Title: Submersible agitator esp. for waste water in activation ponds - in which agitator motor is attached to column fixed at upper end and resting on floor of pond at other end, and length of column is greater than depth of water
Inventor: KOCH FRED
IPC: B01F7/00
Filed: 1991-04-17
Abstract: A submerged-motor agitator for circulating fluids has a propeller driven by a motor attached to a column which is fixed at one end to a wall surrounding a body of water or to a bridge above the surface of the water, and is provided at the other end with a support which rests on the floor of the tank or pond. The length of the column and the support is greater than the distance from the upper connection point to the floor of the tank or pond, and the support is not connected to the floor but simply rests on it. The motor is attached to the column such that the reaction force from the agitator lies in the plane of the axis of the column and a vertical line between the upper fixing point and the floor of the tank or pond, and is in the direction from the column towards this vertical line. The column can pivot about its upper connection point in the plane defined above, and the support is connected by a pivoting joint to the lower end of the column. This joint is in the form of a ball joint and the support is in the form of a plate whose flat side rests on the floor of the tank of pond. The motor can be moved along the length of the column. USE/ADVANTAGE - Used principally for circulating waste water in activation ponds or tanks. The proposed agitator is simple to construct and to operate and requires no fixing of the column to the floor of the tank or pond

Title: Automatic milking machine with adaptive milking parameters - determined in dependence on detected milk flow and milk quantity for each cow
Inventor: SCHILLINGMANN DIETER DIPL ING
IPC: A01J7/02
Filed: 1991-04-26
Abstract: The milking cups (3), are secured to the teats of the cow via a vacuum. Each cup (3) leads to an expansion chamber which is emptied each time the chamber is filled with a given quantity of expressed milk. The quantity of milk and the milk flowrate for each cow are measured and fed to an evaluation processor (47) to adjust the milking parameters. Pref. the milk flow is determined from the number of times the expansion chamber is emptied within a standard unit of time, the milk quantity being determined from the sum of the corresp. milk weights. ADVANTAGE - Allows milking parameters to be adjusted for each individual cow, while allowing it to be examined while, and immediately after, milking. Teats protected from possible injury.

Title: Automatic shift device for transmission of motor vehicle - has separate piston-type actuators operated hydraulically to engage and disengage clutch with axially movable plates
Inventor: PAULSEN LUTZ DR ING
IPC: F16H61/02
Filed: 1991-06-25
Abstract: The input shaft of the transmission is driven from the crankshaft via a hydrodynamic torque converter and brake. The friction clutch (5) for first and reverse gears is engaged solely by an axial-piston actuator (8). In the neutral setting both this and the disengaging actuator (9) are held in a position (10) corresp. to engagement of the clutch (5), with hydraulic pressure absent from the lines (12, 13) whereby the respective actuators (8, 9) are supplied.

A second piston surface (18) in the corresp. chamber (46) is connected via a second pressure line (13) to a second 3/2-way valve (22) which is controlled by a second electromagnetic 3/2-way valve (30). USE/ADVANTAGE - In stop-and-start inner-city traffic, drive is re-engaged from neutral so rapidly that hill-starts are achieved without running back.

Title: Submerged water pump - has chambers rotating through thirty degrees with pressure differential minimisation to reduce input power requirement
Inventor: GEISS KLAUS
IPC: F04C9/00
Filed: 1991-06-28
Abstract: The submerged pump for removal of large or small amounts of water with minimum power requirement has a fixed section (1) and a movable cylinder (2), which is separated into chambers (4, 5) via a separating wall (3). The cylinder rotates through an angle of thirty degrees left and right back over the fixed section. A rotation to the left closes the right chamber (4) and opens the air connection. The left chamber (5) is opened and its air connection closed. This enables air to be drawn in with minimum pressure to the right chamber, and water via the fixed section is forced outside due to greater external pressure on the chamber. This procedure repeates with a return rotation to the right. Since the overall external pressure on the air filled chamber is equal with these rotations, the required power to produce rotation, via a motor, is less. ADVANTAGE - Rapid water removal using minimum power.
