Title: Improvements in apparatus for supplying vaporized or heated fuel to internal combustion engines and furnaces
IPC: F02M69/00
Filed: 1931-05-04
Abstract: 378,411. Liquid fuel burners. NETTEL, F., 7, Ban, Minami Peramachi Mita Shiba, Tokio. May 4, 1931, No. 13178. Convention date, May 2, 1930. [Class 75 (i).] Fuel is supplied to a furnace either in liquid form or as a vapour, under a pressure produced in a chamber a by burning a portion of the fuel in the chamber. A flame is maintained above the surface of the liquid by a supply of air or oxygen admitted at g at a pressure greater than that within the chamber a regulating valve i in the air or oxygen supply pipe maintains the pressure and temperature in the chamber a constant irrespective of the consumption of fuel which is supplied under pressure through a pipe b. The heated or vaporized fuel leaves the chamber at h, its state depending on the position of the intake of the outflow pipe relative to the liquid level. If the fluid is to be supplied as a liquid the pressure in the chamber may be regulated by controlling an outlet c for the products of combustion ; this outlet is partly closed when vaporized fuel is supplied by the apparatus. Combustion is initiated by b.enzine admitted at d and ignited by an electric igniter e. A small opening to admit atmospheric air may be provided to maintain the combustion when the apparatus is not supplying fuel. Solid fuels, which are liquefied by heat, may be utilized.

Patent GB-773432-A (GB)
Title: Improvements in or relating to the production of secondary aliphatic amines
IPC: C07C209/48
Filed: 1955-05-09
Abstract: Secondary amines are produced by hydrogenating aliphatic nitriles at 140-240 DEG  C. and 100-1000 p.s.i.g. in the presence of a copper-chromium oxide catalyst; it is not then necessary to form primary amines as intermediates.  The nitrile preferably has 8-22 carbon atoms and may be saturated or unsaturated, the double bonds in the latter being unaffected.  Particularly suitable are unsaturated nitriles of 14-22 carbon atoms, e.g. those of 18 carbon atoms and 1-3 unsaturated linkages.  Preferred conditions are 150-215 DEG  C. and 200-400 p.s.i.g.  An inert solvent may be used but is not necessary. Formation of tertiary amines is suppressed by the addition of caustic alkali.  The products can be quaternated, e.g. by treatment with methyl chloride.  Examples show the hydrogenation, under various conditions, of the nitriles of tallow and soya fatty acids and of n-dodecyl nitrile.ALSO:A copper-chromite catalyst is prepared by mixing aqueous solutions of copper sulphate, sodium dichromate and ammonia, drying the precipitate and heating to a temperature not exceeding 320 DEG C. (c.f. J. Ind. Eng. Chem., 1934, 26, 878).  It is also stated that commercial copper-chromite catalysts may be stabilized with barium oxide.

Abstract: 1313042 Coated threaded fasteners LONGLOK FASTENERS CORP 5 May 1971 [13 May 1970 19 April 1971] 13388/71 Heading B2E [Also in Division F2] A threaded fastener having self-locking characteristics by virtue of a patch of thermoplastic material blended to a plurality of threads of the fastener is produced by heating the fastener to a temperature in excess of the melting point of the thermoplastic material but below the decomposition temperature thereof, and applying a solid unitary blank of the thermoplastic material to the heated fastener at a preselected location thereon to cause the heated crests of the threads engaged with the blank to divide the blank into discrete segments, which segments melt and flow into valleys of adjacent threads at the preselected location to bond to adjacent flanks of the threads defining the valleys and form a cohesive patch of solid material at the preselected location. The thermoplastic material may be polyester, preferably polyalkylene phthalates. Other suitable polyester resins are listed. The fastener may be a nut or a bolt and may be degreased and/or grit blasted prior to application of the thermoplastic material. The fasteners may be cadmium-plated or preferably of carbon steel and plated with cadmium after the patch is applied. As shown in Fig. 5 a blank 22 of thermoplastic material is deposited on the screw thread of a bolt 20, heated to above the melting point of the thermoplastic material and a pressure shoe 25 contacted with the blank 22 under the pressure of a spring for about one second. The softened blank sags into the valleys of the screw thread and forms pools 28 on the bottoms of the valleys of the screw thread as shown in Fig. 7. Preferably the heated fastener is then quenched in water. The resiliency of the plastics patch may be increased by subsequently soaking the, fastener in an oven after the quenching. In another embodiment a pressure shoe to form the plastics strip to the curved configuration of the screw fastener is in the form of a metal cradle having a longitudinal cavity that conforms to the cross-sectional curvature of the lower half of the horizontal screw fastener (Figs. 8-14 not shown).

Title: Improvements in or relating to apparatus for determining the distance of an object by means of a reflected radio wave
IPC: G01S13/36
Filed: 1940-09-09
Abstract: 574,965. Radiolocation. LAWSON, D. I., and PYE, Ltd. Sept. 9, 1940, No. 13999. [Class 40 (v)] [Also in Group XXXVI] In apparatus for determining the distance of an object by means of a reflected radio wave, an ultra-high frequency wave produced by a transmitter 1, is frequency modulated with sinusoidal modulation of high frequency from a modulator 2. The ultra-high frequency waves are transmitted from an antenna 3, reflected from the ground or other object whose distance is to be determined, received on an antenna 4, and passed to the first detector of a superheterodyne receiver 5. The output from this is amplified and limited to a predetermined level in an intermediate frequency amplifier and limiter 6 and passed to a converter stage 7 where the frequency modulation is converted into amplitude modulation which is rectified by a second detector 8. This modulation is passed, together with some of the output of the modulator 2 which has passed through an attenuator 9, into a rectifier 10. The output from this depends upon the altitude of the transmitter and receiver above the ground, and is indicated on a meter 11, calibrated in altitudes. Some of the transmitted signal may be fed into the receiver in opposite phase to the directly received signal so that the received reflected signal at the grid of the first valve is greater than the directly received signal.

Abstract: In a smoking article, a part of the tobacco filler is in the form of a film, coating &c. consisting of finely divided or colloidal-like particles.  Tobacco leaves are broken up and dry-ground in a ball mill or in a plate or disc colloidal mill, the product being mixed with 6-8 times its weight of water or other neutral liquid to form a slurry.  Alternatively, the grinding may be effected in the presence of the water &c.  If the slurry is not to be used at once, a preservative is added to prevent fermentation.  The slurry may be heat treated in an autoclave to hydrate the tobacco if this has not been effected previously.  Tobacco leaves or leaf portions to be coated are dipped in the slurry but it is preferred to spray shredded tobacco whilst being tumbled in a rotating drum.  In either case the product is dried to remove excess moisture.  The filling may be treated before or after being formed into its final shape, coating in the latter instance being applied to the binder or wrapper or to both.  Specification 570,265 is referred to.
