Title: Gas turbine power plant
Inventor: MARTIN PETER
IPC: F02B71/06
Filed: 1958-07-31
Abstract: 872,976. Gas turbine plant. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Aug. 12, 1959 [July 31, 1958], No. 24683/58. Class 110(3). A gas turbine plant comprises a free piston gas generator, a gas turbine, an annular combustion chamber forming a path for gas from the generator to the turbine and means, operable at will, for discharging liquid fuel across the inlet to the combustion chamber as a sheet of fuel and for igniting the fuel. A free piston gas generator 1 discharges to a gas receiver 2 having a main outlet 2a discharging into a duct 3 leading to an annular combustion chamber 4 feeding an axial flow forward drive turbine 5 which exhausts through a duct 11. A secondary outlet 2b is cormected to a duct 13 having branches 13a, 13b. The branch 13a having a control valve 15, leads to a reverse drive turbine 7 which discharges into the duct 11 through a duct 12 provided with a control valve 16. The branch 13a leads direct to the duct 11. A valve 17 controls the flow into duct 3. The combustion chamber 4 comprises inner and outer radially spaced annular walls 4a, 4b defining a flame tube and a casing 4c. The outer 4a is corrugated at 4d to form a plurality of longitudinally extending shoots corresponding in number to the number of inlet guide vanes of the turbine 5 which are adjustable to vary the nozzle area so that these vanes are subject to the coolant effect of the unheated gases which pass between the outer surface of the flame tube and the casing. The unheated gases are caused to flow mainly over the concave surface of the guide vanes as described in Specification 853,108. Fuel is injected into the flame tube by means of a rotary fuel distributing disc 18 driven by the turbine 5. Fuel is fed from a pipe 21 into the hollow upstream end of the shaft 19 and is admitted through apertures in the shaft into an annular trough formed on the downstream face of the disc. The rate at which fuel is supplied is adjusted so that under the effect of centrifugal force the fuel flows over the edge of the trough, spreads out over the rearward face of the disc and is discharged from the periphery of the disc as a sheet of fuel where it is shattered into droplets by the gas stream as described in Specification 853,110. The rearward face of the disc is inwardly coned at an angle between 1.5 and 5 degrees. Paddles may be provided on the rear face of the disc to assist mixing of the fuel and gas. The fuel supply to the combustion chamber may come into operation automatically when the throttle controlling the fuel flow to the gas generator 1 reaches a predetermined point.

Abstract: 205,095. Akt.-Ges. Brown, Boveri, et Cie. Oct. 9, 1922, [Convention date]. Addition to 186,036. Cut-out arrangements in which, by means of two time relays one with a short time setting and the other with a long time setting, a circuitbreaker when tripped is closed again a predetermined number of times, after which, if the overload persists, it is locked out, as described in the parent Specification, are adapted to a plurality of leading-out mains two relays only being necessary for all the leads. These relays are energized by means of contacts on the circuit-breaker of each feeder so that only the particular circuit-breaker on the overloaded feeder is opened. As shown in the Figure, applied to three parallel feeders, the circuit-breaker in each feeder is provided with three sets of back contacts e<1>, i<1>, k<1> connected with the re-closing coil m', with auxiliary busbars q, r, s, t, and with contacts of a locking-out relay p<1>. A single, short time-lag relay f and a single, long time-lag relay g control the successive re-settings for which current is obtained from the transformer h. After the allotted number of re-settings has taken place, the relay g closes, thereby supplying current through the back contacts k<1> to the locking-out relay which permanently breaks the re-setting circuit of the circuit-breaker in the feeder carrying the sustained overload. This circuit-breaker mav be reset by releasing the pawl o by hand.

Title: Improvements relating to the neutralisation of organic sulphonation and sulphation products
Inventor: VILLADSEN KARL JOHAN STAMPE
IPC: C07C303/44
Filed: 1952-10-06
Abstract: <PICT:0727275/IV (b)/1> Neutralization of organic sulphation or sulphonation products which are decomposable on neutralization is effected by bringing together the said products and a neutralizing agent in and passing them through a reaction space bounded by the adjacent walls of inner and outer bodies, one body being stationary and the other body being rotated and at least one of the walls being cooled by the passage of a cooling liquid in contact with the surface of said wall outside the space between the walls.  The method is described with reference to several suitable forms of reactor. Thus (Fig. 1), a reaction vessel 1 is provided with a rotatable body 2 filling up most of the space within vessel 1 but leaving a narrow space 3.  The sulphated or sulphonated product and neutralizing agent are introduced through branches 4 and 5 and the neutralized product leaves by branch 6.  Hollow journals 7, 8 provided for the rotating body 2 permit the introduction and discharge of a cooling medium. The vessel 1 may also have a cooling jacket.  The neutralization may be complete or only partial, in which event the discharged product is fed to an auxiliary vessel where additional neutralizing agent is added to complete the neutralization.  In another form of suitable reactor, the reactants are introduced at about the middle of the vessel, and the products are discharged from both ends of the vessel. Products which may be neutralized include those obtained by reaction of a sulphonating or sulphating agent on fatty alcohols or on the products produced by reaction of fats, fatty acids or other long-chain aliphatic carboxylic acids with glycerol, glycol or other di-, tri- or higher polyvalent alcohols, including condensation products of polyvalent alcohols, e.g. polyglycerol. Normally, alkali hydroxides or ammonium hydroxide serve as neutralizing agent; a carbonate or other salt generating gas in acid solution, e.g. sodium sulphite, may be present initially in the neutralizing agent or be added during neutralization.

Abstract: 462,976. Dandy - rolls. TROTMAN, W. E. K. Sept. 12, 1935, No. 25344. [Class 96] In a dandy-roll for use in paper-making and allied industries, the liquid permeable surface is composed of upper and under layers of non - woven or non - interlaced structure each formed of close set parallel courses of fine wire, the wire courses of the upper layer crossing those of the under layer without being interwoven or looped therein. The liquid permeable surface is formed of an under layer 1 comprising parallel lengths of fine wire, e.g. <1>/50" to <1>/64" diameter at a distance apart substantially equal to the diameter of the wire, and an upper layer 2 comprising a single length of fine wire, e.g. <1>/100" to <1>/128" diameter coiled around the layer 1 in the form of a spiral with a pitch preferably approximately equal to the diameter of the wire. If desired, one surface may be formed of lengths of wire disposed in parallel courses with a large pitch helical formation, or of close set circumferential wire rings. To simulate a wove surface, the top layer 2 may be embedded in the lower layer 1 so that their surfaces are substantially flush. The top layer 2 is positioned by being tinned and coiled on while the tinning coating is still hot. The supporting skeleton comprises a series of lightened longitudinal bars 4, carrying a coarse spiral 5 of stiff wire. Longitudinal lengths of coarse wire 6 are placed between the bars 4. Watermarks and wires for producing laid lines may be applied to the roll surfaces.
Patent GB-388831-A (GB)
Title: Improvements in or relating to the production of films and sheets
IPC: C08L1/08
Filed: 1931-09-10
Abstract: Smooth sheet-like material is obtained by forcing a highly concentrated solution of a cellulose derivative under pressure through a slit-shaped orifice and receiving the shaped product directly on a supporting surface which may be of polished metal, glass, or baked synthetic resin.  The supporting surface may be the periphery of a rotating wheel, or a moving band of metal or paper, or it may be a stationary surface.  The cellulosic solution may be placed in a hopper and subjected to fluid pressure whereby it is forced through the slit, or it may be fed to the slit by means of gear pumps.  The hopper may be provided with a heating jacket or coil.  The solution may be extruded on to the supporting surface at an angle other than a right-angle.  If desired the supporting surface may travel at a greater speed than the speed of extrusion, in order that the sheet may be stretched and reduced in thickness.  In an example, a 30 per cent solution of cellulose nitrate in acetone and camphor is fed through a slit from a hopper and under a pressure of 5-75 lbs. per square inch above atmospheric pressure on to a polished nickel wheel, and the volatile solvent is evaporated, leaving a smooth sheet.  Higher concentrations of cellulose derivative such as 66 per cent and over may be employed.  The cellulose derivative may be cellulose acetate or other cellulose ester, or ethyl cellulose or other cellulose ether.  Cellulose derivatives of low viscosity characteristics may be employed.  In addition to the volatile solvent, the solution may contain a plasticizer such as camphor, triacetin, an alkyl phthalate or tartrate, or monomethyl xylene sulphonamide.  The solution may also contain pigments, effect materials, stabilizers such as urea, and other ingredients.  Thin sheets for wrapping foodstuffs, tobacco products and other articles, or thicker sheets for photographic, cinematographic and other purposes, may be obtained.  The Specification as open to inspection under Sect. 91 comprises also the use of a doctor blade for spreading the solution of cellulose derivative upon the casting surface.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in hand-power looms for weaving
IPC: D03D29/00
Filed: 1921-09-30
Abstract: 192,443. Roberts, L. W. Sept, 30, 1921. Picking-motions.-In a hand-power loom, each picker-stick 12, Figs. 4 and 5, is connected by a cord 21 passing over a pulley to a weight 23. When the lay is swung forwardly, each cord 21 is tensioned and draws a picker-stick to the outer end of the shuttle-box against the action of a spring 24, the sticks being held in that position by engagement with catch fingers 25'. On the return of the lay, one or other of the fingers is raised through a cord connection 33 to a handcontrolled slide 27 on the lay, and a spring 24 then operates the picker-stick. In a modified arrangement for preventing more than one picker-stick from operating at the same time, the picker-sticks are moved into notches in the shuttle-boxes when the lay moves outwardly. When the lay returns, a projection on the end of one of the picker-sticks engages an arm on a ratchet-operated wheel. That picker-stick is thus freed from the notch in the shuttle-box and is operated by its spring to pick the shuttle. The picker-stick at the other side of the loom passes between two radial arms on a similar ratchet-operated wheel and thus remains looked. According to the Provisional Specification, picking is effected by rollers on the lay moving levers, cams, &c. against springs.
