Title: Forming laminated glass containers from a composite encapsulated gob of molten glass
Inventor: BARKHAU MARVIN L
IPC: C03B5/04
Filed: 1988-01-29
Abstract: A glass bottle forming system is described in which a main glass melter is connected to a forehearth with a fairly conventional feeder provided at the delivery end of the forehearth. The feeder opening in the bottom of the forehearth is closed by a first orifice member through which a molten core glass will flow. Beneath the first orifice there is positioned a second orifice member that has an orifice that is slightly larger than the orifice in the first orifice member. A small melter contains a glass of essentially the same composition as that in the main melter, but with a coefficient of expansion slightly less than that of the core glass. This lower expansion glass is fed to the second orifice member so that it can flow out of the orifice with the core glass in surrounding relationship with respect thereto. The skin glass melter is connected to the second orifice member by a gravity feed system in which the connection is thermally controlled so that the viscosity of the two glasses are maintained essentially the same. Two embodiments of the skin melter and the second orifice are disclosed. In one embodiment the second orifice is vertically adjustable so as to vary the volume of skin glass flow relative to the core glass flow. The second embodiment has the second orifice supporting an annular bushing that is vertically adjustable and it cooperates with the bottom of the upper orifice member to regulate the flow of glass into surrounding relationship to the core glass coming through the first orifice member.

Title: Uninterruptible power supply for an electronic computer
Inventor: SUEN VICTOR
IPC: H02J9/06
Filed: 1989-11-03
Abstract: In the event of loss of normal AC mains supply, the computer is supplied from a battery F via an inverter E the frequency of operation of which is varied, preferably over the range 45 to 85 Hz, in dependence on the load current sensed by a monitor A so that the power output of the inverter E meets the demand. Software within the computer checks on the energy level remaining in the battery F and when this level reaches a predetermined value the software inhibits further normal computer operation and executes computer shut-down by storing the contents of a volatile memory K on non volatile media J followed by switching off the computer and VPS. The computer software performs a check when the computer is first switched on to determine the type of battery in use and thereafter the state of the battery is compared with known discharge characteristics of that battery to determine the remaining battery energy level. The amplitude of spikes and down kicks, (Figs 4B,C), in the instantaneous battery voltage occurring at the inventor switching frequency, may be compared with known values to determine remaining energy. <IMAGE>

Title: Improvements in or relating to methods and apparatus for vacuum distillation
Inventor: OCKRENT CHARLES
IPC: B01D3/12
Filed: 1955-01-12
Abstract: <PICT:0782073/III/1> In a high-vacuum still the distilland is spread as a film over the distilling surface by means of a scraper actuated by a magnet which is itself moved by mechanical means outside the still. Fresh surfaces of the distilland are thereby continually exposed; and any charred material is removed from the distilling surface.  The latter may be in the form of a disc, a rectangular plate, or a cylindrical tube; and it may be made of aluminium, copper or brass, if necessary plated with silver, chromium or gold.  The distilling surface may be heated by electricity, steam or hot liquid circulation thermostatically controlled, or by infra-red radiation. The distilland removed from the distilling surface by the scraper may, if desired, be recirculated to the distilling surface; and by raising the temperature of this surface various fractions may be obtained.  The apparatus shown comprises a hollow cylindrical column 11 enclosed in an air-cooled tube 14 which is evacuated.  The interior of the column, which is at atmospheric pressure, contains an electric heating element 13. The distilland is introduced through tube 17 on to the outer surface of the column.  The column is surrounded by a close-fitting but freely-sliding steel ring 12 which is caused to reciprocate over the heated surface between points B and B1 by means of permanent magnet 15 which is itself reciprocated by an external mechanism.  The movement of the ring over the distilling surface results in an even film being obtained.  The distillate condenses on the interior of tube 14 and is collected in annular channel 18.  The residue falls from the column into funnel 19 and thence passes to a receiver.  A still having a horizontal plate as the distilling surface is also described.  A scraper, which may have flexible strips to follow any inequalities of the plate surface, is rotated over the upper surface of the plate by means of permanent magnets which are moved by a motor.
