Title: Data comparator
IPC: F15C1/10
Filed: 1963-10-07
Abstract: 976,038. Statistical apparatus; fluid logic elements. SPERRY RAND CORPORATION. Oct. 7, 1963 [Oct. 18, 1962], No. 39428/63. Headings G4B and G4M. A system for comparing date. recorded on two record media 13, 15 comprises a source 1 supplying fluid under pressure to two sensing stations 3, 5 and an exclusive OR fluid logic element 7 controlled by the sensing stations. The index positions on the record media may be sensed simultaneously, or row-by-row, or column-by-column, and a logic element 7 is provided for each index position sensed at a time. The presence of a hole in medium 13 produces a power jet stream in fluid amplifier 29a and a control jet stream in amplifier 29b. Similarly a hole in medium 15 produces a power jet in amplifier 29b and a control jet in amplifier 29a. If the data sensed from corresponding positions in the record media are different, an output is obtained in duct 41 to operate an error indicator and/or a feed control device or sorting mechanism. Chambers 53a, 53b delay the power jet streams until after the control jet streams have been established.

Title: Device for forging a crankshaft
IPC: B21J7/14
Filed: 1968-08-21
Abstract: 1,205,063. Forging. COMPAGNIE DES ATELIERS ET FORGES DE LA LOIRE (St. Chamond Firminy, St. Etienne, Jacob- Holtzer). 21 Aug., 1968 [7 Sept., 1967], No. 40021/68. Heading B3H. A crank-shaft forging press comprises a central tool 14 mounted between the platens 1, 2 with dies 13a, 13b which are closed around a blank disposed vertically in the press to offset a portion of the blank between parts gripped by dies 3a, 3b, 4a, 4b as the platens are brought together to upset the blank on each side of the tool and as the tool is moved horizontally. The lower platen 1 is fixed and has a pair of pistoncylinder units 6 operating on a cross-beam 10 to which columns (9), Fig. 3 (not shown), are secured. The upper platen 2 is fixed to the columns and the central tool is transversely slidable in a cross-member 5 slidable on the columns by a piston unit (19) operating through linkages (17), (18). The dies 3a, 3b, 4a, 4b are closed by piston-cylinder units 7, 8 to grip the blank at positions for the crank-shaft journals. The dies 13a, 13b of the central tool are closed by piston-cylinder units 15, 16 and the tool 14 moved by the units 15. The blank may be plain or have constrictions and is heated in a vertical position in a localized action furnace, e.g. induction heating. The heated blank is then transferred by crane into the press by lowering through holes 11, 12 in the platens. The top throw is preferably formed first. Before forging the blank is rotated either in the furnace or the press so as to align the offsetting direction with the desired throw direction. The forging is performed in two steps which comprise, firstly, partially upsetting the blank and completely offsetting the crank-pin portion and, secondly, completing the upsetting and shaping the crank webs in the dies of the central tool 14 and the journal clamping dies 3a, 3b, 4a, 4b.

Abstract: 1,128,997. Change-speed control. DE VLIEG MACHINE CO. 7 Sept., 1966 [7 Sept., 1965; 23 Oct., 1965], No. 40061/66. Heading F2D. [Also in Divisions B3 and G1] In a horizontal boring and milling machine the lead screws 98, 40, Fig. 3, for feeding the spindle head and the work-table, can be rotated so as to selectively move the head or table to a predetermined position, by a gear drive which provides eighteen different speeds. The drive is from a two-speed motor M, Fig. 2, through a chain-and-sprocket drive 52, 54, Fig. 3, to a shaft 56. A direct drive to a pinion 80 is provided through an hydraulic clutch 60, a parallel drive is provided through gears 58, 64, 72, 74 and a second hydraulic clutch 76, and a drive through an eight-speed gear-box 68, Fig. 4, is provided, wherein gear 64, Fig. 3, meshes with an input gear 192 in the gear-box, and an output gear 194 meshes with gear 70. Pinion 80 has dogs 80a, 806 which are selectively engaged with dogs 88a or 84a, so as to drive the lead screw 98 or 40. Gear shifter forks 174,176, 178 in gear-box 68, Fig. 4, clutches 60, 76, Fig. 3, and the gear shifter fork for gear 80, Fig. 3, are actuated by solenoid-controlled valves 150, 152, 154, 134 and 130 respectively, Fig. 7. The spindle head or table may be advanced to the predetermined position in either one of two cycles. In the first cycle, the head or table is moved repetitively back and forth across the required position at successively reduced speeds until it stops at the position, and in the second cycle the member is advanced to the position without overshooting, and is slowed down during this movement. In operation, a position to which the spindle head or table is to be moved is selected on a console (A), Fig. 11 (not shown). The electrical circuit comprises three contacts (K1), (K3a), (K3b), Fig. 9 (not shown), one of which is closed when the member is on the right of the required position, one of which is closed when the member is on the left of the position, and one of which is closed when the member is in position. The actuation of these contacts operates solenoids 1-7, Fig. 7, and also controls the windings of motor M. The head or table is moved to position with clutch 60, Fig. 3, engaged. When the member passes over the required position during the reciprocating cycle, the direction of rotation of motor M is reversed, clutch 60 is disengaged, clutch 76 is engaged, and the member is driven at a slower speed through gear-box 68, and also the slow speed windings of motor M is selected. The member therefore reciprocates, and the gears in box 68 are changed, so that the member eventually stops in the required position.

[Also in Division G3] A workpiece in a copy-milling machine is mounted on a top slide 3 of a compound slide 1 which is longitudinally displaceable in direction 19 along a bed 2 between stops 20, 21. The stops actuate a limit switch 18 controlling a contactor 22 to arrest movoment in the direction 19 through a solenoid valve, not shown, and initiate movement in a transverse direction 6 by opening a solenoid valve 12 to cause oil to flow to a motor 10 driving a feed spindle 7 for the slide 3. Increments of slide movement are sensed by a cam 8 and microswitch 15 which transmit pulses to a counter 16, which at a count representative of a desired spacing between longitudinal movements controls the contactor 22 so as to stop longitudinal movement by actuating a magnetic brake 9 and closing the valve 12. The counter 17 is reset to zero by a magnet 17 and reversal of the direction of movement of slide 1 is effected by a switch 23.

Abstract: The invention comprises a composition which is a heterogeneous mixture of a linear fibre-forming polyester and a copolyamide having a melt viscosity not substantially greater than that of the polyester.  The copolyamides advantageously constitute 1-25% of this composition, and should be soluble in, or softened by, water or water/alcohol mixtures, and have a melting point between 140 DEG  and 260 DEG  C., and an intrinsic viscosity (in 60/40 phenol/tetrachlorethylene at 25 DEG  C.) of 0.6-2.0, with a water absorption at saturation of 7-14%.  Suitable copolyamides are those of 6/66, 6/610, 66/610 or 6/66/610 types, or those containing carbocyclic structures.  In general, no unit should constitute more than 95%, or less than 10% of the copolyamide. The polyesters preferably have an inherent viscosity of at least 0.4, and a melting-point between 150 DEG  and 350 DEG  C.  The polyester and copolyamide are mixed, melted, and spun into fibres before the mixture becomes homogeneous-preferably within 30 minutes of melting. In examples, compositions are prepared from poly-(1,4 - cyclohexylene - dimethylene - terephthalate) and various 6/66 type copolyamides, from poly - (ethylene-terephthalate) or polyethylene-(terephthalate 97% sulpho-isophthalate 3%) and 66/610, 6/66/610 or caprolactam/m-xylylene diammonium adipate or tetramethylene diammonium oxalate/decamethylene diammonium oxalate copolyamides, from polyethylene-(terephthate 90%, isophthalate 10%) and a caprolactam/1,4 - cyclohexylene dimethylene diammonium isophthalate copolyamide, and from a poly-1,4-cyclohexylene dimethylene-(terephthalate/ succinate) or a polypentamethylene - (4,41 - sulphonyldibenzoate/succinate) and a 1,4-cyclohexylene dimethylene diammonium isophthalate/hexamethylene diammonium adipate copolyamide.
