Title: Improvements in or relating to wire brushes
IPC: A46D3/05
Filed: 1953-11-03
Abstract: 756,749. Making brushes. GEM BRUSHES (LUSON), Ltd., [formerly LUSON & SONS, Ltd., A.], and GROSZ, E. Feb. 2, 1955 [Nov. 3, 1953], No. 30382/53. Class 83 (2). [Also in Group XXIII] A brush strip of the kind in which the brush material is secured in a channel form metal strip is made by winding the brush material around the two parallel spaced wires, forming two metal strips into channel sections gripping the brush material over the respective parallel wires and then cutting the brush material between the wires. In the machine shown the two parallel wires 14 are drawn through a wire straightener 15 and hollow shaft 12 to a former 25 which maintains the wires accurately spaced. Wire brush material is wound round the parallel wires at the former by a disc 13 from reels of the wire mounted thereon. Two flat metal strips 30 are fed through punches 36 which form fangs in the edges of the strip on to clenching rollers 31 which double the strips about the wires forcing the fangs into the brush material. The strip so produced is drawn forwardly by rollers 37 to a reciprocating cutter which divides the strip into two parts 14. Variable-speed drives 21 and 33 permit the nature of the brush to be varied. The brush strip produced will be cut into lengths which may then be formed into annular sections and mounted on a suitable holder to form a rotary wire brush. A number of such sections may be clamped together side by side or alternatively a long length of the strip may be wound into helical form and secured between end plates.

Abstract: 934,757. Paper-making. BOWATER RESEARCH & DEVELOPMENT CO. Aug. 30, 1961 [Sept. 2, 1960], No. 30426/60. Class 96. [Also in Group XIII] Liquid in or on a flexible continuous sheet material in a machine glazed paper-making machine is evaporated by passage over one or more heated rollers 22, Fig. 2, each having a drying hood 20 thereabout containing pressure chambers 30, 32 ... 40 arranged transversely to the direction of movement of the material and individually supplied with heated air from a common manifold 42. The air is delivered to the material through apertures 50, Fig. 4, and thereafter exhausted by flowing transversely of the material and through openings 56 to exhaust passages, e.g. passage 44, formed between each pair of pressure chambers and spaced apart transversely of the direction of travel of the material. The cross-sectional area of the outlet apertures 50 is less than that of the exhaust openings 56 to ensure the velocity of the impinging air maintains the material in contact with the cylinder 22. The air is circulated by fans 70, one being shown in Fig. 3, having their inlets mounted in a supply chamber 68 in which the air is heated by steam-filled, finned pipes 76 or by an electrical or fuel burner, a portion of the moisture-containing air being bled off through exhaust ducts 100 and fresh air supplied through duets 102. The rate of supply of drying air to each chamber from the manifold 42 is controlled by a shutter 92 controlled by a Bowden cable 94 which covers or uncovers a cusp-shaped port 90 in a wall 88 between the chamber and manifold sQ as to obtain an even moisture distribution transversely of the finished web of material. The hood is pivotable on a framework 120 at one end of the cylinder 22 and to a piston-rod 122 at the other end. In a modification, the pressure chambers are not spaced apart by positioning the exhaust passages therebetween but adjoin one another, the exhaust passages which extend circumferentially of the drying cylinder being mounted within the pressure chambers themselves.

Means may be provided in the parallel resonant circuit for producing a further resonant frequency including at least one harmonic of the fundamental frequency. As shown, the valve 6 acts as an R.F. class C amplifier pulsed with a signal of the fundamental frequency, the Kerr cell has a capacity of 60 pf and typically is placed in series with a capacitor 2 of 500 pf. the parallel resonant circuit is tuned to the output harmonic desired, and a voltage of several kV is applied at 9. A capacitor 10 may tap across part of the inductance and a diode 4 may shunt the Kerr cell. Such a circuit causes the voltage applied to the cell to include a first harmonic cosine component while removal of capacitor 2 and diode 4 results in an applied voltage include a second harmonic sine component. Simple removal of capacitor 10 gives a steady component as well as the sine wave which alone is present if capacitors 2 and 10 and diode 4 are removed from the circuit. Shutter transmissions for these different arrangements are depicted in Figs. 2 to 5 of the Figures (not shown). The exposure time:frame interval may be from 1 : 2 to 1 : 4.5 and an exposure frequency of 10 mc/s. with exposures of 35 mÁ sees. can be obtained.

Abstract: 1285319 Casting moulds and processes; mould jackets UNITED AIRCRAFT CORP 1 July 1971 [14 Aug 1970] 30796/71 Heading B3F [Also in Division B5] Single crystal turbine blades are cast in a mould assembly comprising a number of articleforming moulds 2 (Fig. 2) in an annular jacket 22, 24. The mould assembly is made by providing a wax-pattern of a turbine blade 4 having at the lower end a helical passage 12 and cavity pattern 14, and at the upper end a runner pattern 10. Several such patterns are invested and the thereby formed article moulds are arranged in a ring with the turbine blade aerofoil leading edge of one mould adjacent the turbine blade aerofoil trailing edge of the next mould. Between the article moulds are spaces which are filled with wax 20. For each piece of wax 20, runner patterns 26, 28 are provided. At the top of the article moulds is placed a wax disc pattern 18 which will form a common sprue and which will interconnect runner patterns 26 and 10. The pattern assembly so-formed is reinvested to form a double walled mould assembly comprising article moulds interspaced by cavities and arranged in an annulus 22, 24. The wax patterns are melted out, and the mould assembly fired and placed within a furnace on a chill plate 30 so that cavities 14 and runners 28 are open to the chill plate. The mould assembly is preheated to above the melting temperature of an alloy to be cast therein. Alloy is poured and fills both the article moulds and cavities therebetween. Solidification commences from the chill plate upwardly in both runners 28 and cavities 14. The helix 12 selects a single crystal article to grow into the article moulds whilst columnar growth continues into the cavity. Heat is removed from the article moulds not only from the helix 12 but also from the cavities thereby increasing the rate of solidification of the single crystal turbine blades. In an alternative embodiment, the turbine blade faces of adjacent moulds are arranged opposing one another in the mould assembly.

Abstract: 1374835 Boiler KRAFTWERK UNION AG 30 June 1972 [30 June 1971] 30870/72 Heading F4A In a boiler in which water is passed by a feed pump 7 through tubes 1 defining the walls of a combustion chamber and through tubes 4 defining a partition subdividing the chamber, a control device 11, responsive to temperature measurement stations 14, 15 and to flow rate sensors 12, 13, adjusts control valves 10, 11 to maintain the temperature of steam at the outlet of the partition tubes below that at the wall tubes outlet. The example shown has tubes 1 helically coiled and tubes 4 arranged vertically with a steam temperature of 400-450‹ C. at the outlet of the wall tubes and the steam output from the partition tubes in a dry saturated state. As shown the feed pump 7 feeds water through an economizer 8 prior to the tubes 1, 4 and the output from the tubes is passed through superheaters 24, 25. Water separator systems 18, 19 are provided for each set of tubes and water from tubes 4 is recirculated by pump 22 to the inlet of the wall tubes via a valve 21 operated by a water level control in the separator 19. A line 26 may be employed to by-pass the economizer if required, valves 91, 10<SP>1</SP> being operated by the control device 11. In alternative arrangements water from the separator 19 can be passed by pump 22 to the partition tubes 4 or via heat exchanges to a point upstream of the feed pump 7; the partition tubes may be operated as a natural circulation system with return tubes leading to the inlet of the tubes 4. The controller may be indirectly responsive to the outlet temp. of the heating partition 4 by being controlled by the water level maintaining system 20, since if the valve 10 or 10<SP>1</SP> is so regulated that a specific water level is present in the separator 19, it follows that a steam saturation temperature prevails at the outlet of the partition 4.
