Title: Improvements in or relating to a process for the preparation of polyvinyl chloride
IPC: C08F14/06
Filed: 1956-04-17
Abstract: Vinyl chloride, alone or with another ethylenically unsaturated monomer, is polymerized, preferably continuously, in aqueous emulsion at a pH of 8.5 to 11 whilst introducing hydrogen peroxide and using as the emulsifier a monocarboxylic acid salt having from 8 to 22 carbon atoms in the molecule.  The other monomer may be vinyl acetate, vinylidene chloride, or an acrylic or methacrylic acid ester.  Emulsifiers mentioned are the salts of lauric acid, e.g. ammonium laurate, stearic, myristic, oleic, linolinic, and palmitic acids.  The polymers may be separated from the resultant polymer latex by coagulation with organic or inorganic acids, and if desired further treated with a solution giving an alkaline reaction.  After the alkaline treatment the coagulate may be further purified by heating and passing it through a screw press to reduce its water content and subsequently grinding the polymer to a fine powder.  The polymer may also be recovered by spray drying in hot air at a temperature of 140 DEG  to 160 DEG  C.  The powdered polymer may be used in plastisols, e.g. suspended in dibutyl phthalate, tricresyl phosphate, or dioctyl phthalate.

Abstract: 1,086,102. Packaging-machines. VERPACKUNGS UND SCHOKOLADENMASCHINEN DRESDEN VEB. March 17, 1966, No. 11743/66. Heading B8C. A machine for packaging bakery products such as biscuits into bags lying on their sides consists of a bag-supply station, a bag-filling station, a pre-folding station, a turning device for raising the filled bags from the horizontal to an upright position and a bag-delivery station. As described (Fig. 1, not shown), a bag 3 is withdrawn from a magazine (5) and inserted into a U-shaped entraining pocket 1 of a conveyer chain 2. The bag 3 on the conveyer chain 2 then passes to a filling station, where a row of biscuits (15) is conveyed forward on a slideway (12) (Fig. 2, not shown) by bars (14) connected to an endless chain (13). At the end of the slideway (12), the row of biscuits (15) is pushed by an inserter (6), operated by contact of a lever arm (19) with a cam (not shown), on to a collector plate (16). The inserter (6) is returned and a second row of biscuits (15) pushed on to the collector (16), whereupon the inserter (6) continues its insertion movement to push the two rows into the open end of the bag 3 previously opened by a bag opener (7). The filled bag is next conveyed to a prefolding station (8) where the opening of the bag is folded up to facilitate raising of the bag at a turning device 9, where the bottom of the bag, protruding beyond the entraining pocket 1, comes to rest on a receiving plate 22 (Fig. 3) which is pivotable through 90 degrees on a spindle 23. Directed towards the bag opening and connected to the spindle 23 is a pivot arm 24, the end of which is pivotally connected to a clamp lever 25 which presses against a curved slideway 26 by means of a spring 28. The bag opening rests between the clamp lever 25 and slideway 26, the bag being raised by pivoting receiver plate 22 until a cam roller 32 on the cam lever 25 connects with a cam piece 30, whereupon the spring force of the spring 28 is overcome to cause the clamp lever 25 to be secured to the pivot arm 24 by means of a magnet 29. The bag opening is thus released and the upright bag stands on a delivery plate 33. The pivot arm 24 returns and when the cam roller 32 connects with a cam piece 31, the magnetic adhesion is released to once more cause the cam lever 25 to press against the curved slideway 26 by means of the spring 28. The upright bag is finally moved from the delivery plate 33 to a delivery belt (10) on which it passes through a bag closing station (not described). The entraining pockets 1 and the bars (14) are adjustadle to deal with different sized bags and biscuits, respectively.

Abstract: 125,473. Hargreaves, F. J., and Blackburn Aeroplane & Motor Co. Aug. 21, 1916. Steering and balancing.-A control device for aircraft comprises means for balancing wholly or in part the air pressure on a control surface pivoted in front of its centre of pressure, the device being also adapted to hold the control surface resiliently in the position that it occupies at the moment when the pilot takes his hand from the control lever. Fig. 1 shows diagrammatically a device in which a spring is used to balance the air pressure, but the thrust of the screw, or the air pressure on an aerofoil or on a pivoted section of the sustain. ing surface, may be utilized. A lever a pivoted at b is geared to the control surface, and its outer end d is acted upon by a spring e through the open frame f, c<1> carrying a rack c concentric with d. The spring e normally acts through the dead centre of the lever a, but acts with increasing leverage when the control surface is displaced. The point b of the lever is adapted to be locked to the rack c at any point so that the spring e then acts to resist any displacement of the lever a from the position it occupies at the moment of locking. Fig. 5 shows a modification in which the spring e acts through a cable passing between rollers on a block s which slides over a rack r to which it can bo locked. Fig. 6 shows a modification in which the lever a is pivoted at d and the end b is connected to the spring e by a link t guided as shown. The frame c<1>, f or the block s and rack r may be used with this modification. In another modification, a lever similar to that shown in Fig. 6 is pivoted at a point between its ends. Fig. 3 shows a locking-device comprising five teeth y arranged side by side in staggered relation, the teeth being formed on plates j<1> having slots threaded over a pin o in a stirrup p connected by a Bowden wire to a grip lever on the control pillar.
