Abstract: 1,031,379. Cathode-ray oscilloscopes; radar. FERRANTI Ltd. June 24, 1963 [June 29, 1962], No. 24966/62. Headings H4D and H4T. In a mobile navigation system incorporating a P.P.I. radar display cathode-ray tube (C.R.T.) 11, Fig. 1, and a map display 13, an optical system provides an image at or near infinity of the two displays superimposed in register with one another, arrangements being provided for projecting display 13 on to the screen of C.R.T. 11 and for forming the image from the composite display. To equalize image brightness, a mirror 14 is made more reflective than transmissive or may be dichroic; to enhance contrast a filter 21 of colour complementary to that of the phosphor on the C.R.T. is added; for inhibiting reflections from the outer surface of a collimating lens 16 a polarizing filter 22 is utilized; and the front surface of the glass face of the C.R.T. may be bloomed. An image of further data may be added. In another arrangement, Fig. 2, no partially-transmissive mirror is used. The C.R.T. display may be of the true-motion kind, the map display being likewise compensated for craft movement.

Patent GB-673703-A (GB)
Title: Method of purifying streptomycin
IPC: C07H15/238
Filed: 1949-10-03
Abstract: Histamine-like impurities are removed from an aqueous solution of streptomycin by the action of bromine or of hypochlorous acid (which may be liberated in situ from sodium hypochlorite), e.g. by treatment therewith at about 20-25 DEG  C. followed by standing, preferably at a low temperature, and removal of the sediment which settles out. The treatment is preferably effected at a pH below 7 (e.g. initially 5.7), but when using bromine (of which an excess is advantageously employed and subsequently removed) it is possible to start with a neutral solution and rely on liberated hydrobromic acid for acidification.  In examples: (1) an aqueous solution of streptomycin is prepared from a Streptomyces griseus fermentation broth by adsorbing the streptomycin on silica gel, eluting with dilute acid (e.g. hydrochloric acid), neutralizing, adsorbing on activated carbon, eluting with acidified aqueous acetone, again neutralizing, concentrating, and, if desired, acidifying to pH 5.7, and is treated with excess of bromine water and then neutralized with caustic soda, excess bromine is extracted with chloroform, the solution is allowed to stand at 5 DEG  C., and the sediment is removed; (2) the starting material of (1) is agitated with a solution of bromine in chloroform, which is then removed and the process completed as in (1); (3) the process of (1) or (2) is varied by effecting the adsorption on and elution from activated carbon after the treatment with bromine.

Abstract: 334,060. Heide, H. C., (Cincinnati Bick ford Tool Co.). Aug. 23, 1929. Reversing-gearing ; friction clutches.- Reversing-gear, for radial drills and other precision machine tools, wherein a bevel wheel on the driving, or driven, shaft engages two bevel wheels selectively put into driving engagement with the driven shaft through multiple-disc friction clutches, comprises a splined driving-shaft 2, indicated by broken lines in Fig. 1, upon which is mounted a sleeve 3 splined only near the end x at which the drive is instituted. Bevel wheels 8, 9 are attached respectively to clutch elements a, b which have sleeves 13<x> rotatably journaled on a bushing 11 splined to the sleeve 3 and preferably made in two parts as shown. The sleeve parts 13<x> are separated by a washer 26 which is replaceable by thinner washers to compensate for wear in the bevels. Each clutch element c carries, in radial bores, studs 15 which engage notches in the driving-discs, and has a sleeve portion # splinded to the sleeve 3. Splined to the sleeve # is a member g carrying clutchoperating levers 21 held in the retracted position by spring-loaded plungers 22, and operating on the presser ring 17. In order to take up wear, the member g can be adjusted towards the clutch by means of a nut 23, accidental rotation of which is prevented by spring detents 25 engaging notches in the nut. Outward movement of the clutch members a and b is limited by spacer members 27. The clutch levers are operated by cam surfaces h, i on bars 28 slidingly fitted in key ways in the sleeve 3 and having heads 28<h> carried within an annular groove in an operating collar 31. The heads 28<h> are admitted into the groove by a portal 32, Figs. 1 and 2. and after assembly are prevented from registering therewith by means of a set-screw 33 which limits relative rotational movement of the collar.

The secondary 37 of the transformer 33 is connected to one coil of a ." left/right " indicator 40 having its other coil fed from the A.C. supply 5, so that the indicator pointer moves in correspondence with the orientation of the inductor in the earth's field. Alternatively the indicator 40 may be replaced by a two-phase induction motor arranged to orient the inductor in the earth's field. A three-legged inductor with a pick-up coil on each leg may be used with three similar amplifiers to operate a resultant field receiver giving 360 degrees indications (Fig. 2, not shown). The pick-up coils may be connected in star, delta, or opendelta, and two amplifiers may be used instead of three.

Abstract: 631,148. Model railway coaches. JONES, S. S. W. Sept. 25, 1947, No. 26014. [Class 132 (iii)] The side walls of a model railway coach consist of glass strips having a layer of flexible covering material secured thereto, which covering material projects beyond two or more edges of the glass strip and is secured to adjacent members of the coach body. Thus the coach may comprise a pair of roof and floor members, to which are secured a pair of shaped end pieces, and a pair of side walls consisting of glass strips and coverings therefor consisting of flexible material, projecting beyond the edges of the glass strip and secured to the end pieces and/or one or both of the roof and floor members. Preferably the flexible material is wood veneer and window apertures may be cut therein. As shown, the coach body comprises wooden roof and floor members 1 and 2, end pieces 3 and glass side walls 4 covered with wood veneer strips 5 in which there are window apertures 6. The glass strips are held in position by the veneer which projects beyond the glass strip at the ends and along the long edge 7 and is attached to the sides and floor member. The upper edges of the glass and veneer register with the rebated edges 8 of the roof member. Preferably the under edges of the floor member are curved or rounded at 9 and the portion 7 of the veneer strip is glued to this rounded part. During assembly the edges of the end pieces are attached to the roof and floor members with metal pins and/or glue. The two veneer strips are glued to the glass side pieces, parts of which may be frosted, secured to the sides of the end pieces with or without the aid of pins and the projection 7 is softened with water and bent to fit the rounded edges of member 2 and secured with glue. A longitudinal groove 10 of rectangular section is formed near the centre of the floor member and fixed at intervals to the side portions of the floor member, by glue or pins, are wooden blocks 11 representing seat backs and between them thin horizontal wooden pieces 12 representing table tops. These seats hold the glass sides in position making rebated edges in the floor member unnecessary. Wheels, buffers and the like are then added.
