Abstract: An actuator, comprising an actuation member positionable into a first retracted position and a second extended position, and a retaining member structured to maintain the actuation member in the first retracted position, and to selectively release the actuation member from the first retracted position in response to an extension force.

Abstract: A thermoforming trim press has one or more connecting arms for driving a movable platen, each arm having a pivotal connection between two adjacent sections of each connecting arm which is normally locked during normal press operation whereby the movable platen is able to move further back from a normal retracted position to increase the available clearance when changing or maintaining tools mounted on the movable platen. The pivoting ability of the connecting arm sections also simplifies adjusting the stroke of the press. A counterweight may be driven by the crank pins to match the press stroke adjustments and to thereby correspond the movement of the counterweight to the movement of the movable platen.

Abstract: Systems and methods and methods relating to the control and operation of an impactable vehicle restraint. The impactable vehicle restraint has a vertically movable barrier. The impactable vehicle restraint has a control system having three switch signal inputs that is compatible with two switch input systems. The impactable vehicle restraint has a control system to stop the motion of its drive system for the based on either sensing that the restraining device is at its limits of motion or that the drive system has been activated for a predetermined amount of time, whichever occurs first.

Abstract: A suspension actuator (1) for positioning a movably mounted component of a motor vehicle suspension, including a first actuator component (4), which is to be connected to the movably mounted component, and a second actuator component (3), which is to be connected to a fixed suspension component, wherein both actuator components can be axially adjusted relative to one another via a ball-type linear drive (5), which includes a threaded spindle (6) and a nut (7) running thereon. Either the nut can be driven via a drive motor (10) for the axial adjustment of the threaded spindle or the spindle can be driven via a drive motor for axial adjustment of the nut.

Abstract: A press has a slide which can be driven by way of one or more one knee link element by a driving device in order to carry out a stroke movement. The knee link element or elements is or are connected by at least one connection element with another knee link element which is also mounted on the slide.

Abstract: An anti-overloading device for use in a restraint-camming apparatus in which the apparatus includes a linear guide for guiding an associated operating member in reciprocating movement and a restraint cam for reciprocating the operating member in its movement has a toggle assembly that which is fixed to the operating member. The toggle assembly comprises a “U”-shaped body, two support links that are rotatably connected to the free ends of opposite free ends of the toggle assembly body portion that engages the ends of the links, and a cam follower rotatably supported by the pin. The cam follower is engaged with the restraint cam to thereby put the restraint cam in a controlled restraint position between the cam follower and a counterpart cam follower roll that is fixed to the operating member. The toggle assembly permits the anti-loading structure can be reduced in size, still permitting the setting of an increased permissible load.

Abstract: A Halloween toy comprises an image member received within a frame. A mechanism is provided for moving the member into and out of the frame so as to achieve a scary effect. The image member may represent a face and movement of the member may be accompanied by light and sound effects. The image member may be covered by a sheet of material such that it is not readily visible when received within the frame but becomes visible when it it projects out of the frame. The mechanism for moving the image member is designed so as to occupy only a minimum of space.

Abstract: Rectilinear vertical reciprocating movement is transmitted to the needle-holder beam of a needling machine by a crank mechanism preferably comprised of two horizontal auxiliary connecting rods hinged to a support of the beam. The two auxiliary connecting rods are mounted to the two sides of the needle-holder beam and support. Each auxiliary rod includes an end hinged to a related main connecting rod, with the other end being joined to the structure of the machine by a sliding block and two conjugate profiles. One of the profiles is fixed and the other profile is mobile. The profiles form a rolling coupling, so that each sliding block that is hinged to the related ancillary connecting rod slides when the crank mechanism runs between two extreme axial positions.

Abstract: A power transmission device for a press machine comprises a connection link connected to a crankshaft of the press machine and reciprocated in accordance with the rotation of the crankshaft, a first slider provided in a frame of the press machine so as to be reciprocated in a first direction, and pivotally connected to the connection link, a first link mechanism provided with a pair of first links pivotally connected to each other, wherein one of the first links is pivotally connected to either the connection link or the first slider so as to be folded and extended while following up the reciprocating movement of the connection link, a second slider provided in the frame displaceably in the first direction and pivotally connected to the other first link, and a mechanism for adjusting the position of the second slider in the first direction, whereby the bottom dead center position and the stroke length of a slide can be adjusted by a common mechanism.

Abstract: A force impulse generator designed for machines with impulse action used for press working of metals, ceramics, cermet and other materials can produce force impulses with high values and large amplitude of displacement of the impulse body with reduced overall size, high efficiency, increased service life and neutralized side forces. The generator includes a stationary base to which there is movably connected by means of columns a box shaped impulse body. In a cavity formed between the base and body, there are disposed two identical crank mechanisms, each of which has a bottom hinge segment, a bottom segment arm, a middle hinge segment, a top segment arm and a top hinge segment. The middle hinge segments are driven by connecting rods connected to a common crankshaft. As a result the impulse body is displaced reciprocally and produces an impulse of force.

Abstract: An acceleration control device for a hydraulic drive unit having a rotatable control shaft movable between an on position and an off position. An arm is connected to the control shaft for rotating the shaft between the off and on positions. A motive apparatus is movable between a first position which corresponds to the off position of the control shaft and a second position which corresponds to the on position of the control shaft. A mechanical linkage is connected between the motive apparatus and the arm. The linkage imparts movement to the arm in response to movement of the motive apparatus to cause the control shaft to move between the off and on positions as the motive apparatus moves between the first and second positions, respectively. The linkage is configured to provide a substantially nonlinear relationship between the speed of the arm and the speed of the motive apparatus.

Abstract: An arrangement for an intermittent operation in a notching machine which includes a ram driven by way of a crank or eccentric drive which ram is articulated to a toggle joint. The notching machine has an operating cycle which consists of alternatingly successive notching and notch-free steps which is attainable by means of a cylinder-piston unit activatable pneumatically or hydraulically which unit is in operative connection with an eccentric supported on a pin with the eccentric being the central fulcrum of the toggle joint. A second toggle joint with a counterbalancing mass is diametrically opposed to the ram with the second toggle joint being articulated to the eccentric. The central pivot as well as the points of articulation of the toggle joints to the ram and counterbalancing mass are disposed substantially in one plane.
