Title: Improvements in and relating to cruising plant for warships having steam turbine drive
IPC: B63H23/00
Filed: 1920-06-22
Abstract: 169,275. Schmidt, W. June 22, 1920. Driving-arrangements for screw propellers. - Relates to cruising-plant for warships, and consists in using an internal-combustion engine and steam-engine wherein at low speeds the steam for the engine is obtained from the exhaust and water-cooling systems of the reciprocating engine, which steam is progressively supplemented by boiler steam as the speed is increased. For full speed, main turbines are employed, and the cruising-plant is closed down. The cylinder jackets are connected to a common collecting drum from which the steam is drawn for the engine. The plant comprises a propeller shaft H on which is freely mounted a pinion J with claw coupling K, Figs. 2 and 3, the pinion J being driven by an internal-combustion engine A through a wheel L and by a turbine B through a wheel M. A feed-pump F draws from a feedwater tank E, which is supplied from the condenser C and delivers the feed-water to a coil b in the exhaust-gasheater G, from which the water goes by the pipe c to the drum N by the pipe c<1> or by the pipe c<2> to a boiler. From the vessel N the water passes to the bottom of the waterjackets d<1> - - d<6> up through the jackets, thence by steam-pipes e, e<1> - - e<6> to the top of the drum N. The steam-pipe f from the drum and steampipe g from the boiler are coupled to superheating- coils k in the exhaust-gasheater G, from which the steam-pipe m goes to the turbine B. The disposition of the plant in a ship may be varied; in one arrangement the main turbines T and condensers S, Fig. 4, are arranged in a forward compartment, and the cruising plant is placed aft. In cruising, one shaft is driven by the internalcombustion engine A and the other by a reciprocating steam-engine B, which utilizes the waste heat of the engine A, G being the waste heat unit and C the condenser. Clutches U are provided for cutting out the main plant when cruising.

Title: Improvements relating to soldering fluxes
IPC: B23K35/36
Filed: 1936-06-19
Abstract: A hollow solder member is filled with a solid or plastic core comprising a resinous material such as colophony or shellac having incorporated therein an inorganic fluxing material such as zinc chloride or ammonium chloride, the proportion of the inorganic material not exceeding 5 per cent by weight of the core.  The inorganic material is present in true or colloidal solution or in a finely divided state.  A plasticizer, e.g. turpentine, may be introduced to adjust the consistency of the core.  Corrosion of the work after soldering by reason of residual inorganic flux is prevented by the film of resinous material which solidifies thereon and which may be rendered inconspicuous by colouring it. Examples of core compositions are (a) 1 part of ammonium chloride milled with alcohol and added to 100 parts of molten colophony, (b) 1 part of zinc chloride heated with 200 parts of colophony until a clear molten solution is obtained.  The first Provisional Specification refers to the use of gums and waxes as well as resins in preparing the core. Specifications 323,392, [Class 82 (ii)], and 368,841 are referred to.

IPC: A24C5/32
Filed: 1966-12-23
Abstract: 1,209,898. Pneumatic conveyers. MOLINS MACHINE CO. Ltd. 21 Dec., 1967 [23 Dec., 1966; 28 Feb., 1967; 14 April, 1967], Nos. 57611/66, 9503/67 and 17364/67. Heading B8A. Figs. 2, 3 show apparatus for feeding rod-like articles such as plugs P of cigarette filter material comprising a hopper 3 serving a bank of plug guns 1, Fig. 1 (not shown), each plug gun 1 being fed with a single stack of plugs P by vertical extensions 59 of guides 14. A delivery rotor 9 and a discharge rotor 10 are mounted in bearings 11, 12 in gun block 2 for continuous rotation together about a common axis. The delivery rotor 9 receives the plugs P in eight flutes 13 each of which is successively moved past an air jet 16 whereupon the plug P therein is blown along the flute to the discharge rotor 10. A side wall 19 of housing 8 holds the plugs P in the flutes 13 for part of the travel of the delivery rotor 9 but below the rotor 9 the housing 8 and the gun block 2 are open so that rejected plugs P can drop away. The discharge rotor 10 comprises eight tubes 21 each of which is aligned with a flute 13. A buffer spring 27 secured to the housing 8 lies across the end of the lower part of the rotor 10 to contain the plugs P in the tubes 21. Each tube 21 has a bump 28 to slow the plugs down. A gap between the adjacent ends of the rotors 9, 10 accommodates an inlet 51 for a compressed air supply in position in line with the tubes 21 during the upper part of their travel. Stationary feed pipe 4 and the air inlet 51 are in line, a coupling member 32 with a laterally enlarged aperture guiding plugs P from the tube 21 into the pipe 4. If a plug P fails to enter its tube 21 properly or rebounds from the spring 27 out of the tube a photoelectric detector 36 is actuated, the rotors 9, 10 are stopped with the tube 21 containing the jammed plug P in line with a spring-loaded plunger 41 and compressed air is applied from a pipe 41 to eject the jammed plug P out through the opening in the housing 8. Fig. 7 shows an embodiment wherein the air jet 16 is replaced by a launching drum 46 having a plurality of spring-loaded studs 47 depressed by rotation under a cam 48 and released in line with the end of a plug P to flick it from the delivery rotor 9 to the discharge rotor 10. Figs. 10, 11 show an embodiment wherein plugs 102 from a magazine 101 are fed from flutes 112 on a delivery rotor 105 to chambers 113 in a discharge rotor 106 and from the chambers 113 into a barrel 103 by air admitted from a port 104 to an inlet 120 in line with the barrel 103.

The rod extends from an electric switch block 13 on the handle to the motor-fan assembly. The vacuum clearer is constructed so that the fan may draw either from the floor tool 4 or through the handle 5, delivering in each case to the dust-bag. The switch block is fixed to the hollow handle by a plate 15 carrying threaded posts 16 and by nuts securing the block 13 and its cover 20. It is formed at its upper end with a plug socket 22 connected through a spring 25 and earthing clips 24 with the bag-carrying rod 11 used for earthing and conveying the leads.

An "emergency exit" door panel 23 which can partake of a horizontal sliding movement and a pivoting movement about one vertical edge is secured about the vertical edge by means of a sole cantilever support and pivot assembly 29 adjacent the upper edge of the door panel for supporting the unbalenced weight of the panel, the assembly 29 comprising an upper hollow steel member 61 fixedly secured to a member 43 adjustably positioned over a lower portion 28 of the trussed trolley member for telescopic movement thereover and is secured to the trolley by pairs of screws 45, 47 to reinforce each other and the member 61 being received in the end of the bore 62 of hollow stile 55 of the panel with a close fit. A shaft 63 integral with the lower cantilever support and pivot member 57 extends through member 61 and is engaged by nut 65 to support the weight of the panel and needle bearings 67 are provided to enable nut 65 to be tightened sufficiently to prevent relative vertical movement between members 61 and 57 while accommodating the relative pivotal movement thereof. To prevent the bottom of the door from swinging out due to differential pressures, e.g. caused by wind a roller is secured to the lower end of the door to engage frictionally the threshold. A catch (Fig. 5, not shown) releasable under adjustable pressure is provided at the free ends of the panel 23 to fix the position thereof during sliding operation and can be released by pressure on the panels as by a crowd in emergency conditions. The sliding operation may be manual or power operated by an electrically controlled fluid pressure system (Fig. 9, not shown) and in the case of a building access door with two oppositely sliding doors simultaneously operated with pivotable sliding panels 21 on either side, the power control circuit automatically unlocks the panels 21 and when panels 23 are pivoted about the cantilever supports 29 by release of the catches aforementioned (Fig. 5), the panels 23 engage the free sides of panels 21 causing them to slide and pivot with the panels 23 as shown in Fig. 2 to open completely the door space whatever the momentary position of the panels 23 in their sliding paths.
