Title: Process and apparatus for burning liquid fuel
IPC: F23D5/00
Filed: 1932-10-10
Abstract: 401,868. Liquid - fuel furnaces. ELKINGTON, H. D., 20, Holborn, London.- (Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij ; 30, Carel van Bylandtlaan, The Hague.) Oct. 10, 1932, No. 28229. [Class 51 (i).] Combustion products, returning to furnaces.- Liquid fuel in a relatively finely divided or thinly spread but non-atomised state, for example in relatively large drops or in a thin liquid layer or film or small liquid currents, is brought into contact with combustion air mixed with such a proportion of the very hot combustion gases, which are thereby returned to the zone of incipient combustion, that the temperature of the mixture obtained is sufficiently high to cause ignition of the fuel upon the mixture coming in contact therewith. In the form shown in Fig. 1, fuel is supplied in drops to the combustion chamber 1 from a reservoir 3 by a tube 2. Air, supplied by a blower 15 through a tube 4, and combustion products, withdrawn from the chamber 1 through the conduit 6 by the injective action of the air supply, are mixed in and delivered through the nozzle 7. Secondary air is supplied through the pipe 8 and apertures 9. In the form shown in Fig. 2, the combustion chamber 1 is approximately cylindrical, with a tangential air inlet 4 and a central outlet 10. Oil is supplied through a tube 2, and spreads on a plate 14. The air and combustion products assume a spiral path and so intermingle. The inflowing air passing under the plate 14 keeps it cool. In a third form, an elongated chamber is provided at its closed end with a plate on which the oil spreads, and at the other end with a flap-controlled air inlet and an outlet, so that the combustion products pass towards the outlet in contact with the incoming stream of air. Specification 204,951, [Class 51 (i), Furnaces and kilns, Combustion apparatus of], is referred to.

Title: Charge-coupled logical devices
IPC: H03K19/08
Filed: 1973-06-14
Abstract: 1433027 Charge-coupled devices INTERNATIONAL BUSINESS MACHINES CORP 14 June 1973 [3 July 1972] 28265/73 Heading H1K A charge-coupled device for logical operations includes means to induce spaced first and second potential wells, the transfer path between the wells including a potential barrier 48, Fig. 2A, to limit the capacity of charge of the first well, and input means adjacent the first well to introduce, during a first period, charge into the first well, the transfer path allowing charge in excess of the capacity of the first well to transfer to the second well. The device shown forms an AND gate, the wells being formed in semiconductor material 20 by electrodes 24, 26 on an insulating layer 22, the electrodes being energized from a common line 42. The input means is formed by electrodes 28, 30, Fig. 1, together having a charge capacity in excess of that of the first well; if both inputs are a logical "1" this charge overflows from the first well into the second to produce a logical "1" at output electrode 32 during a second period. If, however, only one or neither of the inputs is at a logical "1", the charge transferred to the first well is insufficient to cause overflow to the second well, producing a logical "0" at the output electrode. Charge subsequently transferred from the well under electrode 24 may be used as a logical OR output. The potential barrier 48 may be produced by a gap D between electrodes 24, 26; or a further electrode (50, Fig. 4, not shown), also connected to line 42, between electrodes 24, 26 may be produced on a thicker insulating layer. In a modification, an Exclusive OR output is created at an additional electrode (52, Fig. 5, not shown), by a control electrode (54) which allows charge under electrode 24 to pass unless a sensing electrode (56) detects an AND charge under electrode 26. In a further modification (Fig. 9, not shown) Exclusive NOR function is obtained by the addition of a field electrode (76) adjacent electrode 24, and a charge generating diffusion (78) adjacent control electrode (54), electrode 26 being disconnected from electrodes 24 and (50). If no OR charge appears under field electrode (76) a charge is allowed to pass from diffusion (78) to represent a logical "1" output; but if sensing electrode (56) detects a charge, control electrode (54) prevents this, so producing a logical "0".

Abstract: 1,147,498. Selective printing machines. ANELEX CORP. 20 June, 1967 [20 June, 1966], No. 28499/67. Heading B6F. In a printing device comprising means, such as a continuously-rotating cylinder 11 with circumferential rows of type, for presenting a set of type to each of a plurality of character positions along a printing line, a hammer mechanism is provided consisting of a number of drive hammers 13 each having a width along the printing line spanning a plurality of character positions, and each having associated therewith an interposer or printing hammer 15 of character width, the hammers 15 being moved stepwise in the line direction to print a line. As shown the drive hammers 13 have a width corresponding to four characters, and each hammer 15 is moved leftward three steps from its initial rightward position i.e. a line is printed in four cycles of the machine. The hammers 13 are electromagnetically-operated as described in U.S. Specification 3,266,418. The hammers 15 are of spring steel or other hard flexible metal and are formed as part of a carriage 19 which is moved in the line direction by a link 47 having followers engaging a cam 53. The cam 53 is rotated one quarter of a revolution for each actuation of a wrap-around spring clutch 25 by a pivoted arm 41 actuated by a solenoid at each revolution of the drum 11 under the control of timing circuits. The cam 53 operates to move all the hammers 15 one character width at each quarter revolution and then to return them to their initial positions ready for printing the next line. The mechanism may, however, be designed to move the interposer hammers 15 in opposite directions during the printing of successive lines. Instead of using a cylinder 11, the sets of type may be arranged on chain type carriers.'

Abstract: 173,111. Chambers, T. M., and Lochhead, W. A. Oct. 15, 1920. Lift doors, locking and unlocking.-The unlocking of a pit-shaft gate is prevented until the cage is at rest opposite to it by mechanism connected by reducing-gearing to the winding-engine shaft. A crank 11 on the lock 3 is connected by a rope 10 to a latch member 1 formed with a shoulder 8. A disc 4 during the travel of the cage maintains the shoulder 8 in engagement with the shoulder 9 on the fixed frame 2 and so prevents raising of the lock 3 by hand. The disc 4 is driven from the winding-engine shaft through reducing- gear and has a notch 12 cut in its edge at a point which is adjacent to the latch 1 when the cage is opposite the gate. As the latch is weighted and suspended so as to tend to swing towards the disc, when the disc stops the latch passes into the notch and the shoulders are disengaged, thereby permitting the actuation of the lock 3. The edges of the notch are cam-shaped and force the latch back into the position shown as soon as the engine is started.

Abstract: 1,168,285. Laminates. POLYMER CORP Ltd. 23 June, 1967 [25 June, 1966], No. 29198/67. Heading B5N. Fibres are secured to an openweave fibrous substrate by applying a thermoplastic film to the substrate in a heat-softened condition, applying pressure and thereafter cooling. As described, a carpet is formed from an openweave primary jute 10 tufted with woollen pile fibres 11 and a scrim 14 also of open-weave jute secured to the underside of the primary jute by a thermoplastic rubber film 13 preferably of a block copolymer of the form polystyrenepolybutadiene-polystyrene with a molecular weight of about 60,000 and compounded with a microcrystalline paraffin wax and pentaerythritol ester of hydrogenated rosin. An alternative block copolymer is of the form polyisoprene - polybutadiene - polyisoprene with the polyisoprene blocks hydrohalogenated. The film may be prepared by solution casting, chill-roll casting or extrusion blowing, and have a thickness of between 5 and 25 thous. The tufted primary jute 10, the thermoplastic film 13 and the scrim 14 are fed along parallel but spaced paths and then the tufted primary jute and the scrim are passed around steamheated drums 26, 27 while the thermoplastic film is softened by radiant heaters 30, 31. The three layers are then brought into contact and passed between heated nip rollers 32, 33 and finally cold nip rollers 34, 35, after which the upper layer is subjected to the action of a pile-beater roller 36, or the carpet may be passed through a steam box. The drive is applied to a wind-up roller 37 and, preferably through a slipping clutch, to the drums 26, 27. A small amount of latex may be applied to the tufted primary jute prior to the application of the thermoplastic film. A carpet may be made without the scrim 14 in which case the drum 27 and the heated rollers 32, 33 are not required. In this case, the lower cold roller 35 can carry an embossing pattern.
