Title: Method and control device for a hydraulic hammer
Inventor: AXINTI GAVRIL
IPC: B06B1/18
Filed: 1982-06-08
Granted: 1987-11-12
Abstract: The control system, for a hydraulic hammer or excavator, consists of hydraulic binary logic components controlled by the output signal from a hydraulic processor. This analyses signals from a store and power generator and regulates fluid flow to initiate the lifting and dropping of e.g. a hammer. The processor produces signals to open and close hydraulic logic components that distribute the power from the pump and from the store over the surfaces of the hammer, depending on the pressure in the store, on the position of the hammer and on the pressure in the pump circuit.

Title: Row sensing apparatus for a crop harvester
Inventor: WILLIAMS TERRY ARDEN
IPC: A01B69/00
Filed: 1984-08-30
Granted: 1988-03-03
Abstract: A forage harvester (11), pulled via its tongue (16) by a tractor, has dividers (19, 21) between which a crop row (18) is received, and each divider (19, 21) has a row sensing unit (41, 43) bolted to it. The crop row (18) passes between a pair of arms (47, 48) of the unit. An arm (47, 48) is deflected, when the machine is misaligned with the row (18), the arm (47, 48) having an upright pivot shaft (79). The arm (47, 48) carries an actuator plate (95) which closes a switch (145) to trigger a guidance control circuit (45) to steer the harvester by way of a piston and cylinder (33) moving the tongue (16) to return the harvester (11) to alignment with the crop row (18). To enable the harvester (11) to be reversed without the crop row (18) fouling the crop-engaging arms (47, 48) each arm is formed with a trailing portion which curves rearwardly through an angle greater than a right angle toward the divider (19, 21) and then terminates below the divider (19, 21) so that crop can pass smoothly over the arm not only when the harvester is travelling forward, but also when it is reversed.

IPC: D02G3/26

Granted: 1990-01-25
Abstract: The method of, and apparatus for, producing a yarn uses a friction spinning device comprising a perforated first friction spinning drum and a second friction spinning drum which can also be perforated. Two fiber feed passages project to the first friction spinning drum and are each supplied by opening assemblies which individualize or individually separate the fibers. The fibers are transported toward the first friction spinning drum using a feed air stream in the fiber passages. This feed air stream is produced by the first friction spinning drum which is maintained under sub-pressure. Advantageously, the fiber double-feed to the friction spinning drum permits supplying two different fiber types to the same yarn end. Also, different inclinations of the fibers at the friction spinning drum can be obtained by different inclinations of the fiber feed passages in order to produce yarns of different character. The first and second friction spinning drums can be each divided into cooperating drum sections to define a first pair of coacting drum sections and spaced therefrom a second pair of coacting drum sections. The respective pairs of drum sections can be operated at different rotational speeds and can be subjected to different vacuum conditions.
