Title: Method and apparatus for bending glass sheets
Inventor: FLAUGHER JEFFREY R
IPC: C03B23/03
Filed: 1992-11-25
Abstract: A method of and apparatus for establishing a predetermined thermal profile in a glass sheet immediately prior to press bending outside the heating furnance (12). The press bending members (26, 27) are provided with arrays of heating elements (70, 76) that are individually or zone regulated to assist in establishing an optimum temperature profile in the glass sheet conducive to proper bending. The temperature profile established in the heated sheet by the arrays of heating elements (70, 76) is coordinated with that established in the furnace (12) and subsequently, modified by heat dissipation as the glass sheet advances to the bending station (13) to achieve the proper bending temperature. The heating elements (70, 76), can also be utilized to create a temperature profile in a glass sheet generally higher than that originally established in the furnace (12). The sheet can be held in contact with one or both of the heated press members (26, 27) for a brief period of time after bending to slow the cooling rate of the sheet and increase the edge strength of the marginal edge area thereof.

Title: Twist tie ribbon feed, cut and tie apparatus and method of same
Inventor: PARKER ALEXANDER L
IPC: B65B51/08
Filed: 1993-09-21
Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus  for advancing a plurality of different predetermined lengths of twist tie ribbon is disclosed.   The apparatus includes a guide for guiding the ribbon along a feed path and a pair of opposed rollers for displacing the twist tie ribbon therebetween.   A  first  of the  rollers has  first  and  second circumferential portions and is displacable toward and away from the  second roller.   The  second  of the  rollers  has  a  first circumferential   portion   in   registration   with   the   first circumferential portion of the first roller and carries a plurality of biasing segments.  At least all but one of the biasing segments are slidably mounted on the second roller.  The biasing segments are slidable between a first position at which the biasing segments do not contact the second peripheral portion of the first roller, and a second position, wherein the biasing segments contact the first roller and displaces the first roller out of engagement with the tie ribbon, so that the tie ribbon is not displaced by the pair of  opposed  rollers.     The  advancing  apparatus  is  readily integratable into a twist tie machine that is capable of wrapping a plurality of different sized objects.  The predetermined lengths of ribbon are delivered to an operating position, at which they move a slide which mechanically displaces a hoop to bring the free end of the ribbon to an interior region thereof.  In response to the displacement of the slide, the length of ribbon is cut-off and twisted.

Title: Motor-driven, spring-returned rotary actuator
Inventor: HIGHTOWER PETER C
IPC: F24F13/14
Filed: 1994-02-01
Abstract: An electric motor acts through a gear train to rotate an output shaft in one direction while a torsion spring rotates the shaft in the opposite direction when the motor is de-energized. When the output shaft stops abruptly at a limit position after being rotated by the spring, a lost-motion drive connection permits the output gear of the drive train to rotate relative to the shaft in order to dissipate kinetic energy through the gear train and to avoid impact loading of the gear train and the motor.

IPC: F02P9/00
Filed: 1992-08-21
Abstract: An ignition system for hydrocarbon based fuels employing two energy sources ( 10, 16), one to create a spark, and the other to sustain the spark. The ignition system is based in pan on the principle of a strobe light circuit. The system increases ignition efficiency by increasing the power dissipated at a spark gap (14), particularly when used in conjunction with a surface gap spark plug. Maximum power transfer is achieved via impedance matching between a transformer (12) of the ignition system to the surface gap spark plug. The circuit is particularly appropriate for igniting extremely lean mixtures, highly diluted mixtures, and alternative fuels.
