Title: Improvements in and relating to fountain pens
IPC: B43K7/10
Filed: 1939-07-28
Abstract: 531,654. Fountain pens. LAFOREST, J. July 28, 1939, No. 21972. Convention date, July 28, 1938. [Class 146 (iii)] A fountain pen of the ball type in which ink is supplied to the tracing ball 6 by one or more balls 7. 8 which have an axial displacement limited by a stop is constructed with a stop formed of two or more wires 11, 12, which are preferably twisted together, the ends of the wires being spread by the feeding-ball 8 upon pressure being applied to the tracing-ball. The spreading of the wires is limited by the walls of a screw member 13 connected to a member A which screws into the pen reservoir. To the member B is secured a flared stamped metal tube C in which the balls 6, 7, 8 are arranged, this tube having an oval or similar cross-section at the position adjacent the ball 8 thus providing a passage for.the ink to flow past the ball 8. The wires 11, 12 are formed at the top end into a ring 10, Fig. 5, which bears on a shoulder in the member A. The space between the wires 11, 12 forms a capillary conduit conveying ink to the balls and acting also as a vent for the reservoir. Between the members A, B is a compensation chamber E formed of a number of compartments separated by baffles or washers 13 formed with apertures 14 connecting the compartments, or containing a helical spring of low pitch which confines ink, which overflows into the chamber E through an aperture 17 when the pressure is high to a helical path. The ink returns to the compartment B when the pressure is reduced and air can enter the aperture 17 via the chamber E and an air inlet aperture 15. The flow of ink can be regulated by relative motion of the members A, B, between which members is a washer 18 which acts as a brake to retain them in the adjusted position.

Title: Process for colouring polyethylene terephthalate textile materials
Inventor: MICHIE ARTHUR GEORGE HALL
IPC: D06P3/54
Filed: 1950-09-07
Abstract: Textile materials comprising polyethylene terephthalate are coloured by padding or printing a dyestuff on to the materials, drying, and subsequently heating to an elevated temperature under tension to prevent or control shrinkage.  Suitable dyestuffs are the dispersed water-insoluble dyestuffs, water-soluble acetate dyes, vat dyes, methine dyes and aminoanthraquinone derivatives, as well as azoic components, and many such dyestuffs are specified.  The heating of the material after the application of the dyestuff may take place on a heated drum provided with pins as described in Specification 700,100 or on a heated stenter machine, or in the case of yarn, by passing the yarn over a driven capstan, through a heated tube and then over a second driven capstan. Temperatures of 150 DEG  to 255 DEG C are specified.  In Examples, (1) a fabric is printed with a paste containing the dyestuff p  p-aminoacetanilide --> p-cresol, sodium m-nitrobenzene sulphonate, an emulsion of sulphonated sperm oil and pine oil, and crystal gum thickening, dried, and passed around a heated drum at 230 DEG C provided with pins round the edges to hold the fabric; (2) a fabric is padded with a suspension containing Durindone Printing Red BS, ammonium polymethacrylate and sulphonated oleic acid, dried, and heated on a drum as in (1) to 240 DEG C; (3) a fabric is padded with a suspension containing 3-nitro-4-aminotoluene --> acetoacetanilide, ammonium polymethacrylate and sulphonated oleic acid, dried and heated as in (1) to 230 DEG C; and (4) a fabric is padded with a suspension containing 1-hydroxy-4-aminoanthraquinone, ammonium polymethacrylate and sulphonated oleic acid, dried and heated as in (1).

Title: Improvements in or relating to flight simulators
IPC: G09B9/14
Filed: 1966-05-18
Abstract: 1,146,213. Aircraft flight simulators. CURTISS-WRIGHT CORP. 18 May, 1966 [21 May, 1965], No. 22707/66. Heading B7W. An aircraft flight simulator comprises a base B on which is mounted horizontally disposed hydraulic actuators 7, 8, 9 each having an associated thrust transmitting linkage 4, 5 or 6 also mounted on the base B and adapted to transmit the movements of the actuators to the platform F of the pilot's cockpit C. Each linkage 4, 5 or 6 comprises a bell-crank lever pivoted to base supports 14 and having one crank end connected to the piston rod 12 of its associated actuator, the other crank end being connected by a vertical strut 1, 2 or 3 and a universal joint 15, 16 or 17 to the cockpit platform F. To improve the lateral rigidity of the platform a generally A-shaped frame 20 is pivoted at 22 to the base B and is connected by a universal joint 21 to the platform F. Simulation of aircraft roll, bank, or pitch &c. is achieved by individual or simultaneous operation of the actuators in response to electrical signals supplied to the solenoids 28 of the valves 106 controlling the supply and exhaust of hydraulic pressure fluid to the actuators. Each control valve 10b is operated according to the magnitude and sense of the signal received by its solenoid. The signal received by a particular solenoid is the algebraic sum of three signals: the first being supplied by a flight computer; the second being supplied by a rotary potentiometer 25, 26 or 27 responsive to the angular position of the associated bellcrank; and the third from an adjustable " trim " potentiometer. The arrangement is such that the signal from the rotary potentiometer increases as its bell crank moves away from a neutral position thereby reducing the effect of the computer signal to cause the valve controlled thereby to move towards its closed position.

Abstract: 1344103 Moulding multilayered food T HAYASHI 19 April 1971 [24 Feb 1970] 22263/7l Heading B5A Multilayered food articles comprising layers of fat, custard or jelly or paste, intermediate layers of kneaded cereal dough, e.g. sweet rolls or Danish pastries, are moulded by successively delivering, e.g. from the encasing machine of Specifications 1,218,256 and 1,222,856, spherical blanks 2 (comprising butter or paste encased in the dough) down a shoot 9 on to an endless conveyer 11 wherein they are compressed, on to a preceding compressed blank and against a support 10, by a press plate 3 which is intermittently reciprocated in synchronism with the delivery of the blanks, preferably by a crank drive taken from the encasing machine. In the Fig. 3 embodiment, a continuous length of multilayered material is produced by continuous movement of of the belt 10, preferably by an amount between successive blank deliveries which is half or less of the length of each compressed blank. The continuous length is preferably conveyed by a first further endless belt for further compression between an upper roll 17 and a lower belt driving roll 14, and may be cut into short lengths by providing the upper roll 17 with a pair of cutting blades parallel to its axis each of a configuration tangential to the roller on its downstream side, and radially thereto on its upstream side. The food material is preferably further conveyed by a second further endless belt which initially follows an initially upwardly inclined path, whereon the material is retained by an endless moving chain belt, and then follows a horizontal path. The endless conveyers are preferably driven at progressively increasing speeds, preferably independently variable. In the Fig. 4 embodiment, the belt 11 moves intermittently between a successive member of reciprocations of the press plate 3 producing individual multilayered articles of circular crosssection. Where individual articles are produced, these may be rolled into a bar shape between the second further endless belt and the endless chain conveyer which is maintained stationary. In the particular example, relating to the Fig. 4 embodiment, a continuous multilayered dough and butter article was obtained of 200 mm. width and 6À6 mm. thickness, and which comprised 90 layers of butter.

Title: Improvements relating to impact rolling or tamping machines for the compaction of loose materials, such as road surfaces
IPC: E02D3/026
Filed: 1953-08-13
Abstract: 744,701. Sand rollers. BERRANGE, A. R. Aug. 13, 1953 [Aug. 14, 1952], No. 22376/53. Class 6 (1). An impact roller comprises a ground-engaging roller having a plurality of salient corners a<SP>1</SP> projecting from the roller and curved tamping surfaces a<SP>2</SP> joined to the salient corners on one end by a re-entrant portion a<SP>3</SP> and curving tangentially into the salient corners on the other end and a mounting on which the roller is rotatably mounted. As shown, the roller rotates on an axle fixed to circular plates f pivoted on pins h which pass through journals j. Rollers g engage saddles k mounted on leaf springs l when the frame is moved in a horizontal direction, the movement being resisted by the springs thus overcoming drawbar jerk at low speeds. As shown in Fig. 3, the roller is mounted on a support frame o connected by parallel links f to the main frame m. Leaf springs l anchored to the frame m are provided with rollers n which engage with tracks k and resist movement of the frame o in a vertical direction. In a modification the roller shaft is connected to a pair of crank arms to which are pivotally attached wheels which run in vertical guides and are provided with springs which resist movement in a vertical direction. The roller frame is provided with a universal joint 81 for attachment to a tractor. The roller may be attached to a two-wheeled tractor. For transport purposes a set of wheels may be fitted to the roller frame in such a way that they could be lowered to the ground by means of screws or hydraulic jacks or alternatively filling pieces may be provided for fitting into the roller to bring the overall periphery of the roller to a plain cylindrical shape. Alternatively the roller may be basically of cylindrical shape and provided with pieces externally shaped to give the desired profile and removably fitted to the roller.

Title: Improvements in or relating to automatic couplings for model railway vehicles
IPC: A63H19/18
Filed: 1956-07-19
Abstract: 815,616. Model railway vehicle couplings. PRITCHARD, S. C. July 19, 1957 [July 19, 1956], No. 22395/56. Class 132(3) [Also in Group XXXII] A coupling for model railway vehicles which swings sideways for coupling and uncoupling comprises a coupling hook provided with a projection which interengages with the hook of a similar coupling to limit vertical movement between the couplings and thus to avoid uncoupling due to the couplings either being out of adjustment or to irregularities in the track causing one coupling to ride above the other. As, shown, a coupling arm 12 which is intended to swivel only sideways is provided with a hook 17 having a vertically extending portion 17a and a rearwardly extending projection 17b. The projection on one of a pair of interengaged couplings limits relative vertical movement in one direction and the projection on the other coupling limits relative vertical movement in the other direction. The arm 12 also has a depending uncoupling striker member 21. The projection may alternatively be provided at the top of the vertically extending portion of the hook instead of at the bottom, the projection then serving as means for retaining other couplings, e.g. a chain. The coupling arm may comprise a leaf spring mounted on the vehicle so that the hook can swing sideways. Specification 605,283 is referred to.

Abstract: 727,900. Semi-conductor devices. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 25, 1951 [Sept. 29, 1950], No. 22405/51. Class 37. A P-N junction unit in a semi-conductor, as described in Specification 728,129, is completed by the addition of electrodes. As shown (Fig. 3), the semi-conductor 10, preferably neutral, is sandwiched between an acceptor impurity element 11 and a donor 12, and submitted to a heating cycle whereby a P-N junction area 15 is produced by diffusion of the impurity elements into the semi-conductor. Electrodes 16, 17 are secured by fusion during the heating cycle, electrode 17 as shown being a metallic plug, or secured by other means, e.g. soldering. The impurity elements may be added separately and the heating cycle duplicated. Alternatively the semi-conductor may be initially P- or N- type, and only one impurity element applied and diffused. The external surface of the semiconductor may be etched as at 18 in the region of the impurity elements after completion of the diffusion process. In a modification (Fig. 6) both sides of the semi-conductor are completely covered by the impurity elements 11, 12 enabling the use of heavy electrodes 20, 21, which may be water-cooled by internal conduits 22. The P-N junction may be constructed with three electrodes (Fig. 8) to form a transistor. Specification 700,231, [Group II], also is referred to.

Title: Improvements in sensitive materials for colour photography
IPC: G03C7/26
Filed: 1956-07-20
Abstract: 804,662. Colour photographic materials. KODAK, Ltd. July 20, 1956 [July 26, 1955], No. 22496/56. Class 98(2) A support bears at least two superposed differentially sensitive silver halide emulsion layers each containing a different non- diffusing colour coupler and each containing a nucleating agent for catalyzing the reduction of or for precipitating dissolved silver salts, and also containing a non- diffusing non-colour forming reducing agent. The emulsion layers may be of the usual red/cyan, green/magenta and blue/ yellow sensitivity/coupler sequence starting from the support and may all be fast, in which case a yellow filter is included beneath the upper layer, or the lower layers may be slow, with omission of the yellow filter. The material may be exposed, black and white developed, acidstopped, washed, then directly colour developed with a developer including a silver halide solvent, stopped, washed, bleached, washed, fixed and washed; thus effecting reversal without re-exposure before the colour development. An example describes production and processing of such material in full detail, using colloidal silver as nucleating agent and 2 : 5-di-sec octyl hydroquinone as the reducing agent referred to above. Numerous similar agents of both types, and also colour formers for the layers are quoted. A somewhat similar procedure in which the non-diffusing. non-colour forming reducing agent is not used, but requiring the presence of additional, barrier, layers containing nuclei between the emulsion layers to check diffusion of silver salts dissolved during colour development is described. Specifications 545,448, 547,064, 562,205, 680,488 and 804,661 are referred to.

Filed: 1959-07-02
Abstract: 871,658. Type-bar-making machines. MERGENTHALER LINOTYPE CO. July 2, 1959 [Sept. 29, 1958], No. 22714/59. Class 100(3) Assembling matrices. The dashpot 31, for resisting the action of the spring urging the line transfer carriage of a typographical line-casting machine into delivery position, comprises a plunger 35 in a cylinder 33 having an aperture 42 and a larger aperture 41, the latter allowing air to escape freely. When the plunger is raised by the spring, a partial vacuum created below the plunger produces a constant retarding force, adjustable by a cap 43 over a port 39. When the carriage is halted in a waiting position owing to the non-completion of the previous casting cycle, the plunger is just below the aperture 41, and on further movement, air is therefore admitted more rapidly, and the carriage moves more quickly. The constant force and lower speed before stopping prevents separation of the lefthand finger from the line. The construction of the carriage with its fingers, and the cam for stopping it in a waiting position, are substantially the same as in Specification 454,722.
