Title: Improvements in or relating to lubricating devices
IPC: F16H57/05
Filed: 1959-03-05
Abstract: 919,107. Lubricating. SCHMEMANN, A., [trading as DE LIMON FLUHME & CO.]. March 5, 1959 [March 20, 1958], No. 7631/59. Class 12 (3). In a lubricating device for link pins 2 or the like, comprising a lubricator body 4 housing a lubricating piston 7 terminating in a nozzle 8 which is adapted to be forced into contact with a pin 2 by lubricant under pressure entering an inlet 42, a control piston 11, located within the lubricating piston 7, blocks the passage of lubricant through a duct 25 to the nozzle 8 until the nozzle 8 has been moved into its operative position of engagement with the pin 2. The control piston 11 is engaged by a spring 12 which is stronger than a spring 10 which resists movement of the piston 7, and a central bore 27 in the control piston 11 communicates with a radial bore 26. The end of the piston 11 is acted upon by lubricant under pressure which, after causing movement of the piston 7, moves the piston 11 axially to bring bores 25, 26 into register and hence allows the flow of lubricant to the nozzle 8. In a modification, shown in Figs. 9 and 10, a lubricating head comprises a lubricating piston 7 in which are slidably disposed a control piston 11 and a supply piston 31. In the inoperative condition, the pistons are spring- pressed into the positions shown in Fig. 9. When lubricant under pressure is supplied through an inlet 42 it advances the lubricating piston 7, against the action of a spring 10, into engagement with a lubricating nipple 2. Some lubricant enters an aperture 33 in the piston 7, a recess 34 and aperture 35 in the supply piston 31 and forces the control piston 11 axially along the bore of the supply piston 31. Near the end of its stroke, piston 11 uncovers a port 36 which allows lubricant to pass through a groove 37 to the space behind the supply piston 31, thereby advancing the latter and causing lubricant from the space 46 to be ejected into the nipple 2. At the end of the stroke of the supply piston 31, it abuts a shoulder 40 in the lubricating piston 7, and a bolt portion 41, attached to the piston 11 closes the outlet 45 to the nipple 2, as shown in Fig. 10. On removal of the lubricant supply pressure, the springs 10, 12 return the pistons to their original positions shown in Fig. 9, some lubricant being trapped in the space 46 in readiness for the next ejection. The quantity of lubricant supplied may be varied by adjustment of a screw 38;

Abstract: 914,102. Centrifugal pumps. VOLLAND, G., and SCHULZ, W. March 4, 1960 [April 2, 1959], No. 7791/60. Class 110 (1). In a single-vane rotary pump the inlet edge of the single vane is situated on or near the axis of the rotor, the inlet aperture of which is eccentric to the rotor axis, and the vane embraces the inlet aperture. The pump comprises a rotor 5 driven by a coaxial shaft 6 and housed in a spiral casing 2 having an inlet 4 coaxial with the rotor and an outlet 3. The rotor 5 comprises a single vane 14 having inlet and outlet edges 15, 16, respectively. The rotor inlet aperture 13 which is elliptical in crosssection and eccentric to the rotor axis is embraced by the vane 14 such that the inlet edge 15 is approximately parallel with and on or near the rotor axis. The vane 14 extends the full 360 degrees and its distance from the rotor axis increases at a constant rate. The rotor has end walls 17, 18 connected by the vane 14. The minimum cross-section of the passage formed by the vane is a square having sides approximately equal in length to the minor axis b of the inlet aperture 13. This arrangement ensures that the inlet edge 15 of the vane 14 has a negligible peripheral speed which prevents the build-up of long fibrous particles along the inlet edge of the vane. A further advantage is to be gained by forming the inlet aperture with a conical surface 19 having an apex angle W which accelerates the flow into the inlet aperture 13 imparting a washing action to the inlet edge 15 of the vane 14.

Title: Improvements in and relating to valves for isolating high vacuum chambers
IPC: H01J41/12
Filed: 1962-02-28
Abstract: 954,954. Valves. Y. ARATA, and M. YAMAGOE. Feb. 28, 1962 [April 5, 1961], No. 7861/62. Heading F2V. A valve for isolating high vacuum enclosures embodies a cylindrical, moving closure member 14 with a sharp-annular seating surface and a transverse wall 16 housing an electric heater 17; the seat is provided by an annular trough 18 filled with indium metal. The member 14, which is sealed with respect to the valve casing 1 by an elastic bellows 15, has a hollow actuating rod 12. After a vacuum has been established in an enclosure by a rotary vacuum pump upstream of the valve the heater 17 is energized and the rod 12 operated to press the member 14 on to the indium 19; upon the latter melting the sharp seating surface dips into the indium, whereupon the heater 17 is de-energized and cooling water is admitted to the member 4 via a cook 25, a chamber 20 and the rod 12. The indium solidifies to effect a seal and separate one pump from the other; a super high-vacuum ionpump, downstream of the valve, is then operated to reach the desired vacuum level in the enclosure. To open the valve, the cooling water is withdrawn from the closure member 14 by opening another valve 27 and the heater 17 is switched on to again melt the indium, the closure member 14 being retracted by the resilience of the bellows 15. The indium metal may be replaced by a liquid metal, e.g. mercury, which is solidified by cooling, the valve being kept at a low temperature to effect a seal.
