Patent GB-434612-A (GB)
Title: Improvements in and relating to power transmitting mechanisms in reciprocating engines
IPC: F16H43/00
Filed: 1934-04-04
Abstract: 434,612. Driving - gear. LOGANNEWVILLE MOTORS, Inc., 622, Washington Street, Cape May, New Jersey, U.S.A. April 4, 1934, No. 10176. Convention date, April 20, 1933. [Class 7 (ii)] [See also Group XXVI] Pistons 42 working in expansion or combustion chambers 12 are rigidly connected to pistons 44 working in cylinders 21 immersed in liquid in a tank 10. Air or other elastic medium occupies the space above the liquid in the tank. Fluid displaced by the piston 44 escapes through a valve 23, and returns or passes to a companion cylinder, through valved piping 35, 36, thus effecting the return stroke of the combined pistons, and through the engagement of ratchet and pawl, or of a rack 47 with a toothed quadrant 48, driving the shaft 46. A butterfly-valve in the housing 70 controls the admission of fluid to the cylinders 21 and is operated by linkwork from a cam on the shaft 77, while supplementary control may be effected by a manually or automaticallyoperated valve 78. In a modification, a spherical valve may replace the disc-valve 23, and the air &c. in the tank 10 may be separated from the fluid by confinement above a plunger in a cylinder. Instead of the rack 47 being offset from the axis of the cylinders, the shaft 46 may be placed to one side. The teeth of the quadrants 48 extend a tooth further than the driving effort of the rack is effective, thereby overlapping similar quadrants along the shaft. In the case of an internal-combustion engine air or mixture is compressed in cylinders 41 and transferred to and ignited in the cylinders 12. One pump cylinder may serve two explosion cylinders, and the spaces below the piston 42 and above the piston 44 may be utilized for compression. For cushioning purposes the piston 44 is made in two parts nesting conically one within the other and urged apart by a spring. Towards the upper end of its stroke the upper cone engages a stop. Oil leaking past the lower piston member collects in the recess between the cones and returns below the piston through non-return valves when the latter are opened as the two cones are pressed together at the upper end of their travel.

Title: Process and apparatus for the production of dialkyl aluminium hydrides and aluminium trialkyls
IPC: C07F5/06
Filed: 1956-04-03
Abstract: <PICT:0836792/IV (b)/1> Aluminium is heated with an aluminium tri alkyl and hydrogen at a pressure higher than 20 atmospheres to produce a dialkyl aluminium hydride.  The aluminium is preferably in finely-divided form, such as atomized aluminium formed by spraying molten aluminium by means of an inert gas into liquid aluminium trialkyl in an inert solvent such as hexane or benzene. The aluminium may also be activated by mechanical comminution or by corrosion with a dialkyl aluminium monohalide.  The reaction product may be further treated with an olefin to give an aluminium trialkyl, either as a separate step or by forcing the olefin under pressure into the reactor in which the dialkyl aluminium hydride is formed.  The process may be conducted in the apparatus shown in the drawing. Molten aluminium is sprayed from a supply vessel 1 into a chamber 2 containing a, say, 5% solution of aluminium triethyl.  The suspension is allowed to settle in vessel 5, the solvent being returned to chamber 2 via line 4 and the thick suspension being pumped to reaction tower I via pump 7 and line 8. Hydrogen is supplied via line 9 and any extra aluminium triethyl required via line 11.  The reaction product passes to a separator 13, hydrogen being removed at 14 and recycled, and diethyl aluminium hydride passing via line 15 to reactor II where it is reacted with ethylene introduced via line 16. The product mixture is separated in distillation column 18, ethylene being recycled via line 19, solvent returned to the atomization chamber 2 via line 3, and the residual aluminium triethyl being extracted via line 20, a measured proportion being conveyed to tower I via pipe 21.  Specification 770,707 is referred to.

Title: Improvements relating to the reduction of the far-end crosstalk in trunk communication cables
IPC: H01B11/04
Filed: 1934-04-10
Abstract: 427,365. Preventing inductive disturbances. SIEMENS & HALSKE AKT.- GES., Siemensstadt, Berlin. April 10, 1934, No. 10803. Convention date, April 10, 1933. [Class 40 (iv)] [See also Group XXXVI] Far-end cross-talk is reduced by making the ratio of the capacitative to the magnetic couplings equal or substantially equal to the ratio of capacity to inductance of the pairs or quads. Either of the quantities in question may be adjusted to bring about desired equality of ratio. The couplings may be varied by additional condensers or magnetic coupling elements as described in Specifications 147,013 and 304,229, [both in Class 40 (iv)], respectively. The actual capacity or inductance of the lines may be adjusted or varied in the construction of the cable or by choice of circuits in the cable. If the distance between a line and a surrounding conductive screen or surrounding lines is made sufficiently large relatively to the distance between the cores of a line, the line capacity is independent of the presence of the screen, and the ratio of capacity to inductance can be given a desired value by varying the distance between the cores. Another method consists in enclosing each core in a closed or meshed screen so that the inductance can be varied independently of the capacity by varying the distance between the cores, the capacity being determined by the thickness of the insulation between a core and its screen. Crossing between cores may also be utilized for this purpose and also to reduce near-end cross-talk. In the cable shown, eight cores individually screened are stranded around a central portion 10 of insulation containing air spaces or comprising a bundle of cores. The eight cores are surrounded by further insulation 12 or a layer of cores, and an outside sheath 13. Different inductance values can be obtained, e.g. by selecting cores 1 and 2 or 1 and 5 for a pair. When diametrically opposite cores are all used as pairs, couplings may be varied by crossings according to a definite plan, and when cores 1, 5, 3, 7 and 2, 6, 4, 8 are used as quads, the two quads as a whole may be crossed at definite intervals or other interchanges in the relative position of the cores may be effected. A number of groups as shown may be stranded together to form a larger cable. The couplings may also be varied by introducing short lengths of magnetic or non-magnetic screens of different thicknesses or materials or by using different kinds of cable, e.g. continuously or lump loaded.
