Title: Improvements in or relating to television apparatus
Inventor: FAUDELL CHARLES LESLIE
IPC: H04N5/213
Filed: 1948-07-16
Abstract: 652,066. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 16, 1948, No. 19103. Drawings to Specification. [Class 40 (iii)] [Also in Group XL (c)] In apparatus in which operations are effected under the control of regularly-occurring synchronizing pulses, interference due to extraneous noise pulses is reduced by integrating the incoming synchronizing and noise pulses and applying them to a limiter which produces an output when the integrated pulse attains a predetermined amplitude, this output signal is then delayed so that the operation is effected in coincidence with the next succeeding unintegrated synchronizing pulse. The apparatus is described in its application to a television system in which noise pulses occurring during the line synchronizing period are prevented from causing errors in synchronization. To maintain synchronization in the event of a failure in, for example, the delay circuit apparatus the unintegrated synchronizing pulses may be applied after a very short further delay to the line scanning generator so that on failure of the delayed integrated pulse, the scanning generator will be synchronized after a short time interval.

Title: Production of shrink-resistant wool
Inventor: GOLDBERG ALAN AUGUST
IPC: D06M15/592
Filed: 1964-05-07
Abstract: Wool and wool-containing materials are shrink-proofed by wetting-out a continuous length thereof with an aqueous liquor containing (a) a wetting agent, e.g. an anionic or nonionic wetting agent such as a condensation product of trimethylnonylphenol with 6 moles of ethylene oxide, (b) a shrink-resistance-imparting halogen-free oxidising agent for wool, e.g. permonosulphuric acid or potassium permanganate, and (c) at least one water-soluble acid having a dissociation constant K greater than 1 x 10-3 at 25 DEG C or a water-soluble salt thereof, e.g. sulphuric acid, sodium chloride, sodium sulphate, sodium bisulphate or ammonium sulphate, immediately after wetting-out passing the material through the nip between a pair of rollers so to to ensure that the material is uniformly impregnated with a controlled amount of the liquor while maintaining the controlled amount of liquor in contact with the material until at least a desired amount of the oxidising agent has reacted with the wool with which it is in contact, and feeding metered quantities of aqueous solutions of the oxidising agent, wetting agent and water-soluble acid or salt to maintain a substantially constant composition, the quantities being correlated with the rate of pickup of liquor by the materials so that (a) the volume of liquor remains substantially constant and (b) complete renewal of the liquor takes place in 1 - 15 minutes.  The wool may be in the form of yarns, tops or woven or knitted fabrics.  The material may be wetted with the aqueous liquor either by immersion for 1 - 2 seconds or by spraying, and the pickup of the aqueous liquor at the nip may be 50 - 250%. The treated material may subsequently be washed with water, passed through an aqueous solution of a reducing agent, e.g. sodium sulphate or acidified sodium bisulphite, again washed with water and finally dried.

Title: Drive systems
IPC: B60L11/18
Filed: 1973-04-19
Abstract: 1380015 Vehicle transmissions LINDE AG 19 April 1973 [26 April 1972] 19153/73 Heading B7H [Also in Division H2] In a drive system particularly for a fork lift truck a shunt wound electric motor 1 is arranged to drive the vehicle wheels through an infinitely variable hydrostatic transmission, there being a control lever coupled to means for varying the field excitation of the motor and to means for adjusting the transmission so that the field excitation is first decreased to increase the motor speed before the transmission is adjusted. As shown in Fig. 1, the D.C. motor 1 drives variable hydraulic pumps 2, 3 for propelling the truck and actuating the hoist mechanism 14, 15, 16 respectively, and a constant delivery pump 4 for other drive systems on the truck. The pump 2 drives hydraulic motors 7, 8 for each wheel 10 through gearing 9. The pump 4 delivers fluid through block 17 to tilt cylinders 18 which actuate the hoist frame, or a hydrostatic steering mechanism through device 19, 20, or to connections 21 for other hydraulic auxiliaries. In a preferred circuit for varying the field excitation, Fig. 2, a line 29 containing the field winding 23 of the electric motor 22, 23 has a variable resistor 30 operationally linked to the throttle pedal 24 such that at low speeds of travel resistor 30 is disconnected whilst at higher speeds resistance of resistor 30 increases so that when power required for acceleration corresponds to the full power of the electric motor, resistor 40 is fully in circuit and the electric motor runs at maximum speed. Any further increase in travel speed is then achieved exclusively through the throttle pedal on the hydrostatic transmission. Another circuit Fig. 3, is arranged such that as pedal 24 is moved to increase travel speed resistor 30 is adjusted to decrease conductance of transistor 32. The current in a fixed resistor 31 increases with voltage across winding 23 being reduced until ultimately transistor 32 ceases to conduct altogether and the entire field current has to flow across resistor 31. Even smaller losses can be achieved by using a field winding (36), (43), Fig. 4 (not shown), of split design. In a modification of the circuit of Fig. 2, Fig. 5 (not shown), a changeover switch (37) is operationally linked with a control. lever (38) by means of which a valve (not shown) in line 13, Fig. 1, is operated, this valve operating the hydraulic hoist 14, 15, 16. In a further modification, Fig. 7, a 6/2-way valve 41 is connected through coupling device 42 to the steering mechanism so that at large steering deflections the particular one of the two hydraulic motors 7, 8 which is on the inside of the curve is short-circuited.

Title: Improvements in measuring and weighing devices for filling machines
IPC: G01G13/00
Filed: 1928-07-03
Abstract: 293,460. Hesser Maschinen-Fabrik- Akt.-Ges., F. July 7, 1927, [Convention date]. Packeting materials in receptacles.-In a package-filling or similar machine provided with weighing and measuring devices and having a plurality of supply hoppers, each having a conveyer worm and feed-gate, the worm and feedgate are controlled by a feeler that is resiliently impelled towards or away from the filling position of the package synchronously with the automatic supply of packages thereto. A package P receives an initial charge from a hopper 97, Fig. 2, and is then moved on to a weigh-pan 155, Fig. 3, suspended from a weigh-beam 140 where it receives a final charge from a hopper 97<1>. The hoppers are provided with worm conveyers 106, 1061 rotated through chains and bevel gears from a counter shaft 43 driven by a continuously-rotating shaft 9. Feed-gates 33, 33<1> are normally maintained in closed position by spring-pressed slide bars 26, 26<1> that are controlled by cams 39, 39' on the shaft 9. Spring-pressed feelers 1, 1<1> are impelled towards the package in filling position at the commencement of each operation. In the event of there being no-package beneath the hopper 97 the feeler 1 moves to position c, thus allowing the end 17 of a lever 15 to de-clutch the driving pulley 40 from the shaft 9 to prevent rotation of the worm 106. At the same time a latch 21 is dropped into engagement with a stop 25 on the slide bar 26 to lock the feed-gate in closed position. In the event of the feeler being held in position b by engagement with a package, the feed-gate is allowed to open and material is fed into the package by the worm 106, the extent of rotation of which for each revoluion of the shaft 9 is controlled by a handle 86. The amount of material fed into the package from the hopper 97<1> is controlled by the weigh-beam 140, for which purpose a contact 149 carried by the weights-pan support co-operates with fixed mercury cups 150 to make and break a control circuit for an electromagnetic clutch through which the counter shaft 43 is connected to the worm 106<1>. If a package is on the weigh-pan 155, a feeler 1<1> closes contacts 124, 126 in circuit with a magnet 134 to raise a latch 21<1> and allow the feed-gate to open. Rotation of the worm 106<1> while the feed-gate is closed, is prevented by the inclusion of contacts 133 in the clutch circuit, which contacts are closed by a roller 131 on the slide bar 26<1> as the feed-gate opens.

Abstract: 130,988. Miller, W. J. Aug. 11, 1917, [Convention date]. Moulding under pressure.- In a press of the type in which the moulds E are carried on rotating arms 16, a cylindrical block 113 is mounted directly below the pressing plunger and is surrounded bv a sleeve 114 having a bevelled upper edge T. As the mould E arrives beneath the plunger, it rides over the edge T, and is thus raised slightly, being supported during the pressing operation by the block 113, the arms 16 thus being relieved of strain. The sleeve 114 is raised to the position shown by fluid pressure acting on a piston 119 as soon as the mould E is in position above the block 113. Accurate centring is thus insured.

Title: Improvements in wire tying machines
Inventor: COPLAND WILLIAM ORANMORE
IPC: B65B27/06
Filed: 1955-07-04
Abstract: 816,675. Bundling machines. GERRARD INDUSTRIES Ltd., and RYLANDS BROS. Ltd. Aug. 30, 1956 [July 4, 1955], No. 19298/55. Class 94(1). In a machine for applying wire ties to coils of wire or rod and securing their ends by twisting on the inside of the coils, the tying wire is fed from a supply on a drum 7 through a guide 18 and between feeding and tensioning rollers 5 carried by a work head which is mounted on a rod 16 supported by a counterweighted lever 12 and guided for vertical movement within an aperture in a rotatable table (not shown) on which the coil C to be tied is supported. One roller 5 is spring-loaded and the other is driven through gearing and an extensible splined shaft 4 by a reversible electric motor 2. The wire is fed from the rollers 5 through a guide 20 to pass freely between the first of a pair of toothed grippers 21, 22 and the central post 23 of a rotary block 24 in which the grippers are mounted, and is then led under the coil C and back around the coil for insertion between the second gripper 22 and the post 23. The grippers are movable axially in a tapering slideway 25 and are actuated by a spring 26 under the control of a manually-operated lever (not shown). The block 24 is rotatable through gearing and an extensible splined shaft 6 by an electric motor 3 to effect twisting of the wires and is formed with a knife edge 28 which severs the wire from the supply at the commencement of this operation. The machine is controlled by a pedal-operated lever 8 coupled to a link 10 having a pin and slot connection with the lever 12. The initial movement of the pedal actuates a microswitch 17 to energise the motor 2 and cause wire to be fed beneath the coil C, the work head being in the lowered position. The head is then raised by a further depression of the pedal and locked in the raised position by a latch (not shown) controlled by the gripperoperating lever and the pedal is then released to stop the wire feeding operation. After the wire has been trained around the coil and its free end clamped by the gripper 22, a switch is depressed to start the motor 2 in the reverse direction so that the wire is drawn back by the rollers 5 and tensioned about the coil. This operation pulls the coil towards the work head so that it depresses a lever 29 to cause operation of two micro-switches, one of which stops the motor 2 and the other srats the motor 3 to cause rotation of the block 24 to sever the wire from the supply and twist the ends of the tie. The shaft 6 carries a worm 19 which drives adjustable mechanism operating a switch which stops the motor 3 after a predetermined number of twists have been made. The gripperoperating lever is then actuated to release the grippers and latch to free the coil and allow descent of the work head. The table is then rotated to position the coil for the application of a second tie spaced circumferentially from the first.

Title: Improvements in or relating to cathode ray storage tubes
Inventor: ALLARD LAWRENCE SIDNEY
IPC: H01J31/12
Filed: 1967-04-27
Abstract: 1,150,060. Cathode ray storage tubes. M-O VALVE CO. Ltd. 11 April, 1968 [27 April, 1967], No. 19456/67. Heading H1D. A cathode-ray storage tube including a writing gun 17 and at least one flood gun 9 has a storage screen comprising a conductive layer 5 covered by a bombardment induced conductivity layer 7 coated with a storage layer 8 which is preferably a fluorescent material and which is semi-continuous, i.e. the layer appears continuous but adjacent particles are not in good electrical contact with each other. The conductive layer may be of tin oxide; the layer 7 may be of cadmium sulphide, magnesium fluoride, zinc sulphide or aluminium oxide; and the phosphor 8 may be manganese-activated zinc silicate. The wall coatings 10-12 collimate the flood electrons and may be maintained at voltages of 180, 100 and 50 v. respectively relative to the earthed cathodes of guns 9, the cathode of gun 17 being at -10 kv.; the layer 5 is connected to a potential which is variable, e.g. between 50 and 350 v. In operation, the layer 5 is first operated at about 350 v., rapidly lowered to 50 v., and then slowly raised to 300 v. which is above the first cross-over value of the secondary emission ratio for the storage layer 8. This layer is thus stabilized at earth potential, but at points where the layer is struck by the writing beam the induced conductivity of layer 7 raises the potential of the layer 8 above its cross-over point so that it is stabilized at this point and luminesces due to bombardment by the flood electrons. The charge image can be erased by raising the potential of the conductive layer 5 to 350 v., thereby causing the layer 8 to charge uniformly.

Abstract: 1,173,486. Gelatine compositions; polysaccharides. EASTMAN KODAK CO. 27 April, 1967 [2 May, 1966], No. 19460/67. Headings C3H and C3U. [Also in Division G2] Gelatin containing compositions, such as photographic silver halide emulsions, are hardened by incorporating poly(dialdehyde dextrose) made by oxidation of a synthetic polydextrose obtained by polycondensation of dextrose in dimethyl sulphone or tetramethylene sulphone in the presence of a Lewis acid. The poly (dialdehyde dextrose) also acts as an antifoggant and is incorporated by adding as an aqueous solution to aqueous gelatin solution. The gelatin which is hardened includes gelatin derivatives and mixtures of gelatin with ethyl acrylate or butyl acrylate copolymers with acrylic acid. When used in silver halide emulsions these may contain the usual additives and may be used for example in diffusion transfer processes. The use of poly (dialdehyde dextrose) as a hardener in silver halide materials which are developed in the presence of colour couplers reduces the formation of stain. A synthetic polydextrose is obtained by heating dextrose and 85% phosphoric acid in dimethyl sulphone or tetramethylene sulphone solution under partial vacuum while distilling off a sulphone-water azeotrope. The polymer was filtered off and reprecipitated from aqueous solution with acetone. Poly (dialdehyde dextrose) is made by oxidizing the above polydextrose with periodic acid at about room temperature and isolated by pouring into acetone, filtering and washing with methanol.
