Patent GB-332844-A (GB)
IPC: G10K5/00
Filed: 1929-10-29
Abstract: 332,844. Pilny, A. Oct. 30, 1928, [Convention date]. Copying. - In producing subtractive threecolour kinematograph films, the three component images, arranged on a film, are projected on the front and rear side of a film sensitized on both sides, so that two of the component images are in register and the third may be registered by folding the film longitudinally. In the form shown in Fig. 1, the component images 6a, 6b, 6c, which have been simultaneously recorded on a film 5, are projected by lenses 7 and prisms 9 and 10 on to a, film 14 provided with sensitive layers 11, 12 on both sides, so that the images 6a and 6c are in register at 13a and 13c on opposite sides of the film 14. The latter is folded at rightangles longitudinally so that it receives the third image 6b directly at 13b. The three images 13a, 13b, 13c are then coloured and registered by holding the film 14 down on itself. In a modification, the images 6a, 6b, 6c are projected on to the film 14 which is flat, not folded.

Title: An implement for laying lengths of material in the ground
IPC: E02B11/02

Abstract: 844,269. Drainage. WILLNER, K. Oct. 22, 1957 [Oct. 25, 1956], No. 32902/57. Class 33. [Also in Group XXI] An implement for laying lengths of material beneath the surface of the ground 15, namely, electricity cable, flexible water pipe, tile drains or rubble for drainage purposes by first opening up at least one oblique slit into which the said material 17 is passed and allowing the slit to close at least partly on moving forward, comprises a share 1, 2 fixed to a thickening plough body the outside of which forms a landslide 4, 5 and the inside of which forms a guiding surface 7, 8 to elevate the earth slice 10 to widen the slit. There is at least one passage 11 in the plough body for introducing the material 17 and a projection 13 attached to the bottom of the surface 7, 8 indents the bottom tip of the slice 10. The cutting edge of the share 1, 2 is inclined backwards relative to the lower edge 6, and apertures 16 therein may convey liquid to diminish friction between the soil and surfaces 4, 7, 5 and 8. Into one slit 12 material such as rubble may be introduced through an aperture 37 between the surface 8 and the landslide 5 and guided by a curved plate 38 into an aperture 39 at the plough rear. In a modification, the surface 8 and the landslide 5 are united to form a single plate, whereas, when the slice of earth is cut by cutters in front of the share 1 and 2, the landslide 5 and the upper portion of the edge 2 may be wholly or partly omitted. The plough body may be drawn or pushed by a track-laying tractor, in connection with which a levelling device is used to obtain a slight fall with drainage pipes.

Patent GB-486669-A (GB)
Title: Improvements in or relating to the manufacture of organic acids
IPC: F16G13/06
Filed: 1936-12-08
Abstract: In the production of organic acids by forming an addition compound of a boron-halogen-containing compound and an alcohol or a body which on hydrolysis yields an alcohol, and reacting this addition compound with carbon monoxide, the organic acid is liberated from the reaction product by adding an alkaline earth halide, preferably calcium fluoride.  The boron compound may be boron fluoride, dihydroxy fluoboric acid, hydrofluoboric acid, or the oxygen-containing acids obtained by treating boric acid or borates with hydrogen halides; or boron fluoride containing a small proportion of dihydroxy fluoboric acid or hydrofluoboric acid may be used.  The alcohol may be monohydric and primary, secondary or tertiary through the secondary and tertiary alcohols are less satisfactory.  Polycarboxylic acids may be obtained from polyhydric alcohols such as propylene or decamethylene glycols. Instead of the alcohols there may be used esters, ethers and the like which yield alcohols on hydrolysis.  In this case it is desirable to have enough water present to effect the hydrolysis. The reaction may be effected at pressures from atmospheric to 1000 atmospheres or more and from room temperature up to 350 DEG  C. In examples (1) methanol and boron fluoride are passed into an autoclave and carbon monoxide is injected at 800-900 atmospheres and 250 DEG  C.; the product may be heated to drive off some methyl acetate, and then calcium fluoride is added and the mixture is heated to distil off acetic acid; (2) the addition compound of ethanol and boron fluoride is reacted with carbon monoxide as described above and propionic acid recovered by heating with calcium fluoride.  Specifications 310,438, [Class 2 (iii)], and 478,246 are referred to.  According to the Specification as open to inspection under Sect. 91 the process is not limited to the step of heating the reaction product with an alkaline earth halide.  It is stated that the organic acid may be obtained by distillation of the reaction product.  Thus the product may be heated at 15 mm. pressure which expels 16 per cent of the acetic acid; the pressure is raised to atmospheric or higher and 15 per cent of the boron fluoride is expelled; the pressure is again reduced and more acetic acid is recovered, these operations being repeated.  There is an additional example in which carbon monoxide is reacted with the addition compound of boron fluoride and ethyl ether in a silver-lined autoclave; the propionic acid is recovered by the differential distillation process described above.  This subject-matter does not appear in the Specification as accepted.
