Title: Emulsions of ethylene polymers and interpolymers
IPC: C08F265/02
Filed: 1948-04-16
Abstract: Aqueous emulsions of ethylene polymers are prepared by polymerizing ethylene, alone or with interpolymerizing constituents, at a temperature between 50 DEG  and 1400 DEG  C., and a pressure above 200 atmospheres, in the presence of water, a water-soluble salt of a carboxylic acid polymer of molecular weight above 300, and an organic sulphonic acid or derivative thereof, preferably sodium oleo-p-anisidide sulphonate.  The water-soluble salt of a carboxylic acid polymer may be an ammonium salt of polymethacrylic acid, a sodium or ammonium salt of a saponified ethylene/maleic anhydride interpolymer or an alkalimetal salt of a glycollic acid ether of cellulose or of polyvinyl alcohol.  The reaction may be carried out continuously by introducing the reactants into a reaction vessel maintained at the required temperature and pressure and continuously withdrawing the emulsion and unconverted ethylene.  Interpolymerizing constituents mentioned are vinyl acetate, vinylidene chloride, carbon monoxide and formaldehyde.  The process may be carried out in the presence of hydrogen which modifies the properties of the polymer. An ethylene polymerization catalyst such as oxygen, a peroxy compound, particularly an alkyl peroxide, or an azo compound may be utilized, and there may also be present an inorganic salt such as sodium sulphate or a small proportion of an inert organic solvent such as benzene.  The emulsions obtained may be used for coating or as adhesives for fabrics or for making powdered ethylene polymers and interpolymers by precipitation.

Title: Improvements in and relating to arbitrary function generators
IPC: G06G7/164
Filed: 1952-04-28
Abstract: 694,560. Photo-electric function generators. BRITISH THOMSON-HOUSTON CO., Ltd. April 28, 1952 [April 26, 1951], No. 10650/52. Class 40 (iii). In an arbitrary function generator, the electron beam of a cathode-ray tube is deflected along one axis by a time variable electrical input and along the perpendicular axis by a repetitive timebase, and the graph of an arbitrary function of the input variable is drawn on the tube screen, operative when crossed by the moving spot to momentarily interrupt light from the tube screen falling on a photo-cell, the resultant variation in the output of which triggers the timebase to start a new sweep cycle; whereby the envelope of the spot deflection along the second axis is limited to the periphery of the functional curve, and a demodulating or filtering circuit energized by the time-base output waveform develops an output signal representing the desired arbitrary function of the input variable. Fig. 1 shows a cathode-ray tube 1 having an electron gun 2, X-plates 3, 4 energized by an electrical function of time X, and Y-plates 5, 6 energized by a repetitive saw-tooth sweep voltage from generator 10. The curve 9 of an arbitrary function is drawn on the fluorescent tube screen 8 in grease pencil and when crossed by the moving spot momentarily interrupts the illumination of a photo-cell 12, the resultant pulse in whose output is amplified by cathode follower triode 22 of amplifier 13 (Fig. 3), to trigger a conventional multi-vibrator 11 comprising cathode coupled triodes 25, 26. The latter changes over to momentarily positively pulse the grid of gas triode 28 to discharge the condenser 30, normally charged through series resistance 29 in a conventional saw-tooth generator circuit 10, thus energizing the Y-plates to commence a new saw-tooth cycle so that the maximum Y-deflection amplitude over a series of cycles is limited to the envelope of the functional curve 9. An adjustable bias source 33 is connected in the Y-plate connection to define the baseline 9b of the Y-deflections, and the time-base waveform is applied, e.g. to a low pass filter 14 comprising resistance 34 in series with capacitance 35 to develop a voltage representing the envelope of the Y-time-base waveform excursions and thus the functional curve 9, which is connected to output terminals 36, 37 in series with a variable bias source 35a establishing the zero level 9a. The cathode-ray tube may be initially connected to display the curve of a function derived from computing apparatus, which may be "stored" by marking with grease pencil so that by connecting the cathoderay tube in the above circuit the stored function may be reproduced indefinitely as input to a further computer. Magnetic deflection may be employed and the input and output signals may be respectively converted from and to mechanical motions by known devices.

Abstract: 343,379. Electric clocks. INTERNATIONAL TIME RECORDING CO. OF NEW YORK, Endicott, New York, U.S.A.-(Assignees of Thomas, F.; 27, West 11th Street, New York, U.S.A.) April 9, 1930, No. 11295. Convention date, May 2, 1929. [Class 139.] A synchronized clock system in which the normal impulses (e.g. one a minute) and the synchronizing impulses are sent over a single circuit, has secondary clocks each with a magnet having two armatures, one for driving the clock hands and one for removing (when an increased e.m.f. is transmitted) abutment means which normally arrest the hands near the synchronizing time. At the master clock contacts 14, 16 are closed once an hour, contacts 17 once a minute, and contacts 19 by the escapement 11. .At each minute impulse a circuit G, B, 32, 33, 17, 34, G is closed. Magnet 34 closes contacts 35 and an impulse is sent over circuit G, B (in part), 42, 43, 35, 37, 21, G to advance the secondaries. For thirty seconds before the fifty-ninth minute of the master clock, contacts 16 close and 19 send rapid impulses to step-up any slow secondaries. At exactly the fifty-ninth minute contacts 14 close to energize magnet 40, which closes contacts 43a and opens 43. An impulse of increased e.m.f. then passes to the secondaries over G, B (full), 42<1>, 43a, 45, 35, 37, 21, G. In each secondary clock, at each minute impulse, the magnet 21 and its armature and pawl 21a advance the hands until they indicate the fifty-ninth minute, whereupon they are arrested by a lug 23 on the ratchet 22 meeting a finger 25 carried on a second armature 24. Spring 26 is stronger than spring 26a so that, only when the impulse of increased e.m.f. is sent at the fifty-ninth minute of the master clock, is the magnet 21 able to attract this armature 24 and release the wheel 22, the clocks thereby restarting correctly. Specification 261,258, [Class 139, Watches &c.] is referred to.
