An apparatus and method for injecting a substance, such as a radiopharmaceutical, into the bloodstream of a subject is described. The apparatus comprises an injection means, such as a servo controlled syringe, a means for measuring the concentration of that substance in the subject's bloodstream, and means for controlling the injection in response to the measurement so that the concentration of the substance follows a predetermined function of time. The apparatus of the subject invention functions to inject a substance into a subject's bloodstream at a rate controlled by an error signal proportional to the difference between the concentration of the substance in the subject's bloodstream and the predetermined function.

Super-smooth rounded or formed articles made of thermoplastic materials including various poly(methyl methacrylate) or acrylonitrile-butadiene-styrene copolymers are produced by immersing the articles into a bath, the composition of which is slowly changed with time. The starting composition of the bath is made up of at least one solvent for the polymer and a diluent made up of at least one nonsolvent for the polymer and optional materials which are soluble in the bath. The resulting extremely smooth articles are useful as mandrels for laser fusion and should be useful for a wide variety of other purposes, for example lenses.

Patent for a car-coupling that "will greatly simplify the construction and facilitate the operation thereof by providing levers upon the end of the car" (lines 14-17); including illustration and instructions

Patent for an alarm designed to attach to windows or entryways and sound to alert residents of a burglary attempt, with illustrations.

Patent for an improved buckle that will hold straps in place, particularly those straps with irregularly sized and spaced openings.

Patent for "a new and useful air-brake mechanisms in relation to a pressure controller and distributer designed to perform the several independent and joint functions of a triple valve, a pressure-retaining valve, and a pressure relief or reducing valve."

Patent for "a new and useful car-couplers to enhance the operation of coupling." (line 5-10) including instructions and illustrations.

A system and method for monitoring the output of a laser is provided in which the output of a photodiode disposed in the cavity of the laser is used to provide a correlated indication of the laser power. The photodiode is disposed out of the laser beam to view the extraneous light generated in the laser cavity whose intensity has been found to be a direct correlation of the laser beam output power level. Further, the system provides means for monitoring the phase of the laser output beam relative to a modulated control signal through the photodiode monitor.

Patent for a simple and durable churn that quickly makes butter. The butter is churned by pumping a lever, which is connected to a strap that is wrapped around a rod, the rod goes into the container holding the cream and has hoops attached to it inside the container, and the pumping action makes the hoops quickly move back and forth.

Patent for a new and improved cover for barrels. This design calls for downward-extending flanges with wings along the perimeter of the cover. These flanges hold the cover in place over the barrel opening, but they also allow for the cover to rest at an angle on the upper rim of the barrel so that one has access to the contents of the barrel without the cover touching the ground.

Patent for a clutch and transmission device for automobiles that "is simple, compact and inexpensive in construction, and which is thoroughly practical, reliable and efficient in use." (lines 31-33), including illustrations.

Patent for an air suctioning instrument that exterminates boll-weevil and other insects that infest cotton crops. Illustrations included.

Patent for new and useful improvements in attachments for Sawmill-Dogs. This invention relates to sawmill dogs, and has for its primary object to provide a simple and efficient device for retaining the actuating lever of a lever mechanism in adjusted position.

Patent for improvements in convertible tables and ironing boards. Where a freestanding table can be converted readily into an ironing board.

Patent for a toy particularly adapted for the amusement of small children.

Certificate registering a trade-mark for "Helen Corbitt's" written in stylized text, in force from 1951-1971. It includes the official certificate and the application text explaining how the mark has been used.

Patent for a numbering indicator used to mark the status of stored batteries.

Patent for an improved mechanism for drawing water from an artesian or a driven well and which can be assembled and adjusted from outside the well.

Patent for a locomotive brake shoe that is "capable of being economically manufactured in a small foundry without the installation of special and elaborate machinery, whereby they may be produced in various repair shops local to different railroad centers" (lines 15-20), including illustrations.

Patent for an invention relating to detachable flanges found in locomotive driving boxes. Benefits and objectives are explained and illustrations are included.

Patent for vehicle-axle "with removable spindles which when they become worn may be easily and quickly removed and replaced by new ones." (lines 13-15); including illustration and instructions

Patent for a shooting gallery target that releases balls when hit in the center.

Patent for an insect destroyer that forces fire smoke into the ground, targeting ants and other insects.
