Title: Sewing machine with increased machine speed - has horizontal drive to needle bar and spool mechanism synchronised to follow cloth advance mechanism in any direction
Inventor: IWATA MASANARI
IPC: D05B3/02
Filed: 1990-11-15
Abstract: A sewing machine is constructed to include a work table with a sewing head. The drive from a motor is transmitted to a vertical movement for the needle bar and a revolving motion for the spool mechanism.

Title: Semiconductor structure with metal corrosion prevention - by insulation layer between metallisation and barrier layer
Inventor: ISERNHAGEN RUDOLF DIPL PHYS DR
IPC: H01L23/532
Filed: 1990-11-30
Abstract: (A) In a semiconductor structure with a silicide layer (5) a barrier layer (6) and a metallisation (9') the novelty comprises provision of an insulating layer (8) in the side surface region of the barrier layer and the metallisation. The insulating layer may be of polyimide, SiO2 or Si3N4. (B) Prodn. of the structure, in which a semiconductor region is contaced via a silicide layer and in which a diffusion barrier layer is produced between the silicide layer and the contacting metal, involves applying an insulation layer after structuring the barrier layer and then structuring the insulation layer to form a contact opening in the contacting region. The insulation layer extends over the barrier layer sufficiently to separate the subsequently applied metal electrodes or metallisation from the barrier layer in the side surface region. ADVANTAGE - The insulation layer prevents migration of impurities (e.g, Cl contamination when etching the metallisation using a Cl-contg. plasma) to the barrier/metallisation interface and thus prevents corrosion of the metallisation.

Title: Fabric pile edge detection - uses angled light bundles across fabric for video camera to register edge position
Inventor: EISEN JUERGEN
IPC: B65H23/02
Filed: 1991-09-20
Abstract: Assembly to register the position of the edge (2) of surface piles on a moving fabric (1), where the pile thickness abruptly changes, has at least two light radiators (41, 42) over the fabric (1) on both sides of the pile edge (2). Each delivers a light bundle (7) to strike the fabric (1) at the pile edge zone, with a light bundle cross-section across the direction of material travel. The light bundles are opposed to each other, on a parallel projection to the direction of travel, at an equal large angle (6) to the fabric plane. At least one video camera (8) registers the edge zone of the fabric (1) alternately from the light of one source or the other (41, 42). The image signals from the camera (8) are stored for one image and the other. The stored image signals, if necessary after signal processing, are passed to a computer and subtracted from each other so that the signal difference gives the pile edge location. ADVANTAGE - The position of the pile edge can be established opto-electrically, without deflecting the fabric in the scanning zone.

Inventor: KLEMPS ROBERT DR
IPC: C05F17/00
Filed: 1991-12-11
Abstract: The soiled ground material is mixed with organic residue from (an)aerobic composting at 10-40%, using the coarse grain fraction from a sieve action.

Title: Internal combustion engine with by-passed exhaust turbo-supercharger - has jointly controlled and pref. pneumatically operated rotary closure flaps in compressor by=pass and turbine outlet.
Inventor: KARCH ERNST
IPC: F02B37/22
Filed: 1992-01-13
Abstract: The compressor unit (12.1) of the supercharger (12) draws air through an inlet pipe (16) equipped with a filter (14), and drives compressed air (18) into the engine (10). It is bypassed by a passage (26) contg. a slider (28) for opening and closing. The exhaust gas (19) drives the turbine (12.2) from which it passes to atmosphere (20) unless throttled by another slider (22). When this is closed the bypass is opened (24) allowing free intake of air for engine braking. USE/ADVANTAGE - Esp. in diesel power plants, optimal engine braking is guaranteed when the slider in the final exhaust pipe is actuated for closure.
