Title: Method for exchange of full bobbins for empty ones on textile  machines and apparatus for carrying out this method
IPC: D01H4/48
Filed: 1973-02-20
Abstract: 1367283 Continuous winding VYZKUMNY USTAV BAVLNARSKY 20 Feb 1973 [21 Feb 1972] 8233/73 Heading D1J A continuous winding method in which the package 2 being wound is driven by a friction drive drum 1, Fig. 1, is characterized in that the new empty bobbin 2" is forced by a linkwork mechanism between the full bobbin 2', Fig. 2, and the driving drum 1 thus interrupting the direct contact of the full bobbin 2' with the drive drum 1 and causing the full bobbin 2' to reverse its direction of rotation. Continued motion of the linkwork, shown in heavy black lines, causes a roller 30 to move between the empty bobbin 2" and the full bobbin 2' to lift the full bobbin up and deposit it on a pair of beams 10, only one of which is shown in Fig. 1. The full bobbin 2' is normally carried by a cradle comprising a pair of arms 4. As the full bobbin 2' is raised by the roller 30 a pair of deflector plates 33 at the upper end of bars 32 force the arms 4 apart to release them from the full bobbin 2'. The arms 4 swing downwardly and strike two lower deflector plates 33 that again space the arms 4 apart in a manner permitting them to grip the empty bobbin 2". The apparatus of the invention is only in position at a particular winding unit when bobbin exchange is required. The yarn 3 starts to be wound at the contact place of the driving drum 1 with the empty bobbin 2". At the contact place of the empty bobbin 2" with the full bobbin 2' a part of the yarn freshly wound on this bobbin 2' is again wound off. This released yarn forms a loop which is immediately entrained between the drum 1 and the empty bobbin 2" to break the yarn between the empty and the full bobbin. The apparatus disclosed may be carried by a carriage 9 mounted on rollers 7, 8 moved along a guideway 6.

Title: Steering control system for a motor vehicle
IPC: B62D6/04
Filed: 1974-02-27
Abstract: 1426316 Automatic vehicle steering control. NISSAN MOTOR CO Ltd. 27 Feb 1974 [1 March 1973] 8839/74 Heading G3R A motor vehicle is automatically returned to a desired direction of travel following deviation, by a system responsive to the vehicle forward velocity and the transverse velocities of the two ends of the vehicle. Electrical signals representing the sensed velocities are used to compute a control signal for an automatic steering arrangement. As shown, a computing circuit 4 receives signals from velocity sensors 1, 2, 3 which may include Doppler devices, and calculates, using operational amplifiers as integrators, an electrical signal representing a distance by which the vehicle has deviated from a desired direction. This signal is fed through an amplifier 7 to a device 6 which controls an hydraulic steering actuator 60 such that the vehicle will be returned to its original direction. Both the automatic control device 6 and a manual steering control 10 are connected to the vehicle wheels through an over-ride device 8. The steering angle demanded by the driver is sensed 5, and a corresponding signal is fed to a logic circuit 9 together with the signal from the front end lateral speed sensor 1. These signals are compared with preset reference values, and the circuit 9 inhibits the operation of computing circuit 4 by shorting the integrating capacitors unless the demanded steering angle is less than a preset value and the lateral velocity is, at the same time, greater than a preset value. The circuit 4 may additionally include a yaw computing circuit and an optimum correction simulating circuit which has previously been suitably programmed.

Abstract: 243,963. Flanders, R. E. April 3, 1025. Chasers.-In a process of making chasers for screw - cutting die-heads &c. the chasers, after being threaded, are hardened at a temperature sufficiently high to produce distortion or fusion of the points of the threads, are then reduced to approximate form and are finally finished, preferably by lapping. In a modification the chasers may be hardened first, then threaded by grinding' and finally lapped. The grinding to approximate form is performed by a wheel 2, Fig. 1, of a diameter not less than three the chaser 1 being, (a) fed in the direction 3 to produce teeth having a concave profile, or (b) fed tangentially to the wheel to produce teeth having a straight profile, or (c) rotated about a centre outside the wheel to produce teeth having a slight convex profile. The lapping is performed by a soft steel threaded lap 5 charged with emery and having a diameter slight greater than that of the work 4 which is to be cut by the chaser. The action of the lap is to produce a concave cutting edge a, c, Fig. 4, to bear on the work.

Abstract: 736,893. Frequency-selective discharge tube amplifying circuits. STANDARD COIL PRODUCTS CO., Inc. March 31, 1953 [April 26, 1952], No. 8936/53. Class 40 (6). In a tuned amplifier of the type in which a signal is applied to a grounded grid valve 19, variations of response with changing grid bias due to variations in cathode potential are minimized by the use of a neutralizing network between the anode and cathode circuits. The amplifier is particularly for use in a television receiver where an A.G.C. voltage is applied to the valve 10, and results in a varying anodecathode capacity 55. The effect of this capacity is reduced by the use of a bridge comprising capacitors 31, 35 and 37, Fig. 2 (not shown). The two valves are coupled over an inductor 22 as described in the Specification 703,946 and the grid of valve 19 is biased by the network 45.

Abstract: 256,297. Webb, J. F. April 6, 1925. Sunken objects, indicating position of.-In safety apparatus for submarine vessels in which a float is released from the vessel and carries an air tube to the surface, the drum on which the tube is wound is enclosed in a watertight casing carried by a breech block which fit's the torpedo tube, from which the float is ejected. The tube also contains a cable by means of which signals may be given from the float. The float 4, Figs. 2 and 3, is shaped so as to be adapted for ejection from the torpedo tube, and comprises a copper shell 6 encased by wooden staves 7 secured by bands 36, 37. A rubber gasket 38 may be provided as an air seal when the float is ejected by compressed air. A conical protective nose 8 is fitted. A pipe 9 extends through the float, and is adapted at its lower end to make connection with the armoured hose 11. A bearing member 39, connected by chains 40 to the float, prevents flexing of the hose 11 at the junction. The upper end of the pipe 9 extends into the nose 8 and is provided with inwardly and outwardly opening check valves 12, 13 respectively. Inside the hose 11 are electric cables 14 leading from the submarine to signal lamps located behind screens 15 in the nose. The hose 11 is wound around and secured to a hollow reel 16, Fig. 5, the hollow trunnions 17 of which provide for the connection of the hose 11 to a reversible air pump 20 and for the connection of the electric cables. The reel 16 is mounted in an air tight housing 19, which is secured by a flange 24 to the flange 26 of a breech block 27. The latter has a passage way 32 for the hose, and is mounted as usual in a hinged frame 29 and provided with the usual mechanism for securing it to the torpedo tube. A hand brake 33 may be provided to control the paying out of the hose 11, and a revolution counter 34 for indicating the depth of the vessel when the float reaches the surface. A crank 35 may also be provided for reeling in the hose. In use, the torpedo tube is closed at the outer end, and the water drained therefrom and from the casing 19 by a drain cook. The breech block is then opened, and the float secured to the hose 11 and inserted into the torpedo tube. The breech block is then closed and the sea door opened, and the float is ejected by compressed air, or alternatively by an explosive charge or by hand. Before ejecting the float, air is forced by the pump 20 into the hose to render it more buoyant and to prevent entry of water. When the float reaches the surface, the action of the pump is reversed, and air is drawn down throuph the hose. By means of the electric cable, light signals or audible signals may be operated. Telephone connections may be provided on the float. The submarine vessel may be equipped with a pipe 44, Fig. 1, extending upwardly and provided with valves 47, 48, 49 at the upper end for the supply of fresh air.
