Abstract: Abstract of the Disclosure:     A process is provided for the purification of a proteinaceous physiologically active substance having antitumor activity, which is induced by administering to a rabbit at least one substance having a capacity for stimulating reticuloendothelial system and then injecting endotoxin from a Gram-negative bacterium into the rabbit.  The process comprises contacting a crude solution of said proteinaceous physiologically active substance with a basic anion exchanger to have said physiologically active substance adsorbed on the anion exchanger, eluting the adsorbed physiologically active substance, and subjecting the eluate containing said physiologically active substance to gel filtration with a gel suitable for separation of a substance with a molecular weight in the range of 30,000 to 70,000.  The purified preparation of said physiologically active substance thus obtained may be used as an antitumor agent for the treatment of malignant tumors.  Said physiologically active substance is isolated by subjecting the purified preparation successively to affinity chromatography on immobilized Cibacron Blue F3G-A, gel filtration, affinity chromato-graphy on immobilized concanavalin A, preparative electrophoresis on polyacrylamide gel and gel filtration.

Abstract: PATENT APPLICATION                For:  AN IMPROVED SYSTEM AND FILM GATE       FOR ACCURATELY IMAGING INFORMATION ON A FILM BY A CHARGED PARTICLE BEAM                    ABSTRACT OF THE DISCLOSURE     An improved particle beam recorder system having a pressure equalizing film gate including a platen for receiving a film thereon in pressure relieved relation to avoid trapping dis-tortion causing air between the film and the platen.  The platen can provide a curved film receiving surface and a predetermined tension can be applied to the recording film disposed on the platen to assure positive contact between the film and the platen  A motor driven film advance system is provided to intermittently advance the film through the film gate to thereby intermittently provide fresh and stationary film for exposure and image recording.  A particle beam generator is disposed in predetermined relation with the film and the film gate and the recording beam produced thereby is electronically positionally corrected for the known geometric distortions introduced by a predetermined continuous curvature of the film gate and the predetermined tensioning of the film to produce accurate imaging on the film.

Abstract: Abstract of the Disclosure A log splitting method and apparatus includes placing a charge of blasting powder in a log splitting blasting wedge, axially driving the wedge into one end of a log to be split, adjusting the height of a wedge receiving sleeve on the tower of an anchor structure and moving the anchor structure up against the wedge, igniting the charge in the wedge, thereby blasting the log into several sections.  The anchor structure may be secured in place by ground stakes.   For  making firewood, logs can thus be split first, then blocked.  The wedge may alternately be set in the side of a tree stump with the anchor structure supported in a cavity excavated on one side thereof to split the stump for facilitating its removal.

Abstract: ABSTRACT      A monostable, solenoid-operated valve in a passage which bypasses the drilling fluid pressure drop across a drill bit at the lower end of a drill string in a well opens and closes in response to downhole conditions to create pressure pulses in the drilling fluid.  The valve is urged toward a closed position by drilling fluid pumped through the drill string.  A larger force is required to open the valve than to hold it open.  Current supplied to the solenoid to open the valve is thereafter reduced to a value sufficient to hold the valve open.  The solenoid is de-energized to close the valve.

Abstract: IMPROVED TUBE CUTTING APPARATUS                   ABSTRACT A ram driven tube cutting apparatus of the double cut type in which sections of tubing are suc-cessively severed from a continuous length thereof by a notching cut followed by a severing cut, includes improved mechanism for clamping the tubing during the cutting process.  A pair of opposed, complemental die jaws are mounted on slides controlled by spaced cam followers carried by the slides.  A reciprocating wedge cam engages and forces the cam followers apart to move the slides thereby closing the jaws on the tubing.  One of the cam followers comprises a roller mounted on an eccentric shaft which may be selectively rotated to adjust the clearance between the die jaws. The other cam follower is spring loaded toward the cam within a slide mounting provided in its slide and automatically shifts to an overload position to avoid damage to the mechanism when foreign objects become lodged between the die jaws.  Each of the die jaws consists of a pair of die jaw portions having spaced, opposed forces defining a slot through which  a severing blade may pass.  The die jaw portions are removably mounted on the slides by bolts anchored with trap nuts slidably confined within a T-shaped passageway  in the slides to permit adjustment of the spacing between opposed  faces of the die jaw portions.

Abstract: Heat Exchanger Plate Having Distortion Resistance Uniform Pleats Abstract A heat exchanger plate has undulatory pleats for forming fluid flow passages on opposite sides of the plate.  The heat exchanger plate is improved by providing the side walls of each pleat with a uniform slope.  By this arrangement, the plate is provided with improved distortion resistance and fluid flow capacity.  Apparatus for forming the pleated plates is disclosed using a pair of non-uniform donative fluid passage forming blades mounted for relative oscillatory movement with respect to a recipient fluid passage forming blade wherein the clearance between each blade is uniform throughout the entire length of each blade. By making the blade clearance constant the slope of pleat sidewalls may be constant even though each pleat follows a curvilinear path.

Abstract: "Cigarette quality control device"     ABSTRACT     The invention relates to the devices for any cigarette quality control to be effected at the hopper (1) for the cigarette feeding to a cigarette-packing machine. In its lower section, this hopper comprises a plurality of cigarette-guiding down channels (2) set side by side, which are adapted for containing each only one individual pile of cigarette (S) so as to allow them to slide downwards, and which are directed toward an underlying chamber within which a cigarette batch consisting of at least one layer of ciga-rettes set side by side will be formed. By a pusher member (7) or the like, this cigarette batch will be ejected therefrom at intervals, to be transferred to the cigarette-packing machine. Near each one of the said cigarette-guiding channels (2), cigarette-inspection sensor means are provided either on one or on both of the cigarette end sides, the said sensor means being responsive to the cigarette property to be checked and controlling cigarette ejection means which are adapted for ejecting and discarding any defective cigarette found out by the cigarette-inspection sensor means. In each one of the cigarette-guiding channels (2) there is provided, according to the invention, a rotary cigarette-transfer device (3) that separates the respective cigarette-guiding channel (2) into one upper section (12) and one lower section (22). The cigarette-inspection sensor means (18) are arranged in correspondence of the upper section (12) of the cigarette-guiding channels (2) and are associated with at least one cigarette position in this upper section (12) of said channels. Every rotary cigarette-transfer device is so constructed, and so operated by the respective cigarette inspection sensor or sensors (18), that it transfers every regular cigarette (S) from the upper section (12) to the lower section (22) of a cigarette-guiding channel (2), whereas it moves any defective cigarette (S1) into an intermediate position where the cigarette-ejection means are provided.
