Abstract: ABSTRACT OF THE DISCLOSURE:         A colony-stimulating factor having definite physical and chemical properties and a function of stimulat-ing activity on human bone marrow cells to proliferate and differentiate, thereby forming granulocyte colonies, is obtained from human urine by concentrating the urine with respect to proteins contained therein by adsorption chromatography with silica gel, salting out with ammonium sulfate and other means, then removing impurities by adsorption on cation exchanger, and further purifying by ion exchanging chromatography on anion exchanger, gel filtrating chromatography with highly crosslinked gels, affinity chromatography with sugar affinitive adsorbents and electrophoresis.  This substance is stable in the presence of a stabilizer such as albumin or urinary proteins, against heat-treatment of virus-inactivation and can be used as a leukopenia curative which is precluded from fear of virus-infection.

Abstract: ABSTRACT OF THE DISCLOSURE           A thermal energy scavenger assembly including a plurality of temperature-sensitive wires made of material which exhibits shape memory due to a thermoelastic, martensitic phase transformation.  The wires are placed in tension between fixed and movable plates which are, in turn, supported by a pair of wheels which are rotatably supported by a housing for rotation about a central axis.  A pair of upper and lower cams are fixed to the housing and cam followers react with the respective cams. Each cam transmits forces through a pair of hydraulic pistons. One of the pistons is connected to a movable plate to which one end of the wires are connected whereby a stress is applied to the wires to strain the wires during a first phase and whereby the cam responds to the unstraining of the wires during a second phase. A housing defines fluid compartments through which hot and cold fluid passes and flows radially through the wires whereby the wires become unstrained and shorten in length when subjected to the hot fluid for causing a reaction between the cam followers and the cams to effect rotation of the wheels about the central axis of the assembly, which rotation of the wheels is extracted through beveled gearing.  The wires are grouped into a plurality of independent modules with each module having a movable plate, a fixed plate and the assiciated hydraulic pistons and cam follower.  The hydraulic pistons and cam follower of a module are disposed at ends of the wires opposite from the ends of the wires at which the same components of the next adjacent modules are disposed so that the cam followers of alternate modules react with one of the cams and the remaining cam followers of the remaining modules react with the other cam.  There is also included stress limiting means in the form of coil springs as sociated with alternate ends of the wires for limiting the stress or strain in the wires.

Abstract: PRE-FORMED WEAR PADS FOR DRILL STABILIZERS         ABSTRACT OF DISCLOSURE   Hard surfacing the wear surfaces of rib-type stabilizers formed on drill strings by welding pre-formed wear pads upon the stabilizers. The pads are made of flattened, steel tube-like, thin wall, sheaths, filled with a matrix formed of hard carbide particles and a soft alloy binder. After welding each pad in place, its exposed wall section is removed to now expose a flat, accurately dimensioned, smooth carbide-binder hard wear surface. When the wear surface becomes worn, the worn pads may be removed by breaking the weldings and then replacing the pads with new pads welded in their place.

Abstract: Abstract of the Disclosure Melt beads, e.g., magnesium beads, or Mg alloy beads, having a high degree of rotundity, and having a thin coating of sludge or slag ingre-dients, are recovered from entrapment in a friable contiguous material of sludge or slag material by (a) a primary milling of the friable matrix in a hammer mill or impact mill, (b) screening the material to collect the desired particle sizes, (c) attriting the material in a secondary milling operation to further, and gently, grind sludge material from around the beads, and (d) separating the rotund beads from the pulverized matrix material by using a shape-classifier, such as a slanted shaker table.  The material may be treated before-hand by melting the metal-containing sludge or slag, adding a flux or emulsifier material with stirring to cause dispersion of the metal into a relatively narrow particle size range and then freezing the molten mixture. The invention is especially useful in the case of Mg beads, since Mg beads are malleable and pyrophoric. 26,640-F

Abstract: ABSTRACT OF THE DISCLOSURE     A torque transmitting assembly including three telescopically arranged  shafts is formed with an interlocking ball device which releasably axially locks the shaft members together. The ball device may include one or more balls which are movable radially of an intermediate shaft member, with the balls locking the intermediate shaft member with an inner shaft member when the balls are in a radially inward position and releasing said axial interlocking when the balls are permitted to move to a radially outward position by engagement within a recess of the outer of the three shaft members.  The inner shaft member is formed with a conically shaped attachment member which operates to tend to urge the ball into the recess to release axial interengagement between the inner and intermediate shaft member and to permit the ball to move along the conical surface thereof back to its radially inward position when said locking engagement is to be re-established.  The balls are held within apertures formed in the intermediate shaft member and a spring loaded control ring actuated by the conically shaped attachment member operates to hold the balls in their radially outward position when the shafts are in their telescopically extended state.

Abstract: Modified Slowdown and Braking of an Elevator Car Abstract In elevator systems where the stop and/or slowdown operations are preset for maximum car velocity the stopping and/or slowdown operations are delayed in proportion to the variation from maximum car velocity in order to compensate for the shorter stopping distance required when the car is moving slower than that maximum velocity.  Motor speed is sensed within a revolution to provide a signal which manifests the motor speed.  This signal is referenced to a second signal which reflects the motor speed for maximum car velocity.  The differ-ence between the two signals is a third signal which is used to control delay circuits which delay transmission of stop and/or slowdown signals to the brake and motor in a prescribed relationship to the magnitude of the difference between the two signals.

Abstract: ABSTRACT OF THE DISCLOSURE     Composite panelling of upper and lower metal skins with side configuration for interlocking and a rigid foam core are continuously made by feeding separate upper and lower skin panels secured together by preassembled rigid foam end dams continuously past a foam station having a small height mixing head mounted on cross slides to lay down a zigzag pattern of foam between the skins, with the first and last transverse run of foam being parallel to the ends of the skins.  A mixing head is such that valves are located within the head so that the two foamable chemicals do not contact each other until they are fed into the mixing chamber wherein a mechanical mixer mixes them immediately prior to being deposited, which mechanical mixer and valves are of minimum height and fully insertable within the molding space between the skins.  A drive motor for the mixer is located in the main body supporting the mixing head, which main body does not enter into the mold cavity.  The valves and cross slide are operated auto-matically, and if there is too long a delay between foam deposits, the chemical valve faces, mixing chamber, mechanical mixer and other parts exposed to the mixed chemicals will automatically be flushed with a solvent and air.
