Title: Improvements in or relating to indirectly heated cathodes
IPC: H01J1/22
Filed: 1960-10-17
Abstract: 885,629. Indirectly-heated cathodes. EGYESULT IZZOLAMPA ES VILLAMOSSAGI RT. Oct. 17, 1960 [Oct. 15, 1959], No. 35531/60. Class 39(3) The heater element of an indirectly-heated cathode is made of tungsten, molybdenum or tantalum wire, containing at least 0À5% by weight of a refractory oxide other than the oxide of the wire metal, e.g. an oxide of Th, Zr, Hf, Al or Be, and being only in a primarily recrystallized, i.e. not fully recrystallized, state. It has been found that such wires, which during manufacture and use are not heated to temperatures above 1,600‹C., a temperature substantially below that required for secondary recrystallization, have great mechanical strength and may be used with or without an insulating coating, e.g. of alumina. A suitable heater element may be of tungsten containing 0À65% by weight of thorium oxide and may be made by mixing pure tungsten oxide with 0À75% by weight of thorium oxide and heating. Specification 861,383 is referred to.

Title: Improvements relating to slicing machines
IPC: B26D7/32
Filed: 1933-12-19
Abstract: 423,893. Slicing - machines. FITZPATRICK, H. D., 94, Hope Street, Glasgow.- (Maatschappij Van Berkel's Patent Naamlooze Vennootschap ; 33, Boezemsingel, Rotterdam, Holland) Dec. 19, 1933, No. 35688. [Class 28 (ii)] A slicing-machine has a slice-stacking mechanism including a conveyer which is driven from a reciprocating part of the machine by a connection comprising two alternately operable drives, each including a one-way clutch the driving-element of which is arranged to rotate in a direction opposite to that of the other driving-element, both driving-elements being subjected to repeated reversals of directions. As shown, the drive is effected by a rack 29 on the reciprocating carriage 2,which gears with a gear wheel 28 meshed with a gear wheel 34. The wheels 28, 34 are constructed as one-way clutches, e.g. of the wedging roller type, the shafts 24, 25 driven by the clutches carrying sprocket wheels 22, 23 over which the chain 21 driving the sprocket 20, is passed. The sprocket 20 drives the shaft 14 carrying the arcuate conveyer 13, the prongs 16 thereof co-operating with the guide 17 and the discharge fly 18 in the usual manner. The conveyer performs a complete revolution for each to-and-fro movement of the carriage, and the drive components may be so dimensioned that the linear speed of the prongs 16 is equal to that of the carriage in both of its directions, or, alternatively, the speed of the prongs during the return stroke of the carriage may be different from the carriage speed.

Title: Improvements in and relating to a digging process and a grab bucket for use in said process
IPC: E21B11/04
Filed: 1962-09-19
Abstract: 995,264. Grab excavators. S. A. FONDEDILS (S.A.F.) S.p.A. Sept. 19, 1962, [Sept. 20, 1961], No. 35710/62. Heading E1F. [Also in Division B8] Associated with a grab bucket is means by which an impact force or forces can be applied to the jaws of the bucket to cause initial penetration of the digging edges on the jaws into material which is to be subsequently gathered into the grab bucket as the jaws thereof close together. The means for creating the forces may be gravity, fluid or electrically actuated. The gravity actuated means shown comprises a heavy weight 21 secured to the hoist rope of the bucket and having a limited sliding movement within a frame 10 to which the bucket jaws are pivotally connected through links 12. The jaws are also pivoted at 16 to a block 17, that when the hoist rope 25 is wound in, is raised in the frame 10 by a chain 20 by which the block 17 is attached to the weight 21. If no tension is exerted on the chain the block 17 moves to the lowest possible position as determined by abutments in the frame to cause the jaws to open. Removal of tension on the cable 25 allows the weight to fall and strike abutments 23 in the frame 10 through which a blow is thus transmitted to the digging edges 15 of the jaws. To allow of opening of the jaws 14 to allow of discharge of the contents of the bucket the frame is at the desired discharge point held in space whilst the rope 25 is slackened.

Abstract: 318,064. Siemens - Schuckertwerke Akt.-Ges., Richter, H., and Dieterlen, M. Dec. 5, 1928. Dynamos, regulating; exciting; pole-pieces.-A cross-field continuouscurrent machine, such as is used for arc welding, is adapted for regulation of its cross-field by providing in addition to the main field coils additional coils placed on auxiliary iron circuits outside the main coils and so connected that their magnetizing force opposes the flux which the ma.in coils tend to establish in the auxiliary magnetic paths, the relative current strengths in the main and additional coils being variable bv hand control. In the form shown in Fig. 1, the main coils E', E<2> are seriesconnected with an arc load 15 and set up the cross-flux bv the short-circuit currents in the brushes 3, 4. The poles 8<b>, 9<b> are connected to the yoke 10 by auxiliary magnetic members h', h<2> and h<3>, h<4> which carry additional windings e<1>, e<2> and e<3>, e<4> connected in series with one another and in parallel with the main coils and having a regulating resistance 21 in their circuit. The connections are such that, as shown by the arrows, the coils e<1> - - e<4> magnetically oppose the main coils in the local flux circuits h<1>, 10, h<2> and h<3>, 10, h'. Adjustment of the resistance enables the cross flux to be controlled and the load characteristic of the machine to be correspondingly varied. The coils e<1> - - e' may be connected in shunt instead of in series with the armature, and the members h<1> - - h<4> may alternatively be joined by separate yokes instead of by portions of the main machine yoke. In the form shown in Fig. 3, the additional cores h', h<9>, and h<8>, h<10> are placed between the yoke 10 and main pole-pieces 8<b>, 9<b> outside the main pole-legs 8<a>, 9<a> and the auxiliary coils e', e<8> include the three magnetic limbs under each pole-shoe. In this form, the cores h<7>, h<9> are formed as parts of the laminae comprising the main poles as shown in Fig. 5. The laminae are bolted to the yoke 10 with intervening magnetic or non-magnetic plates 33, the thickness of which affords a means for controlling the size of the air-gap of the machine. In place of using resistance for controlling the auxiliary excitation, this may be done by cutting out turns.

Abstract: 1440521 Data processing SCHLUMBERGER INLAND SERVICES Inc 30 July 1973 [31 July 1972] 36104/73 Heading G4A A machine implemented method of aligning first and second sets of separately derived well logging data, which may be subject to relative depth displacement, includes the steps of deriving normalized correlation functions corresponding to a pluraity of displacements between a selected group of first data and selected groups of second data, repeating for different groups of first data to obtain overlapping normalized correlation functions, and combining at least some of the overlapping functions to obtain an improved correlation function. In the preferred method, the overlapping correlation functions are averaged and the displacement between the two sets of data is determined and is used to align the data with respect to depth. Minimum and maximum values of each correlation function may be identified and selectively scaled so as to be accentuated relative to the remaining values of the function, values below a predetermined level, corresponding to reliable correlation between the two logs, being excluded. Various procedures are described for improving the reliability of the results and for interpolating displacement values between displacement values deemed to be reliable.
