Abstract: PRIORITY THREADED MESSAGE BURST MECHANISM FOR TDMA COMMUNICATION                         Abstract To make the most efficient use of the TDMA frame for a satellite communications network, the assignment of each local station's TDMA burst duration is based on a statistical assessment of the demand by local voice and data ports.  Occasionally the actual voice and data port demand at a local station exceeds that station's assigned burst duration so that some of the messages which are ready for transmission cannot be transmitted and may be frozen-out.  To avoid or minimize the effects of message freeze-out, the various types of messages are categorized into a hierarchy of priorities for transmission.  Messages are divided into four basic types, control signaling messages which cannot be interrupted without loss of system control, high speed data messages whose flow cannot be interrupted without the destruction of data and the need to retransmit them, low speed data messages whose transmission can be deferred for short periods, and voice messages which can be frozen-out to a limited extent without destroying the meaning of the aggregate voice signals.

Abstract: ABSTRACT A  weighing apparatus, having only one vibrating wire comprises a vertical bar which carries both the scale platform and the magnetic system which deflects the wire, the lower end of which is secured to the vertical bar. A transverse member arranged at right angles to the vertical bar serves to clamp the upper end of the wire, and as a stop for an overload device.  The vertical bar and transverse member have cavities for the accommodation of vibration-damping material.  The apparatus is largely independent of temperature over a wide range and is adequately damped against vibratîons.

Abstract: TITLE OF THE INVENTION:     METHOD AND APPARATUS FOR MANUFACTURING THREE-DIMENSIONAL WORK PIECES            ABSTRACT OF THE DISCLOSURE:     A three-dimensional work piece, such as an interior part for a car, is manufactured by keeping the blank, such as a sheet of plastic on or in the same primary mold for the initial shaping step, for the foaming step, for the curing step and for the final trimming step.  The primary mold shuttles back and forth in a given direction for sequential cooperation with two secondary molds arranged for reciprocation in a di-rection extending perpendicularly to said given direction.          Preferably, two primary mold members are arranged for hori-zontal back and forth shuttling in unison so that each pri-mary mold member may cooperate with two out of three verti-cally reciprocable secondary molds.  The efficiency is substantially doubled when each of the two primary mold mem-bers cooperates with two out of three secondary molds.  Three stations are located next to one another so that the two primary mold members, which are rigidly connected to each other, may shuttle back and forth between two adjacent stations.

Abstract: ABSTRACT: Optical multiplexer and demultiplexer.          Optical multiplexers and demultiplexers utilize interference filters and optical gratings. It is the object of the invention to reduce the losses caused by the use of gratings and filters. This is achieved by the substantially loss-free conversion of unpolarized light into linearly polarized light, so that the efficiency of the filters and gratings is improved. Furthermore, noise is suppressed which is caused by fluctuations in the degree of polarization of unpolarized light because filters and gratings have different characteristics for the different polarization directions.
