Abstract: NOVEL POLYVINYL CHLORIDE SUSPENSION              POLYMERIZATION PROCESS AND PRODUCT     ABSTRACT OF THE DISCLOSURE    A polyvinyl chloride having high bulk density and enhanced plasticizer absorption is produced by suspension polymerization of vinyl chloride monomer and comonomers wherein the initial suspension of ingredients is generated such that the oil phase droplets formed in the suspension are compositionally equivalent with respect to initiator, and the level of suspending agent and agitation are chosen to substantially preclude agglomeration of resin particles throughout the reaction, thereby producing resin wherein the resin grain size distribution results directly from the oil phase droplet distribution created at or near the start of the reaction.  The process is conducted under conditions so that the polymerization is commenced before the final distribution is established.  In this manner, seed particles of resin are produced from the vinyl monomer prior to establishing the final particle distribution.  The seed particles can be formed (1) by first conducting the process at low speed agitation, followed by increasing the speed of agitation so as to distribute the resin seed particles in the droplets of vinyl monomer, or (2) by preheating the aqueous medium prior to mixing with the vinyl mononler phase so as to initiate polymerization and formation of seed particles before the vinyl monomer droplets achieve their ultimate droplet size.  The result of the processes of the invention is a polyvinyl chloride polymer or copolymer that has high bulk density and enhanced plasticizer absorption.  A further benefit of the process is that resin deposition on the interior surfaces of the reactor is essentially eliminated.

Abstract: DEVICE FOR THE UNDERWATER MEASUREMENT OF THE HARDNESS OF A            VERTICAL  WALL  OF  THE  PARTITIONING OF  THE  CORE  OF  A   PRESSURIZED WATER NUCLEAR REACTOR                 ABSTRACT OF THE DISCLOSURE The invention relates to an underwater measuring device of the hardness of a vertical wall of the parti-tioning of the core of a pressurized water nuclear reactor. The device comprises a hollow pole for  the  manipulation from the edge of the pool of  the  reactor  of  the  pole in vertical position.   A body fast to the  pole  at  its lower end contains a first chamber in  which  is  mounted a movable piston bearing support means intended  to  come into contact with  walls  at  right  angles  and  a  second chamber in which is movably mounted a second piston bearing a hardness measuring head designed to form an impression on the wall opposite one of the walls.   Hydraulic fluid supply means for the chambers and conductors pass through the  hollow  pole.    The  conductors  are  connected to  a measuring station.  The invention is applicable particularly to determining the influence of irradiation on the walls of the partitioning of a nuclear  reactor,  after a certain period of operation.

Abstract: ABSTRACT OF THE DISCLOSURE         Method and device for operation of a heating plant comprised in a heating system which works with circulation of air.  A partial flow of the consumed air in the heating system is supplied to a heat exchanger for heat exchange with intake air coming from outside and with a return flow of circulation air from the heating system.  After passage through the heat exchanger the mixture of intake air and return air is fed as heat delivering medium to the evaporator in a circulation heat pump.  The quantity of air circulating through the heat pump is kept greater than the partial air flow which is exhausted from the heating system via the heat exchanger.  With increas-ing demand for energy the partial flow is exhausted by means of a suction fan and can, in addition, be mixed with the flue gases from a preferable water-carried heating boiler.

Abstract: ABSTRACT OF THE DISCLOSURE     A display control unit is disclosed which is capable to change the processing form of a central processing unit (CPU) for increased processing speeds.  In this display control unit, when the execution time of its display operation is reduced by reading out data in a source area from a memory unit and then writing the read-out data sequentially into a destination area, a predetermined period of time before the beginning of a vertical or horizontal retrace, the CPU is interrupted so that the CPU can omit its confirmation as to whether a video CPU has completed its previous processing.  Also, in this display control unit, an updating processing of color specification in display data can be performed at increased speeds, only desired dots on a display screen can be logically operated, a form or an object having a solid body on a transparent background within a source area can be transferred at higher speeds, and an expansion memory can be used as a "kanji(chinese character)"    ROM (pattern memory) or the like.

Abstract: HAND VACUUM CLEANER A hand vacuum cleaner is provided comprising a lightweight motor housing containing a revolving brush. A bag assembly is selectively separable from the housing and is sealable to the housing with an elastomeric retaining ring including a sealing and retaining bead for reception in a recessed slot area of a housing bag attachment collar. A fan is mounted to the motor on a motor shaft locking surface including a wall portion tapering towards the fan. The shaft is in locking cooperation with a mating fan bore locking surface including a wall portion tapered for close reception of the motor shaft locking surface. A shaft extension is threadedly received on the motor shaft and is urged into engagement against the fan by resistance of a revolving brush operated by a belt received on the shaft extension which continually tightens the shaft extension to the motor shaft and fixes the fan to the motor shaft. A stone shield is circumferentially spaced about the fan whereby the stone shield blocks items impinging against the housing from the fan from damaging the housing. The housing further includes an air deflector substantially received in the bag assembly having a terminal end portion disposed radially inwardly from the housing outer wall whereby the deflector directs the working air to facilitate greater storage of vacuumed dirt in the bag and prevent heavy objects received in the bag from rolling back into the housing and contacting the fan. A nozzle guard is mounted on a housing nozzle including brush bearing housing retaining elements disposed for a deflecting interference fit to the bearing housings whereby the brush is positively retained in the nozzle to minimize vibrational movement.

Abstract: Electrocardiogram Signal Processing Apparatus ABSTRACT               An electrocardiogram signal processing apparatus comprises three elements:   1. an analog-to-digital converter. 2.  a first processor for processing a digital signal. 3.  a second processor for detecting an onset of the QRS complex. 4.  a third processor for recognizing a delta wave.          The analog-to-digital converter converts an input electrocardio-gram signal into a digital signal.  The first processor processes the digital signal, which is the output of the analog-to-digital converter, by secondary differentiation.  The second processor detects an onset of the QRS complex in accordance with an output signal from the first processor.  The third processor recognizes a delta wave which is peculiar to an electrocardiogram of the Wolff-Parkinson-White syndrome in accordance with the digital signal, the secondary differentiated signal delivered from the first processor, and the onset location of said QRS complex.
