Abstract: ABSTRACT OF THE DISCLOSURE            When depositing layers of lumber (19) onto a support surface to form a stack (17) of lumber, spacing sticks (2) are placed between the  various layers at right angles to their longitudinal direction. One or more laying means (20), which carry the layers of lumber, move either continuously or intermittently towards, over and away from said stack support surface (21) on which the layers of lumber are placed  The spacing sticks (2,2') are inserted between separate layers of lumber by means of a movable means (13) which, while engaging one end of respective sticks, feeds said sticks substantially parallel with the direction of return movement of the laying means (20). The problem of laying the layers of lumber and the spacing sticks in a manner such that they interfere with one  another to the least possible extent is hereby solved in a simple and reliable manner. Pre-ferably the engaging means feeds the spacing sticks separately from an overlaying magazine (1) and maintains engagement with respective spacing sticks until said means has reached a remote turn position, at which the spacing stick is deposited onto the stack support surface or onto a partly formed stack, or to a preferably pivotable spacing-stick guide means (18) ar-ranged on the opposite side of the stack support surface. The invention also relates to a spacing stick laying means arranged adjacent a stack support surface (21) for receiving layers of lumber (19) . The said spacing stick laying means is arranged to operate in the aforedescribed manner. To this end, the spacing stick laying means comprises means in the form of a clamping arm (13) having a spring-loaded jaw means (14) which,while en-gaging one end of a spacing stick (2) supports said  stick in a free-bearing manner during said feed movement.

Abstract: METHOD OF CONTROLLING CALL TRAFFIC IN A COMMUNICATION SWITCHING SYSTEM           Abstract of the Disclosure Call traffic in a stored program controlled telephone switching system is effected by performing code gapping on telephone calls to a particular  called customer.  Code gapping is performed by limiting  the rate at which successive attempts may be made to complete all or part of a call to the particular called customer which is identified by a called  customer code, such as a Plain Old Telephone Service (POTS) called customer directory code.  A Minimum Time (MT), such as 10 seconds, is prescribed as the MT for the POTS number.  A record is made of the Last Clock Time (LCT) at which the last earlier allowed attempt was made to complete a call to the POTS number.  The Present Clock Time (PCT) is noted as the time at which completion of a subsequent call to the POTS number is presently desired.  The subsequent call completion attempt is denied if the MT for the POTS number has not expired since the LCT for the POTS number; but, if the MT has expired, the subsequent call completion attempt is allowed and the PCT becomes the new LCT for the POTS number.

Abstract: COAL GASIFICATION PROCESS    (D#76,476 -F) ABSTRACT Coal or other high ash containing carbonaceous solid fuel is reacted with a free-oxygen containing gas, with or without a temperature moderator, in a down-flow partial oxidation gas generator to produce a stream of raw synthesis gas, fuel gas, or reducing gas. A large portion of the combustion residue, i.e., molten slag and/or particulate solids that is entrained in the down-flowing generated gas stream is removed by gravity when the gas stream is passed through a diversion chamber where the velocity of the gas stream is reduced and its direction is diverted. The separated solid material and molten slag pass down through an outlet in the bottom of the diversion chamber and into a pool of quench water below.  Preferably, a small portion of the hot gas stream is passed through the bottom outlet of the diversion chamber to prevent plugging.  The main gas stream leaving the diversion chamber through the side outlet passes upward through a solids separation zone, optionally including gas-gas quench cooling, cyclones, filters, im-pingement separators, or combinations thereof, where ad-ditional entrained solids are removed and where some cooling of the gas stream may be effected by impingement with a cooled cleaned recycle portion of the gas stream. Next, most of the sensible heat in the gas stream is recovered by the production of steam.  The gas stream, with a substantially reduced solids content,  is passed through the tubes of one or more shell-and-straight fire tube gas coolers. Each gas cooler has one or more passes on the shell and tube sides and is preferably in an upright position with fixed tube sheets.

Abstract: A process for fusion joining the ends of optical fibers includes aligning the ends of the two fiber cores to be joined facing each other such that at least one of the ends is free to be displaced laterally and there is no axial force between the two ends. The ends of the fibers are heated by producing a heat field with a predetermined distribution, for a predetermined period until attenuation of light transmitted through the fused joint increases, so as to cause partial fusion of the cores while maintaining sheathing of the fibers intact. A device for fusion splicing the two ends includes two opposed fiber supports for maintaining the end portions of the optical fibers to be fusion spliced in an approximately aligned position, the supports being slidable along the axes of the fibers being mounted on said supports such that their ends are free to move laterally. Optical means, such as a binocular microscope, is provided for checking whether the ends of the fibers are in the position where they engage one another without exerting any axial force on each other. A propane-oxygen flame heating device establishes a controlled distribution of heat field for heating the core ends.

Abstract: Planetary Steering Differential Abstract Continuously driven vehicle steering differentials have heretofore been too complex and have undesirably incorporated a second cross shaft for counter-rotating a pair of oppositely located planetary elements.  The instant planetary steering differential overcomes these deficiencies by including first, second and third interconnected planetary mechanisms individually having first, second and third planetary elements for rotating a pair of output members in the same direction and at the same speed in response to rotation solely of a first input member and holding a second input member stationary, and for rotating the output members at different speeds in response to rotation of the first and second input members.  The first input member is driven by a transmission and is connected to one of the planetary elements of the second and third planetary mechanisms, the second input member is driven by a reversible steering motor and is connected to another of the planetary elements of the second and third planetary mechanism, and one of the planetary element of the first planetary mechanism is held stationery as a reaction.

Abstract: A SEMICONDUCTOR LASER BONDING TECHNIQUE Abstract of the Disclosure In a method and apparatus for bonding a semiconductor laser chip to a heatsink and testing the bond obtained, temperature in the bonding operation is regulated by passing a small fixed current through the forward biased laser and monitoring corresponding change in voltage caused by alteration of the laser pn junction temperature. Current is passed to the laser through a floating contact consisting of a conducting vacuum pick-up pressed against the laser top surface. Bond integrity is subsequently tested at low temperature by passing a dc current greater than a threshold current through the laser and measuring the resulting light output and then passing a pulsed current with identical peak current level and again measuring light output. The difference in light output is a function of the bond thermal resistance.

The  pressurized reactor coolant is utilized to raise the drive rod into contact with and to pivot the latching mechanism so as to allow the drive rod to pass the latching mechanism.  The pressure in the housing is then equalized which allows the drive rod to move downwardly into contact with the latch ing mechanism but remain in a raised position with respect to  the  reactor  core.  Once  again,  the  reactor coolant pressure may be utilized to raise the drive rod and thus pivot the latching mechanism so that the drive rod passes above the latching mechanism.  Again, the mechanism pres-sure can be equalized which allows the drive rod to fall and pass by the latching mechanism so that the drive rod approaches the reactor core.
