Title: Improvements in or relating to crimping of filaments
IPC: D02G1/00
Filed: 1960-07-21
Abstract: 909,361. Crimping fibres. HEBERLEIN & CO. A.G. July 21, 1960 [July 31, 1959], No. 25499/60. Class 120 (3). In a process for crimping continuous filaments (including filament bundles and filaments of rectangular cross-section) of thermoplastic synthetic material e.g. polyamide, polyester, vinyl polymers or copolymers, by converting the filaments partially into the plastic state lengthwise under tension on a surface portion of narrow width and subsequently relaxing the tension, a temperature gradient is produced within the filament (whilst it is under tensile stress) perpendicular to the longitudinal axis thereof with the aid of energy obtained from a fluid medium e.g. the hot gases of a (oxy-acetylene) flame, atomic hydrogen, a plasma jet, a stream of hot gas such as hydrogen or helium as may be contained in a closed cycle, or a liquid. The gradient may be produced in a filament which has not been subjected to any, or only partial, cold-stretching for the purpose of molecular orientation, and the cold-stretching completed after the processing. The crimp may be fully developed by an additional heat treatment e.g. with hot air, steam or hot water, of the filaments in relaxed condition.

Title: Gyrocompass or directional gyro
IPC: G01C19/38
Filed: 1969-05-20
Abstract: 1,207,660. Gyroscopic apparatus. SPERRY RAND CORP. May 20, 1969 [June 7, 1968j, No. 25561/69. Heading G1C. A gyro-compass of the type having a fixed parameter mechanical ballistic, e.g. a liquid ballistic 35, 36, 37 to render a gyro-rotor 1 meridian seeking, the compass being thus subject to horizontal and vertical rates produced by northerly speed and ballistic deflection, and a servo-loop comprising a pick-off 17, amplifier 25 and motor 22 with gearing 23, 24 for slaving a reference gimbal member 7 to the orientation of the rotor spin axis, also comprises a resolver 60 giving an output proportional to heading which is coupled to a transformer 66 through a potentiometer 65 the slider of which is driven by a source of speed data e.g. a ship's log 62 or manually set knob 63 so that the output of the transformer 66 is proportional to northerly speed, this signal being fed firstly to a torquer 45 which applies a torque to the gyro in a sense to oppose the vertical rate and cause the rotor to settle at a ballistic deflection Ï corresponding to the northerly speed, the signal also being fed secondly to the servo-loop for the gimbal 7 to bias the gimbal 7 through an angle corresponding to the ballistic deflection whereby the compass card 27 gives a reading of the true meridian course. In this way the necessity for the gyro to resettle after changes in speed and/or course is eliminated. The theory behind the applied electrical connection signals is given in the Specification and also automatic correction for acceleration errors. The compass card 27 is driven in a reverse direction to the gimbal 7 to present a natural indication to a person standing behind the compass in relation to the direction of travel as is usual, and a transmitter 30 is also provided for connection to repeaters if desired. The compass may be operated as a directional gyro by operation of ganged switches 80, 81, 82 which respectively operate a cut of valve 83 in the compass liquid ballistic connection tube 37, apply a voltage to the torquer 45 proportional to the sine of the latitude as set by knob 53 to maintain proper earth rate correction to the gyro, and cut off the biasing signal to the gimbal ring 7 servo-loop.

Title: Automatic mechanism for phonographs
IPC: G11B17/02
Filed: 1944-12-22
Abstract: 610,810. Magazine gramophones. INDUSTRIAKTIEBOLAGET LUXOR. Dec. 22, 1944, No. 25764. Convention date, Dec. 14, 1943. [Class 40 (ii)] In a magazine gramophone of the centre-post type in which records are steadied on the post by an overhanging arm having depending feet engaging the record, the automatic mechanism is arranged to be rendered inoperative when the record-steadying arm is swung away from the stacked-records to permit removal of records from the post, the machine then being in condition for non-automatic or hand operation. In the example described, the record-steadying arm 4, Fig. 2, is rotatably mounted on a pillar 3. The depending feet 33, 35, in the form of rubber rollers, for engaging the uppermost record of the stack are carried by linked pivoted arms 5, 6. Carried on the pivot 28 of arm 6 is a plate 29 which engages in a slot in the pillar 3 to lock arm 4 against movement when feet 33, 35 rest on the stack. The end of plate 29 is cut away so that when arms 5, 6 are lifted to raise feet 33, 35 off the stack, the plate is withdrawn from the slot and the arm can be turned to enable records to be lifted off the stack or placed thereon. The cut-away portion of plate 29 then engages the top of pillar 3 and maintains arms 5, 6 in raised position. When arm 4 is turned a pin 270, carried on a part rigid with the arm, engages an arm 269 carried by a shaft 187 extending eccentrically up pillar 3. This turns a bush 272 on the shaft and a pin 274 on the bush engages an arcuate portion 275 of arm 276, Fig. 3, which is secured to a member 99 which is rigid with an arm 96 having a further arm 92, the end 101 of which engages the clutch for the automatic mechanism and prevents operation of the clutch. Pin 274 obstructs movement of arm 276, while arm 4 is swung clear of the stack and prevents movement of arm 92 to a position clear of the clutch device so that the latter is maintained disengaged with the machine available for hand operation. The clutch device is fully described in Specification 610,809.

Title: Improvements relating to apparatus for the measurement of radiation and particularlyto radiation pyrometers
IPC: G01J5/60
Filed: 1950-10-23
Abstract: 705,264. Radiation detectors. PEDDING- HAUS, W., and PEDDINGHAUS, P. C. Oct. 23, 1950 [Oct. 27, 1949], No. 25776/50. Class 40 (3) A comparison device for enabling radiant energy travelling in two or more separate paths to be compared comprises modulating devices to chop or modulate the radiations at different frequencies or with different phase relations, a common receiver converting the energy received into electrical energy, a common amplifier feeding circuits separating the signals corresponding to the different input paths before applying them to an indicator or control device the separating circuits are fed with auxiliary signals from a generator or generators coupled with the modulating device in order that the separation may be effected. One of the radiations may be from a standard or comparison source. Two radiations may be directed to the receiver from different directions or originate at the same source and pass through different absorption substances and/or filters. The latter case may be applied to furnace temperature measurement, Figs. 3 and 4 (not shown). Various methods of indication may be used in any particular case for example the signals proportional to two radiation intensities may be separated and fed to a ratiometer, Fig. 5 (not shown). Other methods may comprise using one separated signal to control the amplification factor of the amplifier, the other signal being applied to an indicator, Fig. 6 (not shown); using the difference between the signals to control the intensity of one of the sources and measuring the control signal, Fig. 7 (not shown) ; or the difference between the signals may be applied to alter the transmission factor of a diaphragm, filter, wedge, or other obscuring or deflecting arrangement, the arrangement carrying an indicator, Fig. 8 (not shown). A number of ways o, modulating the radiations are suggested in the Specification. In one system a perforated disc is rotated having one or a number of rings of holes modulating the radiation beams at the same or different frequencies. A rotating disc system in which the radiation beams S1 and S2 are alternately applied to the receiver Z with a phase difference of say 70 degrees and the amplifier output signals separated by two phase bridges T1 and T2 in parallel from the amplifier output and supplied respectively with signals displaced in phase by 90 degrees to the two outputs is shown in Fig. 10. The two phase bridges fed with auxiliary potentials from generators G1 and G2 are arranged so that the component displaced in phase by 90 degrees to its own auxiliary potential is not passed and the separated signals are used in one of the ways described above. A system using a disc with two series of holes modulating two beams with different frequencies is described with reference to Figs. 12, 13 and 14 (not shown).

Abstract: 465,876. Roofs ; metal plates. GUYON, Y. Sept. 18, 1935, Nos. 25903 and 25904. Convention dates, Sept. 22, 1934 and April 4, 1935. [Classes 20 (ii) and 20 (iv)] Structures such as aircraft hangars and sheds, having large surfaces subjected to loads approximately normal thereto, are constructed so that such surfaces are in the form of surfaces of double but opposite curvatures, i.e. so that, e.g. transverse sections are concave downwards, whereas longitudinal sections are concave upwards. The surface may be formed directly from a continuous sheet or from a number of interconnected sheets, or may be formed by attaching a covering to a network of interconnected girders. The surface may be built of plane quadrilateral plates secured to girders formed as a system C1, C2, Fig. 1, or the plates may be folded along a diagonal XX, Fig. 2, to form non-coplanar triangles T1, T2 whose edges are secured to the girder system L1, L2. A separate girder system may be rendered unnecessary by bending the edges of the plates to form girder sections 1a, Fig. 3, such as channels, which are secured together. The sections may be formed all on one face of the plate, so that one face of the resulting surface may be continuous, or two sections along opposite edges may be formed on each face of each plate, so that when the plates are joined, longitudinal girders are on one face and transverse girders are on the other face of the surface. Corrugated plates may be used instead of plane plates, the corrugated plates overlapping at their ends and being secured to a girder system. Instead of plane quadrilateral plates, plates with two or more curved edges and shaped to a curved surface may be used. In some cases plane or curved plates may be suspended at their ends on girders' and allowed to hang in a natural curve to take up the position in which they are secured in the structure. Some of the metal plates may be replaced by glass, fibre or canvas, or by thin concrete slabs, and diagonal stiffeners may then be placed in the quadrilaterals so filled. The roof of a shed may be formed by straight rafters 15a, 15b, Fig. 10, arranged as the ruled lines on a hyperboloid of revolution, a canvas covering being secured to the rafters. Compression members, referred to in the Specification as tympans may be fitted on the edges of the surface to take thrusts arising from the transmission to the framing of the loads applied to the structure. The Specification as open to inspection under Sect. 91 included further examples of particular surfaces and rafter or girder systems thereon, but these are not included in the Specification as accepted.
