Title: Process for the surface improvement of metals and alloys
IPC: C23C10/28
Filed: 1937-12-14
Abstract: 507,341. Coating metals; alloys. INSTITUT FUR PHYSlKALISCHE CHEMIE DER METALLE AM KAISER-WILHELMINSTITUT FUR METALLFORSCHUNG Dec. 14, 1937, No. 34633. Convention date, Dec. 14, 1936. [Classes 72, 82 (i), and 82 (ii)] In order to avoid the formation of brittle intermetallic compounds when introducing a metal B into the surface of a metal A by cementation, there is used instead of the metal B itself an alloy of the metal A with the metal B which corresponds approximately, and preferably exactly, with the composition of that intermetallic compound which in accordance with the phase diagram of the system A-B is coexistent as a separate phase with the metal A or with the solid solution of A with B, if any, rich in A. Instead of the alloy a mixture of the components in the same proportions may be used. If it is desired to introduce into A two or more metals B, B1, B2, &c., the composition of the cementation powder will depend on whether the metals B1, B2, &c. do or do not form compounds with A. If the metal A contains alloying constituents A1, A2, &c, the cementation material may or may not contain these metals according to whether it is or is not desired to prevent outward diffusion of these constituents. To diffuse magnesium into aluminium the aluminium may be heated at 445‹C. in a pulverized alloy corresponding to the composition Al3Mg2, i.e. an alloy containing about 38 per cent of magnesium ; if a thicker layer is desired an alloy with a slightly greater magnesium content, e.g. 42 per cent, may be used, or if a particularly gradual transition is desired the percentage of magnesium may be reduced slightly below 38 per cent. To diffuse aluminium into magnesium, the latter is embedded in a powdered magnesium-aluminium alloy containing about 58 per cent of magnesium and heated at a temperature just below the eutectic temperature of 436‹ C. Beryllium may be introduced into copper by heating the copper in vacuo at 830‹ C. in a finely ground alloy of 90 per cent of copper and 10 per cent of beryllium, and bismuth may be introduced into magnesium by embedding the magnesium in a powder consisting of a mixture of about 85 per cent of magnesium and 15 per cent of bismuth (corresponding to the compound Mg3Bi2) and heating at 526‹ C. The Specification as open to inspection under Sect. 91 describes also the impregnation of copper with silicon by heating in vacuo at 770‹ C. in a powder consisting of 87À2 parts by weight of copper and 12À8 parts of silicon (corresponding to the compound Cu3Si). This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to change-speed and clutch operating mechanisms for motor vehicles
IPC: F16H61/02
Filed: 1928-11-24
Abstract: 301,315. Brunet, G. Nov. 26, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Controlling different functions by same handle or lever; pneumatic transmission.-Upon the gear lever of a motor-vehicle is mounted the control for a power device to disconnect the engine clutch during speed changing. This clutch control may also be used to effect double declutching and also to accelerate the engine when changing to a lower speed. The gear lever a, Figs. 1, 2 and 4, has a ball end b with auxiliary lever e pivoted about a diameter of the ball and secured by an arm e<2> to a cylindrical valve d. A spring j, Fig..1, normally holds lever e in position shown with valve d in position shown in Figs. 2 and 6 connecting duct g<1> to the atmosphere. The clutchoperating motor is a cylinder, not shown, to which duct g<1> connects. With that cylinder open to air, the engine clutch is engaged. To effect a change of speed, the knob b is grasped and lever e turned to position shown in Fig. 4. This turns valve d to connect duct g<1> to a duct h<1> connected to suction of the engine and the declutching cylinder operates. The lever a is moved to change gear and lever e released to reclutch. In order to effect double declutching in changing down, the duct g<1> may be momentarily opened to the atmosphere by pressing a button m, Fig. 4, which opens to the atmosphere a duct l connected to duct g<1> at k. The engine may be momentarily accelerated by actuating the usual pedal. In the arrangement shown in Fig. 10, the engine control is embodied in the knob b. The middle chamber q of slide valve s is inoperatively connected to suction in the hollow valve cylinder d. Port x leading to a cylinder acting on the throttle is open to the atmosphere through port y. When thumb-piece t is thrust inwards against spring u, port x is connected to suction and the engine is accelerated. An arrangement is indicated in which the rotary valve d is replaced by another slide valve. The distributing valve d may be on the chassis p as shown in Fig. 9 and only the lever e<1> for turning it to declutch, and the doubledeclutching button m, may be on or adjacent to the knob b. An electric switch may replace the air valve described.

Abstract: 395,739. Separating solid materials. MEUNIER, F. J., 3, Villa Blaise Pascal, Neuilly, Seine, France. Dec. 15, 1931, No. 34713. [Class 117.] In apparatus for separating materials of different density such as raw coal mixtures, of the type comprising a jigging table divided longitudinally into sections along which the materials are fed and through which air is blown from beneath to cause the materials to stratify, provision is made at the end of each section for discharging part of the lower layer of dense material through a number of spaced transverse apertures, and shallow tapering guide channels leading to the openings are formed on the forward part of each section. A number of spaced transverse skimmers, disposed above the table and between the apertures may simultaneously remove part of the upper layer of light material. As shown in Figs. 2, 5 and 6, the table sections 12 are connected by solid plates 13, provided with transverse slots at 40 coacting with a cut away cylinder 22 to form adjustable discharge openings. Leading to the openings are tapering channels 21 formed by angle plates 20 of less depth than the thickness of material. The heavy material passing through the slots 40 is discharged by channels 14. Disposed above the table between the apertures is a transverse series of skimmers 25 by which the topmost layer is deflected to discharge through the passages 15. The last section of the table is preferably tapered and provided with pivoted adjustable plates 32 for controlling the size of the discharge openings for the lower layer at this stage. In the form shown the plates are operated by a right- and left-handed screw 33. In a modification a wedge-shaped plate longitudinally movable may be utilized to form two guide channels with the sides of the section. Fig. 7 (not shown). The table is mounted on a stationary air chamber and connected thereto in an air-tight manner, the space under each section being subdivided into compartments each with an independent air control valve. A preliminary sifting screen 10 may be associated with the feed end of the table and a byepass from the air-chamber provided to allow air from the chamber to be blown through the screen for cleaning purposes. The actuating mechanism consists of an eccentric rod 7 connected to the table through cushioning springs 8 and the table supporting brackets 2 are disposed between buffer springs 3.

Title: Improvements in or relating to remote control apparatus
IPC: H04M11/04
Filed: 1930-11-20
Abstract: 367,433. Electric signalling systems. GRASEBY, R. C., Kingston By-Pass Road, New Malden, Surrey. Nov. 20, 1930, No. 34955. [Class 40 (i).] The opening or closing of a circuit is determined by switch means which are controlled by two electromagnets adapted to be energized by currents of different frequencies transmitted over common supply wires, one of the armatures operating to change the position of the switch means, and the other armature operating to release catch means whereby the former position of the switch means is restored. Electromagnets 2, 18, Fig. 2, adapted to be energized respectively by currents of different frequencies, and a condenser 26 are connected, as shown, to supply wires 31. The armature 3, Fig. 1, of the electromagnet 2 forms part of a bell crank, the arm 5 of which contains a block 12 adapted to close switch contacts 10, 11 when the magnet is energized. The contacts 10, 11 control the opening or closing of a signalling circuit. The armature of the magnet 18 is carried by a bellcrank lever 20, the arm 21 of which is formed with a notch 24 for engagement with a projection 17 on the armature 3. The arrangement is such that when the magnet 2 is energized the armature 3 is held in its attracted position by the engagement of the notch 24 and projection 17, the armature 3 being released and consequently the switch contacts 10, 11 being opened when the magnet 18 is energized. The catch means 17, 24 may be replaced by catch means on the spring 8 adapted to be disengaged by the energization of the magnet 18. The arrangement may be modified so that the armature 3, when attracted, is adapted to open the switch contacts, which are closed when the catch means is released. The apparatus described may be used in police call boxes connected by telephone wires to a police station. A telephone bell at each box is in series with the relay apparatus. The electromagnet 2 is energized by current of the usual frequency employed for ringing the telephone bell. Switch contacts 10, 11 at each box close to light a signal lamp in each box. On disconnecting the ringing current the lamps remain alight. When the call is answered from one box the operator at the control station sends over the wires a current of different frequency from that of the ringing current, whereby the electromagnet 18 is energized and the signal lamps are extinguished.
