Title: Improvements in weighing scales
IPC: G01G5/04
Filed: 1947-01-25
Abstract: 635,702. Weighing-apparatus. AVERY, Ltd., W. & T. Jan. 25, 1947 No. 2370. Convention date, July 26, 1943. [Class 143] A hydraulic force-transmitting capsule for use with a weighing scale has a pressure plate adapted to act upon hydraulic fluid contained within a base member and is characterized in that the diaphragm connecting these members comprises a plurality of closely spaced inverted U - shaped lengths of readily bendable, non-stretchable material, the spaces there between being sealed with a universally flexible material. The platform 2, Fig. 1, is supported through swing links 5 on four hydraulic capsules 15 which are mechanically coupled by stabilizing frame 13, and hydraulically connected, through pipes 16, to individual, receiving elements 17 which, through struts 19, a gathering lever 21 and a rod 27 transmit mechanical force to a weighbeam 29. The capsules, which may be square, rectangular, triangular, octagonal or circular, have fluid containing base portions 32, Figs. III and VI, and pressure plates 31 contained therein and connected thereto by flexible non-stretchable diaphragms 33. The diaphragms used with polygonal capsules consist of a number of strips, each of which extends the full length of one side of the capsule and is bent to an inverted U-shape from flat strips, the straight limbs of which are in contact with members 35 which clamp the diaphragm strips to the base 32 and plate 31. At the junction of each pair of capsule sides the diaphragm strips are mitred and the space therebetween is sealed by rubber sheet. Thus none of the load force on the plate 31 is absorbed by the diaphragm when it is distorted under load. Circular capsules have a diaphragm in the form of a preformed half torus 44, Fig. XI, with radial slots 43 cut therein, said half torus being lined with rubber sheet 45. In a modification (not shown) the slotted torus is replaced by a series of lengths of wire bent into semi-circles, the part toroidal surface formed thereby being lined with rubber sheet as before. Both the edges of the slotted torus and the ends of the wires are secured to the base portion 32 and plate 31 by clamping rings 35d. Upward movement of the plate 31 is limited in every case by the provision of fixed abutment members 42.

Patent GB-668933-A (GB)
Title: Improvements in x-ray tubes
IPC: H01J35/00
Filed: 1950-02-02
Abstract: 668,933. X-ray tubes. METROPOLITANVICKERS ELECTRICAL CO., Ltd. (Compagnie Generale de Radiologie). Feb. 2, 1950, No. 2777/50. Class 39 (i). Monochromatic X-rays are produced by fluorescent radiation from a secondary target excited by X-ray emission from the anode. The materials are chosen so that the wavelength of the principal characteristic ray of the anode emission is within an absorption band of the secondary target surface; in this way almost all the X-radiation falling on the secondary target is absorbed or converted into monochromatic radiation. Fig. 1a illustrates the principle as exemplified by a rhodium anode and a molybdenum secondary target; the principal ray in the rhodium emission spectrum, Kα, is seen to be within the absorption band of the molybdenum secondary target, shown in dotted lines, and just below the absorption discontinuity. Fig. 2 shows a specific construction, in which 1 is a rhodiumplated copper anode having a water jacket 2. In operation, electrons from the open spiral cathode 7 strike the anode, the resulting X- radiation in turn exciting fluorescent radiation from the secondary electrode 8. Because of its conical shape, the monochromatic beam leaves the tube through the hole 5, which is covered by a beryllium bead 6. A thin zirconium cylinder 13 acts as a filter for unwanted radiation and also prevents cathode deposition on the secondary electrode. Fig. 3a is another embodiment with two filaments 16, and a semi-cylindrical trough anode 3<SP>1</SP>, the secondary target being the face of a projection 17. Instead of a rhodium anode, palladium or silver may also be used with a molybdenum secondary target. With a copper secondary target, germanium or gallium anodes may be used, and other anode/secondary-target combinations include zinc/nickel, copper/cobalt, nickel/iron, cobalt/manganese, iron/chromium, and antimony/silver. The secondary target may be on the cathode itself, if formed of material suitable for both electron emission and fluorescent radiation. In this case a molybdenum cathode may be used with a rhodium-plated copper anode, whilst tantalum, rhenium or osmium cathodes may be used with germanium, arsenic or selenium anodes. Figs. 4 and 5 (not shown) are examples of this two-electrode type. The tubes may be made in demountable form.

Abstract: 5 9 4, 2 3 4. Mixing fluids in flow. RITTER CO., Inc. Feb. 6, 1945, No. 3022. Convention date, Feb. 18, 1944. [Class 86] A device for mixing a liquid under pressure with a further liquid comprises a container having a piston movable therein so as to divide the container into two separate compartments each variable in capacity in mutually opposite sense, a first valve means for connecting the first compartment alternatively to a supply of the pressure liquid or to waste, a second valve means for alternatively closing or opening a connection between the second compartment and a supply of the further liquid and a mixing chamber connected directly with the source of pressure liquid and by way of a non-return valve with the second compartment. The two valve means are interconnected for operation by a common handle whereby in one operative position the first compartment is connected to waste and the second compartment is connected with the further liquid supply and filled therewith, and in another operative position the second compartment is cut off from the further liquid supply and the first compartment is connected with the pressure liquid supply to cause the further liquid to be expelled from the second compartment through the non-return valve to the mixing chamber. A cylindrical chamber 10 is divided into two compartments 29, 51 by a piston 18 slidable on a rod 16. A valve 60 connects the compartment 51, either through a port 61 and a tube 53 with a supply of water under pressure for raising the piston 18, or to waste through a further valve port and a discharge pipe 59. A second valve 73 is adapted either to connect the compartment 29 with an air vent 72 and a spout 70 supplied with antiseptic solution, or to close these connections. The valves 60. 73 are coupled by a shaft 66 for operation by a common handle 82, in one position of which the compartment 51 is connected to waste and the compartment 29 is filled with antiseptic solution. In a second operative position of the handle 82, the valve 73 is closed and the compartment 51 is connected through the valve 60 to the water supply whereby the piston 18 is raised. Antiseptic solution is then expelled from the compartment 29 through a non-return ball valve contained in a housing 31 and an adjustable valve 34 into a tubular chamber 26 where it is mixed with water supplied through an inlet 23 from the same pressure source as that of the water operating the piston 18. The antiseptic solution passes through a tube 49 of smaller diameter than that of the chamber 26 so that it is induced by the flow of water through the inlet 23. The mixture passes from the passage 26 to an outlet nozzle and its proportions may be varied by a screw adjustment of the valve 34 by rotation of a control lever 45.
