Title: Process for the production of pure styrene oxide
IPC: C07C17/14
Filed: 1955-10-17
Abstract: Styrene oxide is obtained by treating a finely divided emulsion of styrene in water with chlorine or hypochlorous acid, separating the chlorination product from water, distilling off from the chlorination product the lowerboiling fractions containing predominantly styrene, b -chloro-styrene and styrene dichloride, saponifying the residue containing predominantly styrene chlorohydrin and styrene dichloride with a substance having an alkali reaction, separating the saponification product from the aqueous solution and separating the styrene oxide formed from styrene dichloride by distillation. Preferably the saponification takes place at 60 DEG  to 95 DEG  C. with a solution of an alkali metal hydroxide.  There can also be used as starting material styrene oxide which is substituted one or more times in nucleus or side chain or in both with halogen or an alkyl residue having from one to three carbon atoms.  In the example styrene is mixed with water and isopropyl naphthalene sulphonate as an emulsifier; chlorine is passed in and the mixture is separated in a separating funnel; the nonaqueous layer is distilled so that all substances volatile up to 105 DEG  C. at 12 mm. pass over; this head product is distilled again to give styrene, which is returned to the chlorination stage, p-chloro styrene and styrene dichloride; the residue of the first distillation is treated with caustic soda solution and the crude saponification product is washed with water and distilled to give styrene oxide; as a second fraction there is obtained styrene dichloride which is combined with the styrene dichloride already obtained and converted to styrene chlorhydrin which is supplied to the saponification stage again to give a further quantity of styrene oxide.  Specifications 751,305 and 786,731 are referred to.

Abstract: 638,141. Projection screens. PHILCO CORPORATION. Oct. 4, 1946, No. 29639. Convention date, Oct. 5, 1945. [Class 97 (i)] The reflective surface of a projection screen comprises several specularly reflecting elements of such small size as to be beyond the visual resolving power of an observer at the minimum proper viewing distance, the elements being arranged in contiguous relationship and each element being so shaped that the curves of intersection of its surface with planes which are perpendicular to the general plane of the screen and to an axis of symmetry of the element, are cycloids. The elements which may be elongated in form may be arranged in parallel rows and an element of one row may be arranged in staggered relation to the adjacent element of the adjacent row. In one manner of manufacturing the screen, a row of elements is formed by feeding a sheet 1 of suitable material, e.g. wax, at a uniform rate beneath the circular edge of a cutting tool 6 which is rotated about an axis substantially parallel to the plane of the material in a direction opposite to that in which the material is being moved. The next row of elements is formed in the same manner after the tool has been moved relatively to the work material by an indexing machine. The matrix so formed may be provided with a suitable reflective surface to form a screen directly or from this matrix a press tool or die may be made for the production of screens as by stamping or moulding.

Title: Improvements in the production of black tea concentrates
Inventor: PERECH RAMON
IPC: A23F3/42
Filed: 1955-10-07
Abstract: Black tea concentrate is produced by extracting comminuted unprocessed green tea leaf with steam or boiling water, concentrating the solution by heating at a temperature of 80-90 DEG  C. with exposure to oxygen until 3 to 4% of the solution has been evaporated, this fraction being separated and distilled and then re-mixed with the rest after the latter has been concentrated under vacuum. Potassium permanganate or other inorganic oxidizing catalyst may be used as catalyst.  In Example 1, 100 lbs. unprocessed tea leaf is comminuted, extracted by percolation with steam or boiling water. The solution is oxidized by heating at a temperature of 10 DEG  to 20 DEG  C. below the boiling-point of water exposed to the atmosphere until the extract is satisfactory.  The extract is then evaporated, the first 3 to 4% of the solution distilled off being recovered and returned to the concentrate when evaporation is completed.  According to Example 2, the same process is carried out using 0.03 to 0.06% of potassium permanganate, based on the dry weight of the water-soluble constituents of the solution, as a catalyst.  Specification 839,355 is referred to.

A tractor has a laterally extending arm 9 which carries a downwardly directed shaft 11 furnished with a pad or skid 14 for preventing overturning. The arm 9 is pivotally connected at 10 to a stub shaft 6 rotatable in a bearing 7 (Fig. 4) carried by the wheel hub 5. By rotating the shaft 6 from the position shown in Fig. 2 to the position shown in Fig. 4, a stop portion 6a is moved into a position in which the arm 9 may be lifted to an inoperative position (dot-dash lines). The lifting is effected by rotating a handle 22 which acts on a yoke 17 which straddles the tractor wheel 5. The yoke 17 has a U-shaped portion 18 (viewed end-on in Fig. 2) which engages flats 16 formed on the arm 9. In a modification (Fig. 10), the arms 9 is movable in a horizontal plane by rotation of a handle (Fig. 8, not shown) carried by a rod 25. The handle carries a lever which actuates a locking pin 32 by means of a flexible cable 31. The axis of the rod 25 is inclined slightly to the vertical so as to permit gravity to assist rotation of the arm 9 into its operational position.
