Abstract: 1284684 Treating wool CIBA-GEIGY AG 9 Nov 1970 [10 Nov 1969] 53235/70 Heading D1P Prior to its being rendered non-felting by the exhaustion process using synthetic resins, wool is treated with an aqueous preparation which contains 0.1-2%, by weight of dichloroisocyanuric acid or an alkali metal salt thereof, relative to the weight of the wool treated. Suitable synthetic resins are (a) reaction products of basic polyamides with epoxides, alkyl ethers of aminoplast precondensates, polyfunctional compounds or epoxide-aminoplast-alkyl ether reaction products, (b) reaction products of epoxide-amine reaction products with epoxides, and (c) epoxide-polycarboxylic acid reaction products with amines or amine-epoxide reaction products. The wool may be dyed before or after the dichloroisocyanuric treatment, but before synthetic resin treatment.

Title: Scintillation camera with resolution
IPC: G01T1/164
Filed: 1972-11-21
Abstract: 1410216 Scintillation camera G D SEARLE & CO 21 Nov 1972 [22 Nov 1971] 53831/72 Heading H4F In the scintillation camera described in Specification 1,339,330, the use of the second filter for scanning the documentation means stops the majority of the display on the C.R.T. from remaking the documentation means. It is therefore proposed to retain the scanning radiation filter having an array of radiation passageways but to funnel or gether together all the co-ordinate defining signals from the detector head arising from the scanning by any particular radiation passageway so that the corresponding displays on the documentation means are all positioned corresponding to the central axis of said radiation passageway. Such funnelling may be electronic or optical. In an electronic embodiment, Figs. 1, 1B, 4, 8, the radiation filter 20, Fig. 4, is incrementally raster scanned so the axis of a radiation passageway, e.g. 211, successively occupies the coordinates X0Y0, X1Y0' X2Y0, ... X0Y7, Fig. 8, such that all of the incident radiation passes through the radiation filter during the scan. The filter scanning is controlled by X and Y scalers, the digital outputs of which are also converted to analogue form for subtractive combination in A to D converters 60, 70 with the X and Y scintillation co-ordinates from the detector. This causes the grouping of the detector output signals into "channels" corresponding to the radiation passageways. The grouped output signals are then reconverted to analogue form in converters 80 and simultaneously repositioned to the axes of the passageways by the addition of the outputs of the scalers. The resulting X, Y deflection signals are applied to the CRT display 100. An analogue, continuous scan version is described, Fig. 1A (not shown). In an optical embodiment, Figs. 3, 6, 7, the radiation filter 20 is still used, but the funnelling is done by an array of conical light guides 300 gathering the display on the face of the CRT 90 into the required axial areas, the light guides being scanned across the face and documentation means in synchronism with the scanning of the radiation filter.

When a key 22 is depressed against a spring 20, the magnets 14, 16 move down away from the ferrite core 12, permitting it to desaturate, the core being used as a transformer or a variable inductor to give a coded or non-coded electric output when a plurality of such switches are used in a keyboard, by appropriate threading of windings through one or more cores each. In the keyboard, the switch housings are located in respective holes in a support plate, the latter being gripped between ledges 10a and (not shown) resilient ears protruding at an angle from the housings. The recesses 10e of the switches lying in a row of the keyboard are aligned. Each switch may have a further recess in the central portion extending upwards from recess 10e, windings (if any) not threading the respective core being trapped in this further recess by the core.

Abstract: 1453969 Continuous casting CONCAST AG 4 Dec 1973 [5 Dec 1972] 56214/73 Heading B3F [Also in Division G3] A steel casting 3, withdrawn (e.g. at more than 1 m./min.) from a cooled mould 1 along a guideway 4, is subjected, in a zone 6 extending along at least a part of the guideway, to a gaseous medium at a pressure corresponding substantially to the ferrostatic pressure of the casting core until the casting has fully solidified, the medium being principally steam generated by spraying the surface of the casting 3 with water, any deviations in the steam pressure from that required being compensated for and whenever the pressure falls below requirements it is restored by admitting compressed air to the zone. When the steam pressure is excessive, the level of unevaporated water collected in compartments 24-27 of a pressure chamber 20 (e.g. constructed as in Specification 1,398,891) is lowered. The apparatus described is similar to that of Specification 1,453,841, but the relative pressures in the compartments 24-27 are not determined by valves interconnecting adjacent compartments but by a pressure gauge 62 at each compartment which generates a signal at three pressure levels; i.e. to open a motorized valve 33 when maximum permissible pressure is attained; to open an electromagnetic valve 60 for the introduction of compressed air from a reservoir 52 charged by a compressor 50 when a maximum pressure obtains; and to close both valves 33 and 60 when an average pressure is signalled. The motorized valve 33 is also operated by a gauge sensing the level in a compartment of the pressure chamber to release excess water and scale and is overridden by the pressure gauge 62, if maximum pressure obtains, even with no water present. The gas pressure arrangement may extend up as far as the mould 1. Specifications 1,354,758 and 1,112,017 are referred to.
