Title: Improvements in or relating to luminous electric discharge tubes
IPC: G09F13/26
Filed: 1930-05-13
Abstract: 353,967. Signs. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and RYDE, J. W., of General Electric Co., Wembley, Middlesex. May 13, 1930, No. 14732. [Class 3 (ii).] A sign comprises an electric discharge tube arranged in front of a diffusely reflecting background and provided with a colour filter which absorbs some of the visible radiation and causes the light received directly from the lamp to appear in a different colour from that reflected from the background. As shown in the Figure, the tubes 1 are coated on their front surfaces with a layer of coloured varnish 2, the light from the tube being reflected in its normal colour from the white background 3. Alternatively the layer 2 or a flat coloured screen may be arranged on the rear side of each tube, the letters then appearing in the normal coloured light of the tube while the background is illuminated in a different colour. Further effects may be obtained by colouring thebackground.

Patent GB-405165-A (GB)
Title: Process for the production of alkali phosphates
IPC: C01B25/30
Filed: 1933-05-26
Abstract: Alkali phosphates are obtained by heating in an aqueous medium phosphorus alloys, such as ferro-phosphorus, in the presence of an oxidizing agent such as air or oxygen, and an alkali hydroxide or carbonate or other alkali compound such as the aluminate, silicate phosphate or organic salt thereof.  When, for example, trisodium phosphate is employed, this is converted to the dibasic salt, which is then heated under pressure with sodium carbonate to obtain trisodium phosphate.  The conversion of the alloys may be effected in stirring autoclaves, temperatures of 150 DEG  C. and 200--300 DEG  C. being specified.  When carbon dioxide is evolved, this is removed by a current of gas, and may be condensed or solidified.  A statement of the prior art refers to the production of alkali phosphates by heating iron phosphate and alkali carbonate solution under pressure. The Specification as open to inspection under Sect. 91 comprises also the use of substances containing elementary phosphorus and describes the production of potassium phosphate.  This subject-matter does not appear in the Specification as accepted.

Abstract: Copper pyrites containing valuable constituents such as silver and molybdenite is roasted at a temperature not exceeding 500 DEG  C., regulated quantities of air being supplied during treatment and uniform composition of roasting gases being maintained, whereupon both iron and copper may be magnetically separated from the residue. The temperature range may lie between 430 and 470 DEG  C., and in the case of argentiferous fine ore 440 DEG  C. is preferable. The furnace is of the shelf type as described in Specification 255,432, [Class 51 (ii), Furnaces and kilns for applying &c.], and comprises a number of compartments 1 with hollow bottoms 2.  A vertical revolving shaft 6 is rotated by a gear wheel 8, the slot and key connecting them together enabling the shaft to be axially <PICT:0355664/III/1> displacable.  The material in the compartments is distributed by means of spiral-shaped rabbles 12 and falls from the upper compartment to the lower one through peripheral openings 15.  In this compartment the windings of the rabble are in the opposite direction so that the material is conveyed towards the centre from where it falls into the lowermost compartment through central openings 17. This compartment has a corresponding rabble and discharge openings to those in the uppermost compartment.  The furnace is heated electrically and may be heat insulated.  Air is supplied to each compartment from a main 24 and branches 25 having valves 26.  The gases issue through pipes 27 and regulating valves 28 to a common flue 29.  The draught in the latter is regulated by rotation of the pipe 33 which leads to a flue 36 containing a fan. Air is blown into the hollows of the bottoms from main 37.

Filed: 1920-06-10
Abstract: 168,981. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). June 10, 1920. Addition to 120,231. Breasting.-Instead of using the same knife for both roughing and finishing cuts, as described in the parent Specifi. cation, separate knives are employed operating at different positions in the machine, thus substantially reducing the time required for each heel. Heel blocks are fed by fingers 90, Fig. 2, to a station 10 on a rotating table which is turned one quarter revolution at a time so as to present the heel first to a vertically reciprocating knife 67, and then to a second similar knife 68 set in a little closer for a finishing cut. The knife 68 may, however, be at the same distance as the knife 67, the spring of the leather after the roughing cut being then relied on to allow of a finishing cut. At the position 15 the heel is forcibly ejected to a shoot. The knives 67, 68 are carried in a cross-head 60 reciprocated by a crank 62, Fig. 1, and connecting-rod 66. The table 8. mounted on a spindle 6, is rotated by ratchet gear 26 engaging a plate 20 operated by a main cam 34 through levers 32, 28 and a rocking shaft 30. A spring detent 40 is made to look the plate at each quarter revolution. The heels are held on plates pivoted at 12 to the table and adjusted by a screw collar 16. The heels are fed from a magazine 70 by a reciprocating. slide 106 carrying the aforementioned fingers 90. The slide is operated by arms 114 connected to a bell-crank 116 operated by a pin 122 on the vertically moving knife-carrier 60. As the knives descend, a heel is fed against a spring 150 beneath a clamp 166. The clamp is spring-pressed but is held up by trip gear 190 to allow the passage of a heel. As soon as a heel is in place, the clamp 166 descends and holds the heel till a cam roller 170 engaging a fixed cam path 172 lifts the clamp and the heel is forcibly ejected by the spring 150. The heels above the lowest in the magazine are held against downward motion by an oscillating finger 134 cam-operated at 139. The pile of heels partially overhang the table 8. Specification 144,716 is referred to.

Abstract: 936,945. Filters. MINE SAFETY APPLIANCES CO. April 25, 1962, No. 15726/62. Class 8(2). A method of making a filter element, Fig. 1, comprises transversely folding a long strip 2, Fig. 4, of flexible filtering material back and forth upon itself to form a stack of sheets 4, 5, 6 while successively joining each pair of adjoining sheets together along each line 8 of a row of laterally spaced lines that extend lengthwise of the strip, the lines in each row other than the end rows being staggered relative to the lines in the rows at immediately opposite sides of that row, applying pressure to each end sheet of the stack along laterally spaced lines opposite to the joining lines 8 at the inner side of the sheet so as to form waves 11, Fig. 6 (not shown), in the end sheets, joining a pair of panels 14, Fig. 7, to the end sheets along the crests of their waves while still maintaining the pressure, releasing the pressure, and then pulling the panels 14 apart to separate the unjoined areas of all the sheets to form filter pockets 16 between the sheets. The pressure is applied to the end sheets by rows of rods 10 which are pressed into the sheets by clamps 13 through bars 12 extending transversely of the rods; the rods are subsequently removed. The adjacent sheets may be joined together by stitching or stapling but are preferably joined by adhesive and each line may be made up of a row of dots. After the panels 14 are pulled apart a further pair of panels 15 are inserted between the panels 14 to complete a frame for the element, the panels 15 thereafter being sealed to the sheets. Specification 870,972 is referred to.
