Title: A new or improved machine for weighing and filling powdered, granular or like materials into receptacles
IPC: G01G13/00
Filed: 1927-05-20
Abstract: 271,498. Maillefer C. May 21, 1926, [Convention date]. Automatic-feed weighers. - In a machine for filling receptacles with weighted quantities of powdered or granular material of the kind comprising a series of measuring-devices of graduated capacities, and a series of balances co-operating therewith the balances are movable relatively to the measuring-devices and are each adapted to be brought to rest under each measuring device in succession, commencing with that of the largest capacity. As shown, a series of balances 6 is radially disposed on a circular platform 4 that is mounted on a vertical spindle 2 and is adapted to be rotated through a worm gear 3. Each balance is provided with two weigh-pans, the outer 6b for the reception of a receptacle and the inner 6<c> for weights. Arranged in fixed position above the outer weigh-pans are a series of measuring- devices 7 that are fed with material through a main shoot 11 and subsidiary shoots 12. Each measuring device comprises a cylindrical casing, Fig. 3, containing a compartmented wheel 7b that is adapted to be rotated through.a quarter of a revolution as the balances are moved from one measuring-device to the next. The capacities of the measuring devices are graduated in such a manner that the receptacles receive gradually decreasing charges as they pass round the machine. The number of the measuring-devices is less than that of the balances thus leaving a space for the operator to replace the filled receptacles by empty ones. A ring 5 is provided with projections 5a which engage the legs of the weigh-pans, and prevent oscillation of the balances due to the momentum of the falling material. The measuring-devices are actuated by pawls 16, Fig. 4, which are pivoted to a ring 17 rotatable with the balances and are adapted to engage pins 15 projecting from a disc 14 connected to the wheel 7<b>. When a receptacle has received the required weight, the balance tilts and a blade spring 21 contacts with a ring 22 thus energizing an electromagnet 18, Fig. 4, and rotating into inoperative position the pawl 16 of the next measuring-device.

Title: Improvements in or relating to processes and apparatus for eliminating hydrogen sulphide and other noxious impurities from fuel gases, and from air
IPC: C10K1/12
Filed: 1924-06-05
Abstract: 240,891. Jackson, W. J. Mellersh-, (Koppers Co.). June 5, 1924. Sulphur.-Hydrogen sulphide and other impurities are transferred from a gas to a stream of air which is washed with a liquid containing an iron compound wherebv the hydrogen sulphide in the air is decomposed, the air washing liquid being regenerated by treatment with air. This removal of the impurities from the air may be applied to air whatever its origin. The gas to be treated enters a washer 1 by an inlet 3 and escapes by an outlet 14 and is treated therein with an aqueous solution of an alkaline compound such as sodium carbonate entering from a pipe 2 the foul solution passing into a sump 4 and being treated with air in a tower 6, the regenerated solution being pumped back from a sump 8 to the washer 1. The air supplied by the blower 7 when charged with hydrogen sulphide, carbon-dioxide and hydrogen cyanide is passed by a pipe 9 to a washer A in which it is treated with a suspension preferably in an alkaline solution of an iron compound which absorbs and oxidizes the hydrogen sulphide in the presence of the air to free sulphur. An air agitator 10 assists the reaction. Any sodium thiosulphate formed may be recovered by the means described in Specification 209,169. Suitable iron compounds are ferric or basic ferric carbonate, ferric oxide or hydroxide, ferrous oxide or hydroxide or ferrous carbonate. The alkaline solution may be sodium or potassium carbonate or hydroxide or similar magnesium or calcium compounds. Alternatively, the iron oxide may be suspended in water. Specifications 169,996 and 170,572, [both in Class 55 (ii), Gas manufacture &c.], also are referred to.

Title: Improvements in radiography
Inventor: SCHAFFERT ROLAND MICHAEL
IPC: G03G5/082
Filed: 1951-06-11
Abstract: 721,944. Xeroradiography. BATTELLE DEVELOPMENT CORPORATION. June 11, 1951, No. 13800/51. Drawings to Specification. Class 98 (2). The invention is concerned with the application of xerographic techniques to radiography. Thus an electrostatically-charged X-ray sensitive amorphous or α-monoclinic selenium surface layer on a plate is exposed in the dark to penetrating radiation, e.g. X-rays, #-rays, while an object to be radiographed is positioned between the radiation source and said layer, thereby producing a charge pattern image on said layer, and developing such image to make it visible by applying a finely-divided material to the image. The selenium layer may charged by corona discharge and the developer may be a powdered artificial resin mixed if desired with a granular carrier material, while exposure may be effected by using penetrating and non- penetrating, e.g. light, radiations simultaneeously. The powder image may be fused on to the plate or transferred to a separate support, e.g. paper, either by electrostatic action or by contacting the powder image with a solventmoistened receiving paper sheet. Reference has been directed by the Comptroller to Specifications 658,699 and 679,715.

Filed: 1941-10-30
Abstract: 560,894. Relaxation oscillators. BRITISH THOMSON-HOUSTON CO., Ltd., and MILWARD, V. E. Oct. 30, 1941, No. 13996. [Class 40 (v)] [Also in Group XXXVI] A circuit arrangement for obtaining short linearly-rising voltage impulses comprises a condenser charged through a resistance from a source consisting of an inductance through which flows the discharge current of a second larger condenser, whereby the voltage across the inductance is substantially constant for the impulse duration, the discharge of the second condenser being effected through a controlled arc discharge device. Negative voltage, derived across condenser E by rectification from an A.C. supply 12, is applied through an inductance B3 and resistance 19 to a condenser A3 which is thus charged to a higher voltage than that supplied across E. The condenser A3 is discharged through an inductance B1 and an arc discharge device 22 when a synchronizing pulse is applied to its control grid. For the initial portion of the discharge, the voltage across the inductance B1 is substantially constant and is used to charge the condenser Al through a resistance 9, producing a linearlyrising voltage across the condenser A1 which is applied through a condenser 23 to the deflecting plate D1 of the cathode-ray tube C. A coil B2 coupled to the coil B1 produces an equal and opposite voltage across the condenser A2 which is applied to the opposite plate D2 of the tube C. The wave-form to be examined, preferably short square-topped pulses, is applied to a second pair of plates D3, D4.

Abstract: 1,141,263. Cutting-apparatus; seaming non-metallic sheet material. DOUGHBOY INDUSTRIES Inc. 30 March, 1966 [22 Nov., 1965], No. 14054/66. Headings B4B and B5K. [Also in Division B8] The bottoms of bags are formed from tubular thermoplastic film R by gripping and transversely sealing the tube at a station 24, and flowable material is then poured into the tube at a station 23 from a shoot 37 carrying a knife-edge 35 which first cuts a transverse slit in the tube wall (see Division B8). Bag forming and separating.- At the station 24 the tube is gripped between reciprocating jaws 64, 65, spring-biased arms 88, 89 being provided to smooth the tube flat. Heaters (79, 80), Fig. 2 (not shown), mounted above and below the jaw (64), heat-seal the opposed tube surfaces together, thereby forming respectively the bottom of a bag to be filled and the top of an already filled bag. Strips of slippery, heat-resisting material (79b, 80b), Fig. 3 (not shown), are mounted above and below the jaw (65) to act as anvils for the heaters. Cooling water passing through tubes adjacent the heaters cools and hardens the seams so formed. Blades 69, 70, mounted on endless chains 71, Fig. 4, above and below the jaws then sever the tube completely in two spaced lines, separating the previously filled bag from the newly filled one. The drive to the blades 69, 70 is from a sprocket 75 mounted on a slide 74 and co-operating with a fixed chain 73. The slide 74 is driven along a rail 67b by and arm 74a, and accelerated motion is transmitted to the chain 71, and thus to the blades, through the sprocket 75. One of the lines of the cuts may be in the same line as that of the filling slit (25<SP>1</SP>), Fig. 11 (not shown), or the slit may alternatively lie between the two cuts. Control.-The moving parts of the apparatus are operated through a series of cams synchronized with the tube feed control, which may include a sensing means to detect marks on the tube corresponding to the required length of bag. Alternatively, a predetermined length of tubing may be fed automatically at each stage.
