Abstract: According to an aspect of the disclosure, a glass manufacturing system includes a hot-end subsystem, including: a submerged combustion melter that melts feedstock to produce molten glass; a stiller that receives the molten glass from the submerged combustion melter and that includes a stilling tank to still the molten glass and that is configured to control outflow of the stilled molten glass to effectively decouple viscosity of the molten glass from the flow rate of the molten glass and thereby control finer molten glass levels; and a finer that is mechanically decoupled from the stiller, and that receives and fines the stilled molten glass to produce fined molten glass. Many other aspects of the system are also disclosed and claimed.

Abstract: A loudspeaker system comprises a flexible paper or plastics diaphragm 1 for displacing a quantity of a transmitting medium to generate sound, waveform-sampling circuitry for supplying a series of sample drive signals of varying amplitude indicative of the amplitudes of an electrical input signal having an audio waveform

Abstract: Cable locking and sealing device which has a body member to which one end of a cable can be attached with the other end free to pass through a hasp or other device to be sealed or locked and in which the free end can then be inserted into the body member and can be freely moved in a first direction into the body member but which is clamped so that it cannot be removed from the body member in a second direction. Within the body member there is provided an inclined ramp at a small angle formed with a plurality of gear teeth and a locking gear formed with gear teeth which mate with the gear teeth on the rack and is movable along the ramp so as to lock the second end of the cable to the body member when force is exerted on it to remove it from the body member.
