Title: Machine tool for spherical turning
IPC: B23B27/12
Filed: 1972-03-07
Abstract: 1371265 Machining spherical surfaces LENINGRADSKY METALLICHESKY ZAVOD IMENI XXII SIEZDA KPSS 7 March 1972 10596/72 Headings B3T and B3B A machine tool for turning spherical surfaces comprises a faceplate 2 on which a workpiece is mounted a tool carrying lever 6 having a ball and socket connection 5 between one end of the lever 6 and a support 4 mounted on the faceplate, the geometric centre of the ball and socket lying at a point on the axis of rotation of the faceplate. A traversing arm 10 is pivotally connected intermediate the ends of the lever 6 and a rotary cutting insert 19 at the other end of the lever. The traversing motion of the arm 10 pivots the lever 6 about the ball-and-socket joint whereby the cutting insert 19 moves in an arcuate path across the surfaces of the rotating workpiece. The cutting insert is inclined to the direction of movement of the lever so as to promote selfrotation of the insert. The control of the rotation of the insert is effected by a rope and pulley system 21 to 24 to permit one revolution of the cutting insert during one pass of the tool across the surface of the workpiece. Figs. 1 and 2 show respectively apparatus for machining internal and external surfaces.

Abstract: 1397781 Fluid regulation UNITED KINGDOM ATOMIC ENERGY AUTHORITY 14 Feb 1973 [8 March 1972] 10872/72 Heading G3H.  A vortex amplifier has fixed vanes or angled jets at the main fluid inlets M 1 , M 2 , M 3  for delivering main flow into the vortex chamber with a pre-spin, and at least two control flows delivered through respective valved passages C 1 , C 2 , C 3  in a direction opposing the pre-spin, the arrangement being such that spin imparted by full flow through any one of the control passages can be cancelled by the prespin. Thus if one of the control valves V 1 , V 2 , V 3  should fail in a fully closed or partially open position, flow through the remaining valve or valves may be increased to provide the necessary control, or if the valve fails in a fully open position the prespin is cancelled by the flow through the failed valve and control is exercised by operation of the remaining valve or valves.

Title: Anti-corrosion compositions
IPC: C09D5/08
Filed: 1955-04-15
Abstract: An anti-corrosion composition for buried or exposed metalwork comprises a dispersion of tannin in a water-resistant neutral greasy carrier, e.g. petrolatum or a similar product obtained by mixing mineral oils and waxes or lanoline.  An inert siliceous filler such as talc, china clay, slate powder or inert earths may be included.

[Class 100 (ii).] A coating composition for stencil sheets comprises a potentially reactive phenol condensation product of the type known as Baekeland's product B and modifying agents, the coated base being dried and heat treated to convert the product to the insoluble and infusible form of the type known as Baekeland's product C. The modifying agents may comprise shortening agents, which render the coating less tough, and tempering agents. The following are mentioned as suitable modifying agents:- metallic soaps, e.g. aluminium stearate; a wax, such as China wax or paraffin wax; Japan wax, Chinese tallow, or ordinary animal tallow; zinc oxide, barium sulphate, carbon, lithopone, or carbonates, such as magnesium carbonate. The tempering agent may comprise an oil or fat, such as a mixture of dibutylphthalate and neatsfoot oil, neatsfoot oil alone, or hydrogenated cottonseed oil. Colouring matter may also be added to the composition. In a specific example, the composition comprises, in addition to the product B, melted paraffin wax, aluminium stearate, neatsfoot oil, dibutylphthalate, and colouring matter dissolved in toluol, ethyl or butyl alcohol, or other solvent. The coated sheet is subsequently baked in an oven. The paraffin wax may be omitted, the proportions of the remaining ingredients being varied. A second example comprises the condensation product, aluminium stearate, and hydrogenated cottonseed oil.

Title: Emergency lighting systems
IPC: H02J9/02
Filed: 1972-03-10
Abstract: 1432342 Emergency lighting systems D M LONGDEN 24 May 1973 [10 March 1972] 11192/72 Heading H2H An emergency lighting system comprises an emergency source of illumination and an emergency source of power together with means to connect the emergency source of power to the emergency source of illumination when the mains source of power to the main source of illumination fails. When the main source of illumination (not shown) is energized by a main source of power the main source of power also causes energization of a relay 5. Contact 7 of this relay is then closed and the contact 6 opened, thus the emergency source of power, i.e. the battery 1, is disconnected from the emergency source of illumination, i.e. the lamp 2 and at the same time a relay 8 is energized from the mains source by way of a transformer 3 and rectifier 4 so as to close the contact 10 whereby the battery 1 is charged from the main source of power. Should the main source of power fail, the relay 5 is de-energized whereupon contact 6 closes, contact 7 opens, the relay 8 however being maintained energized by the battery 1 so that contact 10 remains closed thus the lamp 2 is energized by the battery 1. The lamp 2 may be an incandescent or a fluorescent type. Should the emergency source of illumination not be required at any time when it is energized, opening of a push button type switch 9 de-energizes the relay 8 to open the contact 10. Re-setting of the relay 8 takes place when the main source of power returns. Transistors may be used in lieu of relays.
Patent GB-768695-A (GB)
Title: Improvements in and relating to evaporators
IPC: B01D9/00
Filed: 1954-04-15
Abstract: <PICT:0768695/III/1> In an evaporator 1 which has a heating belt with vertical tubes 4 and a thermally-insulated downcomer 5 passing through the belt, this downcomer extends below the lower tube-plate 3 so that its outlet is close to the base of the evaporator.  The apparatus is adapted to produce crystals of uniform medium size by evaporating a solution.  The downcoming circulating liquor deposits the larger crystals in the base of the evaporator, while the smaller crystals recirculate up through the vertical heating tubes. Ammonium sulphate is referred to.  The space between the double-walled pipe comprising the downcomer may be packed with insulating material, or it may be airfilled, or partially evacuated.  The larger and heavier crystals which collect in the conical base of the evaporator, are passed together with liquor through valve 9 and pipe 10 into crystallizing chamber 11, which is surrounded by a thermostatically-controlled steam or hot-water jacket 12.  Further crystallization takes place in chamber 11, and large crystals collect in the base.  These crystals together with liquor are conveyed by ejectors 15 to the hopper 17 of a centrifuge.  Liquor from the centrifuge may be returned to evaporator 1; and the crystals removed for drying and packing.  In order that liquor may circulate from chamber 11 to the evaporator, a return pipe 13 from the top of the chamber communicates with one of the heating tubes 4.  The upper end of tube 13 is not normally connected to its correspondng tube 4, but extends very close to it, or telescopes into it, or is telescoped over a downward extension of the tube.
