Patent CA-1094931-A (CA)
Inventor: HARTE RICHARD A
IPC: G01N21/00
Filed: 1978-10-27
Granted: 1981-02-03
Abstract: ABSTRACT OF THE DISCLOSURE A body suitable for use in the quantitative detection of an unknown quantity of a biologically derived sample suitably by radioimmunoassay, fluoro-metric detection, or by spectrophotometry.  The body includes a handle attached to a nonparticulate, nonswellable, impermeable continuous surface region.  A diagnostic reagent (e.g., an antibody) is covalently attached to the surface region.  The surface region is stirred by the handle in a solution of sample substance (e.g., antigen) for reaction with the diagnostic reagent.  In a competitive binding technique, a labelled substance (e.g., fluorochrome labelled antigen) is simultaneously contacted with the sample.  Thereafter, the surface region is washed, and the label is measured as by a fluorometer.  The technique is also applicable to the so-called "sandwich technique" in which the labelled substance (e.g., labelled antibody) is reacted with the sample substance after it has been reacted with the diagnostic reagent.  The above type of surface facilitates simple and effective separation of bound from free labelled sub-stance and allows thorough washing to cleanse the surface of residual free and non-specifically bound labelled substance.

Abstract: ABSTRACT     A multi-directional mechanical positioning apparatus comprises a set of at least three disk-type, control-drive cams rotatably supported on a base member for controlling movement of the working head of a machine tool within a plane defined by complementary axes of movement (such as the x-y axes) and along at least one additional degree of movement.  A motor is provided for rotating the control drive cams at a predetermined speed of rotation.  Cam follower linkages are coupled to respective cam followers for translating movement to a transport mechanism which supports the working head by means of a boom and is mounted for movement on base.  Additional linkages are provided which include a transport mechanism follower coupled to the transport mechanism for freely following movement of the transport mechanism in its plane of movement without interference.

Title: Steering control for an integrated brake and steering  system

Granted: 1981-09-22
Abstract: STEERING CONTROL FOR AN INTEGRATED BRAKE AND STEERING SYSTEM     ABSTRACT OF THE DISCLOSURE     A steering mechanism for use in an integrated brake and steering system. The steering mechanism has a driver gear connected to a rack mechanism by a pinion member. The driver gear is connected to a gear attached to a steering shaft by a linkage member. A carrier member attached to a rotary valve holds first and second sprocket wheels taut against the linkage member. A steering input signal applied to the steering shift by an operator creates a steering torque in the linkage member. The steering torque causes the rotary valve to move and restrict the communication from a source of fluid to develop a pressure differential across the rack mechanism. This pressure differential moves the rack and provides the driver gear with an operational rotary torque. This operational rotary torque is transmitted by the linkage to the gear on the shaft to provide a power assist in the operation of the steering gear connected to the wheels of a vehicle.

Abstract: DOUBLE SICKLE MECHANISM     The Abstract Of The Disclosure Two sickles, each slightly longer than half the width of the swath taken by the mower, are supported across the front of the mower for reciprocation in mutually opposite directions. Although the two sickles are located in the same vertical plane, they are situated in two different horizontal planes so as to permit overlap in the center during reciprocation.  To further facilitate such overlap, the backing bar to which the knife sections of one sickle are attached is located on top of the sections, while on the other sickle, the backing bar is located along the bottom of the sections.  The sections are so arranged adjacent the inner ends of the sickles that even when the sickles are at the extremes of their outward strokes away from one another, no gap is presented in the center between the two innermost sections of the two sickles, thereby promoting even cutting across the entire swath taken by the sickle assembly.
