Patent GB-1509704-A (GB)
Title: Ignition devices
IPC: F23Q3/00
Filed: 1975-04-11
Abstract: 1509704 Control circuit TURNRIGHT CONTROLS Ltd 11 April 1975 [11 April 1974 14 Feb 1975] 16119/74 and 6295/75 Heading F4T An ignition device for a domestic gas burner of the type having spark ignition and a flame detecting circuit which inhibits sparking when the flame is established is adapted to be powered by a battery. In the first embodiment (Fig. 1) transistors T1 and T2 with resistance R1 and linked inductances L1 and L2 constitute a pulse forming circuit. The pulses, transformed through linked inductances L2 and L3, charge up a capacitor C1 until a gas-filled discharge device discharges (~ 220 volts) and the discharge pulse is transformed through transformer T1 to give a spark at electrode E1 and burner nozzle 3. When the flame is established a current flow across the electrodes and through a resistance R4 reduces the potential at the base of a transistor T4 and, as a result, transistors T3 and T4 which are normally non- conducting, start to conduct and bias off transistors T1 and T2 so that sparking is discontinued. If the flame goes out transistors T3 and T4 again become non-conducting and sparking is again started. In a further embodiment (Fig. 2), the charging of a capacitor C11 also causes the charging up of a second capacitor C12 until a neon lamp N11 breaks down and triggers a thyristor D13 which discharges the capacitor C11 through winding T11P to generate a pulse in T11S and a spark at the electrodes. A feedback line from C11 to the base of a transistor T11, normally non-conducting, causes it to conduct when a certain voltage at C11 is reached. This causes the pulses produced by transistor T12 to be reduced in amplitude and thus save battery power. Establishment of a flame short-circuits C12 to prevent it charging and hence discharge of C11. The part of the circuit including the burner nozzle electrode E11, winding T11S, resistor 14, capacitor C12 and neon N11 can be reproduced so that the circuit can control more than one burner.

Title: Ultrasonic liquid level sensing device
IPC: G01F23/296
Filed: 1964-04-21
Abstract: 1,039,392. Ultrasonic liquid-level sensing. W. R. L. KENT. March 15, 1965 [April 21, 1964], No. 16477/64. Heading H4D. An arrangement for sensing the level of a liquid, e.g. in a steam boiler, comprises an ultrasonic transmitting transducer and an ultrasonic receiving transducer each connected to one end of a respective ultrasonic waveguide tube, the opposite ends of the guide tubes being open and being so disposed relative to one another and to a desired position for a liquid-gas interface that, when the interface moves through the desired position, the flow of ultrasonic energy from the transmitter to the receiver changes by a detectable amount. In the embodiment of Fig. 2, waveguide tubes 22, 24 are mounted in a chamber 20 which communicates by a pipe 23 with the steam space of a boiler, and by a pipe 21 with the water space of the boiler. Piezo-electric transmitting and receiving transducers 30, 32 are coupled to the guide tubes 22, 24, respectively, and are protected from excess heat by a water-cooling jacket 33. Movement of the water-steam interface 28, through a position 27, causes a change in the ultrasonic energy flow from guide tube 22 to guide tube 24, which change is detected by receiving transducer 32 and a receiver unit 35 and may be utilized to control an audible alarm, a water feed pump, or the boiler firing equipment. The desired position for interface 28 may be set by adjusting the position of guide tubes 22, 24 within chamber 20 or the position of chamber 20 relative to the level of the water in the boiler. In the embodiments of Fig. 3 (not shown), the open ends of guide tubes 22, 24 are angled downwards, rather than horizontally, as in Fig. 2, so that ultrasonic energy is reflected into the receiving guide tube 24 by the water-steam interface 28, and a baffle 40 may be interposed between the tube ends to prevent energy reaching the receiving guide tube 24 other than by reflection from interface 28. In a modification of either embodiment, a plurality of ultrasonic receivers may be used with a single transmitter or with a plurality of transmitters, for detecting the presence of the interface 28 at a series of levels.

Title: Improvements in and relating to straight-bar knitting machines
IPC: D04B15/88
Filed: 1949-06-21
Abstract: 680,216. Knitting - machines. SVIT, NARODNI PODNIK. June 21, 1949. [June 21, 1948] No. 16483/49. Class 74 (ii). During the knitting of the last course of the toe of a stocking, each welt bar of a straight-bar machine is displaced from its rest position I to a preparatory position II in the vicinity of the frame needles, out of which, the machine running uninterruptedly, it passes automatically into an operative position III during the knitting of the initial course of the next stocking. The welt bar shaft 6 is rotated to move the welt bars from position I to position II, and from position III to position I (in drawing- off the fabric) by one or other of opposed pawls 23, 24 and coacting ratchets, constituting a drive A and actuated through linkwork by a lever 44 racked by rollers 48 on a yoke 50 keyed to a shaft 51 driven at half the speed of main cam shaft 55. The appropriate pawl and ratchet is selected, or both rendered inactive, by a lever 30 rocked, by the pattern drum 12 and acting, through linkwork and rack and pinion 25, 18, to position a rotatable slotted blanking cage 20. Positioning detents 125, 126 are, in the same way, rendered active or inactive. To rotate the shaft 6 in moving the welt bars from position II to position III and, at the same time, to activate an assisting auxiliary fabric draw-off device, the pattern drum 12 acts through a lever 110 to rock a pivoted extension 81 of one arm of a doublearmed lever 76 into the path of a cam 84 and, at the same time, through linkwork, to push a rack 91 against the action of a spring 97 until its first (low) tooth can engage with a pinion 61 on the shaft 6. The lifting face a of the cam 84 now rocks lever 76 clockwise (Fig. 1) against the pull of a spring 88, to bear against a pin 71 in a connecting rod 69 and traverse a rack 75, so rotating shaft 6, through gearing and, at the same time, traversing the draw-off rack 91 against the pull of its spring 97. At the end of this operation, a further step of the pattern drum 12 releases the pivoted lever extension 81, allowing a leaf spring 85 to bring it out of the path of cam 84 and the spring 88 to swing the lever 76 counter-clockwise, and, at the same time activate pawl 24, which proceeds to draw off the fabric, assisted by the pull of spring 97, acting through rack 91. As the rack 65 and connecting rod 69 are returned, during the rotation of shaft 6 by pawl 24 the free end of the connecting rod is rocked upwardly by the passage of a pin 72 thereon along a suitablyshaped groove 73, so that the pin 71 is lifted over the arm 75 of the lever 76.

IPC: B41M1/20
Filed: 1916-11-17
Abstract: 109,535. Barker, R. W., (American Bank Note Co.). Nov. 17, 1916. Intaglio-plate printing; printing in several colours; cylinder and like machines; inking-apparatus.-Relates to a method and machine for making multi-colour prints at one impression from engraved steel or other intaglio printing-plates. The different colours are applied in silhouette design to the corresponding parts of the plate, and the ink from the top or non-printing surface of the plate is then removed by an offset or transfer surface without rubbing contact of the plate, and surface. The plate is then polished, or wiped and polished, and is then ready to make the impression. The method of removing the surplus ink from the plate prevents mingling of the colours in the intaglio design. Figs. 1 and 2 show a " Milligan " press suitably modified for carrying out the method. Four beds 5, 6, 7, 8 each carry a printing plate in succession beneath inking mechanism A, ink-removing mechanism B, plate wiping and polishing-mechanism C, and an impression roller D. The inking-mechanism shown is for three-colour work and comprises three inking rollers 11, 14, 17 with transfer rollers 12, 15, 18 and fountain and distributing rollers 13, 16, 19. The rollers 12, 15, 18 carry planographic or relief ink-receiving surfaces in silhouette design corresponding to the differently coloured parts of the printing-plate. The inked designs are transferred to the inking rollers 11, 14, 17 and from thence to the plates on the beds 5, 6, 7, 8. The ink-removing mechanism B comprises a roller 20 with a rubber or other transfer surface, which rolls on the plate without rubbing contact. The roller 20 is preferably positively driven to avoid slipping and is cleaned by a steel roller 21, scraper 22, and pad 23. The roller 20 and its cleaning mechanism may be duplicated at shown in Fig. 1. The wiping and polishing mechanism C is of ordinary construction comprising bands 29, 31 passing round pads 28, 30.

Title: Improvements in and relating to dental rubbers and to the manufacture of dental plates
IPC: A61K6/083
Filed: 1922-07-14
Abstract: 224,032. Joannides, C. July 14, 1922. India-rubber, colouring; vulcanizing; plastic compositions containing india-rubber of different degrees of vulcanization.-Dental rubber consists of a mixture of unvulcanized or " partly vulcanized " rubber with " semi-vulcanized " rubber or with rubber of a different colour vulcanized to any degree. " Partly vulcanized " rubber is defined as rubber which retains substantially the plasticity and adhesive properties of raw rubber, while " semi-vuleanized " rubber is vulcanized to a degree permitting it to be ground up, although it has not the properties of hard rubber and is still capable of swelling in benzine. The more highly vulcanized ingredient is ground or shredded to any desired size before being incorporated with the plastic rubber, and by incorporating shreds of one or more shades of white, pink, or red with plastic rubber of another colour the veined appearance of the natural gum is imitated. The slight vulcanization of the plastic rubber may be effected during the mixing of the ingredients in the presence of a suitable accelerator. The final vulcanization to which the denture is submitted after moulding may be further accelerated by the admixture of an accelerator with the plaster composing the mould. One of the Provisional Specifications describes the use of a mixture of unvulcanized rubber and ground rubber of the same colour vulcanized to any desired degree. Reference has been directed by the Comptroller to Specification 174,471.
