Title: Improvements relating to textile draw twisting or draw winding machines
IPC: D02J1/22
Filed: 1963-12-31
Abstract: For a draw-twisting or draw-winding apparatus in which yarn passes from a drawing-roller around a separating-roller and back to the drawing-roller, the separating-roller is mounted to swing towards and away from the drawing-roller and is resiliently urged to swing away from the drawing roller by a force less than that exerted on it by the thread In Fig. 4, (not shown), the separating roller 31 is mounted on an arm pivoted on a fixed part and is urged away from the drawing roller 21 by a spring 26, stops 24, 25 being provided.  In Fig. 3, (not shown), the separating roller is on an arm 18 mounted on a fixed part by a spring 15.  When the thread breaks &c, contacts are closed by movement of the arm to actuate an alarm.

Abstract: 1,138,578. Producing radio-active substances. SANDERS NUCLEAR CORP. 14 Nov., 1967 [2 Dec., 1966], No. 51849/67. Heading G6P. Thulium 171, for use in an isotopic power source, is produced by neutron irradiation within a nuclear reactor of thulium 169. The metal or oxide of thulium 169 are used in powdered or sintered form and compressed to near the theoretical density. After neutron irradiation, the material is removed from the reactor and the thulium 170 and 171 products allowed to decay. Subsequently, a separation of the residual thulium products from ytterbium is effected by an ion exchange process. As thulium 170 and thulium 171 decay at different rates the ratio of the atomic percentage of the two may be selected by determining the required decay period.

Title: Method of and apparatus for producing split fibrous material
IPC: D01D5/42
Filed: 1966-11-25
Abstract: 1,126,759. Artificial fibres and filaments. MITSUI PETROCHEMICAL INDUSTRIES Ltd. 25 Nov., 1966 [27 Nov., 1965; 15 Nov., 1966], No. 52959/66; Heading B5B. [Also in Division D1] Split fibrous material having uniformly sized meshes is produced by stretching a tape of thermoplastic organic synthetic polymer longitudinally at a stretch ratio of 3 : 1 to 10 : 1, and slitting the tape so that a plurality of sets of slits are obtained parallel to the direction of stretch, each slit in a set being spaced substantially equidistant from the next, and each set being staggered a small distance transversely from the preceding set such that the sets overlap in the longitudinal direction, and stretching the slit strip in a direction transverse to. the longitudinal direction of the strip to obtain a netlike structure of relatively thick fiaments of a size between 15 and 50 deniers, and relatively thin filaments of a size appreciably thinner than the thick filaments but between 3 and 15 deniers. An apparatus for carrying out the process comprises two pairs of nip rolls with a slitting member mounted between them which rotates in the same direction as the moving tape and at a greater speed, the surface of the slitting member having a plurality of sets of slitting blades disposed parallel to the circumferential direction and spaced substantially equidistantly from each other in the axial direction, each set being disposed such that the " file " of the blacks (defined) is successively staggered a small distance transversely of that of the preceding set, the sets being in spaced relationship to each other in the circumferential direction. Several types of slitting members are described. In one embodiment the split fibre may be crimped by passing the stretched tape through at least one pair of heat embossing rolls before slitting as above, and then heat shrinking the split fibre to impart crimps. Yarn-like material may be produced by spreading out the split fibre, cutting it at intervals along its length, and thereafter twisting each portion of the cut split fibre. Polyolefins such as polyethylene or polypropylene, are the preferred polymeric material used.

Title: Alarm systems

Abstract: 1448029 Alarm systems WORMALD INTERNATIONAL Ltd 19 Nov 1973 [20 Nov 1972] 53609/73 Heading G4H [Also in Division H3] In an alarm system, remote stations each include a plurality of constant current sources connectable in a line to a central station to signal alarm/normal conditions, electronic means scanning the lines and connecting them in turn to an impedance the voltage across which is measured to give an alarm if appropriate, there being means for identifying the line being scanned, and the scanning cycle being continuously repeated. At the central station, 100 such lines are scanned by two decades of a BCD counter, each decade being decoded to 1-out-of-10 form for this purpose. The line current is compared with a staircase voltage produced by a clock-driven counter and a D/A converter to determine the line status. Of 8 possible current levels, the highest and lowest are used for line fault monitoring, one is used to indicate "normal" and 5 are alarm levels. Non-normal levels are checked 4 times to avoid error. The count at equality (identifying the level and thus the status) is stored in binary and 1-out-of-8 form together with a "normal/not-normal" bit, to feed an output together with the line addresses. Storage is blocked if there is no change of status from the previous scan, determined by storing the "normal/not-normal" bits in a memory at addresses corresponding to the line addresses and comparing the bit valves with those in the next scan to indicate "same", "transition from normal to not-normal", or "transition from not-normal to normal". (Alternatively, all status transitions may be detected). Specification 1,448,028 which is referred to, has essentially the same disclosure.

Abstract: 1,196,450. Filling receptacles. P. J. L. SEQUEIRA. 27 Feb., 1969 [30 Nov., 1967], No. 54474/67. Heading B8T. A filling machine comprises a carriage 8 adapted to support more than one receptacle 10, sliding below at least one outlet 13 on a track 7. The carriage 8 is spring loaded to move toward one end of the track, progression being controlled by an escapement mechanism in sequence with the operation of a pump supplying a predetermined volume of liquid to the receptacles. In a particular embodiment the escapement mechanism includes a pair of pawls 19, 20, Fig. 2, controlled by a solenoid 23, which pawls interact with a crenellated bar 21. Engagement of the pawl 20, biased by springs 22, with the bar 21, causes the operation of a switch 25 which starts the pump delivering liquid and, after a predetermined delay, the operation of the solenoid and subsequent disengagement of the pawl 20 from the bar 21. The spring-loaded movement of the bar is almost immediately checked by the other pawl 19, not however before the spring 26 has moved the hinged plate 17 and opened the contacts of the switch 25. This de-energizes the solenoid and the metering pump, allowing the springs 22 to disengage the pawl 19 and bring the bevelled pawl 20 in front of the next tooth on the bar. In a modification, the intermittent motion of the carriage is caused by the controlled operation of a synchronous motor (31), Fig. 4 (not shown), which relieves tension in a spring (28), opposing the spring loading of the carriage, through a freewheel device.
