Abstract: An artificial insemination device is formed by attaching a semen filled straw or tube to one end of a pipette to which a syringe is attached at the other end. An anchorable tip is attached to the other end of the semen filled tube. The semen filled tube is attached by forming tapered bores in the pipette and anchorable tip so that semen filled tubes of various diameters can be press fit into the tapered bores. The pipette-tube-tip assembly is inserted into the animal's vagina using a speculum until the tip enters the cervix, and a seal is formed between the tip and cervix by inflating an attached balloon. The syringe, which contains a diluent fluid, is pushed to force semen and diluent fluid out through ejection port(s) in the tip into the animal's uterus. Optimum amounts of semen and diluent fluid can be delivered to various sized animals.

Abstract: A stepping motor comprising a plurality of stages which may be selectively activated to effect stepping movement of the motor, and which are mounted along a common rotor shaft to achieve considerable reduction in motor size and minimum diameter, whereby sequential activation of the stages results in successive rotor steps with direction being determined by the particular activating sequence followed.

Abstract: A system for safely and positively detonating high-explosive munitions, including a source of electrical signals, a split-phase square-loop transformer responsive solely to a unique series of signals from the source for charging an energy storage circuit through a voltage doubling circuit, and a spark-gap trigger for initiating discharge of the energy in the storage circuit to actuate a detonator and thereby fire the munitions.
