Abstract: ABSTRACT OF THE DISCLOSURE A composite structural member such as an electric transmission or distribution pole, having a thin-walled metal casing, a core of non-metallic settable rigid material such as concrete, and reinforcing members embedded in the core, and method of constructing the structural member are disclosed.  The reinforcing members extend between the ends of the casing and communicate with the case.  They are pre-stressed prior to the pouring of the concrete into the casing whereby the applied pre-stress is transmitted to the casing.  The reinforcing members are secured to the casing such that the applied pre-stress remains permanently on the casing only.  The method of forming the structural member includes securing one of the ends of the reinforcing members to one end of this casing and applying a predetermined stress to the reinforcing members, securing the other ends of the reinforcing members to the other end of the casing, pouring concrete into the casing, and allowing the concrete to set whereby the stress transmitted to the casing remains permanently on the casing only and is not transmitted to the core.

Abstract: ABSTRACT     A workbench includes a top structure and a supporting structure for supporting the top structure above the floor. The top structure includes a three part vice, one part being a first elongate vice member and the second and third parts together forming a second elongate vice member extending in side-by-side relationship with the first elongate vice member, the two elon-gate vice members having opposed clamping faces.  A first vice operating arrangement causes movement of the clamping face of at least one vice member towards and away from the clamping face of the other vice member.  A second vice operating arrangement causes relative movement of the second and third parts in a direction parallel to the direction of elongation of the vice members to permit clamping of objects between opposed further clamping faces of the second and third parts.

Abstract: AXLE FOR MOTOR VEHICLES               Abstract of the Disclosure A drive axle assembly for steerable wheels which is pivotally mounted on the frame of a motor vehicle and has two drive shafts in a single axle housing, the shafts angled with respect to each other so that they form a V-shaped configuration opening down-wardly and rearwardly to increase the distance between the under-side of the axle housing and the ground while maintaining the improved steering capabilities of a swept-back design.  The assembly includes a differential having an output axially aligned with and connected directly to one of the drive shafts.  The differential is driven by a pinion gear connected to a non-articulated shaft which extends from a transmission and is mounted for rotation about an axis corresponding to the pivotal axis of the assembly so that no universal joint is required between the transmission and differential.  The other drive shaft is connected through a universal joint to the differential.

Abstract: ABSTRACT OF THE DISCLOSURE           A tandem quadrupole mass spectrometer system in which an AC-only section is close coupled with a standard AC-DC section with the rods of the two sections closely longitudinally adjacent each other.  The rods of the AC-only section are of open structure, formed by thin wires, to allow gas to be introduced into the system and to escape through the open structure rods.          The system is particularly suited for use with a tandem quadrupole system consisting of three sections, namely an AC-DC section, an AC-only section, and an AC-DC section all close coupled, with a target gas introduced into the AC-only section to induce CID of ions traveling through the system.  In one arrangement the rods of the AC-only section have solid centre portions between which the target gas is introduced, and open structure end portions through which the target gas may flow away so that little of it enters the end AC-DC sections.  In another embodiment, gas is beamed directly through a short open structure section by placing an appropriate gas dynamic beam forming device such as a  collimated hole structure or a gas dynamic free jet on one side and an appropriate vacuum pumping arrangement on the other.

Abstract: ABSTRACT OF DISCLOSURE      The inflatable packer element of the present invention includes an inflatable bladder means having a braided wire reinforcing element.          An end of the reinforcing element is received between a tapered surface of an annular anchor means and a tapered surface of an annular wedge means.  A threaded portion of the anchor means engages a threaded portion of an annular ring.  The wedge means is slidably received within the annular ring and engages an abutment of the ring, so that when the threaded connection between the anchor means and the annular ring is made up the reinforcing element is clamped between the tapered surfaces.  An additional clamping force is then applied by applying liquid epoxy under pressure against the wedge means to further drive it toward the anchor means and increase the clamping force on the reinforcing element.  The pressure is main-tained until the epoxy is hardened.  The joint is then further strengthened by forcing additional liquid epoxy into the area between the reinforcing element and the tapered surface of the anchor means to bond the reinforcing element to the anchor means.

Abstract: CONTACT PRINTING APPARATUS AND METHOD      Abstract of the Disclosure Apparatus and method are disclosed for contact printing information from a master record carrier onto a replicate material of a type that emits gas during the con-tact print exposure (e.g., a diazo-film emulsion).  It has been discovered that the emitted gas acts as an efficient lubricant of the master-replicate interface and contributes to relative movement between the master record carrier and the replicate material during the contact print exposure.  In the case of videodisc replication, wherein video information is recorded in the form of billions of micron-sized apertures, such relative movement severely degrades the replicated imagery.  To limit such relative movement, a preferred em-bodiment of the present invention provides contact printing apparatus, including a specially filtered exposing source, that substantially eliminates relative movement between the master record carrier and the replicate material.
