Title: Improvements relating to the prevention of back-firing in two stroke internal combustion engines
IPC: F02M1/00
Filed: 1926-03-10
Abstract: 260,840. Fornaca, G. March 10, 1926. Induction pipes, fittings for; pumps, rotary.- In two-stroke engines fed by a compressor between the carburettor and the cylinders, backfiring, due to reduction in pressure in the mixture supply pipe consequent upon sudden closing of the throttle valve, is prevented by providing an automatic air inlet valve on the conduit between the carburettor and the compressor. The cylinder 1 has exhaust ports 6 and inlet ports 7 and is fed through a pipe 8 by a compressor 9 which draws mixture from a carburettor 10 provided with a throttle valve 12. On the conduit 11 between the compressor and the carburettor, an inwardly opening automatic valve 13 is fitted adjustably loaded by a spring 14 and nuts 15, 16. If, with the engine running at high speed, the throttle is suddenly closed or partly closed, the reduction in pressure in conduit 11 causes valve 13 to open and admit air, which maintains the pressure in pipe 8 sufficiently high to prevent back-firing.

Title: Improvements in or relating to the manufacture of mono-chloroisobutyric acids
IPC: C07C53/19
Filed: 1935-03-04
Abstract: Monochlorisobutyric acids are made by chlorinating isobutyric acid up to but not beyond the point at which no isobutyric acid remains, in the presence of a suitable chlorinating catalyst such as sulphur, chlorides of sulphur or phosphorus, or inorganic and organic acid halides and anhydrides such as sulphuryl chloride, thionyl chloride, sulphur trioxide, oxides of phosphorus, chlorides and anhydrides of acetic, propionic, butyric, and benzoic acids.  Preferably, sulphur is employed in quantity not exceeding 4 per cent of the reaction mixture.  The point at which to stop the chlorination is advantageously estimated by measuring the specific gravity of the liquid.  To obtain a -chlorisobutyric acid the chlorination is effected above 115 DEG  C. with 2--4 per cent of sulphur; for the b -acid 0,5--2 per cent of sulphur may be used at a temperature below 115 DEG  C. such as 70 DEG  C.  In examples, sulphur, isobutyryl chloride and thionyl chloride are used as catalysts, the last two in much larger quantities than the sulphur.  Specification 428,223 is referred to.
