Title: Process for the preparation of alkylborines
IPC: C07F5/02
Filed: 1960-08-23
Abstract: An alkylborine is made by reacting an alkyl aluminium alkoxide at an elevated temperature with a boron compound BX3 wherein X is a halide radical.  Suitable temperatures vary from 100 DEG C. to 300 DEG C. but it is preferred to operate at 200 DEG C. to 250 DEG C., the resulting trialkyl borine being recovered by distillation.  If desired, the reaction may be effected under superatmospheric pressure.  Suitable alkyl aluminium alkoxides are specified, the term alkyl including cycloalkyl, dialkylaluminium alkoxides being preferred.  Boron trifluoride is preferred for reasons of economy but boron trichloride or boron tribromide may also be used.  An example describes the production of triethylborine from diethylaluminium n-butoxide and boron trifluoride in diethyl ether.

Title: Hydraulic transmissions
IPC: F16H39/40
Filed: 1973-06-20
Abstract: 1391753 Hydrostatic transmissions BORG WARNER CORP 20 June 1973 [13 July 1972] 29340/73 Heading F2D In a hydrostatic transmission comprising a pump 70 and two, series connected, motors 13a and 13b, the pressure drops across the motors are maintained equal, or at a constant ratio by a valve 72 having within it two pistons, 83, 84, the former being acted upon by the pump 70 output pressure via a shuttle valve 17 and the latter, of greater area 94 than the former, being acted upon by the pressure in the connection between the motors. If the pump 70 output pressure (in lines 112, 113, 114 and 115), is too great relative to the pressure in the line between the motors 13a, 13b the force on piston 83 through the pressure in chamber 126 moves the pistons to the right to cause fluid to pass via line 39, valve 17, line 123 port 85 of valve 72, and port 86 (the condition shown), to the connection between the motors, thus by-passing the motor 13a and returning the pressure drops to their desired ratio. Similarly too great a pressure between the motors relative to the pump 70 output pressure moves the pistons to the left to allow fluid to by-pass motor 13b and pass to the low pressure line 121 via a check valve 74. For equal pressure drops across the two motors 13a, 13b the piston 84 must have about twice the area of piston 83. Throttle valves may be included in the lines to the valve 82 to restrict the flow therethrough and provide a limited slip differential action. In the embodiment shown, the pump 70 is variable displacement and reversible and is in closed circuit with motors 13a, 13b, a feed pump 75 protected by a relief valve 77 is provided, supplying the low pressure line via a check valve 74 and a valve 71 is provided which can connect the motors 13a, 13b in parallel if the spool therein is moved to the right. A simplified embodiment (Fig. 1, not shown), has a constant displacement pump, a reversing valve providing change of direction of flow, no feed pump or series-parallel valve and an open circuit arrangement. The pump here is protected by a relief valve returning fluid to the sump. In each embodiment the shuttle valve 17 ensures that the operation of the transmission is not affected by the direction of flow from the pump, and that the motors have their pressure drops kept at the desired ratio even during overrun. The valve 72 may be spring-biased by springs 89 or 90.

Title: Improvements in the manufacture of hydrogen or gases containing hydrogen from methane, and similar hydro-carbons or gases containing these hydrocarbons
IPC: C01B3/46
Filed: 1929-10-03
Abstract: Hydrogen or gas mixtures containing hydrogen are obtained by the alternate passage of hydrocarbon gas, with or without the addition of steam, and air through a bed of highly heated coke or refractory material, the air being supplied at different levels within the bed or in different amounts at different levels.  Air is passed into a heat regenerator 7, through a valve 14, through regulating valves 16 on tuyeres 13 and into a coke bed 2 where it burns the carbon deposited during the previous run and some coke. The "blow" gases thus formed enter a combustion chamber 12 <PICT:0340050/III/1> where they are burnt by preheated secondary air entering through pipe 10. The valves 11, 3, 6 and 14 are then closed and the valves 4, 5, 9 and 15 opened, 9 to a small extent.  Hydrocarbon gas, with or without steam passes through the heated regenerator 8, is decomposed by the hot coke 2 and passes out through valves 15 and 9, the portion passing through 9 preheating the fresh coke and that passing through 15 heating the regenerator 7 and escaping through valve 5.  The regenerator 7 should be purged before and after each blow with steam or combustion gases.  A heat exchanger may be provided instead of a regenerator, two plants being connected to the same heat exchanger. Specification 328,642, [Class 55 (i), Coking &c.], is referred to.
