Title: Improvements in or relating to the Rectification of Alternating Currents of Electricity.
Inventor: POLLOCK SAMUEL ALEXANDER
IPC: H02M7/36
Filed: 1917-09-19
Abstract: 119,081. Pollock, S. A. Sept. 19, 1917. Commutator switching-arrangements. - Alternating currents are rectified by means of a relay, with a polarized armature moving from one position to the other as the flux reverses, the relay having a winding carrying the supply voltage and other windings carrying the whole or part of the load current. The primary of the transformer P is connected to the alternating current supply, and the halves of the secondary winding are used alternately to supply the rectified load circuit which in this case consists of a battery O. The rectifying relay A has an oscillating tongue c<1> polarized by an electro-magnet or by a permanent magnet p<1>. A voltage winding d is connected in series with a condenser k across the transformer secondary, and the condenser capacity is adjusted so that the reversal of motion of the tongue c' occurs when the current through the contact is at or near its zero value. Current coils e<1>, c<2> also are provided on the relay, and are connected alternately in cireuit as the relay operates. A cut-off relay B is connected in the system and has operating coils h, i, j. The coils j are connected with an adjustable resistance n across the battery 0, the coils i are connected in series with the coils e<1>, e<2> of the rectifying relay, and the coils h and polarized tongue g carry the rectified current which passes through the load O. The coils i, j act differentially and, whenever the voltage on half the transformer winding exceeds the battery voltage, the tongue g is moved to the left to close the charging circuit. The whole of the secondary may be used for supplying the rectified current, and a second polarized tongue is then used on the rectifying relay. Where large currents and high voltages are employed, a number of polarized tongues may be used, and they mav be arranged in various combinations in series and parallel. In high-tension installations, the transformer windings are divided into sections which are connected in series to the circuit by numbers of the polarized tongues; and low-tension windings are placed on the transformers for connexion to the voltage windings on the relays. The construction of the relays is shown in Fig. 8. Three cores 1, 5, 6 carry separately the relay windings causing the tongues c, t to oscillate between the contacts b<1>, b<2>, t<1>, t<2> which are adjustably mounted on metal screws 8. 7, 9, 10 threaded in insulated metal plates. The cores are provided with polar extensions 19, 20, 21, 22. The arrangement of relays may be used for the rectification of three-phase currents. In this case, a transformer as shown in Fig. 16 may be used to ensure that power is obtained simultaneously from the three primary phases. The supply leads are connected to the primary windings P<4>, P<5>, P<6>; the secondary windings are interconnected and the terminals are connected to the windings of the separate transformers of the rectifying-apparatus.

Abstract: 165,298. Sandycroft, Ltd., and Bullock, W. May 18, 1920. Crushers with vibrating jaws.-In a crushing- machine in which the movable jaw is mounted on a pivot at its lower end, the eccentric shaft for operating the pitman that operates the toggles is arranged above the toggle-plates, which are spread out by the upward movement of the pitman so that the thrust is transmitted approximately in a direction tangential to the arc of movement of the line on the movable jaw where the forward toggle-plate bears upon it, whilst the tension rod serving to open the movable jaw under spring action passes through a slot in the pitman. As shown, the jaws 1, 9 are made so that the transverse width of the gap between them widens from the top to the bottom so that the ore &c. can spread out laterally as the gap narrows down. The movable jaw 1 carried on a pivot 10 at its lower end has upwardly-projecting lugs 11 carrying the pivot of the tension rod 2 which passes through the slot 18 in the pitman 8. The pitman 8 has long faces 19 at its lower end provided with bearing-surfaces 20 for the ends of the toggle-plates 4, 5. The forward toggle plate 4 is preferably formed in two sections connected together by rivets 29 so as to form a safety-device. The rear stay 12 of the frame, against which the rear toggle 5 bears, is disposed at a lower level than the top of the jaw 1 so that the plates 4, 5 extend in an upward direction toward the jaw 1. The pitman may have strengthening ribs or flanges 23 on its faces, and preferably widens from its upper to its lower end. Instead of a single wide pitman 8, a pair of pitmans and two pairs of toggles may be used.

Inventor: BLOXAM ARTHUR GEORGE
IPC: F41G5/00
Filed: 1918-08-23
Abstract: 123,279. Bloxam, A. G., (Russische Akt.- Ges. L. M. Ericsson & Co.). Aug. 23, 1918. Speed indicators operating by sighting aerial objects.-Relates to apparatus for indicating the lateral and vertical deflections to be applied to gun sights to correct for the speed of target, the drift of the projectile, and the results of spotting. According to the invention, the apparatus comprises a shaft rotating at constant speed, vertical and horizontal shafts driven by the first shaft through variable-speed transmission gear, a telescope carried by either the vertical or horizontal shaft and kept sighted on the target, a bar moved in accordance with the adjustment of the transmission gear and also in accordance with the range, and a pointer operated by the bar and indicating the product of the angular speed of the target and the time of flight of the projectile on a scale which may be movable to correct for drift and the result of the spotting. In the apparatus shown, the telescope 8 is carried either by a vertical shaft 5 or by an horizontal shaft 7, both of which are driven through variable speed transmission gear 4, such as that described in Specification 130,163, [Class 80 (ii), Gearing, Variable-speed &c.], from a shaft 2 rotating at constant speed. The ratio of transmission is controlled by a shaft 9 in such a way that the angular speed of the shaft 5 or 7 is proportional to the angle through which the shaft 9 has been rotated. This angular speed is converted into the product of the angular speed of the target and the time of flight of the projectile by calculating-mechanism comprising a slotted bar 13 pivoted at one end to a nut 10, which is actuated by the shaft 9, and engaging by means of its slot 13<1> with studs on a nut 18 and a slide 15. The nut 18 is traversed according to the range along a guide way 19 perpendicular to the shaft 9 at the mean position of the nut 10, and the slide 15. moves parallel to the shaft 9 and indicates, by means of its index 15<1>, the desired correction on a scale 21. The scale 21 is movable longitudinally by means of a screw 23 and milled heads 27, 28 to apply the spotting and drift corrections which are indicated against indexes 25, 26 on a fixed scale 24. The total correction is then read on the scale 21 against the index 15<1>.

Title: Improvements in or relating to an oscillatory system for a timing device
IPC: G04C3/06
Filed: 1969-03-17
Abstract: 1,210,762. Electric clocks. KIENZLE UHRENFABRIKEN G.m.b.H. March 17, 1969 [March 20, 1968], No. 13824/69. Heading G3T. [Also in Division H2] An oscillatory system for a timing device such as a clock comprises a spring restrained balance which consists of or carries a magnet 2 having diametrically opposed poles, two control coils 3, 5 connected in series in the input circuit of a transistor and drive coils 9, 10 in the output circuit of the transistor. Each control coil has a first portion 4, 6 in which a potential is induced by a pole of the magnet when the balance passes through its datum position and a second portion 7, 8 in which the potentials induced by a pole of the magnet when the balancepassesthroughaposition at 90 degrees to its datum position are of opposite sign and therefore cancel each other. Since the control coils are connected and wound so that the direction of the induced current is the same in both coils, the potentials induced in the portions 4, 6 at the datum position of the balance are additive to provide a negative pulse whilst those induced in the portions 4, 6 at a balance position 180 degrees from the datum position are additive to provide a positive pulse. Only the negative pulse triggers the transistor so that a single driving pulse is produced each complete oscillation. Instead of the single magnet, two parallel bar magnets may be mounted on the balance staff, one on each side of the coils.

Title: Process for the manufacture of unsaturated gaseous aliphatic hydrocarbons
IPC: C10G9/36
Filed: 1961-04-17
Abstract: Unsaturated gaseous aliphatic hydrocarbons such as ethylene and acetylene are obtained by the pyrolysis of a liquid or gaseous hydrocarbon at above 700 DEG C. by contact with a hot combustion gas for 10-4 to 10-1 second followed by chilling wherein the combustion gas is obtained by adding a hydrocarbon to a first hot combustion gas whereby the hydrocarbon is vaporized and cracked and burning the product in the presence of an oxygen containing gas to obtain a second combustion gas used in the pyrolysis.  The first combustion gas having a temperature above 1500 DEG C. is obtained by burning hydrogen carbon monoxide and/or methane, e.g. obtained from the reaction products.  The hydrocarbon added at this stage may be a high boiling hydrocarbon and may include tarry residues; the mixture is maintained at above 800 DEG C. for 10-4 to 10-1 second before adding oxygen and burning.  Steam may be added to control the temperature. The hydrocarbon to be pyrolysed may be preheated to 25 DEG -400 DEG C. In a preferred process, both hydrocarbons are obtained by distillation of a single crude or purified mineral oil, the overhead being pyrolysed and the residue being burned.
