Abstract: ABSTRACT OF THE INVENTION     An electromagnetic thickness tool is disclosed to produce a measurement of the wall-thickness of a ferromagnetic casing corrected for the effects of casing permeability.  First apparatus provides an uncorrected thickness signal proportional to the thickness of the casing uncorrected for the effects of casing permeability.  A second apparatus provides a permeability signal representative of the permeability of the casing.  A signal processor uses the mathematical square root of the permeability signal as a correction factor for the uncorrected thickness signal for generating the corrected value.  The second apparatus, responsive to a signal proportional to the magnitude of the inside diameter of the casing, corrects the permeability signal for the effects of casing inside diameter.

Abstract: A B S T R A C T           The present invention relates to propellant powders based on nitrocellulose, nitrated oil and poly-vinyl nitrate and also to the process for their manu-facture.          The powders according to the invention contain between 50 and 75 parts by weight of nitrocellulose, between 5 and 25 parts by weight of nitrated oil and between 5 and 25 parts by weight of polyvinyl nitrate.          The manufacturing process consists in malax-ating the energy-producing bases in the presence of an acetone/alcohol mixture until a homogeneous paste is obtained, which is extruded, drained, chopped, soaked and dried, and the process is characterized in that (i)  the proportion of acetone in the paste during malaxation is between 30 and 36% by weight, relative to the dry nitrocellulose and the dry polyvinyl nitrate, and in that the weight ratio acetone/alcohol is between 1.10 and 1.50, (ii) the first step is to mix the nitro-cellulose with the nitrated oil in the presence of solvents, and in that the solid polyvinyl nitrate is added to the mixture in portions, and (iii)  the draining before chopping is carried out at a temperature below 30°C.          The powders according to the invention are particularly suitable as gunpowder for combat tanks.

Abstract: ABSTRACT OF THE DISCLOSURE         The method comprises providing an extremely strong and elastic alloy steel ring having an inner diameter substantially smaller than the out-er diameter of the pipe to be joined, and an outer diameter much larger than such outer diameter of the pipe.  Great axial forces are then employed to in-sert the pipe ends into the ring until an internal flange is abutted, thus stretching the ring without causing it to exceed its elastic limit.  End seals are provided on the flange faces and are pinched off by the pipe ends, so that metal-to-metal contact results.  Prior to forcing the pipe ends into the ring, it is mounted in an internal groove in a hinged clasp which aligns the pipe ends.  The apparatus comprises the ring, the clasp and the seals, and further comprises the completed joint wherein the ring is under continuous great hoop stress.

Abstract: ABSTRACT OF THE DISCLOSURE          A bi-leaflet heart valve wherein two complementary leaflets open and close a passageway of generally circular cross section through an annular valve body.  Each of the leaflets is pivoted by interengaging means at opposite locations on the annular valve body.  The valve body is provided with arcuate seat means having a downstream facing surface, and the leaflets are formed with a major arcuate edge which seals against the interior surface of the valve body and with a planar minor edge.  In the closed position, the upstream surface of the leaflets lies in abutting contact with the downstream surface of the seat, and the planar surfaces abut each other along a plane diametric of the passageway, thus positively closing the center. The proportioning of the leaflets and the location of the seats are such that the load on the interengaging means is relieved in the closed position, wherein the load is supported primarily by the contact between the leaflets and the seat.

Abstract: The invention relates to a device in a machine for trimming vegetables, especially Brussels sprouts, by means of a rotary cutter forming the bottom of a trapezoidal groove (3), which is formed by the inclined sides (2) of a pair of rotary flanges, the vegetables being caused by the action of the rotary flanges and stationary holding means (5-12) to perform a rotary movement around themselves at the same time as they follow the rotary flanges in the groove (3) between them, and projecting parts of the vegetables are exposed to the cutter and trimmed off. According to the invention the holding means consists of a number of substantially planar plates (5-12), which are arranged resiliently and elastically pivotable around axes (13-20), which are substantially parallel to the rotary shaft of the cutter and of the flanges, which overlap each other like roof tiles substantially along the groove (3) between the flanges with the free ends of the plates pointing in the direction of rotation, and which form a ceiling of the groove along a part thereof (FIG. 1).

Abstract: ABSTRACT OF THE DISCLOSURE      A series of equally spaced holes are formed in a slide fastener stringer tape including synthetic fiber by thrusting and melting away tape portions spaced along a marginal edge of the tape on and between an ultrasonically vibrating horn and an endless series of anvil teeth successively pressable against the horn.  The stringer tape is then moved away from the horn so as to be cooled for thereby setting the holes.  Thereafter, a series of coupling elements are injection-molded onto the stringer tape over the holes. The advance in the art is in that by using solely the melting-away procedure, the holes are dimensionally stable.  The threads are prevented from fraying in the holes, with the resulting improved anchoring of the elements on the tape.

Abstract: ABSTRACT         The invention relates to multi-strand cables, the wires of which are already prepared in the factory in such a way that the cable splice can be carried out on site in a time-saving manner.          This concerns, in particular, the ordered forming out and fixing of the individual wires.  Fixing of the individual wires (1) occurs in flexible, inelastic holders (2a, 2b, 44, 50, 51, 52), whereby the arrangement according to the invention is chosen such that they can be fixed to the cable end in as space-saving a manner as possible.  According to the invention, a cable prepared in such a way with its wires prepared and fixed at the end must be capable of being inserted in this condition into the cable conduit installation, so that after inserting the cable all preparations for splicing have already been made.  This has considerable advantages over the methods hitherto common since the preparation, forming out and fixing of the individual wires in the factory can be carried out with much greater certainty than at the assembly site.  With the methods hitherto common the cables are first of all inserted into the cable conduit installation and only then is the preparation work for producing the splice started.

The detonators are electric-ally coupled to the looped wire by means of slidable toroidal transformer cores.  The wire loop, in turn, is electromagnetically energized by means of a second trans-former core and an energy source.  The method provides for safe and efficient borehole charging and avoids the hazards associated with usual electric detonator systems.

Abstract: TITLE OF INVENTION     CHIP-FREE STAPLE FIBER PROCESS     ABSTRACT OF THE DISCLOSURE     An equilibrium melt from a standard hydrolytic or anionic polymerization of caprolactam is spun at a temperature between about 230 and 270°c through a spinnerette, preferably one having a multiplicity of holes spaced from each other in an asymmetric arrangement, the spinning take-away speed being less than about 250 meters/minute.  The molten strands of polycaprolactam are quenched in two phases: (1) gas at a temperature of less than 20°c is directed from a first entrance in a crosscurrent flow upon the face of the spinnerette and upon the molten polycaprolactam strands immediately adjacent thereto, and is exhausted adjacent to the back of the spinnerette; and (2) gas at a temperature of less than 20°c is directed in a countercurrent flow from a second entrance downstream from the first entrance with respect to the direction of movement of the polycaprolactam strands; whereby the surface temperature of the polycaprolactam strands is reduced to 30-70°c.  A drawing and crimping lubricant and antistatic agent is then applied to the surface of the polycaprolactam strands which are then drawn at a total draw ratio between 3 and 5.  The polycaprolactam strands are then crimped and cut into staple lengths, which are subsequently washed in multiple stages, dried, and packaged for subsequent use or sale.
