Title: Improvements in methods and apparatus for cutting electrically conductive materials
Inventor: RUDORFF DAGOBERT WILLIAM ALFRE
IPC: B23H5/00
Filed: 1952-04-30
Abstract: 780,242. Removing metal by electro-erosion. SPARCATRON, Ltd. May 19, 1953 [April 30, 1952], No. 10872/52. Addition to 637,872. Class 83 (4). In apparatus for cutting electrically conductive materials comprising a cutter electrode which is maintained in close relation to the workpiece forming the other electrode, a current supply source is included so that electric discharges are continuously produced between the cutter and workpiece which alternate between a spark discharge for evaporating material and an arc discharge for preheating the material and means are provided for flowing fluid through the cutting zone to remove disintegrated material and to cool the zone. The workpiece and electrode may be kept in relative motion and rubbing contact may be maintained, the contact pressure exerted being less than the vapour pressure exerted by the evaporation so that the cutter floats on the vapour. A capacitor may be connected between the cutter and the work to discharge intermittently, each discharge commencing with a spark and terminating.in an arc. Adjustable capacitance may be provided. The circuit is preferably made non- oscillatory by being critically damped or overdamped when the number of discharge periods may be above 5000/sec. The change-over of spark discharge to arc discharge may be caused by impressing an additional intermittent and/or cyclically variable electric motoric force upon the circuit of the cutter and workpiece. The discharges and intervals may be obtained by using a D.C. source and interrupting or diminishing the flow of current during the intervals by including an interrupting device, e.g. a thermionic valve in the circuit. A pilot spark may be used to trigger the spark discharge. As an alternative to the pilot spark the gap between the cutter and the work may be reduced by a vibrating device. The cutter may be made the anode during arcing and the cathode during sparking. An A.C. supply may be provided for sparking and arcing which may be weakened to produce the intervals. D.C. supply is preferable and electronic valve gear is used to effect polarity reversal.

Abstract: 163,031. Bosch, Akt.-Ges., R. May 3, 1920, [Convention date]. Brush-holders; casings; terminals and accessories, arrangement on machine. - A voltage regulator g, Figs. 1 and 2, and an electromagnetic cut-in switch g<1> for a vehicle-lighting or other dynamo are joined together both mechanically and electrically at the ends by means of two conducting bars h, i so that they form a unit which can be readily mounted upon or removed from the dynamo casing c. The parts g, g<1> are fixed to the casing c by means of recessed clamping members m, o which are forced together to grip the parts g, g<1> by means of a screw p; the lower member m is secured to the dynamo casing by bolts n. The leads from the regulator and the switch are joined to the brush-holders e, e<1> by means of screws f, f<1>; the brush-holders are attached to inclined sides of the casing c. The rear bar i is formed with a lug k which is connected electrically to the top part a of the casing by means of a screw l. The circuit-connections are shown in Fig. 3. The moving cores 17, 18 of both the cut-in switch and the regulator serve as switch contacts co-operating at their ends with stationary contacts 13, 14 and 15, 16 respectively. The voltage is regulated by connecting periodicallv a resistance t in series with the dynamo exciting coils r; at excess speeds, contacts are made which short-circuit the coils r.

Patent GB-1123122-A (GB)
Title: Pumping apparatus of the flexible tube type and method of operation thereof
IPC: G01N35/08
Filed: 1966-03-15
Abstract: 1,123,122. Rotary pumps. TECHNICON INSTRUMENTS CORP. March 15, 1966 April 5, 1965], No. 11214/66. Heading F1F. [Also in Division B8] In a rotary pump for use in chemical analysis, a plurality of flexible tubes 64 are periodically and sequentially constricted by rollers 72 attached to a pair of driven endless chains 68 to effect a peristaltic pumping action, a portion of each of which tubes is supported beneath the rollers by a spring-loaded flat table or platen (54), Fig. 5 (not shown), one of the tubes 64A being filled with a relatively inert fluid, e.g. air, and connected at its outlet end to that of an adjacent tube 64B containing a reagent fluid, and the flow of inert fluid from the tube 64A being periodically interrupted by a pin 94 whereby the reagent fluid entering tube 106 is segmented. The pin 94 is carried by one end of an arm 92 pivotally supported by a bearing 93 and having a cam surface 100 at its end remote from the pin, said surface being periodically engaged by an extension 102 of a bearing pin for each roller. The end of the arm 92 carrying the pin is biased downwardly by a tension spring 98 so that a portion of the tube 64A lying on a block 86 is normally constricted by the pin. Thus, quantities of inert fluid enter the tube 106 in phase with the peristaltic pumping action and the consequent segmentation of the reagent fluid in the tube 106 effects proper proportioning of the reagent fluid relative to a sample fluid flowing in a tube 64C when these fluids are mixed in an outlet tube 110. This arrangement provides compensation for the fluctuations in the rates of flow of fluids in the tubes 64B, 64C and allows these tubes to have different diameters. Segmentation of the sample fluid may be effected in the upstream portion of a flexible tube (152B), Fig. 10 (not shown), by periodically injecting an inert fluid e.g. air, into the inlet end (160) of said tube within a container (162) for said fluid, the inert fluid being supplied through a flexible tube (152A) controlled by a pin (94') in a manner similar to that shown. The pins 94, (94') and the parts associated therewith may be replaced by a solenoid operated valve (not shown in the drawings), which is actuated by the rollers. Alternatively, a sample fluid and a reagent fluid flowing in flexible tubes (204A, 204B), Fig. 9 (not shown), due to the action of rollers (202), are mixed when they enter a tube (208) whose outlet end lies in a tube (212) connected to a mixing coil (214), segmentation of the mixture of fluids being effected by an inert fluid e.g. air, entering the tube (212) adjacent the outlet end of the tube (208) from a flexible tube (204C), through a tube (210) made of a material, e.g. P.T.F.E., having a relatively low surface-tension. The tube (212) is made of a material, e.g. glass, having a relatively high surface-tension whereby a quantity of the inert fluid is held in the tube (210) until the pressure developed in the tube (204C) by the rollers is sufficient to drive it into the tube (212).

Abstract: 473,081. Centrifugal gas - cleaners. BERRISFORD ENGINEERING CO., Ltd., and ALLEN, R. H. April 24, 1936, No. 11737. [Class 23] Hot air or other gas containing suspended solid particles is caused to whirl ; a small portion with the suspended matter is tapped from the periphery, passed to a separate chamber and cooled, and the suspended matter is then extracted. The volute casing 1 has a tangential inlet 2 and a telescopic clean gas outlet 4 with a flared skirt 5. Near the lower end of the conical part 7 of this separator is placed a conical saucer 8 with a central aperture 10, and arranged so that a gap 9 is left between its periphery and the cone 7. A volute casing 13 with a tangential outlet is fixed below the cone 7 and the annular passage between them contains sloping blades 12. A cool gas inlet 15 at the centre of the volute 13 opens beneath a conical cowl 16. The gas whirls in the main body of the separator, and the peripheral portion with the dust passes through the gap 9 and then between the vanes 12, which maintain the whirl, to the volute 13. Here it is cooled by the gas from the inlet 15 and the dust is thrown outwards and carried away by the tangential discharge to another separator such as a cyclone separator. Vanes 17 are provided so that the cool gas from the inlet 15 is given a whirling movement similar to that of the gas from the cone 7. The conical cowl 16 and the saucer 8 are adjustable in height, and the cyclone separator to which the dust-laden gas is led from the volute 13 may be combined with the rest of the apparatus to form a single co-axial unit. A small quantity of water can be injected into the dustladen portion of the gas.
