Abstract: A method of separating metal particles where particles of the one metal exhibit a higher degree of friction against a surface than particles of the other metal, particularly for separating lead particles and copper particles one from the other. In accordance with the invention a layer of a mixture of the metal particles is deposited, by means of a feed conveyor (4) or the like, onto the peripheral surface (8) of a drum (3) which rotates about a horizontal axis (7). The material is deposited at a location on the drum (3) spaced at a distance (a) from a vertical plane (10) through the drum axis (7), in a direction opposite to the rotational direction of the drum, this distance (a) being adapted so that those particles which exhibit greater friction against the peripheral surface (8) of the drum (3) than the other particles are carried by the drum in its direction of rotation, while the other particles are moved in an opposite direction gravitationally.

Title: Method and sensor electrode system for the electrochemical determination of an analyte or an oxidoreductase
Inventor: HOENES JOACHIM
IPC: C07D295/073
Filed: 1991-02-01
Abstract: (A) The determn. of an analyte (I) comprises electrochemical reaction in the presence of an oxido-reductase (II) and a reducible substance (III) which, in the course of the reaction, transfers electrons from (II) to an electrode, thus giving rise to a signal which is a measure of (I). (III) is enzymatically reduced. Oxidn. occurs on the electrode, with the substance produced by this oxidn. being different from the original (III). (B) A substance which is capable of taking up electrons from a (II) to form an electron-rich aromatic amine can be used as an electron carrier between a (II) and an electrode in an electrochemical system. (C) A sensor electrode system for the electrochemical determn. of (I) in which a sample contains at least 2 electrically conducting agents which are isolated from each other and which are each brought into electrical contact with the sample (I) via an electrically conducting surface, so that at least one of these surfaces is in contact with a (II) and a (III) which is capable of transferring electrons between the (II) and the surface. The (III) used is a cpd. which, after redn. by (II) can be oxidised on the surface to give a substance different to the original (III).

Abstract: A safety closure, particularly safe in the hands of children, to safety close containers composed of an assembly of an inner cap (3) and an outer cap (2), the inner cap (3) provided with threading (9) for screwing onto the mouth of a container. The outer cap (2) can be depressed over the inner cap (3) against a resilient force provided by lips (12) coating with a conical surface. When depressed, teeth (16) on the outer cap (2) mesh with teeth (14) on the inner cap (3) to effect unscrewing of the closure. A ratchet provided by teeth (18) on the inner cap (3) cooperating with tangential protrusions (19) on the outer cap (2) enable onscrewing of the closure but prevent offscrewing. A guarantee seal (22, 23) may be provided, ruptured automatically on depressing the outer cap (2), and also, if desired, on rotation of the outer cap (2) in the offscrewing direction.
