From The Boston Globe - Apr 24, 1904:

Bats have been the subject of brain cogitations by ambitious inventors. Some years ago the players became familiar with what was called the flat bat. This was never patented, but it showed the inventive genius of some player. This bat was made by shaving one of the round bats with a knife until a part of the bat near the end was flat. The object of this was to give the player a chance to bunt the ball by catching it a short clip...

There was another bat invented, however, and the man who originated it had such faith in his idea that he had it patented in 1890. This bat had a curve in it and was something like a lacrosse stick. According to the theory of the inventor, Emile Kinst, when the ball was struck by a certain portion of the bat, in addition to the regular flight produced by the blow the ball would receive a rotary motion more or less violent. The result was supposed to be a ball not only difficult to handle by the fielder if it were to come straight at him, but also hard to hold if it were a fly and he got under it, because of the spinning produced by the bat.

It was also designed to produce the effect of a bunt, but in a better way, for the inventor claimed his bat would cause the ball to land near the batter and stay there under certain conditions. With these results Mr. Kinst claimed that it would make the game more difficult to play, and therefore more interesting and exciting. But his hopes were not realized, for the bat never got the official sanction of the league.

To operate the assembly, the operator places the inlet tube with its valve open adjacent his anal region from which a colonic gas is discharged. The piston is then withdrawn to a degree producing a negative pressure to inhale the gas into the combustion chamber to intermix with the air therein to create a combustible mixture. The ignitor is then activated to explode the mixture in the chamber and fire the missile into space.

A recreational activity practiced by some individuals is ignition of one's own flatus. This is performed by using a lit match or candle, or a cigarette lighter. So widespread is this activity that there are web sites on the Internet devoted exclusively to explaining proper lighting techniques.

A major drawback of this popular practice is that it usually involves the hazardous coupling of fire, combustible gases and inebriated participants. Reports of serious burns to body parts are not uncommon, this being especially true when the participants remove their clothing...

In view of the foregoing, the main object of this invention is to provide a safe toy which exploits the combustible properties of flatus to fire a toy missile into space.

A balance watch, a combination of two watches, one measuring hours, the other measuring minutes and/or seconds. Each watch is worn on a separate wrist simultaneously.

The apparatus includes a supporting platform having a Y-type shape and including an upper beam configured for extending between a nose bridge and a forehead of the patient and for positioning on the forehead, a left leg and a right leg coupled to the upper beam, and configured for straddling a nose bridge of the patient and for positioning on patient's left and right cheeks, and a cross-arm mounted on the upper beam of the supporting platform. The apparatus also includes an opening assembly mounted on the cross-arm and configured for pulling an upper eyelid up for exposing an eye and retaining the eye of the patient in the open position.
