Title: Improvements in or relating to the manufacture of diethyl acetal
Filed: 1946-09-18
Abstract: Diethyl acetal is made by reacting acetaldehyde with ethanol in presence of an acidic catalyst and an inert diluent, which is immiscible with water and which has a distribution coefficient for the acetal in relation to water which is at least double that for the alcohol and aldehyde, in an amount at least sufficient to cause the major proportion of the water in the reaction mixture to separate out as an aqueous phase, intimately mixing the reactants during the reaction, either continuously or intermittently, with the said diluent, separating the two phases formed and recovering the acetal from the diluent phase by distillation.  The acetal may be recovered from the aqueous phase also.  The diluent may be added before or after the reaction has started, and may boil at 120-200 DEG  C.; ethanol or acetaldehyde may be present in excess, e.g. 10-20 per cent excess ethanol.  Catalysts specified are sulphuric and phosphoric acids.  The reaction temperature is preferably below 30 DEG  C.  The process may be carried out continuously in which case the mixing may be effected by turbulence in narrow tubes.  The catalyst is preferably added last after cooling.  Examples describe the reaction of acetaldehyde and ethanol in presence of sulphuric acid, using as diluent: (1) kerosene; (2) benzene; (3) n-hexane; (4) carbon tetrachloride.

Title: Improvements in and relating to rack cutters for cutting internal gears
IPC: B23F21/08
Filed: 1936-10-16
Abstract: 477,568. Gear-cutting. JACKSON & CO., Ltd., P. R., and MONK, I. Oct. 16, 1936, No. 28117. [Classes 83 (ii) and 83 (iii)] In a method of producing a rack cutter for generating straight or helical internal gears, the profile of a number of the internal teeth a is cut out full size on a templet A which is rotated repeatedly through a small angle about the pitch circle centre, while at the same time a cutter templet D is moved in unison tangentially of the gear, the shape of the gear teeth being scribed after each movement of the two templets and the profile of the cutter being developed from the lines so scribed. The templet D slides between fixed supports B, C, and the lower edge is inscribed for a length equal to the pitch projected from a tooth a with, say, five divisions 1 ... 5 coacting with a fixed mark Z. The templet A is similarly provided with markings 1<1>... 5<1> extending over one pitch, projected radially from the pitch circle centre and coacting with a fixed mark Z<1>. In operation, the marks 1 and 1<1> are first aligned with the corresponding marks Z and Z<1> and the profile of the teeth scribed as shown at 1, Fig. 9, on the templet D. The templets A and D are then adjusted until the marks 2 and 2<1> are aligned with setting marks Z, Z<1> and a similar scribing 2 is made. This process is repeated for each of the markings, giving the other scribings shown in Fig. 9. The inner lines are then developed to obtain the required cutting profile as shown cross hatched in Fig. 9, and the rack cutter finished by the usual methods to this profile. The cutter E is then mounted in a relieving tool box on a slide H, Fig. 10, to generate the internal gear G in the usual way. For cutting double helical internal gears, two rack cutters are used and have their teeth inclined to give the desired helical angle.
