Title: Toaster
IPC: A47J37/08
Filed: 1987-03-11
Abstract: An electrical toaster is provided with timing means which 
is initiated when a food product carrier is secured in an 
operative position adjacent a toasting element. The timing 
means normally releases the carrier from its operative 
position after a toasting interval. In the event of a 
malfunction, the timing means operates a cut-out to 
interrupt the supply of power to the toasting element 
within a predetermined period to prevent combustion or 
ignition of the food product. The latter period is longer 
than the normal toasting interval. The timing means may 
include first and second timing devices for respectively 
timing the toasting interval and the predetermined cut-out 
period. Alternatively the timing means provides respective 
outputs for controlling the toasting interval and the 
cut-out period.

Abstract: A stored program having a plurality of separately installable 
features, stored on a computer system is to be updated. An end user 
invokes an update program to update the stored program. The user selects 
one of a plurality of operating modes for the computer system and 
identifies a target drive and directory where the software program is 
stored. Thereafter, the user identifies a source drive and directory 
where a plurality of update files are stored. If a prompted mode of 
operation has been selected, the system copies the update files from the 
source drive and directory to the target drive and directory and then 
applies all of the updates to the respective features stored on the 
target drive in a sequential manner. If a full function mode of opera­
tion has been selected, the system copies the update files from the 
source drive and directory to the target drive and directory and then 
displays the highest numbered update stored on the target drive and 
directory for a selected installed feature. The user can apply the 
highest numbered update and all of the lower numbered updates associated 
with the selected feature or a subset of the updates in a sequential 
manner.
