Patent GB-589266-A (GB)
Title: Improvements in or relating to indicator control means suitable for use with totalisators, score indicators or the like
IPC: A63B71/06
Filed: 1945-03-21
Abstract: 589,266. Operating clutches. DEGEN, A. A. C. March 21, 1945, No. 7115. [Class 80 (ii)] [Also in Group XXXVIII] In a control system for the indicators of an electric totalisator system &c. a constantly rotating driving member tends effectively to engage a driven member associated with the indicator, at one or more positions in a rotation but is prevented from doing so if the position of the member corresponds with that of the distant aggregator &c. in accordance with which the indicator is to be controlled. As shown, the driven member is not directly geared to the indicator but controls it by a mechanical follow-up arrangement. Each indicator is controlled by a member 18, Fig. 4, slidably mounted on a continuously rotating shaft 14 and spring-pressed against a driving member 16. A commutator arm 26 mounted on shaft 14 engages in succession a number of contacts each connected to the contacts of remote controllers or aggregators. When arm 26 engages the contact connected to the aggregator contact on which wiper 28 is set, a solenoid 23 is energized and moves contact member 18 away from the driving member 16. If the control member and aggregator are in corresponding positions, the solenoid is energized at the moment when notch 17 comes into alignment with pin 19 and thus prevents engagement of the two. When the solenoid is de-energized, notch 17 has passed pin 19 and member 18 remains stationary. If, however, the member 18 and the aggregator are not in corresponding positions, pin 19 engages notch 17 when the two come into alignment and the control member is carried around until agreement is reached when solenoid 23 is energized. Member 18 is moved so that locating pins 20 engage holes in a stationary ring, thus preventing further rotation. A gear wheel 21, Fig. 1, mounted on member 18 engages another gear 7 upon which is mounted a cam 8 which normally holds pawl 4 out of engagement with a continuously rotating notched disc 6. When the clutch control member 18 and thus 8 are moved, pawl 4, mounted on gear 1 which drives the indicator, engages disc 6, so that the indicator is driven until pin 9 engages cam 8 and disengages the pawl. Another pawl 11 then engages a stationary notched disc to prevent further rotation of the indicator. The chain or gear wheel driving the indicator may be connected directly to the clutch control member. In a further modification, Fig. 5, the commutator has two arms 26a and the solenoid is energized through either of segments 36, 37 at the aggregator and one of contacts 30, 32. In the position shown the control member and aggregator are not in synchronism and member 18a is driven round until cam 33 operates to cause switch arm 31 to engage contacts 30 so that solenoid 23 is energized when the commutator arm engages the appropriate contact. In Fig. 6 (not shown) the clutch control member has a pawl which engages a notch in a driving member, but is disengaged by action of the solenoid.

Title: Dispersion polymerisation.
Inventor: SMITH HILARY MUIR
IPC: C08F2/08
Filed: 1966-02-18
Abstract: 1,178,233. Polymer dispersions. IMPERIAL CHEMICAL INDUSTRIES Ltd. 10-Feb., 1967 [18 Feb., 1966], No. 7275/66. Addition to 941,305. Headings C3G and C3P. A dispersion of polymer particles in an organic liquid is made by polymerizing an ethylenically unsaturated monomer in the presence of a stabilizer comprising an anchoring component which becomes associated with the surface of the polymer particles as they are formed and a pendent chain-like component which is solvated by the organic liquid and provides a steric stabilizing sheath around the particles, the polymer being one which is insoluble in its monomer and the organic liquid of the dispersion being excess monomer. Suitable monomers are vinyl chloride, vinylidene chloride, acrylonitrile, and methacrylonitrile. In one embodiment, the stabilizer is formed in situ by dissolving a stabilizer precursor, e.g. polylauryl methacrylate, polyisobutylene or polyisoprene in the monomer, e.g. vinyl chloride and grafting a minor portion of said monomer on to the precursor during the polymerization process. In Example 1, vinyl chloride is polymerized using diisopropyl peroxydicarbonate as catalyst, in the presence of a stabilizer precursor comprising a copolymer of tertiary butyl methacrylate and methacrylic acid which has been reacted with allyl glycidyl ether. A further amount of precursor is added over a period of time. On removal of excess monomer, dry particulate polyvinyl chloride is obtained. Similarly, polyvinyl chloride is produced in Example 2, using as stabilizer precursor a lauryl methacrylate-methacrylic acid copolymer reacted with allyl glycidyl ether. In Examples 3 and 4, acrylonitrile is polymerized using azodiisobutyronitrile as catalyst and as stabilizer precursor, (3) a methyl methacrylate-glycidyl methacrylate copolymer reacted with a selfpolyester of 12-hydroxy stearic acid or (4) an ethyl acrylate-glycidyl methacrylate copolymer reacted with methacrylic acid.
