Patent DE-2712158-A1 (DE)
Title: Determn. of oxygen, carbon mono:oxide and di:oxide - esp. in blood or breath, by photometric measurement of reagent colour changes (SW 14.11.77)
Inventor: ZANDER ROLF PROF DR
IPC: G01N31/22
Filed: 1977-03-19
Abstract: Oxygen, carbon monoxide, and carbon dioxide in gaseous or liquid samples, esp. pulmonary air or blood, are measured quantitatively using a specific reagent for the gas to be analysed which colours when the gas is present, by mixing samples of the gas or liquid with the reagent in known proportions and measuring the change in colour photometrically. The method gives a quick, accurate, and cheap measurement of the gases and the process is simple to carry out. Typically oxygen is determined using a soln. of 5-100 m. moles pyrocatechol/l., 1-20 m. moles ferrous ammonium sulphate/l. and 0.02-5N NaOH. Carbon dioxide is determined using 0.05-0.5 m. moles/l. of fuchsine and 1-10 m. moles/l. of hydrazine. Carbon monoxide is determined in blood by diluting in the ratio 1-200-1-2000 with distilled water.

Title: Chemical dosimeter with constant flow air sampling pump - has integrator and amplifier controlling variable drive pump connected to air filter
Inventor: BAKER WILLIAM BARRY
IPC: G01N1/24
Filed: 1977-10-12
Abstract: The chemical dosimeter is for individual use and collects on a filter particles or vapours present in an air stream which is being pumped through the dosimeter at a constant rate. A variable drive pump is connected to the filter and is driven by an electric motor and controlled by a feed back circuit of an integrator and an amplifier to maintain a constant flow of air through the dosimeter. The integrator receives a signal from a pressure switch that detects changes in the flow of the air stream through the dosimeter by a change in a pressure drop of the air which is being pumped through an orifice. The dosimeter is worn by an individual and at the termination of a period of time, such as a work day, the filter is removed and the collected contents are analysed by conventional techniques such as gas chromatography to determine a level of exposure of the individual using the dosimeter.

Title: Solar heat conversion to power - by water condensed at higher level driving water turbine at lower level
Inventor: SIMONSSON AAKE TEOFIL DIPL ING
IPC: F03G6/00
Filed: 1977-10-22
Abstract: A plant to generate power by the utilisation of solar heat consists of a large solar heat collector above an expanse of surface water. The vapours rise in rectangular or circular solar heat collectors to a condenser at their top end. The water collected in the condenser is allowed to descend into a water turbine at ground level. Before entering the condenser, the kinetic energy of the vapours can be utilised in a wind turbine. This is an ideal way of converting solar radiation to mechanical power.

Title: Horizontal metal band saw - has electronic control to provide automatic advance, overload protection and machine loading
Inventor: SCHMID DIETMAR PROF DR ING
IPC: B23D55/08
Filed: 1977-12-16
Abstract: The effective power of the saw band drive or a related physical characteristic e.g. the tension of the band saw, is measured by a pick-up whose output signal is fed to an electronic controller which is in series with a design value unit.

Patent DE-2803756-A1 (DE)
Inventor: MEIER JOSEF
IPC: B01D29/11
Filed: 1978-01-28
Abstract: In the filtration of high-value liquids, such as beverages, hitherto, the high-value liquid has been displaced from the filter by water, which led to the known blending losses. The present method avoids these blending losses by omitting the displacement by water and forcing out the high-value liquid from the filter after the completion of the filtration process using compressed gas, that is either only into the feedline or partly into the feedline and partly into the discharge line of the filter. Since during this forcing out process, falling off of the filtration residues from the filter surfaces into the unfiltered liquid to be forced out must be avoided, because such filtration residues which have fallen away would have to be filtered out once more in the next filtration process, a special process technique is used in order, during the forcing out process, firstly to constantly maintain a pressure drop from the unfiltered liquid space (1) to the filtrate space (14) of the filter and secondly to ensure that the unfiltered liquid space (1) becomes empty before the filtrate space (14), for which the filtrate space (14) is emptied via a throttled connection line (23) which slows the discharge rate. <IMAGE>

Title: Priming circuit for low pressure fluorescent tube - compensates for mains fluctuations using thyristor control switching as function for electrode potential difference
Inventor: MIONSKOWSKI GERHARD DIPL ING
IPC: H05B41/04
Filed: 1978-11-11
Abstract: A priming circuit for a low pressure gas discharge tube ensures reliable ignition even with fluctuations in the mains supply or tolerance deviation, of the tube.

Title: TDM transmission system with constant synchronisation derivation - compares bit patterns from data with bit pattern from frame
Inventor: TEICH GEORG DIPL ING
IPC: H04J3/06
Filed: 1978-12-21
Abstract: The time multiplex transmission system has a circuit for the continuous derivation and monitoring of the synchronisation criteria. It is obtd. from the bit current. The synchronisation criteria reoccur periodically and synchronisation is est. as quickly as poss. so as to eliminate the recurring interference. The bit patterns formed from the received data are compared with the specific bit pattern of the frame synchronisation symbol. A signal is prod. in the event of concurrence. This signal is used to trigger a flywheel circuit with the periodicity of the time frame when the signal appears within the given time interval. The instant of opening and closing the time window will be determined by considering at least two characteristic results with regard to stability.

Title: Undercut spigot and hexagonal location shoulder - provide installation element for anchor nut, with undercut radial groove
IPC: B21K1/70
Filed: 1979-05-18
Abstract: A cold formed anchor nut, of hexagonal profile (1), is provided with an axial location spigot (2). The cylindrical spigot body is axially compressed so that its free end expands radially. This produces a radially undercut groove (3). An axial shoulder (4) is located between the location spigot (2) and the nut body (1). It has a hexagonal cross section which in installation of the nut is being embedded in the sheet metal panel. Thus the torque applied on the nut is resisted by the hexagonal profile (4).
