Title: Filter for cleaning lubricating oil
Inventor: BAUMANN DIETER
IPC: B01D29/11
Filed: 1988-11-04
Granted: 1993-08-10
Abstract: Abstract of the Disclosure The invention relates to a filter for cleaning lubricating oil, especially for internal combustion engines of motor vehicles, with a filter case which, when installed, is in an at least approximately upright position.  It has a cylinder-shaped oil filter cartridge and an inlet for the dirty oil flowing through the filter cartridge, plus an outlet for clean oil connected to the central interior part of the filter case and situated in a base at the bottom end of the filter case.  A drain passage at the bottom end of the filter case becomes connected to the inlet chamber of the filter case whenever the filter cartridge is removed, plus a closure which cuts the drain passage off from the filter case.  The filter in accordance with the invention is distinguished by the fact that the closure is a valve body which is axially displaceable in the drain passage and which forms a valve together with at least one constriction in the drain passage, that the valve body is pre-biased in the opening direction by a first, weaker spring, and that the valve body can be biased in the closing direction by second, stronger spring which, when the filter cartridge is inserted into the filter case, thrusts against its end facing the valve body.

Title: Speed control system
Inventor: SHIMODAIRA YOSHIKAZU
IPC: H02P25/06
Filed: 1989-02-09
Granted: 1993-05-04
Abstract: SPEED CONTROL SYSTEM          Abstract of the Disclosure In a speed control system for a carriage movable along a predetermined path, light beams originating at the ends of the path are deflected by light conductors aboard the carriage so that they are interrupted, as the carriage moves, by a slotted plate extending along the path.  The light beams are then deflected by light conductors so that they are directed along the carriage path to light receivers situated at the ends of the path.  Electrical pulses from the light receivers are ORed together and converted by a transducer to a signal representative of the actual carriage speed, and by a counter to a signal representative of the carriage position.  The carriage position signal is converted, in accordance with a predetermined functional relationship, to a speed set signal which is compared with the actual carriage speed.  A signal, representative of the difference between the actual speed and the set speed is used to control the driving motor for the carriage.  The speed and position determination achieved by the control system makes it possible to stop the carriage at a predetermined fixed position regardless of the speed of the carriage by initiating braking at different carriage positions, depending on carriage speed.

Abstract: ABSTRACT OF THE DISCLOSURE    An aqueous-alcohol mixture including fructose is crystallized by the inventive process.  The first process step is to feed a hot, fructose, feed stream into an evaporator which immediately cools the feed stream to start a crystallization process.  Then alcohol is mixed into the crystallizing feed stream or magma and the resulting mixture is linearly cooled over an extended period of time.          Thereafter, the crystallized material is collected, filtered, and dried.  The resulting crystals are then sorted by size.          There is no seeding or feeding back of product in order to start the crystallization process.

The used asphalt component is heated separately in a drum mixer operated with parallel flow and the new material component is heated in a drying drum operated with counterflow. After leaving their respective drum devices, the components are conducted into at least one further connected mixer and are further treated there with fresh bitumen and possibly with filler material being added in the mixer. Furthermore, the exhaust gases of the drum mixer are introduced directly into the drying drum and are further heated there, thus combusting the CHx and CO component contained therein. In this process, the exhaust gases of the drum mixer are introduced into the interior of the drying drum in the immediate vicinity of the burner flame through flow channels in the form of nozzles via a feed device formed at the frontal face of the drying drum in which the burner is disposed, with the direction of the nozzles being adjustable as a function of the size of the burner flame.

Abstract: A method and apparatus for adsorption and detection of adsorbents or analytes.  The method and apparatus can be employed in the field for rapid adsorption of analytes and is particularly useful for detection of mycotoxins.  A sample to be analyzed is prepared in solution and placed in a test tube.  A tube-like adsorption column having a seal and a valve member is forcefully fed into the test tube to force solutions through the valve member into the column and through a filter and adsorbent to trap interferences.  The semi-purified solution may then be analyzed for the presence of analytes.  The column with the purified solution may be further employed with a second smaller adsorption column similarly equipped with a seal and valve member fitting within the first column.  In similar fashion the second column may be forced into the first column to expel the solution therein into the second column and through one or more selective adsorbents for different analytes such as one or more mycotoxins.  Detection of the adsorbed analyte may be made by shining a fluorescent or "black" light on the adsorbent which fluoresces to indicate presence of the analyte.
