An amusement device comprising a guide construction forming a track, along which a vehicle, in which at least one person can be seated, is movable in a direction of transport. A holder of the vehicle, which accommodates said person, can be tilted about a tilting axis from a first position, in which the person present in the vehicle includes an angle with the track, to a second position, in which the person who is present in the vehicle in use extends substantially parallel to the track, and vice...

A flaw penetrant test panel having a sheet metal surface in which are impressed tiny or microscopic flaw simulating cavities distributed over the test surface to receive one or more penetrants being tested, the mouth size of the cavities being in the range of about 1 to 10 thousandth inch and being formed by heating the metal to incipient softening temperature followed by penetration of the surface test area using a needle-like tool proportioned to the desired cavity size and depth and which upo...

A semiconductor memory device including a substrate having one conductivity type; read only memory element formed in the substrate for storing fixed information, the element having a control gate, a floating gate, a source region, and a drain region, both of the regions having an opposite conductivity type to that of the substrate; a first region having the above one conductivity type which surrounds the element; a light shield layer, connected to the source region and the first region, for cove...

A test panel which may be used for evaluating inspection penetrant crack detection performance, comprising essentially a soft, malleable metal substrate coated with a brittle surface layer of controlled thickness within the range of from about 5 microns to 50 microns, said brittle layer having a pattern of craze cracks which are generated by a mechanical stretching of the panel to a point where the average crack width falls within the range of values from about 0.5 micron to 20 microns.

A towing system in which a moving traction means has pickup means thereon movable into engagement with one end of an elongated element, such element being capable of transmitting tension forces but being incapable of transmitting compressive forces and having a body attached to its other end. Such element is maintained taut preparatory to and during the instant of initial connection between the traction means and elongated element so as to extend tautly at a right angle with respect to direction...

The object of this invention is a launching system for cars running on a track in equipments for amusement parks, such as roller-coasters or the like, including a mechanical launching device where a falling counterweight moves a rope to pull a train of cars with the needed force, and wherein the counterweight is slowly lifted back up at the end of the launch, while the cars complete their track, thus only requiring some low-powered equipment. The system according to the invention is far cheaper ...

A device for the extraction of screwthreaded sires for osteosynthesis, characterized in that it comprises: at least two lever pieces (20, 21) hinged together and having at one longitudinal end (20a, 21a) seats (22, 23) for grasping the end of a wire (19) which it is required to extract, and clamp means acting on the ohter end of said lever pieces (20, 21) to promote their opening in such a way as to generate a couple of gripping forces on the end of the wire (19). Said clamp means are of screw t...

A serial data routing device for use in routing serial data between a computer and a peripheral device. The data routing device includes a computer data converter which communicates data under the USB protocol with a computer and which converts data received from the computer into converted computer data. A peripheral data converter is also included which communicates data under the USB protocol with the peripheral device and which converts data received from the peripheral device into converted...

The invention relates to the entertainment industry. The inventive big dipper comprises a base (1), a closed guidway provided with a spiral part (3) for lifting, a part (4) arranged in the station (5) area, a dead loop part (6) and a transport means. Said transport means turns about the longitudinal axis of the spiral part (3) for lifting until a roll-over is performed prior to landing. Said invention provides passengers with a variety of entertaining effects.

A conveyor device for alignment in which minutely displaceable members and hydraulic fluid supply pads are disposed between a slide and a guide. The relative position of the slide and the guide is adjusted by controlling the dimension of the minutely displaceable members.
