Abstract: 824,648. Electron beam deflecting apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 12, 1956 [June 20, 1955], No. 17818/55. Class 39(1). A cylindrical reversing lens with a U-shaped optical axis, consists of a central spine 14, Figs. 2 and 3, a repeller trough 15 and positive flanking electrodes 13 all having curved profiles in planes parallel to the incidence and emergence planes of the electron beam which is deflected by a pair of plates 16 and has the property of increasing the deflection angles. The deflection plates 16 may be designed to focus the beam simultaneously in both X and Y directions at all angles of deflection. In Fig. 4, channel shaped plates 16<SP>1</SP>, 16<SP>11</SP> are combined with further plates 17<SP>1</SP>, 17<SP>11</SP> at the mean potential of the X deflection wave. The curvatures and shapes of the various electrodes of the lens system are discussed from the point of view of reducing aberrations and to ensure that a plane fan of rays entering the lens emerges plane. The effect of the spacing between the incident and emergent branches of the optic axis decreasing with increasing deflection angle can be compensated by thickening the central spine electrode 14 at its ends, or by increasing the width of the repeller trough 15, according to a parabolic law. The lens electrodes may have concave curvature in some applications. Specific examples are given. The system is composed with the plane mirror system of Specification 739,496 is applicable to the "flat" tube of that Specification, or to A-scope radar presentation systems.

Title: Improvements in and relating to transport systems for particle form material
IPC: F23J3/02
Filed: 1959-05-26
Abstract: 853,653. Cleaning heat-exchangers. BABCOCK & WILCOX CO. May 26,1959 [May 26, 1958], No. 17981/59. Class 99(2)..[Also in Group XXIX] A transport system, a shot cleaning system for a heat-exchanger, for particle-form material includes a closed vessel having an entry for pressure fluid, an outlet through which material contained within the vessel is dischargeable by the pressure fluid and an inlet for the gravitational movement of material into the vessel under the control of a valve having a pivoted closing member 28 rotatable in a downward direction from a closed or seat-engaging position to an open position, and an operating element 37 arranged when moved in one direction to a valved closed position to act through cam means 36 to urge the closing member against its seating 27 and when moved from the valve closed to a valve open position positively to ensure rotation of the closing member to its open position. As shown, the element 37 is U-shaped in form and mounted on coaxial shafts 40, 41, the shaft 41 being connected to the piston rod of pneumatic piston-cylinder device 45. Pressure fluid is delivered to pipes 30, 31 adjacent the seat 27 so that the latter is swept by fluid before closure of the valve. The flow of fluid to the valve 20 is regulated by a flowcontrol valve 56 in the supply pipe 55 and connected with an electrically-operated four-way timer valve 58 from which pipes 60, 61 lead to opposite ends of the cylinder 45. Fluid passing through the pipe 60 to the cylinder causes the member 28 of the valve to move to the closing position thereof, and fluid passing through the pipe 61, which has inserted therein an adjustable valve 62, actuates the device 45 to close the valve. During the closing period of the valve regulated by the valve 58, the exhaust fluid through the pipe 61 is restricted by the action of the valve 62 to delay closing of the valve by an adjustable amount. Simultaneously with the application of fluid pressure to the device 45 and through the pipe 60, fluid pressure is applied to the valve 56 so that fluid flows through pipe 55 to the pipes 30, 31.

The phosphite esters may be prepared by a transesterification reaction between pentaerythritol and a trialkyl phosphite, e.g. triethyl phosphite or triisopropyl phosphite.  Specified phenols include phenol itself, chlorophenol, resorcinol, p-phenylphenol, phloroglucinol, hydroquinone, cresol, m-xylenol, b -naphthol, coal tar and coal hydrogenation fractions, bis-phenols and the trinuclear phenols such as 1,1,3-tris(p-hydroxyphenyl) propane, 1,1,3-tris(hydroxytolyl) propane, 1,1,3-tris(hydroxyphenyl) propene-2 and 1,1,3-tris(hydroxyphenyl)-2-methyl propane.  The resin-forming reaction mixture usually includes an acidic catalyst such as sulphuric acid, hydrochloric acid, toluenesulphonic acid, benzenesulphonic acid, boron trifluoride, aluminium chloride, dialkyl sulphates, titanium tetrachloride, phenyl acid phosphate and octylphenyl acid phosphate.  In a modification, the 3,9-dialkenylspirobi(meta-dioxane) and phenol are reacted in the presence of an acid catalyst to produce a liquid pre-condensate A-stage resin which is then reacted with the partial phosphite ester of pentaerythritol also in the presence of a catalyst.

Abstract: 852,459. Boring, milling and facing-machines. NEW BRITAIN MACHINE CO. May 27, 1959 [Nov. 13, 1958], No. 18036/59. Class 83 (3). In a boring, drilling, and/or milling- machine, the tool-spindle is fed by a lead-screw, and the tool-holder is secured in a socket in the spindle by a spring-urged collet, and released when the collet is moved against the spring by a number of fluid-operated pistons in tandem. The spindle 16 carries a tool-arbor L locked by an axiallymovable split collet 37 which engages a double conical projection 34 on the arbor and a bevelled bush 50 in the spindle, the collet being urged to the left by springs 51 which engage a projection 40 on a draw-bar 38 connected to a tubular draw-bar 41. The faces 46, 47 of the arms 45 of the collet 37 converge to the left so that when the draw-bars 41, 38 are moved to the right by fluid-pressure means, the projection 34 is released and an ejector 52 on the draw-bar 38 disengages the arbor from the socket 24. The fluid-pressure means consist of pistons 55, axially-spaced on a sleeve 56 by spacers 58 and nut 60, the sleeve being axially slidable on a member 61 carrying backlash-preventing nuts 19, 20 engaging with the lead-screw 17. To move the drawbars 41, 38 to the right, fluid passes ' from a solenoid-operated valve 74 through a pipe 72, an aperture 67 and ports 07 on to the left-hand faces of the pistons, thus moving the end of the sleeve 56 into engagement with a collar 76 on the left-hand end of the draw-bar 41, and the collet 37 is disengaged from the arbor L. Before the spindle 16 is rotated by gears (not shown), fluid-pressure is applied automatically, by means not shown, to the right-hand faces on the pistons through pipe 73, aperture 68 and ports 71, for a short period in order to disengage the rotating collar 76 and the non-rotating sleeve 56. The leadscrew 17 is rotatably located against axial movement in the spindle head C and is rotated through gears K.

Abstract: 274,492. Compagnie de Bethune. July 17, 1926, [Convention date]. Methanol and other alcohols.-The synthesis of alcohols, particularly methyl alcohol, by the interaction of carbon monoxide and hydrogen at elevated temperature and pressure is effected with catalysts prepared by depositing the formates of metals giving irreducible oxides upon a porous support, such as pumice, asbestos, charcoal and activated carbon. Uranium, tungsten, vanadium, zinc, glucinum, chromium and titanium are specified as suitable metals. According to the examples, active carbon is heated to redness, immersed in a solution of zinc formate or a mixture of zinc and chromium formates, and the solution evaporated to dryness. The yields obtained by the use of these catalysts under certain conditions are contrasted with that obtained by the aid of a dried paste of zinc oxide mounted upon pumice. The Specification, as open to inspection under Sect. 91 (3) (a), refers generally to soluble salts of metals giving irreducible oxides. This subject-matter does not appear in the Specification as accepted.
