Abstract: A continuously variable speed transmission comprises a continuously variable speed change mechanism, a ratio control actuator, a controller controlling operational direction and speed of the ratio control actuator, and a speed reduction ratio detection sensor. The controller, in the case of outputting a command to reverse the operational direction of the ratio control actuator, keeps the ratio control actuators actuating at a maximum actuation speed in the reverse operation direction, until the speed reduction ratio detection sensor detects a fact that the speed reduction ratio of the mechanism has changed into the reversed direction after output of the command.

Abstract: To gain access to the cutting edge of a saw tooth in the direction of both the back and the front face of a tooth in a single grinding process, the grinding tools (27,37) are adjustable in relation to both their respective pivoted arms (2,3) and with them relative to the machine frame (11,12). Only the primary pivoted arm (2) is driven up and down by a drive (43), pivoting the secondary arm (3) with it by a drive joint (6). Because the pivot axes of pivoted arms (2,3) are not parallel, a universal coupling (6) must be used. This drive joint (6) is offset relative to the pivot axles (32) upwardly from the saw-blade guide (13) in the plane (14) of the saw-blade. Thereby with an otherwise identical device wide or larger-diameter saw blades can be ground.

Abstract: A theft-resistant fastener system includes a rotatable wrench adapted to engage a head portion of a fastener and to rotate that fastener and head portion about a fastener axis. The wrench and fastener jointly have at least three ball-and-socket joints distributed about the fastener axis. Each of these ball-and-socket joints has a ball in the wrench and a socket in the head portion of the fastener, with each socket being provided with a circular cross-section about a socket axis extending at an acute angle to the fastener axis. The wrench has a releasable actuator for pressing the balls into the sockets preparatory to and during rotation of the wrench about the fastener axis. The head portion of the fastener is prevented from clearing the balls, when the actuator presses these balls into the sockets, by providing that head portion at each socket with an overhang extending over part of the ball in that socket.

Abstract: Hydraulic tongs, used to screw oilfield tubulars together, are equipped with torque control means which enable the tongs to rotate the tubulars and then gradually apply torque until a preselected torque value is reached, hold the torque at this value a desired period of time and then release the torque. In one form of the invention, a tong control restricts the power of the tong motor to enable low torque rotation while limiting the maximum torque which can be produced by the tong motor. A hydraulic cylinder placed in the tongs' restraining line is controlled to shorten, hold or extend the line. When the line is shortened, the tongs are pulled in a direction which increases the torque to a value above the maximum torque produced by the tong motor. The system allows heavy, powerful tongs to be used to accurately apply and hold a wide variety of selected torque values.

Abstract: A projectile is initially accelerated to a supersonic velocity and then injected into a launch tube filled with a gaseous propellant. The projectile outer surface and launch tube inner surface form a ramjet having a diffuser, a combustion chamber and a nozzle. A catalytic coated flame holder projecting from the projectile ignites the gaseous propellant in the combustion chamber thereby accelerating the projectile in a subsonic combustion mode zone. The projectile then enters an overdriven detonation wave launch tube zone wherein further projectile acceleration is achieved by a formed, controlled overdriven detonation wave capable of igniting the gaseous propellant in the combustion chamber. Ultrahigh velocity projectile accelerations are achieved in a launch tube layered detonation zone having an inner sleeve filled with hydrogen gas.

Abstract: A uniflow engine has a plurality of cylinders disposed symmetrically around a common crankshaft connected to pistons reciprocating in the cylinders. In response to the availability of a working fluid vapor at a predetermined condition, such as a high pressure or temperature, incoming vapor is supplied to those cylinders in which the respective pistons are in their working strokes to thereby initiate rotation of the crankshaft in a predetermined direction regardless of the position in which the crankshaft had stopped last. Once rotation is initiated and a predetermined mode change speed attained in a "start-up mode" by engine operation from start, vapor inlet valves are controlled to change engine operation over to a "running mode". In the "start-up mode" incoming vapor is admitted over a substantial portion of the piston working stroke, whereas in the "running mode" vapor inflow is terminated relatively early in the working stroke so that a vapor change does work in expandiing against the piston.

Abstract: An apparatus and process for forming a center-filled confectionary rope in which the center candy is a candy which, during the forming process, is too viscous to be pumped. A center candy is obtained and formed into a continuous cylindrical shape. This is done by using a feeding miller which extracts from the viscous center candy mass a continuous flow of candy. This continuous flow of candy is introduced into a batch roller which forms the continuous flow of candy into a continuous cylindrical shape. An exterior candy mass is obtained and formed into a continuous rectangular shape. This is accomplished by placing the exterior candy mass in a feeding miller which extracts a continuous flow of the exterior candy mass in the form of a rectangular cross section. The continuous rectangularly shaped exterior candy mass is then attached to the continuous cylindrically shaped viscous candy mass and wrapped around the cylindrical center candy in a helical fashion.

Abstract: An after-firing safety device in a projectile with percussion fuze includes a spiral spring set having at least three springs wound up in series with respectively opposite directions. The spring set, maintained under tension by a cage, starts to uncoil as soon as the cage slides off the spiral spring set on account of the acceleration of the projectile during firing. The time elapsing until a central aperture has been entirely vacated depends on the number of springs, the spring lengh, the spring tension, and the friction characteristic. The after-firing safety device is equally well suited for spinning projectiles as well as nonspinning projectiles.
