Title: Swab-making machine
IPC: A61F13/38
Filed: 1967-09-05
Abstract: Apparatus for manufacturing surgical swabs consisting of a stick 18 with a fibrous tampon 50 at at least one end comprises (Figure 1) a rotating transport device 12 provided with pockets 16 in which the device receives the surgical sticks from a feeder 20, there being means 26 for rotating the sticks within the pockets, means 34 for supplying loose fibrous yarn, a tuft applying device 40 movable between a position for removing a tuft from the yarn supply and a position for applying the removed tuft to the end of a stick as it rotates in a transport device pocket, and a device for shaping the fibrous tufts at the ends of the sticks, the tuft applying device having two jaws and being arranged to open and close around a tuft, there being means provided for locking the jaws in the opened and in the closed positions. As shown, the sticks are moved in a rotating transport wheel 12 having pockets 16 from which the sticks project at each side of the wheel, the sticks being rotated in the pockets by a disc 26, features of the apparatus being duplicated (although not apparent from the drawings) so that a fibrous tuft of cotton or rayon is applied to each end of each stick. The fibrous yarn is moved from the supply tube 34 onto a supply guide 48 (Figure 2) by a periodically rotated knurled part 46 and is offered to the tuft applying device 40. The tuft applying device 40 comprises a base plate 70 which periodically moves vertically (from the position of Figure 9 to that of Figure 7, not shown) on columns 126 from the apparatus housing 10 so as to offer a tuft of fibrous yarn taken from the low positioned guide 48 to the higher positioned swab stick and the swab shaping device 52. Mounted on the base plate 70 are two jaws 72 which close under the action of a compression spring 86 and a peg and shaped slot arrangement 78, 76 to grip the tuft when the tuft applying device is adjacent the guide 48. The slots are said to be shaped so that the jaws are effectively locked respectively against an opening or a closing movement when in the fully closed or opened positions. The jaws are substantially opened by arm members 102 which are driven about a pivot (104) in the housing 10 when the tuft applying device is adjacent the shaping device 52 and act so as to move the pegs 78, there being a spring loaded locking device 96 which assists in retaining the jaws in the open position until such time as it is released by a peg (128) when the tuft applying device has redescended. The tufts are applied to the swab sticks (Figures 4-6, not shown) in the tuft shaping device 52 which is provided with a surface 62 suitable to give the tufts rotating on the sticks a 'drop' shape, the shaping device including a supply 54 of water or glue which is applied to the swab.

Title: Spindle Rotor of a Two-for-One Twist Spindle
IPC: D01H7/86
Filed: 1967-09-26
Abstract: The spindle of a multiple part two for one twisting spindle is provided at the level of a yarn disc 16 with a transverse recess 7 into which a shaped part is inserted, the shaped part consisting of two plastics matching parts 8 and 9 with an intermediate matching part 10 made from wear resistant material e.g. sintered corundum housed therebetween. The parts define between them a curved yarn guide channel 11 inside which yarn entering vertically in the centre from stationary tube 4 is deflected along the curved path of the channel into the radial direction. When part 10 becomes worn due to yarn rubbing against it can be replaced by merely removing part 9 from the recess. The parts 8 and 9 are preferably made from flexible plastics material such that when inserted in the recess they are held in position by slight deformation. Matching surfaces 12, 13 are roughened or formed with small knobs, grooves or fins to compensate for slight measurement tolerances. The shaped part may define two curved guide channels in which case it consists of a symmetrical plastics lower part and the upper plastics matching parts of identical shape which between them house a symmetrical intermediate part of wear-resistant material, (Figs. 5 and 6).
Patent ES-346858-A1 (ES)
Title: Reducing the Corrosion of Graphite in Nuclear Reactors
IPC: G21C1/12
Filed: 1967-11-07
Abstract: A method for reducing the graphite corrosion in a graphite - moderated, CO 2 -cooled nuclear reactor is characterized in that a flow of coolant containing a gaseous corrosion inhibitor is forcibly circulated inside the pores of the graphite. Suitable inhibitors include CO, H 2 , light saturated hydrocarbons (e.g. methane) and oxygenized hydrocarbon derivatives (e.g. acetone). In one embodiment, a reactor core is formed of graphite blocks 6 assembled in columns connected by keys and separated by clearances. Each block 6 has a vertical channel 4 opening at its lower end in a debris collector 10 having openings 12 for the CO 2 which flows along the channel as indicated by the arrows f. Each channel 4 locates a set of fuel cartridges 16 each having a graphite sleeve 18 and a fuel element 20, the latter consisting of a tubular slug of slightly alloyed uranium with a protective coating on its inner and outer surfaces, being retained in the sleeve 18 by an annular saddle 22 connected to the sleeve by retaining wires. Partitions 24 centre the fuel element 20 in the sleeve 18. The local head loss #P due to the collector 10 is so selected as to avoid excessive aerodynamic forces on fuel elements during the unloading of a channel. By-pass ducts 26 parallel to the channels 4 are formed between adjacent blocks 6 and open into the coolant collecting space downstream the core through nozzles 28 providing a head loss #P considerably higher than #P. At any predetermined level, a pressure difference exists between the channels 4 and the ducts 26 resulting in a small flow of CO 2 loaded with inhibitor through the pores of the graphite blocks, as shown by arrows f1. This flow tends to maintain the inhibitor content of the CO 2 in the graphite pores at a value near that which prevails in the remainder of the coolant circuit. Protection of the sleeves 18 against corrosion is not always necessary since they stay in the reactor for a relatively short time. If, however, it is preferred to force a coolant flow radially through the sleeves, an annular space between the sleeves and the channel wall is connected to the space downstream the core by restricted passages 34 providing a head loss #P1 whose value is between #P and #P. The invention may be used in reactors other than those employing non-enriched uranium metal as fuel, in particular it may be used in reactors in which the fuel elements comprise bundles of fuel pins employing enriched UO 2 as fuel.

Title: Hyperbolic radio navigation systems of the phase comparison type
IPC: H04B1/06
Filed: 1968-08-17
Abstract: A receiver, for use with a hyperbolic radio navigation system in which synchronized signals of frequency pf and nf are radiated simultaneously from spaced transmitters, each frequency being radiated by only one station at a time, p and n being different integers greater than twelve and f a fundamental frequency, comprises an oscillator at a frequency mf where m is an integer greater than twelve (and may be the same as or different from p and n), means for synchronizing the oscillator with a received signal of frequency pf, a frequency divider providing a time index at frequency f and locked to the oscillator, and a timer responsive to the interval between the time index and a next succeeding time index locked to the nf signals. By integration ambiguities may be resolved. In one embodiment spaced transmitter signals on 1891f, 1887f and 1881f (e.g. f = 37À5 c/s.), Fig. 1, are phaselocked to respective oscillators 14, 15, 16 despite any interruptions in reception (e.g. the transmissions may be deliberately switched). Divider 20 produces an output at f with rectangular waveform and from which an index pulse, shorter than the duration of an R.F. cycle, is afforded by shaper 21 to start a counter 22. The counting is stopped by a squarer 24. Counter 22 is periodically interrogated and the changes in time difference are integrated. A second position line is given by operating switch 26. In another receiver, for stations transmitting on 57f, 56f and 54f, each channel has an oscillator operating at 55f, a gated discriminator controlled from a 55 times divider fed from one oscillator, and integrating meters comparing the phases of the oscillators in pairs, Figs. 2, 3 (neither shown). In a further receiver, Fig. 4, one oscillator only, 55, is utilized for systems in which the transmissions are effectively uninterrupted, phase quadrature outputs are obtained from circuits 60, 65 each of which may comprise the circuit, Fig. 5, which is stated to give substantially 90 degrees phase shift over a wide frequency range: it consists of a transistor 71 affording a constant current to the emitter of transistor 70 the latter being connected to a high input impedance transistor 72 and a capacitative load 73, the emitter of transistor 74 being fed from the collector of transistor 70 and a collector 74 voltage made equal by resistor 75 to that of the voltage at the emitter of transistor 70 but in phase quadrature therewith. Substantially equal amplitudes are obtained but to maintain this when a frequency is changed the magnitude of either load 73 or resistor 75 must be altered.
