Patent GB-587160-A (GB)
Title: Improvements in or relating to synthetic resins for use in producing electrical insulation
IPC: H01B3/42
Filed: 1944-04-17
Abstract: A material for use as electrical insulation or as a binder for mica flakes or other dielectric sheet or flake material to make electrical insulation is the resinous reaction product of 1 mol. of pentaerythritol, 1.5 mols. of maleic acid or anhydride (plus or minus 10 per cent) and 0.5 mols. of phthalic acid or anhydride (plus or minus 10 per cent).  The materials are charged into a vessel equipped with reflux condenser and heated to 130 DEG  C. in an atmosphere of carbon-dioxide or nitrogen.  The temperature then rises rapidly due to reaction.  Reaction is continued until an acid number of 220-280 is reached.  The product should have a ball and tapered ring softening point of 50-80 DEG  C.  It is thermoplastic, but sets if treated at temperatures of 150-200 DEG  C. It is soluble in acetone, ethanol, acetone-benzene, or ethanol-benzene.  A solution containing 2-25 per cent by weight of resin is suitable for application to mica flakes.  Flat sheets suitable for punching or cutting commutator or similar simply shaped insulation may be made with the aid of the resin (see Group V).  Mica flakes mixed with resinous binder may also be moulded to specific shapes such as a V-ring for a dynamo-electric machine (see Group XXXV).  When moulding the pentaerthyritol-maleate-phthalate resin, fillers such as silica, asbestos fibres or porcelain particles may be incorporated therewith. Synthetic mica or films of treated bentonite may also be cemented with the resinous material.

Abstract: 493,747. Washing-machines. GOHL, F. March 14, 1938, No. 7842. [Class 138 (ii)] Water is withdrawn from the washing compartment 1 of a washing-machine through a perforated partition 5 into a suction chamber 6 from which it is drawn by a pump 9 and passed through a chamber containing steam-heating pipes 14 and then by a pipe 16 containing a valve 15 to nozzles 2. The nozzles are directed downwardly and cause the goods to travel in a triangular path about a horizontal axis. Air passages 3 of differing diameters may be rotated into or removed wholly from proximity to the jets, whereby more or less air may be drawn in by the water jets. These passages may also be used for the return to the washing compartment of soapy liquid that has had the foam removed. Foam is removed in the chamber 17 containing an inverted conical member 51 loosely resting on top of the pipe 55 and provided with external perforated ribs. The soapy liquid passes to injectors 20 operated by water from the pump controlled by valves, or to the air passages 3 through a pipe, not shown.

Abstract: 891,463. Spraying fusible materials. PLASMADYNE CORPORATION. March 12, 1958 [March 29, 1957], No. 7983/58. Class 69 (3). [Also in Groups XI and XL (a)] An arc torch for producing a stream 138 of plasma consisting of neutral gas, ions and electrons comprises two flat cylindrical electrodes 89, 92, and a neutral gas continuously passed through inlets 72, 136 into the space between them passes through a nozzle 137 formed in one electrode, thereby constricting an arc extending between the electrodes adjacent the nozzle. The gas, preferably one preventing oxidation, e.g. argon or helium, is introduced through one or more tangential inlets 136 in a cylindrical wall of the space separating the electrodes. The gas enters adjacent the upper electrode 92 with the nozzle 137 and forms a vortex constricting the arc 138, which is carried by the gas through the nozzle, e.g. at 15,000 K. The rear electrode 89 has arc-receiving parts lying closer to the axis of the opening than any part of electrode 92. The gas pressure in the cylindrical chamber between the electrodes is at least 1.6 times the ambient pressure; and the diameter of the chamber of which the electrodes from the top and bottom walls is at least twice the diameter of the opening of the nozzle. The distance between the electrodes is equal to or not more than four times the diameter of the nozzle. The electrodes are connected as shown with insulation 108, 109 between them, and are supplied with D.C. with negative voltage to the nozzle electrode 91. The current is supplied to a point on the circumference of each flat cylindrical electrode, so that current flow through the metal electrodes is radially inward. The electrodes are cooled by fluid passing through cavities 96, 114 in them from an inlet 52 to an outlet 68, the cavities being connected in series by a long insulating pipe 131. The cross-sectional area of the gas inlets 136 is less than that of the opening of the nozzle. The gas inlet passages are at the potential of the electrode and may comprise a tangential slit. A conductive refractory 107 is provided at the end of the arc at least on the electrode 89. An inlet opening 99 in the electrode 89 allows introduction of auxiliary substances into the arc, e.g. gas or a metal powder or ceramic powder for spraying. Auxiliary substances may be added, the gas entering at 136 and may be introduced into the arc adjacent the outer surface of a cap 92 holding in place a tubular metal 121 forming the nozzle.
