Title: Apparatus for trimming grinding wheels
IPC: B24B53/08
Filed: 1965-02-16
Abstract: 1,096,223. Trueing grinding wheels. NATIONAL BROACH & MACHINE CO. Feb. 16, 1965 [April 14, 1964; Aug. 17, 1964], No. 6622/65. Heading B3D. A grinding wheel for use in form grinding a helicoidal surface of a workpiece is trimmed by rotating the wheel on its axis, and moving wheel forming means in contact with the wheel to trace a helicoidal surface thereon substantially identical with the helicoidal surface desired on the workpiece. The grinding wheel W is carried by a slide 18, Fig. 1, vertically adjustable on a column 16 which is adjustable about a vertical axis passing through the centre of the grinding wheel to adjust the plane of the grinding wheel to the helical angle of the workpiece. A workpiece to be ground is mounted on an arbor 24 between a headstock 22 and tailstock 26 on a table 12 reciprocatable on a bed 10, the arbor being rotated during movement of the table by a lead bar 28 which is connected to the arbor and engages a fixed nut 30. When the wheel is to be trimmed, the workpiece is moved from the vicinity of the wheel and replaced by a trimming device 34, Fig. 3, consisting of a base 56, which is mounted on a way 58 on the table 12. A block 62 is mounted on the base and has a pair of ears 64 between which a member 66 is adjustably secured. The member 66 is connected by parallel links 70 to a body 68 slidably receiving a member 76 at one end provided with a trimming tool 82, such as a diamond, and at the other end having a follower 84 which is urged by a spring 80 into engagement with the surface 50 of a template 49 carried by a plate 42 adjustably secured to a carrier 48 mounted on a bracket 32 on the bed 10 of the machine. The surface 50 is a three-dimensional involute or arcuate helicoidal surface substantially identical to that to be formed on the workpiece and, in operation, as the table is traversed to move the trimming mechanism slowly past the grinding wheel and template, the body 68 is oscillated by a handle on one of the pivots 72h or a motor engaged therewith to cause the diamond 82 to traverse a plurality of closely-spaced substantially parallel paths and trace a surface on the grinding wheel substantially identical to that 50 on the template. The template may have a surface several times larger than that to be formed on the grinding wheel and workpiece and the trimming device incorporate a pantograph mechanism. The arrangement prevents an incorrect surface being ground on the workpiece by heel and toe interference of the grinding wheel with the workpiece.

Patent GB-545184-A (GB)
Title: Improved method of heat exchange and apparatus for this purpose
IPC: F25B33/00
Filed: 1940-04-15
Abstract: 545,184. Heating systems; refrigerating. SVENSKA AKTIEBOLAGET GASACCUMULATOR. April 15, 1940, No. 6787. Convention date, April 22, 1939. [Classes 29 and 64 (ii)] In a closed-cycle condensing heat transfer system in which the heat-absorbing or evaporator element 1 is located above the heat-emitting or condenser element 6, the medium circulates between the elements through a reservoir 3 and a single conduit 4, and is raised from the condenser element, after evaporation is completed, by pressure variation in the system and syphoned from the reservoir 3. The element 1 heated by a continuous heater 2 is connected with the vessel 3 surrounded by insulation 8 except at a part 9 where it is exposed to a draught of air controllable by a damper 10. In one phase evaporation proceeds and the heat of condensation is given out to water in a tank 11, and condensate collects in a receiver 5 surrounded by a heat-insulated heat-storing mass 13. Towards the end of the evaporating period vapour bubbles through condensate in the receiver to heat the mass 13, and vapour accumulates above the condensate. After evaporation ceases the pressure in vessels 3 is reduced by the cooling of the wall 9, and the heat-stored in mass 13 vapourizes condensate in the collector 5 and liquid is forced back up tube 4 into vessel 3. As soon as the level rises sufficiently to prime a siphon 7 the vessel 3 empties into the evaporator element 1. The frequency of the alternating periods may be varied by adjustment of the air damper 10. The invention is particularly applicable to the heating of the generator-absorber 19, Fig. 3 of a reversing absorption refrigerating system, the main condensercollector element 20 having a supplementary condenser member 21 with pipes 22, 23 opening above the level of pipe 4. Cooling of the vessel 3 is effected by circulation of vapour through a pipe 16 to a condenser member 14 having an extension 24 provided with a removable insulated cap 25. Condensate returns to vessel 3 by a pipe 15 but does not at first rise above level B. Liquid is returned from the collector 20 until the liquid level reaches pipe 4, after which the remaining liquid evaporates and condenses in the system 20, 22, 23 to effect cooling of the generatorabsorber. Continued condensation in vessels 14, 24 eventually raises the level in vessel 3 to prime the siphon 7 and start a fresh heating period. An expansion vessel 26 kept at the desired maximum temperature of the condenser 20 receives heat transfer medium and thereby stops the heat transfer when this temperature tends to be exceeded. In a further modification the expansion vessel is heat insulated except for a part exposed to the continuous heat source, and the pipe 16 opens into the evaporating element 1 outside the vessel 3.

A recuperator for preheating air, for example for a cupola furnace comprises a series of metal e.g. cast iron tubes 3 of oval or rectangular cross-section having external ribs 4 and internal projections 5, the tubes which convey the air to be heated, being disposed in parallel rows in a chamber 2 through which flows hot flue or other gases. At both ends, each tube has cylindrical extensions 6 which project through respective apertures 8 in opposite walls 1 of the chamber the extensions being sealed in respective stuffing boxes 15 secured to the end walls 13 of inlet or outlet air casings 14. The casings are supported from the external frame 22 of the recuperator by resilient links 23. The tubes 3 are supported at their ends on flat iron bars 9 having recesses 10 in which the tube extensions 6 rest freely, thus allowing for expansion and contraction movements of the tubes. The bars 9 are secured to the frame 22 and are cooled by the ambient air.

Title: Improved method of and means for preventing the formation of and for detaching incrustations in containers, more particularly in steam boilers and the like
IPC: F22B37/48
Filed: 1932-03-08
Abstract: 397,941. Preventing and removing incrustation. SCHIRMER, A., 45, Sch÷nbrunner-Schloss-Strasse, Vienna. March 8, 1932, No. 6919. Convention date, March 9, 1931. [Class 123 (i).] In preventing and removing incrustation by electrical means in which a boiler wall acting as cathode, and an inner electrode immersed in the water are alternately polarized and depolarized, voltages, preferably equal to the polarization voltage for hydrogen with reference to the material of the boiler (about 0À1 volts) and at most equal to the decomposition voltage (1À6 volts) are employed for polarizing. During polarization the layer of hydrogen formed on the wall of the container is prevented from escaping and a uniform electro-chemical action is thereby obtained during depolarization. If the voltage of the current source be higher than that required, the boiler K and inner electrode A are arranged in parallel with a constant resistance W and by means of a variable resistance W<1> the voltage may be reduced. Between the conductors L1 and L2 is a connection V with a switch S operated by clockwork. At the beginning, the switch interrupts the connection between the leads, and a layer of hydrogen forms on the boiler wall. On reversal of the switch, a polarization current is transmitted through the connection V, the boiler wall, and the water, to the electrode A. The feed-pipe may act as the inner electrode.

Abstract: 845,981. Electrode furnaces for molten glass. ELEMELT Ltd. March 12 1956 [March 11, 1955], No. 7154/55. Class 39(3). Glass is melted or refined by passing current substantially horizontally through a body of the glass between electrodes spaced horizontally over an area extending substantially to the lateral and lower boundaries of the body of glass supported in a furnace having side and bottom walls which do not react with the glass and have a lower conductivity than the layers of glass adjacent thereto when the temperature of the inner part of the glass is maintained by the current at 1500‹C or higher e.g. at 1640‹C. Thus the bottom and side walls may be of sillimanite or a fusion cast refractory e.g. zirconia, alumina, silica or a mixture thereof, and the ratio of electrical conductivity of the material chosen to that of the glass should be not more than 1 : 1À1. The electrodes may be molybdenum plates supported on fluid-cooled stems as in Specification 756,382 and are supported within 6 inches and preferably within 2 inches of the side and bottom walls. The electrical conductivity of the glass may be increased by adding thereto a salt or compound of an alkali metal which will dissociate electrolytically and of such composition and in such quantity e.g. 0À01-0À25% by weight as not to impair the useful properties of the glass. Thus to borosilicate glass may be added a salt of sodium, potassium or lithium, e.g. sodium chloride, petalite, or lithium carbonate. Specifications 835,201 and 845,982 are referred to.
