Title: Improvements in the transmission of motor vehicles
IPC: F16D41/08
Filed: 1926-11-11
Abstract: 290,310. Wardman, C. B. Nov. 11, 1926. Facilitating changing speed. - To facilitate changing speed upon a vehicle there is arranged between the gear-box and the road wheels a oneway clutch which is adapted to be locked bv a positive clutch with synchronizing frictional parts. Upon the end of the driven shaft 39 projecting from the gear-box is secured the inner member 5 of the free-wheel clutch, and between this and the gear-box there is feathered the movable member 43 of the claw clutch. The outer member 6 of the free-wheel clutch is integral with the tail shaft 40, and between this and the member 5 are the usual grip rollers 7. The member 6 has clutch teeth 41 on its end face above which is yieldingly held an annular friction clutch member.49. The free-wheel clutch isolates the gearbox in changing speed and allows coasting. When it is desired to lock it, the member 43 is advanced towards it by a lever 26. A frictional face 48 upon the member 43 strikes the annulus 49 so that the teeth of the member 43 and the teeth 41 are brought to nearly the same speed before coming into locking engagement.

Abstract: 1299698 Antiskid braking systems SOC ANON DBA 17 June 1971 [23 June 1970] 28542/71 Heading F2F An antiskid braking system includes a device for modifying the rate of braking pressure rise to avoid too high a rise initially which may produce wheel lock in even good conditions, the device comprising a normally open solenoidoperated valve EV2, connected across a pressure restricting element J, and an electronic system SE responsive to signals representative of vehicle wheel speed developing a signal fed to a solenoid operated valve EV1 to close the latter and isolate the brake F when a skid is imminent, the signal also closing valve EV2. The signal is a pulse produced in response to a threshold voltage, tapped on a potentiometer Rh, as a result of a predetermined deceleration. Pressure is released from the brake by a valve EV3.

Abstract: 483,575. Electron multipliers. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and BANKS. G. B. Oct. 21, 1936. No. 28659. [Class 39 (i)] An electron multiplier has a source of electrons, a collecting electrode, and a plurality of grid-like or perforated secondary emissive electrodes interposed in succession in and extending across the space between the source and the collector and means for generating a magnetic field having lines of forces running in the direction of length between the source and the collector, the grids being parallel and canted so as to make angles other than right-angles with the lines of force, the arrangement being such that the secondary emissive electrodes are struck obliquely by electrons. In a modification, the grids 4 ... 9, Fig. 2, are nested cones, and the collector 3 is similarly conical. If the source is thermionic, instead of photo-electric, control and space charge grids may be associated with it. A potentiometer supplying the voltages for the secondary emissive electrodes may be housed in the envelope.

Title: Improvements in or relating to gaseous discharge devices
IPC: H01J3/02
Filed: 1926-11-15
Abstract: 263,111. Raytheon Manufacturing Co., (Assignees of Smith, C. G.). Dec. 21, 1925, [Convention date]. Vacuum tubes. - In a gas-filled tube for use as a rectifier, amplifier, oscillator, converter, &c., the vapour of an alkaline-earth metal, which is confined to the region of the discharge, is produced from a source maintained at such a temperature that only a vapour pressure of about 10-<5> mm. of mercury or less is developed. The gas may be argon or neon, at a pressure of 2 cm., or mercury vapour, and may assist in retaining the alkaline-earth metal vapour within the cathode space. In one construction, a tubular electron emitter C, Fig. 1, is heated by an internal filament H, and projects into an enclosure K having a narrow outlet S at the top and an elongated appendix at the bottom containing calcium M or an alloy thereof. A band R conveys heat from the electron emitter C to the appendix. Anodes A', A<2> are arranged near the outlet S. The tube contains a drop of mercury Hg. In operation, the cathode enclosure K, which is connected in series with the filament H. to a third winding of the supply transformer, may be heated to 1000‹ C. by the electron emitter and the discharge, while the calcium &c. M is at 500‹ C. An electric pumping action retains calcium vapour within the enclosure. In another construction, the cathode is a tungsten or nickel rod projecting into an enclosure having a narrow outlet, opposite an anode, and a depending pocket containing calcium etc.; at starting the enclosure is heated by a discharge between it and the cathode rod, the current being alternating and the supply means such that the voltage, initially about 110, falls rapidly with increasing current. In a third construction, a cylindrical hollow anode, with a pocket for calcium &c., contains an axial cathode filament, the leads of which carry disc baffles obstructing the escape of vapour along them. In this case a magnet external to the tube produces along the axis of the anode a field having a component alternating in synchronwith the voltage of the tube, which is thus caused to act as a rectifier. The gas pressure may be 10-<3> mm. of mercury. Fig. 4 shows an audion in which a cup-shaped anode J serves as vapour enclosure. its lower end having a cover with tubular apertures for the filament and grid conductors. Disc baffles may be fitted below the apertures. Calcium N is vaporized mainly by radiation from the filament B. In a fifth construction, a T-shaped tubular cathode enclosure has its vertical limb closed to contain the calcium &c., and a filament passes through the horizontal member of the enclosure, on either side of which anode plates are arranged. The filament, if of tungsten, may be heated to 1300‹ C., and either it or the enclosure may form the cathode. A drop of mercury may be included in the container. Specifications 170,015, 230,026, 246,036, 248,721, 248,722, 263,108, 263,109, and 263,110 are referred to.

[Also in Divisions G1 and H4] In a sonic flaw-testing system for plates utilizing Chladnic sound patterns produced by oscillation generators (see Division H4), the plates are transported to and from the testing position as follows. Trolley 5 runs on rails A, C and supports rigid hooks 6; trolley 8 runs on rails B, C and supports rigid hook 7. Centering plates in groups 2a, 2b are provided between rollers of a roller track, in order to bring a test plate E into line with the longitudinal axis of the roller track; the centering plates are slidably guided in the bed of the roller track and are driven simultaneously by rack-andpinion gearing. A stop 1 is provided for arresting the test plate. Hydraulically or electrically driven rams 3 lift the test plate into the testing position. A transversely movable oscillation generator 9, which can be moved downwardly against the rear edge of the test plate, is provided on trolley 8; and a second oscillation generator 11 is provided on a transversely movable slide 10. In operation, whilst plate E is rolled forward from the left, stop 1 is raised to bring the test plate to rest; the position of the plate relative to the longitudinal axis of the roller track is then corrected by centering plates 2a, 2b which subsequently return to their original positions. After this, lifting rams 3 raise the test plate, Figs. 9 and 12, trolleys 5, 8 bring their respective hooks forward from the left, the lifting rams are lowered and the hooks support the plate which is then tested. The plate is returned to the roller track by raising the lifting rams and at the same time moving the oscillation generators vertically away from the plate, returning the trolleys to their starting positions at the left-hand end of the rails A, B, C, and lowering the lifting rams and stop 1; finally, the roller track is set in motion to effect further transport of the plate and the conveyance of the next plate to be tested. In a modification the centering plates are replaced by an arrangement in which the rail B is omitted and tiltable rails are utilized.
