IPC: A63F13/10
Filed: 2003-05-21
Abstract: A problem of the known mobile devices having motion sensors, where translational and/or rotational motion of the device is used to control aspects of the game, is that rotation of the device also rotates the image shown on the display. This is due to the fact that the image is bound and fitted to the physical display. Hence, when the device is rotated in relation to the eye line of a user, the image also rotates. For example, rotation of 360180 degrees results in the image having the wrong side up. This is avoided by detecting an amount of rotational movement of the mobile device in a rotation direction, when rotational movement takes place on a plane parallel to the display plane. Then the view to the game on the display is rotated in the opposite rotation direction and by the same amount. Therefore the view is maintained stationary to the eye line of the user.

Title: Ferric complexes of hydrogenated dextrans for - parenteral and/or enteral treatment of iron-deficiency
IPC: C08B37/02
Filed: 1968-07-15
Granted: 1971-01-11
Abstract: Ferric complexes of hydrogenated dextrans for parenteral and/or enteral treatment of iron-deficiency in human and/or veterinary medicine. Prepared by mixing precipitated, washed and filtered iron hydroxide, in the moist state, with dry hydrogenated dextran and, optionally, citric acid or its alkali metal salts to give a homogeneous mass, basifying this with NaOH soln., heating the stirred mixture until the end-product is water-soluble, cooling the resulting soln., filtering, and treating the filtrate with an ion-exchanger to remove excess NaOH. Teh hydrogenated dextran used pref. has a reducing power (determined by the Samogyi method) of 0.02-3.0 glucose gramme equvs./100 g. Advantages are that the product has low toxicity and is cheap and easy to make (colloidal ferric hydroxide is not needed, dialysis and electrodialysis are not employed, and materials are used in high concns. so that the working volume of the apparatus used is reduced). The optional use of citric acid or its alkali metal salts reduces the heating time required to make the complex water-soluble, improves the physical properties of the soln. obtained and minimise the fall in pH when the product is treated with ion-exchanger to remove excess NaOH.

A process for making a tufted carpet wherein a hot melt adhesive composition is applied to the bottom surface of a tufted structure 10 by contacting the said surface with a hot melt applicator roll 12 and thereafter a secondary scrim 22 is placed in contact with said adhesive coated surface, comprises: (a) applying pressure to said tufted structure whilst it is in contact with the applicator roll 12 by at least one hold-down roll 16, 18 positioned above the applicator roll and in contact with the top surface of the tufted structure, the clearance between the or each hold-down roll and the applicator roll being predetermined to provide the desired combination of scrim bond and fuzz-resisting properties in the tufted carpet to be prepared; (b) placing the scrim 22 in contact with said adhesive-coated surface quickly after the structure leaves the applicator roll and (c) supporting the assembly, e.g. by support 28 until the adhesive has cooled below its hot tack temperature. In the preferred embodiment, the carpet structure is passed through the nip of rolls 24 and 26 before cooling and through the nip of a second pair of rolls 30 and 32 prior to passing it to a conventional tenter frame and cooler. The tufted structure may comprise polypropylene or acrylic fibres and a primary backing of woven jute fibres; alternatively, it may comprise nylon fibres and a primary backing of polypropylene fibres. The secondary scrim may be of jute. Specified adhesive compositions which may contain wax, e.g. petroleum wax, are based on polymers, e.g. ethylene-vinyl acetate copolymers, copolymers of ethylene with an acrylate or methacrylate and polyethylene.

Abstract: 1,232,641. Protective systems. COMPAGNIE DES COMPTEURS. 28 May, 1968 [1 June, 1967; 20 March, 1968], No. 25518/68. Heading H2K. A distance protective arrangement for a three-phase transmission line has for each phase devices 10, 12, 13 deriving signals proportional to the voltage to earth, the line current and the derivative of the line current, and switching or counting means 21, 21a, 21b controlled by a timer 6 to periodically apply the signals to a computer 7 which functions to add two products, dependent on the inductive and resistive voltage drops, for each phase, the resulting straight line characteristics for the three phases passing through a common point on an impedance diagram, the position of the point being representative of the distance to a fault. The computer 7 is programmed to repeatedly perform the calculations necessary to determine both interphase and phase/earth faults within a protected section, the underlying theory being given in the Specification. In the arrangement disclosed, the devices providing the signals are a capacitive voltage divider 10, a shunt 12 and an air-cored transformer 13. The transmission of the signals from the components 12, 13 at high potential to the equipment at earth potential may be effected by radio, or as shown by light transmission. Thus the signals are applied to converters 11, 11a, 11b which provide output signals with frequencies dependent on the magnitude of the respective input signal, the output signals from converters 11a, 11b being applied to light emitting diodes in transmitters 14a, 14b connected by glass-fibre light guides to photo-diodes in receivers 15a, 15b. The signals from the converter 11 and receivers 15a, 15b are frequency multiplied at 16, 16a, 16b and mixed at 20, 20a, 20b with frequency multiplied signals from a reference generator 17, the filtered outputs from the mixers 20, 20a, 20b being repeatedly counted by counters 21, 21a, 21b under the control of the clock timer 6 for application to the computer 7. Various modifications and circuits for the components are described.

Abstract: 1,232,919. Drafting device. N. SCHLUMBERGER & CIE. 17 Nov., 1969 [28 Nov., 1968], No. 56110/69. Headings DID and D1N. A drafting device comprises two fields 8, 9 of fibre control elements positioned between the feed and drafting rolls 1, 2, 3, 4, 5 and movable in the direction of motion of the fibres. One of these fields is formed by bars 18 carrying flexible strips 13 which are folded back on themselves to form a loop which presses against the fibrous material. The other fibre control field may be an apron or another set of bars carrying flexible lips. The bars in each of the two fields may be opposite or offset from each other. The bars carrying the strips may be arranged inside an endless belt which has a run between the drafting and feed rolls. The bars carrying the strips may be moved by an endless belt, a notched belt, chain or by screws. The bars in the two fields may move at the same or different speeds. The bars may be carried on a support which is movable perpendiculary to the plane of the strips. The drafting system can comprise porcupine rollers, gill boxes, intersecting combs or drafting aprons.
