Abstract: 211,494. Naugatuck Chemical Co., (Assignees of Cadwell, S. M., and Smith, O. H.). July 13, 1922, [Convention date]. Addition to 174,915. Vulcanizing-compositions.-In the process for accelerated vulcanization which consists in incorporating with india-rubber &c., (1) a metal in combination, (2) an amine, (3) a material providing sulphur, and (4) a material comprising carbon disulphide or oxysulphide, two or three of the materials are first mixed with the rubber and the remaining ingredient or ingredients is or are introduced by permeation from a medium other than rubber without changing the shape of the rubber mass. The combined metal may be zinc, mercury, lead, cadmium, copper, arsenic, or manganese. Sulphur may be used in the free state or as a compound from which it is transferred to rubber under vulcanizing conditions. Suitable amines and derivatives of carbon disulphide, &c., are those mentioned in Specification 177,493. A single compound may furnish two of the fourclasses of ingredients, e.g. oxynormal butylthiocarbonic acid disulphide (carbon disulphide and sulphur) and zinc butyl xanthogenate (zinc and carbon disulphide). The Specification contains several examples, of which the following are typical, (1) a thin sheet of rubber containing zinc oxide and sulphur is painted with solutions of dibenzylamine and carbon disulphide. (2) A thin film of rubber containing zinc butyl xanthogenate and dibenzylamine is treated with a solution of sulphur. Specification 200,789 also is referred to.

Title: Oxidation of benzene homologues
Inventor: OWEN EDMUND CECIL
IPC: C07C51/275
Filed: 1951-02-21
Abstract: Paracymene is oxidized to terephthalic acid by use of nitric acid by a process characterized in that the nitric acid is injected into the reaction vessel continuously over a relatively extended period of time and at a variable rate by use of a pump of variable delivery rate, the rate of injection being adjusted so that the volume and composition of the gas taken off through the release valve measured at atmospheric pressure are approximately uniform, the composition being determined by analysis.  In an example aqueous nitric acid of 30 per cent strength is injected into a reaction vessel at 190 DEG C. and at a pressure of 200 lb./sq. in.  The nitric oxide content of the issuing gases may be measured by observations of the paramagnetic susceptibility thereof and, if desired, the instrument used to measure said paramagnetic susceptibility may be employed to operate an automatic control of the nitric acid feed.

Title: Improvements in protective arrangements for electric circuits
IPC: H01H71/42
Filed: 1924-02-20
Abstract: 223,477. British Thomson-Houston Co., Ltd., (General Electric Co.). Feb. 20, 1924. Protective arrangements; induction relays.- Circuits are protected against abnormal conditions by a relay with two separately and independently movable co-operating contacts, one controlled by the voltage and movable an amount dependent on the decrease of voltage below a predetermined value, and the other controlled by the current and movable at a speed dependent on the increase of current above a predetermined value, whereby the relay closes in a time-interval dependent on the current and voltage of the protected circuit. The relay serves to control circuit-breaking or indicating apparatus with a discriminating time action dependent upon the degree and location of the fault. As shown in the Figure employing induction-type actuating devices, the disc 7 is caused to rotate, in the direction indicated, by a magnet 10 energized by coils 12, 13 supplied from the voltage transformer 14. The disc is controlled by the permanent magnet 16, and adjustable stops 23, 24 co-operating with the projection 22 limit the movement. The disc is connected with a spindle 9 controlled by the spring 17 and gearing with a rectilinearly-moving rod carrying a, contact 4 which co-operates with the companion contact 5 on another induction actuating device 8 with current excitation, shaded poles 31 and a progressively notched induction disc to give constant action. The contact 4, under the action of the spring 17 constantly tends to approach the contact 5 but is withheld therefrom until the voltage at 14 falls below a certain value. An increase of current beyond a certain value moves the contact 5, against the action of the spring 35 and at a rate dependent on the current, towards the contact 4. The contact 5 is driven through a. spring 43 to allow for overdriving.

Title: Improvements in or relating to propeller pencil holders
IPC: B43K21/08
Filed: 1921-02-07
Abstract: 179,631. Hudson, G. R. Feb. 7, 1921. Pencil-holders.-In a pencil-holder of the type in which a key b, Fig. 1, on the lead-carrier a passes through a slot e in a tubular member d, in which the carrier moves, into engagement with a wire helix f wound round the tubular member, the helical member is only in frictional contact with the outer case j, so that in the event of overwinding, the helix slips in the casing. The ends of the wire f are bent round at g, h, to lie longitudinally of the holder to form a stop for the key b when the carrier is at either end of its movement. The tubular member d is attached at the front end to the point section o, and at the rear end is expanded over a washer q placed against a flange k in the casing. The rear end of the casing is closed by a screw cap n to form a receptacle m for spare leads. When the casing is turned relatively to the point section, the helix is carried round to move the carrier. In order to take up wear between the parts j, o, the back part of the flange k may be cut away and a small compression spring inserted between the flange and the washer g. In the modification shown in Fig. 5, the inside of the casing j is provided with a brass lining r flared at the front end to engage a groove t in the casing. Near the rear end of the lining, and corresponding in position to the flange k, is secured a brass bush v, through a hole in which the tube d passes, a compression spring p being provided between the bush v and washer q to compensate for wear.

Abstract: The invention comprises compounds of the formula <FORM:1032052/C3/1> where X and Y may each be a lower alkyl, cycloalkyl of 5-11 C atoms, aryl of 6-13 C atoms, pyridyl, or quinolyl group and RA, RB, RC and RD may each be an alkyl, cycloalkyl of 5-11 C atoms, aryl of 6-13 C atoms aralkyl of 7-11 C atoms, alkoxyalkyl of 2-9 C atoms, phenoxy phenyl of 12-18 C atoms, pyridyl or quinolyl group.  They are prepared by three main processes: (1) (a) by heating a hydrosilane of type RARBXiH2 with an amine XNH2, in an inert solvent, or molten under an inert atmosphere, or (b) by heating the hydrosilane with a bis-(secondary amino) silane, or (c) by heating a secondary aminohydrosilane. A metallic e.g. copper, or basic e.g. NaH, NaNH2 catalyst is required.  (2) by heating (a) a bis-(secondary or tertiary amino) silane with the amine XNH2, or (b) a higher cyclosilazane, e.g. (RARBSiNH)3 or 4 with XNH2; (3) by heating a bis - (secondary amino) silane RARBSi(NXH)2 alone or in a high-boiling inert solvent.  All these processes are carried out under an inert atmosphere, at a temperature between 150 DEG  C. and the decomposition point of any amine present.  The product is separated by precipitation by an alkane solvent, e.g. peptane, or by extracting the cooled, solidified reaction mixture with a suitable solvent, e.g. benzene.  The examples describe the preparation of cyclodisilazanes by the above methods, wherein the Si-bound groups are phenyl and methyl, and the N-bound groups are phenyl, p-tolyl, 3,5-xylyl, methyl, ethyl, cyclohexyl, 2-pyridyl and 3-quinolyl. Temperatures of 260 DEG -335 DEG  C. are typical, and the solvent, if one is used, may be phenyl ether or o-diphenyl-benzene. The compounds are used as curing agents for epoxy resins, possibly in conjunction with (NH4)2SO4.
