Patent CA-2003750-C (CA)
Title: Automatically activated commercial message timer
Inventor: WINE CHARLES MARTIN
IPC: H04H60/31
Filed: 1989-11-23
Granted: 2001-01-16
Abstract: A commercial message timer stores data indicative of a first tuned station in response to a channel change command and begins repeatedly timing a predetermined time period. Upon each expiration of the time period, the user is reminded that the commercial message on the first tuned station may be over. In this way a user can avoid a commercial message on a first channel by setting the timer and scanning through other channels, and yet be reminded to return (e.g. by use of a PC (previous-channel) key) to the first channel at the end of a time period substantially equal to that of a typical commercial message. In another embodiment employing a videocassette recorder (VCR) the commercial timer is activated upon pressing the PAUSE key of the VCR so that the user may avoid recording the commercial message on videotape.

Granted: 1996-05-14
Abstract: An apparatus for heat treating contaminated particulate material and more particularly, an appar-atus for reclaiming foundry sand.  The apparatus includes a heated, inclined rotary drum and an auger projects into the upstream end of the drum and serves to feed material to the drum.  The auger includes a spiral flight carried by a hollow shaft and a blower is connected to the outer end of the hollow shaft so that air is supplied through the shaft into the drum.  A seal is provided between the non-rotating auger housing and the drum, and the seal includes an annular bearing plate mounted on the end of the drum while a sealing ring is connected to the auger housing and is biased against the plate to provide a seal.
