Title: Improvements in or relating to the production of crimpable synthetic yarns
IPC: D01D5/34
Filed: 1965-06-10
Abstract: 1,103,728. Synthetic filaments having crimp potential. SNIA VISCOSA SOCIETA' NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA S.p.A. 10 June, 1965 [19 June, 1964], No. 24583/65. Heading B5B. A composite filament having a potential crimp is produced by bonding together in sideby-side relationship at least two mono-filaments at least partially formed by two synthetic polymer components differing from one another in their shrinkage characteristics when heated or in the extent to which they swell when contacted with a swelling agent, at least one of the monofilaments being itself a composite filament having a sheath-core structure, the core component of said composite filament differing in its shrinkable or swellable characteristic from the single polymeric material of the other monofilament, if the latter is a homofilament, or from the core component thereof if said other monofilament is also a composite filament of sheathcore structure, the sheath component of the first composite monofilament being the same as or similar to the single polymeric material or to the sheath component of the said other homofilament or respectively composite filament, so that the two monofilaments will be firmly and permanently bonded together at their interfaces when they are contacted to form the final composite filament owing to the compatibility of the polymers constituting the contacting portions of the individual monofilaments. The components of the final composite filaments may be bonded together by melt-spinning through at least two adjacent orifices of a spinneret two monofilaments and causing these monofilaments to contact one another along their length immediately after they leave the spinneret and while they are still molten so that they become bonded together along their length. Alternatively the components of the final composite filaments may be contacted while they are in the form of melts in a duct of a spinneret prior to extrusion simultaneously through the same spinneret orifice under non-mixing conditions. As shown in Figs. 5 and 7, a spinneret suitable for the process of the invention comprises a spinneret plate 10 provided with pairs of adjacent orifices 18, 19, which are supplied from the central chamber 13, duct 15 and annular chamber 16 with a polymer B. In addition the orifices 18 are supplied with a different polymer A from an annular chamber 14 through the nozzles 17 to form the core component of the composite sheath-core monofilament extruded through the orifices 18. In the spinneret shown in Fig. 9, the polymer B is fed through the separate passageways 21 and 22 which converge to the spinneret orifice 20. The polymer A is injected into the stream of polymer B flowing through the passageway 21 by means of the nozzle 23. The cores of the monofilaments may consist of the same or different polyesters and their sheaths of the same or different polyamides.

Title: Method of and apparatus for recording and reproducing television and like wideband signals
IPC: H04N1/00
Filed: 1961-07-07
Abstract: 977,396. Television and radar signal recording. FERNSEH G.m.b.H. July 7,1961 [July 7, 1960], No. 24647/61. Heading G5R. [Also in Divisions H1 and H4] Records of signals containing regularly repeated portions of constant information such as television line-pulses or the operative pulses of radar T/R switches are made by bombarding a photographic film or ferro-electric tape 11 with an electron beam swept transversely of the tape by a waveform Fig. 4b and pulse-modulated in one of several manners (Fig. 6 not shown) so that two complete cycles of the signal, Fig. 4a are recorded in one track. With the usual interlaced television signal, every fourth line of a frame will be adjacent as indicated by the integers 1-8 in Fig. 5. On playback, alternate pulses are readily recovered from the track-portions 15-17 but the intervening pulses, recorded in part at both ends of the track are subject to elision. Accordingly, a delay-line of characteristic length of two complete cycles is fed with the centre-track pulses, the output being compared with the next-following input pulse to adjust the line characteristics and the intermediate pulses being taken, not from the record-tracks but from the centre of the line and mixed with the remainder of the signal played back in known manner. The film is fed through low-vacuum chambers 31,32 around a drum 13 in an intermediate-vacuum chamber 28,the beam 16 emerging through a slit 35 from a fairly high vacuum enclosure 27,the tube having a tungsten cathode 17 to survive bombardment in the limited vacuum possible. The beam 16 may be bent by known means to prevent light from the cathode from optically fogging the film. Alternatively, a Lenard window may encompass the slot. The slot 35 may have a narrowed portion 35a at one end so that a fixed playback arrangement 37 may interpret the resulting longitudinal square wave-form edge-track to control the record drive or longitudinal deflection of the beam in known manner to centre the beam on the transverse signal tracks.

Title: Beam-controlling systems for tri-colour kinescopes
IPC: H04N9/28
Filed: 1953-09-07
Abstract: 725,525. Colour television tubes. RADIO CORPORATION OF AMERICA. Sept. 7, 1953 [Sept. 17, 1952], No. 24677/53. Class 39 (1) [Also in Group XL (b)]. Relates to an electron beam controlling arrangement for a shadow-mask tri-colour cathode-ray tube 15, such as the tube described in the Proceedings of the LR.E. Vol. 39, No. 10 at page 1194, in which the beam from a single gun 22-24 is subject to a rotating field so as to produce the equivalent of a number of component beams 18, 19 and 20 approaching the mask 17 from different angles. The invention concerns the problem of maintaining the beams convergent at a point in the plane of the mask over the whole of a scanned raster. The rotating field is produced by deflecting means 26 from which the beams emerge divergent and are converged to the plane of the mask by coaxial cylindrical electrodes 27 and 28 energized statically by the potential across resistor 32 in the tube E.H.T. supply. According to the invention the energization of deflecting means 26 is varied as a function of the horizontal and vertical deflection signals so as to vary the beam divergence and thereby the convergence according to the angle of deflection. The deflection means 26 is energized by 90 degrees phase-displaced waves at the system sub-carrier frequency which are obtained from a local synchronized oscillator 28 applying its output through 90 degerees phase shifter 42 to amplifiers 43 and 44. Included between the oscillator and phase shifter is an amplitude modulator 41 to which are applied signals at the vertical and horizontal scan frequencies. A first pair of signals comprise parabolic waves 47 and 48 applied from generators 45 and 46 and in addition a second pair of signals 49 and 50 may be applied in the form of sawtooth waves. Generators 47 and 48 may be of the type described in the Proceedings of the I.R.E. Vol. 39, No. 10 at page 1249.

Abstract: 1,059,297. Measuring electrically. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 15, 1964 [June 13, 1963], No. 24790/64. Heading G1N. A calorimeter comprises three identical cells 12, Fig. 1, each having a thermocouple attached to an identical point thereon, and measures the heat produced in a sample 16 on the central cell when it is subjected to nuclear radiation. The cells all have independent heater windings in grooves on their upper portions, and the powers supplied to the heaters are adjusted to achieve zero reading on a meter 22, Fig. 3 (not shown), which compares the average of the temperatures of the outer two cells with the temperature of the central cell. The difference in the powers supplied to the central cell to achieve zero reading before and after irradiation represents the heat generated in the sample by the radiation. The cells may be aluminium rods, and have hollow upper ends so that a liquid sample may be accommodated, the outer surface being oxidized to insulate the heaters from the rods. An aluminium plate 18 supports the cells and carries terminals for the heaters and thermocouples. The thermocouples may be formed by brazing constantan wires on to the aluminium rods.

Abstract: 737,473. Turbines ; axial-flow compressors. NAPIER & SON, Ltd., D. Sept. 28, 1953 [Oct. 3, 1952], No. 24895/52. Classes 110 (1) and 110 (3). A turbine or axial flow compressor having a guide blade ring assembly comprising inner and outer annular members with angularly adjustable guide blades pivoted therein about radial axes, has non-adjustable guide blades dispersed at intervals between the adjustable guide blades and connected to both the annular members. The hot gases from' an annular combustion chamber or several individual combustion chambers 11 pass through a ring of adjustable guide blades 12 to the turbine rotor. The combustion chambers having a sliding fit in an annular member 16. The blades 12 are adjusted by an annular adjusting member 31 as described in Specification 737,472. To maintain the annular members 16 and 30 in which the blades are pivoted in a given position relative to one another so as to prevent binding of the pivots, fixed blades 26 are provided. The fixed blades are attached to the flange 19 of the annular member 16 by studs 27 at least one of which is threaded to receive a nut 28 and to the outer annular member 30 by links 34 pivoted to spigots 33 on the blades and the member 30. The links 34 are disposed in a plane normal to the axis of the turbine or compressor, so that the blades 26 can expand and contract radially but' are not free to move axially relative to the casing 30. A shroud ring 30, which may be made up of separate arcuate portions, surrounds the fixed and adjustable blades and is mounted on and located by the spigots 32. The rear edge of this shroud ring abuts against a shoulder of the casing 30 to form a gas seal. To avoid all of the axial thrust on the blades 12 being taken through the outer ends of the blades, compressed air from the compressor is led through the shaft 15 and ports 22, 23 to the rear of the annular member 16. The blade platforms 35, Fig. 4, are provided with stops 36, 37 which in the end positions of the blades abut against corresponding stops 38, 39 on adjacent blade platforms.

Abstract: 647,498. Sorting &c. by weighing. HODGINS, R. D. SCOBLE-. Sept. 12, 1947. Nos. 25021 and 30422. Divided out of 647,486 [Class 143] Apparatus for sorting apples, fruit, eggs. certain vegetables and other suitable articles is of the type set forth in Specification 647,486, except that trays containing articles the weights of which are either in excess of a predetermined weight or lying between a plurality of weight ranges displace weighbridges which comprise electrical contact means for opening the trap gate or one of a number of trap gates adjacent the path, which are normally closed to prevent entry of a tray and which, upon opening, admit a tray which deposits the article contained therein into a compartment associated with the open gate. The feeding and conveying means and the trays are as described in Specification 647,486. The platforms 50, however, of the weighbridges, Fig. 16, are each connected through a link 73 to a quadrant arm 74, loaded with a weight 75, which is supported by pivot 76. The weight of a loaded tray causes arm 74 to move across stationary electric contacts 77, 78 and 79. According to the weight of the article in the tray the arm will come to rest on a contact 77, 78 or 79. Finger 22 of the tray now passes to another platform closing a switch 80 before passing on to track 23. This allows current from a battery to operate a solenoid 83, 84 or 85 respectively. The solenoid opens a trap gate 86, 87 or 88 the movement of which closes a holding-in contact 89, 90 or 91 so that the trap gate remains open as tray finger 22 passes from switch 80 along track 23 and into the open gate. As finger 22 enters the open gate it strikes the lower gate limb to close the gate behind it. In the case of arm 74 coming to rest midway between two contacts, however, two contacts are bridged and the two corresponding trap gates open. Finger 22 enters the first gate leaving the other open. A normally closed switch 82 placed before platform 50 is provided so that a succeeding tray finger first opens this switch which cuts off the current to all the gates. Alternatively a coupling device, Fig. 17, is provided, such as links 97, 97<SP>1</SP>, &c. pivoted to each trap gate and joined by links 98 so that finger 22 engages the link 97 which in turn engages the lower limb 103 of the first gate and also through link 98 causes the link 97<SP>1</SP> to engage lower limb 102 of the second gate so that both are closed. Various modifications of the weighbridge, contact means 1 and the trap gates are described, e.g. track 23 may be vertical, and the weighbridge may comprise a plurality of weighted rods adapted to be lifted in turn in the manner described in Specification 647,486, and the traps may comprise a sliding instead of a pivotally mounted gate. Specification 333,938, [Class 143], also is referred to.
