Title: Boats equipped with means for removing oil from their bilge water prior to discharge
IPC: B63B13/00
Filed: 1975-02-05
Abstract: 1489464 Bilge filter V S PEDONE 5 Feb 1975 [26 July 1974] 4985/75 Heading BID [Also in Divisions B7 and F2] The bilge water from the engine room of a boat is pumped back to the surrounding water via a filter for removal of oil and comprising a housing having an inlet and an outlet and containing in series in the flow path between them, (a) fluid distribution means, (b) a first mass of particles of expanded, open-pore oleophilic and hydrophobic synthetic resin, e.g. polyurethane, (c) a second mass of such particles of a size less than that of the first mass, and (d) porous means having through passages of a size to prevent passage of the particles of the second mass. The filter may comprise alternating layers of the two masses and be designed so that it is symmetrical for use in either direction. Figure 2 shows such a filter having a moulded plastics or metal casing 19 with inlets/outlets 13, 14; foam resin sheets 21 forming the porous means; perforated baffle plates 22 forming the fluid distribution means; and alternating layers 23, 24 of the first and second masses, respectively. The filter element may be used with or without a surrounding housing. The particle size range of the first mass may be 2000-5000 microns and that of the second mass 2000 microns and below. The particles may be formed by cutting foam material to produce open-cells. The downstream side of the filter may be connected to an indicator to show when oil passes the filter upon saturation of the foam material. The indicator is suitably arranged to be visible from the outside of the boat and may comprise a transparent casing containing a material, white cotton fabric, discoloured by oil contact. A pressure relief valve may be inserted between the filter and the bilge pump to vent the pump during shut-down and start-up and a by-pass may be provided to enable discharge of bilge water without passage through the filter.

Title: Improvements in the preparation of photographic emulsions
IPC: G03C1/015
Filed: 1949-02-25
Abstract: 676,745. Photographic emulsions. KODAK, Ltd. (Eastman Kodak Co., and Damschroder, R. E.). May 25, 1950 [Feb. 25, 1949], No. 5247/49. Class 98 (ii). A photographic silver halide emulsion is prepared by a method including the step of reacting a silver compound with an ammonium halide or an alkyl-ammonium halide to form silver halide, the reactants being such that the products of the reaction, other than the silver halide, are substantially volatile, and removing at least part of the volatile products from the reaction mixture by vaporization. The reaction may be performed in the presence of a peptising lyophilic colloid, e.g. gelatin, polyacrylamide or imidized polyacryamide resin as described in Specification 646,712, or oxidized protein (e.g. casein) derivatives as described in Specification 648,927. The silver compound may be the oxide or carbonate and may be used in aqueous ammoniacal solution. The silver oxide may be dissolved in aqueous ammonia in presence of gelatin, and fog may be prevented by adding potassium permanganate. The ammonium compound may be the chloride, bromide, or iodide, and the alkyl-ammonium halide may be methyl or ethyl ammonium bromide or chloride or a dimethyl or trimethyl ammonium halide. The volatile products may be removed by vacuum distillation before or after ripening or digestion, but ammonia is preferably removed before ripening. With alkyl-ammonium halides, washing of the emulsion with or without previous vacuum treatment may be necessary. All or part of the ammonia may be removed. The silver halide reaction mixture may be continuously fed from the reaction chamber to the evacuation chamber. In example 1, sodium hydroxide solution is added to silver nitrate solution to precipitate silver oxide, which is then separated, washed, and dissolved in excess aqueous ammonia. The resultant solution is run into an aqueous solution of ammonium bromide and iodide and gelatin, and the reaction mixture is passed through an evacuated chamber as a thin film of liquid. Gelatin, or other protein, or hydrolysed cellulose ester, or polyvinyl alcohol is added, and the emulsion ripened or digested in the usual manner. In example 2, the procedure is similar, gelatin being added to the final emulsion, the pH adjusted with dilute sulphuric acid, and dilute silver nitrate added. In example 3, the ammonia is replaced by aqueous methylamine, and in example 4, the ammonium bromide is replaced by trimethylammonium bromide. In example 5, the procedure is similar, using silver carbonate. In example 6, the gelatin of example 2 is replaced by the acrylonitrile-acetyl derivative of oxidized casein.

Abstract: 740,009. Calculating-apparatus. OLYMPIA WERKE WEST GES. Feb. 25,1953 [Feb. 29, 1952], No. 5286/53. Class 106 (1). A calculating-machine has a reciprocating paper carriage and is characterized in that the reciprocating movement is imparted to the paper carriage by a double-faced cam which is keyed on a shaft extending parallel to the direction of the carriage movement. The base-plate 20, Figs. 1 and 2, of the paper carriage has a series of holes 21 any selected consecutive five of which are engaged by the teeth 14 of an index member 13 carried by a U-shaped member 12. A pin 11 is selectively mounted in one of three pairs of holes 12a of the member 12 and is embraced by the upper forked end of a lever 9 pivoted on a bearing 8 and carrying intermediate its ends two rollers 10 which follow the cam surfaces of a double-faced cam 3 carried by a shaft 2 connected by a clutch to a shaft 6 rotated through a chain and sprocket drive from the shaft 22. Each machine cycle the cam 3 effects reciprocation of the paper carriage through the lever 9, pin 11 and member 12. A projection 15 carried by the member 13 co-operates with fixed stops 16. To reset the carriage with respect to the member 12 the member 13 is moved downwardly by depression of a key (not shown) to disengage the teeth 14 from the plate 20, the carriage is then moved to its new position and the member 13 is released to re-engage the plate 20. The position of the pin 11 determines the length of stroke of the carriage. Hand-operated means may be provided for effecting disengagement of the clutch between the shafts 2 and 6.

An electric radiator or air heater for rooms is of large superficial area in relation to its thickness and comprises two metal sheets 1, 2 formed with serpentine channels 3 enclosing an electric heater when the sheets are superposed, the outer face of one sheet being bright and of the other sheet dull. The radiator is mounted in a metal casing 19 open at its front through a grill 11 and and open at its bottom. Partitions 12, 14 are mounted across the width of the casing behind the heater and are bent forward at the top to direct air through the grill 11. The heater comprises a helical resistance wire 5 sheathed by insulating sleeves or beads. The dull face of the sheet is produced by black paint or spraying or brushing colloidal graphite in acetone on the sheet and shot blasting or roughening the coated surface to increase the radiating area. The serpentine channel is formed in one or both sheets and comprises straight vertical runs joined at the ends by semicircular grooves, the sheets being screwed or riveted together. Louvres 8 may be pressed out of the metal sheets between the vertical grooves. Clothes may be dried on the casing 19, the top of which is open or closed. One or more lamps. 21 illuminate the front of the heater and indicate whether the current supply is switched on. An adjustable thermostat 20 is mounted in a side of the casing and acts as a safety device if the casing falls forward, so as to trap hot air in the casing. A water trough with wicks may be provided at the top or bottom of the casing.

Abstract: 1443172 Composite pipe MONMORE TUBES Ltd 6 May 1974 [9 Feb 1973] 6368/73 Heading F2P [Also in Division F1] A composite pipe comprises a mild steel tube clad on its inner surface with stainless steel and coated on its outer surface with a corrosion resistant metal such as zinc. Said pipe can be made from a length of mild steel strip clad on one of its surfaces with an adherent lamina of stainless steel. The strip is bent to form the pipe shape and butt welded at its longitudinal edges. The exterior surface of the pipe so formed is then coated with a corrosion resistant metal such as zinc. The stainless steel lamina may have a thickness in the range 8 to 20% of the thickness of the mild steel strip and the corrosion resistant coating a thickness in the range 1 to 3% of the thickness of the mild steel strip. The pipe is particularly suitable for use in exhaust pipe systems, e.g. between an exhaust manifold and a silencer and for a tail pipe from the silencer. In such a system the silencer may be similarly constructed.
