Title: Apparatus for playing a game
IPC: A63F7/00
Filed: 1929-06-12
Abstract: 329,866. Wallis, A. R., and Baines, R. H. June 12, 1929. Table games.-Apparatus for playing a game comprises an undulatory passage or runway for pieces such as balls or rollers, and just wide enough to allow such a piece to travel therein from end to end, and means whereby a piece in the passage or runway may be caused to travel freely along the latter, to fall therefrom if its speed be too high or too low through a side opening or by-pass constituting a hazard. A coin or piece 17 inserted in a slot 16 may be driven along a track 12 by striking a pivoted striker 23. If the speed is too low the coin falls through a side opening 21, if too high it jumps a gap 19 and is deflected through an opening 22. If the speed is correct, the coin falls through the gap 19 and comes to rest on a lower track along which it may be similarly propelled, and so on for successive tracks until, if the openings or hazards 21, 22 are all successfully avoided, the coin is finally directed into a hole 33 whence it falls upon a detent 34 and permits the player to draw out a slide 37. The slide 37 forms the floor of a glazed compartment 28 into which some of the coins previously lost down the openings 22 have collected. On pulling out the slide these coins are delivered to the successful player down a shoot 30.. Buffers of felt, sponge, &c. may be provided at the ends of the tracks instead of deii,ectors. The tracks may be adjustable in inclination or shape, and may be decorated to represent a golf course.

Title: Antenna for producing a rotating cardioid pattern
IPC: H01Q3/26
Filed: 1975-04-30
Abstract: 1505375 Aerials; rotating cardioid beacons INTERNATIONAL STANDARD ELECTRIC CORP 30 April 1975 [7 May 1974] 18045/75 Heading H4A A radio beacon for producing a rotating cardioid pattern comprises four elements 16 fed in phase which radiate an omnidirectional carrier pattern and a sideband pattern of two orthogonal figuresof-eight, the sideband energy being fed via a goniometer, in which the radiating elements 16 excite a rotationally symmetrical horn-type radiator formed by the opposed convex sides 6, 7 of two electrically conducting dish structures 1, 2, the elements 16 being arranged parallel to the axis 3 of the horn-type radiator on the convex surface 7 of the lower dish 2. Each element, associated with a sensor 17 and conducting bar director 11, is disposed at the corner of a square. The directors 11  serve to mechanically interconnect opposed dish structures 1, 2. The upper rim 4 is narrower than rim 5 to give an upward tilt to the radiation pattern. The central bar 12 serves as an input impedance matching device. Doward side lobes are reduced by two interfitting hollow conducting cylinders 13, 14 connected by a ring 15. Sensors 17 are shielded miniature loop aerials responding only to the magnetic fields of the currents flowing on the elements 16 and serve to check the quadrature relationship between the omnidirectional and sideband pattern currents. Quadrantal errors are practically reduced to zero (Fig. 3c, not shown) by varying the radial distance between an element 16 and its associated director 11.

Title: Improvements in electron discharge apparatus
IPC: H01J25/78
Filed: 1940-12-23
Abstract: 577,280. Electron discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 23, 1940, No. 18048. Convention date, Dec. 22, 1939. [Class 39 (i)] Electron discharge apparatus comprises a magnetic structure for producing a static magnetic field which gives a wave-like form to an electron beam passing through it, means for varying between limits any or all of the conditions of the beam as regards its velocity, position, and direction under which it enters the magnetic field, thereby varying the wave-form taken by it in the magnetic field, and an output system the effect of the beam on which varies with the wave-form of the beam, whereby the variation of the entry conditions of the beam excites oscillations in the output system. The form shown, with the parts separated, comprises a cathode 12 and an apertured accelerating electrode 13 producing an electron beam which passes through an off-centre aperture 17 in a plate 16 closing the end of a hollow conductive structure 15 of rectangular cross-section. In passing through this structure the beam is acted upon by transverse static magnetic fields produced by elongated electromagnets 19, 20, between the poles of which the structure 15 is situated. Owing to the fact that the beam enters the structure 15 to one side it is deflected by the field of the magnet 20 towards the other side, then back by the field of the magnet 19, and so on, the beam being thus given a waveform path as shown by A, Fig. 4., and finally reaching collector electrodes 29, 30 connected in push-pull across a tuned circuit. By varying the potential of the accelerating electrode 13 the velocity of the beam is altered, and hence the number of reversals of transverse movement which it undergoes before reaching the collector electrodes, so that the beam may be transferred from one to the other of the electrodes 29, 30, as illustrated by the paths A,B respectively, by suitable variation of the potential of the electrode 13. By cyclic variation of this potential a cyclic variation in voltage across the electrodes 29, 30 is produced by the transfer of the beam from one to the other, and by making the range of variation of potential of the electrode 13 sufficient to cause a change greater than. one in the number of beam reversals a corresponding number of reversals of potential across the output electrodes occur for each cycle of the potential applied to the electrode 13, producing frequency multiplication. In a modification, the same results are obtained by varying the direction in which the beam enters the magnetic field, instead of its velocity, for which purpose a pair of electrostatic deflecting plates are arranged between the electrode 13 and the end of the structure 15. The device may be used in the system of frequency modulation described in Specification 534,757.

Patent GB-1511806-A (GB)
Title: Error detection and correction in data processing systems
IPC: G06F11/10
Filed: 1976-05-04
Abstract: 1511806 Error detection and correction DATA GENERAL CORP 4 May 1976 [7 May 1975] 18211/76 Heading G4A A code generator 18 generates for each word to be written in a memory 13 a plurality of odd and even parity check bits each derived from a different combination of bits of the word, each combination having the same number of bits; the parity check bits are written in the memory 13 together with the corresponding word and when the parity check bits and word are read from the memory 13 the code generator 18 derives error bits by performing further parity checks each on one of the combinations of bits selected during the write operation plus the corresponding parity check bit. The error bits are decoded at 20; if a single bit error is detected it is corrected, by complementing the bit in error, and the corrected word is derived from a gate 23 and rewritten in the memory 13, at the same address as stored by an address register 24. Each word to be written may be a 16-bit word supplied to a register 16, code generator 18 producing 5 parity check bits, each from 8 bits of the word which are supplied to the register 16. Each error bit is produced from 9-bits of the parity check bits and word read from memory 13 and entered into register 16; the error bits supply a unique code for each one-bit error, unique codes for all zeros or all ones read from the memory and eight codes which indicate multiple errors. Code generator 18 may form three of the parity check bits and error bits by odd parity checks and the other two by even parity checks. Selective setting of two flip-flops (95, 96, Fig. 10, not shown) allows checking of the operation of different parts of the error detection and correction system.

Title: Improvements in and relating to Alternating Current Relays.
IPC: H01H51/30
Filed: 1917-12-08
Abstract: 115,595. Waygood-Otis, Ltd., (Otis Elevator Co.). Dec. 8, 1917. Alternating-current relays; protective arrangements.-An alternating-current relay, particularly for use as a reverse phase or low voltage device, has two windings 6, 7, with substantially V-shaped cores, and an aluminium plate armature 18 carried by rods 19 from a journal 17, the bearing being on one side of the windings and the armature on the opposite side. The journal carries on a bracket 24 a copper contact 26 permanentlv connected by a flexible lead 28 to a terminal E. A weight 23 partly counterbalnaces the contact 26. The fixed contact 29 is of carbon adjustably mounted on the terminal bracket 31. The windings 6, 7 are connected to different phases of a two or three phase supply circuit, the contacts 26, 29 closing a relay circuit for a main switch. On phase reversal in one of the windings or on excessive drop in voltage, the contacts open by gravity and open the relay circuits. The windings may be in series with the stator windings of a motor, so that if one of the stator winding circuits is opened the relay is unbalanced and the main switch opens.
Patent GB-459208-A (GB)
Title: Improvements in and relating to automatic record-changing talking machines
IPC: G11B17/16
Filed: 1935-07-02
Abstract: 459,208. Gramophones. OFFEN, F. J., and GARRARD ENGINEERING & MANUFACTURING CO., Ltd., Newcastle Street, Swindon. July 2, 1935, No. 18300/36. Divided out of 459,155. [Class 40 (ii)] In a gramophone &c. having automatic record-changing mechanism, the driving-motor is stopped automatically by means which are rendered operable by release from the weight, or part weight, of the last of a batch of records or from the weight of a single record. As described with reference to a machine in which records are released one by one from an offset spindle 1 by the reciprocation of a support 2, the spindle 1 is mounted in a fixed sleeve 6 and guided by a fixed member 10 within the sleeve, so that the spindle may move vertically, but cannot rotate. A pin 11 slidably mounted in the member 10 rests on a lever 12 which is depressed as long as a record is supported on the spindle 1, and so prevents a lever 17 governing the driving- motor switch from moving to a position to stop the motor. When the last record has been deposited on the turntable 8, a spring 14 is effective to swing the lever 12, thus permitting the lever 17 to move to motor-stopping position. The motor switch and brake are governed by a pin 27 working within a slot 31 in a re-setting bar 28 controlled by a knob on the motor board, the pin 27 being actuated by a crank 26 on a spindle 25 carrying the lever 17, which has an arm 20 coupled to the lever 17 by a spring and driven by a cam 19 in such manner that movement transmitted to the arm 20 merely stretches the spring until the release of the lever 12 allows the arm 20 to communicate its motion to the lever 17 and so stop the motor. Specifications 399,172 and 450,966, are referred to.

Title: Method of producing sugar from sugar-bearing raw material
IPC: C13B10/00
Filed: 1963-05-09
Abstract: In producing crystalline sugar from raw material such as sugar-cane, sugar-beet and dates, the unheated material, preferably in the form of grated shreds, slices or cossettes, is subjected to a gas, e.g. air, at high pressure and normal temperature, the pressure is suddenly reduced to normal atmospheric pressure, to burst the cells of the material and reduce it to pulp, from which the sugar is extracted in two or more consecutive, countercurrent diffusions with cold, e.g. ice-cold, water.  The diffusion juice is purified by treatment with ozone and/or milk of lime and/or aluminium sulphate and/or by electrophoresis, followed by filtration and is then chilled so that ice is formed and sugar crystals are deposited from the resulting concentrated syrup.  The ice is removed and the sugar crytals are separated from the mother syrup, washed with alcohol and dried.

Title: Improvements in or relating to braiding and like machines
IPC: D04C3/00
Filed: 1920-07-03
Abstract: 146,429. Wardwell, S. W. Dec. 12, 1913, [Convention date]. Braiding-machines. - The mechanism for deflecting the yarns from one set of supplies in and out around the supplies of the oppositely-moving set in the machine described in Specification 13121/11 is modified by reducing the number and weight of the parts and by providing for greater accessibility and for easier and more economical methods of construction. The two sets of supplies Y, X are mounted so as to be moved by turrets B, C driven in opposite directions on balls b, c, by means of bevelgears B<1>, C<2> meshing with a bevel-pinion E on the driving- shaft D. Pins b<2>, c<1> attach the gears B', C<2> to the turret B and to an extension C<1> of the turret C respectively. The upper supplies X are mounted on carries G having lenticular deck portions g and depending arcuate runners g<1>, wedgeshaped in cross-section, which run in a gapped track H forming part of the outer rim of the turret B. The supplies X are driven round the track H by pairs' of reciprocating drivers J mounted in radial guideways c<3> of the turret C and carrying rolls j operated by the waved groove k of a plate K set in the rim b<3> of the turret B. The movements of the drivers J to engage and release the carriers g are such that while each carrier is at all times engaged by one of its drivers, the yarns y are free to pass the inner sides of the carriers without obstruction from the drivers. The drivers are held in place by the overlapping conical rim l of a central bonnet L, which carries a beat-up device N. The controllers 0 for guiding the yarns y so that they pass under and over the carriers g in regular order consist of stiff wire or sheet-metal crotch-portions O<1> and off-set sliding portions O<2> the foot-pieces o of which are held by springs S against the operating edge p of a fixed cam P. Normally, the yarns y rest in a central V-depression o<4> and are slightly deflected by the action of the cam P to engage the projecting points g<2> of the runners g<1>, the curved edges of the carriers g then forcing the yarns y along the curved parts o<2> or o<3> of the controllers. The cam P may be attached to the brake-ring T which is operated by a stop-motion as described in Specification 16430/11. The cam P is removable, and by changing it for others with different contours, various patterns of braid are obtainable; or the controllers O may be operated by two or more removable cams.

Title: Polyitaconic anhydride and process for preparing polyitaconic anhydride and polyitaconic acid
IPC: C08F8/00
Filed: 1965-05-03
Abstract: Homopolymers of itaconic anhydride are claimed per se which may be converted to the acid by treatment with water.  The polyitaconic anhydride may be prepared by polymerization in an inert organic solvent from which the polymer separates as a finely divided powder, e.g. benzene, chloroform and/or petroleum ether, and in the presence of a catalyst, e.g. dibenzoyl or dilauryl peroxide, diisopropyl or dicyclohexyl percarbonate, or azoisobutyronitrile, and optionally a co-catalyst, e.g. cobalt oleate, which is soluble in organic solvents.  The catalysts may be added continuously during polymerization. The polyitaconic anhydride while being dissolved in water may be heated and evolves carbon dioxide, or the solution may be treated with ferric chloride solution to produce an iron complex. The polyitaconic anhydride may be dissolved in methanol to produce the semi-ester.ALSO:Itaconic anhydride is prepared from itaconic acid by heating the acid with acetyl chloride and then distilling off the excess acetyl chloride under atmospheric pressure and the acetic acid formed under vacuo, the temperature being kept below 90 DEG  C. to prevent the itaconic anhydride from being converted to citraconic anhydride.
