Title: Surgical irrigator for body cavities
Inventor: MOVSHOVITZ AVNER
IPC: A61M3/02
Filed: 1985-11-22
Abstract: A device for forcing liquid treatment material into a human body cavity comprises: a curved housing (12) to be held in a hand, having a rear inlet (14) connected to a tube for attachment to a source of water, and leading into a bore (18, 22, 25) within the housing and thence through the body to an outlet (28) at a reduced cross-section front end of the body; a chamber (56) for holding treatment material and a piston (70) to force the treatment material from the chamber into the flowpath (27) via orifice (66). A transverse bore (20) which is present in a hydraulic switch permits some of the water flow to be diverted, if desired, along a parallel flowpath to an annular space (72) behind a piston (70) in a chamber (56) in the front end; thus forcing the piston forward, and a treatment material, e.g. a viscous liquid, present in the chamber is then progressively drawn out of the chamber through a restricted aperture (66) into a narrow final portion (27) of the water flowpath. The treatment material is thus supplied at a rate proportional to the rate of flow of the water. <IMAGE>

Title: Method and apparatus for maintaining fluid-gas dispersions
Inventor: VELEBIL GERHARD
IPC: C02F3/12
Filed: 1986-10-08
Abstract: To maintain a fluid-gas dispersion in a vertical receptacle 2, which contains a substrate such as effluent, sewage or the like to be treated with gas, an upward-directed more or less helical turbulent flow of the fluid-gas dispersion is produced in receptacle 2, so that the flow path is substantially increased compared with the height of receptacle 2 and thus the dwell time of the gas in substrate 3 is appropriately extended. This may be achieved in that inlet or inlets 4 and 5 for the gas-fluid dispersion is/are arranged eccentrically in the bottom area of the receptacle near its bottom 6. <IMAGE>
Patent GB-2182262-A (GB)
Title: Oxygen containing silicon substrates
Inventor: SUZUKI TOSHIHIKO
IPC: C30B15/30
Filed: 1986-10-31
Abstract: A method for producing silicon substrates includes growing the silicon crystal body at a relatively high rate of growth. It has been found that the growth rate of the silicon crystal body exerts substantial influence upon generation of crystal defects in the silicon crystal body or silicon substrate. Furthermore, the oxygen concentration in the silicon crystal body or the silicon substrate is significantly higher than in conventional silicon crystals or substrates. The high growth rate of the silicon crystal body suppresses separation of the oxygen from the crystal body. This reduces the number of defects or faults formed in the crystal body during heat treatment during production of the semiconductor devices. In the preferred process, according to the present invention, the growth rate of the silicon crystal body is greater than or equal to 1.2 mm/min. Furthermore, the preferred oxygen concentration in the grown silicon crystal body is selected to be greater than or equal to 1.8 x 10<18> cm<-3>. <IMAGE>

Patent GB-2210809-A (GB)
Title: Scrubber-exhaust gas conditioner
Inventor: OLAVSON LARS G
IPC: B01D50/00
Filed: 1988-09-26
Abstract: A conditioner for cooling and cleaning hot exhaust gas containing particulates has an enclosure partially filled with liquid and a gas conditioning means positioned within the enclosure. Hot exhaust gas entering the conditioning means passes through a liquid induction portion submerged in the liquid to introduce a portion of the liquid into the hot gas stream within the gas conditioner means to form a gas-liquid mixture. The hot exhaust gas-liquid mixture then flows through a contact portion of the conditioning means in which cooling of the hot exhaust gas takes place through vaporization of at least a portion of the liquid. The cooled exhaust gas-liquid mixture is then passed through a separator portion of the conditioning means in which the direction of the flow of the cooled exhaust gas-liquid mixture is changed. Separation of the cooled exhaust gas from at least a portion of the liquid and particulates occurs through a centrifugal action of the mixture within the separator portion of the conditioning means. The liquid and particulates removed from the cooled exhaust gas return to the pool of liquid within the enclosure. The cleaned and cooled exhaust gas impinges on a barrier type separator to remove additional liquid entrained in the cooled exhaust gas. The cooled exhaust gas then passes through an outlet opening in the enclosure to the atmosphere.

Title: Venetian blinds and methods of manufacture.
Inventor: VAN DER ZANDEN GEORGE CHRISTIA
IPC: E06B9/308
Filed: 1989-08-25
Abstract: The specification discloses a method of assembling two different venetian blinds having two different slat widths, the flexible elements 14, 16 of a ladder means of which are each mounted on a tilt roll 10, the flexible element of each pair extending down the different opposite lateral outermost points 18, 20 of the tilt roll 10. Identical tilt rolls are utilized for the ladder means of the blinds of first and second widths. The flexible elements of each ladder means of the blind of slats of lesser width are attached to the respective tilt rolls 10 (Figure 1A), so that they extend directly from the securing means 12 of the tilt roll to the laterally outermost points 18, 20 of the roll 10. The flexible elements of each ladder means for the blind with the slats of greater width are attached to the respective tilt roll 10 , so that each of the flexible elements 14, 16 of each pair extends from the securing means 12 of the tilt roll 10 around at least half of the periphery of that tilt roll to reach the laterally outermost points 18, 20 of that roll when the blind is in its fully opened position. Thus the tilt roll must be rotated a greater distance for the blind of greater slat width than for that of the lesser slat width to give a given angle of tilt.
