Patent GB-951637-A (GB)
Title: Method for preparing an alumina catalyst base
Inventor: BRAITHWAITE DAVID GORDON
IPC: C01F7/141
Filed: 1960-09-15
Abstract: Alumina monohydrate catalyst base in microspherical form, is prepared by reacting an aqueous solution of alkali metal carbonate and a water soluble aluminate, adjusting the pH to less than 7 with an acidic water soluble aluminium salt, such as the sulphate and then adjusting the pH to between 7.5 and 9.5 with the addition of a water soluble aluminate, followed by heating to 75-150 DEG  F. to precipitate the monohydrate. The precipitate is thereafter spray dried, without washing, at a temperature of 150 to 325 DEG  F. to form microspheres and subsequently washed free from contaminants. After drying the microspheres may be treated with active metal catalysts and thereafter extruded through 1/8 or 1/16 inch orifices. The alkali metal carbonate employed, preferably sodium or potassium, should have a concentration less than 1% and the aluminate solution should be of 80% concentration. The mol. ratio sodium carbonate/alumina should be from 0.05-1 to 1. According to Example 2 the formed microspheres were slurried in water and finely divided MoO2 and CoCO3 were successively added; the suspension was heated to 180 DEG  F. before flash drying to form a catalyst stock which was extruded to form catalyst particles. Reference is made to hydrogen treating and desulphurizing gas oil.

Title: Improvements in four-stroke cycle internal combustion engines
IPC: F02B1/00
Filed: 1930-07-21
Abstract: 344,717. Four-stroke engines. TETLOW, C. E., The Grange, Withins Road, Hollinwood, Oldham. July 21, 1930, No. 32126/29. Drawings to Specification. [Class 7 (ii).] In a four-stroke-cycle engine, a fan or other type of pump is employed to withdraw the exhaust gases and create a partial vacuum in the cylinder, into which combustible mixture is admitted or forced before the piston has completed the exhaust stroke. The compression and clearance spaces are therefore filled with combustible mixture before the piston commences the inlet stroke. The Specification is accompanied by diagrams illustrating piston positions and valve openings for the cycle according to the invention, and for a modification thereof, in which the inlet valve closes at the end of the compression stroke instead of at about a crankangle of 17‹ beyond it.

A method of straightening and untwisting solid or hollow metal or alloy sections comprises applying a slight tension to the section, surrounding or enflanking it along substantially its full length with two or more mould or die members, and applying to it a tension to exceed the elastic limit of the metal whilst bringing the mould or die members closer to one another. A bent and twisted two-finned tube P is gripped at each end by jaws of heads, moved away from one another to place the section under slight tension, and is rotated to untwist it. A mould member 4 is lowered, by lever and link means 7, 6<SP>1</SP>, 5<SP>1</SP> to co-operate with a mould member 3 to engage the fins of the tube P and one head is moved away from the other to stretch the tube beyond its elastic limit and thus straighten it. In another embodiment, Fig. 3 (not shown), for straightening and untwisting Y-sectioned bars, two upper mould members (10), (10<SP>1</SP>) are moved in on levers and two lower mould members (16), (16<SP>1</SP>) by a jack operating through toggle means.

Abstract: 521,050. Thermionic valves. STANDARD TELEPHONES & CABLES, Ltd. Nov. 11, 1938, No. 32866. Convention date, Dec. 31, 1937. [Class 39 (i)] In a valve with a filament cathode comprising a number of loops arranged parallel on a cylindrical surface the ends of the loops are held in elongated eyes secured to an insulator carried by a central rod, so as to allow for expansion. Fig. 1 shows a valve the envelope of which consists in part of the anode 101 and in part of a glass bulb 5, the joint between them being protected by a screen 12. At the end of the bulb are portions 7 to which are sealed metal tubes 8 gripping rods 41, 41<SP>1</SP>, the joints being protected by screens 57. To the rod 41 is attached a piece 123 carrying three rods 124, and to the rod 411 a piece 123<SP>1</SP> carrying three rods 124<SP>1</SP> and a central rod 125. The rods 124, 1241 are spaced from each other and the rod 128 by pieces 126, 126<SP>1</SP> insulated from the rod 125 and held between stops 127 on the rods 124, 124<SP>1</SP>, which may consist of wire coils. On the end of the rod 125 is a triangular insulating block 130 carrying three metal rings 133, Fig. 6, to which are attached elongated eyes 136 through which the bights of the filament pass. The grid consists of wire wound on rods 14 carried by a ring 104 supported on a hollow conductor 106 welded to a cap 103 on a lateral projection 109 on the bulb. When used with polyphase current the loops of the filament may be interleaved to increase uniformity of emission. In a modification, the central rod 125 is sealed direct to the bulb and the rods supporting the filament are bent to ensure parallelism of the portions of the filament. The Specification as open to inspection under Sect. 91 describes other forms, in particular that shown in Fig. 1 (Cancelled). In this form glass or like bulbs 5, 6 are attached to both ends of the anode 1. The grid 16 is carried on a sleeve 21 welded to a metal portion 11 of the bulb 6. The grid lead is formed by a tube 26 welded to the portion 11 and carrying cooling fins 29 and cable attachments 36. The cathode filament 35 is connected to rods 36 and a disc 37 sliding on a central rod 49. The filament is carried by rods 39 attached to bars 41 secured in sleeves 55 welded to metal caps 59 sealed to corresponding portions of the bulb 5. To the caps 59 are connected flexible leads 61 secured to terminals 65. The rod 49 which centres the filaments is secured to a plate 42 engaging an insulating member 46 surrounding and secured to the bars 41. In a further modification the cathode arrangements are similar to those just described, but the grid is supported from a terminal in the side of the bulb 5, the bulb 6 being dispensed with. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to apparatus for electrically precipitating suspended particles from fluids
IPC: B03C3/66
Filed: 1921-12-09
Abstract: An electric precipitator having electrodes of constant polarity is supplied with current from a transformer or other source giving an insufficient electric pressure, through inductance or capacity, or both, in order to increase the electric pressure to the required value by means of current oscillations. The maximum current may be limited by the same means, so that dangerous sparking is prevented. The current may be furnished by a transformer through mechanical rectifiers and a device for interrupting the direct current at short intervals; by varying the frequency of interruption the pressure can be controlled.  Or alternating current may be supplied through a switching device which cuts out the half-waves of one polarity.  The capacity or inductance may be obtained by suitably arranging the conductors themselves.

Class 40(6) [Also in Group XL(a) ] The electron beam of a travelling-wave tube acting as a pulse amplifier is pulsed, the pulses having such a duration and spacing that when reflected waves arrive at the critical point of selfexcitation, i.e. the point at which the power of a portion of a wave which has been reflected at the output of the wave retarder and reflected again at a point on the wave retarder is equal to the power of the travelling wave moving in the same direction and required to be amplified by the tube, they do not interact with electrons, so the generation of self-excited oscillations is prevented and the need for high frequency attenuating means in the travelling-wave tube no longer exists. In the arrangement shown a stream of electrons from a cathode 14, Wehnelt cylinder 13 and control anode 12 is passed to a collector electrode 15 through a helix 10 having an input end E and an output end A. Pulses of the requisite duration and spacing are applied from a generator 16 to the control anode 12. High frequency oscillations are applied to a gating circuit 19 which is also connected to the output of the generator 16 so that the high frequency oscillations are applied to the input E in pulses synchronous with the pulses of electrons.
