Abstract: ABSTRACT OF THE DISCLOSURE Vinyl chloride polymers are chlorinated in a dry, two-step process including treating particulate vinyl chloride with gaseous chlorine at temperatures in the range of -20°C to +150°C, preferably 20-25°C and without the use of radical-forming initiators or radiation for at least about 30 minutes, then increasing the temperature of the reaction to at least 70°C until thermal radical formation occurs.  In the second step the temperature is maintained below the point where the vinyl chloride is apt to agglomerate or discoloration occurs.  This process avoids the use of liquid systems and provides a final product in a dry powder form having an increased dimensional stability.

Abstract: ABSTRACT OF THE DISCLOSURE           Two cup-shaped electrodes respectively defining outer walls of a closed and an open ionization chamber and an insulator wall sandwiched therebetween defining an interior wall of both chambers and carrying both an electrode common to both chambers and a circuit element of a sensing circuit responsive to the relative impedances of the two chambers for indicating the presence of smoke in the open chamber.  Mini-mizing leakage current-increasing factors as moisture, dust, etc., the body of the circuit element is protectively mounted to the insulator wall within the closed chamber by means of a plurality of leads extending through mating holes in the insulator wall with a header surface of the body pressed against the wall.  One of the leads is folded around the edge of a hole in the wall wherein the common electrode is mounted and is squeezed between the insulator wall and a part of the common electrode to make electrical contact therewith.  Some of the leads which extend out of the chamber for connection with external circuitry are sandwiched between an insulator member and the wall and thereby insulated against electrical contact with either of the cup-shaped electrodes.  The insulator member is integrally formed with the insulator wall by cutting a portion thereof away from the wall to form the electrode mounting hole and folding it to overlie the leads and the wall.

Abstract: ABSTRACT OF THE DISCLOSURE             A coin slide apparatus which includes a housing for mounting the apparatus to the machine, a coin slide assembly, a guideway in the housing for the coin slide assembly to operate within, and coin authenticating apparatus on the housing.  The coin slide assembly is reciprocally operable in the guideway from an extended coin receiving position through coin measuring and coin ejection positions to a position for initiating operation of the machine.  The movable slide assembly comprises three main members:  an upper slide plate, a center body portion, and a latch plate.    The upper slide plate is formed to include the operating handle at one end and has coin receiving slots of a pre-determined size.  The center body portion gives the slide assembly the necessary thickness to support coins on edge and serves as a storage area for blanking members and coin inserts which are used to convert the apparatus from one combination of coins to another.  The latch plate mates with latch arms, which are mounted on the housing, to prevent operation either without coins or with spurious coins.  A bridge portion mounts a plurality of abutments, one above each latch arm, which cooperate with a cam on each latch arm to provide a predetermined coin measuring space therebetween.          At least one of the abutments forms part of a preadjustable abutment assembly.  When the preadjustable abutment assembly is moved vertically in combination with movement of the coin insert, the coin slot and the predetermined coin measuring space are converted from one denomination to another.

Abstract: ABSTRACT OF THE DISCLOSURE            Method and equipment are disclosed for forming fibers from attenuable material such as molten glass, by the use of high velocity whirling gas currents or tornadoes.  Attenuation is preferably effected in two stages, the first of which utilizes a pair of high velocity whirling currents or tornadoes formed by delivering a gaseous jet through a jet guiding device of trough-like form which is concavely curved, thereby developing a pair of counter-rotating tornadoes, with a zone of laminar flow therebetween, a stream of the attenuable material being delivered to the jet in the zone of laminar flow.  A larger gaseous blast is also utilized being directed in a path intercepting the path of the jet to provide a zone of interaction also characterized by a pair of counter-rotating tornadoes, the stream of attenuable material being carried by the jet into the blast thereby subjecting the material to a second stage of attenuation in said zone of interaction.

Within the enclosure of the fuel bowl are positioned a pair of injectors which are adapted to inject pulsed portions of fuel through a sonic nozzle and into the air intake throat of the throttle body. The injection of pulses of fuel into the throat is timed in accordance with the sensing of the crankshaft reaching a position of 15° before top dead center to enhance the distribution of fuel charge from cylinder to cylinder. The fuel pressure within the bowl is controlled by a pressure regulator positioned within the enclosure formed by the bowl and housing cover, the diaphragm closing the bowl also forming the diaphragm for the regulator. The pulses to the injectors are controlled by an electronic control unit in response to sensed engine conditions.

Abstract: ABSTRACT OF THE DISCLOSURE          A solid, monolithic bicycle tire made of urethane rubber with a cured hardness of from 60 to 70 Durometer A.  The tire is formed with a pair of laterally spaced bead shoulders that seat on the bead seats of the wheel rim, and is generally triangular in cross-section, with radially outwardly con-verging, slightly concave side walls that merge into a rela-tively narrow tread section.  A circumferential, arch-shaped tunnel is formed in the inner side of the tire between the bead shoulders, and the material between the tunnel and the converging outer surfaces forms narrow, inwardly inclined side walls that are compressed when pressure is applied radially inwardly against the tread.  The inclination of the side walls results in a substantial amplification of the deflection of the tire under impact loads, as compared to the deflection of similar-thickness side walls that are not inclined, but instead, are parallel to one another.  As the tire is compressed under load, the side walls tend to collapse inwardly, causing the bead shoulders to grip the wheel rim  with increasing force, thereby resisting any tendency of the bead shoulders to climb up over the edge of the wheel rim.  The tire is also held firmly on the rim by means of a circumferential bead-locking insert that is placed in the bottom of the wheel rim before the tire is mounted.  Foot extensions at the bottom edges of the tire side walls are then pressed down into the space between the wheel rim and the insert, and the insert acts to hold the foot extension and bead shoulder firmly against the wheel rim so as to resist any tendency of the foot extension or bead shoulder to climb.
