Title: Improvements relating to phosphors
IPC: C09K11/74
Filed: 1954-06-10
Abstract: 754,779. Luminescent materials. GENERAL ELECTRIC CO. June 10, 1954 [June 30, 1953], No. 17119/54. Class 39 (1). A phosphor comprises a complex phosphate of calcium, sodium and a metal M with manganese and antimony as activators where M is a metal of the second group with an atomic weight less than 200, other than beryllium. The atomic ratio of M to Ca is 0-1.5 and Na to Ca+M is 0.001-0.50; Mn to Ca+M+Na is 0-0.42 and Sb to Ca+M+Na+Mn is 0.2-9. The ratio of base to acid in the complex is from 1.6 to 2.1. The addition of sodium to the calcium pyrophosphate increases the U.V. absorption and raises the luminous or quantum efficiency. Further matrix modification by the incorporation of cadmium, zinc, magnesium, barium and strontium gives improved fluorescence and stability particularly to cathode rays in some cases. Cadmium is effective when both activators Sb and Mn are present, and all the above-mentioned elements affect the Sb activated compound favourably. The emissions and efficiencies are discussed in the Specification. The phosphors are produced in two ways. The first is a dry method in which a mixture of calcium phosphate, diammonium hydrogen phosphate, sodium carbonate, antimony trioxide and other desired compounds are ball-milled in dry condition, screened and fired at 825‹ C. In the second, a wet method, orthophosphoric acid is added to a thin suspension of the other carbonate or oxide materials in demineralized water, the mass being dried and fired. The compound is stated to show fluorescence before firing. The sodium may be added as carbonate, bicarbonate or halide.

Title: Container inspection apparatus and method of inspection
IPC: B07C5/12
Filed: 1975-04-25
Abstract: 1493537 Inspecting transparent containers BARRY-WEHMILLER CO 25 April 1975 [20 May 1974] 17306/75 Heading G1A Apparatus for this comprises sources 16, 17 directing light in different paths across a conveyer 10, each crossing defining an inspection station, means responsive to the movement of each container C 1 , C 2 ,C 3 ,C 4  through said stations to energize the sources in sequence producing an image of each container from different angles, means directing the light to means 29, on the other side of conveyer 10 to the sources, scanning the images. Devices 11 and 12 direct beams 50a and 50c to photo-cells 11A, 12A. Light box 13 is divided by wall W and has in each compartment linear flash tubes, 16, 17 with axes of elongation parallel to the container axes activated by a container interrupting beams 50a and 50c respectively to give a pulse of the order of 0À5ms or less producing in conjunction with cylindrical parabolic reflectors 18, 20, beams 16A, 18A. Glass or plastics diffuser plates 19, 21 are at an angle D of 40 to 50 degrees. Housing 14 contains front surfaced mirrors 22, 31 perpendicular to the conveyer and hence at 45 degrees to the beams 16A, 18A. The principal foci of lenses 23 and 32 are at the bottle axes at the inspection stations. After the beam splitting prism 24 with equal transmittance and reflectance, beams 16E and 18E are converged by lens 25 to form container images at its focal plane. These are projected via filter 30 on to TV camera 29. For beam splitting a mirror may be used instead. A.C. comparator networks 36, 37 detect the light-to-dark and dark-to-light image area changes respectively. Comparator 40 compares the gross change in illumination level with a reference adjustable by control 42. Window memory network 43 produces an electronic window excluding the fringe portion of the container image. Interface circuit 46 alternatively responsive to photo-cells 11A and 12A sends timing pulses to processing network 45 and if there is a foreign object within the electronic window a pulse is fed to reject delay network 49.

Title: Improvements in or connected with helical extrusion apparatus
IPC: B65B1/12
Filed: 1923-07-04
Abstract: 221,600. Jackson, Ltd., J. G., and Jackson, J. G. July 4, 1923. Explosives, apparatus for treating.-Apparatus for filling granular, plastic or pulverulent mate. rials into tins, projectiles, etc. by means of rotatable helical extruders capable of endwise movement relative to the delivery orifice, comprises a hopper A formed with a delivery orifice B and a tubular extension 2 through which extends the helical extruder H. A receptacle C is held against a resilient facing 3 of the orifice by a horizontally sliding head E adapted to be pressed by a cam F which is operated, through wires, by a treadle G. The helical extruder is connected to a shaft 9 of rectangular cross-section and movable endwise through a driving socket J and sleeve 10, all of which are connected to rotate together. A driving clutch 13 is rotated from a pulley K. When the parts are in the position shown in Fig. 1, the helical extruder is moved to the left and into the projectile etc. by depressing a treadle P, which acts through connections 17 - - 19 upon a crosshead N at the end of the shaft 9. When the crosshead reaches its lefthand position it contacts with an abutment 23 on a rod L and causes a clutch 11 on the sleeve 10 to engage the driving clutch 13. The extruder moves back during the filling until the crosshead contacts with an abutment 22 and disconnects the clutches. Adjustable weights. 20 may be provided to reduce the resistance due to friction. A lamp R may be arranged to be extinguished or illuminated when filling is complete, to act as a signal. The extruder may be arranged to rotate while being advanced into the projectile. In a modification, Fig. 7, an extension tube 4 extends into a projectile D so that an unfilled cylindrical recess is left at the open end: Specification 12084/04, [Class 143, Weighing-apparatus &c.], is referred to.

Abstract: 650,308. Bracken-collecting machines. PERBOHNER, S. July 1, 1947, No. 17367. [Class 6(iii)] A bracken - collecting machine comprises a frame 10 mounted on skids 14 and carrying, at its front, pairs of power - driven rollers 31 which grip and uproot the bracken. A motor 15 drives a transverse shaff 23 on which the roller frame 25 is pivoted, and about which it may be adjusted, through a slot 29 and nut 28. The rollers are driven by wormwheels 45 engaging worms 46 on the shaft 23. The worm-wheels 45 are mounted on short shafts 43 coupled to the roller spindles 36 through couplings 37 which permit considerable misalignment between adjacent rollers. The upper bearings for the rollers are arranged to be alternately fixed or laterally movable by means of spring- loaded wedges. The bracken stems are thus gripped between one fixed and one spring-loaded roller. The surface of each roller may be ribbed as at 35 or it may be covered by a strip of canvas loosely wound around the roller. Forwardly-projecting dividers 50 guide the crop towards the rollers.

In example (2), the sodium salt of lauricanilide sulphuric ester is added to the composition of example (1), and used to form a stripping layer. In example (3), the sodium salt of ethylene-bis-(iminodiacetic acid) replaces the sodium hexametaphosphate of example (1).  In example (4), the sodium salt of trimethylaminetricarboxylic acid is used.  In example (7), sodium hexametaphosphate is added to a hydrolysed carageen extract and the solution used to produce a stripping, surface, or antihalation layer.
