Title: Improvements in or relating to mixture-compressing internal combustion engines and methods of controlling their operation
IPC: F02B19/10
Filed: 1956-03-02
Abstract: 778,553. Regulating; spray carburetters; working cycles. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. March 2, 1956 [March 4, 1955], No. 6633/56. Drawings to Specification. Classes 7 (2), 7 (3) and 7 (6). In an engine in which each cylinder has an ante-chamber provided with an ignition device, in which a rich fuel-air mixture is formed by injection of fuel, a lean fuel-air mixture being supplied directly to the main cylinder space, control of the engine from zero load to half load is effected quantitatively (i.e. by variation of the quantity of mixture) whilst from half load to full load the control is qualitative (i.e. by variation of the composition of the fuel-air mixture). From zero load to half load the supply of lean mixture of constant fuel-air ratio is controlled by a throttle valve, the supply of fuel injected into the ante-chamber by a fuel injection pump being conjointly controlled, either by a connection from the throttle valve or by a device actuated by intake pipe suction, to maintain a substantially constant rich mixture strength in the ante-chamber. Beyond half load the throttle valve is maintained fully open and an additional jet in the carburetter is gradually opened to increase the strength of the lean mixture. The amount of injected fuel may be either decreased slightly from half load to full load, to compensate for the increasing mixture strength of the mixture passing from the main cylinder into the ante-chamber, or may be maintained constant. In a modification the single carburetter supplying the lean mixture is replaced by two carburetters brought into action in succession. Specification 722,044 is referred to.

Title: Featherdown felt and methods of manufacturing the same
IPC: D04H1/64
Filed: 1936-03-09
Abstract: An air-permeable felt-like material comprises small feathers or feather down in loose contact with one another and held together by discrete adhesive particles.  The adhesive is applied in finely-divided solid or non-solid condition.  A liquid adhesive may be atomized in a closed chamber, and allowed to settle on subsequently introduced featherdowns.  The chamber may be provided with movable sieve-like top and bottom portions between which the layer of featherdowns is retained while the adhesive is being hardened.  Glue solution may be used, atomized in moist, warm air and hardened by passing cold air through the featherdown layer between the seive inserts, or an adhesive dissolved in a volatile solvent, or a heat-sensitized rubber latex may be used and hardened or set by the passage of hot air.  Finely-powdered, solid, fusible adhesives, e.g. a resin such as colophony may be thoroughly mixed with the featherdowns, and the featherdowns agglutinated by heating to fuse the adhesive, and subsequently cooling.  Shaped objects may be made by compressing the p  featherdowns mixed with powdered adhesive in moulds, which may have permeable walls, heating and cooling being effected by passing hot and cold air therethrough.  The moulds may be lined with textile material or paper or sprayed internally with cellulose derivative, such layers remaining attached to the felt. Endless webs may be produced by introducing the featherdowns and adhesive powder between porous, e.g. textile or paper bands, and passing hot, then cold air through the porous bands and enclosed featherdown layer.  The textile or paper material may be left secured to the featherdown layer.  The material may be used for filling quilts or cushions, lining garments, for sound insulation, and air or gas filters for internal-combustion engines, cigarette tips, and gas masks.  Active carbon may be incorporated when the material is to be used as a gas filter.ALSO:An air-permeable felt-like material employable in gas-mask filters comprises small feathers or feather down in loose contact with one another and held together by discrete adhesive particles such as glue, rubber latex, or resins, e.g. colophony.

[Also in Divisions F2 and G3] Enhanced discrimination and sensitivity in the gas chromatographic analysis of samples held in tube 11 is achieved by heating tube 11, through which carrier gas is passing, so rapidly that transfer to column 13 is achieved by thermoinjection, the carrier gas being passed through flow resistrictor 18 upstream of the precolumn so as to establish sufficient pressure differential to prevent back pressure. Initially, a sample is passed through selection unit 110 in a stream of carrier gas, valve 19 (see Division F2) being kept open by a flow of carrier gas from source 17, so that the sample condenses and is trapped in tube 11 which is immersed in a bath 12 of solid carbon dioxide or liquid nitrogen. When the trapped sample is to be investigated, valve 19 is closed by carrier gas from source 20 and valve 15 is closed to the atmosphere by carrier gas from source 16. Tube 11 and contents are then heated for less than 1 second to 150-200‹C., causing the sample to volatilise and be carried to column 13 in the stream of carrier gas. Constructional details are also provided of gas flow restrictors 18, 112 (see Division G3), of thermoinjector tube 11 and of selection unit 110, which latter enables the system to be operated in a number of different modes for different purposes.
