Abstract: 720,084. Electric resistances; computing ; two-part couplings; collectors. WILENTCHIK, J. Sept. 6, 1950, No. 21969/50. Classes 37 and 38 (1). [Also in Group XXXVII] Each of a plurality of taps can be adjusted along a resistance and locked in position. As shown in Fig. 2, the resistance is a wire coil 25 in a helical groove 28 having undercut portions; the tap consists of a rod 33 sliding within a bushing 38 having a @ge 41 to engage the undercut portions of groove 28 and locked by rotating sleeve 36 (and thus bushing 34) until the spring-loaded rod is sufficiently pressed against resistance 25. The flange 41 is rectangular, Fig. 2a, so that rotation of it either frees it to slide in the undercut groove or locks it against longitudinal movement. Potentiometer arrangements.-In Fig. 1, taps 23 on a potentiometer 20 are led to taps 44 on a further potentiometer so that as contact 46 is rotated, potentials can be obtained as interpolations between the potentials of taps 23. In Fig. 3, the taps 23 are connected to contacts 54 which are connected in turn in pairs, one to ring 91 by wiper 57 and the other to ring 92 by wiper 58; rings 91, 92 are connected to the interpolating potentiometer 43, and shafts 50, 63 are coupled by an intermittent motion device 68, 69 so that shaft 50 rotates continuously, shaft 63 rotates intermittently to step on the wipers to successive pairs of contacts. In Fig. 7, a plurality of potentiometers 20a ... 20f have taps 23 arranged according to different laws; each set of taps 23 is taken to an interpolating potentiometer, the outputs from each of which are taken to taps on a resistance 43a; as shaft 50 rotates the taps on resistance 43a assume potentials dependent on the laws of the potentiometers 20a ... 20f, and rotation of shaft 50a enables an output to be obtained dependent on any one of these laws or on an interpolation between consecutive laws.

Filed: 1961-06-19
Abstract: 968,888. Printing surfaces. ELECTROGRAPHIC CORPORATION. June 19, 1961 [Feb. 14, 1961], No. 22106/61. Heading B6C. An electrotype shell is mounted on a backing plate by an epoxy resin. The liquid resin, e.g. an epichlorohydrin bisphenol condensate type commercially known as a mono-epoxy resin, is deposited against the back face of the shell 14 which is positioned between a pair of spaced dies 10, 12. The resin is then subjected to a uniform pressure, such as air pressure at 15 lbs. per square inch, which causes the resin to flow into the entire cavity 24 between the dies. The resin is allowed to harden under pressure until it is semi-cured, and still tacky but hardened to dimensional stability. Air trapped between the dies is vented through seals 21 which isolate the cavity from the rest of the apparatus when the dies are in operative sealing engagement as illustrated in Fig. 3. The plate with its resinous backing is then removed from the dies and a curved metal backing plate is applied. Preferably, the resinous layer is applied to the shell to a given overthickness with the application pressure of the backing plate effecting the necessary reduction.

Class 140. [Also in Group XXXV] A laminate comprises a plurality of superimposed sheets of fibrous glass material bonded by a thermosetting resin or mixture of resins, the exterior sheets on one or both sides being coated on the free surface with polytetrafluoroethylene or polychlorotrifluoroethylene. The thermosetting resin may be an epoxy resin, a melamine-aldehyde resin, a phenol-aldehyde resin, a polyester resin which may be of the unsaturated type cross-linked with styrene, a silicone resin, or a mixture of two or more of these resins. The fibrous material may be glass cloth, glass paper, glass mat or the like. The surface sheet may be prepared, e.g. by spraying a suspensoid of PTFE on one side only of a sheet of the fibrous material and fusing the PTFE by heating, or by calendering PTFE on to one side of the fibrous material followed by heating. In the examples, sheets of glass cloth are impregnated with thermosetting resins and precured until tack-free. The required number of sheets is then assembled and the facing sheet of glass cloth coated with PTFE or PCTFE placed on top with its PTFE- or PCTFE-coated side uppermost. The assembly is then heated first without and then with applied pressure. The facing sheet may, but need not be impregnated with the thermosetting resin; if it is, the resin layer on the PTFE- coated side may be stripped off after lamination. The laminate may be used to form a liner for a retaining ring on the rotating member of an electrical machine.

Title: Improvements in or relating to the continuous casting of metal
IPC: B22D11/14
Filed: 1957-07-12
Abstract: 822,578. Continuous-casting machines. WIELAND-WERKE A.G. July 12, 1957 [July 18, 1956], No. 22182/57. Class 83 (1). A mould for continuously casting metal comprises a polygonal casting space within a metal jacket 25 lined with independently-adjustable graphite plates 26. Molten metal from a furnace 11, adjusted about a pivot 15 by a fluid-pressure device 16, passes through a T-shaped, electrically-heated spout 22 lined with steatite, into the mould 10. The mould is reciprocated by a motor through linkage 34, having a variable stroke, and is withdrawn by rollers 13, through a water-bath 12 which may also be reciprocated. The bar is cut in sections by a saw 14. The jacket 25 comprises inner copper plates 43, 44, Fig. 3, bolted together, and outer steel plates 48, 49 welded together. The sets of plates are joined together by bolts 53 passing through upper and lower covers 52, 54. Water enters the space between the plates through lower pipes such as 58, and leaves through upper pipes such as 59. The lining plates 65, 66 are of graphite or graphite-coated carbons and are bevelled to fit into dove-tailed recesses at the bottoms of the copper plates. The tops of the lining plates are also bevelled, and are retained by a frame 67. Clearance spaces 69 allow for expansion of the long plates 65. Specific casting speeds and mould sizes and temperatures are given for casting deoxidized copper, the surface of the molten metal being covered by flake graphite. The water tank may be replaced by a spray. It is stated that the construction of mould dispenses with the need for supplying inert gas to prevent oxidation of the graphite, and permits the graphite plates and copper plates to bow together, thus maintaining a heat-transferring contact. Thermocouples may be inserted in holes bored in the graphite lining-plates and moved vertically to measure the maximum lining-temperature. Specification 705,856 is referred to.

Title: Improvements in or relating to metal-metal oxide laminates
Inventor: HESPENHEIDE WILBUR GENE
IPC: C23C26/00
Filed: 1953-08-18
Abstract: A continuous oxygen-containing layer of a first metal is formed, a continuous layer of a second metal is formed on the first metal layer, the first metal having less affinity for oxygen than the second metal, and the composite is heated in a substantially inert atmosphere at a temperature at which the oxygen in the first layer diffuses into the second layer thereby forming an oxide of the second metal at the interface, which oxide acts as a barrier to prevent diffusion alloying of the metals but permits oxygen diffusion to continue so that the second metal becomes substantially wholly converted to oxide.  The first metal, which may contain oxygen by virtue of its method of formation or which may be partially oxidized, may be Fe, Ni or Co or an alloy thereof, and the second metal may be Al, Ti, Ca, Mg, V, Cr, Zn, Sn, Ba, Mn, Si, Sr, W or Zr.  Several layers of first and second metals may be employed and the laminate may be subjected to a high temperature anneal in a reducing atmosphere: in the latter case, the second metal should be Al, Ti, Ca, Mg or V.  The initial layers may be formed electrolytically, by metal spraying, vapour deposition or sputtering, or pack rolling may be used.  In examples (1) an aluminium ring is coated electrolytically with iron, using a ferrous chloride-sodium p chloride bath, the iron is oxidized by immersion in a solution of caustic soda, nitrates and nitrites, and tin then deposited electrolytically using a bath containing sodium stannate, caustic soda, sodium acetate and hydrogen peroxide; several layers of each of the metals are formed, the aluminium is dissolved away in caustic soda and the laminate heated in argon at 800 DEG F, (2) layers of iron and tin are plated on copper foil and heated in argon at 1200 DEG F., (3) layers of iron and chromium are plated on copper foil and heated at 1500 DEG F. in argon; the chromium layers being formed electrolytically using a chromic oxide-sulphuric acid bath.
