Patent GB-947052-A (GB)
Title: Polyspirane resin dispersions
IPC: C08K5/12
Filed: 1960-02-16
Abstract: A coating composition comprises an aqueous dispersion of a polyspirane resin (as defined in Specification 938,781) and, as curing agent, an acid ester of a polycarboxylic acid, having at least one half-esterified anhydride-forming pair of carboxyl groups and being soluble in water or an aqueous mixture of an organic solvent. The compositions yield, on heating, cured, cross-linked products suitable for electrical insulation. They may include other compatible polymers e.g. water-dispersible phenol-aldehyde resins. The polyspirane dispersions are produced by polymerization of a dialdehyde and a polyhydic alcohol in water. The preferred polyhydic alcohol is pentaerythritol (if desired containing some dimer.) Suitable aldehydes are succinaldehyde, glutar-aldehyde, serbecic or azelaic or sebacic dialdehyde or phthalic aldehyde. The compositions may include cure promoter, e.g. water-soluble salts of lead, lithium, cobalt, manganese, calcium, zinc, iron or cerium, e.g. zinc acetate dihydrate or zinc borate. Solvents which may be added to the aqueous dispersions are for example, dioxane, dimethyl sulphonide, alcohols or dimethyl formanide.  In Example (1) a mixture of 1,3- and 1,4-diethyl esters of pyromellitic acid in ethanol, and zinc acetate dihydrate are added to an aqueous dispersion of poly (glutardiylidene pentaery-thritol), and the composition coated on to wire, dried and heat-cured at 300-400 DEG C.  Other examples are similar. Other curing agents mentioned are acid esters of methyl succinic acid, maleic acid, or hexachloro-endomethylene tetrahydrophthalic acid. Esters of the anhydrides of their acids or of pyromellitic acid with polyhydric alcohols, e.g. ethylene or butylene glycol, dimethyl hexane diol or glycerol are also useful. Also useful are acid esters of polymeric polyacids, e.g. of a copolymer of maleic acid and ethylene.

Abstract: 1354036 Web treatment apparatus BRUCKNER APPARATEBAU GmbH 8 Feb 1972 [25 Feb 1971 8 June 1971] 5681/72 Heading D1L Apparatus for the wet treatment of a continuous textile web 1 comprises a vat 2 containing a treatment liquid, a rotatable compartmented drum 3 having vanes 3a disposed round its circumference to form the compartments, means (not shown) for rotating the drum intermittently by one compartment at a time, conveyor means 5 disposed upstream of the vat for feeding the web 1 into the compartments of the drum 3, conveyor means 6 disposed downstream of the vat for removing the treated web and a web sensor 8 arranged above the vat to control and synchronise via switch 9 and control means (not shown) the rotation of the drum and the speeds of conveyor means 5 and 6. The web sensor 8 is moved by the web between two operative positions; the first (illustrated) adopted when the treated web is still present in uppermost compartment of the drum and a second (Fig. 2, not shown) when the uppermost compartment is empty. In operation the rotation of the drum is controlled by a timing device so that under ideal conditions filling and emptying of the respective drum compartments is synchronised. When however the web 1 shrinks more or less than expected during treatment the situations arise where the timing device issues the signal for the drum to be rotated long after or before the uppermost compartment of the drum has been emptied. These states are sensed by the web senser 8 which then acts on the conveyor means 5 and 6 to produce increased or decreased filling or speeds of emptying of the compartments and/or the rotary drive of the drum to brake the drum until the sensor 8 operates switch 9. The partitions 3a of the drum 3 may be perforated and include broadened sections 3b at their outer edge to prevent damage of the web. Pivoting loading device 7 is provided to load the web 1 into the drum compartments in a piled condition.

Title: Improvements in and relating to electrical control systems
IPC: G05D3/14
Filed: 1942-05-01
Abstract: 609,303. Transformers. TUSTIN, A., MORRIS, D. G. O., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. May 1, 1942, No. 5924. [Class 38 (ii)] [Also in Group XXXVIII] In a system in which an alternating voltage dependent in magnitude on a controlling quantity controls the magnitude of a controlled quantity, an alternating voltage having lagging harmonic components corresponding to harmonic components in the amplitude of the control voltage is derived directly or indirectly from that voltage and is injected into the control circuit in opposition to the control voltage. This amounts to phase advance of the harmonic components of the original operation in accordance with rate of change of such components, and minimizes hunting. The arrangements described comprise positional control systems, but the invention is also applicable to self-regulating systems. Phase retarding devices. The device shown in Figs. 1 to 3 comprises two pairs of toothed unwound rotors and wound stators 4, 1 and 5, 2, the rotors being carried on a shaft 6 biassed to a normal position by spring 16 and damped magnetically by a disc 13 and magnets 14. The rotors are angularly displaced and, normally, their teeth are disposed symmetrically as shown with respect to the position of maximum registration with the teeth of the stators. Stator windings 18, 19, which may be combined as a single winding, are fed with the constant A.C. from which the control A.C. is derived and windings 20, 21, connected in series in the circuit carrying the alternating control current, are arranged respectively to assist and oppose the corresponding constant A.C. windings, or vice versa when the phase of the control A.C. reverses. When control A.C. is absent, the torques on the two rotors balance, but control A.C. increases the torque on one rotor and reduces that on the other, so that shaft 6 rotates against the action of spring 16 controlled by the damping device and inherent inertia so that the flux over one pair of stators and rotors increases while the other decreases. The voltages induced in the control windings 20, 21 from the constant A.C. windings 18, 19 are thus increased and reduced respectively, or vice versa, and the resultant voltage from the opposed control windings has lagging components due to the action of the damping device and inertia. In a modification referred to later, rotation of the rotors is effected indirectly by a torque motor controlled by D.C. derived from the control A.C. A further modification, Fig. 9, comprises a core carrying windings 41, 42 supplied with constant A.C. and a rotor carrying a coil 47 connected in the A.C. control circuit. The shaft of the rotor is arranged with a biassing spring and damping as in the first arrangement and operates to produce the same effect due to the presence of control A.C. directly or by means of the D.C. torque motor referred to. Specifications 592,208, [Group XXXVIII], 609,294, 609,296 and 609,304 are referred to.
