Title: Handling glass sheets during shaping  and cooling
Inventor: FRANK ROBERT G
IPC: C03B35/16
Filed: 1979-09-26
Granted: 1982-07-06
Abstract: Abstract This invention relates to improvements in handling glass sheets during shaping and cooling.  Each glass sheet in turn is heated to its deformation temperature and conveyed into a glass shaping station.  The glass is lifted into engagement with an upper vacuum shaping mold while hot and held against the vacuum shaping mold by vacuum as the glass lifting mechanism retracts downward.  A transfer and tempering ring-like member having stop means upstream of an outline supporting surface conforming to and slightly inside the periphery of the bent glass sheet is brought into a position where its stop means are slightly misaligned upstream of the trailing edge of the glass sheet.  The vacuum on the upper mold is released to deposit the shaped glass sheet on the ring-like member.  The latter starts suddenly to displace the bent glass sheet into proper alignment with the ring-like member for movement into a cooling station where the shaped glass sheet is quenched as rapidly as possible to harden the glass surface and then transferred to an unloading conveyor at a transfer station.  The ring-like member starts its rapid return from the transfer station to the shaping station before the shaped glass sheet is transferred to a position completely downstream of the ring-like member.

Abstract: ABSTRACT OF THE DISCLOSURE     For continuous production of ethanol by fermenta-tion, fermenting liquor is fed directly from a fermentor to a simple evaporator unit where a vacuum is maintained and where the liquor is separated into a first vapor flow en-riched in ethanol, which is processed to the desired ethanol quality, and a yeast-containing bottom flow.  Of the latter flow, part is recirculated to the fermentor while the rest is separated into a yeast concentrate flow, which is recir-culated to the fermentor, and a yeast-free flow which is fed to a stripping unit.  The second vapor flow, enriched in ethanol, which is thus obtained from the stripping unit can be fed to the simple evaporator unit directly or indirectly.          The method is especially advantageous if the substrate is made by enzymatic break-down of cellulose or starch, as the enzymes in this case are not subjected to excessive tempera-tures but can be recovered.

Abstract: ABSTRACT OF THE DISCLOSURE        A tachometer signal provides input to first and second parallel connected channels, each of the channels comprising in series operational amplifier, threshold detector, and counting devices.  A comparator checks that the same count is registered by the counters of both channels.  Each of the threshold detectors is biased to require a minimum amplitude over and under tachometer pulse input in order to deliver an output to the pulse counter of the associated channel.  Attenuating circuits act on the inputs of the operational amplifiers of both channels during predetermined intervals to check that the amplitude of the tachometer pulses is sufficient to be counted by the tachometer counters.  Dynamic checking circuits are provided to check the integrity of the attenutating system.
