Abstract: 1485430 Foam producing nozzle attachment CHEMTRUST INDUSTRIES CORP 23 Dec 1974 [14 Jan 1974] 55482/74 Headings B1C and B2F A foam-producing attachment 33b for a liquid-spray producing nozzle 33a, comprises a hollow cylindrical body 40 provided with air-inlet ports 43 immediately in front of a known spray-angle adjusting member 33c, secured into the body 40; a pressure-reducing passageway having a portion 46a tapering in the downstream direction and having a cylindrical turret portion 46b; and a foam thickness-enhancing cylindrical expansion chamber 41 having a diameter greater than that of the throat portion 46b, so that during use the liquid-spray issuing through a flared orifice 42 under pressure mixes with air entering through the ports 43 and foam is produced in the passageway. The spacing between outlet orifices 32 of the nozzle 33a and the orifice 42 is adjustable by rotating the attachment relative to the nozzle 33a so as to vary the cone angle of the spray and thereby vary consistency of the foam, the latter being maximum when the spray impinges on the walls of the tapered portion 46a. The cone angle of the tapered portion is at least 60. The length to diameter ratio of the expansion chamber 41 is preferably between 7 and 20 to obtain high consistency foam issuing with sufficient velocity to reach a surface to be cleaned; and the diameter of the expansion chamber 41 is at least twice, and preferably three times, the diameter of the throat portion 46b. Arrangements for supplying liquid containing soluble cleaning chemicals and a foaming agent to the nozzle 33a under pressure are disclosed.

Prior to covering the web 1, the arm 13 is arrested by a lug 25 abutting a stop 26 in piston of cylinder 27, whilst the other arm 5 encloses the core 3, Fig. 3, with its guide shell 6 and a roller 10 driven at higher speed than the speed of moving web 1 drives the core up to speed. Thereafter the cylinder 27 is actuated to release the arm 13 which under the bias of a spring 20 in a dash-pot 35 causes the knife blade 17 to be released resiliently with a sharp action to sever the web. The blade 17 and shell 6 from a guide for the leading edge of the web which is gripped subsequently by the roller 10 to tension the web and feed the leading edge past a guide member 11 into the nip formed by the core 3 and a further roller 16. Several coils are then allowed to be wound onto the core 3 with the arm 13 interlocked by pawl 23 (Fig. 4) and thereafter the arms 5, 13 are returned to the portion shown in Fig. 1. The resilient release of knife blade 17 and driving the core 3 in frictional contact with the roller 10, which in turn is driven via a frictional clutch, ensures core change without damaging the surface of the web which may be a photographic film.

Abstract: 1283289 Rotary positive displacement machine HYDRO-COMP Inc 14 Dec 1970 [15 Dec 1969] 59343/70 Heading F1F A fluid pump or motor 20 has a generator unit 30 comprising a stator ring 31 and a rotor 32 and reciprocating piston valves 60 to admit and exhaust respectively to and from expanding and contracting chambers 33 formed as the rotor orbits within the stator. The rotor 32 is between wear plates 50, 65 and is rotated with a shaft 40 and short shaft 45. Piston valves 60 are radially arranged in a valve cyclinder plate 61 and provide a fluid passage between input and output fluid bores 24a, 24b, Fig. 4, and the chambers 33 through input and exhaust apertures 61b, 61c in the plate 61 around a neck portion 60b of the pistons and through chamber apertures 61d to apertures 65a in the wear plate 65. Connection is made as appropriate to the input and exhaust apertures 61b, 61c by reciprocation of the piston 61 by an eccentric cam surface 70c of camming means 70 which is caused to orbit with the rotor 32 by an extension 45c of the shaft 45 engaging an actuating slot 70e. Thus three expanding chambers 33 are supplied with input fluid while three contracting chambers are connected to the exhaust bore 24b and one piston will be changing from exhaust pressure and will not pass fluid. It is possible to adjust the timing of the pistons by relative rotation of the cyclinder plate 61 and the wear plate 65 within the limits of permitting communication between apertures 61d and 65. In other embodiments the pistons 60 may be actuated by a stor cam rotated by the output shaft and the pistons 60 may be arranged parallel to the lonitudinal axis to be actuated by rotated radially disposed rollers or an undulated cam. It is stated that the arrangement may also be used in a metering device.

IPC: B63C7/28
Filed: 1969-12-06
Abstract: 1,273,600. Ships &c. KINGSTON MARINE TECHNOLOGY Ltd. 26 Oct., 1970 [6 Dec., 1969], No. 59675/69. Headings B7A, B7S and B7V. A method of beaching and refloating e.g. a landing craft involves the use of rams 15 at the beached end of the vessel. The rams hang freely from pivots 16 and can swing through equal arcs limited by stops, the more nearly vertical position of the rams being that shown in Fig. 1. To refloat when beached, the rams are extended thus raising the end of vessel clear of the beach. Since the bow is floating and the rams are angled, the ship moves forward under its own weight. To beach, further rams may be used to force the supporting rams to pivot to bring the vessel ashore, or the supporting rams may be arranged so that the vessel beaches under its own weight. The two propellers 12 are rotatable for steering and are retractable into a well 13 in the hull to avoid the beach propulsion being continued by hydraulic bow thrust unit 14. Alternatively non-retractable propellers may be provided beneath overhanging sponsors.
