Title: Xenon lamp with constant light output - has ring shaped magnets behind electrode adsorbing metallic vapour and volatile matter
Inventor: SUGA SHIGERU
IPC: H01J1/50
Filed: 1977-02-02
Abstract: The xenon lamp has a light output which remains constant for a long operating period. The wall of the bulb is not blackened as the metallic vapour or volatile substances will be adsorbed. The adsorber consists of magnetic pieces, so that only the magnet will become blackened. The magnets (8, 8') are fitted inside the bulb on the same fitting as the electrodes (9, 9'). The magnets are in the form of partially slit rings. They are located between the discharge section of an electrode inside the bulb and the end of the tube along the same axis. The volatile substances or metallic vapour are produced by the increased temperature of the electrode during the light emission of the discharge process. They will be attracted by virtue of the magnetic field and adsorbed under magnet so that these particles or substances will not be able to settle on the inside of the bulb.

Title: Spreading of photoresist emulsion over plate - includes application from array of nozzles followed by plate spinning
Inventor: SATO MASAMICHI
IPC: G03C1/74
Filed: 1977-10-17
Abstract: Till now, a blob of the emulsion has been put in the centre of the plate, and spread entirely by spinning the plate. This has proved unsatisfactory with the larger plates, and with certain emulsions. To avoid this problem the emulsion is first spread over the whole plate, and only then is the plate spun, to produce a uniform layer of the required thickness. The first operation may be done with a manual spreader, or automatically with either a two-dimensional array of nozzles, or a line of nozzles moving relative to the plate, or a single nozzle whose relative motion is a meandering path. If used in a group, the nozzles would typically be spaced at 5-30 mm.

Title: Vacuum cooling of salt solutions in crystalliser - using steam ejectors to remove and re-compress water vapour which is then condensed in surface condenser
Inventor: EBNER KARL
IPC: B01D9/00
Filed: 1977-11-08
Abstract: Aqueous salt solns. are cooled by a vacuum technique using steam ejectors to extract the vapour at low pressure. The water vapour extracted is simultaneously compressed in the ejector and finally condensed in a surface condenser. The condenser is cooled by brine or can be directly cooled by refrigerant. In the latter case, the condenser serves as the evaporator for the refrigeration circuit. For use in cooling crystalliser solns. to produce crystals. Vacuum cooling is generally limited to 5 degrees C because of difficulties in condensing the water vapour drawn off. The system described overcomes this by compressing the vapour and allowing it to be condensed at a higher temp.
