Abstract: The invention relates to an internal grab with two gripping arms which are held in a frame movably parallel to themselves and to one another and, under the effect of a drive, are displaceable relative to one another into an opening position or a holding position. According to the invention, the gripping arms (1, 2) can, under the effect of the drive (12), be indirectly displaced into an opening position with mutual support and into a splayed holding position by the drive moving a control ring (8) to and fro in the longitudinal direction of the gripping arms (1, 2), the opening (8a) of which delimits the mutual spacing of the gripping arms. Guided along simultaneously with the control ring (8) is an expanding mandrel (6) arranged between the gripping arms (1, 2), which in the holding position of the control ring (8) extends at least as far as into the region of the holding section of the holding heads (1c, 2d); this is designed as a projection (1k, 2l) facing in the direction of the displacement movement (double arrow 7) of the gripping arms. <IMAGE>

The aim is to achieve a stable press-channel feed and a uniform channel filling for all types of crop. The object of the invention is to design the feed device in such a way that a plurality of crop portions are grasped by the conveying tines and precompacted in the feed channel and the feed into the press channel of the last portion completing the filling quantity takes place with a thrust. This is achieved in that connected to the crank mechanism (2) is a link (5), to which is connected a follow-up crank (7) which transmits the revolving non-uniform rotational movement via a shaft (8), mounted in the press-channel side wall (6) eccentrically to the crank mechanism (2), and a control crank (9) arranged on said shaft (8), via a connecting piece (10) fastened to the rotor shaft (13) by means of a bolt (11), and which pivots the curved track (12) opposite to the direction of rotation of the rotor. <IMAGE>

A piston (71) is slidably fitted within each of the cylinders (70) and is reciprocated by a drive mechanism which includes a member having a surface with an adjustable incline angle. The incline angle is controlled by the pressure situation in the crank chamber (22). The pressure in the crank chamber (22) is controlled by a control mechanism which comprises a passageway (152) communicating between the crank chamber (22) and a suction chamber (241) and a valve device (19) to control the closing and opening of the passageway (152).

Abstract: A system for maintaining a downhole instrumentation package in a roll stabilised orientation with respect to a drill string comprises an instrument carrier (812) which is mounted within a drill collar (810) for rotation about the longitudinal axis of the collar. An impeller (815) is mounted on the instrument carrier so as to rotate the carrier relatively to the drill collar as a result of the flow of drilling fluid along the drill collar during drilling. The torque transmitted to the instrument carrier (812) is controlled, in response to signals from sensors in the carrier which respond to the rotational orientation of the carrier, and input signals indicating the required roll angle of the carrier, so as to rotate the carrier (812) in the opposite direction to the drill collar (810) and at the same speed, so as to maintain the carrier non-rotating in space and hence roll stabilised. The torque may be controlled by controlling a variable coupling (851,852) between the impeller and the carrier and/or by controlling a brake (857), for example in the form of a differential gear mechanism, between the carrier and the drill collar.

Abstract: Disclosed is a process for preparing a multilayered cylindrical article such as a drum or a seamless belt which comprises introducing into a cylindrical mold (1) a composition comprising a liquid, uncured resin material and a filler material of a density different from that of the uncured resin material, spinning the mold about its axis at a speed sufficient to cause separation of the uncured resin material and the filler material into discrete layers, and subsequently curing the uncured resin to form a cylindrical article having at least two layers (8,10), wherein the outermost layer comprises the material of higher density. Subsequent to formation, the multilayered cylindrical article can be coated with additional layers. Further, additional layers can be added to the inside surface of the cylinder by introducing the additional layer material into the mold and spin casting to form a layer. The cylindrical articles can be employed as imaging members in ionographic, electrophotographic, and similar imaging processes.

Abstract: A System for Collecting Weakly Scattered Optical Signals (100) employs a laser (102) which illuminates an unknown gas (107) contained by a long hollow chamber (105) having a highly reflective coating (106 or 111). The illuminating electromagnetic radiation (103) from the laser is directed along the entire length (L) of the chamber and collides with the vibrating molecules of the unknown gas within the containment tube. The collisions cause the emission of shifted electromagnetic radiation (112) that is separated from the incident light and then is collected through one of the apertures (108) of the tube. The scattered photons are then guided to a collection optics assembly (116), and a photodetector (124).

Abstract: In the commercially conventional handle units, there is a helical spring performing the function of pressing down a plate serving as a screw cap and of holding it in the covering position. In the handle unit according to the invention, there is no need for the hitherto conventional helical spring. The handle unit consists essentially of the handle element (11) made of shell-cast aluminium, a rose (16), a detent bush (17) and a square pin (19). Since a helical spring no longer has to be provided, no recess for the helical spring is needed in the handle element (11). This affords a more favourable shape for producing the handle element by the shell-cast aluminium process. Furthermore, the absence of a recess enables the designer to make the handle neck more slender than in the hitherto existing handles. The rose (16) has two passage orifices (25) for screws (21). In the region of the passage orifices (25) is located a recess (29), into which a screw cap (15) can be inserted. The screw cap (15) possesses two fingers (39) with barbs (41). By displacement counter to the force of the spring (45), the screw cap (15) can, if required, be removed. Since the screw caps are used only after the fitting has been installed in the window (22), there is no risk that they will be scratched during production, transport or installation. <IMAGE>
