Title: Process of making ceramic shells
IPC: B28B1/24
Filed: 1959-01-29
Abstract: 847,449. Moulding ceramic shells. NORTON CO. Jan. 29, 1959 [Jan. 30, 1958]; No. 3177/59. Class 87(2). A ceramic product of wall thickness less than 1/10 of the maximum linear surface dimension is made by heat-spraying a fusible ceramic material on to a rigid former, removing the former by eliminating at least that part of it adjacent the ceramic material, and then firing the formed ceramic material under conditions of time and temperature as measured by a pyrometric cone in the range from cone 12 to cone 42. The process is particularly useful for the manufacture of radomes, also nose cones for missiles and rockets. Examples of suitable ceramic materials are a rather pure form of alumina containing at least 95% by weight Al 2 O 3 , and a stabilised zirconia product consisting of zirconia plus hafnia plus lime to a total of at least 95% by weight. The former 11 on which the ceramic material 30 is heat-sprayed by spray gun 21, Fig. 3, is rotated on a support 14 driven by a motor 18 through a reduction gearing 17. The former may be made of carbon which can be burned out, it may have a surface of salt which can be dissolved, it may be a thin spun metal shell removable by means of acids or electrolysis, or it may be of aluminium and removable by differential contraction. At this stage in the process the shell, assuming alumina to have been used, is composed of γ-type alumina of density 3À62. Its characteristics are radically changed by high-temperature firing, e.g. to cone 35, the alumina changing into α-type of density 3À98, and the product becoming substantially non-porous and impermeable. In the embodiment shown in Fig. 6, the base 50 on table 51 supports a ring 52 which is rotated by the belt 53 driven by a mechanism such as shown in Fig. 3. An ogive former 55 of aluminium is provided and this is heated by a bunsen burner 56 while a salt solution is sprayed over it. The salt-coated ogive is then transferred to the plate 72 rotated by belt 73 and through which pass the coaxial pipes 76, 77. The former 55 is filled with water passed through pipe 77, the air escaping between the pipes 76, 77 and the water through a hole 81 of smaller diameter than the pipe 77, and heat-sprayed with ceramic material. The coated former is then placed in running water to dissolve the salt and the shell, separated from the former, fired as described above. Specification 745,257 is referred to.

Title: Improvements in Fluid-pressure Forging Presses.
Inventor: FIELDING JOHN
IPC: B21J9/12
Filed: 1917-03-06
Abstract: 113,826. Fielding, J. March 6,1917. Steam &c. presses.-In the forging- press shown in Fig. 1, the cross-head b is lifted by cylinders a and depressed either by the cylinders a or by a cylinder c actuating a liquidpressure cylinder r through a liquid column connected to a lower-pressure reservoir q. The steam and exhaust of the cylinders a, c are controlled by pairs of vertically-acting valves which are similarly operated by horizontal bars having inclined surfaces. A valve 12 is arranged in the pipe leading to the low-pressure reservoir and is actuated so as to permit ordinary forging, planishing, or piercing operations. Steam pressure is supplied constantly to the bottom of cylinders a through pipes o, p. During ordinary forging, the cross-head b is brought down to the work by the cylinders a, and the final pressure supplied by the cylinder c on the closure of the valve 12. During planishing, the upper ends of the cylinders a are put to exhaust, the valve 12 is closed, and the cross-head b is reciprocated by the cylinders a, c. When piercing operations are necessary, as in punching a deep hole or piercing an ingot, the upper ends of the cylinders a are supplied with steam and the press tool is forced downwards by each successive stroke of the piston in cylinder c, the valve 12 being suitably actuated through a fluid relay. The steam and exhaust valve spindles f, g of the cylinders a are connected by rods i carrying rollers j to a link l connected to a hand-lever k on the shaft k'. The rollers j, on moving the lever k, engage the inclines h<1> on the bar h and actuate the valves. The valves of the cylinders c are similarly actuated. The rod h of the clyinders a is connected to a hand-lever 5 and may be fixed in one of three positions corresponding to planishing, ordinary forging, and piercing operations. When piercing operations are unnecessary, the lever 5 is movable only to the left. Alternative fluid-operated means for moving the rod h are described. The bar h of the driving-cylinder c is weight or spring-controlled and is actuated by the pistonrod t through a hunting-gear to open the exhaust valve and close the steam-valve after the desired movement of the rod t has been effected by the movement of the hand-lever. The rod t carries an arm v connected to an inclined vertical bar w which actuates a roller y on a lever z having a fulcrum on a hand-controlled disk 2 and connected to the bar h. The valve 12 is actuated by a piston in an auxiliary cylinder 13, the valve of which is actuated by a tappet-rod 18 having a slot engaging a pin connected to a lever 19 pivoted at 20 and which carries a pin 19<1> engaging a cam-track 21<2> on a member 21 secured to the shaft 5<1> of the lever 5.

Title: Rotary take-ups for sewing machines
IPC: D05B51/00
Filed: 1951-02-12
Abstract: 681,880. Sewing-machines. SINGER MANUFACTURING CO. Feb. 12, 1951 [Oct. 11, 1950], No. 3316/51. Class 112. A rotary needle-thread take-up and slack-controller comprises a single element rotating uniformly about the axis of the needle-bar shaft, once for each needle reciprocation, and having parts in its plane presenting thread-controlling edges on opposite sides of its centre of rotation and parts on the same side of the centre bent out of its plane. The device described gives a quick, smooth, and early stitch-setting action, not sensitive to thread position, and a quick thread release. In the form shown the rotary member is of sheet metal and comprises a body 49, Fig. 11, arms 60, 61 with a bridge-piece 65 in a plane perpendicular to the plane of the arms and thread-controlling fingers 73 on the body and 66, 67 on the bridge-piece; a tail 75 on the body is bent backwards, and the parts of the arms 60, 61 adjacent to the bridge-piece 65 are also offset backwards. The body 49 is fixed, with a spacer 57, Fig. 4, interposed, to a disc 51 which is secured, so as to be angularly adjustable about the axis of the needle-bar shaft 35, to a disc 55 on an extension of the needledriving crank-pin 33, so that the take-up member rotates with the shaft 35; the disc 51 has a recess to receive the tail 75 of the take-up member. A fixed ring 56 surrounds the disc 51 to confine the thread laterally, and a guard 76 (omitted from Fig. 11), with a cover 78 which can be swung aside on a screw to give access to the take-up, is carried by a bracket 77 fixed to the machine head. The thread passes to the take-up through a guide 79, tension device 80, auxiliary take-up 81 and guide 83, and from it through guides 84, 85 to the needle. In the position shown, at maximum take-up, the thread can lie anywhere on the arm 60 without affecting the action; as the take-up rotates clockwise the thread being drawn down by the needle is prevented from flying off by the finger 73, and the limb extending to the needle is lifted on to the front of the take-up member by the tail 75 so that it is eventually controlled by the arm 61, being then kept from whipping, when freed from the finger 73, by the finger 66. A knife 86, with undercut edge, projects from the ring 56 into the plane of the outer ends of the arms 60, 61, about which a broken thread would become wound, to cut such thread; in normal operation the thread passes along the arm 60 below the knife. In a modification, Fig. 22 (not shown), the fingers 66, 67 are joined by an arcuate part extending round the opposite edge of the body 49 to act as a balance weight, the take-up parts still being accessible through the ring thus formed. In a leather-sewing machine the thread may be measured in accordance with the work thickness by placing the devices 80, 81, 82 higher on the head and mounting the guide 83 on the presser-bar opposite the guide 82.
