Title: Drill bit utilization optimizer
IPC: G06F17/11
Filed: 1972-08-08
Abstract: 1396171 Digital computers; well drilling calculations SANTA FE INTERNATIONAL CORP 8 Aug 1972 37004/72 Heading G4A A special purpose digital computer generates data for optimizing the utilization time of a drilling bit for wells, e.g. oil wells. The computer solves the equation where: C = cost in $/ft., B= bit cost in $, D = drilling time in hours, T= bit change round trip time in hours, R = rig cost in $ per hour, F = footage drilled. On starting drilling the cost/ft. is high because of the setting up costs &c. but the cost/ft. decreases as the footage increases. However, after the bit reaches a certain degree of wear, the cost/ft. begins to increase again and, around this point, the bit should be changed. The equation is solved repetitively at intervals and is displayed on a paper tape printer 52 or a light emitting diode display. The optimium solution may be obtained by visual inspection but an audible alarm can be triggered by unit 56 when the cost/ft. starts increasing again.  The computer comprises an integrated MOS circuit arithmetic unit for performing the four rules of arithmetic, an input section 12 and a multiplexer 16. In section 12, stages 20 and 22 receive the total drilling time and the drilling depth from clock and a depth recorder 38 (e.g. conventional borehole depth measuring equipment), and the rig cost, bit cost, and trip time are set manually in stages 24, 26, 28 respectively. Decimal to BCD conversion, a shift register (Fig. 5, not shown), and a keyboard are also mentioned.

The reaction torque exerted during use deflects an elongate component of the assembly 16 and means are provided for measuring this deflection to provide a measure of the torque to which a fastener is tightened. In Fig. 2, a strain gauge 108 measures the angular deflection of elongated ring gear 72 which is fixed to the housing only at the left hand end 74. In the alternative of Fig. 4, the ring gear 190 is rotatable in a bearing 197 of low friction material but rotation thereof due to the torque reaction is resisted by a laterally deflectable beam 200 fastened to the ring gear 190 by fastener 218. The beam, which can be adjustably mounted on casing member 204, also carries a strain gauge 202. Signals from the gauges passing along lines 110, 112 in Fig. 2 or 228, 230 in Fig. 4 may be used to control the air supply to the motor and/or to actuate a dial indicator.

IPC: H02J7/22
Filed: 1956-12-10
Abstract: 824,372. Electromagnetic switches. CIBIE, L. Dec. 10, 1956 [Dec. 22, 1955], No. 37713/56. Class 38 (5). A switching device for limiting the current supplied by a shunt-wound dynamo comprises a U-shaped magnet yoke 2 having a core surrounded by a pair of coils denoted by 1, one coil (the voltage coil) being connected in shunt and the other (the current coil) in series, with the dynamo. A polepiece 4 welded to the upper end of the core has a portion 4b of lesser thickness and a portion 4a of greater thickness underlying, respectively, armatures 6, 5 carried by blade-springs 16, 8. On rise of voltage in the voltage coil the armature 5 is first attracted due to the smaller air-gap 7 and contacts 10, 11 are closed, whereupon current flows through the current coil to reinforce the contact-closing pressure. If the current through the coils increases to a sufficient extent armature 6 is attracted to open current-limiting contacts 18, 19. The armatures are restored by blade springs 12, 21, the latter being associated with a bimetal temperature compensator 22. Spring 8 is also bimetallic for temperature compensation.

Abstract: 888,319. Electrically released switches; protective cut-out arrangements. TEDESCO, J. L. Nov. 9, 1959 [Feb. 20, 1959], No. 37839/59. Class 38 (5). An automatic circuit-closing switch suitable for parallel connection across a circuit liable to interruption comprises a porcelain body 45 closed by a porcelain cap 37 having a metal eyelet 38 in which slides a metal rod 35, the upper end of eyelet 38 clamping down a terminal 40. The toes 49 of a bi-metallic strip 50 secured to the rod 35 by a nut 53, engage a shoulder 48 to space the rod end 54 from an adjustable screw contact 55 against the action of a compression spring S, the terminals 40, 56 being connected to the ends of one " letter " forming part of a neon tube display mounted on a signboard 10, Fig. 1 (not shown). The members 37, 45 clamp between them a washer 60 having three lugs, Fig. 4 (not shown), secured to insulating spacers 62<SP>1</SP> secured in turn to the corresponding lugs of a member 19, Fig. 3 (not shown), mounted on the board 10. The rod 35 is secured to an insulating rod 33 whose upper end protrudes through an aperture in the board 10 and is enclosed by a transparent cover 31 mounted adjacent to the neon tube letter. When the latter is functioning normally the switch is inoperative, but should the tube become opencircuited the voltage across terminals 40, 56 rises to line value to produce an arc between contacts 54, 55 and a subsequent heating of the strip 50, whose legs L move inwards to allow the spring S to close contacts 54, 55 thus shortcircuiting the faulty tube. After replacement, removal of the cover 31 allows the switch to be reset by withdrawal of the rod 33. The switch housing may be modified as in Fig. 6 in which upper and lower caps 76, 65 have lugs engaging channel slots in the body 46<SP>11</SP>, Figs. 7 and 8 (not shown), the cap 65 being enclosed by a metal cover whose edges fit into a groove 66 and a channel 71, and cap 76 being enclosed by a metal cover engaging a shoulder 85 and the rim of an aperture 80, and having three lugs for attachment to spacers 62<SP>1</SP>, Figs. 5 and 9 (not shown). Another upper cap and cap cover arrangement is also described, Figs. 11-13 (not shown). If desired the rods 33, 35 may comprise a single insulating unit and the current path from the eyelet 38 to the contact 55 is through the spring 5, bi-metal 50 and nut 53.

Abstract: 1479563 Anodizing metal throughout its thickness INTERNATIONAL BUSINESS MACHINES CORP 22 Sept 1975 [29 Nov 1974] 38734/75 Heading C7B An electrically conductive layer is formed on a dielectric layer, and a porous, metal, oxide-forming layer is formed on the conductive layer, said porous layer being thicker than the conductive layer and of a different material, and of higher conductivity than the dielectric layer; the porous metal layer is anodized, using the conductive layer as an electrode in the anodizing circuit and under conditions such that the metal is anodized substantially uniformly throughout its thickness, and then the conductive layer is treated to render it non-conductive. The dielectric layer may coat a semi-conductor, e.g. Ge, Si, SiC, Se, a III-V compound such as GaAs, or a doped dielectric; the dielectric may be glass, SiO 2 , GeO 2  Ti oxide or Ta oxide, applied by vapour deposition, sputtering or chemical vapour deposition. The conductive layer may be applied to the dielectric by similar methods, and is preferably a metal, mixture or alloy which acts as a value metal during anodizing, e.g. Mn, Sn, amorphous, or polycrystalline Si, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo or W; the anodizable metal is applied by the above methods or by electrolysis, is at least 5 times as thick as the conductive layer, and preferably contains # 85% Al or Mg, and may be Al alloyed with Mn, Si, Mg, Pb, Bi, Ni, Cr, Zn, Sn or Cu; it is anodized in H 2 SO 4 , H 3 PO 4 , chromic or oxalic acid at 1-20 mA/cm<SP>2</SP>. Parts of the Al may be masked to prevent their anodization, e.g. by standard photo-resist techniques; after anodization the conductive layer may be rendered non-conductive by anodizing at higher potential than for the Al, or using a different solution, or by heating in air, O 2  plasma, or with a substance giving off O 2  at high temperature; the resulting body may be heated at 300-400C for 2-10 hours to release water. Suitable apparatus comprises an anodizing bath having a Pt sheet cathode, a Pt wire connection contacting the conductive layer of the body to be treated, an overflow and pump for recirculating the electrolyte, a heater and thermostat acting on the reserve reservoir for temperature control, and means for agitating the bath, Fig. 6, (not shown).
