Patent DE-2629402-A1 (DE)
Title: Arterio-venous blood oxygen concn. gradient - calculated from three points on respiration gas curve for oxygen and carbon dioxide concentrations
Inventor: REIS AUGUST PROF DR MED
IPC: A61B5/083
Filed: 1976-06-30
Abstract: New non-bloody method is for measuring the gas concn. in venous mixed blood, partic. the difference in the oxygen content of arterial and venous blood. The respiration gas curve is taken by measuring three fixed points on it or the areas between them. The measurement of the CO2 concn. by an analyser is triggered by an O2 analyser reaching three predetermined equally spaced thresholds. The formulae stated in the Patent can then be evaluated by a computer of the analogue type. This provides simple and reliable evaluations of the desired parameters. It does not require the availability of a data processing plant with a large computer.

Title: Horizontal transfer track with drag hooks on endless chain - has deflector cam for disengaging hinged hook arm which pivots about horizontal axis
Inventor: GREGG HAANS
IPC: B65G19/02
Filed: 1976-09-03

Title: Turbine cleaning machine with liq. dispensing nozzles - has spring biased protective cover over nozzle orifices movable only by pressure of cleaning liq.
Inventor: CARSTENSEN JES
IPC: F02B77/04
Filed: 1976-09-15
Abstract: The cleaning machine for turbines is provided with a wash nozzle (1) which is mounted in the waste gas pipe wall (2) of the turbine and is provided with a nozzle head (3) having nozzle orifices (4) which can be covered by a protective member (5). This protective member (5) which can be cylinder, cap or plate shaped to displaceable in the longitudinal direction of the nozzle so as to open the nozzle orifices during cleaning and close them after the cleaning time. Since these orifices are normally kept closed by the protective member no combustion particles can block them up to hinder the spray of cleaning fluid during the next cleaning process. The shape of the protective member can be matched to the shape of the orifices in the nozzle head and the nozzle head itself. The protective member can be spring-biased in the closing direction and thus only displaced in the opening direction through the pressure of the cleaning fluid.

Title: Toaster browning control - consists of two sensors measuring conductivity of toast surface, with amplifier and potentiometer
Inventor: WILHELM DIETER
IPC: A47J37/08
Filed: 1976-10-28
Abstract: The control for the degree of brownness of toast toasted in an electric toaster consists of inducing the electrical conductivity on the surface of the toast by means of contact measurement. When a set figure is reached, the electrical conductivity is incorporated in switching off the heating. The conductivity is measured between two sensors inserted in the surface of the toast at a pre-defined distance. The sensors are loaded with a measurement voltage, and the current flowing between them is converted electronically in an nversely proportional voltage signal. An amplifier is used to conver the measurement current into the voltage signal. The amplification factor of the amplifier is set by a pre-set potentiometer with a scale of browning degrees. The voltage is conducted via a threshhold value diode to the cut-off device.

Title: Titanium tri:chloride component prodn. for Ziegler-Natta catalyst - by treatment with carbon mon:oxide, giving satisfactory induction period
Inventor: BRONSTERT KLAUS DIPL CHEM DR
IPC: C08F10/00
Filed: 1977-03-28
Abstract: In the prodn. of a TiCl3 catalyst component for Ziegler-Natta-type polymerisation catalysts, an appropriate catalyst component consisting (mainly) of TiCl3 is exposed to a CO atmos. at 0.1-10 (esp. 0.5-1 bar) for 0.5-60 (esp. 5-15) min. at -20 to 100 (esp. 10 to 30) degrees C.

Title: Non-slip underlay for foam backed carpets - comprises evenly spaced foam strips connected by woven threads
Inventor: SCHULZ WILFRIED
IPC: A47G27/04
Filed: 1977-07-08
Abstract: The underlay is formed by rectangular section foam strips (11 of equal width connected together and held spaced from each other by woven-in textile threads (12, 13, 14). The wide sides of the strips lie parallel to the main surface of the underlay (10) and run parallel to each other in warp manner forming with the threads a woven structure. The foam strips are held loosely in the textile fabric (12, 13, 14) so that a transverse expansion of the strips is possible when the latter are compressed during wear. The spacing x between the strips which is produced by the woven-in threads ensures there is sufficient freedom of movement so that no bulges occur in the carpet. Furthermore even on a smooth floor the carpet has a non-slip effect due to the gaps between the individual strips.

Title: Phosphonic and phosphinic acid prepn. from their ester(s) - by acid-catalysed hydrolysis under autogenous pressure using excess water
Inventor: BLOCK HANS-DIETER DIPL CHEM DR
IPC: C08G79/04
Filed: 1977-10-13
Abstract: In phosphonic- and phosphinic acid prepn. by hydrolysis of the esters, catalysted by the acids formed, hydrolysis is effected under a higher pressure, pref. under autogenous pressure at 105-235 degrees C. The reaction mixt. contains at least double molar water quantity w.r.t. molar quantity of acidic OH gps. forming and/or present. The acids are used as corrosion-inhibitors and sequestering agents or as intermediates for the prodn. of corrosion-inhibitors, sequestering agents, flame-retardants textile auxiliaries and anti-statics. High saponifification rates are achieved. Discolouration and decompsn. of the acids at high reaction temps. e.g. above 150 degrees C is prevented. The dissociated alcohols may be recovered without conversion to dialkyl ethers. Water excess maintains dilution of reaction mixt. and reduces relative volatility of light esters, so that separation from alcohol-water mixts. distilling off is obviated. Pure acids and alcohols are recovered in quantitative yields.
