Title: Casting or moulding of material by centrifugal force
IPC: B28B21/94
Filed: 1961-09-12
Abstract: The internal surface of a hollow article such as a pipe is lined with settable material by a process which comprises providing at least one perforation through the wall of the article leading to the surface to be lined, placing the perforation in communication via a feed passage with a feed opening for settable fluid material, rotating the article about an axis, the surface of the settable fluid material in the feed opening being closer to the axis than the surface of the article to be lined, whereby the settable fluid lining material flows outwardly from the feed opening away from the axis and then along the feed passage via the perforation into the hollow article and along its inner surface. The article may be a pipe of cementitious material, and the settable lining material may be a synthetic plastic.  As shown (Fig. 1) a pipe 10 has an end 12 of lesser diameter than the main body part and in the reduced diameter end there are formed circumferentially spaced holes 16.  A mould 18 fits around the main body part and is adapted to seat against the taper shoulder 20.  The end wall 22 of the mould defines a cavity 24 with the end 12 of the pipe, and is formed with an opening 26 of diameter slightly smaller than the internal diameter of the pipe.  If desired, several axially spaced holes and grooves interconnecting them may be formed in the pipe 10. <PICT:0932508/III/1> In operation, the pipe and mould are spun about the pipe axis and settable fluid material introduced through opening 26.  This flows under centrifugal force through opening 28, along cavity 24, inwardly radially through holes 16 and into the bore of the pipe.

Patent GB-1112583-A (GB)
Title: Process of producing high-strength ore pellets
Inventor: SCHENCK HERMANN
IPC: C22B1/14
Filed: 1965-07-30
Abstract: High strength ore pellets are produced by a process in which the ore to be pelletized is mixed with 10 to 50% (by weight based on the dry weight of the resulting mixture) of prefired ore.  The proportion of prefired ore in the pellets may be higher in the outer zone than in the interior of the pellets and the pellets may consist of a core free of prefired material and a plurality of shells containing increasing proportions of prefired material. The prefired material may be produced by subjecting sintered pellets to a stress which is sufficiently high to produce the required amount of prefired material in the form of abraded material and broken pellets, or it may be produced in a down-draught sintering plant.  Alternatively, fine grained ore may be heated to a temperature in or slightly below its sintering temperature range whilst maintaining its particle size and added to the crude material to be pelletized or the material which is admixed with the ore may be prefired under reducing conditions to give a prereduced prefired product. Examples relate to the products of pelletized iron ore.

Title: Improvements in the connection of material by stitching
IPC: D05B1/24
Filed: 1926-12-29
Abstract: 275,149. Union Special-Maschinenfabrik Ges. July 29, 1926, [Convention date]. Stitches and seams; multiple-needle sewing-machines; blind stitching machines; trimming.-The two flat adjacent edges of material to be connected by a blind-stitch seam 4, Fig. 1, are first raised and then trimmed to the same depth before the bending seam is made., and the edges of the material are subsequently covered. The material is fed to the trimming mechanism with the edges in the position of an inverted V and may be bent, alter trimming and stitching, for the purpose of covering, in such a way chat a third horizontal face is formed between the two inclined faces. The binding seam, Fig. 10, is formed of two needle threads which are passed through the edges of the material from both sides forming two oppositely arranged single chain stitches which mutually lock one another. The thread lays, which are the same on both sides, consist of alternating loop lays of a length of one stitch and binding lays two stitches in length. The stitch passage for the covering seam lies above or below the stitch passages for the connecting seam and is adjusted relatively thereto. The seam is made in a machine, Fig. 15, having three needles oscillating in an arcuate path, two, 8, 9, for stitching together the edges and one 24 for covering purposes. The work is fed along a cylindrical work support 39 by dogs. The needles 8, 9 co-operate with threadless loopers opposite the needles, which take up the thread loops and retain them spaced open for the passage of the next needle, and a thread carrying looper co-operates with the covering needle 24 to form the covering seam. A stitch-plate 7 in the form of an inverted V and a similar shaped presser foot 1 having two inverted V-shaped side walls separated by a slot 3, Fig. 4, co-operate to raise the edges of the material for trimming which is done by a stationary blade 5, Fig. 2, and a blade 6 moving counter thereto. The needles 8, 9 move in circular paths behind the blades 5, 6 and on opposite sides of the work to stitch the two edges 4 of the material together, a slot 10 being provided in the presser foot 1 for the passage of the needles 8, 9. A channel in the presser foot receives the raised seam rib 4 and forces it into a feed guide 13 in the stitch plate by a downwardly directed member 12. The stitch plate 7 and a cloth support 16 are adjustable in height as shown in Fig. 4 to alter the height and depth of the stitch passage of the covering needle 24. A tongue 22, Fig. 2, also adjustable in height to correspond with the adjustment of the stitch-plate is mounted on the covering side of the presser foot 1 so that the apparatus continues to chain-stitch without material.

Title: Improvements in or relating to presses operating entirely automatically
IPC: B30B9/06
Filed: 1936-11-30
Abstract: 491,581. Presses for separating liquids from solids. WIDMER, L. P. Nov. 30, 1936, No. 32854. Void. Convention date, Nov. 30, 1935. [Class 46] A filter press for fruit, oil, peat, &c. comprises a pressing piston and a counter pressure piston which are coupled together so that, after the pressing operation, the counter pressure piston is pushed out of the pressing chamber together with the press cake. Fruit &c. 2 is disintegrated by a toothed drum 3 and fed into the space 4. The pressing piston 6 has a piston rod 7 actuated by a hydraulic piston 9 and a support 10 which operates a valve 16 through a rack 13. The valve 16 is connected to a fluid pump 26 so that pressure is supplied through pipe 21 or 22 to move the piston 9 backwards or forwards. The pump 26 may comprise two long stroke low pressure cylinders and two short stroke high pressure cylinders, valves being provided for automatically cutting out the low pressure cylinders when the back pressure increases to a predetermined amount. The cylinder 5 into which the fruit mass is fed has slots 5c and a discharge pipe 5e through which the expressed liquid passes. The counter pressure piston 27 is connected to a piston 30 working in a cylinder 29, piston 30 having a ball valve 30a which opens at a predetermined pressure and allows the piston 30 to move back. The two ends of the cylinder 29 are also connected by pipes 31, 31a controlled by a valve 32 which is actuated by a support 34 on the piston rod 28. The piston rod 7 carries a yoke 35 which is resiliently connected to a similar yoke 40 on the rod 28 so that on the return stroke the piston 6 draws back the piston 27 also. In operation, fluid pressure is admitted to the cylinder 8 to advance the piston 6 and compress the fruit mass against the piston 27. At a predetermined pressure the valve 30a opens and the piston 27 yields slowly until the support 34 opens the valve 32 and allows the piston 27 to move out of the cylinder 5 quickly together with the press cake. The cake is then ejected by a fluid operated stripper 42. The support 10 then operates the valve 16 to reverse the motion of the piston 6 which also draws back the piston 27 into the cylinder 5.
