Abstract: A dental hygiene preparation of very low toxicity, but with good remineralization properties and effectiveness in removing food particles and plaques from the tooth surfaces is particularly indicated for use by elderly patients and those with compromised immune systems. The preparation uses a nonfermentable sweetener in lieu of Sodium Fluoride, Sodium Monofluorophasphate or Stannous Fluoride as a caries-preventive agent in combination with Potassium Citrate and Disodium Edetate.

Abstract: Heatsinks for microcircuit packages are formed by first mold-pressing a composite powder of free-flowing spray-dried particles of copper and at least one other denser material such as tungsten and/or molybdenum breakably agglutinated in nodules grouping sub-nodules of surface alloyed pairs of particles of each metal, the proportions of which are adjusted to match the thermal expansion characteristics of the microcircuit material. The pressed compacts are then heated in a sintering furnace at 1090.degree. C. to 1150.degree. C. in order to effect an homogeneous distribution of the melting copper throughout the structure. The process results in a readily usable component having good thermal conductivity and matched thermal expansion that requires no further machining.

Abstract: A circuit for automatically addressing and activating redundant circuits on an integrated circuit chip during testing, thereby improving efficient use of the space available for fuses and fuse pads. The circuit uses an integral number of fuses, whose blown and unblown combination represents 2**n possible states. Each state represents the address of a particular circuit or set of circuits gone bad on the chip which needs to be replaced. By employing an incrementor, the logical address representing the circuit or set of circuits physically adjacent to the bad circuit is also replaced. More sophisticated incrementors may be used to address more than one adjacent circuit or sets of circuits having a non-incremental address.

Abstract: A nursing bottle support for freeing the hands of a person carrying an infant while feeding the infant from the bottle comprises a bendable, non-resilient hook which wraps around the person's neck with an expandable shank lying against the person's chest. A clasp made of an open-ring of elastomeric material is rotatably mounted at the end of the shank, and can be positioned in a variety of orientations to direct the bottle toward the mouth of the feeding infant.

Abstract: An alarm device for monitoring the watering needs of a plant which comprises a stick surmounted by a cylindrical box containing the electrical elements. The stick is buried in the soil of a pot holding a plant. The alarm device is powered by a battery easily installable and consists of a conductive probe detector located at the buried end of the stick. It also comprises a first integrated circuit which is switched by a backwards connected amplifier acting as a very high impedance switch which minimizes power consumption. The circuit emits a series of pulses when a threshold resistance level is reached. These pulses trigger a melody integrated circuit which produces a pleasant singing melody destined to draw the attention of the plant grower to the watering needs of a plant. The tune is repeatedly reproduced until the soil resistance detected by the probe detector has exceeded a threshold resistance level.
