Patent GB-1302986-A (GB)
IPC: G06F3/044
Filed: 1971-04-19
Abstract: 1302986 Determining co-ordinates digitally INFONET NV 19 April 1971 [27 Feb 1970] 22464/71 Heading G4H The digitized co-ordinate position of a stylus on, say, a graph, borne on a grid of cross-wires is determined as a number of cross-wires plus the distance from a cross-wire to the point of stylus tact, so providing positional accuracy when the stylus is between two wires. The x and y coordinates are determined separately in turn. The co-ordinate wires 1-10 ... each receive from register 16, driven by clock-pulse generator 14 and divider 15, five pulses, the first pulse of each series being 90 degrees behind the first pulse of the series to the preceding conductor. A stylus P capacitively receives the sum of two such pulse trains when positioned between two wires. The signal from the stylus after amplification (20) stops by its leading edge the gate 17 from feeding clock pulses to counter 18 whose total then expresses the coarse position of the stylus, which is the lower numbered of the two wires between which the stylus is found. The regi - ster goes on to pulse the remaining cross-wires of the co-ordinate to complete its cycle. Meanwhile the relative amplitudes of a pair of peaks in the stylus signal, indicating the distance of the stylus from the lower numbered cross-wire, is digitized, 28 (Fig. 7, not shown), and added to the coarse measurement in the display 19. The other co-ordinate is now determined in a similar way. Any number of pulses in the stylus signal other than five is detected by a unit 22 to erase the display.

Title: Improvements in or relating to flying machines
IPC: B64C39/00
Filed: 1931-08-10
Abstract: 378,641. Aircraft with combined rotary and reciprocating wing systems; linkages. KORWIN, G. J. DE, La Madeleine, Cannes, France. Aug. 10, 1931, No. 22603. Convention date, Aug. 21, 1930. [Classes 4 and 114.] In a flying ma. chine comprising wing surfaces freely rotatable about a vertical axis and in which each wing is free to swing about a horizontal axis, the wing surfaces are reciprocated along their vertical axis, the resulting reactions from the air on the wings causing all the wing surfaces to revolve in the same direction about the vertical axis. Fig. 10 shows a flying machine having two sets of four-bladed rotors, with blades of aerofoil section, which are oppositely reciprocated on a vertical column E by means of an engine G carried in a body F. The blades which are arranged to be flexible transversely and stiff longitudinally are carried on tubes B, Fig. 3, socketed in rings C freely rotatable on sliders D<1>, D2. The engine drives a three-armed crank J through reduction gearing I. Connected to the crank J are rods L<1>, L<2> coupled to the slider D<2> . and a rod K coupled to the slider D<1>. Stops are provided to limit swinging movements of the wings, these comprising rollers M, Fig. 3, mounted on the wing roots and arranged to contact with cam rings N mounted on the sliders by means of three spaced links O which may be collectively or independently adjusted in length by the pilot through flexible, pneumatic, hydraulic, electrical or other transmission, to alter the position of the ring N and hence to govern the movements of the wing. A second stop roller M<1> may be connected to the roller M by a link m and arranged to contact with ring N on upward movement of the wing. Lateral or longitudinal control may be effected by non-uniform adjustment of the link O. A propelling engine R driving an airscrew Y may be fitted in the body F and be mounted in a swinging trunnion bearing S. Handles T on the engine permit of swinging it in any desired direction within fixed limits to turn or tilt the flying machine. More than two sets of blades may be mounted on the same column. Fig. 5 shows an arrangement wherein four groups of wings are used mounted on two columns E spaced from the body. The reciprocating mechanism which may comprise eccentrics Q3, Q<4> is housed in columns E and is driven by shafts K<5>, K<6> carried in tubular members connecting the columns E with a central column on the body to which columns E are braced. Shafts K<5>, K<6> are driven through shaft and bevel gearing from an engine G. The driving mechanism may be such as to cause rapid downward movement of the wings and a relatively slow upstroke. Two such arrangements are shown in Figs. 12 and 13. In the arrangement shown in Fig. 13, the speed of the point P may be from two to three times as great on the down as on the up stroke. A spring U may be compressed on the down stroke and assist in raising the wing on the up stroke.
Patent GB-384706-A (GB)
Title: Improvements in or relating to the treatment of artificial silk spinning cakes
IPC: D01D10/04
Filed: 1931-08-10
Abstract: <PICT:0384706/IV/1> <PICT:0384706/IV/2> The process of the parent Specification is modified by interposing a sleeve of thin permeable material between a cake of artificial silk and its carrier so that on passage of the treating liquid the sleeve clings to the inner thread layers of the cake where it is allowed to remain during drying and winding-off of the thread.  The sleeve material may be cambric. As shown in the drawings, a cake c rests on a carrier a with a certain amount of play.  The sleeve b, which may be somewhat wider in diameter than the inner diameter of the cake, is wider in diameter than the central or body part a<1> of the carrier. The sleeve b is moistened and drawn on to the central part of the carrier into the slots or openings of which, portions b<1> of the sleeve are pressed with the fingers.  The cake is then placed over the sleeve.  When the cakes are treated singly, the sleeve may be retained in position by an annular plate fitting over the top of the carrier.  When the cakes are treated in column form the upper end of each sleeve is clamped between its carrier and the next carrier above it.  If desired a soft rubber ring may be fitted over the reduced upper ends of the carriers so as to rest on the turned-over ends b<3> of the sleeves.  The pressure of the washing or other treatment liquid causes the sleeve b to puff out and cling to the inner layers of the cake.  The sleeve protects the threads and acts as a filter.  After drying, the threads cling to the sleeve, and it is possible to draw off overhead practically the whole of the cake on to cross-wound bobbins without collapse of the inner layers.  A ring of rustless material such as hard rubber may be laid on the cake during the drawing-off to avoid entanglement of the threads.

Title: Improvements in or relating to transmitters for use in electrical signalling systems
IPC: H04L25/04
Filed: 1930-07-09
Abstract: 358,924. Electric signalling systems. ASSOCIATED TELEPHONE & TELEGRAPH CO., 1033, West Van Buren Street, Chicago, U.S.A. July 9,1930, No. 22631/31. Convention date, July 15, 1929. Divided on 358,889. Drawings to Specification. [Class 40 (i).] Relates to an electric signalling system for transmitting information regarding the selling price of various stocks so that such prices may be indicated at a plurality of receiving points. The system is identical with that described in Specification 358,889, wherein the stocks are listed by means of one, two or three letters under the control of letter keys which when operated in accordance with a particular stock operate registers and a translator comprising a cross-connecting frame to effect the translation of the stock letters into a three-digit code. The price and nature of the quotation are recorded on further registers, and impulsing equipment is successively associated with all the registers to effect the transmission of impulses indicative of the registered quotation. Each digit transmitted to the receivers constitutes four impulses of alternate polarity, the strength of the impulses depending upon the setting of the registers. The claims however relate more particularly to the means for effecting the translation of code between the stock letter registers and the impulse transmitter. Specifications 16072/12, [Class 40 (iii), Telegraphs, Electric], and 358,984 also are referred to.

Title: Improvements relating to telephone systems
IPC: H04M15/10
Filed: 1935-08-12
Abstract: 455,669. Exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, Westminster, and CHRISTIAN, D. A., Morven, Charlton Road, Charlton, London. Aug. 12, 1935, No. 22674. [Class 40 (iv)] Meters are operated in accordance with the duration of calls by coupling individual component members to a continuously-driven common member. In one construction, Fig. 1, the coupling is effected by a rod DS geared at one end through a worm W and worm wheel WW to the counter-mechanism and carrying at its other end a roller KW, the rod being pivoted about the axis of the countermechanism so that the roller can be moved into engagement with a continuously-driven belt DB under the control of a magnet EM, the armature of which carries a forked member PA, PB engaging the rod. The belt is mounted on a horizontal mounting plate MP supporting a plurality of meters and is driven through worm-mechanism from a vertical shaft driving a plurality of belts. The magnet EM may be energized continuously or at intervals throughout the call. Two coupling magnets associated with driving means of different speeds may be provided, or it may be arranged that the magnet is energized one, two, or more times for each unit of time. In a second construction, Figs. 4, 9, the continuouslydriven member consists of a reciprocating rod BA mounted on flat springs FS and controlled by an intermittently-operated solenoid SO, and the coupling rod DS in each meter-mechanism is movable axially by the magnet EM so as to bring a ratchet RW into the path of one of a number of pawls PW on the rod BA. In a modification, the magnet EM controls a member acting on the pawl PW so that it is moved from inoperative position to operative engagement with the ratchet wheel. The speed of reciprocation of rod BA may vary with the time of day or the day of the week. In a third construction, Fig. 12, a coupling magnet EL energized throughout a connection applies a holding pawl PX to a disc PM which is then set by a second magnet EM responsive to impulses representing the rate of charge for the call. A finger AA on the rocking shaft DS then drops on to one of the teeth TC bringing a second finger FO into the path of a cam OC on a continuously-rotating shaft RT. At each engagement by the cam, the lifting of finger AA by an amount dependent upon the setting of PM causes a pawl PU to advance the countermechanism by a number of teeth corresponding to the rate of charge. In a fourth construction, Fig. 14 (not shown), the cam OC acts on a reciprocating rod having at its other end a pawl engaging a ratchet of the counter-mechanism, the number of teeth through which the member is stepped at each operation being determined by a mask or shield coupled to disc PM.

Abstract: 756,732. Making metal wool for heat exchangers. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Sept. 11, 1952 [Sept. 14, 1951], No. 22824/52. Class 83 (2). [Also in Group XIII] A thermal regenerator filling is made by feeding wire 58 of less than 50 microns hydraulic diameter by means of compressed gas through a nozzle 38 into a chamber rotating relatively to the nozzle. The wire is fed towards an apertured wall 55 at one end of the chamber, and is brought to rest in the form of numerous small curls in a plane perpendicular to general direction of fluid flow, initially by the apertured wall and subsequently, as the formation of the filling proceeds, by the outer face of the filling. The filling thus formed is subsequently compressed, e.g. by a die, in the main direction of flow of the compressed gas. The chamber as shown is annular and formed by the cylinders 53, 54 attached to the wall 55 and rotated by a motor 56 driving a friction wheel 57. The compressed gas is supplied through a pipe 34 to feed the wire into the chamber, and through a pipe 35 to assist in holding the curled wire in place. The wire is fed from a motor-driven reel 43 over a mandrel 46 to bend it before it reaches the nozzle 38.

Title: Improvements in treating a surface of a flexible self-supporting film with a reactive gas
IPC: C08J7/12
Filed: 1960-06-30
Abstract: <PICT:0882008/IV (a)/1> <PICT:0882008/IV (a)/2> A surface of a self-supporting film of organic thermoplastic polymeric material is treated with a gas reactive with the film material by continuously moving the film past a chamber through which the gas flows, the film forming one wall of the chamber and being in contact with and overlapping the edges of the chamber so as to prevent leakage of gas from the chamber.  The film and the reactive gas may be concurrently irradiated by electromagnetic waves of a length between 2,800  and 4,000 .  As shown, a film 1 is drawn continuously under tension over a gas chamber 4 which is a recessed section in an external planar surface 17 of a mandrel 6.  A reactive gas, such as a gaseous halogen, is introduced into the mandrel through the inlet 8 communicating with a receiving chamber 20 in turn communicating by means of a port 22 with the chamber 4.  Reaction byproducts and unconsumed halogen are discharged from chamber 4 through a port 21 into exhaust chamber 28, from which they escape through outlet 10. As the film is drawn upwards across the recess or chamber 4, the halogen makes contact with the surface of the film adjacent to the chamber.  A light energy source 14 such as a tubular fluorescent lamp may be positioned in front of the chamber 4 to allow light energy to pass through the transparent film to activate the halogen.  The reactive gas may also be sulphur dioxide or nitrogen peroxide, and the film material may be polyethylene or polyethylene terephthalate. Films treated according to the invention have improved ink adhesion and heat sealing properties.
