Title: Improvements in automatic brakes
IPC: F16D59/00
Filed: 1920-08-07
Abstract: 174,963. Sch³rmann, C. Aug. 7, 1920. Locking by frictional detents.-A helical spring serving as a friction ratchet or detent is used in combination with a brake for preventing movement of a rotary mechanism in one direction. As shown in Fig. 2, the spring 6 is enclosed in a casing, of which the part 4 is secured to a revoluble shaft 1, for example the cardan shaft of a motor-vehicle, and the other part 5 of the casing is formed on a pulley 2, to which a brake, consisting of a pair of blocks with screw-and-nut actuating mechanism 31, is applied. When the shaft 1 tends to rotate in one direction, the friction between the casing and the spring tends to uncoil and expand the spring so as to couple the two parts of the casing together, and thus to prevent the motion as long as the pulley 2 is held fast by the brake. Fig. 5 shows the application to an elevating machine or hoist. The helical spring is interposed between the fixed bearing 7 and a brake member 14, the other brake member 13 being provided on a pinion 10 which is free to move laterally to a limited extent and is in engagement with a screw-thread 9 on the shaft 8 provided with the hand-chain wheel 12. When the shaft is turned by the wheel 12 in the directicn of the arrow, the pinion 10 is moved laterally by the screw 9 so as to press the brake members together, a collar 16 on the shaft serving as an abutment. All these members thus revolve with the rope drum. When the hand-wheel is released, the load on the rope-drum causes the brake members to be pressed together as before, but tends to turn them in the opposite direction. Turning in this direction is, however, resisted by the uncoiling of the spring 17, which in these circumstances couples the members 7 and 14. The load cannot, therefore, descend upon releasing the wheel 12, but it may be lowered by turning the wheel in the opposite direction to that of the arrow. The spring 17 may be attached at one end of the bearing 7 or to the brake member 14.

Title: Process for the production of derivatives of hydroxylamine
Filed: 1961-06-28
Abstract: In a process for the production of hydroxylamine amino-alkylated on the oxygen atom, a hydroxylamine-N-disulphonic acid salt is reacted in an alkaline medium with an ester of an aminoalcohol and an acid, or with a salt of such an ester, and the N-positioned sulpho groups subsequently are split off.  The amino group of the ester may be free or partially or completely substituted by alkyl, cycloalkyl, aryl, aralkyl or heterocyclic groups, or the amino nitrogen may form part of a heterocyclic ring, e.g. a piperidine, morpholine, thiomorpholine or piperazine ring.  In an example sodium nitrite is reacted with sodium bisulphite in aqueous solution to obtain a solution of the sodium salt of hydroxylamine-N-disulphonic acid; this solution is then reacted with potassium hydroxide and a solution of b -(diethylamino)ethyl chloride hydrochloride, after which it is made acid and refluxed to remove the sulpho groups, and worked up to obtain O-[b -(diethylamino)ethyl]-hydroxylamine.
Patent GB-740698-A (GB)
Title: Improvements in or relating to aerial systems
IPC: H01Q21/12
Filed: 1952-09-18
Abstract: 740,698. Aerials. GENERAL ELECTRIC CO., Ltd., BLOCH, A., MEDHURST, R. G., and POOL, S. D. Sept. 4, 1953 [Sept. 18, 1952], No. 23466/52. Class 40 (7). Relates to aerial arrays of n closely spaced elements (n # 3) such that at least adjacent elements have mutual resistances that are appreciable relative to their self resistances. In such an array the voltage across the terminals of the mth element can be written where I l  is the current in the lth element and z lm  = r lm  + jx lm  is the normalized mutual impedance between elements l and m. Thus the voltage Em can be considered to be made up of two components, one derived from the self and mutual resistances of the mth element and the other from the self and mutual reactances of that element, the first component being defined as the directive voltage #m and according to the present invention the relative magnitudes and phases of the currents in the elements are such that the moduli of all the element " directive voltages " are substantially equal but their relative phases differ in the same way as the variation in instantaneous value of a plane sinusoidal electromagnetic wave travelling across the system in the direction of maximum gain. One of the elements may be parasitic and if the algebraic sum of the power supplied to a group of two or more elements is zero or negative, those elements may be interconnected to form a parasitic group; in the latter case the excess power may be dissipated by a resistance. For a broadside array the " directive voltages " will be of equal magnitude and in phase. The invention is described as applied to an end-fire array, Fig. 2, comprising four parallel #/ 2  dipoles 1, 2, 3, 4 having maximum gain in the direction of the arrow 5, the spacing between adjacent dipoles being #/ 5 . Each dipole, e.g. 1, Fig. 3, is connected to a balanced two-wire feeder 6 through a network 7 of lumped reactances 8, 9 and 10, the length of feeder 6 between adjacent networks 7 is #/ 2  and includes a 180- degree twist and the feeder 6 is coupled to a coaxial cable 12 by a matching transformer 13. The component values of the networks 7 are chosen so that the relative amplitudes of the currents in dipoles 1, 2, 3 and 4 are 8.2, 18.4, 18.4, 8.2 respectively the relative input powers being + 340, + 2288, - 539, - 1336, i.e. power from dipoles 3 and 4 is fed back to dipoles 1 and 2 and it is arranged that the conductance of the four networks 7 in parallel is approximately equal to the characteristic admittance of feeder 6.
