Patent EP-0087135-B1 (EP)
IPC: C23C18/28
Filed: 1983-02-18
Granted: 1986-11-12
Abstract: A catalytically active powder, its preparation, and its use for activating insulating substrates to receive electrolessly deposited metal in a coherent metal layer are described. The powder of the invention comprises a plastic powder containing catalyzing/activating chemical compounds allowing that the acceleration of the catalyst is not carried out until the powder is melted down onto the substrate. The substrate need not be etched prior to the metallization since the plastic melted down ensures a good adhesion between metal and plastics and between plastics and substrate. Furthermore, the colloidal nature of the catalyzing compounds is stabilized in a particular and especially durable manner by the plastic powder. The use of the powder causes less risk to the environment since the catalyst may be applied as a dry powder, and since the etching of the substrate is avoided.

Title: Implement for working agriculturally utilized soil
IPC: A01C23/02
Filed: 1983-10-11
Granted: 1988-12-28
Abstract: Disclosed is a process employed for loosening agriculturally used soil, particularly for the in-depth loosening of compacted soil by injecting air into the soil. To do so, a probe is pulled through the soil continuously in direction substantially parallel to its surface. While the probe is being conveyed through the soil by way of a tractor, for example, compressed air is abruptly released at intervals in eruptive bursts so that soil loosening is achieved in a continuous operational flow.

Abstract: A compensator for providing resilience in a connection between relatively moveable objects comprises a piston (3) working in a cylinder (2) which is surrounded by a larger coaxial cylinder (1) joined thereto by annular wall members (1a) thus defining about the cylinder (2) a pair of annular reservoirs (8, 9,) The piston (3) divides the cylinder (2) into a pair of chambers (6, 7), chamber (6) being connected by conduit (12) to reservoir (9) and chamber (7) being connected by conduit (10) to reservoir (8). Each reservoir contains a mixture of liquid and gas whilst the chambers contain liquid. Elongation of the connection between the objects causes withdrawal of the piston (3) with consequent expansion of the volume of gas in reservoir (9) against atmospheric pressure and against pressure developed in reservoir (8) as a consequence of decrease of gas volume therein.

Abstract: Apparatus (10) for hydraulically separating a mixture of small size mineral particles according to different mineral densities includes principally, an inclined tubular conduit (11). The inclined conduit (11) has a bottom surface (19a) extending axially along the conduit (11) that is tilted in a second direction relative to the direction of inclination of the conduit (11); so that the bottom surface (19a) forms a low-point line (12) extending throughout the conduit (11). An upward fluid flow through the conduit (12) for processing is adjusted to move the light mineral particles (61) in upward direction by effects of the higher midstream fluid flow velocity forces, while the conduit surface effects allow the heavy mineral particles (91) to accumulate along the low-point line (12) and to move in downward direction during processing by the inherent lower fluid flow velocity forces along the conduit boundary or wall surfaces.

Abstract: In a transmission network have a tree structure in which data is forwarded from the tree branches toward the trunk at periodic intervals, the data which is transmitted between the several network levels is reduced by deleting data corresponding to a predetermined information content corresponding to the most probable configuration of such data. The remaining data is divided into sub-sets and transmitted with an individual sub-address for each sub-set, and a control signal identifying the number of sub-sets which are transmitted, and an address identifying the sending station. Optionally, when more than half of the sub-sets contain information not corresponding to the predetermined information, the data blocks are transmitted without sub-addresses but with a control block which identifies a mode in which all sub-sets are transmitted without sub-addresses.

Abstract: Sensing arrangements on material rolls are used to give advance warning when the material web forming the roll approaches its end. Usually this involves the sensing of the reduction of the roll diameter with the help of a sensing device resting against the roll periphery. In the case of roll suspensions where the centre of the roll is not fixed, these sensing arrangements cannot be used. Here it is possible instead to use a sensing arrangement which comprises a field-generating element (11), e.g. a permanent magnet, present in the centre of the roll (3), together with a movable sensing device (8) resting against the periphery of the roll, e.g. a heavy current switch which is acted upon at a certain predetermined field strength, and in a suitable manner indicates that a roll replacement is imminent.

Abstract: A nonclogging rotary disk filter (10) is disclosed. The invention has relief holes (60) provided in rotatable disks (11) such that oil, other liquids, and gases may be separated from a liquid while the disks (11) are rotated at high speeds. The relief holes (60) are located close to the rotatable shaft (12) supporting the disks (11). When the disks (11) are rotated at high speeds, lighter liquids, oil, and gas bubbles tend to migrate to the area near the shaft (12) which has relatively low centrifugal forces. In a gravitational field, the relief holes (60) allow the lighter liquids, oil, and gas bubbles to migrate upwardly through the disks (11) for removal. The disks (11) are rotated fast enough to establish a barrier layer (28) in a liquid over a working area (67) of the disk surface having a surface velocity greater than 15 feet per second.
