Title: Improvements in and relating to apparatus for collecting measured quantities of liquid
Inventor: SNOW ARTHUR
IPC: G01N1/18
Filed: 1957-04-17
Abstract: 860,567. Filling containers with liquid. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 17, 1958 [April 17, 1957], No. 12545/57. Class 125(2). In apparatus for collecting fractions of liquid in vessels 11 which are moved successively under a supply 18, the vessels are disposed in a spiral about the axis of turntable 14 driven by means which directly provides the necessary rotational and translational components between the vessels and the supply. There is a constant centre to centre distance between adjacent vessels in the spiral. As shown, vessels 11 are supported on turntable 14 by an apertured plate 12 the apertures 13 being equally spaced on a spiral path. The turntable is rotatable about an axle 15 carried on an arm 16 itself rotatable on end of a bar 17. Turntable 14 is fitted with a plate 19 having an array of apertures 21 the same as that of apertures 13. Apertures 21 are engaged successively.. by the hemispherical bodies 23 carried on a shaft intermittently rotated one step by an electric motor 24. Thus the turntable is rotated step by step about its own axis and gradually about the axis at the end of bar 17 to bring vessels 11 under the liquid supply 18. The plate 19 may have hemispherical bodies successively engaged by apertures in a member driven by the motor. Other forms of toothed drive may be used. As shown the motor is controlled by a drop-counter 31, 32 utilizing a photoelectric effect. Alternatively the drops may be detected by the change in capacitance between two electrodes as they fall between them. The counter may emobdy a decade selector for changing the range. In another form the drops collect on a small ring on the end of a balance arm which then tips over to make contacts to start the motor. Instead of dropcounting, supply 18 can include an electricallycontrolled valve delivering a measured quantity, or may discharge into a syphon tube or counterbalanced tipping bucket. The plate 12 can be replaced by another having different apertures to receive vessels of a different size. To prevent dropping during the vessel movement, the vessels may have enlarged mouths. According to the Provisional Specification, the apertures in plates 12, 19 can be arranged in concentric circles, the plates being moved about the end of arm 17 after such complete rotation.

Title: Process for the impregnation of styrene-polymer granules with blowing agent
IPC: C08J9/18
Filed: 1965-03-25
Abstract: Particles of styrene polymers are impregnated with a blowing agent by stirring the particles intensively, together with a finely-divided inorganic solid and a liquid blowing agent, at a temperature above 30 DEG  C. but below the softening point of the polymer, using a volume ratio of blowing agent to polymer greater than 1:1, preferably greater than 3:1.  The styrene polymer may be a homopolymer or copolymer, e.g. with butadiene, divinylbenzene, a -methylstyrene, acrylonitrile or acrylic esters, and may also contain other polymers, e.g. polyethylene, fillers, pigments, flame retardants and foam stabilizers.  The term "particles" embraces all particulate configurations.  Specified blowing agents are halogenated and unhalogenated aliphatic and cycloaliphatic hydrocarbons (examples are given) having a b.p. between 25 DEG  C. and the normal softening point of the polymer; if the blowing agent boils below 30 DEG  C., external pressure is applied to liquefy it during impregnation. Specified inorganic solids are CaSO4, hydroxyapatite, CaCO3 MgCO3, vermiculite, kieselguhr and mixtures thereof.  The impregnated particles may be foamed by heating, e.g. by use of steam in a perforated mould.

Title: Method of and apparatus for evaluating electrical service
IPC: G01R11/56
Filed: 1936-05-08
Abstract: 464,962. Supply meters. WILLIAMS, A. R. May 8, 1936, No. 13015. [Class 37] A method of evaluating electrical service to a consumer comprises measuring the total energy supplied in Kilowatt-hours, and periodically during selected periods of time adding to such measurement a quantity which is a direct function of the consumer's demand during the selected period. The selected periods are those of maximum demand on the supply system as a whole. A further addition may be made at the selected period in accordance with the power factor of the consumer's load. In the arrangement shown, a set of indicating dials 16 is operated by a kilowatt-hour meter 11 and a kilovolt-amperehour meter 12 connected to the mains 13 in the usual manner. The shaft 17 of the meter 11 is provided with a worm 18 engaging a worm wheel 19 on a shaft 20, which has two differential gears 21, 22 interposed between the worm wheel and the indicating mechanism. The meter 12 is mounted on a hollow shaft 23 carried by the shaft 17 but free to rotate thereon. The shaft 23 drives a shaft 27 through a worm 24, worm wheel 25 and bevel gearing 28, 29, two differential gears 30, 31 being interposed between the worm wheel 25 and a clutch 32. The shaft 17 is also provided with a worm 33 engaging a worm wheel 34 on a shaft 35 provided with a worm 36 engaging a worm wheel 37, which is arranged as the ring gear for the differential gears 30, 31, whereby the shaft 35 can drive the shaft 27. The clutch 32 is operated at selected periods by a solenoid 39 to connect the shaft 27 to a shaft 38 provided with a worm 40 engaging a worm wheel 41 forming the ring gear for the differential gears 21, 22. The solenoid 39 is energized at the selected periods by means of a relay 43 responsive to currents of definite frequency which may be superimposed on the power lines 13 by a frequency generator 44 operated at definite times by a clock 45. In operation, the meter 11 operates continuously while the consumer is using electrical energy and measures the total consumption in kilowatt-hours. The meter 12 operates continuously, but is connected to the indicating mechanism only at such times as the clutch is engaged, e.g. for a period of say one hour when the system load is at a maximum. The kilowatt demand during this period is also communicated to the indicating-dials from the meter 11 through the worm 33 and worm wheel 34. In a modification, for use in cases where the consumer's load is at substantially unity power factor, the meter 12 is omitted.
