Patent PT-86798-B (PT)
Inventor: KLOSE REINHARD
IPC: H04M3/56
Filed: 1988-02-19
Abstract: A method of making conference call connections in computer-controlled telephone exchanges includes combining voice signals of conference participants on a digital basis, forming a signal of a total of speaking levels of a given number of the most active participants, distributing the signal in an undamped manner, and suppressing voice signals of the inactive participants. A bit stream of the conference participants reaching a conference assembly through an incoming line is distributed to m adding processors having n channels each, and the PCM words are linearized with a code table and stored in level memories for each particular participant. A total of the linear values is formed, is added to individual participant evaluation totals and is stored in evaluation memories for each particular participant. The participant evaluation totals are transmitted to an evaluation processor which determines active channels by using a delayed mean value of the participant levels and transmits it to the adding processors. A conference total signal is created by adding linear values of all channels. Transmission signals for all channels are formed in the adding processors by compressing the conference total signal, the individual linear value of the active participants being substracted before compression. The signals thus created are stored in transmitting memories and transmitted through an outgoing line.

Title: Lacemaking pad
Inventor: HEDENSTOM HENRIK N
IPC: D04C7/00
Filed: 1981-05-18
Abstract: In connection with all manual lacemaking based on the so- called "Vadstena method" one should use a lacemaking pillow, lacemaking pins, suitable thread, needles and lace pattern. Many lace patterns are designed so that the threads are laced across the lace from right to left and reversed or in a sunflower design are laced from the outside of the lace to its middle and then back towards its outside edge. These threads are called "run pairs". On this lace pad, the felt roll is permanently fixed in the horizontal plane but can be turned. The basic principle of my invention, a rotatable centre part, is that the person lacing can freely turn the centre part with the felt roll to any position based on the design of the lace pattern. <IMAGE>

Abstract: A roof tile patterned plate 15 ia manufactured by first pre-profiling a plastic covered plate by roll forming, and then providing this plate with cross-running steps 22,23 in a machine having two pairs of tools 11, 12 resp. 13, 14 from which one is vertically movable, i.e. perpendicularly to the plane of the plate, to give a shaping motion. The tool pairs define slots for the pre-formed plate so that the plate preferably gets no holding force what so ever but may be freely drawn in into the tool pairs during the forming motion of the movable tool pair 13, 14. A stop 16 prevents the plate from being drawn in into the movable tool pair 13, 14 during the end phase of the forming motion so as to thereby define the distance between the steps. The forming is lenient to the plate and gives a neat result with an accurate distance between the steps. <IMAGE>
