Title: Electronically assisted engine starting means
Inventor: REMMERS GREGRY M
IPC: F02P15/12
Filed: 1987-05-05
Granted: 1992-03-03
Abstract: ELECTRONICALLY ASSISTED  ENGINE STARTING MEANS         Abstract of The Disclosure An improved engine ignition system for a marine engine  or the  like,  which provides reliable start-up capability and running protection.   The system detects the actual rotational speed of the engine and provides an electrical signal that is proportional to the measured speed,  and  selectively  advances  the  ignition  timing characteristic, and also controls overall engine speed to prevent engine damage that may be caused by an overspeed condition.    The  system  advances  the  ignition  timing characteristic  during  warm-up  until  a  predetermined temperature is achieved, and also advances the ignition timing characteristic  for a predetermined time period during initial running.  The system utilizes the power of the battery during start-up to supplement the power that is generated by the stator coil which normally supplies all of the necessary power for the control circuitry of the ignition system.

Title: Cereal products naturally sweetened with fructose
Inventor: MASELLI JOHN A
IPC: A23L7/104
Filed: 1988-09-27
Granted: 1995-12-05
Abstract: Breakfast  cereals  are  sweetened  by  treating  cereal grains or at least  one cereal grain fraction such as  bran, with enzymes comprising  glucoamylase and glucose  isomerase to  produce   fructose  while   retaining  cereal   particle discreteness  or  integrity.     Enzymatic  treatment   with alpha-amylase may be  initiated prior  to, during, or  after cooking.  The  enzymatically treated,  cooked cereal  grains are formed into breakfast cereal shapes and the enzymes  are inactivated to provide a  shelf-stable cereal product.   The cereal products exhibit a sweet, pleasing complex honey-like taste and  aroma.   Producing  fructose provides  a  greater level of sweetness for  a given amount of starch  conversion into low molecular weight reducing sugars such as mono-  and di-saccharides.  In  achieving a  given level of  sweetness, more  starch  or  high  molecular  weight  dextrins  may  be retained for their  matrix forming ability or for  improved machineability of  the enzymatically  treated cereal  grains into breakfast  cereal  shapes.    The  naturally  sweetened cereal products of the present invention may be in shredded, flaked, ground, or extruded form.

Abstract: ABSTRACT OF THE DISCLOSURE A handrail for transportation apparatus, such as escalators and moving walks, which includes an elongated, extruded elastomeric member having first and second wear strips fixed to inner surfaces of the elastomeric member for contacting a handrail guide.  Each wear strip has a substantially   U-shaped   cross-sectional   configuration, including a bight and spaced leg portions, and, in addition to providing low friction wear surfaces, the configuration aids the handrail in resisting derailment from a handrail guide.  At least one leg portion of each wear strip has a plurality of  spaced slots,  or  thin  webs,  which  extend inwardly from the end of the leg to facilitate flexing of the elastomeric body member while traversing curved por-tions  of  A handrail  guide.   In  another  embodiment,  a plurality of relatively short,  discrete wear strips  are spaced  apart to  collectively  define  an  elongated wear strip,  with the  spacings being selected to  function as flexibility imparting slots.

Abstract: ABSTRACT         A  safety  knife  comprises a handle formed with an  elongate   narrow  slot   which  extends  transversely completely  through  the  handle  from one lateral surface thereof to the other, and extends  lengthwise from  a slot mouth  in  an  outer  surface  of the handle to a location within the  handle.   The handle  is formed  in two halves which  are  clamped  together  by  bolts,  and  sandwiched between the two halves  is a  blade having  a cutting edge which extends  at an  acute angle  across the width of the slot at  a location  spaced inwardly  from its  mouth.  In use, string  or similar material to be cut is passed along the slot until it meets the cutting edge of the blade, and continued pressure  of the blade on the string then severs the string.  Since the cutting edge is  encased within the handle and  is spaced from the mouth of the slot, there is little or no risk  of the  user being  accidentally cut by the blade.

Abstract: ABSTRACT          A sensing arrangement is provided for bulk material conveying equipment such as pavers or the like, wherein the sensing arrangement comprises a non-contacting sensor fixedly mounted to the equipment, for sensing the distance between the level of the bulk material and the sensor.  The remote location of the sensing device from the bulk material, such as hot asphalt in a paving machine, reduces the requirements of the sensing device to withstand extreme environmental conditions.  The sensing device is thus no longer being subject to the heat of the asphalt or to abrasion from the material.
