Patent GB-904177-A (GB)
Title: Improvements in or relating to the production of phenolic resin moulding compositions
IPC: C08J3/20
Filed: 1960-11-18
Abstract: Moulding compositions are continuously produced by continuously preparing a resole or novolak, and mixing same with fillers and other desired additions in a heated mixer, then delivering the blended product to a conventional warmed rolling mill.  During the mixing stage, the heating serves to advance the condensation of the resin to the B stage.  The resole or novolak are prepared from phenol, m-cresol or 1,3,5-xylenol and formaldehyde in molar ratio 1:0,8-1:1,2, e.g. by passing over a heated ion-exchange resin or basic catalyst (MgO, CaO), to yield phenol-alcohols, followed by heating in a thin-film evaporator, preferably under vacuum, to give the A-stage resin, which is then mixed with the fillers &c. in a heated screen mixer, or in two stages ((a) 60 DEG -80 DEG C., (b) 80 DEG -110 DEG C.) in two mixers.  Finally, the composition is passed on to a conventional rolling mill, grinding apparatus and bagging plant.

Title: Method of guiding weft yarn and a comb for carrying out the method
IPC: D03D47/30
Filed: 1976-09-24
Abstract: The weft thread (14), inserted into a weft-inserting lamellar comb (1) by means of a primary carrier-medium stream flowing out of a nozzle (13), passes through the orifices (8) of the lamellae forming the comb (1). Some (5) of these lamellae are designed as active lamellae, that is to say they have additional blowing segments (10) which generate a secondary stream. This assists the carrying effect of the primary stream. The axes (15) of these additional blowing segments are arranged in such a way that the weft thread (14) is deflected away from the common axis (12) of the orifices (8) into a region which is as far away as possible from the threading-out gaps adjacent to the upper edge of the orifices. <IMAGE>

Abstract: 1,193,840. Photo-electric measurement of particle size. NATIONAL RESEARCH DEVELOPMENT CORP. Aug.30, 1968 [Sept. 20, 1967], No. 42875/67. Addition to 1, 127, 342. Heading G1A. The invention of the parent Specification is modified in that instead of measuring the intensities of two beams of different energies or energy bands, which have been transmitted by the fluid under test, fluorescent radiation from the fluid is investigated. Thus, in the arrangement of Fig. 2, X-rays from two sources S 1 , S 2  of different energies irradiate the flowing fluid. The energy of one beam is chosen to efficiently excite fluorescence in the substance of which the particles under investigation are composed, and the energy of the other beam to excite fluorescence with low efficiency. After detection of the fluorescent radiation by detectors D1, D2, detector D1 being protected by a filter F 1  from backscattered electrons, the signals produced are passed through amplifiers and pulse height selectors, and scalers, to a timer T 12  for the comparison of the intensities, and on reference to a calibration curve the mean particle size can be obtained. Instead of scintillation counters as in the parent, xenon proportional counters are used as detectors. A particular example mentioned of the use of the method is in determining haematite particles. 3H/Zr and 109 Cd sources which, respectively, efficiently and inefficiently excite fluorescence in the iron, are used. Modifications of the source arrangements that can be used are as in the parent.
