Abstract: The invention concerns a method and a device for attenuating oscillating movements and clamping in a predetermined position one end of a freely depending spoke for example when mounting spoke wheels. The free end of the spoke is permitted to slide into a slot which includes an energy attenuating structure which the spoke passes. When the free end of the spoke thereupon exits from the slot it is intercepted by a magnet and thereafter guided to a securing device by which it is clamped.

Abstract: A body having parallel, flat ends and a through bore of a conical configuration is placed with the small end of the conical bore against and in alignment with a socket. The bushing, having an elastomer on its exterior, is placed with its end in the upper end of the body bore. A bolt head abuts the end of the bushing. The bolt passes through the bushing, the body and the socket. When a nut threaded on the bolt is turned, the bushing is pulled through the body and is subjected to tension and elongation. This reduces the diameter of the elastomeric part of the bushing to fit into the socket. The parts effecting the tensioning are then removed from the socket and bushing. The bushed socket can be placed into service.

Abstract: The body of a cabinet for storing temperature-sensitive articles such as magnetic discs and tapes is built by a process which involves the successive steps of (i) fabricating an internal skin; (ii) attaching so-called "phase-change" material to the skin; (iii) applying insulative polyurethane foam in-situ to the structure of step (ii); (iv) casting concrete or the like water-bearing material around the structure of step (iii); and (v) completing the outer finishing skin. Thus the conventional "double-box" structure is avoided. The door for the cabinet can be built by a similar sequence in which "phase-change" material, insulative form and water-bearing layers are applied successively to a pan forming the internal face of the door.

Abstract: A measuring device for long-term installation in a bore in a rock formation or detecting gradual changes in bore diameter, especially gradual constriction which might affect the condition of radioactive waste deposited in the bore, utilizes telescoping parts under outward spring pressure. One of the two elements of the transducer which by the relative displacement of these elements measures changes in diameter, is a rod held in a friction mounting on one of the telescoping parts that maintains the position of the device in the bore. The other element of the transducer is fixed on the other telescoping part which also carries limit stops (7,8) which in corporation with a stop (6) on the rod confines the lengthwise movement of the rod to a stroke equal to the maximum measuring range of the transducer. For measuring gradual constriction, the transducer is automatically set to begin with the maximum measureable diameter.

On its surface visible through the top reading window, the measuring indicia are offset from the outer end thereof and includes a longitudinally extending central band of a color distinct from the background and directional pointers spaced along the length of the band of a color distinct from that of the band. The pointers indicate the direction of increasing numbers so that a user may readily determine the length represented by graduations intermediate the numbers.

Abstract: There is disclosed in the present application, a gage particularly adapted to measuring the effective interior diameter of a workpiece or part which is too flexible to be measured at separated points of its internal diameter. Such parts, which may be of metal or plastic, include thin walled containers, the skins of cylindrical drums or shields and similar articles which have interior diameters designed to be closely fitted to rigid frames at assembly. The present gage is formed to restrain the part against distortion by forces incident to measuring, which would otherwise cause the part to become narrower in the direction perpendicular to that of the measuring force and would be the source of substantial error in gaging the effective interior dimension of the undistorted part for purposes of assembly. In addition, the present gage includes a provision for automatically translating the circumference measurement of the part into the effective diameter of the part in undistorted condition.

The system permits successive measurements of camber and of toe to be used to determine ball joint wear in the vertical and horizontal planes.

Abstract: A bubble level has at least two position sensing devices, such as mercury switches, disposed at right angles to each other and connected in a circuit having a three-position switch and an audio indicator, such as a buzzer. When the level is to be used to determine horizontal alignment, these switches move to a first position causing a horizontally disposed one of the position sensors to be cut into the circuit, while simultaneously cutting out the other position sensor. When the level is horizontally aligned, which may be in a position not in full view of the user, the position sensor completes the circuit and causes the audio indicator to sound. When the level is to be used to determine vertical alignment, the switch is moved to a second position, which cuts out the horizontal position sensor and cuts in the vertical position sensor and the same procedure can be undertaken. The switch has a central off position.
