Title: Method for editing character bit maps at small sizes using connected runs
Inventor: BYRON MICHAEL
IPC: G09G5/28
Filed: 1991-06-12
Abstract: ABSTRACT A method of displaying a character on a raster device wherein the character is described by means of one or more paths. The crosses where a path intersects horizontal pixel midlines are identified and paired in scan line order as cross pairs.  Runs of pixels are identified from the cross pairs.  Collisions are iden-tified between two runs of pixels and the repair operation is performed to remove the collision while maintaining the integrity of the character.  The most common repair operation is to move or delete one or more of the pixels involved in the collision.            D921 - Bit Map Edit                                   34

Abstract: ABSTRACT OF THE DISCLOSURE        A telephone set which may be readily changed from a desk unit to a wall mounted unit without tools and without removing and re-installing any receiver-retaining parts or components has a handset with a receiver portion and a transmitter portion and a base with a transmitter portion receiving depression and a receiver portion receiving depression.  An arm unit mounts within the receiver portion receiving depression.  The arm unit has a pair of spaced apart side arms joined at one end by a transverse member.  The arm unit has a pivotal mounting arrangement that enables the arm unit to move between a first position and a second position.  In the first position, the set is used as a desk unit with the side arms at the sides of the receiver portion receiving depression and the transverse member is at the end of the receiver portion receiving depression nearer the transmitter portion receiving depression.  In the second position the set is used as a wall unit with the side arms extending outwardly from the base.   The space between the side arms is adapted for receiving the receiver portion when in the desk position.  The side arms support the handset below the receiver portion when in the wall position.  The ends of the side arms remote from the transverse member each have an inturned flange portion to aid in retaining the handset in the wall unit position.

Title: Closure button/panel energy enhancement
Inventor: VERCILLO PETER A
IPC: B65D79/00
Filed: 1991-10-03
Abstract: This relates to a closure cap having an end panel which is equipped with a central button or panel area so as to cause deflection, either by way of a vacuum within an associated container or by mechanical action when a container is closed. Recently, there has been developed a desire for a louder popping noise when the closure is removed. Also there has been developed tamper indicating indicia elements to be actuated by the button or panel area to irreversibly indicate that a container has been opened even though the closure cap has been reapplied. A need for a greater stored energy in the button or panel area has been found and such additional stored energy is obtained by utilizing faceted areas or portions.
