Abstract: 627,287. Magnetrons. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 20, 1945, No. 21286. Convention date, May 30, 1942. [Class 39 (i)] An anode for a magnetron comprises a tubular laminated cylinder built up from a plurality of thin sheet metal plates 4 which are first plated with a fusible metal, stacked with their openings in register and then consolidated by brazing or other heating processes. The opening or hole in each lamina comprises a central circular aperture with slots extending outwards. These slots may be of a variety of shapes, e.g. straight-sided radial with or without rounded ends, tapered and radial or slotted tangentially, as in Fig. 11, so as to give the desired anode configuration. The ends of the anode are sealed by sheet metal cups 8 attached by brazed metal collars, and the cups themselves are closed by flanged metal headers 10 hermetically sealed by welding. The indirectly heated cathode 1 is supported on a bridge 12 which consists of metal strips 14, 15, 16 joined by two loops of cane glass 17. An expansion fold 18 accommodates movement due to cathode heating. A heat shield 20 and a disc 19 are mounted coaxially on the sleeve of the cathode. The discs may project at places 4a to provide cooling fins and plated washers may space the discs longitudinally. The Specification as open to inspection under Sect. 91 also comprises the stacking of plates with different configurations, e.g. wide and narrow teeth to give the desired cavity shape. Staggering of the openings produces curved or spiral cavities. The cavity may also be given a conical shape. Some of the interleaved discs may be of magnetic material to distort or shape the magnetic field. One modification, Fig. 19 (Cancelled), shows cathode/grid assemblies 29, 30 mounted in separate cavities 31. This subject-matter does not appear in the Specification as accepted.

Abstract: 1396614 Photo-electric navigational aid; route progress indicators J F EDWARDS 4 May 1973 [10 May 1972] 21785/72 Headings G1A and G1K A navigational aid apparatus for a driver of a motor vehicle comprises a nine-bit scaling counter ICX, IC12, IC2-8 which receives input pulses produced by photo-cell P1, apertured wheel 11  connected to the vehicle speedometer cable, and lamp LP1, the counter supplying output pulses representing one tenth of a mile travelled to the input of a further counter IC17-23 forming a distance register which resets at every 128th input pulse and which is provided with means to enable the further counter to be set selectively to the complement from 128 of a required number of pulses. Thus a tape recorded speech signal to be broadcast to the driver after one mile travelled is initiated by receipt of 118 2KHz pulses recorded on another channel of the tape in the further counter plus ten pulses from the output of the scaling counter. The scaling counter is inhibited (at the 1 and 13 pins of ICX) while the complementary number of pulses is loaded into the distance register. When the distance register reaches zero the tape motor is started by IC11 and the speech is broadcast. A calibrate button when pushed earths pins 9 of the distance register ICs and sets the register to 127 leaving 1/10mile to go before the next instruction. Therefore the previous verbal instruction would have told the driver to calibrate at a given landmark en-route. (For Figures see next page)

Title: Purification process
Inventor: CHUFFART ROBERT CHARLES
IPC: B01D11/02
Filed: 1955-07-28
Abstract: Crystalline organic compounds which are insoluble in, and chemically inert to, water, are purified by removing mother liquor from the crystal surfaces by treatment with an aqueous medium containing an emulsifying agent.  The crystals may be obtained by cooling a supersaturated solution so that only one solid product is obtained and the bulk of the mother liquor is removed at the same temperature, the crystals then being treated with the aqueous medium containing the emulsifying agent at a temperature at least as high as the crystallization temperature.  The crystals may be treated by agitation and, if desired, comminution.  In examples para-dichlorobenzene crystals concontaminated with ortho - dichlorobenzene are treated with water containing sodium dodecylbenzene sulphonate, and with water containing an emulsifying agent made by condensing cetyl alcohol with ethylene oxide; and 1,2,4,5-tetrachlorobenzene crystals contaminated with other chlorobenzenes is treated with water containing an emulsifying agent made by condensing octylated cresols with ethylene oxide.  Other compounds which may be treated are mentioned.
