Patent NL-1012531-C1 (NL)
Title: Surface cleaner e.g. to remove chewing gum from a surface
Inventor: WALINGA JACOB KLAAS
IPC: B05B3/06
Filed: 1999-07-07
Granted: 1999-10-25
Abstract: One or more arms rotating in the horizontal plane, each terminating in a nozzle, direct water at high pressure onto the surface to be cleaned. Water and debris are removed by suction and filtered. Rotating arms mounted in a wheeled housing are supplied with water at a pressure of 180 bar and temperature of 70-75 degrees C. Nozzles direct water jets at an angle of 28-30 degrees to the vertical to 'chisel' at surface grime. If multiple nozzles are used, alternate nozzle face in opposite directions. Skirts prevent water from spraying outside the housing.

Title: Method for control of manufacture object
Inventor: KOSTOGRYZ PETR V
IPC: G05B11/00
Filed: 1989-05-03
Granted: 1994-07-30
Abstract: FIELD: automatic control. SUBSTANCE: method involves generation of task, measuring controlled parameter of object, determination of deviation of controlled parameter and rate of deviation. Then control effect is generated which period is equal to sum of delay time and object time constant. Generation of control effect starts at beginning of each period, when task is changed or deviation exceeds toleration range of controlled parameter and neutral zone. Range of neutral zone is less than error of controlled parameter. Value of control effect is proportional to toleration range of deviation which is proportional to deviation rate when deviation is out of neutral zone. Otherwise, toleration range of deviation is proportional to residual deviation. Generation of control effect finishes and is processed at beginning of period by subtraction of constant value from initial value of control effect. amplitude of constant value is greater than non-sensitive range of control circuit. EFFECT: improved quality of control, decreased dynamic error, decreased excessive correction, decreased time of transient processes, increased precision of control. 1 dwg
