Patent EP-0243916-A3 (EP)
Title: Attachment for tubes, bottles or the like
IPC: B65D35/36
Filed: 1987-04-25
Abstract: There is provided an attachment having a pot-shaped bottom element and a sealing cap adapted to be arranged on the neck of tubes, bottles or the like. The top side of the ceiling of the bottom element, which is supported by the side wall of the pot-shaped bottom element, is fitted with brush-like bristles which are covered by the sealing cap. The central region of the bottom element ceiling is provided with an orifice into which projects a tongue extending from the bottom side of the sealing cap, the free end of the tongue entering the orifice in the ceiling of the bottom part and sealing the same in the manner of a plug. The sealing cap has in the bottom edge region a female thread which cooperates with a male thread on the neck of the tube so that the side wall of the bottom element and the female thread of the sealing cap oppose one another in the same cross-sectional plane thus resulting in a space-saving association of the bottom element having the brush-like bristles, such association being close to the neck.

Abstract: Ein Verfahren zum Trennen von Bestandteilen einer hetero­
genen Menge aus festem Material, bei dem das Material 
ggf. zerkleinert, getrocknet und danach in Fraktionen 
getrennt wird, soll vereinfacht werden. Dies wird dadurch 
erreicht, daß das Material auf einem im wesentlichen 
ebenen, geneigt angeordneten Siebboden (3) einer Vibration 
unterworfen wird, die eine der Neigung (8) im wesentlichen 
entgegengesetzte Bewegungskomponente (27) für das Material 
hervorruft, daß das Material von einem den Siebboden (3) 
aufwärts durchquerenden, den Kontakt der Materialteile 
mit dem Siebboden (3) vermindernden Luftstrom (29) 
durchströmt wird und daß die Fraktionen entlang einer 
mit der Förderrichtung (27) einen entgegen letzterer 
offenen, spitzen Winkel (w) einschließenden Linie (5) 
angeordneten Auslaufstellen (ll bis l4) entnommen werden. 
Die Erfindung betrifft auch eine Vorrichtung zur Durch­
führung des Verfahrens.

Title: Control apparatus
IPC: A47L9/28
Filed: 1987-09-16
Abstract: The control apparatus is provided, in particular, for controlling the output of the drive motor of a vacuum cleaner. It contains a circular disc (1) having a control axle (2) which engages in a potentiometer which is adjustable by means of the rotary movement of the control axle (2). Moulded onto the outside circumference of the disc (1) is a flexible, but relatively rigid guide strip (3), the free end of which is provided with a slide element (4). The slide element (4) can be moved along a straight guide portion, the guide strip (3) being arranged between lateral guides. When the slide element (4) is moved in the direction of the disc (1), the guide strip (3) rotates the disc (1) and is thereby wound onto its circumference whereas, with displacement of the slide element (3) in the opposite direction, it is unwound from the circumference of the disc (1) again. The control apparatus requires little space and operates reliably even over a long duration of use (Figure 1). <IMAGE>

IPC: C11D17/08
Filed: 1987-03-23
Abstract: The invention relates to liquid abrasive cleaning 
compositions containing particulate abrasive materials 
stably suspended therein. Increased classification of 
the particulate abrasive materials allows the use of 
particle size distributions with higher mean size,

classification to a particle size distribution such 
that the classification ratio between the upper cut-off 
particle size and the mean particle size is equal to or 
below 2.5:1, products are obtained with very good 
cleaning properties and reduced surface damage.

Abstract: A holographic technique for the detection of position of 
known items so as to be able to reject those samples which do not lie 
within certain defined spatial parameters. A plate (30) which contains 
a single exposure of the three dimensional holographic image of an 
object (10, 12, 14) is illuminated by parallel reference beams from a 
laser (34) to allow the reconstruction of a real focused image of the

Abstract: A method for self-aligning an isolation structure to a 
diffusion region. A first masking layer is formed on a 
semiconductor substrate, the first masking layer 
having at least one aperture sidewall which is sub­
stantially perpendicular to the semiconductor sub­
strate. Dopant ions are implanted into the semiconduc­
tor substrate through the first masking layer to form 
a doped region. Sidewall spacers are then defined on 
the sidewalls of the aperture, and a sidewall image 
reversal process is carried out such that the sidewall 
spacers define trench apertures in a masking struc­
ture. Finally, isolation trenches are etched into the 
semiconductor substrate through the masking structure. 
Alternatively, the implantation step is carried out 
after the sidewall spacers are defined on the first 
masking layer. Alternatively, first sidewall spacers 
are defined, followed by the implantation step and the 
formation of second sidewall spacers.

Title: Method for immunoassay using photoacoustic spectroscopy
IPC: G01N33/543
Filed: 1989-10-17
Abstract: In this invention, antigen-antibody complex is 
labeled with a color material and photoacoustic 
properties of the label are determined by photoacoustic 
spectroscopy. As the color material, a fluorescent 
substance, a dye or colored particles can be used.  
     The immune reaction of the labeled antigen or 
antibody is carried out in liquid under the condition 
that the solid phase is present. As the result of 
immune reaction, the labeled antigen-antibody complex is 
immobilized on the surface of the solid phase. Then, 
the solid phase is separated from the liquid and moved 
to the position for exposure to light and intermittently 
irradiated by the light. An acoustic signal given 
thereby is detected. According to the present inven­
tion, a pressure medium for photoacoustic determination 
is a gas. The method permits to detect antigen or anti­
body with high sensitivity.
