Title: Rotary bit for hydraulically drilling holes into underground formations
IPC: B23K9/02
Filed: 1973-03-05
Abstract: 1469524 Rotary bits SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 5 June 1974 [5 March 1973] 10530/73 Heading E1F A rotary hydraulic jetting bit has nozzles whose outlets are centred on circles concentric to the central axis of the bit, the distance between the intersections of adjoining circles with a plane including the central axis being not greater than <SP>3</SP>/ 2  (d 1 +d 2 ), where d 1 , d 2  are the diameters of the nozzle outlets on the respective circles. The axis of each nozzle intersects the central axis of the bit or a line parallel thereto at an angle other than 90‹ and lies in or is tangential to an imaginary cone centred on the axis of the bit, each such cone having its apex above the end of the bit containing the nozzles and the apex angles of adjoining cones not differing by more than 14‹, the largest apex angle being over 90‹. In the embodiment shown, a single row of aligned nozzles is provided, and the nozzle axes intersect the central axis at a common point. The end of the bit through which the nozzles extend may alternatively have a flat central portion and radiused ends, or it may be part-spherical, in which latter case the nozzles may be distributed over the part-spherical end rather than being arranged in a row. In another embodiment, the bit has lands in the surface of which diamonds are embedded and the nozzles open into water channels between the lands. In each case, the nozzle axes need not necessarily meet at a common point on the bit axis. The nozzles may be wear resistant inserts and preferably have an outlet diameter of 1.5-4.0 mm. Nozzles of various size may be incorporated in a single bit and the spacing may be non- uniform. Each nozzle typically has a cone angle of 10‹ and its inlet end is radiused, the radius being equal to the diameter d of the nozzle outlet. The nozzle length is typically equal to 3.1 d.

Title: Improvements in or relating to telephone or like systems and to hunting switches therefor
IPC: H04Q3/00
Filed: 1935-06-21
Abstract: 458,845. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., WRIGHT, E. P. G., and HARTLEY, G. C., 63, Aldwych, London. June 21, 1935, No. 10550/36. Divided out of 458,838. [Class 40 (iv)] In a non-numerical or numerical switch which gives access to a group or groups of junctions and which waits at the beginning of a group if no idle junction is available and sends a signal to the operator setting up the connection, a different signal is sent when a junction becomes available but hunting is delayed until a return signal is received from the operator. Specification 458,838 is referred to. Non-numerical switch, Fig. 1. The switch is seized from a group selector and line relay A connects relay P to a wiper of which the home terminal is connected to battery as long as there is an idle junction. Operation of P disconnects C and connects up L which completes the usual stepping and test circuits. If P fails to operate, C energizes, applying a flash signal FL to wire d and connecting resistance relay HR in series with P. When a junction becomes available, only HR operates and applies a rapid flicker signal to wire d over the lower winding of C and interrupted battery to the upper winding, C thus being held. The operator initiates hunting by opening wire d, whereupon C falls back and disconnects HR to allow operation of P. If two operators initiate hunting simultaneously, only one relay P operates, and in the other switch C re-energizes and applies the original flash signal. Group selector, Fig. 2. This is set by one or two digits according as the wanted group occupies a whole level or part of a level. Dialling relay C (not shown), controls CC, and on the relapse of C at the end of the numerical setting, relay P is connected to a wiper of which the terminal is connected to battery as long as there is an idle junction in the group. Operation of P completes the hunting circuit of the rotary magnet RM in series with CC. If P fails to operate, BF energizes on the relapse of CC and connects an interrupter over wire FLA to FL which connects SC intermittently to wire d to give a flash signal, while high resistance relay HR is connected in series with P. Relay SC operates over a low-resistance circuit when the operator restores her listening key and disconnects BF to remove the flash signal. When a junction becomes available, only HR operates and connects a fast interrupter over wire FLI to FL to give a flicker signal, SC being held over its locking circuit. To initiate hunting the operator opens the d wire to release SC. Relay BF re-operates and connects up CC, which disconnects HR to allow operation of P.

Title: Preparation of 2,2-dichloro-and 2,2-dibromo cyclopropanecarboxylic acids
IPC: C07C69/74
Filed: 1961-03-23
Abstract: 2,2-Dichloro- and 2,2-dibromo-cyclopropane carboxylic acids and substitution products thereof are prepared by the action of an alkali-metal salt of trichloro -or tribromo-acetic acid on an alkyl ester of an unsaturated acid of the formula R(R1)C=C(R11)COOH, in which R, R1 and R11 are hydrogen atoms or alkyl or aryl groups, in any permutation, followed by alkaline or acid hydrolysis of the resulting 2,2-dichloro- or 2,2-dibromo-cyclopropane carboxylic ester to yield the free acid. In the examples, (1) methyl methacrylate and sodium trichloracetate yield methyl 1-methyl-2, 2-dichlorocyclopropane carboxylate, which is hydrolysed with hydrochloric acid to yield the free acid; (2) ethyl cinnamate and sodium trichloracetate yield ethyl trans-2, 2-dichloro -3- phenylcyclopropane carboxylate, which is hydrolysed with hydrochloric acid to yield the free acid; the corresponding 2,2-dibromo compound is obtained if sodium tribromoacetate is used instead of sodium trichloracetate. Specification 978,351 is referred to.

Title: Improvements in or relating to co-ordinate switching arrangements
IPC: H01H67/30
Filed: 1958-04-02
Abstract: 827,130. Automatic exchange switches. SIEMENS & HALSKE A.G. April 2, 1958 [April 5, 1957], No. 10639/58. Addition to 797,913. Class 40 (4). In a switch of the co-ordinate type comprising magnetic contacts F1, F2 operable when a pair of intersecting horizontal and vertical coils C, A are energized and held by a further coil H1 which may be horizontal or vertical, and in which a magnetic shunt path via gaps L1, L2 is provided to prevent unwanted operation by the energization of a single coil only, a further magnetic shunt path L3, L4 for the flux due to the hold coil is provided by a re-entrant part of the outer magnetic casing. This prevents unwanted operation of the contacts should a hold coil H1 be energized simultaneously with the operating coil C. The effectiveness of the coil C may also be reduced with the same object in view, either by reducing the current or number of turns of the coil (in which case corresponding increases may have to be applied to coil A) or alternatively by decreasing the reluctance of the magnetic shunt path for the contact F1 as compared with that for F2, e.g. by an asymmetric design of the magnetic shunt so that the crosssectional area of the gap L1 is greater than that for L2.

Title: Cooling nuclear reactor fuel
IPC: G21C15/18
Filed: 1972-03-07
Abstract: 1416184 Cooling reactors UNITED KING- DOM ATOMIC ENERGY AUTHORITY 2 March 1973 [7 March 1972] 10662/72 Heading G6C An auxiliary cooling system for a nuclear reactor core comprises at least one perforated conduit extending into the core, a supply of auxiliary coolant, a pump arranged to deliver auxiliary coolant from the supply to the perforated conduit, and an intermittent flow inducing means causing the coolant to be dispensed through the conduit perforations as intermittent jets. In SGHW reactors, the main coolant A passes upwardly through vertical pressure tubes 1 housing fuel assemblies comprising fuel rods 5 supported between end fittings 6, 7. Each fuel assembly is provided with a central sparge tube 8 whose upper end is closed and whose lower end communicates with a supply of auxiliary coolant of the same kind as the main coolant. When required, auxiliary coolant is pumped from a tank 14 under control of a valve 15 by a pump 16 which delivers coolant to a rotary valve 17, which valve feeds a number of sparge tubes as at 8 in succession. As a result, the delivery from the holes 9 in the tubes 8 is intermittent. As an alternative, the delivery of pump 16 may be connected directly in parallel with the tubes 8 and pulsed so as to create oscillating pressures in the auxiliary coolant flow. In a further embodiment (Fig. 2, not shown) fluidic switches of the bi-stable Coander type are employed to induce intermittent auxiliary coolant flow. The effect of the intermittent flow is to give greater penetration of the coolant jets into the fuel assemblies for a given average water flow rate. Similar effects may be achieved with sparge tubes used in pressurized water reactors.

Title: Controlling the supply of electric currents
IPC: H01H29/28
Filed: 1919-04-30
Abstract: 146,665. Tavener, J. April 30, 1919. Motor meters.-The circuit through the shunt coil of an integrating watt-meter is closed only when one or more consuming devices such as lamps are switched on. As shown, the supply to a house is taken through a coil F of a thermal switch consisting of a balanced tube containing mercury D. When a lamp L is turned on the mercury is displaced and the circuit through the shunt coil SC closed at the contacts H. To prevent over rapid movement a second coil F<1> is used of less effect than the coil F but opposed thereto; or a resistance in shunt to the coil F may be used. In place of the thermal switch an electromagnetic switch may be used.

Title: Improvements relating to apparatus for delivering precise amounts of gas
IPC: G01F3/30
Filed: 1934-04-10
Abstract: 428,496. Delivering measured quantities of gas. BOARD OF TRADE, SECRETARY OF, Great George Street, and BOYS, C. V., 66, Victoria Street, both in London. April 10, 1934, No. 10793. [Class 54] [See also Group XXVI] An apparatus for supplying gas at a predetermined rate, suitable for use in a recording calorimeter incorporating a water-doling device as in Specification 428,486, [Group XVIII], comprises at least four cylindrical measuring bells 8 attached equidistantly to a cup-shaped rotor 11 on a spindle 3 driven by an electric motor, the lower ends of the bells and of skirts 9, 10 attached to the rotor dipping below the level A-A of a liquid seal, preferably mercury, contained in cup formed by a steel tube 2 and cast iron base 1. The gas is supplied through a nozzle 6 and a passage 7 in a cylindrical projection 5 on the base 1 to the space between the skirts 9, 10 and can then pass to the ascending bells 8 through passages 16 in the rotor and pipes 14. Gas is discharged from the descending bells 8 through pipes 15 to the spaces between the bells 8 enclosed by the skirt 9 and can then pass through a hole 17 in a cylindrical stem 13 on the base 1 and a hole 19 in the spindle 3 to the discharge nozzle 21. The inlet of each passage 16 and the outlet of the corresponding pipe 15 lie in a plane containing the axis of the spindle 3 and at right angles to a plane passing through the axes of the spindle 3 and the corresponding bell so that the bells are always open either to gas supply or discharge, except when at their highest or lowest positions. A removable cover 23 on the tube 2 excludes dust. The direction of rotation of the rotor may be reversed, the gas then flowing through the apparatus in the reverse direction. In a modification the measuring bells are formed by bores in a cylindrical rotor, the gas inlet space and inlet pipes being substantially the same as above described but the gas outlet pipes being connected to cylindrical cavities formed in the rotor connected by radial passages to an axial discharge passage. The apparatus may be clamped in straps 35, 36, Fig. 5, the strap 36 being formed with a V-edged base 39 and the strap 35 being provided with an extension 40 carrying a micrometer screw 41 resting on a supporting surface. The capacity of the apparatus is adjusted by altering its inclination by means of the screw 41 and a platform 43 attached to the straps is then adjusted until level. Should the apparatus be placed in any fresh position adjustment of the screw 41 until the platform 43 is again level will ensure the capacity being correct. A handle 44 on the strap 35 is arranged in a vertical plane passing through the centre of gravity of the apparatus so as to prevent spilling of the mercury when the apparatus is lifted.

Title: Improvements in or relating to the production of chemical conversion coatings upon metal surfaces
IPC: C23C22/78
Filed: 1962-03-22
Abstract: In a method for producing conversion coatings, e.g. phosphate or oxalate coatings, on metal (e.g. iron or steel) surfaces, a neutral aqueous non-tripolyphosphate and non-hexametaphosphate - containing cleaning solution having one or more non-ionic wetting agents in it is applied to the surface at a temperature of 20-80  DEG C. (but also within the turbidity range of the solution) and then, without rinsing, the surface is treated with a conventional coating solution. The turbidity range is defined at its lower limit by the temperature at which the solution becomes visibly turbid and at the upper limit by precipitation of the wetting agent.  The wetting agents may be addition products of ethylene oxide and either polyoxypropylenes having a molecular weight exceeding 1,000 or polyglycol ethers having a lipophilic residue, or mixtures of these compounds, and they should be present in a concentration of 0.01-5% by weight, preferably 0.1-1%.  The nitrile ion may preferably be present in a concentration of 0.05-1.5%, preferably 0.1-1%. The turbidity range may be modified by the addition of anionic wetting agents such as aralkyl sulphonates or alkyl sulphates.  After the conversion treatment the surface may be subjected to a water rinse followed by a chromate rinse.

Filed: 1975-03-17
Abstract: 1501424 Electric resistance heating BOSCHSIEMENS HAUSGERATE GmbH 17 March 1975 [11 April 1974 (2) 17 May 1974] 11095/75 Heading H5H An electric heating appliance includes a beadinsulated resistor 14, 16, Fig. 2, 122, 124, Fig. 3, in a channel beneath either a supporting surface 102, Fig. 3, or a vessel 6, Fig. 2, and a metallic heat conductive member 20, Fig. 2, 126, Fig. 3, in the channel and in thermal contact with the walls of the channel. The heating element consists of a single loop of helically coiled wire 16 extending through a series of ceramic tubular beads 14 with end leads 28 passing through two beads 24, 26 shaped to engage in apertures of the appliance. In an egg boiler, Fig. 2, the element is in a channel in a projection beneath a water containing vessel 6 cast integral with the vessel and contained in a casing (1, 2, Fig. 1, not shown). The element is retained in the channel by a cover 20 shaped to engage the protruding surface of the element. The cover is snap-fitted into the channel with peened-over portions 22 to retain it in place. The base of the groove fits the beads for better heat transfer. For a coffee making machine the heating element may lie in a groove in a projection similarly cast below a flat warming plate with the difference that the groove is deeper, with an enlarged opening to receive additionally a tube (226) through which passes water to be heated (Fig. 4, not shown). The plate, water tube and element are held assembled by springs (210) affixed to the base of the coffee machine. The springs press on the tube and through the tube and element also press the warming plate against a packing ring (208) on an inwardly extending rim of the base, to retain the plate in place. The warming plate may be a metal disc 102, Fig. 3, with the channel formed in a separate member 104 pressed by springs 110 mounted on the coffee pot base 106 against the underside of the warming plate. Aluminium water heater tube 126 is supported by shoulders 130 to avoid damaging the element.  The warming plate may have a downturned rim (162, Fig. 5, not shown) with pressed out tabs (164) to engage under a rim of a channel member to retain the member with water tube (158) and heating element (156) in the channel in place on the underside of the plate (152).
