Abstract: ABSTRACT       Nitration of organic compounds and organic nitrogen compounds produced.      Organic nitrogen compounds are formed in the vapour phase by organic radical formation by reaction of an organic compound with hydroxyl radicals derived from the reaction between hydrogen peroxide and nitrogen dioxide and the nitration of the organic radicals, suitably with nitrogen dioxide.  The process may be conducted as a single stage process using an excess of nitrogen dioxide over that required for hydroxyl radical formation.  The production of hydroxyl radicals is maximised by the use of a catalytic solid surface such as a solid acid or an acidic oxide or mixed oxide.  The product may be a mixture of some or all of the nitrite, nitrate and nitro-derivative which may be used as such, e.g. as a fuel additive, as a source of the individual compounds or as a feedstock for a further synthesis.

Abstract: ABSTRACT:     A method of simultaneously preparing a plurality of castings of a solution of an element or compound A in a solvent B which is an element and/or a compound, which solution is saturated at a temperature Ts.  A problem in liquid epitaxy growth processes is the simple preparation of growth charges which are of sufficiently reproducible composition and size to produce epitaxial layers of repro-ducible composition and thickness.  A melt 12 consisting of B, or of B together with at least one of the constituents of A, or of a solution of A in B which is unsaturated at Ts is prepared in a trough 5 of a boat body of a liquid-tight boat assembly 1.  An equilibrium is established at Ts between the melt 12 and a solid body 13 which is an excess of any constituent in which the melt 12 is deficient with respect to the saturated solution, so as to form a saturated solution.          The saturated solution is transferred into a plurality of moulds 9 in which this solution is allowed to solidify to form the castings.  The solid body 13 is contained in a solid-retaining portion 6 of the trough 5, which portion 6 is separated from the remainder of the trough 5 by an aper-tured partition 8.

Abstract: ELECTROMAGNETIC UNIT FUEL INJECTOR          Abstract of the Disclosure An electromagnetic unit fuel injector for use in a diesel engine includes a housing having a bushing with an externally actuated plunger recipro-cable therein to define a pump chamber open at one end for the discharge of fuel to a spring biased, pressure actuated fuel injection nozzle.  The pump chamber is connected to a supply and spill chamber means via flow-through solenoid actuated, normally open, hollow pressure sensitive valve to permit the ingress and egress of fuel.  The supply and spill chamber means adjacent to the head of the valve is in flow communication with a pressure equalization and spring chamber means at the opposite end of the valve via a passage through the valve and these chambers are in direct flow communication with a source of fuel at a relatively low supply pressure.          During a pump stroke of the plunger, the solenoid can be energized, as desired, to push the pressure sensitive valve to a closed position relative to an associate valve seat so as to block flow from the pump chamber to the supply and spill chamber means thus allowing the plunger to effect pressurization of the fuel so as to effect discharge of fuel from the injection nozzle.

Abstract: PREFABRICATED PLASTERED PANELS FOR HOUSING            ABSTRACT OF THE DISCLOSURE:         A method of construction of prefabricated plaste-red panels for housing, which comprises the steps of installing a rigid framework comprising a plurality of spaced apart studs onto a horizontal surface, filling up the spaces between the studs with a granular material such as sand, stretching and fixing a reinforcing material such as wire mesh, onto the upper surface of the framework, applying a layer of plastering material such as a plaster, stucco or cement onto the reinforcing material, using the granular material as formwork to support the plastering material until it is dry; and removing the framework with the dry plaster layer attached thereto from the horizontal surface.  This method is particularly interesting in that it does not request any equipment for the construction of the prefabricated plastered panels.  Moreover it does not request skilled labour and it makes use of low cost mate-rials only.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for separating discrete solid fractions by dispersion in a dense liquid medium wherein the suspended materials are subjected to settling to produce a low density fraction floating on the surface, a middlings fraction suspended in the liquid medium, and a high density fraction which sinks to the bottom.  The low density fraction is conveyed by the moving medium and discharges over an overflow weir, while high density fraction is lifted out in a region of the dense medium in which the surface level of the dense medium is substantially free from particles of the floating low density fraction.  The separated fractions are delivered to screen separators for separation from the liquid medium.

Abstract: ABSTRACT In a refiner with two opposed discs rotatable relative to one another, fibre pulp is manufactured from lignocellulose-containing material. The material is advanced in a channel comprising a plug pipe through which the material is fed in a compressed state, and a steam screen pipe for discharging steam.  The steam screen pipe is located directly after the plug pipe and has a cross-sectional area which slightly exceeds that of the plug pipe in order to allow a limited expansion of the material plug.  The steam is thereby allowed to flow through the material, at the same time as the material plug prevents clogging of the apertures of the steam screen pipe.

The mechanism has a series of spacer and conveyor elements (94) constrained cyclically to execute a working and return motion such that the elements move along a working path in the feed direction of the articles during which the elements interfere with the articles in the feed path so as to form and convey said groups along the feed path and move along a return path opposite to the feed direction of the articles during which said elements are remote from said articles.  The working and return paths are substantially parallel to the feed path, and the spacer and conveyor elements each have an operative face adapted to convey said articles in spaced relationship.  The elements are mounted so that they are held throughout their cyclic movement with their operative faces facing towards the feed path.

Abstract: ABSTRACT OF THE INVENTION          The invention provides a light source for use with diagnostic devices such as laparoscopes having a male fitting to receive a light tube connection for transmitting light within the device to an end for viewing using an eyepiece on the device.  The light source has an elongate casing and an electrical storage battery contained in the casing.  The battery extends longitudinally and has first and second poles at opposite ends of the battery.  A tubular insulating insert is positioned inside the casing at one of the ends of the casing and adjacent the first of the poles.  A bulb is located in the insert and has the center terminal of the bulb in electrical connection with the first pole.  First and second contacts are insulated from one another and located by the insert with the first contact coupled to the body of the bulb and the second contact coupled to the second pole.  Both the contacts project slightly inwardly within the insert whereby when the light source is pushed over the male fitting, the light source is located on the diagnostic device and the male fitting completes the electrical circuit.  The bulb is then powered so that light passes through the device to the end of the device.
