Title: Rail guided trolley for production flowlines, etc. - is of U=section, fitting over I=section rail with drive wheels on one side and contacts to electrical services on other
Inventor: LUECK JOCHEN DR ING
IPC: B61C13/04
Filed: 1990-10-18
Abstract: The trolley (10,10A) is of U-section and runs on an I-section rail (2) which is supported (1,8) at a convenient working height from the floor. On one side leading and trailing wheels (12) and an opposing roller (15) run on the inner flange surfaces of the rail. The wheels (12) are driven from a motor unit (11), the drive being taken from a pinion (14) onto gears (13) co-axial with the wheels (12). Eight guide rollers, four top and bottom, ride on the outer edges of the rail flanges and provide constraint against tipping under load. On the side opposite to that of the trolley drive wheels the space between the rail flanges is used to house conductors and sliding contacts for electrical services. One trolley may be coupled to another by means of a pivoted bar (28). In this case a drive is required only on one trolley. ADVANTAGE - Requires only narrow track. Can accommodate wide load without tipping. Can traverse bends and slopes.

Title: Feed chute dispensing fibre into baling press - has limited switch in dispensing fork drive to adjust starting distance of fork from chute exit
IPC: A01F15/10
Filed: 1990-11-20
Abstract: A row of prongs (6) across the exit (4) of a feed chute (3) controls the dispensing of fibre into the channel (1) of a baling press.

Patent DE-4120945-A1 (DE)
Inventor: TISCHBEIN CLAUS
IPC: D06B3/12
Filed: 1991-06-25
Abstract: In a wet-treatment installation for continuously running textile webs which works by double loop entry, interior upper and lower rollers are arranged, as is known per se, between exterior upper and lower rollers in the treatment compartments, so that the fabric follows a zig zag-shaped inner loop on its way from an exterior upper roller to the corresponding exterior lower roller. The interior upper and lower rollers have a smaller diameter than the exterior upper and lower rollers. Only the exterior lower rollers dip into the treatment fluid. According to the invention, a collecting and diverting plate (22) is arranged respectively between an exterior upper roller (18) and the associated interior upper roller (19). The excess treatment fluid adhering to the fabric web (26) is thereby guided in a controlled manner into the inner loop and therefore utilised more effectively than in known installations. The collecting and diverting plate (22) is mounted adjustably, so that it touches or does not touch the fabric web selectively. <IMAGE>

Title: Testing polystyrene medical tubes using automatic layout - by passing them through suitable e.g. illuminating field so that inhomogeneities affect detectors and trigger e.g. ejector
Inventor: BABST ULRICH DIPL PHYS
IPC: G01N21/954
Filed: 1991-08-30
Abstract: Small reagent tubes of polystyrene are tested for faults after their production by placing them vertically or horizontally on a conveyor and moving this at a set speed into an optically irradiating system on a head fitted with one or more detectors, illuminating them, detecting any faults by a conventional process with transmitted or scattered light, dark ground or optical inhomogeneities, and rejecting in the event of a threshold level on individual photodetectors. ADVANTAGE - The procedure is a fully automatic quality control. It is suitable for use with diagnostics in medical laboratories (e.g. testing reactions with blood serum). In an example, the transparent polystyrene tubes (100) are passed through a field where a low light transmission is detected normally but e.g. scratches or cracks, etc. scatter light. Each tube (100) is passed by the head (10) and a light source (14) with lens (17) and (e.g.) filter (19) plus aperture (15). One or more detectors (11,12) are arranged on one side; only light scattered by a fault (101) reaches one or more detectors (12). This triggers off a suitable ejector device. Suitable sensor arrays can also be used alternatively.
