Inventor: PHILLIPS JOE
IPC: G07F17/32
Filed: 2009-01-17
Abstract: An entertainment machine comprises a main display device 9, 11 used to play a main game, and at least one supplementary play feature 15; a player control 25 for selecting operation of the (or at least one) supplementary play feature 15 in place of an available main game; and a credit monitoring means (12a, Fig 2) for determining the credit level established for play. The player control 25 is operable in response to the established credit level such that the supplementary play feature 15 available for selection varies in response to the established credit level. With this arrangement enhanced opportunities for player entertainment arise in so far as the player can choose to implement a supplementary play feature 15 at the start of a game as an alternative to the usual procedure of playing a main game followed by a supplementary play feature 15. Furthermore, the supplementary play feature 15 made available may be varied in nature or operation to ensure compliance with local requirement and/or ease of implementation and thus an attractive wager for a player.

Title: Boiling sensor for water-boiling appliances
Inventor: HARVEY DAVID ROBERT
IPC: A47J27/21
Filed: 2009-11-17
Abstract: A water-boiling sensor usable in electric kettles, or other water-boiling appliances incorporating an electrically powered heating element, is designed to reliably detect when the water boils. It utilises a capacitive detection element comprising electrodes 10, 12, which disposed in contact with water in the appliance and are connected to an oscillator 16 or other circuit, which generates electrical signals that are influenced by the capacitance between the electrodes, and which exhibit a peculiar and repeatable characteristic response when the water boils. Electrical circuitry 18 is provided to recognise electrical signals having the aforementioned characteristic response and to then develop control signals which disconnect the power from the heating element when the water boils. The sensor is wholly electronic and preferably can also be used to detect the water level, and calculate the expected boiling time. A warning device may also be included to alert to an extended boiling time, which may be indicative of an issue with the appliance.

Title: Improvements in the production of filaments, threads, yarns, ribbons and the like from cellulose esters and ethers
IPC: D01F2/30
Filed: 1929-03-28
Abstract: 334,195. British Celanese, Ltd., Taylor, W. I., and Roberts, R. P. March 28, 1929. Cellulose esters and ethers, processes for making filaments jrom; apparatus for making filaments.-Filaments, ribbons, &c. of relatively reduced lustre are obtained directly by the dry spinning method by adjusting the temperature of the spinning solution to a value below that of the evaporative medium and below the minimum temperature required to produce highly lustrous products. A reduction of 10-20‹ C. is generally sufficient to effect a substantial reduction in lustre; still further reduction gives completely matt products. The temperature of the spinning solution may be controlled separately from that of the evaporative medium, for example, by employing the means described in Specification 320,632, the spinning solution being passed through an attemperating device and thereafter insulated against the effect of all extraneous influences. As an alternative the necessary reduction in the spinning solution temperature may be obtained by drying the heating effect of the evaporative medium, for example, by employing for the spinning jets material of relatively low conductivity and having a highly polished surface, or by an increase in the denier of the filaments being spun, or by increasing the speed of spinning. Delustred products of any cross-section may be obtained; thus, to obtain products of rounded section there may be employed cellulose derivatives of high viscosity characteristics, or highly concentrated spinning solutions; and the evaporative power of the air may be adjusted as by the use of the collector devices described in Specification 300,998; further, cellular or tubular products may be obtained by concentrating a sufficient supply of heat at the region of the nozzles according to the process of Specification 324,899. In view of the low temperature of the spinning solution it may be necessary to give the filaments a relatively long run in the spinning chamber, for example, by adopting the forms of apparatus described in Specification 315,729. The filaments may be associated into yarns continuously with their production as by the use of cap-spinning devices as described in Specification 198,023. The process of the present invention may be combined with that of Specification 333,504, in which wetting agents are added to the spinning solutions; and the products may be treated with abrasive material according to the process of Specification 328,247 for the purpose of still further diminishing their lustre. Spinning solutions of, for example, cellulose acetate, formate propionate, or butyrate, or methyl, ethyl, or benzyl cellulose may be used in the process.

Title: Improved spring coiling machine
IPC: B21F3/06
Filed: 1966-03-08
Abstract: 1,110,683. Coiling wire; shearing. TORRINGTON MANUFACTURING CO. 8 March 1966 [29 July, 1965], No. 10102/66. Headings B3E and B3W. A spring coiling machine comprises means for feeding wire to engage an arbor 36, and a coiling tool 38 which engages the wire to bend it into a coil of predetermined diameter whilst permitting the wire to be moved in a lateral direction by first and second pitch tools 40, 42 which bend the wire to introduce the desired pitch. In a first embodiment, Figs. 2 and 3, wire 20 is fed through a quill 32 to engage a projecting portion 100 of the arbor 36. The wire then engages a cylindrical coiling roller 112 which bends it upwards to coil about the arbor 36, contacting an adjustable recoil tool 44, which is clamped to the arbor, as it does so. When the coil is completed the wire feed stops and a knife 48 is swung downwards by rotation of an arm 256 which pushes down an arm 248 against the action of a spring 250 so that a knife element 242 co-operates with a shearing edge 46 on the recoil tool 44 to cut-off a length of coiled spring. The angular position of the arbor and hence of the tools 40, 42, can be adjusted by rotating it in a mounting 96. The diameter of the coil produced depends upon the position of the coiling tool 38 which can be adjusted. For the production of springs having diameters which vary from end to end the tool 38 may be moved in timed relation with the wire feed rolls by a cam operated link and lever mechanism, Fig. 4 (not shown). When springs of decreasing diameter are being wound the radius of the initial portion of the spring is increased by providing a " hump " on the cam of the link and lever mechanism, the tool then moving sharply towards the centre of the arbor and to increase the radius of the bent wire. Twisting of the wire as it is wound is controlled by antitwist means in the quill 32. As shown for winding wire of square cross-section the quill is provided with a square bore. The quill may be rotated about its axis to control the degree of twist and may be rotated in timed relation to the wire. When the pitch of the spring has to vary throughout its length the pitch tool 42 can be moved in timed relation to the wire feed rolls by a cam operated link and lever mechanism. In another embodiment, Figs. 7 and 9, wire 20a of circular cross-section is advanced by feed rolls 266, 268 through pre-cast units 270, 272 which introduce a slight bend into, or remove it from, the wire before it is passed through pairs of grooved anti-twist rolls 276, 278 to an arbor 282 about which it is coiled by contact with a coiling tool 286. At the point 284 where the wire contacts the arbor a V-shaped groove is provided thereon into which the wire is pressed by a grooved roller 288 to further resist twisting of the wire at a point close to the pitch tools 290, 294. The coiling and pitch tools may be arranged closer to the point at which the wire engages the arbor. Figs. 11, 12 (not shown).

Abstract: 1349715 Attaching spiked plates A MOTTA 20 April 1971 [28 April 1970] 10111/71 Heading B4C [Also in Division F2] Two wooden members 33, e.g. members of a picture frame, are joined together by a flat metal angle plate 2, having teeth projecting from its plane at right angles, by a machine which uses a feed belt 1 of plates 2 joined at their ends by integral strips 4, each plate 2 being separated from the strips 4 by punching, and driven into the members 33. The strips 4 of the feed belt 1 pass along guide slots 31 of a table 28. A movable assembly comprises beams 13, 14 connected together by slide rods 12, the beam 14 carrying a cylinder 15 containing a piston 16 connected by a rod 19 to a punch 21. With the members 33 positioned against stops 32, the upper chamber 48 of the cylinder is vented, allowing the assembly to descend until a pad 34 on the beam 13 engages the members 33. Then the lower chamber 49 is pressurized to drive the punch upwards to separate a plate 2 from the belt 1 and force its teeth into the members 33. As the assembly is raised again, a roller 43 on the beam 13 rocks a lever 42 about a fulcrum 41 so that a pawl 46 advances the feed belt 1 sufficiently to bring the next plate 2 into position above the punch 21. The machine is claimed in Specification 1,349,716.

Title: Improvements in or relating to electric arc welding apparatus
Inventor: SEVENCO ALEXANDER JURA
IPC: B23K9/09
Filed: 1965-03-11
Abstract: 1,112,511. Arc welding systems. LINCOLN ELECTRIC CO. Ltd. 18 Feb., 1966 [11 March, 1965], No. 10438/65. Heading H2H. An apparatus for dip transfer welding has a means responsive to the termination of the short circuit current to inject a pulse of current into the weld. A gas shielded continuously fed arc electrode 20 is fed from a primary supply 70. On cessation of the welding current, a transistor pair 95, 96 will out off and a transistor 97 will fire during the charging of a capacitor 98 causing, due to the current change in a transformer 100, a thyristor 76 to shunt a resistor 78 in a secondary supply 71-75. At the same time another transistor pair 83, 84 switches off and a transistor 85 fires during the charging of a capacitor 86 blocking a transistor 88. Discharge of a capacitor 89 causes transistor 90 to fire thus through transformer 91 firing another thyristor 77 which blocks the thyristor 76. The difference in the time constants of the two transistor circuits determines the pulse length.
