Abstract: PENDANT CONNECTOR                   ABSTRACT OF THE DISCLOSURE         A device for removably attaching a pendant to a decorative chain is disclosed.  The device comprises two arcuate latching elements.  The first latching element receives the chain and has an arm swivably attached to one end, which engages the other end when it is swiveled to a closed position, thereby creating a closed, locked loop around the chain.  The second latching element receives a connecting loop on the pendant to be attached to the chain. The second element has a locking bar swivably attached adjacent to an eyelet on one end.  The eyelet is adapted for receiving the first latching element.  The locking bar has a longitudinal opening through which the eyelet protrudes when the locking bar is swiveled to a closed position, the locking bar thereby creating a closed, locked loop around the connecting loop on the pendant.  When the two elements are interlocked in this manner, they are oriented at right angles to each other. The device of the present invention allows the attachment of substantially flat pendants to chains so that the front face of the pendant can be seen.

Title: Lidar Scanning System
Inventor: CAMERON EVAN S
IPC: G01S7/481
Filed: 1991-03-22
Abstract: A LIDAR scanning system having a rotating multifaceted polygon mirror for transmitting modulated light from one of its facets to a surface. Diffuse light reflected off said surface is received by another facet of the polygon mirror and reflected to a photo detector.  The phase difference between the transmitted and received light is then used to compute the range of the surface from the scanning system.  The intensity of the returned light is used to create a gray scale image of the surface.  The use of separate optical paths fro the transmitted and returned light, and a small scanned field of view results in an improved signal-to-noise ratio.

Abstract: A footboard of a skateboard is with respect to a respective reference plane which at riding straight (= x plane) is parallel to the riding path (= the ground), and at turning (= x'' plane) is with respect to the direction of riding slanted to one or the other side, is rhythmically swung around a longitudinal axis (O) of swinging lying in suspensions (4, 5) of the skateboard. The amplitude (A) and the frequency of swinging are mutually coordinated in a manner that swinging does not result in such meandering of the skateboard, which was felt inconvenient. To a socket shaft housing (8) of a suspension (4, 5) of the skateboard, said housing encasing a roller shaft (11), there is to each end thereof attached a gearing (9, 10), the gearings designed mirror-symmetrically. The gearing (9, 10) is composed of an essentially three-part housing assembly, which comprises a mounting casing (13), an upright intermediate wall (16) and a mounting cover (17), as well as of a train-type gearing composed of a toothed rack (19) as a driving constituent and a gear (25) bound to the roller shaft (11), as a driven constituent.

Title: Hydrostatically balanced pump
Inventor: SPELLER DAVID J
IPC: F04B47/06
Filed: 1992-05-01
Abstract: ABSTRACT OF THE DISCLOSURE         An improved device for lifting liquids up a pipe, particularly a long pipe, in which the weight of the column being lifted is used as part of the force driving one part of the cycle of the pump lifting the liquid. In one example the pump is driven in part of its cycle by a column of a second working liquid, compressed at the surface in a pulsed cycle. In the other part of the two-step cycle, the weight of the produced column is applied into the pump linkage to move the working liquid column in reverse direction and thereby stoke the pump.  This cycle continues indefinitely, and the energy supplied is independent of depth, which is a major improvement over existing designs. The device will work equally-well with flexible pipe in non-vertical situations.
