Abstract: A method and system of electronic image storage and display wherein the display is viewed on a raster scan TV display and the incoming signal comprises a sequence of scan lines whose line rate is lower than that of the horizontal TV line rate and is an integer submultiple, preferably even, thereof. The incoming signal is stored in the memory of a scan converter and the stored image is scanned and displayed on a conventional television raster scan display.The scan converter mode is alternated between read and write such that the writing is carried out during the time required to scan one horizontal TV line in the field and the reading is carried out during the time required to scan the next horizontal TV line in the field to thereby write and read during alternate horizontal TV lines.To produce a spatially uniform raster, the horizontal TV lines of succeeding TV fields are offset by one line from the horizontal TV lines of the preceding field.

Abstract: A hand-held label marking device prints selected bar code character information on labels by scribing selected code bars upon one area of a moving label juxtaposed with a printing medium and prints corresponding alpha-numeric character information upon another area of the label by impacting the label and printing medium against selected print elements, thereby establishing a standard symbol, such as that currently prescribed in the United States by the Universal Product Code. Further alpha-numeric information is printed upon a further area of the label by a reciprocating printing mechanism in the same device to provide consumer-readable price information. A compact arrangement of component parts enables the printing of a full range of bar code character information in accordance with a compact symbol standard such as the zero-suppression symbol standard of the Universal Product Code, together with the corresponding alpha-numeric character information.

Abstract: A golf game in which the player strikes a golf ball into a scoring field having a plurality of scoring zones and including a board having a representation of a golf course with a prescribed number of spaces between the tee and the cup of each hole. A movable playing piece represents a player's position on the course and is moved in response to the position of the struck ball on the scoring field to a space on the golf hole being played. Certain spaces are provided with specially marked indicia of two types for the selection of an instruction card from the designated stack of such cards associated with the particular specially marked space to further determine the movement of the player's playing piece.

Abstract: A drill bushing or similar article, such as a pump bushing having a hardened body of steel and a thin inner coating of tungsten carbide distributed throughout a matrix of nickel chrome which provides a metallurgical bond to the steel body and a metallic bond to the particles of tungsten carbide. The drill bushing or similar article will have the wear characteristic of the solid tungsten carbide article, but would retain the coefficient of expansion characterisic of steel with the steel body eliminating the brittleness experienced in solid tungsten carbide articles.

Abstract: A pair of orthogonal drive shafts carry cams which are coupled to a platform for orbital movement of the platform. The platform supports a workpiece below an electrode in an electrical discharge machining operation. The cams are cylindrical segments which extend axially at an acute angle to their respective drive shafts so as to present a changing throw along the axial extent of the cams and the coupling means is selectively adjustable along the axial extent of the cams to enable selection of the amplitude of the orbit. In another embodiment, a single drive shaft carries cams each having a throw extending perpendicular to the drive shaft and a further cam having a throw parallel to the drive shaft. The cams are coupled to a platform for orbital movement of the platform and have changing throws in the respective directions of the throws to enable selection of the amplitude of the orbit.

Abstract: In an apparatus for printing and dispensing labels carried in a label ribbon of indeterminate length, a hand lever is held in a rest position by a return spring and a printing device is coupled with the hand lever for movement toward a label, located on a printing table, upon depression of the hand lever and away from the printing table upon release of the hand lever. A transport mechanism is coupled with the hand lever for advancing the label ribbon by a distance equal to the label spacing on the ribbon each time the hand lever is actuated. A printing device is carried at the free end of a further lever movable in the same plane as the hand lever and normally held stationary by a pawl, the other end of the further lever being coupled with the hand lever through a further spring extending between the hand lever and the further lever.

Abstract: A game board has a system of courts where the outcome of lawsuits are determined and a continuous playing path around its edge. Chance devices direct movements of game pieces along the path, and indications on the path direct selection of cards relating to lawsuits.Each player has the opportunity as determined by the chance devices of claiming a specific lawsuit as his own and thereby becomes the plaintiff of that lawsuit. Another player may become the defendant of that specific lawsuit by a determination of the chance devices. The outcome of different lawsuits and their penalties are determined by a system of courts, required legal fees, use of an expert witness, and operation of the chance devices.
