Abstract: 276,574. Aktiebolaget Priorverken. Oct. 2, 1926, [Convention date]. Turning wood-screws. - In apparatus for threading the points of wood-screws, a cutting- tool 7<11> is mounted on a slide 7 guided in an inclined groove on the lathe slide-rest 3, which is attached to a sleeve 4 slidable in a fixed bearing 5. A rod 1 slidable in the sleeve carries a link 6 attached to the slide 7. In operation the rod 1 is advanced by a cam and, through a spring 2, feeds the slide-rest towards the work 7<1> until a flange on the sleeve 4 encounters the bearing 5. The spring 2 is then compressed on further motion of the rod 1 and the slide 7 is carried along its inclined groove by the link 6 to cause the tool to operate on the tapered point of the work. When the cutting operation is completed a projection 9 on the slide 7 rides off a spring detent 8, which then snaps behind it, so that when the rod 1 is retracted the tool will be withdrawn clear of the work until the detent is rocked by an incline 10 to release the projection 9 and allow the spring 2 to withdraw the slide 7 along its groove.

The valve 2 is biased to an open position by pressure liquid delivered through non- return valve 20 into chamber 5 beneath a piston 3, the chamber 5 being connectible to the drain 10 via a pilot valve 25 and throttle 23, and is biased to its closed position by a pneumatic pressure delivered to a chamber 13 above a piston 14 via change-over valve 31, non-return valve 32 and reducing valve 33. With the valves 2 and 25 in the positions shown and the valve 31 moved to communicate pneumatic pressure to the chamber 13, the pressure in chamber 5 causes the valve 2 to open, thereby connecting the chamber 4 to drain and opening the valve 25 mechanically via rods 12, 15, 28. The consequent drop in pressure in chamber 5 causes closure of the valve 2 whereby the valve 25 is closed and the pressures in chamber 4 and 5 build up again ready for the next cycle. The pressure of the pulses is adjustable by the reducing valve, and the pulsation frequency is adjustable by the throttle 23.

Title: Improvements in Automatic Slack Adjusters for Railway Brakes and the like.

IPC: B61H15/00
Filed: 1917-05-16
Abstract: 109,045. Djurson, A. R. K. Aug. 22, 1916. Addition to 14161/15. Compensating for wear.-Relates to automatically-actuated slack-adjusting means for vehicle brake mechanism in which, as described in the parent Specification, the amount of rotation given to a turn-buckle for varying the length of a rod in the mechanism is dependent only upon that part of the movement of the mechanism which arises from the slack in the system, and not also upon that which is due to straining of the mechanism consequent upon the development of the braking-pressure. According to the present invention, the turnbuckle is actuated during the release instead of the application movement of the mechanism. An arm 10 adapted, on its return movement, to rotate the turn-buckle 12 by a friction ratchet 19 is moved freely upwards during the application movement of the brake piston 4 by connexions 5, 8 and a spring 17 until it becomes gripped between the collar 18 on the turn-buckle and the part 14, owing to tension having developed in the system. Subsequent movement of the mechanism 5, 8 merely compresses the spring 17. During the release movement of the piston, the rod 8 at first moves idly downwards an amount corresponding to the previous compression of the spring, and a collar 15 on the rod 8 then engages the arm 10, so that the turn-buckle is rotated and the adjustment of the slack effected. The friction ratchet comprises a coil spring 19 arranged within the collars 11, 18 rigid respectively with the arm 10 and turn-buckle 12. A spring 21 wound reversely as compared with the spring 19 locks the turn-buckle to the member 14 to prevent possible rotation of the turn-buckle during the application movement of the mechanism.

Abstract: 961,881. Photo-electric investigation of paper sheets. NEWTOLAIR CONTROL CORPORATION. Feb. 23, 1962, No. 7064/62. Heading G1A. The invention relates to apparatus for continuously measuring the basis weight of a moving sheet 14 of paper and comprises a radiation source such as a light source 11 from which is directed through the sheet, a beam 13 the wavelength of which is restricted to a particular region by filters 15, 16 so that the energy detected by a photo-cell 18 is modulated by the fibre content of the sheet and by absorption by the bond structure of the cellulose molecules but is unaffected by the moisture content of the paper. The output signal from the photo-cell 18 is fed to an A.C. amplifier 28 where the D. C. component of the signal is blocked by a capacitor 25 and the remaining A. C. component which varies in relation to variations in the basis weight of the paper is amplified and then rectified by a circuit 44. The approximate r.m.s. value of the rectified A. C. is measured by a meter 51 calibrated in terms of basis weight. For higher basis weight papers, the paper fibres are closer together thus producing an A. C. component of higher frequency and thus due to the frequency response of the amplifier a higher r.m.s. value of the rectified component. In a further embodiment (Fig. 2 not shown) an additional system consisting of a photocell, light source, amplifier &c. similar to above is provided but the filters are chosen so as to restrict the wavelength of the beam to a region where the moisture content of the paper produces an error in the photo-cell signal. The resulting output from this additional system is compared with the output from the first system in a differential amplifier circuit and the difference in the signals is fed to a vacuum tube voltmeter circuit which includes a meter calibrated in terms of moisture content of the paper.
