Abstract: 949,509. Insulators. COMPAGNIE GENERALE D'ELECTRO-CERAMIQUE. Feb. 14, 1961 [Feb. 24, 1960], No. 5432/61. Drawings to Specification. Heading H2C. An insulator has two end caps with a hollowone-piece insulating envelope extending between them, the internal surface of the envelope being formed to provide an internal leakage path longer than the external leakage path such that the internal surface has a flashover voltage in damp atmosphere greater than the flashover voltage of the external surface under dry conditions. The insulators particularly described each have a strong insulating core made, for example, of bonded glass fibre and cemented to the end caps. The desired result is achieved by providing annular fins or one or more helical fins on the inner surface of the envelope. Fins may also be provided on the core to ensure that arcing will occur across the outside of the envelope in preference to across the core leakage path, this result alternatively being achieved by filling the space between the core and envelope with an insulating filler. The filler may be a fluid such as a silicone grease or may be a solid such as a filled or unfilled resin or filled or unfilled sulphur. Because of differences in thermal expansion coefficients of the various materials a solid filler which adheres strongly to the core may pull away slightly from the flat portions between the fins on the inner surface of the envelope, or if instead the filler adheres strongly to the envelope it may pull away from the core in which case it is again desirable to form the core so as to increase its surface leakage path.

Abstract: 797,708. Washing machines. SULZMANN, E. Feb. 25, 1956, No. 5944/56. Class 138 (2). A method of washing textile articles in a contra-flow installation consisting of several washing machines I to VIII connected in series in a ring, each machine in turn being temporarily disconnected from the ring before the commencement of each new washing stage for loading and unloading purposes, is characterized in that some of the rinsing liquid is led by a controllable connection as a reverse flow from the last rinsing machine (I) to the preceding newly loaded first pre-washing machine (VIII) and unites with the main flow coming out of the installation from the second pre-washing machine (VII). In the example shown, in the double drum washing machines are connected to each other through conduits 10 and containers 11 provided with discharge channels e1 leading to a common conduit e2. The channels e1 are adapted to receive removable overflow members b which determine the liquid level in the machines. Each container 11 has a partition provided with a ledge 12 having an aperture are adapted to receive a stopper (not shown), a plug d having a variable outlet d2, or an overflow member a of slightly lower height than the members b. Rinsing water supplied at 13 to the last rinsing machine I is divided between the machines II and VIII by means of a variable outlet plug d inserted in the opening d1 between machines I and II. The invention ensures that pre-washing is carried out in low-temperature liquid of low alkali content thereby facilitating the removal of spots of blood and the like from the textiles. A stopper is preferably inserted between machines I and II to shut off the passage at d1, and the rinsing water feed shifted to the machine II about two minutes before the discharge of machine I, the plug d being shifted to between machines II and III. A part of the rinsing liquid of machine I is then diverted into machine VIII by temporarily removing the lower overflow member a between the machines VIII and I until the desired liquid level in machine I is produced, whereupon acid or starch can be added to the machine I. Specification 672,755 is referred to.
