Title: Antibody coated crystal chemical sensor
Inventor: VALI VICTOR
IPC: G01N33/53
Filed: 1991-03-26
Abstract: ANTIBODY COATED CRYSTAL CHEMICAL SENSOR               ABSTRACT A sensor for detecting the presence of a particular chemical by determining the absolute frequency shift in the oscillating frequency of an antibody-coated oscillator. Specific antibodies deposited on a high Q crystal oscillator detect the change in frequen-cy as chemical particulates become trapped by the antibodies and change the effective mass of the crystal. In one embodiment, two oscillating crystals are used, one that has been coated with the antibodies, and one that is uncoated. This permits detection of frequency differences between the oscillating frequencies of the two crystals, thus elim-inating pressure, temperature, and humidity corrections that conventionally must be made. The sensor maintains a high specificity by using antibodies that are specifically related to the chemical to be detected, while achieving relatively good sensitivity by using high Q oscillators, such as quartz or sapphire, and eliminating drift problems due to temperature, pressure, and humidity. In a second embodiment, a single crystal is used having antibodies coated at specific nodal locations associated with harmonics of the fundamental frequency of oscillation of the crystal. Harmonic amplitudes are mea-sured to determine the presence of the chemical of interest.

Abstract: ABSTRACT A flexible valve retainer for a piston and suction valve assembly of a reciprocating piston hermetic compressor assembly. In the compressor assembly, the suction valve opens as a result of the fluid pressure generated by the reciprocating movement of the piston in the cylinder.  As it opens, the suction valve is axially displaced from a closed position on the top surface of the piston to an open position a fixed distance therefrom, whereupon further axial movement is prevented as the suction valve strikes the valve retainer.  The radially outer portion of the valve retainer deflects as a result of the impact with the suction valve.  This deflection of the valve retainer lessens the detrimental effects caused by repeated impact between the suction valve and retainer.  The valve retainer is formed from a flexible material such as spring steel or Swedish steel.  The valve retainer comprises at least one washer coaxial with the suction valve, and spaced said fixed distance therefrom.  In a preferred embodiment, the valve retainer comprises two or three washers stacked one atop another.  The stiffness of the valve retainer is less than about 331,000 lbf/in, and the thickness of the valve retainer is preferably between about 0.028 and 0.060 inch.
