Title: Time fuse for projectiles
IPC: F42C9/04
Filed: 1920-09-25
Abstract: 151,632. Neufeldt & Kuhnke. April 20, 1918, [Convention date]. Escapements.-A vibrating reed carried by a fixed support is used to control the escapement of a clockwork fuse for timing the explosion of projectiles. In the form shown, a clockwork mechanism 3 is driven by a weighted arm 10 when this is subjected to centrifugal force during the flight of the projectile. The drive is transmitted from this arm to the clockwork through a coiled spring 7, and the escapement is controlled by a reed 4 which is set vibrating by the shock to which the projectile is subjected when discharged. Specification 28708/02, [Class 9, Ammunition &c.], is referred to.

Title: Pattern scanning system
IPC: G06V30/162
Filed: 1968-06-10
Abstract: 1,219,334. Pattern recognition. INTERNATIONAL BUSINESS MACHINES CORP. 10 June, 1968 [20 June, 1967], No. 27410/68. Heading G4R. A pattern scanning system scans a pattern and digitizes the resulting video signal using a threshold device, the variable threshold level of which is generated by a generator including means for selecting the highest at any instant of a plurality of thresholds. A character scanner feeds a delay line 30 via a low-pass filter and automatic gain control circuit (not. shown), the middle of five taps on the delay line feeding a voltage discriminator 32 in which the waveform is digitized against a threshold from an analogue OR gate 38 before feeding a shift register 41 via a flip-flop 33 for recognition at 40. Line width is detected at 42 (as in Specification 1,158,939 which is referred to) from the shift register contents to lower (whiten) the threshold for thin-lined characters (see below). The OR gate 38 passes the largest of its three inputs, one of which is a constant voltage T min and the others are derived as follows. The centre delay line tap voltage is followed by a contrast detector 46 (which comprises an integrator and acts as a low-pass filter) as long as it exceeds T min (as detected at 44), to produce a contrast signal which is amplified 48 to accentuate the contrast then shifted down by adding a negative value at 50. Manual switch 54 ensures that in the case of typewritten documents the value is fixed K1 while in the case of machine printed documents the value is K1 plus a line width factor from 42 reduced at 56. The output of adder 50 is a contrast (average blackness) threshold applied to OR gate 38. The delay line taps feed an OR gate 64 to obtain the peak signal in a region bracketing the current scan point, the peak being amplified 66 to accentuate variations, then shifted down by adding a negative factor at 68, a manual switch 72 ensuring that the value is a constant K2 for machine printing and the sum of a constant K3 and the reduced line width factor from 56 for typewriter printing. The output of adder 68 is a peak threshold. The average of the delay line tap outputs is determined at 74 then shifted up by adding a constant K4 at 76 to obtain an average level threshold for a region bracketing the current scan point. A capacitor store 90, providing the third input to OR gate 38, receives the peak and average level thresholds and follows the former if a flip-flop 92 is reset and follows the higher is the flip-flop 92 is set. Flip-flop 92 is set when the output of discriminator 32 goes from black (character) to white (background) and is reset on retrace (i.e. another scan through the pattern) and when black has existed at the output of discriminator 32 for a predetermined time as determined by an integrator feeding a thresholder in " black timer " 96.

Abstract: 924,353. Machines with static rectifiers in place of commutators. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 5, 1960 [Aug. 11, 1959], No. 27446/59. Class 38 (2). [Also in Group XL (c)] An electronic switching circuit (see Group XL (c)) is used as a commutator for an electric motor. Two gas-filled switching devices SD1, SD2 are cross-coupled by capacitor C such that either one or the other is conducting to pass current through either winding a or a<SP>1</SP> depending on the position of the windings relative to the poles. For starting and slow speed running, when the E.M.F. across the coils is inadequate for charging the capacitor, the necessary charging may be achieved by the inclusion of resistors R1, R2 connected to a source of potential. Rectifiers Rf3, Rf4 may be provided to prevent current being driven back into this source by the voltage generated in the windings. The switching devices used may be thyratrons, cold cathode tubes, grid-controlled mercury arc rectifiers, semi-conductor controlled diodes or hard valves (Fig. 2, not shown).

Abstract: 228,633. Audianne, P., and Bachalard, G. Nov. 8, 1923. Catalytic apparatus; sulphur trioxide, catalytic production of.-In the manufacture of sulphuric anhydride by the contact process, grains of an inert porous substance impregnated with a vanadium salt are arranged in layers, the size of the grains being uniform in each layer but decreasing in successive layers traversed bv the gas mixture, the smaller grains containing a larger proportion of vanadic anhydride. The grains may vary from 2 to 5 mm. in diameter, and contain 50-55 kgr. of vanadic anhydride per cubic metre of gross volume, Oxides of metals such as iron, tungsten, or molybdenum may be added to the catalyst, say in the proportion of 2-3 per cent of the weight of the vanadic acid. In order to initiate the reaction, the gases may be passed first through a thin layer of platinum catalyst; they may also be slightly moistened. In the apparatus shown, the gases pass downwards through layers 8-12 of vanadium catalyst, separated by spaces in which are baffles 14 deflecting the gases against the wall of the chamber, which has cooling flanges 16 and is surrounded by an outer casing through which flows the untreated gas from a pipe 3.

Abstract: 339,971. Triggs, W. W., (Multicolor Films, Inc.). Sept. 17, 1929. Coating webs.-Film material, particularly kinematograph film, is coloured by running it along the surface of the colouring liquid on which the lower face of the film is pressed by guides adapted also to prevent the liquid from contacting with the upper face of the film. In apparatus for carrying out the method, the liquid is contained in a tank 12 which is slightly wider than the film strip. The latter is passed over sprockets 25 and 27 between which it is guided through a channel 23 formed by the horizontal flanges 21 on angles 18 mounted on the side walls 17 of the tank. The guiding channels 23 are dipped downwardly at their centres so that the film is there caused to press on the surface of the liquid. The horizontal flanges 21 cover the film sprocket holes and the channels 23 are only slightly wider than the thickness of the film so that surface tension prevents the liquid being pressed through on to the upper face of the film. The remaining spaces in the channels 23 may be filled with a fluid such as mercury of large surface tension or the edges of the film may be treated with a water repellant substance.

Title: Improvements relating to television transmitting apparatus
Inventor: LUBSZYNSKI HANS GERHARD
IPC: H04N5/217
Filed: 1949-11-04
Abstract: 686,313. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Nov. 6, 1950 [Nov. 4, 1949], No. 28243/49. Class 40 (iii). The invention relates to television pick-up tubes arranged to operate with cathode potential stabilization and is concerned with the elimination of black streaks which sometimes occur in pictures reconstituted from signals generated by such tubes. The invention is based on a realization of the fact that, when the target electrode is illuminated very intensely, the photo-electron current does not remain constant but decreases to an equilibrium value, due to a failure of the positive electrodes of the tube to saturate the emission, within a time which is less than a frame period and may be only a few line periods. Accordingly, when the scanning beam restores the charged mosaic elements of the target to cathode potential, the photo-electron current increases and remains at the saturation level until the elements have once again charged to the potential where the positive electrodes fail to effect saturation. Such variations in the photo-electron current produce corresponding variations across the output load and impose components varying in the black direction on the normal signals. In accordance with the invention, the pick-up tube is connected in a circuit arranged as shown in Fig. 1, in which, in addition to the normal output taken from load 13 and applied through amplifier 14, a second output signal representative of the photo-electron current is derived from mesh electrode 11 (ion trap) and applied through amplifier 16 and valve stage 17 to amplifier 14 where it is combined with the normal signal with such amplitude and phase as to balance out the undesired variations. The photo-electron current which is collected in part by electrode 11 includes high-frequency components introduced by the portion of the scanning current not utilized in stabilizing the mosaic elements, and the time constant of circuit 18, 19 in conjunction with the cathode output resistance of valve 17 is selected to eliminate such high frequency components whilst allowing the relatively lowfrequency components due to the variations in photo-electron current to pass. Load 15 connected to electrode 11 may alternatively be connected to either electrode 4 or 10, although, in these cases, the portion of the photo-electron current collected by the respective electrode is dependent upon the position of the intensely bright parts of the image. The invention is applicable to pick-up tubes employing an image section. The Provisional. Specification, Fig. 1 (not shown), describes a modified filter connected in the cathode circuit of valve 17.
