Title: Improved means for launching boats
IPC: B63B23/04
Filed: 1928-11-30
Abstract: 323,880. Franklin, H. A., Partridge, R. J., and Roberts, E. A. Nov. 30, 1928. Boat-lowering gear comprises a davit displaceable transversely of the ship and angularly adjustable when outboard. A transverse gantry a supports the davit girder b which is extended over either side of the ship by rack and pinion gear. When outboard, a pinion h on the inboard end of the girder b engages with a fixed toothed quadrant g and controls the movement of the girder b into alignment with the gantry. The angular disposition of the girder b is controlled by tackles w which the davit picks up from pegs B during its outboard movement, the tackles passing over samson posts Y. Bridge members s, Fig. 8, span the gap between the inner end of the girder b and the outer end of the gantry a. The boatlowering tackle comprises ropes k paid out from bollards z as the girder b is displaced outwardly where they engage with end pulleys m on to which they are locked by the fall of a key M. The ropes k are provided at intervals with thimbles n, Fig. 4, which pick up hooks o on wheels q which run freely on rails on the underside of the girder b. Links N<1> connect the hooks o to boat-suspension hooks p carried by distance pieces P about equal to the width of a boat. When the pair of wheels supporting the boat reaches the end of the girder b and an inboard flap Q, the boat descends the rope k now passing over pulley V. The weight of the descending boat serves to transport outboard the next boat which has been picked up by an adjacent pair of thimbles n.

Abstract: 358,784. Coal-cutting machines. MOORE, M. S., 34, Rue de Bruxelles, Tervueren, Belgium. Nov. 27, 1930, No. 35704. Addition to 357,816, [Group XXX]. [Class 68 (i).] A machine for gathering coal &c. at the coal face and loading it into a conveyer in an adjacent runway of the kind described in the parent Specifica. tion is provided with a cutting appliance for undercutting the coal when the machine moves in one direction while the loader bar gathers up the broken coal as the machine moves in the other direction. The casing 3 carries a cutter chain 10, or bar, for undercutting the coal. A conveyer 2 is mounted on the casing by means of a turntable 43 so that it can be arranged in line with the casing or transversely of it. When the undercut has been completed, the conveyer is rotated into the cut and the broken down coal is removed by means of a toothed gathering bar 1a which feeds the coal over a toothed comb 7 on to the conveyer which discharges it into a conveyer 31 in the adjacent runway. A motor 4 drives the cutter through gearing 52, the conveyer 2 and gathering bar through a disconnectible coupling 62 and the haulage gear 5 through gearing 48. The cutter may have some of its teeth 70 replaced by scrapers 71, Fig. 7, for gathering loose coal on the non- cutting stroke. The teeth 6 of the gathering bar are arranged in a double helix.

Title: Dressed textile material and a process for its manufacture

Filed: 1970-07-23
Abstract: 1311495 Weighting textile material; padding mangles J GUINDI 23 July 1970 [23 July 1969] 35713/70 Headings D1L and DIP A process, for weighting textile material, comprising treating the textile material with a liquor which comprises a solution or melt of a monomer and treating the treated material with superheated steam in order to at least partially polymerise or polycbndence the monomer. The monomer, e.g. caprolactam should be readily converted to the liquid state, be water soluble and be used in aqueous solution. A mixture of monomers may be used, wherein the or each monomer is in admixture with a polymer, the latter preferably being in finely divided form. The solution or melt of the monomer also comprises one or more additives, e.g. delustring agents, dyestuffs. The temperature of the superheated steam is 130 to 180‹C so that the textile material is at a temperature above its softening point and the treatment time 15 to 120 seconds. When an oxygen-sensitive monomer is used, the process is carried out in an inert atmosphere. Textile materials suitable for treating are those comprising synthetic thermoplastic polymers, especially polycondensates based on polyamides. Other polymers which may be treated are for example polyesters, polyacrylonitrile polyethylene and polypropylene. Also textile materials comprising natural fibres, e.g. wool, silk and cotton, man-made fibres, e.g. rayon and mixtures of both may be treated by the process. Best results are obtained when the textile material and the polymer formed from the applied monomer(s) are chemically similar. Apparatus suitable for carrying out the process comprises a padding mangle 2 through which the material 1 may be run, a housing 4 for the padding mangle 2, which housing may be filled with an inert gas. The housing 4 is heated, the roof 5 of the housing 4 being serrated in cross-section and heating pipes 7 being disposed beneath the troughs of the serration 6. The material 1 is conducted to the impregnating trough 12 by guide rollers 10 and 11. The trough 12 is filled with the treating liquid and a disperser 14 is disposed above the roller 15. After the guide rollers 16, 17 and 18 the material passes between nip rollers 19 and 20. The material 1 is then conducted to a flexibly mounted tensioning roller 22 and then passes by way of guide rollers 23, 24 and 25 through a connecting funnel 28 into the steamer 3. The material 1 is then conducted to roller 33 provided with holes through which superheated steam is blown, by roller 32 and then over a battery of transport rollers 34 drawn by roller 33. The material 1 then passes over guide roller 36 and leaves the closed steamer through an exit 38 in or close to the floor of the steamer.

In a bath and wash basin unit combining a tub 2, a basin 4 and a water heater, the latter is in the hot water supply to a mixing valve 15 having a swivelling discharge pipe 16 to supply the basin 4 and tub 2, being installed in a casing 1 covering it and the tub 2. The pipe 16 carries an outlet tube 18, a shower head 19 and a rotary valve member 17 for alternatively connecting the water from the valve 15 through the pipe 16 to the tube 18 and the shower head 19. The water heater may be an electric flow heater 12, Fig. 1, or a flow heater consisting of an elongated rod-shaped radiator 34, Fig. 4, surrounded by water tubes 37 of a tube which may be coiled around the radiator 34, either of which may be in a horizontally extending compartment 35 whereby the tub 2 is also heated when it is partly enclosed by insulation 36 in the casing 1 below the tub 2.
