Patent SE-7609498-L (SE)
Inventor: BALDWIN S H
IPC: D21J1/00
Filed: 1976-08-27
Abstract: Pressed fiberboard  is produced in an S-1-S type process at much shorter than normal (prior art) press cycles.  The process includes the use of fiber furnish having preselected shrinkage characteristics.  This furnish is wet formed into a mat either with or without a paper overlay, which overlay may be decorated or undecorated, depending on the desired end use and pressed wet as in the 5-1-8 process, using control means, such as stop bars in the hot press, to limit the final separation distance between the hot plates in each press opening to provide full caliper reduced density board.  By using a fiber furnish having selected shrinkage characteristics it has been found that the pressed board can be safely removed from the press in a semi-cured, moist condition, at unusually short press cycles.  The use of said fiber furnish also permits the use of higher than normal (prior art) press temperatures without incurring discolouration of the paper overlays. The board is then baked and humidified to complete the curing process.

Abstract: A method and machine for preparing an annular workpiece from tube stock, using a part-off rolling tool. The rolling tool is advanced radially of the tube stock to a depth approximately equal to the desired bore diameter of the workpiece so as to partially sever a length from the tube stock. The inside of the length is then machined to the desired bore diameter. The machining either causes the length to be fully severed from the rest of the tube stock or leaves it connected thereto by a thin annular band. In the latter case the rolling tool is then advanced further to fully sever the length from the rest of the tube stock.

Abstract: In a brushless D.C. motor employing a permanent magnet rotor 1 and a two winding stator 2, 3 with electronic switching 4, 5 responsive to rotor position to improve efficiency, switching of the stator current is initiated in advance of the rotor reaching its neutral position so that the stator poles have more or less completed their change by the time the rotor reaches the neutral position. However, as, on starting, the rotor might therefore oscillate back and forth instead of rotating an override circuit 14 is included. When the rotor starts from a position between (in the desired direction of rotation) the point at which switching is initiated and the subsequent neutral axis 35, the override circuit 14 maintains the initial condition of the switching circuit for a predetermined period irrespective of the rotor sensor 35 output during that period. <IMAGE>

Abstract: The brake comprises a pressure plate 6 arranged to urge brake lining 7 against a disc 10 to be braked by means of springs 8, the brake being released by moving a retraction bolt 4; in order to maintain the release stroke of bolt 4 substantially constant, regardless of the wear of the brake, release movement is transmitted to the bolt 4 by a clamping lever 14 which defines together with a fixed part 24 a wedge-shaped space into which can be drawn an actuating means 30 by means of an electromagnet 23. Upon electromagnet actuation the means 30 is moved to jam the clamping lever 14 upon bolt 4, whereas upon brake actuation upon de-energization of electromagnet 23 the lever 14 is free to be urged against the actuating means 30 by means of a spring 11; and the lever 14 is then slidable on bolt 4 to give automatic new compensation. The actuating means 30 compress rollers 15, 17. In the embodiment of Figures 3, 4 two brake linings (31, 32) are provided and a stirrup spring 34 replaces the compression spring 11 of Figures 1 and 2. <IMAGE>

Abstract: A microprocessor is provided in a television receiver which is responsive to a clock signal phase locked to a recurrent signal component of a composite video signal, such as a horizontal line rate signal component. The clock signal frequency is chosen to be an integer multiple of the recurrent signal component and to enable the microprocessor to execute an integer number of uniform instruction cycles during an integer number of periods of the recurrent signal component. The execution of the instruction cycles is brought into a real time phase alignment with the recurrent signal component by causing the microprocessor to execute an instruction during a time interval which is greater than the time required to execute one of the uniform insturction cycles. The phase of subsequently executed uniform instruction cycles is shifted in this manner until signal sampling indicates that the desired phase relationship has been achieved.

The piezoelectric motor includes a rotor and a stator, at least one of them incorporating a vibrator of mechanical oscillation, having a piezoelectric device connected to a voltage source and converting electric power into mechanical vibrations. The piezoelectric motor contains no windings and provides considerable driving torques, owing to the stator and rotor being urged against each other. The structure of the piezoelectric motor is determined by the arrangement of the piezoelectric device in the rotor and stator, the type of oscillation being excited, the shape of the piezoelectric device, the arrangement of its electrodes, their shape and electrical connection, as well as by the polarization of the piezoelectric material. Various combinations of these features offer a great variety of structures and designs of the piezoelectric motors, the piezoelectric motor being supplied from a voltage source with supersonic frequency.

Abstract: A method of casting metal into an electromagnetic crystallizer consists in continuously feeding the metal melt (4) into the inductor (1) of the crystallizer under the influence of the electromagnetic field of which the ingot (6) is formed, its crystallization starting on a bottom plate (2) of the crystallizer at such a frequency of the current passing through the inductor (1) which ensures the balance between the hydrostatic pressure of the metal melt and the electrodynamic pressure of the electromagnetic field of the inductor (1) at a given cross-section of the ingot (6). Along with the crystallization of the melt (4) the ingot (6) is continuously drawn away from the inductor (1) by moving the bottom plate (2). When drawing the bottom plate (2) from inside the inductor (1) the current frequency is increased by a value which is proportional to the decrease of the electromagnetic pressure of the inductor field (1).
