The working life of the wire of a Fourdrinier paper making machine is extended by applying to the return run of the wire while in operation a dilute aqueous solution of a combination of chemicals comprising: (a) from 5%-98% by weight of a water soluble, extreme pressure lubricant comprising a nitrogen-containing heterocyclic compound characterised by a ring nitrogen bonded to a ring carbon to which is attached a sulphydryl group and (b) from 2%-95% by weight of a water miscible dispersing agent from the group consisting of water miscible nonionic and anionic dispersing agents. The solution which is preferably applied by sprays 17 to the return run of the wire immediately prior to the breast roll is supplied in sufficient quantity to provide at least 0.005 pounds of the combined chemicals per ton, dry weight, of paper produced by the machine, and serves both to lubricate the wire thereby reducing abrasive wear and also to prevent blockage of the open areas of the wire mesh by improving drainage characteristics. The composition of the mixture of chemicals may be modified, particularly where friction at the suction boxes is high, by the inclusion of from 0.001 to 0.5% by weight of a water dispersible organic silicon-containing compound from the group consisting of organo-silicon oxide condensation products and organo functional silanes.

Abstract: 844,850. Circuits employing bi-stable magnetic elements. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 12, 1956 [Dec. 19, 1955], No.36294/55. Class 40(9). [Also in Group XIX] A pair of magnetic cores CA, CB with rectangular hysteresis loppe, Figs. 2a, 2b and 3, each have a coil connected to the base b and emitter e of a transistor TA, TB, while a coil on the other core is coupled to the collector c. When the remanent condition of a core is changed from state 1 to state 0 by an input pulse, the associated transistor becomes conductive and applies a state 1 driving pulse to the other core. A voltage-controlled counter or trigger pair is shown in Fig. 2a in which the cores are initially in opposite remanent states 0 and 1 and are triggered alternately by input pulses applied over resistors RS. A modified circuit, Fig. 2b, arranged for current control has additional O-driving coils in the input circuit. An alternative arrangement is shown in Fig. 3 in which both cores are initially in state O, and pulses are applied alternately to input and reset terminals. A complete operating cycle requires two reset and two input pulses and the circuit responds as follows: (a) The first reset pulse is without effect. (b) The first input pulse drives core CB to state 1. (c) The second reset pulse restores CB to state O so that transistor TB conducts and drives core CA to state 1. (d) The second input pulse restores CA to state 0 and attempts to drive CB to state 1. The latter action is inhibited, however, by an 0-driving pulse produced by transistor TA. A condenser C may be incorporated as shown to reduce spurious outputs, and the input pulses and the transistor TA outputs may be applied to a common coil on core CB. A multistage counter may be formed by several Fig. 3 circuits connected in cascade, Fig. 7 (not shown).

Title: Improvements in or relating to radio and the like signalling systems
IPC: H04L5/12
Filed: 1928-12-10
Abstract: 302,181. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Alexanderson, E. F. W.). Dec. 9, 1927, [Convention date]. Multiplex signalling; keying systems and apparatus; secret signalling.-Relates to a method of signalling by using a phase-reversal of the transmitted energy to represent a dash as distinct from a dot, thus allowing a reduction of the time necessary say for transmitting the letter F in Morse code from nine time units, including the spacing intervals, as shown in Fig. 1 to four time units as shown in Fig. 4. According to the invention, in order to prevent loss in overcoming persistent aerial oscillations on phase - reversal, keying is effected by momentarily interrupting the energy supply to the aerial and simultaneously detuning the aerial for the period necessary to produce 180‹ change in the current flow. The method of doing this is illustrated in Fig. 5. A constant-frequency generator 8, controlled by a piezo-crystal 10, is connected in direct phase to the aerial through conductors 12, 14 and relay-operated switches 22, 24, and in reversed phase by conductors 16, 18 and switches 26, 28. The key 30 when in contact with segment 34 closes the switches 22 and 24, and when in contact with segment 36 closes the switches 26, 28. In the mid-position, the switches are all closed so that the generator 8 is short-circuited. As it moves through the mid-position the key 30 brushes a third segment 38, which operates a relay 50 to close a switch 44 for the proper time-interval to ensure a phase-reversal of the aerial currents, say for the two-thousandth part of a second, prior to the closing of the reversedfeed switches 26, 28. This closes the directcurrent or saturating circuit of a magnetic amplifier 42 to detune the aerial for the purpose of preventing clash between the persisting and phase-reversed aerial oscillations. Fig. 6 shows a similar arrangement for duplex transmission. The high-frequency alternator 80 is so tapped as to feed the aerial with two components displaced in phase-quadrature, and each separately keyed. The resultant radiation will be constant in frequency but may be displaced in any of eight alternative phase-positions, of which four components in quadrature may be utilized for two channels of phase-reversed signalling. The signals are relatively secret since the ordinary type of receiving apparatus does not distinguish between positive and negative waves. The waveband necessary even for multiplex transmission is narrowed down to that of a common carrier frequency and side bands. Finally the effective power of the generator is doubled because it transmits continuously instead of intermittently.

Abstract: An injection radiation source comprises a body of gallium phosphide containing a solid solution of zinc (0.0005-0.01 weight per cent) and tin and/or germanium (to a concentration less than that of the zinc). The presence of the tin or germanium enables the zinc to be incorporated into the body from a melt without the presence of oxygen.  The material may be prepared by first forming gallium phosphide from a gallium-phosphorous melt, preferably containing 5-20 times excess of gallium, and then heating the phosphide in a hydrogen atmosphere with a small quantity of zinc and tin and/or germanium for 3 hours at 1220 DEG  C. and cooling, e.g. over two hours, to 800 DEG C., cooling, and washing to remove excess gallium in 36% HCl. The light source may be formed by alloying pellets of gold-4 w./o. zinc (forming an ohmic contact), and tin (forming a rectifying contact) on to the phosphide and soldering tin-clad copper leads to the pellets, and produces an orange-red radiation (which may be coherent) with maxima at 7000 A and 5750 A.
