Title: Improvements in punching device for roller bearing cages and similar articles
IPC: B21D28/30
Filed: 1932-05-18
Abstract: 400,316. Making bearing-cages. STRICKLAND, S. A., 1405, Balmoral Avenue, and BOWER ROLLER BEARING CO., 3040, Hart Avenue, both in Detroit, Michigan, U.S.A. May 18, 1932, No. 14138. [Classes 83 (ii) and 83 (iv).] Punching ; punches. -A. series of perforations 14 is formed in a bearing-cage 15 or other annular article by a number of non-pivotal punches supported and guided for bodily rectilinear movement in a member which is movable vertically into and out of the plane wherein the punches are brought into operative engagement with the work. The head 1 of the device, actuated by the vertically movable ram of the press, has bolted thereto a guide ring 3 in which is slidable, but non-rotatably guided by keys 5, a block 4 preferably split as shown and providing guideways for the arms 10 of punching tools 13. The blank 16 is supported on a die block 20 bolted to the base plate 21. The parts are shown in Fig. 1 at the. conclusion of the punching operation in which the tools 13 have entered co-operating passages 24, through which the punched out portions pass. At the commencement of the operation the head 1 is raised, and the block 4 separated therefrom by the action of springs 7. On downward movement of the head, the block is lowered to seat on the die block 20, further downward movement then compressing springs 7 and causing a spreader 33 to force the tools radially outward to form the holes, as in Fig. 1. On return movement of the head, an ejector 25 is raised by a spring 28, the punches being retracted during relative movement between members 3, 4, when an inclined surface 19 on each punch is engaged by the inner surface of the ring 3. Forging; dies.-The edges of the perforations 14 are bevelled in a similar machine, in which the tools comprise operative portions 42, Fig. 6, of the form shown. A resiliently held gauging-member 41 enters one previously punched hole 14 to locate the work. The spreader 33 in this machine carries an extension which depresses the ejector cup at an early stage of the operation to ensure free engagement of the work with the member 41.

Abstract: 1280077 Automatic exchange systems GENERAL ELECTRIC CO Ltd 19 April 1971 [24 March 1970] 14229/70 Heading H4K Channel selection for connections in a system of exchanges interconnected by time-division multiplex highways is effected on the basis of channel availability data transmitted between the exchanges in order to reduce the need for time slot changing between inlets and outlets of an exchange. Channel data may be sent between exchanges using signalling channels on the highways or separate inter-exchange links may be employed. Each exchange may collect channel availability data from surrounding exchanges; or one exchange of the system, permanently or by temporary nomination, may accumulate channel data for the system and be consulted by any exchange requiring a connection. In the system described, program-controlled exchanges may be purely transit exchanges or may serve satellite switching centres (non-exchange) each connected over at least two highways and serving a maximum of 981 subscribers. The highways are provided with 32 PCM channels, one channel being set aside for signalling and another for synchronization. The satellites comprise two stages of gating, groups of 31 lines being gated to satellite highways, and 31 such highways being gated to the main exchange highways. The main exchangers provide zero, fixed, or variable delay cords on a 4-wire highway basis, the cords being accessed as links of a folded interhighway switching network. In one network, Fig. 3 (not shown), the delay cords are strapped to couple the outlets of the second of two stages of switching matrices, the inlets to the first stage serving incoming and outgoing interexchange highways. In this network the cords may need to be reversed according to the disposition of incoming and outgoing highways in a connection. In a second network, Fig. 4 (not shown), incoming highways are connected to delay cords distributed over half the outlets of a second stage of matrix switches, a third switching stage coupling the delay cords back to the other half of the second stage outlets to complete a connection back to an inlet of the first stage. In this network the cords are always connected in the correct direction and require no reversing facility. The networks can be expanded by doubling the co-ordinate dimensions of one switching stage and doubling the number of switches in the other stages. If in establishing a connection between exchanges a change of time slot is necessary it is said to be preferable if such a time slot change is made to occur at a transit exchange unencumbered by satellites.

Abstract: 361,292. Submarine subways. PREVOST DE SAINT-CYR, G. P. J., 30, Avenue de Neuilly, Neuilly, Seine, France. May 10, 1930, No. 14467. Convention date, May 11, 1929. Void [Published under Sect. 91 of the Acts]. [Classes 68 (ii) and 85.] A submarine subway for railways or roads consists of a number of tubular elements, preferably of concrete, which are fitted with temporary terminal shields, launched, sunk in alignment, and jointed. Fig. 1 shows such a subway, of which a part 2 lies on the sea bottom, a part 3 is tunnelled, and a part 1 is supported on piers 4. The elements 5, 6, Fig. 2, are connected by sleeves 7, and their ends are fitted with temporary shields S, 9, which may be in the form of manhole covers. In the making of the joint, a sleeve of ice may be formed round the ends of the elements by circulating cold gas or brine through tubes round them : or temporary non-rigid joint sleeves may be used; inside these permanent joints may be made. In a modification, a sleeve joint 7 is rendered temporarily watertight by inflating pneumatic tubes ; a permanent joint is then made inside it. The elements are slung on cables 60, 61, Fig. 12, which are passed through eyes 62, 63 on the elements ; the ends of the ropes are attached to winches on service boats, which gradually lower them into position. To bring them into alignment, caissons 81, Fig. 21, are set on the sea bottom. Its above-water end has a platform 87, with winches 89, by means of which the element 96 is lowered. Chains 92 with tensioning devices 93 facilitate the adjustment. Two caissons 81 are brought into alignment by means of two service anchored boats, anchored rafts 106, Fig. 20, and submerged caissons 102 connected to the rafts by flexible tubes 112 and chains 103. Each part 106, 102 has propellers 107, 108. For building the piers 4 on which the sections are to rest, there is provided a mould box consisting of four sides 114, Fig. 14, on adjustable feet 115 secured by screws 117. To raise or adjust the box, a pressure cylinder 121 is connected to it by links 123, and pressure fluid is admitted by a pipe 122. The cylinder rises on the piston 120, and resets the mould, which is then filled with concrete. Similar devices connected by a beam are used for aligning preformed structures for foundations.

Abstract: 838,008. Electric lamp supports. LIGHTOLIER Inc. May 6, 1958 [June 14, 1957], No. 14481/58. Class 75(3) [Also in Group XXXVI] A floor to ceiling post 11 (Fig. 1) having a spring-urged upper end 12 and an adjustable lower end 12<SP>1</SP> is provided with side flanges 16 (Fig. 2) which, with side walls 15 and lips 17, 18, form a divided enclosure, the rear part of which accommodates conductors 22 held in a resilient extruded insulating strip 21 and the front part of which accommodates locking flanges 26, 27 of a plug member 25. The contact fingers 39, 41 of the plug member are brought into connection with the conductors 22 when the plug is turned to bring its slightly flexible locking flanges 26, 27 perpendicularly across the slot formed by lips 17 through which they were introduced. Conducting strips 37, 38, which have stuck out portions 45 and which are bent at the ends to form the plug contact fingers 39, 41 are clamped by a plug insert 32 the end of which is bevelled to permit inward displacement of the contact fingers 39, 41. The housing 56 of the plug incorporates a face plate 58 (Fig. 5) with top and bottom projections 61 which fit in the slot between lips 17 and prevent rotation. Rotation of the plug 25 and the attached insulating sleeve member 48 through 90 degrees to turn the contact fingers and locking flanges 26, 27 across post 11 after insertion through the slot therein is produced by moving a headed screw 67 which passes through a slot 66 in housing 56 and a hole in plug 25 into a threaded bore in insert 32. This screw is screwed further in when the plug is in contact position, the head then entering hole 65 and, since it is wider than slot 66 preventing return rotation of plug 25. The slot 66 is inclined so that rotation of plug 25 into contact position causes locking flanges 26, 27 to grip the lips 17 of post 11 against plate 58 of housing 56. A dimple 62 in housing 56 co-operates with grooves 63, 64 in plug 25. A lamp 47 is mounted through sleeve 73 (Fig. 5) on the reduced portion 72 of plug housing 56.

Abstract: 529,311. Making extracts. DU PONT DE NEMOURS & CO., E. I. May 15, 1939, No. 14500. Convention date, May 13, 1938. [Class 81 (i)] [Also in Group III] In the continuous extraction of oil, fat, or wax by treating solid material in counter-current with solvent of higher S.G. than the oil, fat, or wax, the solvent first flows downwards for a relatively short distance and then upwards at a small angle to the horizontal for a comparatively long distance, the solid being moved in the opposite direction ; liquid of lower S.G. is thus always maintained above liquid of higher S.G. Solid materials specified are seeds, beans, tubers and animal matter; they may be pretreated e.g. mechanically or by steam to facilitate extraction. Suitably, soya bean flakes are passed down a plain or jacketed extractor tube 2 inclined at 10-25 degrees and up a short tube 3 inclined to the vertical at 0-25 degrees either toward or away from the tube 2, while tri- or perchlorethylene is passed in by a tube 11 and extract passed out through slots 12, a screen 15, and a pipe 14 leading to a stripping still. The treated flakes fall through an outlet 4 and are passed through a steam-jacketed drier 21, a steamer 22, and a barrel valve 43 to storage. The drier and steamer may be different sections of one long tube ; there may be a plurality of drier and steamer sections ; the flakes are preferably heated to at least 100‹ C. before contact with the steam ; superheated steam or other gas may be injected directly into the steamer through one or more inlets 41 ; the slots 12 may be automatically cleaned by flexible wires suitably spaced along the shaft of the conveyer 5; a cup tyre extractor may replace the extractor 5 ; the conveyer in the tube 3 may have perforated flights to facilitate drainage of solvent from the flakes, and the upper flights 8 are preferably reversed to facilitate discharge of the flakes into spout 4 ; conveyer 24 of the drier has solid flights 25 at the front and reverse flights 29 at the discharge end, and in the centre flights consisting of 2 rods wound round the central shaft to form spirals 26, 27 of different pitch and spaced from the shaft by struts 28 ; the conveyer 32 of the steamer has solid reversed flights 35 at the outlet end, but otherwise consists of a rod spiral 33 supported by struts 34 and with adjacent flights connected by horizontal bars 38, preferably 2-3 flights on one side alternating with 2-3 on the other ; either type of open conveyer 24, 32 may be used in the drier and/or steamer; and the extractor may be emptied through a drain 16 which also serves as a sump for small pieces of metal or other undesired matter.

Title: Operand comparator
IPC: G06F7/02
Filed: 1974-04-03
Abstract: 1453769 Comparators AMDAHL CORP 3 April 1974 [14 May 1973] 14793/74 Headings G4A and G4M An operand comparator (Fig. 2) for comparing first and second operands OP1=a(0) ... a(31), OP2=b(0) ... b(31) includes first apparatus for simultaneously comparing corresponding bits in the operands to determine the highest order equality relationship between bits and second apparatus for simultaneously comparing corresponding bits to detect the highest order non- equality relationship between bits. The comparator may be used to establish logical relationships between positive and negative numbers in fixed point or floating point format. The comparator comprises a series of stages. Stage 1 derives, from its inputs, bipolar outputs which are operated on in stage 2, the latter stage including circuitry for performing an exclusive OR function, and an exclusive NOR function for each bit, determination of the sign of the operands and an OR function for each bit. In the third stage the outputs of selected ones of the second stages are NANDed and fed to a fourth stage IV-1 where a determination is made of whether the first bit position at which the first operand differs from the second operand has a "1" bit in the first operand. Stage IV-2 determines whether every bit position of the two operands differs. Stage IV-3 determines whether the first pair of identical bits are both "1". Stage IV-4 determines whether the two operands are identical apart from sign and stage IV-5 produces output signals which specify that certain bits of both operands are zero. Stage V determines inter alia whether the absolute value of the first operand is greater or equal to the second operand and whether, with operands of different sign and having first similar bits "1", all subsequent bits are "0". The signals from stages I-V are processed in stages VI-VIII to calculate whether predetermined equality relationships exists between OP1 and OP2 and to derive latch signals if overflow conditions exist when OP1 and OP2 are logically combined.
