Title: Heat-developing migration imaging member - enclosed equipment used passes member along on conveyor between two pairs of rollers where it is uniformly exposed to developing heat
Inventor: TAM MAN C
IPC: G03G17/10
Filed: 1991-10-16
Abstract: Equipment for heat-developing a migration imaging member has a migration marking material and a material which softens under heat; it has also a heat source, a conveyor to carry the member past the heat source, and rollers at each end of and touching the conveyor; the member is passed through one pair of rollers on the conveyor and, after passing the heat source, throught the second pair of rollers; the surface temp. of the first rollers is at least 20 deg.C lower than the development temp. of the member whilst they are in contact with the member; the surface temp. of the second pair of rollers is similarly low during their contact with the member; the heat source is held at development temp. of the member during the development concerned. Both pairs of rollers preferably have adhesive coatings of fluorpolymer or silicone, or PTFE, polytrifluormethyl trifluorethylene-co tetrafluorethylene, polyheptafluorpropylethylene, polyheptafluorpropylethylene co-tetrafluorethylene, or polytrifluormethyl trifluorethylene. ADVANTAGE - The equipment does not damage the members and affect the quality of image. It is free from problems of fault colour overlaps when producing xerox printing (colour) masters. The members are fed automatically into the equipment and have only a single pass. Different sizes of member can be treated.
Patent DE-4138369-A1 (DE)
Inventor: HUTH GERHARD
IPC: G01N27/12
Filed: 1991-11-22
Abstract: The invention concerns a method for determining small quantities of carbon monoxide and nitrogen oxides in oxygenated gaseous mixtures, using a sensor whose electrical resistance at high temperature varies with the concentration of carbon monoxide and nitrogen oxides. It is based on the principle that, with the use of suitable sensors, the resistance-temperature curve of one of the gages to be measured differs significantly from that of the reference mixture (one not containing either of the gases to be measured) over a broad temperature range, while the resistance-temperature curves of both the gases to be measure coincide or nearly coincide in one part of that temperature range and diverge significantly in another part of it.

Inventor: CURTIUS FRITZ
IPC: B67D7/04
Filed: 1992-02-02

Title: Pneumatic pressure flushing system for lavatory - uses pneumatic pump to feed used water from shower/bath to lavatory cistern through tube which refills automatically after pump action
Inventor: KRAEMER STEPHAN
IPC: E03D5/00
Filed: 1992-10-16
Abstract: A specific volume of water is taken from a bath or shower tray, or a container connected to it and is fed by a pneumatic pump from a spiral hose or tube, directly into the lavatory cistern. The hose/tube communicates with the water collection container, and refills automatically after use of the pump. Pneumatic pump and hydraulic hose are separated by a flow blockage element, to prevent water entering the pump. The main water flow in direction of the lavatory is controlled by a ball valve, which leaves a small volume of water in the hose, when the pump has been used. The pump volume is slightly higher than the water volume to be conveyed. USE/ADVANTAGE - For domestic use. Reduces amount of fresh drinking water used, resulting in cost savings, and it is environmentally friendly.

Title: Mixing of media of different viscosities e.g. in mfr. of cosmetics - in which low-viscosity medium flows through chamber into which high-viscosity medium is sprayed radially under pressure so that it is atomised and dissolves immediately
Inventor: KULICKE WERNER-MICHAEL PROF DR
IPC: B01F23/47
Filed: 1993-03-15
Abstract: In mixing two media of different viscosity, the medium of lower viscosity flows through a mixing chamber while the medium of higher viscosity is sprayed into it in a radial direction. The novel feature is that the second medium is subjected to a higher pressure and is sprayed into the chamber in such a way that the pressure release causes it to be atomised. The fine particles produced dissolve immediately and without coagulation in the medium of lower viscosity. Also claimed is a device for carrying out the procedure, having a cylindrical housing with inlet and outlet connections on its end surfaces, and a pressure chamber with an inlet for the second medium. Nozzles lead from the pressure chamber through the wall of the mixing chamber. USE/ADVANTAGE - Coagulation of the second medium in the mixing chamber is avoided and a homogeneous mixt. is achieved. The mixing device is also easy to clean and has no rotating parts which might be subject to high wear.
