Title: Block printing
IPC: B41F1/10
Filed: 1941-07-24
Abstract: 552,920. Printing-machines. WYKES, B., and EVANS & CO., Ltd., D. July 24, 1941, No. 9412. [Class 100 (ii)] In a multi-colour printing-machine the impressions are obtained by impact of a block charged with colour and at each impression the block is allowed to fall by gravity from the same height onto the work. As shown a block printing machine, for printing on fabric &c. supported on a table 4, is constructed of a carriage 5 which is movable longitudinally of the web by means of wheels on a rail 8, and sliding devices 9, 10, the carriage being held in registered longitudinal positions by levers engaging stops 14. The block holder 1 is mounted in a carrier 2 which is movable laterally of the web so that it may be brought over an ink or mordant charging device 3 which is formed by spreading colour or mordant over a sieve of felt or cloth stretched in a frame and placed in another frame covered at the bottom with an impermeable material such as mackintosh arranged to float in a .tub of gum. After receiving the ink the carrier 2 is moved into printing position over the fabric and is held in registered position by means of a lever 17 which is made to engage a grooved collar 18 of which there are a number corresponding to the number of lateral printing positions. The carriage 5 is movable by a cable operated by hand or motor, or it may be moved by rack-and-pinion mechanism. The printing-block holder 1 comprises two slides adjustable at right angles, and the holder is angularly adjustable in the carrier 2. The printing-block is raised prior to an inking or printing operation by means of a lever 20 connected to the carrier frame by a link 21 and pivoted to the shank 22 of the block holder 1. A locking-lever 27 fitted with a counterweight 31 engages a notch 26 in a rod 25 moving with the holder to hold the printing-block in a definite position above the table, and by releasing the lever 27 the block descends by gravity to make the impression. The descent may be assisted by a spring, and the impact of impression may be adjusted by adding weight to a cup 35a on the shank 22, or by adjusting the position of a counter-weight on the lever 20. An electromagnetic latch may replace the latch lever 27.

Title: Colour television arrangement
Inventor: SCHNEIDER HANS-DIETER
IPC: H04N5/18
Filed: 1970-01-12
Abstract: 1299838 Colour television ROBERT BOSCH FERNSEHANLAGEN GmbH 12 Jan 1970 [11 Jan 1969] 9529/72 Divided out of 1289082 Heading H4F The respective black values of the three colour signals produced by a colour television camera 40 are compared by arranging for the camera tubes' electron beams to be interrupted by horizontal provisional blanking pulses H (Fig. 2c) and blanking pulses V<SP>1</SP> (Fig. 2f) which comprise vertical provisional blanking pulses V (Fig. 2b) to which have been added in pulse former 41 additional pulses (Fig. 2e) situated in the line forward traces following the vertical blanking component of the standard blanking pulses A (Fig. 2a) with which the video signals are subsequently blanked at the camera output. The electron beams of the camera tubes are thus blanked (interrupted) by the pulse mixture shown in Fig. 2g, and each of the resulting output video signals R, G and B are as shown in Fig. 2h, where 42 indicates the standard blanking value and 43 indicates the provisional blanking value (which correspond to the black value) established by the blanking of the electron beam by the additional pulses. The provisional blanking values (indicated at 43 in Fig. 2h) of the three colour signals are then simultaneously displayed on an oscilloscope 47 for comparison with each other. Clamping circuits 44, 45 and 46 controlled by pulses V and H may be included if desired. Device 51 may be merely a distribution device or it may include means for blanking the lines indicated at 43 in Fig. 2h, such means being effective only for colour signal outputs 48, 49 and 50 and not for the outputs which are connected to the oscilloscope. The above arrangement may be used in flying spot colour film scanners, in which case it is more advantageous to blank the input stage of each colour signal amplifier instead of the flying spot light beam.

Title: Improvements in or relating to cathode ray tubes
IPC: H01J31/58
Filed: 1947-04-10
Abstract: 650,689. Cathode-ray tubes. RADIO CORPORATION OF AMERICA. April 10, 1947, No. 9606. Convention date, April 12, 1946. [Class 39 (i)] A cathode-ray storage tube comprises within the envelope an electron gun, a conductive target having a plurality of mutually insulated elemental areas, an electron multiplier between gun and target, electrostatic scanning means and an electron-permeable screen adjacent and in front of the target which controls secondary electrons bombarded from the target to which successive signal potentials are applied. The grid 4 and first and second anodes 5, 9 are of tubular construction mounted together by means of four mica strips 11 and through which the electrodes are welded to metal strips 13, 14, 15. To the end of the second anode is welded a metal disc 17 separated by mica discs and spacing rods from a further metal disc 20 sandwiched between mica discs 21, 22. Holes in these discs accommodate and insulate metal rods 37, 38 which are attached to and support the horizontal and vertical deflecting plates. A shield disc 16 surrounds the gun assembly and is flanged at 45a and welded to a cup-shaped gun mount 45b. A focusing electrode 47 is positioned at the gun end of the wall coating 46 and multiplier stages 48-53 and collector 54 are positioned over the shield tube 16 accommodating the gun electrodes. The target 2 is convex and of aluminium with an oxidized coating and a screen 61 stretched over the surface. A focusing ring 62 is adjacent the target. In the operation of the tube, the high velocity beam from the electron gun liberates secondary electrons from the target surface which tends to assume the potential of the screen 61. In a coherent pulse radar system echoes from stationary and moving objects are received on the signal plate and control the secondary emission therefrom, but only the echoes from the moving objects vary sufficiently in amplitude and change in phase to produce modulation of the electron beam returning to the multiplier. In order to compensate for the slow variation of amplitude in successive pulses from a fixed object due to material breadth of radar antenna, two tubes may be run in cascade. Specification 634,639 is referred to.

Title: Improvements relating to control arrangements for d.c. electric motors
Inventor: MCBREEN JAMES PATRICK
IPC: H02P7/26
Filed: 1953-04-09
Abstract: 730,115. Rectifying. METROPOLITANVICKERS ELECTRICAL CO., Ltd. March 31, 1954 [April 9, 1953], No. 9679/53. Class 38 (2). [Also in Group XXXVII] Relates to control arrangements for D.C. motors fed from multi-phase rectifiers of the grid-controlled type in which the direct output voltage is controlled by peaking transformers connected to the control grids which regulate the firing of the main anodes. As shown, a phase shifter feeds the peaking transformers 1A, 1B, 1C, which in turn supply firing pulses to the control grids of the rectifier. A fixed negative grid bias is afforded through resistors 3, the positive terminal of the bias source 2 being connected to the cathode of the rectifier. The primary circuits of the peaking transformers each comprise reactors 6A, 6B, 6C, and, normally, contacts 5A, 5B, 5C are closed so that regulating resistors 4A, 4B, 4C are shortcircuited. When, however, it is desired to effect inching or creeping of the motor, the contacts 5A, 5B, 5C are opened so that the regulating resistors are inserted. When resistance is so added, the power factor of the supply to the peaking transformers is increased and the pulsed output from the peaking transformers is advanced in phase to an adjustable degree dependent upon the value of the resistance regulators. Several rectifiers may operate in parallel to supply a motor load, the regulating resistor short-circuiting contacts being ganged for simultaneous operation. Each the resistors 4A, 4B, 4C may be replaced by two resistors in series and contacts provided to shortcircuit either or both resistors whereby either inching control or creep control may be provided, in addition to normal operation. Thus for inching; both resistors are employed whilst for creep speed only one resistor is used, Fig. 2 (not shown). Alternatively, capacitors may be substituted for the regulating resistors and adjustment effected by having a number of small capacitor units and connecting a number of such units in parallel.

Title: Improvements in and relating to the production of gamma-butyrolactone
Filed: 1946-03-29
Abstract: Gamma-butyrolactone is obtained by oxidizing tetrahydrofuran, or a 2-alkyl substituted tetrahydrofuran wherein the alkyl radical contains not more than six carbon atoms, at a temperature below its boiling point by means of nitrogen tetroxide.  The conditions of the reaction are preferably anhydrous and at atmospheric pressure.  A temperature of not less than 20 DEG  C. is used, and the molar ratio of nitrogen tetroxide to tetrahydrofuran is not more than 1.5:1.  The nitrogen tetroxide is mixed with air or oxygen advantageously, and is bubbled through the reaction mixture or produced in situ, e.g. from nitrogen trioxide or nitric oxide and oxygen or air.  Specified solvents are ether, dionan.  The process may be continuous.  In examples: (1) 92 gm. of nitrogen tetroxide is entrained in a stream of oxygen and passed into 72 gm. tetrahydrofuran at 40 DEG  to 50 DEG C. and at the end of the reaction oxygen is blown through the liquid product to remove the nitrogen trioxide to obtain gammabutyrolactone; (2) 43.4 gm. tetrahydrosyloan in ether solution is oxidized by a stream of nitrogen tetroxide and oxygen at 30 DEG  to 40 DEG  C., the reaction product is stripped of N2O4 and distilled to obtain gamma-butyrolactone, with gamma-aceto-propanol as a by-product.

Title: A new or improved machine for wrapping cylindrical canister or carton bodies
IPC: B31B15/00
Filed: 1940-06-05
Abstract: 541,698. Packing. LEVER BROS. & UNILEVER, Ltd. (Kuiken, B.). June 5, 1940, No. 9866. [Class 94(1)] A machine for wrapping cylindrical canister or carton bodies in tubular wrappers of paper, cellulosic film, or like sheet material comprises means for pressing a sheet of the material around the body by a pair of pressers which are moved in opposite directions around the body until they come together at or near the edges of the sheet. The cartons 1, Fig. 2, are stored in a rack 2 from which they are carried one at a time to the wrapping station 3 by means of a pair of centres which engage in the open ends. During. this movement, a carton meets a sheet 4 of the wrapping material which is cut off by shears 6 from a continuous strip or is drawn from a stack. The sheet is held in contact with the carton by a support 7, and when the carton reaches the wrapping-position 3 it is engaged by two pressers 8, 9 which press the sheet against the lower side of the carton. The pressers 8, 9 then move in opposite directions around and in contact with the carton as shown in positions I-IV of Fig. 1, progressively pressing the wrapper against the carton surface. The pressers finally come to position III where they are close together and where one edge of the sheet overlaps the other edge 10. The pressers 9 then move forward slightly, and the presser 8 moves backwards, as shown in position IV, to press the edge 11, to which adhesive has been applied on to the edge 10 to secure the wrapper. The rack 2, Fig. 3, is inclined and is provided with a stop composed of a pair of fixed curved arms 13 and a hinged plate 14 that is urged upwards by springs. The lowermost carton is removed by a downward pull that deflects the plate 14. Removal of a carton is effected by centres 15, Fig. 7, which are carried by bellcrank levers 23 pivoted to a crosshead 16 that reciprocates vertically. The movement of the centres is such that they are moved apart, then raised and closed on the ends of the carton, and then moved downwards again carrying the carton with them. The support 7 is carried by rods 30 that slide in the crosshead 16, the movement of the centres and the support being affected by cam-operated levers. The sheet of wrapping material is drawn from a roll 5 by grippers 63, Fig. 2, which reciprocates horizontally and grip the leading edge of the material. The pressers 8, 9 consist of steel blades carried by members 35 which are pivoted on stub axles, and are moved around the carton by gear segments 37 rocked by cams. A line of adhesive is applied to the strip of material by a trough 99 from which a strip of felt projects, the trough being supplied with adhesive from a reservoir 93. The trough is raised and lowered by cams, being lifted when the grippers 63 draw the material forwards. When the material has been drawn forward, it is cut by the shears 6 to separate a sheet which is wrapped around the carton. The wrapped carton is ejected into a shoot 12 by a bell crank 52 which is rocked by a downwards movement of the support 7.

Title: Systems for the transmission of angular motion
IPC: G08C19/48
Filed: 1923-04-11
Abstract: 199,357. British Thomson-Houston Co., Ltd., (Assignees of Hildebrand, L. E.). June 16, 1922, [Convention date]. Order apparatus.-In a system for transmitting angular motion, the output of the transmitter is amplified for the operation of any desired number of receivers. The armature winding of the transmitter 10, Fig. 1, comprises three windings 14, 15, 16 connected respectively to the grid circuits of three vacuum tube amplifiers 17, 18, 19. The output circuits of the tubes are connected to the primaries 34 of transformers 31, 32, 33, the secondaries of which are connected to the receiving circuit mains 37, 38, 39. Receivers 40, 41, 42, similar to the transmitter 10, are connected to the mains 37, 38, 39. The field windings of the transmitter and receivers are supplied from singlephase mains 13. Movement of the rotor of the transmitter 10 varies the voltages induced in the armature windings and these voltages are transmitted through the tubes 17, 18, 19 to the mains 37, 38, 39. An unbalanced voltage condition is thus caused between the receivers and their supply mains, and equalizing currents are set up in the armature winding of the receivers to exert torques on their rotors and so reproduce any movement imparted to the transmitter. In the modification shown in Fig. 2, differences in the voltages of the transmitter and receivers are applied to the grid circuits of the vacuum tubes. The primary windings 53 of the pairs of transformers 50, 51, 52 are connected across the armature windings 14, 15, 16 and the primaries 54 are connected to the receiving circuit mains which are supplied by transformers 31, 32, 33. The secondaries 58, 59 of each pair of transformers are connected in series and in opposition in the grid circuit of the tubes, so that when the receivers are in angular agreement with the, transmitter no voltages are impressed on the grid circuits. In a further modifi. cation, the primaries 54, Fig. 2, are connected through conductors 55, 56, 57, Fig. 3, to an auxiliary transmitter 60 which is directly connected to a receiver 40.
