Patent GB-679624-A (GB)
Title: Process and device for the manufacture of plastic masses
IPC: C08J3/20
Filed: 1949-05-20
Abstract: Plasticized thermoplastic synthetic resin powders, e.g polyvinyl chloride and copolymers of vinyl chloride and ethyl acrylate or plasticized cellulose derivative powders, e.g. acetone-soluble acetylated cellulose, are made by mixing the powdered resin, in the absence of pressure, with a plasticizer and stirring and heating the mixture by radiant heat, e.g. red, infra-red or black ray heaters, until the individual powder grains become gelatinized and a sample on cooling to room temperature feels dry and is a free-flowing powder. The radiant heat is preferably applied directly to the mixture, e.g. from the cover of the mixing apparatus (see Group II).  The temperature of the mixture is generally maintained below the softening point of the resin, but if desired the temperature may equal or exceed the softening point of the resin by a few degrees for a short time. After the start of gelatinization, fillers, e.g. slate powder, kieselguhr, pigments or dyes may be added to the mixture. Specified plasticizers are di-(2-ethyl-hexyl) phthalate, tricresyl phosphate, dioctyl phthalate, and dibutyl phthalate.  The powders can be further treated in die-casting processes, spiral presses and wire-squirting machines, used for coating wood, fabric, paper or metal, or made into sheets, slabs, strings, tubes or cable coverings.ALSO:A mixer comprises a rotating container for the substances to be mixed, one or more mixing arms extending into the container and moving vertically with respect to the rotating axis of the container and a cover for the container provided with a slot for the arms and carrying a heat-radiating device such as a red, infra-red or black ray apparatus.

Title: Logarithmic periodical antenna array
IPC: H01Q5/15
Filed: 1973-03-21
Abstract: 1414870 Aerials ALLGON ANTENN AB 21 March 1973 [29 March 1972] 13621/73 Heading H4A In a log-periodic dipole array, each dipole comprises four collinear radiating elements with feeding arrangements such that they may function either as a half-wave resonator having a single current antinode (in a lower frequency range), or as a full wave resonator having two current antinodes (in a higher frequency range). As described, a log-periodic aerial array comprises a plurality of parallel dipoles which are mounted on a boom 5 of rectangular crosssection containing feeders 11, 12. Each of the two arms of a dipole has a central member 1, which is surrounded by two collinear tubes 2, 3, between which there is a gap 4. The inner tube 2 is welded or is otherwise secured at its circumference to the boom 5, and extends along the member 1 without contacting it. At the gap 4 between the two tubes, the outer tube 3 is mounted on the member 1 by an annular spacer 10 secured to the inner periphery of the tube. Two outer metal members 8, 9 extend from the gap 4 over the tube 3, and partially surround it (as is shown in Fig. 2). Two outer metal members 6, 7 similarly extend from the gap 4 of the tube 2, and partially surround it. The central members of the dipole arms are connected to respective ones of the feeders 11, 12 and are supported in the boom 5 by insulating discs 15. In operation, considering feeder 11 for example, feed takes place as shown by the arrow 13. At a first and lower frequency a current distribution I 1  will apply, the dipole functioning in the half-wavelength mode, with a current maximum at the boom 5. At a second and higher frequency the outer members 6 to 9 of the tubes 2, 3 will carry currents (as shown by the arrow 14) and the dipole will have a current distribution I 2 , functioning as two inphase collinear half-wave dipoles. The frequency range of the aerial is thereby divided into two portions, and each part of the array is used in both. In a second embodiment, the central members 1 are tubular, and the outer members 8, 9 of the tube 3 are omitted (Fig. 3, not shown). In a third embodiment the outer members 6, 7 of the tube 2 are replaced by wires which are connected via insulators to supports extending from the boom 5 (Fig. 4, not shown).

Filed: 1937-05-14
Abstract: 492,831. Elastic - fluid turbines. TENNANT, W. J. (Aktiebolaget Milo) May 14, 1937, No. 13718. [Class 110 (iii)] A gas-turbine plant of the continuous-combustion type comprising a number of turbines, or turbine stages, and individual heating means for heating the gas to each turbine, has separate control means for each means of heat supply. Fig. 1 shows high and low pressure turbines 2, 3, high and low pressure compressors 4, 5, a starting engine 7 of any suitable type, an electrical generator 6, and two fuel pumps 8, 9, all on a shaft 1. The L.P. compressor 5 may be disconnected at a clutch 10. Air from the H.P. compressor 4 passes through a conduit 12 to a combustion chamber 13, and after being heated is led through a conduit 17 to the turbine 2. Exhaust gases from the latter pass through a conduit 18 to a combustion chamber 19 and then are led to the turbine 3. Fuel is supplied from a source 15 to the combustion chambers 13, 19, by means of the pumps 8, 9. The supply of fuel to the chamber 13 is controlled in response to the load on the plant by means of a governor 22. A thermostat 24 controls the fuel supply to the chamber 19. The thermostat 24 may be placed in the inlet conduit of the turbine 3. The L.P. compressor 5 is provided with a bleeder pipe 25 through which a portion of the air drawn in may be discharged. A valve 26 is under control of the governor 22. The air supply may be controlled by a thermostat. Fig. 2 shows a H.P. turbine 32 driving I.P. and L.P. compressors 33, 34, an I.P. turbine 35 driving a generator 36, and three fuel pumps 37, 38, 39, and a L.P. turbine 40 driving a L.P. compressor 41. The turbines are provided with heating chambers 42, 43, 44 supplied by the pumps. The governor 22 regulates the pumps 37..39. At a low load, the L.P. turbine is dispensed with. A further modification, Fig. 3, utilizes gas generators 85, 94, which supply H.P. and L.P. turbines 77, 78, respectively. The generator 85 has a stoker 80 fed with fuel from a hopper 81. Air compressed in a compressor 97 passes to a space 85 and then, partly through openings 87 to the zone of combustion, and partly through openings 86 to the chamber 79. The gas passes through a pipe 100 to the turbine 77, thence through a pipe 101 to the generator 94 where the excess air supplied to the generator 85 is used to burn the fuel on a stoker 89. The governor 22 controls the fuel supply in the hopper 81, the speed of the stoker, and the quantity of air supplied to the generators. The governor may also open a valve 105 in a byepass 104 through which a portion of the air may pass from the space 85 directly to the turbine without taking part in the combustion. The control valves 99, 105 are mechanically connected so that as one is opened, the other is closed. A thermostat 106 controls the supply to the L.P. turbine 78. Thermostats 109, 110 act as safety devices to open valves 105, 108 in the event of undue rise in temperature of the gases.
