Abstract: 969,687. Harnesses. G.Q. PARACHUTE CO. Ltd. June 10, 1963 [June 8, 1962], No. 22268/62. Heading A3V. A harness for workmen, constructed so that should the wearer fall he will be supported in a sitting position, comprises a seat sling unit 13, Fig. 1, having leg straps 15, and a waist and side strap unit 27, Fig 2, having D-rings 30 on its ends. The webbing of this strap is brought back on itself and doubled to form loops 29, the part of the unit between loops 29 and D-rings 30 constituting the side strap. The two units are connected by flexible rings 31, 32 (Fig. 6) of cord, string or the like. In use D-rings 30 are connected to hooks on e.g. the window frame, the weight of the wearer being carried through the waist and side-straps to the fixed support. Should the wearer slip, the loops 29 in the side straps slide on rings 31, 32 or these rings distort so that the weight of the wearer is transferred from the waist strap 27 to the seat-sling 13 and the wearer is supported in a sitting position. Additional parts such as chest and shoulder straps (Fig. 6) and an adjustable waist belt may be provided if a full harness is required. Additional supporting straps 11 carrying D-rings 10 and having loops 12 which pass through rings 31, 32, may also be provided, the D-rings being connected to further supporting hooks. Parts of the harness may pass through guiding tunnels in a protective overall. The harness is readily dismantled to repair or replace damaged strap elements.

Title: Method of increasing the cetane number of a compression ignition engine fuel
IPC: F02B3/06
Filed: 1955-08-05
Abstract: Fuel for a compression ignition (diesel) engine is contacted at a point between the fuel tank and the injectors with a solid dispersion of finely divided alkali metal whereby the metal is released and suspended in the fuel prior to injection into the combustion chamber to increase the cetane number of the fuel.  The dispersion medium may be a solid hydrocarbon, such as a petroleum wax, or a solid ether, and may contain a modifying agent, such as a solid or liquid hydrocarbon or ether, or an activated bentone, to maintain the physical characteristics of the dispersion constant between -50 C. and +70 DEG  C., and may also contain a dispersing agent.  In examples sodium is dispersed in naphthalene, diphenyl, p-di-ethoxy benzene and durene, and petrolatum, kerosene, petroleum distillate, paraffin wax, and n-butyl-n-propyl ether are used as modifying agents, and oleic acid is used as a dispersing agent.  Other alkali metals mentioned are potassium, lithium, rubidium and caesium.  Other dispersing media mentioned are acenaphthalene, 1- and 2-phenyl naphthalenes, and diphenylene oxide.  The concentration of alkali metal in the dispersion may be between 10 and 85 per cent by weight. The fuel may be a diesel fuel, but other hydrocarbon fuels, such as motor gasoline and aviation gasoline, may be used.

A tobacco distributer with a radial centrifuge 128 has an axial intake connection 126 and an outlet slot 137 at the periphery into which opens a co-axial ring- shaped delivery duct 169 which embodies an opening 176 covered by an air permeable rotatably driven screen 140 disposed radially outwardly of the centrifuge and a second opening 174 disposed radially outwardly of the centrifuge, and means for blowing air through the opening 174, screen 140 and opening 176 in succession. Tobacco 104 is fed by the assembly 103, 105, 116 and 106 to a weighing device 108-113, which may be as described in Specifications 1,065,731 and 1,079,288, which delivers it in weighed amounts to a conveyer belt 123 leading to the centrifuge intake 126. A vertically adjustable roller 124 minimises the entry of air into the intake 126, controlled amounts of air being admitted if necessary through a pipe 164. The intake 126 opens into the centrifuge 128 consisting of a fixed disc 129 and a lower disc 130 driven at high speed by a motor 136 connected to a pulley 134. The distributed tobacco is forced outwardly through the slot 137 and into the duct 169 where is forms a ring of tobacco 150 on the screen 140 which is mounted on a carrier 138 rotatably driven by a pulley 166. The centrifuge is arranged in a casing 127 divided into air chambers 142 and 143. A blower 149 blows air into the chamber 142 through a connection 152, the air passing through the screen 140, and serving to hold the tobacco thereon, before returning to the intake of the blower from, chamber 143 via a connection 148. The screen 140 passes at one part of its peripheral travel into an off-take pipe 146 through which air is blown by a blower 147 to remove the tobacco from the screen for subsequent processing. In an alternative embodiment two distributers are connected in series (Fig. 2, not shown). The first distributor is arranged substantially as the distributer of Fig 1 and the off-take pipe leads directly into the axial intake of the second distributer. The second distributor is arranged so that both discs of the centrifuge rotate and the off-take may be effected tangentially of the screen by conveyers or by a suction pipe (Figs. 3 and 6, not shown). The air chambers of the distributers are connected so that air passes from the blower into the upper chamber of the first distributer, through its screen and into the lower chamber of the first distributer, thence into the upper chamber of the second distributer, through its screen and into the lower chamber of the second distributer, and finally back to the blower. A branch connection may provide the air for the off-take pipe of the first distributer.

Abstract: 716,624. Cathode-ray tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 9, 1951 [Oct. 12, 1950], No. 23456/51. Class 39(1) In a cathode ray tube in which a ribbon beam after passing through accelerating electrode 3, Fig. 2, is deflected over a collecting electrode by two deflecting plates 9, 10 flaring away from the cathode, the electrode arrangement is such that when a fixed potential is applied to plate 9 and a varying potential to plate 10, the potential distribution in the region of minimum separation of the plates 9, 10 is determined predominantly by the fixed potential plate 9 so that the focal length of the beam, which is determined by the lens effect of the potential distribution, also remains constant. In one form, Fig. 2, the accelerating anode 3 has an eccentric aperture close to plate 9 and the edge of plate 10 is bent away from the beam. In another form, Fig. 3 (not shown) the electrodes are symmetrical except for two rods or strips close to the variable potential plate which screen the beam from the latter plate. The rods or strips are kept at a fixed positive potential and are preferably connected to the fixed potential deflecting plate. The collecting electrodes are at cathode potential (the perforated one) and at 250 volts (the imperforate one) and the fixed and variable deflecting voltages are 150 and 70-230 volts respectively. 2 is a focusing electrode. The device may be used in relays or counting systems.
