Patent ES-344168-A1 (ES)
Title: Sensor-actuated strand clamping and strand return mechanism for spinning apparatus
IPC: D01H4/08
Filed: 1967-08-16
Abstract: In open end spinning devices a thread clamp 7 is arranged between the spinning chamber or thread producing region (below lid 11) and the thread draw-off device 3 so that on stopping spinning or on decrease of thread tension the yarn is clamped e.g. in the outlet tube 6' to prevent the end leaving the chamber. The clamping arrangement is applicable to all forms of open end spinning devices e.g. rotary chamber type, Fig. 1, not shown, electrostatic type Fig. 6 not shown, stationary chamber type Fig. 7 not shown and pneumatic type Fig. 8 not shown. When restarting spinning the yarn end may be fed back into the spinning area by reversing rollers 3 or a normally extended yarn path F may be shortened to F' by movement of a guide 30 to provide an excess length. A pressure sensitive device in the spinning chamber may actuate the clamping device when spinning stops. In Fig. 5 the normal yarn tension in tube 6' holds a pivoted feeler 720 in a position such that an associated flag 722 blocks a light beam to a photo-cell. When the yarn tension drops the feeler and flag move to the position shown in dotted lines and the photo-cell is activated as a result compressed air is fed to clamp 7 and the thread clamped. When normal thread tension is re-established the photo-cell is again blocked and the thread is unclamped. In Fig. 9 not shown the thread clamping member (741) and the thread path extending member (31) are mounted on arms on a common shaft (32) rotatable by solenoid means under the control of the yarn tension feeler device. Thus the unclamping of the yarn and the yarn feed back are co-ordinated when starting up. The thread clamping device can be actuated pneumatically, electromagnetically, by hand or by a cam, for all spinning positions or at individual spinning positions. The clamp may be a flexible sleeve through which the yarn passes and which is surrounded by pneumatic means which compress the pipe and cause the yarn to be clamped. The clamping may be operated in response to yarn absence in the yarn outlet tube, the absence being sensed by a photo-electric device. A clamp may be provided which acts lightly on the yarn during spinning and is only released for reconnection or return feed. Reference has been directed by the Comptroller to Specificatior 1,092,596.

Title: Optical scanning device for rapid spectroscopy
IPC: G01J3/06
Filed: 1967-11-20
Abstract: In a device for scanning a spectrum photoelectrically the dispersed beam is reflected by a rotating mirror on to a series of fixed mirrors successively whence it is reflected through a number of slits to a small number of detectors. In a first embodiment, Fig.1 the dispersed beam R 1 from a prism 1 is reduced in size by a Cassegrain telescope 2, 3 and falls on a twosided rotating mirror m. The beam is reflected by mirror m in turn twice per cycle on to parabolic mirrors M 1 , M 2 , M 3 and M 4 whence it is reflected through slits G 1 , G 2 and via elliptical mirrors N 1 , N 2 to doped germanium detectors, D 1 D 2 . The output of detectors D 1 , D 2 may be displayed on a common oscillograph. In a modification, the mirrors may be elliptical with foci at mirror m and slits G 1 G 2 . In this case the telescope focuses the dispersed beam on the centre of the mirror m. In a second embodiment, Fig.2, the mirror m reflects the dispersed beam R 2 on to parabolic mirrors M 1 -M 8 and thence through slits G 1 -G 8 and via elliptical mirrors N 1 and N 2 to detectors D 1 D 2 . The invention may be used for the analysis of transitory chemical species in rapid reactions by infrared spectrography.

Title: Improvements in or relating to harvesting machines
IPC: A01F12/46
Filed: 1968-02-02
Abstract: A harvest-threasher utilises the same conveyer means for filling and discharging the hopper and includes a horizontal screw conveyer 5 at the bottom of the machine, co-acting with a vertical screw elevator 8, which connects with either a distribution duct 13 or a horizontal screw conveyer 10, both of which are rigidly attached to a swivelling turret 9. Cylinder 15 with aperture 17 rotatably mounted inside the turret connects either the distribution duct 13 or the screw conveyer 10 to the vertical screw elevator 8. Movement of the cylinder 15 is controlled by cylinder and piston unit 18. In operation the harvested grain enters the conveyer screw 5 from the bottom of the machine and is fed up the elevator 8 and projected by the radial blades 14 into the distribution duct 13 and hence into the hopper 4 and grain bins 2, 3. Even distribution of the grain is achieved by pivoting the turret 9 from a position in which the duct 13 extends at right angles to the longitudinal line of the machine to a position where the duct 13 is parallel to it. From the latter position, by opening the trap valves 6, 7 and altering the position of cylinder 15, the grain may be discharged through screw conveyer 10.

Title: Razor blade coating method and apparatus
IPC: B26B21/54
Filed: 1968-11-26
Abstract: The sharpened edge of a length of razor blade Strip is coated by forming the strip into a coil such that only the sharpened edge is exposed at the face of the coil, rotating the coil about its axis, and spraying coating material on the sharpened edge by moving the spray along a path parallel to said face. A holder 58, carrying a flat coil 128 of razor blade strip with its sharpened edge disposed outwardly in a vertical plane, is rigid with a horizontal shaft 290 journalled in a carrier 280 slidably mounted on horizontal bars 218, 220 for movement, imparted thereto by drive means 228, into and out of a spray booth 212. When carrier 280 is in operative position within the latter, a gear 292, rigid with shaft 290, meshes with a gear 300 rigid with a shaft 301 journalled in a structure 302 pivoted on a shaft 314, gear 3C0 being in constant mesh with a gear 312 rigid with shaft 314. A pulley 316 on the latter is driven by a belt 318 for rotating holder 58 when carrier 280 is in the operative position. Lugs 310 on structure 302 are biased against collars 286 on carrier 280 by a spring 306. A spray gun 132, directed downwardly by 5 degrees, is mounted on a bracket 266 rigid with a carrier 268 slidable on a vertical bar 270 and in screwthreaded engagement with a screwed-shaft 272, rotation of which serves to move gun 132 along a vertical path intersecting the axis of rotation of carrier 58. A supply tank (250) for spray material is moved synchronously with carrier 268. The speed of rotation of shafts 272 and 314 is varied by control means to maintain a substantially constant relationship between the angular velocity of the portion of the coil currently being coated and the effective transverse speed of the gun 132.

Title: Process for treating bodies made of glass or of vitrocrystalline or ceramic material
IPC: C03C15/00
Filed: 1969-09-10
Abstract: A body of glass, vitrocrystalline material or ceramic is chemically tempered as by ion exchange to provide a surface under compressive stress, after which a surface stratum of the body, preferably 0À1-20 microns thick, is chemically removed. The stratum may be removed by use of a fluorine-containing medium, preferably of pH below 4, so that the optical properties are not impaired. The medium may be HF, possibly with H 2 SO 4 (e.g. a solution containing 6% by vol. of each), NH 4 HF 2 , or NaF+H 2 SO 4 . Alternatively, a hydroxyl-containing medium, e.g. NaOH solution, may be used. The treatment is preferably performed with the medium at 0-80 C. The body may be dipped in a liquid medium, or streams of the medium as gas or liquid may be led over the surface. Preferably the body is vibrated relative to the medium at sonic or ultra-sonic frequency. After removal of the surface stratum the glass may be treated with water or a basic medium (e.g. by placing in a humid atmosphere, or by immersing in, e.g. 20% NaOH solution at 30 C. Preferably the process is continuous, with the surface stratum being removed substantially immediately after the chemical tempering. The body may then be coated, as specified in co-pending Application 32148/69. The body, which may be a glass sheet, may itself form a coating on a substrate. Specification 1,274,732 is also referred to.
