Title: Improvements in and relating to capsule sealing machines
IPC: B67B3/10
Filed: 1940-01-17
Abstract: 537,087. Capsule sealing apparatus. CARTNER. J., BENNETT, H. J., and SUTCLIFFE, T. Jan. 17, 1940, No. 1034. [Classes 125 (ii) and 125 (iii)] A capsule sealing machine has an endless contractible spring 18 to turn the capsule flange beneath the shoulder of the container ; the spring is formed of rectangular material and the edges 20 shown in Fig. 3, are ground away to ensure an accurate cylindrical surface to the spring. The arms 4, 5 are pivoted in lugs 2, 3 on the frame 1, and carry cylindrical lugs 13, 14 which when the handles are depressed cause the plunger 11 to be depressed relative to the conical surface 16 on the frame 1. This causes the ring 18 to move inwards and contract to seal the capsule flange. The surface 16 may be convex or concave. In a modification the spring is of the form shown in Fig. 5, and has rollers 22 with recesses 23 to accommodate the small springs 24 which hold the individual rollers apart when they are assembled in ring formation.
Patent GB-764629-A (GB)
Title: Improvements in or relating to process for recovery of glutamic acid
IPC: C07C227/28
Filed: 1955-01-13
Abstract: Glutamic acid is obtained from thin Steffen's filtrate of pH 9.5-10.5 by storing it at an elevated temperature for at least 24 hours, directly concentrating to a dry content of 55-80 per cent and separating glutamic acid from the resulting hydrolysate. Calcium glutamate separates out during the concentration but redissolves on neutralizing or adding water.  Glutamic acid can be recovered from the solution by adding a reagent such as carbon dioxide, sulphur dioxide or sodium carbonate to precipitate the calcium, filtering and crystallizing glutamic acid from the filtrate at pH 2.5-3.5; impurities may be precipitated at pH 4.5-5.5 before the final acidification.  Alternatively the neutralized concentrate (pH 9.0-9.5) is treated with methanol to precipitate calcium glutamate; this is dissolved in water, the calcium precipitated and glutamic acid crystallized as above. Preferred conditions are storage at 55-95 DEG  C. for up to 48-72 hours (or even up to 120 hours) and concentration to dry content of 65-75 per cent at a temperature between 50 DEG  C. and reflux, e.g. 50-70 DEG  C. in vacuo.  Examples are given of the process.

Abstract: 1,076,451. Modulating light. KOLLSMAN INSTRUMENT CORPORATION. Jan. 12, 1965 [Feb. 13, 1964], No. 1401/65. Heading H4F. [Also in Divisions G1, G2 and G4] Incident light 153 impinging on an internal surface 151 of a prism 152 at an angle greater than the critical angle is normally reflected at 154 but by placing a structure 150, comprising a plurality of independently movable elements, adjacent to surface 151 and moving one or more of such elements into substantial contact with the surface 151 so that at that position or positions the light is not internally reflected, the pattern of light in the exit beam 154 may be controlled as desired. To frustrate internal reflection the element should be within a tenth of a wavelength of surface 151 and beyond a distance of one wavelength the element has no effect. A mosaic of magnetostrictive or piezoelectric bodies, Figs. 3, 7, 7b, 8, 8a (not shown), may form the frustrator elements themselves or may control such elements or a single sheet (60), Fig. 4 (not shown) of magnetostrictive material may have a grid of conductors 61-70 which divide the sheet 60 into areas which may be deformed to vary their distance from an adjacent reflecting surface. The arrangement may be used in a projection system, Fig. 10 (not shown). In another application, a linear instrument dial (197), Figs. 12, 13 (not shown), is formed as the output surface of a prism (183) whose input surface is illuminated by lamps (200), a frustrator assembly (183a) being placed closely adjacent the hypotenuse reflecting surface (184). Normally, the assembly (183a) prevents reflection of light at surface (184) but on actuating the appropriate element of assembly (183a) light is reflected at the desired position towards the front viewing surface (197). In a modification for a circular scale, Fig. 11 (not shown), the prism (171) is of annular form.
