Title: Concave for an agricultural combine
Inventor: HEIM DANIEL MARC
IPC: A01F12/24
Filed: 2000-02-03
Granted: 2005-08-02
Abstract: A concave for an agricultural combine having an array of straight rectangular bars and straight round bars spaced from one another and extending axially of the rotor or cylinder to form a threshing surface and to form openings therebetween for grain to pass through.

Abstract: A hydraulic drilling jar having an outer generally hollow housing, an inner mandrel, an anvil, a hammer, and a hydraulic valve. The mandrel has a first end securable to a drill string and a second end slidably receivable within an end of the housing to form a fluid chamber therewith. The mandrel is slidable within the housing from a contracted position to an extended position. One of the anvil and the hammer is situated on the housing and the other on the mandrel. The valve is received around the second end of the mandrel and in the fluid chamber. Extension of the jar causes the valve to seat against the housing and the mandrel to bifurcate the fluid chamber into first and second portions while pressurizing the first portion to place the jar in a cocked configuration. Further extension of the jar causes a high impact loading of the anvil and hammer portions.

Granted: 2008-04-08
Abstract: Formerly, several machines or workstations have been required for bordering and closing creases, especially on pipes used in ventilation technology.  The invention provides a machine that can carry out all of the operations without the workpiece having to be rechucked. By positioning the closing wheel (6), known per se, underneath the work surface, all of the operations, including the insertion of a sealing strip, can be carried out precisely and economically at the same workstation.  According to a preferred method, a bead is first pressed in the workpiece (100) using a moulding roll (2) and a beading and feeding roll (1). During machining with these hydromechanically driven rolls (2, 1), the workpiece (100) is held in the correct working position. The closing process is carried out from the bottom and enables optimum adjustment of the angle of intervention on the closing wheel (6) and reduces wear.

Abstract: Wavelength-multiplexed light including wavelength lights is separated at periodic intervals of wavelength by means of a periodic optical filter, thereby generating wavelength groups composed of the following wavelength lights. Then, an optical switching section selects any one of the wavelength groups and introduces the selected wavelength group into a periodic optical filter. Making the period p of the periodic optical filter different from the period q of the periodic optical filter causes the wavelength lights included in each wavelength group to be outputted at the different separation ports of the periodic optical filter. As a result, each wavelength light is separated completely from the other wavelength lights.
