  • Patent number: 4572350
    Abstract: A first transporting unit advances a series of stacks of paper sheets along a straight first path. A transfer conveyor can be lifted into the first path to divert selected stacks into the range of a second transporting unit which defines a second path making an oblique angle with the first path. The transfer conveyor is assisted by a pusher which is adjacent to the first path opposite the stack-receiving end of the second transporting unit and is movable at right angles to the first path to move the diverted stack sideways. Such stack strikes a yieldable bumper which expels it from the second path into the range of a third transporting unit serving to advance stacks in parallelism with or at right angles to the direction of movement of stacks along the first path. The orientation of selected stacks remains unchanged during diversion from the first into the second path as well as during diversion from the second into the third path.

  • Patent number: 4571839
    Abstract: A bore gauge incorporates one or more electromagnetic transducers housed in a shroud which in use is inserted into the bore to be gauged. Each transducer comprises a coil and a core movable within the coil. In one embodiment the coil and the core of a single transducer are mounted on opposite limbs of a flexible fork-like structure, the two limbs carrying gauging contacts for engagement with the walls of the bore. In other embodiments, incorporating a plurality of transducers, coils are rigidly mounted within the shroud and cores are mounted on flexible limbs set in slots in the surface of the shroud.

  • Patent number: 4570534
    Abstract: A system and method of reducing the alcohol content of wine by exposing an original wine product to an elevated temperature in a centrifugal film evaporator and removing therefrom a liquid phase reduced alcohol wine and a vapor phase of relatively high proof. The original wine product is added to the reduced alcohol wine in predetermined ratio to increase the alcohol content and introduced desired properties and characteristics. The vapor phase is passed through a distillation unit and step to increase the alcohol content of the vapor phase.

  • Patent number: 4571306
    Abstract: Residual lipophilic reactants and by-products of surfactant manufacture (e.g. fatty alcohols, ethers, esters, etc.) may be adsorbed from surfactant compositions with a solid hydrophobic sorbent having pore sizes sufficiently small enough to effectively preclude molecular adsorption of the surfactant molecules therein. Surfactant compositions containing long-chain alkyl glucoside mixtures, as the major active surfactant component, may be refined to a form substantially free from lipophilic impurities by dispersing the surfactant composition into a suitable liquid carrier system and adsorbing the contaminants from the composition with the sorbent.

  • Patent number: 4571732
    Abstract: An adaptive equalizer for high-speed binary signals, operating in baseband, comprises a transversal filter receiving digitized samples of incoming symbols and feeding them to a decision stage. The samples also go to a coefficient computer, in parallel with that filter, which includes a filter simulator, an error calculator and a processor delivering corrective coefficients to the filter. A register in the filter simulator accumulates a predetermined multiplicity of received samples (e.g. 150) which are jointly convoluted with an initial set of coefficients to yield a mean square error supplied by the error calculator to the processor; the latter, for each coefficient of the initial set, selects two collateral values which are successively substituted for that coefficient to yield two further mean square errors.

  • Patent number: 4571238
    Abstract: A rotor for a centrifuge is provided with a peripheral groove having confronting slots communicating therewith. A retaining member is disposed so as to overlie each of the slots by a predetermined radial distance. The radial dimension of each slot is greater than the sum of the radial distance by which the retaining member overlies the slot and the radial thickness dimension of a tube carrier receivable within the slots. Thus, the tube carrier is movable within the slots from a first, radially inner, position to a second radially outer, position in response to centrifugal force such that when in the second position movement of the tube carrier in a direction parallel to the axis of rotation is prohibited.

  • Patent number: 4569260
    Abstract: A pliers-type hand tool has a pair of pivotally connected jaw-forming members defining jaw portions on one side of the pivot connection and elongate slotted lever portions on the other side of the pivot connection. A slide pin is received in the lever portion slots and is connected by pivot links to operating handles which are attached to the pivot connection in common with the jaw-forming members. The arrangement produces a mechanical advantage between the handles and the jaw-forming members allowing a greater jaw-closing force to be developed, related to the manual effort applied to the handles, than with conventional pliers-type tools of comparable size.

  • Patent number: 4570099
    Abstract: A thermionic cathode (FIG. 1) comprises an emitter (3) comprising a matrix (4) of tungsten impregnated with an alkaline earth activator. The matrix is coated with a coating (5) of about 20-30% osmium fully alloyed with tungsten formed by cosputtering osmium and tungsten onto the matrix. A diffusion barrier (6) of osmium may be interposed between the matrix 4 and coating (5) (FIG. 2) and, optionally, osmium may be diffused into the matrix (4). Alternatively the whole matrix may comprise a mixture of about 20-30% osmium fully alloyed with tungsten (FIG. 3). Alternative to osmium and tungsten may be used, and various modifications may be made, and other methods of making the emitter may be used. In particular the proportion of osmium may be about 40%.

  • Patent number: 4569937
    Abstract: Pharmaceutical compositions of narcotic analgesics and ibuprofen have been found to exhibit unexpectedly enhanced analgesic activity by applying an analysis model which considers data characterizing the analgesic effect of both the pure components as well as the fixed dose ratio combinations. This synergism enables the use of lower doses of either or both drugs with a concomitant reduction in risk of possible side effects.
