Abstract: Drafting template adapted to be juxtaposed on a drawing sheet characterized by a plurality of like spaced lands, in a grid or comb configuration, across which a marking implement may be moved, forming marks on the drawing between the lands and leaving voids or spaces therebeneath. Templates for straight and circular broken lines and broken lines of other curvatures are disclosed.

Abstract: Tempered water supply system for a domestic basin, such as a bathroom lavatory, tub or shower, or a kitchen sink, characterized by an adjustable temperature mixing valve for hot and cold water, a supply valve including a hydraulic motor for controlling flow of tempered water from the mixing valve to an outlet such as a spout, and a pair of manual control valves for operating the motor. The control valves, and a manual control for the mixing valve, may be disposed at any desired positions on or relative to the basin. One control valve gradually moves the supply valve toward open position and the other similarly moves it toward closed position, which may be effected by continuous actuation or repeated incremental actuations, whereby actuation of one or the other increases or decreases outlet flow.

Abstract: Music box of the rotatable drum type with removable reed actuating pins which may be selectively disposed for playing various compositions, characterized by a drum having a peripheral surface without apertures therein and an envelope or sleeve surrounding same containing the apertures for retaining the pins, the envelope being injection moulded of plastic material, the apertures being non-circular, such as square, and the pins being cylindrical and of uniform diameter at all sections thereof.

Abstract: The present disclosure is directed to a hot stamping machine with a rotatable head for imprinting information on each individual frame of a roll of negatives or transparencies used in aerial photography whereby the printing head may be rotated to imprint on either side of individual negatives. The hot stamping machine has a static member and a movable member which is pivotally connected thereto for horizontal rotation about a vertical pivot. This rotatable head makes it possible to imprint on either the top or bottom of individual frames of a negative or transparency being fed through a machine and have the imprint read correctly. In addition, individual type holder blocks can be arranged in any desired position, and can be rotated so that the information contained on each type holder block will be imprinted or not, as may be desired. Finally, a provision is made for easily adjusting the pressure on either side of the imprinting head so as to ensure optimum imprinting with a minimum embossing of the film.

Abstract: A hand manipulated electrically heated stylus tool for transferring insignia to an article from a ribbon or sheet having a coating on one face thereof subject to release and transfer to an article to be printed which operates on a 115 volt power supply without use of a voltage reducing transformer or temperature control means. The tool includes an aluminum mandrel with a surrounding sleeve of heat shrinkable Teflon on which a heating element of high resistance insulated wire is wound so that the sleeve provides back-up insulation between the wire and mandrel. The mandrel is provided with a bore which receives the tip portion of a conventional ball point pen, thus forming a heated stylus. The heated stylus assembly is disposed within a hollow frusto-conical support and is secured therein by a hardenable mixture forming heat insulation between the assembly and the support.
