Title: Oxygen cell with wide temp. range - uses operational amplifier with temp. compensated feedback circuit
Inventor: WALTEMODE GUENTHER
IPC: G01N27/48
Filed: 1977-07-08
Abstract: The oxygen cell features improved accuracy over a wide temp. range unaffected by replacement of the membrane of the cell. The oxygen determining system comprises a measuring cell with electrodes immersed in an electrolyte separated from the fluid being measured by means of a membrane. The cell is connected to the non-inverting input of an operational amplifier (4) whose output is fed back to its inverting input via an indicator (6) and feedback circuit. The feedback circuit comprises a temp. sensitive resistor such as an NTC thermistor (8), in proximity with the cell. A balance potentiometer (9) is associated with the thermistor (9) and connected in parallel with it. A further balance potentiometer (10) and fixed resistors (R2, 3) ensure that adjustments to the slope control (7) and temp. coefficient of the membrane (via balance pot. (9)) are not affected.

Title: Pressure gasification of solid fuels for power generation - with washing of acid gases from the prod. and recycling of carbon di:oxide
Inventor: TOELLE ROLF DR
IPC: C10K1/12
Filed: 1978-10-09
Abstract: In the auto-thermal pressure gasification of solid fuels by mixts. of steam and air, the prod. gas after washing to remove tar and dust is washed with potash soln. to remove acid gases before passing to a combined gas/steam turbine power generation unit in which it is burnt to provide steam and hot gas.

Title: Earth seasonal heating model - has irradiated ball of selected thermal conductivity coated with colour-changing layer, coupled to recorder
Inventor: SZOSTAK ROLAND PROF DR
IPC: G09B25/06
Filed: 1979-03-31
Abstract: Research on relationships between the seasons and temperature as well as climatic changes is carried out with a model simulating the seasonal heating of the Earth. The Earth model (2) is made as a ball of the required thermal conductivity material with its surface coated by a layer changing its colour with temperature. Cooling ensures return to initial colour of the top layer. The rotation axis of the model is set at 23.5 deg. to the earth axis when irradiated from heat source (1). The setting results in beams parallel to the base surface of the assembly, and the ball has markings for the equator, tropics and polar circles. The colour coating ensures a short afterglow effect and the attached resistor of the ball is connected to a recorder. The low-friction bearings of the ball allow either manual or power driving, to take place. An UV radiation source may be used instead of the heat source.

Title: Reversible winch vat for wet-treatment of fabric - having dual compartments with rising and falling false floors
Inventor: JASPER JOSEPH
IPC: D06B17/02
Filed: 1979-12-08
Abstract: Equipment for wet-treatments of fabric in rope or open-width form comprises an enclosed vat divided by an internal partition into two compartments with false floors which are interlinked by a transport mechanism whereby they rise and fall alternately, 180 deg. out of phase. Above the level of the liquor and the partition is a winch roller with an associated cuttling mechanism which can move to-and-fro from one compartment to the other, to pleat the fabric in turn from one to the other. A liquor- circulating system produces a jet of liquor beneath the winch into the compartment into which the fabric is feeding to assist feeding of the fabric. This arrangement gives a uniform, trouble-free pleating of the fabric whereby the distance between the transport mechanism and the top of the pleated fabric remains constant, producing a constant, rather than a varying, mechanical stress in the fabric, and a more uniform treatment.
