Title: Improvements in or relating to copying machine tools
IPC: B23Q35/20
Filed: 1957-09-09
Abstract: 817,926. Copy-milling. DECKEL, H., and DECKEL, F. W. Sept. 9, 1957 [Sept. 28, 1956 ; Nov. 16, 1956], No. 28359/57. Class 83 (3). A copying-machine-tool comprises a pantograph 10, 12, 14, 16 having a link 16 hinged at 18 to a fixed support 20, which may be angularly adjustable, and a second link 14 articulated thereto and carrying a tool or tracer-holder 30, a two-member articulated-linkage 32, 34 hinged at one end to a fixed point 36 and carrying a supplementary holder 38 at its other end, the anchored member 32 of the linkage being guided in parallelism with the anchored link 16 of the pantograph, and the other member 34 being guided in parallelism with the said second link 14. The link 34 is attached to the pantograph by way of links 40, 42 of the same length as the distance between the pivots 18, 36, which latter distance is set by adjustment of a bar 72. The links 40, 42 themselves are joined by a link 44 and supported by an adjustable extension arm 16a and an adjustable link 54. By adjusting the linkage to the position shown in broken lines in Fig. 1, so that the link 14 lies below the link 44, a tracer 80, Fig. 2, in the holder 38, will move in a 1: 1 ratio with a tool 78 in the holder 30. With the supplementary. linkage, the machine may copy with ratios from 1: 1 to 1.5: 1, and the range is extended from 1.5: 1 to 10: 1 with the pantograph itself. All the adjustments are made against calibrated scales, and those for the supplementary linkage, namely, scales 16b and 54a, may be calibrated in percentages of shrinkage allowance when working from a wooden model. The tracer is guided by a handle 86. The members 44, 16a, 54 may be omitted if a 1: 1 ratio only is required. In a modification, the arm 16a, Fig. 5, forms an extension of the link 32. In further modifications, tracers or tools can be fitted in any of the holders 24, 30, 38, and two workpieces can be reproduced to different scales simultaneously; a pivoted extended link may connect the links 40, 42, Fig. 1, and carry a further holder, or the end of the link and the holder 38 may be joined by another link carrying several tool-holders; and, finally, the machine of Fig. 5 may be modified in the same way as that of Fig. 1 to carry several tool-holders.

Abstract: 464,296. Pleating-machines. EZBELENT FILS. Oct. 16, 1935, No. 28649. Convention date, Sept. 20. [Class 141] A pleating-machine for obtaining flat and upright pleats, comprises two knives 11, 12, which produce the pleats by co-operating with two cylinders 25, 26, located between the knife carriers 5, 6, and on either side of the planes of the knives 11, 12. The knives may each have imparted thereto a horizontal and a vertical movement, the former being effected by means of two levers 1, 2, operated by cams 7, 8 on a main shaft 9 and pivotally connected at their other ends to the knife carriers 5, 6, by links 3, 4, and slide pieces 10 ; the vertical movement is effected by two cam-operated levers 13, 14, and links 40, 41 secured to the knife carriers control the pivotal movement of the knives. The upper cylinder 25 is mounted in a frame 30 which has a horizontal movement imparted thereto by a cam-operated lever 21, Fig. 2, having a forked end 24 which engages with a stud 33 mounted on the frame 30, vertical movement of the cylinder 25 in the frame 30 being effected by a lever 20, Fig. 2, pivoted to a cam-operated lever 19. Flat pleats may be formed by causing the knives 11, 12 to execute horizontal and vertical movements so that they cross upon one another, and by causing the upper cylinder 25 to move either horizontally or vertically. Upright pleats may be formed by causing the knives to execute only horizontal movements, the pleats being formed by gathering due to the descent of the upper cylinder 25 upon the material to be treated. The cylinder 25 is provided with a sector 39 which is removed when it is desired to form upright pleats. The knife carriers 5, 6 may be connected together so as to move the knives in a direction parallel to the axes of the cylinders 25, 26.

Title: Improvements in or relating to air separators for powders and granular materials
Inventor: RODGERS JEFFREY CHRISTIAN
IPC: B07B4/02
Filed: 1968-05-24
Abstract: 1,200,996. Centrifugal separators; pneumatic classification. BRITISH "REMA" MFG. CO. Ltd. 19 May, 1969 [24 May, 1968], No. 24817/ 68. Headings B2H and B2P. A pneumatic separator for classifying particulate material comprises a pipe 7 for feeding the material to be classified to the interior of an angularly vaned rotor 12, a spinner disc 13 for flinging the material to the rotor vanes, an inner cyclone casing B with its top 4 surrounding the rotor 12, a fan 14 for producing a swirling stream of gas in the space between the casing B and the outside of the rotor 12, a passage leading from the interior of the rotor to the inlet of a circulating fan 11, an outer cyclone casing A with its top 1 surrounding the circulating fan 11, an axial pipe 16 connecting the lower part 3 of the outer casing A to the inlet of the swirling fan 14, an outlet 20 in the bottom of the inner casing B for removal of coarse particles, an outlet 19 in the bottom of the outer casing A for removal of fine particles, and a tube connected to the fan 11 and mounted in a bearing 8 and driven by a motor 10 so as to rotate the fans 11, 14, the rotor 12 and the spinner disc 13. In operation, the material is flung from between the disc 13 and an upper annular plate 15 into the swirling stream of air and is entrained thereby through the vanes of the rotor 12 in which the action of centrifugal force on the coarse particles is greater than that of the drag force of the inwardly moving gas stream so that these particles are flung outwardly in the gas stream and are separated therefrom in the inner cyclone casing, whereas the fine particles on which the action of the drag force is greater, are entrained with the gas stream into the fan 11 and flung thereby into the outer cyclone casing where they become separated from the gas stream which is recirculated via the pipe 16. A valve 17 in the pipe 16 controls the rate of circulation of the gas stream. A labyrinth seal is provided at 18. The rotor vanes are non-radial. The outlets 19, 20 are closed by receptacles or air locks so that the entire gas content is retained within the separator. In a modification, Fig. 3, vents 23 controlled by an adjustable shutter 24 are provided in the wall of the inner cyclone casing B for tapping gas from the descending gas stream in the outer casing and directing it into the inner cyclone casing so that it flows upwardly through the space between a flared end portion 21 of the pipe 16 and a conical deflector 22 and thereby removes from the descending flow of coarse particles any agglomerated fine particles entrained therein and/or any ultra-fine particles which remain in suspension in the recirculated air and direct them towards the rotor 12. Auxiliary blades 25 are provided on the upper shroud of the fan 11 to produce suction conditions so as to prevent emission of dust to the atmosphere via the gap between the tube 9 and the cover plate 2 of the outer cyclone casing.
