Abstract: The invention concerns a device (1, 1a) for preparing a stock washing liquor, using powder taken directly from the powder container (7), and storing the liquor for feeding to industrial washing or washing-up machines. The aim of the invention is to enable the stock liquor to be prepared from washing-agent powder (6) taken directly from the powder container (7) containing it, without producing any dust, and to store the liquor thus prepared for supply to industrial washing or washing-up machines. This is achieved using a stock-liquor container (2, 2a), similar in design to an ordinary wet vacuum-cleaner, comprising a tub-shaped bottom section (3, 3a) and a top section (4, 4a) which is hermetically mounted on the bottom section (3, 3a) and is fitted with an integral suction fan designed to generate an underpressure in the bottom section (3, 3a). A suction line (5) leads into the container (2, 2a), the end remote from the container being inserted into the powder (6) in the powder container (7). A fresh-water line (23) also terminates in the container (2, 2a), the water is directed on to the stream of powder passing through the suction line (5). A stock-liquor feed line (25) is operatively linked to a pump to permit liquor to be pumped from an inlet near the floor of the container and out of the container (2).

Title: Detection of end point in etching process for superconducting films - by using film deposited on transparent substrate and measuring light absorbed by film remaining
Inventor: SEEBOECK ROBERT DIPL PHYS DR
IPC: H01L39/24
Filed: 1991-08-21
Abstract: Thin film, especially of a high temp. superconductor, deposited on a substrate with a transmission which is higher than that of the deposited film, is structured by dry etching. During the process the change in film thickness is measured optically. Pref. the transmission, or esp. the first deriv. of the transmission over time, is measured as a function of time during the etching. Etching is carried on as long as the ratio (T(tn)-T(tn-1))/delta(t) in fixed time intervals delta(t) increases. Especially etching is carried out until the condition: T(tn) is not less than (beta)xT(tn-1) in which beta is not greater than exp(alphaf.x.delta(t)) and tn-tn-1+delta(t). Alphaf= deposited film absorption factor and x = the etch-rate. Also claimed are several arrangements of measurement systems. USE/ADVANTAGE - Gives an accurate determn. of film thickness, avoiding problems of detection that other methods have which detect reaction prods. directly or by or fluorescence and allows the etching to be used on small samples. The end point of the etching process is indicated as a sharp change in the property being measured.

Title: Energy generation method from heat in condensates in thermal power station - involves passing condensate through cooler, with turbine condensate acting as cooling medium
Inventor: ECKERT ADOLF
IPC: F01K7/40
Filed: 1991-10-21
Abstract: The heat of the working condensate is transferred with low temp. losses, to the turbine condensate. The condensate passes through a condensate tube (21), a control valve (20), and a cooler (19), before passing into the condenser (5). In the cooler, it transfers heat to a turbine condensate, which is branched off an auxiliary condensate flow from the turbine tube (22) before the low pressure prewarmed (7). The condensate then flows in an auxiliary flow tube (23) with control valve (24), parallel to the main flow, through the cooler. ADVANTAGE - Heat is transferred at low temperature losses.

Filed: 1992-05-15
Abstract: The pipe bending press has the lower piston/cylinder units (8) between the table (12) carrying the lower bending tool (9) and the lower beam (5). The lower piston/cylinder units (8) are controlled separately, with pressure control according to the length of path movement. A non-bending measurement beam (12) extends from one side pedestal to the other (3), parallel to the components which bend under pressure - the table (10) and bending tools (6,9) - acting with a gap monitor (14) to register the movement of the parts (10,6,9) from the rest position when subjected to bending forces. The signals from the monitor (14) set the pressure of the medium fed to the lower piston/cylinder units (8). The lower piston/cylinder units (8) have a common connection for control, leading to a common pressure supply assembly. The lower piston/cylinder units (8) have a common pressure connection to the upper piston/cylinder units. The upper and lower (8) piston/cylinder units are coaxial to each other, and have the same dimensions. USE/ADVANTAGE - The pipe bending press, in a closed frame type, is for bending in large lengths. The structure prevents the bending tool from bending, even when the lower beam can bend under pressure, in a simple construction.
