Title: Immunological diagnostic method for detecting and determining antibodies
Inventor: NICULESCU VLADIMIR FLORIN
IPC: G01N33/543
Filed: 1981-06-05
Abstract: The invention relates to an immunological diagnostic method for detecting and determining antibodies with the aid of antigens which are located on supports and bind the antibodies. A second, labelled, antibody which is directed against the first antibody is added and reacts with the first antibody. The antibody bound to the antigen is detected via a particular activity of the label. The antibodies are added in the form of serial dilutions to the antigens, and the specific activity of the label on the final product of the reaction is determined in the form of a measured value (y). To determine the specific value (y') of this measured variable, a specificity control or measurement is carried out only with the labelled second antibody. The resulting measured value (reaction background) (y'r) is subtracted from the measured value (y), and an end point titre (dN0) for y = 0 is determined from the resulting specific measured value (y'). To do this, the measured values (y') are plotted as a function of the concentration (x) of the antibodies. The end point titre (dN0) is then determined by calculation of the regression (a, b), where dN0 = x = 10-(b/a).

Title: Sanitary single-lever mixer tap
Inventor: ZWINK HELMUT
IPC: F16K11/078
Filed: 1981-06-20
Abstract: In a sanitary single-lever mixer tap, the cap which closes off the top of the housing of the fitting cannot be tilted but can be rotated together with the handle. The handle reaches around or over the cap; a strut which passes through the cap on the side facing away from the user establishes the connection between the handle and the pivoted lever arranged under the cap. The pivoted lever, for its part, is in operative connection with the regulating elements of the mixer tap, for example with known ceramic discs. By means of the arrangement described, the gap between the cap and the remainder of the housing of the fitting is kept extremely small in all the operating states. The opening in the cap required to establish a connection between the handle and the pivoted lever is situated on the side facing away from the user where there is little risk of splashing or soiling and where it is furthermore largely concealed from the view of the user. A description is given of special adapters by means of which it is possible to use conventional control cartridges with the handle and cap according to the invention. <IMAGE>

Title: Tape-cassette recording apparatus
Inventor: OISHI KENGO
IPC: G11B15/087
Filed: 1982-06-28
Abstract: A tape-cassette recording apparatus is provided with a device for recording variously encoded address signals on a magnetic tape and with a device for searching the tape for a specified address during playback. Before an item of information is recorded, an address signal selected according to the type of information to be recorded is first of all recorded on the tape, whereupon the information is recorded after this address. When the code of an address signal is specified upon playback, the recording tape is moved at relatively high search speed, and when one of the address signals which has the specified code is detected, the tape-running speed is reduced to the playback speed in order to play back the information following the address signal. When, after completion of the information playback, the next address signal is detected, the forward tape-running speed is again increased to the search speed, in order to determine the next address signal bearing the specified code. Consequently, all items of information of the desired type, according to choice, are played back. In the case of such a cassette recorder, a device for displaying the code of the specified address signal before its actual recording on the tape is provided. The specified address signal is not actually recorded until an enter button is operated.

Title: Process and plant for prepasteurising liquids, in particular sewage sludge
Inventor: MENGES MARTIN DIPL ING
IPC: C02F1/02
Filed: 1982-08-23
Abstract: The process for prepasteurising infected liquids, in particular sewage sludge, is characterised in that one or more delay vessels are divided by a membrane into two separate chambers. The total vessel volume can as a result be used twice at the same time. The process is distinguished in particular in that if two vessels are used, a continuous passage process is achieved. The process is of great use to the economy, because it reduces the investment costs of a pasteurisation plant to a level which enables it to be used even in relatively small waste water treatment plants. By this means, a sanitary improvement of the overall sewage sludge situation can be improved with low financial expenditure. A further benefit lies in the fact that with the exact separation of treated and untreated media the process offers the best guarantee of success.
