Title: Chromium plating and power supply therefor
IPC: C25D5/44
Filed: 1959-12-21
Abstract: In the electrodeposition of chromium plate on aluminium and other metals, a pulsating current is used which at each cycle has a low or nil voltage period during which no plating occurs.  It is stated that a chromium hydride compound is formed on the surface of the metal, which during the voltage nil period decomposes depositing chromium with release of hydrogen.  The power supply may be single phase full wave rectified voltage, or three phase half wave rectified voltage in which one phase relationship is reversed, or a two-phase half wave rectified voltage of which the phases are 120 degrees apart. The circuits concerned are illustrated.  The "nil" voltage period of each cycle is about 1/20 to 1/3 the plating period. Preferably the plating bath contains chromic acid, sulphuric acid and suspended silica, the ratio of CrO3/SO4 being 110 to 1 to 140 to 1. The silica used should be in a finely divided readily dispensable form.  Preferably the aluminium surface after normal cleaning processes is pre-treated to replace the oxide film by a salt which is removed in the plating bath. The first pre-treating solution contains sulphuric acid, chromic sulphate and aluminium sulphate, at 140 to 200  DEG F., and after washing, the aluminium is then immersed in a second solution containing sodium dichromate and bisulphate at 70 to 160  DEG F., a little aluminium sulphate may also be added.  After washing the aluminium is then plated with chromium to give a plate -3 mils thick. If desired an overcoat of nickel may then be applied and a top plate of bright chromium. In examples aluminium, brass, and steel surfaces are treated.

Title: Feeler gauge especially for honed bores
IPC: G01B5/08
Filed: 1971-09-17
Abstract: 1327018 Grinding; gauging Z W GEHRING 17 Sept 1971 [19 Sept 1970] 43408/71 Headings B3B and B3D A device for measuring the diameter of the bore 6 of a workpiece 2 in a honing machine comprises a feeler body 29 which is movable in a direction parallel to the axis of the bore so as to engage a feeler member 30 with a marginal edge of the bore and, under a predetermined load, when the bore has reached a finish dimenhion, moves on to the surface of the bore. The feeler body 24 is in the form of a hollow cylinder which is provided with at least one slot 28 to from spring arms carrying feeler members 30 of hard metal at their lower ends, the members saving part conical 31 and part spherical 32 surfaces. The body is integral with a piston 19 displaceable in a cylinder 16 having chambers 34, 35, differential pressure in the chambers urging the feeler members 30 into engagement with the marginal area of the bore 6. When the bore reaches a predetermined size, the differential pressure causes the feelers to engage the surface of the bore. Different differential pressures alter the force with which the feelers engage the marginal area and hence a difference in the size of the bore when the feelers enter the bore. The cylinder is carried by a plate 10 which, when the honing tool is engaged with the bore, abuts a stop plate 21 secured to a clamp 26 for the workpiece, the plate 10 being slidable on rods 9 mounted on a holding element 8 on the sleeve 43 of the spindle 3 of the machine, the spindle being connected to the shaft 5 of the tool which passes through the feeler body 29. Springs 13 act to press the plate 10 against the stop plate 21 in the operative position. A flange 47 extends from the upper end of the feeler body and, upon the feeler members moving on to the surface of the bore when the finished size is reached, activates a switch 49 to terminate the honing operation.

Abstract: 1,055,158. Valves. M. H. GROVE. Nov. 4, 1963 [Nov. 13, 1962; Jan. 23, 1963], No. 43475/63. Heading F2V. A high-pressure seal e.g. for pressures above 200 p.s.i. is provided between a valve body and a closure by an annular seal member of relatively hard resilient material nylon which surrounds a fluid passage and which has an annular insert of softer resilient material, e.g. synthetic rubber of 60 to 80 Durometer hardness, bonded within a recess therein and which engages the closure. Synthetic rubber insert 32 is moulded within machined nylon seal member 21 which is assembled as a shrink fit from boiling water upon carrier ring 22. The seal is urged into contact with a gate valve closure 11 (Fig. 1, not shown), having a port 16, by a series of springs 23 circumferentially spaced around a mounting ring 17, interfitting a bore 18 machined in the valve body, within which a flange 29 of seal member 21 is a snap fit to limit the displacement thereof by engagement with a shoulder 31. A sediment guard 24 comprises a split ring inserted in an annular recess 26 of the ring 17. The insert 32 is disposed within and projects from a seal member groove with tapered side walls which, as the seal member is urged towards the closure with increasing force, deflect inwards to increase sealing compression thereupon. A secondary seal is effected by the carrier ring 22 in the event of failure e.g. by fire, of seal member 21. The soft insert 32 exerts a wiping action upon the closure 11. The seal is effected at a diameter smaller than that of the bore 20 exposed to upstream pressure, which enhances the sealing effect. In a wedge gate valve (Fig. 12, not shown), a soft rubber insert 66 is retained within an annular seal member 63 screwed into the valve body.

Title: Improvements in pump regulating devices
IPC: F04B49/08
Filed: 1965-10-15
Abstract: 1,049,850. Fluid-pressure servomotor systems. ROBERT BOSCH G.m.b.H. Oct. 15, 1965 [Oct. 16, 1964], No. 43705/65. Heading G3P. A device for regulating the angle of a swashplate of a pump 10 in accordance with the delivery pressure comprises a balance beam 49, pivoted at 50 and subjected to an adjustable loading spring 52 and the outlet pressure acting on a valve 30. The valve is located in a transverse bore of a piston member 24 whose smaller fuse 27 is subjected to pump outlet pressure while the larger fuse 26 is connected to pump outlet or exhaust under the control of valve 30. In operation, if the delivery pressure increases, the valve 30 rises and rotates the beam 49 and outlet pressure flows through bore 38 of piston thusmoving the piston to the right to reduce the pump displacement. This movement of the piston reduces the moment applied to the beam 49 by the valve 30 and the spring 52 this acts to recentre the valve. The valve 30 may act on the beam 49 through a second lever. In a modification, a second valve subject to outlet pressure opens to move the piston to zero pump displacement at a predetermined pressure. In a further modification the valve controlling the piston 24 may be a rotary valve at the pivot 50.

Abstract: 1409359 Measuring expected thaw subsidence TEXACO EXPLORATION CANADA Ltd 18 Sept 1973 [10 Oct 1972] 43708/73 Heading G1A To measure the expected subsidence of a frozen earth formation 3 in the event of a thaw, a logging tool 1 is lowered into a borehole in the formation and provides electrical pulses E 1  to a receiver 14 by irradiating the formation with gamma rays and detecting gamma radiation therefrom. The pulses are transmitted over cable 7 to rate meter 57 in the receiver and a rate R signal is converted in accordance with D=(log R-X).k<SP>-1</SP> to a density D signal where k, X are constants. The density signal is converted in accordance with I v =57(2.65-D) to a signal E 5  representing percent volume of ice in the earth formation I v . This in turn is combined with a constant voltage V 6  representing C, the residual thaw porosity, according to I v -C = I exc, the percent volume of excess ice. The depth Z of the tool is measured by counting rotations of wheel 9 over which the cable passes and which closes switch 44 once per revolution. The expected subsidence S derives from the equation, S= <SP>#z</SP> o  Iexc.dz and is produced from integrator 80 and counter 81, in the form of signal E 8  recorded at 55. Records of D, I v  and Iexc. are provided.

Abstract: 438,735. Knitting- machines. MELLOR, BROMLEY, & CO., Ltd., BROMLEY, T. C., and SHORTLAND, A., St. Saviour's Road East, Leicester. June 6, 1934, No. 16829. [Class 74 (ii)] In thread-feeding means for knitting- machines, opposed rotary members between which the thread passes on its way to the needles, or opposed co-operating rotary members one of which may be a feed member, are mounted on parallel axes which can be moved apart, manually or automatically, to vary the tension at wh ch the yarn is fed. In the construction shown in Figs. 1 and 3, a feed wheel 1 cooperates with an opposed rotary member 2 having a thread engaging formation made up of a series of bits, blades &c. 3 which are movable radially in a trick wheel or dial 4 under control of a cam 7, the wheel 4 being carried by a shaft 15 which is driven through intermediate gears from the needle cylinder or a ring gear 65 thereon. The cam 7 and feed wheel 1 are respectively fixedly and rotatably mounted on an arm 8 on a spindle 12 which is movable manually or under control of pattern mechanism acting through a ring 25, link 24 and a lever 23 to shift the cam and the bits 3 relative to or towards and away from the axis of the wheel 2. The supporting spindle of the wheel 1 is adjustable on the arm 8 by means of a nut 20. Alternatively one or more feed wheels such as 1, supported independently of the cam 7, may be urged towards the bits 3 by means of springs. In a modification, Fig. 4, one or more grooved spring-controlled feed wheels 1<a> co-operate with a rotary member comprising a series of blades 3<a> which are movable radially under control of a cone 48 or a cam so as to provide a peripheral formation of expansible and contractible character. The blades 3<a> are pivotally mounted on a ring 38, which is driven through gears 61-56 from a ring gear 65 or the needle cylinder, and are held in contracted condition by a spring 45. The cone is moved axially by a plunger 47 operatively connected to pattern &c. mechanism. The feed wheel 2 may be replaced by a wheel of variable diameter, e.g. of foiled character, or one of various diameters, e.g. a stepped cone which can be moved axially. Or, instead of employing such a wheel as a feed wheel, it may be used to drive feed members of usual form by co-operating with one of the feed wheels either direct or through an intermediate wheel. In a further modification a series of cam actuated radially movable blades or jacks is provided in the tricked dial of a cylinder and dial machine for co-operation with a feed roller.
