Abstract: 941,448. Treating charge. R. BOUTELEUX, and H. GRIFFON. July 25, 1961 [Dec. 9, 1960], No. 26888/61. Heading FIB. A device for homogenizing a combustible mixture to form a fuel for reciprocating I.C. engines comprises a member adapted to be positioned within a cylinder head adjacent each inlet valve, which member is elongated in the direction of flow and includes a base, a perforated zone in which the total cross-sectional area of the apertures is at least equal to the cross-sectional area of the duct to which the member is fitted, and an imperforate end portion against which liquid fuel drops carried along by inertia are atomized and are dispersed in the gas flow passing through the member. A member, Fig. 1, of any suitable substance such as metal or polymerized plastics has rows of perforations 6 and 7 so inclined as to cause the fuel mixture to whirl in opposite directions to produce turbulence and thereby assist in homogenizing the mixture. Additionally, helical grooves may be provided in the internal surface of each of the apertures to help the latter to impart a whirling motion to the mixture. Any liquid particles in suspension are hurled by inertia against the inner surface of the base 5 to be atomised and returned to the gas stream. The base may protrude into the member with a convex inner surface or the member may have a ball fitted in its downstream end to produce, inside the member, a hemisphere upon which the liquid particles impinge and, on the outside a hemisphere which may be used for location purposes. Where the base 5 is flat a protruberance may be provided inside the member on the imperforate part 2 to compress the mixture and help it to expand subsequently through the apertures. The member may be made to fit a particular inlet conduit, as shown in Fig. 5, and may have a locating projection 22. In an alternative embodiment (not shown) the member is double-walled, with a heating fluid flowing in the cavity between these walls to heat up and thereby gasify the still liquid particles of fuel. The member is mounted in a cylinder head to communicate with the water chamber, longitudinal partitions being provided between the walls to guide the water to flow from the inlet to the outlet, both at the upstream end of the member, by way of the base.

Title: Improvements relating to electric discharge lamps of the low pressure type
Inventor: CLARKE MAURICE GEORGE
IPC: H01J61/10
Filed: 1956-09-03
Abstract: 867,033. Fluorescent discharge lamps. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 3, 1957 [Sept. 3. 1956], No. 26889/56. Class 39(1). In a low pressure positive column discharge lamp having a fluorescent coating on the inner surface of the envelope, the discharge path between the electrodes is effectively shortened by means of an electrically conducting member extending along the axis of the envelope from the neighbourhood of one electrode to that of the other electrode. The conducting member is unconnected to either electrode, is without an insulating coating and is free from occluded gases, and has a sufficiently high thermal conductivity and thermal capacity to avoid the formation of hot spots capable of constituting arc roots. It may be in the form of a nickel rod 6, dimensions are given, supported by spiders 5 engaging the inner wall of the envelope. On pre-heating the electrodes 2 to an electron-emitting temperature and applying between them the normal operating voltage, the discharge starts immediately, and is not short-circuited by the rod 6 but is deflected away from the axial position into closerproximity to the luminescent coating on the wall of the envelope, thus affording an increase in brightness. The envelope may contain a filling of inert gas at a pressure of 3mm. of mercury and a mercury droplet to provide a saturated vapour. Specification 625,256 is referred to.

Title: Providing cast-iron articles with a cell-like surface
IPC: F16H47/06
Filed: 1937-10-05
Abstract: A cell-like surface, which will retain lubricant when subjected to friction at high temperature or pressure, is formed on cast iron articles, e.g. piston rings, by using a cast iron containing more than 0,15 per cent of phosphorus and subjecting the articles to chemical treatment to remove to some extent the material within the polygonal network formed by the phosphorus-rich constituent, leaving the latter in relief.  The article is preferably first degreased and then coated with copper, by chemical deposition or electrolysis, in a neutral or acid copper salt solution, or first in a neutral and then in an acid bath.  It is then rinsed, e.g. in water or alcohol, and placed in an acid which will dissolve copper, preferably concentrated nitric acid; adhering acid is neutralized, preferably with sodium carbonate solution, and the article is washed.  This treatment produces the cell-like or honeycombed surface.
