Filed: 1959-05-13
Abstract: 872,499. Centrifugal liquid/liquid contactor. PODBIELNIAK, W. J. May 13, 1959 [Oct. 21, 1958], No. 16492/59. Class 81 (1). A centrifugal liquid/liquid contactor comprising a rotatable hollow casing and means for admitting and removing the liquid phases is characterized by the provision within the casing of a series of concentrically placed partition walls wherein there are a multiplicity of small size perforations and, additionally, a lesser number of layer openings arranged in a plurality of radially aligned groups so that each group provides an uninterrupted passage through the partition walls from the periphery to the centre of the rotor. There is also provided means for partly or wholly closing the groups of larger holes, e.g. plugs which may be inserted through access parts in the periphery of the rotor. The plugs may be cylindrical or tapered (see Figs. 2 and 3) and may wholly or partly close the openings. Fig. 1 depicts an embodiment of the invention wherein six groups of large openings 32 and the corresponding access ports 34, 35, 36 are shown. In ports 34 are inserted cylindrical plugs 37 which wholly fill the openings; in ports 36 are inserted plugs 38 which partly fill the openings and ports 35 are closed off and the corresponding groups of openings are unobstructed. The provision of the plugs and associated openings provide a means whereby the mixing energy of the system may be varied independently of or in conjunction with variation of the speed of rotation of the extractor. The basic principals of centrifugal liquid/ liquid contactors are briefly discussed in the Specification.

Title: Electro magnetic relays
IPC: H01H51/08
Filed: 1926-07-01
Abstract: 277,449. Ericsson Telephones, Ltd., and Engblom, J. F. T. July 1, 1926. Switches, actuating; electromagnetic interrupters.-In an electro-magnetic relay the local contact springs are operated indirectly from the armature movement through gearing controlled by one or more idle wheels intermittently actuated. As shown, a relay coil C is mounted on a frame F carrying a pivoted armature A which is provided with an extension E carrying a pivoted pawl P. The pawl is adapted to engage a ratchet W loosely mounted on a shaft K and attached to a plate L having one or more sets of two teeth M. An idle wheel I has teeth for engagement with the teeth M and also with the teeth on a. pinion H fixed to one end of the shaft K. Alternate teeth of the wheel I are partly cut away to clear the edge of the plate L. The shaft K carries a cam G for engagement with a lever D adapted to actuate the local contact springs B. The arrangement is such that when the armature A is actuated by the passage of current through the coil C the ratchet W is rotated step-by-step without affecting the wheel I until it has been engaged by the teeth M, whereupon the cam G is given a small rotary movement. The contacts B are closed and remain closed while the lever D is engaged by a projecting portion of the cam G. Contacts Q may be provided directly actuated by the movement of the armature A. In the construction shown in Fig. 3 two trains of mechanism are interposed between the armature and the contact springs J. The cam G, controlling the actuation of the contact springs K is actuated by the ratchet W through the medium of the plate L, idle wheel I, and pinion H, and in turn actuates the cam M controlling the movement of the springs J, by means of the pinion C, idle wheel B, and plate N. A pendulum may be fitted to the armature to assist in the control of the time intervals in the operation of the contact springs, in the case when the device is self-interrupting. Alternatively a copper slug may be provided to steady the movement of the armature.

Filed: 1947-06-27
Abstract: 631,034. Winches. WINTHER, M. P. June 27, 1947, No. 16964. Convention date, July 1, 1946. [Class 78 (v)] [Also in Group XXXIV] A brake for hoisting drums of oil well drawworks and like drilling or boring apparatus combines the high retarding torque of an eddy-current brake at high speeds with that of a mechanical friction brake at low speeds. The shaft 29 of the hoisting drum 27 is driven through gearing 25 and has rotatable with it an eddy current inductor drum 37 and a friction brake drum 35. The friction brake drum is applied by a toggle linkage 43 operated by a handlever 45, which is mechanically coupled to a rheostat arm 51. In position A of handlever 45 both eddy current, and friction brakes are released. As the.handlever 45 is moved to the right, the eddy current brake is energised by the closing of the switch 55 and the resistance 61 is progressively short circuited until at the position C the eddy current brake is fully energised and the brake band 39 of the friction brake begins to expand. At position E both brakes are fully applied. The variable resistance 61 is made part of a circuit supplied by a direct current power source 71, or emergency battery 93, through wire 73, eddy current brake coil 67, contactor 81 and a return wire 79. Contactor 81 and another contactor 77, controlling a circuit in parallel with the rheostat 51, 61 are controlled by relay coils 91 and 87 respectively, the two relay coils being energised by switches 55, 89 and 83, 85 respectively, the latter two switches being normally opened and closed by a spring trigger 65 on the handlever 45. The switch 89 is normally open and is closed by a spring loaded reel 7 and its control cable 9 only when the lower block 15 of the hoisting tackle is raised above the level F. This ensures that by bypassing the rheostat 51, 61, the eddy current brake coil is fully energised at the initial operation of lowering the block 15 on to the top of a length of drill pipe 19 and automatically prevents the block 15 from buffing violently against the block 3 when it is desired to insert a new drill section as rapidly as possible. Trigger lever 65 is used to de-energise the eddy current brake coil 67, during the initial operation described above, until the block 15 has dropped below the level F.
