Title: Aircraft arresting apparatus
IPC: B64F1/02
Filed: 1971-05-17
Abstract: 1332746 Aircraft arrester GULF & WESTERN INDUSTRIAL PRODUCTS CO 17 May 1971 [20 May 1970] 15461/71 Heading B7G An aircraft arrester comprises, on each side of an aircraft runway A, a reel D rotatable about a substantially vertical axis, having wound thereon a flat elongated tape E which is in contact with means J comprising at least one sheave rotatable about a substantially vertical axis and closely adjacent the reel and arranged so that during coiling and uncoiling the tape is in contact with the sheaves over a total angle of at least 90 degrees. The tapes E are connected by a pendant 24, which may be a steel cable, a net or a band of synthetic material, and each reel D is provided with a friction or hydraulic brake (G), Fig. 2 (not shown). Prior to use the tapes are held in tension by frangible holding means 52. Each means J may comprise two sheaves 62 and 64 mounted on the same base 42 as the reel D; the wheels may be barrel-shaped. Since the total area of tape in contact with the sheaves, and the component of the tension in the tape radially of the wheels are such that there is a high frictional force opposing axial movement of the tape on the wheels, vertical oscillations in that part 56 of the tape E on the side of sheave means J remote from the reel caused by impact of an aircraft with the pendant 24 are not transmitted to that part 60 of the tape between the reel and the sheave means, and moreover the tape is able to be rewound evenly on to the reel. Further means K, each comprising sheaves 92 and 94, may be provided closer to the runway A. The apparatus described can arrest an aircraft even if the sheave means K are omitted; however if each means J comprises only one sheave the apparatus can be used for aircraft landing in a single direction only. When the sheave means K are omitted it is preferable for the sheaves of the means J to be arranged so that a line (84), Fig. 11 (not shown) connecting their rotational axes intersects the tape part 56 at an acute angle.

Title: Improvements in or relating to the manufacture of quaternary ammonium compounds
Filed: 1938-05-27
Abstract: 515,477. Quaternary ammonium compounds. DEUTSCHE HYDRIERWERKE AKT.- GES. May 27, 1938, No. 15909. Convention date, May 27, 1937. [Classes 2 (iii) and 15 (ii)] Quaternary ammonium compounds are prepared by the reaction of amides or esters of amino aliphatic carboxylic acids having at the amide nitrogen or in the ester group no cyclic residues but at least one aliphatic residue containing at least six carbonatoms with mineral acid esters of aliphatic, fatty aromatic, cycloaliphatic or heterocyclic alcohols. The reactionis preferably carried out by fusing the reactants together. As parent materials there are specifically mentioned : dimethylaminoacetic acid undecenyl amide, dimethylaminoacetic acid dodecyl amide, #-dimethylamino-alpha-diethylpropionic acid cetyl ester. In examples (1) Benzyl chloride is added to fused dodecyl amide of piperidinoacetic acid. (2) Piperidinoacetic acid dodecyl ester is heated with benzyl chloride for 8 hours and then treated with water to remove the excess of unreacted benzyl chloride. (3) Dimethylaminoacetic acid dodecylamide is heated for several hours with benzyl chloride and the crystalline mass obtained triturated with decahydronaphthalene. The products of the invention are crystalline solids and are distinguished by their solubility in water, their insensitivity to the hardness promoting constituents of water, their soap-like action and their strongly disinfectant action against staphylococci and typhus bacilli.

Title: Improvements in electric remote control devices

Abstract: 864,714. Magnetic amplifiers. BROOKE, W., and HOWE, H. May 11, 1959, No. 16023/59. Class 40 (9). A controlled saturable reactor in the circuit between an A.C. motor M, Fig. 1, and singlephase lines L1, L2 comprises two cores A, B, provided with respective main windings PA1, PA2, and PB1, PB2, control windings NA1, NA2 and NB1, NB2, and optional separate feed-back windings SA1, SA2 and SB1, SB2, the main windings being connected in seriesparallel with a rectifier T1 linking the midpoints W1, W2 of the parallel circuit, and arranged so that windings PA1, PA2 are in different parallel branches and act in one sense in relation to the control windings on core A, while the windings PB1, PB2 also in different branches act in the opposite sense in relation to the control windings on core B. The rectifier T1 completes circuits for second harmonic currents which arise in the main windings each time a core saturates, the harmonic currents providing a positive feed-back action by circulating in the two closed paths comprising windings PA1, PB2 and PB1, PA2, and the common rectifier. When the optional separate feed-back windings SA1, SA2, SB1, SB2 are provided, they are connected with a rectifier T2 to form similar closed circuits as the main windings and rectifier T1, the second harmonic currents being generated by induction. The rectifier T1 may then be omitted. A modified arrangement of the feed-back windings is shown in Fig. la which permits the winding pairs SA1, SB1 and SA2, SB2 to be replaced by single windings common to both cores. It is stated that the main winding mid-points W1, W2 may be linked by a resistor or a resistor Rn in series with a reversed rectifier T1E, Fig. 11, to provide negative feedback. The arrangement may be applied to a three-phase system L1, L2, L3, Fig. 9, supplying a star or delta-connected motor, each phase being provided with a similar reactor C1, C2, C3 the control windings of which are connected together in series-parallel, Fig. 10, and energized over rectifiers T6 and a transformer R from the three-phase system. The connection of the control windings, which may include the links shown in broken lines, suppresses induced currents which would otherwise circulate in the windings. A choke N is provided for the same purpose in Fig. 1.

Classes 78 (4) and 104 (2). A calling turntable is associated with runways which provide substantially tangential multiple mine cage inlet runways and a single substantial tangential outlet runway or viceversa. A mine car handling plant at a pit head, shown in Fig. 1, comprises a pair of turntables A and B arranged one at each side of a pair of cages C, C<SP>1</SP> with two lines of track D, E respectively serving the two cages which are alternately raised and lowered. The cars are directed on to the turntable B whence they are delivered to an outlet track F and on to a rotary tippler G where they are emptied. The empty cars are delivered from the tippler G to the turntable A and then on to track D or E to the cage C or C<SP>1</SP>. A selector beam H diverts the cars on to track D or E. Decking N forms the guiding means round the turntables A and B. The turntable A is provided with a freely rotatable disc M to guide the cars from the inner inlet track E to the outlet track F. The cars from the outer inlet track D are directed by a guide rim on the periphery of the turntable A to the outlet F. The turntables may be conical to assist the passage of the cars from an inlet runway near the centre of the turntable to an outlet runway near the perimeter of the turntable or vice versa. The turntables may have a stepped or tiered deck, as shown in Figs. 2 and 3, the tiers A<SP>1</SP> of the turntable A imparting an outward tilt to the cars O. The turntables are also provided with an inner retaining curb guard P to retain the cars on the inner runway and an outer retaining guard Q. The two cages C, C<SP>1</SP> may be replaced by a single cage having two tracks passing therethrough and counterbalanced by a weight K. Simultaneous delivery of cars from the tracks D and E is prevented by a retarder stop L provided in one of the lines. Specification 687,488 is refered to.

Pile fabrics.-In a process for transferring hairs and feathers from their natural support to fabrics, leather, &c., the furs are stretched and secured by means of sewing holes 2 to flat plates 1, which are introduced into freezing-vats 3 in a direction opposite to that of implantation of the hairs &c., so that these rise upright. The vats are provided with guides &c. for the plates and for movable partitions 6<1> when these are used. The water in the vat is then frozen, and the plates with the frozen skins thereon are removed. Several end frozen blocks may be placed together and frozen again. The top layer of the block is next thawed, dried and treated with a coating, after which the fabric intended to form the final support for the hairs. &c. is applied by means of another coating. Finally, the product undergoes the usual finishing operations of cleaning, drying, dyeing, lustering, &c. Instead of water, a substance such as fat, wax, or paraffin may be used especially when glue is used as a coating. Specifications 6185/11 and 18237/11 are referred to.
