Abstract: 314,150. Groves, W. W., (Cook Labora. tories, Inc.). April 10, 1928. Capsules.-Surgical syringe cartridges comprising glass tubes 7, Fig. 2, closed at one end by rubber plugs 8 employed in use as plungers, and at the other end by flanged plugs 9 having internal axial recesses, are filled by needles pressed through the plugs 9 and comprising inner and outer tubes 23, 29, Fig. 3, the tube 23 communicating with a bifurcated passage 33 in a detachable needle point 32 and the tube 29 having a lateral aperture 31. The upper ends of the tubes communicate respectively with nipple 24, Fig. 2, secured axially in a plug 21 and with an annular space 22 in the plug 21 surrounding the tube 23 and having a lateral aperture leading to a nipple 26. The nipples 24, 26 are connecting by rubber tubes 14, 28 with a supply of sterile medicament and a vacuum pump respectively. The plugs 21 may be inserted in the plugs 9 by hand or two or more may be held in a frame 15 for filling a corresponding number of tubes simultaneously. In the latter case the frame 15 is furnished with spring-pressed plates 38, Figs. 2 and 5, which bear upon the plugs 9 and prevent their withdrawal from the tubes 7 when the needles are removed. The tubes 7 are held during filling in vertical spring clamps 37 unon a rigid support 11, a rubber cushion 42 being interposed to obviate breakage and prevent the plugs 8 from being drawn into the tubes by suction. The frame 15 is carried on a pivoted arm 16 Fig. 5 which is depressed by a treadle 17 and returned by a spring 18. Screw-adjusting means 46 are provided to adjust the distance of penetration of the needles into the cartridges. The tubes 14 are furnished with filters 45 and pinch cocks 44 and extend to the bottom of the medicament vessels 12 which are open to the atmosphere through filters 13 preventing the ingress of bacteria. The needles 23 are inserted sufficiently far into the cartridges to permit the apertures 31 just to communicate with the interior thereof. Air is thus drawn off from the upper end of the tubes and the medicament delivered at a point lower down, the ports of the passages 33 being preferably inclined in a downward direction. Complete filling of the tubes is thereby effected and foaming of medicament involving loss through the apertures 31 is prevented. A vacuum trap may be provided in the suction tubes 28.

Title: Improvements relating to machines for automatically producing pressure-shaped articles, more especially tapered bore rivets
IPC: B21K1/58
Filed: 1940-06-24
Abstract: 543,512. Forging hollow rivets &c. AVIATION DEVELOPMENTS, Ltd., and MUMFORD, R. H. June 24, 1940, No. 10796. [Class 83 (iv)] In a machine 1 for shaping tapered bore rivets or other articles by pressure having a mould 9, Fig. 6, moved step-by-step relative to a shaping tool 25 first to receive a blank at A, then to shape the article at B and finally to eject it at C, the mould has a plunger 11 which serves, in the first position A of the mould, to locate the blank, in the second B, as an anvil and, in the third C, to eject the article. A number of moulds is carried by a drum 2 rotated, step-by-step, about a fixed cam 15 by a ratchet thereof engaged by a pawl 28 during the last part of the up stroke of a slide 22 to which it is pivoted and which carries the tool 25. Hollow blanks fed by a tube and co-axial wire through a slot 32 of a plate 31 are received one in the recess 10 of each mould as it reaches the position A. At the next movement of the drum 2 a mould containing a blank is brought to the position B and the descending tool 25, guided by a skirt 23 engaging a recess 8 in the drum, shapes the blank. In positions A and B the plunger 11, which may have a frusto-conical recess in its active face, is supported by its projection 13 engaging surfaces 19, 20 of the cam, to form a bottom to the recess 10. At the next movement of the drum the mould, containing the shaped article, is brought to the position C, during which movement the projection 13 passes to a high surface of the cam thus lifting the plunger 11, against the action of a spring 14, to eject the article. In a modification a second shaping tool may operate at position E, blanks being fed at D and ejected at F. In further modifications there is more than one mould 9 at each angular face and a corresponding increase in the number of tools 25. The moulds, plungers, and tools may be inter-changeable with others of a different size and shape. The machine 1 may be used with any suitable press and may e.g. be bolted at 36, Fig. 1, to the inclined bed 33 of an eccentric press, driven through variable speed belt gear 46 from an electric motor 45. The press slide 43 may be connected by a yoke 44 to the ends of a rod 26 secured to the slide 22.

The chamber 2, Fig. 5, is divided into compartments 7, 8 in which stockings on forms 65 are treated with air from a central blower which passes over heating coils 29 and round baffles 32, 33, and is returned through openings 10, 11, the walls and doors of the chamber being lined with thermal insulating material 14.  The chamber 2, Fig. 3, is mounted over guideways 40, 41, each comprising spaced rails 42 which carry supports 50, 51, 52 and 53, in the form of lazy tongs, the forms 65 being fastened by wedge levers 67 to alternate links of the supports, Fig. 18.  A motor 103 drives through gears a rack-and-pinion 88, 89, which causes a carriage, Fig. 7 (not shown), to displace the supports 50, 51 to the right.  The projection 60, Fig. 6, causes door 17 to open and due to the linkages 123, 125, 127, doors 15, 16 and 18 open. Since the lazy tongs are attached to the carriage at the extreme left and right ends, respectively, the support 50 collapses and 51 opens. As the support 50 reaches the position previously held by support 51, a projection 61 engages the lug 136, causing the doors to shut.  The supports 52, 53 travel to the left with a similar door-opening and closing mechanism, operators at A and B are then able to remove the treated textile and replace with untreated material before the motor 103 is reversed and the supports driven back to the position shown. Limit switches are arranged so that when the carriage reaches an extreme position, electrical connections are changed and the next operation of a start-button causes the carriage to move in the opposite direction.  Specification 568,946 is referred to.

Abstract: 1,169,815. Disc brakes. KELSEY-HAYES CO. 10 March, 1967 [11 March, 1966], No. 11430/67. Heading F2E. A disc brake comprises a movable caliper 49, Fig. 2, having spaced legs 51, 53 lying on opposite sides of a disc 19, a blind cylinder bore 77 in one leg, a machining access opening 87 in the other leg and a pair of brake pads (93, 95), Fig. 4 (not shown), on either side of the opening. The caliper is carried by a torque member 35 secured to a steering knuckle assembly (not shown) supported by spindle 15 through a conventional king-pin arrangement. In a rear wheel version the member 35 is directly secured to flange 41 of a stationary wheel spindle 15. The caliper 49 is slidable between inwardly facing flanges (55, 57), Fig. 3 (not shown) of outwardly extending torque arms of the member 35. A spring strap 59 is secured to the caliper 49 so that pads 93, 95 are drawn lightly into engagement with disc surface 22 when the brake is inoperative. Webs 31 move cooling air outwardly through openings 33 when the disc is turning. When pressure fluid is admitted from conduit 111 through port 109 into cylinder 77 the piston 79 is forced to the right (in Fig. 2) to engage the brake pad 85 with disc surface 27. This movement also causes the pads 93, 95 to be engaged with disc surface 99 and the strap 59 flexes slightly to permit the direction of the application to remain normal to the disc surfaces. When fluid pressure is released the spring pressure of an annular seal 113, which is distorted during the rightwards movement of piston 79, causes the latter to move towards the blind end of bore 77.
