Title: Method of and device for regulating the supply of tobacco to cigarette making machines
IPC: A24C5/34
Filed: 1932-11-14
Abstract: 401,114. Cigarette-making machines ; weighing-apparatus. BLOCK, F., 107, Feldstrasse, Wandsbeck. and NEUERBURG'SCHE VERWALTUNGS-GES., 19, Br³ckenstrasse, Cologne, both in Germany. Nov. 14, 1932, No. 32211. [Class 130.] In automatic regulating mechanism for the tobaccofeed supply of cigarettemaking machines, the mechanism is initially set to feed progressively decreasing or increasing amounts producing underweight or overweight cigarettes, and, after delivery of a predetermined number, the feed is conversely increased or decreased to deliver an equal number of overweight or underweight cigarettes, whereafter the foregoing cycle is repeated. The shaft 14 determines the feed rate and is initially driven from a shaft 1 through a clutch 4, toothed gearing 6, 7, a friction clutch 7, 8, shaft 10, and worm-and-wheel 12, 13. An electric motor 17 is also geared to the shaft 10. After delivery of a certain number to a weighing mechanism, a shaft 45 is turned and rotates one of the ratchet wheels 42, 44, thereby swinging a switch quadrant 20 provided with contacts 21, 22. The fixed contacts 24 .. 27 are in circuit with the field windings 30, 31 of the motor 17. Current is delivered periodically when the segment 37 on the rotary disc 36 engages brushes 34, 35. The resulting movement of the motor opposes that imparted by the shaft 5 to the regulating shaft 14, slipping occurring at the clutch 8, 9. Should the alteration in speed be insufficient, the further movement of the quadrant breaks the circuit of the winding 30, and the speed of the motor is increased. A final movement of the quadrant to the right due to extreme inadequacy of feed closes the circuit of an alarm or lamp 32.

Title: Improvements in or relating to a method and apparatus for testing the presence of specific atomic elements in a substance
Inventor: PUTMAN JOHN LABAN
IPC: G01V5/10
Filed: 1953-11-21
Abstract: 755,967. Analysis by neutron beams. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 22, 1954 [Nov. 21, 1953], No. 32342/53. Class 40 (3). The presence of specific atomic elements is detected by irradiating the substance under test with neutrons detecting by means of a scintillation detector gamma rays emitted as a result of the neutron bombardment and analysing the output pulses of the detector to indicate the pulse rate in particular ranges characteristic of the element to be detected. The invention is described with reference to determining the presence of chlorine in a hydrocarbon oil in a pipe D (Fig. 1). A polonium - beryllium neutron source is mounted outside or inside the duct. A thalliumactivated sodium iodide crystal which with photo-multiplier PM constitutes the scintillation detector is separated from the neutron source by a cadmium screen Cd. The output pulses from the detector are amplified and fed to a pulse analyser which selects pulses corresponding to gamma intensities characteristic of the element to be detected and the pulse rate is indicated on meter RM. In the arrangements of Fig. 2 (not shown) and Fig. 3, a probe comprising neutron source S, photo multiplier PM and crystal X surrounded by a cadmium sheath Cd is lowered into a bore hole to determine the nature of the strata surrounding the bore. Since various elements however emit gamma rays having more than one distinctive amplitude, a number of pulse analysers set to respond to different amplitude levels are connected to the amplified detector output. These analysers each operate a recorder. Thus if the first recorder indicates the presence of a peak corresponding to the element the subsequent recorders should indicate the subsidiary peak corresponding to the element. Specification 750,328 is referred to.

Filed: 1926-12-23
Abstract: 264,475. Warluzel, C. Jan. 12, 1926, [Convention date]. Liquid-level pressure gauges.- Apparatus for measuring pressures consists in the provision of a capacity of constant volume, means for introducing gas into said capacity under the pressure being measured, and means for measuring the volume of the gas after expansion to a pressure chosen as a unit. A tube 1 is closed at one end by a plug 2 and at the other end by an obturator 3 which receives a capillary tube 4 open at both ends. The tube 1 is filled with water up to the level 5, leaving an air-space 7. The whole is located in a tube 8 forming a diving bell and, in the example given, fastened to the lead of a sounding device. As the apparatus sinks, water rises in the bell and compresses the air into the space 11, from which it passes through the capillary tube to rise into the space 7, increasing the pressure therein. When the device is raised, the air in the space 7 expands and forces water out of the tube 1 through the capillary tube. The initial and final pressures being the same, the pressure to be measured is given according to Mariotte's Law by the ratio of the volumes occupied by the air in the tube 1.

Title: Improvements relating to the evaporation or distillation of water
Inventor: WOOD LEO KELLETT DONALDSON
IPC: B01D3/00
Filed: 1952-12-23
Abstract: <PICT:0762083/III/1> Sea or other raw water is purified by bringing it, preferably in the form of spray, into direct contact with hot gas such as combustion gases, air, or a mixture of steam and air, whereby the water is heated, subjecting the heated water to flash vaporization at a lower pressure, and condensing the water-vapour so obtained. The method obviates the formation of scale on heat-transfer surfaces.  The water may be preheated in the condenser prior to being contacted with the hot gas.  If heated by combustion gases, the water is preferably de-gassed to remove carbon dioxide before being subjected to flash vaporization.  A hot mixture of combustion gases and air is produced in chamber 10 which is provided with oil burner 11, and is connected to water-heater 14 by duct 46.  Air is supplied to the chamber by a fan (not shown) through inlet 44 and annular passage 45, which surrounds the chamber and the duct.  The duct is thus kept cool, and the air is preheated to about 150 DEG C.  The duct 46 projects into heater 14; and the space round the lower end of the duct is packed with Raschig rings 48.  The water-to-be-purified is introduced into the system through pipe 39, and is sprayed through spray-heads 16 and 49 into heater 14 where it is contacted with gases at 1000 DEG C. entering through duct 46.  The water is thereby heated to about 50 DEG C., while the gases are cooled to about 70 DEG C. The hot water is pumped to degasser 33 which has an air inlet 34 and an air outlet 35.  The majority of the CO2 content of the water is eliminated in the degasser, and the sulphur compounds are connected to sulphuric acid.  The degassed water is passed through spray pipe 37 into flash chamber 36 which is maintained at a pressure of 70 mm. Hg.  Part of the water is vaporized, and the vapours pass off overhead to condenser 17.  The condensate, which is pure water is removed by pump 21.  Some of the brine from flash chamber 36 is recirculated by pump 38 to heater 14, and the remainder is withdrawn from the system through blowdown 23.  In another embodiment, the water is heated by contacting it with a hot mixture of steam and air circulating between the water-heater and a heat-exchanger wherein the mixture is reheated by hot combustion gases.  Waste combustion gases from a steam boiler installation may also be used to contact the water.

Abstract: 1,188,510. Electric generators. ROBERT BOSCH G.m.b.H. 19 July, 1967 [20 July, 1966], No. 33066/67. Heading H2A. In a generator for producing a triggering ignition impulse, the pick-up coil 31 receives flux from a pole-shoe 107 whose leading edge is so curved that the required threshold voltage is reached sooner at higher speeds, thus providing automatic spark advance. The rate of increase of width of the pole-shoe 107 presented to stator pole 55 is inversely related to the angular position so that a required rate of flux charge will depend on its angular position with respect to this pole, in addition to the rate of rotation. The shaped pole-shoe 107 is part of a cylindrical or conical surface 108, from which it is magnetically isolated but which carries the working flux not employed at any instant. This flux is generated by a permanent or electromagnet 54 and passes through shunt 111 to the surface 108, or through core 65 carrying the coil 31, depending on the position of the rotating pole 55. The polepieces may be laminated or of ferrite.
