Title: Monochromatic x-ray source
IPC: G21G4/04
Filed: 1965-12-02
Abstract: 1,108,399. Monochromatic X-ray source. PANAMETRICS Inc. 2 Dec., 1965 [7 Dec., 1964], No. 51142/65. Heading H5R. Monochromatic X-ray beam source comprises an α-particle emitter mounted on a base member and arranged so that the α-particles are incident on a target element and result in the emission of characteristic X-rays which then pass through a selective filter element and so that the α-particles themselves are not incident upon the filter. The target element may be thick enough to prevent the passage of α- particles therethrough. The target can be a single element or a homogeneous mixture of materials that emit X-rays at separated energy levels. As shown in Fig. 1, the base member may be a hollow cylinder 10 with an annular ledge 11 at one end, the α-particle emitter 12 in the form of a ring being mounted on this ledge. The disc-shaped target 20 is mounted across the end of the cylinder and is spaced apart from the emitter by liner 14 which does not emit radiation in the region of the characteristic X-rays of the target and any such radiation is therefore stopped by filter 13. The target element (28) may be interposed between the emitter (22) and filter (30), see Fig. 2 (not shown). A plurality of monochromatic X-ray beams may be obtained using a single source, see Figs. 4 and 5 (not shown), by using as the target a plurality of sectors (34) formed of different elements and having a means, e.g. wheel (32), to move any one of these sectors to a position between the α-particle emitter (38) and the filter (36). Specified sources are Po-209, Po-210, Pu-239, Pa-227, Bi-197 and At-217. These sources may be sealed within a layer of Au, Be, C or Mo and mounted on a base of similar material. Specified targets are Al, Ni and Cu. The filter may be an element of atomic number 1 or 2 less than that of the target element. Specified liners are of Be and Au.

Abstract: 1,127,162. Treating hides, skins, leather &c. with liquids; tanning. MOSKOVSKY INSTITUT KHIMICHESKOGO MASHINOSTROENIYA. Dec.2, 1965, No.51164/65 Heading C6C. In soaking, tanning and washing material having a complex capillary-porous structure, such as hides and skins, to produce leather, or in soaking and washing leather itself, the material or leather is submerged in the treating liquid and subjected to hydro-elastic oscillations, which are imparted to the liquid and are generated by electrical pulse discharges, so that their frequencies extend over a wide band or spectrum. The discharges may be generated in succession, with a pulse repetition frequency of 50 to 100 pulses per second. The electrical pulses may have voltages of 30 to 50 kV., each electrical pulse may have a pulse length of 1 micro-second and the width of the frequency spectrum may be 1 megacycle. The material 1 may be supported, by movable holders 5, vertically as shown in Fig. 2 or horizontally Fig.3 (not shown), in a liquid of low electrical conductivity, which is contained in an electrically earthed container 2 provided, on top and/or bottom, with electrodes 3 connected to a high-voltage, electrical pulse oscillator 4, to which alternating electric current is supplied. If the material is to be treated in a liquid of high electrical conductivity, in the container 2, the electrical discharges are generated in an auxiliary container 6, Fig. 4, filled with another suitable liquid, such as water, and the resulting hydro-elastic oscillations are transmitted through the bottom 7 of container 2, which bottom functions as a diaphragm imparting additional oscillations to the treating liquid, thus widening the frequency spectrum.

Abstract: 1528815 Laminates TEXSA SA 15 Dec 1975 51317/75 Heading B5N Multi layer waterproof strips having at least two continuous flexible plastics layers and therebetween, as adhesive medium, an evenly distributed layer of asphalt mixture, are produced by moving the plastics material layers 1A and 1B along respective paths to an asphalt mixture application point, applying between the plastics layers 1A and 1B at the application point a layer of asphalt mixtures 6, comprising 65-70% by weight asphalt, 25-30% by weight slate shale and 5-10% by weight latex or other elastomeric material in a suitable state at a temperature of 170 to 190 C., bonding the plastics material and asphalt layers together under pressure with the asphalt layer between the plastics material layers, and simultaneously cooling the plastics layers with a water film applied to the surfaces of the plastics layers opposite to the surfaces of the layers which contact the asphalt mixture, the water film being applied to each plastics layer at a distance of 20-40 cm before the application point, thereby avoiding damage to the plastics material of the layers due to the heat given off by the hot molten asphalt. Plastics layers 1A and 1B may partially wrap rollers 3A and 3B rotating in opposite directions thereby forming an adjustable nip into which the fluid asphalt mixture fed from source 7 is poured from box 5. Two or more pairs of rollers may act downstream to add further plastics web layers and asphalt mixture layers to the initial three layer strip 8. Rollers 3A and 3B operate partially submerged in water 9 to create around their periphery water films for cooling the plastics layers. The rollers may also be cooled by internal circulation of water introduced through tubular shafts 4A and 4B. The plastics layer which may be of high-pressure, low-density polyethylene may have a thickness of 0À01- 0À10 mm and the asphalt mixture layer may have a thickness of 1-4 mm. In an alternative arrangement the rollers may be replaced by endless belts.
Patent GB-513760-A (GB)
Abstract: 513,760. Melamine. BLOXHAM, A. G. June 7, 1938, No. 16879. Convention date, June 5, 1937. Addition to 466,957. [Class 2 (iii)] In the conversion of dicyandiamide or cyanamide into melamine in a closed reaction vessel by a process of the parent Specification, the reaction vessel is initially packed with the starting material or materials with a degree of filling of at least 30 per cent. By degree of filling is meant the percentage of the total capacity of the vessel occupied by the starting materials when in the air-free state, e.g. when molten in the case of solid materials. With a commercial dicyandiamide, the minimum degree of filling is realized by charging the vessel to the top. The process may be carried out in a pressed vessel sealed hydraulically, or by continuously forcing the reaction mass through a tube fitted with a pressure-loaded valve. In the case of powdered reaction masses, the material itself forms a plug before becoming molten. According to the examples melamine is obtained in high yield when (1) dicyandiamide is pressed into a tin vessel in the form of a plate provided with a' cover until completely filled and the vessel heated in a press ; when the reaction is over the press is opened and the cake of reaction product removed from the vessel; the dicyandiamide may be mixed with an equal part of iron powder or of a liquid heat buffer, such as paraffin oil or anthracene oil; (2) a mixture of dicyandiamide and paraffin oil is charged into a closed tube, and after heating in an oil bath, the product freed from oil by means of petroleum ether ; the reaction mixture may also be forced continuously through a heated valved reaction tube; (3) dicyandiamide and liquid ammonia are heated in a closed reaction tube ; (4) a closed reaction tube is charged with dicyandiamide or filled with molten cyanamide and heated in an oil bath.

Title: Improvements in or relating to load lifting apparatus
IPC: B66F9/08
Filed: 1968-11-01
Abstract: 1,200,148. Masted lift trucks. TOYODA AUTOMATIC LOOM WORKS Ltd. 1 Nov., 1968 [7 Nov.. 1967; 14 Dec., 1967], No. 51848/68. Heading B8H. In a masted lift truck, the lifting carriage and movable mast section are each provided with pairs of upper, middle and lower guide rollers mounted for rotation about parallel areas and arranged to resist lateral thrust caused by eccentric loading. As shown, the lifting carriage 15, 17 is provided with guide rollers 21, 22, 23 engaging the movable mast uprights 7, and the channel of each upright 7 is formed by forward and rear flanges 7a, 7b, extending from a web. A curved rolling surface 7c is formed at the inside corner between the rearward flange 7b and the web and has the same radius of curvature as the periphery of the rollers. A supporting surface 7d is formed on the web in continuation of the surface 7c. The upper rollers are prevented from contacting the surfaces 7d by retaining rings 25, but the lower rollers 23 are adjusted laterally by shims 26 so that they contact the surfaces 7c. The middle rollers 22 are of smaller diameter than the upper rollers 21 so that they do not contact the forward flanges 7a until the upper rollers 21 are raised above the uprights 7. The surfaces 7c, 7d extend downwardly from a point a predetermined distance from the upper end of the uprights. Second curved surfaces and supporting surfaces 7d<SP>1</SP> are provided in the other upright inside corner and extend upwardly from the above point. In operation, when the lifting carriage is raised from its lowered position, the upper rollers 21 engage the forward flange 7a and the lower rollers 23 engage the rearward flange 7b, the curved surface 7c and the supporting surface 7d. The middle roller 22 on the side on which an eccentric load is supported, engages the surface 7d and rotates in the same direction as the lower rollers, and the other middle roller does not engage the adjacent upright. As the lifting carriage approaches its uppermost position, the middle roller passes from the surface 7d to the surface 7d<SP>1</SP> adjacent the forward flange and its direction of rotation is reversed. When the upper rollers 21 project above the uprights 7, the middle rollers 22 engage the forward flange 7a and adjacent curved surface. The fixed uprights are shaped similarly to the uprights 7 and are engaged by upper, middle and lower rollers mounted on the uprights 7, Figs. 12-14 (not shown).

Title: Drive apparatus and xerographic copying machine employing the drive apparatus
IPC: G03B27/50
Filed: 1969-11-11
Abstract: 1,249,045. Electro-photographic copying apparatus. INTERNATIONAL BUSINESS MACHINE CORP. Nov. 11, 1969 [Nov.25, 1968], No. 55070/ 69. Heading G2H. In electro-photographic apparatus, a mechanism reciprocates an original supporting carriage, or a lens and/or light source carriage for line-by-line copying. As shown, an original carriage 13 is reciprocated by cables 56 through a sheave 62. Image-receiving drum 10 is rotated by a motor 42, and, during scanning, sheave 62 is rotated by drum shaft 52 through clutch 64. A spring 66 is tensioned during scanning and on disengagement of clutch 64 rotates sheave 62 in the reverse direction to return carriage 13. A copying cycle starts with spring 66 tensioned. Sheave 62 is accelerated thereby and by means of a drive pin 110 Fig.3 drives a gear 80 which meshes with a gear 108 on a shaft 104 bearing capstans 134, 136 connected by a cable 138 to a cam-groove brake-capstan 128. When sheave 62 reaches a predetermined velocity an over-riding clutch 140 Fig. 4 (not shown) locks capstan 128 on to a shaft 130 driven by motor 42. Carriage 13 is thus returned at a constant velocity, until the configuration of capstan 128 begins to slow pulley 62. A cam 102 on shaft 104 then engages a follower 114 on sheave 62 to bring it to a halt. Near the end of this motion, an arm 118 moves a wedge 116 allowing drive pin 110 to move within slot 112 striking a latch 98 which allows pawls 82, 92 to engage a disc 72 fixed to drum shaft 52. Gear 80 is now rotated in the opposite direction by shaft 52 and drives gear 108. Cam 102 thus starts to accelerate sheave 62 through follower 114, so that by the time gear 80 and drive pin 110 re-engage sheave 62 has reached the velocity of gear 80. Carriage 13 is thus moved in the scanning direction at a constant velocity until a pin 90 disengages the pawls 82, 92 from disc 72. Sheave 62 is then brought to a halt by the increasing tension of spring 66. A brake spring 146 on shaft 104 will prevent the start of another cycle until released by a solenoid operated sleeve 154. Drum 10 contains a reel of photo-conductive tape 18 Fig. 1 (not shown) which is advanced after a predetermined number of copies have been made. Copy paper (24) is severed at (26), contacted with drum 10 and separated therefrom by an air nozzle (30). Drum 10 is cleaned by a corona unit (32), a brush (34) and a vacuum source leading to a disposable bag (36). (For Figures see next page)
