Title: Dialysis membrane comprising hollow cellulose fibres - connected in parallel to fibre axis, extruded from cuprammonium soln. of cellulose
Inventor: DUENWEG GUSTAV
IPC: D01D5/20
Filed: 1979-02-21
Abstract: A dialysis membrane of cellulose regenerated from cuprammonium solns. is in the form of hollow fibres with a continuous empty space. The membrane consists of >=2 hollow fibres spun together, and joined in a parallel direction to the axes of the fibres. The membrane is mfd. by extrusion of a cuprammonium soln. of cellulose into an aq. caustic soda soln. through the annular slit of hollow fibre die immersed in the aq. caustic soda soln. A liq. which will shape the empty space is extruded through the inner passage of the die. The ratio of the speed of drawing of the hollow fibre over the first drawing roller to the speed of extrusion of the cumprammonium soln. of cellulose from the annular slit is 1-1.05. The direction of the fibre follows from the die to the first drawing roller forms an acute angle, pref. 15-70 degrees with the axis of the die apertures. Subsequent treatment of the fibres is conventional. The membrane is used partic. in haemodialysis; it can also be used for reverse osmosis. It shows improved activity w.r.t. known hollow fibre membranes.

Title: Low-noise TV tuner - has separating stage transistor amplifier between input circuit and tunable band filter
Inventor: HEINDORF WILLI
IPC: H03F3/193
Filed: 1979-02-26
Abstract: The low and constant signal-to-noise ratio of the t.v. tuner ensures operation in all conditions of reception including localities with a weak signal. The unit does not produce interferences for other equipment and it includes a tunable input followed by a first stage connected to a mixer. The latter is preceded by an adjustable band filter with a transistor amplifier acting as a separation stage. The transistor operates with a common base allowing a high current while the first stage includes a dual gate MOSFET.

Title: Bearing reverse rotation lock - has ball rolling under gravity down ramp face in one component
Inventor: STUMPF WALTER
IPC: A63C17/14
Filed: 1979-03-08
Abstract: The reverse-rotation lock is for a plain, ball- or roller-bearing, having an inner body with circular peripheral face enclosed by a concentric outer ring, a wedge-shaped chamber being formed between the two and accommodating a clamping body. The wedge-shaped recess (1) in the one component contains a ball (2), whose diameter is smaller than the maximum distance between the surfaces forming the chamber. On reverse rotation of one of the components, the ball rolls over the downwards-sloping ramp face (9) solely under its own weight.

Title: Rolled steel prods. with multilayer microstructure - where prod. leaving hot rolling mill is quenched intermittently to obtain several layers of tempered martensite
Inventor: SCHMITT WOLFGANG DIPL ING
IPC: C21D1/19
Filed: 1979-04-21
Abstract: Steel leaving a hot rolling mill at above the A3 point is subjected to multistage intermittent quenching so transformation to martensite occurs in layers; and a specific temp. equalisation time is used after each quenching period so the core of the steel and the martensite layer reach the same temp. Equalisation temp. for the outermost layer of martensite is pref. below A3; and quenching is pref. discontinued at equalisation temps. above Ms, esp. at 450-650 degrees C. Esp. used in treatment of hot rolled steel rod intended for reinforcing concrete, so the dynamic load carrying capacity of the rod is increased.

Patent DE-2932563-A1 (DE)
Inventor: LEWIS DAVID MALCOLM
IPC: D06M13/278
Filed: 1979-08-10
Abstract: Reactive dyes are allowed to strike polyamide textile fibres at room temperature and a pH of about 2; the dyeing liquor has been adjusted to this pH with trichloroacetic acid. The temperature of the dye bath is then slowly raised to the boil and kept thereat until the dye has been fixed. Upon boiling, the trichloroacetic acid decomposes into chloroform and CO2, whereby the pH of the bath rises to about 7.5, i.e. to a value at which fixing next occurs and free dye is inactivated. The dyeings obtained are very level. Exhaustion and fixing requires less time, and there is a saving of chemicals.
Patent DE-2937660-A1 (DE)
Title: Rise and fall curtain track with cable and pulley - has movable part which adjoins and locks with fixed part to prevent runners from falling (AT 15.5.80)
Inventor: MISNER KURT ING
IPC: A47H7/02

Title: Coffin inside cooling plant - with twin hose to refrigerator compressor for air recirculation
Inventor: GROENEWEGEN ARIE PAUL
IPC: A01N1/00
Filed: 1979-10-26
Abstract: Cooling system for the inside of coffins, esp. for use in hot countries in summer and when a burial is delayed for any reason, consists of a trestle for the coffin and a motor driven compressor unit with condenser, expansion valve and evaporator below the trestle. A twin hose blows cool air through a perforated distributor tube in the coffin and the second hose which is also led inside through the partly lifted coffin lid recirculates the air.
