Abstract: A plurality of infrared controlled appliances are controlled from a single UHF radio transmitter remote controller. The controller provides a plurality of separate distinct output control signals to an UHF to infrared transponder. The transponder has a UHF receiver, an infrared receiver, and an infrared transmitter. In one mode of operation, the transponder stores a received infrared signal and correlates it with a received UHF signal. In the operational mode, the transponder transmits a stored infrared signal through the infrared transmitter upon receiving a correlated UHF signal.

Abstract: An aerial cableway system for filming subjects in motion over moderate to long distances. An endless cable is tensioned between two support structures in an elongated loop. A cable carriage is suspended from the endless cable and is in contact with both segments of the endless cable at all times. Each segment of the endless cable passes through the cable carriage in opposite directions by wrapping 180.degree. around two drive sheaves for a total cumulative wrap of 360.degree.. Each drive sheave has associated with it a disc brake assembly. The endless cable is driven by a bull wheel mechanism which is located at the base of one of the support structures. As the endless cable is continuously driven the two segments travel in opposite directions. When the disc brakes on one side of the carriage are engaged, the drive sheaves are immobilized on one segment of the endless cable and the carriage is carried along in the direction that the grasped segment of the endless cable is traveling.

Abstract: A method is disclosed for operating a valve needle for plastic processing plants. The needle valve may be controlled by a control valve, which in turn is controlled by a working gas volume in order to prevent formation of internal waviness in injection molded articles even under very high gas pressures and to assure high flexibility in production without refitting delays. During plastic mass injection the valve needle seals tightly. During gas return the valve needle remains open until the gas bubble in the mold cavity is completely emptied.

Abstract: In a process for interconnecting computers and/or computer networks, the occurrence of an interruption in the network system is detected. A redundant connection is activated as a function of said interruption. The redundant connection is inactive in undisturbed operation. The presence of an interruption is detected by determining whether a data signal appears within a predetermined period of time at the connectors of a redundant connective device. Different criteria are provided to interrupt a closed connecting ring generated by the activation of the redundant connecting device when the initial interference in the network system is eliminated.

Abstract: The color correction system will enhance an operator's ability to edit and correct the appearance of a color image. This system is particularly useful in desk-top publishing applications. A reference image with an overall desired visual impression is displayed on a screen. This reference image is known to print in an acceptable fashion and give a desired visual impression. When the image to be corrected is modified in order to approximate the visual impression of a reference picture, then the picture to be corrected should print acceptably.

Abstract: An intermediate amplification process for digital signals with pulse regeneration, determines the phase difference between the receiving timing signal and the local transmission timing signal and alters the phase of the local transmission timing signal as a function of the phase difference. It is particularly advantageous that the receiving timing signal is used as the transmission timing signal as soon as the phase difference becomes essentially zero. It is possible in this manner to minimize both the startup time delay and the packet spacing, as the number of bits to be stored intermediately may be kept low.

Abstract: According to the receiving method for mobile reception has a plurality of individual receiving antennas, also known as diversity receiving method, on the individual antenna output signals an auxiliary modulation is superimposed and the antenna output signals are added to give a summation signal which as amplified selected intermediate-frequency summation signal is then demodulated in relation to amount and frequency or phase, the phase position of an individual signal in relation to the phase position of the summation signal and/or the amplitude contribution of an individual signal to the amplitude of the summation signal thereby being determined. This information is utilized for optimizing the useful signal with a view to optimum interference suppression for example in that the phases and/or amplitudes of the high-frequency individual signals are changed in dependence upon the phase position and/or amplitude contribution determined.

Abstract: A mold closing apparatus and process for use with an injection molding machine are described. The mold is opened and closed by hydraulic pressure. The disclosed apparatus and method relate to the use of an immobile differential piston within a displaceable, double-acting differential piston which moves within an immobile piston cylinder. This arrangement permits the use of smaller diameters to produce the necessary closing force. The immobile differential piston comprises the necessary hydraulic passages for routing hydraulic fluid to the appropriate surfaces for exerting opening and closing forces.The use of a plurality of displaceable, single-acting pistons in parallel with the differential piston further reduces the diameters needed for exerting the closing force. Locating these single-acting pistons within the support column cylinders makes for an even more compact apparatus.

Abstract: A mixing device exhibiting a mixing chamber, feed and recirculation lines for components and for the component mixture. A control piston reciprocates inside the mixing chamber between a recirculation position where the feed and recirculation lines are in fluid communication and a mixing position where the components impinge and mix in the mixing chamber. At least one component has a straight line recirculation path from its feed to return line through a radial slot in the control piston. A bypass line branches off from at least one feed line and opens into the mixing chamber at a mixing input duct in the same radial plane as a mixing input duct for a second component.

Abstract: A plow debris deflector for attachment to plows is disclosed. The plow debris deflector improves trash flow, buries stalks, stems, leaves and other debris without discing and requires low maintenance while providing excellent soil rotation and burying cover crops, trash, litter and other debris eight to ten inches beneath the surface of the soil. The plow debris deflector may include a first vertical portion having a mounting mechanism for mounting the plow debris deflector to a moldboard plow. The mounting mechanism may include a plow connecting slot so the debris deflector may be interchangeably mounted to a variety of plows. A lower portion of the plow debris deflector may be custom designed to complement the shape of the plow to which it is attached. The plow debris deflector includes a second horizontal portion, which may include a curved and twisted plate member for deflecting stalks and stems of various heights.

Abstract: A combination bottle opener and can opener is disclosed. A bottle opening element may be movably connected to a can opening element. The bottle opening element may include a first end having an angled portion and a protrusion that cooperate to define a bottle cap receiving area. The bottle opening element may also include an angled body section. The can opening element may include a cutting blade pivotally connected to a body part. The cutting blade may include a cutting edge, a cut-out portion and a plurality of projections. The body part may include a strengthening rib, a tapered edge and a can rim receiving notch. In an open, extended position the combination opener has length greater than the bottle opening element or can opening element alone. This greater length increases the leverage and decreases the amount of force necessary to open a bottle or can, respectively.

Abstract: A boundary-layer microphone may obtain a frequency independent, hemispherical directional characteristic with a high tonal quality. The geometrical configuration of the mounting plate and the installed location of the membrane within the surface of the mounting plate are chosen so that a flat frequency response is obtained at the installed location of the membrane, i.e., the superposition of the incident primary sound field on the secondary sound field created by diffraction will not cause any deviation from a flat frequency response and a smooth, hemispherical polar pattern. The mounting plate may be triangular. The membrane may be installed in the vicinity of the center of gravity of a scalene triangle.
