Title: Optical recording card having hologram contained therein and method of producing the same
Inventor: FUKUSHIMA YOICHI
IPC: B42D15/10
Filed: 1987-10-13
Granted: 1994-04-12
Abstract: ABSTRACT OF THE DISCLOSURE         The present invention is concerned with a certification card such as an ID card or the like including a hologram and an optical recording portion.  The hologram is such that amplitude and phase of light waves emitted from an object are recorded and an image of the object is rebuilt by emitting light to reproduce the amplitude and phase of the thus emitted light.  On the other hand, the optical recording technique is such that data pits are formed on an optical reflective surface of an optical recording layer and the thus formed data pits are detected by differences in optical reflectivity from the data pits when the object is illuminated by a laser beam so that data are read.  According to the present invention a card is constituted by adhering a card front board to a card rear board, with a hologram and optical recording portion formed between the card front board and the card rear board.  The such prepared certification card is difficult to be falsified and altered and therefore it has high security.

Title: Method and apparatus for locating leaks in a multiple layer geomembrane
Inventor: CONVERSE MERLE E
IPC: G01R31/00
Filed: 1987-11-12
Granted: 1990-11-13
Abstract: ABSTRACT        A leak detection and location method and apparatus for detection of perforations in a obscure geomembrane liner is set forth.   In a typical application, upper and lower liners are positioned contiguous to one another and a conducting liquid is placed between them.   In the event a tear or perforation is formed in the lower liner, a current flow path is established from a power supply and conductors  connected to the power supply.  The current flow path extends through the liquid  to the  leak.    Because  of the  liquid path through the liner, electric  current  will  flow  through  the  perforation  and establish an associated magnetic field in the near vicinity of the leak.   Magnetic sensor means are then swept across the surface of or through the impounded liquid  above the liners to indicate such magnetic field variations and the locations of such perturbations  correspond to the locations of the leak perforations.

Abstract: IMPROVED BENDING MACHINE                ABSTRACT OF THE DISCLOSURE A hand operated rebar bender and bent rebar straightener which includes a base, a pair of spaced apart bending posts and a linearly reciprocal slide disposed between the posts and movable reciprocally in directions perpendicular to a line interconnecting the posts.  The slide defines a first and a second groove, both adapted to receive rebar, which move with the slide. The first groove is positioned so that straight bar to be bent is originally tangent to the peripheries of the posts.  The slide is movable over a distance sufficient to move the first groove past the line interconnecting the posts so that the appropriate bend is formed in the rebar.  The second groove is positioned so that in one of the limiting positions of the slide travel it is relatively further removed in the direction of slide travel from the bending posts than the first groove to permit the insertion of bent rebar therein.  The bent rebar is straightened by moving the slide, and therewith the second groove until the rebar in the second groove is substantially tangent to the peripheries of the bend-ing posts, at which the point the previously bent rebar is straight.

Title: End protector for a reinforcing bar
Inventor: LUNN JOHN E
IPC: E04G21/32
Filed: 1988-10-28
Granted: 1992-06-02
Abstract: ABSTRACT An end protector for a reinforcing bar has a one piece support and a cushion.  The support has a cylindrically-shaped receptacle with two arms extending outwardly therefrom and two longitudinal slots that are generally opposed to one another along either side of the receptacle.  The arms hold the cushion in position on a side of said receptacle opposite to the reinforcing bar.  When an external force is exerted on the cushion, at least part of the force is transferred through said arms to said receptacle, thereby causing the slots to narrow and the receptacle to further tighten onto said rebar. When the external force is removed, the support returns to its initial position. Thus, when no exeternal force is exerted onto the protector, it can be easily installed or removed from an end of the reinforcing bar.

Abstract: FLUID DELIVERY CONTROL AND MONITORING APPARATUS             FOR A MEDICATION INFUSION SYSTEM                 Abstract of the Disclosure A fluid delivery monitoring and control apparatus for use in a medication infusion system is designed for use with a disposable fluid pathway that incorporates a sterile cassette containing pumping elements and sensor interfaces. The apparatus comprises a multi-segment drive mechanism, controller, and monitoring system.  Fluid pumping is accomplished by controlling DC motors in the drive mechanism, each of which is coupled to two valves and a reciprocating piston for an individual pumping channel in the cassette.  The motor is geared down to provide an appropriate maximum speed and torque.  A cam sequentially actuates an inlet valve, piston, and an outlet valve in the cassette.  A range of fluid delivery rates is achieved by periodically sending pulses to the motor.  The output flow rate of the pump is maintained by a digital feedback controller which uses closed-loop feedback control to provide accurate regulation.  At regular time intervals, the controller computes the motor voltage pulse width based upon feedback information from an encoder.
