Title: Improvements in or relating to electric discharge lamps comprising luminescent materials
IPC: C09K11/68
Filed: 1936-04-27
Abstract: 472,769. Electric discharge lamps associated with luminescent materials. GENERAL ELECTRIC CO., Ltd., McKEAG, A. H., and RANDALL, J. T. April 27, 1936, No. 11918. [Class 39 (i)] [Also in Group XX] A lamp filled with a gas or vapour (e.g. neon or argon-mercury vapour) and excited by a lowenergy agency is associated with lead-activated calcium tungstate as luminescent material, the lead serving greatly to increase the fluorescence of the tungstate. The material may be applied to the inner surface of the lamp envelope, or outside the quartz envelope of a mercury vapour discharge lamp, e.g. on an outer jacket; it gives pink light with a neon discharge, and blue light with an argon-mercury-vapour discharge ; and it may be prepared from equimolecular. quantities of calcium carbonate purified to render it spectroscopically free from lead, and tungstic acid purified by a recrystallization-precipitation process involving the cycle tungstic acid, ammonium tungstate, tungstic acid, &c., with addition of about 0À1 per cent of lead in the form of nitrate. It is stated that calcium tungstate prepared from pure tungstic oxide and calcium carbonate of analytical purity often contains enough lead to increase the luminescence. Reference is made to luminescent screens, for use with X-ray and cathode-ray tubes, comprising calcium tungstate activated with lead; and to Specifications 369,882 and 457,486. Reference has been directed by the Comptroller to Specifications 369,882 and 457,486.

Title: Improvements in or relating to packing apparatus
IPC: B31B105/00
Filed: 1958-04-16
Abstract: 886,531. Packaging; making cartons. OTT, K., [trading as HABRA-WERK W. F. OTT]. April 16, 1958 [April 24, 1957 ; June 14, 1957 ; June 22, 1957 ; Dec. 13, 1957; Jan. 18, 1958], No. 12057/58. Classes 18 and 94(1). Packages are formed by cutting the side edges of a web to form a series of joined blanks, pressing the blanks into matrices on a movable conveyer by a reciprocating former to produce joined tray-like cartons, filling the cartons, and closing them by application of a further web which is sealed to outwardly turned margins of the carton walls. A tear string may be incorporated beneath the covering web. The apparatus is intended for packaging substances which are poured into the cartons in a molten state and subsequently set. A web 1a is fed past cutters 4 to overlie plates 6 on a conveyer beneath a vertically reciprocatable former 9. The former, which may have a spring-loaded forward section for engaging the leading part of the unfolded web before the main portion to draw sufficient material forward, Fig. 7 (not shown), presses the web between bars 7, 8 on each plate 6 to turn up front and rear walls. Pivoted flaps 14, 14a mounted on the plate 6 (shown on one only) then turn up the side walls 17 and form margins 18 by bending the margins against a projecting rim on the ram, Figs. 7, 8 (not shown), the corner sections forming gussets 16. Means (not shown) may be provided to heat seal the folded gusset portions together. At the next station a second former 9b engages the previously formed carton to assist it in retaining its shape. The conveyer carries the joined cartons to a support 42 above which is filling apparatus (not shown). The margins may be kept free from contamination by the contents by a continuous belt engaging the carton rims and apertured to permit entry of the contents, the belt passing through washing and drying apparatus on its return run, Figs. 12, 13 (not shown). The filled cartons, after having passed beneath a contents levelling plunger, Fig. 7 (not shown), are fed to a further conveyer 45 above which passes the closure web 22. Members 47a, 48, 49 engage beneath the margins and a plunger 24 presses above them to heat seal the seams. The closed cartons then pass to a support 31 where co-operating elements 52, 53 separate them from the web, fold in the gussets 16, Fig. 3, and fold down the marginal seams to produce the package shown in Fig. 5. A tear thread 60, Fig. 14, may be fed between the cover and carton prior to sealing by an oscillating arm Fig. 16 (not shown). The cartons may be of rectangular configuration. Another form of carton has side and end margins which, in the blank form extend, along adjacent sides of the corner gussets and in the erected carton produce a continuous flange, Figs. 17-22 (not shown).

Abstract: 306,759. Blakeborough, R. A., and Brotherton, C. April 25, 1928. Actuating-mechanism.-A non-return valve of the type comprising a single hinged valve member normally held in its open position by a release catch mechanism, has the catch mechanism connected to the valve spindle through a ratchet device, to permit the catch to be reset and allow the valve to open automatically when pressure is restored or to be opened by manual operation. In the form shown in the Figure a ratchet member m slidably mounted on the valve spindle is pressed by a spring k<1> into engagement with a corresponding member i' on an arm loosely mounted on the valve spindle and held at its free end by a pivoted catch g<1>. A counterbalanced catch lever e which normally engages the toe f<1> of a tumbler weight f is coupled by a Bowden wire to a governor or tachometer associated with the pump inducing the flow, so that when the speed of the pump falls the tumbler drops and operates the release catch g' against the action of a spring n. A lever p and ratchet p<1> normally held out of engagement is fitted to the valve spindle for hand actuation. The catch mechanism may be mounted on a separate framework and connected to the valve by means of quadrants and a flexible connection, a toothed pinion engaging the upper quadrant for hand actuation.

[Class 87 (ii)] [Also in Group XXII] The tamping hammer is raised by cams, and a toggle link system is provided by means of which the hammer can be raised and held in an inoperative system out of the orbit of the cams. Fig. 2 shows a brick-tamping machine in its normal running position. The hammer 12 is carried by a ram 11 secured to a yoke 15 and is raised by a pair of cams 19 which act on rollers 17 on the yoke. The cams are secured on a driven shaft 20 and have two portions 19A, 19B which raise the hammer and allow it to drop twice for each revolution of the cam-shaft. In order that the machine may operate, the handle 27 must be held in the " in " position shown in Fig. 2. When the tamping has been completed, the handle 27 is released, whereupon a spring 29 acting through an arm 28 rocks a toggle 30, 31 about a fulcrum 26 to position the end of the toggle link 31 beneath the yoke 15 as shown in Fig. 4.
