Title: Improvements in controllers for electric motors
IPC: H02P5/69
Filed: 1932-10-04
Abstract: 399,316. Field control of two D.C. motors. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.- (Assignees of Stansbury, C. ; 12th Street, Milwaukee, Wisconsin, U.S.A.) Oct. 4, 1932, No. 27537. Convention date, Oct. 5, 1931. [Class 38 (iii).] With a controller 15 in its " off " position shown, the armatures of two motors M, M1, mounted on a common shaft, are disconnected from the supply, but a self-maintaining relay 17 is energized to insert a variable resistance 9 in series with a separately excited field 3 of the motor M, and to connect the field 4 of the motor M1 in a closed loop with a resistance 16. When the controller 15 is moved to either of its " forward " or "reverse" positions the armatures of the motors M, M1 are connected in series across the supply, but the motor M1 is not effective, and the driven machine, which may be a pipe coupling screw-on machine, is driven at high speed by the motor M alone, the field of which is weakened by the resistance 9. Towards the end of the screwing-on process, the armature current increases to operate a relay 26 which de-energizes the relay 17, thereby short-circuiting the resistance 9, and connecting the field of the motor M1 directly across the supply, so that both motors are strongly excited, and both share in the heavy torque required for the final screwing on. Fluttering relays may be employed to prevent too sudden changes in field strength. The Specification as open to inspection under Sect. 91 comprises also an arrangement in which the field windings of both motors may be varied in magnitude, and in the case of one also in direction, at will. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the treatment of bituminised or tarred road and like surfaces
IPC: E01C7/18
Filed: 1945-10-23
Abstract: 602,770. Road surface treatment. VIALIT CO., Ltd., and BRUCKMAN, K. Oct. 23, 1945, No 27942. [Class 107] In a process of treating tar or bituminous road surfaces in situ by hydrocarbon oils are applied thereto under such conditions-e.g. by spraying at high velocitythat they penetrate the tar or bituminous surface to soften it, the thus softened surface then being caused to flow under the action of a road roller to fill up or cover bare patches of road by the squeezing out of the adjacent built up portions of bituminous surface. The oils used are of relatively low viscosity and preferably contain a proportion of phenolic bodies, and may be e.g. a mixture of gas oil and anthracene or creosote oil, or a viscous fuel oil and anthracene oil or creosote, and may be or may contain a proportion of a polymerisable or otherwise resinifying material.
Patent GB-447870-A (GB)
Title: Improvements in or relating to a process for the manufacture of rubber articles
IPC: C08J5/02
Filed: 1935-10-10
Abstract: In the manufacture of rubber articles having determinate portions of varying thickness by deposition of rubber on a form from an aqueous dispersion, a coagulant is applied to the surface of the form and the effectiveness of the coagulant is at least partially reduced in a determinately restricted portion or portions of the surface prior to the application of the dispersion.  An additional film of uncoagulated dispersion may be applied to the form prior to the application of the coagulant. Alternatively a dispersion may be applied to a form to the surface of which coagulant has been applied, the effectiveness of the coagulant which will have diffused through the rubber is then at least partially reduced in a determinately restricted portion and dispersion again applied to the form.  The coagulants, and solvents therefor, described in Specification 364,684 may be used. The effectiveness of the coagulant may be reduced by a chemical agent.  The effectiveness of most coagulants may be reduced by treating with alkaline agents, e.g. potassium hydroxide, ammonia, sodium bicarbonate; the alkaline agent may be dusted on in powder form or applied as a solution.  However with alkaline coagulants for use with acid dispersions it is necessary to use an acid to reduce their effectiveness.  The effectiveness may also be reduced by physical means, e.g. a portion of the coagulant may be removed by partially immersing the form with its coating of coagulant in a solvent to dissolve some of the coagulant off the form.  The solvent should preferably contain some of the coagulant to prevent removal of too much coagulant; thus a form coated by dipping with an alcoholic solution of calcium chloride may be partially immersed in a more dilute solution of calcium chloride in alcohol. The invention may be applied to the production of gloves, bathing caps, balloons &c. in which case the rubber is subsequently stripped from the form upon which it is deposited or it may be applied to the coating of metal &c. articles with rubber coatings in which case the metal &c. acts as the form and the rubber is not stripped therefrom.  Specification 382,305 also is referred to.
