Abstract: PROCESS FOR THE MANUFACTURE OF COARSELY CRYSTALLINE TO MONOCRYSTALLINE SHEETS OF SEMICONDUCTOR MATERIAL ABSTRACT OF THE DISCLOSURE The invention provides a process for the manufacture of coarsely crystalline to monocrystalline sheets and/or plates of semiconductor material of preferred orientation. A meniscus of molten semiconductor material comes in contact with a moving, cooler substrate of the same coarsely crystalline to monocrystalline semiconductor material, during which, while transferring the preferred orientation, a thin sheet of the semiconductor material is pulled onto the substrate and, after cooling, becomes detached from the support. The substrate can be reused as often as desired.

Abstract: Case 3-13484/ARL 315/+        CANADA     PHOTOPOLYMERISATION PROCESS ABSTRACT      A layer of a liquid composition containing a compound (A) having in the same molecule at least one (meth)acryloyl group and at least one bicyclo [2.2.1]hept-2-ene-6-yl unit is exposed to actinic radiation so that the layer solidifies due to photopolymerisation of (A) through the (meth)acryloyl group(s), remaining, however, photocrosslinkable.  When desired, the solidified layer is exposed, as through a negative, to a substantially greater amount of actinic radiation, the parts so further exposed becoming more highly photocrosslinked through the bicyclo [2.2.1]hept-2-ene-6-yl unit(s) and hence insoluble.  An image is produced which can be developed by means of suitable solvents.  Examples of (A) include 3-(methacryloyloxy)-2-hydroxypropyl bicyclo [2.2.1]hept-2-ene-6-carboxylate and 2-(acryloyloxy)ethyl methyl-5-carboxybicyclo [2.2.1]-hept-2-ene-6-carboxylate.

Abstract: X-RAY MASK SUBSTRATE AND METHOD OF FABRICATION THEREOF An improved X-ray lithography mask has been fabricated by forming an X ray absorbing lithography pattern on a supporting foil of hydrogenated amorphous carbon. The substrate foil is formed by depositing a carbon film in the presence of hydrogen onto a surface having a temperature below 375.degree.C. The hydrogen concentration is maintained sufficiently high that the resulting film has at least one atom percent of hydrogen. A film having about 20 atom percent of hydrogen is preferred. While impurities are permitted, impurities must be maintained at a level such that the optical bandgap of the resulting film is at least one electron volt. A film with an optical bandgap of about 2 electron volts is preferred.

Abstract: AGRICULTURAL IMPLEMENT WITH HITCH CONTROL      ABSTRACT   A tractor-drawn agricultural implement of the type that requires a floating hitch member while operating but a rigid hitch member while in transport.  This is achieved according to the present invention by linkage connected between a hitch member control mechanism and the cranked axle that serves as the wheeled carrying structure for the implement main frame.  The linkage is arranged so that when the main frame is in its lowered or operating mode, a stop is clear from the hitch member control so that the hitch member has a free pivotal movement about a transverse axis, but when the frame is raised to transport or raised mode, the stop engages the hitch member control and renders the drawbar rigid.

Abstract: ABSTRACT OF THE DISCLOSURE          A workpiece carrier has a support bar centrally supported at one end of a stem portion.  The stem is carried at its opposite end on a base.  Columns are interposed between the ends of the support bar and the base.  Heat is applied to the columns, preferably by resistive heating elements, to heat them and cause their thermal expansion, causing the support bar ends to be bent away from the base.  A relatively flexible workpiece which has been bonded to the support arms on a surface facing away from the base will undergo the same bend.  This carrier has use in machining operations where the tool has a flat grinding or lapping surface against which the workpiece is held, and one wishes to increase the amount of material removed from the workpice towards one or both of its ends, relative to the remainder of the workpiece.

Abstract: ABSTRACT OF THE DISCLOSURE A plurality of proximity sensors are disposed in a  turbine  flow guide  to measure  flow guide-to-turbine blade tip distance  at various  points  around  the  flow guide.  The sensor signals are detected and the peak-to-peak voltage of the detected signals provides an indica-tion of the desired distance measurement.  The signals are also monitored and if ambient operating conditions causes the signals to exceed predetermined positive or negative thresholds,  corrective  signals  are  generated so  as  to bring the detected signal back into an acceptable range.         A proximity sensor is also provided to measure axial movement of the rotor to which the blades are at-tached so that the other sensor signals can be modified as a function of the measured axial position.

Abstract: A B S T R A C T          Ti and V impurities are removed from molten aluminium by adding a boron-bearing substance and agitating the aluminium in the presence of a dispersed chloride and/or fluoride flux active for fluxing (Ti,V)B2 particles.   It is preferred to perform the process by stirring the molten aluminium to generate a vortex, into which aluminium fluoride is introduced as a fluxing agent and for reaction with any alkali metal impurity present in the molten metal.  The alkali metal fluoaluminate thus generated assists the fluxing of the (Ti,V)B2, as does any cell electrolyte present in the molten aluminium.

Abstract: ABSTRACT OF THE DISCLOSURE      A computer system which  facilitates the execution of nested subroutines  and interrupts is  disclosed.  As each branch  transfer  within  the  program  is  executed  by a control area logic, a  microcommand initiates the transfer of  the return  address, which  has been  derived from the address in the  present routine, to a first  register of a push  down  stack.   In  addition,  the  microcommand also pushes down one level the contents of all of the registers in   the   stack  containing   previously   stored  return addresses.   Thus,  a   sequential  return  to  unfinished routines or subroutines is  provided.  When the subroutine or hardware interrupt service routine is completed, a code in  the address  field enables  the return address of the previously  branched  from  or interrupted  routine  to be retrieved from  the first register in  the push down stack and to provide  it as the address of  the next instruction to be executed.  The retrieval  of the return address from the  push  down stack  also pops  all other  stored return addresses  one  level  in   the  stack.   In  addition  to providing  multiple  levels  of  subroutine  and interrupt nesting, any number of  subroutines or hardware interrupts may  be  partially  completed  since  the  last  operating subroutine or hardware interrupt service routine is always the first one to be  completed.  Logic is also provided to detect  the occurrence  of a  hardware interrupt  during a return   sequence    such   that   the    requirement   to simultaneously push and pop the stack is properly handled.
