Title: Improvements in or relating to means for effecting a temporary coupling between fluid delivery means and fluid receiving means
IPC: F16N21/04
Filed: 1943-05-12
Abstract: 568,945. Pipe couplings. NEUMAN, C. J. May 12, 1943, No. 7556. [Class 99 (i)] A coupling member 1, adapted to be automatically engaged by and retained on a nipple 22, is of the kind having a spring-pressed plunger 8 carrying a seat for the nipple and spring-pressed locking jaws 26 which engage a groove 24 in the nipple, and is adapted to be disengaged by a slewing movement. A cap 29 screwing on to the casing 1 has screwed into it a ring 31 which retains the plunger in the casing and the jaws in the cap so that they move only radially. Each jaw comprises three segments of which the middle segment 33, Fig. 3, is offset circumferentially with respect to the outer segments 35 so that it can engage in the recess 34 of an adjacent jaw. The segment 33 projects inwardly beyond the segments 35 and has both edges 36 chamfered to permit automatic engagement and disengagement of the nipple. A coiled spring 40 in an outer groove of the jaws is of elliptical cross-section with its major axis normal to the axis of the coupling. The nipple which is of the construction described in Specification 568,976 has a hemispherical head engaging a conical seat 18 in the plunger which may have a conical projection engaging the bore of the nipple.

Title: Melt spinning of isotactic polypropylene
Inventor: BENSON RICHARD WILLIAM HAROLD
IPC: D01D5/23
Filed: 1962-02-27
Abstract: 964,406. Spinning polypropylene. IMPERIAL CHEMICAL INDUSTRIES Ltd. Feb. 18, 1963 [Feb. 27, 1962], No. 7636/62. Heading B5B. Isotactic polypropylene filaments having a spontaneously developed helically crimped form are produced by melt spinning the polymer at such a temperature and at such a throughput and the intrinsic viscosity of the polymer being such that the intrinsic viscosity of the spun yarn is in the range 1.0 to 3.0, preferably 1.5 to 2.5, and that the birefringence of the spun yarn is between 10 x 10<SP>-3</SP> and 25 x 10<SP>-3</SP> and thereafter allowing the yarn to relax freely. The spun yarn may be drawn 1.2 to 4.0 times its original length before being allowed to relax. The stretched yarn thereafter being allowed to relax freely and quickly. The polymer before melt spinning may have an intrinsic viscosity between 1.0 and 6.0. The spinning temperature may be between 165 C. and 320 C. The relaxed helically crimped yarn may be maintained in the relaxed state at 100 to 140 C. for a further period of, for example, 20 minutes, to stabilize the crimp. When a drawing step is used the temperature of the heated pin, roller or other device whereon drawing takes place may be adjusted to a temperature within the range about 10 C. to about 140 C. The preferred drawing temperature is within the range of about 80 C. to about 100 C. Specifications 810,023 and 818,100 are referred to.
Patent GB-200869-A (GB)
Title: Improvements relating to the control of turbine driven electrically operated winding plant and the like
IPC: F01D17/00
Filed: 1922-03-16
Abstract: 200,869. Stubbs, A., and Metropolitan- Vickers Electrical Co., Ltd. March 16, 1922. Regulating.-Power plant subject to cyclic variations in load is controlled so that the variations in power output of the prime mover are kept within limits which are less than those corresponding to the variations in load during a succession of similar cyclic variations in load, but the torque or power output is varied automatically to suit the new conditions in the event of any load variation beyond the limits of the normal cyclic variations which would necessitate an increase or decrease in the average power output of the prime mover. Fig. 1 shows one construction in which the fluid supply valve of a prime mover has a slow selfclosing movement and is controlled by a governor through a lost-motion device. so that in the event of the speed of the. plant falling below a predetermined limit the self-closing movement is arrested, whereas in the event of excessive speed the closing movement is expedited. The fluid-supply valve 3 of the prime mover tends to be closed by a spring 6. When the prime mover is at rest, a rod 19 connected to a speed governor (not shown) maintains a piston 10 at the bottom of its stroke and thus through links 9, 12 maintains a valve 5 in position to supply fluid pressure to the underside of a piston in a cylinder 4, to open the valve 3 upon the operation of a starting cook or the like. Opening of the valve 3 moves the valve 5 to close the cylinder 4, the pressure in which then maintains the valve 3 in the open position. As the engine! speeds up, the governor raises the rod 19 and gradually releases the piston 10, so as to open the valve 5 gradually to exhaust and thus allow the spring 6 to impart a slow selfclosing movement to the valve 3. If the speed of the plant decreases, the rod 19 falls and by means of the projection 22 first closes the valve 5 to exhaust and arrests the closing movement of valve 3, and if necessary then re-positions the valve 5 for re-opening the valve 3. In the event of dangerous overspeeding, the projection 20 raises the valve 17, releases the pressure in the cylinder and allows the spring 14 to raise the piston 10 rapidly until the valve 5 is open fully to exhaust. Continued overspeed after this operation results in the lever 23 being raised, thereby operating another valve and piston to manipulate a rheostat 28 to apply a braking force to the motor. In a modified construction the rod 9 has a double-spring connection with the governor.

Title: Belt retractor with winding prevention mechanism
IPC: B60R22/44
Filed: 1976-02-27
Abstract: 1501052 Seat-belt retractors GENERAL MOTORS CORP 27 Feb 1976 [28 March 1975 16 June 1975] 07865/76 Heading A3V In a vehicle-sensitive seat-belt retractor the reel 26 can be locked against rewinding so as to give the belt a set degree of slackness by a detent mechanism such as a ratchet and pawl device 88, 126 which is so controlled by means 92, 108 responsive to rotation of the reel that after the detent mechanism has initially been actuated the belt may be unwound through a predetermined range of rotation of the reel within which the detent mechanism is released only temporarily and is able to lock the reel again automatically when the belt is wound in and the reel rotates (in its winding direction) beyond said range but if the reel is rotated beyond said range in the unwinding direction the detent mechanism is permanently released (until reset) and the belt can be wound in completely. The control means comprises a control disc 92 and a blocking disc 108 freely mounted on the reel shaft but frictionally coupled for limited rotation therewith. On initial belt withdrawal pawl 126 is lifted to release position by successive portions 105, 100, 102, 103 of the control disc until a projection 104 abuts an edge 120 of the blocking disc, itself arrested by a stop 116, to arrest the control disc. Subsequent winding of the belt to its occupant-restraint position lodges the pawl 126 in a notch 118 of the blocking disc and the control disc rotates fully to its Fig. 4 position. When the belt is now pulled out the pawl is allowed to leave notch 118 as the discs rotate clockwise towards stop 116 and enters a notch 106 of the control disc wherein it may lock with any one of several consecutive ratchet teeth to set the desired degree of slackness. If the user leans forward the pawl is lifted onto surface portion 100 whose length corresponds to said range of rotation and is able to engage the first ratchet tooth when the belt is rewound. If the belt is withdrawn beyond said range, however, the pawl rides up portion 102 and enters notch 118 so as to be permanently disabled. The retractor incorporates a locking pendulum mechanism 58.

Near the end of the movement of the plate 7, compressed air penetrates through a vent groove 7a in the plate to behind the sprue collar 5a and ejects the sprue from the die half 2.
