Abstract: 999,131. Heating apparatus. N. W. GILBERT. Aug. 16, 1961 [May 16, 1960], No. 17282/60. Heading B5A. [Also in Division F4] A preheater for pellets, tablets or like preforms compressed from a powdered plastic material, is formed with at least one tunnel which is open at each end and is, throughout its length, of uniform cross-section, the roof and floor of the tunnel being two parallel plates 3, 3a which are relatively adjustable to alter the depth of the tunnel, each side of the tunnel consisting of an upper side plate 10a extending downwardly from the roof and a lower side plate 10 extending upwardly from the floor in overlapping relation and sliding contact with the inner side of the upper side plate, and means being provided for heating at least one of said parallel plates to a controlled temperature at which the preforms contained within the tunnel are heated to a temperature below the curing temperature of the plastic material. As shown the heating is by two induction coils 12 embedded in each plate 3, 3a of steel or other magnetizable material. Alternatively other heating means-for example electric resistance elements, steam, gas or like burners, or hot water or oil-may be provided. Each plate is surrounded by heat insulating material 4, 4a and boxes 5, 5a. The roof and box 5a are moved vertically, by rotating the rods 9 in the tapped holes of the supporting bars 6a. External troughs or tables 15, 16, Fig. 1 (not shown), at each end of the tunnel assist in the loading and unloading. The plates 5, 5a may contain a thermostat and a thermometer. To avoid overheating the undersides of the objects in the tunnel the tunnel floor may be ribbed longitudinally or preferably a false floor installed with an air space between the actual and false floor. Multiple tunnels may be placed side by side or superimposed and in the latter case one plate may serve the dual purpose of a floor for one tunnel and a roof for another.

Title: Improvements in variable speed gears
IPC: G05G9/10
Filed: 1931-06-17
Abstract: 372,978. Change-speed gearing. WOLSELEY MOTORS (1927), Ltd. and BODEN, O., Drew's Lane, Ward End, Birmingham. June 17, 1931, No. 17538. [Class 80 (ii).] In change-speed gearing suitable for vehicles, both a direct clutch drive and an overdrive are brought into action by the same pivotal movement of a control lever 21 ; for the direct drive, strikers 17, 18 are moved simultaneously, while for the overdrive, the lever 21 is depressed so as not to move the striker 17 along with the striker 18. The neutral position is shown in Fig. 1. A countershaft 12 is constantly driven from a driving shaft 5 by a pair 14, 13. A doublehelical gear 11 splined on the shaft 12 is slid axially along with its mating gear 10 on a sleeve 8 loose on an inner sleeve 3 splined on a driven shaft 1. For the direct drive, the sleeves 3, 8 are moved to' the right simultaneously to the position of Fig. 2 in which clutch teeth 4 on the sleeve 3 engage and are driven by clutch teeth 6 inside the gear 14. The overdrive through the train 14, 13, 11, 10 is brought in when the sleeve 8 alone is slid to the right from the position of Fig. 1 to that of Fig. 3 in which clutch teeth 9 on the sleeve 8 engage the teeth 4 and the gear 10 is clutched to the shaft 1. Second speed is effected by sliding the striker 17 to the left of Fig. 1 to engage a pair 15, 16. First speed and reversed drive are effected by sliding another gear &c. from a third striker 25, Fig. 4. The strikers slide on fixed guides 20. In neutral, gaps 22, 23 in the strikers 17, 18 are side-by-side on a level, and a heel 21a of the lever 21 engages both strikers as shown in Figs. 2 and 4. The strikers are then moved to the right together as described. On depressing the lever 21, the heel 21a comes opposite an undercut gap 22a in the striker 17 so that, when the heel 21 a moves to the right to the position of Fig. 3, the striker 18 alone is moved. This depression of the lever 21 is effected against the pull of a spring 24, Fig. 4. A locking plate 27 is adapted to be depressed along with the lever 21 to lock the strikers 17, 25 against movement. This plate 27 is integral with a plate 26 which slides vertically in fixed guides 30, Fig. 3, and is bent at 28 to form a trough in which a lug 29 on the lever 21 can slide. Lateral movement of the lug 29 in the trough is free, but vertical movement of the lug carries the plate. 26 with it.

Filed: 1918-10-28
Abstract: 134,287. Halliday, A. W., and MacIver, E. Oct. 28, 1918. Spark-extinguishers.-A spray of water regulated by the exhaust of a locomotive is delivered into the chimney. As shown in Fig. 1, the exhaust from the pipe 6 acts upon a baffle 4 which is connected by a lever 5, link 9, and lever 8 to the plug o of a stop cock 10 on a water-supply pipe 1 leading to a nozzle having a covering disk 2 forming a sprayer in the chimney 12. An adjustable spring 11 ensures steady movement of the plug. Alternatively, a cylinder 13 having an adjustable spring piston 14 may be mounted directly on the blast tube 6, and the piston connected by rods 17, 18 to the lever 8 of the plug. In the modification shown in Fig. 2, a piston valve is mounted upon the water-supply pipe to regulate the supply directly. The valve consists of a casing 23, Figs. 2 and 3, having bosses 29, 30 for connexion to the water pipes, and a piston 22 with an adjustable spring 24, and an annular recess 27 or a through hole 28. This valve is connected by a tube 26 with the exhaust pipe 6. Before use, a plug 31 on the tube 26 is opened to pass water into the tube till equilibrium of the piston is produced. The exhaust then acts to depress the valve to a greater or less extent and permit water to pass through the hole 28 or around the recess 27 to the annular perforated sprayer 21 or to an upwardly-turned open pipe. In a further modification, Fig. 5, the end 36 of the exhaust tube 6 is surrounded bv a nozzle 34 on the water-supply tube 1, and the exhaust acts upon a spring-loaded valve 35 mounted on that pipe to allow water to pass. The chimney may be extended into the smoke-box 31 and have a series of cone-shaped baffles 37.

Title: Improvements in or relating to direction-indicating apparatus for facilitating the navigation of craft
IPC: G01S1/02
Filed: 1942-12-15
Abstract: 579,167. Navigation systems for aircraft &c. TAPP, E. T. J., and RADIO ELECTRONICS, Ltd., (formerly VACUUMSCIENCE PRODUCTS, Ltd.). Dec. 15, 1942, No. 17842. [Classes 40 (iii) and 40 (v)] [Also in Group XI] A course for an aircraft &c. is marked by a narrow composite beam of light or infra - red rays having different parts of the beam differently modulated. As shown, three searchlights 11 produce overlapping beams, Fig. 2, the beams being modulated at different audio frequencies. The receiver on the craft comprises an electron-multiplier 8 with a photo-sensitive cathode, coupled to headphones 3. Single notes corresponding to one of the modulations will be heard in the outer areas 13 ... 15, two-note chords in the areas 16 ... 18, and a three-note chord in the central area 19 corresponding to the correct course. Alternatively, a central beam marking the course may be surrounded by a number of beams partly overlapping it and each other. An additional horizontal beam from a source 21 may indicate the height at which an aircraft should flatten out for landing. The arrange-, ment may be supplementary to a radio landing system of the overlapping-beam type provided with marker beacons 22, 23, the same headphones being used for all signals. The searchlights 11 may be mounted in a well 10 having a grating 12 or a pivoted cover-plate with a reflecting under surface, automatic means being provided in this case for closing the plate on the approach of aircraft wheels. Alternatively, the searchlights may be mounted above ground and may be automatically lowered into the ground if an aircraft approaches too near. Three searchlights 24 ... 26, Fig. 3, may be mounted in a triangular frame 33 rotatable vertically about a base 53 and horizontally about an axis 35, the angle of divergence of the composite beam being also adjustable by mounting the searchlights on links 40, 41 pivoted to the frame 33 and to a central plate 46 adjustable axially by a screw 47. The modulation of the beams may be effected by shutters of the kind described in Specification 573,900. In modifications, a single searchlight has three spaced shutters, Fig. 4 (not shown), or three coaxial shutters with annular shutter elements, Fig. 5 (not shown). On an aircraft carrier, the searchlight assembly may have a gyroscopic control to maintain the beam at a fixed angle to the horizontal.

Abstract: 1,101,795. Riveted joints; attaching tabs. E. C. FRAZE. 28 April, 1965, No. 17921/65. Headings B3A and B3U. [Also in Division B8] A method of joining two metal sheets, e.g. the tab (38) and tear strip (62) of an aluminium or steel closure (20, Fig. 8) comprises forming hollow rivets (24, 40, Fig. 6) on the sheets, one rivet fitting within the other, and squeezing the end walls (36, 42) of the rivets between dies (44, 45, Fig. 7) so as to extrude the walls (36, 42) radially outwards to head and interlock the rivets without compressing them axially. The walls (36, 42) are impact-extruded between convex end surfaces of the dies, the end radius of outer die (44) being less than that of the inner die (45) in order to produce more radial displacement in the outer wall (42) than the inner wall (36) and prevent interference. Alternatively, the end of the inner die may be flat. The tab and closure may be formed separately to produce the rivets, or placed together and pressed simultaneously between two sets of dies, the first (Fig. 2, not shown) producing a shallow dimple in the part or parts, and the second set (Fig. 4, not shown) causing inward radial flow of the dimple-material to thicken the rivet.walls. The rivets may be formed outwardly or inwardly of the closure, between a single set of dies (Figs. 12 and 15, not shown,) after which they are interlocked between further dies. The line of weakness defining the tear strip, is formed on the upper or lower surface of the closure (Figs. 10, 11, not shown).

Class 7(4) In ignition apparatus of the kind which includes a capacitance for effecting discharge across a sparking plug i, of the low tension type for example, there is provided a capacitor charging means, such as ignition coil a, b, a resistance g in series with the discharge circuit through the plug i, and a control gap h in parallel with the resistance, the necessary capacity being provided by the capacity of the coil a, b, and/or the associated conductor or by a separate condenser e connected in parallel with the coil a, b. A rectifier may be located between one end of the secondary winding b and the condenser whereupon the gap h is connected in parallel with the resistance and rectifier. The resistance may be directly connected to the plug i, but preferably a gap j is provided therebetween; an inductance may be inserted in the circuit to control the rate of discharge of the condenser e. An impulse from the coil energizes the sparking plug as well as the series gap j and upon the potential difference across the resistance g reaching a given value the gap h breaks down and permits discharge of condenser e afterwhich the residual energy of the coil recharges the condenser. In a modification, a distributer is provided and the series gap j may be comprised by the gaps between the various fixed electrodes and the rotor arm, but where a wipe distributer is used the gap is connected in series with the distributer. The induction coil may be replaced by a magneto, an alternating current source or an electrostatic machine.
