Abstract: A B S T R A C T          The invention relates to a method in the gasification of sulphur--containing carbonaceous material using metal smelts. When gasifying such carbonaceous material in a metal smelt, the material is intro-duced to a gasifying reactor containing an iron and/or manganese smelt having a temperature of between 1109 and 1600°C, suitably 1150 - 1250°C, the smelt being substantially saturated with respect to sulphur and carbon. The carbonaceous material is oxidized to carbon monoxide and the sulphur content forms a matte phase contain-ing a high percentage of sulphur, which phase is tapped off. Residual non-combustible material is collected as a slag on the surface and is removed together therewith. If so desired, the matte can be gran-ulated and roasted to recover the sulphur and metal contents. Carbon-aceous material incorporating pyrolysible constituents is suitably pyrolysed in a pyrolysis medium at a temperature of between 450 -800°C prior to the gasification reaction, the temperature during the pyrolysis process being maintained, by circulating the pyrolysis medium between pyrolysis and gasification and optional combustion of carbon monoxide has formed.

Abstract: INVENTORS:  IMRE BAJKA and ROBERT FURRER            INVENTION: METHOD AND APPARATUS FOR REMOVING SOLDER FROM             THE DRILL HOLES OF EMPTY PRINTED CIRCUIT BOARDS COATED WITH SOLDER     ABSTRACT OF THE DISCLOSURE     During the pre-soldering of printed circuit boards, as a rule, also the drill holes or bores and, in particular, the  through-metallized  drill  holes  are  filled  in  an undesirable manner with solder.  This solder must be removed before mounting the electrical components or elements upon the printed circuit boards.  A simple method is disclosed for this purpose, affording a faultless de-soldering of the drill holes, without deleteriously affecting the properties of the solder material.  The printed circuit boards, in a condition where the solder applied during the pre-soldering operation is still molten, are accelerated at least once and thereafter suddenly brought to standstill in such a fashion that the excess solder is knocked or propelled out of the drill holes.  The apparatus for accomplishing the method contemplates guiding the printed circuit board essentially horizontally  in a frame and accelerating  such printed circuit board in a guided vertical drop or fall in the direction of an impact location, so that upon concussion of the frame at  the impact location the excess solder  is downwardly knocked or propelled out.

Abstract: "GROUND WORKING IMPLEMENTS AND WING FOLD MECHANISM THEREFORE"         ABSTRACT OF THE DISCLOSURE           Conventionally, double fold mechanism for sections of ground working implements such as cultivators, plows or the like utilize a hydraulic piston and cylinder assembly to lift one wing section to approximately 90° , and then to lower it over the other center or wing section so that it lies either at an angle to the horizontal or substantially horizontally above the center or other section.  Also re-quired is freedom of the wing sections to "float" during field use to allow for uneven ground.  This "float" is usual-ly provided for by means of a slotted link connection be-ween the two sections but this slotted link connection allows a period of free fall as the elevating section passes over top dead center or through the center of gravity, when moving in either direction, thus causing relatively high impact loads to the linkage and supporting structure because of the weight of the moving section.  The present device utilizes a slotted linkage but also includes a spring load-ed pin within the slots of the links.  As the section is moving towards the substantially vertical or top dead center position, the spring forces the pin to the far end of the slot just prior to the wing section passing over top dead center and this takes up the free movement and prevents any free fall from occurring.  The spring loaded pin and slots also allow a cushioned floating action when the implement is in the field working position.

Abstract: Title of the Invention SOLID FUEL HOT WATER HEATER          Abstract of the Disclosure A solid fuel burning hot water heater is described having a primary combustion chamber with a refractory material base portion which forms the locus of combustion.  A water jacket defines an upright portion over the refractory base portion for receiving a charge of fuel in a generally vertical stack.  The water jacket is coupled to a source of water for at least convection circulation and assists in confining the locus of solid fuel combustion to the base of the chamber.  Heat exchange channels or pathways are defined around the outer periphery of the water jacket in heat exchange relationship with the water jacket for transfer of heat from the end products of combustion to the circulating water.  A flue gas delay channel arrangement extends from the draft outlet at the base of the combustion chamber to the heat exchange pathways.  The delay channel pathways provide delayed propagation of gaseous products of primary combustion in a high temperature refractory environment sufficient to afford substantially complete secondary burning.  In the preferred configuration the flue gas delay channel provides pathways coaxially around the walls of the  refractory base portion of the primary combustion chamber while the heat exchange pathways are formed coaxially around the water jacket.          An opening is  formed between the flue gas delay channel pathways and the heat exchange channel pathways. The refractory base portion walls of the primary combustion chamber may be formed in a "U" shaped or arcuate configuration.

Abstract: ABSTRACT      A container for delivery and/or collection of a fluid, in particular a liquid. The container comprises an observation marking which is adapted so as to show up in accordance with variations in the fluid level     in the container     for rapid indication of the quantity of fluid present at any given instant of observa-tion.    The observation marking     preferably comprises a first pat-tern     arranged on one side     of the container and a second pattern     arranged on the other side     of the container, the said first and second patterns being adapted so that by combined action with one another they give rise to a third clearly discer-nible pattern     in a direction of observation from the said other side     of the container on observation levels above the liquid level      in the container.    The container     is manufactured appropriately from a flexible material, for example plastics, in the shape of a bag with at least one inlet     communicating with the interior of the bag.        As a result of this the material properties of the bag can be uti-lized for a clearer showing up of the third pattern    , since the two sides        of the bag will be sucked towards each other owing to the vacuum which is produced in the empty space above the falling liquid level .    A reading scale      adapted to the quantity of enclosed liquid may be arranged, for example, in association with the observation marking , so that the observation marking can be made use of also as a means for facilitating the accurate reading of this scale in that the observation marking clearly indicates the intersection between the liquid level         and the reading scale  .

Abstract: ABSTRACT OF THE DISCLOSURE    The invention relates to a system of stretching overhead electric lines, more particularly high-tension lines, according to which a pilot cord or haulage cable is positioned in conventional manner over a set of top pulleys positioned at the highest point on each pylon in the line, and is then used to pull a first haulage cable or guard cable together with at least one other supplementary haulage cable, and/or supplementary guard cable. Each supplementary cable, after pass-ing the top pulleys on which the first haulage cable or guard cable have been laid, is slid and guided downwards until it rests on pulleys underneath. In this manner, each further haulage cable is already positioned for drawing a conductor or bunch of conductors and other haulage cables if required. In the aforementioned system, it is no longer necessary to position a pilot cord for each conductor or bunch of conductors to be tensioned, but it is sufficient to position a single pilot cord on the top pulleys of the pylons, since all the conductors or bundles of conductors and/or further haulage cables are subsequently positioned automatically, starting from the pilot cord or first haulage cable, during the subsequent stage of tensioning.

Abstract: DIFFERENTIAL PRESSURE VORTEX SENSOR     ABSTRACT OF THE DISCLOSURE A differential pressure sensor      adapted specifically for use with vortex shedding flowmeters which can be used in small spaces, uses a bending beam for providing an electrical signal proportional to differential pressures between two oppositely facing diaphragms           .  The diaphragms deflect under differential pressure and cause the beam      to be bent.  The diaphragms            have low mass and have a support structure      between them, carrying spring clips      which load one end of the bending beam     .  The other end of the bending beam      is then supported so it cantilevers from its mounting or support  and upon movement of the diaphragms            under differential pressure the beam     will bend.  The signal can be derived by using a bending element made of a piezoelectric "bimorph" beam, which provides a voltage output as it bends, a strain gauge sensor on the beam, or an optical sensor, such as a fine fiber which deflects and provides an optical output, may be used, as well as similar devices.  Preferably, the sensor is a piezoelectric bimorph beam because of the direct electrical signals provided, which result from bending of the beam    .
