Abstract: A synthetic resin composition comprises a water-swellable linear or cross-linked polymer having as essential monomeric ingredients (1) one or more alpha-beta dibasic acids or anhydrides; and (2) a vinyl alkyl ether in which the alkyl group has from 1 to 10 carbon atoms, and from 0 to 20 per cent by weight of the said monomers of another monoolefinically unsaturated compound copolymerizable with said monomers, and/or partial esters, partial amides or partial alkali metal or ammonium salts of said polymers and 8-hydroxy quinoline, which acts as a stabilizer when the polymer is dispersed in water to form a mucilage.  The polymer may be cross-linked by incorporating a polyunsaturated cross-linking agent as an additional monomeric ingredient.  The dibasic acid or anhydride may be maleic, chloromaleic, 2,3 - dichloromaleic, 2,3 - dicyanomaleic, 2,3-dimethyl maleic, 2,3-diphenyl maleic, 2,3-dibenzyl maleic, 2,3-di-(p-methylphenyl) maleic, 2,3-dicyclohexyl maleic, or 2-methyl-, 2-ethyl-, 2-cyano-, 2-propyl-, 2-phenyl-, 2-benzyl-, 2-(p-methylphenyl) or 2-cyclohexyl maleic anhydride or acids corresponding thereto.

[Class 47 (i).] Relates to alarm systems wherein a pressure fluid is automatically released to operate a whistle or other alarm when the temperature reaches a predetermined point. A reservoir a for compressed air is connected by a distributor b to pipes c carried around the area to be protected. Each pipe c is provided with one or more automatic valves d each of which controls the passage of air to a pipe e. The pipes e terminate in a combined indicator and alarm box f. This comprises visual indicators g corresponding to the pipes e, and a valve j which is adapted to be opened by any indicator g. When opened, it admits pressure air from the pipe k to a whistle on the valve and also to a pipe m leading to a central bell or alarm q. In a ship, a box f is provided for each side of the ship, and a pipe r conveys pressure air to an alarm in the engine-room. The valve d, Fig. 2, comprises a ball valve 10 or mushroom valve which normally closes communication between the pipes c, e. It is held closed by a pin 12, lever system, 15, 27, and fusible link. As shown, the latter comprises two straps 29, 30 threaded through a fusible block 31 and detachably looped over spring arms 28, 32. The valve may be tested by pulling down the arm 28. A strainer 24 is provided for the pipe c, and the valve body is enclosed in a heatinsulating casing 34. The box f, Fig. 5, comprises a series of pistons g working in cylinders 41 to which the pipes e are connected. When a valve d opens, the air forces up the corresponding piston, giving a visual indication. The piston tilts a lever h common to all the pistons, the lever opening the valve j by means of a pin 43 and lever 15<1>. Compressed air from pipe k then has access to a pair of whistles 44 and to the pipe m. The pistons are retained in their raised positions by springs engaging grooves 47 in their stems.

Title: Method of dissolving eltasomers
IPC: C08J3/11
Filed: 1965-01-28
Abstract: An elastomer (including ethylene-propylene terpolymers) is dissolved in an organic solvent by a process which comprises simultaneously: Subjecting the elastomer in particulate form and while suspended in the organic solvent to compressive and shearing actions that distort and mangle the elastomer particles and extend the surface area thereof;  Subjecting the surfaces of the elastomer particles to the scrubbing action of streams of solvent in rapid movement with respect to said elastomer particles, thereby stripping from the particle surfaces the gelatinous layer formed by absorption of solvent; and Subjecting said stripped-away gelatinous layer to mangling, disintegrating actions to dissolve it in the solvent.  The particulate elastomer may be in dry form, or in wet crumb form in which case a water emulsion of elastomer is produced which may be broken to recover a water-free solution.  The process is preferably carried out by feeding a suspension of elastomer particles in solvent continuously through a rotary gear pump.

Abstract: 778,596. Exciting alternators. SIEMENSSCHUCKERTWERKE AKT.-GES. Feb. 8, 1956 [Feb. 9, 1955], No. 3998/56. Class 35. An alternator 1 is compound excited through rectifiers 3 by means of an excitation transformer 4 having tapped primary and secondary windings. Of the secondary winding, part c feeds the rectifiers and part d carries the load current; while the centre-tap of the primary winding is connected to the output voltage through a regulating resistor 10, and the part-windings a and b are connected to resonant inductances 5 and condensers 6 respectively. By this means the sum of the resonant currents is available in the transformer primary winding for voltagecomponent excitation of the machine, while the regulating device 10 only has to carry the losscurrents. The regulating resistor 10 may be replaced by a phase-shifting transformer, or a simple transformer fed through a magnetic amplifier.

The medium may be formed with only one adhesive strip which is protected before use by a covering (76, Fig. 5, not shown) or it may be formed, as shown in Fig. 6, with two adhesive strips 46, 50 which stick only to each other; the medium may be formed with adhesive strip 50 spaced from the adjacent edge of the strip, a line of weakness being formed adjacent strip 50, the medium being bent about this line of weakness and the part between it and the adjacent edge being clamped in a slot 40 in the drum 12 using a clamp 92 operated by a rotatable member 42, the medium being split along the line of weakness when it is removed from the drum. A plurality of sheets of recording medium, each formed with tear strings may be mounted on top of each other around the drum (Figs. 12, 13, not shown) to form a magazine. The surface of the drum may be formed with a plurality of longitudinal slots to guide the cutter wheel; it may alternatively be a soft surface to allow the cutter wheel to penetrate it. The head 16, which also carries fibre optics 36, a light source and a photo-detector for use in a transmitting mode, is moved to provide the frame scan by rotating a shaft 20 on which head 16 is mounted by three skewed rollers (215, Figs. 20, 24, not shown) which are disengaged from shaft 20 when the cutter wheel is in use, rotation of a frame carrying the cutter wheel so as to bring the cutter wheel into operational position also operating a pressure-actuated switch (230, Fig. 23, not shown) to de-energize recording stylus 38. The head 16 also carries a soft roller (116, Fig. 2, not shown). Signals derived from a scanned orginal are fed to a voltage controlled oscillator (304, Figs. 25, 26, not shown), black signals being transmitted as a signal of frequency 2400 Hz and white signals as a signal of frequency 1500 Hz. The signals are demodulated as described in Specification 1,471,384 by being clipped and passed to a balanced modulator (326) whose output is passed to a filter and to a voltage controlled oscillator the output of which is fed to another input of the modulator. The phase-locked loop of the modulator and voltage controlled oscillator inherently doubles the fundamental frequency of the frequency modulated signal and the filter removes signals in the frequency range 3000-4800 Hz.
