Title: Two-roll machine for rolllng articles of disc form
IPC: B21H1/02
Filed: 1974-08-28
Abstract: 1440412 Rolling metal discs N I INST TEKHNOL TRAKTOR I SELSK-KHOZ MASHINOSTROENIA 28 Aug 1974 37544/74 Heading B3M A disc rolling machine comprises a frame 2, 3 supporting pivots 4, 5, 6, 7 and part circular guides 11, Figs. 1 and 2, on which move two sliders 8, 9, a rolling head 28 on each slider and a work roll 46 on each head, Fig. 4, a disc-supporting carriage 57 movable on the frame, and drives for the various movements. As shown, the sliders are rotatable about their shafts by gears 21 engaging racks 23 on the sliders and driven by a common motor 12. Each rolling head 28 is adjustable on its slider about pivot 29 by jack 31 and toggle linkage 33, 34 adjustable by nuts 38. The workpiece 60 is supported by arms 58 urged to the holding position by spring 59 but operable by levers 63 operable by jack 62. Each roll 46 is supported in its head 28 in a spindle 41 mounted by radial and thrust bearings 39, 40, 42. The roll is retained by head 44, cone 43, and puller 45 and nuts 50. Each roll is driven by its own electric motor 51 through gears 52, 53, 54, 55. In operation, at the beginning of a cycle, the sliders are located remote from the central axis O-O, and the rolls are moved away from the rolling zone B by rotation of the heads on the sliders by retraction of jacks 31 and collapse of linkages 33, 34. The carriage 57 is withdrawn to a loading zone. Jack 62 is extended to permit loading of a workpiece on to the arms 58, and retracted to secure the workpiece. The carriage is advanced to position the workpiece in the rolling zone. The rolls are driven, and advanced into the rolling zone by extension of jacks 31 to straighten the toggles. The sliders are then rotated towards the axis O-O, while the carriage is automatically moved along axis O-O to position the workpiece suitably as rolling proceeds. When rolling is terminated by the sliders operating switches 24, 25, the starting position is resumed and the workpiece falls to a discharge device.

Title: Improvements in hermetically sealed cased electrical condensers
Inventor: COOK RONALD JOHN
IPC: H01G2/12
Filed: 1954-12-30
Abstract: 786,965. Capacitors; couplings. LONDON ELECTRICAL MANUFACTURING CO., Ltd. Dec. 30, 1954, No. 37669/54. Classes 37 and 38 (1). In a capacitor comprising a plurality of parallel electrodes mounted between insulating plates 1, 2 and embedded in a body of a casting resin 5, the terminal wires 4 are clamped to the capacitor electrodes by rivets passing through the plates 1, 2 while a rubber or neoprene packing is interposed about each rivet between the respective terminal wire and electrode to prevent the entry of moisture into the capacitor structure along the terminal wires. In the construction shown, the terminal wire 4 is integral with the head of the rivet 3 and a rubber or neoprene washer 8 is interposed between the head of the rivet and the insulating plate 1. The rivet is shown as being of the eyelet type and is closed by solder 9 which also provides electrical connection between the rivet 3 and the metal contact strip 6 making contact with one electrode of the capacitor. The casting resin in which the capacitor is embedded is chosen so as to adhere to the material of the packing member 8, so that the member 8 provides an effective seal against the entry of moisture along the terminal wire 4 into the capacitor structure. In modified constructions, Figs. 3 and 4 (not shown), the terminal wire 4 is not integral with the head of the rivet 3 but is formed with a ring or eyelet encircling the rivet and clamped between the head of the rivet and the sealing washer 8. It is further stated that the insulating plates may be coated with a layer of neoprene or made entirely of neoprene, in which case the individual washers 8 may be dispensed with.

A gauge glass 10 for a tank 12, in which a liquid is maintained under pressure by a gas supplied through a pipe 22, is enclosed together with its connecting fittings 16 in a housing 14 having side windows 18, the housing being supplied through a pipe 24 with gas at substantially the same pressure as that in the tank so that the gauge glass 10 is relieved of any substantial pressure differential. The arrangement is especially applicable when an escape of liquid would be dangerous. For example, the tank 12 may contain liquid sodium or potassium used as a heat exchange medium in a system to which the tank is connected by a pipe 20, in which case an inert gas such as argon is supplied to the tank and housing. To enable the presence of liquid in the housing to be detected quickly a leakage detector is connected to the lower part of the housing by means of a pipe 26.

In a reciprocable spool valve controlling flow through a chamber 18 between an inlet 11 and outlet 12, the frictional force opposing movement of the spool is reduced by the provision, on at least one landed bearing part such as 15 of the spool of a passage or passages 24, 25, 26 extending through the interior of the spool, the or each passage opening at one end adjacent the inner edge 28 of the land and at the opposite end adjacent the outer edge 27 of the land on the opposite side circumferentially of the spool. Thus the leakage outwardly along the land from chamber 18 tends to flow through the passage or passages and if the clearance at one side between the land and the valve body 10 is reduced the pressure on a zone of the land at the corresponding end of a passage tends to increase whilst the pressure on a similar zone at the opposite end of the passage tends to increase, whereby the clearances at opposite sides circumferentially of the land tend to equalize and dry rubbing contact of the parts is avoided. As shown, a symmetrical arrangement of the three passages 24, 25, 26 is provided. Each passage, at the end adjacent the outer edge 27 of the land, opens into an open cavity in the spool provided by respective recesses 21, 22, 23. Similar provision of passages and recesses may be made, as shown, on a second land 16 of the spool, this being a controlling land for the outlet port 12. In this case the chamber pressure is communicated through a passage 35 to an annular recess 34 which remains clear of the port 12 and from which the leakage outwardly along the land effectively commences. The spool may be lapped into the body with a normal clearance of 0.0001 to 0.00005 of an inch and the controlled fluid, which also sustains the bearing, may be air.

However, when the fuel in a tank 10 reaches a level to seal vent 42 a vacuum is created above a diaphragm 36 causing the plunger 26 to become unlocked and thereby enabling spring 38 to lower the valve 22 and plunger 26 to close the valve and release latch 30. In addition the same result can be achieved when a predetermined pressure above atmospheric occurs in tank 10 which is sealed during filling as shown, the pressure being communicated through tapping 60 to the underside of a second diaphragm 46 which moves in the same direction as the diaphragm 36 to cause unlocking of the plunger 26. To avoid the pressure communicated through vent 42 to the space above diaphragm 36 from neutralizing the effect of the pressure acting on the underside of diaphragm 46, a recessed platform 52 is provided against which a substantial portion of the diaphragm 36 is forced by the pressure.
