Abstract: ABSTRACT OF THE DISCLOSURE            A device for accumulating and displaying nutri-tional values has first and second display units each of which displays carbohydrate, protein, fat and calorie values.  Food items to be consumed are keyed into the device on a keyboard and the values assigned by the device to those items are displayed on the first display unit.  When an entry key is pressed, the values for the newly entered items are added to the values of items previously entered for the day and the new totals are displayed in the first display unit.  A desired daily calorie limit is selected by a selector button and the second display unit shows this limit and also the values assigned by a memory to that limit.  If the calorie total in the first display unit exceeds the calorie limit dis-played in the second display unit, an alarm is activated.

Abstract: OPTICS CONTAMINATION PREVENTION UTILIZING     A COANDA AIR DEFLECTION SYSTEM              Abstract of the Disclosure In a document copier machine an almost completely enclosed optics module is provided to keep the optical components isolated from the remainder of the machine and thereby minimize contaminantion of the optical components.  The described module has three large openings.  One of these openings is an air inlet which opens to the exterior of the machine for bringing cooling air to a fan located inside the module.  The second opening is an air outlet to allow the optics cooling air to exit.  The third opening is critical to contamination and is an aperture which opens to the interior of the machine to allow illumination to pass from the optics module to a photoreceptive surface.  In order to prevent air flow into the module through the aperture, louvers are situated at the fan to direct an airstream onto a first Coanda surface to move air toward the aperture.  Light shields provided near the aperture to guard against stray light also provide an additional non-contamination function by capturing the airstream from the first Coanda surface and directing the airstream to the aperture.  One of the shields can also act as a second Coanda surface in the transfer of air to the aperture.  In that manner a positive flow of air out of the aperture is provided, thus preventing contami-nation of the optics module.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for cutting pattern pieces from sheet material with an automatically controlled cutting machine utilizes special control techniques for guiding a reciprocating cutting blade accurately along a desired cutting path defined by the pattern piece peripheries.  The cutting machine includes a control computer which also serves as a data processor for generating machine command signals and controlling cutting blade movements.  The controller has memory units which contain standard cutting programs and optional programs.  From a program selector panel, the cutting machine operator can select optional programs which modify the standard programs in a manner most suitably adapted to cause the cutting blade to follow the cutting path in the sheet material more accurately.  The optional programs vary the feed rate or stroking speed, introduce yaw signals to control blade orientation along the cutting path, or perform other control functions.

Abstract: ABSTRACT OF THE DISCLOSURE         A broach system comprises a plurality of disposable carbide inserts which are precisely positioned and secured within the slot of a branch holder.  An elongated side clamp having a shaped contact surface is located along one side of the slot on a sloping surface of the holder.  The side clamp is tightened camming the inserts against the side and bottom locating surfaces of the holder.  A front clamp is also mounted to the holder and tightened which forced the inserts against a rear stop on the holder.  Several holders may be readily assembled in series to perform a complete broaching operation such as dovetail forms in super high strength materials used in gas turbine engines.  The broach system replaces the conventional broach design of brazed construction wherein carbide blanks are permanently fastened to a steel holder and it is an improvement over conventional mechanically held inserts.  As advantages, the system reduces down time and set-up time.  Also, there is lower risk of insert breakage and a resultant increase in tool life.
