Abstract: A method and a device are proposed for the injection of very small amounts of samples into cells (74) with the aid of a microcapillary (10). During the injection, a constant injection pressure of about 0.12 bar, provided by a pressurized cylinder (46) is applied ot the microcapillary (10), which is reduced after the completion of the injection to a holding pressure of 0.02 bar until the next cell (64) is to be injected. A high-pressure (p.sub.1) supplied from another pressurized cylinder (44) serves for blowing out the microcapillary tip (12). A three-way valve (42) permits simple and rapid switching between the various pressure (p.sub.1, p.sub.2 and p.sub.3). Reproducible amounts of sample in the range from 10.sup.-11 ml to 10.sup.-13 ml can be injected reprodicibly, simply and rapidly.

Abstract: A method of playing a bowling game in which players are allowed a preselected number of balls to knock down all pins in each of a plurality of frames. A sequence of a plurality of differing pin setups of a constant number of pins is selected for each frame, up to a maximum of nine pins. Each player is required to deliver at least one ball in each of the frames. The number of pins knocked down by each player in each frame is counted, with strikes recorded for all pins knocked down by a first ball and spares recorded for all pins knocked down by a second ball. The number of pins knocked down by the respective player on the next two balls is added if a strike was recorded in the previous frame. The number of pins knocked down by the respective player on the next one ball is added if a spare was recorded in the previous frame. This determines the score for each player for each frame, which is recorded.

Abstract: A refrigerator control for operating a refrigerator which may experience an abnormal temperature condition due to operation in low ambient temperatures includes a temperature sensor for sensing the temperature of a portion of a refrigerator compartment in order to detect an abnormally low temperature in another portion of the compartment. If the compartment temperature at the end of a predetermined length of time since cooling was last supplied to the compartment is below a predetermined value, then an abnormal condition is assumed to exist and corrective action is taken to eliminate the abnormal condition. A preferred form of corrective action is to prevent compressor re-energization until the compartment temperature reaches a second predetermined value.
