Title: Organosilicon compounds and processes for their production
IPC: C07F7/18
Filed: 1960-02-24
Abstract: The invention comprises aminomethylphenylsilicon compounds containing units of the formula: <FORM:0874150/IV (a)/1> where Z is hydrogen or an alkyl, aryl or aralkyl radical, R is an alkyl, aryl, aralkyl, alkoxy or aryloxy radical, a is 1 or 2, b is 0, 1 or 2, and the balance of the silicon valencies are satisfied with OR1 radicals in which R1 is alkyl, aryl or aralkyl, or with oxygen atoms attached to silicon atoms to form polysiloxanes.  They are prepared by hydrogenating the corresponding cyanophenyl silicon compound, and if desired, converting the primary amine to a secondary or tertiary amine. The hydrogenation is preferably conducted under pressure and at temperatures of 80 DEG -140 DEG C. Catalysts may be used, e.g., platinum or palladium, alone or supported on gamma-alumina or charcoal, nickel, cobalt and bis (cyclopentadienyl) nickel.  Solvents such as alcohols and hydrocarbons may be present.  The conversion of the primary amine to the secondary or tertiary may be effected by reacting with the hydrocarbon halide or sulphate.  The siloxanes may also be prepared by hydrolysis of the silanes of the invention, or, if desired, by cohydrolysis with, for example, Me2Si(OEt)2.  The examples describe the preparation of (1) and (2) p- and m-aminomethylphenyltriethoxy silane; (3) a solid siloxane having the formula m-H2NCH2C6H4 SiO1,5; (6) N,N-dimethyl-p-aminomethyl-phenyltriethoxysilane.  The use of compounds (1) and (2) as corrosion inhibitors is also described (Examples 4 and 5) and compared with the silanes H2NC6H4Si(OC2H5)3 and H2NC6H4 CH2CH2SiCH3(OC2H5)2.  The Specification also lists other silanes and siloxanes of the invention.  Uses: corrosion inhibitors, lubricating oils, sequestering agents, coatings for metals.  The cyanophenylhydrocarbonoxysilanes used as starting materials are prepared by reacting alkali metal cyanides with bromophenylhydrocarbonoxysilanes in a highly polar organic liquid, e.g. diethylformamide, in the presence of cuprous cyanide and copper, at 25 DEG -250 DEG C.  Hydrolysis produces the corresponding siloxane starting materials.

Title: Improvements in or relating to hydraulic control systems especially for tractor-mounted agricultural implements
IPC: F15B21/00
Filed: 1947-03-07
Abstract: 632,214. Agricultural implements. FERGUSON HOLDINGS, Ltd., H., FERGUSON, H. G., SANDS, W. J., and CHAMBERS, J. March 7, 1947, No. 6455. [Class 6(i)] [Also in Group XXIX] Relates to tractors having a hydraulic system of the type wherein a continuouslydriven pump 20 feeds oil to a hydraulic ram 6 the piston 7 of which is connected to lifting arms for raising and lowering implements mounted on the tractor and wherein the oil is supplied to or ejected from the ram as the result of the movement of a valve 21, the position of which is affected by the depth of working of the tools. According to the invention, the system includes a reservoir 26 for fluid under pressure which is supplied by the pump, and the fluid inlet 23 on the suction side of the pump is controlled by a valve movable in accordance with the pressure attained in the reservoir. The system is shown applied to a tractor which is connected to the implement by upper and lower hitch links. The implement-controlled valve includes a double plunger 21, 39 slidable in a bushing 37 having ports 35, 40 through which fluid passes to and from the ram. The plunger is connected by pivoted links to a double lever, of the type described in Specification 550,142, whereby the valve may be operated manually, or automatically by the movement of the lifting links, to regulate the depth of cut of the tools. The pump includes a cam-operated piston 20 and is fed with oil from a sump through an inlet 23 controlled by a piston valve 24 working against a spring 25. On the delivery side 27, the pump feeds the implement-controlled valve 21 through a conduit 22 and the reservoir 26 through a conduit 22a. The reservoir 26 includes an airfilled chamber 54 separated from the oil chamber 53 by a diaphragm 52. A conduit 48 connects the reservoir with a passage 44 within which is located a plunger 24a connected to the piston valve 24. When the reservoir pressure exceeds a predetermined quantity the valve cuts off the intake of oil to the pump. Since the reservoir provides an immediately-available supply of oil for operating the ram, the lag in the system is much reduced. Specifications 470,069 and 470,087 also are referred to.

Patent GB-478293-A (GB)
Title: Improvements in or relating to clutch devices
IPC: H01C10/02
Filed: 1937-03-06
Abstract: 478,293. Operating clutches. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 6, 1937, No. 6697. Convention date, April 22, 1936. [Class 80 (ii)] A pawl-and-ratchet clutch is controlled by projections 33, 34 on one arm 32 of a spring-loaded lever, the other arm of which carries the armature 30 of an electromagnet 25 and which is pivoted on one arm 29 of a spring-loaded lever which is pivoted on a fixed pin 28 and the other arm of which carries the armature 27 of an electromagnet 26. The driven clutch member 10, which is journalled on the driving shaft 2 and which may form part of a cornmutator device, has fixed therein a pin 18 on which is pivoted an arcuate pawl 19 and which extends through a slot 17 in a plate 14 mounted loosely on the member 10. The free end of the pawl carries a pin 20 extending through the plate 14, and a tension spring 22 arranged in an arcuate recess in the member 10 urges the pawl towards engagement with a ratchet wheel 21 secured to the shaft 2. The plate 14 has a number of projections 16, four being shown. Normally, with the magnets 25 and 26 de-energized, the parts occupy the position shown in Fig. 1, one of the projections 16 being in engagement with the projection 33 and the pawl being disengaged. On energizing the magnet 26, the arm 32 is swung clear of the projections 16, and the pawl engages the ratchet wheel under the action of the spring 22, the plate 14 turning forwardly on the member 10. On de-energizing the magnet 26, the projection 33 returns into the path of the projections 16 and is engaged by the first of the latter. The plate 14 is thus stopped and, as the member 10 continues to rotate, the pawl is disengaged. The member 10 continues to move forwardly, assisted by a spring-pressed arm 37 coacting with rollers 11 carried by the member 10, until one of a number of notches 13 in the member 10 is engaged by a spring-loaded detent 35 so as to prevent rebound. If the magnet 25 is energized, the arm 32 is swung only so far as the position shown in Fig. 6, in which the projection 34 remains in the path of the projections 16. The pawl thus moves towards engagement but is arrested, before actual engagement takes place, by the projection 16 abutting against the projection 34. On now de-energizing the magnet 25, the projection 16 passes between the projections 33, 34 and the clutch engages, but disengages automatically after one quarter of a revolution due to the engagement of the succeeding projection 16 with the projection 33.
