Title: Improved manufacture of tungsten powder by electrolysis
IPC: C25C5/04
Filed: 1924-12-18
Abstract: 236,152. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. June 27, 1924, [Convention date]. Drawings to Specification. Tungsten, obtaining.-Tungsten powder is deposited by electrolysis of a fused alkali-metal tungstate or a mixture of such tungstates. The temperature should preferably be above 900‹ C. and should also be considerably above the melting point of the electrolyte. Suitable electrolytes are lithium tungstate, or an eutectic mixture of lithium and potassium tungstates having a melting point of 500‹ C., or a mixture of sodium and potassium tungstates having a melting-point of 650‹ C. An excess of tungsten oxide may cause the precipitation of compounds known as " tungsten bronzes." To obviate this alkali oxides or hydroxides or substances producing them, but preferably peroxide, may be added to the bath. Too great an excess of alkali oxides causes re-solution of the tungsten. A suitable current density is 5 amps. per sq. cm. at 2.75 volts. The process may be carried out in a quartz crucible with tungsten electrodes. A regulating resistance is provided.

A retractible ship's log comprises a part 10 reciprocable through an opening in the ship's bottom 2 at will, or automatically so as to retract when the ship's speed falls below a predetermined amount, and a speeddetecting member 9 rotatable in a bearing in the part 10 in a horizontal plane and having a vane 12 so that it is aligned with the relative water flow. The member 9 may include a rotatable impeller, a Pitot tube, or a vane as described in Specification 823,684, the speed indication and relative angle of the member 9 (for driftangle indication) being transmitted through the parts 10 and 15 and thence by cable 18. A piston member 20 secured to 10 enables automatic retraction of the log at low speeds, its weight being such that it is normally retracted except when the " Pitot-tube " pressure from ducts 30 and 31 is sufficient to force it down to the position shown; in an alternative illustrated embodiment an hydraulic relay effects this. The bottom edge 50 of the vane 12 is inclined so that on striking an obstruction the log will be forced upwardly and retract quickly, especially at speeds only just above the critical speed. A sea-cock with passages 32, 33 can be rotated (when the log is in its uppermost position) through 90 degrees to connect ducts 30 and 31 sealing off the apparatus above it, and also equalize the pressure above and below the piston 20, to enable repairs and adjustment.

Title: Improvements in or relating to methods of signalling by means of modulated energy, for example wireless telephony
IPC: H03C5/00
Filed: 1929-10-10
Abstract: 340,060. Telefunken Ges. f³r Drahtlose Telegraphie. Oct. 31, 1928, [ConÀ vention date]. Systems for transmitting music.-In a method of improving tone colour and musical quality, e.g. in high-frequency telephony, the transmitter or receive has means for strengthening desired overtones, e.g. to compensate for previous weakening, or for inserting additional overtones. One or more fundamentals may be wholly or partly filtered out and used to provide the desired harmonics, or the sum and difference frequencies P + Q produced by modulating high-frequency currents may be influenced again by the modulating frequencies so as to produce frequencies P + 2Q, the process being repeated if desired. In the arrangement shown in Fig. 1, modulating frequencies Q in the circuit lm and high-frequency current P in the circuit V are supplied to modulating valves a1, the anode circuits of which are differentially connected. Frequencies P + Q are led to the aerial circuit and through transformers d1 to the input coil s1 of a second pair of modulating valves a2, thus producing frequencies P + 2Q. The process is repeated in the valves a3. The couplings k1, k2, k3 may be varied or omitted, so that the aerial currents may represent any desired combination of overtones. Fig. 2 shows how two melodies A, B may be simultaneously rendered ruder control of a conductor who can vary the couplings k1 - - k<1>3 to determine the quality of each melody. The arrangement shown in Fig. 2 may be used at a receiving station, the circuits A, B being connected to different receivers, and the aerial circuit being replaced by a common distributing circuit. The overtones reinforced may correspond to those of the major triad; the intensity of the various overtones may be controlled by influencing the circuits in question inductively or capacitatively, e.g. by the hand of a conductor.

Title: Control of vehicle transmissions

Filed: 1972-07-04
Abstract: 1421329 Change-speed control GREATER MANCHESTER PASSENGER TRANSPORT EXECUTIVE and G P B MARTIN 2 Oct 1973 [4 July 1972] 31130/72 Heading F2D In a multi-ratio gear-box for a vehicle, particularly an epicyclic gear-box in combination with a fluid flywheel, shock due to the arresting of gear trains as a starting gear is engaged is minimized by the provision of means whereby a high ratio, e.g. third or fourth gear in a four-speed gear-box, is automatically engaged for a limited period before the starting gear is engaged. In an electro-pneumatic selector system for an omnibus in which the gear selector (not shown) also controls passenger doors, fourth gear is temporarily engaged when the selector is moved from the " doors open" position to neutral. When the " doors open " position is selected a switch S D  is closed energizing a solenoid L D  which controls an air valve for the doors and completing a circuit through a diode D, the winding of a relay M and a resistor R, at the same time charging a capacitor C. Movement of the selector to neutral opens the switch S D  so that the doors close and closes a switch S N  which causes a neutral indicator lamp N to be lit and completes a circuit through the relay M and solenoid L, controlling a pneumatic motor to engage fourth gear for a limited period determined by discharge of the capacitor through the relay winding. Selection of a starting gear before completion of the discharge of the capacitor results in disengagement of fourth gear. In a modification, discharge of the capacitor triggers a transistorized circuit controlling the relay. Instead of the timer constituted by the RC combination the circuit may employ a switch actuated as the doors close so that the period during which fourth gear is engaged is determined by the duration of the door closing operation. In installations in which the gear selector has no " doors open " position and the doors are openable by a separate control only when neutral is selected and are closed either by a door-closing button or by selection of any gear, the engagement of the high gear may be responsive to movement of the selector from neutral, and its disengagement, followed by engagement of a starting gear, controlled by a switch actuated as the doors close. Alternative means for temporarily engaging a high gear before starting may include a sensor to detect when the gearbox output shaft is stationary.

Abstract: 363,045. Switchgear structures BROOKHIRST SWITCHGEAR, Ltd., Northgate Works, and LANCELEY, C., 12, Lime Grove, Hoole, both in Chester. Oct. 18, 1930, No. 31249. [Class 38 (v).] Snap-action switches; hand. actuating devices.-Interlocking means [between an isolating switch and the casing of associated switchgear is such, that before a handle-key can be removed from the isolating switch which it operates, it is necessary to lock the switch in its open position, and the same handle-key is used for locking the casing of the switchgear from which it cannot be withdrawn until the casing is closed and locked. To close the isolating switch A, Fig. 1, a handle-key K is inserted in a stem C and rotated through 90‹ to release a locking pin F, the pallet k1 moving first along an axial slot c1, and then along a circumferential slot c2 of the stem C, Fig. 11, and at the same time along an axial slot d1, and a circumferential slot d2 of a bush D, Fig. 13, in a boss on the isolating switch. The bush D has a second axial slot d3 so that the handle-key coupled with the stem C may be moved to close the isolating switch contacts a5 with a snap action ensured by springs a2, rollers a3 and cam plates a4. The handle-key K cannot now be removed until the switch is reopened, and the locking pin F again engaged. The switchgear casing is fitted with a lock comprising a rotatable quadrant t1, Figs. 15 and 16, which engages a fixed stop S. When the handle-key has been removed from the isolating switch it may be inserted in this lock, and turned to release the quadrant t1 allowing the door H to be opened. Immediately the door is opened a fixed pin R ceases to restrain a locking piece P which moves axially on a bolt m4 under the action of a spring p1, Fig. 19, to engage an abutment t2 on the quadrant t1, to prevent the latter from being turned while the door is open. The handle-key K cannot be removed from the casing lock until the quadrant is turned into its locked position because the pallet k1 engages behind the fixed casing m2 of the switchgear.
