Title: Device for the assembly of toothed belts which can be carried out by robots
Inventor: BORK KLAUS
IPC: B41J19/00
Filed: 1988-06-30
Abstract: Provided for the releasable attachment of the toothed belt to the printer carriage in printing devices are eccentrically mounted pressing-on elements in the form of a belt wheel or of a toothed segment located on a lever mounted on one side. By pivoting, the pressing-on elements press the toothed belt into a chamber, which is open at the bottom, of a projection which is likewise arranged on the printer carriage until the toothed belt bears non-positively against walls of the chamber. In this end position, the pressing-on elements are locked by means of a catch device consisting of cams and pawls. In this case, both the attachment of the toothed belt to the printer carriage itself and subsequent locking can take place by means of robots. <IMAGE>

Patent DE-3838253-A1 (DE)
Title: Suction ring for operations on the human eye
Inventor: KRUMEICH JOERG H DR MED
IPC: A61F9/013
Filed: 1988-11-11
Abstract: The suction ring of the application is intended to fix the human eye during surgery. Whereas hitherto, only rings without suction permitted the intraocular pressure to remain unchanged or whereas the suction rings used for a desired increase of the pressure comprised a hollow profile that was open towards the inside, the ring of the present application permits secure fixation of the eye without deforming the eyeball or increasing the internal pressure. The ring comprises an outer rectangular profile (1) which carries an inner member (2) that rests against the eye, extends annularly, has a triangular cross-section and leaves two channels via webs (4) between the inner member (2) and the ring wall (1) in order to achieve a reduced pressure. The circularly extending inner wall (2) lying between the two channels rests against the eye and avoids deformation of the eye by the fixing suction. Fixation of the ring on the eye is guaranteed by the two suction channels (3) without it being possible for the eye wall to be drawn into the hollow profile. The suction is generated by an external vacuum source through the hollow handle (6). The central ring opening (7) can be used to receive additional concentric rings which permit guidance of a knife.   <IMAGE>

Inventor: BUTZ KONRAD
IPC: B28B7/00
Filed: 1988-11-24
Abstract: A device is to be developed in such a manner that the noise level caused by the vibrating unit is reduced considerably. According to the invention, the arrangement for locking the mould frame (13) to the vibrating table (12) is a symmetrically designed multi-joint mechanism with at least two degrees of freedom. The drive members are designed as two pressure levers (37, 38) which can be pivoted about horizontal shafts (39, 40). Each pressure lever (37, 38) is provided with an arm (41, 42) having a pressure piece (43, 44). Each pressure piece (43, 44) can be pressed against an abutment of the mould frame (13). The multi-joint mechanism is actuated by means of a hydraulic cylinder (32), the central longitudinal axis of which is the axis of symmetry of the multi-joint mechanism. The multi-joint mechanism is expediently a seven-member mechanism which works according to the articulated-lever principle, as a result of which extremely high forces can be applied in association with the hydraulic cylinder (32). The hydraulic cylinder (32) and the multi-joint mechanism are arranged on a common support plate (31) which follows the movement of the vibrating table (12) so that the inevitable varying forces are no longer carried off via the machine frame. The device according to the invention is suitable for manufacturing plate-shaped structural parts, paving stones, kerbstones and the like. <IMAGE>

Title: Vibratory fluidised bed for sorting scrap metal - uses multi-layer bed to avoid need for air blast at outlet end of bed
Inventor: KALDENBACH ERWIN
IPC: B03B5/46
Filed: 1990-08-17
Abstract: The method is especially applicable to the sifting of mixes of non-ferrous metal scrap, and is distinguished by the use of a multi-layer fluidised bed in which the bulk density of the layers may be varied by choice of material, e.g. steel shot, glass beads, and particle diameter. The material of the bottom layer must have a bulk density at rest equal to the specific weight of the heaviest material to be separated. The bed material of lowerbulk density forms the upper layer. The bed material (49,47) is admeitted admitted to the vibratory bed (8) through offset chutes (51,52). The material mix (35,48) is fed in at the front end and as it moves along the bed the lighter constituent '35) floats to the upper layer. The segregated metal emerges from the bed past a gate (36) dividing the output into two streams. ADVANTAGE - Does not require use of air blast. Environmentally friendly. Three materials can be separated in two layer bed if required.
