Title: Plant seedling holding and dispensing mechanism
Inventor: HUBER ERNST
IPC: A01C11/02
Filed: 1991-06-17
Abstract: A seedling holding and dispensing mechanism used on planters having a planting arm which is intermittently extended downwardly into the soil. The seedling holder and dispenser is preferably mounted along the trailing edge of the planting arm. The seedling holder includes a first jaw and a second jaw. The first jaw is preferably mounted to the trailing edge of the planting arm in a fixed position. The second jaw is mounted for movement relative to the first jaw to allow clamping of the seedlings. The second jaw can be pivotally mounted, such as by using a connecting rod which is pivoted torsionally about a longitudinal axis. A proximate end of the connecting rod is adapted to have a lever arm. The mechanism preferably uses retraction and extension position actuators which automatically open the jaws in both the retracted loading position and the extended discharging position. A biasing spring biases the jaws together when not actuated to thereby hold the seedling as it is moved downwardly and inserted into the soil.

Title: Mixer
Inventor: GOETTLER HANS J
IPC: B01F7/00
Filed: 1992-01-23
Abstract: Patent MIXER                 Abstract of the Disclosure This shear mixer for polymeric material has two mateable bodies that, when pressed in mating condition together, form a reverse flow path for the movement of the material being mixed.  The mixer has two mixing gaps, each defined by a primary wall surface on one body and an opposing wall surface on the other.  Contractive movement of the two bodies together effectively causes the linear length of each mixing gap to increase and also causes one wall of each mixing gap to move in a direction opposite to the flow of material through the mixing gap.  The mixing method involves not only increasing the length of a mixing gap as material is pushed through it for mixing, but also causing flow of material through one mixing gap to be in a direction opposite but parallel to the flow of material through the other mixing gap.
