Abstract: Abstract of the Disclosure The invention is a flash-drying process in which a solvent solution of a polymer or copolymer at an elevated temperature and pressure is introduced into a flashing zone maintained at a pressure lower than the pressure of the solvent solution through a means for releasing said elevated pressure, so that evaporation of solvent and separation from the solution occurs.  A feature of the process is that an inert stripping agent is fed into the flow of solvent solution at any point between the pressure-releasing means and the flashing zone.  Hence the rate of solvent removal is increased but is not accompanied by problems such as thermal degradation or gellation of the polymer or copoly-mer.

Abstract: LINEAR ACTUATOR               ABSTRACT OF THE DISCLOSURE           A linear actuator for providing a thrust force for actuating various movable members, such as, for example lever arms, crank slides and valve flaps.  The thrust force is applied by an extension rod that is arranged within a housing so as to extend in an axial direction along the housing and out from the housing.  The extension rod has a load connector mounted on the end outside of the housing for connection to the movable member to which the thrust force is to be applied.  A drive screw is attached to the extension rod so that rotation of the drive screw is translated into an axial displacement of the extension rod. A drive motor serves to rotate the drive screw.      While the extent of displacement of the extension rod can be controlled by a limit switch mechanism, a blockage in the path of the movement of the movable member will prohibit the movement of the movable member and the extension rod.  Either when such a blockage occurs of when the extension rod has reached the end of its path of travel, any attempt for continued movement of the extension rod significantly increases the thrust force applied to the rod.  In order to prevent the continued application of such force and resulting damage to the system, a thrust control mechanism is provided for terminating operation of the drive motor when the thrust force exceeds selected thrust force limits.  The thrust control mechanism includes an adjustable device for enabling the thrust force limits to be selectively adjusted.  Such adjustments for selecting the limits of the thrust force can be made without requiring disassembly or any adjustment to the major working mechanism of the linear actuator.

Abstract: ABSTRACT OF THE DISCLOSURE     A jointer for smoothing mortar joints has an elongate handle and offset trowel portion at each end.  Each trowel portion is shaped to gradually decrease in width toward its free end and is convexly curved to enable the use of one tool for a number of joints of different width.  One trowel portion is shorter than the other to improve the convenience in compact-ing head joints.  Both blades are offset to the same side of a centerline of elongation of the handle.  The tool provides a simple and inexpensive improvement by rendering the tool suitable for different widths of the joint while also improving the convenience of working with the tool.

Abstract: ABSTRACT OF THE DISCLOSURE    The present invention provides a concentrated aqueous composition of metal aldonate and/or ammonium aldonate.  Part of the aldonate is present in the dissolved and part of it in the suspended state.  It is preferred that the aldonate should be sodium gluconate.  The composition should contain a colloidally dissolved gum as suspending agent.  Very suit-able for this purpose are carboxyl groups containing gums, especially xanthan gum.  In this manner, stable compositions having a high aldonate content can be obtained.  The present compositions may be used for many purposes, for instance in the processes of cleaning bottles, metal surfaces, etch-ing of aluminium and in certain galvanizing processes, in the tanning of leather, in paper making and in the treat-ment of textiles, in removing paint, as a diluent in drilling fluids, in working up cement and gypsum, in fixing baths applied in photography, as a carrier of metals in agricul-ture and for pharmaceutical purposes.  The compositions according to the invention stand freeze-thaw cycles without being adversely affected.  In the above-mentioned solutions crystallization takes place at low temperature (-10°C). Consequently, thawing is not automatically followed by re-obtaining a stable solution.  Moreover, after thawing and during renewed preparation of solutions it should be taken care that invariably the same concentration is obtained. Further, as compared with the corresponding solutions the present solutions have a higher aldonate content per unit volume.  This is of advantage with respect to transport and storage.
