Title: Improvements relating to web-turner bars for printing machines and for like purposes
IPC: B41F13/06
Filed: 1936-09-25
Abstract: 487,933. Feeding webs. SUTCLIFFE, E. R. Sept. 25, 1936, Nos. 26085, 29958, and 32050. [Class 100 (i)] The surfaces of web-turner bars used in printing or other machines are formed by a number of axially-movable elements a of a sector-shaped section, which move lengthwise with the web b as it passes over the bar and so lessen frictional effects and prevent set-off of printed webs. The sectors a are supported at their ends by ball-bearings c<1>, d<1> spacing them from the spindle c and sockets d fixed to the spindle respectively. Intermediate support may be provided by discs c<4> housed in axial slots c<3> in the spindle c. Ball-bearings are also provided between adjacent segments. As shown in Figs. 1 and 2, the sockets d are supported by ball races d<3> on studs carried by a U-shaped frame e on which is pivotally mounted a support for an inclined rubber belt h contacting with an enlarged end of the bar produced by securing strips a<1> of hard wood to the elements a and tending to return the segments to their normal position. A cam engaging rollers on the end of the bars a or on arms fixed each to a pair of bars may be employed for this purpose or springs or elastic cords pulling the bars towards one end may be used. The rotation of the turner-bar may be effected by the web or independently by a belt or chain passing over a pulley on the socket d. The outer surfaces of the elements a may have a greater curvature than that of the surface of the bar as a whole so as to present a smaller contacting area to the web. The elements may be of hollow metal construction.

Title: Improvements in or relating to fluid control valves and to fire-extinguishing installations for aircraft
IPC: A62C3/08
Filed: 1948-10-06
Abstract: 651,070. Fire-extinguishing systems. MACDONALD, I. G. Oct. 6, 1948, No. 26090. [Class 47 (ii)] [Also in Group XXIX] In a fire-extinguishing system on an aircraft, two valves 43, 44, Fig. 7, are mounted in adjacent engine nacelles 38, 39 respectively, the outlets 6 being interconnected by a pipe 45, while the outlets 5 lead to the respective engines and the inlets 4 are connected to extinguisher bottles 36, 37 respectively. The valves each comprise a flap 7, Fig. 1, spring-urged to close the inlet and adapted to engage one of two hinges 14, 15 slidable by a lever 18 so that inlet pressure moves the flap to close either outlet depending on which hinge is used. The lever is fixed to one end of a pin 19 movable by a lever 26, Fig. 6, connected through a link 27 to an armature 29 spring- urged to the position shown, in which the hinge 14 is engaged by the flap to close the outlet 6. Energization of a coil 33 aligns the armature between poles 32, thus moving the hinge 15 into engagement with the flap. Should a fire break out in one engine nacelle, e.g. 38, the pilot opens the bottles 36 and the fluid moves the flap of the valve 43 to cover the outlet 6 and flows through the outlet 5 on to the engine. If the fire is not extinguished, the pilot may energize the coil 33 of the valve 44, and movement of the armature causes an extension 48 of the link 27 to close a switch 50 which opens the bottles 37. The fluid moves the flap to close the outlet 5 and passes along the pipe 45, through the outlets 6, 5 of the valve 43 to the engine in the nacelle 38. It is stated that the outlet of one valve may be connected to the inlet of the other valve, whereby fluid from the inlet of the first valve may be directed to any one of three outlets.

Title: Improvements in and relating to the production of ferro-alloys and alloy steels
Inventor: PEARSON JOHN
IPC: C21C5/56
Filed: 1967-06-08
Abstract: 1,218,926. Refining alloys. BRITISH IRON & STEEL RESEARCH ASSOCIATION. May 31, 1968 [June 8, 1967], No.26560/67. Heading C7D. Ferro-alloys or alloy steels are refined by shattering a stream of the alloy or steel with a flow of oxidizing gas and collecting the droplets of molten alloy or steel, there being present in the starting melt an expendable material which is oxidized in preference to the other alloying elements by exothermic reaction with the oxidizing gas whereby the temperature of the droplets is raised to a level at which carbon present is oxidized in preference to the remaining other elements. The expendable material can be aluminium or silicon and lime can be added to the collecting vessel or dropped as a power alongside the descending melt stream to flux the silica or alumina produced. Application of the invention to refining of ferro-chromium, ferrovanadium, ferro-manganese and stainless chromium-nickel steels is described.
Patent GB-1069803-A (GB)
Title: Cleaning treatment process
IPC: B05B7/00
Filed: 1964-06-26
Abstract: In a process for scouring and or passivating e.g. boilers, tanks and exchangers by circulating a foam containing the required solution, the foam leaving the unit is collapsed by centrifugal action, recirculated, and refoamed.  Air or nitrogen is used to make the foam.  When an acid solution is used an anionic complexing agent is added and when alkaline an anionic oxidizing or complexing agent. Gluconate anions are used for dissolving calcium salts, fluoride anions for dissolving silica, and borate anion for sodium fluoride. Tartrate, malate, glycollate and amononium or amine citrate may also be used.  In an example an iron tank is scoured with a solution containing ethanolamine citrate and an emulsifier based on alkylsulphate and alkyl aryl sulphonate and then passivated with a solution containing 0.5% potassium chromate and 0.3% monosodium phosphate at a pH of 5.8. In a further example a boiler is scoured using ammonium bifluoride, formic acid and an emulsifier and passivated with borax and sodium nitrite.

Title: Improvements in or relating to electrical storage apparatus
Inventor: WILLIAMS FREDERIC CALLAND
IPC: H01J31/60
Filed: 1947-10-02
Abstract: 657,591. Calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 2, 1947, No. 26584. [Class 106 (i)] [Also in Groups XL (a) and XL (c)] In an information storing circuit of the type described in Specification 645,691, in which a cathode-ray beam strikes an insulating surface to produce a charge pattern, the beam is caused to irradiate a discrete area repetitively so that it assumes a particular state of charge, the beam being displaceable to irradiate an adjacent area to modify the charge on the first area. The circuit is described as applied to a system using a television type raster, each line comprising 32 ten micro-second intervals, each commencing with a micro-second "dot" which may be extended for a further four micro-seconds to form a "dash." It is shown that when an exploring beam approaches a " dot," a negative pulse appears in the associated pick-up means, whereas with a " dash " or line, a positive pulse first appears. A rectangular wave generator 10 feeds a divider 11 controlling the horizontal and vertical time-base generators 12, 13 and also controls the short " dot " and long " dash " pulse generators 15, 16. A pulse, appearing on the pick-up plate 7 is fed through amplifier 17 to a gate 18 which is opened for the duration of a " dot " by the strobe pulse generator 19. According to the sign of the pulse occurring during the strobe period, a pulse of " dot " or " dash " length is fed through the switch circuit 14 to the grid 3 of the cathode-ray tube, the beam remaining " on " for the appropriate period. New information may be entered over terminal 20 while the stored information is available at terminal 21. A non-linear timebase may be used allowing the beam to pause for the duration of a " dot," and the beam may be given a greater velocity between the termination of a " dash and the commencement of the next " dot." ' A third type of indication, a " short line," may be used having a length such as to give zero output when it is again scanned by the beam. As this length is critical, part of the raster is devoted to recording " short lines," the output of which is used to control the length of the " short lines '' to ensure zero output. In a modification, the beam is turned on in a defocused state. If a positive pulse results, the beam is focused, whereas with a negative pulse the beam remains in the defocused state. Various scanning arrangements are described to minimise the periods between the times when any given item of information is available.

Title: Improvements in and relating to the saccharification of cellulose-containing substances with mineral acids
IPC: C13K1/02
Filed: 1932-09-27
Abstract: <PICT:0386927/IV/1> In the saccharification of cellulose containing substances such as wood by means of mineral acids, such as hydrochloric acid, part of the acetic acid formed is recovered by withdrawing part of the liquor and treating it with water-retaining agents such as calcium chloride or sulphuric acid.  The liquor is passed from a storage container S to a compartment A containing calcium chloride solution and connected to a compartment B at RR<1>. At 130-135 DEG  C. the hydrochloric acid escapes to the condenser K and absorption vessels Q.  The calcium chloride solution now diluted flows through U into B and is there heated to about 150 DEG  C.  The water and acetic acid escape to the condenser K<1> and storage vessel V<1>, and owing to its increased specific gravity resulting from this concentrating treatment the chloride lye flows downwardly through RR<1> to A.  An intermediate vessel may be inserted in the conduit U where any hydrochloric acid carried along is given up.  Further the heat of the expelled hydrochloric acid may be recovered by a heat exchange with the inflowing mixture from S.

Abstract: 940,731. Mining-apparatus. S. GUREL. Nov. 20, 1959 [Aug. 20, 1958], No. 26826/58. Heading E1F. Breaking-down means comprises a pump operable by fluid pressure, e.g., compressed air, and having a low pressure stage and a high pressure stage with interposed valve means, a hydraulic breaking-down head being coupled directly to the high pressure stage. As shown, the breaking-down head 13 is secured to a high pressure stage 11 separated by manually set, slide-valve means 12 from the low pressure stage 10, the pump plungers 42, 28 are connected respectively to pistons 15, 20. The piston 15 is double acting and works in a cylinder 16 connected through a slide valve 17 with the compressed air supply 48. The slide valve stem 26 has a head 58 which is slidable in the hollow piston rod 28 and acts, at the ends of the reciprocations of the piston 15, to compress one or other of springs 57, 60. When the spring compression overcomes a spring pressed detent the slide valve 17 is moved to reverse the air admission and exhaust and the direction of the piston 15. The piston 15 thus reciprocates as long as the air admission valve 49 is open. The plunger rod 63 is attached to the piston rod 28 and works in a cylinder 68 to suck oil, through a non-return valve 60, from a reservoir cylinder 19 and force it past the spring-loaded valve 70 to the slide valve 74 which is adjustable either to admit the oil from the plunger 63, through the port 77, to the near side of the piston 20, whereby oil in the cylinder 24 is compressed to a still higher pressure by the piston 23, to force oil beneath the jack plungers 14; or to join the ports 77, 81 for the return of oil to the reservoir 19 whilst oil from the plunger 63 is forced through the passages 78 to the top of the jack plungers to return them to retracted condition. The jack plungers are protected by caps 84. A piston 18 is freely slidable on the sleeve 43 to follow up variations in the oil content of the cylinder 19.
