Title: Improvements in or relating to electric steam irons
IPC: D06F75/36
Filed: 1958-03-03
Abstract: 827,695. Steam irons. ROWENTA METALLWARENFABRIK G.m.b.H. March 3, 1958 [March 2, 1957], No. 6722/58. Class 138 (2). An electric steam iron includes an adjustable valve (5, 5a) for regulating inflow of water from a reservoir (4) to a steam generating chamber (35) and a vertically guided valve-operating rod (24) within a pipe (17) through which water is supplied to the reservoir, the upper end of the rod being engaged by an eccentric (19d) disposed in the pipe on a shaft (19) that extends perpendicularly to the rod axis and has a squaresectioned portion (19c) which is engaged by the arms (20) of a leaf-spring secured to a steamtight closure cap (22) for the pipe through which the said shaft (19) extends laterally for manual operation (knob 18). As shown, the eccentric acts upon a U-shaped member 25 riveted at 24a to the valve rod top; while a spring-loaded anti-splash washer 29 of diameter somewhat less than that of pipe 17 is carried on the rod where the pipe 17 opens into the reservoir 4, and an anti-surge plate 32 is also provided.

Title: Process for producing a covering by pipe blasting or spraying of articles more particuly articles sensitive to thermal shock
IPC: C23C4/12
Filed: 1972-02-14
Abstract: 1477299 Coating COMMISSARIAT A L' ENERGIE ATOMIQUE 14 Feb 1972 [24 Feb 1971] 6734/72 Heading B2E [Also in Division C7]  In a process for the spray coating of articles, more particularly articles sensitive to thermal shock, each zone of the article is covered by a sequence of very short spraying steps separated from one another by comparatively very long cooling stages, so that the mean temperature of the article remains low and substantially constant and the minimumto-maximum temperature spread is low in a zone being sprayed. The coverings may, for example, be refractory oxides on ceramics or metals.  In the apparatus for coating tubes shown in Figure 2, a continuously-moving support member in the form of a wheel R is mounted on four rollers 1, 2, 3, (4), the rollers 1, 2 being interconnected by a sleeve 6 and rotated by a motor M. The wheel R comprises two annular rims 7, 8 interconnected by a number of sheaths 9 which house the tubes T to be coated, in this case ceramic tubes to be coated with alumina. The sheaths 9 and tubes T are moved by the wheel R past blowpipes P 1 , P 2 , P 3 , P 4 . two operating axially and two laterally of the tube ends. The sheaths 9 are retained laterally in the rims 7, 8 by idler rollers 10 and are rotated by rollers 11 (shown in detail in Figure 3). As they rotate, the rollers 11 rotate the sheaths 9-and the tubes T which they house. The rollers 11 are in turn rotated by two belts 12, 13 which engage with each roller 11 and also run round the sleeve 6 interconnecting the rollers 1, 2. Each zone of the tubes T is presented to any blowpipe only once for revolution of the wheel, the remainder of the revolution being for cooling. Advantageously, each zone remains for only a fraction of a second before each pipe and the cooling time is e.g. from 100 to 120 times longer than the spraying time. Secondary cooling may be provided by means of fans or blowers. For flat articles, e.g. plates, an endless conveyor belt to which the plates are secured may advantageously be used to move the plates past blowpipes.

Title: Improvements in or relating to aeroplanes and like aircraft having folding wings
IPC: B64C3/56
Filed: 1926-03-11
Abstract: 274,151. Fairey, C. R. March 11, 1926. Planes, arrangement of; steering.-In an aeroplane having wings which can be folded backward when not in use, and a tail plane variable in incidence, the variability of the angular position of the tail plane is utilized to actuate locking means for securing the wings in their folded position and if necessary for partially or wholly supporting their overhanging weight. In the case of a biplane or multiplane, the fairing 17 of a strut interconnecting the ailerons is provided with a notch 18 in the upper edge of which is a recess 20 adapted to be engaged by a rod 12, projecting from the leading edge of the tail plane, when the tail plane is tilted upwards. The front edge of the tail plane is raised by screw-and-nut mechanism acting on the front or rear spar and turned by cables from the pilot's seat, so that the rods 12 can support the overhanging weight of the main planes without reacting on the pilot's control. A monoplane also is described in which the rods 12 engage a notched member beneath the rear spar of the folded plane, and in further modifications folding monoplane wings adapted to be turned also about the front or rear spar until they are in an approximately vertical position parallel to the fuselage are provided with notched members on top or underneath the rear spar for engagement with the rods 12. The angular adjustment of the tail plane may be transmitted by cables or lever and link mechanism to other locking-mechanisms, for example a rotary transverse tube on the fuselage having arms at its ends for engaging elements on the wings.

Title: Method of treating plastic wax-like surfaces to render them receptive to printing ink, colours and the like
IPC: B29C59/10
Filed: 1955-03-09
Abstract: <PICT:0765545/IV(a)/1> <PICT:0765545/IV(a)/2> <PICT:0765545/IV(a)/3> <PICT:0765545/IV(a)/4> A web or article of polyethylene or the like is treated to render it receptive to printing ink, colouring, adhesive or the like by exposing it to a high voltage electric discharge between spaced electrodes.  The web 20, Fig. 2, may be passed over a roller 22 under a gas-filled discharge tube 23 spaced from the roller.  The roller and the tube are connected to opposite poles of a high voltage so that a corona discharge exists between their A.C. or D.C. supply.  The discharge tube may be replaced by a conducting blade or wire but this involves the danger of arcing where the web is thin or punctured, which danger is avoided by using the gas-filled discharge tube 23.  The ends of the tube may be surrounded by insulating sleeves so that the marginal edges of the web are untreated.  To speed up the process the web may be passed over a series of rollers 22 each having a discharge tube 23 spaced a short distance away from it.  All the rollers may be connected to one pole of the source of supply and all the tubes connected to the other. The series of rollers may alternatively be replaced by a single roller of larger diameter, a series of tubes being spaced a short distance away from the roller surface.  For treating both sides of a web simultaneously the supporting rollers 47, Fig. 6, are arranged alternately on opposite sides of the web and the co-operating discharge tubes 48 are likewise placed alternately on opposite sides of the web.  The rollers and tubes on one side of the web are connected to one pole of the supply and those on the other side are connected to the other pole of the supply.  The outer surface of a cup-shaped article 55, Fig. 7, is treated by placing a roller 57 inside the cup and a discharge tube 58 outside.  The article may be rotated on a turntable 62.  A web 65, Fig. 8, is treated on both sides by passing it over a roller 66 forming one electrode, the web being spaced from the roller by a layer 67 of an insulating semi-porous material such as paper or cloth.  The discharge tube 69 is spaced from the web as before and connections are made from the poles of the supply to the roller and the tube.  By this means both sides of the web are subjected to an electric discharge.  Ozone, formed by the discharge modifies the surface of the web in such a way that it becomes receptive to printing ink, colouring or adhesive.

Lubricant conveyed by fluid.-An air-line oiler comprises a casing B having an internal wall C dividing the casing into an oil chamber D and a passageway E for the primary fluid, the passageway being in the form of a Venturi tube, A piston 0 is disposed in the chamber D and a passage P in the wall C communicates at its ends with the ends of the chamber D. A plug valve Q arranged in the passage P is provided with passages R, T U. An oil storage reservoir j partially surrounds the chamber D and communicates with the passages P through a passage q provided with a needle valve r. The reservoir j also communicates with the enlarged part H of the passageway E through a pa,ssage t provided with a check valve s. With the valve Q and pistons 0 in the positions shown, the left-hand end of the chamber D communicates with the enlarged part H of the passageway E through the passages P, R, and a passage S, while the right-hand end communicates with the restricted part K through the passage P, U, T, a passage b, and an adjusable nozzle X. Due to the pressure differences at the parts H, K, the piston 0 is therefore moved to the right, forcing oil through the nozzle X. At the end of the stroke of the piston, the. valve Q is turned through 180‹ and the valve is opened. Oil is therefore forced from the reservoir j into the right-hand end of the chamber D. returning the piston to the left. The valve Q is then restored to its original position and the valve r closed.

Abstract: 418,726. Furnaces for burning refuse and low-grade fuel METALLGES. AKT.-GES., 45, Bockenheimer Anlage, Frankfort-on-Main, Germany. March 6, 1934, Nos. 7185 and 7186. Convention dates, May 20, 1933 and Aug. 1, 1933. [Class 51 (i).] A method of burning lowgrade fuel, especially refuse, consists in feeding it to a grate where it is ignited and during combustion is compressed or compacted in one or more operations before it has been converted into clinker, the free space resulting from compressing the fuel being filled with a fresh charge. Fig. 1 shows a furnace in which the method of combustion is carried out comprising a grate 2 with blast chambers 5, 6, 7 beneath. A pusher plate 3 is employed for compressing the fuel and for finally discharging clinker into a clinker pit 11 through the door 15. Doors 14 on the pit 11 permit the clinker to fall into a conveyer truck 19. Fig. 3 shows a modification in which the fuel is dried before being fed to the grate. Fuel is fed to the drying-chamber 33 where it is met by gases drawn from the furnace 22 and through perforated walls 34, 35 by a fan 42 which delivers the gases to the chamber 26 beneath the grate. The dried fuel is fed on to the grate 23 by a screw 44 and ram 46 and is consolidated by a ram 30. The clinker is discharged into a pit 31. Specifications 323,841, [Class 51 (i)], and 390,015 are referred to.

Title: Sound suppressing panels
IPC: G10K11/172
Filed: 1974-02-18
Abstract: 1456302 Gas turbine jet propulsion engines GENERAL ELECTRIC CO 18 Feb 1974 [1 March 1973] 7240/74 Headings F1G and F1J [Also in Division F2] A sound suppressing panel for use in making ducts, e.g. gas turbine engine ducts, comprises a face sheet or first wall 26 for bounding the duct cavity 12, a backing plate or second wall 30 spaced from the first wall, and a plurality of spaced partitions 34 each extending between the first and second walls 26, 30 to form between them a plurality of resonator cavities 28, at least two adjacent partitions 34 forming acute corresponding angles 36 with the second wall 30. The wall 26 is porous or otherwise permeable by sound waves while the wall 30 is sound wave impermeable. A second plurality of spaced partitions (40) Fig. 3 (not shown) extend axially between the walls 26, 30. The partitions 34, (40) are impermeable to sound waves. In sound suppressing operation, each cavity 28 operates in the Helmholtz regime to suppress sound energy as a function of the cavity depth d in a pre-selected frequency band whiile the canted disposition of the partitions 34 enables each cavity 28 to be sized to also suppress a second and higher frequency band in the quarter-wave tube resonator regime as a function of the cavity length x. Whereas the depth d is the radial distance between the walls 26, 30, the length x is measured along a line parallel to the partitions 34. In a situation where the sound to be suppressed comprises many frequency ranges it is preferable that the partitions 34 are arranged in pairs with the partitions in each pair being inclined parallel to one another but with the angles of inclination differing from one pair to the next Fig. 4 (not shown). In this case the quarter-wave tube resonant frequency varies among the cavities since the various cant angles difine different cavity lengths. This invention provides a sound suppressing treatment for the wall defining the inlet duct of a gas turbine engine, or for similar duct surfaces throughout the engine such as the wall defining the fan duct and the surfaces of the exhaust nozzle.

Abstract: 589,469. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., TAYLOR, R., and BAKER, G. T. March 23, 1945, No. 7327. [Class 40 (iv)] In a system in which the line switches or line finders are provided with in extra bank for metering, when the first selector is set to a level giving access to outgoing toll lines, the connection to the metering bank is transferred to an additional wiper of the selector and identification signals for the purpose of ticketing are sent thereover. The identification equipment is assumed to be of the kind disclosed in Specification 539,823 in which a code marking is provided for each line, the metering wire in this case being connected through non-linear resistance units to common points to which A.C. signals are applied. In Figs. 1, 2, the first selector has two sets of wipers, and the metering wire M is connected on a local call through a rectifier MRA to the test wipers P1, P2 to which positive battery is applied to actuate the meter MTR connected between the metering wiper D5 and the earthed homing bank D1 of the line switch. On levels allotted to toll lines, only one set of wipers gives access to outlets, the P2 terminals are earthed, the +2 terminals are left unwired and the - 2 terminals are connected to identification wires I extending to the outgoing relay sets. When the selector is set to such a level, post springs NP are operated to transfer wire M to wiper -2. The meter MTR may be actuated by a pulse over wire I if required. In this arrangement, there is a drain of signalling energy through the meters of lines in a calling condition, and in a modification for obviating this, Figs. 3, 4 (not shown), the meter MTR is connected between the test wiper D4 and the metering wiper D5, and wire M is normally earthed in the selector over post springs NP and rectifier MRA. When identification is required, positive battery is fed back over both wipers - 2, P1 to bias the resistance units of the calling line while shunting the meter. A jack MRTS is provided for routine testing, the meter being connected to test lead 12 when the line circuit is seized over a test selector.
