A product is obtained in which at least some of the copolymer or terpolymer is grafted on to the polyphenylene oxide, the remainder being in admixture therewith. The phenol may have the formula where R<SP>1</SP>, R<SP>2</SP>, R<SP>3</SP>, R<SP>4</SP> and R<SP>5</SP> are hydrogen or halogen atoms or hydrocarbon, halo-substituted hydrocarbon, cyano-substituted hydrocarbon, hydrocarbonoxy or halo-substituted hydrocarbonoxy groups, at least one being hydrogen and at least one being other than hydrogen. The copolymer or terpolymer is used in an amount such that the modified polyphenylene oxide contains from 0À5 to 20% by weight of the copolymer or terpolymer, at least some of which is grafted on to the polyphenylene oxide.

Abstract: 1372208 Differential electrolytic treatment of a planar article WESTERN ELECTRIC CO Inc 21 Dec 1971 [21 Dec 1970] 59303/71 Heading C7B [Also in Division H1] In a fluid, portions of a planar article are differentially treated, e.g. plated electrolytically or electrolessly, anodized, polished or cleaned. A plurality of the articles is arranged in a spaced radial configuration about a longitudinal axis and rotated in the fluid about the axis thereby providing more reaction of the fluid with the radially outer portions of the articles than with the radially inner portions. As illustrated in Fig. 5 Ni leads 11 for transistors are electro-plated with Au using an electro-plating bath 65 and an anode 67. The leads 11 are carried by a tubular member 33 which is rotated by a shaft 32 driven by a motor 61. The leads are joined together at one end by a strip and lengths of so-joined-together leads are mounted in slots 46 around the circumference of the tubular member 33. Current is supplied to the leads 11 through the shaft 32, a base 31 and the member 33. The Au is plated thickest on those parts of the leads furthest from the tube axis. The electroplating bath may be an acidic solution containing ammonium citrate and potassium gold cyanide. The leads 11 may be electrolytically pre-plated in a solution containing potassium phosphate and potassium gold cyanide. Fig. 6 (not shown) illustrates an alternative way of securing lengths of joined-together leads 11 in a cylindrical configuration. Each length is threaded at one end on a wire and is threaded at its opposite end on another wire. Each wire is fastened around a disc, the discs being arranged coaxially.

Abstract: 1337629 Steam boilers and propulsion system SCIENTIFIC ENERGY SYSTEMS CORP 23 Dec 1971 [29 Jan 1971] 59979/71 Heading F4A In a steam propulsion system for use in winter conditions, there is provided a first water storage tank 42 having a capacity to contain water frozen therein without damage, and a second water storage tank 32 with, e.g. a sump heater in order to give sufficient water to charge the boiler 14 through a start-up pump 48. When the boiler 14 is fired by a burner 16 fed from a fuel supply tank 24 the steam produced passes through valve 58, steam throttle 18 to an adiabatic expander 20 linked to drive a vehicle, and a feed pump 83 takes over from the startup pump 48 to continue the cycle. Steam also passes to a condenser 22 and thence water is fed back to the storage tank 32. Fig. 2 illustrates the sump heater 60 in the form of a wick-type burner 64 supplied with fuel from the tank 24 through an auxiliary fuel line 68 under the control of a temperature sensitive solenoid control 74 which operates, in turn, a valve 70 and an igniter (not shown) for the burner 64. A sealed pipe 76 contains a charge of water, or other vaporizable fluid, and the pipe has a bulb 78 at its lower end 78 and the pipe 76 extends into a water-filled open-ended shroud 80 located in the storage tank 32. As the entire system warms up, oil cycling through a coil 88 in the tank 42 will thaw the water therein to provide the necessary make-up water for the tank 32 as required. Other embodiments are described in the Specification (Fig. 12, not shown) wherein the sump heater is replaced by a shut-down sump container (152) and an insulated recirculating sump container (154) and an anti-freeze solution is used in the system. In a further embodiment (Fig. 9, not shown) the sump heater is replaced by an electric water heater. Fig. 5A shows a water storage tank in which is placed a resiliently compressible core 92 to prevent damage when the contents of the tank freeze.

As shown in Figs. 1 and 2 the vessel 10 comprises a closed cylinder of transparent synthetic plastics material of thickness about 0À01 inches, a release band 13, with a pull tab 14 being provided between an upper rim of the container 11 and a corresponding portion 12 of reduced thickness in the vessel. Pulling the release band 13 to open a package produces a discardable upper disc-shaped portion and a lower cylindrical portion which can be used as a drinking vessel. The vessel 10 may have a vertical fluting (27) to hold a drinking straw (28), Fig. 6 (not shown). In a modification, Figs. 4, 5 (not shown), the vessel 10 comprises a cylindrical cover as shown in Fig. 1 but formed of equal upper and lower cup portions (20, 21) a joint around the centre of the package being sealed by an external pullstrip (22). A cover vessel (31) for a bottle comprises a bottom cylindrical cup-part 32 and a disposable upper domed part (33), Fig. 7 (not shown), connected by a pull tab (34). The upper part (33) may be dispensed with in which case the bottom part (32) may be sealed by the strip (34) to the bottle (30).

Abstract: 1288120 Electro-physical measurementvolume J C ECKARDT A G 18 Dec 1970 [18 Dec 1969] 60237/70 Heading G1N The volume of liquid flowing in a duct is determined by voltages induced therein by its movement through an electromagnetic field, which is switched alternately into a vertical plane for measurement of speed of flow V and a horizontal plane for measurement of level H, the successive values U V , U H  being multiplied together. As shown a pair of coils 2, 3 surrounding the duct have their axes at 45 degrees to the vertical so that the resultant field changes from vertical to horizontal when the polarity (phase sense) of one coil is reversed. The level signal U H  from terminals 6 is applied through amplifier- 14, and compensator 11 to a store 7 and indicator 17. When time switch 8 operates reversing switch 9 to provide a vertical magnetic field, the flow signal now appearing at terminals 6 is passed via amplifier 14 and compensator 11 to adder 15 where it is summed with the stored level value from 7 and the result applied to recorder 22. To avoid 50~ mains interference the apparatus is preferably operated at another frequency e.g. 60 cycles, and a 50~ residual interference compensation is provided by unit 23.
