Title: A hydraulic system for controlling a regulator member in a fluid flowline
IPC: G05D16/18
Filed: 1957-12-18
Abstract: 869,546. Fluid-pressure servomotor control systems. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. Dec. 18, 1957 [Dec.26, 1956], No. 39375/57. Class 135. An hydraulic system for controlling a regulator member disposed in a fluid flow line comprises a first cylinder having an actuating piston therein connected to said regulator member, a second cylinder having a movable partition therein, a liquidfilled conduit interconnecting said first cylinder and said second cylinder for transmitting liquid pressure between one side of said partition and one face of said actuating piston, a source of liquid under pressure, means responsive to a variable factor such as liquid pressure or an engine speed effective to move said partition from neutral position in one or the other of two opposite directions, and valve means operable upon movement of said partition from said neutral position to connect said conduit either with said source or with the exhaust to thereby provide an additional operating pressure difference to operate the actuating piston and so cause additional movement of the actuating- piston over that which would be caused without this additional pressure difference. In the first example, Fig. 1, a spring-loaded piston 1 is subject to the pressure of a gas in a container 2 supplied from a pipe 3. Integral with the piston 1 is a differential piston 8 in a cylinder 9 connected by a conduit 11 to a cylinder 10 containing a piston 20 connected by a link 22 to a damper 23 in the pipe 3. A pressure supply is connected by pipes 15, 24 to both cylinders 9, 10. Upon movement of the piston 8 the pipe 24 is either connected to the conduit 11 via ports 13 and bore 12 or to an exhaust conduit 18 via ports 13, 19. The liquid in the conduit 11 acts as a fluid link between the pistons 8 and 20. In the second example, Fig. 2, the system is used to control a motor admission valve 25 in accordance with the speed of the motor 27. The conduit 48 provides the fluid link between the pistons 32 and 72. A speed governor 28 controls a valve member 30 to admit liquid under pressure to or exhaust it from a chamber 45. The resulting movement of the piston 32 actuates the double valve member 57 to connect the conduit 48 to a supply line 42 or to the exhaust line 21.

Title: Heating means for wire-drawing apparatus
IPC: H01B3/10
Filed: 1964-09-28
Abstract: <PICT:1057758/C1/1> Glass- or ceramic-sheathed metal wires are drawn by heating and stretching a glass or ceramic tube filled with metal, the heating being effected by passing the metal-filled tube through two super-imposed or consecutive heating zones, one a radiation heating zone and the other an induction heating zone.  In one embodiment, a metal-filled glass capillary tube 2 is inserted from above into a carbon tube 4 closed at both ends except for small passages 5.  A number of axially parallel slots 7 are provided in the wall 6 of the tube in a zone located in the lower half.  Electric current supply means 8, 9 are connected to the ends of the tube 4. At the level of the slots 7 the tube 4 is surrounded by an induction coil 10 wound from a copper tube through which flows a cooling fluid. The dimensions of the tube 4 are such that its internal temperature is not more than 500 DEG  C. below the lower limit of the softening range of the glass of the capillary tube, while the speed of the capillary tube is such that the metal filling reaches the temperature of the inside of the capillary tube before or as it enters the zone in which the wall of the tube 4 is slotted.  A high-frequency electromagnetic alternating field is generated in the induction coil 10 and passes through the slots 7 into the interior of the tube 4, giving rise to eddy currents in the metal filling of the capillary tube. The heat produced in the metal filling is sufficient to raise its temperature above the melting point of the metal or metal alloy and as this melting point is in or above the upper region of the softening range of the material of the capillary tube, heat is conducted from the metal filling to the capillary tube and the temperature of the latter raised until it exceeds the lower limit of the softening range.  In the zone of inductive heating, the capillary tube is drawn out together with the metal melt.  Both the glass cover and the initially still fluid metal core of the drawn wire commence to cool in the lower part of the tube 4 but by means of its radiant heat this part prevents over-rapid hardening of the drawn wire.  In an alternative embodiment, a cylinder of diamagnetic material surrounded by an induction coil is connected to an electrically heated tube, preferably of carbon, silicon carbide or graphite.  The metal of the metal-filled glass or ceramic tubes will normally be in the form of a wire but it is possible in cases where the metal has a lower melting point than the glass or ceramic sheath to employ a glass or ceramic tube filled with a metallic powder, which powder will sinter into a continuous body during the drawing operation. Alternatively, the tube may be separately heated before the drawing operation to provide a continuous metal core.

A switching device comprises an insulating shaft 12 supported at its ends in end-plates 5, 6 and having a number of diametral holes each containing a spring urging outwardly from the shaft surface a contact ball 14. The balls are retained by annular caps 13 and the other ends of the holes are obstructed by circlips 15. Each ball 14 operates within a circular V-section channel 45 surrounding the shaft, the channel being formed on one side by an annular contactring 11 and on the other side by a series of circularly-arranged contact blades 10 whereby as the shaft is rotated the ball successively connects the blades to the ring. Each circle of blades 10 is mounted in a series of radial slots formed in one face of a thick insulating ring 9a, a number of rings 9a, 11, together with thin insulating rings 9b, being stuck together by insulating varnish to form a cylindrical stack 8. As shown, the shaft 12 is driven step-by-step electromagnetically, the coil 7 lying between the plates 5, 6 parallel to the shaft, polepieces 15 at the coil ends co-operating with an armature 16. Pivot lugs 28 on the armature are held on knife edges formed on plates 27 by fingers 29 cooperating with further lugs 39. When the armature is attracted a finger 24 depresses a slidably mounted pawl arm 19 against the bias of a return-spring 20, the pawl slipping over a tooth on the ratchet-wheel 17 secured to the shaft 12, a detent lever 22 preventing movement of the wheel. On de-energization of the coil 7 the spring 20 lifts the arm 19 to rotate the shaft one step. The coil may be energized selfinterrupting fashion through a pair of contact blades 31, 32, a post 38 on the armature opening the blade 31. The blades are carried, respectively, by brackets 33, 34 which are pivotally mounted and engaged by the ends of rods 35, 36 threaded in a fixed bracket 37 whereby rotation of the rods adjusts the contacts 31, 32 (Fig. 4, not shown).
