[Class 103 (i)] [See also Group XXXV] A spring-applied electromagnetically released brake comprises brake shoes 10, 20 mounted on pivoted arms 12, 22 drawn together by a spring 18 but held apart by a rod 25 which bears against an adjusting screw 26 at one end and at the other against a stop 24 on a lever 19 moved by an electromagnetic device 27 so that movement of the device varies the braking pressure. Adjustment is effected by the screws 26, 34. Stops 32, 33 are provided on the electromagnetic device to limit its movement. The electromagnetic device comprises a stator on which two sets of coils are mounted, each set on alternate poles and a rotor having poles normally displaced with respect to the stator poles. The poles are shaped so that the variation in magnetic reluctance for a given angular movement decreases as the part moves into the magnetic field. The balance of pull exerted by the device on the movable member of the brake thus decreases as this member is moved in pulling off the brake. The brake is used in a speed-regulating means adapted to give slow running of an electric motor, the current in one of the windings of the electromagnetic device 27 being arranged to vary inversely as the speed of the motor. The second winding is energized when it is desired to cut out the constant speed control and release the brake entirely for high speed running.

Abstract: 1,070,914. Esterification. IMPERIAL CHEMICAL INDUSTRIES Ltd. Feb. 15, 1966 [Feb. 24, 1965], No. 7967/65. Heading C2C. In esterification (including transesterification) processes in which a metal or a metal compound is used as a catalyst, the catalyst is separated from the esterification product by treating the product with activated carbon at a temperature not exceeding 200‹ C. Part or all of any unused alcohol may be separated from the esterification product before the treatment with carbon. Also, the catalyst may first be converted into a different form, e.g. by precipitating a titanium or zirconium compound by means of lime. The process is particularly applicable to the treatment of products obtained by esterifying phthalic anhydride with an alcohol or mixture of alcohols containing 4-14 carbon atoms produced by the " OXO " process, and comparative experimental results are given of the esterification of phthalic anhydride with iso-octanol (produced by the " OXO " process) in the presence of the titanium tetra-alkoxide of iso-octanol as a catalyst. A number of other metals which may constitute the catalyst or from which the catalyst may be derived are specified.

[Also in Divisions G6 and H1] The control rod of a nuclear reactor has a ferromagnetic head 32 held by an electromagnetic grab 12 comprising a mild steel core 33 providing a central polepiece 34, a magnetising coil 35 with insulation capable of withstanding high temperatures, a mild steel cylindrical casing 37 to the lower end of which are welded four mild steel fingers 38, a mild steel web 39 integral with the upper end of the core 33,and a stainless steel web 42 welded to the lower end of the core 33. The head 32 completes a mild steel circuit for the magnetic flux caused by energization of the coil 35, which circuit is not short-circuited by the stainless steel web 42. The size of the magnetic flux through the circuit is detected by a search coil 36 which thus provides an indication as to whether or not the control rod is engaged by the grab. Disengagement of the control rod from the grab on de-energization of the coil 35 to provide emergency control is assisted by a pin 43 slidable in a bore extending axially of the core 33 and carrying above the web 39 a bellows seal 45 which prevents entry of coolant into the grab through the bore. A stainless steel extension 41 of the casing 37 houses a solenoid 47 wound around a tubular former 48 in which slides a piston 49 carried at the upper end of the pin 43. The piston 49 is loaded by a spring 51 bearing against a plug 52 screwed into the end cap 53 of the extension but is retracted into the solenoid 47 against the action of the spring when the solenoid is energized. The solenoid 47 and the magnetising coil 35 are connected in series so that the pin 43 is withdrawn when the control rod is carried by the grab but is sprung through the core 33 to strike the head 32 of the control rod when this is to be disengaged from the grab. A tubular plunger 13 extends vertically upwards from the grab and at its upper end is connected to a motor-driven rack and pinion so that the control rod may function as an operating as well as an emergency control rod.
