Title: Improvements in or relating to a process for preventing the yellowing of photographic images
IPC: G03C1/775
Filed: 1960-06-27
Abstract: 895,960. Photographic diffusion transfer processes. GEVAERT PHOTO-PRODUCTEN N.V. June 27, 1960 [July 1, 1959], No. 22391/60. Class 98(2). A halophosphate or a phosphonyl halide bearing one or more halide atoms directly on the phosphor atom is incorporated in the receiving material, as in the paper support, nuclei layer or barium sulphate layer, used in the silver salt diffusion process to avoid yellowing of the finished images. In Examples (1) dimethyl monochlorophosphate in dioxane is added to a suspension of barium sulphate in aqueous gelatin solution which is applied to a paper support and overcoated with colloidal silver sulphide in gelatin to make receiving material for use in the procedure of Specification 614,155, (2) a composition comprising carboxymethyl cellulose with di-(N- ethylamino)-monochlorophosphate is applied over a hypo-containing nuclei layer and (3) monophenyl dichlorophosphate is used beneath a nuclei layer, also with paper supports, for the transfer. Six further phosphate compounds for the purpose are listed and others are indicated as by structural formula.

Title: Improvements in or relating to single side-band carrier-wave telephony systems
IPC: H04J1/04
Filed: 1951-09-25
Abstract: 697,429. Multiplex systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Sept. 25, 1951 [Sept. 28, 1950], No. 22397/51. Class 40 (iv). In a single-sideband carrier multiplex system, several speech channels are arranged in a basic group, several groups are formed into a basic super-group by means of group carriers, and several super - groups are then shifted in frequency by means of super-group carriers; the lowest frequency ot tne basic group is an integral multiple of half the bandwidth of the basic group, the central frequency of the basic super-group is an integral multiple of half the lowest group carrier frequency, and the frequency spacing between two adjacent super-groups is an integral multiple of half the band-width of a group. As shown, Fig. 1, six speech channels are arranged in a basic group 1 extending from 24 to 72 kc/s, the group bandwidth being 48 kc/s and the channel carrier frequencies being 24, 32, 40 ... 64 kc/s. Five such groups are then formed into a basic supergroup 2 extending from 312 to 552 kc/s with a central frequency of 432 kc/s, the group carrier frequencies being 288, 336 ... 480 kc/s. Supergroup carrier frequencies which are successive integral multiples of 288 kc/s, starting at 1152 kc/s, are used to shift the super-groups so that the spacing between two adjacent super-groups is 48 kc/s. One basic super-group is not displaced in frequency. All the required channel, group and super-group carrier frequencies are obtained from the lowest group carrier frequency 288 kc/s by division and multiplication, Fig. 2.

Title: Improvements in or relating to directional radio antennae
Inventor: BOHM OTTO MORITZ
IPC: H01Q19/20
Filed: 1955-08-04
Abstract: 796,549. Aerials. DECCA RECORD CO., Ltd. Aug. 2, 1956 [Aug. 4, 1955], No. 22517/55. Class 40 (7). A directive aerial arrangement which is sharply directional in one plane and which can be given a required, not so sharp directivity (for example a cosecant pattern) in a plane at right angles thereto comprises reflectors without double curvature thereby easing manufacturing problems. The arrangement consists of a horn primary element facing into a first reflector having at least two differing parabolic reflecting surfaces with common foci in a plane such as to provide the required " not so sharp directivity pattern. This first reflector looks into a second parabolic cylinder reflector which gives the sharply directional pattern. In the embodiment described the two parabolic surfaces of the first reflector join to form a single continuous surface without curvature in the orthogonal direction. One of these surfaces AB (Fig. 2) is part of the parabola ABC with focus at D, whilst the other, BE, is part of the parabola FBE also having a focus at D. The resultant complex surface has the horn primary element 11 at the point D and is the rear face of a reflector 10 (Fig. 1) which is open along the vertical mouth side GH. The reflector 10 looks into the secondary reflector 12 which is parabolic in horizontal section and straight in vertical section. It is pointed out that the vertical pattern of the arrangement is dependent on the dimensioning and positioning, of the parabolic surfaces of the first reflector. The angular inclination of the primary element will determine the proportion of the effective energy being reflected by the surfaces and thus their relative importance in the formation of the resultant complex pattern while lateral shift of the element will alter the relative phasing of the energy travelling via the two surfaces.

Abstract: <PICT:0670751/III/1> Aqueous acetic acids solutions are dehydrated by submitting the solution to extractive distillation using dimethoxytetraethylene glycol as solvent, whereby the water is withdrawn from the still as vapour leaving an anhydrous mixture of acetic acid and the glycol, as residue.  The molecular ratio of glycol to water is preferably within the range of from 1:1 to 5:1. Cellulose spinning bath liquor, containing potassium acetate as well as acetic acid, is evaporated in an evaporator; and the vapours, which contain 10 to 11 per cent of acetic acid, are introduced through pipe 3 into column 1.  Simultaneously, dimethoxytetraethylene glycol is introduced into the column through pipe 4; and the boiler 2 is maintained at about 170 DEG C. Steam comes over from the top of the column; this is condensed, and the water is withdrawn from the system through pipe 7.  A mixture of acetic acid and the glycol collects in boiler 2; and this mixture is passed through pipe 9 to column 10, the boiler 11 of which is maintained at 280 DEG C.  Acetic acid vapours are taken-off from head of column 10, and condensed; and the liquid acid is withdrawn from the system through pipe 14.  The glycol collects in boiler 11, from whence it is fed back to column 1 through pipe 4.  Column 10 may be operated under reduced pressure. Specification 652,844, [Group IV (a)], is referred to.
