Title: Hard emulsifiable and odourless synthetic waxes and a process for their production
Inventor: ZEITLER GERHARD
IPC: C08F8/50
Filed: 1963-05-15
Abstract: In a process for the production of hard, emulsifiable, odourless, synthetic waxes, a polyolefine having a molecular weight between 1,800 and 10,000 (obtained by thermal degradation of a polyolefine having a molecular weight of more than 10,000) is reacted, while excluding atmospheric oxygen and at 180 DEG  to 300 DEG  C., with 0.5 to 5% by weight, based on the amount of polyolefine, of an unsaturated aliphatic carboxylic acid or anhydride.  In a modification of the process, a polyolefine having a molecular weight of more than 10,000 is thermally degraded, at 200 DEG  to 500 DEG C., into a product having a molecular weight between 1,800 and 10,000 and at the same time is reacted with an unsaturated aliphatic carboxylic acid or anhydride under, otherwise, the same conditions as specified above.  There may be coemployed, with said unsaturated acid or anhydride, 0.2 to 1% by weight, based on the amount of polyolefine, of a monoester or diester, where existent, of said unsaturated acid, e.g. diethyl maleate.  The polyolefines may be homopolymers or copolymers, and also copolymers of mono-olefines with carbon monoxide; isotactic polypropylene and high and low pressure polyethylene are exemplified. The unsaturated carboxylic compounds specified are maleic acid, fumaric acid, aconitic acid, citraconic acid, acrylic acid and crotonic acid, and their anhydrides, where existent.  The process of the invention may be carried out under nitrogen and at atmospheric or raised pressure.  The carboxylic reactant(s) may be added in small portions during the course of the reaction.  The polyolefine degradation can be carried out batchwise or continuously.  Specification 885,969 is referred to.

Title: Improvements in shaft furnaces
IPC: F27B1/02
Filed: 1927-07-21
Abstract: 291,258. Simon, G. July 21, 1927. Cupola furnaces; reverberatory furnaces. - A cupola furnace 1 for melting pig iron, steel, scrap metal, and the like is heated partly by the combustion of coke mixed with the charge and partly by hot gases from burners 12 arranged in the top and sides of a chamber 7, which is in communication with the shaft 1 through a slag-separating chamber 4 and conduit 3. The chamber 7 is formed with openings 15 for the supply of alloying or other material and is connected by channels 6, 5 respectively, to the upper and lower ends of the separator 4, which latter also communicates through a damper-controlled opening 8 with a recuperator 9 serving to supply heated air to the burners 12. In starting up, after the cupola 1 has been charged, the dampers 10, 11 are closed and the burners 12 lit, the gases passing through passages 5, 4, 3 into the shaft 1 to ignite the coke therein. Blast is then supplied through the tuyeres 2 and, as soon as molten metal appears in the channel 5, the dampers 10, 11 are opened, thus permitting the burner gases to pass through the passage 6 and thence partly to the shaft 1 and partly to the recuperator 9. The slag which. floats on the metal in the chamber 4 is drawn off through a tap-hole 14. The burners 12 are supplied, from an external source, with liquid, gaseous, or pulverulent fuel, and the amount of air supplied thereto from the recuperator 9 may be varied to produce an oxidizing or reducing flame. A modification is described in which the chamber 4 is arranged to deliver molten metal to two burner chambers 7 arranged one on each side thereof.

Title: Improvements in or relating to machines for folding margins of sheet material
IPC: A43D8/40
Filed: 1934-07-02
Abstract: 440,805. Stopping and starting mechanisms. BRITISH UNITED SHOE MACHINERY CO., Ltd., Belgrave Road, Leicester.- (United Shoe Machinery Corporation; Paterson, New Jersey, U.S.A.) July 2, 1934, No. 19428. [Class 80 (ii)] [See also Group VIII] The shaft 121 of a machine for folding the margins of sheet material, e.g. leather, is arranged to be stopped always in one position. As shown, the shaft 121 is driven from a pulley 313 through a series of rollers 303 and a cam sleeve 301<1> secured to the shaft. The roller cage 305 has a limited rotation relatively to the cam 301<1> and is moved in one direction to engage the clutch by a spring 315 and arrested in one position only to disengage the clutch by a projection 319 and a stop 317. The stop 317 is pivoted at 327 and connected by a rod 339 to a pedal controlling a friction clutch in the main drive. When this friction clutch is disengaged to stop the machine, a spring tends to pull the stop 317 into the path of the projection 319 but is prevented by a pin 353 until the shaft 121 has slowed down to some predetermined extent. In the example shown, governor weights 375 pivoted at 379 in the pulley 313 rotate a disc 369 fitted with cams 367 which move a collar 351 axially under the pin 353 when the speed is above the desired amount. A pivoted pawl 321 is allowed to engage teeth on the sleeve 301<1> and is withdrawn therefrom at the same time as the stop 317 is put into and out of action. Specification 5436 /07, [Class 80], is referred to.

Title: Improvements in or relating to insecticidal compositions
Inventor: EATON JOHN KENNETH
IPC: A01N41/10
Filed: 1951-08-20
Abstract: An insecticidal composition in concentrated form which may be readily diluted with water to give stable dilute fine aqueous suspension for use in combating the red spider mite comprises at least 10 per cent by weight of a diphenyl sulphone, which may carry one or more halogen and/or nitro substituents, in the form of particles in stable suspension in a hydrocarbon oil and an emulsifier, 4-chlorodiphenyl sulphone, 4:41-dichlorodiphenyl sulphone, the corresponding nitro compounds, and 4-chloro- 41- nitro-diphenyl sulphone may be employed. The hydrocarbon oils in which the diphenyl sulphones are dispersed are substantially non-solvents for the sulphones and should be of low volatility.  Hydrocarbon oils of moderate viscosity such as spindle oils and similar light lubricating oil distillates are preferably employed.  Any wetting or emulsifying agents may be employed, but emulsifiers of the non-ionogenic type, such as the condensation products of ethylene oxide with phenols and with carboxylic acids and the partial esters of polyvalent alcohols, are preferred.  The alkyl phenol polyethylene glycol ether Triton X-100 (R.T.M.), is specified. If desired non-ionogenic emulsifiers may be used in conjunction with ionogenic emulsifiers, e.g. oil soluble mineral oil sulphonates. Concentrated preparations suitable for marketing advantageously contain from 20 to 50 parts by weight of sulphone and from 20 to 40 parts of hydrocarbon oil and may be diluted for application at the rate of about 6 pounds of preparation to 100 gallons of water. Concentrates containing high proportions of sulphones are thick pastes, and a small quantity of water, in general 20 to 30 per cent by weight may advantageously be incorporated in the concentrate. Other insecticides and fungicides may be incorporated in the composition, for example bis (p-chlorophenyl) trichlorethane, a-benzene hexachloride or commercial mixtures thereof, lead arsenate, copper oxychloride and products sold under the names Chlordane, Toxaphene, Aldrin and Dieldrin.

Abstract: 440,734. Converting. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. July 5, 1934, No. 19816. Convention date, July 5, 1933. [Class 38 (ii)] [See also Group XXXVII] A motor is connected to an alternating- current source through two reversely-connected groups of grid-controlled discharge devices 41, 411, arranged for inverter and rectifier operation under the control of a single lever 11 whereby the motor is arranged for regenerative and motoring operation in either direction, a supplementary grid potential being applied, under the control of the lever 11, to prevent discharge in one or other of the groups of discharge devices. The lever 11 is geared to grid regulators 43<1>, 43<11>, in such a way that, upon movement of the lever from the central position shown, one of the groups of discharge devices is adjusted for rectifier operation, and the other, operated to a smaller extent, for inverter operation. Supplementary grid potentials 42<1>, 42<11>, which prevent discharge in corresponding groups of discharge devices, are rendered effective or ineffective under the control of switch contacts 44<1>, 44<11>, on a switch lever frictionally coupled with the lever 11. Thus, with the lever 11 operated to a position in which the motor is connected through one group of discharge devices operating as a rectifier, the other group of discharge devices, adjusted for inverter operation, is prevented from discharging by its supplementary grid potential. Upon operating the lever 11 from such a position in a reverse direction, the group of discharge devices adjusted for inverter operation becomes effective, and the other group is rendered ineffective. Specification 405,638 is referred to.
