Patent DE-3725504-A1 (DE)
Inventor: THRAENHART OLAF
IPC: G01N33/543
Filed: 1987-07-31
Abstract: In a process for detecting proteins with antibody-specific or antigen-specific properties in body fluids or other organic substances, a protein attached to a support takes part in a specific reaction with the protein to be detected in the solution, which renders the latter protein insoluble. A second protein in the solution, provided with a marker, reacts with the insoluble component and thereby becomes insoluble. This makes it possible to examine blood directly, without centrifuging, in order to detect one or more proteins simultaneously.

Title: Control arrangement for a flat display device
Inventor: NEUSCH MICHAEL
IPC: H01J9/14
Filed: 1989-04-07
Abstract: In a control arrangement (16) a line-selection electrode layer (12) serves to define lines, that is to say to select in the column direction. A line is therefore selected; the selecting direction is the column direction. A column-selection electrode layer (13) serves to select column. The selection direction is the line direction. Each line-selection electrode layer is produced from metal sheets (11.s) in which the rolling direction runs in the line direction. In contrast, the column-selection electrode layers are formed from individual metal sheets (11.b) in which the rolling direction runs in the column direction, that is to say at right angles to the line direction. The different rolling directions mentioned ensure that in each electrode layer the rolling direction is at right angles to the selection direction. This results in the fact that geometric displacements, such as can occur during temperature processes and which are particularly strong in the rolling direction, have only little effect on the positioning accuracy of the electrode layers. <IMAGE>

Title: Method for synchronously driving pulse-controlled invertors
Inventor: HOFMANN WILFRIED DR ING
IPC: H02M7/5395
Filed: 1989-05-06
Abstract: The invention describes a method for obtaining synchronous pulse patterns for driving pulse-controlled invertors, especially for supplying three-phase machines which are operated at a low pulse frequency. The principle is a method in which, starting from a discrete control voltage vector, decomposition into edge vectors and zero vectors is carried out (triple method) by projection with respect to the two adjacent edge vectors which are offset by 60@ respectively. It is proposed to detect the control voltage vector which leads by half the triple range at specific detection times and to convert it into corresponding invertor switching states, via the triple range, in accordance with the pattern according to the invention.

Title: Lock e.g. for switch cabinet door - allowing blind fitting, with reliable earthing between key and door
Inventor: RAMSAUER DIETER
IPC: E05B9/08
Filed: 1989-10-03
Abstract: (A) A lock (e.g. latch lock), for fixing in a hole in a sheet panel (e.g. switch cabinet door) by means of an earthing and/or fastening spring, has a housing, which merges into a flange seated on one panel side and which has opposed axially-aligned peripheral flats or recesses. A spring is fitted on the housing portion extending through the hole to seat on the other panel side and fix the lock in the hole, thus providing electrical connection between the panel and the spring and between the spring and the housing or a lock shaft mounted in the housing. The novelty is that the spring (534) has one or more rough or sharp edges (67) which, on insertion of the spring-bearing housing (511) through the hole, scrape along the hole sidewall (69) and/or the edge between the hole sidewall and the panel (26) back face. In the housing end position, in which the flange (30) seats on the panel front face, the scraped-base hole sidewall regions contact the bare metallic part of the spring, the spring being connected with the housing (if electrically conductive) and/or with an electrically conductive part (e.g. lock shaft or cylinder) which receives or holds the key and which is mounted in the housing. (B) Prodn. of a spring for the lock (A) comprises (a) stamping a spring blank from steel sheet while simultaneously forming openings, eyes, edges and/or chamfers; (b) hardening the spring blank; and (c) opt. fitting the spring onto the lock housing. The housing may consists of plastics such as polyamide. ADVANTAGE - The design allows blind fitting of the lock when access is allowed only to the front face of the panel, while ensuring satisfactory earthing contact between the key and the panel esp. when the lock housing consists of non-conductive plastics.
