Abstract: Abstract of the Disclosure A drive mechanism for advancing workpieces through a plurality of spaced-apart work stations which are arranged so that the distances between certain adjacent work stations are greater than the distances between other adjacent work stations.  During an advancing stroke, the drive mechanism moves each workpiece from one work station the entire distance to the next work station so that no workpiece occupies any space between adjacent work stations after the completion of the advancing stroke.  The drive mechanism includes a rotary drive crank to which a plurality of drive links are pivotally mounted.  Each drive link is connected to a transfer bar which is guidably supported for straight line reciprocal movement to engage and advance the workpieces. predetermined half-cycle movement of the drive crank imparts contemporaneous movement to the transfer bars which are moved through different distances during the half-cycle movement of the drive crank to advance all workpieces to the next work stations.

Abstract: ABSTRACT OF THE DISCLOSURE     A multiple piece torch tip and a method of making a multiple piece torch tip.  The multiple piece torch tip comprises an inner piece disposed interchangeably within an outer piece.  The inner surface of the outer piece has a plurality of regularly spaced slots which decrease in size radially outward and which combine with the smooth exterior of the inner piece to form preheat orifices.  The method of making the multiple piece torch tip comprises a swaging step which in one step forms the outer piece.  In the swaging step a tubular blank is swaged about a ribbed mandrel.  The mandrel presents a monotonically decreasing radial cross-sectional area with respect to the blank for facilitating removal of the swaged outer piece without damage thereto.          Also provided is a step of forming an inner piece of a size such that the inner surface of the outer piece and the outer surface of the inner piece combine to form preheat orifice configurations.

Abstract: LOCKING CONNECTION FOR SUPPORTING GRID SYSTEMS             ABSTRACT OF THE DISCLOSURE     A first support member having a web with a slot and a pair of second support members having locking connectors insertable through the slot in side by side relation, each connector having a resiliently yieldable finger engageable against the web after insertion through the slot for interlocking the first and second members.          Each connector has a laterally projecting detent on the side opposite the finger, an opening providing an arcuate generally vertical shoulder spaced rearwardly from the detent, and a laterally projecting spring retainer on the same side as the detent extending forwardly at least partially across the opening.  When the connectors are inserted through the slot in side by side relation the forward end of each connector is confined against the other connector by the retainer thereof with its detent engaging the arcuate shoulder of the other connector, thereby interlocking  the second support members, the retainers yielding resiliently to permit passage of the detents into the respective openings.  The arcuate shoulders accommodate generally vertical relative angular movement of the second support members, the retainers maintaining the interlock during relative angular movement both vertically and horizontally. In one form, the openings and spring retainers are elongated to axial expansion of the members under elevated temperatures.

Abstract: ABSTRACT OF THE DISCLOSURE         An improvement is provided in a system comprising (i) a source of fresh hot water, (ii) a source of waste hot water fed from the fresh hot water, and (iii) a drain for discharging the waste hot water.  The improve-ment comprises a hot water heat recovery system interposed between the source of waste hot water and the drain, comprising: (a) a water/water heat exchanger; (b) conduit means automatically controllably continuously and selectively passing the waste hot water to the heat exchanger before the waste hot water passes to the drain; (c) conduit means automatically con-trollably continuously selectively passing the cool fresh water to the heat exchanger to be preheated and pipe means connecting to said heat exchanger to said shource of fresh hot water and for continuously withdrawing the preheated water from the heat exchanger, and contuit means automatically controllably, continuously and selectively simultaneously passing the waste hot water to the heat exchanger in heat exchange contact only with the cool fresh water; and (d) temperature control means associated with the conduit means to shunt the waste hot water from the heat exchanger to the drain and simultaneously to shunt the flow of cool fresh water from the heat exchan-ger when the water temperature drops below a selected value.  By these means, the waste heat in hot water is recovered and is used to preheat in-coming cool water before it proceeds to the hot water heater and the waste hot water does not enter the heat exchanger unless it is hot enough.  Thus plugging of the heat exchanger by sedimentation and precipitation of solids out of cooler water is minimized.

Abstract: METHOD FOR CONTROLLING THE OXYGEN            LEVEL OF SILICON RODS PULLED ACCORDING               TO THE CZOCHRALSKI TECHNIQUE            Abstract The present invention relates to an improved method for pulling semiconductor monocrystalline rods, in parti-cular silicon rods, according to the Czochralski tech-nique.  The average oxygen concentration profile (02) is first determined for a given pulling equipment as a function of the length (L) of the rods pulled at a con-stant crucible rotation speed, that is, (02) = f(L).          The improvement consists in pulling the rods at a crucible rotation speed VRC which varies as a function of L accord-ing to a predetermined profile to ensure an oxygen concen-tration profile which is about constant along the rod.          In practice, under normal. conditions, it is sufficient to ensure at any moment that: grad VRC  =  k grad f(L) where k is a positive proportionality factor depending on the operating conditions.  For example, if the oxygen concentration profile (02) at a constant rotation speed (Ro) represents a curve in bell form, the desired pro-file of the crucible rotation speed VRC will have in-verse form of the bell curve.  The oxygen concentration profile of the rod thus obtained will be virtually linear.          This method is mainly used to manufacture semiconductor wafers whose oxygen level will match the specification of the different production lines.

Abstract: Abstract of the Disclosure A combination coupling and sheave in a variable speed belt drive in which a variable pitch sheave has a fixed flange, an axially shiftable flange and a shaft con-nected to the drive motor by a flexible coupling with the hubs thereof secured to the motor and sheave shaft.  The inventive concept includes mounting the coupling hub on the sheave shaft in a bearing of a pillow block at the end of the shaft and connecting the fixed flange of the sheave to the hub, so that the fixed flange is driven directly by the hub rather than solely by the shaft, and the slidable flange is driven through the shaft, thus creating split power paths between the flexible coupling and the fixed flange and between the coupling and the slidable flange through the sheave shaft, thereby reducing the load on the operating parts of the sheave.
