Abstract: A clamping device for rotatably driving an information carrying record such as a rigid or flexible video record and comprising a drive spindle, a record support disposed thereon, a substantially conical centring member having a diameter which varies from a diameter smaller than to greater than that of the record hole, which also during operation co-operates with the edge of the central hole in the record, and furthermore resilient pressure means for pressing the centring surface and the edge of the central hole in the record against each other. The centring member is rigidly connected to the record support, while the part of the centring surface which co-operates with the record hole is disposed at some axial distance from other parts of the record support and a resilient record loading device is provided which during operation bears on the record and is movable opposite to centring member for pressing the edge of the record against the centring surface, so that during starting the record can tilt into a plane which is perfectly perpendicular to the axis of rotation of the drive spindle under the influence of the centrifugal forces acting on it.

Abstract: 1-Oxo-2,2-disubstituted-5-indanyloxy(or thio)alkanoic acids and their salt, ester, anhydride, amide and 5-tetrazolyl derivatives are disclosed. The products display a dual pharmaceutical utility in that they exhibit diuretic, saluretic and uricosuric activity. The acid products are prepared by treating a 2,2-disubstituted-5-hydroxy(or mercapto)-1-indanone with an haloalkanoic acid or ester thereof and, if the ester is employed, hydrolyzing the ester.

Abstract: An improved check valve has an operating chamber with a disc disposed therein which is capable of axial movement from a closed position against a valve seat to an opened position to prevent feedwater from flowing from the normal outlet to the normal inlet of the valve. A cylindrical member extends upwardly from the disc through a fixedly mounted baffle plate which generally separates an upper portion of the operating chamber from the lower portion. A piston is mounted on an extended end of the cylindrical member to generally define a dashpot chamber between the piston and the baffle plate. The dashpot chamber entraps a greater volume of feedwater when the valve is open than when closed to limit valve closure rate by limiting the rate at which feedwater leaves the dashpot chamber during closure.

Abstract: The parent patent described the leaching of a sulphide ore or concentrate, contg. Pb and other metals, with an aq. soln. contg. the chloride(s) of Cu, Bi and/or Ag, using below the stoichiometric amt. of chloride needed for complete soln. of the Pb. - In this addn. the Pb in soln. is recovered as PbCl2 crystals, which are then melted and reduced by H2. Redn. is pref. at 750-850 degrees C., esp. using H2 diluted by an inert gas and injected into the molten PbCl2. The hourly flow of H2 is pref. at least twice the stoichiometric amt. necessary for total redn. of the PbCl2; and the H2 in the gases leaving the redn. process is pref. sepd. from the HCl obtd. and recycled to the redn. process, whereas the HCl is recycled for dissolving the lead. - Metallic lead with high purity can be obtd.; the Cl ions are directly recovered as HCl which is recycled; and the reducing agent is inexpensive. The process also eliminates extra processing stages which were necessary with the earlier patents.

Abstract: Light responsive elements of a color imaging array are arranged in basic groupings of four aligned elements, which groupings included two luminance-responsive elements that alternate with individual elements for two other basic colors. These groupings are repeated along a line and are shifted by one element in each adjacent line. As a result of intermixing color-responsive elements in this way, high-spatial-frequency luminance sampling is achieved for all directions on the array and closely repeated patterns of elements are achieved for all three basic colors in both fields of the array (here assuming a two-field interlaced readout array). Because closely repeated sampling occurs for all colors in both fields of such an array, the field-to-field color flicker, that can occur when intermixed color sampling is attempted using an interlaced-readout imaging array, is avoided.

Abstract: A soil cultivating machine has a front row of subsoil penetrating tools and a second soil working member or row of members that work the top soil. The tools can be strip-shaped tines, at least some of which have plate-shaped elements pivoted to their lower ends. The elements or tines are connected to an eccentric mechanism that periodically raises and lowers the elements as the machine is operated. The second soil working member can be a row of tined rotors or an elongated further working member that extends transverse to the direction of travel and works the top soil from a direction that is different from the direction of movement of the strip-shaped tines. Intermixing the worked top soil and the subsoil is prevented.

Abstract: The apparatus is provided, for a first user, with a freely accessible first input device (31) for an identification word and with a second input device (33) for a particular keyword, which are both inaccessible to a further user. A first encoding device (37) for the identification word and the secret keyword supplies a code word which is compared with an already stored code word by means of a comparator device. If both code words are identical, the transaction can be initiated. For this purpose, the apparatus contains a third input device (39), inaccessible to the first user, for a control word of the further user, the identification word and the secret key word, together with a control word, being encodable to the stored code word in a first encoding device (37). So that there is the possibility of keeping a secret keyword of the first user secret even from the further user, the further user also at the same time uses a similar control word in order to ensure that transactions can be conducted only by him and not by other users of the system. <IMAGE>

Abstract: The present invention relates to a method for controlling the combustion course in an Otto engine, and an arrangement for working the method. According to the invention, both an ordinary engine fuel, and an agent B affecting the combustion in the engine with the ability to reduce the risk of abnormal combustion, so-called knocking, in the engine, are introduceable into an Otto engine 1. In order to obtain maximum performance from a fuel-air mixture introduced into the engine 1 at simultaneous minimum consumption of fuel and supplementary agents, the introduction of the agent affecting the combustion is controlled in dependence of signals from a so-called knocking detector 22, which in a way known per se senses knockings occurring in the engine. <IMAGE>

Abstract: A digital signal is encoded for error correction, and the encoded digital signal is transmitted in M transmitting paths. The signal to be encoded occurs as N sequences of data words. A plurality n of sequences of error correcting words are generated from respective words of the N sequences delayed by respective different delay times of (D-di) words, where di is a whole number associated with an ith one of the n error correcting word sequences. The resulting N data word sequences and n error correcting word sequences are provided with respective different total delay times, so that the total delays of the N sequences differ by an integral number D of words from one another. Blocks of the delayed N data sequences and n error correcting word sequences are formed and the blocks are cyclically distributed among the M transmitting paths. The values of M, N, n, D, and di are selected so that the least common multiple of any two values of (d-di) is greater than (N+n-1)D; and for any value of (D-di), (d-di) and M are relatively prime. Favorably, M is selected as 2 k, and (D-di) is odd.

Abstract: The use of polyisocyanates as binders in the preparation of particle boards is subject to the drawback that the boards exhibit a tendency to adhere to the face of the platens used in their formation. This problem is minimized by incorporating minor amounts of certain phosphinic and or phosphonic acids or derivatives thereof or phosphites into the polyisocyanate to be used as binder. The polyisocyanates and the phosphorus compounds are applied to the particles separately, or after preblending one with the other. Whether the components are applied separately or in combination one with the other, they can each be applied either neat or in the form of an emulsion or emulsions.
