Filed: 1927-10-04
Abstract: 303,461. Avery, Ltd., W. & T., Sykes, C. M., and Binns, A. Oct. 4, 1927. Platform machines; locking-mechanism.-In a platform weighing machine of the portable type the weighing mechanism is locked automatically if the machine is moved bodily when in the weighing position, and means are provided for effecting the unlocking of the mechanism as required. A disc 12 is secured to the axle 6 of the ground wheels 5, and in the unlocked position of the mechanism a forked pawl 13 bears vertically upon the disc. The pawl is carried by a lever 14 connected by a rod 16 to one corner of a triangular plate 17 secured at another corner to the pivot 18 of a handle 19. The remaining corner of the plate is connected by a link 20 to a bell-crank lever 21 carrying a locking roller 23. If the machine be moved bodily the wheel 12 rotates and the pawl 13 is displaced, thus allowing the lever 14 to descend under the influence of a spring 26 and, acting through the link 16, plate 17 and link 20, to raise the locking roller 23 against the scale beam 8 and clamp it against a stop 24 thereby locking the mechanism. When the machine is to be used again, the handle 19 is rotated to withdraw the locking roller 23 from the beam and also to raise the lever 14 and permit the pawl 13 to reassume the position shown under the influence of a spring 27. A spring 25 assists the unlocking movement of the handle 19.

Title: Area sources of radioactivity and a method of making them
IPC: G21G4/06
Filed: 1965-06-22
Abstract: A radio-active source for a self-luminous structure comprises a malleable and ductile metal plate having pressed into the surface thereof discrete spheroidal elements, each consisting of a hard spheroidal core carrying radio-active material and coated with a layer of metal.  A layer of phosphor such as zinc sulphide, preferably in a plastics binder, is coated on the plate.  The spheroidal elements have a size range of 5 to 250 microns.  The metal coating is between 0.2 and 5 microns thick.  The activity of the surface of the plate is at least one microcurie per sq. inch. In an example, glass spheroids are formed, leached with acid, impregnated by ion exchange with radioactive promethium-147, heated to 1000 DEG C., washed, spheres of 40-50 micron size separated, plated with nickel (see Divisions C4-C7), sprinkled on an aluminium plate coated with an adhesive, pressed at 350 DEG  C., and washed.  A sulphonated polystyrene-divinyl benzene may be used instead of glass for the speroid cores.  Other suitable metals for the plate are Cd, Au, Ag, Zn and Pb; the spheroids may be plated with Co instead of Ni. Other radio-isotopes are beta emitters Sr-90 and Y-90, alpha emitter Am-241, and gamma emitter Cs-137 which forms Ba-137M.ALSO:source (see Division G6), hard spheroidal cores carrying radioactive material are coated with a layer of metal.  Glass spheroids are leached with acid, impregnated with radioactive material, and a 40-50 micron size range separated; the spheroids are placed in a stannous chloride solution to form a thin layer of tin and then in silver nitrate solution to form a second thin layer of silver, which is replaced by palladium using a palladium chloride solution; finally nickel is applied using a plating solution containing nickel chloride, sodium hydroxy-acetate, and sodium hypophosphite.  To form the radioactive source, the coated spheroids are applied as a monolayer to an aluminium sheet coated with an adhesive and subjected to pressure at elevated temperature.

Abstract: 1,144,089. Extrusion adapters; extruding multilayer sheets. DOW CHEMICAL CO. 9 June, 1967, No. 26787/67. Headings B5A and B5B. In an extrusion adapter 10, used in the production of multi-layer films or sheets, a housing 11 defines a central passageway 13 having an inlet end 15 communicating with a polymer source, and an outlet 14 connected to a sheeting die (not shown). The housing also defines at least one annular plenum 57, the plenum being supplied with a second polymer through passageway 59, and being connected to the central passage by annular passageway 58; at least one bushing 61 disposed within the central passageway and having an orifice 66 of elongate cross-sectional configuration in a plane normal to the axis of the central passage, the elongate end being disposed between the annular passageway and the discharge end of the central passage and the bushing defining a bushing passageway through the said central passage; a restriction means, which may comprise a sleeve 33 of cylindrical configuration adjustably mounted adjacent to the elongate orifice of the bushing, and an adjustment means, which may comprise an annular collar 35 having camming surfaces 36 and 37 which co-operate with screws 22 and 23, to selectively restrict a space 44 between the bushing and the inner wall of the central passage. In operation a polymer is introduced into the central passage and attains an elongate configuration at the orifice 66 of bushing 61, where it is encapsulated by a second polymer introduced from plenum 57 through annular passageway 58, the restricting means selectively restricting the flow of the material forming the outer layer at the location where the two layers are combined and so varying the thickness of the said outer layer, the composite stream then being extruded from the sheeting die. Other restricting and adjusting means mentioned include adjustable pins movably positioned adjacent to the discharge end of the bushing, or the position of the bushing may be altered relative to a conical wall of the central passage. The number of layers in the resultant composite film may be increased by using more than one annular plenum, each plenum being connected to a different polymer source. The housing may comprise a plurality of portions held together in sealing relationship, the annular plenums being defined by means of adjacent body portions.

Abstract: 644,139. Skips. INTERNATIONAL COMBUSTION (HOLDINGS), Ltd. Oct. 8, 1947, No. 26981. [Class 78 (iii)] In a skip of the kind in which material is automatically discharged at the pit head through a door in the bottom of the skip, the device for locking the door comprises two opposed sliding bolts which are counterweighted or spring-loaded in the locked position and are operated through a shaft which is under the body of the skip and rotated by a roller secured thereto which projects beyond the back of the skip and when the skip approaches the surface, engages a ramp secured in the shaft so as to cause the bolts to be withdrawn and release the door. As shown, the door h of a skip d is locked by bolts a connected to an arm e carried on one end of a shaft c. When the skip approaches the surface, a roller g on the other end of the shaft contacts a ramp j, whereby the shaft is turned so as to withdraw the bolts a from engagement with the side walls h<1> of the door. Before the skip reaches door-unlocking position, rollers k on the door engage ramps l in the shaft, whereby the load is taken off the bolts so as to allow them to be withdrawn. In a modification the bolts are operated by separate shafts; each having a roller engaging a separate ramp in the shaft.
