Title: Variable clamped memory cell
Inventor: LAYMOUN SAMIR M
IPC: G11C11/415
Filed: 1987-06-08
Granted: 1991-04-02
Abstract: ABSTRACT OF THE DISCLOSURE           An improved memory cell circuit in which the collector of the "ON" transistor is clamped to a variable voltage level to prevent saturation. Saturation is prevented by providing a mechanism for limiting the voltage between a first node in the word line circuit and the collector of the conducting transistor to a first level, while limiting the voltage between the first node and the collector of the nonconducting transistor to a second, lower level.          In one embodiment, clamping transistors have their emitters coupled to the collectors of the memory cell transistors and their bases coupled to the word line.  A common resistor couples the load resistors of a plurality of memory cells to the word line.           In a second embodiment, the common resistor couples the bases of the clamping transistors to an intermediate node in a Darlington driver for the word line.

Granted: 1991-07-23
Abstract: ABSTRACT     A cooling tower assembly comprising at least first and second layers of fill within the tower chamber, each of the first and second layers of fill having a source of water introduced  above  the  fill  for moving  through  gravity downthrough the fill during the cooling process.  There is further included an upper fan member circulating at the top portion of the tower for drawing air through inlet panels along the walls of the tower through the first and second layers  of  fill  to cool  the  water  as  it  is percolating through the fill contents.  The first and second layers of fill would be separated by a horizontal baffle member so that air pulled through the lower layer of fill would be prevented from the first layer, but would flow through a centrally located air flow chamber within the upper layer of fill  to  be  drawn  out  of  the  chamber  by  the  fan.   In addition, water percolating down through the upper layer of fill would not contact the second layer of fill, but would be distributed into a water holding chamber in the lower portion of the  tower via  a plurality of drain pipes  to prevent the overloading of water into the lower portion of fill during the water cooling process.

Title: Apparatus for crimping pipe
Inventor: CASTRICUM WILHELMUS P H
IPC: B21D41/04
Filed: 1987-10-22
Granted: 1991-04-09
Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus for crimping the leading edge of continuously produced spiral pipes is disclosed.  The apparatus includes upper and lower passive crimping rollers, which are rotatably mounted adjacent each other in a holder.  The holder is carried by a guide rail system which slides in the axial direction of the spirally moving pipe.  The holder and rollers are rotated between a down position, where the continuously produced pipe will move freely over the crimping apparatus, and an up position where the leading edge of the pipe will pass between the upper and lower crimping rollers.  When the crimping apparatus is in the up position and the leading edge of the pipe is between the crimping rollers, the lower roller is raised until the rollers cooperate to crimp the leading edge of the pipe.  The spirally moving pipe will exert a force on these rollers, which causes the guide means, which car-ries the rollers, to move axially with the pipe.  The crimping rollers will crimp the entire circumference of the pipe's leading edge as the crimping rollers move axially with the pipe and the leading edge of the pipe rotates between the rollers.  When the entire leading edge of the pipe has been crimped, the holder and rollers are rotated to their down position, so that the pipe pro-duction can resume without obstruction by the crimping apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE      A bib of a type for covering a major portion of the upper front torso of the wearer, such as an adult hospital patient, and formed in an economical manner so that it can be used as a disposable garment. The bib is formed of a single sheet of thin flexible material having an outline defined by a bottom edge, a pair of side edges, and a top edge having a scooped central portion to be received around the front of the neck of the wearer and a raised portion on either side of the central portion, between the central portion and the respective side edge. A pair of ties are formed in-tegrally with a main central body portion, each tie being formed inwardly of its respective side edge and raised portion by a separation line which begins at a bottom end of the tie, extends upwardly and then inwardly and then downwardly to a termination point spaced laterally outward from the central portion so that the tie remains integrally attached to the main body portion.  The separation line is spaced along its length inwardly from the side edge, and raised and central portion of the top edge a distance defining the width of the tie. The main body portion is made a width to extend well across the chest of the wearer and when it is put on the wearer, the ties separate from the main body portion and can be tied around the wearer's neck. The raised portions of the main body portion which are on either side of the neck receiving scooped portion project well up towards the shoulders of the wearer, thus providing good protection to the wearer.  The sheet of material from which the bib may be formed a rein-forced tissue coated on one side with a liquid imper-vious plastic, or it can formed from other treated paper products or non-woven material which is pleasing to the touch.  Because the shape of the bib, including the formation of the separation lines can be formed by a simple cutting or stamping process, the cost of manufac-ture can be sufficiently low that it is feasible to dispose of the garment after a single use.

Abstract: LINE GENERATION IN A DISPLAY SYSTEM ABSTRACT    The present invention concerns a line generator and a method for determining the individual pixels to be plotted for a line to be drawn in a display system.  Coded representations of a plurality of lines are stored in a line definition table, the coded representation of each individual line comprising a string of data items representing the transitions between adjacent pixels to be plotted for drawing said individual line.  Preferably, only coded representations of lines up to a predetermined size (ie. the length of the line in the case of a straight line) are stored in the line definition table and strings of data items for representing the pixels to be plotted for longer lines to be drawn are still calculated as in the prior art.  In this case, means are provided for determining whether there are coded representations of a line to be drawn in the line definition table, or not, and for passing control to the  appropriate logic for determining the pixels to be plotted.  In a preferred embodiment, the string of data items forming the coded representation of a line to be drawn is a string of binary digits and the value of each bit in the string represents a transition in one of two directions.  This provides a very compact representation of the line.
