Title: Improvements in the formation of melt-spun acrylic fibers
IPC: D01F6/18
Filed: 1989-08-21
Abstract: An acrylic multifilamentary material possessing 
an internal structure which is particularly suited for 
thermal conversion to high strength carbon fibers is 
formed via a specifically defined combination of 
processing conditions. The acrylic polymer while in 
substantially of acetonitrile and water 
concentrations (as defined) of acetonitrile and water 
is melt extruded and is drawn at a relatively low draw 
ratio which is substantially less than the maximum draw 
ratio achievable. This fibrous material which is 
capable of readily undergoing drawing is passed through 
a heat treatment zone wherein the evolution of 
residual acetonitrile and water takes place. The 
resulting fibrous material following such heat 
treatment is subjected to additional drawing to 
accomplish further orientation and internal structure 
modification and to produce a fibrous material of the 
appropriate decitex for carbon fiber production. One 
accordingly is provided a reliable route to form a 
fibrous acrylic precursor for carbon fiber production 
without the necessity to employ the solution-spinning 
routes commonly utilized in the prior art for 
precursor formation. One can now eliminate the 
utilization and handling of large amounts of solvent as 
has heretofore been necessary when forming an acrylic 
carbon fiber precursor. Also, acrylic fiber precursors 
possessing a wide variety of cross-sectional 
configurations and a highly uniform internal structure 
 
 
now are made possible which can be thermally converted 
into carbon fibers of a similar cross-sectional 
configuration which are substantially void free when 
examined in cross section at a magnification of 2,000X.

Title: Spring coil and spring assembly
IPC: A47C23/043
Filed: 1987-05-15
Abstract: A spring coil (11) has an open-ended terminal convolution (11b, 11c) which is connected to the body (11a) of the coil through a gradient arm (20) which can be varied in length in manufacture to alter the spring compression and firmness. Offset portions (12, 13, 14) are formed on each terminal convolution with a major straight part (13a) which is outwardly spaced from minor straight parts (13c) for a three point engagement for the offset portion to a border wire (18). The offset portions (12, 14) have inside (25a) and outside (25b) shoulders adjacent their ends, with the pitch of joing cross-helicals (17) chosen so that a cross-helical simultaneously engages the outside shoulders of a pair of overlapped offset portions (12, 14). The spring rows are further arranged across the width of the mattress, with the columns extending along the length. Cross-helicals (28) can then be used across portions of the width for extra firmness for the entire mattress, or for selected areas, such as the middle third.

Title: Electronic watt-hour meter with combined multiplier/integrator circuit
IPC: G01R22/00
Filed: 1989-11-25
Abstract: An electronic watt-hour meter includes a multiplier/integrator 
circuit which performs "pulse height-pulse width" multiplication of 
current and voltage and simultaneously integrates the product of this 
multiplication to generate packets of electrical charge representative of 
the electrical energy consumed. A first set of switches alternately, at 
one-half the frequency of a pulse width modulated (PWM) signal having a 
duty cycle proportional to the current, connects one of a pair of 
capacitors to be charged by the voltage signal, and the other capacitor 
to dump charge into an accumulator. When charge in the accumulator 
reaches a preset value, a  pulse is generated representing a 
predetermined unit of energy.  
     When the first capacitor is connected to the voltage signal by 
the first set of switches, a second set of switches applies the 
voltage to the first capacitor in one sense when the PWM signal has one 
value and in the opposite sense when the PWM signal has a second value. 
Similarly, a third set of switches alternates the polarity in which the 
voltage signal is applied to the second capacitor as a function of the 
value of the PWM signal.  
     The second and third sets of switches also determine the polarity 
of charge transferred to the accumulating means from the first and 
second capacitors respectively in response to a polarity signal which 
indicates the direction of integration of charge by the accumulating 
means.

Title: Fault tolerant computer memory system with disablement feature
IPC: G06F12/16
Filed: 1990-02-02
Abstract: In a memory system comprising a plurality of memory 
units (10) each of which possesses unit-level error 
correction capabilities (20) and each of which are 
tied to a system level error correction function (30), 
memory reliability is enhanced by providing means 
(Fig. 2) for disabling the unit-level error correction 
capability, for example, in response to the occurrence 
of an uncorrectable error in one of the memory units. 
This counter-intuitive approach which disables an 
error correction function nonetheless enhances overall 
memory system reliability since it enables the 
employment of the complement/recomplement algorithm 
which depends upon the presence of reproducible errors 
for proper operation. Thus, chip level error 
correction systems, which are increasingly desirable 
at high packaging densities, are employed in a way 
which does not interfere with system level error 
correction methods.
