Abstract: ABSTRACT            SET OF HARDWARE FOR MOUNTING A HINGED AND SLIDABLE DOOR ON A BOX UNIT OF FURNITURE              A set of hardware for mounting a hinged and slidable door (5) on a box unit of furniture (1 to 4) comprises hardware elements (8, 9, 18, 19, 20, 23, 25), which define a pivotal axis for mounting said door (5) and comprise slide track means which are adapted to be mounted to extend parallel to said pivotal axis and to a wall (1) of the box and to guide said door (5) into the box when the door has been swung open. To permit a substantial use of commercially available, simple com-ponents and a simple adaptation of the hardware elements to doors differing in size, the slide track means com-prise two track rails (8, 9), which are adapted to be mounted so as to be spaced apart and to extend horizon-tally. A trolley (19, 20) is associated with each of said track rails and comprises rollers guided on bearing sur-faces of the guide rails. The trolleys (19, 20) are adapted to be interconnected by a mounting plate (23) on that side of the rails which faces away from the wall (1) of the box. The door (5) is hinged to said mounting plate (23) by means of furniture hinges (25). Carriage stop means (11, 15 ) are provided for limiting the move-ment of the carriages (19, 20) along the rails (8, 9). Adjustable door stop means (26, 27) are provided for co-operating with the door (5) in its closed position at those edges of the door which extend from the edge at which the furniture hinges (25) are provided.

Title: Self-orienting device
Inventor: GREEN RICHARD F
IPC: G10K11/00
Filed: 1987-11-12
Granted: 1991-05-07
Abstract: SELF-ORIENTING DEVICE       ABSTRACT       A  self-orienting  device  is  disclosed  for  a transducer adapted to be dropped from an aircraft or other vehicle.   An elongated body is provided with first,  second  and  third  arms  each  of  which  is pivotally connected with the body for pivotal motion between a stowed position parallel to the body and an erect position perpendicular to the body.   The first and second arms are disposed on opposite sides of  the  body  and  the  third  arm  is  disposed therebetween.   An  actuator spring  is  provided on each arm urging it from the stowed position to the erect position and a tubular housing over the arms and body retains the arms in the stowed position. The  third  arm  is  also  retained  in  the  stowed position by a separate releasable retainer.   After the  transducer  comes  to  rest  on  the  ground,  an ejector spring is released to separate the housing from the arms and  the body whereby the  first and second arms move to the erect position.   After a predetermined time delay, the retainer on the third arm is released; if the body is lying right-side-up, i.e.  with the third arm on the upper side of the body, the third arm will move to its erect position so that it is oriented perpendicular to the ground. If the body is in the wrong-side-up position before release of the third arm, the pivotal motion of the third arm will  flip  the body  over  to  the  right-side-up  position  and  the  third  arm  will  be perpendicular to the ground.

Title: Ionic dressing of topical administration of drugs to wounds and burns
Inventor: YAMAZAKI HIROSHI
IPC: A61L15/16
Filed: 1988-04-22
Granted: 1993-09-14
Abstract: ABSTRACT OF THE DISCLOSURE    Novel wound or burn dressings are provided herein.   Such dressings  provide  for  the  systemic  administration  of  a physiologically- or biologically-active agent by controlled release of the agent into such wound.  Such dressing includes a substrate, e.g. in the form of a fabric or cloth at least a portion of which is cellulosic, which has ionic exchange sites thereon, e.g. by being  chemically-modified  to  convert  hydroxyl  groups  in  such cellulosic portions to ionic-adsorbing sites.  An ionic form of such  physiologically- or biologically-active agent is absorbed therein,  e.g.  by ionic bonding.   Ionic bonds hold that agent temporarily to the substrate for controlled release therefrom in proportion to the amount of exudate in contact with the substrate.          The  ionic  bonds  are  formed  by  adsorbing  that  agent  on  that substrate at room temperature.  The ionic bonds disassociate upon contact with body exudate from wounds to which the wound dressing is applied by ion exchange with ions in the body exudate, thereby to release that agent in an amount proportion to the amount of the exudate in contact with the substrate.  This controlled release thus reduces unnecessary exposure of unwounded skin surface to the physiologically-or biologically-active agent.

Title: Method for producing circuit board with deposited metal patterns and circuit boards produced thereby
Inventor: CHANT PETER R
IPC: H05K3/00
Filed: 1988-12-12
Granted: 1991-03-05
Abstract: ABSTRACT    A process for producing circuit boards involves the coating of a temporary subsrate with a fluid mixture of an epoxy polymer component and a rubber polymer which is interactive therewith at temperatures of at least 180°F.          Preferably the rubber is a low molecular weight polyfunctional reactive  butadiene/acrylonitrile  interpolymer  which  is terminated by vinyl or carboxyl functional groups.  The rubber component comprises at least 70 percent by weight of the epoxy polymer component,  and the coating has a thickness of 0.001-0.015 inch.  The coating is air dried upon the temporary substrate, and then the coating is transferred to the resinous substrate of the circuit board by heat and pressure.  The coating is partially cured to effect partial polymerization of the epoxy prepolymer, further polymerization of the rubber, if it is of low molecular weight, and interaction of the rubber and epoxy polymer to form a matrix of the interacted rubber/epoxy.  The exposed surface of this coating is then etched,  and metal is deposited on the surface to form a conductive layer.  A conductive pattern is formed therein, and heat and pressure is applied to at least the conductive layer and coating to fully cure the coating and bond the coating to the conductive layer, and thus the conductive pattern to the resinous  substrate.   The metal  layer may be deposited chemically or by vacuum metallizing and like techniques.    The present invention relates to circuit boards, and more particularly to a novel process for producing circuit boards in which a conductive layer of metal forms a circuit pattern upon, and is firmly bonded to, a resinous substrate providing the support therefor, and to the well defined and bonded circuit boards which are produced thereby.

Filed: 1989-02-06
Granted: 1994-04-05
Abstract: WRITE HEAD CONTROLLER             ABSTRACT OF THE DISCLOSURE A system for precisely positioning a printing element relative to n rotating drum, as in a drum printer, employs two position signals for alignment purposes.  A pair of linear grids is disposed along a path of travel of the printing element for generating, with the aid of optical beam and sensor devices, a periodic electric signal which varies in accordance with printing element position.  One of the grids is stationary and the second of the grids moves with a carriage supporting the printing element.  An encoder positioned alongside the drum is operative with a set of markings having a variation in spatial frequency, or a grid overlay, to produce an alternating electric signal which varies in accordance with rotational position of the drum.  Motors which rotate the drum as well as a lead screw which translates the printing element may be constructed as synchronous motors to permit phase locking to each other.  Circuitry responsive to periodic signals outputted by the linear grids and the encoder introduce phase shift between  motor drive signals to align position of the printing element with position of the drum independently of any backlash which may be present between the lead screw and the carriage driven by the lend screw.

Abstract: ABSTRACT OF THE DISCLOSURE          A method and arrangement for preventing the locking out of devices which are coupled to a bus by either of two of the devices which have become initiator and target devices respectively. The devices arbitrate for control of the bus after the bus enters a bus free phase. The device which wins the arbitration becomes an initiator. A timer in each device on the bus is started upon the initiation of the arbitration. The initiator device is removed from the bus when an elapsed time after the timers have been started reaches a pre-determined value. The distributed clock of the invention ensures that the devices coupled to the bus will clear the bus after the initiator has been on the bus for a pre-determined time, thereby obviating skew problems associated with single clocked systems.
