Patent GB-829058-A (GB)
Title: Improvements in or relating to a process for separating into its constituents an aqueous mixture of a lower aliphatic alcohol, a lower monocarboxylic acid and the ester thereof with the lower aliphatic alcohol
IPC: C07C51/09
Filed: 1958-02-25
Abstract: <PICT:0829058/III/1> A process for separating a mixture of water, a lower aliphatic alcohol, acetic acid and the ester of said alcohol and said acid comprises distilling the mixture in a functionally single column, the upper portion of which operates an extractive distillation in the presence of added water, withdrawing from lateral points of said column alcohol-free ester, and aqueous alcohol containing a minor amount of said ester, and withdrawing anhydrous acetic acid from the base of the column.  In a preferred embodiment applied to the separation of methanol, methyl acetate and acetic acid obtained by the hydrolysis of methyl acetate with water which is effected in a reactor 1, the mixture passes into a distilling column 3 which is heated sufficiently to obtain anhydrous acetic acid from the base by pipe 4.  The vapours leaving the top of column 3 are fed to the bottom of column 31, the bottoms of which is divided into two portions one of which is refluxed to the top of column 3 by a pipe 6 while the other is introduced into a column 11 by a pipe 7. Unchanged methyl acetate is withdrawn from column 31 by means of an internal decanting plate 8 and is recycled to reactor 1 by pipe 10, additional methyl acetate being fed in at a line 14.  Water and methanol are withdrawn through a pipe 13 from the base of column 11 which is so heated as to return the methyl acetate to column 31 by a pipe 12.  Hydrolysis of the ester can be assisted by the use as catalyst of an inorganic acid or a cation-exchange resin such as a sulphonic polystyrene resin.  The process may also be applied to the separation of the hydrolysis products of ethyl acetate or isopropyl acetate. Specification 687,902 is referred to.

Title: Improvements in or relating to film feed control systems for optical projectors and photographic cameras
IPC: G03B21/00
Filed: 1948-02-27
Abstract: 703,472. Optical-projection apparatus. SANSONE, C. Feb. 27, 1948 [Oct. 11, 1944], No. 6164/48. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 27, 1948.] Class 97(1) A projector similar to a kinematograph projector is combined with a counter device of the kind described in Specification 665,608, [Group XIX], to enable any particular film frame to be selected for projection by setting the counter. The counter 32, as shown, records the turns of a shaft 34 which may be engaged, by a clutch actuated by a knob 40, to be driven by a sprocket 44 from the motor 33 in synchronism with the film driving shaft 35 of the projector. The counter thus registers the passage of film frames and is arranged to switch off the motor 33 when the selected frame is reached. The shaft 34 may, alternatively, be clutched to a ratchet wheel rotated each time a feeler 41 drops into a notch 42 in the film margin so that the counter records the number of notches. The film frames may be classified in accordance with different criteria and film notches of different depths or opposite margins provided, together with appropriate feelers for sensing them. The projector may have a light-tight film path to allow use of the apparatus as a camera. The Specification as open to inspection under Sect. 91, in connection with Specification 665,608 also comprises a number of other embodiments which do not admit of satisfactory detailed abridgment. These embodiments appear, however, to include combinations of projectors, such as described above, which can be controlled individually or for the counter device provided on one of them. In another arrangement the counter device can apparently be used to control not only the film feed but also the rotation of a lens turret to change the degree of magnification of the image, as well as lateral and vertical movements of a screen to select the area on which the image is projected. The controlling dial on a projector as described above may apparently be separated from the projector with electrical connection to it. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in processes for precision castings
Inventor: COLCLOUGH HAROLD
IPC: B22C9/04
Filed: 1950-03-17
Abstract: 678,035. Moulding processes; mould materials. ROLLS-ROYCE, Ltd. March 16, 1951 [March 17, 1950], No. 6777/50. Class 83 (i). [Also in Group V] In a method for the precision casting of hollow articles, more particularly blades for internal combustion turbines made of a high melting-point metal, an insert of fired waterbound clay refractory is first supported in a die while a wax pattern is formed around it and is then supported in a flask, while the pattern is invested by the refractory mould material so that after melting out the wax, the insert remains as a part of the mould and after casting the article, may be removed therefrom by mechanical means. The insert is cast in a two-part plaster of Paris mould a, a<SP>1</SP> Fig. 1, having a filling opening d and an internal cavity with a central part c and end portions c<SP>1</SP> to form projections e on the insert. A suitable refractory for forming the insert comprises bentonite 1-5 per cent, pipe clay 1-10 per cent, china clay 10-60 per cent, flint powder 10-60 per cent, molochite 5-50 per cent, sodium carbonate less than 1 per cent, sodium silicate less than 1 per cent and water as required. Another suitable refractory comprises ball clay 4.5-5.5 per cent, pipe clay 11-12 per cent, china clay 15-17.5 per cent, flint powder 30-40 per cent, sodium silicate and sodium carbonate 0.125-0.250 per cent and water 26-35 per cent. Before the refractory has completely set, the mould may be inverted to allow some of the material to run out from the centre, thus leaving a hollow insert which is fired at up to 1000‹ C. The insert is then supported in a two-part die by its end projections while wax is injected to form the pattern around the insert. The insert is then supported at one end in a wax block g, Fig. 3, on the base h<SP>1</SP> of a flask h, a block of wax g<SP>1</SP> being inserted between the block g and the pattern f<SP>4</SP> in order to support the latter and to form a runner when the wax is melted out. The pattern and insert are invested with the mould material from a funnel j, and the wax melted out to leave the insert as part of the mould. After casting, the mould is broken away from the article and the insert destroyed as by sand-blasting.
