Title: Dispenser for introducing a treatment preparation into a surrounding liquid
Inventor: BUSCH PETER
IPC: D06F39/02
Filed: 1989-12-28
Abstract: ABSTRACT OF THE INVENTION     A  dispenser  for  introducing  a  treatment  preparation, adapted to be brought into a container through a feed opening, into a liquid surrounding the container through several outlet openings  therein,  in  exact  accordance  with  the  particular application, more particularly over prolonged periods.   The outlet openings are formed by slot-like interstices in parts of an otherwise closed container between a number of thin plates and/or films arranged in the form of layers above one another.       The slot-like interstices between the individual plates and/or films are of such a size that,  depending on the particular plate  and/or  film  materials,  the  surrounding  liquid  is transported by capillary effect into the container to dissolve a  powder-form  treatment  preparation,  and  to  transport  the treatment  preparation  thus  dissolved  or a  liquid  treatment preparation introduced into the container, from the interior of the container to the surrounding liquid.

Abstract: An automated order and payment system for use by consumers to rapidly order products and services from any location at which the consumer is present at the time of ordering.  The system receives information about the products/services to be ordered by means of signals generated by scanning identification codes imprinted in advertising media or displayed to a consumer on a television screen.  A special version of the invention is modified to accept voice command via a voice recognition means for those physically handicapped persons unable to perform manual data entry tasks.  The consumer uses an optical scanning means embodied in a Order Computer Terminal to scan the identification code associated with a company and identification codes associated with the products/services desired.  This product and company information is stored in the Order Computer Terminal along with credit information retrieved from a plurality of storage means used on credit cards and subsequently transmitted when desired by the consumer to a Central Computer System.  The Central Computer System simultaneously receives information from multiple order computer terminals and verifies that the products or services from the desired company are in fact available.  The Central Computer System also verifies the credit worthiness of the consumer by searching for such information from credit data bases.  When the Central Computer System determines that the desired products/services are available and that the consumer is credit worthy, an order verification signal is sent to the individual consumer's order computer terminal whereupon the consumer verifies that he/she wishes to order the products/services communicated to the central computer system.          Once the consumer verifies the order, the automated order and payment system places the order for the products/services desired and provides the appropriate credit reference to the supplier of the product/service.  The automated order and payment system capabilities are more fully set forth herein.

IPC: F26B13/18
Filed: 1990-09-20
Abstract: DRYER SYPHON                      ABSTRACT OF DISCLOSURE   The perimeter and height of an inlet gap to a dryer syphon shoe (for a steam heated dryer drum) are selected to provide an area which at maximum designcondensate flow rate accommodates both condensate and steam flows and in proportions and at speeds that will ensure distributed flow of the steam and condensate while maintaining efficient dryer operation. A plate is positioned inside of the shoe and combines with an inside wall of the shoe to define a transition passage leading from the gap wherein flow is axial of the drum to the condensate return pipe where flow is substantially radial of the drum. The transition passage has a cross sectional area measured substantially perpendicular to the direction of flow that is substantially equal to or less than the area of the inlet gap, provides a smoothtransition for the flow between the gap and the condensate return pipe and insures distributed flow through the syphon.

Abstract: A  distance  sensing  system  includes  an  ultrasonic transducer,  a transceiver and a microcontroller-based signal processing unit.  The  transducer periodically  generates  and directs towards the terrain a dual frequency ultrasonic signal. Echo signals from the ground and/or any intervening crop or trash are reflected back to the transducer and are processed.   The system generates amplified and filtered echo envelope signals. Leading and trailing edge times are determined as the times the echo  signals  cross  a  threshold  value  which  is  a  certain proportion of a maximum echo amplitude value.  A near distance value is derived from the leading edge time of the first echo which exceeds a minimum amplitude.   A far distance value is determined as the trailing edge time of the last echo signal which has an amplitude which exceeds a certain value.  Multiple echo time and amplitude values are derived from the maximum amplitude echo.  These values are used to prevent echoes which occur after the multiple echo time with less than a certain amplitude from being used  in the determination of the far distance value.  This far distance value represents the distance to ground and weaker, earlier echoes from trash or crop and later, multiple echoes may be ignored.
