Title: Improvements in or relating to telemetering systems
Inventor: ROBINSON HUGH ALVARO
IPC: G08C19/16
Filed: 1950-03-14
Abstract: 678,324. Telemetering. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. March 6, 1951. [March 14, 1950] No. 6295/50. Class 40 (i). In a telemetering system wherein impulses are transmitted at a rate proportional to the measured quantity, a capacitor is charged to a predetermined voltage on the receipt of each impulse and thereafter discharges through a resistor until receipt of the succeeding impulse when the capacitor is momentarily connected to a much smaller capacitor, the potential of which is displayed and indicates the quantity. Should the first capacitor be discharged to a potential lower than that of the small capacitor, the latter is rapidly discharged to the potential of the first capacitor. As shown, each impulse over line 70, 11, operates a relay A which operates a delayed release relay B. At the end of each line impulse, A releases to de-energize B which holds however for its delay period. During this time a condenser C1 is fully charged over contacts a2, b1, a resistor R3 from the H.T. supply leads 12, 13. When B releases C1 commences to discharge through resistor R2 and a non-linear resistor NLR of the silicon carbide type, the potential across C1 during discharge being substantially inversely proportional to the time of discharge. When relay A operates on receipt of the next line impulse, the remaining charge on C1 is applied over a2 to a much smaller capacitor C2 which thus assumes the potential of C1. The potential of C2 is measured by a valve voltmeter M calibrated in terms of the quantity being measured. When capacitor Cl is again fully charged upon release of relay A, the meter reading remains due to the charge held by C2. Subsequent line impulses are effective in the same way to apply the remaining charge on C1 to C2 so that the meter reading varies according to the time interval between successive impulses, i.e. to their frequency. If the impulse frequency falls so that C1 discharges to a potential below that of C2 the charge on C2 leaks away by way of diode V2, R2, NLR. Hence, if the line impulses cease, C2 discharges completely to reduce the meter reading to zero. A contact device in the meter may actuate an alarm under such conditions. The relays A, B may be replaced by electronic switches.

Title: Portable machine for facing pipe flanges
IPC: B23B3/26
Filed: 1953-03-09
Abstract: 749,258. Portable turning-apparatus. RENNIE, J., and REEKIE & SONS, Ltd., D. June 9, 1954 [March 9, 1953], No. 6413/53. Class 83 (3). A portable pipe-flange-facing machine comprises a stationary centralizing support with radial arms to engage the internal wall of a pipe, a slow-speed rotary carrier located in front of the support, a tool-holder on the carrier, means on the latter for feeding the tool-holder across the flange, the feeding means being operable by the rotation of the carrier, a rotary driver on the centralizing support and transmission gearing between the driver and the carrier. The centralizing support consists of a circular portion 10, Fig. 4, a flange 11 and a central hub 12. The support also includes a number of inwardly-radiating integral projections 13, Fig. 2, which are screwed to receive sets of locating- members 14 by which the support is secured to the inside of the pipe. A cover-plate 21, rotatable about a bearing 21A, Fig. 4, closes the outer end of the support. The bearing 21A is carried by a spindle 20 secured to the hub 12. The cover plate 21 has transverse guideways 29B, Figs. 1 and 2, which support a slide 29. Handles 41 on the plate 21 provide for lifting and positioning the machine. The slide 29 carries a tool-holder 30, Fig. 2, with an adjustable tool 30B. The holder is fed radially by a screw 31 either automatically (see below) or by hand for initial adjustments, by turning the end 31D of the screw. A switch-block 20B secured to the non-rotating spindle 20 carries an extension 35 housing a spring-pressed pawl 34, adjustable by nuts 37, 37A, to engage the teeth of a wheel 33, secured to the screw 31, to feed the tool on each rotation of the plate 21. An electric motor 18 secured to the underpart of the support fits into the pipe. A pinion 23 on the motor shaft 18A, Fig. 4, drives, through reduction gearing 24-28, an externally toothed ring 22 secured to the inside of the cover-plato 21. Other power motors may be used for the drive, and for small pipes a manually-supported external motor might be employed, or the machine may be hand-driven. The slide 29 may be tilted about pins 42 to give the machined face a slightly conical form.

The apparatus comprises a frame 1 supporting columns 2, 3 in which a support 4 is vertically slidable by a ram 7. Rods 9 and 10 mount a slide 5 operated by a ram 11. The head of the slide rotatably supports a shaft 15 which can be driven by a motor 17 through a coupling 16. A chuck 16 is attached to the shaft. The chuck has a mandrel 6a movable by means of ram 21, lever 20 and ring 19. Forward movement of the mandrel causes clamping member 6b to grip a socket 22. In operation a conveyer 25 feeds a socket to a position perpendicularly below the required position. Slide 4 is in a lowered position and ram 11 is in a retracted position. The slide 5 is fed so that the chuck engages the socket. Ram 21 is operated so that the chuck grips the socket. Slide 4 is then fed upwardly. When the two members are screwed together the force applied to the socket causes it, together with the chuck 6 and slides 4 and 5 to be pressed down against the holding power of ram 7.

Abstract: 1386405 Constant-tension spring units PIPE SUPPORTS Ltd 20 March 1972 [13 March 1971] 6822/71 Heading F2S A pipe 1 (such as a steam pipe in an electricity generating station) is connected for support, by means such as a pin 15 mounting an eye bolt 16, to a lever 10 pivoted at 11 on a frame 12, there being spring means (not shown) acting between the frame and lever; the support has either means for adjusting the distance between the position where the spring means acts on the lever and the pivot 11 or else means for adjusting the distance D between the position where the load-carrying means 15 acts on the lever and the pivot 11, the adjusting means including co-operating components on the lever 10 and frame 12 to decrease from an initial value the distance of the spring means or such adjusting means to increase from an initial value D1 the distance D1 of the load-carrying means 15, during movement of the lever from a first position corresponding to a cold supported pipe to a second position corresponding to a hot supported pipe (containing steam) and to prevent subsequent return of the particular distance to its initial value during at least a major part of the travel of the lever from its second to its first position. The spring means and the load may act on a single arm lever but as shown there is a separate load-attaching arm, shown in the position 38 in which the supported pipe is full of cold water. As the water and pipe become better, the pipe moves downwardly and the lever 10 pivots anticlockwise about the pin 11. The loadsupporting pin 15 is supported at its ends in slots 14 in a pair of parallel plates 13 which constitute the lever 10. The load-attaching arm is at a position 20 when there is saturated steam in the pipe and the major axes of the slots 14 are horizontal. Further pivoting of the arm causes downward inclination of the slots so that the pin 15 moves in a direction away from the pivot pin 11 to a distance D2. To maintain the distance D2 as the pipe re-cools and rises and the load arm consequently rises, i.e. to restrain movement of the pin 15 back along the slots 14 towards the pivot pin 11, there is a pair of arms 24 pivoted on the respective lever plates 13 at 25 and each receives one end of the pin 15 in an aperture 26. Each of the apertures 26 is oval with its major axis transverse to that of the adjacent slot 14. At its free end, each arm 24 bears a cam follower 27 for coaction with a cam 28 projecting from the inner face of a respective side plate 12 of the frame which bears the pivot pin 11. Arrows 32 indicate the paths of the followers 27 around faces 29, 30 of the cams 28. To ensure the movement of pin 15 away from pin 11 as the lever pivots beyond the position indicated by line 20 there may be another cam 31 for coaction with the follower 27 of each arm 24. This cam also prevents the pin 15 digging into the surfaces of the slots 14 although this may be prevented by yet further cams and followers.
