Abstract: OPTICAL FIBER CABLE AND METHODS OF MAKING            Abstract An optical fiber cable (20) includes a core (21) comprising plurality of units (22-22). Each unit is formed by a plurality of optical fibers (24-24) which are assembled together without intended stranding. The plurality of units are enclosed in a common tube (34) which provides a predetermined packing density and which is substantially parallel to the longitudinal axis of the cable.  In one embodiment, a waterblocking material (36) is disposed within the tube to fill the interstices between the optical fibers and between the units. The waterblocking material is such that its critical yield stress does not exceed about 70 Pa at 20°C and such that it has a shear modulus of less thann about 13 KPa at 20°C. The common tube is enclosed with non-metallic or metallic strength members and a plastic inner jacket and by another layer of strength members and by a plastic outer jacket. This arrangement is such that the cable may be manufactured and installed with the optical fibers capable of moving within the cable structure to prevent undue stresses being imparted thereto which would cause unwanted microbending losses.

Abstract: ABSTRACT            In a vocoder, a digital speech signal to be coded is split into subbands and each subband is coded independently. The two lowest frequency subbands undergo an adaptive linear prediction operation yielding a residual which is normalized with respect to a quantized r.m.s. value;  the residual samples are quantized and coded with variable bit number.  In a third high frequency subband the samples are normalized with respect to a quantized gain term and directly quantized and coded using a variable bit number.  During splitting of the subband signals into sample blocks, for the first two subbands the coefficient vectors of subband linear prediction filters relevant to each block are also determined by vector quantization and linear prediction inverse filtering operations;  quan-tized r.m.s. values are also determined to calculate the number of bits required for coding of the subband sig-nals.  The coded signal consists of subband signal quan-tization level indices, of r.m.s. value quantization level indices, and of linear prediction filter coeffici-ent vector indices.

Abstract: Abstract of the Disclosure A clamp assembly for clamping unslotted overlapping ends of metal tubes in an exhaust system. The clamp assembly includes a metal ring having a generally circular cross section and the ends of the ring are in overlapping contacting relation.  One leg of a generally U-shaped bracket is secured to each overlapping end, while the other leg of the bracket engages the outer surface of the other end of the ring to urge the overlapping ends of the ring into contacting relation.  A bolt extends through the aligned openings in the brackets, and the axis of the bolt is in a plane passing through the line of contact between the overlapping ends.  The head of the bolt bears against the side edge of one bracket while a nut threaded on the opposite end of the bolt bears against the side edge of the other bracket.  By threading down the bolt, the ring is contracted in diameter to provide a low cost, strong, 360° closure for clamping the tubes.

Abstract: ABSTRACT OF THE DISCLOSURE    An electromagnetic shield-type doorway for a building is provided with two doors having a curved passageway between them.  By lengthening the passageway to such an extent that the two doors cannot be opened simultaneously, electric waves can be blocked at either of the doors.  The electromagnetic shielding effect can be enhanced by installing a revolving door in the passageway and attaching electrically conductive brushes to at least the lower edge and one side edge of the revolving door to fill the gaps at these edges.  In a system for electromagnetically shielding a building, a doorway passageway of the building is partitioned by three or more doorways each having an electromagnetic shielding function.  When persons leaving and exiting a building simultaneously approach entrance and exit doors at the ends of the doorway passageway so that these doors open at the same time, the central doorway remains closed to maintain the integrity of the electromagnetic shield.  If a large number persons are entering and exiting, the doors are opened and closed in an interlocked manner so that one of the three doorways will always be closed, thereby maintaining the integrity of the shield in reliable fashion without hampering entry and exit.
