Abstract: ABSTRACT OF THE DISCLOSURE      The width of a piece of timber, such as a board is measured with a device including a laser tube emitting a laser beam to be reflected by a rotatable mirror polyhedron and a para-bolic reflector into a direction along the board, mirror rasters being provided at intervals along the board so as to reflect laser beam pulses onto the board, each raster including a group of mirrors reflecting the beam pulses onto spots of the board that are spaced apart laterally across the board, and detecting means being provided for receiving the pulses reflected from the board surface in order to obtain information about the board width.  Preferably, the pulses received by the detectors are transferred to a computer which calculates, in a manner known per se, the optimal sawing width for the board.  Instead of the reflector, lens means may be used for directing the beam along the board.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention applies pressurized air and vacuum to container interiors as they are being conveyed through the cleaning station in the course of their forward travel.  Cleaning according to the invention occur  through the combined action of a plurality of air jets which dislodge any foreign matter from the container interior and a vacuum drawn through an arcuate slot evacuate  and draws out the dislodged contaminents.  The aforementioned operation taking place as containers continuously advance in a circular conveyor in the opening down position.          After this operation, the containers are urged to assume a horizontal position and are subsequently oriented into the opening up position for travel to a new work station.

Abstract: VEHICLE WHEEL SUSPENSION SYSTEM                   ABSTRACT OF THE DISCLOSURE         A pair of unsprung axle structures are pivotally connected to the rigid frame of a vehicle on a pair of laterally spaced longitudinally extending axes.  These laterally spaced axes are at the approximate height of the vehicle wheels mounted on the axle structures and are spaced laterally inward from the wheels.  At a lower height a transverse link is pivotally connected at its opposite ends to lower portions of the axle structures to form a tie bar therebetween.  This suspension arrangement establishes an effective pivot or roll center for the end of the vehicle supported by the axle structures, which is at a higher elevation than the center of gravity of the vehicle.  During operation, the wheels may traverse uneven ground while pro-viding vehicle support; that is, one axle structure may swing upwardly as the other axle structure swings downwardly.  By permitting the wheels to traverse uneven ground and yet provide support for the frame, the suspension system permits the full tread of the wheels to be utilized as a support base for the vehicle thereby providing excellent vehicle stability.

Abstract: PROTECTIVE RELAYING APPARATUS      OF THE UNBLOCK TYPE              ABSTRACT OF THE DISCLOSURE         Protective relaying apparatus for power trans-mission lines of the unblocking type which utilizes a fault signal from a remote portion of the protected line to initiate a normal transient blocking timer which in the absence of a local fault signal (within its timing period) will initiate a desensitizing operation and pre-vent the tripping of the local breaker due to the presence of transient and an additional timer arranged to be ener-gized in response to a local fault signal and effective when timed out to initiate the normal transient blocking timer in the absence of the remote fault signal.  In a modified form of the apparatus, the concurrent reception of the received and local signals (indicative of a fault in the line section protected thereby) deactivates the normal timer and prevents its further timing operation to increase the margin of coordination when transient blocking should not occur.

Abstract: HYDRAULIC PUMPING UNIT WITH A VARIABLE SPEED TRIPLEX PUMP     ABSTRACT OF THE DISCLOSURE         This  invention  is a  hydraulic  pumping  unit which  uses  a cyclone feed  pump means  to vary  the speed  of the  above-ground pump, while still providing proper  cleaning of the power fluid  for the down-hole pump.  The ability  to conveniently change the speed of the above-ground pump  allows the speed  of the pump  to be reduced  whenever well conditions make such  a reduction appropriate, and this  provides a very substantial reduction in  the cost of power  for the prime  mover (typi-cally an electric  motor).  In addition to  the cyclone feed pump  and a speed control means  to vary the speed  at which the prime  mover drives the above-ground  pump, this  invention uses  a flowback  line connected from the cyclone overflow to the feed pump inlet.

Abstract: Abstract of the Disclosure An electrical resistance welding apparatus for making an integral and homogeneous connection between a terminal and a battery lug accomplished by limiting the area of contact between the two as by equipping the battery with an insulation card which is at least partially disposed between the lug and the terminal.  The apparatus presses a portion of the overlapping area of the lug through an opening in the insulation card to make contact over a relatively small area with the terminal by first moving one electrode to contact the terminal and then moving the remaining electrode to contact the lug.  The electrode assemblies clamp the lug and terminal together.  Current is provided to the electrodes to heat up the area of contact as it is made, thereby melting the lead in the opening in the insulation card.  As the lug and terminal are continuously squeezed together, more cold lead flows into the opening where the fusion is taking place.  When molten lead substantially fills the opening, the current to the electrode ceases and the electrodes are withdrawn leaving an integral and homogeneous connection formed between a portion of the terminal surface and a portion of the overlapping lug surface.  A method for resistance welding the terminal of the battery is also described.

Abstract: COMPUTER SYSTEM ARCHITECTURE FOR PERFORMING NESTED LOOP OPERATIONS TO  EFFECT A DISCRETE FOURIER TRANSFORM                       Abstract of the Disclosure A computer system architecture and method for performing the Discrete Fourier Transform on a set of N sampled input signals wherein N is chosen to be the product of a group of predetermined relatively prime factors (n1?n2?...?nL).  The present architecture then proceeds to the solution of the Fourier transform via a unique nested loop solution method, wherein each loop is specifically related to each factor and wherein no multiplications are performed in the outer loops said method being further characterized by the fact that the system control is automatically passed to the next inner loop whenever a multiplication instruction is encountered.  A unique predetermined sequence of operations which is unique to each factor (n?) is built into the system controls and automatic control means proceed from one sequence to another depending upon the factors (n) associated with a chosen  N.  The unique set of instruction sequences for each small factor of (n) is predicated upon a unique solution for the small Fourier transform matrix associated with said factor.   Means are included in the system so that in all outer loops all addition operations required are performed on vector quantities and, in the single innermost loop, additions and multiplications are performed on scalar quantities.  Means are additionally provided for determining composite coefficients to be used in multiplications occuring in the innermost loop, said composite coefficients comprising the product of the multiplication coefficient to be currently performed in the innermost loop as well as the coefficient essential with each pseudo multiply in each outermost loop currently involved in the current innermost loop computation.     After all loop input adds, multiplications, and output adds have been performed the resultant output vector is the Fourier transform of the original input vector.         In addition to the actual transform procedure an input vector reordering operation must be performed and an output vector reordering operation.
