Filed: 1928-05-18
Abstract: 293,789. Mattan, C. J., (Assignee of Andrea, O. d', and Doglio, P.). July 12, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Spray carburettors.-The air and fuel are controlled simultaneously by the rotation of a single barrel throttle valve and the fuel valve may be independently actuated, e.g. at starting or to vary the mixture strength, from the dashboard. The body 1 has an air inlet 2 and mixture outlet 3 and contains a rotatable valve 14 having a Venturi bore 15 the spindle 13 of the valve passing through a cover 12 and being actuated by an arm 16. Coaxial with the valve is a jet tube 6 having outlet apertures 17, fuel being supplied to this tube from a connection 10 through a filter 11 and apertures 8. Within the tube is a fuel control valve loaded by an adjustable spring 35 and con,prising a triangular guiding portion 29, Fig. 3, a conical portion 32 and a screwed part 34 carrying a head 33 provided with lugs 20. Around the jet tube 6 is a sleeve 22 formed integrally with a cam 25 adapted to contact with a pin 27. Rotation of the valve 14 to open the air passage therefore imparts an axial movement to the sleeve 22 which, engaging the lugs 20, causes the fuel valve to rise. The cam is rotated by a radially projecting pin thereon engaging a slot in the valve 14. The pin 27 bears against a spindle-shaped body 42 - - 45, Fig. 4, adapted to slide in a tube 3S and to be adjusted bv a lever 49 near the driver. The body is attached by a cable 40 to a piston 46 attached to a rod 48 at the free end of which the lever is mounted, a spring 50 effecting the return movement. A sleeve 51 adjustable by a, collar 52 has an inclined end bearing against a shoulder on the rod 48 and serves to effect fine adjustments. At high engine speeds air enters at 54, Fig. 1, and raises the. cam 25 and the fuel valve thus giving an increased fuel supply.

Patent GB-803401-A (GB)
Title: Thiaxanthene derivatives
IPC: C07D337/12
Filed: 1956-05-11
Abstract: The invention comprises: (a) thiaxanthenes of the general formula <FORM:0803401/IV (b)/1> wherein X represents hydrogen, chlorine or bromine and X1 chlorine or bromine; (b) non-toxic acid addition salts of compounds (a); (c) the preparation of compounds (a) by reacting a thiaxanthene having a chlorine or bromine substituent in one or both aromatic rings with an alkali metal alkyl or aryl and reacting the resulting alkali metal derivative of the thiaxanthene with a 3-dimethylaminopropylhalide; (d) the combination of process (c) with the preparation of the starting materials therefor by reacting a 2-halobenzoic acid or an alkali metal salt thereof with an alkali metal salt of a chloro- or bromo-thiophenol in the presence of a copper catalyst (and preferably also an acid-binding agent) to produce a 2-carboxydiphenyl sulphide having one or two halogen substituents, cyclizing this compound with a dehydrating agent to form a thiaxanthone, reducing this with an alkali metal borohydride, disproportionating the resulting thiaxanthydrol with a hydrogen halide to form a mixture of thiaxanthene and thiaxanthone and isolating the former; (e) the conversion of the products of (c) into salts by reaction with an acid (e.g. hydrochloric, hydrobromic, sulphuric, phosphoric, acetic or benzoic acid).  The products are useful therapeutically on account of their anti-emetic properties. In examples: (1) 2-iodobenzoic is heated with the sodium salt of 4-chlorothiophenol in the presence of potassium carbonate and copper powder to produce 2-carboxy-41-chlorodiphenyl sulphide (on acidification), this is warmed with conc. H2SO4 and the resulting 2-chlorothiaxanthone reduced with KBH4 to 2-chlorothiaxanthydrol, which on refluxing with a solution of dry HCl in absolute alcohol yields a mixture of 2-chlorothiaxanthene and 2-chlorothiaxanthone, these are separated by fractional distillation and the former reacted with butyl lithium in absolute ether and then with 3-dimethylaminopropyl chloride to produce 2 - chloro - 10 - (3 - dimethylaminopropyl) - thiaxanthene, which is converted into its hydrobromide; (2) 4-bromothiophenol similarly yields the corresponding bromo-compounds; (3) the 2-iodobenzoic acid in (1) is replaced by 2-iodo-5-chlorobenzoic acid to produce successively 2-carboxy-4:41-dichlorodiphenyl sulphide, 2:8-dichloro - thiaxanthone, -thiaxanthydrol and -thiaxanthene, and 2:8 - dichloro - 10 - (3 - dimethylaminopropyl) - thiaxanthene.  Alternative reagents for the various steps are listed.

Patent GB-496490-A (GB)
Title: Improvements relating to the waterproofing of textile fibres, fabrics and the like
IPC: D06M11/38
Filed: 1937-05-28
Abstract: Textile fibres and fabrics are rendered water-proof by bringing an amphoteric protein such as casein and a compound containing an amphoteric metal such as zinc or aluminium into contact on the textile and establishing definite acid conditions therein, whereby the amphoteric constituents are caused to combine.  The process may be carried out by impregnating the material with a solution of the protein in an alkaline medium, and then treating with the metal compound.  The acid may be applied together with the metal compound, e.g. by applying it in acid solution, or subsequently, e.g. by immersing the material in an acid bath or treating with a volatile acid.  Alternatively, the protein and metal compound are applied together in an alkaline medium and the impregnated material treated with acid.  In another method, there is applied separately or together with the protein, metal compound or both, a substance which develops acidity on heating, e.g. ammonium or pyridine salts of organic acids such as acetic or oxalic acids. Soaps, fats or waxes may be emulsified in the alkaline protein solution and stored in concentrated form.  In examples: (1) fabrics are padded through an aqueous solution containing casein, caustic soda and sodium aluminate and thereafter are acidified by exposure to the air, carbon dioxide, or steam containing acetic or formic acid; (2) the fabric is treated first with an aqueous solution of casein and borax and then with a solution of zinc acetate; (3) oleic acid and hard paraffin scale are treated with caustic soda and casein and borax added to form a cream. Fabrics are treated first in the warm diluted cream and then in aluminium acetate solution; (4) tallow fatty acids are mixed with paraffin scale and saponified with caustic potash, and casein, borax and sodium aluminate added.  The goods are padded first through the emulsion diluted with water and then through a solution of acetic or formic acid; (5) the goods are padded in an aqueous composition containing casein, borax, soap flakes, sodium aluminate and ammonium or pyridine oxalate and sharply dried.

Title: Improvements in or relating to the permanent setting of fabrics containing or consisting of keratin fibres
Inventor: SPEAKMAN JOHN BAMBER
IPC: D06M13/338
Filed: 1954-05-21
Abstract: A process for the permanent setting of keratin-containing fabrics comprises steaming the fabric, in the form in which it is to be set, in the presence of an agent which is volatile in steam and which is capable of aiding the breakdown of the disulphide bonds of the keratin-containing material, followed by further steaming in the presence of the volatile agent, during which further steaming the volatile agent diminishes in concentration or disappears because of dilution or evaporation by the steam.  The agent used may be ammonia, cyclohexylamine, trimethylamine, ethylamine or ethylene diamine or carbonates of these bases, hydrazine, hydrazine hydrate, ammonium bisulphite or sulphurous acid.  Sodium bisulphite may also be used, but in this modification of the invention the residual base must be removed by washing.  The treatment may be accomplished in one of the three following ways:-(i) the fabric is placed on a plane sheet of pleating paper and dusted with a powdered volatile base such as ammonium carbonate; it is then covered with a further sheet of pleating paper, pleated in the desired manner, and steamed until all volatile material has escaped; (ii) the fabric is pleated as before, the volatile base being introduced into the steam during the early stages of steaming; (iii) the fabric is treated with a solution of sulphur dioxide or of a bisulphite after which it is rinsed, pleated and steamed as before.  If desired, the steaming process may be carried out on the roller of a blowing machine. The pleats are said to be substantially unaffected by wetting or by dry-cleaning. Examples and experimental results are given.
