Abstract: 538,570. Uniting by fusion. BABCOCK & WILCOX, Ltd., HARRIS, H., and JONES, J. E. Feb. 1, 1940, No. 1951. [Class 83 (iv)] In a method of butt-welding, the metal of the edge, at least at the base of the groove, of a part of non-austenitic alloy steel containing up to 3 per cent of nickel, chromium, tungsten, vanadium or molybdenum, or up to a total of 3 per cent of two or more of these metals, consists of weld deposited metal of the same character and thereafter similar weld metal is deposited in the groove to effect the weld. Cracking of forged or cast work parts and of the weld metal in the vicinity of the base of the joint is thus avoided. In a U-joint between parts 4 both of which are of such non-austenitic alloy steel, the edges 5 are machined and then lips 3 of similar metal are weld deposited thereon. After machining the faces of the groove it is filled in a series of layers with similar weld metal by gas or electric arc welding. In a modification one wall of the joint may be a plane edge and if such part is of mild steel no preliminary weld deposited coating thereon need be applied. In making a V-joint between part of such non-austenitic steel the whole of each surface may be first provided with a weld deposited coating of such alloy steel. The metal of the work, deposited layer and fillings may be of the same chemical composition, particularly in making chemical plant, or the first filling layer may be of mild steel. In making a pressure vessel such as a superheater box or portion of a steam line, the whole of the material may consist of ¢ per cent molybdenum steel. After the welding groove is filled with weld metal, metal may be cut away from the underside of the seam and weld metal deposited from that side.

Abstract: 1285951 Valves; antiskid systems AUTOMOTIVE PRODUCTS CO Ltd 9 Jan 1970 [14 Jan 1969] 2127/69 Headings F2F and F2V In an hydraulic or pneumatic antiskid braking system a valve 17 is provided which has pilot valves having ball heads 67, 68 actuated by solenoids 72, 73 which are energized by a skid sensing device to allow the pressure in the brake cylinders 19 to be relieved when a skid is detected. In the embodiment shown hydraulic fluid is pumped by an engine driven pump 10, to valve 17 by way of pressure blow-off valve 12, conduit 15, brake valve 14 and conduit 16, and in normal braking operation passes through passages 44, 41 and 42 to brake cylinders 19. When a skid is detected by a change in deceleration of a wheel, an energizing signal is passed to solenoids 72, 73 which moves members 67, 68 to close off passages 64, 59 respectively. Hydraulic fluid from the pressure source then passes through passage 58, chamber 56 and passage 54 into a chamber 47 to force a diaphragm 49 downwardly thereby closing off passages 41, 44. Hydraulic fluid in a further chamber 48 passes to an exhaust or drain 11 by way of passage 55, chamber 57, passage 62, chamber 64, passage 62 and conduits 24, 21 fluid pressure in the motor cylinder then forcing a diaphragm 51 to move downwardly to connect chamber 41 with an outlet passage 46 connected by way of conduits 22, 21 to drain 11 thus relieving pressure in the cylinders 19. In an embodiment in which the release of the brakes is arrested before reapplication is initiated there is provided in addition to a skid sensing device 77, Fig. 6 (not shown), a comparator (81) responsive to a rate of change of wheel rotational speed and connected to a relay coil (83) actuating a contact (86) connected to the solenoid 73. When the coil (83) is de-energized contacts (86) open deactivating solenoid 73 so that the brake cylinders are cut off from exhaust but remain isolated from the pressure source until the vehicle wheels have speeded up sufficiently to stop the sensing device (17) generating a signal to two relay coils (84), (85) which energize solenoids 72, 73.
