Abstract: 316,006. Dicker, S. G. S., (Rubber Latex Research Corporation). July 23, 1928. Latex, concentrating.-Latex is concentrated in the presence of haemoglobin, and is then dried in an atmosphere of sub-normal humidity. Concentration which may be by centrifuging is conducted at a temperature low enough to avoid coagulation of the haemoglobin. Drying may be effected by spraying the concentrate into air of low relative humidity.

Title: Telephone trunk supervisory circuits
IPC: H04Q3/42
Filed: 1974-05-15
Abstract: 1474769 Automatic exchange systems; pulse oscillators WESTERN ELECTRIC CO Inc 15 May 1974 [17 May 1973] 21433/74 Headings H4K and H3T A trunk supervisory circuit includes a first terminal and a second terminal between which are connected a path for direct current in one direction and a path for direct current in the other direction, a portion of those paths being common and including a current control circuit biased to prevent a high impedance to alternating signalling to a predetermined magnitude. The Figure shows the common control 590 of a local office and a trunk T1, R1 to a distant office. To seize the trunk the common control removes an enabling potential on a transistor 580 which normally prevents operation of an oscillator 551. Transistor 553 conducts causing transistor 555 to conduct inhibiting transistor 552. After a time determined by inductor 558 and resistors 560, 561 the base emitter voltage of transistor 553 drops below its threshold and transistor 553 turns off turning off transistor 555 allowing transistor 552 to conduct. The oscillator returns to its first state in similar fashion producing non-overlapping constant current pulses alternately via resistors 564 and 565. These pulses alternately charge capacitors 518 and 519 which together constitute a power supply for a constant current transistor 510 and a bias voltage therefor. Transistor 510 turns on effectively looping the line T1, R1 and depending on the polarity of the line potential applied at the distant office direct current flows through one path (through winding 531 and the emitter collector paths of transistor 510 and thyristors 506 and 509) or the other (through winding 532 and the emitter collector paths of transistor 510 and thyristors 507 and 508) of a bridge 500. depending on the polarity one or other of the output transistors 562 and 563 meets a heavy load on the transformer 530 and as its emitter receives constant current pulses produces a high base current turning on a corresponding transistor 568 or 569 which in turn signals the polarity to the common control. The trunk may be used for impulsing being seized for each impulse. When the wanted subscriber goes off-hook and returns to hook during the call the distant office effects a polarity reversal to signal this fact to the local exchange.

Abstract: 1,197,541. Multiplex radio signalling. XEROX CORP. 8 May, 1968 [12 May, 1967] No. 21736/68. Heading H4L. Facsimile signals are time division multiplexed with a television signal during the vertical blanking period. As described, the facsimile signals are included during the intervals between the horizontal synchronizing pulses which follow the second group of equalizing pulses in the vertical blanking period of a negative modulation television signal. A generator 24, Fig. 2, provides sync. signals for a conventional TV system including a camera 23 and a facsimile scanner unit 25 is controlled by the generator 24 via a timing device 27 and provides signals from a document 26 which are converted at 28 into one or zero bits indicating black or white respectively. The output of coder 28 is supplied via an AND gate 29 to a buffer 30 where it is fed in at a relatively slow rate and read out at a high rate under the control of clock 31 via AND gate 40 and OR gate 60. The output of clock 31 is counted down at 34 to control the quantizer clock 36. The clock 36 via a control circuit 37 enables the AND gate 29. The AND gate 40 is enabled by a signal from a start burst detector 102 at the end of the second equalizing pulse group of the vertical blanking signal. The output of the buffer 30 is supplied via a video gate 42 to a transmission line 22. The receiver, Fig. 2A (not shown), operates in a converse manner and may be in the form of an adapter arranged to be plugged into a TV receiver at a point where the synchronizing signal is available.

Abstract: Phenyl phenols containing less than 3 per cent by weight of alpha-naphthol are stabilized against colour formation by treatment with not more than 5 per cent by weight of citric, tartaric, or phosphoric acids or mixtures thereof.  The treatment may be effected by stirring the solid acid or an aqueous solution thereof with the molten phenol, by stirring crushed solid phenol with an aqueous solution of the acid, or by dissolving the phenol and acid in alcohol and precipitating the phenol by addition of water; the phenol is then separated, e.g. by filtration or decantation, and may be subjected to washing or recrystallization. In an example, orthophenyl phenol is treated with citric acid.
