Abstract: A b s t r a c t In the causticization part of the sulphate process the conductivity of the green liquor and the white liquor is measured, and the specific gravity of the green liquor is measured to determine the TTA-value (total titratable alkali).   The measuring values are  registered on-line in a data processor calculating the required change of the supply of burnt lime or green liquor to the slaker and/or the required change of the TTA-value of the green liquor for the control of the properties of the white liquor.  The measurings carried out provide the basis of a control of the properties or composition of the white liquor, whereby the causticization process  forming part of the sulphate process is simplified and made more effi-cient. The drawbacks associated with an insufficient  con-trol, e.g. calcification and the consequent poorer filtrat-ability  of the white liquor as well  as a too high content of calcium in the white liquor, cause calcification  of filters, pipes, pumps, and digesters etc. An efficient control of the properties or composition of the white liquor facilitates the preparation of pulping liquor to be used in the sulphate process, and an efficient use of the raw materials necessary for carrying out the process is thereby obtained.

Abstract: ABSTRACT OF THE DISCLOSURE           A nozzle is provided which automatically closes the flow when the tank is almost full.  This arrangement prevents overfilling the tank of a small internal combustion engine.  The nozzle is put on the fuel container which communicates with the surroundings by an air conduit through the nozzle.  The nozzle is constituted by two sleeves, an outer one and an inner one, with a threaded bushing to enable connection to a container.  The fuel passes through the inner sleeve, whose outer end has a valve body.  When the outer sleeve is at rest, it presses against the body, and then the nozzle is closed.  When the nozzle is put into a tank filling hole, the spring-biased outer sleeve is pushed back and allows the fuel to pass through the inner sleeve to the tank.  When the fuel reaches the outer end of the nozzle the air inlet to the container is closed and the fuel flow stops.  When the nozzle is pulled out of the hole it is automatically reset into the rest position.

Abstract: HOME DIAGNOSTIC AID AND       METHOD FOR DETERMINING THE PRESENCE OF OCCULT BLOOD                  FOR USE BY THE GENERAL PUBLIC                    Abstract A guaiac reagent-based diagnostic aid for determining the presence of occult blood in an aqueous system contains a micron-sized silica gel into which a guaiac solution has been adsorbed. The guaiac-containing carrier is contacted with a dry, particulate, oxidizing agent, such as a monopersulfate compound, to form a single composition. This composition can be packaged in a water-pervious sandwich. Upon contact with water, the oxidizing agent is activated to produce hydrogen peroxide, which in the presence of occult blood will oxidize the adsorbed guaiac to a brilliant blue reaction product.

Abstract: MASS TRANSFER CONTACT APPARATUS                        ABSTRACT    There is disclosed an improved mass transfer or gas-liquid contact device having a specially contoured grid member(s) interposed in the gas flow of the device.  Ideally the grid member(s) has a cross-sectional profile which equals the sum of the theoretical velocity pressure profile of the gas flowing in an open vessel and the static and dynamic heads of the contacting liquid.  An additional depth is added to the grid approximately 5 to 40% more, to create an energy imbalance in favor of the introduced liquid, thereby allowing it to drain. In existing vessels where it is desirable to replace prior art devices with an apparatus embodying the present invention, a plurality of grid modules may be employed, each module including a shaped grid or grid pair approximating the velocity profile of the gas stream in each.

Abstract: MINIATURE PLUG-IN FUSE AND METHOD OF MAKING SAME       ABSTRACT         A method of making a miniature plug-in fuse starts with a strip or sheet of conductive metal of uniform thickness.          A basically U-shaped preform is stamped from the sheet having a pair of spaced parallel legs connected at least one end by a bridge which will constitute the fusible member.  The legs are each then folded upon themselves to provide plug-in con-tacts of at least twice the thickness and stiffness of the starting material.  Finally, the preform is partially encapsu-lated in an insulating resin leaving the end portion of the contacts exposed but enclosing the upper ends of the legs and forming a handle by means of which the fuse may be inserted and removed from a mating socket.  A window is also formed in the resin aligned with the bridge to permit easy visual deter-mination of the continuity of the fusible member and spaced notches are formed in the upper surface of the resin exposing the legs on opposite sides of the bridge to permit electrical continuity testing of the fuse.

Abstract: ABSTRACT     A mechanically  rigid  joint  is  formed  between  two  different metals by completing the joint in a forging operation.  A part (14) made of one metal is placed in a die form (20) and is maintained at a temperature below that required for forging.  A billet (23) made of the material from which the second part (13) is to be formed is placed in the die (20) so that the billet (23) can be formed into the second part (13), engaging the first part (14) at an interface (16) defining the joint.  The joined parts (13, 14)  are then machined into their final shape.  The joint (16) is stabilized by maintaining appropriate temperatures  of  the  materials  to  compensate  for  expansion  and contraction after forging, and by providing suitable coatings for the materials, particularly at the interface (16).      Advantages include reduction in weight and increased stability of  a  final  assembled  component  because  the  two  parts  are  joined without the use of fasteners or other conventional techniques.

Abstract: ABSTRACT OF THE DISCLOSURE     An electrical assembly, for example for use in low voltage supply distribution, comprises a fixed casing for each of three phases.  A pair of fixed contacts are spaced apart within the casing and set back from an opening into the casing.  A fuse carrier is mounted for rectilinear sliding movement within the casing between a first position adjacent to the opening and a second position.  In the second position movable contacts on the carrier engage the fixed contacts to close a circuit therebetween.  A drive unit is provided for mechanically driving the carrier between the two positions, the drive unit being a self-contained mechanism comprising a housing and a drive member movable relative thereto.  The drive member can be detachably coupled to the contact carrier, and means provided for releasably locking the drive housing to the fixed casing.  Thus, the drive unit is a separate entity from the contact assembly and can be used as required to drive any selected contact carrier.
