Abstract: A transporter has transfer elements for moving an empty cloth beam into a position between a loom and a transporter or into a winding station of the loom. In addition, the transporter carries a curved wedge for engaging against the positioned empty cloth beam so as to hold a length of cloth between the full cloth beam on the transporter and the wedge. A cutting device serves to cut the cloth between the two beams. In one embodiment, the wedge moves about the cloth beam to form and insert a loop of cloth in a pressing zone formed by the cloth beam and the incoming cloth. In a second embodiment, the cloth beam carries resilient elements to form a pressing zone and is rotated relative to a stationary wedge in order to insert a loop of cloth between the resilient elements and the surface of the empty cloth beam.

Abstract: The surface of a workpiece is provided with a surface layer. Initially, the workpiece is inductively heated by a HF/MF generator to a first temperature and subsequently heated further by a laser beam with coating material being applied to the region of the laser beam in an amount sufficient to form a surface layer on the workpiece. The generator and the laser source are able to operate simultaneously to effect a high quality surface layer of relatively thin thickness.

Abstract: The weft yarn insertion mechanism exhibits at the side of the shed (6) where the weft yarn comes out a yarn holder device (13) for taking over and releasing the end (4") of the weft yarn, which comprises essentially two gripping parts (16, 17) and one nozzle (18). Preferably the one gripping part (16) is stationary and the other gripping part (17) movable and together they form a wedge shaped gripping gap (24). A blowing nozzle or suction nozzle (18) sucks or blows the end (4") of the end of the weft yarn into the gripping gap (24) at the moment when the weft insertion is finished.

Abstract: A battery of solid electrolytic fuel cells is provided with heat conductive temperature equalizing members disposed in alternating relation with electrochemically electrode active structures of the fuel cells. The heat produced by the electrochemical reaction is dissipated by the air which is applied to the fuel cells to provide the oxygen required for the reactions. The transfer of the heat of reaction to the air is largely brought about before the air comes into contact with the electrochemically active structures.

Abstract: The card cage is provided with an air cooling system employing deformable baffles in the air flow path to the spaces between the printed circuit cards. The baffles are deformed upon assembly in order to adapt to the thermal conditions to be expected during operation of the card cage. The baffles provide minimum openings which produce a pressure in front of the openings which effects a more uniform flow distribution via the openings and which also permits an increase in the air flow rate to the printed circuit cards which are subject to strong thermal stresses.

Abstract: A large diesel engine is provided with a manifold arrangement in which a catalytically coated static mixer is disposed within an exhaust manifold. In addition, nozzles are provided in an annular chamber between the static mixer and the exhaust manifold in order to introduce a reducing agent into the flow of exhaust gas prior to entry into the static mixer. Alternatively, the reducing agent can be injected via a nozzle centrally located in a cover at the end of the manifold.

Abstract: A weft yarn changer on a projectile loom has a pivoted changer member (1) for at least two yarn transfer elements (2) each in the form of a slide rod (2a) and a yarn gripper (21). Slide bars for the yarn transfer elements (2) are provided on the changer member (1) and are connected by at least one lightweight plastics holder to a tube effective as a drive shaft of the changer member or as a pivot spindle. The inventive weft yarn changer yields reduced actuation times.

Abstract: A positive eccentric dobby having a rigidly mounted roller lever shaft with minimal clearance, on which pivoted roller levers are disposed, which transmit the movement to the heald frames via coupled connecting rods, reversing levers and rods. A camshaft with eccentrically disposed cam discs is rigidly mounted on a displaceable carriage. In the state where there is a clearance between the rollers and the cam discs, one or more stops swivel the roller levers so that the heald shafts can be coordinated in several preset positions. When there is no clearance between rollers and cam discs, a jamming block having a motorized driving device fixes the position of the carriage with a stop.

Abstract: The lubricant mist is supplied in timed fashion to at least one nozzle (31, 36, 40, 45) associated with a lubrication station in the zone of movement of a moving part (32, 37, 41 and 34 respectively). The timed supply of the mist is effected in dependence upon the position of a drive shaft from which the moving part derives its movement. The lubricant mist can therefore be supplied to the lubrication station in an accurately dosed quantity only when it is needed there. A possible use of the lubricating method is for looms where it is particularly important that the web of cloth produced on the loom should not be soiled by lubricant.

Abstract: The weft break stop motion (1) detects without contact a potential displacement in the feeler (5a) effected by a weft thread moving past by means of a plate-like layered sensor element (2). With the feeler (5a) turned towards the weft thread insertion, the sensor element (2) can be introduced between the drop wires (23) of the reed (18). The weft break stop motion (1) and the sensor element (2) can be variably positioned along the reed (18), depending on the screen of the drop wires (23), and is normally placed directly outside the warp threads according to the loom width.

Abstract: Between the supply bobbin and a thread tensioner supplied therefrom, which comprises a thread guide (12) which can rotate around an axis of rotation (11), are disposed a fixed thread guiding component (3) and an optical sensor (20) for monitoring the weft thread (2), which is guided by the sensor (20) and an inlet channel (18), which passes through the thread guide (12) in the axial direction, towards the thread tensioner (5). The inlet channel (18) of the thread guide (12) is eccentrically offset with respect to its axis of rotation (11), so that the section of the weft thread (2) running towards it is laterally deflected and a rotational movement which can be detected by the sensor (20) is imparted to this section, and enables a safe monitoring of the weft thread (2) with minimal thread tension. A guide piece which has a guide channel eccentrically disposed with respect to the axis of rotation (11) and can be mounted on the thread guide (12) may also be provided as means to deflect the weft thread (2).

Abstract: The weft yarn clearing device is of use for an automatic method of clearing weft breakages in projectile looms. In the event of the yarn breakage in the shed, the weft yarn is engaged in the shed by at least one gripper element, then supplied to the inlet of an extractor and placed between the rollers of a pair of draw-off rollers. The rollers draw the weft yarn out of the shed and the weft yarn is simultaneously supplied by the extractor to a collecting receptacle. The clearing device can also be used for a yarn breakage before the shed.

Abstract: The stem of the femoral prosthesis is provided with a slot in the medial narrow side which communicates with a through-bore within the stem adjacent to the collar. In addition, an elastomeric filling is disposed within the through-bore and cooperates with an arch which connects the proximal end of the stem to the collar or neck in order to adapt the resilience of the stem in the proximal zone to the resilience of the cortical bone. The filling may be made of polyurethane or silicone material.

Abstract: The knee joint prosthesis is formed of a tibia metal plate which can be attached to a tibia and a femur part which can be secured in a femur. An intermediate plastic part is provided on the tibia metal plate to receive the femur part in bearing relation. In order to reduce abrasion of the intermediate plastic part, support members of hard material are distributed in the bearing surface of the intermediate plastic part to receive the femur part thereon. The bearing surfaces of the support members are integrated in the bearing surface of the intermediate part and are provided with dual surfaces to receive different bearing surfaces of the femur part, each of which has a different radius of curvature.

Abstract: The implant may be used as prosthetic replacement for a ligament and/or tendon. The implant has a plurality of discrete longitudinal strands disposed in side-by-side relation with transverse filaments about the strands. Individual sub-zones of the ligament are folded over in a transverse manner about a longitudinal axis of the sub-zone with intermediate zones being in an unfolded state. The intermediate zones may be formed solely of longitudinal strands to enhance flexibility.

Abstract: The shank for a femur head prosthesis is provided with a cavity in the approximate region which is filled with a plastic or elastic filler. A covering is provided over the filler to avoid contact between the filler and the bone or the bone cement surrounding the shank. The covering reduces the area of contact between the bone the filler to a minimum and limits the "flow" of the filler under compressive loadings on the head of the prosthesis.

Abstract: A series-shed loom with a weaving rotor (1) and laying-in members (2) which lay the warp threads (3) into high points and low points on the weaving rotor (1) to form the sheds, while the weaving rotor combs through the sheds (6) so formed to beat-up against a beater bar (8) of a meanwhile inserted weft yarn (7). Warp threads (3a, 3b) are laid into gaps (11) in the combs, while the low points (5) of one warp thread (3) are formed in gaps (11) which are in line in the direction of rotation (9). The high points (4) for one warp thread (3a, 3b) are formed by fins (12) which are in line in the direction of rotation and which form longitudinal saddles (13a, 13b) extending in the direction of rotation (9) between a beater nose (14) and a holder nose (15).

Abstract: The picking mechanism has a torsion rod whose zero position is adjustable by an adjusting lever and an adjusting drive. A rigid wedge-shaped intermediate member movable by the adjusting drive is disposed between a sliding surface of the adjusting lever and a stationary sliding surface. Movement of the intermediate member produces a pivoting movement of the adjusting lever to alter the zero position. The intermediate member transfers a force exerted by the adjusting lever on to the stationary sliding surface.

Abstract: A weft yarn changer on a projectile loom has a pivoted changer member (1) for at least two yarn transfer elements (2) each in the form of a slide rod (2a) and a yarn gripper (21). The slide rod (2a) is made of plastic and is longer radially than tangentially in the pivoting direction relative to the pivoting axis. A duct (24) oriented in the sliding direction forms a cavity which is particularly suitable as a yarn guide. The inventive yarn changer has short actuation times.

Abstract: To secure a cloth beam (2 ) of a loom in an open bearing shell (6) a resiliently borne tongue (7)is provided. The tongue includes a nosing (11) between two arms (10, 12) and is connected at one end of the first arm (10) to a bearing table (5). The nosing (11) secures a cloth beam journal (4) in the bearing. When the tongue (7) is pivoted by a lever (14) on the second arm (12) of the tongue (7), the nosing (11) moves away from the shell (6) so that the journal (4) can be moved out of the shell. Satisfactory securing of the journal (4) is therefore provided and the cloth beam (2) can be changed readily without the use of tools.
