Abstract: 1,026,973. Delivering measured quantities of liquid. NOVIMA A.G. Feb. 1, 1963 [Nov. 12, 1962], No. 4188/63. Heading B8N. [Also in Division B1] An apparatus for dispensing measured quantities of liquid, such as a liquefied gas, comprises one or more measuring chambers 13, in each of which a floating piston 14 is reciprocated by alternately admitting the liquid to one side and then to the other side of the piston, wherein in each delivery conduit 11, 12 from the or each cylinder a back-pressure device 25 is provided, whereby the piston is subjected to a back pressure on its delivery side sufficient to prevent evaporation of the liquid in the cylinder. The ends of the measuring chamber 13 are connected by conduits 9, 10 to a slide valve 7 which, via an inlet pipe 6, is connected to the output side of a pump 3, the latter drawing liquid from a container 1. The slide valve 7 is provided with a control piston 8 which is actuated by means of compressed air, in a cylinder 15, under the control of valves 18 in the measuring chambers. In operation, with the apparatus in the position shown, the pump 3 feeds liquid through the pipe 6, valve 7, conduit 9, into one end of the chamber 13, thereby moving the piston so that the liquid on the other side thereof is forced through conduit 10, valve 7, pipe 12, backpressure device 25, non-return valve 26, pipe 27, into a container 29, the latter being held in contact with a filling head 28 by a compressedair operated piston 33. At the end of the stroke of the piston 14, the latter actuates one of the valves 18 so that, after an empty container 19 is connected to the filling head and a manually-actuated valve 17 momentarily operated, compressed air is fed to one end of the slide valve 7, thereby reversing its position shown and thus permitting liquid to flow through pipe 6, valve 7, conduit 10 to act on the opposite side of the piston 14; the liquid is then dispensed into the container via conduit 9, valve 7, pipe 11, back-pressure device 25 and non-return valve 26. The back-pressure devices 25 are either fixed or variable throttle or pressure relief valves. An adjustable stop 19 is provided for varying the travel of the free piston. In a modification, two sets of identical apparatus are coupled together so as to feed measured quantities of different liquids into the container via a mixing device (see Division B1).

Title: Improvements in or relating to the manufacture of wired glass
IPC: C03B13/12
Filed: 1962-02-05
Abstract: <PICT:0979314/C1/1> Wired glass is made from a web of wire, formed from longitudinal and transverse strands welded together at their sections, by feeding the web into the narrow end of a "bolster" of molten glass which, in plan, is of tapering form, the transverse strands being thus heated progressively along their length so that the relative expansion between adjacent strands is so small that deformation of the web is avoided.  A stream of molten glass 8 is fed from a furnace between casting rolls 5, 6 and over an apron 10 to a second pair of casting rolls 11, 12.  A second stream of molten glass 14 is fed along a spout 13 which may be of shallow V-shape in cross-section so that a greater amount is fed along the middle than the sides. This second stream is fed over the roll 11 and forms a "bolster" of V-shape on the first stream, the apex of the V pointing in a direction contrary to the flow of the stream, the formation of the V-shape being aided by water-cooled guides 17 supported above the stream.  The wire web 2 is fed by a spiked roller 22 under the guides 17 into the apex of the V and is thus incorporated into the ribbon of glass.  In a modification, the second stream is confined to a narrow width in the centre of the first stream and spreads out sideways to form the " bolster." Auxiliary heaters at the sides of the stream may be provided to ensure uniform heating. According to a further modification, the end of the spout 13 is a straight line inclined to the direction of flow so as to form a straight " bolster." Other alternative forms of spout are also described. Corrugated or patterned ribbon may be produced.  Specification 769,692 is referred to.
