Abstract: 1, 096, 290. Conveying solids in liquids. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Nov. 2, 1966 [Nov. 4, 1965], No. 49151/66. Heading F1R. A method of simultaneously transporting a mineral salt in granular form, e.g. potassium chloride, in a pipeline carrying mineral oil, e.g. petroleum or crude oil, comprises mixing mineral salt granules of diameters up to 4, 000 microns with mineral oil and a stabilizer selected from the group consisting of alkali and alkaline earth metal salts of organic sulphonates, to form a stabilized slurry, and subsequently pumping the stabilized slurry through the pipeline. The mineral salt and stabilizer are separated from the mineral oil at the pipeline terminal, e.g. by filtering or brining. The stabilizer may be an alkyl napthalene sulphonate and may be present from 0À01% to 0À05% by weight of potassium chloride in the slurry. The slurry may comprise 150 parts by weight of mineral salt to 100 parts of oil. When the mineral salt is extracted by brining, the stabilizer can be removed from the brine by acidification, and reused.

Title: Light emitting semiconductor devices
Inventor: DOBSON CHRISTOPHER DAVID
IPC: H01L33/00
Filed: 1963-12-13
Abstract: A light-emitting semi-conductor device comprises a circular or semi-circular slice of semi-conductor material of one conductivity type having two flat parallel faces and a peripheral edge surface normal to the faces and a flat region of opposite conductivity type lying within the slice and parallel to the faces, the region lying within a circular region concentric with the circular slice or a semi-circular region centrally positioned on the same diameter as the semi-circular slice, said circular or semi-circular region having a diameter or length which does not exceed a quarter of the diameter of the slice.  A circular slice of n-Ga As has Zn diffused into it to form a circular concentric P-type region.  The ratio between the diameter of the slice and that of the region is chosen such that light emitted from the PN junction will emerge from the slice without suffering total internal reflection.  For GaAs, the ratio is 4 : 1. For mass production, a silic a coating is provided and Zn diffused in through holes in the silica formed by photo-resist techniques. Discs are cut out concentric with the diffused region and provided with Au contacts on opposite sides.  In other embodiments a circular or semi-circular slice may be provided with a silvered surface to reflect light back through the slice whilst the diffused region may be a right parallelepiped lying within a circular region which has the above diameter ratio.  In the case of a right parallelepiped (Fig. 3, not shown), the region may be positioned so that a Weierstrasse axis of the cylindrical slice passes through the centre of the region.  Thus, any light emitted from the PN junction will be focused at a set point outside the slice.

The assembly is packed with lubricant of the same density as the cage 16 and contained within a "U" section annular housing 20 to keep the lubricant in place despite centrifugal loading.

Title: Method of Regulating a Squirrel-Cage Induction Machine
Filed: 1967-11-01
Abstract: 1,193,979. Control of A.C. motors. LICENTIA PATENT - VERWALTUNGS G.m.b.H. 1 Nov., 1967 [2 Nov., 1966], No. 49659/67. Heading H2J. [Also in Division G3] A squirrel cage induction motor 2 is supplied from a pulse inverter 1 having a control unit 3 for determining the frequency of commutation of the inverter, the motor frequency, and the motor voltage. A main control signal is applied to an integrator 4 connected to a voltage-frequency converter 5 for pre-setting the motor frequency. The outputs of a generator 8 and the integrator 4 are compared and the error signal is applied to a trigger 9 providing feedback to the generator so that it oscillates. Thus, when the main control signal is increased, for example, the commutation and motor frequencies are increased, together with the motor voltage. The flux of the motor is detected by choke coils connected to the motor supply-lines, the reactive currents representing the magnetization current of the motor and hence its flux. The reactive currents are rectified and applied to a Hall converter whose output is amplified by a proportional-integral amplifier shunted by an R-C network, Fig. 2 (not shown). The output of this amplifier modifies the operation of the inverter so that the output voltage is increased when the flux of the motor is insufficient, for example. The output current of the inverter is detected by current transformers 16a, 16b, 16c, associated with rectifier 17 and trigger 18. The triggers 9, 18, are connected to AND-gate 19 for voltage control of the inverter which is switched-off when the current becomes excessive.

Title: Process for the preparation of alumina
IPC: C01F7/34
Filed: 1963-12-18
Abstract: Alumina is prepared by heat treating alumina hydrate precipitated by the process described in Specification 1,071,270 to a temperature above 177 DEG  C. but below 760 DEG  C. and contacting said alumina with water to accomplish chemical rehydration thereof.  The heat treatment may be continued until there is equilibrium conversion of the crystalline alumina to rehydratable amorphous alumina and non-rehydratable gamma alumina, heat treatment at a temperature in the lower portion of the range producing a relatively small portion of the latter alumina and a relatively large proportion of the former and vice versa at a temperature in the higher portion of the range. On contacting the heat-treated alumina with water, substantially equilibrium rehydration of the rehydratable portion to pseudoboehmite is accomplished. Subsequent calcination at a temperature between, say, 399 DEG  to 816 DEG  C. converts the pseudoboehmite gamma alumina.  The alumina may be used as a catalyst support (see Division B1).ALSO:Specially prepared and rehydrated Al2O3 is activated with platinum and used as a catalyst in the reforming of naphtha. Physical properties of the catalyst included are pore size, surface area and bulk density.

Abstract: 1365356 Gas-spring power-storing mechanisms J L GRATZMULLER 4 Nov 1971 [13 Nov 1970] 51261/71 Heading F2S [Also in Division H1] A gas spring has a cylinder 71 in which moves a structure such as a plunger, piston or an arrangement, such as that shown, with an unattached piston 89 while the plunger (in the form of a rod), or a rod such as 79 of the structure, extends out of at least one end, e.g. for linking to a movable contact of an electric circuit-breaker (see Division H1); a chamber 93 between the structure and the cylinder is filled, e.g. by way of a valve 33, with gas (such as H 2 , He or Ne) which under normal temperature and pressure has a density less than that of N 2  and which is under a pressure between 300 and 1000 bars. The spring may include a chamber 87 supplied with hydraulic fluid through an inlet 86 to act on a piston 81 to compress the spring to load it, in which case the piston-rod 79 may have an extension 85 beyond the piston 81 and abutting the spring piston 89. The extension is in a chamber 90 between the pistons and open to atmosphere through an orifice 96. The relative positions of the pistons 81, 89 may be interchanged, Fig. 6 (not shown), so that instead of urging the rod 79 into the cylinder the piston 81 urges it out, until the spring is required to operate and release its stored energy. The spring is released by voiding the chamber 87. In another embodiment, Fig. 7 (not shown), the two pistons 81, 89 are adjacent one another at one end of the rod 79 with which they are integral and are separated by a peripheral groove (97) which, together with radial passages (99) in the rod, forms the intervening chamber 90 and communicates with the atmosphere by way of an axial channel (101) through the rod. The seals for the plunger, piston or piston-rod each comprise a spring-compressed packing 77, 83 or 91 of a number of elastomeric rings of different elastic properties. For a plunger or rod, the seals are stationary. A simple spring, without an hydraulic chamber, Fig. 3 (not shown), having a piston (37<SP>1</SP>) urged into the cylinder (1) by the compressed gas, has a chamber (43), on the opposite side of the piston, which as a breather valve (45) to atmosphere. In another embodiment, Fig. 4 (not shown), a plunger (55) extends out of both ends of the cylinder (1) and has two sections of different diameters for providing the differential pressure and stops (57, 59) on it for limiting its travel. According to which exposed end of the plunger is connected to a member to be moved, the member is pushed or pulled on release of the spring.
