Abstract: ABSTRACT OF THE DISCLOSURE      A veneer lathe for turning a log thereon to cut off veneer sheets therefrom.  The log is principally driven by a rotary roller having a plurality of projec-tions therearound, which roller is pressed against the log to ensure positive engagement with the periphery thereof.  The log is formed with a center bore at a core portion thereof.  A spindle to support the log is inserted into the center bore to prevent the log deflection due to the pressure from the rotary roller.  Another form of this veneer lathe is additionally provided with a center bore forming mechanism together with a centering mechanism for the boring operation such that a center bore is formed in the log in advance before being turned on the veneer lathe.

Abstract: ABSTRACT OF THE DISCLOSURE.          Improved slit radiography.     In radiography apparatus a moving slit colli-mator is disposed between an X-ray source and a patient undergoing examination. Radiation is detected with an X-ray image intensifier and television pickup chain. The field of view of the television pickup is limited to that area of the output screen of the X-ray image intensifier which corresponds to the image produced by direct radiation which passes through the moving slit.          The view of the television pickup may be limited by a second slit, disposed between the X-ray image intensifier and television pickup which moves in synchronism with the first slit. Alternately, the view of a television pickup may be limited by synchronizing scan signals for the pickup of the with the motion of the slit collimator.

Abstract: Abstract of the Disclosure A process or method of and apparatus for the in-ladle treatment of molten base metal iron with a nodularizing agent (e.g., a magnesium bearing alloy) so as to produce substantially uniform spheriodal graphite in the iron.  The process involves placing a desired quantity of the nodularizing agent in a reaction chamber in a treatment ladle, the latter having a main chamber, a charging and filling passage leading to the reaction chamber, and one or more passages leading from the reaction chamber to the main chamber of the ladle.  Molten base metal iron is then poured into the reaction chamber via the charging and filling passage thereby to effect a reaction between the nodularizing agent and the molten base metal.  A hydrostatic pressure head of the molten base metal is rapidly established over the reaction chamber of sufficient depth thereby to minimize the vaporization of the nodularizing agent and to maximize the recovery of the nodularizing agent in the base metal.  The base metal with the nodularizing agent dissolved and mixed therein is then permitted to flow into the main chamber via the passages.  The base metal with the nodularizing agent therein is held in the main chamber for a time sufficient to convert the base metal into a matrix which when solidified is populated with spheroidal graphite.        The apparatus of this invention relates to a ladle in which the above-identified process can be carried out.

Abstract: ABSTRACT            A connector member for joining a channel-section member e.g. a channel-section cross-rail in a suspended ceiling structure to a member extending transversely e.g. a channel section main grid member. The connector member tapers in plan from its front end which is provided with a connector portion for engaging with the transversely-extending member. At the front of each side the connector member has a notch which engages the side walls of the channel member when the tapering side portions are inserted through horizontally extending slots in the channel side walls. Adjacent the rear edge, each side of the connector body has a rearwardly-facing shoulder which engages the rear edge of the slot in the channel side and resists disengagement of the notches from the channel side walls by rearward displacement of the connector body relative to the channel member.

Abstract: HEAT FLOW DETECTOR FOR RECESSED INCANDESCENT FIXTURES               ABSTRACT OF THE DISCLOSURE    A heat flow detector is described which measures a predetermined rate of heat flow in its surroundings.          The surroundings being in the proximity of a recessed incandescent fixture which is designed to operate safely in the designated environment.  Should the operating environment change for the fixture it will be sensed by the heat flow detector. If the operating environment becomes more dangerous so that a fire or other damage may occur the heat flow sensor will turn the incandescent lamp off and on at a flow rate to indicate the changed operating environment.    The heat flow detector will cause a slow turn off and on if an oversize lamp is inserted in the incandescent fixture.  The heat flow detector will then prevent an overheated condition due to an incorrect bulb.

Abstract: HARVESTING HEADER WITH ADJUSTABLE DRAPER     FOR LEFT, RIGHT OR CENTER DELIVERY              Abstract Of The Disclosure The header has generally transversely dis-posed, flat, apron-like conveyor mechanism for receiv-ing the stalks of grain or other crop materials severed along the leading edge of the header and for gathering such materials so that they might be discharged in a continuous stream for producing a windrow.  The con-veyor mechanism comprises a pair of largely self-contained sections which may be latched together and shifted to one end of the header with their upper surfaces driven in a common leftward direction for left delivery and discharge, or shifted to the oppo-site end of the header and driven with their upper surfaces in a righthand direction for right end deliv-ery of the materials, or they may be unlatched and separated while their upper surfaces are driven in opposite directions centrally toward one another for centered delivery of the materials.  By virtue of a latch for releasably connecting the sections together and a cooperating, selectively operable latch releas-ing device, the necessary shifting adjustment of the sections between their various positions may be accomplished through the medium of only a single shifting assembly coupled with one of the sections. A special selectively engageable and disengageable drive line arrangement for the conveying surfaces of the conveyor sections includes components which are matingly engaged or disengaged and driven in one or the other of two opposite directions depending upon the shifted position of the sections by the shifter assembly.

Abstract: An apparatus for blood analysis to determine the rate of corpuscle sedimentation. The apparatus has a first support (1) with several graduated tubes (4) open at both ends and held vertically in spaced relation on the first support. The tubes (4) have enlarged lower ends (4b) which can diverge. A second support (2) has blood sample containers (13) of larger diameter than the vertical tubes on the first support. The containers (13) are spaced apart on the said second support, the same distance as the tubes on the first support so the containers are respectively, vertically below the tubes. Sealing and flow inducing members engage in the diverging lower ends (4b) of the respective tubes. The support means (1, 2) are movable with respect to each other between a first position in which the tubes are vertically above the containers, and a second position in which the lower ends of the tubes are immersed in the containers. The sealing and flow inducing members are mounted on the first support for simultaneous movement between a lower position away from the tubes and an upper position engaging within the enlarged ends of the tubes. The movement of the sealing members into engagement with the interior of the tubes causes a predetermined quantity of blood to be forced upwardly into the smaller diameter graduated portions of each tube to permit determining the sedimentation rates of the different samples.
