Filed: 1994-06-30
Abstract: ABSTRACT          A slider puzzle with a plurality of slide members is provided. Each slide member intersects with at least one other slide member at an intersection point and is moveable between two end positions or any number of positions in between. Each slide member is also provided with a gating means selectively located at each  intersection  point  in  accordance  with  a  pre-determined sequence or sequences of moves.

IPC: H03M7/36
Filed: 1994-08-24
Abstract: A novel method and apparatus for use in digital video compression provides improved block-based motion compensation using the global motion of a video frame.  A video frame comprising a plurality of blocks may be compressed for transmission using block motion vectors. Motion vectors are generated by block matching a block to be coded with a block within a reference frame and determining the displacement therebetween.  To effect block matching, motion compensation techniques define a search window within one or more reference frames within which a displaced block will be found.  According to the present invention, the location of the search window within a reference frame is defined using the global motion of the frame.

Title: Earthquake-resistant architectural system
Inventor: CUNNINGHAM JOHN
IPC: F16M13/00
Filed: 1993-03-17
Abstract: An earthquake-resistant architectural system incorporates a number of homeostatic devices which offer increasing, instead of decreasing, resistance to a load and its resulting stresses. A common feature of the improvement is that support posts (144) are topped by bearings (146) facing each other and having grooved channels (143) which are inclined at an angle to the longitudinal axis of each resilient transverse member (118) at rest, so that a horizontal distance, when measured in a straight line between opposite points of contact in the grooved channels (143), decreases as the load increases and bends each resilient transverse member.

Inventor: KRIKORIAN KAPRIEL V
IPC: G01R29/10
Filed: 1994-10-25
Abstract: A processing method that processes interferometer data to provide for rejection of multipath signal returns from an emitter and computes an improved estimate of the relative angle between the emitter and an interferometer. The present processing method comprises the following steps. Interferometric data is gathered that comprises complex signal amplitudes derived from the emitter at a plurality of emitter angles relative to the interferometer. The complex signal amplitudes derived at each of the plurality of emitter angles are processed by maximizing a predetermined log likelihood function corresponding to a natural logarithm of a predetermined probability density function at each of the plurality of emitter angles to produce a plurality of maximized log likelihood functions. The improved estimate of relative angle between the emitter and the interferometer is made by selecting the emitter angle corresponding to an optimally maximized log likelihood function. The present method rejects multipath signal returns from an emitter and computes an improved estimate of the angle between the emitter and the interferometer. The present processing method may be employed to reject radome reflections in radars, particularly those employing antennas having a relatively low radar cross-section.

Title: Hose coupling for compressed air
Inventor: ENGDAHL BJOERN
IPC: F16L37/42
Filed: 1993-10-14
Abstract: The invention refers to a hose coupling for compressed air, which has a safety locking device. The safety locking consists in that when the male member (1) is disconnected, the male member (1) is not entirely disengaged but is caught by the locking balls (4) in the female member (2) until the overpressure in the hose and the tool has disappeared. Then the male member (1) is re-leased. In this way the unpleasant bang that otherwise arises, and the effect that the hose together with the male member (1) moves backwards with enormous power, are prevented in a controlled way.

Filed: 1995-06-30
Abstract: An above-ground secondary containment unit for storage tanks is comprised of a rigid base and upwardly extending side and end walls.  Side cover shields are mounted to the top of the side walls by way of hinges and are intended to contact a side surface of the storage tank thus minimizing or preventing the entry of precipitation or debris into the unit while the tank is in place.  End cover shields are mounted to the top of the end walls using a nut and bolt arrangement and slots in the shield allowing for lateral adjustment of the shields with respect to an end surface of tanks of varying sizes and configurations.  These shields similarly minimize or prevent the entry of precipitation and debris into the unit.  The walls of the unit are tapered so that one unit may be nested within another similarly shaped unit for convenient storage and to permit shipment of multiple units at the same time.  Linear tie-down straps are mounted to one side wall and extend across the top of the unit to the other side wall in order to secure a tank in place.  The whole unit may be mounted on skids to allow transport either alone, or in combination with a tank secured by the tie-down straps.
