Abstract: ABSTRACT OF THE DISCLOSURE            Rotary regenerative heat exchange apparatus in which a rotor of heat absorbent material is alternately exposed to a heating fluid and to a fluid to be heated.  The rotor is surrounded by a housing having a sector plate at opposite ends thereof adapted to separate the heating fluid from the fluid to be heated.  The apparatus is provided with control means that intermittently drives a sector plate into a sealing relationship with the adjacent edge of the rotor after which a predetermined reference point on the rotor activates a sensor to move the sector plate away from the rotor to permit freedom of movement therebetween.

Abstract: ABSTRACT OF THE DISCLOSURE A variable speed belt drive is preferably used as an accessory drive for an automotive vehicle, and has an input shaft connected to the engine and an output shaft connected to an accessory.  Power is transmitted from the input shaft to the output shaft through a vari-able pitch pulley on the input shaft, an endless belt, and a variable pitch pulley on the output shaft.  A torque-responsive mechanism is connected to the pulley on the input shaft to decrease the diameter of the pulley as the load increases; and a speed-responsive mechanism is connected to the pulley on the output shaft to increase the diameter of the pulley as the speed of the output shaft increases.  The torque-responsive mechanism is operated by a spring acting both in compression and in torsion, and is effective to partially overcome the speed-responsive mechanism when a high torque load is applied to the accessories thereby at least preventing high torque from causing a drop in speed of the accessories.

Abstract: ABSTRACT OF THE DISCLOSURE            An electrostatographic developer mixture comprising finely-divided positively charging toner particles electrostatically clinging to negatively charging carrier particles. The toner particles comprise a resin, a colorant, and a charge inducing material selected from (1) a long chain hydrazinium compound and (2) an alkyl pyridinium compound. The carrier particles comprise core particles having a coating of fused thermoplastic resin particles wherein the carrier particles are prepared by dry-mixing the core particles with thermoplastic resin particles until the resin particles adhere to the core particles. The mixture of core and resin particles are heated to between 320°F. and 650°F. for between 20 and 120 minutes so that the resin particles melt and fuse to the core particles. The developer mixture is employed to develop electrostatic latent images.

Abstract: ABSTRACT OF THE DISCLOSURE    Starch ether derivatives are prepared by reacting a starch base with N-(2-haloethyl)iminobis(mthylene)diphosphonic acid or with a H-(alkyl)-N-(2-haloethyl)aminomethylphosphonic acid.  The derivatives contain aminophosphonic acid groups (or their salts) as zwitterion substituents which consist of either one or two anionic methylene phosphonic acid groups bound to a cationic nitrogen,  Their cationic or anionic characteristics may be increased by introducing suitable cationic or anionic groups either by simultaneous reaction with the aminophosphonic acid reagent or by consecutive reaction either prior to or subsequent to the aminophosphonic acid reaction.  They are especially useful as pigment retention aids in papermaking processes.

Abstract: ABSTRACT           "METHOD OF MANUFACTURE OF BRUSH COMPONENTS" Methods of manufacturing brush components arc disclosed in which a plurality of predetermined lengths of brush bristle formed of synthetic resinous material are fed from a supply into the nip of at least one pair of endless haul-off belts so that the bristles are arranged substantially uniformly and parallel to each other with their ends in line.   In one construction a single pair of haul-off belts having a width which is less than the bristles is used, the bristles projecting beyond the sides of the belts, and the thus formed bristle array is fed into an extruder whereupon a plastics material is extruded over the projecting ends of the bristles to hold them together and/or the ends are fused together, the resultant product, on emerging from the ends of the belts, then being slit centrally to provide two endless components. In another construction, two spaced pairs of belts are used to advance the bristles into an extruder and plastics material is extruded down the centre of the bristles either from each side or in sufficient amounts to penetrate between the bristles completely, whereupon on emerging from the belts the bristles are either folded about the central extrusion through 180°, whereupon the extrusion is allowed to cool, or are slit centrally of the extrusion to provide two components.    In all the constructions, the bristles are heated prior to or during the extrusion, and hence soften or are fused together.

Abstract: Abstract of the Disclosure A device that forms smooth cylindrical surfaces along a log being moved longitudinally past a cutting station.          The device includes a feed conveyor that moves successive logs longitudinally past a cutting station.  A planetary cutting head drive is situated at the cutting station.  The drive rotates a cutting head about a first planetary axis spaced from the log axis.  It also revolves the cutting head about a stationary second axis that is coaxial with the log axis.  A smooth cylindrical cut is thus made about the periphery of the log as it is moved longitudinally parallel to its axis.

Abstract: Abstract of the Disclosure A new fluxed pellet for use in iron-making is obtained by mixing and indurating about 1 to about 20%,by weight of the pellet, of ground melt shop slag fines with similarly ground iron ore concentrate, so as to achieve particular ranges of silica content, CaO/Si02 ratio, and MgO content.  The melt shop slag fines have been considered a waste material, but contain signif-icant slag and metal values.  The slag is already in calcined form for an energy saving as compared to the use of limestone and dolomite, and is already somewhat divided for a saving in grinding energy.  The resultant basic pellets have better furnace properties than the acid pellet produced without slag addition.

Abstract: Combination Reversing Valve and Expansion Device for a Reversible Refrigeration Circuit Abstract Apparatus is disclosed for serving as both a reversing valve and an expansion device in a refrigeration circuit.  A valve gate having passageways to direct refrigerant between the indoor and outdoor heat exchangers to effect the function of a reversing valve is disclosed.  In addition, the valve gate has multiple flow restriction devices which are selectively incorporated within a refrigeration circuit between the indoor heat exchanger and the outdoor heat exchanger to effect the appropriate amount of flow restriction dependent upon the mode of operation of the unit. These two functions may be incorporated into a single valve or they may be separated such that the separate functions are performed by separate valves.  A cylindrical valve gate and multiple passageways for connecting the appropriate lines in a refrigeration circuit are described.  The valve is rotated by a combination of an electromagnet spaced about the valve gate and a permanent magnet located within the valve gate.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention provides a novel means for the administration of a therapeutically effective ingredient in the form of a rectally applicable medicament capsule, in which the otherwise unavoidable extreme variation in the absorbability of the effective ingredient among the individuals rectally treated with the capsules is minimized.  It has been unexpectedly found that, when the effective ingredient is contained in the capsule in the form of a liquid medicine, the osmotic pressure of the liquid content plays a very essential role in the absorption of the effective ingredient through the rectum and the variation in the absorbability of the effective ingredient among the individuals can be minimized when the osmotic pressure of the liquid content is substantially higher than the osmotic pressure of the rectal fluid with which the capsules are contacted and is in the range of from 350 to 2000m Osm/kg H2O.
