Abstract: 1471916 IC engine fuel injectors PLESSEY CO Ltd 31 Jan 1975 [14 March 1974] 11407/74 Heading F1B [Also in Division F4] The nozzle 3 for injecting liquid fuel into the air inlet passage 1 of a two or four-stroke engine, a central heating boiler or a gas turbine engine, e.g. a passage between the air compressor and the burners of a turbojet, comprises a vibrator 6, e.g. a Piezo-electric element for producing ultrasonic vibrations, an injection orifice 13, a valve 15 which closes the orifice when the nozzle is not vibrated and a wall 17 defining an aperture 20 at a position where the valve will tend to move when the nozzle is vibrated. The aperture 20 permits fuel fed under pressure through passages 11, 16A to act on the valve 15 to tend to move it towards the seat 14. The wall 17 may have tangentially extending bores 16 adjacent the seat 14 to promote swirling of fuel within the chamber upstream of the seat. The wall 17 may be provided by an insert, Figs. 3 to 6 (not shown), in the member defining the orifice, Fig. 3, or brazed at four circumferentially spaced regions (27), Fig. 6 to the wall of the nozzle portion 2. The inner surface (19) of the insert is curved in the region of the aperture 20. The valve 15 may be spring-biased against the seat 14 and may be moved from the seat by a solenoid winding 18 energized with the vibrator 6. The valve 15 may be made of magnetized steel or of non-magnetic material and connected to a magnetic armature, the nozzle portion 2 being made of non-magnetic material. The vibrator 6 may be energized for uniformly spaced adjustable parts of the cycles of an engine.

Abstract: The invention relates to an oblong sign board casing comprising a reflector sheet provided with parallel embossings extending in planes substantially perpendicular to a longitudinal axis. The profiled reflector sheet is curved about 90 DEG  round a longitudinal axis, whereby a self-supporting construction is obtained. This construction renders it possible to provide the front plate with a flange and a sharp edge at the bottom. The embossings cause an effective diffusion of the light, also towards the bottom face.

Abstract: Expandable styrene polymer particles having reduced flammability are made by incorporating from 0.1 to 15 weight percent of non-polymeric organic halogen compounds into the polymer during impregnation of the polymer particles with a blowing agent in aqueous suspension. The addition of 0.001 to 0.5 weight percent of dialkyl tin maleates or fumarates during the impregnation step produces expandable styrene polymer particles with greatly improved molding characteristics such as reduced pruning tendency, increased mold fusion, and greater dimensional stability. Addition of a synergistic amount of 0.001 to 0.4 weight percent of a hindered phenolic antioxidant with the tin compounds gives improved molding characteristics with retention of polymer molecular weight.

Abstract: An automatic thickness analyzer is provided which automatically measures the thickness of a metallic film deposited on an insulating substrate e.g. plated through holes of printed circuits. A direct current increasing at a constant rate 125, 150 is applied to the conductors of a plated-through hole 350. If the metallic film burns out before the maximum output of the analyzer is achieved, the value of the current corresponding to the burn-out current is captured and held by circuit 200 and the held valve applied to a display meter 250 until it is manually reset by 325. An empirical relationship allows automatic conversion of the burnout current to the corresponding thickness of the metallic film. Burn-out shutdown circuit 275 responsive to the burn-out current inhibits the sample and hold circuit 200 and inactivates the current generator 150. If the metallic film does not burn out before the maximum current capacity of the analyzer is reached, current limit shutdown circuitry 300 is automatically activated. <IMAGE>

Date May 1, 1980.In electrical discharge apparatus, such as a gas laser, in which a glow discharge is to be produced in a gas between two electrodes, at least one pre-ionizing member is placed near the discharge space and extending between the electrodes so that current flows in the member which is made of intermediate resistivity material such as crystalline semiconductor material. As a result, the discharge space is pre-ionized which assists initiation of the main discharge. The pre-ionization may be due to the formation of numerous small arcs between the electrodes and the member and the resulting production of ultra-violet light.

Abstract: A sensor element adaptable for measurement of a physical parameter formed of a crystalline material and emitting luminescent spectra upon excitation by light spectra and the influence of said physical parameter. A first layer emitting luminescent spectra is formed of a semiconductor material containing dopant providing shallow energy levels and recombination centers with a concentration between 1015 to 1018 cm-3, and sandwiched between second and third layers of semiconductor material having low absorption for light excitation of the first layer, and the respective lattice constants of the second and third layers being substantially coincidental with the lattice constant of the first layer. The sensor element is formed of GaAs for the substrate and AlGaAs for the semiconductor layers, with appropriate variation in the concentration Al, Ga, and As for the various layers. Generally, the energy band gap of the layers sandwiching the luminescent emitting layer are higher than that of the emitting layer. In a modified embodiment, GaAs is used as the luminescence emitting layer with covering semiconductor layers of AlGaAs, with appropriate variation in the concentration of Al, Ga and As. In a further modification an additional semiconductor layer of AlGaAs is sandwiched between the active semiconductor layer and a non-active semiconductor layer to reduce or eliminate a shift in the wavelength emission of the sensor element.
