Title: Pressure relief valve
IPC: F15B13/02
Filed: 1973-07-05
Abstract: 1428534 Fluid-pressure servomotor systems CATERPILLAR TRACTOR CO 5 July 1973 [5 March 1973] 32105/73 Heading G3P A pressure relief valve 10 comprises a main valve member 39 loosely mounted in a bore 31 with freedom for radial movement and biased by spring 41 towards a valve seat 30, member 39 having a bore 42 slidably containing a body 47 enclosing a pilot valve member 52 biased towards seat 54 by spring 53. An offset port 44 through end wall 43 of valve member 39 normally equalizes pressure in a control chamber 49 with that in chamber 24 upstream of the valve. Should the latter pressure become excessive pilot valve 52 lifts off seat 54 thus venting chamber 49 to low pressure in chamber 25 via axial port 50, radial ports 51 and axial grooves 45 in the peripheral surface of valve member 39. The pressure reduction in chamber 49 causes valve member 39 to move off its seat 30 to by-pass fluid directly from chamber 24 to chamber 25. A domed cap 57 is secured to body 47 to limit the travel thereof by abutment with a fixed cover 33. The relief valve 10 is associated with the directional control spool 23 of a fluid motor 14. The radial freedom of valve member 39 enables it to align correctly with seat 30.

Abstract: 1.236,973. Controlling shearing machines. NIPPON STEEL CORP. and MITSUBISHI ELECTRIC CORP. 5 July, 1968 [6 July, 1967], No. 32215/68. Heading B3W. Shearing of metal plates is controlled automatically using supersonic flaw detection by detecting a flaw in either end portion of a plate and its distance from a reference point by supersonic means, determining the position at which the plate is to be sheared, by feeding these valves to a computer programmed for cutting and passing an instruction to a shearing machine in accordance with the shearing position so determined. As shown, Fig.1, feelers 3 and 4 detect flaws 49, 50 while moving over a plate 48 to be sheared, detect the distance I of the end of the plate and l2, l3 of the flaws from a reference position 47 by means of length measuring devices 19-21 associated with the motors 16- 18 which drive a plate-end detector 15 and the feelers 3 and 4 respectively. These values are fed to a computer 45 including programmed control apparatus 27 and output apparatus 28 from which a cutting instruction is transmitted to a shear 29 and signal sent to a motor 40 for positioning a gauging stop 30 relative to the shear 29. The slab is fed by means (not shown) to the stop 30 located relative to the shear 29 so that the first cut will remove the flaw 49. The sound material is cut into predetermined lengths and the rear flaw 50 is then cut off. Each flaw detecting feeler (Fig. 2, not shown) comprises bars (51) and (54) carrying respectively a water-cooled transmitting and receiving supersonic oscillator (53) or (56) at its upper end. A contact agent 57 which may be one or a mixture of metallic salts is interposed between the feeler and the plate.
