Title: Improvements in or relating to automatic pilots for aircraft
IPC: G05D1/08
Filed: 1948-10-08
Abstract: 662,852. Control of two A.C. motors. BENDIX AVIATION CORPORATION. Oct. 8, 1948. [Dec. 21, 1947] No. 26309/48. Addition to 671,336. Class 38 (iii). [Also in Group XXXV] In an automatic aircraft pilot system both the elevator and the associated trim tab are simultaneously operated by separate A.C. servomotors upon a deviation of the craft axis from the normal datum. As shown, the elevator 17 and trim tab 18 are operated in opposite directions by the error signal generated at the gyro horizon 14 through the saturable transformers 50, 51, 65, 66. The elevator motor 15 has phase 78 supplied from the opposed and normally balanced secondary windings 57, 58 of transformers 50, 51 respectively, of which the primary windings 52, 53 are supplied from mains 33. The saturation of the transformers is controlled by means of the windings 62, 63 in accordance with the error signal from valves 31, 32 so as to unbalance the voltages generated in 57, 58 and so drive 15 in the appropriate direction to correct the craft deviation. The energisation of trim tab motor 16 is effected in the same manner by the charge in the saturation of windings 73, 74 of transformers 65, 66. Specification 663,831 is referred to.
Patent GB-488183-A (GB)
Title: Process for the production of phenol-formaldehyde condensation products
IPC: C08G8/28
Filed: 1936-09-29
Abstract: Refers to the condensation of phenol and formaldehyde by processes as described in Specifications 267,901 and 290,963, [both in Class 2 (iii)], wherein the materials are heated in the presence of alkaline condensing agents in such quantity that the condensation product remains in solution, and consists in prolonging the condensation beyond the normal period until the solution becomes cloudy or the resin precipitates out.  About 1,5-3 mols. of formaldehyde are employed per mol. of phenol and after the prolonged condensation the resin solution is neutralized or weakly over-acidulated and the entire batch or the separated resin is distilled and hardened under weakly acid conditions.  The prolonged alkaline condensation may be the final stage of a multi-stage process which may be carried out in a manner similar to that described in Specifications 267,901 and 290,963.  To counteract thickening of the solution, solvents and diluents, e.g. glycol, glycerine, &c. may be added; irregular heating &c. may be avoided by vigorous stirring or blowing-through of gases. In examples, carbolic acid and formaldehyde are subjected to prolonged condensation in the presence of (1) caustic soda and (2) caustic potash together with glycerine; in both examples, neutralization is effected with lactic acid. Specification 451,592 also is referred to.

Title: Method for the production of a number of similar semi-conductor elements.
IPC: H01L29/00

Abstract: 1,179,063. Semi-conductor devices. TRANSISTOR A.G. 4 June, 1968 [1 June, 1967], No. 26523/68. Heading H1K. In a method for producing a number of similar semi-conductor elements from a plate of semi-conductor material, the surface of the plate is divided into strip shaped zones by a plurality of parallel cutting lines, and impurities are diffused into the plate so as to form on its surface strip shaped regions 6, 7 of alternate conductivity type parallel to, and containing at most one of, the cutting lines 4, then cutting the semi-conductor plate along the cutting lines 4 to form elongate semi-conductor bodies and cutting each body into semi-conductor elements of the desired length. In the case where the devices are to be thyristors or triacs the semi-conductor plate has initially three layers of alternate conductivity silicon, the dopants being gallium, phosphorus and boron. Metallized layers are provided to allow contact to be made to the devices. Where the device is a triac the method comprises dividing the lower surface of the plate into strip-shaped regions as before, but dividing the upper surface into squares, Fig. 8, by two sets of cutting lines normal to one another and diffusing separate square zones 28, 29 into the surface at each second point of intersection of the cutting lines so that each square section of the plate surface comprises, in two diametrically opposite corners, regions of the same conductivity type as the middle layer of the semi-conductor plate and in the other two diametrically opposite corners the unaltered surface layer of the other conductivity type. Metal contact layers are applied and the plate is cut up along the cutting lines by means of a fine sand blast. The cut may be of simple V-shape in cross-section or may be basically of V-shape but having its upper corners bevelled.

In the construction shown, core 11 and wool 14 are of steel and are spot-welded together at 15, the wool being wrapped helically around the core; other fastening means such as screws or rivets may be used. The body 16 may consist of a polyvinyl compound including a plasticizer and stabilizer, and be moulded or cast around the wrapped core.

[Also in Divisions F2 and H2] An arrangement for clamping at least one wire comprises a rigid conducting member 4 with grooves 4B and 4C in which the wire or wires can rest, a resilient washer 8 having, in its unstressed condition, two integral divergent portions obliquely set with respect to each other, each having edge portions 9 and 10 also divergent with respect to each other but at a lesser angle than the first portions, and a screw 12 for pressing the washer towards the rigid member to trap the wire or wires between the washer and the rigid member. The washer is of such a size as to extend over the surface of the rigid member and overhang its edges. When the wires 2 and 3 are of relatively small size, the edge portions 9 and 10 engage the edges of the rigid member 4, so that rotation of the washer is prevented. When the wires are relatively large, rotation of the washer is prevented by engagement of the edge portions 9 and 10 with the wires themselves.

Abstract: 891,672. Crates; packaging machines. CELLA MACHINERY Inc. Aug. 10, 1959, No. 27227/59. Classes 18 and 94(1). [Also in Group XXX] A bottle crating machine has means whereby any obstruction preventing a bottle being lowered into a crate, from entering produces relative movement between parts of the bottle carrier supporting carriage, the movement operating control elements which either cause the carrier to withdraw with its load or if the bottles have entered a given distance, to release them before the bottom of the stroke of the carriage. Bottle assembly. A single line of bottles is fed on to a platform 56, Fig. 2, the bottles being pushed in threes on to endless conveyers 44a-44c. The conveyers carry the bottles to an assembly table 112, Fig. 12, where they contact switch plungers 166 causing gripper bars, 210, 212, 214, 216, 218, 220, Figs. 3, 9, on the carrier (see Group XXX) to close on their upper ends. The table 112 descends slightly to release the bottle bases, a gate 154 checks oncoming bottles, Fig. 12, and the switches 166 withdraw. The carrier now moves horizontally along fixed rails 224, 226, Figs. 2, 3, on to rails 228, 230 on a vertically reciprocable carriage 320. Crating bottles. The crates are advanced between rails 360 to be halted over bars 408 the latter being raised by linkage 398, 402, Fig. 5, to lift each crate ca clear of the conveyer. Blocks 432 on the bars and spring-loaded members 458 locate the crate and the carriage 320 descends along rods 322 to crate the bottles. If a bottle strikes an obstruction during descent, the carriage, which is mounted for limited movement on a casting secured to the piston rod 336 of the fluid pressure motor 338 which elevates it, is raised relative to the casting and operates a switch LS-13 whereby the carriage rises without having deposited the bottles. At the top of its travel, it initiates lowering of the bars 408 with consequent withdrawal of the defective crate in the same manner as in the case of a filled one. If the carriage has descended so far before a bottle is obstructed, that the bottles when released will be stable in the crate, the carrier, in rising in response to operation of the switch LS-13, contacts a switch LS9, Fig. 3. This switch causes the bottles to be released. Crates suitable for use in the above machine have sheet metal plate separators 486, 488 with rectangular apertures, and a wire rod base 490, Figs. 9, 10.
