Abstract: A holding member can be made to move up and down with long strokes by means of short vertical strokes so that the overall arrangement can be downsized and lightweight. Additionally, the holding member can be held to a constant attitude and the overall arrangement can be simplified to reduce the cost. A swing arm is adapted to be swung between the metal mold of a resin molding machine and the outside of the resin molding machine by means of a rotary shaft rotating in response to a vertical motion of an elevating body relative to a vertical frame and, at the same time, a fitting member is adapted to be driven to rotate in response to the swinging motion of the swing arm in order to control the attitude of a vertical arm so as to make its axial line aligned with the vertical direction.

Abstract: A drive chain adjustment mechanism for simplifying the tension adjustment work of a drive chain of an all terrain vehicle. The drive chain is wound around a driven sprocket connected to the rear wheels of the vehicle. The mechanism includes a case to which the driven sprocket is coupled; a cam which moves the case in a fore and aft direction with respect to a vehicle body frame; and a bolt which is located rearward of a shaft portion of the driven sprocket, and which attaches the cam and the case to the vehicle body frame. When the case is moved in the fore and aft direction of a vehicle body, the tension of the drive chain is adjusted.

Abstract: There is no surveillance camera system optimum for monitoring an important monitor place by a surveillance camera mainly for crime prevention day and night without humans in attendance, which can automatically monitor the place without humans in attendance and, when something suspicious is found, follow the suspicious without humans in attendance, and accurately monitor the suspicious at high precision. The present invention provides a surveillance camera driving method achieving such a system having the function of obtaining video image signals by two or more surveillance cameras each having a three-dimensional positioning pan tilt head function, organically processing the video information, comparing the processed information with input data of a plane picture or the like or data of pictures of a front view and a side view or the like, and determining whether the processed video signal is the same as the input data or not.

Abstract: A drive arrangement (10) for a shaft (12), such as a shaft for driving a sectional door, roller shutter or the like, is in the form of a module, carried, in use, by the shaft (12) and including a motor (14), a driven wheel (16) fixed for rotation with the shaft (12) and drivable, in use, by the motor (14), and clutch means (18) and operable between the motor (14) and the wheel (16). The module further includes brace means (20) in the form of a limb attachable to a member which is fixed relative to the axis of the shaft (12), to brace the module against turning as the shaft (12) is driven.

Abstract: The electromagnetic propulsion system or E.P.S. is a rocketless propulsion engine known as a spacedrive. It is rocketless in that it does not involve the expulsion of propellent. It achieves this by reusing the propellent over and over again by having it travel in a loop or circle. The propellent is propelled with the use of electromagnets. The entire propulsion system moves in the opposite direction of the accelerated propellent.

Abstract: A mechanical transmission device to provide selective gear speed output from a constant input. A variation gear affixed to an adjustable crank determines output speed of a free floating following gear and connecting rod assembly dependent on the relative orbit size of the variation gear as determined by the crank. The orbit size is adjusted by the angular inclination of the adjustable crank.

Abstract: A drive for a printing machine with a plurality of printing mechanisms has a closed gear train arranged to connect the printing mechanisms with each other, a drive train extending parallel to the gear train and elastically connected with the latter by at least two power input points, a torsion spring arranged to be located in a trunnion of each of the printing cylinders, at a drive side of the latter, a bush arranged to be mounted in the trunnion of each of the printing mechanisms, and an axially displaceable driver arranged in the bush and form-lockingly engaging the torsion spring.

Abstract: An automobile window regulator for lowering and lifting an automobile window comprises an outwardly threaded cylindrical roller meshing with an inner thread of a rigid guide member secured to an automobile door. The roller is rotatably mounted in a movable pad secured to the window glass and embracing the guide member. A flexible control cable is secured to the center of the cylindrical roller and extends along the guide member to a crank or the like for rotation of the roller. By rotating the roller the movable pad coupled thereto is lifted or lowered to thereby lift or lower the window glass secured to the pad.

Abstract: A drive mechanism for a drill provides both rotational drive and axial feed for a drill of substantial diameter such as those used to drill holes for roof bolts in mine shafts. A plurality of sprockets carry two chains of drive links which interlock around the drill shaft with each drive link having depressions which mate with scroll-like projections on the drill shaft. For axial feed, the sprockets are driven from worm drives in separate housings on each side of the chains, the worm drives being driven from gears in a gearbox which are connected through a differential gearset to a hydraulic motor. A second hydraulic motor also drives through the differential gearset to rotate the drill shaft and the entire drive chain assembly. A large diameter face seal serves as the partition between the chain drive assembly and the gearbox.

Abstract: A gear drive used in water well drilling or blast hole drilling to remove overburden in open pit coal mining, not only rotates the drill pipe but also pulls down or pulls out the drill pipe as it rotates. A hydraulic motor within a housing operates a first gear train to rotate an output shaft at varying speeds. A drill pipe is projected through the output shaft. A plurality of feed rollers are mounted on spherical bearings, the outside diameter of the rollers having a concave recess for operative registry with the drill pipe. When the output shaft is rotated, each roller cocks and digs into the feed pipe causing it to rotate with the output shaft. The pull down and pull up section is driven by a hydraulic motor within the housing through a second gear train. The second gear train drives a plurality of third gear trains for individually driving the respective feed rollers.
