A chair of the type used in theaters or the like includes a seat mounted to a standard by pivot mechanisms which bias the seat to a three-quarter fold position in which the seat is raised to permit row egress. The chair back is pivotally mounted for rotation about a horizontal axis located in the back area of an occupant. A link connects the specially formed seat frame to the lower part of the bac...

A television bulb is set forth which defines various structural relationships within the bulb construction to enable the manufacture of thin, lightweight TV tubes. The bulb is formed from strengthened glass systems such as laminated sheet glass or chemically strengthened glass, and includes a panel and a funnel having mating outwardly-extending peripheral flange portions which are sealed together....

PURPOSE:To obtain a lead accumulator excellent in a discharge voltage characteristic or in filling-up efficiency by a method wherein with regard to the lead accumulator using clad type electrode plates, electric energy generated in each part of the pole plates is taken out to the upper outer rib under relatively same resistance and likewise each part is uniformly filled up in case of the charging ...

A flowbox for a paper or board web-making machine is provided with at least one side wall movable along an axis at right angles to the direction of stock flow through the flowbox, whereby the width of the flowbox may be varied and the web deckled before it leaves the flowbox.

An electroacoustic transducer comprises a diaphragm (1), a magnet system (4) and a voice coil (3) arranged on a voice-coil former (2) in an air gap (5) of the magnet system. The movement is transmitted between the voice-coil former and the diaphragm via a lever mechanism comprising n lever devices (6) arranged at an angle relative to each other (n>/=2). A lever device (6) comprises a lever arm (9)...
