Title: Process for the production of polyvinyl chloride suitable for plastisol preparation
IPC: C08K5/09
Filed: 1965-06-02
Abstract: Polyvinyl chloride suitable for preparing plastisols may be prepared by forming an emulsion from a stable polyvinyl chloride aqueous dispersion and an aliphatic amine salt of a C8- 22 fatty acid or a C8- 22 fatty alcoho in amount of 0.1 to 5 weight per cent based on the polyvinyl chloride, drying said emulsion and comminuting the product obtained.  Preferred acids and alcohols have 10 to 18 carbon atoms, and the emulsion is preferably heated at up to 90 DEG  C. for up to 1 hour before drying, which may be effected by spray drying.
Patent GB-553650-A (GB)
Abstract: 553,650. Gyroscopic apparatus. RASPET, A. June 20, 1942, No. 8505. Convention date, March 17, 1941. [Class 97 (iii)] In a gyroscope instrument whose rotor when spinning is automatically self-balancing, the rotor is mounted on a pivoted frame and carries a centrifugal element connected to the stationary support so as to oppose precession of the gyroscope thereby rendering the response of the instrument independent of the speed of the rotor. As shown in connection with a rate of turn indicator, the rotor 21, Fig. 1, is mounted in a frame 15 pivoted for precession upon a transverse shaft 16. The gyroscope is placed in neutral equilibrium about the shaft 16 by adjusting a weight 19. Chains 30 forming the centrifugal element are attached at one end to the rotor and at the other end to a rotatable disc 31 carried by the stationary frame 12. A motor 22 drives the rotor. The chains in addition to resisting the precession of the rotor also render it selfbalancing dynamically, that is counteracts the effect of any small eccentricity in the weight of the rotor. The armature of the motor 22 is utilized as a magnetic element for actuating an electric precession indicator 59, Fig. 8. For this purpose two pole pieces 50, 51 provided with coils 53, 54 extend into the field of the armature, and the voltage induced in the coils is varied according to their distance from the armature, that is according to the precessional movement about the axis 16. The induced voltages are applied to two rectifiers 56, 57 connected in series with the coils, and a milliammeter 59 is arranged in a shunt circuit so that a predominant voltage in either coil moves the pointer one way or the other to indicate the precession due to a change of direction of the instrument. In a modified circuit, Fig. 9 (not shown), the ammeter is connected in the coil circuit and the resistances are shunted across the ammeter. Instead of using chains 30 as the centrifugal element, flexible wires or ribbons weighted at the middle may be used. The weights may be stream-lined and may constitute most of the rotating mass. The centrifugal element may consist of balls 30c, Fig. 6, on the ends of bell-crank levers 34 pivoted to the rotor 20c and connected by links 35 to a stub shaft 37 rotatable on a fixed support. In a further modification, Fig. 7, the centrifugal element consists of a fluid contained in a flexible bellows 40 secured to the rotor by radial tubes 39 and connected by a chain 41 to a rotatable member 37b.

In a conveyer system of the kind in which wheeled load-carrying trolleys, e.g. T, Fig. 1, are supported on a floor, and each trolley has an upstanding mast 10, 12, engageable with abutment means on an overhead driven chain (not shown), the mast 10, 12 is downwardly retractable against a spring 13 to disconnect the mast from the chain when a roller 16, on an arm 17 pivoted to the trolley and connected by a pin-and-slot connection 17a to the part 12 of the mast, engages a ramp 15 movable into an operative position shown in full lines, at a trolley holding station. The mast has a roller 10a adapted at position A to co-operate with guide rails associated with the drive chain and to be disconnected from the chain at position B. The mast may be moved manually to a disengaged position C by means of a locking bolt 14 as described with reference to Fig. 2 (not shown). The trolley also has a safety bar 18 mounted on an arm 19 pivoted to a bracket 20 on the trolley and connected by a link 21, fixed to the arm 19, and a pin-and-slot connection 22 to the part 12 of the mast, whereby when the bar 18 abuts an obstructing trolley the mast is disconnected from the drive chain. Trolleys are divertable into any one of a number of different branch lines by switch points operable by a selector mechanism. The latter comprises a circular plate 23, Fig. 3, slidable on the mast part 10 into selected positions by a rod 24 having a finger 25 engageable with slots in a selector plate 26 on the trolley. At each of selected stations associated with the switch points and at differing levels corresponding to the settings of the plate there is provided a pair of light sources 27 focused on to a photo-electric cell 28. When both light beams are interrupted by the plate 23 the cell 28 will be effective to give a signal to actuate the associated switch point. The passage of a mast past the light sources will result in the interruption of only one light beam at a time and thus will not cause operation of a switch point.
