Title: Improved process for reversing periodically the direction of rotation of an electricmotor
IPC: H02P7/00
Filed: 1952-01-25
Abstract: 691,669. Magnetic switches; control of motors. ORGRYTEVERKEN AKTIEBOLAG. Jan. 25, 1952 [Feb. 6, 1951], No. 2168/52. Classes 38(iii) and 38 (v) A device for periodically reversing the direction of rotation of a motor which may drive a washing machine, and for providing a short interval of time between the actuation of two sets of contacts, comprises a tube 2 rockable about an axis 1 and containing a ball 3 or other member of magnetic material adapted to slide slowly down the tube till it comes adjacent a magnet or member of magnetic material mounted on a lever 13 and causes the lever to tilt about an axis 14 and actuate contacts causing the motor to rotate. The motor, in addition to driving the washing machine, drives a stud 6 about the axis 1 till the stud engages the end of a slot 5 in an arm 4 and carries round with it the arm 4 and tube 2, the tube sliding along the magnet. When the tube has passed its horizontal position, a spring 11 has been carried past a dead-centre position and tilts the tube rapidly into its other position adjacent another lever and magnet 13. The motor is now de-energized and the ball 3 slides slowly down the tube 2 at a rate determined by a valve 8 controlling the passage of fluid between the ends of the tube, and eventually actuates the second lever 13 and the contacts associated therewith causing the motor to rotate in the reverse direction.

Title: Improvements in or relating to electric insulators
IPC: H01B17/28
Filed: 1941-02-24
Abstract: 547,410. Insulators. REYROLLE & CO., Ltd., A., and KIRKWOOD, I. W. A. Feb. 24, 1941, No. 2463. [Class 36] A tubular insulator with a bend in it is made by winding into a straight tubular form a strip of paper of which part of the width is creped, and then bending the straight tube at a part where the material is creped. In Fig. 2, a strip of paper with a longitudinally creped central part D and plain edge parts D<1> is wound on a mandrel C under pressure from rollers E connected by a reduced part El clear of the creping ; the ridges of the creping may not be continuous. The mandrel may be ductile or may then be replaced by a ductile mandrel to permit bending at the creped part. Condenser layers of lead foil or metallized paper may be wound in and may be in echelon as at G, Fig. 4, or of gradually reducing width as at G<1>, Fig. 3. The marginal portions D<1> may be impregnated as by varnish or synthetic resin before winding, and heat and pressure applied during or immediately after winding to solidify them ; after bending, the bent portion is impregnated with the same or a different medium and converted into a solid mass in any suitable manner. Alternatively, the whole strip may be coated with a thermo-plastic &c. material not fully polymerized, the material being softened after winding to permit bending, or the whole strip may be unimpregnated until wound. Impregnation may also be effected by a liquid such as oil, or by a gas, the conductor alone maintaining the bent form. One or both ends of the insulator may be provided with a flanged bushing H. In place of longitudinal creping, the ridges may be at an angle to the length of the paper, or they may be crossed to give a lattice pattern.

Title: Improvements in electromagnetic-wave transmitting systems
IPC: H03H2/00
Filed: 1921-01-19
Abstract: 181,047. Roos, O. C. Jan. 19, 1921. Arc oscillation generators; harmonics, absorbing.-One or more undesired frequencies or harmonics from a high-frequency source are eliminated from radiation by means of tuned circuits associated with the antenna, such circuits offering a low impedance to each of the undesired frequencies but a high impedance to the particular frequency that it is desired to transmit. The invention is described in connection with an arc generator, and it is stated that one of the eliminated frequencies may be the fundamental, the selected frequency for radiation then being a higher harmonic of relatively short wave-length. 'The energy of the undesired frequencies so bypassed is rectified and fed back to the source. In the simple form shown in Fig. 2, the circuit C<2> P' L<2> is shunted across the arc A, and is so tuned as to absorb the undesired frequency whilst offering a high impedance to the frequency to be radiated. The energy of the absorbed frequency is translated to the secondary coil S<1>, and is rectified by the device V. The resulting unidirectional current is fed back to the arc through a regulator R (which may be a storage battery) and choke coils I<1>. In other circuit arrangements, a series of parallel-branch circuits are connected in shunt across the arc, having a maximum impedance at the frequency to be radiated, and one or other of the circuits offering a minimum impedance to the frequencies to be absorbed. The preferred form, in which two undesired frequencies are eliminated, is shown in Fig. 5. The circuit C<8> P<5> is tuned to one parasitic frequency, and the circuit C' P<6> to another. The circuit C' L<5> is tuned so that the total impedance of the shunt network is very high at the desired radiation frequency, which is therefore not diverted. The energy of the absorbed oscillations is fed to the rectifier V by the serially-connected secondaries S<5>, S<6> and is passed back to the arc.
