Title: Apparatus and process for drying cellulosic and textile substances with superheated steam
Inventor: CURRY DONALD P
IPC: F26B23/00
Filed: 1992-03-10
Abstract: Apparatus and process for the removal of moisture from cellulosic products such as pulp, paper and molded articles, and textile products, wherein gaseous water (steam) in a superheated state is utilized in an energy efficient manner as the drying medium. The apparatus is an enclosed system that operates continuously to dry the products while preventing air contamination from entering the apparatus and thereby reducing its drying efficiency. The apparatus comprises a plurality of drying sections wherein the number of drying sections connected in series is a function of the type and volume of the product or products to be dried. Within each drying section there exists indirect steam heating means, steam-recirculation means, an individual steam-supply chamber, and sections of a steam-return chamber which is open and common to all drying sections in the series. Air/vapor lock chambers at both ends of the apparatus prevent air incursion into the drying sections and at the same time permit a slight amount of excess steam from within the drying sections to vent out of the apparatus. Steam-condensing means located substantially entirely within the drying sections of the apparatus is utilized to recover a large percentage of the energy of the heat of vaporization. The process described herein involves conveying the products into the apparatus and directing the drying steam from the steam-supply chamber onto the products and drawing the spent steam away from the products. The spent steam, which comprises the drying steam in combination with the steam formed by the liberation of moisture from the products, is partially recirculated past the indirect heating means and back into the steam-supply chamber, and partially condensed by the internal steam-condensing means. The velocity at which the drying steam is directed onto the products can be varied in accordance with the type of product to be dried.

Abstract: MATERIAL MONITORING & MACHINE CONTROL SYSTEM                    ABSTRACT OF THE DISCLOSURE:    An automatic monitoring system for monitoring the operation of a punch press, is disclosed.  The flow of material through the punch press and the ejection of punched out parts are typically monitored.  If the material flow is not occurring properly or the punched out parts are not ejected from the area of the punch press, then the operation of the punch press is stopped.  The monitoring of the material flow and part ejection must be done at certain times during the punch press operation.   The timing of the monitoring of the material flow and part ejection is not synchronized to the timing of the actual movement of the punch press operation, however.   The timing of the monitoring is dependent on previous cycles of material flow and part ejection.          There is no direct interconnection with the physical movement of the punch press 6061-1.ABS.Mar.15.91/?

Abstract: TAMPER-EVIDENT TEAR-OFF STRIP FOR CONTAINER CAP  ABSTRACT OF THE DISCLOSURE          A safety  device  for  providing  clues  that a capped container has been opened a first  time. Frictional male female joints releasably  interconnect the  cap to  the container.  This safety device  is of the tear-off  type, wherein  by peeling one peripheral portion  of the  annular wall portion of the container cap, the cap can be released from the  container mouth,  while at least  some  frictional  joints  remain between the cap to enable continuous efficient interconnection capability regardless of the number of  cap opening\closure  cycles.   The peeled cap strip is then disposed off - it is not reusable.  Thus,  its absence about cap signals that someone has already opened the cap to access the content of the container.

Title: Processing method for fabricating electrical contacts to mesa structures in semi-conductor devices
Inventor: HOLMSTROM ROGER P
IPC: H01L33/36
Filed: 1991-09-12
Abstract: A semiconductor mesa structure (20) is covered with a photoresist material (22) in a localized flooding manner such that the photoresist material (22) is thinner on the top of the mesas (21) and also at the uppermost portion of the sidewalls than at the base of the mesa (21) and the intervening channel. The photoresist (22) is then exposed through a mask (23) in a manner so that when developed, the photoresist (22) from the mesa (21) top and uppermost portion of the sidewall can be removed. When the photoresist (22) is exposed to the actinic radiation, the thinner photoresist (22) is adequately exposed more rapidly than the thicker portion nearer the bottom of the mesa (21), if the mask (23) does not adequately shield the actinic radiation from reaching it. Thus the alignment tolerance is greater than if the photoresist (22) were of uniform thickness.
