Abstract: 34 YO-YO* WITH TWIST-RESISTANT SUPPORT A toy capable of combined rotational and translational motion. Two parallel discs are connected through their centers by a single axle. The axle is suspended from a support connected at a position between the two discs. Said support is of a twistresistant type, offering a greater torsional resistance to twisting about the axis of the string than conventional yo-yo strings. The support may be anchored to the axle in a non-sleeping mode, or it may be looped around the axle allowing the yo-yo to sleep. In order to operate the toy, the end of the support opposite that which is connected to the yo-yo axle is held by the user, and an up-and-down gentle motion is imparted to the toy. The end of the support may be connected to a swivel system which is in turn connected to a ring for holding the toy. Particular types of supports for the present invention include a tape or ribbon.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention is for an induction meter having a voltage  and a current magnetic section,  each producing magnetic flux for rotating an electroconductive disk  at  a rate  responsive  to the magnetic  flux.  The voltage magnetic section is comprised of a substantially E-shaped  lamainated  magnetic  core having a center  leg terminating at a main pole face and two  adjacent  legs terminating at coplanar auxiliary pole faces on opposite sides of the main pole face.  The first and last laminae of the core define a first and a second side,  respec-tively, of the core.  A voltage coil is wound about the center leg.  A first voltage shunting member is located in magnetic proximity to  the  first  side  of  the  core. A spacer bracket is located between the first side of the magnetic core and the first voltage shunting member.  The spacer bracket carries a self-aligned, light load adjust-ment assembly having a movable tab extending over portions of one of the auxiliary pole faces and the main pole face thereby providing an adjustable magnetic flux shunt path. A second voltage shunting member is located in magnetic proximity to the first side of the core and spaced from the first voltage shunting member by a nonmagnetic spacer. The second voltage shunting member has a  fixed tab  in magnetic proximity to the other auxiliary pole face and a fixed tab in magnetic proximity to the movable tab.  In this manner, the first voltage shunting member, the second voltage shunting member and the movable tab all provide magnetic flux shunt paths.

Abstract: COUPLING FOR LINED PIPE            ABSTRACT OF THE DISCLOSURE            Disclosed are coupling joints for interconnecting the ends of metal conduit sections having plastic liners to form a continuously lined conduit and methods for making such joints.          The opposed open ends of lined pipe are fitted with flanged end face collars which cover the end faces of the pipe and the open ends are then joined in an abutting relationship within a coupling sleeve by interference fit coupling.  The coupling sleeve carries an internal sealing band which mates with the outer edges of the opposed collars to fully seal the joint and the ends of the coupling sleeve are radially crimped into a corresponding groove in the pipe to mechanically interlock the joint.  Fully lined couplings are also formed by fitting an end face collar in the pin end of one lined conduit and interference fitting the pin end into an unlined bell on a lined conduit.

Abstract: RJP.OO9 Abstract:            Process control instrument using a pneumatically driven resonant element A process control instrument, in which the resonant frequency of a vibrating string varies in accordance with changes in a process parameter being monitored, employs a pneumatic drive system to induce the string into oscillation.   Pressurized gas is discharged through a port, such as a jet nozzle, which is disposed to allow the gas to impinge on the outer surface of the string.  Variations in the alignment between the gas discharge  port  and the  string  permits  different  modes  of vibration, one of which is particularly suitable for process measurement  purposes.   In  a  particular  embodiment  of  the apparatus, an optical sensor detects the frequency of vibra-tions, resulting in an intrinsically safe instrument for use in explosive environments.

Abstract: ABSTRACT OF THE DISCLOSURE           A connector for medical tubing comprises two interengaging parts.  As one part is rotated relative to the other, screw-threads cause a tapered projection to mate with a flared bore to provide a fluid-tight seal.  Further relative rotation causes the outer bevelled edge of the outer wall of one of the parts to move further forward to sealingly engage the sloping wall of the other part.  The projection and outer wall are connected by a flexible membrane to permit this further forward movement.  The connector is particularly suited for use in continuous ambulatory peritoneal dialysis.
