Abstract: ABSTRACT:            The invention relates to a syringe for injecting two or more injection liquids which may not be in contact with each other for a longer period of time, comprising a barrel having a piston, a needle on the front side of the barrel, a sealing stopper in the barrel on the front, and one or more separating stoppers which, before use of the syringe, keep the injection liquids separated from each other. The needle is connected to the front of the barrel by means of a needle holder comprising a collar to connect the needle hol-der to the barrel, a neck to connect the injection needle, and a hollow shaft between collar and neck, in which a passage is formed in the inner wall of the shaft and the rear face of the neck, past which passage the injection liquids can reach the cannula when during use of the syringe the stoppers are moved into the shaft of the needle holder.

Abstract: Abstract Multi-Component Grouting System A multi-component grouting system having at least one component wherein the active ingredient is contained in the dispersed phase of a water-in oil emulsion, the oil providing an effective barrier against mixing of the components thereby enabling the components to be stored indefinitely in direct contact.  The components may advantageously be encapsulated in a single compartment frangible casing for insertion into drillholes in rock. The grouting systems may be based on compositions comprising hardenable resins, Portland cement, Plaster of Paris, zinc oxide/zinc chloride, or sodium silicate.    By eliminating the usual plastics film barrier between the grouting system components, intimate mixing of the components in a drillhole by rotation of the bolt to be fixed in the drillhole may be more easily and reliably effected.

Abstract: Abstract A unique method and apparatus for efficiently assigning duplex radio channels and scanning duplex radio channels assigned to mobile and portable radiotelephones in a cellular communications system is described.  Each cell includes a base station radio having a signalling channel and a plurality of voice channels, and a base site controller adapted to utilize the methods embodying the present invention for controlling communications paths to mobile and portable radiotelephones.  The base station radios include a signalling transceiver operable on the signalling channel, a plurality of voice transceivers each operable on a voice channel, and a scanning receiver for sampling the signal strength of active radiotelephones.  Transmitters of the signalling transceivers and voice transceivers are combined and coupled to an omnidirectional antenna; and the receivers of the signalling transceiver, voice transceivers and scanning receiver are couplable to one or more of six sector antennas.  In practicing the methods of the present invention, the microprocessor controlled base site controller maintains high quality communications paths to mobile and portable radiotelephones by periodically monitoring their signal strength and when signal strength degradations are detected, either changing the base station sector antennas coupled to voice transceivers, increasing or decreasing radiotelephone power output, or handing radiotelephones off to another cell.

Abstract: ABSTRACT OF THE DISCLOSURE         A process is described for the formation of high purity alumina from Bayer Process alumina trihydrate (gibbsite).  The solid hydrated alumina is reacted with concentrated HCl to cause partial or complete conversion to aluminum chloride hexahydrate (ACH).  The ACH or mixture of ACH and unreacted hydrated alumina is recovered as a solid and calcined in a single or multistage calcination to high purity alumina.  Soda contents in the product. anhydrous alumina can be reduced by 98% or greater.  Contents of other impurities, such as silica, iron, magnesium, etc., are also markedly reduced.          Different degrees of impurity reduction can be obtained by controlling the degree of conversion of the hydrated alumina to ACH and by recycling and treating the acid after solid/liquid separation.  The purified products find use in the specialty ceramics field, as catalyst supports, as absorbents, in electronic components, in prosthetic devices or other applications in which alumina of controlled degrees of purity offers an advantage.
