Patent GB-909111-A (GB)
Title: Load supporting hanger
IPC: F16L3/20
Filed: 1959-06-05
Abstract: 909,111. Automatic force control. GRINNELL CORPORATION. June 5, 1959 [Aug. 20, 1958], No. 19258/59. Class 38 (4). In a system for supporting a load from a fixed structure with a constant force, the axes of a motor-driven jack controlling the force, a spring load-measuring device and a load supporting member are in one vertical straight line containing the point of suspension, and a pivoted lever, operating an electrical switch to control the motor automatically, is engaged by the spring load-measuring device at a point as close as constructionally possible to the vertical straight line. In Fig. 1 piping (not shown) is supported by rods 54, 59 from a nut 52 in threaded engagement with a rod 34 which rests on a compressible member 26 carried by a fixed support 10. Member 26, which is compressible by virtue of a piston 30 resting on disc springs 28, permits movement of the lower end of rod 34 with changes in load due, for example, to thermal effects on the piping. This movement is transmitted through a projection 48 to a lever 41, pivoted at 39 to the fixed support 10 and passing through a hole 35 in piston 30, to move a carriage 44 operating switches (not shown). If the load deviates beyond a predetermined extent in either sense one or other of two of the switches is operated to run an electric motor 51 in the appropriate direction to correct the deviation by rotating rod 34 and thereby raising or lowering nut 52. When the deviation is corrected one or other of two further switches is operated to stop the motor. Nut 52 is prevented from rotating by virtue of guides 62 on fixed support 10 and a thrust bearing 32 facilitates rotation of rod 34. In a modification, rod 34, which does not rotate, extends downwards to support the piping and is adjusted in position vertically by a nut rotated through worm gearing by motor 51, force being applied to lever 41 off the centre line of rod 34 in a blind hole in piston 30 which is, in this case, between the nut and the fixed support.
Patent GB-595257-A (GB)
Title: Improvements in and relating to the manufacture of products comprising fragmentary wood material bonded with synthetic resin
IPC: B27N7/00
Filed: 1944-10-07
Abstract: Panels and the like, resembling natural wood are obtained by a process which comprises treating fragmentary wood material with a solution or suspension of a bonding material containing at least a proportion of thermosetting synthetic resin, moulding the treated material to panel form, curing it with the application of heat and under a pressure which is insufficient to close the pores of the treated material and applying to the panel, after cooling and hard setting of the latter, a binding material which penetrates the surface, at least, of the panel so as to render these surfaces non-porous and which forms with the surface layers of the treated material a solid water insoluble coating which substantially increases the mechanical strength of these layers. The wood waste may be wood chips, shavings, or coarse sawdust; wood flour may be used in small quantities but should not predominate.  Graded portions from special sources such as walnut wood may be used in order to produce special burred effects. About 10 to 12 per cent. of synthetic resin which may be a phenol-aldehyde resin in alcoholic solution may be used and the mixture moulded at a temperature of about 150 DEG C. at a pressure of 500 to 2200 lbs. per square inch.  An accelerator may be added to enable curing to be effected at lower temperatures.  Wax may be added either in powder or flake form or in solution to the impregnated material, and it may be added to the thermosetting resin which is used for the initial bonding agent.  The final bonding agent may be a thermosetting or thermoplastic resin. Panels may be finished by buffing or grinding and then the surface treated with a lacquer, resin cement or wax.  Modified products are obtained by bonding sheets of veneer on the outside or by utilising as an inner layer, cork, wool or felt impregnated with resin, or by reinforcing with wire mesh.  The panels may be stained or coloured either during or after manufacture.  Curing may be effected by heating between platens, by hot air or by radio frequency currents.

Title: Improvements in or relating to drum-winding machines
IPC: B65H54/10
Filed: 1922-07-14
Abstract: 205,550. Wade, H., (Universal Winding Co.). July 14, 1922. Winding-machines; stop-motions. - In drum winding-machines, the angular relationship of the axes of the yarn spindle and friction drum is varied by guiding and controlling means combined with the friction drum and yarn spindle support and of such shape and disposition as to determine a desired variation in the angular relation of the axes and positively to preclude during winding any other relative movement of the drum and spindle. The guiding and controlling means consist of cam grooves 29, 30 formed in the face of a vertical plate 31 adapted to be engaged by rollers 25, 26 one carried by each of the projections 23, 24 of an arm 20 to which is secured an arm 9 having pivoted in a slot at its outer end a hinge member 8 on which is mounted the mandrel-carrying spindle. The arrangement of the guiding and controlling means is such that the yarn spindle is moved away from the friction drum D due to growth of the package, and' has a gradually increasing inclination relatively to the friction drum imparted to it by being moved in a path such as would be generated from a pivot progressively displaced longitudinally of the drum axis. A flat spring 38 fastened to the arm 20 bears against the rearward face of a cover plate 32 and causes the arm 20 to be maintained in contact with the guide 36 on the plate 31. In rocking the handle 62 to start the machine after the cone-holder and friction drum are in contact, an arm 47 is tilted into position to allow a pawl 46 to engage the teeth on a quadrant 44 which is formed integral with a hub 42 secured to the cone-holder support 21, this action being effected by a spring 55. As the yarn package grows, the quadrant 44 is carried upwards and the pawl 46 will ride over the teeth 45. The spring 55 also acts temporarily to support the bobbin through the medium of the pawl 46 immediately after jumping action of the bobbin due to faulty winding. The machine is stopped automatically upon yarn breakage or completion of package through means connected with the detent lever 67', which when released from the notched plate 70 causes the spring 65 to rock the arm 47 to raise the pawl 46 bodily and hence to lift the package away from the drive-roll D.

Title: Process of melt spinning tubular or bubble-containing filaments
IPC: D01D5/247
Filed: 1966-05-05
Abstract: 1,097,155. Melt spinning hollow filaments. E.I. DU PONT DE NEMOURS & CO. May 5, 1966 [May 5, 1965], No. 19949/66. Heading B5B. In melt spinning hollow filaments either of the tubular type or the bubble-filled type, the gas for filling the axial continuous cavity in the tubular type or for forming the bubbles in the bubble-filled type is provided by thermally decomposing a portion of the polymer flowing to the spinneret. The thermal decomposition may be effected by means of an electricallyheated high resistance wire and the proportion by volume of voids in the filament may be controlled by voltage regulation across the wire. If the filaments are to be of the tubular type, a centre-obstructed orifice spinneret is used and if the filaments are to be of the bubble-containing type, a conventional spinneret is used, but finely divided solid particles must be present in the polymer to serve as bubble-forming nuclei. The particles preferably consist of a mixture of one of the conventional pigments and a special nucleating agent such as sodium or potassium acetate. Pyrolysis of the polymer may be effected by heat applied externally to a portion of the polymer piping system. The filament material may be a polyester such as polyethylene terephthalate or a polyamide.

Abstract: 1365739 Photo-electric velocity determination HASLER A G 28 April 1972 [4 May 1971] 19964/72 Heading G1A In an arrangement for measuring the speed of a body using a pair of transducers 8, 9, Fig. 1 producing electrical signals based on a local characteristic of a parallel surface, and spaced by a predetermined amount in the direction of motion, the signals are sampled and multiplied one with the other in a unit 14 after the leading signal has passed through a delay element 12 the delay of which is adjusted by the ultimate output of a variable frequency pulse generator in a unit 16, to bring them into phase (waveform coincidence). A phase difference signal is selected by a low-pass filter 15 in the output circuit of the multiplier and synchronism is achieved by a delay adjusting signal developed in a maximum seeking controller unit 16 and applied over lead 13. The generator pulse frequency which constitutes the signal is measured by a frequency meter 17 to indicate velocity, and is also applied to a pair of switches 10, 11 to control the periodicity of sampling of the transducer output voltages, to the low pass filter in a system using coded discrete pulses to determine cut-off and to the multiplier. A suitable discrete filter and a maximum seeking controller are described with reference to Figs. 4 and 5 (not shown) and a modified embodiment in which the two transducer outputs are delayed to different extents and compared is described with reference to Fig. 6 (not shown). The surface from which the characteristics are read may be illuminated at the same pulse rate and the delay circuit may have additional steps for additional velocity ranges.
