Abstract: Computer Human Interface ABSTRACT      In  a computer human interface an adjustable "window" enables  the user to view a portion of an abstract,  device-independent  "picture" description  of information.  More than one window can be opened  at  a time.  Each window can be sized independently of another, regardless of the  applications  running  on them.  The  human  interface  creates  a separate  "object" (represented by a process) for each  active  picture and for each active window.  m e pictures are completely independent of each  other.  Multiple  pictures can  be  updated  simultaneously  and windows  can be moved around on the screen and  their  sizes  changed without  the  involvement of other windows and/or pictures.   Images, including windows,  representing  portions  of  any  or  all  of   the applications  can  be  displayed  And updated  on  the  output  device simultaneously  and independently of one another.  All human  interface with  the  operating system is performed through virtual  input/output devices,  and  the system can accept any form of real input  or  output devices.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed herein is a chart and a preferred method of using it.     The chart consists of predetermined measurements printed, preferrably on a durable paper.     The chart is designed to give double fullness to drapes. This is accomplished by the pleated and the unpleated areas being the same width.     Vertical numbers 1-27 get progressively larger.  They determine, by moving horizontally down the chart, the location of each pleated and unpleated area.     Horizontal lines start out progressively larger and they then continue to be drawn the same width down the remainder of the chart, approximately 13 feet 6 inches.     These lines determine how wide the pleated and unpleated areas are to be.

Abstract: ABSTRACT         In file cabinets and drawer storage assemblies, where drawer slides are employed, a unique anti-rebound device not only cushions and resists rapid closure of a drawer but also resists reopening of the drawer by rebound.  The slippage outward of the drawers when the cabinet is moved out of a vertical position is also eliminated, except when an external force is applied to pull open the drawer.  The unique elongate anti-rebound member has resilient sides which deflect when engaged by two protruding lugs on the inner channel of the drawer slide.  The device fits onto an end flange of the outer channel and is positioned between the intermediate and inner channels so that no loss of space or strength occurs.

Title: Protection of thyristors during turn-on
Inventor: CREES DAVID E
IPC: H01L29/74
Filed: 1988-07-25
Granted: 1992-04-14
Abstract: Abstract:      A thyristor having a main cathode 1 and an anode electrode 2 between which conduction occurs, also includes a region of long charge carrier lifetime 12.  During forward conduction between the cathode 1 and anode 2, carriers diffuse into the region of long lifetime region 12.  If, during reverse recovery, but prior to the thyristor recovery time, a positive going voltage ramp is applied across the device, turn-on is initiated in the long lifetime region 12 due to the presence of unrecombined charge and displacement currents generated The current produced is limited by resistors 9 and 17 to prevent damaging high levels and is used to switch on the remainder of the thyristor (via an amplifying gate) without any damage to the device occurring.  In previous thyristors not including a region of long carrier lifetime, such a voltage might result in turn-on occurring over only a very small volume and the heat dissipated could destroy the thyristor.

Title: Polycarbonate shutter in horizontal sections
Inventor: ESNAULT PAUL
IPC: E05D15/12
Filed: 1988-07-26
Granted: 1992-09-29
Abstract: ABSTRACT OF THE DISCLOSURE           A movable shutter to be placed over an opening is made up essentially of horizontal sections,  each of which sections comprise an intermediate section or filler of polycarbonate.  A male extrusion is fixed to the filler at the top and a female extrusion at the bottom.  This makes it possible to assemble the sections together.  The shutter is guided by rollers carried by the sections.   These rollers move in vertical guiding tracks fixed on the opening and continue on horizontal tracks mounted from the ceiling.  The operation of the shutter is made easier by means of a compensation spring fixed above the opening.   An anti-dislocation lock is mounted forcibly inside or attached onto two partitions of the female extrusion.  When the ball and socket of a hinge are interlocked,  the guide and the shoulder of the anti-dislocation lock are superimposed and their respective holes are aligned.  Thus, after the roller axle is inserted in the aligned holes, the extrusions can no longer become dislocated whatever the angle of rotation of the hinge.
