Title: Improvements in ceramic bonding
IPC: C22C5/04
Filed: 1965-04-30
Abstract: <PICT:1108764/C6-C7/1> Bonding a refractory ceramic member to a refractory metal surface includes forming on the ceramic member a tightly adhering spongy porous layer of tungsten and/or molybdenum, then coating the layer with a refractory metal and brazing the refractory metal surface to the metallized ceramic, the refractory metal coating consisting of rhenium, molybdenum-rhodium alloy or molybdenum ruthenium alloy.  A body of alumina 1 has applied thereto a suspension of molybdenum oxide or tungsten oxide or mixtures thereof in a solution of nitrocellulose in amyl acetate and the body is then heated in hydrogen to reduce the oxides and sinter a spongy layer 2 to the body.  The powdered metals instead of their oxides may be employed.  An aqueous solution of rhenium heptoxide is applied to the sponge and heated in hydrogen to reduce the heptoxide to rhenium metal 3 which covers the surfaces of the spongy layer without filling the pores of the sponge.  To the rhenium coated sponge layer a molybdenum body 5 is brazed.  In a modification the sponge layer is coated with a suspension of 40% ruthenium oxide balance molybdenum oxide in a solution of nitrocellulose in amylacetate and the assembly fired in hydrogen to form a eutectic ruthenium-molybdenum alloy coating on the sponge which fills the pores.  Instead of a ruthenium and molybdenum alloy a rhodium-molybdenum alloy may be used.  The coated ceramic is then brazed to a tungsten, molybdenum or rhenium plate.  If the material for coating the sponge and for brazing are of the same composition the coating and brazing may take place simultaneously. The metals or alloys may be used instead of the oxides.

Title: Shaft sealing device
IPC: F04D29/10
Filed: 1971-06-04
Abstract: 1312585 Rotary shaft seals SONESSON PUMPINDUSTRI AB 4 June 1971 [22 June 1970] 18962/71 Heading F2B To promote heat exchange the gland 7 of a rotary shaft seal is formed with a recess 23 which surrounds the shaft 2 and has an inlet 24 and an outlet 25 for heat transmitting fluid. In the embodiment shown for a pump dealing with hot liquid, packing 6 is compressed in a stuffing- box 4 in the pump housing 3 by the gland 7 and the recess 23 is closed at its outer end by a sealing ring 20. Liquid leaking past the packing 6 enters the recess 23 through the clearance 24 between the shaft and gland and acts to transmit heat from the shaft to the gland which is cooled by a coolant circulated through a channel 9 therein having an inlet 11 and an outlet (12, Fig. 2). A cooling water passage 13 is formed in the pump housing 3. The gland wall 10 around the recess 23 may be corrugated or formed with one or more helical grooves. If the packing is such that substantially no leakage occurs along the shaft, the recess 23 may have a separate inlet connected to an external source of heat transmitting fluid. In some cases the channel 9 may be omitted. If the pumped fluid is so cold as to require heating of the shaft, a heating agent is circulated through the channel 9.

Abstract: 740,810. Variable resistors and potentiometers. NATIONAL RESEARCH DE - VELOPMENT CORPORATION. Oct. 15, 1953 [July 28, 1952], No. 18975/52. Class 37. [Also in Group XXXVIII] Relates to devices in which resistance variation is produced by change in position of tangential contact between a resistance element and a contact element. There may also be change in area of contact and at least one of the elements has a radius of curvature which is large compared with the length of the curve. The curve may be an arc having variations in curvature to suit the required output law. The position of the line of contact relative to either end of the resistance element is variable by a rolling motion of one member relative to the other which is substantially free from slip and is produced by a single displacement input at one part of one of the members. The invention is described with reference to transducers in which fluid pressure is the primary variable. In the potentiometer of Fig. 4 and 4a a frame 9 pivots about 19 at mid-point of fixed resistance element 3 so that end 2 of conducting bar 1 is displaced in a circular path and moves the tangent tap along 3 with contact pressure being maintained by tension-spring 22. Figs. 3 and 3a show a potentiometer in which a hairpin spring 16 maintains contact pressure between a curved resistance element 3 and a curved contact element 17 which is an extension of lever 12. The elements 3, 17 pivot respectively at 18, 13 and may have involute profiles or the profiles necessary for a particular output law. Specification 600,620 is referred to.

Abstract: 1376368 Winches UHER PATENT AG 27 April 1972 [29 April 1971] 19592/72 Heading B8B [Also in Division F2] A winch comprises a chain pulley 3 rotationally freely mounted on a drive shaft 2, and drivingly coupled thereto through a clutch comprising a coned recess in the pulley 3 engageable by a conical member 4 axially slideable on the shaft 2 under the control of a threaded coupling therewith. The conical member 4 is secured to a sleeve 6 having internal threads engaging threads 7 on the shaft 2, and a radial flange 8 on the sleeve 6 is formed as a cam for engagement with a pawl 10 pivoted to the winch frame 1. When the shaft 2 is turned in the load hauling direction through gearing 12, 13, 14 and handle 16, and the pawl 10 is manually applied against spring bias to engage the cam 8, the sleeve 6 is held rotationally stationary and screws along the shaft 2 into clutch engagement, whereupon the pawl 10 rides out of a recess on the cam due to increased resistance to cam movement and the clutch engagement increases until the load torque is overcome. To release the clutch, the shaft rotation is reversed and the pawl brought into engagement with another recess in the cam, this recess being shaped to prevent any overriding thereof, whereupon the cone 4 is disengaged with unthreading of the sleeve 6. In the embodiment of Figs. 3-5 (not shown) the shaft is driven through a worm and wheel and the pawl is automatically released from the cam during the unwinding operation by a disc mounted for restricted rotation on the cam axis, and which is rotated by pin engagement with a stationary pin in the clutch disengaged position of the sleeve, to dislodge the pawl from the cam recess.
