Patent GB-1107276-A (GB)
Title: A catalyst and a method for the production thereof
Inventor: MIQUEL JEAN
IPC: B01J27/13
Filed: 1965-07-21
Abstract: Hydrocarbons are reformed in the presence of a catalyst made by impregnating Al2O3 with an aqueous solution containing HBF4 and H2PtCl6 in specified proportions. Typical operating conditions are:-temp 400-550 DEG  C ; press. 1-60 atmospheres, S.V. 0.5-8 and H2. rate 2-15 mols. per mol. of hydrocarbon. Examples describe the reformation of a charge consisting of 59.7% paraffins, 31.2% naphthenes and 9.1% aromatics.  A R.O.N. of 96 was obtained after 600 hours.  The catalysts are said to be useful for isomerization, hydrocracking, hydrogenation and dehydrogenation.ALSO:Reforming catalysts are made by treating Al2O3 with an aqueous solution of HBF4 and H2PtCl6 in molar preparations of 3.5 to 4.5:1 and drying and activating the product.  Use of e - and g - Al2O3 is mentioned and activation takes the form of high temperature heat treatment. Catalysts may contain 0.5% Pt; 0.65% F; 0.41% Cl and 0.1% B.

Abstract: 736,104. Brick kiln doors. BUTTERWORTH, B. Dec. 8, 1953 [Dec. 8, 1952], No. 31097/52. Class 51 (2). In a continuous brick kiln of the multiple chamber type having openings 1 in the outer wall 2 of the same size as the chamber arches, a massive door of prefabricated sections 3 extends over the full height and width of the opening. Each section 3 comprises a refractory concrete base 4 slotted at 5 to receive the forks of a lifting truck, a facing of refractory bricks 6 bonded as at 7 into a backing 8 of common bricks or clay hollow bricks and vertical tie rods 9 located near the cold outer face. The tie rods, which extend between a steel channel member 10 laid across the top of the section and the concrete base 4, have heads 11 in the base and upper nuts 12 with springs 13 to allow for differential expansion and contraction. The vertical edges of the sections are provided with rebates (Fig. 4, not shown) or offsets (Fig. 5, not shown), so that a slot is formed between abutting sections to receive a sand seal. The pavement outside the openings 1 is sloped downwardly to retain the sections in position against the kiln wall. The door may be divided horizontally as well as vertically.

IPC: F02C7/22
Filed: 1960-09-09
Abstract: 932,386. Centrifugal and axial-flow pumps. ROLLS-ROYCE Ltd. Sept. 1, 1961 [Sept. 9, 1960], No. 31220/60. Class 110 (1). A pump for handling liquid containing gas comprises a first impeller for imparting simultaneous axial and centrifugal movement to the liquid, whereby to tend to move the liquid radially outwardly to a greater extent than the gas, a first outlet duct arranged to receive the radially innermost flow of fluid from the first impeller, a second, centrifugal, impeller having a central axial passage through which the radially innermost flow may pass, and a second outlet duct surrounding the second impeller. A submersible booster pump for a gas-turbine engine fuel system comprises an axial-flow impeller 50 in which bubbles of air and vapour tend to separate out centrifugally from the liquid fuel, whereby the bubbles are mainly confined to the radially innermost part of the flow from the impeller 50. This part of the flow passes back to the fuel tank through ports 55 in a rotating chamber 48, while the substantially bubble-free radially outermost part of the flow passes through ports 53 to centrifugal impeller vanes 52 and thence to a volute 54. A deflector 56 may be provided. In alternative embodiments, the rotating chamber 48 is replaced by a centrifugal impeller having a large inlet eye connected to the pump shaft by spokes, the radially innermost part of the flow passing upwardly between the spokes and then returning radially outwardly to the fuel tank below a deflector plate. The radially outermost portion of the flow is delivered by the centrifugal impeller to a volute. The axial-flow impeller may extend partly outside the inlet to the pump casing whereby it causes turbulence in the fuel in the tank to assist in dispersion of the air and vapour in the fuel. The axial-flow impeller may comprise a single helical vane, stationary radial vanes being located at the exit from this impeller to straighten the flow before it enters the centrifugal impeller.

[Class 35.] The bars of a squirrelcage motor having stator windings adapted to give different pole numbers are divided into groups so connected through resistances that when the motor is running on a low-pole number the effective resistance of the winding is greater than when running on a high-pole number, the object being to give more effective braking in motors used for lifts and like purposes. Fig. 1 is a diagram of connections for a motor having 32 bars and stator windings for four and eight poles. The bars are divided into groups of eight alternately connected to end rings 5, 7 at one end and 6, 8 at the other, the end rings being connected through resistances 9 .. 12. The single arrows show the course of the current when the motor is running on four poles and the double arrows when it is running on eight. Fig. 4 shows the construction of the connections. The bars 53 of one set project beyond those of the other and are braced to a ring 49. The bars of the other set are connected to a smaller ring 50 through arcuate packing pieces 56. The resistances are constituted by strips of sheet metal 52 extending from a ring 51 to the rings 49, 50. Connections for a motor having 32 bars and four, eight, or sixteen poles are also described.

In operation the shift rod 3, in its upward movement from neutral range (shown), takes along the selector fork 2 to establish fifth ratio. In its downward movement it releases fifth ratio, and subsequently releases at 26 the fifth ratio fork 2, which is thereafter prevented from further downward movement by abutting a stationary projection 9, after which the rod 3 can make further downward movement for establishing reverse. During subsequent upward movement towards neutral, the fork 2 is initially moved by a snap ring 27 on the shaft 3.
