Patent number: 4388687Abstract: A memory unit having a multiplicity of storage locations for the temporary storage of series of groups of data signals. When the data groups are being stored in a memory location, index signals are developed that not only identify the location of the stored signal group, but when applied to the memory unit cause the data group to be withdrawn from the memory unit. The memory unit is comprised of a first addressable multiplicity of storage locations; a second addressable multiplicity of storage locations, the contents of the second multiplicity of storage locations adapted for addressing the first multiplicity of storage locations, a counter for addressing the second multiplicity of storage locations; and control logic for controlling the counter and entry and withdrawal of data signals in the first and second multiplicity of storage locations.Type: GrantFiled: January 5, 1981Date of Patent: June 14, 1983Assignee: Honeywell Information Systems Inc.Inventors: Jerome J. Twibell, Robert J. Johnston

Patent number: 4378944Abstract: A game apparatus including a stand having a generally horizontal platform connected to a generally upright column. The platform has a plurality of distinct sides with point value indicia associated with each of these sides. A target object is placeable on the platform and is connected to the platform by tether means. A projectile is thrown at the target object from a remote distance with the object of knocking the target object from the platform over one of said sides. The points awarded the player participant throwing the projectile depends on which of the sides of the target is knocked over.Type: GrantFiled: June 11, 1981Date of Patent: April 5, 1983Inventor: Robert J. Johnston
