Abstract: AHR/KC                 ABSTRACT OF THE DISCLOSURE          The specification describes particle-charging, specie-separating and concentration-enhancing methods and apparatus which operate on a substantially continual basis. The particles of each specie in a mixture are charged by surface contact, separated in an electric field according to  their respective polarites by motion in the direction of the field, and the particles of like net polarities are transported in substantially continuous streams, each of opposite net polarity, running near each other, in a direction or directions transverse to the electric field, the streams being in communication parallel to the electric field, so as to transfer particles of at least one of said species to the other of said respective streams by virtue of continued particle contact and field separation of charged particles as the respective streams progress transversely to the electric field.  The two streams can run in the same direction (co-current) or in respectively opposite directions (counter-current).  The electric field is established between electrodes spaced not more than about 10mm apart.

Title: Latch-up protection circuit fo integrated circuits using complementarymos circuit technology
Inventor: WINNERL JOSEF
IPC: H01L21/8238
Filed: 1987-09-24
Granted: 1990-10-23
Abstract: ABSTRACT OF THE DISCLOSURE        A latch-up protection circuit for an integrated circuit using complementary MOS circuit technology has a substrate bias generator that applies a negative substrate bias to a semiconductor substrate having a p-conductive material into which a well-shaped semiconductor zone of n-conductive material is inserted.  In order to avoid latch-up effects in the integrated circuit, an electronic protection circuit interrupts the capacitive charging currents of a capacitor in the well-shaped zone depending on the potential of the semiconductor substrate which is taken at a doped substrate bias terminal.  The electronic protection circuit disconnects a capacitor bias generator from the capacitor when a voltage on the substrate bias terminal is greater than a difference between a reference potential and a threshold voltage of a first transistor in the electronic protection circuit.  The electronic protection circuit connects the capacitive bias generator to the capacitor when a voltage on the substrate bias terminal is lower than the difference.  A flow forward current flows through the electronic protection circuit during operation of the integrated circuit.

Title: Electronic equipment for control of fluorescent lamps
Inventor: HERBSLEB PEER
IPC: H05B47/11
Filed: 1987-10-21
Granted: 1993-10-26
Abstract: ABSTRACT OF THE DISCLOSURE            A device is disclosed for producing alternating electric current of high frequency for power consumers such as fluorescent tubes.   The device comprises a transformer with a winding connected in series with an output terminal and active electronic components controlling the output current, the active components being controlled by electric voltages  produced  by  inductive  feed  back.    Magnetic saturation is utilized to modify the induction relationship in such way that the active components cyclically change the direction of the output current.   According to the invention the feedback takes place in two magnetic cores, each core being equipped with at least one further electric magnetization winding  designated  a  command winding,  as electric  current  is  fed through the   command windings whereby  magnetic  saturation  of  the  magnetic  cores  is controlled.    In  this  way  a  combined  control  of  the frequency and of the active electric power in a fluorescent tube  is  devised  so  that  the  luminous  power  may  be controlled over a wide range while suitably high voltages are maintained to ignite the tubes properly.

Title: Faying surface structure for guiding and/or positioning of components
Inventor: MILITZER OTTO MICHAEL
IPC: E04B1/38
Filed: 1988-08-04
Granted: 1999-02-16
Abstract: The  invention  discloses  a  faying  surface structure  for guiding and/or positioning of components which  is  introduced  into  the  surface  of  corresponding bodies.    It  is  joined  to  identically  or  differently shaped countersurfaces.   For the locating function,  the countersurface rests on the centrosymmetrical bevels on the  edges  of  abutting  profile  flanks,  thus  providing accurate,  reproducible  and  self-centering  positioning action.   For transition to the guiding function,  there suffices  a  fairly  small  clearance  for  the  relevant structure to leave the locating point and reach another predefined position at a further locating point,  guided between the profile flanks, or to assume an intermediate support position which support being provided sideways from the guidance axis.  The faying surface structure is used   as   three-dimensional   structural   elements,   or integrated into the surface of components for clamping, positioning or coupling applications.

Abstract: ROLLER ASSEMBLY FOR SUPPORTING HOUSEHOLD APPLIANCES     ABSTRACT OF THE DISCLOSURE           A supporting roller assembly for a household appliance includes a fixed rear roller and a height-adjustable front roller.  The front roller has a frame for mounting against a flat surface on the underside of the appliance, together with a vertically extending front wall at the front of the appliance mounting the head of an adjustment screw.  The roller is carried on a roller carrier which is pivotally mounted on the frame member and carries a captive nut engaging the screw so that rotation of the screw causes the roller carrier to rotate about its pivotal engagement to raise and lower the front end of the appliance.  The fixed rear roller assembly has a frame which snaps into an opening in a bottom wall of the appliance. The bottom wall has upwardly projecting flanges which overlay a press-in axle carried by the roller frame and journaling the roller and the flanges prevent any lengthwise movement of the axle which would cause it to disengage from the ears on the frame.
