A marine-propeller assembly comprises a hub 19 that is rendered hollow and integral with a plurality of blades 21, a portion of said being cylindrical and supported by a bearing bush 13 lodged within a cylindrical opening 11 in the stern 10 of a ship. The end of the hub remoted from the blades is furnished with a flange that is coupled to shafting 36 by a plurality of bolts 41. The bush 13 is constituted by a plurality of axially-orientated rubber segments or staves 12, which are retained in the opening 11 by a ring 16 and a seal assembly 14. A slot (35), Fig. 3 (not shown), may be formed between two of the blades 21 to facilitate insertion of the staves 12 into the opening 11. In a second embodiment, Fig. 4, the blades 51 are removable from a hollow cylindrical hub 52 that is lodged in a bearing bush 53 and coupled to shafting 36 by studs 57, said bush being similar to the bush 13 aforesaid.

Abstract: 1,206,667. Production of packages; portable containers. SIDAPLEX S.A. 16 April, 1969 [15 May, 1968], No. 22966/68. Headings B8C and B8D. In a process for the production of a package, e.g. a container 4 for milk and which can be used as a disposable cup, a sheet 6 of biaxially orientated thermoplastic resin such as polystyrene, is heat sealed to the rim of the open container so as to form a lid and a knife 9, extending along an inner edge of the seal, is simultaneously pressed into the heat-softened sheet to a depth less than the thickness of the sheet so that a line of weakness 13, resulting from the pressure of the knife 9 on the inner edge of the seal, facilitates opening of the package when required. A succession of open containers (4), Fig. 1 (not shown), are passed from right to left, between heatable and unheated upper and lower jaws 1, 2 respectively of a heat sealing press, the jaws 1, 2, conforming generally to the rim 3 of a container, being arranged for relative vertical movement so that, when they are brought together, a sheet of biaxially orientated resin 6 is heat sealed to the container rim forming a lid and the knife 9 penetrates, e.g. to one-third of the thickness of the sheet 6, to produce the line of weakness 13. An outer knife 8 on the upper jaw 1 cuts through the sheet 6 so that the unused portion 11 of the sheet 6 can be torn away as it bends upwards over the roller 12. The sheet 6, made, e.g., of polyacrylates, polymethacrylates, polycarbonates; P.V.C.; polyethylene terephthalate; isotactic polypropylene and styrene copolymers, can have a thickness between 0À01 and 0À5 mm., e.g. 0À05 mm., the seal preferably being made as narrow as possible consistent with the production of an effective seal. The depth of the weakness is preferably between one quarter and two-thirds the sheet thickness, also a gap may be provided in the knife so that, after the weakness has been broken the lid remains hinged to the container rim.

[Also in Group XXVI] A method of deflecting the jet of a jet propulsion unit comprises locally increasing the temperature of an eccentered portion of the gas stream to establish a transverse temperature gradient in the stream so that distortion of the stream is produced with consequent engagement of the stream with laterally extending jet guiding means. The outlet casing 1 of a turbojet unit is connected to a reheat combustion chamber 3 and a nozzle 4, the latter being fitted with movable shutters 5 to vary the area of the nozzle outlet and an annular shield 6, of which a part 6a forms an injector orifice sucking in ambient air. A series of annular deflecting vanes 7 are secured to the nozzle. Two diametrically opposed sets of burners 8, 9 (one only of each set is shown) are fed from manifolds 10, 11 supplied through valves 12, 13. To effect deflection of the jet, one set of burners only is used, or one set is supplied with more fuel than the other. Flame stabilizing rings 14 are fitted to the exhaust core 2 of the turbo jet unit. Alternatively, the jet stream may be heated asymmetrically by heating a part of the wall of the duct by an external source of heat.

Trifluorovinylsulphonyl fluoride and tetrafluoroethylene are polymerized in perfluorodimethylcyclobutane under N 2 F 2  at 75 C. and 900 p.s.i.g. The copolymer obtained is reacted with methanolic NaOH containing a little H 2 0 and Et 3 N to give the sodium salt of the copolymer containing sulphonic acid groups. The free acid is obtained by treating the sodium salt with methanolic HCI. Perfluoro-[2-(2-fluorosulphonylethoxy)-propyl vinyl ether] and tetrafluoroethane can be similarly copolymerized and treated. Ion exchange films of the acids are obtained by moulding the initial copolymers and hydrolysing the sulphonyl fluoride groups. The films are useful in electric cells.

Title: Improvements in or relating to processes of agglomerating loose materials
IPC: C22B1/24
Filed: 1923-09-18
Abstract: 205,063. Stillman, A. L.. Oct. 3, 1922, [Convention date]. Processes. - A process of agglomerating or briquetting metalliferous loose material such as blast furnace flue dust or phosphate rock comprises mixing the material with an acid or metallic salt which will react with the material to produce a binder within the mass, subjecting the mass to pressure during the formation of the binder, and discharging the material from the press before the formation of the binder is completed, there being used in conjunction with the. acid or salt an agglutinant agent having of itself sufficient binding power to hold the mass together and preferably such as to render the compressed mass waterproof. In the case of blast furnace dust, which should be fresh so that it contains not less than about 10 per cent of ferrous oxide, the added substance may be an acid such as hydrochloric sulphuric, or carbolic, or a salt such as ferrous sulphate or magnesium chloride, the action being to convert ferrous oxide in the material into ferric oxide which acts as a binder or cement; in the case of phosphate rock the action is to form di-calcium phosphate which acts as the cement. The added agglutinant agent fulfils only the function of holding the briquette together during its fall from the press and subsequent handling and may comprise tar, pitch, asphaltic oils, neutral sulphite liquor, molasses &c. The two classes of addition may be made together in one substance. such as tar or pitch containing tarry acids, or acid sulphite liquor.

Abstract: 1427747 Logic circuits INTERNATIONAL BUSINESS MACHINES CORP 18 May 1973 [29 June 1972] 23713/73 Heading H3T A logic circuit comprises a plurality of switching circuits 1, 2 each arranged to pass a current along a respective current path to a common current node 19 upon satisfaction of a predetermined input signal condition i.e. the presence of two negative inputs at terminals 4, 5; 6, 7, a resistive load R and a latching circuit 22 actuated when at least one switching circuit is satisfied and arranged to cut off the passage of current to the node 19 from the switching circuits 1, 2 and to supply a predetermined current to the node. In operation, when positive inputs are present at either or both of input pairs 4, 5; 6, 7, the current from source I flows via transistors 12, 16 and through at least one of the pairs 8, 9; 13, 14 to line 17. However, when negative inputs appear at both terminals of at least one pair 4, 5; 6, 7 the current is diverted through the corresponding transistor 10, 15 to the common node 19 and a negative signal potential is produced at output 3. In the presence of a signal VS at the base of a latching transistor 22, this negative signal at output 3 fed back via a load transistor 23 to the bases of transistors 12, 16 is adequate to cut off current to switching circuits 1, 2 via transistors 12, 16 and re-route the current to the node 19 via transistor 22 until a reset potential is applied to the base of a further transistor 26. In an alternative embodiment employing a large number of switching circuits (Fig. 2, not shown) the feedback path for actuating the latching transistor is separated from the forward path to the output terminal.
