Abstract: Methods and systems for graphically depicting gum tissue and teeth for illustrating gingival health and plaque reduction. The relative risk as one type of statistical methods for comparing two treatments of different therapeutic agents for gingivitis and plaque are displayed. The upper and lower sets of teeth are represented in rows or groups of teeth separated by rows of boxes which depict the result of various treatments by various therapeutic agents.

Abstract: Methods and apparatus for changing the collet assembly or armature-holding assembly of an armature winding machine are provided. The apparatus permits the collet assembly and selected sleeves of the armature-holding assembly to rotate about a longitudinal axis, while preventing undesirable translation along the axis. The apparatus permits translation of at least one other sleeve. The collet assembly may be removed from the armature-holding assembly to accommodate armature shafts of various diameters. Alternatively, the entire armature-holding assembly may be removed and replaced as a single unit, to accommodate commutators of various diameters. The change-over process can be automated.

Abstract: Method and Apparatus for fusing electrical conductors to electric motor parts including a movable contact sensor (45) or optical sensor for determining the perpendicular distance of a reference plane of an electric motor part to be fused from a fusing apparatus and using this measured distance to control the fusing operation.

Abstract: A wire gripper which facilitates insertion of a wire and which retains wires of varying thickness. The wire gripper includes a first member biased towards a second member so that the first and second members are tangent to one another until a wire is inserted. An inserted wire rests on a receiving member beyond the point of tangency of the two members. The two members are resiliently urged together to prevent the inserted wire from leaving the wire receiving member.

Abstract: Apparatus for fusing electric motor parts (e.g., fusing electric motor armature coil leads to the commutator of the armature) includes positive control of the elements which move to perform the fusing cycle so that the fusing cycle stroke can begin at any desired location. This facilitates shortening the stroke and making it constant despite changes or deviations in the workpieces being fused. It also facilitates withdrawal of the fusing head to a location which is more remote from the workpiece when the fusing electrode is to be changed due to wear. In fusing machines having a rotating turret which carries several fusing electrodes, the mass of the moving parts is reduced by mounting the actuator which reciprocates the turret on the frame of the machine, and by deriving the motion required to rotate the turret from the reciprocation rather than from a separate actuator.

Abstract: Multiple electric motor parts are processed simultaneously by apparatus which removes the parts from a conveyor (on which the parts are side by side in a substantially horizontal plane), repositions the parts so that they are vertically above one another, processes the parts while they are thus repositioned, and then returns the parts to the conveyor in their original side by side relationship in a horizontal plane. In addition, a gripper apparatus for electric motor components that can be used to grip components of different sizes, and that can rotationally index electric motor components of different sizes, is provided. The gripper apparatus has two oppositely facing gripper arms with complementary V-shaped faces sized to accommodate a range of sizes of components. The arms are moved together in unison to center and grip the component. After the component has been gripped, an indexing pawl rotates the component.

The arms are moved together in unison to center and grip the component. After the component has been gripped, an indexing pawl rotates the component. A tooth is urged against the component and stops the rotation when it enters a depression or slot in the component, indicating that the desired angular position has been reached.

Abstract: A pallet system for supporting a workpiece (such as an electric motor stator or rotor) during processing of the workpiece includes a pallet member on which a workpiece holder can be removably placed. The workpiece holder may have multiple workpiece-engaging sites, each of which is adapted to hold a differently configured workpiece, and multiple pallet-engaging sites, each of which is associated with a respective one of the workpiece-engaging sites and any one of which can be used to engage the pallet so that the workpiece holder can hold a workpiece of the appropriate configuration at the associated workpiece-engaging site. Methods and apparatus for storing and manipulating the workpiece holders are also disclosed.

Abstract: The axial end portions of the insulating members which are used to line the longitudinal channels formed between circumferentially adjacent, radially inwardly projecting poles in a stator (e.g., an electric motor stator) are protected from damage by the wire being wound by providing terminal boards at each axial end of the stator having portions which overhang the axial ends of the insulating members. Temporary wire grippers may also or alternatively be mounted on the axial ends of the stator (e.g., on the above-mentioned terminal boards) for temporarily holding the leads of the stator coils prior to permanent termination of those leads on permanent terminals on the terminal boards.

Abstract: A multiple unit carton composed of a plurality of individual cartons joined by carrier means. Each carton holds at least one pair of cigarette packs aligned with their long walls abutting, and their short walls coplanar. The multiple unit carton is preferably dimensioned to resemble a ten-pack cigarette carton so that the multiple unit carton may be passed through commercially available tax-stamping machinery, which is commonly designed to process ten-pack cigarette cartons. The individual cartons are joined with adhesive bearing carrier means such that the cartons remain securely connected when being passed through tax-stamping machinery.

Abstract: A dual cigarette carton formed from two substantially identical single cigarette cartons. A label bearing indicia encoded for the automatic pricing of the dual carton is placed across adjacent coplanar walls of the two single cartons. The indicia are positioned such that they are rendered unreadable by automatic equipment when the two single cartons are separated for individual sale. Each single carton further includes indicia encoded for the automatic pricing of a single carton, the indicia being positioned such that they are not readily visible when the single cartons are connected to form a dual carton.

Abstract: An outer wrapper for a container which includes an integral tear tape. The tear tape is formed by cutting two sets of score lines extending partially through the thickness of the wrapper material. The tear tape can be patterned to conform to the parting line along which the container opens, including oblique segments, thus allowing the container to be opened without interference from the parts of the wrapper which remain in contact with the container subsequent to removal of the tear tape.

Abstract: A dual carton formed from two cartons each having at least one pair of opposed top flaps. One carton has an extended top flap which extends over the other carton when the cartons are positioned adjacent one another such that the extended top flap may be secured to the top flaps of the other carton to thereby join the two cartons to form a dual carton. The extended portion of the extended top flap is joined to the remainder of the extended top flap along a weakened line to facilitate later separation of the two joined cartons. The dual carton may be a cigarette carton of dimensions compatible with tax-stamping machinery and temporarily sealed in such a manner as to facilitate the opening and later resealing of the carton for tax-stamping purposes.

Abstract: A cigarette carton formed from a blank in which the front and rear long walls of the carton are joined along a side wall instead of along a top or bottom wall. The carton thus has two sets of closure flaps, one set along the top end and another set along the bottom end. At least one set of closure flaps is a set of lap flaps, which are easily opened by a tax-stamping machine and easily closed by a machine. Preferably the other set of closure flaps is a tuck-in flap which is easily openable and reclosable by a consumer. Also disclosed is a multiple unit carton formed by applying adhesive bearing carrier means across top and bottom walls of the adjoining cartons. The multiple unit carton may be separated by a retailer or consumer for purchase of the individual component cartons.

Abstract: A box-like cigarette pack has an innerframe which initially extends upward into what is normally a cutout in the front of the innerframe. This extension may then continue over the top of the cigarettes in the pack. The innerframe is weakened along the line which normally defines the cutout. When the consumer first opens the pack, he or she can remove the innerframe extension by tearing or separating along this line of weakening. Thereafter, the pack is like a normal pack. Additional information can be printed on the removable portion or portions of the innerframe. If provided, the portion which initially extends over the cigarette tops is a convenient size for use as a coupon or the like.
