Patent DE-2654864-A1 (DE)
Title: Independent gas turbine and heat exchanger entry temp. limiting - uses greatest deviation from set limits as fuel control signal
Inventor: HAGEN HERMANN DR
IPC: F02C9/54
Filed: 1976-12-03
Abstract: The unit limits the entry temperatures (T3, T5, T6) of the compressor-driving turbine (12) and a heat exchanger (16) and a possible additional power turbine (14) of a gas turbine unit. The temperature limits are independently adjustable to required levels. The temperatures are compared with the desired limits (T3 max, T5 max, T6 max), and the differences so found are then themselves compared in a logic selector circuit (18), the greatest difference DELTA beta then being used to actuate a temp. regulating device (17). The entry temp. (T3) of the turbine (12) may be limited indirectly by limiting its exit temp. (T5) to a value depending on its speed(N1) or on this speed (N1) and the compressor entry temp. (T1) which takes account of the temp. drop in the turbine.

Title: Cervical passage expanding instrument - comprises tapered bar screwing into spring steel tube with tapering tongues
Inventor: KYNAST JUERGEN DR MED
IPC: A61M29/00
Filed: 1976-12-15
Abstract: The instrument rapidly and simply expands the cervical passage, having at the lower end a tube with an internal screw thread, pref. of spring steel. This joins onto pref. four tapering tongues of the same length and dia. as the passage, and has a rounded bead to avoid perforation, being coupled to a wingnut-shaped handle. A bar with a tapering end screws into the tube and also has a wingnut handle, causing the tongues to expand slowly. Compared with the existing method using glass or metal bars of different dias. the instrument is more rapid in operation and gentler to the patient.

IPC: C07D211/70
Filed: 1977-03-14
Abstract: 11-Deoxyprostaglandins of formula (I) and the salts with pharmaceutically acceptable bases when R1 is H are new: (R1 is H or alkyl, R2 and R3 are together oxo or SCH2CH2S; or one is H and the other OH. R4 is H or alkyl; R5 and R6 are H or alkyl. R7 is H or alkyl. n is 3-6, m is 2-8. A is CN, COOH, alkoxycarbonyl, N-disubstd. carbamoyl, OH or acyloxy).

Title: Liq. phase prodn. of aliphatic alcohol(s) - from carbon mon:oxide, hydrogen and acetylene over iron catalyst
Inventor: KAGAN JULIJ BORISOVITSCH
IPC: C07C29/36
Filed: 1977-05-24
Abstract: Prepn. of 3-20C aliphatic alcohols (I) consists of the treatment of CO, H2 and C2H2 in a liq. solvent with a catalyst at 170-220 degrees/20-200 atmos. Solvent is a fraction of satd. 10-18C aliphatic alcohols and/or 12-20C paraffin hydrocarbons. Catalyst contains 92-95% Wt. Fe3O4, 0.5-2 wt.% K2O or Na2O (alkaline promoter); and 3-7.5 wt.% V2O5, Al2O3, and SiO2 (as structural promoter). Process allows increased C2H2 concns. to be used, thus increasing the reaction rate and process space-time yield. A constant temp. may be maintained over the catalyst bed, and the accumulation of high m.pt. prods. on the catalyst is avoided. The thermal stability of the process is greater, and the catalyst has a longer life.

Title: Heat exchange system - with two coolant circuits and monitors admitting water from mains supply in case of circuit failure
Inventor: DREWS KLAUS
IPC: F25D29/00
Filed: 1977-06-04
Abstract: Heat exchange system utilises two coolant circuits, one of which transfers heat energy to the other in a heat exchanger. In case the heat energy receiving circuit should fail, the heat emitting circuit is automatically connected to the public water mains. This prevents excessive heating of plant which must be cooled, even when the heat energy receiving circuit or the heat exchanger itself should become defective.

The support plate can be square, with posts at the corners forming the support and also the distance pieces, so that a round cheese placed between the posts is accommodated entirely inside them and the support plate.
Patent DE-2733930-A1 (DE)
Title: Low pass filter for DC or mains frequency AC - with resonant frequency damping provided by inherent resistance variation
Inventor: MOURICK PAUL DIPL ING
IPC: H02M1/12
Filed: 1977-07-27
Abstract: The filter is intended for use on power frequency or dc circuits, for example on the input and output of an inverter. The system frequency is thus between 0 and 50 or 60 Hz, and the filter resonant frequency around 300-360 Hz. The filter comprises a series inductor and a parallel capacitor. The damping of resonant and higher frequencies is improved by constructing the inductor (12) such that, at these higher frequencies, the current concentration in the conductors increase rapidly and thus raises the effective ohmic resistance of the coil. The change in resistance is determined by the dimensions, in partic. the radial dimension, of the conductor used in the winding, and the shape of the magnetic field of the inductor.

Title: Continuous washing process including cold soak treatment - used for printed fabric lengths
IPC: D06B3/16
Filed: 1978-03-04
Abstract: In a continuous washing process using very wide washing machines, a printed textile sheet, with its colours already fixed, is first wetted, then soaked in a folded state, then relieved of its water. Immediately after this, the textile is submitted to wash currents passing from the outside inwards on revolving perforated drums, pref. in several washing phases.
