Title: Manufacture of polymers and interpolymers of ethylene
IPC: D21C11/00
Filed: 1943-06-28
Abstract: Ethylene is polymerized by subjection to elevated temperatures and pressures in the presence of oxygen or a per-compound and, if desired, a liquid medium, in a tubular converter.  Suitable per-compounds are hydrogen peroxide, persuccinic acid, lauroyl, tetralin, urea, butyryl, acetyl, acetobenzoyl and diethyl peroxides, peracetic acid, alkali metal, alkaline earth metal and ammonium persulphates, perborates and percarbonates.  The liquid medium may be water, benzene, toluene, chlorobenzene, isooctane, methanol or ethanol.  The process may be used for interpolymerizing ethylene with propylene, isobutylene, styrene, vinyl formate, acetate and isobutyrate, acrylic, methacrylic, itaconic, citraconic, crotonic, maleic and fumaric acids, their esters, acid halides, amides and anhydrides, vinyl and vinylidene chlorides, vinyl cyanide, N-vinyl amides, vinyl ethers, divinyl formal, divinyl butyral and methyl vinyl ketone.  The process is preferably carried out continuously with the liquid in turbulent flow through the converter, which may be tilted at an angle to the horizontal, so that the point of admission is at a lower level than the point of exit.  In examples, the converter is a stainless steel tube 40 feet long and of 3/16 " internal diameter.  A draw-off valve at the exit leads down to a separator from which gas and liquid are continuously withdrawn and the solid present removed hourly.  The gas is returned to the inlet with make-up ethylene through an electrically-heated draw-off valve. The process is also applicable to the production of telomers as described in Specifications 572,810, 581,899, 582,663, 583,118 and 583,181.

Title: Improvements in or relating to control systems for electric generators
IPC: H02P9/32
Filed: 1955-04-15
Abstract: 779,382. Automatic control systems for alternators. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. April 15, 1955 [April 20, 1954], No. 10897/55. Class 38 (4). In order to limit the self-excitation of an alternator under certain conditions, highimpedance shunt paths connected across output current transformers supplying the field are rendered highly conducting at a predetermined value of output current. Thus, in Fig. 1, current transformers 26, 28, 30 supplying the alternator field 18 through rectifiers 32 have respective shunt circuits 56, 58, 60 comprising back-to-back crystal diode pairs such as 66, 68. The latter permit conduction in their respective paths at a certain value of applied voltage, thereby limiting the field excitation. Further diode pairs such as 84, 86 may be connected in the shunt paths by opening of their respective shorting contacts in order to adjust the voltage at which the paths conduct. Additional excitation for output voltage regulation is provided by an A.C. exciter 190 driven by the alternator and supplying field rectifiers 234 through self-saturating reactors load windings such as 204. Reactor control windings such as 154 are series-energized from the output across a resistor 134 of a voltage reference network 102, the latter comprising non-linear circuits 114, 116 energized from a voltage transformer 106 over a frequency compensating circuit 100 and supplying rectifiers 118, 120 respectively. Series reactor feedback windings such as 168 are energized over a transformer 182 supplied in parallel with the field 18. A main exciter may be connected between transformer 182 and rectifier 32. The above system permits a linear variation of excitation with load requirement and sufficient but not excessive excitation under short circuit conditions for tripping load circuit breakers to isolate the short. In a modification, Fig. 2 (not shown), saturable reactors replace the crystal diodes. In the case of two parallelconnected generators supplying a common load, Fig. 3, excessive droop compensation is prevented by shunting the droop compensation current transformer 288 responsive to the output of generator 286 by back-to-back connected crystal diodes 292, 294. The signal applied over a resistor 290 to the voltage regulating circuit to modify the output voltage of alternator 12 is thus limited to a value at which the diodes conduct. A saturable reactor may replace the diodes in the shunt path.

Title: Improvements in and relating to the low-temperature distillation of carbonaceous materials
IPC: C10B49/00
Filed: 1945-05-01
Abstract: In a process for the recovery of hydrocarbon distillates substantially free from phenols, from solid carbonaceous materials mixed with mineral oils, there is added to the carbonaceous material or the oils a catalyst comprising a metal of the iron sub-division of the Periodic System, or tin, or oxides of such metals or mixtures of such metals and oxides in the proportion of from 0.1 to 5 per cent. of the carbonaceous material.  The mixture is then subjected to distillation at 200-650 DEG C. and the vapours evolved are recovered and condensed.  An alkaline carbonate such as Solvay soda may be incorporated in the mixture, the amount added being at least equal to the weight of catalyst added.  The catalyst should be in a finely powdered state and may be a natural mineral, such as cassiterite or haematite, or derivatives of the metals which decompose under the distillation conditions to leave the metal or its oxide may be employed.  In one example 1 per cent. of finely powdered iron oxide is added to a crude light fuel oil which is distilled at 550 DEG C. with a lignite from the South of France and in another, a catalyst comprising 1 per cent. of each of iron oxide and Solvay soda is added to a lignite and a lignite oil containing phenols and the mixture is distilled at 600 DEG C.  In the Specification as open to inspection under Sect. 91, the catalyst comprises at least one polyvalent metal, such as vanadium, molybdenum, iron, manganese, nickel, cobalt or tin or a naturally occurring mineral or derivative of at least one of the metals, such as molybdenum chlorhydrin, vanadium oxychloride, or iron carbonyl.  This subject-matter does not appear in the Specification as accepted.
