Title: Raschel machine
IPC: D04B21/20
Filed: 1966-08-17
Abstract: A simulated fall plate fabric is knitted on a Raschel machine having needles with short latches to enable the fall plate yarns to be fed beneath the latches at the same time as the other yarns are fed into the needle hooks.  To prevent premature closing of the latches the machine has a stitch comb mounted on the latch side of the needles as described in Specification 750891. Openwork fabrics may be produced suitable for an insert in paper or plastic foils.  A somewhat elastic yarn of synthetic fibres may be used as the fall plate yarns. Alternatively a two bar Raschel machine may be used on which the fall plate yarns of the elastic synthetic fibre may be fed to needles of one bar whilst the other bar produces a ground fabric from synthetic monofilament yarns, the fall plate fabric being attached at intervals to the ground fabric by intertwining.  The low softening point of the monofilament yarns enables the fabric to be deformed and stabilizes the fabric of the elastic spun yarns when used for brassieres and bathing costumes.

Skewing of the elevator 22 is prevented by two pairs of flanged rollers 27 mounted on the structure 17. The scoop 28 is formed with a plurality of apertures 28a, e.g. slots, for filter medium lifted with the sludge to fall back on to the bed 11. Sludge lifted by the elevator 22 is directed on to the conveyer 30 by a shoot 33 formed integrally with a part-cylindrical guide plate 34 secured to the structure 17. Electricity may be supplied for the various movements of the apparatus through a cable drum on the gantry or an alternator driven by a prime mover may be disposed on the gantry.

Title: Arrangements for introducing thermocouples and like devices into pressurised reaction chambers

Abstract: 943,826. Thermometers. HEINRICH KOPPERS G.m.b.H. Oct. 5, 1962 [Oct. 6,1961], No. 37703/62. Heading G1D. When introducing thermocouples or like devices into a pressurised reaction chamber 4, the escape of hot, and possibly poisonous, reaction gas is avoided by providing a flap 14 which normally seals the inner end of a passage 7 and may be removed laterally to open the passage. The thermocouple is thus introduced until it forms a gas seal with packing 10, whereupon a nut 19 is unscrewed on its shaft 12 to allow a plug 18 to be released. The shaft 12 is then pushed into free space 24, to free flap 14 from its gasket 15, and rotated so that flap 14 is moved laterally away from passage 7 and the thermocouple may be inserted further into the chamber 4. The packing 10, which is initially somewhat loosened, is pressed by gland 9 to give complete gas-tightness whilst measurements are made. A stop 25 ensures that on rotating shaft 12 back again, the flap 14 is centred on gasket 15.
