Abstract: A method of inserting a rigid plastic lining tube into a conduit wherein a rigid plastic tube wound in a flatly folded state around a drum is inserted into a conduit as the plastic tube is pulled out of the drum, comprises the steps of supplying a heated fluid into the conduit so that the heated fluid flows from one end opening of the conduit to the other, and heating the whole of the inner circumferential surface of the plastic tube with this heating fluid flowing through the conduit, to sof­ten the same tube. According to the present invention, the plastic tube can be softened with heat uniformly along the whole length thereof with the plastic tube kept in a drum-wound state, and it can also be maintained in a thermally softened state even while the tube is inserted into the conduit. The insertion of the rigid plastic tube into the conduit can be carried out with a high efficiency. Moreover, even when the conduit has a bent portion at an intermediate part thereof, the plastic tube can be inserted thereinto as it is passed through the bent portion easily.

Abstract: Disclosed are spiral-wound membrane cartridge constructions (10) for use in ultrafiltration and reverse-osmosis separation equipment, each of which include a feed layer (16), a membrane layer (14) and a permeate carrier layer (12). By using a feed layer (16) in the form of a channel material having a plurality of parallel ribs (50) extending in an axial direction, interconnected by a matrix of smaller filaments (52) which may be generally perpendicular thereto, this construction advantageously reduces resistance to liquid flow axially through the cartridge (10), registering only very low pressure drops. Such cartridges of 40 to 70 inches in length and 8 inches in diameter may be employed in series, even within a single outer casing or pressure vessel. Such constructions are especially useful in separating liquids having high levels of particulate contamination using ultrafiltration membranes where clogging of the cartridge is a common problem and also in concentrating solutions of fairly viscous water-soluble polymers.

Abstract: Alumina powder, e.g. ≦ 5 µm diameter, and carbon powder, preferably acetylene black eg. ≦ 1 µm, are admixed, e.g. in an aqueous slurry followed by drying; the carbon is present in molar excess, preferably the C:Al₂O₃ ratio is 3-10:1. The mixture is heated in a nitrogen atmosphere at 1500-1700°C for 2-10 hours to make aluminium nitride. 
     To remove excess C, the product is further heated in air at 600-750°C, before or after being pulverized, to a BET specific surface area ≦ 6 m² to contain not more than 50% of powder < 1 µm diameter, preferably in dry air or N. Thus a powder of a tapped density  1.0. /cm³ is obtained. There may then be added 0.01-10 wt % of a sintering aid and 0.05-2 wt % of an oleophilic dispersant, to give a powder containing 0.05-10% of the sintering aid and having an oleophilic surface. 
     The apparatus used should be non-metallic. A product of low Fe, Si and Ti impurity content is thus obtained and which can be sintered satisfactorily to make pore-free bodies of high thermal conductivity.

Abstract: A semiconductor layer (11, 12a, 12b, 13) undergoes isolation etching and gate recess etching, using a side wall insulating layer having the shape of a forward taper as a mask, by means of the anisotropic etching technique. The shape of the side wall of the semiconductor layer (11, 12a, 12b, 13) corresponds to that of the forward taper of the mask. The shape of the forward taper is always constant, irrespective of face orientation of crystal of the semiconductor layer (11, 12a, 12b, 13). Since the taper angle of the side wall insulating layer (14b1; 14d1) can freely be set within a predetermined range in accordance with conditions, the taper angle of the semiconductor layer (11, 12a, 12b, 13) can be controlled. The design margin of an electrode wiring pattern is greatly improved. Since the side wall (14e) of a gate recess is stably formed in the shape of a forward taper, the side wall insulating layer (14e1) can be formed on the surface of the forward taper and thus a gate electrode layer (17c) can be formed so as to have a T-shaped cross section. Therefore, the gate resistance can be greatly reduced.

Abstract: The invention relates to a method and an apparatus for measuring the radioactivity of samples that are arranged in the wells of a microtitre plate and in which the radio-activity is solid-bound, for example cell-bound, or is in the form of a protein precipitate, wherein samples suspended, dissolved or mixed in liquids are first separated from the liquids and then their liquid supernatant is removed by suction. The invention comprises connecting the bases (4) of the wells of the microtitre plate to one another and then separating them from the microtitre plate or the well walls in such a manner that they remain connected, and subsequently measuring the samples they carry in succession, in groups or simultaneously over the entire grid. Thus, the well bases (4) can be handled and prepared for the measurement of radioactivity in their original position and arrangement even after separation from the rest of the microtitre plate, it being possible to bring the bases (4), which have been separated from the microtitre plate, and the samples arranged thereon close to, and within touching distance of, the measuring apparatus. As a result, a high degree of sensitivity and spatial resolution can be achieved, even in the case of samples of which the emitted electron radiation has only a very small range.
