Title: Electric arc torch
Inventor: BROWNING JAMES ALEXANDER
IPC: H05H1/42
Filed: 1964-05-12
Abstract: 1,015,540. Cutting by fusion. THERMAL DYNAMICS CORPORATION. May 12, 1964, No. 19692/64. Heading B3V. [Also in Division H5H] In a plasma arc torch the gas is arranged to flow both away from and towards the cathode. As shown, the gas is injected into the arc with a swirling motion at ceramic ring 12 and some flows over the cathode 14 to prevent erosion products contaminating the working jet 17. A similar arrangement is illustrated in Fig. 2 (not shown) wherein work to be cut constitutes the cathode. Another arrangement (Fig. 4, not shown) produces two useful plasma jets in opposite directions, or the electrodes may be bent to combine both jets into one; this arrangement operates on A.C. The device is also illustrated (Fig. 5, not shown) producing a supersonic jet stream in a vacuum chamber, with an opposite, wasted, low-pressure jet at the cathode.

Title: Film feed and shutter cocking
IPC: G03B17/42
Filed: 1976-05-13
Abstract: 1536915 Shutter cocking and film feed mechanism BALDA-WERKE PHOTOGRAPHISCHE GERATE UND KUNSTSTOFF GmbH & CO KG 13 May 1976 [28 Nov 1975] 19701/76 Heading G2A In a camera mechanism for shutter cocking and film feed a single differential drive is provided for carrying out the two operations in succession. The mechanism is as shown generally in Fig. 1, which shows the position after shutter cocking and film feed has been completed and the camera is ready to effect an exposure. The drive is actuated by a ring 1, which drives, via planet wheels 4, 5, 6 and a sun wheel 8, a shaft 9 and a satellite carrier 7. The shaft 9 drives a spool 14 carrying the film 15, and the carrier 7 is coupled to mechanism for cocking the shutter. Carrier 7 has radial lugs 18 which can engage an arm 19 of the shutter cocking lever 20, this being biased clockwise by a spring 22'. On turning ring 1, carrier 7 is rotated clockwise causing anti-clockwise rotation of cocking lever 20 against spring 22', so cocking the shutter. This is now the position of Fig. 3. During this time the film feed has been locked against movement by a pawl 46, which has a tongue 48 in locking engagement with a ratchet wheel 10 on the shaft 9. At the end of the cocking movement of lever 20 it is locked in this state and pawl 48 is pivoted so as to disengage from ratchet wheel 10. Carrier 7 is also locked with lever 20, so that further rotation of the actuator ring 1 now drives shaft 9 and hence spool 14 to wind on film 15. A film stop arm 58 has an end 61 which can align with perforations 16 in the film. During the locking movement a tongue 56 of a cam lever 52 engages the other end 57 of arm 58 and pinches it against the action of a spring 60 so that the end 61 bears against the film. When it becomes aligned with a perforation it enters therein, and is carried along so that end 57 disengages from tongue 56, so that the cam lever 52 pivots to disengage from pawl 46, which is now spring-urged into locking engagement with ratchet wheel 10. Thus the entering of the end 61 of arm 58 into perforation 16 terminates the film wind. When the mechanism is in the "ready" position of Fig. 1 the shutter release is actuated by pivoting lever 32 in the direction of the arrow. This releases the shutter cocking lever 20 to rotate clockwise, during which movement a lug 23 on lever 20 actuates the shutter to effect the exposure.

Title: Apparatus for producing angular-velocity modulation in a cathode-ray beam
IPC: H03C3/30
Filed: 1945-08-02
Abstract: 604,303. Frequency modulation. LONGO, G. Aug. 2, 1945, No. 19912. Convention date, March 8. [Class 40 (v)] [Also in Group XL (a)] A very high-frequency signal is subjected to a variable phase-shift by applying it to electrode A to modulate an electron beam which is then caused to pass from cathode K and anodes B, D, through a long drift tube E, the potential of which, and hence the time taken to reach collector P, is controlled by the variable parameter. The device may be within a magnetic screen; or longitudinal magnetic focusing may be used. Two devices may be used in series, the output current of the first device being applied to grid A of the second device. To produce frequency modulation, two electron beam devices are used in the circuit of Fig. 2. The very high-frequency f and a frequency of half the carrier frequency F are mixed in a device H which applies separate outputs of f + ¢F and f - ¢F respectively to the devices T, T<1> which are identical except that their drift lengths are in inverse ratio to the applied frequencies. The intelligence signal u is applied with opposite sign to two valves Q, Q<1>, which work into a common periodic circuit LC and supply to E<1> electrodes E, El signals of opposite sign proportional to the differential coefficient of u. The outputs of the two tubes have frequencies f + ¢F + #F and f - ¢F- #F respectively, where #F is the frequency shift corresponding to the phase-shift introduced in the drift tubes. These are mixed in a device S which gives an output F+2#F. The Specification as open to inspection under Sect. 91 comprises also a mathematical discussion in which the value of #F is deduced; it is shown that, for the same distortion, the present device is 50 times as sensitive as the known circuit using two voltages in quadrature, one of which is varied in amplitude. To reduce amplitude modulation due to space charge debunching in the drift space, the beam current is kept very low. In modifications, an intermediate frequency is interposed between f and F; or two adjacent harmonics of F are used to give outputs f+pF, f+(p-1)F. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to luminescent screens
IPC: H01J29/18
Filed: 1952-08-14
Abstract: 738,285. Luminescent screens. GENERAL ELECTRIC CO. Aug. 14, 1952 [Aug. 23, 1951], No. 20474/52. Drawings to Specification. Class 39 (1). A luminescent screen which has sufficient conductivity to prevent accumulation of charges comprises a transparent glass support, having a transparent coating of titanium dioxide and an overlying coating of luminescent material comprising Zn and/or Cd combined with S and/or Se, and is made by depositing the titanium dioxide on a glass plate heated to 150-200 C., and then depositing the phosphor with the plate at 500-600‹ C.; an activator such as MnCl 2  is deposited at the same time as the phosphor. The screen is preferably excited by cathode rays. In the particular method described titanium chloride vapour and water vapour are supplied to a chamber containing the glass plate and interact to form Ti0 2  which then deposits on the plate to a thickness of about one-tenth of a micron. The coated plate is then removed to a second chamber. Hence an electrically-heated refractory pot produces Zn or ZnCl 2  vapour, and MnCl 2  vapour is also produced at the same time. H 2 S is introduced to produce ZnS which then deposits on the plate. It is stated that the above process results in the reduction of the resistivity of the Ti0 2  from several thousand megohms per square to 4000 ohms per square or less due to migration of Zn and/or S atoms into the Ti0 2 . The ZnS may be replaced by CdS or ZnCdS.

In a conveyer system in which trolleys are propelled along a track by pusher dogs carried by an endless chain travelling along a track vertically disposed above the load-carrying trolley a load-carrying trolley comprises an abutment member capable of projecting into or out of the operative position in the path of the pusher dogs and an actuating element longitudinally slidably mounted on the trolley and projecting from one end thereof and having a laterally projecting peg which engages in a plate associated with or forming part of the abutment member and the arrangement is such that inward movement of the actuating element will result in the peg being moved along the slot to move the abutment member to its retracted position. In the arrangement shown the load-carrying trolley 11 is driven along a track 10 by pusher dogs 16 or 17 engaging an abutment 21 and propelled.by an endless chain 15 supported on wheels running on a track 12. The abutment 21 includes a plate portion 22 disposed in a plane parallel to the longitudinal axis of the trolley 11 and provided with an inclined slot 23 engaged by a peg 27 carried by a rod 26 of a buffer 24 horizontally slidably mounted on the trolley. The abutment is normally held in the projected position by a compression spring 31 but when the buffer 24 meets an obstruction the rod 26 is moved inwards to retract the abutment as the peg 27 moves along the slot 23. Another buffer 25 may be provided at the other end of the trolley and connected to the peg 27 by a cranked rod 28 and a pivoted lever 29. As an alternative to the cranked rod 28 a rod similar to the rod 26 may be provided with a peg 27 which pegs 27 engage inclined slots in an inverted V slot in the portion 22. The buffers 24 or 25 may be provided with lateral projections extending beyond the trolley sides in order to engage movable abutments to operate the buffers 24 or 25 and hence the abutment 21 at predetermined points along the track. In an alternative arrangement the trolleys are supported on driven endless parallel chains and the trolleys incorporate rollers which engage plates or running surfaces carried by the chains or alternatively the chains may incorporate rollers which engage running surfaces on the trolley underside. In this case each trolley is provided with a retractable driving abutment as before.
