Abstract: The head band of a cap has a resilient member positioned around the rear of the cap with end portions of the resilient member secured to a frontal head band portion in the vicinity of the temples of the wearer of the cap. The end portions of the resilient member urge the frontal head band portion of the cap away from the forehead of the wearer and the frontal head band portion is formed in convex manner relative to the forehead of the wearer of the cap to provide a venturi-like opening between the frontal head band portion and the forehead for enhancing evaporation of perspiration from the forehead of the wearer of the cap.

Abstract: A vehicle safety or caution sign is attached to the side of a vehicle. The sign is held by an elongated member which is coupled by a first pivot to a mounting member that attaches to the vehicle. The first pivot enables the sign to be swung in a fore and aft direction relative to and toward and from the vehicle. The sign has a bearing member secured thereto and which operates as a second pivot and is coupled with the elongated member to enable the sign to hang in a generally vertical position when the vehicle is moving at a slow speed or is stopped, and to enable swinging of the sign to a generally horizontal position when the vehicle is moving in excess of a predetermined speed.

Abstract: A U-shaped lock fits around the shank of the door knob assembly and the two legs of the lock are received by an extended strike plate in a locked condition. The door lock is retained around the shank by keeper means on at least one of the legs of the lock.

Abstract: An impact printer is provided which is capable of printing at either 10 characters per inch (standard pitch) or 15 characters per inch (compressed pitch) by changing the type character carrying member, such type carring member including multiple font character sets thereon. The type character carrying members or bands include timing marks thereon for detecting or sensing the type band (standard or compressed pitch), the type character font set, and for tracking the type characters on the band. The printer also includes time shared hammer means which are movable or shifted a precise distance of 1/10 inch for a standard pitch band or a precise distance of 1/15 inch for a compressed pitch band, such movement being operable by control mechanism responsive to pulses derived from the timing marks relative to the horizontal position mechanism and the type band on the printer (standard or compressed pitch).

Abstract: A code reader, in the form of a photoelectric sensing device, is slidable across a coded disc which disc includes a first circle of apertures at one diameter designating a code channel for advancing record media, for example, at a spacing of six lines per inch and a second circle of apertures at another diameter designating a code channel for advancing the record media at a spacing of eight lines per inch. A positive locking detent is associated with the code reader for maintaining the desired position thereof for the selected code channel and line spacing.

Abstract: A welding fixture includes members supporting the ends of a print band and spaced to permit welding of the ends of the band with a laser beam. The edges of the band on either side of the weld joint are held parallel by means of at least two alignment pins on either side of the weld with the pins forming one terminal of a plurality of switches in circuitry to indicate proper alignment of the band prior to welding. One support member of the fixture is pivotable or tiltable to enable the ends of the band to be made square prior to welding.
