IPC: D02J1/18
Abstract: 1,050,766. Collagen multifilaments ETHICON Inc. Aug. 8, 1963 [Aug. 10, 1962], No. 31353/63. Heading B5B [Also in Division D1] Adhering collagen monofilaments in a multifilament bundle are separated by imparting to the bundle, between two fixed points, a variable longitudinal tension. Lateral adhesions are thereby broken so that an " open " multifilament results. In an open multifila- -ment the - individual monofilaments are uniformly separated and have lateral and longitudinal freedom of motion. The term " monofilament " is defined as a single thread of oriented collagen fibrils as extruded through a single orifice of a spinneret. The variable tension is applied by contacting the bundle, as it travels at constant speed between two fixed, spaced guides, with a member reciprocating in a direction parallel to :the direction of travel of the bundle. In one embodiment (not shown), a dried collagen multifilament travels at constant speed from creel spool 2 via godets 3 and 4, and fixed, spaced guides (revolving pulleys) 5 and 9, to take-up spool 10. Between guides 5 and 9, the multifilament is frictionally engaged by porcelain rods 6, 7 and   8 mounted on block 12 supported by rod 13. Revolving wheel 15 and connecting rod 14 cause rod 13 to reciprocate in bearings 17, 18 and thus an alternate increase and decrease of tension is applied to the filament bundle between guides 5 and 9. The multifilaments may be made by spinning into a dehydrating bath a dispersion of swollen, enzyme-treated collagen fibrils in cyanoacetic acid, water and methanol. The spun filaments are tanned, stretched and dried.

A logic circuit operating in response to a predetermined combination of inputs I 1 , I 2 , I 3 , comprises a transistor T and tunnel diodes TD1, TD2 connected as shown and subjected respectively to trigger and polarizing currents 1<SP>1</SP>T, I<SP>1</SP>O and IT, IO. The trigger currents are repetitive and successively of opposite sign and are superimposed on the steady polarizing currents, the values of the currents being so chosen that tunnel diode TD1 is switched successively between its high and low-voltage states but tunnel TD2 is switched to its lowvoltage state only, the trigger current IT being insufficient to effect switching from the low to the high voltage state unless input currents I 1 , I 2 , I 3  totalling sufficient magnitude are also applied to tunnel diode TD2. Transistor T thus periodically conducts for inputs I 1 , I 2 , I 3  less than a certain magnitude but does not conduct for inputs in excess of that magnitude. Figs. 3-8 (not shown) illustrate combinations of more than one of the above circuits, together with at least one delay line, operating as pulse frequency dividers, the delayed output from one circuit so controlling the output from another circuit that the desired frequency dividing effect is achieved.

Abstract: 1,230,410. Hydro-mechanical variable-ratio epicyclic gear. T. TSURUYA. 23 Aug., 1968, No. 40428/68. Heading F2D. An automatic variable-ratio split-torque transmission, for motor vehicles or construction equipment, comprises a sun-ring train having a carrier 43 fast with the transmission output shaft 44, a sun 42 driven from the transmission input shaft 1 through a shaft 10, and a ring 39 driven from the input shaft 1 through a torque converter 3-5, a hollow shaft 7 and a planetary three-speed gear. The latter provides Low, Intermediate and "1/1" drives therethrough and comprises planets 18 carried by a double ring 28 and meshing a ring 19 and a sun 17 fast on the shaft 7, planets 27 carried by a sun 34 and meshing the double ring 28 and a sun 26 also fast on the shaft 7, and planets 36 carried by the ring 39 and meshing the sun 34 and the double ring 28. One-way brakes 20, 29 respectively acting on the rings 19, 28 to provide Intermediate and Low are rendered effective by brake-bands 22, 33. The torque converter reactor 5 reacts on a one-way brake 8. The torque converter pump 3 drives an oil pump 12 which together with an output shaft oil pump (not shown) is used to provide a gear control pressure differential. Operation.-In Low, with the band 33 applied, initially, under high load, the output shaft 44 and the carrier 43 are held and, in consequence, the converter turbine is rotated reversely against converter fluid friction. As output load is decreased and the output shaft rotates forwardly, the turbine rotation changes to forward. In shift from Low to Intermediate, on application of the band 22, the one-way brake 29 releases. It is stated that on release of the band 22 the planetary three-speed gear rotates solid at 1/1 ratio. In addition to "normal" engine braking, a brake band 40 may be applied to the ring 39 for increased engine braking; further, this band may also be applied for short-distance startermotor vehicle propulsion.

[Also in Division F2] In a method of hydraulically pressure testing a vessel 10 having a plurality of tubular connections 12 to the vessel wall (only one such connection being shown), an access aperture 24 is opened, sealing plugs 50 are positioned from the interior of the vessel to isolate the connections to the vessel, the access aperture is sealed, and liquid introduced into the vessel to apply internal pressure thereto. The vessel, 10, Fig. 1 (not shown), is a re-heater driven through which re-heated steam passes after passage through a tube bank 4 of a steam generating super-heating and re-heating unit 2 of a turbine 6. Initially, a dome cap 70, which is normally welded to the end of a tubular member 66 defining the access aperture, is cut away to permit an operative to enter the drum. Seal plugs 50 are then passed through aperture and locked in position to obturate each tube connection. Each plug has a frustoconical face 54 having a sealing ring (not shown) which sealingly engages a frusto-conical seat 30 of a respective stub nozzle 22 welded to the vessel and tubes 12. The plug is secured by a bar 62 which is fixed to the rear of the plug and engages a pair of threaded studs 48 welded to the internal wall of the vessel. The operator then draws an internally mounted door 78 against the inner end of the member 66 as he leaves the vessel. The door is locked in position by bridging pieces 104, which are drawn against the outer end of the member by studs 100 threaded into the outer face of the door. The inlets to the distributer 9 are sealed as by cutting the tubes and inserting plugs. Water is then introduced into the tube bank 4 and drum 10 and pressure applied to test the integrity of the tube bank and drum. After testing, the water is drained and studs 100 removed.

Abstract: 1,231,335. Selective printing. ING. C. OLIVETTI & C. S.p.A. 1 April, 1969 [23 April, 1968], No. 17085/69. Heading B6F. [Also in Division G4]  In a printer a type-wheel is moved to a selected position by entering the complement of the desired position into a counter, incrementing the counter by clock-pulses produced inductively as the type-wheel rotates, and clamping the wheel when the counter becomes full. As described the complete fount of type is spread over four type-wheels 1, Fig. 1. A character is selected by causing one of the four wheels to move to a central fixed printing position and by causing the print wheels to rotate into an appropriate angular position. Subsequent printing is then effected by causing a hammer 77 to reciprocate so as to impell a slide 4 carrying the selected print-wheel towards the paper, which is carried by a movable platen 38. The printer can be controlled either by keys, or by electric signals from an external source, in which case the keyboard is locked by engagement of a tab (251, Fig. 8) with the key lever shanks (107). Input signals 161, Fig. 5, are recoded at 163, the resulting top four bits A, B, C, D are complemented at 169 and entered into a counter 170 to determine the angular position of the type wheels and the last two bits E, F, are recoded to select one of the four type wheels and to cause it to be moved to the printing position. As the type-wheels rotate, inductively produced pulses at 178 advance the counter 170 until it is full whereupon a solenoid 174 is energized to clutch the print wheels in the appropriate position. Subsequently, at a fixed time in a machine cycle, hammer 77 is actuated by a spring 81. On completion of a cycle, the hammer 77 is returned by a lever 27 acting on a lever 79. A second counter 182 is provided to provide various reset signals at the end of a cycle and to cause the next character to be fed in.
