Title: Improvements in or relating to method of making an artificial thermosetting resin and the improved resin resulting therefrom
IPC: C08G16/02
Filed: 1946-07-03
Abstract: Alkali-resistant synthetic resins are prepared by heating a fusible, soluble alkali-catalyzed phenol-aldehyde condensation product with furfuryl alcohol or partially resinified furfuryl alcohol.  The phenol-aldehyde condensate may be in the A or B stage, prepared by reacting phenol, cresol, xylenol or resorcinol or a mixture of mononuclear phenols, but preferably phenol, with an aliphatic aldehyde such as acetaldehyde, propionaldehyde, butyraldehyde or crotonaldehyde, but preferably formaldehyde, with an alkaline catalyst such as hexamethylene tetramine or sodium hydroxide.  The furfuryl alcohol may be partially resinified by heat alone or by the acid of a catalyst such as phosphoric acid, sulphuric acid, oxalic acid, p-toluene sulphonic acid, calcium chloride, ferric chloride, iodine or boron trifluoride.  In the examples resins are prepared by heating: (1) spirit-soluble, ammonia-catalyzed liquid phenol-form-aldehyde resin, furfuryl alcohol and hexamethylene tetramine; (2) water-soluble, sodium hydroxide - catalyzed, phenol - formaldehyde resin, furfuryl alcohol and hexamethylene tetramine; (3) furfuryl alcohol or partially resinified furfuryl alcohol is reacted with sodium hydroxide catalyzed phenol - formaldehyde resins.  The products form good varnishes and may be used for laminating paper. Specification 587,350 is referred to.

Title: Video scrambling system
IPC: H04N7/167
Filed: 1975-05-12
Abstract: 1500779 Secret television systems HUGHES AIRCRAFT CO 12 May 1975 [1 July 1974] 19904/75 Heading H4L In a scrambled television system the video is balance modulated at 6 on to a frequency modulated carrier from 2, so as to provide a suppressed carrier signal, part of the unmodulated carrier being phase shifted at 12 and superimposed on the suppressed carrier signal so as to provide a phase-shifted carrier, modulated in both amplitude and frequency. Audio modulation is frequency modulated on to a further carrier at 18 and, after mixing with the unmodulated carrier from the voltage controlled oscillator 2 and filtering at 22, combined at 16 with the video carrier. The combined signals are conventionally transmitted. A message signal may be used to frequency modulate the voltage controlled oscillator 2 and so provide viewer authorization. At the receiver (Fig. 2) the scrambled modulated signals are fed to a phase detector 32 forming part of a phase-locked loop 32, 44, 40, 38 which thus provides a signal of the same frequency as that from the voltage controlled oscillator 2. The "message" modulation is passed via a 200 Hz low-pass filter 38 to a viewer authorization device 42. The unmodulated carrier from 40 is phase shifted at 46 by the same amount as at 12 and recombined at 34 with the modulated inputs so as to be usable on a conventional TV receiver 50. The use of a double side band system is envisaged.

Abstract: 352,722. Signaturegathering machines. POLLAK, J. E., 20, Holborn, London.-(Brehmer Geb.; Plagwitz, Leipsic, Germany.) July 3, 1930, No. 20244. [Class 100 (i).] Folded sheets or signatures are automatically opened out as they are fed to a signature stitching or gathering machine by passing them between oppositely rotating suction rollers. As shown, the machine comprises a stitching mechanism A and four saddles on a rotating pillar o, the saddles c and b being respectively in signature receiving and stitching positions. The folded signatures S are fed by hand or automatically to the suction rollers e, f, which open out the leaves g, h of the signature, as shown in Fig. 2. Each roller has intercommunicating apertures k, l<1> in its lateral and circumferential faces, and a valve-plate m spring-pressed against the lateral face is in communication with a suction device by means of a pipe n. As the rollers rotate, successive apertures k move below the valve plates m, producing suction at the corresponding apertures l<1>. When they move clear of the valve plates, the suction is relieved, and the signature is dropped on the saddle. The suction period is regulated by varying the size or position of the valve plates. In a modification, only a single row of apertures l<1> is provided, a suction-relieving groove being provided in the lateral face of the roller. For gathering signatures, the saddle moves only when a predetermined number of sheets have been placed on it, and a sheet-folding mechanism may be added.

Abstract: 205,883. Scott, J. P. July 25, 1922. Electrodes.-A perforated electrode plate for electrolysis is welded at its edges to studs or the like projecting from a parallel base-plate which may be comparatively thin. A bipolar electrode is described. The electrode plate may consist of one or more perforated sheets or layers of wire netting. These may be compressed together while the edges are fused to form a solid border 26, Figs. 1 and 4, which may be further shaped. The studs 22 project laterally slightly beyond the edge of the electrode, so that welding may be effected from the side of the studs. During this operation, the base-plate 20 may be clamped between stout frames 27, 28, Fig. 10, and a heavy bar 29 is laid over the upper frame and electrode 21 close to the border, to prevent distortion. In the neighbourhood of the weld, the electrode is held in contact with the bar 29 by a hand-lever. A shield 32 may be placed behind the stud being welded, and the base-plate 20 may be immersed in liquid. Each stud may be provided with a collar 24, Fig. 4, passing through, and a flange 23 engaging the base-plate. After insertion, the stud is secured by spreading the end of the collar by a riveting or caulking tool. Alternate studs are preferably inserted from opposite sides. Additional stiffness may be imparted to the electrode by metal strips 33, Fig. 1, welded to the border and optionally spot-welded at intervals as shown at 34. These strips may abut against supplementary studs, or may be welded thereto. Alternatively, the electrode may be welded directly to the internal studs without the use of strips. Another reinforcing arrangement comprises strips abutting edgewise against the electrode and baseplate and optionally welded at intervals, the ends of the strips being twisted and welded to the border of the electrode. The base-plate may be of conductive metallic or non-metallic material.
