Title: Improvements in apparatus for recording data relating to railway tracks
IPC: B61K9/08
Filed: 1938-03-02
Abstract: 504,587. Recording - apparatus ; surveying railway tracks. STEVENS, A. H. (Sperry Products, Inc.) March 2, 1938, No. 6550. [Class 106 (iv)] [Also in Group XX] Data relating to railway track is recorded by mechanism provided in a rail car mounted on front and rear trucks and having an auxiliary intermediate truck which can move relatively to the car body. The auxiliary truck can (I) move laterally to record curvature, (2) tilt with the car to record superelevation, and (3) move vertically to record rail-surface irregularities. The car 10 is mounted on front and rear trucks 11 and the auxiliary truck comprises a frame 16 carrying a closely-fitting axle 18 with flanged wheels 19. Rollers 21, Fig. 5, journalled in a member 24 engage transverse channels 20 secured to the car body, the member 24 having a number of pistons 25 extending into cylinders 26 secured to the frame 16, the pistons being pressed upwards by springs 27. Levers 31, 31<1> are pivoted to the frame 16 and also to tie bars 30, 30<1> connected through spring-loaded shackles 40 and universal joints 36 to the car body. The levers 30, 30<1> are also connected to plungers 44 mounted on the frame 16 and acted upon by springs 42. Recording curvature. Transverse movement of the auxiliary truck is communicated by a link 70, Fig. 6, and rod 72, to a pen P recording on a sheet 50 driven from the wheels of the auxiliary truck. Recording superelevation. A cross-bar 81 secured to the frame of the auxiliary truck is engaged by two rollers 80 on links 82 pivoted to a lever 83 itself pivoted in a block 85 vertically slidable in the car body. An arm 88 secured to the lever 83 engages a vertical slotted member 90 horizontally slidable in the car body and engaged by a pin 94 on an arm 95 of a rod 96 connected by linkage 98, 100 to a pen arm 103 pivoted at 104, and carrying a recording pen P<1>. The point 104 is maintained fixed in space by a gyroscope G. The pen P<1> thus records the tilt of the car caused by superelevation, but the linkage ensures that the pen is not affected by any movement of the auxiliary truck relative to the car due to swaying of the car about a longitudinal axis or by bounce of the car. Recording rail-surface irregularities. Vertical movement of the auxiliary truck relative to the car caused by such irregularities causes movement of the block 85, Fig. 6, this movement being transmitted by levers 111, 114 to a pen arm 116 carrying a pen P<11>.

Title: Method and apparatus for refining metals

Abstract: 1,224,594. Metallurgical converters. CONZINC RIOTINTO OF AUSTRALIA Ltd. 7 Feb., 1969 [16 Feb., 1968], No. 6643/69. Heading F4B. [Also in Division C7] Apparatus for refining metals comprises a circular refining zone into which raw metal and oxygen-containing gas are continuously introduced, an elongated second refining zone and a slag settling zone, the bath being at the same level in the three zones. The second zone is connected at one end to the circular zone and has an outlet at its other end, while the slag separation zone is connected by one end to the circular zone at a location spaced from the junction of the second zone. The apparatus also includes means for introducing oxygen into the bath in the second refining zone, and means such as lances for causing the metal and slag to circulate co-currently in the circular zone but counter-currently in the second zone. As shown, metal tangentially enters circular zone 10 at 13, and gas enters at 34; metal flows to second refining zone 11 having lances 15, 16, 17 while slag passes to settling zone 12 having weir 27 and well 28. Projections 19, which may be of refractory brick or of dolomite and which may be cooled define a third refining zone having lance 18, the flow of slag thereto being retarded by lances 23, 24.

Title: Improvements in and relating to Electro Magnetic Switches.
IPC: H02P1/20
Filed: 1918-04-19
Abstract: 125,732. British Thomson - Houston Co., and Hastings, H. C. April 19, 1918. Systems for continuous-current motors only.-In electro-magnetic switches of the lock-out type for use in starting up electric motors, a spring 18, placed between the switch arm 4 and a lever 9, is stressed by the lock-out magnet and positively holds the switch open until the current in the lock-out magnet falls to a certain value; the stress is then removed by the spring moving the lock-out armature away and the switch closes solely under the influence of the shunt or series closing- coil 7. The lock-out magnet is made in two parts; one, consisting of the series or shunt coil 13 and core 12, is used to stress the spring; the other, consisting of the armature 15 and series coil 17, is used to hold the spring in its stressed condition, the falling current in this coil deciding the point of release of the spring. In a control system, a master controller E has positions for the resistance switches A-D and for the main switch S; this switch is inter-connected with two switches G, H, controlling one pole of the closing- coils 7<a>-7<d>, and the circuit of the stressing-coil 13a; the switch G does not close until after the switch S has closed and the switch H does not open until after the switch S has closed and wiped over its stationary contact. The closing-coils 7<b>-7<d> have their circuits completed in sequence by the switch K of the preceding contactor. When, for example, the master controller is moved to position c, the switches A, B, and C may close; when the switch A closes, the stressing-coil 13b of the switch B is short-circuited, the switch being held open by coil 17b alone; the same action takes place with the other switches; the circuit of the stressing-coil 13a is broken at the switch H. In another arrangement using series stressing coils, a simple switch replaces the controller E and closes the circuit of the coil 13a, which is a shunt coil, and the circuit of the main switch S, which is interconnected with a switch H for opening the circuit of the coil 13<a>; each closing- coil is energized by the closing of the previous contactor.

IPC: B66B1/50
Filed: 1933-03-07
Abstract: 409,487. Lifts. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.-(Lassen, E. U. ; North 12th Street, Milwaukee, Wisconsin, U.S.A.) March 7, 1933, No. 6900. [Class 78 (ii).] Electric plant.-An automatic floor-levelling device includes transformer apparatus whose energization varies with variations in the position of the cage, and which takes over the control of the operation of the cage when the normal control means are in inoperative position. An E-shaped transformer core 10 having on its outer legs windings 10<a>, 10<b>, and on its central log windings 10<c>, 10<d> is mounted on the cage 9. The windings 10a, 10<b> are connected in series across the lines L <1>, L<2>, and are wound in such a manner that the fluxes, which they induce when the core 10 is opposite an armature 11 provided at each floor, are in the same direction and normally produce no resultant flux through the central leg. If the armature occupies the position shown in dotted lines, a flux will pass through the lower and central legs which induces a voltage in the coils 10<c>, 10<d> which are wound in opposition relatively to each other and connected to the control grids 6<c>, 7<c> of electronic discharge apparatus 6, 7. When the armature is nearer to the upper than to the lower leg, the induced voltage is opposed to the voltage in the former case. As the cage approaches a floor, the attendant moves the control lever 8<a> to the central position which disconnects the motor 1 from the line and applies the brake B. If the cage stops in the position shown, a voltage is induced in the winding 10<c> of such polarity that during the half cycle when the anode of the tube 6 is positive with respect to the cathode, the grid also is positive and the tube 6 becomes conducting thereby energizing the relay 4. Circuit connections for the motor are thus established, and the cage moves down until the core 10 is located centrally with respect to the armature 11. In this position no voltage is induced in the winding 10<c>, and no current flow can be established during the positive half cycle through the tube 6. Accordingly the relay 4 is de-energized and the motor disconnected from the line. If the cage comes to rest in such a position that the armature 11 bridges the gap between the upper and central legs, then the tube 7 becomes conducting, and the relay 5 is energized to restart the motor.
