Abstract: ABSTRACT OF THE DISCLOSURE      A utility knife comprises a lower elongate part shell and an upper such part shell forwardly fitted with interengaging wedging surfaces whereby they clamp together on relative longitudinal movement.  This movement is achieved by turning a nut on a shank which extends rearwardly from one part shell through the rear wall of the other part shell, so that the nut bears upon this rear wall.  Loosening of the nut unclamps the part shells and thus permits a blade carried on a slider within the part shells to be pushed forward by a protruding pushbutton.  Such loosening does not separate the part shells since an end spur of the shank still rides on a transverse arresting web of the upper part shell.  Maximum unscrewing of the nut, however, permits separation e.g. for access to stack of spare blades resiliently held in the rearward part of the lower part shell 1 (now unencumbered by the conventional screw-shank), but does not lead to loss of the nut because a complementary detent configuration at the end of the shank and in the end wall of the nut prevents complete nut/shank separation.  The end spur can be upwardly sloping at its underside and thus constitute an auxiliary clamping means for the lower part shell against the upper part shell.

Abstract: A process for the decaffeination of raw coffee.  The process involves increasing the moisture content of the raw coffee and selectively extracting caffeine from the raw coffee by using hydrous liquefied carbon dioxide as an extractant at a pressure below the critical pressure of carbon dioxide.  The process differs from conventional processes which use liquefied carbon dioxide at pressures above the critical pressure but it is surprisingly found that the process of the invention does not result in the co-extraction of aroma components of the coffee.  The use of lower pressures means that the process of the invention is more economical than conventional processes.

Title: Container for storing contact lenses and conditioning them with a liquid that releases gas
Inventor: HAYNES THOMAS P
IPC: A45C11/00
Filed: 1988-12-02
Granted: 1993-02-23
Abstract: ASTRACT OF THE DISCLOSURE A storage container or carrying case for contact lenses has a screw-on cap on which baskets for hanging the lenses vertically inside the canister are swingably suspended on a hinge plate which also holds the annular gasket for the cap closure when it is screwed down on the canister.  A single helix thread on the outside of a tubular extension of the canister, for meshing with a similar internal thread on the rim of the cap, has a vertically running gap of a few degrees in width and a shallow channel is recessed in the flat flange surface just below the threading at the same orientation as the gap in the thread.  The tightness of the closure is thereby readily adjustable to prevent leakage of a treating solution for the lenses from the closed canister in the event that it is knocked over while at the same time permitting escape of gas when the treating liquid includes hydrogen peroxide and a wafer is provided near the flat bottom of the canister to activate or modify the peroxide action.

Abstract: ALTERNATING SEQUENTIAL HALF DUPLEX COMMUNICATION SYSTEM          ABSTRACT OF THE DISCLOSURE     A  message communication system employing  one or  more centralized  communication  stations  transferring  messages through  Earth orbit repeater satellites to or  from  mobile terminals  with at least one central  communication  station having   a  first  transceiver  for  transmitting  a   first communication signal to one or more mobile terminals and  at least  one mobile terminal having a second  transceiver  for receiving  the first communication signal  and  demodulating it,  and for transmitting at a predetermined duty  cycle  of the second transceiver, a second communication signal to  at least  one  of  the  central  communication  stations.   The preferred  duty  cycle over which the  second  communication signal  is transmitted is about fifty percent of the  second transceiver duty cycle.  The communication system uses  Time Division  Multiplexed  (TDM) communication signals  using number  of channels as designated address channels with  the remainder   being  used  for  data  transfer.   Information transmitted on the address channels is used by terminals  to determine   both   the  presence  of  a  message   and   its corresponding  data transmission or reception  channel.   In addition  the  terminals  use the  reception  of  the  first communication  signal  to adjust  return  link  transmission frequency  to compensate for transmission path errors.   The alternating  duty  cycle allows mobile terminals  to  use  a single  set of local oscillators for both  transmission  and reception modes of operation.  To decrease interference with other  systems the present system employs a power  dispersal [2536MPA7.A18]            - 1 -modulation  function  to achieve the footprint  of  a  video signal for high transfer rate digital communication signals.

Granted: 1991-11-26
Abstract: AUTOMATIC HAND DRYER               Abstract of the Disclosure An automatic hand dryer contains a heating element and a motor which drives a squirrel cage fan.  The fan exhausts air past the heating element to a downwardly-directed outlet.  A base or mounting plate is adapted for flush mounting to a wall.  The axis of the fan is perpendicular to the base plate and wall to which the dryer is attached.  A control or sensing circuit emits signals to a detection zone beneath the outlet and monitors the zone for reflected signals indicative of a user's presence.  The circuit operates to energize and deenergize the power circuit to the fan motor and heating element.  Upon detection for a predetermined period, the circuit energizes the power circuit. The control circuit deenergizes the power circuit upon interruption of the reflected signals for a predetermined period, or after a predetermined maximum time period of continuous detection.  Under the latter condition, the stimulus reflecting the emitted signals must be removed from the detection zone to reactivate the control circuitry.  Any incremental  interruption in the reflected signal which does not exceed the period of permitted interruption, restarts the commencement of the timing of the maximum period of continuous detection.
