Title: Tubular chuck for holding round bar - has row of interlocking spherical rings with tongue extensions which grip workpiece
IPC: B23B13/12
Filed: 1977-07-28
Abstract: A chuck for gripping round bars or tubes consists of an outer tube (10) which houses a number of rings (30, 40). The rings have spherical outer surfaces and pivot inside the tube on two diametrically opposite bolts (34). These rings also have two diametrically opposite tongues (32) aligned at right angles to the bolts and projecting in axially opposite directions. The rings (40) have cylindrical outer surfaces with a single tongue (42) and are attached by screws through slots in the wall of the tube to a rod. The rod is moved axially by a pair of nuts screwed on the end of the tube. This axial movement of the rod brings each cylindrical ring closer to its neighbouring spherical ring, causing it to rotate about the pivot so that the tongues grip the internal bar.

Abstract: The cell includes a solid electrolyte separating sodium from the cathodic reactant in which is located a current collector. The latter comprises a core of a first metal having a coating chemically and electrically inert to the reactant. Bonded to the core through the coating, and in electrical contact with the core are one or more elements of a second metal which is, or is coated with, a conductive material which is, chemically and electrochemically resistant to attack by the reactant. Preferably the core is Al with a coating of Al2O3 or of Ni; the second metal may be Ni, Ti, Mo, stainless steel or Ni-Cr alloy. The second metal may be a sleeve, or may take the form of radially projecting fins. The invention is of particular use in vehicle batteries where it is necessary to draw heavy currents. The collector provides low internal resistance while affording good resistance to attack by the reactant.

Patent NL-8104664-A (NL)
Title: Heat exchanger tube stack plate - is sealingly secured in exchanger vessel independently of tube inlet chest and vessel end cover
IPC: F28F9/02
Filed: 1981-10-14
Abstract: Heat exchanger comprises a cylindrical vessel (2) with access opening and cover at one (RH) end, and a tube plate (12) with (U-shaped) tube stack insertable via this opening and resting on a collar (10) in the vessel via resilient packing (11). This plate separates a space around the tube stack with inlet and outlet connections from a space containing a chest (39-42, 44, 47) which separates inlet (20) and outlet for the medium passing through the tubes. The plate (12) is pressurised against the packing by circumferentially spaced axial bolts (30) in screw bores (29) through a mounting ring releasably held (26) in (an annular groove 23 in) the vessel wall (2). This ring is in at least three parts whilst the chest connects (via 41,38,31; 42,37,35) with the plate (12) radially inwards of the ring (24) and can be assembled and dismantled independently of this ring. The arrangement facilitates access for assembly and dismantling of the plate (12) with tube stack and maximises the plate area available for tubes. The sealing (11) pressure is applied independently of the end cover fixture so that the tube space can be pressure-tested before fitting the chest and end cover. The mounting (24) (and pressure 31) ring assembly has a short axial length which minimises differential expansion. Such expansion can be easily absorbed by using a resilient packing (11).

Title: Pressure transducer using fibre=optic techniques - uses pressure changes causing distortion of fibre optic coil and changing light transmission characteristics
IPC: G01L9/00
Filed: 1984-01-09
Abstract: A thin-walled tube (1) has a closed upper end (2) and an open lower end for connection (3) to a pressure source. The central section of the tube has longitudinal grooves which form ribs along much of its length. An optical fibre is wound several times around the tube. Changes in pressure and hence in tube cross-section result in proportional changes in light transmission between a light source and a detector at the other end of the fibre. Variants which have a sealed housing around the tube and fibre enable differential pressure measurements.

Title: Expanded porous granular ceramic prodn. - from bleaching earth esp. waste by mixing with carbonaceous material, pressing, granulating and calcining
IPC: C04B18/04
Filed: 1987-07-15
Abstract: Conversion of bleaching earth (I) to expanded porous ceramic granules (II) involves mixing (I) with organic material (III), which is carbonised at ca. 400-700 deg.C; pressing the mixt. to cakes; granulating these; and calcining the granules. Pref. (III) consists of cellulosic material, e.g. wood and wood fibres, or organic fuel, e.g. diesel oil. (I) is lean, scoured (I). (III) is added in an amt. of 0.1-25, pref. 0.5-15 wt.%. Fat (I) pref. is added to a cake of lean scoured (I), pref. in an amt. of 10-30, esp. 15-25 wt.%; and lime may also be added. The granules have a dia. of 1-50, pref. 4-25 mm. They are dried before calcination, pref. for 10-20 min. at 70-100 deg.C, then calcined 5-20 min. at 500-800 deg.C, pref. 8-15 min. 600-700 deg.C and then opt. sintered at 1000-1300, pref. 1000-1100 deg.C. Waste (I) from purificn. and bleaching of mineral and vegetable oils, fats and waxes can be converted to environmentally harmless, useful (II), rather than requiring disposal in special dumps. The process is esp. useful in conjunction with a process for scouring fat (I) by boiling, since the energy generated (esp. if fat (I) is used) at least partly covers the energy requirement of the boiling process.
Patent NL-8801207-A (NL)
IPC: H04N7/30
Filed: 1988-05-09
Abstract: In a television transmission system for digital picture signals each picture is divided into sub-pictures of N x N picture elements for the purpose of limiting the bit rate. Each sub-picture is subjected to a two-dimensional forward transform to determine coefficients. These coefficients are converted into a series of serially occurring coefficients in which the AC coefficients in this series are arranged in such a way that the magnitude variation of these AC coefficients in the series is monotonous. The magnitudes of the AC coefficients thus arranged are subjected to a differential encoding so that the difference between the magnitudes of two successive AC coefficients is transmitted instead of the magnitude of the AC coefficients themselves.

Title: Method and apparatus for adjusting a digital equalizing filter in simultaneous adaptive echo elimination and adaptive elimination of noise caused by intersymbol interference
IPC: H04B/
Filed: 1986-04-21
Abstract: PCT No. PCT/SE86/00162 Sec. 371 Date Dec. 12, 1986 Sec. 102(e) Date Dec. 12, 1986 PCT Filed Apr. 8, 1986 PCT Pub. No. WO86/06567 PCT Pub. Date Nov. 6, 1986.In particular, there are provided in accordance with the invention a method and apparatus for adjusting a digital equalizing filter in a hybrid circuit in a telecommunication system for transmitting digital information in duplex on a single line pair with simultaneous adaptive echo elimination and adaptive elimination of noise caused by intersymbol interference, where a first and a second compensation signal (e(t), i(t)), which are respectively dependent on the stored parameters of a digital balance filter and an equalizing filter, are subtracted from a received signal (a(t)+e(t)+i(t)) to form a difference signal (r(t)) which is compensated for noise respectively caused by echoes and intersymbol interference, the balance filter parameters being corrected with the aid of a correction signal ( epsilon B kappa ) dependent on the difference signal (r(t)). The equalizing filter parameters are adjusted with the aid of a further correction signal ( epsilon U kappa ) formed by the balance filter correction signal ( epsilon B kappa ) and the first compensation signal (ê(t)) such that the further correction signal ( epsilon U kappa ) will substantially agree with the balance filtercorrection signal ( epsilon B kappa ), but obtain the value zero when the first compensation signal (ê(t)) and the balance filter correction signal ( epsilon B kappa ) are both positive simultaneously or negative simultaneously. There is thus prevented the correction sequence of the equalizing filter parameters when the balance filter parameters are changed in a direction such that the absolute value of the estimated echo (ê(t)) increases.
