Title: Measuring light intensity variations
Inventor: UDDEN PER
IPC: A61B3/113
Filed: 1988-09-20
Granted: 1993-03-30
Abstract: Abstract The invention relates to measurements of light, where light variations superimposed on a background amount of light, which is changing relatively slowly, are measured. To give the light sensitive element (3,3') used a stable operational point a light emitting element (5,5') is used for injecting extra light into the light sensitive element (3,3'). Thus, the amount of light injected by this light emitting element (5,5') is chosen in such a way that the sum of the ambient light and the injected light is substantially constant. To this amount of light are added the light variations, e.g. caused by a second light emitting element (9,9'). This process and device can be used in a device for measuring the eye movements of a person.

Abstract: A dishwashing machine having a box-like closed main frame with a front vertical opening and a door for closing the front opening.  A hinge pivotally interconnects the bottom edge section of the door to the bottom front edge section of the main frame.  A latch releasably lockingly anchors the top edge section of the door to the top front edge section of the main frame.  The machine is characterized by the way the door joins with the main frame of the dishwasher when the door is closed: the side and top edge sections of the door inner face have two spaced outturned projections forming a continuous U-shape cavity, and the front and side edge sections of the top and side walls of the dishwasher main frame define an inturned U-shape cavity.   The U-shape cavities engage each other when the door is closed, to prevent water escape but to allow air circulation through the joint.

Abstract: IMPROVEMENTS IN THE PREPARATION OF COPPER ARSENATE       ABSTRACT     Copper  arsenate,  substantially free from impurities that will  form a sludge  in the process  for producing wood preservatives such as chromated   copper   arsenate and having  a  water content of less than 15%,  is  prepared by mixing a solution of soluble arsenate and a copper sulfate  solution,  either  or  both  solutions  containing sludge-forming impurities,   to form   a   copper   and arsenic-containing     solution     without precipitating copper   arsenate.     The pH during   the   adding   is controlled   at a value in the range of 1.7 to 2.2 to precipitate  impurities.    Precipitated  impurities  are removed, and the  copper and  arsenic-containing solution is  neutralized with   a   suitable alkaline  substance, preferably dilute sodium hydroxide  solution, to  pH  3.2 to 4.2 to precipitate copper   arsenate.     The   water content of the copper arsenate is reduced by adding to the copper and  arsenic-containing  solution,  either  in  the mixing of arsenate solution with copper sulfate solution or in the precipitation of copper arsenate, an amount of soluble chromium in the range of about 0.005 to 0.250 gram chromium per litre of solution.
