Title: Apparatus for alignment of pipe sections
IPC: B21D39/04
Filed: 1970-06-09
Abstract: 1,267,792. Welding clamps. HYDROTECH SERVICES Inc. 9 June, 1970 [9 June, 1969], No. 27995/70. Heading B3R. [Also in Divisions E2 and F2]  In an apparatus for aligning two pipes, a clamp 11, 12 (Fig. 1), is attached to each pipe end 13, 14, respectively, and at least one rigid member 20 is supported between the clamps, an abutment (e.g. 64<SP>1</SP>, 58, Fig. 6) being provided between the member 20 and at least one of the clamps, and the member 20 and said one clamp being articulatedly joined. Means associated with said one clamp are provided to bring member and clamp into abutting relationship whereby they take up a predetermined relationship such that the two clamps (and thereby the pipes) become aligned. As shown, in one embodiment the clamps 11, 12 (Fig. 3), comprise three segments 25, 26, 26 pivotally interconnected at 27, 27. Each segment 25, 26, 26, carries two axially spaced radial arms 32, 35, 35 which may be expanded to the chain dotted positions or closed around a pipe x by hydraulic jacks 41. Hydraulic actuators 50 (Figs. 1, 3, 6) are supported on each pair of radial arms 32, 35, 35, and comprise jacks with pistonrods 59 terminating in ball ends 60 (Fig. 6). These ends 60 are universally held in the ends of the rigid members 20 so that the clamps are articulatedly joined. Cones 58 and sockets 64<SP>1</SP> form the abutments. On moving piston-rod 59 to the right a cone 58 on the actuator 50 abuts with a socket in the end 64 of member 20 so as to align the member 20 and the corresponding clamp in predetermined relationship. Thus the clamps may be fitted to the pipes with the actuators 50 relaxed, and subsequently, on activating actuators 50, the clamps are caused to align, thereby aligning the pipes to which they are clamped. In an alternative embodiment the ball ends of the piston-rods 59 are omitted and wires (81) (Fig. 7, not shown) interconnect rigid members (82) and actuators (80), e.g. by being loosely threaded through the members (82). In a further embodiment only two rigid members (97) (Fig. 8, not shown) are used, these being bowed, and the actuators (95) being inclined outwardly from the axis of the clamps (91), (92). In this embodiment the abutment surfaces are pyramidal to ensure both rotational and longitudinal alignment of the members (97) and the clamps (91), (92), An hydraulic operating valve 21 (Fig. 1) may be used to control the jacks and actuators, and may also control an hydraulic connecting sleeve 15 when so desired. The clamps 11, 12 may be provided with inserts 24 (Fig. 3) to allow them to accommodate different sizes of pipes, and one of the clamps may be provided with rollers to allow axial movement of one of the pipes consequent upon operation of actuators 50. The apparatus is suited to aligning pipes in difficultly accessible places (e.g. under water) while they are joined (e.g. by hydraulic connector or by welding).

Title: Improvements in and relating to helicopters
IPC: B64C27/04
Filed: 1946-09-23
Abstract: 617,290. Helicopters. CIERVA AUTOGIRO CO., Ltd., PULLIN, C. G., and SHAPIRO, J. S. Sept. 23, 1946, No. 28458. [Class 4] In a helicopter having two or more rotor assemblies with horizontally spaced centres, each assembly comprising a pair of closely associated rotors driven in opposite directions, control in yaw is obtained by unbalancing the reaction torques of the rotor assemblies, by differential variation of the collective pitches of the individual rotors of each assembly, and control in pitch or/and roll is obtained by differential variation of the lifts of the rotor assemblies by variation of the collective pitches of the individual rotors in the same sense. The invention is shown applied to a helicopter with three assemblies of coaxial, contra-rotating rotors 3a, 3b, 3c, of which the rotor 3a is placed forwardly of the centre of gravity and on the longitudinal axis, and the rotors 3b, 3c are disposed side by side to the rear of the centre of gravity. The rotors are driven by two engines 5a, 5b through junction and distribution gear-boxes 6, 7 and transmission shafts 8a, 8b, 8c. Each rotor assembly, Fig. 4, comprises non-articulated blades 25, 26 mounted on coaxial sleeves 19, 20 rigid with bevel wheels 17, 18 meshing with a pinion 16 at the end of the associated transmission shaft. Pitch control arms 30 of the upper blades are actuated hy a yoke 37 carried by a central shaft 38 connected to a lever 65 and the control arms 31 of the lower blades are operated by a second yoke 36 mounted on a control ring 39 actuated by a lever 47 and link 51. The members 51, 65 are connected to the floating lever 53 of a differential linkage operated by push-pull rods 11, 12. Movement of the rod 11 results in bodily vertical movement of the lever 53, thereby applying equal pitch changes of the same sign to both rotors, while movement of the rod 12 causes tilting of the lever 53 about the point 54 to apply equal pitch changes of opposite sign to the rotors. The rudder bar or pedals are arranged to operate the three rods 12 equally in the same sense to create equal unbalanced reaction torques in the three rotor assemblies, fore-and-aft movement of the control column displaces the rods 11 to increase the lift of the forward rotor assembly and decrease that of the rear rotors, or conversely, while lateral movement of the control column displaces the rods 11 of the rear rotors to cause differential variations of their respective lifts. An additional control lever is provided for effecting simultaneous collective pitch control to all six individual rotors. Specification 616,227 is referred to.

Abstract: 1,270,246. Rolling mills. BRITISH IRON & STEEL RESEARCH ASSOCIATION. 11 June, 1969 [14 June, 1968], No. 28562/69. Heading B3M. [Also in Division G3]  A method of rolling stock other than sheet or plate in a continuous mill includes subjecting the stock to two passes so that it leaves the second pass with desired dimensions, the roll speed or gap of either or both of the passes being controlled in response to direct or indirect  measurement of the stock cross-section. In an example, Fig. 4, a width error is measured at 24 following the second stand and is used to control the roll speed of the second stand. The second stand is provided with a constant-gap system 61 or is of very stiff construction. The constant speed settings of the stands are not altered. In similar instances, both the width and height of the stock may be measured, the resulting error signals being used to control the speed or gap of one or both stands. In an example of a predictive system, Fig. 6A, error signals are fed forward to one or both stands to control their speed or gap settings. The measurements of width and height of the stock can be used for updating the coefficients in equations relating to the stand parameters, to enable speed or gap-setting changes to be predicted. Instead of making direct measurements of the stock dimensions, indirect measurements may be made. Thus the stock height can be derived from the no-load roll gap and mill spring values of a stand, and the width from the height and from mass flow values of the stock. Fig. 3 illustrates diagrammatically how height and width error measurements 25 and 26 vary the gap of stand 21. The measurements are modified by resistors 12, 13, 16, and 33 whose value is derived from equations relating to mill parameters. The output from a three term controller 34 is fed to a constant-gap system 37 where it is combined with an error signal relating to the lower roll position. The combined output from an amplifier 46 is fed to a servo valve 28 controlling the roll gap.

Heading D1N In a rectilinear camber the detaching rollers 23 are driven by a differential gear 21 which has an input which receives both a reciprocating drive and a uniform drive. An eccentric 8 receives a non-uniform rotating movement through a pull rod 10 from a crank pin 5 movable at a constant speed about circular camb shaft 1 which is off-set relative to the centre of rotation of the eccentric. The eccentric supports a rocker 11 pivotally connected with a supporting lever 14 which is rotatably mounted on a nipper drive spindle 22, the rocker acting through a link 16 to transmit the movement imparted to it by the rocker 11 to a control lever 17 fixed to shaft 20 of the differential gear. The pull rod 10 is driven off the camb shaft 1 through an angularly adjustable wheel 4 which supports the crank pin 5, the effective length of the pull red being adjustable. The rocker 11 is pivotally connected to link 16 at a point diametrically opposite to the pivot 15 of the supporting lever. The uniform drive is transmitted to the differential gear from the shaft 1 by gear wheels 27, 28, a link 30' connected to a planet wheel 32 and via a further wheel 32' and sun wheel 33 mounted on shaft 20.

A machine, for perforating a record-card having a plurality of multicolumnar decks of data-receiving positions arranged one deck above the other, comprises a row of punches, a row of sensing elements, a carriage supporting record card and a prepunched pattern card, means to control the stepping of the carriage to cause the record card to traverse the row of punches and the pattern card to traverse the row of sensing elements, mechanism for moving the carriage, a set of character-representing keys, devices responsive to the operation of any selected key cause punches to effect perforations, representative of the selected key, in a column of one of the decks and devices controlled jointly by the sensing elements and the carriage-stepping control means for causing the punches to perforate in the same column of the remaining decks in duplication of data in the corresponding positions in the pattern card. The punches 85, Figs. 11 and 36, are arranged in a row containing twenty-one individual punches spaced to correspond to the punching positions of the three decks A, B, C shown in Fig. 38. Each punch is slotted at its upper end to receive the end of a lever 112 pivoted at 113 and an interposer 114 is pivoted at 115 to lever 112 and normally occupies the position shown in Fig. 11. The interposer has a slot 116 into which extends a pin 117 of a lever 118 pivoted at 118a. Punchselecting magnet 120, when energized by depression of an appropriate key, attracts its armature 121 and through link 122 rocks lever 118 to the position shown in Fig. 36 so that upon descent of punch-bar 123 the latter will engage a shoulder on the interposer and operate the punch. The punch is retracted by the upward movement of a restoring bar 127 which reciprocates with the punch-bar 123. In punching a card as shown in Fig. 38, the card is traversed past a column of twenty-one punches, the " key punch " columns in deck A only being punched by operation of a keyboard. At the same time the three decks A, B and C of the pattern card are sensed simultaneously by a bank of twentyone sensing wheels so that the " Duplicate " columns in the three decks are punched during this first movement or " pass " of the card past the punches. The carriage is then returned automatically to allow of key punching the relevant columns in deck B and again returned for key-punching in deck C, after which the card is automatically ejected and a fresh card is fed from a hopper to the carriage. Punching in decks D and E is effected by inserting the card upside down and face down in the machine, the coding then being changed, by a manuallyoperated switch, so that the card may have the correct hole-combinations punched therein.

Abstract: 1,274,062. Wrapping stacks of sheets. SOC. PER AZ. WRAPMATIC. 6 June, 1969 [11 June, 1968], No. 28723/69. Heading B8C. A stack of paper sheets is drawn, while lying on a sheet of wrapping paper, to a wrapping station at which one edge of the wrapping paper is folded over the stack by an endless belt moving in the manner of a caterpillar track. When a stack 23 on a feed conveyer 10 strikes a transverse stop (22), Fig. 1 (not shown), a pusher 30 (Figs. 2 and 5) moves the stack to a position in which it overlaps the leading end (Fig. 2) of a web 33 of wrapping paper supplied from a reel 34. The stack and the wrapping paper are then gripped by pincers 45b (Fig. 5) which move in a channel 45c. The stack is thus moved to its Fig. 3 position in which it rests on rollers 118 and on the top of the rear end of a stationary conveyer belt 116. The wrapping paper which has been drawn with the stack is cut by a device 3. A stop 109, which was previously below the level of the stack 23, is raised to fold up the leading edge of the wrapping paper. A unit 56 including an endless belt 60 mounted on rollers is lifted to fold up the trailing part of the wrapping paper and is then moved to the left, as seen in Fig. 3, so that the belt 60 moves over the stack in the manner of a caterpillar track to lay the wrapping paper on top of the stack. While the belt 60 remains on top of the stack, the belts 60 and 116 are motivated so that together they force the stack beneath the stop 109 which acts to lay the leading end of the wrapping paper on to the top of the stack. The belt 116 carries the stack to devices 124 and 125 which complete the wrapping. The unit 56 slides on guide rods (54, 55), Fig. 4 (not shown), which are raised and lowered to provide the vertical movement of the belt 60.
