Abstract: Connection is effected by piercing the insulation of the cable by of a pair of needles (36) connected to the circuit and disposed parallel to one another at a distance slightly less than the diameter of the central conductor (19) of the cable, so as to come into contact with the conductor at two diametrically opposed regions. The parts of the needles which pass through the screening braid (21) of the cable are covered with insulation (44).Two other pairs of parallel needles (52) are disposed symmetrically either side of the first pair and are arranged in pairs at a distance corresponding to the diameter of the screening braid. All the needles are disposed on a jaw (15) adapted to receive the cable, against which a second jaw is closed when actuated by a two-position lever. This is connected to the second jaw by connecting rods which in the closed position are moved beyond a dead point.According to a modification, the spacing of the needles (36) is kept constant by a guide cylinder, which slides axially on the needles and is urged by a spring to a position such that it guides the needles in the vicinity of the cable. The connection device is incorporated in a transceiver which is to be connected to the cable of a data transmission local area network.

Abstract: The body 23 of a rotary drill bit is formed from a matrix formed by a powder metallurgy process, and a plurality of cutting elements 14 are mounted on the bit body, each cutting element being in the form of a disc of superhard material which is thermally stable at the temperature of formation of the matrix. The front surface of each cutting element is engaged by a holding structure 22 on the bit body in front of the cutting element 14, the arrangement of the holding structure being such that the resistance provided by the holding structure to forward deflection of the portion of the cutting element opposite the cutting edge 25 is less than the resistance to rearward deflection provided by the surface behind the cutting edge. Bending stresses imparted to the cutting element 14 by rearward deflection thereof in the vicinity of the cutting edge 25 are thereby reduced.

Abstract: One or more monolayers of cerium arrayed on the surface of a niobium metal acts as a catalyst to oxidation of the niobium at ambient temperature and results in a very thin, very high quality insulating layer which may be configured by patterning of the catalyst. Significant amounts of Nb<sub>2</sub>0<sub>5</sub> are formed at pressures as low as 6.6x 10<sup>-6</sup>Pa, promoted by thepresence of the cerium. This catalytic activity is related to the trivalent to tetravalent valence change of the cerium during oxidation. The kinestics of Nb<sub>2</sub>0<sub>5</sub> formation beneath the oxidation cerium shows two stages:the first stage is fast growth limited by ion diffusion;the second stage is slow growth limited by electron tunnelling.Other catalytic rare earths usable instead of cerium are terbium and praseodymium; other substrate materials usable instead of niobium are aluminium, hafnium, silicon and tantalum, or oxidizable alloys thereof.

Abstract: The suction apparatus (36, 37), in particular for sucking in foam polystyrene chips, has a lid-shaped connection fastening (3) on the bearing arm (10) of a stand (2) for a collection bag. The connection fastening is provided with a covering edge (23), which is closed at the top front end, for sealed-off covering of the bag edge. Directed downwards and opening out into said connection fastening is a blower opening (26) of a conveying channel (4) which is connected to the outlet (8) of a conveying fan (5). The blower opening (26) is covered by a dust filter so that rapid filling of the storage container is achieved with very smooth running, high conveying capacity and without dust. Opening out into the separation chamber (39) of a connectable individual suction apparatus (36) is an inlet opening (46) for the packing material, which is mixed with foreign constituents, and an outlet opening (37) for the separated packing material. These two openings lie adjacently opposite a housing door (58) and the front side is formed by a viewing window (60). The bottom is formed by an accumulation and collecting device (55). Thus the foreign constituents sucked in with the packing material can be separated at a high operating speed and in an extremely simple manner and can then be removed. <IMAGE>
