Filed: 1944-09-29
Abstract: 581,236. Air-break switches. AKT.-GES. BROWN, BOVERI, & CIE. Sept. 29, 1944, No. 18699. Convention date, Sept 4, 1943. [Class 38 (v)] In a multi-break gasblast circuit - breaker with voltage-distributing impedances in parallel with the power - interrupting points, the residual current through the impedances is interrupted by pressure gas at the series voltage isolating contacts which are maintained constantly under the pressure of the gas. The power switching points are in insulators c', c', and the impedances in insulators e', e<2>. Pressure gas is supplied through valve f and insulator b to the two series breaks of the switch d. After the arcs are extinguished, the pressure is maintained by spring-valves k<1>, k<2>, in order to ensure the voltage isolation. The Specification as open to inspection under Sect. 91 states also that the pressure gas may pass to a single-break isolating switch arm through the insulator supporting the fixed contact or through the arm itself, Fig. 1 (Cancelled, not shown) or through a tube carried by the arm Fig. 2 (Cancelled, not shown). In Fig. 4 (Cancelled, not shown), the stroke of the movable contacts of two series isolating breaks is increased. In these forms the contacts are not held open in a compressed-gas atmosphere. This subject-matter does not apper in the Specification as accepted.

Headings B5A and B5B [Also in Division D1] A fibrous thermoplastic material is made by forming a thermoplastic mass containing gas bubbles, bursting the bubbles by heating the mass and stretching the mass. Preferably the material is formed by extruding the bubble-containing thermoplastic mass through a heated die so as to burst the bubbles then stretching the extrudate after it has left the die. The bubbles can be introduced by use of a gaseous, liquid or solid blowing agent, e.g. sodium bicarbonate, azodicarbonamide or dinitropentamethylenetetramine or by injecting a gas under pressure into the thermoplastic mass. The mass can be polystyrene, acrylonitrile-butadiene-styrene copolymers, acrylonitrile-styrene copolymers, poly vinyl chloride, polymethylmethacrylate or polyethylene or a mixture thereof. The mass may also contain a paraffin oil. The extrusion die can be flat or circular, e.g. to produce sheets or tubular articles and heated to at least 180‹ C. to burst the bubbles. The stretch ratio can be 3 : 1 to 6: 1 in the axial and transverse directions in relation to the longitudinal axis of the die. The fibrous sheets formed can be shaped with or without heating. A polystyrene fibrous product has a density of 0À3-0À6 g/cc. and may be 0À3 to 0À8 mm. thick or 2 to 3 mm. thick.
