Title: Improvements in or relating to apparatus for manufacture of granule coated webs
IPC: B24D11/00
Filed: 1935-04-25
Abstract: 455,640. Granule-coated webs. ABBEY, A., 111, Hatton Garden, London.-(Carborundum Co. ; Niagara Falls, New York, U.S.A.) April 25, 1935, No. 12466. [Class 60] [See also Group XXXV] Apparatus for making granulecoated webs comprises a magnet system having oppositely arranged poles, means for supporting an adhesivecoated web in the field between the poles and means for supplying granules into the field adajacent to the coated surface of the web, so that the granules are magnetically oriented and projected on to the web. Paper or cloth P passes from a roll 2, Fig. 1, between printing rolls 4, 5 and thence in contact with idler rolls 7, 8, 9 to adhesive applying apparatus 11, 12, 13. The adhesive coating is smoothed by a vibrating brush 16 and the web is guided by idler rolls 18, 19, 20 into the field between electromagnets 22, 26. Granules are distributed from a hopper 35 on to an endless belt 41 which moves through the magnetic field beneath the web P. Upper and lower polepieces 24, 25 of the electromagnet 22 are positioned so that the web P is nearer the upper polepiece 24 so that the granules are propelled upwards on to the web. The upper and lower polepieces 28, 29 of electromagnet 26 are symmetrically and evenly spaced from the web P and are shaped to produce a distributed magnetic field which is relatively stronger at the part adjoining the field of magnet 22 and of gradually decreasing intensity at the part remote therefrom, to ensure that the granules remain vertically oriented as the web passes out of the magnetic field. The adhesive coating is preliminarily set by air from a blower 48 and the coated web then passes over an idler roll 49 and suction drums 51, 52 to a drying rack 55. In the modification shown in Fig. 3, granules supplied from a hopper 35 fall by gravity into the magnetic field from electromagnet 71 having polepieces 73, 74 similar to those of magnet 26, of Fig. 1, and are deflected towards the web by a member 78. The coated web is immediately passed around a roll 76 so that the orientation of the granules is not destroyed by gravitational attraction. If the granules are insufficiently magnetic they may be coated first with a lacquer or varnish and then with magnetic material such as iron or magnetic iron oxide.

Title: Process for the production of ceramic spheroids
IPC: G21C3/62
Filed: 1971-04-30
Abstract: 1322814 Spheroids of metallic oxides and carbides GES ZUR FORDERUNG DER FORSCHUNG AN DER EIDGENOSSISCHEN TECHNISCHEN HOCHSCHULE 30 April 1971 [1 May 1970] 12480/71 Heading C1A [Also in Division G6] Ceramic spheroids are produced by dispersing droplets of an aqueous sol of a metallic oxide, or a mixture of a metallic oxide (e.g. uranium oxide) and carbon in a liquid medium (e.g. petroleum ether, decane or trichloroethylene) whose temperature is below 0‹ C. so that the droplets are frozen and gelled with the aid of an alkaline gelling agent present in the liquid. The droplets are maintained in suspension until frozen and are removed from the liquid and heated at a temperature at which sintering of the oxide or reaction of the oxide and carbon occurs to form the ceramic spheroids. The liquid medium may be made alkaline by bubbling ammonia in from the bottom upwards through the liquid medium. The sol may be added through a nozzle which projects into the liquid medium. The density of the liquid medium is preferably less than the mean density of the sol. Prior to the heat treatment, the gelled droplets, which have been separated from the liquid medium, may be contacted with an ammonia solution and dried. The process may be continuous.

Title: Improvements in or relating to electrical impedance transformers for use at very high frequencies
IPC: H01P1/24
Filed: 1951-05-29
Abstract: 683,273. High-frequency impedance transformers. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 29, 1951 [June 1, 1950], No. 12575/51. Class 40 (viii). An impedance transformer comprises two wave-guides 1 and 2, each closed at one end by an adjustable piston 3 or 4, and directively intercoupled so that a wave entering one guide divides into travelling waves of equal amplitude in each guide. The pistons are operated by a differential screw 12 which moves them equal distances in opposite directions, and by a screw 11 which moves them equal distances in the same direction. Calculation shows that operation of screw 12 varies the amplitude of waves emitted from the transformer and screw 11 varies their phase. The ends 5 and 6 of the guides serve as inlets and outlets for the apparatus and the end 6 may be provided with a reflectionless termination 22.

Abstract: 888,890. Tracks for toy vehicles. EINFALT, A., and EINFALT, J., [trading as EINFALT BLECHSPIELWARENFABRIK GEB.]. April 14, 1959 [Feb. 21, 1959], No. 12634/59. Class 132(3)  A collapsible toy track comprises a section b hinged at n to a section c provided with teeth for engagement by a toothed driving wheel of a traction vehicle q. A level track section e has a portion # hinged to it and the portion # is normally spring urged to a substantially horizontal position. The first section h of the return part of the track is hinged at m to a track portion i which runs into the track section b. A waggon p is coupled to the traction vehicle at a starting station a and as the vehicles reach an intermediate station o, the forward end of the waggon is lifted by cams r formed on the inside of the walls of the station. The waggon is thus uncoupled and runs back over the sections c, b, to the starting station. The traction vehicle continues on and moves on to the track portion # which is momentarily depressed so that the vehicle rolls on to the return track sections h, i. The track section c is raised by the vehicle which then travels on the section b to the starting station where the two vehicles are automatically recoupled ready for further operation. The mechanism of the traction vehicle may be spring driven and a member j in the waggon is reversible so that two different loads, e.g. coal or gravel may be represented. The hinged connections at m and n comprise plates 1 having projections 2 which engage in edge portions 6 of the track. Fig. 3 shows how the track may be collapsed for packing.

Title: Improvements in and relating to steam power producing plant
IPC: F03G7/05
Filed: 1946-04-26
Abstract: A power generating system (see Group XXVI) has three vapour streams at different pressures leaving the turbine that enter into condensers 53, 57, 58 through openings 62, 61, 60 respectively. Cooling water is pumped to a conduit 45 from which it flows into a chamber 50, maintained at reduced pressure for degassing purposes, and then flows on to the perforated plate 52 and drips into condenser 53 where it mixes with, and condenses, the vapour and flows through pipes 56 on to the plate 52 of the condenser 57; the water in the pipes 56 forms a seal between the two condensers which are <PICT:0624618/III/1> at different pressures.  The water flows in similar manner through condensers 57, 58 and finally into sump 69 which is emptied by a pump.  Specification 610,786, [Group XXVI], is referred to.

Title: Back siphonage prevention, anti-backflow and vacuum breaking valve and method of operation
IPC: E03C1/10
Filed: 1944-07-04
Abstract: 586,166. Fluid - actuated valves. CARLTON, F., and SNYDER, L. L. July 4, 1944, No. 12724. Convention date, June 22,. 1943. [Class 135] A valve arrangement for preventing backflow or back-siphonage in a pipe system, such as the domestic supply of water to a building or the supply of water to an industrial plant, comprises a valve C actuated by a double diaphragm 49, 50 to control the flow from the inlet 33 through chambers 42, 611 and 88 to an outlet 122<1>. The inlet pressure acts on the diaphragm 49 to open the valve C whilst the outlet pressure from 1221 acts through a pipe 129 above the diaphragm 50 tending to close it. The effective area of diaphragm 50 is greater than diaphragm 49 so that a pressure differential is maintained across the valve. From chamber 61<1> to the outlet the flow passes a normally open valve E and a hinged check valve B, both of which close on back-flow conditions occurring, together with the valve C, the valve E being actuated by the outlet pressure acting through a pipe 130 on a diaphragm 101 against the inlet pressure on a diaphragm 104 through pipe 131, these diaphragms being secured to a tubular member 74 which carries the valve E. This member 74 also carries a relief valve F which opens to relieve any pressure in chamber 88, by leakage past check valve B, when the valve E is closed. Under these conditions an air intake valve D co-operating with the top of tube 74 is also opened to place the chamber 61<1> open 'to atmosphere through a pipe 141. Thus, any possibility of back-flow from the outlet 122<1>, which may be contaminated, to the supply line 33 is prevented. A vacuum breaking valve A for the supply line is also provided which comprises a sleeve member 18 supported by a diaphragm 16 and seating on a seat 20, and also carrying a check valve 38. The inlet pressure acts on one side of this diaphragm to maintain the valve 18 closed, but the other side of the diaphragm is open to atmosphere through openings 23 so that in the event of sub-atmospheric conditions existing in the line 33, the atmospheric pressure acts on the diaphragm 16 to open valve 18 to relieve such conditions. If any vacuum in line 33 should extend to chambers 42 and 61<1> it will be relieved by the air intake valve D.

Title: Pressure measuring device
IPC: G01L9/00
Filed: 1948-05-12
Abstract: 672,879. Electric measuring systems. FOXBORO CO. May 12, 1948. [May. 14, 1947] No. 13054/48. Class 40 (i). [Also in Groups XIX and XXIX] Pressure measuring apparatus comprises a flexible diaphragm 46 responsive to a variable pressure and mounted in a casing 14, a tube 18 fixed to the casing at one end but readily detachable therefrom, a comparatively rigid rod 64 extending through the tube and fixed to a point thereon remote from the fixed end, and electrical signal transmission means responsive to the magnitude of the lateral deflections of the tube by the diaphragm for producing a signal substantially proportional to the value of the variable pressure, the diaphragm being separate from the rod and tube so that the latter elements can be removed from the casing without disturbing the diaphragm. The variable pressure may itself be the ultimate variable, or it may be indicative of another variable such as fluid flow or liquid level. In the latter case, the pneumatic pressure produced by variations in the liquid level in an air vessel is utilised. In Fig. 1, the fluid flow in a pipe 10 is indicated by a pneumatically-operated recording controller 32 which also regulates a pneumaticallyoperated valve 12. The flow is also measured electrically by a strain gauge 122 fixed on the tube 18. The pressure difference 'across a restricted orifice 16 is applied to the ends of the casing 14 which comprises two sections 42, 44 between which the diaphragm 46 is clamped. The adjacent end walls 52, 54 of the sections are corrugated like the diaphragm and protect it against pressure differences outside the normal operating range. The tube 18 is secured in the section 44 by a threaded bushing 62 and its upper end is secured to the rod 64 bv a nut 70 which supports a rod 22 movements of which control a pressure converter 22 (see Group XXIX). The diaphragm 46 carries a knife edge 75 bearing against the rod 64. The pressures on opposite sides of the orifice 16 act on the remote sides of two slack diaphragms 84, 106, the spaces 74, 100 between these diaphragms and the diaphragm 46 being filled with a liquid such as kerosene through passages 114. 118 closed by plugs 116, 120. The strain gauge element 122 may be as described in Specification 549,140 and comprises a resistance wire 124, Fig. 6. The wire 124 is connected in a Wheatstone bridge circuit with fixed resistances 134, 136 and a variable resistance 138. The resistance 138 is varied bv turning a knob 150 having a pointer 152. The knob 150 is adjusted until the needle 144 of the galvanometer 140 returns to its null point 148. The reading of the pointer 152 on a scale 154 is then taken. The scale 154 may be calibrated in terms of differential pressure. For more accurate measurement, apparatus as described in Specifications 646,981 and 647,025 may be used. The variations in the resistance of the strain gauge element. may be used to control the flow in the pipe 10. Ina modification, the slack diaphragms 84, 106 are dispensed with.
