IPC: B02C15/12
Filed: 1919-06-21
Abstract: 129,631. Odam, E. July 10. 1918, [Convention date]. Ball-and-ring mills.-In a process for pulverizing granulated or scrap metal in the cold by means of apparatus comprising balls rolling in races, the scrap &c. enters the apparatus axially and leaves peripherally, and is caused by centrifugal force to pass repeatedly between the balls and races, or in a modification, to pass through a series of apparatus. The process may be carried out in the mill shown in Fig. 3, in which the ring of balls f is arranged in races in a stationary plate v and a rotating plate a which is formed with a central sleeve b, arranged above a conical boss d on the plate v. The plate a is secured by a bar r to a driving-shaft p, engaged by a pressure-adjusting plate o which can slide on bolts r., provided with springs s and nuts t. The sleeve b is arranged within a casing h formed with a feedopening i and a discharge opening j. In operation, the casing and the sleeve b are filled with scrap &c., the openings i, j are closed, and the mill is started, the rotation of the plate a causing the material to pass slowly between the balls and to circulate in the paths indicated by the arrows f<2>, f<3>, f<4>. In the mill shown in Fig. 4, the material passes through two or more ball-and-ring apparatus u<1>, u<2> which are arranged at the bottom of conical hoppers h<1>, h<2> respectively and are driven by a common shaft p. The shaft is feathered to the rotatable plate x of the device u<1> and to a bar r<1> secured to the rotatable plate y of the device u<2>, a spring s<1> being arranged between the plate x and the bar r<1>.

Title: Improvements in seams for sewed articles
IPC: D05B93/00
Filed: 1922-06-06
Abstract: 190,978. Imrie, H., (Arbetter Felling Machine Co.). June 6, 1922. Stitches and seams. - Two layers of material are connected together by a blind-stitched seam in which a thread is disposed in two series of parallel loops each at an angle to the edge of the superposed layer. One series enters and emerges from the upper surface of the main layer and extends beneath the surface of the upper layer, and the two series are concatenated by an additional thread. In the arrangement of loops shown in Fig. 1, which is intended for production by a. machine having a curved laterallyjogged needle moving in its penetrative stroke inwards of the upper layer, the needle alternately enters the lower layer 1 at 6 and emerges at 7 producing a loop 8, and then enters the lower surface of the layer 2 at 9 and emerges at 10 producing a loop 11, the loops 8 and 11 being concatenated by a thread 5. In Fig. 2 a needle is shown moving outward from the work, and while entering and leaving the layer 1 as before at 13, 14, it enters and leaves the lower side only or the lower side and edge of the layer 2 as at 17, 18. The relative tensions of the concatenating and main threads may be adjusted so as to roll over the edge of the upper layer and to conceal the line of stitching.

IPC: B21C23/28
Filed: 1950-06-23
Abstract: 699,082. Extruding. LOEWY ENGINEERING CO., Ltd May 30, 1951 [June 23, 1950; June 23, 1950; July 26, 1950; July 26, 1950], Nos. 15699/50, 15700/50, 18678/50 and 18679/50. Class 83 (iv). A method for extruding light metal cable sheathings in which the cable is fed diametrially across the bore of the billet container of an extrusion press comprises feeding in succession a number of solid billets axially into the container and extruding the billets directly into contact with the cable, each billet welding itself to the non-extruded portion of the previous billet left inside the container. The press comprises a container 10 having a chamber 14 and a ram 12 for extruding a billet B. The end of the container remote from the ram is closed by a removable plug 18 locked in position by a wedge 38. The container has two oppositely arranged crossbores 20 leading into an extrusion chamber 16 and accommodating a hollow mandrel 22 and a die 24, through both of which passes a cable to be sheathed. Both mandrel and die may be adjusted axially by screws 30 in order to vary their protrusion into the chamber 16. Heating means may be provided inside or around the container 10 and also inside the plug 18 in a bore 34. In operation the cable is fed through the mandrel and die and a number of billets B are introduced in succession into the chamber 14 and extruded through the die and around the cable. Each billet is only partially extruded so that the following billet can weld itself to the previous one. At the end of an extruding operation the discard D is removed by the ram 12, having first withdrawn the mandrel and die and the wedge 38 from the sealing plug 18, by inserting a hollow distance piece 46 and a solid disc 48 between the ram 12 and the discard D. As the plug 18 generally adheres to the discard the plug, discard and disc 48 are removed by means of a handle 42 on the plug. In a modification, the container 10 is open at each end for introducing solid billets B1 and B2 (Fig. 8). The discard is removed in this case by placing a spacer member 50 between the ram 131 and the container 10 and inserting a disc 48 and two hollow pieces 46 and 47 between the discard and the ram 132. To ensure that the mandrel and die are held firmly in position rearward extensions of greater diameter than the remainder of the mandrel and die provide two spaced bearing surfaces 202 and 201. Behind the mandrel and die in the crossbore are backing sleeves 70 carrying heads 72 which are attached to the container by studs 74 and nuts 76. Protrusion of mandrel and die into the chamber 16 is adjusted by means of distance rings 78. Cooling means (not shown) may be arranged within the rearward extensions of the mandrel and die.

Title: Time division mutliplex transmission systems
IPC: H04J3/06
Filed: 1973-04-04
Abstract: 1406163 Digital transmission; synchronizing T.D.M. SIEMENS AG 4 April 1973 [3 May 1972] 16002/73 Heading H4P Whenever a T.D.M. channel has no information to carry, it sends a self-identification code which the receiver uses to check or retrieve synchronization by resetting its own channel counter accordingly. At the receiver E m , Fig. 1, clock bits BT are counted at Z3 to produce one pulse K T  per channel (4 bits per channel), and the K T  bits are counted by a channel counter Z4 whose three-line output identifies the channel number. Data received from link JK by a register ER is gated G11- G14 into a word input register WRe and thence by normally conducting gates G15-G17 into the appropriate word cell of a store S2, the word cells K1-K8 being selected by a decoder D4 responsive to the channel counter Z4. When a non-information-carrying channel occurs, this is identified by a "0" in the fourth bit position, which when it reaches register WRe blocks G15-G17 and enables G18-G20. Thus the remaining three bits are passed by normally conducting gates G21-G23 to a comparator V which signals at F any non-identity with the locally calculated channel number from Z4. At this point V is disabled, a synchronizing unit Sy is primed and the clock train BT is displaced at RE. When the next channel identifying word is received, the fourth stage of WRe is "0" and enables the primed unit Sy to block G21-G23, and to render G2-G26 conductive so that this channel number is fed direct to Z4 to reset it. Normal operation is then resumed until the next channel identifying word is received; if the previous resetting sequence was unsuccessful, or if synchronization has been otherwise lost since the resetting, the procedure is repeated as many times as is necessary to resume correct synchronization. The transmitter SE operates in generally similar but reversed order to the receiver, but without the channel word-checking arrangement.

Abstract: 1386808 Heat-treating high temperature alloys GENERAL ELECTRIC CO 7 April 1972 [22 July 1971] 16084/72 Headings C7A and C7N A solid state process for producing a columnar grain structure consists of treating the alloy to develop a dislocation density such that when the alloy is heated to 50% to 100% of the incipient melting temperature in degrees Rankine it will develop a grain size the largest dimension of which is at least 200 microns, and then progressively heating the alloy into that range by passing through it a temperature gradient of at least 500F/inch, the high temperature end of the gradient leading. The process is applied particularly to alloys based on Fe, Ni, Co, Ti, Cr, W or Mo, when the thermal gradient may be 500-5000F/inch advancing at 0.5-144 inches per hour. The alloy may be strengthened by oxide dispersion, precipitated γ1, or rare earth metal addition. In particular examples an alloy of 80% Ni and 20% Cr dispersion strengthened with 2 volume % of thoria was extruded at 1800-1860F and was then heated progressively to 2400-2425F by passage of a temperature gradient of 1500-2000F/inch at a rate of 0.1 inch, 0.5 inch, 5 inch, 24 inch or 72 inch/hour. Furthermore an alloy containing 15% Cr, 5% Al, 1% Nb, 1% Y, balance Fe and dispersion strengthened with 4 vol.% Al 2 O 3  was rolled at 1800F and then heated to 2425F by passage of a 1500F/ inch temperature gradient at 1 inch/hour. Suitable apparatus for carrying out the invention comprises a planar induction coil 10 and water cooled chill block through which a workpiece 20 is passed. The power supply to the coil is controlled by optical pyrometer 26. The process may be applied to turbine blades.
