Title: Improvements in or relating to means for reproducing film pictures on a screen of electric lights
IPC: G09F13/28
Filed: 1934-06-29
Abstract: 438,219. Television. ROSENBERG, H., 14, Tauentzienstrasse, Berlin. June 29, 1934, No. 19310. Convention date, June 29, 1933. Addition to 411,835. Drawings to Specification. [Class 40 (iii)] The invention relates to an arrangement for reproducing pictures carried on a film on a bank of incandescent lamps which are fed by alternating current selectively controlled by electronic discharge devices associated with light-responsive devices exposed to light rays passing through the film, as described in the parent Specification. According to the present invention the frequencies of the alternating current and of the change of the projected film pictures are related in such a manner that the current frequency is equal to or an integral multiple of the frequency of the change of the film pictures, and the driving mechanism operates so that each interval between the display of consecutive picture frames ends during a negative halfcycle of the alternating current. In the negative arrangement, i.e. a black area on the film causing the corresponding lamp to be illuminated-the interval is arranged to begin in the same negative half-cycle, and, in the positive arrangement, at any time after the beginning of the preceding positive halfcycle. The film is driven through an adjustable coupling from a motor fed by the alternating current supply of the lamps.

Abstract: 1,150,501. Analysis of a segmented stream. CESKOSLOVENSKIA AKADEMIE VED. 3 May, 1966 [5 May, 1965], No. 19457/66. Heading B1X [Also in Division G1] For example amino acid-containing element from chromatography column 3 mixed with ninhydrin reagent from line 6 and segmented with gas at 7 is carried out on successive sections of the liquid which are separated from one another by gas bubbles 16, and a photoelectric system is provided to determine the actual position of a section to be analysed so as to adjust the relative positions of the analysis apparatus and the section. A series of segments of reaction mixture, separated by gas bubbles, reaches the reaction capillary 13, which is immersed in a high-temperature bath 21. The reaction takes place and the segments travel to tube 14 for evaluation of the concentration gradient by analysis of the individual sections at regular instants over a period of time. In order that the analysis apparatus views a segment of liquid rather than a bubble a photoelectric system detects bubbles as they flow past a light source, and controls the position of the analysis apparatus along the capillary tube, in accordance with the timing of the bubbles. The analysis apparatus is arranged to view the middle portion of a segment, avoiding the parts close to the subbles, which carry particles of solid, liquid or gas which interfere with accurate analysis. Instead of moving the analysis apparatus to maintain this constant positional relationship, the latter may remain fixed, and the pressure in the chamber 20 is regulated to control the speed of bubbles, under the control of the photoelectric system. In Fig. 2 (not shown), in which the position of the analysis apparatus is changed, light from a source (22) passes through capillary tube 14 and is detected by a photocell (25). Bubbles passing along the tube are detected and the resultant signals transmitted to a device (27). If there are any fluctuations in timing and size of the bubbles device (27) energises a servo motor (29) to cause movement of the analysis apparatus so that it always, views the middle of a liquid section. In Fig. 3 (not shown), an elongated light source e.g. a fluorescent tube (32) is used and a rotating polyangular prism reflects light from a bubble moving along the tube 14 onto the detector (25). The movement of bubbles along the tube is followed by changing the speed of rotation of the prism (33) to retain the image of the meniscus on the detector and the position of the analysis apparatus adjusted in accordance with this rotation.

Abstract: 982,044. Heat exchange elements. BORG-WARNER CORPORATION. May 30, 1961, No. 19565/61. Heading F4S, A turbulizer element intended for insertion in the fluid passage of a heat exchanger, comprises a corrugated metal strip with the corrugations arranged in successive groups 12 disposed side-by-side along the direction of the longitudinal axis of the strip (indicated by the double arrow in Fig. 1), each group comprising corrugations 14, 24 at different angles to a transverse axis 16 of the strip, thereby providing a plurality of tortuous fluid flow paths through the element. In the form shown the corrugations of the groups 12 are arranged in sections 11, 11a. The corrugations in groups 11 extend along lines 15 at one angle to the axis 16 and the corrugations in groups 11a extend along lines 17 at an opposite angle to the axis 16. A primary sinuous flow path is thus provided for fluid flowing over the turbulizer element in the genera] direction 16. A secondary sinuous flow path of greater frequency than the primary path is provided (as denoted by the arrow in Fig. 2) by forming the corrugations 24 (i.e. those separating adjacent corrugations 14) at a slight angle to the corrugations 14. The turbulator may be placed in the heat exchanger so that the fluid flow in a general direction along the corrugations (as shown), or in a general direction at right-angles thereto (Figs. 5, 6, not shown). The turbulator may be used in an annular passage, or in a generally " flat " passage of the heat exchanger.

Abstract: 515,816. Board games. STOREY, W. H. July 2, 1938, No. 19679. [Class 132 (ii)] In a board game "men" are-moved from one side of the board to the opposite side according to instruction given by a pack of cards. The board, a is divided into squares, and men are placed on alternate "start" squares adjacent the edge of the board a, each group of squares b<2> ... b<4> having a different colour. There are five "men" of each colour, and four suits to the pack of cards. The first suit, Fig. 2, com- 'prises eighteen cards having an arrow e and one of the numerals 1 ... 5 and 7, there being three of each, indicating the number of squares a man may be moved in the forward direction. The second suit also comprises eighteen cards, three of which, as shown in Fig. 4, have a three headed arrow f and the numeral 1 to indicate that one man may be moved one square forwardly or sideways. The remaining cards, as shown in Fig. 5, have a double arrow system' g, and, in'threes, one of the numerals 2 ... 5 and 7 to indicate the number of squares a man may be moved either sideways or sideways and forwardly. The third suit, as shown in Fig. 3, comprises four cards bearing two arrows h and the numeral 8 to indicate that one man may be moved forward eight squares, or two men an aggregate of eight squares. The fourth suit, as 'shown in Fig. 6, also comprises four cards, bearing arrows i, j. The arrow i bears a numeral 6 and indicates that a man may be moved forwardly six squares, while the numeral 9 on the arrow j indicates that a man may, alternately, be moved sideways and forwardly a total of nine squares. The object of the game is to move all five men across the board to occupy the corresponding "start" squares on the opposite side. If a man is moved on to a square occupied by an opponent, the latter is moved back to one of his start squares unless it is in one of four safety zones d, in which case the original ." man " cannot be moved. If a "man " has to move back to the start squares and the latter are all occupied, it is transferred to a penalty base c in the corner of the board, of which there is one for each colour, and is not released to a vacant starting square until a forfeit is paid.

Abstract: 1,181,490. Taking up slack in cables; masted lift trucks. CLARK EQUIPMENT CO. 26 April, 1968 [12 June, 1967], No. 20059/68. Headings B8B and B8H. An apparatus for receiving a pair of flexible fluid conduits 76, 86 extending between a movable and a stationary section of a lift truck telescopic mast comprises a beam 108 movable relative and parallel to the mast sections and having a sheave assembly 94, 96 at each end around each of which, one of the conduits is looped. The conduits extend in opposite directions from a plate 138 attached to the movable mast section, around the sheave assemblies 94, 96 which are spring-biased outwardly from the beam 108, and are then coupled to a plate 134 mounted on the stationary mast section. Contraction in either conduit due to fluid pressurization therein is absorbed by compression of the spring associated with the appropriate sheave assembly, and flexible electrical conductors 140, 148 coextending with and clipped to the conduits merely become slack when the conduit contracts. In the embodiment of Figs. 9, 10 (not shown), the sheave assemblies at the ends of the beam are not spring-loaded but the conductors are spring-biased to take up slack and remove tension in the conductors as the beam moves, due to contraction of the conduits. The embodiment of Fig. 11 (not shown), is similar to the previous embodiment but both conductors are coupled together by a spring- loaded plate which is linearly movable to tension both conductors, or pivotally movable to take up slack in one and pay out the other. The conduits supply fluid to be used as a power source to a valve on a carrier vertically movable on the upper section of the mast, and the valve is controlled by solenoids supplied with power via the said conductors. The carrier is movable by chains extending between the carrier and the cylinder of a mast operating fluid ram and passing over sprockets on the upper piston of the ram. Both a two- and a three-section mast are described.

Abstract: 477,056. Vehicle spring suspensions. GENERAL MOTORS CORPORATION. July 21, 1936, No. 20163. Convention date, Aug. 22, 1935. [Classes 108 (ii) and 108 (iii)] In vehicle suspensions in which each wheel is independently supported at the end of a lever arm which preferably oscillates parallelly to the longitudinal axis of the vehicle about a horizontal transverse axis the suspension comprises a torsion spring and an auxiliary spring adapted to reduce the effective rate of the torsion spring adjacent to its normal load position. The longitudinal wheel-carrying arm 9 is mounted on a pivot member 7, which is carried by a bracket 5 pivoted on a king pin 3 on the end of the axle beam 1, the king pin being inclined to give the wheel 13 the requisite caster and the arm 9 being inclined as shown. The pivot member 7 is secured to a torsion bar spring 17, Fig. 5, the other end of which is secured at 18 to an encircling torsion tube 19 anchored at its other end to the bracket 5 so that the torsion rod 17 and torsion tube 19 act in series. Secured to the pivot member 7 is a lever 23 of a toggle lever system the other member comprising the auxiliary spring 25 in compression so that as the lever arm 9 deflects the spring 25 assists the torsion spring, but the assistance becomes less as the deflection increases, thereby in effect increasing the rate or hardness of the torsion spring. The bracket member 5 is hollow and contains the toggle system the lever 23 of which is provided with two lugs 33, 34, Fig. 4, adapted to bear upon the pistons 35, 36 of an hydraulic damper. At the end of the damper casing 39, two bosses 44, 45 are provided each having a bore and counterbore 46 within which is arranged a spring pressed valve 50, Fig. 6. Upward deflection of the arm 23 forces the piston 36, Fig. 4, inwards and forces the valve 50 off its seat permitting the pressure fluid to pass into the cylinder 37 through the restricted aperture 46<1>, and causing the piston 35 to follow the lug 33. Downward deflection of the arm 23 is resisted in similar manner, the valve 50 in the boss 45 being actuated. In place of a coiled spring 25, a Bellwille washer spring may be used.

Abstract: 1,242,367. Solid state memory devices. FORD MOTOR CO. Ltd. 28 April, 1970 [15 May, 1969], No. 20230/70. Heading H1K. A solid state memory device comprises a conductive base on which is provided an oxide layer thick enough, e.g. 100-1000 , to prevent electrons from tunnelling therethrough. The thick oxide layer carries a plurality of discrete metal droplets, e.g. 10<SP>9</SP> in an area 3 mm. x 2 mm, having their surfaces remote from the thick oxide layer covered with thin coatings, e.g. of oxide, nitride or sulphide, through which tunnelling can occur and which in turn are covered by a common metal conductive film. When a small direct voltage is impressed across the device the capacitor formed across the thick oxide layer charges up as electrons tunnel through the thin coatings on the metal droplets. When the device is operated at 4À2 K. the charge across each small capacitor comprising a droplet, its coating and the overlying metal film increases with voltage in discrete steps corresponding to the tunnelling of single electrons through the coating. After relaxation of all these small capacitors by the passage of time, optionally enhanced by the shining of light on to the droplet coatings through the overlying metal film, read-out from the device consists of measuring its A.C. capacitance as a function of applied direct voltage. It is found that the value of A.C. capacitance dips sharply for values of applied direct voltage equal to the previously impressed voltage, and if two voltages have been impressed alternately before relaxation, dips in the A.C. capacitance value occur for both voltages. The conductive base may be a 2000  thick film of Al or Ta, the thick oxide layer being formed by gaseous or anodic oxidation thereof and the metal droplets comprising vacuum evaporated Pb, Sn, Bi or In and having an average diameter of about 100 . The upper metal film may also be formed by evaporation.
