Abstract: 131,736. Campbell, L. M. Aug. 29, 1918. Stability and trim, determining and indicating.-A frame ADE carries a pendulum suspended at A and has its lower bar GF pivoted at F<1> and provided with a vernier scale at G<1>. In order to determine the vertical position of the pendulum the bar GF is provided with a graduated scale and spirit level I, while the pendulum B car. ries a registering mark. The frame ADE is arranged to move freely between two side frames of which one, JKLM is shown, while an extension Q of these frames carries a scale S which is graduated to read feet of alteration in trim. The apparatus is adjusted so that when the ship is on an even keel, the reading on the scale S is zero. The bar GF is moved by means of the screw and nut T, U, and the whole frame ADE turns about the pivot F<1> until the pendulum is central. The reading on the scale S then gives the trim. The side frames JKLM are provided with knife-edge bearings J<1>, M<1>, resting on brackets V, W, carried by a beam X which is pivoted at Y. The beam X may te clamped in any position by a nut Z. The two side frames shown as O, P, Fig. 2, carry a graduated quadrant q<1>, and a pointer p<1> is fixed to a bracket on the beam X so that the list of the vessel is shown in degrees. The apparatus may be used in connexion with a sounding-pipe placed midway between the bow and stern, so that the draught at the bow and stern may be obtained from the draught amidships by adding or subtracting an amount determined from the trim as indicated on the scale S. The apparatus may be used in connexion with ships, floating cranes, floating docks, or the like.

Title: Improvements in the production of monofilaments
IPC: D06M13/52
Filed: 1942-10-15
Abstract: A unitary filament is made by fusing a bundle of filaments of a thermoplastic substance and before or after the coalescence of the filaments they are subjected to a superficial treatment with a swelling agent and to drying to remove the swelling agent, and p these treatments are followed by a polishing of the surface of the unitary filament by abrading.  The filament substance may be a polyvinyl compound such as a copolymer of vinyl acetate and vinyl chloride, polyvinyl chloride, or chlorinated polyvinyl chloride. The filaments may be stretched during their production and before they are coalesced to form the unitary filament.  Preferably, the bundle of filaments is twisted and then subjected to heating to coalesce the filaments while held so as to prevent longitudinal contraction. Heating may be performed by steam, hot air, hot water, or other heated fluid which is inert with respect to the filament substance, e.g. glycerine, ethylene glycol, or other polyhydric alcohol.  The monofilament may be polished by means of pumice powder in olive oil. The monofils may be used in making hosiery or other knitted or woven fabrics, such as nets for ladies' shoes, violin strings, racket strings, bristles for brushes, artificial horsehair and the like.
