Title: Improvements in character selection and reproduction
Inventor: DEBUS KARL-JURGEN
IPC: B41B21/04
Filed: 1966-08-18
Abstract: 1,142,979. Photographic type-composing. LINOTYPE G.m.b.H. 18 Aug., 1966 [18 Aug., 1965], No. 36939/66. Heading B6W. In a method of photographic type-composing from an illuminatable character fount one of a plurality of light deflecting members is moved into a position such as to deflect the image of a selected character, when the fount is illuminated, on to a pivoted light deflector, which deflector is moved to direct the image into the required position on a light sensitive film. In a preferred embodiment, Fig. 1, a bar shaped character carrier having 2 rows of negative characters e.g. 2, 3 in separate exchangeable mounts is mounted in front of a light source 4. Each character has its own light deflecting prism 6, 7 mounted on levers e.g. 12, 13 pivotally mounted on shaft 5 such that the prisms may be swung vertically into the optical axes of the rows of characters under the control of solenoids e.g. 10, 11. Each lever carries 2 prisms one for each row of characters. Each light beam from any moved prism in each row is directed into an optical axis common to all light beams from that row. With 2 rows there are 2 such axes, the axes of both rows being movable selectively by means of deflecting device 14 into the optical axis of the lens system 16. A character image light beam emerging from system 16 enters 90 degree pivotable prism 17 which deflects the image on to curved film strip 18 whose axis of curvature is the pivoting axis 19. Film 18 moves from spool 20 to spool 21 to effect line change and is caused to assume its curved form by rubber covered springs 22 rotating on bearings 23. Prism 17 is driven by an electric motor via arm 28, toothed segment 31 and gear train 32, 41, 44, (45, Fig. 2,) 47 and 48 which train includes solenoid operated clutch 40 and clutch plates 36 and 38. Disc 51 on spindle (46, Fig. 2) has equally spaced peripheral slots at distances corresponding to the smallest unit of count for width values of the characters. These slots provide light pulses from source 55 to photocell 56, as disc 51 rotates therebetween, in accordance with the motion of prism 17. Impulses representing a character read from punched tape pass to a counting character width value encoder and also to one of the solenoids e.g. 11 which then rocks lever 12 and brings prism 6 into the light beam axis 8 of selected character 2. The character width value passes to a counter and impulses from pulse generator 55, 56 are fed to the counter and subtracted from the width unit of the character. When the counter is empty the flash lamp 4 operates to record the character on film 18. At the end of the pivotal movement of the prism, solenoid clutch 40 is de-energized by a tape signal and prism 17 returns to its starting position under the action of a return spring.

Title: Improvements in and relating to power-assisted manual steering systems
IPC: B62D5/04
Filed: 1954-12-23
Abstract: 772,682. Electric follow-up systems. THOMPSON PRODUCTS, Inc. Dec. 23, 1954 [June 23, 1954], No. 37269/54. Class 40 (1). [Also in Groups XXXI and XXXIII] In a power-assisted manual steering system comprising a reversible electric motor 18 under the control of a manual steering member and a clutch 27, 28 for connecting the motor to the steering members and automatically operated upon starting and stopping of the motor, a lost motion connection 22 is provided between the motor and clutch to permit independent acceleration and deceleration of the motor. The invention is applicable to the steering of ships and aircraft, but as shown it is applied to a vehicle steering system comprising a steering gear 14, a steering shaft comprising portions 11. 12 interconnected by a lost motion coupling 13 and a steering wheel 10 on the portion 11. Mounted on the shaft portion 12 is a gear 17 meshing with a gear 32 carried by a shaft 30 to which are splined the clutch members 28 interleaved with the clutch members 27 splined to a housing 26. A plate carried by the housing 26 is separated from a plate 21 by balls 23 engaging ramped depressions in the plates, the plate 26 being connected to a wormwheel 20 by the lost motion connection 22 permitting up to 30 degrees relative rotation, and a worm 19 connected to the rotor of the electric motor 18 meshing with the wheel 20. One connection from the motor 18 leads to an earthed battery and the other two to contacts 40, 41 carried by the shaft portion 12, an earthed contact 42 being arranged between the contacts 40, 41 and carried by the shaft portion 11. In operation, depending on the direction of rotation of the portion 11, the lost motion in the coupling 13 is taken up and the contact 42 makes with either contact 40, 41 to energize the motor, thus causing rotation of the wheel 20, take up of the lost motion in the connection 22, and rotation of the plate 21 relative to the plate on the housing 26 thereby engaging the clutch 27, 28 to drive the portion 12 from the motor 18. Axial thrust of the clutch 27, 28 is transmitted through bearings 33, 34, 35 to a casing 16 rather than through the shaft 30 which is carried by sleeve bearings in the easing.

Abstract: 374,161. Printing-machines. LUSCHER, H., 17, Gubenerstrasse, Berlin. March 9, 1931, No. 7275. [Class 100 (ii).] Printing yarns and threads; inking-apparatus. -In a warp-thread printing-machine, a number of threads unwinding from spools 1 are attached to wooden bars 5 connected together to form an endless ;band, which passes over rollers 6a, 6b, 6c arranged in triangular formation, the drum 6b being adjustable vertically. The bars 5 are provided with teeth engaging teeth on the rollers, the roller 6c being power-driven, and each of the rollers 6a, 6c is supported by three brackets 23, the outer brackets being slidably or pivotally mounted so that they may be released from the shafts when the printed threads are to be removed, the roller 6b being slightly lowered in addition. A fixed pointer 9 indicates on a scale 8 marked on the endless band the section in printing position. Printing is effected by means of a roller 12 fixed on a shaft resting in open slots in a carriage 26, which is reciprocated on a lateral guide rail 19 by a roller carrying gears 13, 13a driven from bevel gears 14b, 14c rotated in turn and in opposite directions by a rotary mutilated bevel gear 14a. The roller 12 is enclosed in a spring- supported casing so that only a small portion of the roller is exposed for printing, and a thin ink is supplied to the casing by a pipe 11 connected to any one of a number of compartments in a container 10.

Title: Spindle for imparting false twist to yarn
IPC: D02G1/06
Filed: 1966-08-22
Abstract: 1,119,892. Twist-tubes; yarn tensioners. LEESONA CORP. 22 Aug., 1966 [22 Oct., 1965; 21 June, 1966], No. 37460/66. Heading D1D. A running, synthetic or natural fibre yarn Y is false-twisted e.g. as part of a crimping process, by passage through a rotating hollow spindle 14 and the tension in the yarn on the entry side of the spindle is automatically maintained the same as the tension on the withdrawal side thereof by use of a tube 42 which is rotated, in response to engagement by the yarn moving from the spindle, and thereby advances the yarn. The spindle 14 carries a twist head 20 in which the emerging upwardly moving yarn is passed around a guide member 26, looped around the tube 42, around guide member 28 and upwardly through bore of tube 42 to a take-up package or a feed roller therefor. Rotation of the belt-driven spindle 14 is transmitted through the frictional engagement of the loop of yarn with tube 42 to rotate the latter at a speed which is less than the spindle speed by an amount predetermined by the drag imposed by springs 48 on ball-bearings 36 the effect of which may be complemented by an adjustably spring-loaded friction brake element (58) acting on an upper cap member 40 or an adjustably positioned C-shaped permanent magnet acting upon a disc (70) of magnetic material carried on an upper extension of the tube 42, Figs. 6 and 7 (not shown). The amount of imposed drag determines the tension at which the yarn passes through the spindle. The speed differential causes the head 20 to wrap yarn around the tube 42 and feed it through the recess 43. If the yarn tension on the entry side changes then the frictional engagement of yarn Y around the tube 42 changes correspondingly and therefore the rate of yarn feed through the tube 42 changes in opposite sense to restore the correct yarn tension.

Title: Improvements in and relating to self-aligning journal bearings
Inventor: CLEFF PETER HERBERT
IPC: F16C23/04
Filed: 1960-11-01
Abstract: 925,321. Bearings. BRITISH SHIP RESEARCH ASSOCIATION. Sept. 18, 1961 [Nov. 1, 1960], No. 37518/60. Class 12 (1). A journal bearing is mounted in a supporting member so as to be self-aligning, at least one helical spring being circumferentially housed between the bearing and the support. In an embodiment the spring 4, Fig. 1, is mounted between annular tracks 12, 13 of a bearing sleeve 5 and a cap 2 of a pedestal 1; seals 7, 8 also being positioned therebetween. The track 12 is convex and the track 13 is parallel, or substantially parallel, thereto. When the tracks 12, 13 are parallel the restoring forces are at a minimum and two or more springs 4, Fig. 3, can be used so that an increase of load can be carried by the bearing without substantial increase of restoring forces. When the tracks 12, 13 are not quite parallel a variation in the radial compression of the spring occurs during misalignment of the bearing. The springs may be separated by a cage 17 which is retained in position by a dowel 19 and a screw 18.

Title: Vestigial-sideband transmission system for synchronous data signals
IPC: H04L7/027
Filed: 1975-09-12
Abstract: 1506517 Data transmission PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 12 Sept 1975 [16 Sept 1974] 37644/75 Heading H4P A transmitter 2 for use in a vestigial side band data transmission system constituted by the transmitter 2, a transmission channel 5 and a receiver 4 comprises a data signal source 1; a clock signal source 6 for synchronizing the source 1 at a data rate, for example, of 2400 bits/second; a carrier source 8; and a filtering and modulating circuit 7 arranged for generating a VSB channel signal which both at the location of its carrier frequency, e.g. 2100 Hz, and at the location of a frequency, e.g. 900 Hz which in the complete sideband is spaced from this carrier frequency by a distance, e.g. 1200 Hz, equal to one half of the clock frequency, is a double sideband modulated signal within a frequency band, having a width, e.g. 120 Hz, smaller by one order of magnitude than the frequency of the clock signal. With such an arrangement, the Specification explains, with reference to Figs. 2b to c (not shown), how the reference carrier and the reference clock signal can be recovered in the receiver 4 by the comparatively simple methods associated with DSB transmissions, even though the VSB signal is used for transmission through the channel 5 which may be a telephone line. As shown, the filtering and modulating circuit 7 includes a pre-modulating low-pass filter 16, an amplitude modulator 17 and a post-modulating filter 18, the whole being designed to produce the required vestigial sideband signal for supply to the transmission channel 5. The receiver 4 includes circuits 12, 15 to recover the reference carrier and clock signals, and suitable arrangements for these circuits are described with reference to Figs. 3 and 4 (not shown). To ensure that sufficient energy is available under all circumstances for recovery, low level pilot signals at the appropriate frequencies may also be added to the transmitted signal. Modifications of the filtering and modulating circuit 7, permitting the required VSB signal to be produced by phase-shifting techniques, are described with reference to Figs. 6 and 7 (not shown). Dibit encoding may be employed to increase the data rate.

Title: Improvements in or relating to electronic tubes having choke coils in the leads of the electrodes
IPC: H01J25/00
Filed: 1929-12-10
Abstract: 338,028. Lorenz Akt.-Ges., C. Jan. 8, 1929, [Convention date]. Vacuum tubes.-Choke coils which are arranged in the electrode leads of an electron discharge device are wound on supports fused to the glass pinch. In a short-wave generator, Fig. 1, choke coils Dr1, Dr2 are wound on glass supports T1, T2, and are connected respectively in the leads for the grid G and the anode A. High-frequency oscillations are passed on to the aerial D by leads St5, St6, between which there is connected a condenser C consisting of a small metal pipe and a pin separated by mica. The electrodes may be directly supported by the choke coils or by the supports therefor. In a modification, Fig. 2, an additional choke Dr3 is wound on a support T3 and is arranged in a filament lead. Communication may be effected with secrecy between a main station, which is equipped with a number of tubes for different wave-lengths, and one of a number of subsidiary stations provided only with tubes suitable for their respective wave-lengths. Slight difference in tubes due to manufacture may be corrected by arranging the capacity of the aerial so that a slight alteration of the wavelength may be effected. A reflecting arrangement consisting, for example, of a mirror, may be secured to a holder into which the tube is adapted to be plugged; the distance between the aerial and the reflector will then depend upon the length of the tube.
