Title: Improvements in or relating to collecting mechanism for cigarettes and other rod shaped articles
IPC: A24C5/354
Filed: 1953-10-19
Abstract: 748,794. Step-by-step conveyers. MOLINS, D. W., and MOLINS MACHINE CO., Ltd. Oct. 18, 1954 [Oct. 19, 1953], No. 28850/53. Class 78 (1). Collecting mechanism for cigarettes and other rodshaped articles used, e.g. for collecting cigarettes from a band conveyer 3 and delivering them into a tray 1, comprises a number of narrow grooved bars 5 arranged side-by-side which are so actuated that adjacent bars describe small oscillatory movements 180 degrees out of phase with one another. Alternate bars are mounted on eccentrics 8, 9 mounted on common shafts 10. The space between the band 3 and bars 5 is bridged by the upper part of a member 4, the lower part of which directs the cigarettes towards a guide 6 which leads them to the bottom of a tray. A pivoted member 11 bridges the gap between the parts 4, 6 and rises to permit the passage of a tray. It drops back to the position shown as soon as the tray end has passed. The other end of the mass of cigarettes 7 is supported by a fixed member 12 and a number of oscillatory levelling members 13 which are carried by eccentrics 14 on a shaft 15 and are formed with slots 16 through which passes a fixed bar 17. The lower ends of the members 13 have rubber toes 18 which sweep over and level the cigarettes in the tray. The members 13 are swung out of the way of the tray end when the arm 23 is moved down the slot 24. The rubber toes then remove cigarettes resting on the upper face of plate-like members 2 which bridge the gap between adjacent trays. When a single tray is used to collect cigarettes from two machines, another set of feeding bars 21 is provided. A pivoted member 20 resting on the cigarettes 7 rises and falls as the level changes to vary the tray speed as described in Specification 649,467.

Title: Method of removing mercury vapour from gases
IPC: B01D53/64
Filed: 1971-06-21
Abstract: 1351950 Removing Hg vapour from gases SHOWA DENKO KK 21 June 1971 [23 June 1970] 28901/71 Heading C1A [Also in Division C7]  Mercury vapour is removed from a gas contaminated with the same (e.g. byproduct H 2  generated from a mercury electrolytic cell used for NaOH manufacture), by washing the gas with an acid solution containing persulphate ions, preferably at room temperature under atmospheric pressure. Suitable acids include H 2 SO 4 , HCl and HNO 3  and oxalic and sulphamic acids generally in a concentration of 10-30% by weight on the basis of the washing solution. The initial concentration of persulphate is preferably 0À5-1À5% by weight of the acid solution. Part of the oxidized Hg dissolves in the acid solution and the remainder is dispersed therein as a fine precipitate of mercury oxides. Liquid mercury metal is obtained from the spent washing solution by treatment with a reducing agent, e.g. SO 2 , Na 2 SO 3 , or hydroquinone.

Filed: 1962-07-30
Abstract: 973,669. Batteries. BADISCHE ANILIN- & SODA-FABRIK A.G. July 30, 1962 [Aug. 4, 1961], No. 29118/62. Heading H1B. Battery electrodes comprising porous, at least partly metallic grids containing as active material an oxidic compound of the grid metal are made by reacting the grids themselves with an aqueous solution of at least one salt of chromium, zinc, or aluminium, subsequently treating with an aqueous solution of an alkali metal hydroxide, e.g. potassium hydroxide, to form the active material, and rinsing the grids with water. The salts of chromium, zinc or aluminium are used in the presence of anions having an oxidizing effect such as nitrate or chlorate ions. A finely-divided nickel grid is treated with aluminium nitrate or chlorate to form nickel hydroxide as active material. Additional active material is formed by simultaneously treating with nickel (and/or cobalt) nitrate as in Specifications 487,607 and 331,540 to introduce active material into the grid pores.

Title: An improved inkstand
IPC: B43L25/10
Filed: 1930-09-30
Abstract: 357,377. Inkstands. PERRY, E. S., Athelney, Chislehurst Common, Kent. Sept. 30, 1930, No. 29240. [Class 146 (iii).] An inkstand having an ink container a is provided with a pen carrier o resting loosely upon but disconnected from the container so that it will readily leave the container, and an aperture q in the pen carrier is adapted to be closed by means of a penholder. An inkwell c provided at the centre of the container a may be connected to downwardly extending portions e of the container by means of webs g. A cover i for the container has a flange j formed with a small rib k which snaps below a rib h in the container a ; or the cover i may be screwed into the container. The cover i is formed with a central aperture l having a narrow upstanding bead m upon which rests the pen carrier o. The pen carrier has a downwardly extending part p fitting loosely within the aperture l in the cover i, and the central conical aperture q is adapted to be closed by the rounded lower end of a penholder which stands in a vertical position with the pennib projecting into, but not touching the bottom of, the inkwell c. Owing to the loose fit between the part p and the aperture l a lateral blow on the penholder will not upset the inkstand since the carrier will tip about the bead m. Projections or nibs d may be formed on the bottom b of the container a to indicate the correct level of the ink, and similar nibs n or a downwardly extending flange may be provided on the cover i. In a modification, the pen carrier, which may be of sheet metal, rests directly upon the upper edge of the container and itself forms the cover for the container as well as the pen carrier. The pen carrier has a downwardly projecting flange fitting loosely around the outside of the container. As shown in the Figure, feet f may be provided by cutting away the lower portion of the wall of the container. All the parts may be pressed from plastic material which is unaffected by ink.

Title: Improvements in or relating to the production of useful articles from coal
IPC: C04B35/528
Filed: 1945-11-08
Abstract: Articles are moulded from finely divided bituminous coal and fired to a temperature above 550 DEG  under non-oxidizing conditions. No binding agent or agent to prevent swelling is used and the firing is done at a rapid rate and preferably above 700 DEG C.  The coal should have between 13 per cent. and 22 per cent. volatile matter and a swelling number between 4 and 9.  The heating rate is between 1 DEG C. to 10 DEG C. per minute.  The article is moulded under pressure. The non-oxidizing atmosphere is obtained by packing in powdered coke or coal or passing a stream of hydrogen, carbon-monoxide, town gas, hydrocarbon vapours, ethylene or nitrogen through the furnace.  The pressure may be above or below atmospheric.  It is stated that the articles may be electroplated or glazed.  The articles may be subjected to a pore-filling treatment as described in Specification 593,079 or treated with a liquid monomer of one of the plastomers.
