Abstract: CARRIAGE ASSEMBLY WITH SHIFTABLE FORKS                         Abstract It is desirable to have relatively clear forward and downward vision for the operator of a lift truck which has a side shiftable carriage.  Herein, a structure mounts a top end portion of a vertical leg of a tine to transfer substantially only horizontal forces to an upper bar of a side shifter.  A structure having a first and second bearing structure serves for mounting a bottom end portion of the vertical leg to transfer vertical forces to a lower bar of the side shifter.  Since vertical forces are taken up by the lower bar, the upper portion of the carriage assembly can be relatively light and small, thus allowing clear forward and downward vision for the vehicle operator. This also results in a total carriage structure which is lighter in weight.

Abstract: CRUCIBLELESS PREPARATION OF RAPIDLY SOLIDIFIED FINE PARTICULATES                         ABSTRACT      A mass of normally solid material, e.g. metal or metal alloy, which at a temperature within 25 percent of its equilibrium melting point °K has a surface tension of 10 to 2500 dynes/cm. and a viscosity of 0.001 to 1 poise, is changed into fine solid particulates, preferably flake-like to almost spherical shape.  A solid mass of the material has a portion thereof, e.g. tip or edge, unconfined by a crucible or the like, heated, such as by a flame or electron beam to alter that portion to a molten state whereby molten droplets or globules fall therefrom to contact a rapidly moving wall of a centri-fugally disposed rotating liquid quench fluid, e.g. water or oil, and upon contacting are disrupted and broken up into finer globules or particles which are swept away with and quenched in the rapidly moving quench fluid to become rapidly solidified as fine particulates.  These fine particulates subsequently are separated from the quench fluid and classified to find utility for example in powder metallurgical applications.

Abstract: ABSTRACT OF THE DISCLOSURE           An attachment device in the form of a bearing hous-ing and an arm extending out through an opening in the hous-ing.  The arm is supported in a bearing support in the hous-ing and serves to carry, at the end opposite the housing, an ear muff to move with a rocking motion between a station-ary rest position and a position wherein the ear muff exerts a pressure around the wearer's ear.  A separate spring com-ponent, preferably annular in form, is rotatably supported in and prestressed to bear against, on one side, an adjus-table spring support, which is located inside the housing and remains stationary during the rocking motion, and, on the opposite side, the end of the arm located inside the housing.  By this arrangement there is exerted on the said end of the arm a controlled force directed away from the spring support for stabilizing the arm in its two positions. The spring support may consist of a rocker, the position of that part of the rocker in which the spring component is supported being adjustable against an adjusting means with respect to the nearer end of the arm to permit alteration of the prestressing of the spring component.  The adjusting means consists of a cover with an annular collar of thick-ness varying along the extent thereof.  The collar rests against the inside of the ring flange of a base, which is rotatable with respect to the said adjusting cover.

Abstract: LATHE CHARGER HAVING DIRECTIONALLY LIMITED ADJUSTMENT OF SCANNING SPINDLES                           Abstract A veneer lathe charger apparatus is disclosed for scanning a rotating log with light to determine its optimum yield axis and adjusting the charger spindles through a greater range necessary for large diameter logs to position such axis at a predetermined transfer position.  The log is rough centered with its longitudinal axis at a scanning position by rough centering arms which are released prior to scanning.  After scanning the log is moved from its scanning position to align such optimum yield axis with a predetermined transfer position axis where it is engaged by a transfer clamp means for movement to a lathe axis position without reclamping by such centering arms.          A spindle support and adjustment means is provided for adjusting the charger spindles to move the optimum yield axis of the log to the transfer position axis.  A control means enables directionally limited adjustment of the charger spindles a greater distance away from the transfer clamp means than toward such clamp means.  The control means causes the charger spindle means to rotate the log into a different rotational position after scanning in order to enable the spindle support and adjustment means to move the log towards the clamp means.  This directionally limited adjustment of the scanning spindles enables the transfer clamp means to clear the spindles when such transfer means moves from the lathe position to the transfer position prior to engagement of the log and to engage the ends of the log while the charger spindles are still engaged, thereby eliminating any need to reclamp the side of the log with the rough centering arms.

Abstract: PC(HO) 6348 BONE PROSTHESIS WITH CONTROLLED STIFFNESS                             Abstract A novel bone prosthesis for use in healing a bone fracture is disclosed comprising a strong, rigid non-absorbable structural member and a biologically absorbable element held in use under compression against the structural member.  Use of the novel prosthesis combines an excellent initial stabilization of the fixed fracture with a gradual shifting of stress-bearing from the prosthesis to the bone in the fracture region as the fracture heals.  Thus, problems associated with stress-shielding during healing are alleviated.  The structural member may be, e.q., a bone plate, intramedullary rod or hip nail.

Abstract: ABSTRACT OF THE DISCLOSURE     A circuit for supplying drop current to the subscriber connected to the remote terminal of a central office powered telecommunications system.  A switching regulator is included in the circuit for generating the drop current.  The switching regulator adjusts its conduction time as a function of the length of the loop connecting the subscriber to the terminal such that the subscriber consumes only that power required by the loop length.  The switching regulator operates in response to a reference current generated by a control circuit.  A cen-tral office supplied signal on the transmission means connecting the central office to the terminal is used for transferring power to the terminal.  The amplitude of that signal at the terminal varies with system load.  When that amplitude deviates in a predetermined direction from a reference signal of pre-determined amplitude the reference current and therefore the drop current to all off hook subscribers is uniformly decreased by an amount which allows the power transferring signal ampli-tude to be maintained substantially equal to the amplitude of the reference signal.

Abstract: Abstract of the Disclosure A multiprocessor system the kind in which two or more separate processor modules are interconnected for parallel processing includes two redundant interprocessor buses dedicated exclusively to interprocessor communication.  Any processor module may send information to any other processor module by either bus.  The buses are shared in use by the processor modules on a time-sharing basis.  Use of each bus is controlled by a special bus controller.  The multiprocessor system includes an input/output system having multi-port device controllers and input/output buses connecting each device controller for access by the input/output channels of at least two different processor modules.  Each device controller includes logic which insures that only one port is selected for access at a time.  The multi-processor system includes a distributed power supply system which insures uninterrupted operation of the remainder of the multi-processor system in the event of a failure of a power supply for a part of the system.  The distributed power supply system includes a separate power supply for each processor module and two separate power supplies for each device controller.  Either one of the two power supplies provides the entire power for the device controller in the event the other power supply fails.          The distributed power supply system permits any processor module or device controller to be powered down so that on-line mainten-ance can be performed in a power-off condition while the rest of the multiprocessor system is on-line and functional.  The multiprocessor system includes a memory system in which the memory of each processor module is divided into four logical address areas -- user data, system data, user code and system code.  The memory system includes a map which translates logical addresses to physical addresses and which coacts with the multiprocessor system to bring pages from secondary memory into primary main memory as required to implement a virtual memory system.  The map also provides a protection function.  It provides inherent protection among users in a multiprogramming environment, isolates programs from data and protects system programs from the actions of user programs.  The map also provides a reference history information for each logical page as an aid to efficient memory management by the operating system.          The multiprocessor system includes in the memory of each processor module an error detection and correction system which detects all single bit and double bit errors and which corrects all single bit errors in semiconductor memory storage.

Abstract: ABSTRACT OF THE DISCLOSURE           An electronically controlled, coin-operated latch mechanism includes an inclined coin chute through which different size coins travel at different angles to provide an electrical connection between different coin detecting contacts.  An elec-tronic circuit is responsive to signals generated at the contacts to totalize and store the monetary value of deposited coins.          When the stored value equals or exceeds a programmed price, an electromagnet is actuated to enable a hook to be pivoted away from engagement with a latching member.  Subsequent movement of the released latching member causes deposited coins to be placed in a coin receptacle and resets the hook for subsequent latching.

Abstract: AC Power Control Circuit Abstract An improved control circuit for accurately regu-lating the power from a supply of unregulated AC voltage to a load, such as a fan motor, via a signal responsive conduction-control switch.  The circuit employs first and second comparators.  One input to the first comparator is a DC signal representative of desired  power level.  The other input of the first comparator is a signal having a DC component and a ripple component.  The output of the first comparator is a rectangular waveform having a duty factor which is a function of the desired power level relative to the reference load power level.  The first comparator output is integrated and then sup-plied as an input to the second comparator.  A saw-tooth signal of constant DC level provides the other input to the second comparator.  The sawtooth is a submultiple, or preferably a multiple of the AC sup-ply frequency.  The output of the second comparator is another rectangular waveform, the duty factor of which is a function of the DC level of the inte-grated signal and is used to control the conduction timing of the conduction control switch.  Preferably, the combined DC-with ripple-signal input of the first comparator is provided by feedback from the second comparator output which is passed through a voltage scaling network connected to an unregulated DC sup-ply.  The time constants of the closed loop are se-lected to provide a temporary power overshoot when increasing the power level.  Supplemental limit circuits provide limit signals directly to the second comparator input.
