Title: Improvements in and relating to windows
IPC: E06B3/10
Filed: 1945-03-08
Abstract: 588,804. Windows. BRAYBROOK, V. W. March 8, 1945, No. 5754. [Class 20 (iii)] In a window having a casement sash, the rails and stiles of the casement are formed by main members 11 and inner members 12 fitted around the inner perimeter of the main members, the main members 11 resting in the normal position against the external face of the frame members 1, 2, 3 and the inner members 12 being partly inset in the plane of the casement sash so that they are set inwards from the external face of the members 11 to form a rebate therewith for the glass 15 and to enter a rebate 10 formed in the window frame. To prevent warping the members 11, 12 are arranged so that they tend to warp in directions perpendicular to one another, and the dimension of the member 12 at right angles to the plane of the glass is therefore preferably made the same as the dimension of the member 12 parallel with the plane of the glass, so that both may be cut from similar pieces of timber of equal thickness. As shown in Fig. 7, the window may be double glazed, the inner pane for the casement sash being held in place by the removable fillet 24 forming the inward setting part of the inner member 12. The window may be formed with some of the rails and stiles of the form described and some of the ordinary type.

Title: An improved temperature-compensated spring
IPC: C22C9/04
Filed: 1955-02-25
Abstract: 801,314. Making springs; altering physical structure. STRAUMANN, R., STRAUMANN, F., and KRUGER, G. Feb. 25, 1955 [Feb. 26, 1954], No. 5780/55. Drawings to Specification. Classes 83 (2) and 83 (4). [Also in Group XXXII] A non-ferromagnetic temperature-compensated spring is made of a material, e.g. beta brass, pyrex glass or K-Na tartrate, which is selected for its ability to undergo a homomorphous transformation, and further selected so that, as a result of such a transformation ability, it will exhibit, within the operating temperature range, an anomaly of the modulus of elasticity such that a minimum value, in the neighbourhood of zero, is obtained for the thermo-elastic coefficient. The effect of this anomaly is that, by subjecting the non-ferromagnetic material to treatments, e.g. rolling, tempering or other heat treatment, the thermoelastic coefficient can be kept very small within the temperature range in which the spring has to operate. Among such homomorphous transformations are an ordering process, conversion from the anti-ferromagnetic state into the ferromagnetic state and the conversion from the non- ferroelectric state to the ferroelectric state.

Title: Improvements in or relating to the recovery of streptomycin
Filed: 1947-03-07
Abstract: The adsorption and elution efficiencies of activated carbon employed in the concentration and recovery of streptomycin are improved by treating the carbon with the acid sulphuric ester of a saturated aliphatic alcohol of 10-18 carbon atoms (e.g. lauryl, octadecyl, decyl or cetyl alcohol) in aqueous acidic solution (e.g. in dilute sulphuric or phosphoric acid, preferably of a concentration of 0.6-3 per cent by weight and advantageously containing 0.1-0.2 per cent by weight of the sulphuric ester). The treatment may be effected by suspending or agitating the carbon in the acidic solution or by passing the solution through a bed of the carbon.  Specification 619,566, [Group IV (b)], is referred to.ALSO:In the concentration and recovery of streptomycin by adsorption on and elution from activated carbon, the adsorption and elution efficiencies of the carbon are improved by treating it with the acid sulphuric ester of a saturated aliphatic alcohol of 10-18 carbon atoms in aqueous acidic solution (e.g. in dilute sulphuric or phosphoric acid, preferably of a concentration of 0.6-3 per cent by weight and advantageously containing 0.1-0.2 per cent by weight of the sulphuric ester).  The treatment may be effected by suspending or agitating the carbon in the acidic solution or by passing the solution through a bed of the carbon, and may be applied to the regeneration of carbon which has deteriorated through repeated use, or (especially in the case of steam-activated carbons) to the preliminary treatment of the carbon to improve its initial adsorption efficiency. Alternatively, the acidic solution may be used to elute the bed of carbon charged with streptomycin, the first portions of the eluate being found to be substantially free from the sulphuric ester, so that elution may be stopped as soon as it begins to appear in the eluate, by which time most of the streptomycin has been removed. Examples illustrate various methods of carrying out the invention, using monolauryl and mono-octadecyl sulphates.  Other sulphuric esters specified are those of decyl and cetyl alcohols. Specification 619,566 is referred to.

Abstract: 272,288. Maurich, E. March 9, 1926. Enlarging, copying, and reducing.-Printing apparatus for colour kinematography comprises two kinematograph apparatus having bodies exactly alike and adjustable in relative position: a lens system is placed between them so that printing may be effected by projection in either direction. As shown in Fig. 1, each apparatus 1, 2 is adjustable transversely in dovetail guides by screws 4, and the gates 11 are exchangeable, and adjustable vertically and laterally by screws 12. A lens system 7, preferably producing an erect image, shutters 15<a> of known type, film punches 19, connected so that they operate simultaneously, a lamp 10, and a telescope 13 for viewing the projected image, are provided. The mechanisms are synchronously driven by means permitting their relative speeds to be varied, and shutters 20, Fig. 5, may be provided to cover the unwanted negative images when printing all the records of one colour from films in which groups of colour records 15, 16, 17 occupy one normal image area. The positives may be printed on separate films which are cemented together after colouring, the emulsions on the outer films being turned inwards. Alternatively, the images may be succesively printed in superposition on one film which is resensitized on one or both sides between printings. When printing from multicolour records, separate negatives for each colour are first produced by printing through colour screens. A modification is described in which the two apparatus 1, 2 are arranged at an angle to one another and projection is effected with the aid of a, reflecting prism.
