Title: Esters of dithiocarbamic acids
Inventor: D AMICO JOHN JOSEPH
IPC: C07D295/21
Filed: 1954-09-15
Abstract: The invention comprises compositions of esters of dithiocarbamic acid, the amino group being unsubstituted or substituted by one or two alkyl, cycloalkyl, alkenyl, hydroxyalkyl or cyanoalkyl groups of not more than 8 carbon atoms, or bisdithiocarbamic esters with substituents forming a morpholinyl, piperidyl, or pyrrolidyl ring, or (in bis-compounds) a piperazine ring which may be alkylated on the 2- and 5-carbon atoms, the ester group in all cases being a haloalkenyl or haloalkadienyl group; and the dithiocarbamic esters of formula <FORM:0769222/IV(b)/1> in which R1 is hydrogen or one of the groups specified above, R2 is alkyl of 3 to 8 C and R3 is haloalkenyl or haloalkadienyl.  The method of preparing the esters is by the reaction between a dithiocarbamic salt corresponding to the above formul  and a dihaloalkene or dihaloalkadiene, only one halogen being removed.  In examples the 3-chloro-2-butenyl-, 2-chloroallyl-, and 3-chloroallyl - N:N - dimethyldithiocarbamate, 3 - chloro - 2 - butenyldithiocarbamate; 2-chloroallyl-, 3 - chloro - 2 - butenyl -, and 3-chloroallyl - N:N - diethyldithiocarbamate, 3 - chloro - 2 - butenyl - 4 - morpholinecarbodithioate, and similar 2-chloroallyl- and 3-chloroallyl-derivatives, several chloroalkenyl-N:N-diallyl dithiocarbamates, bis-(21-chloroallyl)-2:5 - dimethyl - 1:4 - piperazine - carbodithioate and a table of similar compounds, are prepared by the action of the alkenyl dichlorides on the corresponding sodium or ammonium dithiocarbamic derivatives. Compounds in which the carbamic N is substituted by OH-alkyl and CN-alkyl are included.  The products may be employed for weed-killers as sprays, emulsions, and dry compositions, and applied solid to earth and water (see Group VI).ALSO:Herbicidal compositions contain dithiocarbamic esters of the formul  <FORM:0769222/VI/1> and <FORM:0769222/VI/2> in which R1 and R2 are hydrogen, alkyl cycloalkyl, alkenyl, hydroxy alkyl or cyanoalkyl, or R1, R2 and the N form a morpholinyl, piperidyl or pyrollidyl group, R3 is haloalkenyl or haloalkadienyl, R4 is hydrogen or alkyl, (see Group IV(b)), and dispersing agents or carriers.  Carriers referred to include talc, clay, pyrophyllite and silica, and as solvents for dispersions acetone, chloroform, alcohol, benzene and heptane and other organic liquids.  A number of dispersing agents are mentioned.

Abstract: 646,121. Transformers; protective arrangements. MIRANDA, F. J., and FERGUSON PAILIN, Ltd. Oct. 14, 1948, No. 26770. [Classes 38 (ii) and 38 (iv)] A current transformer having a U-shaped primary winding is protected against surge by the connection of a non-linear resistance between the primary winding terminals and one or more other non-linear resistances between one of these terminals and another conducting point on the winding or on a sheath or other metal part of the transformer structure. The primary winding connected between lines 3 and 4 comprises two turns 8, 9 connected in series by a link 10, and is surrounded by a conducting sheath 11 connected at 18 to line 3. Non-linear resistances 16, 17, 19, which may be of the material sold under the Registered Trade Mark " Metrosil " are connected between line 4 and line 3, link 10 and sheath 11 respectively. Upon occurrence of a surge the voltage wave passes through all the non-linear resistances to reduce voltages between different parts of the transformer and consequent risk of breakdown. The transformer casing comprises a central insulating part with metal enclosures, e.g. 2, at each end.

Title: Improvements relating to the starting of internal combustion engines
IPC: F02N5/04
Filed: 1937-10-07
Abstract: 495,346. Airscrew driving-gear. DAIMLER-BENZ AKT.-GES., and STOECKICHT, W. Oct. 7, 1937, No. 27263. Convention date, Oct. 8, 1936. [Class 4] [Also in Group XXVII] For starting an aircraft engine driving an airscrew which is initially declutched from the engine, gearing operative during starting only is interposed between the engine and the airscrew; this gearing is normally disengaged from the engine and can be driven by the starter and then operatively engaged with the engine to enable the energy stored in the airscrew to be transmitted to the engine to effect starting- As shown in Fig. 1, the engine shaft 1 is coaxial with the shaft 2 of an airscrew. Aplanetwheel 8 carried by a disc 4 on the shaft 2 meshes with a stationary toothed ring 33 and with teeth 11 on a bell-shaped member 9 freely rotatable on the engine shaft 1. A planet wheel 7 carried by a disc 3 on the engine shaft meshes with internal teeth 10 on the member 9 and with a pinion 12 integral with a braking drum 13 freely rotatable on the shaft 1. An electric starter 32 initially drives the member 9 and the airscrew shaft 2 through an automatic clutch 31 and gearing 28, 27, the pinion 12 rotating idly around the engine shaft. The drum 13 is then gradually arrested by a braking band 14 applied by a piston in a cylinder 19 to which fluid is supplied from a pump 29, and the momentum of the airscrew and other rotating parts is transmitted to the engine through the teeth 10 and planet wheels 7. When the engine starts, it drives the airscrew through the planet wheels 7, 8 and the member 9, so long as the brake band 14 is still in operation. On releasing the fluid pressure in the cylinder 19 by means of a hand-actuated valve 23, the brake band 14 is released and an automatic clutch 35, 34 couples the member 9 directly to the engine shaft, so that the airscrew is driven through one stage (8) of planetary gearing. The clutch member 35, Fig. 4, is connected by axial splines 37 to the member 9 and by interengaging inclined teeth 38 to a bushing 40 frictionally held by a spring 41 in a recess 42 in the engine shaft 1. In a modification, an additional stage of reduction is obtained between the member 9 and the drum 13 by making the teeth 10 engage a smaller wheel coaxial and integral with the planet wheel 7, which may be enclosed within the rim of the drum 13. The pump 29 may employ lubricating oil or cooling water, and the band brake 14 may be replaced by a liquid, pneumatic, electric, or other brake or clutch device.

[Also in Division A4] A non-slip surface is produced by applying to a metal element to be surfaced a primary vitreous enamel coating which is fusible when fired to a temperature within a given range, applying a secondary layer of refractory material to the enamel coating which secondary layer will not vitrify when fired to the same temperature and firing the coatings at this temperature to combine the layers into a composite coating layer. The secondary layer may consist of a mixture of a refractory material and a non-vitrifiable material to provide a high friction surface when fired to the same temperature, e.g. a slurry of 276 parts by volume consisting of 100 parts silica flour, 3 parts clay, 35 parts water and 138 vitreous enamel. In an example a metal bath is sprayed with a vitreous enamel, allowed to dry and then the above slurry sprayed on through a screen or template after which the resultant coatings are fired.
