear, in which the wheel spindle is declutched from the supporting forks when effecting a change of gear as described in Specification 415,683, [Group XXXI], the two operations are adapted to be carried out by means of a single control member. This control member comprises a rod 1 which is turned to effect a gear' change and during the first part of its movement it operates a declutching member traversing the hub by means of an eccentric on the rod within a cap member 10. During the latter part of the turning movement of the rod a spring-pressed sleeve member 5 with an axial projection 5' moves axially to engage a recess 2<SP>1</SP> in a member 2 fixed on the rod 1 and is then turned therewith to impart a swinging movement to an arm 6<SP>1</SP> carrying a fork 6 engaging over the chain. The chain is thereby shifted onto the desired sprocket and on return movement of the control member, with a cessation of pedalling, the sleeve 5 disengages from the member 2 owing to the reaction of the arm against the stationary chain and the wheel spindle is re-clutched to its forks. This declutching allows the wheel spindle 18, guided by teeth thereon engaging rack teeth 19 in the forks, to assume a position maintaining the chain tension, but means to provide a slight slackening of the chain are also provided comprising a cam 7 on the rod 1 which acts on a pawl 8, 8<SP>11</SP> to engage and rotate slightly a toothed wheel 11 on the end of the spindle just before the re-clutching of the spindle takes place. The amount of chain slackening is adjustable by varying the stroke of pawl 8 by means of a nut 17 on the end of rod 1.

Title: Improvements in or relating to sheet feeding mechanisms
IPC: B65H7/12
Filed: 1949-12-20
Abstract: 688,629. Feeding sheets. BACKHOUSE, H. T. Dec. 20, 1950 [Dec. 20, 1949], No. 32569/49. Class 100(i) In sheet-feeding apparatus of the kind wherein a tower sheet is being registered on a feed board while an upper or preceding sheet is being transferred from the board to a printing or other machine, a scraper device 1, having one arm 3 adapted to move with a scraping action against the underside of the sheet being transferred to a position in which it lies above and close to the board 2 and overlying the sheet about to be transferred, has embodied in the scraper arm a suction nozzle 4, and a further suction nozzle 10 is provided in or on the feed-board, these two nozzles forming in known manner a means for detecting the presence of two superposed sheets between the nozzles. The scraper 1 is actuated as described in either of Specifications 657,616 or 657,618 and is secured to a rockable shaft 13. The suction orifice 4 communicates with a port 8 in a side face of the scraper which, in the position shown, is in communication with the cylinder 12 through a passage 20 in a wall 17 extending from the cylinder. The orifice 10 in the feed-board 2 also communicates with the cylinder 12 through a passage 11 in the board. A piston 14 in the cylinder is lightly spring- urged to the left so that a piston rod 15 cannot extend into the path of a radial sensing arm 24 on a collar 23 secured to a rockable shaft 22. The cylinder 12 is connected to a source of suction by a pipe 26. In operation, when the arm 3 is in the position shown and only one sheet is between the arm and the board 2, then air is admitted through one or the other of the orifices 4, 10, whereby a vacuum cannot be created in the cylinder 12 to the right of the piston and the latter will remain spring- urged to the left. If, however, there are two superposed sheets beneath the arm 3, both suction orifices 4, 10, are sealed, a vacuum is created to the right of the piston which is then drawn along the cylinder 12, the piston rod IS is extended into the path of the oscillating arm 24 to stop the oscillation of the shaft 22, and this, through known mechanism, effects stoppage of the sheet-feeding apparatus and operates a warning device. The scraper device 1, 3, a section of the feedboard embodying the orifice 10, the cylinder 12, and sensing arm 24 may be constructed as a single unit to be affixed to a feed or lay-board.

Filed: 1923-12-31
Abstract: 224,752. Jackson, W. J. Mellersh-, (Flintkote Co.). Dec. 31, 1923. Impregnating fabrics in long lengths.-Felt is impregnated with molten asphaltic material under pressure. A web of felt is passed round a roller 20, a movable take-up roll 24, a roll 22, round a roll 26 at the bottom of a tank 10 containing asphalt, and then over rolls 23, 25, 21 similar to the first three. The travel through the asphalt is intermittent and during the pause when the impregnation takes place the slack is taken up by the roll 24. Increase of pressure is effected by the admission of compressed air to a stand-pipe 100 by a valve 106 operated by the chain mechanism which drives the roll 24 along guides 53. An open tank 14 surmounts the tank 10 and communicates with it by an opening 13 fitted with sliding gate members 16, 17 which are closed just prior to the increase in pressure in the tank 10. The members 16, 17 are actuated by levers operated by the chains 59, 60. Specification 224,751 is referred to.

Abstract: 1,134,006. Selective signalling. SCM CORP. 26 Oct., 1965 [26 Oct., 1964], No. 33177/68. Divided out of 1,134,003. Heading G4H. In a data processing system including a typewriter and a field control responsive to the position of the typewriter carriage for conditioning the change of state of at least one control device, the state of said conditional control device is actually changed only in response to operation of one of the typewriter alphanumeric keys. In a data processing system described more fully in the parent Specification and comprising two paper tape readers the paper tapes of which contain information in intermixed positions for the control of a typewriter and/or of a paper tape punch, provision is made when entering data manually by way of typewriter keys for turning off the punch and/or turning on one or other reader automatically according to a predetermined programme. For this purpose, a punched paper tape 1301 (Fig. 5) is secured to a metal plate 1302 of the typewriter carriage and co-operates with spring contacts 1303 a-h for generating control signals corresponding to the sensing of holes 1304 in the tape. These signals, together with other control signals, arm pulse gates 1305, 1306 for generating punch off and reader 1 on signals on lines 1308, 1309 respectively. Similar means for controlling reader 2 would be provided. The trigger pulses for gates 1305, 1306 are derived from transfer pulses TF on line 1112 through a pulse gate 1311 whenever a key is depressed as indicated by a signal on encoder out line 1501. The output of gate 1311 switches on a monostable multivibrator 1307-which controls a four layer diode oscillator 1312 for producing a series of high frequency pulses over a 17 m.s. period to ensure correct operation of the system however rapidly the keys are depressed. The field control operation described is inhibited (at AND gate 1313) whenever a reader is on or the carriage is running in a reverse direction. The keyboard is locked whilst a reader is on and to ensure fast locking of the keys after the key causing the reader on signal to be generated has been depressed, quick acting locking means 1315, 1316, 1319, 1320, 1322- 1326 are provided in addition to other means not shown.
