    Abstract: An actuator includes a housing and a stationary, annular magnet coil to which a reversible direct current can be supplied. A displacement member which partially surrounds the magnet coil is mounted within the housing so as to be linearly moveable. A first pair of permanent magnets is mounted in the displacement member so as to cover a portion of the coil, wherein the north pole is located above the coil and the south pole is located below the coil. A second pair of permanent magnets is also mounted in the displacement member so as to cover a portion of the magnet coil. The second pair of permanent magnets is arranged diametrically opposite the first pair relative to the magnet coil and the south pole of the second pair is arranged above the magnet coil and the north pole below the magnet coil. Thus, when the magnet coil is excited, the displacement member linearly moves within the housing relative to the stationary coil. At least one connecting piece is attached to the displacement member so as to extend out of the housing.

    Abstract: An extruder head for producing profiles of rubber and/or plastic mixtures has a stationay main part which has a forward face in which the discharge ends of at least two extruders, rigid with the stationary main part open. The stationary main part has a transverse pivot shaft at one side of the forward face and, at the side opposite the pivot shaft, an abutment which projects forwardly of the forward face. A movable main part is pivoted, with play, on the pivot shaft and is swingable between a closed position in which it overlies the forward face and an open position. An extrusion die unit is disposed between the outboard end of the movable main part and the abutment. Flow channels between the movable main part and the stationary main part lead from the extruders to the extrusion die unit. Hydraulically operated clamps hold the movable main part in closed position and a hydraulic servo motor exerts on the movable main part a force parallel to the forward face of the stationary main part and directed toward the abutment. In one embodiment, there are two movable main parts pivoted at opposite sides of the stationary main part and having an extrusion die unit between them.

    Abstract: The generation of tape tension, based on the capacity for elastic flow of elastomeric incompressible layers, in a tape transport apparatus employing at least one capstan in contact with supply and take-up reels of tape is accomplished by producing a higher compressive force at the point of contact between the take-up reel and the resiliently deformable peripheral portion of the capstan than at the point of contact between the supply reel and the capstan. The difference in compressive forces is brought about by an additional force which is produced by means of a drivable rotating body and is transmitted to the tape reel carriers by means of a cable which is guided over this rotating body.

    Abstract: A monorail system having a rail surface that is provided for small vehicles traversing an incline or slippery areas, with the surface having a plurality of spaced recesses positioned in those areas to form gripping edges for the drive wheels of the vehicles. The recesses may be of a variety of shapes and positioned in different ways to provide the proper grip. The recesses may be mechanically punched into a separate elongated flat bed riveted in appropriate locations to the rail. The punching may be done in such a way so as to form raised ramp-like edges adjacent the recesses to help with the gripping action. The ramp faces face downwardly in inclined areas. The drive wheels of cooperating vehicles may have elastic treads to help with the gripping action.

    Abstract: A dual braking system is provided for high speed sleds in which the center of gravity of the operator is placed between fore and aft brake shoes, which are operated simultaneously by the operator without the need for shifting positions. Thus, the brake system is effective even though the operator is naturally shifted forward by the braking action. Also included in the brake system is a wheel assembly, which may be operated by the single brake lever to accommodate fast acceleration. Operating the brake lever to shift the wheel assembly into effective operative shifts the center of gravity of the operator over the wheel assembly. The dual brake shoes pivot around horizontal axes and are disposed adjacent the longitudinal centerline of the sled to avoid lateral deflection of the sled when the brakes are applied.

    Abstract: Method of providing position, e.g. attitude control for space vehicles having control thrusters producing thrust for imparting momentum upon the vehicle, further having a control apparatus for the thrusters causing them to produce thrust bursts or pulses so that controlled, incremental momenta be imparted upon the vehicle, such thrust bursts being triggered respectively when the vehicle tends to move beyond selected descrete deviations and error position levels. The highest level, one in either direction, define a range of positional tolerance, and the thrusters are operated, so that a relatively small momentum is produced when the vehicle tends to move past either of said maximum levels; the thrusters are operated on the other levels under these conditions. The momentum produced on any such level is smaller than the sum of momenta to be produced on all higher position levels; such corrective momentum is produced only after momenta have been produced for all selected smaller position levels; and each level (except the highest) is used only for each sequence of thrust bursts leading to a residual error cycle wherein the vehicle is caused to oscillate within the range of tolerance with reversal occuring on each range limit.
