Abstract: 943,230. Ratchet gearing; screw and nut gearing. ROTORK ENGINEERING CO. Ltd. July 28, 1961 [July 28, 1960], No. 26231/60. Headings F2Q and F2X. A servo-mechanism comprises a motor, the unidirectional rotation of which is translated into two-way movement for opening or closing a valve or other apparatus in accordance with a signal supplied to the translating means. A continuously running motor 10 reciprocates a connecting rod 11 by an eccentric mounted on the spindle 12, the connecting rod oscillating a lever 14 extending substantially radially across the wall 15 of an output drum 16 to a pivot 22. The pivot 22 is carried by a U-shaped rod 23 moved substantially along a diameter of the drum 16 by the action of solenoids 30, 31 against a centring spring 28. The solenoids are energized to move the pivot 22 in one direction or the other to move the lever 14 from a radial position and allow friction rollers or pads 19, 20 to grip the wall 15 and rotate the drum 16 to move a threaded valve spindle 18 to open or close the controlled valve. Energizing current is supplied from a change-over switch 30A, 31A actuated from a balanced arm 38 acted upon by a force balanced motor 37 receiving a control signal from input 35, 36, and by a mechanical feedback spring 40 connected to the valve spindle 18. Torque or limit switches may be included in the solenoid circuit and the actuator may be made to " fail safe " by the use of a flywheel on the shaft 12 and a generator driven by that shaft to continue energization of an open or close solenoid should the control current fail. The Provisional Specification describes alternative forms of ratchet gearing employing wrapping band clutches.

Metal-working presses.- A relief-mechanism for use in pressing, punching, shearing, forging or like machines comprises one or more rows of edge-pressure plates d or links q of the kind described in Specification 180,709 arranged between the machine table a and a, yielding member f which is connected through a further series of pressure plates to a stationary base-plate c<1> secured to the machine framing. Lateral movement of the member f to permit the descent of the table when excessive load is applied is resisted by a spring g which is adjustable by a screw h coacting with a setting-scale p. The initial inclination of the pressure plates is determined by an abutment l which carries a graduated rod o and is axially adjustable by a screw n operated from a handwheel n<1>. In a modification, Fig. 2, the lower series of pressure-plates are replaced by rollers e arranged as described in Specification 196,331, or balls may be used instead of rollers. In a further modification, the spring g acts through a pivoted lever to resist the movement of the plate f. In another modification, Fig. 3, the plate f is connected to the ram s of a fluid pressure device, the yielding pressure being determined by a spring t' adjustable by a rod h and acting through a lever t<3> on a second ram t. The table a may be T-slotted to receive dies, punches, shear blades, or croppers, or forging, swaging, embossing or other tools.

Title: Blow-moulding of containers
IPC: B29C49/50
Filed: 1971-04-19
Abstract: 1354364 Blow-moulding CONDUCO AG 19 April 1971 [28 April 1970 9 Dec 1970] 26424/71 Heading B5A In a blow moulding process the excess material above the neck portion of the container is engaged by a sleeve on the blowing mandrel and is separated from the neck portion by movement of the sleeve relative to the mandrel. A spring- loaded sleeve 3, Figs. 3 and 4, on the blowing and neck shaping mandrel 2 has a parison cutting edge and has teeth or projections where it enters the hot parison. A pin extends from the mandrel into a helical slot 18 in the sleeve, to effect slight rotation of the sleeve to separate the excess material from the neck portion of the container. A cooling of the neck and excess portions is effected before withdrawal of the mandrel. As the mandrel is withdrawn from the container the spring 10 moves the sleeve 3 downwardly to push the container off the mandrel and on continued upward movement of the mandrel the excess material is pushed off the sleeve 3 by a plate 21 and is deflected by a baffle 23 out of the path of movement of the container. In a modification, Fig. 5 (not shown), the sleeve 3 comprises two telescoping parts. In the embodiment shown in Fig. 6 a sleeve 37, 38 surrounds the mandrel 34 and has at one end a cutting sleeve 39 and at the other end a cylindrical chamber 47 closed by a cap 43. A spring-loaded piston 41 rigid with the mandrel is located in the chamber 47. A sleeve 50 surrounds the sleeve 37, 38 and has a bottom conical end 52 which has projections or teeth into which the excess portion of the parison is forced and set by cooling of the excess and of the neck portion. On withdrawal of the mandrel pressure fluid is admitted into chamber 47 to effect downward movement of the sleeve 37, 38 and the cutting sleeve pushes the container off the mandrel, the excess material being held on the conical part 52 of the sleeve 50. On release of the pressure in chamber 47 the sleeve 50 moves up with the mandrel and the excess material is stripped from the sleeve by the plate 56 and deflected away from the path of movement of the container. Slight rotation of the sleeve 50 with respect to the mandrel may again be provided for as in the first embodiment. In a final embodiment, Fig. 4, the end 62 of the mandrel 61 has fixed thereto a cutting sleeve 63 and a spring-loaded sleeve 71 the lower end of which has projection or teeth. The sleeve 71 has a flange 70 which is connected by tie rods 69 to a crosshead 67 connected to the mandrel. On opening of the mould a slight downward movement of the mandrel with respect to the sleeve 71 separates the excess material, which in this embodiment includes wing portions, from the container. On upward movement of the mandrel the container is dislodged by the plate 80 and the excess material by the plate 79.

Within the P(N) type region 24 an N(P) type region 28 is diffused so as to define with the region 24 a PN junction which is reverse biased by a control voltage applied to the gate of the IGFET. The regions 24, 28 effectively constitute the base and emitter of a groundedcollector bipolar transistor 18, the emitter-base junction of which behaves as a zener diode voltage regulator for the gate of the IGFET 16. In the embodiment shown two such regulators 18, 20 are arranged in series. A diffused resistor 14 serves to limit the current to the emitterbase junctions of the devices 18, 20 and to the gate of the IGFET 16, and in a modification particularly sintered to the case where many IGFETs are provided with their gates in parallel, the current limiting resistor (54), Fig. 4 (not shown), is situated so as the limit only the current through the control voltage regulating devices (58, 60).
