Title: Improvements relating to the removal of nitrogen compounds from hydrocarbon fractions
Inventor: LAURENCE RICHARD TRAVERS
IPC: C10G45/04
Filed: 1964-09-08
Abstract: A process for the removal of nitrogen compounds from a hydrocarbon fraction comprises contacting it at 400 DEG  to 800 DEG  F. and a pressure of up to 2000 p.s.i.g. and in the presence of hydrogen with a catalyst comprising a hydrogenating component disposed on an aluminacontaining refractory oxide support, the support being modified by the inclusion therein of from 0.01 to 5% by weight of the total catalyst of either lithium or magnesium. The hydrogenating component may be a platinum-group metal, or molybdenum sulphide or oxide combined with nickel or cobalt sulphide or oxide.  The support may be alumina, alumina-silica or alumina-boric and may contain phosphorus or fluorine.  In examples the catalyst is compared with an otherwise similar material containing potassium but no lithium or magnesium.
Patent GB-1110957-A (GB)
Title: Production of organosilanes
Inventor: BONITZ ECKHARD
IPC: C07F7/18
Filed: 1965-08-27
Abstract: Organosilanes are prepared by reacting finely divided Si in a liquid medium with a substituted or unsubstituted alcohol or phenol, and reacting the silane formed with an organic unsaturated compound.  The Si used may be any commercial grade of 80-99% purity and containing no additional catalysts.  By "finely divided" is meant a particle size of 100-0.1 micron.  The first reaction stage is preferably conducted in a liquid organic diluent or Si compound, the product silane being recovered prior to reaction with the unsaturated compound. The silanes may be monomers or polymers and in the latter case cyclic or acyclic. The reaction in the first step may be conducted at atmospheric or above pressure, and usually at below 250 DEG  C.  The reaction of the silane with the unsaturated compound is effected under conventional catalytic conditions.  The products may be hydrolysed with water to yield silanols, and polysiloxanes.

Title: A hydraulic system incorporating improved means for controlling leakage in a ram andcylinder
Inventor: HINDE PHILIP BENJAMIN
IPC: B30B15/00
Filed: 1959-11-06
Abstract: 889,128. Stuffing-box substitutes. AVERY Ltd., W. & T. Jan. 16, 1961 [Nov. 6, 1959], No. 37669/59. Class 122 (5). [Also in Group XXIX] An hydraulic system for controlling leakage in a ram 1 and cylinder 2 apparatus, such as a press or material testing machine, comprises at least two spaced annular channels 8, 9 in the sliding surfaces of the cylinder or the ram, and a packing ring 20 provided between the cylinder and ram, the channel 8 nearer the working chamber 3 of the cylinder being connected to a source of liquid 7 at substantially the same pressure as that supplied to the working chamber, and the second channel 9 being connected to a valve 13 which permits free exhaust of liquid from the channel at relatively low pressure and a constant rate of flow above a predetermined pressure. The leakage between the ram and cylinder is controlled at the relatively low pressure by the flow between the channels and at higher pressures, the packing is progressively brought into action by the pressure of - liquid between the second channel and the packing. The working chamber 3 is connected by a line 4, control valve 5, which may be of the type described in Specification 777,343, and a line 6 to a pump 7 which is also connected by a line 10 and pressure-reducing valve 11 to the first channel 8. The second channel is connected by a line 12 to the valve 13 which is also connected to the valve 5 and exhaust. The valve 13 has an adjustable orifice 14 and a plunger 15 on one side subjected to the pressure of a spring 16 and the pressure at the orifice and, on the other side, connected by a by-pass 18 to the pressure in the line 12. When the pressure in the working chamber 3 is low, the plunger is moved by the spring to a position wherein the flow from the channel 9 is unrestricted and leakage from the ram is controlled by the flow from the channel 8. As the pressure in the chamber 3 rises, the pressure in channel 9, and hence line 12 and by-pass 18, increases, causing the plunger 15 to move and pass a constant rate of flow so that the pressure in channel 9 builds up to bring the packing into operation.

Abstract: 993, 096. Automatic speed control. EATON MANUFACTURING CO. Oct. 9,1963 [Oct.15, 1962], No. 39898/63. Heading G3R. The desired speed of a driven shaft is determined by adjustment of potentiometer 37 which controls the energization of coupling-coil FC. The shaft carries an A.C. tachometer generator G1, connected to rectifier 23 and filter network 24, whose output comprises a composite signal having a ripple component. Transistor T2 conducts only when the instantaneous value of the composite signal is less than the reference potential derived from potentiometer 37. The resulting pulses at the output of transistor T2 are amplified by transistor T3 and applied to the base of power transistor T4 which is pulsed repetitively between its conductive and non-conductive states. The average power supplied to the coil FC is thereby regulated to maintain the speed of the driven shaft at the desired value. A regulated power supply for the potentiometer 37 comprises diodes 41, 43 connected to winding 49 of a power transformer or driving motor. A filter network consists of resistor 53 and capacitor 55, a voltage-regulating transistor T1 being associated with Zener diode 59.
