Title: Improvements in or relating to the production of spatter finish coatings
IPC: B05B7/12
Filed: 1961-01-11
Abstract: 923,475. Spray-producers. BERGER, JENSON & NICHOLSON Ltd. Jan. 11, 1961 [Jan. 21, 1960], No. 1247/61. Class 69 (3). In order to provide a spatter coating by two liquids applied simultaneously to a surface, the liquids are separately fed to a gun 16 and emitted from the outlet 43 of a chamber 41 whereupon the two liquids are atomized by air streams from a surrounding array of openings 38 and from additional openings 35. One liquid is supplied to the chamber through a passage 48, Fig. 1, and the other liquid is fed to the bore of a trigger controlled needle valve 45 having a flexible discharge head 44. The needle valve is normally urged forwardly by a spring 47 whereby both liquid outlets are closed, Fig. 7. When the trigger 19 is fully retracted an air valve 25 is opened and the outlet of the head 44 is positioned as shown in Fig. 6, within a converging part of the chamber 41. The two liquids are contained in receptacles 7, 8, Fig. 1, subjected to air pressure from a line 11, a pressure-reducing valve 12 and connections 13, 14. Liquid from the receptacle 7 is fed to the chamber 41 via a hose 53, valve 51 and rigid tube 50, and liquid from the receptacle 8 is supplied to the needle bore via a hose 65, valve 63, rigid tube 61, an elbow fitting 59 and a collar 57, Fig. 2. The line 11 also supplies atomizing air to the gun through a fitting 70 and the air flow is controlled by a further valve 31. A rigid strap 69 connected between the parts gives rigidity to the assembly. In Fig. 10, the needle valve head 44a has opposed flat surfaces 73 and, curved side surfaces 75.

Title: Improvements in or relating to the manufacture of malonates and cyanoacetates
IPC: C07C69/38
Filed: 1948-01-19
Abstract: One of the active hydrogens of the compounds Z,CH2.COOR and Z.CH2CN (where Z is hydrogen or an organic radical and R is a lower alkyl group) is replaced by the group -COOR1, where R1 is a lower alkyl group, by reacting the compound with sodium hydride and a carbonate R12CO3 and treating the product with an acid.  Other alkali metal hydrides, e.g. lithium hydride, may be used in place of sodium.  Z is preferably phenyl or a lower alkyl; the remaining free hydrogen atom may be replaced by a lower alkyl group such as ethyl, by treatment of the alkali metal derivative with the requisite ethyl inorganic acid ester, e.g. sulphate.  The alkali metal hydride is used in slight excess in an inert solvent, e.g. toluene.  In the examples: (1), (2), sodium hydride and diethyl carbonate are treated with ethyl phenylacetate to give diethylphenylmalonate, which (3), (4) is treated with diethyl carbonate or sulphate to give diethyl ethylphenylmalonate; and (5)-(10) diethyl carbonate and sodium hydride are reacted with ethyl acetate, ethyl butyrate, ethyl p-methoxyphenylacetate, ethyl p-chlorophenylacetate, ethyl a -naphthylacetate, and benzyl cyanide, respectively.  Phenobarbital is prepared by the condensation of urea with a dialkyl ethylphenylmalonate.  The Specification as open to inspection under Sect. 91 comprises also the statement that the groups R and R1 may be alkyl. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to devices for automatically adjusting the fuel injection timing of internal combustion engines
IPC: F02D1/00
Filed: 1940-01-27
Abstract: 534,324. Adjusting injection timing of internal-combustion engines. BOSCH GES., R. Jan. 27, 1940, No. 1688. Convention date, Feb. 9. [Class 102 (i)] [Also in Group XXIX] In a device for automatically adjusting the injection timing of internalcombustion engines wherein one end of a lever engages a collar which causes the cam shaft 2 of the injection pump to be adjusted by angular displacement relative to its driving shaft 34, whilst the other end of the lever is connected to a hydraulic control member in the form of a displaceable wall disposed between two chambers 13, 14 arranged in series in the fuel supply circuit and which are interconnected through a throttle aperture 15 through which varying amounts of the liquid fuel are allowed to pass dependently upon the engine speed, the hydraulically adjustable dividing wall comprises a vane 11 which is combined with the bifurcated lever 18 engaging the collar 21 so as to form therewith a unitary lever of the first order. Pressure in the chamber 13 is maintained uniform by means of an overflow valve 43, whilst the chamber 14 is in communication with the suction chamber 9. The levers 18 on the vane shaft 10 engage pins 19 of a semi-circular shoe 20 which engages in an annular groove in the collar 21. The latter has diametrically opposite internal ridges 22 of a steep thread to engage grooves 32 on a barrel 23 so that longitudinal displacement of the collar causes slight relative angular displacement of the barrel. An internal conical surface on the barrel 23 is locked on a tapered part 24 of the cam shaft 2 by means of a nut 25 and washer 26. Claw-like projections on a coupling member 29 engage in notches 54 in the collar 21 so that the latter is displaceable axially but not angularly relative to the coupling. By these means longitudinal displacement of the collar causes angular displacement of the driving shaft 34 relative to the cam shaft and therefore adjustment of the injection timing. Movement of the collar for advancing the timing at high speeds is opposed by a spring 35. The throttle aperture 15 is formed by a notch in a ring 16 and presents a larger cross-section a for high speeds than that b for low speeds. The ring 16 may be locked in position by a pin 17 or it may be formed with a toothed part on its periphery 55 for engagement by an externally operated adjusting rod.

Abstract: 548,525. Hydrocarbons. STANDARD OIL DEVELOPMENT CO. Feb. 14,1941, No. 2010. Convention date, Dec. 30, 1939. Drawings to Specification. [Class 2 (iii)] In the known catalytic heat treatment in the presence of free hydrogen of hydrocarbons substantially boiling within the gasoline range, in which there is no net consumption of hydrogen or in which hydrogen is liberated, the process is conducted so that recompression of the gases containing hydrogen which are recycled is reduced to a minimum by (a) heating the hydrocarbon oil and gas rich in hydrogen separately before introduction into the reaction zone and (b) passing the products into a fractionator without fall in pressure and without indirect cooling. The following catalytic processes are specified : dehydrogenation, aromatization, cyclization, alkylation and isomerization. Preferably the products leaving the reaction zone are quenched or partly cooled by direct heat exchange with a cooling medium of higher boiling point than the products, e.g. a gas oil, which may circulate through the lower part of the fractionator. Pressures of 50 to 750 pounds per square inch are employed. In an example, the treatment of a heavy naphtha with a gas rich in hydrogen is described, using activated alumina impregnated with molybdenum oxide as catalyst. Two pairs of reaction vessels are advantageous, one pair being used for the reforming process while the catalyst in the other is rejuvenated.
