Abstract: 43-293/U3.6 COMPATIBLE INTERNAL BONE FIXATION PLATE     Abstract of the Disclosure An internal fixation plate for bridging two portions of a broken bone is formed to have properties, in terms of bending,  axial,  and  torsional  stiffness suitable  for  the bone being mended.  These properties include high resistance to bending and torsional stresses, and relatively low axial stiffness.    One  plate  configuration  which  has  been determined to have the desired stiffness properties is an elongated flat hollow metal plate or tube.  Arrangements are provided  for  precluding  bone  ingrowth,  and  this may  be achieved  by  filling  the  member  with  a  medically  inert substance, such as silicone rubber or ultra high molecular weight polyethylene,  or by sealing the openings  into the tubular plate.  The materials of the bone fixation plate may be selected  for  their mechanical properties,  and also as biologically inert substances which will not have adverse physiological effects when embedded in the human body.

Abstract: DEVICE FOR MOUNTING ELECTRICAL DEVICES ON A PLATE     ABSTRACT OF THE DISCLOSURE     In devices for mounting electrical devices, in particular switch, command or signal devices on a plate, like a bottom plate of a switch box or an assembly plate of a switch box or switch board of the type with at least one mounting bar for the devices disposed parallel to the plate as well as with two vertically-extending supports mounted on the plate for each mounting bar and with screw connections between the supports and the mounting bar, the difficulty exists that it is hard to reach the screw connections between the supports and the mounting bars, because of tight space conditions due to a tight arrangement of the devices relative to each other and due to the wiring which leads to the devices.  In order to be able to obtain a simple servicing and safe support of the mounting bars on the supports, even at the tightest space conditions, it is proposed to provide screws which are disposed vertically with respect to the plate and which cooperate with clamping plates which are so designed that by tightening the screws, the supports are rigidly connected with the mounting bar due to the clamping effect.

Abstract: ADDRESS RANGE TIMER/COUNTER            Abstract of the Disclosure A system for measuring program execution time compares all addresses occurring on a memory bus to an upper limit number and a lower limit number to produce a signal which indicates if each address occurring on the memory bus is within a range represented by the upper limit number and the lower limit number.  The signal is utilized to either enable incrementing of a counter at a predetermined rate or to increment the counter once for every new address occurring on the memory bus within the range.  The contents of the counter represent either the accumulated time of execution of instructions having addresses within the range or the number of instructions executed having addresses within the range.          The system includes a display for displaying the contents of the counter.

Abstract: A B S T R A C T            The invention relates to a method for recovering useable products from waste products deriving from the manufacture of aluminium fluoride on the basis of aluminium hydroxide and fluosilicic acid. Silica contaminated with fluorine and aluminium and obtained in the manufacture of aluminium fluoride is dissolved with a strongly basic hydroxide, whereafter the first solution obtained is mixed with a second solution, obtained by dissolving aluminium hydroxide with a strongly basic hydroxide, and with waste mother liquor and optionally also washing water from the manufacture of aluminium fluoride, in such proportions that the pH-value of the mixture is from about 10-14. The silicate content of the waste products supplied is precip-itated as a silicoaluminate, which is separated off, preferably by filtration, for optional further treatment or for direct use, where-after fluorine, when present in the waste products, is recovered from filtrate by further precipitation, and whereafter the filtrate is passed to a recipient or utilized, for example, as process water in other processes. The fluorine content can be recovered from the filtrate by adding thereto an aluminium compound in an amount suffi-cient to precipitate out substantially all the fluorine contained in the filtrate as a fluoroaluminate respectively, which is then sepa-rated off.

Abstract: Abstract of the Disclosure:            Set out herein is a gearing mechanism wherein one gear of a smaller diameter engages in partial mesh another gear either in the form of a rack or a gear of a larger diameter.  The pitch of the smaller diameter gear is made different than the pitch of the rack or the larger diameter gear thus achieving a pitch differential.  To accommodate this in-equality in pitch the teeth of the smaller gears are radiused and the larger gear or rack may include rollers which engage these rounded teeth to accommodate the dif-ference in pitch by relative movement.  In alternative implementations the smaller gear, rather than including teeth, may include a plurality of permanent magnets, once more distributed at a pitch different than a plurality of permanent magnets embedded in the larger gear or rack.  The coercive force between the magnets can thus be used to transmit power at a gear ratio equal to the pitch differ-ential.
