Patent EP-0023803-A1 (EP)
Inventor: THOMAS DAVID WILLIAM
IPC: A01C7/04
Filed: 1980-07-24
Abstract: A seed drill apparatus has a seed storage box SB with seed inlet manifold (2) to convey seeds to a rotatable collector wheel (5) having a number of peripheral seed receiving cavities (6). The seeds are ejected singly, assisted by a blade edge 11 running in a groove (5a) joining the centres of the cavities, through an aperture (B) in casing (1) to fall into a groove (8) around the periphery of a distributor wheel (7). The groove (8) is subdivided by stops (9) into arcuate sectors each of which receives a seed. A retardation device (12) catches a seed in the groove (8) and holds same until carried on by a stop (9). The seed falls to the ground through outlet (13). The wheel (7) has a peripheral speed equal to the linear speed of motion over the ground and wheel (5) rotates more slowly with a reduction dependent on the ratio between the number of cavities (6) and number of stops (9). The retardation device (12) ensures accuracy of spacing by providing for discharge of each seed only when in abutment with a stop (9).

Abstract: The bearing comprises a double rolling bearing 3, and a single rolling bearing 4, each of low conicity and equipped with rollers, such as 7a, having axial perforations 17a coinciding with perforations in the cage; the external ring 8c2 of the rolling bearing 4 receives, from springs 14, an axial thrust transmitted by the spindle 2 to the rolling bearing 3, which eliminates all play in the bearing. According to the invention, a single mass of lubricant passes through a cooler and then through the axial perforations of the rollers, in a manner such as to fill completely the annular chambers 18b and 19b between the two rolling bearings and balance them thermally. The invention is applicable, in particular, to high-precision machine tools. <IMAGE>

Abstract: A method for thermal treatment, especially drying, of finely particulated bulk material comprises the steps of stirring the material in a reactor by means of a rotating stirrer while simultaneously discharging a heated gas under pressure through openings in a hollow arm of the stirrer so as to form in the reactor a whirling fluidized bed from the material, and introducing the necessary amount of heat for the thermal treatment of the material at least in part through a heat exchanger extending into the whirling fluidized bed. The apparatus for carrying out the method mainly comprises an arrangement for feeding the material through an inlet into a reactor forming a whirling chamber in which a rotating stirring device is arranged having at least one hollow stirring arm provided with openings through which a preferably heated gas under pressure is discharged into the material so as to form a whirling fluidized bed in the reactor, a heat exchanger extending through the fluidized bed, and an outlet for discharging the gas and treated material from the reactor. The reactor may also include an arrangement extending into the whirling fluidized bed for retarding flow of the material from the inlet to the outlet of the reactor, which arrangement may be constituted by a heat exchanger of lamellar construction so that the material will pass in cascades through the reactor.

Abstract: A leg aid device and method for increasing the stamina of a body-supporting user's leg for repeated flexure and extension at the knee. The device comprises elongated flexibly resilient biasing means (14) for placement in approximate alignment with a user's leg from a level near the ankle area up to at least the level of the midthigh area. The biasing means (14) is adapted to bias a user's leg toward a straightened condition without significant torsion or twisting of the leg. Holding means (18, 20) maintains the biasing means (14) approximately aligned upon a user's leg for bending yieldingly therewith during flexure thereof at the knee. The biasing means (14), when held by the holding means (18,20) upon a body-supporting user's leg, functions to support a portion of the user's body weight during times the biasing means (14) is in bent condition with the user's leg in flexed condition, and functions to aid the user's leg muscles in causing extension of the user's leg from flexed condition as the biasing means resiliently returns toward a straightened condition with the extension of the user's leg.

Abstract: Method and apparatus for recording color pictures wherein color proofs are made before the actual printing for quality control in multicolor printing processes. The color pictures are exposed on a chromatic material wherein the exposed colors must coincide with the colors which are later to be printed on paper. So as to achieve the color equivalent color picture exposure, the required color density values for the chromatic material of the selected printed and exposed colors are identified with a visual or mensurational comparison of the CIE coordinates. The identified color density values for the exposed colors are allocated to the corresponding color separation values of the colors to be printed and during recording the allocated color density values are utilized instead of the color separation values and are converted into signals for driving a color exposure unit for example a proof recorder.
