Filed: 1988-09-02
Abstract: The invention is a process of selective and quantitatively removing and concentrating at least one selected ion present in low concentration with other ions in higher concentration in a multiple ion solution. The method comprises bringing a complexing agent for the selected ion(s) into contact with a sufficient determined quantity of said multiple ion solution to remove and concentrate the selected ion(s) from the multiple ion solution; removing the multiple ion solution, from which the complexing agent has removed the selected ions, from the complexing agent having the selected ion(s) complexed therewith, bringing the complexing agent complexed with selected ion(s) into contact with a determined quantity of receiving liquid to break the complex and remove the selected and concentrated ion(s) from the complexing agent and determining the concentration of selected ion(s) in the said receiving liquid from which the concentration of selected ion(s) in the multiple ion solution can be calculated. The metal ions in low concentration are often heavy metal ions, such as lead ions, and the process finds particularly advantageous utility in the determination of lead content in ppb in drinking water. 
     The preferred apparatus for carrying out the process is a column packed with silica gel or silica-­bonded macrocycle as the complexing agent.

Title: Ground engaging surface for endless tracks and wheels.
Inventor: BURNS ALAN ROBERT
IPC: B60B9/10
Filed: 1988-01-29
Abstract: A ground engaging segment providing a running surface for wheels, endless tracks and the like, which is not pneumatic in nature, thereby not susceptible to puncture, and which is resiliently flexible to offer some resistance to shock. The ground engaging segment comprises a base and a number of removable, hollow, tubular ground engaging elements which extend transversely of the direction of travel of the running surface. Said ground engaging elements include an inner face for engagement to the base and an outer face for contact with the ground surface, and angular shaped side faces between the inner and outer faces allowing for resilient flexibility under normal load conditions. It is preferable that the ground engaging elements are open at their ends to allow for dissipation of heat and are arranged in circumferential rows, defining a chevron pattern, to prevent resultant side thrust imposed upon the running surface. In addition, the ground engaging elements are constructed angularly to provide a line about which the side faces can flex, and include a flexible internal reinforcement, built in to the walls of the faces of the ground engaging element to provide reinforcement for the ground engaging element, while maintaining flexibility.

Filed: 1988-08-26
Abstract: A beverage brewing machine which has upper (11) and lower (25) brewing chambers which are moveable relative to each other so as to clamp a strip-shaped filter (36) therebetween during the brewing process and the chambers can be separated so as to allow the filter strip to be removed from the brewing chamber and the beverage residual wiped therefrom after which the filter strip is returned to the brewing chambers which are then resealed for the next cycle. A hold down grid (20) engages the top surface of the filter (36) to hold it down as a piston (26) moves in the lower chamber (25) upwardly to force air through the filter to agitate the beverage. When the piston reaches top dead center, the hold down grid (20) is lifted. When the piston passes the opening the brewed coffee is poured. A loose connection is provided between the connecting rod for the piston and the driving crank arm so that the piston remains longer at the top and bottom of its stroke. Due to agitation of ground and oxygenation of the mixture, or a combination of both, by adding a high volume of air during the brewing process, increased extraction results. <IMAGE>

Abstract: The invention relates to a method for the preparation of transparent metal oxide pigment, in which a substan­tial portion of the silicon oxide is dissolved off from silicon dioxide based particles coated with transpa­rent metal oxide, and to a transparent metal oxide pig­ment prepared by the method. In the extraction methods according to the prior art the problem is that in the extraction a part of the metal oxide is also dissolved, whereby thickness variations impairing the interference color of the metal oxide layer are created. Moreover, in the known methods hard-treated extraction chemicals which are detrimental for the environment are used. These problems have by means of the present invention been solved so that such particles are selected for the dissolution whose silicon dioxide portion is substan­tially soluble in base and metal oxide portion is subs­tantially insoluble in base, and the dissolution is carried out by base. The silicon dioxide based particles can be selected from the from the beginning base-soluble particles or they can be made base-soluble by extracting them with mineral acid. The shape of the metal oxide particles obtained through base extraction corresponds fragmentarily to the form of the outer sur­face of the silicon dioxide based particles and they are in the form of single closed sheets or flakes.
