Abstract: ABSTRACT:            A magnetic device comprising at least one thin layer of a magnetizable material which shows an easy axis of magnetization which is substantially normal to the surface of the layer. Magnetic domains are propagated in the layer. The propagation occurs under the influence of a bipolar current, for example an alternating current, through a pattern of electrically conductive material with which the layer is provided. Means are furthermore present which cause an asymmetry force and thus determined in which direction the domains are propagated. The pattern and the elements are present in a single configuration which is constructed from at least a layer of magnetic material.   In a first case one layer is present in the configuration consisting of electrically conductive soft-magnetic material. In the second case the configuration comprises a layer of electrically conductive material and a layer of soft-magnetic material. In a third case-the configuration comprises a layer of electrically conductive material and a layer of permanent magnetizable material, which latter causes an asymmetry force in the magnetized state.

Abstract: BRAKE ACCELERATOR FOR A FLUID-PRESSURE BRAKE     SYSTEM HAVING A BRAKE CONTROL VALVE Abstract of the Disclosure A brake accelerator for a fluid-pressure brake system particularly for railway vehicles has a control chamber connected through a throttle orifice to a brake line.  The brake system includes a control valve in which is an emergency brake piston one side of which is subjected to brake line pressure and the other side subjected to pressure in the control chamber.  A second control chamber is connected by a first passage to the brake line and a normally closed first valve is in the first pas-sage which valve is operable to an open position by the emergency piston in response to a pressure drop in the brake line.  The first passage also includes a normally open second valve.  A second passage connects the second control chamber to the atmos-phere and a control piston is disposed in the second passage to close the second valve and to define in the second passage a normally closed third valve.  Pressure fluid entering the second control chamber from the brake line upon opening of the first valve when a decrease in pressure occurs in the brake line in-creases the pressure in the second control chamber so that the increased pressure acts upon the control piston to open the third valve to enable pressure fluid to be drawn off to the atmosphere from the second control chamber and to close the second valve.  A spring moves the control piston to close the third valve and to open the second valve when the pressure in the second control chamber drops below a predetermined value so that a limited quantity of pressure fluid is drawn from the brake line by the accelerator.

Abstract: WEB PRINTING PRESS     ABSTRACT OF THE DISCLOSURE      The invention relates to a continuous offset lithographic web printing press capable of printing a series of relatively short runs without interruption and with minimum waste of web material.  The press is characterized by a plurality of individual printing units with a motor for each unit and through which units a web runs continuously.  During a given run, a portion of the printing units is in a printing mode, and another portion of the printing units is in a nonprinting or thrown-off mode during which time the web moves through the unit or units thrown-off while those units are made ready for a succeeding run.  Each motor of each unit is capable of driving a plurality of printing units as well as auxiliary equipment such as a web infeed and folder.  A clutch is interposed between each unit and a common drive line for all the units and for the infeed and folder.  When the clutch for a given unit is energized, the motor for that unit then applies driving torque to the main drive shaft for driving the auxiliary equipment.          Each printing unit also includes apparatus for throwing the printing cylinder or cylinders from the web and upon throw off for changing the attitude of the web between a printing attitude, and a nonprinting or free running attitude in which contact of the web with the printing cylinders is prevented.  A control system is provided and enables shut-down of and throw-off of the printing unit or units engaged in the first run at the end of a preset count and start-up of the unit or units engaged in the next run.  On start up of a unit, the control system brings the printing blanket cylinder or cylinders up to speed, causes throw on of the dampener and inker, and then at the appropriate time causes blanket cylinders to be thrown-on.  The control system includes mode select circuits so that any one or all of the printing units may be used for printing a given job.

Abstract: A B S T R A C T This invention consists of a new type of valve con-struction for internal combustion engines.  Each of these valves is made of a thick circular metal disc, the rim of which is smooth and at right angles to the face.  At one location on its perimeter, the disc is provided with a cavity which is partly in the face and partly in the rim.  The valves rotate on a common shaft which is activated by the usual timing gears from the crankshaft.  The valves are located directly above the top of the cylinders, so that their rims make contact with, and cover the intake and exhaust openings in the combustion chambers, when the valves are closed.  However, when the cavity of the valve is directly above an opening, contact is made between the combustion chamber, and the valves are considered to be in an open position.  Rotation to the valve-shaft is provided by timing gears from the crankshaft.  A variation in the design of the valves consists of the cavity being provided centrally and entirely at one location in the rim.

Abstract: Abstract of the Disclosure For scoring of simulated firing of a weapon, having flatwise-angularly sweeping beams of radiation, emitted at the weapon location during a period beginning at or about the instant of simulated firing are used for measuring the position of a traget retroreflector in range and in functions of azimuth and elevation.  During the same period a calculation is made of the instantaneous positions in range, and in functions of azimuth and elevation, of an imaginary projectile fired from the weapon at the firing instant under conditions then existing, and the relationship is ascertained between the imaginary projectile and each beam in its angular position at interception by the retroreflector.  At, a scoring instant, when weapon-to-reflector dista?ce equals weapon-to-pro-jectile distance, or when the projectile is at a prede-termined elevation relative to the reflector, scoring is based on the relationship of projectile to angular beam position at that instant.  Scoring results can be dis-played at the weapon location and/or transmitted to the target in beam modulation for evaluation of hit effect at the target.
