Title: New and improved means for eliminating magnetic coupling between coils
IPC: H01F27/36
Filed: 1924-09-01
Abstract: 231,820. Hazeltine Corporation, (Assignees of Hazeltine, L. A.). April 7, 1924, [Convention date]. Thermionic amplifiers and detectors.-Magnetic coupling between coils or transformers T1, T2 is eliminated by placing the coils so that the equation tan # tan #<1>=2 is satisfied, where # and #<1> are the respective angles between the axes of the coils and the line joining their centres. When the axes are parallel, as shown in Fig. 2<b>, the angles # and #<1> are each approximately equal to 55. When the coil axes are not in the same plane, the angle #<1> is measured between the line of centres of the coils, and the projection of the axis of one coil on the plane containing the line of centres and the axis of the other coil. Fig. 2<a> shows the arrangement of an aerial coil T1, and a series of intervalve transformers T2, T3 in a multivalve wireless set. Each coil or transformer is fixedly mounted on the base-plate of the corresponding variable condenser, the axes of the coils being parallel to each other and to the panel, but set at 55 to the line joining their centres. The corresponding circuit, shown in Fig. 2d, is similar to those described in Specifications 222,895 and 223,181, condensers Cn for balancing out capacity coupling being connected between the gr´d of each high-frequency valve and an intermediate point of the secondary coil of the following intervalve transformer. Fig. 3<a> shows a modified arrangement of the coils, each coil forming one member of a variable coupling for use in the circuit shown in Fig. 3b. In this circuit, the aerial is tuned by a condenser C1, and the aerial coil L1 is invariably coupled to a coil L2 forming part of a secondary circuit including a second coil L3 and a variable condenser C3. The grid circuit of a valve detector is connected across the condenser C3 and the plate circuit includes a reaction coil L4 variably coupled to the coil L3. The form of variocouplers used are those in which the axis of one coil is set at 45 to the spindle on which the movable coil turns. The coils L1, L3 are therefore so fixed in position that their axes are inclined at 45 to the moving spindles of L2 and L4, and are also inclined at 55 to the line joining the centre of L1 and L3. The secondary coil L2 is associated with a second coil L2 having one end unconnected, for the purpose of neutralizing capacity coupling between the coils L1, L2, as described in Specification 222,894. Capacity coupling between the condensers C1, C3 is prevented by enclosing them in electrostatic shields.

Title: Improvements in or relating to a system for the protection against fumes resulting from fires in buildings
IPC: A62C2/06
Filed: 1948-08-11
Abstract: 639,519. Removing fumes from buildings. SHEPHERD, G. R. (Otis Elevator Co.). Aug. 11, 1948, No. 21196. [Class 137] [Also in Group XXX] One part of a building is protected against fumes from a fire in a second part connected thereto by an opening, by a collection duct in the second part adjacent to the opening, and an exhaust fan which is started automatically when a fire occurs and sucks air and fumes into the collection duct for discharge to the atmosphere. As shown, the invention is applied to a building the floors of which are connected by moving stairs, the apparatus being in operation to prevent fumes from a fire on floor 2 from passing upwardly through the stairway openings. A collecting duct 8 is arranged around three sides of each opening, which is obstructed on the fourth side by the stairway, and has inlet slots 10 along the bottom of its outer walls. The ducts 8 are connected by ducts 11 to a vertical duct 12 leading to the fan 16 on the roof. The fire would, as is usual, start a sprinkler 27 causing a waterflow which moves a member in the supply pipe to the sprinklers for that floor. This member, on moving, closes a switch which initiates the opening of a pivoted damper 13 in the corresponding duct 11  by exciting a solenoid 15 and withdrawing a latch ; starts the motor 18 of the fan 16 ; withdraws a latch to release a pivoted trap door 23 to permit air to pass downwardly through the stairway openings to replace the air exhausted by the fan 16 ; stops the movement of the stairs so that people may run down the stairs to the street ; stops the normal ventilating system, or that part of it serving the affected floor ; sends an alarm to the fire station ; starts alarms on all floors ; and starts a fan which ejects air at the vestibule and thereby prevents an inward and upward flow of air through the stairways which would interfere with the down current. Sprinklers 31 are arranged around and in close proximity to the ducts 8, the sprays meeting just below the affected duct and impinging on the duct so that some spray is sucked into the duct for cooling purposes, and some falls vertically from the duct to form a curtain within which people can descend the stairs. The sprinklers 31 are started automatically when one of a number of pilot sprinklers 32 more remote from the opening than the sprinklers 31, lets go, the supply to the pilot sprinklers being then shut off. The sprinklers 31 may be arranged on the soffit of each stairway to fill with spray the stairway next below. The system may be put into operation by means other than the flow to a sprinkler, e.g. by a thermal responsive switch by a photo-electric device operated by smoke, or by a manually operated switch. The invention may be applied to the openings in a lift shaft, the exhaust fan being connected by ducting with a collecting duct above the access opening on each floor. The downflow of air is through the lift shaft an inlet opening being provided at the base of each lift-opening door panel.

Abstract: 820,246. Electrical component assemblies. SIEMENS EDISON SWAN Ltd. June 10, 1958 [July 4, 1957], No. 21211/57. Class 37. A method of providing an encapsulated assembly of at least two components, which have different requirements as to embedding materials, is characterized in that one component is first embedded in a body of moulding material, and is then placed with the second component in a mould, and the second component at least embedded in a second material such that the two embedding materials form a single integrated block. In the embodiment shown, a capacitor 1 is embedded in a generally rectangular block 2 of cold setting synthetic resin, e.g. an epoxy resin, having projecting lugs 3. The pre-moulded capacitor is then placed in a mould, leaving a space between the side formed with the lugs 3 and the wall of the mould, into which the coil 4 is inserted. A resilient embedding material, e.g. a mixture of epoxy resin and synthetic rubber is then introduced into the space around the coil and allowed to set, resulting in a composite block having a rigid part 2 and a resilient part 5.
