A liquid manure applicator comprises a tank for holding a supply of liquid manure that is distributed onto a farm field through a distributor having a plurality of distribution ports and hoses. The hoses lead to individual distribution tools that include a pair or rotary coulters and a bellows for applying downforce to the coulters.

A method for thawing and infusing partially frozen fruits or vegetables. Individually quick frozen fruits or vegetables are introduced into a mixing kettle. An infusion solution is circulated from a solution tank, through a bed of fruits or vegetables, and back to a solution tank. The infusion solution is maintained at a temperature of about 45° to about 50° F. and at a Brix of about 40° to about 50°. The infusion solution is pumped and circulated at a high rate which reduces thaw time but does not result in product degradation. After thawing, the pumping and re-circulating rate is decreased to allow for increased infusion efficiency. Pressure pulses are applied to the product in the mixing tank which decreases the infusion time. Thus, thawed and infused fruit and vegetables are produced quickly and with minimal product degradation.

The invention provides an elevator device capable of making the passengers sense the pressure change and having the enough time to perform the swallow action without abrupt change of pressure, when increasing or reducing the pressure in an elevator car. A pressure adjustment device (2) capable of increasing or reducing the pressure in the elevator car (1) is controlled by a controlling device (4), thus the pressure in the elevator car (1) is increased and reduced in preset time and the increased or reduced pressure is kept for preset time. The abrupt change of pressure is prevented by the above control, thus ear function obstruction due to the abrupt pressure change is alleviated and the pressure change is fully sensed by the passengers. Because the increased or reduced pressure is kept for a preset time, the passengers have the enough time to perform the swallow action and the ear obstruction feeling due to electric pressure change is eliminated and the ear obstruction feeling and discomfort feeling can be eliminated at the first opportunity.
