Abstract: 382,106. Bobbin cradles and stop apparatus for drum winding-machines. HIGGINSON, J. and ARUNDEL, COULTHARD, & CO, Ltd., Sovereign Works, Stockport. Nov. 27, 1931, No. 32903. [Class 120 (ii).] In a drum winding-machine of the type in which the bobbins i being wound are maintained in contact with the driving drum h by spring means and in which, when an end breaks, a stop-motion operates through spring- assisted means to cause the bobbin cradle b to fall and bring the bobbin on to a brake j which is raised towards the bobbin, one or more springs a are provided at each winding head, each spring serving not only to lower the hand-lever e and cradle b when knock-off occurs so as to press the bobbin i on to the brake j, but also to bring the cradle with its bobbin against the drum h when the hand-lever is raised to start winding, and to maintain the bobbin against the drum during winding. Each spring a is connected to the cradle b at c below d the pivot on the hand-lever e, and adjustably to the bracket f which is itself adjustable on the bracket g. The brake j is pivoted at k and rests on an inclined member m pivoted at n on the cradle b and supported by an adjustable stop o. The cradle b is connected by an arm p and rods q to the cylinder r of a plunger type dashpot which offers resistance to upward movement of the cylinder only. The rod t of the plunger s is pivotally secured to the bracket g, and the cylinder r moves freely over the plunger s when the hand-lever e and cradle b are lowered and as the cradle moves away from the drum h during building-up of the bobbin i. When the cradle has moved away to its full extent the bottom end engages a catch u. When the hand-lever e is raised and the cradle released from the catch u the springs a move the cradle towards the winding drum against the resistance of the dashpot. A stop v is provided to limit the upward movement of the hand-lever e. To permit of more easy operation, an auxiliary hand-lever w may be pivoted at w<1> on the lever e and arranged to bear by its end w<2> on the surface x. The lever e is supported during winding by the arm z of the detector box.

Title: Improvements in or relating to the production of semiconductive material
IPC: C30B31/06
Filed: 1960-09-26
Abstract: 904,806. Semi-conductor materials. TELEGRAPH CONDENSER CO. Ltd. (Sprague Electric Co.). Sept. 26, 1960, No. 33027/60. Class 37. In a method of vapour diffusing an unpurity into semi-conductor substrate a source of the impurity in liquid form which also constitutes a vacuum-tight seal for the chamber containing the substrate is heated to vaporize the impurity into the chamber. In a preferred embodiment liquid indium 15 is diffused into germanium body 11. Initially cup 14 mounted on rod 16 is lowered clear of the mouth of the upper section 10 of the vacuum chamber and the latter exhausted through vent 13. When the required degree of vacuum is obtained the cup is raised into the position shown so that the indium, maintained molten by radiated heat from jacket 20, seals off the upper section of the chamber. The germanium is then raised to 750-900 C. and the indium to 500-750 C. by heaters 21, 22, respectively, to diffuse indium into the germanium. Movement of rod 16 is effected by movable magnets 18 co-operating with an armature 17 attached to the rod. During diffusion the indium scavenges impurities already present in the chamber and any which are driven out of the germanium. Gallium may be used instead of indium but where other impurities are to be diffused into germanium or silicon the diffusant is used in the form of an alloy with indium.

Abstract: 1524673 Centrifugal governor; fluid-pressure servomotor systems CAV Ltd 17 July 1975 [26 July 1974] 33029/74 Headings G3B and G3P The governor weight mechanism 43 of fuel injection pumping apparatus Fig. 1 has flyweights 61, Fig. 2, pivoted on a reaction member 62 which is supported in opposition to the governor spring 49 Fig. 1, by a resilient means, e.g. spring 67, Fig. 2, there being a dash-pot 66, 68, to limit the movement rate of the reaction member when the governor spring load is increased. Fuel supply to the injection pump is timed by valves 20, 22, 23, 24 in member 10 and is supplied from a feedpump 25, quantity being limited by the position of a shuttle 19 controlled by a piston 35 as determined by the position of a rod 41. The rod with weight mechanism 43 and spring 49 form a governor, manually settable by an abutment 51. The rod is positioned arially in balance between the centrifugal action of the weights and fluid reaction between it and a valve-member 48 so that flow to the injection pump is further controlled by cooperation between rod 41 and a metering port 55. Injection pump timing is controlled by movement of a servopiston 39 attached to the cam ring 13. The piston 39 follows the valve 38 which moves in response to the difference between pressures applied at its ends respectively from the feedpump and via conduit 45 from a port controlled by the rod 41.

Abstract: 456,084. Amalgamators. DVORZSAK, H., Kremnica, and VALENTENYI, A., Yyhne, both in Czecho Slovakia, and KACHELMANN, K., 92, Baross Utca, Ujpest, Hungary. Dec. 2, 1935, No. 33401. [Class 82 (ii)] An amalgamator in which the amalgam plates are arranged to form a drum rotatable about a horizontal shaft in a closed housing is constructed so that the slime flows in a zigzag path through a series of flow channels of annular form. A housing 1 is closed by end plates 2, 3, the end plate 2 having an opening connected to a hopper 26 and the end plate 3 having a door 4. A shaft 13 passing through the housing carries a spider 15 with arms 28 and also a disc 14, the hub of which is constructed to form an inlet opening 25. A disc 16 made in two parts is fixed at the middle to the spider 15 and at its periphery to the arms 28. Bars 17 extend between the disc 14 and the arms 28 and are formed with slots into which amalgam plates 18, which may be silver-plated copper sheets coated with mercury, can be introduced. The plates 18 which form a series of annular flow channels 32 do not extend the whole distance between the discs 14 and 16, spaces 30 being left so that the slime can pass from one channel to the next with reversal of its direction of flow. The channels are preferably formed so that the velocity of flow decreases as the slime flows outwardly from the central channel to which it is introduced from the hopper 26 through the opening 25 in the hub of the disc 14. Mercury is also introduced into the central channel by a pipe 11. The outer plates 18 extend from the disc 14 to the disc 16 and are provided with openings so that the slime is discharged radially into the housing. Stirring vanes 21 are provided on the discs 14, 16 and stirring angles 22 on the arms 28. One side of the housing is provided with a drain opening 5 which can be closed and the other side is constructed to form a chamber 6 in which amalgam is collected. A spray pipe 7 is provided in this chamber to prevent settling of the slime and the upper end of the chamber is constructed as a discharge gutter 8 for the slime. An elbow-piece 8a connects the top of the housing with the feed hopper 26 to return any surplus slime, which cannot escape through the gutter 8, to the hopper. Each of the prisms formed by a series of individual plates 18 may be replaced by a single plate of any desired crosssection, e.g. by a cylindrical plate.
