The pump body 3a and stationary ring 6c may be of cast iron. In Fig. 2, extensions of the contact surfaces between cylinder support rings 6a, 6b and stationary ring 6c intersect at the neutral point Q. Rings 6a, 6b may be of tungsten or molybdenum. Resilient seals 17, 18, 19 prevent access of molten metal from reservoir 1a to the contact surfaces. Molten metal enters the cylinder during pumping via piston grooves 15, and is discharged via spout assembly 13a, 13b, the piston being reciprocated by piston and cylinder 10. In Fig. 5 (not shown), the cylinder has an integral flange (20) at one end with a contact surface engaging the stationary ring. In Fig. 7 (not shown), the cylinder has axially extending radial projections (31) engaging dove tail-shaped grooves (32) in a stationary ring, e.g. of ferrous metal. In Fig. 8 (not shown), the external wall of the cylinder (50) and the internal wall of the stationary ring or pump casing (53) have axial slots (51, 54) engaged by keys (52) of a material, e.g. tungsten or molybdenum, having substantially the same coefficient of thermal expansion as the cylinder.

Abstract: 957, 155. Photographic enlargers. MEOPTA, NARODNI PODNIK. Feb. 15, 1963, No. 6183/63. Heading G2A. In a photographic enlarger with automatic and manual focusing, the automatic focusing mechanism acts directly on a guide bar slidably mounted in the lamp house, the objective carrier sliding on the guide bar independently of the focusing mechanism. As shown, the support 9 carrying the objective 11 can be manually adjusted along the slide bar 7 by means of a knob 10, this adjustment being independent of the automatic focusing mechanism, which acts directly on the slide bar itself. A spring 8 maintains the slide bar in contact with one end of a lever 5, whose other end bears against a cam surface 61 screwed to a vertical standard 1. The whole enlarger head can slide along this standard, being secured in any position by a screw 3, the shape of the cam surface causing automatic adjustment of the focus via the lever 5.

Title: Improvements in or relating to composite metal castings
IPC: F16C33/14
Filed: 1941-05-16
Abstract: 549,483. Bearings. WHITEHEAD, E. J. May 16, 1941, No. 6365. [Class 12 (i)] [Also in Group XXII] To avoid porosity in casting composite bearings, e.g. as described in Specifications 371,559 and 549,090, [Group XXII], the bearing, after the lead bronze or the like has solidified, is heated to melt the lowmelting-point constituent and then cooled to allow this, from an unwanted part of the casting, or added low-melting-point metal, or both, to fill completely the interstices in the matrix of high-melting-point metal. The steel shell, between which and an asbestos-covered or other core the bronze is first-cast, may be cooled by water jets, the core be removed, the bore be machined, and a fresh core be fitted. The whole is then heated, with or without fluxes, low-melting-point metal is poured in, the temperature is raised to and kept at about 450‹C. and finally water jets are applied to the shell. In a modification the composite casting first formed is heated, with or without centrifugal action, to remove the lowmelting-point metal and then heated with another low-melting-point metal, such as tin or an alloy thereof. Centrifuging may be used to assist the low-melting-point metal to fill the cavities in the matrix completely and, if this is done, the added metal may be electro-deposited on the bearing before reheating. The process may be also applied to casting on the outer instead of the inner surface of the shell.

Abstract: 746,420. Forcing liquids by gaseous pressure. AKTIEBOLAGET SVENSKA KULLAGERFABRIKEN. March 4, 1954, No. 6397/54. Class 102(2). Apparatus for forcing liquids by gaseous pressure comprises a pair of chambers 5, 6 submerged in a tank 1 and mounted on a bearing on the support 3. Pressure air is supplied through the support 3 and passage 13 to a valve 14 that distributes it through passages 22, 23 alternately to the chambers 5, 6. Liquid enters the chambers through valves 7, 8 and is delivered past valves 9, 10 to a passage in the support 3. When one of the chambers is empty, the buoyancy, together with the reaction of the exhaust from passages 15, 16, causes the chambers to rotate on the pivot and move the valve 14 by engagement with the fixed abutments 18, 20. The land 40 of the valve 14 is shorter than the opening of the pressure air supply passage 13 so that during the changeover of the valve, both chambers 5, 6 are momentarily connected to the passage 13 to maintain continuity of the discharge of liquid.

Abstract: 249,129. Grigsby, B. J., and Grunow, W. C., (Assignees of Johnson, 0.). March 10, 1925, [Convention date]. Sound-reproducing diaphragms. - The vibrating portion of a diaphragm for a sound - reproducing device is circumscribed by a stepped peripheral seat or flange in such a manner that the intermediate connecting portion between the vibrating portion and the peripheral flange is stretched to place the vibrating portion under tension. In forming the diaphragm 6, a blank is first cut from a stock strip by the die member 26, 27, Fig. 8. The member 26 comprises two stationary members 26, 26<b> and an annular member 26<a> capable of downward yielding movement under pressure. Initially the upper surface of the member 26<a> coincides with those of the members 26, 26<b> and downward movement of the member 27 immediately results in the formation of flanges 31, 32, which are firmly gripped by the die members 26<a>, 28<a> upon being formed. After the flanges 31, 32 are formed and gripped, the flat portion of the blank is stepped once more by a further downward movement of the member 27 which depresses the member 26<a>, resulting in the formation of flanges 34, 35. A stretching of the material is effected during this last operation beginning at the shoulder 36 or extending towards the centre. The final step consists in trimming off the flange 31 as shown in Fig. 9. To prevent a substantial bowing of the flat portion of the diaphragm, the punch of the member 27 is preferably arranged to give the diaphragm a final blow after the flange-forming operations are accomplished. In a modified construction of diaphragm, the flange 32 is omitted.
