Abstract: An infant bottle timer apparatus is set forth where an encircling indexed band is fixedly securable to an associated exterior surface of a baby bottle-type feeding implement. The timer apparatus includes a lowermost portion indexed consistent with the hours of the day and a pointer selectively manipulatable within an overlying integrally formed track for indication of a subsequent feeding timing event. The track includes a channel capturing a leaf spring. The leaf spring is secured to and cooperates with the pointer which is of a generally "H" shaped cross-sectional configuration. A first pair of legs of the "H" shaped pointer is ridable within the channel and frictionally securable within the channel in cooperation with the leaf spring. A further pair of legs of the "H" shaped pointer are oriented exteriorly of the channel for indication of a subsequent feeding event in cooperation with the indicator band.

Abstract: A technique of measuring very high temperatures by positioning a blackbody sensor in thermal communication with an environment or object whose temperature is to be measured, communicating infrared emissions having an energy level proportional to such temperature from the sensor to an infrared absorber positioned a distance away from the sensor where the ambient temperature is significantly reduced, and then optically measuring the temperature of the absorber by a technique that uses visible or near visible optical radiation, such as one using a luminescent sensor. The measured temperature of the absorber is proportional to that of the blackbody sensor.

Abstract: Apparatus for simultaneously applying two independent forces to the contact blades of a movable contact assembly. The contact assembly has three contact blades joined at the base. The circuit breaker mechanism exerts a closing force through a blade carrier to the center blade which in turn exerts a closing force on the outer main blades. To increase the contact force on the outside main blade contacts without increasing the contact force of the center blade contact and without changing the relative distances between the blade carrier and the main blade contacts and center blade contacts, a compression spring is positioned between each main blade and the blade carrier.

Abstract: A pointer for an indicating instrument is constructed of material transparent to light, the pointer having an elongated shape and a cross section having two inclined sides directed towards an apex, and a lower side opposite the apex and facing a face of the indicating instrument. The lower surface is provided with a layer of coloring, substantially opaque to the light, and giving a colored appearance to the pointer upon viewing the pointer by looking straight down upon the indicator face or at an angle thereto. The inclination of the pointer sides provides for respective refraction and total internal reflection to viewing rays of light which make visible the coloring.

Various embodiments of the invention encase the flexible clamp with soft rubber or a cloth material. In addition, the directional fingers may have a pointed end or may have raised letters indicating the exiting direction.

Abstract: Identification of work pieces such as wrenches by providing a unique color marking that permits a desired wrench to be selected from a group of wrenches by identifying the unique marking. The marking can be a color code provided by a single band of colored tape affixed to the work piece and unique for each different size of the work piece. In another color coding scheme a different color is assigned to each different digit of the numerical system. Two color bands can then represent a two digit numerator of a functional size and two additional color bands can represent the denominator so that any size from 0 to 98/99 can be indicated.
