Abstract: A multi-piece hammer for use in a reducing machine. The multi-piece hammer includes a base to be mounted to the reducing machine, a replaceable tip to be mounted to the base and to impact the material to be reduced, and a retainer to secure the replaceable tip to the base. The replaceable tip has a cavity with a single rail or groove that corresponds to a single groove or rail on the base.

Abstract: This invention provides a smart directory manager for deleting directory entries. The smart directory manager includes a directory memory, user interface devices and a directory management device. The directory management device generates a recommended delete-directory-entry of the directory memory and deletes the recommended delete-directory-entry from the directory memory when a delete instruction is received from a user. The directory management device generates the recommended delete-directory-entry by comparing information of each directory entry contained in the directory memory based on a predetermined delete strategy. The directory entry having the information that best satisfies the predetermined delete strategy is selected as the recommended delete-directory-entry.

Abstract: The two-pass directory entry device includes a directory memory, a user interface device and a directory entry controller. The directory entry controller, in a first-pass, stores into the directory memory at least one name received from a user through the user interface device. In a second-pass, the directory entry controller stores at least one number received from the user through the user interface device. The directory entry controller recalls the at least one name stored in the directory memory, outputs the recalled at least one name to the user and associates the at least one number received in the second-pass with the at least one name received in the first-pass.

Abstract: The invention provides an account number dialing device for a telephone station for calling a remote party by dialing an account number and a telephone number in response to a plurality of inputs received from a user. The account number dialing device includes a user interface device, a directory memory and a controller. The controller is coupled to the directory memory and the user interface device. The controller forms a number using a plurality of numbers fetched from the directory memory in response to the plurality of inputs received from the user through the user interface device and files the number. Each of the plurality of numbers is fetched from the directory memory in response to one of the plurality of inputs from the user.

Abstract: This invention relates to an apparatus for dispensing cotton rolls. More particularly, this invention relates to an apparatus which may be supported on a work table, credenza, sideboard or the like in use in an operating room such as a dental operatory for readily supplying users such as dentists, surgeons, and assistants with absorbtive cotton rolls. The dispenser has a base which defines a delivery chute portion having horizontally spaced apart, upwardly directed surfaces, to which rolls are dispensed from a reservoir formed in part by a pair of planar lower wall portions, each lying on a plane parallel to said axis of rotation and diverging upwardly from a juncture line below the location of the axis of rotation of a dispensing wheel, and which direct rolls to the dispensing wheel which is mounted for rotation about a generally horizontal axis spaced above the delivery chute.
