Abstract: 1,247,573. Bobbin feed device. J. GODDER IDGE. 17 Jan., 1969 [21 Feb., 1968], No. 2744/ 69 Heading D1F. A device for feeding an elongate element 3 on to a bobbin 15 comprises a rotary tensioning device 1 to tension the element, a rotary storage means 5 coaxial with the inclined axis of the tensioning means, a controllable brake 13, a frame 14 for the bobbin, a motor 20 to drive the bobbin, motor speed control means (not shown), and detection means 16, 16a, and 18, 18a (not shown) to sense the position of the element on the storage means and to control the motor speed control means in relation to said position. Device 5 comprises a metal cylinder which at its free end has an enlarged portion of frusto-conical form to prevent the turns 4 of the element slipping off. The apparatus also includes an anti-ballooning device 10. When the feed on to bobbin 15 is too slow the amount of the element stored on device 5 increases until the part 19 of a turn 4 intersects the light beam passing between lamp 16a and cell 18a, whereupon the latter causes the control means to increase the speed of the motor. When the feed speed is too high the beam between lamp 16 and cell 18 is intersected by a turn 4 moving up device 5 causing the speed of the motor to be reduced.

Title: Pressure regulator valves
IPC: G05D16/10
Filed: 1973-01-19
Abstract: 1412171 Valves R MEHOUDAR 19 Jan 1973 [9 Feb 1972] 2913/73 Heading F2V A pressure regulating valve comprises a valve sleeve 8, Fig. 1, coupled to a pressure-displaceable actuating diaphragm, bellows or, as shown, piston 14. The sleeve is biased towards its open position by a spring 19 but moves towards seating 22 when the supply pressure exceeds a predetermined maximum value, to thereby adjustably throttle the flow path through the valve and prevent the outlet pressure from exceeding a desired maximum value. The arrangement is such that when the valve is closed the end 10 of the sleeve abuts the seating 22 with line contact having a diameter substantially equal to that of the cylindrical guide surface offered by a narrow annular flange 6a. The flange may include a flexible seal ring and the basic form of the valve housing may be that of a straight cylinder, Fig. 2 (not shown), or an elbow, Fig. 3 (not shown). The piston may be located in a chamber isolated from the main flow and communicated via an external conduit with downstream pressure. The piston may be connected to the sleeve through a flexible rod or one formed to permit limited relative angular movement. In Fig. 4 (not shown), a flexible shaft (78) attached to the piston passes through a wall defining a closed space above the piston such that movement of the sleeve is damped by restricted air leakage along the shaft. For large flow rates the valve housing may contain four regulating valve units similar to the one shown in Fig. 1 to collectively control flow from a common inlet to a common outlet, the valve units being removably mounted in the housing, Fig. 5 (not shown). A filter may be provided upstream of the throttle (Figs. 3 and 5).

[Classes 83 (i) and 83 (ii)] In joining parts by casting molten material, at a lower temperature than their melting point, about them, using a jacketed mould which is preheated by inserting hot material in the jacket. In joining lead covered cables 21, 22 these are positioned, opened up and the sheaths cleaned. A leaden sleeve 23 and discs 24, 25 of lead, having holes to correspond to the cables, are threaded thereon and the discs are soldered to the cables. Tape 27 is wrapped around the sheath ends, the conducting wires are joined and wrapped in dry muslin 28 and the sheath 23 is slid over the discs and its ends beaten into grooves 26 therein. After cleaning, one end of the box so formed is enclosed in a mould made up of a split cylinder 37 Fig. 10, adapted at 46 to fit the largest size of sheath it is proposed to join, and at 52 to receive a split disc 56 Fig. 13, or 57 Fig. 15, having one or two holes to correspond to sheaths of cables to be joined. For smaller sizes of cables divided sleeves 54 are inserted in these holes and at 46. The mould halves 37 have a gate 45, an external jacket, adapted to be filled, before pouring, with the same or another molten metal, and holes 53 to allow this metal to contact with the half discs 56, 57. Tin lead eutectic alloy is poured in and allowed to cool, then the mould is removed, and the gate metal 32, Fig. 3, is cut off. The other end of the box is then treated in the same way to form the cast ends 31. If a number of cables are to be joined in one splice a leaden disc, identical with the disc 25 is used in place of the split disc 57 and is threaded on the cable ends before the disc 25. This disc becomes incorporated in the cast joint. A thin tubular sleeve is also used to cover the openings 53 and prevent the jacket metal from being fused to the joint. A dead end may be cast on a cable by using a hollow plug in the innermost bushing.

Abstract: 175,277. Urbain, E., and Scal, C. Feb. 8, 1921, [Convention date]. Addition to 165,095. Void [Published under Sect. 91 of the Act]. Systems, electric.-In systems in which a magneto charges a condenser which is subsequently discharged through the primary winding of an induction coil, the connections between the magneto and condenser and the condenser and coil being alternately broken, the arrangement is such that the discharge through the coil traverses only one pair of contacts, instead of two pairs as described in the parent Specification and shown in Fig. 1. As shown in Fig. 2, the cam C actuates successively two levers A, B. The separation of the lever A from the contact Pm removes the magneto short-circuit and allows the condenser to be charged; the separation of the lever B from contact Pf breaks the magnetocondenser connection, and the contact between the lever B and contact P<11>m causes the condenser to be discharged through the coil. In a modification, the two pairs of contacts P are placed diametrically opposite with reference to the centre of the cam C.
