Abstract: 663,416. Valves. DAHL, G. W. April 16, 1949 [April 17, 1948], No. 10252/49. Class 135. A diaphragm-actuated valve having a stem connecting the diaphragm to the valve closure member and surrounded by a sleeve movable manually between fixed abutments secured to the stem so that the permissible movement of the closure member in both opening and closing directions may be limited, comprises a valve body 10, Fig. 1, having an inlet 11 and an outlet 12 and housing a closure member 17 connected by a stem 25 to a diaphragm 27 mounted in a chamber 56 which may be supplied with compressed air through an opening 56a. The stem 25 has secured thereto an upper abutment button 26 supporting the diaphragm 27 and lower abutment nuts 85, 87, and is surrounded by a sleeve 70 having external screw-threads 73 engageable with threads in the hub of a worm wheel 77 secured against axial movement by a block 50 interposed between tubes 45, 52 connecting the body 10 to the chamber 56. The worm wheel 77 is engageable with a worm 78 rotatable by a handwheel 84 and disposable in either of one of two bores 82 in the block 50. Loading springs 64, 65 between the button 26 and an adjustable spring abutment 63 oppose the air pressure on the diaphragm whilst pointers 92, 95 secured to the stem 25 and coacting with scales 93, 98, Fig. 2, indicate the position of the sleeve and the closure member respectively. In the neutral position, Figs. 1 and 2, the valve may be fully opened by the springs 64, 65 or fully closed by the air pressure acting on the diaphragm 27. To adjust the valve so that it may never be fully closed the downward movement of the button 26 is limited on the upward movement of the sleeve 70 by rotation of the handwheel 84. To adjust the valve so that it may never be fully opened the sleeve 70 is moved downwards together with the nuts 85, 87 and the stem 25. The valve closure member 17 and its seat 15 may be modified, see Fig. 5, so that the seat is located above instead of below the valve member. In this case the alternative bore in the block 50 is used for the worm 78 so that the same direction of rotation of the handwheel 84 has the same limiting effects as before on the closure member.

Abstract: 1,259,934. Controlling cutting tool position. BLAW-KNOX CO. 4 March, 1970 [13 March, 1969], No. 10515/70. Headings B3B and B3T. In a machine tool such as a lathe having a longitudinal extending bed 10 means is provided to compensate for variations in transverse straightness of the longitudinal guideways on the lathe bed and therefore accurately control the cutting tool position with respect to a workpiece being machined in the lathe. A saddle 16 is traversable along longitudinal guideways 12 and 14 on the bed 10 by rack and pinion means 18 and a cross-slide 20 is displaceable on the saddle 16. A laser beam transmitter is secured and aligned at one end of the bed and operates in co-operation with a receiver 32 attached to the saddle, the beam emitted from the transmitter extending longitudinally of the bed and constituting a straightness reference datum. In operation, the cross-slide 20 is positioned on the saddle to correctly locate the cutting tool T in the desired operative position relative to the workpiece and the laser receiver aligned with the beam emitted from the transmitter. As machining of the workpiece progresses any lateral displacement of the saddle and hence the tool as it traverses the bed on the guides 12, 14, produces corresponding lateral deviation of the laser receiver with respect to the beam. The deviation detected facilitates the operation of a servo-valve 38 which operates an hydraulic actuator 40 which displaces a wedge member 50 carried on the saddle and which displaces the cross-slide against a spring-biased support 64 by an amount equal to the deviation in the straightness of the guideways. The normal infeed of the tool is effected by gearing and a rotary screw 26 which displaces the cross-slide.
