Title: Simulated fireplace assembly
Inventor: HESS KRISTOFFER
IPC: F24C7/00
Filed: 1999-02-19
Granted: 2005-09-13
Abstract: A device is provided for enhancing the realistic appearance of flames produced by a simulated fireplace (gas or electric) by providing additional ambient lighting effects in response to sensed light intensity within the fireplace. The device includes a photosensor, a control circuit, and display lighting. The photosensor senses the level of light intensity produced by a simulated flame source and changes its resistive value accordingly. The control circuit has circuit parameters which uses the resistive value of the photosensor to determine whether to apply operational power to the display lighting. The display lighting consists of at least one lamp positioned above the simulated fuel bed. When simulated fireplace is operational, the display lighting of the device produces a "flickering" effect that is synchronized with the changes in light intensity occurring within the fireplace. The resulting ambient lighting effect realistically mimics the changes in light intensity that normally occur above the flames of a real wood burning fireplace.

Abstract: A tracking assembly (10) for tracking belts (12, 52) and webs comprises a support frame (20) which is adapted to be mounted below a travelling belt or web. A straight or angled support shaft (30) is pivotal ly mounted at its centre via a post (32) which is rotatable within bush (26, 56) on the support frame. A selected arc of rotation of the post within the bush (26, 56) is determined by an adjustable limit stop arrangement which can take the form of a pair of grub screws. A roller is mounted onto each end of the shaft (30). The two rollers (36, 50) have tapered ends (38, 54). When the belt or web travels off centre it will come into contact with the tapered end of the roller on the side to which the belt has moved. This will cause the shaft to pivot about a vertical axis of the post (32) and thereby steer the belt back to a central position.

Abstract: L'invention concerne un procédé de manutention mécanique de matériaux discrets qui consiste à charger une base de palette à plan de chargement qui comporte un châssis entourant des volets s'ouvrant vers le bas, à transporter la base chargée sur le lieu requis tout en soutenant les volets sur les fourches du chariot élévateur, à poser le châssis sur le lieu requis sur des éléments convenablement espacés, et à abaisser les fourches pour faire en sorte que les volets s'ouvrent de manière à permettre un déchargement par gravité. Deux volets de ce type peuvent être employés, mais dans un mode de réalisation préféré, on utilise deux volets inférieurs ayant un angle d'ouverture limité, et deux volets supérieurs situés à distance réduite au-dessus des volets inférieurs, qui s'articulent à angle droit par rapport aux volets inférieurs et qui ont une forme si effilée que leur angle d'ouverture est limité par la position ouverte des volets inférieurs. Dans un autre mode de réalisation, l'angle d'ouverture est limité par des taquets liés aux éléments espacés sur lesquels repose le châssis de la base de palette à décharger. Ainsi, les deux paires de volets s'ouvrent de manière à former une goulotte de déchargement de matériau en forme d'entonnoir.
