Title: Process for the manufacture of phosphorous pentafluoride
Inventor: WIESBOECK ROBERT ALFRED
IPC: C01B25/10
Filed: 1970-03-10
Abstract: 1287202 Phosphorous pentafluoride; phosphoryl fluoride-sulphur trioxide complex USS ENGS & CONSULTANTS Inc 10 March 1970 11527/70 Heading C1A Phosphorous pentafluoride is produced by reacting POF 3  with SO 3  to form an adduct (POF 3 .SO 3 ) which reacts with hydrogen fluoride to form PF 5  and sulphuric acid. The invention includes a liquid reaction product of SO 3  and POF 3  which comprises a POF 3 .SO 3  adduct and the new compound phosphoryl fluoride-sulphur trioxide (POF 3 .SO 3 ) per se. It is advantageous to mix POF 3  with liquid SO 3  at reduced temperatures and to allow the mixture to warm to room temperature before further reaction with HF at a reduced pressure. In an example an evacuated reactor was cooled to - 196‹ C. and charged with SO 3  (10À0 g.) and POF 3  (13À3 g.). On warming to room temperature a pressure of 200 p.s.i. developed temporarily. The resulting slurry was stirred to dissolve all the SO 3  resulting in a clear colourless liquid. This liquid was transferred to an evacuated aluminium cylinder (250 c.c.) containing HF (6À8 g.) at - 40‹ C. A pressure of 50 p.s.i. developed and the cylinder was slowly warmed to 60‹ C. After 1 hour the cylinder was cooled to 25‹ C. and PF 5  (81% yield) vented into cold trap maintained at - 196‹ C. with liquid nitrogen.

Title: Improvements in and relating to the moulding of parts of irregular shape
IPC: B22C9/10
Filed: 1943-07-19
Abstract: 571,473. Moulding magnetic dust cores &c. ACES DEVELOPMENT CO., Ltd., and FRIEDLAENDER, E. R. July 19, 1943, No. 11687. [Class 87 (ii)] In order to obtain an article having uniform density throughout, the stationary die 3 is surrounded by a movable mould 6 which is based upon a pneumatic cushion. The mould 6 rests on a carrier 2 which is supported on a pneumatic ram 8 which slides in a ram stop 8a in a vessel 9. The die 3 is held in position by a key 4 passing through a slot therein. In operation, the vessel 9 is filled with air or gas at a pressure which gives a thrust P which is less than the maximum thrust P<2> which will be exerted by the plunger 7, and the mould 6 is filled with powder or preformed pellets. The plunger 7 descends and the mould 6 descends relatively to the die 3 (the ram 8 being forced down) until the pressure built up in the vessel 9 gives an upward thrust which equals the thrust on the plunger. When the pressure on the plunger is released, the parts 8, 2, 6 rise to the position shown and the mould 6 is replaced by an empty mould. The die 3 may pass through the cushion and may be actuated by a cam to eject the moulded article. By altering the distance A, the volume of the moulding space M can be altered. Specification 550,577 is referred to. The Provisional Specification refers to the manufacture of screw type magnetic powder cores.

Title: An improved process for producing photographic papers for making prints from tracings
IPC: G03C1/66
Filed: 1926-05-07
Abstract: 252,012. Kammerer, H. May 7, 1925, [Convention date]. Papers; developing; bichromated colloid.- Paper for producing prints from tracings is prepared by coating it with a solution containing a chromate or bichromate and organic salts of heavy metals such as iron to which may be added one or more salts of manganese. The ferric salts of citric, oxalic, or tartaric acids are especially suitable. After exposure development is effected with aromatic amines, phenols or amidophenols, which may be acidified, or with there derivatives or substitution products. The developer may however be applied dry or in solution to the paper before exposure, in which case development is effected after exposure by applying a damp sponge, or by treatment with steam. Baryta paper may be used as a base for the coating. Prints in different colours may be obtained by choice of developer. An example is described in which a coating containing bichromate and ferric ammonium citrate is exposed and developed with a solution of aniline hydrochloride; or, alternatively is moistened before exposure with a solution of aniline, and developed after exposure with a damp sponge or steam. The sensitizing solution may be used in the preparation of gum bichromate papers.
Patent GB-578763-A (GB)
Title: Improvements in or relating to fluid-solid contact-surfaces
IPC: B64C21/06
Filed: 1942-08-25
Abstract: 578,763. Reducing surface friction between a solid and a fluid. GRIFFITH, A. A. Aug. 25, 1942, No. 11973. [Class 4] To improve the effect of slots provided for the removal by suction of the boundary layer of fluid from surfaces such as those of aeroplanes, pumps, compressors and turbines, that are movable relatively to the fluid, the surface is so shaped that no rise of pressure occurs on the surface in the general direction of flow except in the region between a slot and its associated stagnation point where the flow of the boundary layer is locally reversed in direction. This may be done by providing that the surface curvature suddenly changes in passing across the slot so that it is less convex on the downstream side of the slot. In the example shown, the parts 23, 24 of the surface on the upstream and downstream side of a slot 13 are convex and concave respectively and the slot is tangential to the curve 24. There is thus no rise of pressure except as shown by the pressure curve P at 19, between the slot and the stagnation point 18 and the pressure falls gradually as indicated at 25, from the stagnation point to the next slot downstream. A fan 26 is provided for producing suction in the slots. With a surface and slots so formed and arranged, there is no fall and subsequent rise of pressure between the stagnation point and the next slot such as is shown to exist with the usual slotted surface. In a modification, the slots are wider than is necessary for the removal of the boundary layer and there is a sharp edge between the convex surface 23 and the upper flat wall of the slot.
