Abstract: SUSPENSION CEILING GRID SYSTEM WITH NARROW-FACED GRID     ABSTRACT OF THE DISCLOSURE           A narrow-faced suspension ceiling grid system is disclosed which includes grid tees providing central webs and relatively narrow. oppositely extending flanges in combination with panel centering means.  The narrow flanges provide improved aesthetics and reduce the mater-ial required to form the grid tees when compared to con-ventional wide-faced grid tees.  The panel supporting flanges are sufficiently narrow that if the grid were used with conventional panels having a conventional amount of clearance, they would not reliably support the panels in the grid.  However, when the centering means are provided to center the panels within the panel receiving openings, reliable support is provided for the panels.

Abstract: ABSTRACT    C4 olefins comprising cis - and trans-butane-2 and butene-1 may be oxidized to their corresponding mono- and diacetates in the presence of acetic acid and an olefin-activated palladium catalyst under mild condi-tions.  With this catalyst, and depending in part upon the solvent employed, as well as other operating conditions, the formation of linear allylic 1-acetates over the corresponding branched compounds can be favored in order to increase the yield of the corresponding linear 1,4-diacetates.  The latter, in turn, may then be converted, for example, to butanediol by known hydrogenation methods.     In a similar manner, isobutylene may be converted to a dialcohol.

Abstract: ABSTRACT OF THE DISCLOSURE      A parallel vector processor is disclosed.  The vector processor comprises a plurality of vector registers, each vector register being subdivided in a plurality of smaller registers.  A vector is stored in each vector register, the vector comprising a plurality of elements.  The elements of the vector are assigned for storage in the smaller registers of the vector register.  In the parallel vector processor of the present invention, assume that each vector register is subdivided into M smaller registers.  The first successive M elements of an N element vector are assigned for storage in the M smaller registers of the vector register.  An element processor is connected to each smaller register.  Therefore, the first successive M elements of the N element vector are processed by the element processors 1 through M. The second successive M elements of the N element vector are assigned for storage in the same M smaller registers.  The third successive M elements of the N element vector are assigned for storage in the M smaller registers.  The second and third successive M elements of the N element vector are each processed by the element processors 1 through M.  As a result, if the elements of a vector must be processed sequentially, when a second element, stored in a smaller register, is ready for processing bar an element processor, the processing of the second element need not await the completion of the processing of a first element stored in the same vector register.

Abstract: ABSTRACT:          "Multi-pulse excitation linear-predictive speech coder"     A multi-pulse excitation linear-predictive speech coder operates in accordance with an analysis-by-synthesis method for determining the excitation. The coder (10) comprises an LPC-analyzer (11), a multi-pulse excitation generator (13), means (12, 14) for forming an error signal representative of the difference between an original speech signal (s(n)) and a synthetic speech signal (s(n)), a filter (15) for perceptually weighting the error signal and means (16) responsive to the weighted error signal (e(n)) for generating pulse parameters controlling the excitation generator (13) so as to minimize a predetermined measure of the weighted error signal. The LPC-parameters and the pulse parameters of the excitation signal (x(n)) are encoded for efficient storage or trans-mission. The bit capacity required for pulse position encoding of the excitation signal (x(n)) is considerably reduced by arranging the excitation generator (16) for an excitation signal (x(n)) which in each excitation interval (L) consists of a pulse pattern having a grid of a predetermined number (q) of equidistant pulses and by arranging the control means (16) for generating pulse parameters characterizing the grid position (k) relative to the beginning of the excitation interval (L) and the variable amplitudes (bk(j), 1 ? j ? q) of the pulses of the grid (Figs. 1 and 2).

Abstract: ABSTRACT OF THE DISCLOSURE           The invention is a further development of the gear-head unit for a manipulator described in German Open Patent Application 34 28 748. In order to increase the radius of action and range of applicability of the gear-head unit a structural arrangement with three concentric drive axes and four allowed rotational motions of front, intermediate and rear segments of the manipulator is set forth. These front, intermediate and rear segments are pivotally mounted together about first and second inclined pivot axes which are inclined to each other and to the main drive shaft axis.  Along these inclined pivot axes two hollow drive shafts connected with each other extend which are supported by reduction gears in the front and/or intermediate segments. Because of that simultaneous opposing rotational motions of the intermediate and rear segments can be obtained from a single drive motor.  In the rear segment an output drive shaft attached to a front plate for a tool holder is rotatably mounted which is driven by coupled intermediate drive shafts guided through the hollow drive shafts.
