Title: Method of removing inorganic metallic compounds from solutions
Inventor: LEUTWYLER RENE
IPC: C02F1/22
Filed: 1995-02-09
Abstract: Inorganic metallic compounds, particularly salts, ox-ides and hydroxides, are removed from solutions by removing at least a part of the solution liquid and stirring and cool-ing this part while in the metastable state until a crystal-lization of the metallic compounds is rendered possible. Then energy is fed in bursts to the cooled down part in order to initiate the crystallization. The crystallized metallic com-pounds are separated, leaving a residual liquor which then is transferred back to the solution.     Suitable forms of energy are ultrasonic energy, direct current energy, alternating current energy, micro wave en-ergy, magnetic energy, laser radiation energy or ultraviolet radiation energy.     Preferably, the removed part of the solution is stirred and cooled until a first temperature is reached at which an exothermic reaction starts that is caused by the liberation of the heat of crystallization. Then, the liquid is kept at a second temperature which is 0.5 to 1° C below the first tem-perature during 2 to 4 minutes prior to separating the inor-ganic metallic compounds from the liquid.

Patent CA-2156685-A1 (CA)
Inventor: HSIA YU CHUN
IPC: G05D23/24
Filed: 1995-08-22
Abstract: Disclosed is a temperature and pressure  control  means  for water  bed  mainly including a temperature control circuitry and  a  pressure control circuitry.  The temperature control circuitry consists of two temperature detecting elements for detecting  the  atmospheric  temperature  and  the  mattress temperature,  respectivley.   The  detected temperatures are compared  with  each  other  and the resulted value together with a set value from an adjusting circuit are calculated by a  microprocessor to produce a target temperature. When the target  temperature  is  higher  or  lower than the mattress temperature,  a heater is turned on or off, respectively, so that  the  mattress  can be always maintained at a value set according  to the user's preferred temperature even when the heat  dissipation  rate  of  the  quilt  is  affected by the changes  in  the  atmospheric  temperature.   The   pressure control  circuitry  consists of a pressure detecting element for  detecting  the  air pressure inside the air chambers of the mattress.  A signal  representing  the detected pressure is  amplified   and   is   subjected  to  an analog-to-digit conversion  so  as  to  produce  a pressure value.  When the pressure  value  is  higher  or lower than a preset pressure value,  an  air  pump  is actuated to relieve or inflate the mattress,  respectively,  so  as  to  always  maintain   the mattress in a softness most preferred by a user.

Title: Adjunct call handling for accessing adjunct-based capabilities platform
Inventor: BHAGAT PROMOD KUMAR
IPC: H04M3/00
Filed: 1995-10-05
Abstract: A method to allow certain types of adjunct applications for telecommunications networks that require caller interaction during call setup to temporarily access the adjunct and then be released back to the network for routing to the final destination.  Specifically, when the call enters the network, the network originating switch redirects certain calls to the adjunct.  The adjunct may be locally homed directly off the originating switch or may be homed remotely off a centrally located switch. Once the call has been routed to the adjunct and caller interaction has been completed, the adjunct releases the voice connection back to the switch which then routes the call to its final destination.
