Title: Cold-hardening compositions containing phenol-formaldehyde condensation products, and a process for making such compositions
IPC: C08G8/00
Filed: 1950-10-11
Abstract: Compositions capable of hardening rapidly in the cold comprise furfural, a liquid condensation product obtained by condensing formaldehyde with at least one mononuclear monohydric phenol in an alkaline medium, at least one hardening agent therefor and at least one filler.  Hardeners specified are acid or neutral persulphates, titanium sulphate, neutral metal dioxides such as lead and manganese dioxides, aromatic sulphochlorides such as para-toluene-and b -naphthalene-sulphochlorides, aralkyl chlorides and sulphates such as dichloromethylmeta-xylol and dibenzyl sulphate, and naphthalene disulphonic acids, such as 1:5-naphthalene disulphonic acid.  Fillers specified are quartz powder, barium sulphate, natural or artificial graphite, silicon and silicon compounds, such as silicon carbide. Besides furfurol other substances capable of increasing the chemical resistance of the resin mixture may be added, e.g. aliphatic esters of inorganic acids such as diethyl,-dipropyl-sulphates, triethylphosphate, dichloropropanol, epichlorhydrin, dichlorhydrin and ethylenechlorhydrin, chlorinated aliphatic alcohols and aldehydes such as ortho-chlorobenzaldehyde, b -dichloro-propionaldehyde hydrate and chloralhydrate; these substances may be added alone or in admixture.  The mixture may be made by mixing the hardener(s) with the inert filler(s) and mixing the resulting powder with the liquid condensate and furfurol.  If desired, the mixture of furfurol and the liquid condensate may be heated before use, by refluxing for 1-2 hours.  The composition may be made up into two separately packed parts to be mixed prior to use, one part consisting of a powder containing the filler and hardener and the other part consisting of a liquid composed of the condensate and furfurol.  The liquid condensate is preferably made from formaldehyde and phenol or isomeric cresols or xylenols or any mixture thereof, in the molecular proportions of 1:1 to 1.8:1, by introducing the phenol into caustic soda solution at 60-70 DEG  C., cooling to 35-40 DEG  C. and adding formalin thereto.  After maintaining the mixture at this temperature for 2-3 days, it is neutralised with hydrochloric acid while cooling with ice, the resin layer being separated, washed, and its pH adjusted to 7-8 by addition of caustic soda.  Examples are given.

Abstract: 810,482. Fluid-pressure servomotor-control systems. LINEN INDUSTRY RESEARCH ASSOCIATION. Sept. 5, 1956 [Sept. 7, 1955], No. 25593/55. Class 135. [Also in Groups IX and XIX] A servomotor system for controlling the tension of a thread 1 as it is passed to or delivered from a textile machine, comprises two stationary bars 2, 2 over which the thread 1 passes, and a light feeler arm 3 between the bars 2, 2, tending to hold the thread 1 against the bars, the feeler arm 3 being secured to an arm 4 freely pivoted at one end 5 and carrying a vane 6 at the other end, the vane 6 being movable between two opposed orifices 7, 8, one of which (7) is connected to a supply of compressed air and the other (8) to a bellows 9 and to a pressure responsive control, measuring or recording device 12; the arm 4 being attached to the bellows 9. If the tension in the thread 1 increases, the feeler arm 3 is deflected such that it causes the vane 6 to move away from a position between the opposed nozzles 7 and 8 and air from the nozzle 7 then passes into the nozzle 8 to create a pressure in the bellows 9. The resulting displacement of the bellows 9 tends to counteract the force exerted by the thread 1 on the feeler arm 3 and when a state of equilibrium has been reached the resulting pressure is indicated on a pressure gauge 12. The pressure in the bellows 9 or, in the gauge 12, is used to operate any known type of pneumatic control device to vary the operation of any part of the textile machine in accordance with the tension in the thread. In a modified construction a light spring is inserted between the arm 3 and the bellows 9, and an additional spring acts on the bellows 9 to restrict its movement. Specification 737,629 is referred to.

[Also in Group XX] A sextant or other angle measuring instrument is provided with a control lever 8, Fig. 2, movable by the operator in one direction and spring returned in the other, each successive movement of which rotates a shaft 62 one eighth of a revolution by means of a pawl 60 and ratchet 61, the shaft 62 carrying cams 75 ... 78 operating spring arms 80 ... 84 which control electric circuits for the integrator motor, bubble lighting and dial illumination. On the first movement of the lever 8 the illuminating circuits are switched on by means of the spring arms 82, 83, Fig. 8. The second movement starts the motor 28 of the integrating mechanism by means of blades 80. If the integrating mechanism runs to the full extent of its travel (corresponding to about 290 degrees revolution of the pinion 22, Fig. 2) before thelever is again operated it is automatically stopped by blades 91 operated by a cam 89 on the pinion shaft 40. After such an automatic stop the third movement of lever 8 merely prepares the switches for the fourth sequence of operations, if however the measuring arm has not reached its full extent when the third movement of the lever is made that movement switches off the integrator motor 28. On the fourth movement the motor drive is reversed and returns the integrating mechanism at a higher speed to its starting position where the motor is stopped by blades 90 operated by cam 88 on the shaft 40. The reversal of the motor drive and the engagement of higher return gears is effected by means of a clutch lever 69 having at one end a pin engaging a groove 68 in a cam block 67 on the shaft 62 and at the other end a pin engaged in a groove 70 in a block 71 integral with a pinion and clutch in the integrator motor gearing.
