Abstract: PATENT APPLICATION for IMPROVED PROCESS FOR PRODUCING   ALKALI METAL POLYSILICATES   by Orlando L. Bertorelli ABSTRACT OF THE DISCLOSURE     An improved method for producing alkalimetal polysili-cates is disclosed.  The polysilicates are produced by hydro-thermally reacting an aqueous dispersion of finely-divided silica and an alkali metal hydroxide.  The synthesized reaction mixture is then spray dried with the solid product then being fractured and pulverized.  The fractured particles are thereafter pelletized and dried in a fluidized bed to produce a product having pre-determined characteristics or properties.  The product can be used in adhesives, in the production of silica gel, in textiles and the like.  However, their use as builders in detergents and in combination with known anionic, nonionic and amphoteric surface active compounds (surfactants) is disclosed as being particularly advantageous.

Abstract: HIGH PRESSURE SAMPLE INJECTOR AND         INJECTION METHOD                        Abstract of the Disclosure An injection apparatus and method for use in high pressure Liquid chromatography.  A cylindrical sample holding means con-taining several sample cells is maintained in a chamber whose pressure is approximately equal to that of the head of the  chromatograph separation column.  The sample cells are bores through the cylinder, parallel to its axis and spaced along a cylinder of revolution concentric to the axis.  The cells are preloaded with samples to be analyzed.  Stationary carrier fluid inlet and outlet conduits extend into the chamber above and below corresponding points on the cylinder defined by the sample cell placement.  The inlet conduit is connected to a high pressure source of carrier fluid.  As the sample holder is rotated, successive sample cells are aligned with the inlet and outlet conduits such that the sample is forced through the outlet conduit into the column. This struc-ture eliminates the need for movable high pressure seals between the outlet conduit and the sample cells, due to the maintenance of all the cells at an elevated pressure.

Abstract: ABSTRACT OF THE DISCLOSURE         A dispensing device for flowable material comprises a rigid tubular housing having a dispensing outlet at one end and a relatively rotatable end cap.  A flexible container for the flowable material is made of high tensile essentially non-stretchable material and is located in the housing with one end in communication with the outlet.  The other end is connected to the end cap so that rotation of the end cap twists the end of the container to dispense the flowable material. The connection is through a compensating  device which, while transmitting the rotation of the end cap, allows the twisted end of the container to move axially in an essentially non-resilient manner but offers sufficient resistance to keep the twisted end along the axis of the housing.

Abstract: ABSTRACT OF THE DISCLOSURE :          The disclosure is directed to a hand tool of the pliers configuration having a set of crimping nests located in jaw members and having the expansion zones of the crimp-ing nests overlap so as to permit placement of each of the nests closer to the optimum distance from the handle pivot.          A visual indicator permits the operator to crimp terminals of different discrete sizes in a single one of the crimping nests and a hook member used to lock the handles in a closed position further provides discrete limits of crimping nest closure.  A compression spring located in overlapping slots of the handle member provides a recessed means to rapidly open the handles when the hook member is released.  Discretely sized insulation cutting edges located between the pivot and the handle free ends permits the edges to overlap one another and thus provide a complete cut about the wire periphery and provide a wedge to break through the uncut land of insulation.
