Abstract: ABSTRACT      Attachments are described for enabling small front wheels of wheelchairs to negotiate side-walk kerbs or the like.  An arcuate rocker end for engaging the kerb is fixed to a strut pivoted above the wheel and held in a ready position, determined by engaging abutments, by a prestressed, i.e. strained, spring which is further strained when the rocker end engages a kerb and the advancing wheelchair causes the strut to swing backwards lifting the wheel onto the side-walk, whereupon, the rocker end is free to return to the ready position.  The rocker end may be manually shifted to an idle position in which it is firmly held by the spring.  In one example, one of the abutment members, which is normally fixed, is withdrawn to enable the strut to be forced behind it, the member then being released to retain the rocker end in the idle position.  In another example, a mechanism is interposed between the strut and spring such that the spring can be further stressed as the mechanism passes over a dead-centre position carrying the rocker end from the ready to the idle position or vice versa in each of which positions it is held by the stressed spring.  In a third example the strut and spring form parts of a sub-assembly that can be rotated from the ready to the idle position of the rocker and latched in each position.

Abstract: GRANULAR ACTIVATED CARBON MANUFACTURE FROM BROWN COAL TREATED WITH DILUTE INORGANIC ACID                 Abstract of the Disclosure Granular activated carbon is manufactured from briquette of about 1" x 2", formed from brown coal, from which iron material has been extracted and which has a moisture content of about 15% by weight, by crushing and screening the pre-treated coal briquettes to produce 8/30 mesh granules, treating the granules with a dilute aqueous solution of inorganic acid (H2SO4, H3PO4 or HCl) at a concentration of about 1 to about 10% by weight to reduce the volatile content and thereby increase the fixed carbon content comprising: mixing the granules with the acid, washing off the acid, and drying the granules at least partially to a moisture content below about 25% by weight.  In one case the washed granules are dried pertially to a moisture content of about 10 to about 25% by weight without the addition of a carbonaceous binder such as coal tar pitch.  In the other case the granules are dried thoroughly and mixed with about 5 to about 15% by weight of coal tar pitch.  The so treated granules are ground to form fine powder of more than about 65% by weight -325 mesh, more preferably 75 to 85% by weight -325 mesh, which is compressed into shapes such as pellets of 0.5" diameter and 0.5" long under a pressure of 40,000 to 80,000 psi, and then granulated to obtain 6/20 mesh granules.  These reformed granules are devolatilized, without charring, by directly heating to and at a temperature higher than the charring temperature in an oxygen-free atmosphere, and then activated by heating to and at a temperature higher than the devola-tilizing temperature in an atmosphere containing a gaseous activating agent.  The overall yield of granular activated carbon is not less than about 22% by weight, dry basis, and the activated granules have a surface area of not less than about 900 m2/gram, an Iodine number of not less than about 900, an ash content of not more than about 7% by weight, an abrasion number of not less than about 70, an apparent density of not less than about 0.46 gram/cc, and a Molasses number of not less than about 200; which properties make them suitable for use in water and waste water treatment and in other applications.
