Filed: 1959-04-27
Abstract: 846,024. Stabilizing ships. MUIRHEAD & CO. Ltd. April 27, 1959, No. 14242/59. Class 113. In a ship stabilizer system the fins 10 are operated by a closed loop servo system, which may be electrical, hydraulic or any other suitable type, or the reset is proportional to the forces generated by the fins 10. In the embodiment described a signal from the sending means is applied to the synchro 41 to operate the pilot valve 45 via linkage 46 to cause an hydraulc amplifier to tilt the fin 10 via rocker arm 9 and shaft 11. The tilt causes a force c to be set up to oppose the force b, consequent to the fin tilt. The force c causes a slight deflection of the fin box 51 which is detected by the lever 25 and magnified by a multiple lever arrangement 53 which rotates the rotor of a resetting synchro 33 in a direction that re-aligns its field with that of Synchro 41 to close the pilot valve 45 and hold the fin 10 in position. The fin 10 may be retracted into the fin box 51.

Title: Improvements in or relating to steam-driven locomotives
IPC: B61C1/12
Filed: 1922-05-20
Abstract: 193,369. Aktiebolaget Ljungstr÷ms Angturbin. Feb. 18, 1922, [Convention date]. Cooling condensers, air blast for.-In locomotives having an auxiliary steam engine or turbine to actuate the fans or other members of an aircooled condenser, both main and auxiliary engines are connected to a common condenser, and more steam is supplied automatically to the auxiliary turbine upon increase of load on the larger turbine. Fig. 1 shows one arrangement in which the outlet from an auxiliary turbine. 12 passes directly to the air-cooled part 6 of the condenser, while the main turbine 9 exhausts into the water-accumulating chamber 7. Fig. 2 shows one arrangement for increasing the steam supply to the auxiliary turbine. The latter turbine 12 is fed by two steam nozzles 19, 25, of which the nozzle 19 is operating constantly under normal conditions. The main turbine is fed from a pipe 17 through a series of nozzles opened in succession by oil pressure in the pipes 20 - - 24. When the third nozzle comes into operation, the oil pressure also opens the nozale 25 through the valve 26. Fig. 3 shows a modified construction in which steam supplied to the larger turbine through the nozzle 32, drives, the part 33 as a direct-action turbine.. and the part 34 as a re-action turbine. The steam pressure in the pipe 36 rises with the load on the turbine and eventually raises the non-return valve 40 and supplements the steam supply to the smaller turbine 12.

Title: Improvements in or relating to electric lighters
IPC: F23Q2/28
Filed: 1963-04-10
Abstract: 1,041,032. Smokers' lighters. ROWENTA METALLWARENFABRIK G.m.b.H. April 10, 1963 [April 28, 1962; Oct. 13, 1962; Nov. 2, 1962 (2); Feb. 8, 1963], No. 14347/63. Heading F4F. [Also in Division H2] A lighter comprises a battery 1 of dry cells adapted to charge directly an electrolytic condenser 2 adapted to be discharged through the primary of a high tenson transformer, the secondary of which is connected to sparking electrodes 9, 10. The discharge circuit is controlled by a switch 3. Alternatively a two-way mechanical switch 4, Fig. 2 (not shown) or a two-way mercury switch 4, Fig. 4 (not shown) is arranged to connect the condenser either to the battery or to the transformer. Two interrupter switches may be included between the battery and the condenser, the first being opened by a plunger when the lighter is placed on a supporting surface, the second being operated by an actuating knob. A resistance 8 may be included between the battery and the condenser and the interrupter switch opened by the plunger is connected across the resistance 8. A mechanism for operating the fuel valve of a butane lighter and the electrical switches is shown in Fig. 5 and comprises a rotatably mounted pawl 13 and two actuating levers 7, 11. On pressing the first lever 7 inwardly against the action of a spring 17 the pawl 13 is rotated by a flat spring 14 until a lug 15 on the pawl engages in a recess 16 in the lever. A slide 19 secured to the first lever 7 has a sloped guide slot 22 engaging the stem of the fuel valve of the lighter and adapted to open the valve when the first lever is pressed inwardly. The end of the first lever 7 may actuate the switch 3 controlling the ignition circuit. The other lever 11 has a projection 27 which engages a further lug 28 on the pawl to rotate the pawl so that the first lug 15 is withdrawn from the recess 11 to allow the first lever to return to its initial position. The first lever can also be returned automatically, when the lighter is placed on a supporting surface, by a plunger 29, Fig. 7 (not shown), projecting from the base of the lighter and adapted to actuate a lever 30 adapted to engage a third lug on the pawl and to operate one of the interrupter switches. The sparking electrodes may be made of platinum or molybdenum and are preferably pointed; copper wires with platinum balls on the ends may be used. An electric switch, Fig. 11, comprises an actuating member 7 which is pushed down to disengage a counterspring 58 holding a spring arm 59 carrying a contact 44 in open position. The actuating member 7 also releases the spring arm from a spring-urged pawl 42. In a modification, Fig. 10 (not shown), the spring arm is replaced by a pivoted lever 43 acted on by a tension spring 51 and the counterspring is replaced by a lever 56 acted on by a compression spring 57.

Title: Improvements in or relating to looms
IPC: D03D47/00
Filed: 1966-04-01
Abstract: 1,084,430. Looms; starting. A. E. MOESSINGER. April 1, 1966 [April 9, 1965], No. 14504/66. Heading D1E. In the type of loom in which the shuttle is picked at a speed proportional to the speed of the loom and in which, prior to starting. the loom is at the part of its cycle immediately preceeding picking, the looms main shaft 5 is provided with a flywheel 12 connectable to the shaft 5 by a clutch 1, 2, 6 so arranged that, on starting, the flywheel's speed of rotation is in excess of its normal running speed. This ensures that the shuttle arrives at the far side of the loom at the correct moment in the cycle in spite of the acceleration from rest of the loom. The starting may be arranged over one or two picks. The clutch parts 1, 2 are motor driven and are free on the shaft 5. The clutch part 6 and a sun wheel 10 are splined to the shaft and the flywheel has an internal gear 11 engaging with planet wheels 9 mounted on the part 2 and in mesh with the sun wheel 10. When the loom is stationary a brake 13 is applied and the parts 1, 2 rotate freely on the shaft 5 causing the gears 9 to revolve around the stationary gear 10 and impart a high speed to the flywheel 12. Upon starting the parts 1, 2 are moved axially to the part 6 which then rotates the shaft 5 and sun wheel 10 thus causig a reduction in the speed of the flywheel. For starting over a two pick cycle a two speed motor and electrical circuit are described.

Title: Electron discharge device circuits
IPC: H01J21/18
Filed: 1942-10-16
Abstract: 563,113. Thermionic valves. STANDARD TELEPHONES & CABLES, Ltd. Oct. 16, 1942. No. 14509. Convention date, Oct. 23, 1941. [Classes 39 (i) and 40 (v)] An electron discharge tube of the type described in Specification 547,193 comprises a primary cathode 17, Fig. 5, control grid 18 and primary anode 19 having a small aperture 30 through which an electron beam can proceed towards an auxiliary electrode 20. A secondary emitting electrode 22 and collector grid 21 are disposed to the side of the direct path from the cathode 17 through the aperture 30. Electrode 20 need not repel the electrons as in the previous Specification, since this is performed by a variable magnetic field. This field may be parallel to the axis of the tube as shown, or, as shown in Fig. 8, may be perpendicular to that axis, preferably making an angle of 4 degrees with collector grid 21. The magnetic field in Fig. 8 may be in either direction. As in the previous Specification, a connection between the secondary emitting electrode 22 and the primary control grid 18 gives the tube a flipflop characteristic, the tube when switched on acting as an ordinary triode. In this case, however, the control is not by the grid 18 but by a variation of the magnetic field. Further increase of the field above the value necessary to deflect electrons on to electrode 22 may again switch the tube off. In a pulse counting circuit, a number of tubes 101-105, Fig. 10, are connected in a ring and the control coil for any one tube is partly made up by externally excited coil L1 and partly by the anode inductance L2 of the preceding tube ; control impulses applied to terminals 50 will only switch a tube on if the preceding tube is conducting. As soon as this occurs, the voltage impulse through a condenser C2 switches off the preceding tube. In the form shown in Fig. 5, a small anode current is necessary to keep the tube in operation and in order to obtain a completer cut off in the primary triode the arrangement shown in Fig. 12 may be adopted. Here the triode is divided into two parts, of different spacing, grid 18a co-operating with anode 19a to give a triode section with complete cut off, while grid 18b and anode 19b produce the switching effect. In an oscillation generator tuned anode coil 60, Fig. 13, acts also as the control coil for the tube. Thus, as soon as the tube becomes conducting, it is switched off again by coil 60 and oscillation is thereby sustained. The output voltage may be taken from coupling coil 80.

Abstract: 790,694. Making filter mouthpieces. MULLER, P. A. May 20, 1955 [April 5, 1955], No. 14548/55. Class 130. [Also in Group VIII] A web 1, Fig. 1, e.g. of paper, is passed through at least one pair of deforming rollers 6, 7 which crimp the paper in a longitudinal direction while stretching the web transverse to its length, the crimped web passing to a funnel 15 in which the web is folded into an endless filter rod. The paper web 1 is first crimped longitudinally by grooved rolls 6, 7, and then perforated along a number of transversely separated sections by perforating rollers 8. A fibre web 3, e.g. of cotton or cellulose fibres, is then laid on the crimped web 1 and the combined web is passed through rollers 10, which perforate the web in the spaces between the lines of perforations produced by the rollers 8, and through rollers 12 provided with knurled portions arranged in the spaces between the lines of perforations produced by the rollers 10. The funnel 15 has a passage 16 of decreasing width and increasing thickness leading to a cylindrical passage 17 provided with conveyer bands 25, 26 which facilitate the movement of the endless filter rod formed by the funnel 15 through the passage 17. Flutes 20, Fig. 3, may be provided at the entry portion of the passage 16 to produce a predetermined folding action on the web, which latter may be divided into narrow webs by knives on the roller 12. The endless filter rod is wrapped in a paper sheath by a wrapping machine 33. In modifications the deforming rollers 8, 10 or 12 have short spikes or obliquely toothed portions and the grooved roller 6 may be provided with differently shaped grooves. In addition more than one set of grooved rollers 6 may be provided, the grooves of successive rollers being nearer together to reduce the width of the web and driven at differing speeds to produce stretching of the web. The end of the roll 2, from which the web 1 is obtained and the beginning of the replacement roll are cut and overlapped as shown in Fig. 11 or 12 so as to avoid an increase in the amount of material at the junction point in the resulting filter rod. If the web 1 is of stiff paper, it may be rendered pliable prior to passing through the crimping rollers 6 by moistening it with atomized. water or steam, the web being dried after emerging from the rollers 8 by passing it over an electrically heated plate against which it is pressed by means of compressed air. The width of the web may also be reduced whilst it is in the pliable state by compressed air nozzles directed at the sides of the web.
