Title: Improvements in electric circuit-breaker devices
IPC: H01H33/16
Filed: 1953-05-04
Abstract: 730,346. Protective cut-out arrangements; conducting liquid switches; controllers. BENCHEMOUL, N. R. May 4, 1953 [May 7, 1952], No. 12350/53. Classes 38 (3) and 38 (5). In a circuit-breaking arrangement for an apparatus 1, Fig. 1, supplied from terminals 2, the increase of resistance of a liquid resistance apparatus 3 in the event of excess current conditions causes a drop in the voltage across the winding 14 of a circuit-breaker 15 which opens to interrupt the supply. The apparatus 3 comprises a small chamber 7 enclosing electrodes 4, 5 and communicating via small passages 8, 9 with a vessel 10, the chamber and vessel being filled with conducting liquid. Under normal conditions, the heat evolved by the current passing through the liquid in the chamber 7 is dissipated by the circulation of liquid through the passages, but under heavy overload conditions, the liquid in the chamber 7 is vaporized and the resulting considerable increase in resistance causes the drop in voltage across the winding 14 and reduces the current flowing in the circuit so that circuit-breaker does not have to interrupt the full overload current. Under moderate overload conditions the slow vaporization of the liquid may result in an alternate rise and fall in the resistance of the apparatus 3 without causing the opening of the circuit-breaker 15. This condition may be indicated by an incandescent lamp 43 in series with the winding 14 or by a discharge lamp 44 in series with a resistance 45. A low resistance 46 may be connected across the circuit on the operation of a press-button switch 47 to cause the opening of the circuit-breaker. The circuitbreaker 15 may be closed by depressing a pushbutton 17 or by suitable electromagnetic means. In a modification, Fig. 4, the apparatus 3 may be housed within the container 18 of a motor starting liquid rheostat 19 which has a movable rotor 20 with interconnected electrode sectors 25, enclosed in a fixed casing which has electrode sectors 27. In this modified arrangement the apparatus 3 not only causes the opening of the circuit-breaker under overload conditions as described above, but also in the event of the liquid in the container 18 reaching too low a level or too high a temperature. In a polyphase arrangement, Fig. 7 (not shown), two (or more) superposed chambers 7 may be provided in a common vessel and have Intercommunicating passages so that any vapour produced rises to the uppermost chamber. Fig. 9 (not shown) illustrates a two-phase four-wire arrangement. Specification 718,320 is referred to.

Title: Production of esters
IPC: C08K5/12
Filed: 1960-04-08
Abstract: Plasticizers for polyvinyl chloride and copolymers of vinyl chloride comprise phthalyl glycolate esters of very low volatility having the general formula <FORM:0931781/IV(a)/1> in which R is an alkyl group having at least five carbon atoms or an aralkyl group, and R1 is an alkyl group which contains at least five carbon atoms when R is an alkyl group or at least six carbon atoms when R is an aralkyl group. When used for vinyl chloride resins, 20 to 300 parts by weight of plasticizer is employed per 100 parts of resin.  These plasticizers are suitable for incorporation in vinyl chloride resin compositions used for wire coating at 90 DEG C., about 40 to 60 parts by weight of plasticizer per 100 parts of resin being employed.  For the preparation of the plasticizers (see Group IV(b)).  Copolymers referred to are those of vinyl chloride with vinyl acetate, methyl methacrylate, diethyl maleate, dibutyl maleate and vinylidene chloride.ALSO:Phthalyl glycolate esters having the general formula <FORM:0931781/IV(a)/1> wherein R is an alkyl group having at least five carbon atoms or an aralkyl group, and R1 is an alkyl group which contains at least five carbon atoms when R is an alkyl group or at least six carbon atoms when R is an aralkyl group containing seven carbon atoms, are produced by heating the appropriate alkyl or aralkyl half-ester of phthalic acid with an alkyl haloacetate XCH2COOR1 (where X is Cl, Br or I) in the presence of a tertiary aliphatic or alicyclic amine.  In Example 1, phthalic anhydride is reacted with decyl alcohol to obtain decyl acid phthalate.  This half-ester is heated to 80 DEG C., and triethylamine is added during a period of seven minutes, after which decyl chloroacetate is added, and the mixture is maintained at a temperature between 100 DEG  and 130 DEG C. for about 50 minutes.  Decyl phthalyl decyl glycolate is isolated from the reactionmixture by the usual methods.  Examples 2, 3 and 4 relate to the preparation of decyl phthalyl 2-ethylhexyl glycolate, 2-ethylhexyl phthalyl 2-ethylhexyl glycolate, and benzyl phthalyl decyl glycolate, respectively.  In Example 6, a mixture of phthalic anhydride, tridecyl alcohol (prepared by "oxo" synthesis) and tridecyl chloroacetate is heated to 100 DEG C., and triethylamine is added over a period of 40 minutes.  The reaction mixture is worked up to give tridecyl phthalyl tridecyl glycolate.  Example 7 describes the preparation of hexyl phthalyl hexyl glycolate.  These esters are suitable plasticisers for polyvinyl chloride and copolymers of vinyl chloride (Group IV(a)).  The process can also be used for the production of phthalyl glycolate esters in which R and R1 are alkyl groups having not more than four carbon atoms.
