Patent GB-964069-A (GB)
Title: Control servomechanism for fluid operated vehicle drive assemblies
IPC: F16H3/00
Filed: 1963-04-17
Abstract: 964,069. Clutch control. TOWMOTOR CORPORATION. April 17, 1963 [Nov. 14, 1962], No. 15037/63. Headings F2D and F2L. A clutch operating mechanism for a vehicle such as a lift truck, which can be operated to provide forward or reverse drive is also operable to control the speed of the vehicle by controlling clutch slip to allow creeping or inching movement of the vehicle. A valve 45, Fig. 5, is actuated from the neutral position shown to control the supply of fluid pressure from a conduit 41 to either outlet 21, 22 which lead to the opposite ends of a cylinder housing a piston which actuates the clutch. Feed through outlet 21 actuates the piston for forward drive and feed through outlet 22 provides reverse drive. The supply of fluid to the conduit 41 is controlled by a valve 81, which in the position shown allows the full supply from an inlet 27 to a groove 52 to flow to groove 56 and conduit 58. The flow from conduit 58 to conduit 41 takes place through a restriction 63 and also through a clearance passage 65a until the pressure in the passage 41 moves a valve 70 to close the passage 65a and flow then occurs through the restriction 63 only, this reduces the velocity of the piston towards the end of its stroke to prevent jerking movements of the vehicle i.e. this action reduces the speed of the full engagement of the clutch. To control the clutch slip, the valve 81 is provided with a groove or flat 83 extending along part of the land 82 as far as a shoulder 84. When the valve 81 is moved inwards to a position in which the shoulder 84 clears the bore part 54b the fluid in groove 52 flows to the groove 56 through the flat 83 and most of the fluid in the groove 56 flows to passage 86 connected to exhaust, thus the pressure fed through passage 58 is regulated to control the position of the piston and hence the degree of engagement of the clutch. The valve 81 is connected to a bracket 98, Fig. 3, which is actuated manually by a lever 106. In the position shown, the valve 81 is in the position shown in Fig. 5 i.e. the clutch is in full engagement if the valve 45 has been actuated. When the lever 106 is depressed, the valve 81 moves inwards by rotation of a floating lever 96 to reduce the pressure to the piston cylinder device. Movement of the piston causes rotation of a shaft 15 to actuate the clutch. The shaft 15 carries a bracket 89 which on rotation in either direction, corresponding to forward or reverse drive, moves a lever 91 to the right. The lever 91 is connected to the floating lever 96 and its movement to the right acts to rotate the lever 96 to move the valve 81 outwards thus providing feedback to the valve. The position of lever 106 thus provides a corresponding engagement of the clutch to provide a controlled slip and hence creeping speed of the vehicle. U.S.A. Specification 2,861,480 is referred to.

Title: Improvements in liquid-operated regulating apparatus
IPC: G05D16/10
Filed: 1927-06-07
Abstract: 272,242. Carlstedt, R. June 7, 1926, [Convention date]. Apparatus.-In liquid-operated regulators comprising a piston servomotor, such as 1, Figs. 1 and 3, actuating a control member, such as a steam pressure regulating valve 12, the pressure supply of non-compressible liquid to the cylinder 1 is admitted on the side of the piston 2 remote from the piston rod 3 so that packing at the guide is obviated and a more sensitive control is obtained. In operation, a rise of steam pressure in the conduit 27 beyond the valve 12 is transmitted by the pipe 26 to the chamber 16 and there compresses the bellows device 17 which operates through the spring-controlled lever system 19 and increases the space between the pressure plate 20 and the nozzle 21. The consequent increased flow of liquid from the cylinder 23, admitted at 4, allows the piston to rise and, through the cord connections 9, throttles the valve 12. In the arrangement shown in Fig. 1, one end of the cord is anchored to the cylinder, at 10, the cord then passing over a pulley wheel on the end of the piston rod 3 and then to the valve which is counterweighted at 14. In the alternative arrangement shown in Fig. 3, the pulley is mounted on the cylinder 1 and the end of the cord is connected to the piston rod 3. The inlet passage 4, 5 for the liquid is provided with a cleaning pin 6.

Title: Method and apparatus for making up threaded pipe joints
IPC: B25B23/14
Filed: 1970-03-31
Abstract: 1308337 Connecting pipes by screwing ESSO PRODUCTION RESEARCH CO 31 March 1970 [4 April 1969] 15183/70 Heading B3N Apparatus for screwing together threaded pipe comprises power tongs 1 having a rotatable jaw 2 driven by a motor 5 energized by compressed air, as shown, hydraulic fluid or electricity; an hydraulic torque measuring instrument 21 adapted to send a signal to a transducer 25 which can produce an electric output signal which can be applied to an electronic controller 37; jaw 2 has projections 3 which can operate a microswitch 125 adapted to send pulses via an AND circuit 119 to a counter device 75. A strip chart (165), Fig. 2 (not shown), forms part of the controller 37 and records torque changes and the number of pulses transmitted. In operation, assuming coupling 181 to be fixedly attached to pipe 182, jaw 2 is rotated to screw up pipe 180. If a predetermined number of turns occur before a predetermined minimum torque is reached then a " reject " signal from a warble oscillator 55 occurs denoting the joining of the pipe and coupling is not achieved, viz. pipe 180 is not engaged with coupling 181. If a predetermined maximum torque is reached before a predetermined intermediate number of turns is reached then again the " reject " warble 55 is activated. This will be due to, for example cross-threading. If a minimum torque is reached before a predetermined low number of turns then yet again warble 55 is activated. A possible cause of this could be one of the cooperating threads being dirty. Satisfactory joining of the pipe and coupling is denoted by a constant frequency oscillator 52 which operates when a minimum torque is reached on or after an intermediate number of turns is reached but before a maximum number of turns is reached or when an intermediate number of turns is reached on or after a minimum torque is reached but before a maximum torque is reached. The apparatus can be used to join the pipes 180, 182 to coupling 181 simultaneously. In such case a microswitch 185 is utilized which sends pulses to a counter device 75<SP>1</SP> via an AND circuit 119<SP>1</SP>. Switch 189 has to be closed for such operation. Instead of warble 55 or oscillator 52 being operated a valve 11 in motor supply line 9 may be directly controlled.

Abstract: 1460875 Making helically wound tubing; seaming PACIFIC ROLLER DIE CO Inc 15 April 1975 [9 May 1974] 15473/75 Headings B3A B3E and B3J A method of making helically-wound pipe 1 from an elongated strip 2 of ductile sheet material comprises bending the strip into helical convolutions, joining adjacent edges of the convolutions together to form a pipe, and positioning the point at which the joining occurs relative to the axis of the pipe to maintain the desired diameter of the pipe. The strip is fed to a machine comprising a corrugating station 3, Fig. 1, a forming station 6 for bending the strip into helical convolutions (7), Fig. 2 (not shown) and joining adjacent edges (54), (55), Fig. 10 (not shown), to form a seam, and a discharge station 8 where the pipe is cut into lengths. Each corrugating roll 10 comprises a cylindrical wheel or drum (16), Fig. 5 (not shown), with annular corrugations (17) on its surface. Locking lips (38), (39), Figs. 8, 9 (not shown), are formed at the edges of the corrugated strip for subsequent interlocking by rolls 80, 84, Fig. 13. The forming station 6 includes a convolution forming mechanism having a pressure roll 46, Fig. 11, a central anvil roll 47, and a guide roll 48 intercepting the strip path from between a pair of guide plates 40. Pressure roll 46 is mounted on an inclined ramp 49 for adjustment relative to the strip path between rolls 47, 48. The rolls 46-48 each comprise a plurality of individual rollers (56). The axial position of roll 48 may be adjusted relative to the other two rolls by a screw 71. A flange completing roller 75 is mounted on a block 65 for completing the forming of flanges (38), (39). At or just after the point of intersection of edges (54), (55) of the strip, the interengaging flanges (38), (39) are passed between a pair of crimping rolls 80, 84. The radial positioning of these rolls relative to the pipe axis controls the diameter of the pipe during forming. The rolls comprise respective bevelled wheels 85, 105 having inter-engaging knurling 124 on their bevelled surfaces to form a continuous series of spaced crimps or indentations in the continuous seam. Both rolls are vertically adjustable by adjusting screws 95, 119. Diameter changes of Œ one fourth inch can be made by adjusting the vertical positioning of the rolls 80, 84. Major diameter changes can be made by varying the angle of the strip entering the forming station and the position of pressure roll 46. The adjustment of the rolls 80, 84 may be manual, automatic or one roll may react to the manual adjustment of the other roll. The diameter of the pipe may be monitored by a belt or loop detector and activate a servomechanism as necessary to adjust the position of the rolls. Smooth-wall welded seam pipe may be produced and the crimping rollers may be replaced by plain, cylindrical rollers straddling abutting edges of the helically-wound strip.
