Abstract: A dynamic clipper is used in the guidance control circuits of a wire guided vehicle, such as a lift truck, that is guided by a wire laid in floors between storage racks into which an alternating electrical signal is provided to remove the effects of noise pulses. The wire signal is detected by sensor coils carried by the vehicle, and the amplitude of this signal is used as an indication of the distance of the vehicle to the wire. The dynamic clipper includes a first comparator having one input from the sensor coil and the other input from a reference source. All noise signals greater than the reference voltage are removed. The output is then passed to an inverter and then to a second comparator which performs the same function. Thus both the positive and negative going noise pulses greater than the reference are removed from the sensor output signal.

Abstract: In extrusion apparatus for producing a continuous film of thermoplastic material, either as part of an extrusion coating or laminating process or to cast a continuous film, a chill roll which receives the film directly from the extruder is mounted on a wheeled carriage whereon it can be moved lengthwise into and out of operating relation with the other components of the apparatus without requiring lifting thereof or of other parts of the apparatus. The carriage may be proportioned to move directly between the apparatus in which it is to be used and the floor of the mill, or it may be mounted on a separate wheeled cart on which it is transported to and from the extrusion apparatus. Particularly in the latter case, provision is made for both vertical and lateral adjustment of the base structure on which the carriage is supported in its operating relation with the extruder.

Flow rate of the liquid toner from the process tank to the printing station of the printing unit is controlled by a sensor, logic circuitry, and motorized adjustable flow valve and flow meter.

Abstract: A metal insert is provided for use in forming an elastomer-tipped armature to a precise length. The insert is formed as an elongated member with a central hole passing through its length, and an elastomer element is molded within the hole. A circumferential groove is formed in the exterior surface of the insert to create a weakened "hinge" point in the insert wall such that, as mold elements for forming the elastomer element engage opposing ends of the insert, the insert may be compressed longitudinally at the groove to thereby decrease the overall length of the completed armature to within a predetermined tolerance.

Abstract: A guard as disclosed for use with a woodworking tool such as a jointer having a worktable, a cutter head and a guide fence for guiding a workpiece through the jointer. The guard is pivotally mounted to the table and is biased toward the guide fence such that it covers the cutter head when a workpiece is not present. The guard includes a body portion and flexible fingers formed integrally with and extending from the body portion toward the guide fence. The flexible fingers act as a featherboard during a jointing operation and the pivotal movement of the guard may be limited such that the fingers engage a workpiece as it is fed through the jointer to thereby apply a biasing force against the workpiece toward the guide fence. The fingers further act to resist movement of the workpiece in a direction opposite to the feed direction during a kickback situation and thereby provide greater control over the workpiece.

Abstract: A container for liquids comprises a tube at the upper end of which there is a lid consisting of thermoplastics synthetic material without any carrier material and which is injection molded along the top edge of the tube, forming a pouring means with a closure flap. The closure flap is captively articulated on the lid by means of an articulating axis, on the side opposite the tip of the pouring aperture, being adapted to be engaged on the lid in the open condition via an engaging means. In order that the closure flap can be kept open and can nevertheless be pressed down again into as far as possible a clearly defined position in order to reclose the container, the handle is connected via a curved articulating member to the middle portion of the lid. The curved articulating member is preferably provided on the surface of the lid alongside the engaging means.

Abstract: Combustion engines have opposed pistons in one or more cylinders, with the piston motion determined by cams. Ports, for intake and exhaust, are at one end of the cylinder, opened or closed by one piston, with the combustion chamber at the other end, and the engine being well suited to the optional use of a combustion chamber separate from the cylinder and with the communicating passages controlled by the other piston. That arrangement makes the engine particularly suitable for using heavy or unconventional fuels. The cam profile provides for a four-stroke cycle; one piston moves during the intake and exhaust strokes, while the second piston moves for compression and power strokes. Thus the advantages of a four-stroke engine are obtained while retaining the simplicity of a two-stroke engine. The cam profile may be tailored to the burning characteristics of the fuel, as by providing a period of dwell between the end of the compression stroke and the beginning of the power stroke.

Abstract: The invention relates to a screw closure of plastics material for bottles which are under pressure, comprising a cap (1) having a cap end portion (2) and a substantially cylindrical peripheral cap portion (3) with internal screwthread (7), and a circumferentially extending, inwardly projecting bead (5) at the transition between the cap end portion (2) and the peripheral cap portion (3), wherein a sealing disc (9) which is movable relative to the cap bears against the inward side of the cap end portion (2) and the projecting bead (5). In order, in regard to such a pressure-tight closure, to limit the maximum pressure up to which the closure remains pressure-tight, to a value which is noticeably below the pressure at which a bottle explodes, it is proposed in accordance with the invention that the bead has a segment-like interruption.
