Patent GB-455087-A (GB)
Title: Improvements in or relating to the manufacture of polymerisable compounds
IPC: C07C51/08
Filed: 1935-03-13
Abstract: Acrylic acid is manufactured by hydrolyzing ethylene cyanhydrin with sulphuric acid diluted with water.  The reaction may be effected by distilling the mixture of the cyanhydrin and acid, preferably with the passage of carbon dioxide through or over the liquid, which passage may be commenced as soon as acrylic acid commences to distil over or prior to heating.  Further ethylene cyanhydrin may be added at approximately the rate at which the acrylic acid distils over.  In an example, ethylene cyanhydrin is distilled with three times its volume of a dilute sulphuric acid obtained by diluting 98 per cent sulphuric acid with one-fifth its volume of water.  The crude distillate is purified by distillation at 20 mm. pressure in an inert atmosphere, e.g. carbon dioxide, or by allowing crystals of acrylic acid to deposit from the liquid.

As shown, the sealing-means comprises soft rubber rings 2, 2<a> housed in auxiliary vacuum chambers 1, 1<a> below and above the main chamber 3 which rings are contractible for the positioning of a tyre band 9 by vacuum applied through pipes 5, 4 connected through a valve box 7 to a vacuum line 8. The box 7 is fitted with a valve controlling vacuum to the pipe 6 connected to the main chamber 3, and vacuum and atmospheric valves for the pipes 4 and 5, the three valves being actuated by cams 21, 20, 19 on a shaft 17 operable by a handle 18<a>. In operation, the rings 2, 2<a> are contracted by the application of vacuum and the casing 9 is introduced and centred upon an adjustable support 10, after which the rings are allowed to contract to engage the tyre and the latter shaped by application of vacuum to the main chamber. The rings 2, 2<a> are formed with sealing-lips 15, Fig. 5, and may be retained within their chambers by chains. The rings may be formed in sections.

Abstract: 675,950. Pressure gauges; indicating-apparatus. WALLACE & TIERNAN PRODUCTS, Inc. Feb. 19, 1948 [March 15, 1947], No. 8023/51. Divided out of 643,910/48. Classes 106(ii) and 106(iv). Pressure-sensitive apparatus comprises a " bellows " 11 (defined as a box having one or more flexible or flexibly mounted walls movable in accordance with pressure changes) communicating with a second bellows 51 and a relief means including a valve which is operated by the second bellows in response to a predetermined abnormal pressure difference between the interior and exterior of the pair of bellows. As shown, a conduit 60 supplies fluid pressure to the interior of capsules 11, 51 having annularly corrugated walls. The relief valve comprises a passage 65 crossing the conduit and closed at each end by a spring arm 73 or 76 carrying a resilient closure disc 75 or 78. The arms are operated to open the valve by parts of a rod 80 carried on one wall of the capsule 51. The conduit has a restricted portion (not shown) to prevent buildup of pressures in the capsules in spite of the valve. The capsules are connected by a rigid conduit 14 which is supported by a clamp 16 and cross-bar 54 fastened to a base 10. The capsule 11 carries a rod 18 connected to a pivoted lever 20 having a gear segment 21 meshing with a pinion 22 on a pointer shaft 23. The lever pivot comprises leaf-springs 30, Fig. 2, engaging slots in a cross-member 28 secured to the lever, and in a fixed bracket 26. The rod 18 has a flexible part 35 and a transverse arm 34 adjustably clamped to the member 28. Backlash in the gearing 21, 22 is prevented by a spring 41 on the segment connected to a filament 40 wound around a drum on the shaft 23. The tension of the capsule 11 can be altered by an angularly adjustable arm 44 and spring 45.

Abstract: 1,075,044. Gun-Sights. FMC CORPORATION. Feb. 28, 1966 [March 1, 1965], No. 8760/66. Heading F3C. A gun-sight for a gun G which is mounted for training and elevation in trunnion supports 14 on a hollow pedestal 12 comprises a periscope tube 24 fixedly and coaxially positioned within the hollow pedestal 12, upper and lower azimuth mirrors A1, A and an elevation mirror E. An optical means, e.g. a dove, K- or pechon prism, is located in a rotatable sleeve 32 in the periscope tube 24 for rotation by the gun such that the image of the target is erect independent of the training or elevation of the gun. The upper azimuth mirror A1 and the elevation mirror E are mounted on a shaft 30 extending through one of the trunnion supports 14 such that azimuthal rotation of the trunnion supports causes the mirrors to rotate bodily about the axis of the periscope tube 24. A linkage L rotates shaft 30 to turn the elevation mirror E in elevation. The optical means, i.e. a prism, is driven at half speed with respect to the rotations of the gun in azimuth and elevation by means of interrelated gear trains 26, 28, 34. The gun is manually driven in azimuth by rotating the trunnion supports and is manually elevated through a rack-and-pinion, the rack being urged in a vertical direction by a rotary motion which is translated by an internal epicyclic gear (Figs. 6 and 9, not shown) into linear motion of an elevating tube and a rotatably mounted intermediate gun elevating sleeve. The gun is mounted on a military vehicle (Figs. 1 to 3, not shown), and the breech end of the gun may be lowered into the vehicle by first elevating the gun to a vertical position and then lowering the whole assembly on its carriage.
