Abstract: ABSTRACT            A method of highly efficiently separating preferably low contents of gaseous mercury from a gas mixture, where the gas mixture is caused to contact a solid sorbent consisting of powdered calcium hydroxide, which in an atmosphere containing hydrogen chloride is to a certain part converted to calcium chloride. The temperature of the gas mixture is between 80°C. and 280°C. The contact between the gas and the sorbent preferably takes place in a fluidized bed, whereafter the sorbent is separated in a dust separator. The method is suitable for use at the separation of mercury occurring in flue gases, for example from refuse incin-erators or in mercury-containing gases from process industries.          At experiments with flue gas from a refuse incinerator the mercury content was reduced from 200 to 5µg of gaseous mercury/cubic metre flue gas.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention provides a method of converting con-ventional weaving looms, which includes filling components, pick motion components, parallel motion components, filling motion components and lay motion components.  The method com-prises the steps of removing from a conventional apparatus the filling system, the pick motion components, the parallel motion components, the filling motion components and the lay motion components and mounting to the apparatus a liquid jet system.  The liquid jet system comprises means for advancing a weft filament across warp filaments comprising a source of pressurized liquid, nozzle means for projecting the source of pressurized liquid in a stream across the shed, means for supplying a length of weft filament having a free leading end and in operative relationship to the source of pressurized liquid, whereby the stream of pressurized liquid is adapted to engage the leading end of the filament.  There is further provided means for actuating the source of pressurized liquid to provide a predetermined amount of pressurized liquid in the form of a stream directed across a shed, and means for inter-rupting the flow of the stream of pressurized liquid before the weft filament traverses the width of the shed, providing a storage chamber for the weft filament, and providing means for operating the liquid jet system in conjunction with the modified loom.  The invention overcomes the necessity of purchasing new equipment since a conventional loom can be converted to a fluid jet loom.

Abstract: STERILIZED STORAGE CONTAINER           Abstract A container lid (12) is held open by a support plate (18) carrying a chamber (20) which expands at a predetermined point in a sterilizing cycle to react against the lid, moving the plate outwardly to permit the lid to drop onto the container base. A resilient gasket (16) prevents fluid flow into the container after the lid is fallen, but permits fluid flow outwardly past the gasket when interior pressure  exceeds exterior pressure.  When the container is to be opened, a relief valve (60) relieves the vacuum within the container and filters air entering the container at that time.

A first conductive member is connected to the N-type material of the first zone and the silicide layer of the third zone.  A second conductive member is connected to the N-type material of the second zone and the silicide layer of the fourth zone.  A third conductive member is connected in common to the silicide layers on the first and second zones. A fourth conductive member is connected to the N-type material of the third and fourth zones.  An AC voltage applied across the first and second conductive members produces a DC voltage across the third and fourth con-ductive members.

Abstract: ABSTRACT OF THE DISCLOSURE In the case of drive units, more particularly for ships, comprising a hollow driving pinion located axially between a hydraulic coupling and a con-trollable bypass coupling for selectively bypassing the hydraulic coupling, stresses may arise, for example as a result of misalignment, but also as a re-sult of changes in the foundations arising during operation.  Such stresses are difficult to avoid because appropriate bearing locations are required to support individual components of the drive, for example the actual transmission, but also the drive shaft between the hydraulic coupling and the power plant.  According to the invention, these stresses may be eliminated simultaneously, in all types of transmission, by arranging, between the power plant and a support bearing in front of the hydraulic coupling, a universal coupling designed to permit radial, axial and angular misalignment between the drive shaft and the power plant drive shaft.

Abstract: Abstract:    A laser beam scanning system is designed for focusing a laser beam to a fine spot and for precisely scanning a large field.  The system has an acousto-optical deflector that can deflect a laser beam in the direction of one axis or in the directions of two axes, while maintaining the fine spot diameter, in order to scan a small field. A relay lens projects this deflection point to the center of an objective lens.  The objective lens can effect focus-ing to the fine spot.  A high speed, accurate carriage can move in the biaxial directions.  A precise position detector detects the position of said carriage, and a controller controls the various functions whereby to make it possible to precisely deflect the laser beam over a large field.  As a result a scanning operation over a large field at high speed and with high accuracy can be performed by the laser beam.

Abstract: Keefer 16 c/w REVERSE OSMOSIS METHOD AND APPARATUS     ABSTRACT OF THE DISCLOSURE             Reverse osmosis, particularly for water desal-ination, is achieved using semipermeable membranes which selectively permeate purified water from a feed solution pressurized by reciprocating piston or diaphragm pump. Pump action is assisted by returning pressurized concentrate fluid acting on reverse side of the pump piston or dia-phragm.  Directional valves controlling alternating admis-sion and venting of concentrate fluid to and from pump cylinder are actuated mechanically by reversal of force applied to the piston rod.  Mechanical dwell is provided in the piston or diaphragm motion during directional valve actuation.  Pump may be operated by a manual lever or by a crank mechanism on a low speed rotary shaft.  An optional differential surge absorber provides continuity of feed solution circulation past membrane surfaces during the return pump stroke, thus minimizing detrimental salt concen-tration build-up on the membranes.
