Title: Combination plate for ceramic firing kiln - incorporates wave-form or smooth fibre parts connected 0.5-3 mm thick ceramic cover plate
Inventor: GOLLER RALF
IPC: F27D1/06
Filed: 1991-06-18
Abstract: A ceramic cover plate (1) of corundum with a thickness e.g. of 2 mm is connected via a fireproof adhesive to a layer of wave-form or smooth insulating fibre parts (3). An essentially thicker base plate (4) of e.g. 15 mm thickness can comprise schamotte with a clay content, i.e. less resistant material, since it is not exposed to the aggressive kiln atmosphere. As an alternative, fixture can be by means of pins which project into the wave valleys of the wave-form insulating fibre parts. This version has the advantage that adhesive is not used at the points which face the interior of the kiln, with only ceramic material facing the heat. USE/ADVANTAGE - A combination plate for ceramic firing kilns which has favourable heat insulating properties and a corrosion-resistant upper surface.

Title: Method to convert heat into work, using Stirling engine - uses temp. differential to generate gas volume differential, and produce work output
Inventor: PAPADOPOULOS MOISSIS
IPC: F02G1/044
Filed: 1991-07-17
Abstract: Gas is isothermically expanded from the heat source and is returned to original condition by isochoric cooling, isothermic compression, and isochoric reheating. After isothermic expansion of the complete gas volume, a first part volume is isochorically cooled. A second part volume is maintained at max. temp. but is in pressure-compensating connection with the first volume, and transverse gas to it due to pressure reduction. The connection is then blocked, the first volume is isochorically reheated, the second volume is compressed at the max. temp., and transfers the generated heat to the heat source. Reestablishing of the connection unites the two part volumes, and these are recompressed to max. pressure. USE/ADVANTAGE - Environmentally friendly conversion of heat into work using Stirling engine.

Title: Ultrasonic flowmeter receiving reflected ultrasonic signals by array of transfer elements - executes Fourier transformation w.r.t. orientation of received signals and processes result as sequence of two=dimensional signals
Inventor: KATAKURA KAGEYOSHI
IPC: A61B8/06
Filed: 1992-03-02
Abstract: The speed of phase rotation of the received ultrasonic signals is calculated. The angular speed dependent on the direction is detected on the basis of the relationship between the phase rotation speed and a speed componenet of a reflective subject at right angles to the dirction of the beam. A drive source repeatedly controls a part of the transfer elements (Q) at a predetermined timing for transmitting an ultrasonic wave at regular intervals to a target. A parallel receiving beam shaper (B) aligns the phases of the signals from the transfer elements and produces parallel reception signals from the received beams with different directional dependence. A scanner covers all the parallel received signals and stores the resultant signals. A display filter shows a moved object by using a difference imaging process. USE/ADVANTAGE - Pulsed ultrasonic Doppler effect flowmeter for clinical medical use, underwater measurements and similar. Highly effective for measuring blood flow through heart. Simple construction able to measure distribution of flow speeds.

Inventor: FUKUHARA KAZUO
IPC: D04B15/96
Filed: 1992-03-09
Abstract: On a flat knitting machine having two beds of needles in an inverted V formation, there is a cam carriage on each side. These have a traversing drive for each, and the carriages are not coupled at the bow. Additionally, a position regulator is fitted to one of the carriages. The knitting machine (1) has two beds (2, 3) and cam carriages (6, 9) traversing the needles, on the rails (4, 7). Driving the carriages are endless belts on wheels at the front and back of the machine. The drive is coupled back and front to a cross shaft (30) which has a coupling (50, 51) to engage or disengage, and brakes (52, 53). The transmission is then driven by an electric motor (36). By means of another smaller motor which is superimposed on the rear carriage (9), electronic controls are arranged to ensure that the cam is positioned with accuracy. This facilitates the transfer of stitches, as required.
Patent DE-4211092-A1 (DE)
Inventor: RIES-MUELLER KLAUS DIPL ING
IPC: F01N7/00
Filed: 1992-04-03
Abstract: The methods described for assessing the operatability of a catalytic converter fitted in the exhaust of an internal-combustion engine make use of the fact that the conversion-onset temperature for a catalytic converter is higher the older the catalytic converter is. Improved variants of the invention also make use of the fact that, after conversion has started, a catalytic converter produces less heat per unit time from the combustion of oxidizable exhaust components the older it is. A first method is designed to investigate when a catalytic converter starts converting and to designate the converter as operable when the measured temperature lies below a given comparison temperature. A second method is designed to operate the catalytic converter in accordance with precisely defined conditions and to investigate how long it takes for conversion to begin. If the measured length of time is less than a comparison time, the catalytic converter is operable. A third method is designed to estimate the temperature of the catalytic converter by means of a model. As soon as the estimated temperature reaches a comparison temperature, the temperature of the catalytic converter is  measured to determine whether it has exceeded the estimated temperature. If this is the case, the catalytic converter is considered to be operable. Devices as proposed by the invention include equipment for carrying out the operations necessary for the methods described.

Abstract: The cleaning turbine maintains the clarity of the quartz sheath tube by a mechanical brushing action along the outside of the tube (1). The turbine (10) surrounds the tube and is propelled by a traversing arm (20) which supplies water under pressure to nozzles (16) with jets impinging on the vanes (11) of the rotor. Typically, three brushes (14) bear on the surfaces of the tube with a light pressure and rapidly rotate with the turbine rotor to remove the layer deposited by the flow of sewage. After a cleansing traverse of the turbine the complete equipment can be withdrawn to a parking position outside of the UV radiation area. USE/ADVANTAGE - Simple, compact cleaning equipment which can readily be applied to whole series of tubes in UV radiation channel.

Abstract: In a measuring device for detecting the travel position of a first body with respect to a second body of a device, for example a shock absorber, having two bodies (piston 10 and cylinder 4) movable relative to each other along a travel path, a continuously variable position signal, corresponding to the travel position of the piston (10) is produced along the travel path, and a marking signal is produced by additional means (82) for at least one defined travel position thereof. The fine, continuous position signal is thus corrected at precise position(s) and measuring errors are minimised. The device described uses coil(s) on the piston (10) and a conductive tube (60) around the cylinder and provided with a V-slot (68). The marking signals at precise positions are produced by slots (82) in a further tube (80). Coil (40) is supplied with a.c. at two frequencies. <IMAGE>
