Title: Operating circuits for electric discharge lamps
Inventor: BIRD LESTER T
IPC: H05B41/231
Filed: 1957-12-20
Abstract: 814,936. Supply systems for space discharge lamps. ENGELHARD INDUSTRIES Inc. Dec. 20, 1957, No. 39659/57. Class 38 (4). A high-pressure gaseous discharge lamp 9 is started by connecting it across the series-connected primary and secondary windings 3, 5 of a transformer 4 and injecting into the circuit, by way of a winding 10, a starting pulse produced by the elements 18, 19, 20, 21, the lamp during normal operation being connected across the secondary winding 5 only. The changeover in the connections is accomplished by means of relays 17, 15, the relay 17 being of the time-delay type. Thus on switching on, the lamp is started on a high voltage by an injected pulse when the spark gap 19 breaks down and after a time delay the contact 16 of relay 17 closes to energize relay 15 whereby the relay 15 operates first to close contact 111 and then to open contact 13 when the lamp 9 is then connected across winding 5 only and operating on a low voltage. In another embodiment the relays 15, 17 are omitted in which case the contacts 11, 13 are operated manually.

Any OH or NH2 group in the acid is protected prior to conversion of the acid to its halide (effected by the action of a halogenating agent, e.g. SOCl2) and is regenerated in the course of the reduction.  The aldehydes may be converted to their dialkyl acetals by reaction with an alkanol in the presence of an acid catalyst.  Pharmaceutical compositions, having anti-inflammatory action, contain the novel aldehydes and acetals as active ingredients.

Abstract: 1442826 Discharge devices for gas containers CBF SYSTEMS Inc 22 Aug 1973 39854/73 Heading F4P A discharge device for a gas cylinder 38 comprises a housing 10 with an entrance port 12 communicating with the neck of container 38 and an exit port 11, a frangible plug 36 being inserted in port 12 and having a closure disc 34 which normally closes port 12 from a longitudinal bore 13 in housing 10. A valve member is located in the bore 13 and has a piston 14 and a shear tool 33 with a cavity 35 which receives disc 34 such that, if the valve member is moved rightwards, the tool 33 will remove disc 34 from plug 36 and a cylindrical bore 32 in the valve member will come into alignment with ports 11 and 12 to permit flow of gas from container 38. Actuation can be automatic or manual. An explosive cartridge 16 in a threaded end plug 15 can be exploded by current in conductors 17, thus forcing piston 14, and hence shear tool 33, to the right to perform the opening function. A nut 22 is threaded on to an extension 21 of cylinder head 18. A compression spring 26 is located in an annular slot in nut 22 and bears against a washer 27 which is urged against a ring 28 on a pin 25 integral with the valve member and slidable in bore 23 in head 18. If the nut is unscrewed, it urges shear tool to the right to break the disc and then the spring 26 urges the valve member further to the right to align opening 32 with ports 11, 12. During manual actuation air can be drawn from the atmosphere via check valve 20 and bore 31 in the space between piston 14 and end plug 15. A filling valve 40 is provided for container 38. An embodiment, in which the manual operating means in modified, is also described (Fig. 5, not shown).

The cathode connection is from a bus-bar 12 to spaced steel beams 9 which extend across the cell floor, and the anode connection is from a bus-bar 11 and connections 16, 28. The cover 17 may be secured to the trough wall by bolted strips 24, or by pressure feet connected by bars to the frame 15, or by pressure members pivotally attached to rods carried by the frame 15. The invention is applicable to diaphragm cells and to fused-electrolyte cells. U.S.A. Specification 2,370,087 is referred to.

[Also in Division C7] Resistive films are formed of #-tungsten by vaporizing tungsten source in a low-pressure oxygen-containing atmosphere, the vaporized tungsten being deposited on a non-conducting substrate pre-heated to at least 25 C., the relationship between the oxygen pressure and the distance between the source and the substrate being such that collisions occur between vaporized tungsten molecules and oxygen molecules before the tungsten molecules are deposited on the substrate. The arithmetical product of this pressure and distance should be at least 5 x 10<SP>-3</SP> Torr cm. and preferably between 3À5 x 10<SP>-3</SP> and 1 x 10<SP>-2</SP> Torr cm. The film may be cooled off in an oxygen bearing atmosphere at 5 x 10<SP>-5</SP> Torr or less and may subsequently be baked. Pressure and substrate temperature are automatically controlled (see Division C7). Fig. 3 shows a #-tungsten film 50 on a glass substrate 51 in a potentiometer, the sliding carbon contact 53 being spring pressed.

Abstract: 1324817 Boiler penthouse FOSTER WHEELER CORP 21 Aug 1970 [28 Aug 1969] 40400/70 Heading F4A A boiler penthouse 10, which forms an enclosure on top of boiler 12 to reduce heat losses from pipework etc., projecting from the boiler, is pressurized to prevent corrosive gases entering from the boiler should leaks occur. The considerable stress created because the boiler gets hotter and therefore expands more than the penthouse are reduced by the insertion of a U-shaped channel 24 in plate 34, 36 joining the penthouse to the boiler casing 16. To prevent failure of the join between the penthouse and the boiler casing 16 at the corners 38 where the stress is maximum, corrugations 44, 46, 48 running round the corner are made in plate 36 thereby allowing  the corner region to be compressed diagonally outwards. Additional corrugations 66 at the corners of the U-shaped channel 42 and 50, 52 perpendicular to the boiler walls may be provided.

Patent GB-944613-A (GB)
Title: Improvements in electrolytic machining apparatus
IPC: B23H3/02
Filed: 1960-11-25
Abstract: In an electrolytic machining apparatus, a control system is effective to stop relative movement between an electrode and a workpiece and to cut-off the D.C. supply to the electrode and workpiece in response to minor transient changes in the D.C. supply due to short circuiting between the electrode and workpiece, the control system being substantially insensitive to a gradual change in, or steady state conditions of, the D.C. supply. In the arrangement shown, the control grid of a gas-filled valve 2D21 is normally biased so that the valve is non-conducting.  This control grid is connected through a high-pass filter C3, C2, L1, a potentiometer R1, a capacitor C1 and conductors 63 to the electrode and workpiece. Under transient conditions due to a spark between the electrode and workpiece, a signal is applied to the control grid causing the valve to conduct. A relay RY6 is now energized and closes its contacts A to cause the energizing of a relay RY5, a signal lamp S and a thermal delay relay TDR.  The relay RY5 closes contacts E to complete a holding circuit for itself, opens contacts B to cut-off the supply to the relay RY6 and the valve, and closes contacts C <PICT:0944613/C3/1> and D to cause the stopping of the movement between the electrode and workpiece, e.g. by causing the de-energizing of a drive motor (not shown) and to cause the interruption of the D.C. supply to the electrode and workpiece. After a short delay, the relay TDR opens its contacts F to interrupt the holding circuit for the relay RY5 so that the control system automatically returns to normal and permits the manual operation of a conventional starting system (not shown) to re-start the apparatus after the fault condition has been removed. The control system described also functions when the D.C. supply to the electrode and workpiece fails, to prevent mechanical damage to the electrode.
