Title: Improvements in automatic turn compensators for aircraft
IPC: G05D1/04
Filed: 1958-09-08
Abstract: 856,678. Automatic control systems for aircraft. GENERAL ELECTRIC CO. Sept. 8, 1958 [Sept. 11, 1957], No. 28736/58. Class 38 (4). In an automatic turn compensator for an aircraft the proportion of a signal/dependent on the secant of the angle of bank, causing operation of a control surface, is dependent on the integrated difference between the secant of bank signal and a signal from an angular accelerometer. To prevent change of altitude during turns effected by an automatic pilot a signal dependent on the secant of the angle of bank of an aircraft is derived from a graded potentiometer 26, Fig. 3, associated with a gyro 32, and applied through a potentiometer 36 to a followup servo-system 48 operating elevators 18. The difference between signals from secant generator 26 and an angular accelerometer 22 are maintained zero by applying them in opposition to operate an integrating motor 61 which adjusts potentiometer 36.

Abstract: 911,260. Variable-speed control. LONDON RUBBER CO. Ltd. April 17, 1961 [Aug. 23, 1960], No. 29142/60. Class 80 (2). [Also in Group V] Formers 54 are lowered into and raised out of a bath 12 by a hoist 11 of a dip-moulding machine (see Group V) at varying speeds. The hoist is driven by a motor 16 coupled by an infinitely variable change-speed gear 17. As the hoist descends at high speed a plate 34 and pin 49 move upwards changing the slope of a cam bar 47 pivoted about a slide member 31. When a beam of light from a lamp 52, directed on to a photo-electric cell 53 is obstructed by the former 54, a switch is operated to clamp the slide member 31 to the plate 34 and they both move upwards until the former 54 is fully immersed, the apparatus is then in the dotted position. The follower 28 is then projected into the path of the cam bar 47 and as the former 54 ascends, the plate 34, the slide member 31 and cam bar 47 move down deflecting the follower 28 to the left and moving the speed gear lever 23 progressively to the low-speed position until the former 54 clears the liquid, so that minimum speed is attained just as the former leaves the liquid irrespective of the length of the former, then the follower 28 rides off the end of the cam bar 47 and the speed gear lever 23 returns to the high speed position for the remainder of the ascent.

Patent GB-747663-A (GB)
Title: Improvements relating to catalysts
IPC: B01J21/20
Filed: 1952-11-27
Abstract: Catalyst containing oxides of cobalt and molybdenum deposited on or incorporated with alumina is treated at an elevated temperature in the vessel in which it is to be used, with a flourine-containing compound, so that flourine is introduced into the catalyst (e.g. in an amount of 1-4 per cent by weight) and distributed evenly therethrough.  The fluorine compounds may also contain chlorine, bromine, or iodine, and may be mixed with a diluent gas, e.g. air, nitrogen, or hydrogen; specified compounds are dichlorodifluoromethane, tertiary butyl fluoride, boron trifluoride, and hydrogen fluoride.  The process may be used for the preparation of catalyst or for the restoration of the fluorine content of catalyst which has been regenerated by heating in the presence of oxygen.  If the catalyst is held in contact with the fluorine-containing compound at an elevated temperature, the fluorine is distributed evenly throughout the catalyst. Alternatively, the compound may be added to a stream of gas passing over the catalyst or to a liquid or vaporized hydrocarbon feed; in these cases subsequent treatment to distribute the fluorine evenly is carried out, for example, by removing the catalyst from the reactor and mixing thoroughly, by treatment in the reactor at 500 DEG -1100 DEG F. with a stream of gas or vapour containing a small percentage of water vapour, or by subjecting the catalyst to one or more short processing periods each followed by regeneration in the presence of oxygen.  The catalysts may be used in a hydrocarbon autofining process as described in Specifications 654,152, 663,038, 669,536, 669,552, 669,553, and 679,175, and particularly in a process carried out at equilibrium pressure as described in Specification 697,083. Specification 719,627 also is referred to.

Title: Improvements in and relating to underreamers and oversize hole drilling tools for drilling boreholes such as wells

Filed: 1936-11-04
Abstract: 473,112. Well-drilling tools. ZUBLIN, J. A. Nov. 4, 1936. No. 30071. [Class 85] A tool for under-reaming a well casing, or for boring a hole larger than a casing through which it is adapted to pass, comprises a shank and a cutter rotating on an inclined bearing on the shank, the cutter having a rotational position in which its vertically projected outline is a circle and a second position in which its vertically projected outline is an oval. A shank 10 has an inclined portion 12 which, with a pin 14 threaded thereto, forms a bearing for a cutter 15 retained on the bearing by balls 26. The cutter overlaps a flared bore 19 in the - bearing to deflect flushing fluid for lubrication of the bearing. In the position shown in Fig. 1, all the cutter teeth in vertical projection fall within a circle of the inner diameter of the casing 16, so that the cutter can pass through the casing ; on the plane A-A, however, the teeth lie substantially in an oval, so that when the cutter turns through 90‹, some teeth project outside the diameter of the casing. In the plane B-B, teeth to the right of the line C-C are arranged substantially to contact the casing and the teeth to the left of line C-C are arranged symmetrically. Teeth intermediate the planes A-A, B-B are arranged to correspond. Of the teeth below the plane A-A, those in preferably the upper two rows are similarly designed symmetrically and so that those to the left of line C-C contact the casing, while the lower teeth are arranged substantially in a spherical outline. The cutter may be arranged so that its centre O is to one side of the axis D-D of the shank. When the tool is to be lowered through the casing, the cutter is held in desired position by a plug 53 of wood &c. inserted in the flushing fluid outlet 51 and held by a rubber &c. band 55. In a modified form, Fig. 2, the teeth 31a above the plane A-A have two cutting edges at right-angles. Specifications 263,392, [Class 85], and 444,696 are referred to.
