Abstract: A cutting device for strip stock includes a stationary blade and a motor-driven, movable blade that continuously contacts against the stationary blade, constituting a point of support. Two other points of support for the movable blade are equally spaced from the cutting edge of the blade and from the sides of the blade. The other two supporting points also function as blade drive points for moving the blade in a reciprocating manner. The drive points are connected to an output shaft of the motor through a gear assembly. A pair of ball bearings on each side of the blade, which are laterally spaced from each other on each respective side of the blade, cooperate with the blade to achieve a very low friction for the device during operation.

Abstract: Relay with positively guided contact or contact sets, each contact being accommodated in a chamber and being at least partially separated from the adjacent contacts, and, furthermore, an actuator being provided for respectively opening and closing the contacts, the actuator being of multi-component design. The components of the actuator can be displaced with respect to one another here, the drive not acting on all the components of the actuator.

Abstract: Herein is described a process for the light-intensity balancing of an optical system, and a device for carrying out the process. The optical system consists of a light source, a lens installed in the beam path, and optoelectrical components that sends to an amplifier a signal that is proportional to the local light intensity. The intensity balancing is carried out by measuring and determining the intensity distribution in a plane. This local distribution is modified at the relevant points for the local distribution according to the optical properties of the lens until a uniform intensity distribution in the plane is obtained. The lens is attained by radiating its surface or internal structures with a laser.

Abstract: This invention relates to a tape winder for winding paper tapes, such as are particularly used as printed paper tapes in tape printer for documentation purposes, which tape winder comprises a driven reel hub, feeding and deflecting rollers and a tape tensioner arm. The reel hub is forklike and is laterally extractable to a limited extent and comprises preferably four winding rods, which are spaced 90.degree. apart so that the tape coil can freely be removed from the winder when the reel has been extracted.

Abstract: This invention relates to an electromechanically operable apparatus for severing strip, such as a paper tape or plastic film tape, which is dispensed by a power-operated dispenser. A swingable cutter blade is connected to a crank, which is operated by a gear train via an eccentric drive and a connecting rod, which is provided with a cam track cooperating with the crank. In dependence on the condition of the cam track and the sense of rotation of a motor for driving the gear train the extent of the angular movement imparted to the swingable cutter blade can be selected for the making of a complete cut or a partial cut through the strip.

Abstract: This invention relates to a pneumatic valve assembly for controlling a compressed air stream in response to a non-contacting actuation. It is desired to provide such a valve assembly which is adapted to control high working pressures without an intermediate amplifier. This is accomplished in that a pivoted one-armed or double-armed lever is provided with a permanent magnet on one side or on each of both sides of its pivotal axis and via a ferromagnetic or magnetic actuating member which is moved into the proximity of the permanent magnet or magnets and via a plunger causes a pilot orifice to be opened or closed, which orifice is adapted to be flown through by a pilot air stream for actuating a pilot piston for moving a valve piston to positions in which the valve is opened or closed.

Abstract: An apparatus for severing data-bearing tapes which are dispensed by a machine, which apparatus comprises an electric motor for driving a double-edged helical rotary cutter for cooperating with a spring-loaded stationary cutter, comprises an angle-section carrier, which is formed on the outside of one leg of said carrier with a concave recess extending along said one leg and receiving said rotary cutter, whereas the second leg of the carrier constitutes a bottom for mounting the motor, which is disposed in the spaced defined between the two legs, and the carrier is adapted to be cut to a length which matches the width of the tape to be severed.

Abstract: In an elapsed-time meter, which comprises indicating digit wheels, which are mounted in a housing and operable by an electric motor via an interposed transmission, the rotor of the drive motor is rotatably mounted at one end in a partition contained in the housing and at the other end in a mounting plate, which on the side that is remote from the partition carries the transmission and which is integrally formed with resilient lugs, which cooperate with detent noses carried by the partition to detachably fix the mounting plate in position.

Abstract: In a miniaturized electromagnetic relay wherein an insulation is provided in a housing separating the magnet and contact system, there are provided a rib integral with the housing having a dogleg for partially encapsulating the armature and a pocket on the actuator for the nesting of a free swivelling end of the armature.

Abstract: The polarized, electromagnetic relay includes a magnet frame, relative to conduit rabbets, with angles-off yoke arrangement, which includes two separated, parallel-arranged yokes, as well as a permanent magnet that lies therebetween and between anchor plates. The two yokes are L-shaped and formed exactly identical, whereby their core shanks stretch over the entire length of the exciter coil, and lie next to each other in the region of the exciter coil. Thereby a mechanically and electrically absolutely symmetrical magnet frame results, whose asymmetry is compensated by losses arising from the air gap. Through the use of individual yokes there ensues a simple assembly in the spring jack, which functions as holding element for all of the parts.

Abstract: The electromagnetic relay is constructed as a monostable or as a bistable relay with a rotatable tumbler switch. In both forms, there is a switch spring, that is adapted to the anchor, resolvably fastened in the anchor. Thereby an improved mass moment of inertia results, as well as improved switch stop of the relay, and an improved shock and vibration resistance. The switch spring has a sprayed-on synthetic footpiece which is fastened resolvably, turnably and pushably in an adapted opening of the anchor.

Abstract: An electromagnetic relay especially such a relay with a spring jack, that serves for holding the magnet coil and the contact spring jump. In the simplest form of the relay, it includes the feature that the individual contact springs of the contact spring jump are provided with one piece fitted flat plugs, which are positioned in grooves in the ground wall of the spring jack, and in such position are securely fixed from the standpoint of strength and form.
