Title: Automatic brake adjuster
IPC: F16D65/56
Filed: 1962-03-16
Abstract: 944,082. Internal shoe drum brakes. BENDIX CORPORATION. March 16, 1962 [March 20, 1961], No. 10200/62. Heading F2E. An automatic adjuster for an internal shoe drum brake of the kind in which the shoes anchor at either end according to the direction of rotation of the drum, by the provision of both anchoring and actuating means between adjacent shoe ends, comprises a threaded member secured into an anchor at one end of each shoe and against the head of which the shoe abuts, the threaded member being rotatable by a pawl- and-ratchet via a strut arranged generally chordally of the shoe and connected to a bell crank pivoted on a fixed anchor engaging the other end of the shoe, the arrangement being such that when the other end of the shoe is disengaged from the latter anchor by the actuating means, the bell crank is rotated and urges the strut towards said one end of the shoe against the force of resilient means which, during subsequent brake release, rotate the threaded member through the pawl-and-ratchet. The adjuster is arranged to operate only during rotation of the drum in the direction opposite to the normal or forward direction. As shown, the brake comprises shoes 18, 20 engageable at each end with an anchor bracket 34 and also actuable at each end by hydraulic cylinders 27. The shoes are normally retracted by springs 36 so that one end of each shoe engages one anchor bracket 34 directly and the other end engages the head 46 of a threaded member screwed into the opposite anchor bracket 34. The head 46 has ratchet teeth 49 engaged by a forked, inwardly bent end of a strut 58 extending chordally of the shoe to a bell crank 52 to which it is pivotally connected at 56. Crank 52 is pivotally mounted at 54 on the adjacent anchor 34 and has a face 55 engageable with actuating link 28 of the adjacent cylinder 27 when the latter is operated during reverse rotation of the drum 12. A spring 66 biases the strut to cause crank 52 to engage a fixed abutment when not engaged by the link 28. The adjuster is inoperable during forward braking when the shoes anchor at their ends bearing directly on brackets 34. During braking in the rearward direction of rotation of the drum crank 52 is moved by the link 28, the shoe anchoring on the head 46. If the movement is sufficient the forked end of the strut slips a tooth on the head 46 so that during subsequent brake release the head is rotated to take up the slack. In the modification of Fig. 6 a bell crank 78 on one anchor bracket is adapted to be entrained by the adjacent shoe end when the brake is applied in reverse rotation of the drum to move through chordally arranged strut 86 a lever 92 pivoted at 94 and formed as a pawl to engage the ratchet teeth 49 of the threaded member, movement sufficient to slip a tooth resulting in rotation of the threaded member on subsequent brake release through the action of a spring 96. Specification 681,765 is referred to.

Abstract: 733,261. Current and voltage measurement and measuring apparatus; measuring bridges; temperature-sensitive resistors. GOSSEN & CO. GES., P. April 16, 1953 [April 17, 1952], No. 10428/53. Class 37. In apparatus for measuring the R.M.S. value of alternating currents and voltages independently of frequency, an A.C. is rectified and applied to energize one coil of a permanent magnet quotient measuring instrument through a constant resistance and the other coil through a current variable resistance whose resistance value is proportional to the square of the mean current therethrough. Fig. 1 shows a device wherein the A.C. in a conductor 1 energizes a bridge rectifier 4 whose output current is connected through a fixed ohmic resistance Rc to coil 7 of a permanent magnet quotient measuring instrument, and to coil 8 of the instrument through a current-variable lamp resistance Ri, to indicate the R.M.S. alternating current on a suppressed zero scale 11 independently of any variations of form factor, frequency, external magnetic fields, permanent magnet strength, and temperature. The resistance Ri varying as the square of the mean value of the current therethrough comprises a positive temperature coefficient tungsten wire 18 (Fig. 5) of thickness less than 20 microns wound in a coil of diameter less than 0.3 mm. and length greater than 4 mm. in which the turn spacing is less than the wire diameter, suspended between short conductors 19 whose cross-section is more than 100 times the wire cross-section and whose ends are disposed close together and fused through an evacuated glass bulb 20 containing the coil. For larger current measurements, the input is coupled to the line through a current transformer (Fig. 2, not shown) while for voltage measurements the input is connected across the line through a series resistance (Fig. 3, not shown). In a modification for voltage measurement (Fig. 4) the rectifier is energized from the line through series resistance 13 and its output is connected through the directional moving coil 7 of the quotient measuring instrument to diagonal 14, 15 of a bridge network having opposite arms comprising a pair of fixed resistances Rc and a pair of variable resistances Ri whose values are proportional to the squares of the mean currents therethrough. The measuring coil 8 of the instrument is connected to the remaining bridge diagonal 16, 17 and alternatively one resistance Ri may be replaced by a fixed resistance Rc and both resistances Ri may be connected in series in one bridge arm.

Patent GB-386621-A (GB)
Title: Improved process for alloying or combining metals of any kind
IPC: C22C1/03
Filed: 1931-04-13
Abstract: A process for the production of alloys, or combinations of metals of any kind, consists in separating a metal from its combination with an acid radical consisting of one kind of atom, e.g. a halide, by a second metal which is to be alloyed with the first metal, the second metal entering into a volatile combination with the acid radical of the first metal compound. If a chloride of the first metal is to be reduced it may be prepared by the direct chlorination of the raw ore. In an example, beryllium chloride vapour is fed into a receptacle containing aluminium. Aluminium chloride is formed and escapes with some unreduced beryllium chloride from the reaction chamber, the reduced beryllium alloying with the excess of aluminium on the application of more heat. The beryllium particles liberated may be fused together instead of being alloyed with an excess of aluminium. The working conditions may be so chosen that the salt to be decomposed is partly solid in the reaction chamber, and the yield of reduced metal may be controlled by adjusting the conditions of temperature and pressure. The reaction may take place in currents of gases which are inert towards, or which participate partly or completely in, the reaction, e.g. nitrogen, hydrogen, or rare gases such as argon, etc.; and such gases may serve to distil metals such as aluminium, magnesium, &c., into the reaction chamber, or to render non-volatile compounds produced by the reaction volatile during the process, as when beryllium sulphide is reduced in hydrogen, hydrogen sulphide being formed leaving the beryllium in the chamber to alloy with the second metal. Similar reactions occur with azides when hydrogen is used. The working temperature may be so arranged that the formation of the alloy takes place substantially or completely at the temperature of the reduction without additional heating. Heat for the initiation of the reduction and for its maintenance and for the alloying process may be supplied externally or by such means as the gases used in the process.  The heat of the gases leaving the reaction chamber may be utilized by leading the gases around the reaction chamber.  To utilize fully the heat developed during the reaction the walls of the reaction chamber are made of suitable material such as oxides of the metals taking part in the reaction, gold, platinum, iron, or nickel, or the walls may be plated with gold, platinum, &c.
