Abdominal Supporter.
Patent for a new and improved abdominal supporter. This design "consist[s] of the waist-belt, the abdominal sector-shaped pads hung from the waist-belt by elastic straps, the straps buttoned to the belt behind and to the bottom of the abdominal pads in front, the side straps connecting the abdominal pads with the pieces at the back, and the front strap connecting the two abdominal pads together with the shoulder-straps" (lines 70-79).

Abdominal Supporter.
Patent for a new and improved supporter for the abdomen during pregnancy. This design "consists of an abdominal sack for the support of the abdomen in pregnancy, which is contrived with supporting-bands adapted for supporting it from the shoulders of the wearer, where the weight can be best sustained, and so as to entirely avoid the belt commonly used, and thus relieve the stomach and liver from the pressure and irritation which it produces" (lines 7-15).

Abrasion Resistant Coating and Method of making the same
An abrasion resistant coating is created by adding a ductile phase to a brittle matrix phase during spray coating where an Al-Cu-Fe quasicrystalline phase (brittle matrix) and an FeAl intermetallic (ductile phase) are combined. This composite coating produces a coating mostly of quasicrystal phase and an inter-splat layer of the FeAl phase to help reduce porosity and cracking within the coating. Coatings are prepared by plasma spraying unblended and blended quasicrystal and intermetallic powders. The blended powders contain 1, 5, 10 and 20 volume percent of the intermetallic powders. The unblended powders are either 100 volume percent quasicrystalline or 100 volume percent intermetallic; these unblended powders were studied for comparison to the others. Sufficient ductile phase should be added to the brittle matrix to transform abrasive wear mode from brittle fracture to plastic deformation, while at the same time the hardness of the composite should not be reduced below that of the original brittle phase material.

ac-resistance-measuring instrument
An auto-ranging ac resistance measuring instrument for remote measurement of the resistance of an electrical device or circuit connected to the instrument includes a signal generator which generates an ac excitation signal for application to a load, including the device and the transmission line, a monitoring circuit which provides a digitally encoded signal representing the voltage across the load, and a microprocessor which operates under program control to provide an auto-ranging function by which range resistance is connected in circuit with the load to limit the load voltage to an acceptable range for the instrument, and an auto-compensating function by which compensating capacitance is connected in shunt with the range resistance to compensate for the effects of line capacitance.
