Abstract: ABSTRACT OF THE DISCLOSURE Quick release means for a pair of footwear.  The quick release means enables one to readily extract one's feet from the footwear without the use of one's hands.  In that regard, each footwear of the pair includes a notch in the toe portion of the outsole and a projection extending generally upwardly from the heel portion.  The removal of the footwear is accomplished when one positions his or her feet so that a portion of the outsole of one of said pair of footwear overlies the projection of the other of said pair, with the notch receiving the projection, therein.          This enables the wearer to readily extract one of his or her feet from one of the footwear.  Obviously, to extract both feet, the first foot is only partially extracted from the footwear initially selected for removal, enabling that same footwear to then be used to extract the other foot from its footwear.

Abstract: ABSTRACT OF THE DISCLOSURE         An electric power generator system includes a switched capacitor controlled induction generator adapted to provide power at a regulated voltage and frequency.  The induction generator system includes an n-phase induction machine having a rotatable input shaft and at least n output lines.  The input shaft is driven at a controlled frequency by a prime mover.  An N-stage, switched capacitor array provides a controlled reactive current to the output lines of the induction machine.  Each stage of the array includes a capacitor network associated with each of the permutations of pairs of the n output lines.  The capacitor networks for each stage are characterized by substantially the same capacitance. Each stage further includes an associated switch network associated with each capacitor network for selectively coupling the capacitor network across its associated pair of output lines. A feedback network is coupled between the output lines and the capacitor array to adaptively control the switching of the various N-stages in and out of operation.  In grid-connected operation, the feedback network includes a power factor detector for producing  a signal representative of the power factor at the output lines of the induction machine.  The feedback network uses this power factor signal to control the switched capacitor array to adaptively vary that net capacitance across the output lines of the induction generator so that the generator presents a unity power factor to the grid.

Abstract: COMMUNICATIONS SYSTEM EMPLOYING   CONTROL LINE MINIMIZATION            ABSTRACT      A communications system (100)  employs a multiline bus (101) including control lines (103 and 104)  for multiple functions in order to minimize the required number of bus lines.  This technique is most applicable to small computer systems which are hand portable or briefcase portable and which operate with small peripherals. The transmitting device (106) places an active signal on a handshake line (103) for a predetermined period of time.  The receiving device (107, 108 and 109)  detects this active signal and also places an active signal on the handshake line. The transmitting device applies valid data to the data lines (102)  throughout the period that a active signal is on the handshake line (103). Upon detection of the data the receiver releases the handshake line.  Using this technique a single line (103) is used to indicate valid data transmission and proper reception.  An additional bus available line (104), used by a master device (106)  to alert slave devices (107, 108 and 109)  that communications is in process, can be employed by at least some of the slave devices (107, 108 and 109) to request service from the master device (106).

Abstract: Abstract:   A hanger for a necktie or similar elongated article of clothing.  The hanger has two parts, namely attachment portion and a holder for the tie or other article.  Prefer-ably the attachment portion is a hook, but anyway should be such that the hanger can be suspended from a rack or similar support.  The holder has several straight, gen-erally horizontal bars for holding and gripping the tie or other article.  The attachment portion is connected to the holder, but is readily detachable therefrom.  The bars of the holder are interconnected in such a manner that the holder can be used as a paper clip when the attachment portion is detached therefrom.  In this way, the hanger has a secondary use, i.e., as a paper clip, once its primary use as a garment hanger has been fulfilled.

Abstract: ABSTRACT         Optical wave-guiding components and a process for fabricating such components in a substrate using conventional integrated circuit fabrication techniques.  Ions of a suitable dopant are selectively implanted in a silicon substrate to create an interior region defining a wave-guiding region of a first index of refraction.  A wave confining region surrounding the wave-guiding region is created by oxidizing the silicon sub-strate.  The wave confining region has an index of refraction lower than that of the interior wave-guiding region defined by the implanted dopant.  Various configurations of components, from which various optical component characteristics can be obtained, are disclosed.  The optical components also may be combined with electronic circuit components formed on the same silicon sub-strate.

Abstract: ABSORPTION TYPE HEAT TRANSFER SYSTEM     FUNCTIONING AS A TEMPERATURE PRESSURE POTENTIAL AMPLIFIER                       ABSTRACT     An absorption type heat transfer and thermally powered temperature pressure potential amplifier system for storing energy by distilling and separating solute from a solution of the solute and a solvent at a low temperature, then amplifying and recovering the temperature and/or vapor pressure potential difference between the solute and the solution at a higher temperature in the form of heat transfer or its mechanical power equivalent.  One working fluid is a solute having a low boiling point, the other a solution of the solute in a solvent having a high boiling point such that mutual solubility is poor at low tempera-tures as indicated by a small vapor pressure difference between solute and solution, and in which the vapor pressure difference between solute and solution greatly increases at higher temperatures.  This permits the vapor pressure potential difference to be released in the form of mechanical work when vapor from separated solute is reabsorbed into solution in an absorber at the higher temperature.  Similarly, an amplified temperature differ-ence exists between liquid solute and absorbent solution in a high temperature absorber when solute vapor passes freely into solution within the absorber.  The working fluids are circulated in a closed cycle with an inter-mediate counter-flow heat exchange means for exchanging heat between separated solute and solution moving from the colder distilling means, and recombined warm solution returning to the colder distilling and separating means from the higher temperature absorber.  This system utilizes low grade heat from natural sources.

Abstract: Abstract It is a known phenomenon that the web during the drying moment in a paper machine shrinks. The shrinkage in the machine direction can be controlled by arranging the different driving groups in the drying section to oper-ate at different speeds. The shrinkage in cross direct-ion, however, heretofore was not brought under control.          The present invention has the object to solve thos problem.            According to the invention, the problem of shrinkage is solved in that the web during a certain drying inter-val is subjected to outward directed forces, which are applied during a suitable drying interval and preferably at a low dry content, for example directly after the press section.
