Title: Process and apparatus for the continuous or semi-continuous heat treatment of material in web form
IPC: D06B15/12
Filed: 1964-06-12
Abstract: 1,068,374. Textile treating apparatus; finish ing fabrics. C. A. MEIER-WINDHORST. June 12, 1964 [Oct. 14, 1963], No. 24418/64. Headings D1L and D1S. A process for the continuous heat treatment of webs of textile material in which the web, impregnated or soaked in a treating agent, is preheated, firstly, by condensation heating in a vapour-air mixture, or in pure water vapour, approximately to the saturation temperature associated with the particular partial vapour pressure of the vapour-air mixture, or pure water vapour, and, secondly, by non-condensation heating which follows immediately after or is partially superimposed upon the condensation heating. In the embodiment shown in Fig. 1, the web 20 passes into a chamber 14 which isolates the heating zone 13 from the outer air, a zone 15 of pure condensation heating, and a zone 17 of pure non-condensation heating, e.g. radiation heating by heaters 18, contact heating or high frequency heating. A zone 16 is located between the zones 15, 17 and combines condensation heating and non-condensation heating. The web 20 passes through a slit in a partition 19 to a pad-roll chamber 10 into the lower part of which a vapour-air mixture or pure water vapour is introduced to be conveyed through the plant in counter flow to the direction of travel of the web 20. Steam is supplied from a pipe 26 and may be brought to the desired working pressure by a manually adjustable pressure reducer 25 and is introduced into the chamber 10 by an injector 24 which produces a vapour-air mixture, air supply being regulated by an adjustable butterfly throttle 23. The volume ratio of vapour to air is determined by the standard wet-bulb thermometer temperature. The vapour-air mixture may be supplied to give a somewhat lower web-bulb temperature, the desired temperature then being automatically regulated by an additional quantity of pure water vapour supplied through a valve 22 controlled from a measuring device 27. A baffle plate 21 protects the web from the direct admission of the vapour-air mixture. In a second embodiment, Fig. 2, after passing through condensation and non-condensation heating zones 15, 17, respectively, the web 20 passes into a J-box 12 into which a vapour-air mixture or pure water vapour is introduced. To seal the J-box 12 from the outer air a water trap 28 is provided. In a further embodiment, Fig. 3, the web 20 is treated in a chamber 11 after passing through the zones 15, 17.

Title: Improvements in and relating to electrical oil switch fuses
IPC: H01H85/40
Filed: 1931-09-01
Abstract: 382,701. Oil switch-fuses. NORTON, R. T., 10, Anderson Street, Sloane Square, London. Sept. 1, 1931, No. 24527.. [Class 38 (v).] Covers; switch mechanism interlocking with lids.-In an oil switch-fuse having an oil container with inner and outer covers, the fuse acts as a bridging member and is provided with means for operating it to the open and closed positions when both covers are closed, and to project it through an opening or slot in the inner cover for inspection or renewal when the outer cover is opened. The fuse 44 of each phase is mounted in clips on the top of contacts 42, which co-operate with main and arcing contacts 24, 25, and are assembled on insulating bridges 41 spaced apart on rods 45 which are secured to endplates 46 to form a frame. The frame is moved as a whole by means of a bell crank 40 at each end, secured to a shaft 39 and connected by a link 37 to a pin 48 on each endplate 46, the pin 48 being forked and carrying a roller which engages a guide-rod 37 fastened in the cover 1. Counterclockwise rotation of the shaft 39 raises the bridges to the dotted position in which the ends of the bell cranks project through slots in the inner cover and engage buffers 36 on the outer cover 32. After removing the nuts 35, which have springs to enable products of arcing to be vented, the outer cover 32 may be opened and the shaft 39 further rotated to the chain line position in which the fuses project through slots 27 in the inner cover for renewal or inspection. The latter movement may be automatically effected by springs on removal of the cover 32, and the bridges may carry projections completely filling up the slots in the inspection position. In the modification shown in Figs. 4 and 5, the parts 35 are dispensed with and instead the shaft 39 and cover 32 carry cams 56, 60, respectively, which, when the switch is closed, Fig. 4, prevent opening of the cover 32 and when the cover 32 is open, Fig. 5, prevent rotation of the shaft 39 to close the switch. The lid 32 is further provided with locks 63 on a shaft 64 having a slotted arm 66 co-operating with pins 68 on a sleeve that is held between collars 70 on a rotatable shaft 71. Rotation of the latter to free the cover 32 in the closed position of the switch, Fig. 4, is prevented by the cam 56 and the shaft 71 prevents closing the switch when the cover 32 is freed, Fig. 5. A compound filled chamber 55 enclosing the bushings may be provided with a reversible cable box for connection of the switch-fuse with a cable, and a similar chamber on the other side may house a connection between the switch and a power transformer. The operation may be by fixed or loose handle and the tank 2 may be arranged for lowering, with the necessary interlocks with the operating mechanism. The operating mechanism shown may be replaced by one of the character disclosed in Specification 368,854.

Abstract: 616,031. Gas-blast switches. ETABLISSEMENTS MERLIN & GERIN. Aug. 21, 1946, No. 24924. Convention date, March 8, 1945. [Class 38 (v)] A voltage-limiting impedance 8, which may be a resistance, capacitance, &c., is connected in shunt to the main-contacts 1, 2 of a gasblast circuit-breaker a short time before the main-arc is extinguished, and disconnected again a short time after the extinguishment. This is effected in Fig. 1, when ionized gas conducted from inside the fixed nozzle 1, via a conduit 13, is discharged between auxiliary electrodes 9, 10 through an orifice 12 in an insulating-casing 11. The auxiliary arc between electrodes 9, 10 will be sustained for a short time after extinguishment of the main arc, until the ionized gas trapped in the conduit 13 by the insulating gas passing through the nozzle 1, has all been discharged through the orifice 12. In Fig. 2 (not shown), the casing 11 itself opens into the blast-chamber to provide a stream of insulating gas between the electrodes 9, 10, the ionized gas in conduit 13 being discharged into the centre of the insulating stream. In Fig. 3, the conduit 13 opens into an exhaust-gas collector 20, which may have an inlet-orifice 21 larger than an outlet-orifice 22. The end of the conduit 13 may alternatively be sealed and project into the upper end of an exhaust-gas collector, ionized gas entering the conduit 13 through a number of holes so as to exclude arc-products, (Fig. 4, not shown). In Fig. 5 (not shown), insulating- gas taken from the blast-chamber is ionized by the main arc as it passes through a permeable tube (e.g. quartz) arranged on the exhaust side of the fixed nozzle. In Fig. 6 (not shown), the conduit 13 opens into an axial hole bored into a solid fixed contact, arc-products being trapped in the blind end of the hole.
