Title: Method and apparatus for the manufacture of continuous coupling elements for sliding clasp fasteners
IPC: A44B19/10
Filed: 1974-12-30
Abstract: 1482270 Continuous coupling elements for sliding clasp fasteners YOSHIDA KOGYO KK 30 Dec 1974 [29 Dec 1973] 55986/74 Heading E2S The invention relates to a method of manufacturing a continuous coupling element of folded meandering type having a series of U-shaped transverse portions each comprising a head at one end and a pair of legs extending from the head toward the other end and where the legs are connected by a series of longitudinal connective portions each of which interconnect the adjacent U-shaped portions and which are to be alternately arranged on the opposite sides of a stringer tape. According to the invention, the method comprises providing a blank strip 10 of sheet like material, alternately forming transverse cuts 12 of predetermined length in the blank strip from its opposite sides to provide a continuous rod like member 13 of zig-zag configuration, reshaping the rod like member into flat meandering configuration 14 such that the major transverse portions of the rod like member are arranged parallel to each other with predetermined longitudinal spacings, applying pressure centrally to each transverse portion to form lateral protuberances 15 which are necessary to provide a coupling head of the coupling element, and bending the transverse portions into the shape of a "U" to form the folded meandering type configuration. As shown, the blank strip of sheet like material, such as thermoplastic synthetic resin, of a suitable width and thickness, is indexed forward along a linear path over a base frame 20, Fig. 4, to succeedingly pass through a cutting mechanism 21 comprising a pair of rotary cutters, Fig. 4, which are driven out of phase and arranged on opposite sides of the strip; a forming mechanism comprising single and double prong dies 27, 28 respectively which are reciprocal toward, and away from each other to reform the zig-zag rod-like member 13 into meandering shape; and a vertically-reciprocable punch 23 to deform the lateral protruberances 15 centrally of the transverse portions. The member 13 then proceeds to a bending member 24 which includes an upright U-shaped guide channel 31 and a toothed wheel 32 which is fixed to a shaft 33 which is rotatable in step with the indexed movement of the member 14 to force the latter into, and through, the guide channel 31 and bend it into "U" shape. When the blank strip 10 is made of thermoplastic synthetic resin the cutting and forming mechanisms 21, 22, and the punch 23 may be heated. The bending, and punching, operations can be carried out simultaneously.

Title: Servo-control apparatus
IPC: F15B20/00
Filed: 1971-12-09
Abstract: 1372376 Servo-positioning apparatus; MOOG Inc 9 Dec 1971 [29 Jan 1971] 57151/71 Headings G3P and G3R Lever 38 operating a control surface of an aircraft is moved by three similar independent retroactive position control servosystems, Fig. 11; Figs. 11A, 11B (not shown), having no interconnecton between them, each having an equalizing feedback loop including unit 42 having an input/output characteristic, Fig. 15, with hysteresis to ensure load sharing by the actuators 31 (31a, 31b). Position control system. At summing junction 21, command signal 20 is combined with actual position feedback signal 41 derived from a linear differential transformer 40 connected to the output shaft 39 of actuator 31 to provide a normal position error signal 22, which in turn is combined at junction 23 with an equalization voltage 48, LVDT, Fig. 15, dirived from a linear differential transformer 46 coupled to output member 45 of equalizer 42, in dependence upon the differential pressure between fluid lines 43, 44. The resultant signal 24, via amplifier 25 controls the torque motor of an electro-hydraulic flow control valve 28 controlling piston 33 of actuator 31. Hydraulic equalizer 42, Fig. 12 Pistons 59 60 are biased apart by preloaded spring 61, and pressure differential between lines 43, 44 provides thrust on both pistons in the same sense, depending on the sign of pressure differential. Output shaft 76, provided with friction packing 91 between glands 92, 93 is provided with collars 82, 83, 84 around which fluid can pass freely, and such that, in the absence of pressure, collars 82, 84 engage surfaces 63, 85, collar 83 being equidistant between surfaces 67, 89, (whose spacing represents twice the lost motion of the equalizer), of the respective pistons. As pressure differential increases, in either sense, no motion takes place until spring preload is overcome B59, or B60 Fig. 15, whence one or other piston moves inwardly without movement of shaft 76, until collar 83 engages it B59-L59 B60-L60, followed by movement of the piston and output shaft 76, L59-P59 or L60-P60. Subsequent reduction of pressure differential causes no output shaft movement until collar 84, or 82 is engaged by the piston, P59-E59 or P60-F60, hence providing a hysteresis characteristic. Electric equalizer, Fig. 16 (not shown). Pressure transducer (95) provides an output voltage proportional to the pressure differential, which is fed to hysteresis circuit (96) including anti-parallel diode pair (101) and integrator (100) to output a parallelogram form hysteresis characteristic, which, after passage through threshold circuit (97) including anti-parallel diode pair (104) provides a hysteresis characteristic (e,#P) Fig. 16A (not shown) having substantially the form of Fig. 15. The output of equalizer 42 may be mechanically applied to servovalve 28, and it can be responsive to the actuator force, derived from a strain gauge in the load drive.

Patent GB-735165-A (GB)
Abstract: 735,165. Hydraulic apparatus. BERNTSEN, T. Nov. 12, 1953 [Nov. 12, 1952], No. 31415/63. Class 69 (2). Hydraulic apparatus, for lifting sliding shuttering used in making concrete structures, comprises a number of lifting devices, each having a ratchet operated lifting- screw, operated by fluid-pressure and controlled by electric or fluidactuated circuits which reverse the fluid flow to a piston and cylinder operating the ratchet. The control circuits are not complete until the ratchet arm of each lifting device reaches one extreme position and operates a switch, thereby ensuring that all the lifting devices remain in step. Each lifting-screw 3 is raised by a ratchet 40 advanced by an arm 8 attached to a movablecylinder 9 supplied with fluid from pipes 47, 48 connected, through a valve 18, to a pump 15. A piston 10 held between guides 51, 52 cooperates with the cylinder. The valve 18 is controlled by circuits I, II in which are switches 12 arranged on the ratchet mechanism of each lifting device. When all the arms 8 are in one extreme position, one of the circuits is completed and one of two electromagnets 32, 33 is energized and the valve 18 is pulled over to reverse the fluid flow and operate the ratchet in creases with increased turbine speed. The ports 56, 60 in the housing 54 and sleeve 58 are rectangular and the top of the plunger is flat so that the valve opening is a function of the product of compressor inlet pressure and turbine speed. The by-pass valve 98 is actuated by a diaphragm 106 subject on its lower face, by way of a passage 108, to the pressure before the valve 50, and on its upper face to the pressure the opposite direction. Visible or audible signal means 13 are provided in the control circuits. When the limit of the lifting screws has been reached, a switch is tripped and the motor and pump stopped. In a modification, the arm 8 is connected to the piston 10 which is movable, and the cylinder is stationary. The piston may be moved in one direction by air pressure and returned by a spring. In a further modification, the control circuits are fluidoperated (Fig. 10, not shown), or the lifting circuits may be hydraulic and the control circuits pneumatic, or both these circuits may be pneumatic. When the control circuit is fluid-operated, the switches 12 are replaced by valves 83 having a projection 89 at each end engaging a part 90 at each end of the stroke of the cylinder whereby a member 87 is moved to uncover ports 85, 86 and connect the supply from the previous valve to the next valve in the circuit.
