Abstract
Abstract A semi-automated agglutination viewer comprising a housing having a top, a front panel, and a back. A rocker tray is rotatably supported by the housing. Power is supplied to a motor within the housing which, through intermeshing gears and a rocker arm interconnecting the gears and the tray, causes rocking of the tray. A method of serology testing comprising placing test slides on the rocker tray; adding a predetermined amount of a reagent and a test specimen to the slides; stirring the admixed reagent and test specimen; setting the controls on the length and speed of rocking of the rocker tray; and activating the rocking of the rocker tray.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
339 words
A semi-automated agglutination viewer comprising a housing including a top and a front panel; and upright back bound to said housing; magnifying means mounted in retainer means attached essentially perpendicularly to said upright back for aiding viewing of any agglutination; rocker tray means rotatably supported by said housing within the top thereof; motor means including a shaft and encompassed by said housing; power source means electrically engaging said motor means to supply power to same for rotating said motor shaft; gear means connected to said motor shaft for rotational power take-off therefrom; and a rocker arm means attached to said rocker tray means and secured eccentrically to said gear means such as to vertically reciprocate the rocker arm means from rotary power take-off from the gear means to cause rocking of the tray means; a sample handling tray; said rocker tray means comprises a rocker tray support having a rocker base having a pair of ears integrally bound to said rocker base and attaching the tray support to said housing, one of said pair of ears attaching said rocker arm means, said rocker tray support and said sample handling tray being constructed such that in operation the sample handling tray snaps into or snaps out of the rocker tray support, a pair of flexible lips protruding from said rocker base; and a rocker tray back defining a channel for receiving an edge of the sample handling tray when same is snapped into said rocker tray support, an essentially arcuate optic background means enclosed within and supported by said housing above said motor means and said gear means; a lamp means electrically engaging said power source means and supported within and by said housing; and a fluorescent lamp means positioned in the corner of the adjoining point of said upright back and said magnifying retainer means, said fluorescent lamp means electrically engaged to said power source means; and a pair of light shields, one of which is situated over said lamp means and the other over said fluorescent lamp means.
Claim 2
Dependent Claim

A semi-automated agglutination viewer comprising a housing including a top and a front panel; and upright back bound to said housing; magnifying means mounted in retainer means attached essentially perpendicularly to said upright back for aiding viewing of any agglutination; rocker tray means rotatably supported by said housing within the top thereof; motor means including a shaft and encompassed by said housing; power source means electrically engaging said motor means to supply power to same for rotating said motor shaft; gear means connected to said motor shaft for rotational power take-off therefrom; and a rocker arm means attached to said rocker tray means and secured eccentrically to said gear means such as to vertically reciprocate the rocker arm means from rotary power take-off from the gear means to cause rocking of the tray means; a sample handling tray; said rocker tray means comprises a rocker tray support having a rocker base having a pair of ears integrally bound to said rocker base and attaching the tray support to said housing, one of said pair of ears attaching said rocker arm means, said rocker tray support and said sample handling tray being constructed such that in operation the sample handling tray snaps into or snaps out of the rocker tray support, a pair of flexible lips protruding from said rocker base; and a rocker tray back defining a channel for receiving an edge of the sample handling tray when same is snapped into said rocker tray support, an essentially arcuate optic background means enclosed within and supported by said housing above said motor means and said gear means; a lamp means electrically engaging said power source means and supported within and by said housing; and a fluorescent lamp means positioned in the corner of the adjoining point of said upright back and said magnifying retainer means, said fluorescent lamp means electrically engaged to said power source means; and a pair of light shields, one of which is situated over said lamp means and the other over said fluorescent lamp means.
Claim 3
Dependent Claim
148 words
The agglutination viewer of claim 1 additionally comprising a timer means electrically engaging the power source means and selectively engaging the motor means to control the length of rocking time of the tray means; a speed control means electrically engaging the power source means and also selectively engaging the motor means to control the speed with which the rocker tray moves in its rocking mode via the gear means and the rocking arm means, and a reflected lamp source control means and a reflected fluorescent lamp source means both electrically engaging the power source means for respectively controlling the power source to said lamp means and said fluorescent lamp means for reflecting light off the optical background means and through said rocker tray support and said sample handling tray to illuminate any samples held on said handling tray so that any agglutination in the samples can be detected.
Claim 4
Dependent Claim
17 words
The agglutination viewer of claim 2 additionally comprising fiber optics system means attached to said upright back.
Claim 5
Dependent Claim
31 words
The agglutination viewer of claim 3 wherein said timer means, speed control means, reflected lamp source control means and reflected fluorescent lamp source means are all situated on said front panel.
