Patent SE-7711282-L (SE)
Inventor: KNOLLMAN D J H
IPC: H04M3/42
Filed: 1977-10-07
Abstract: This specification discloses a telephone conferencing arrangement employed with a plurality of conference interface ports in a time division multiplex (TDM), private branch exchange (PBX). Each port receives from the PBX the TDM conference signal of a respectively associated conferee and transmits an analog version of the conference signal to the conferencing system. Conferencing is achieved by combining the analog conference signals into a plurality of composite signals which are subsequently recombined via resistance-value related conductive paths with the uncombined analog conference signals in selectable transmission phases and amplitudes so as to provide at the receiving terminal of each conference interface port a composite signal comprised of the selectably phased conference signals transmitted by the other conference interface ports. Thus, when the PBX retransmits to the conferencing system a portion of each of the received composite signals, the retransmissions tend to cancel each other, thereby preventing regenerative instability in the conferencing system.

Abstract: Between a brake motor (2) and an output member (18) which outputs the application force, the application device has a wedge mechanism (19) with a rolling element which rolls on a wedge surface (19). As part of the wedge mechanism (19) there is a lever (15) which can be pivoted in the common plane of the direction of force of the brake motor (2) and the direction of the application force and is supported, at one end, at a fixed mounting point (14) and centrally on the output member (18). At the other end, the lever (15) is coupled via the wedge surface (19) and the rolling element to the brake motor (2). The output member (18) is kept free of transverse force components and, as a result, a high efficiency of the application device can be achieved. <IMAGE>

Abstract: The invention concerns a process and apparatus for the opening- up of raw green vegetable matter. In the process fresh green vegetable matter is mechanically opened up by a combined and sequential breaking, crushing, disintegrating, rubbing and cutting, hitting and gentle pressing operation, having been passed through a mechanical opening-up apparatus once. The fibrous fraction of the thus obtained material is adjusted to a length of not less than 3 mm then the pulped vegetable matter is pressed at ambient temperature. A surface-active material may be added before starting the process. The apparatus comprises grinding chamber provided with a working surface, a rotor in the grinding chamber carrying oscillatably suspended breaking hammers, and a housing bounding the grinding chamber and provided with inlet and outlet ducts. The working surface is a liner having mutually parallel guiding channels diverging at an acute angle from either side of a vertical bisection line towards the right and left edge of the liner. The gap between the grinding surface of the liner and the envelope of the tips of the breaking hammers decreases from the inlet towards the outlet ducts. <IMAGE>

Abstract: A measuring controlling device for a circular grinding machine including grinding means and workpiece retaining means for rotatably holding a workpiece to be ground comprises two measuring key devices and a measuring head for supporting the measuring key devices. The measuring key devices are located on a diametrical line extending through the central axis of the workpiece to be ground and are brought into contact with the outer surface of the workpiece therebetween. The measuring head is moved relative to the axial direction of the workpiece to be ground so that the measuring key devices can contact the entire outer surface of the workpiece. Consequently, the workpiece can be ground by means of the grinding means into a predetermined profile with reference to the actual profile measured by the measuring key devices.

Abstract: In order to night-extinguish selected lamps (P<uN>u) in a row of street lamps (P) a short DC signal is applied to the AC power supply wires (F<u1>u, F<u2>u), whereby respective detector receivers (M) in the single selected lamp units (P<uN>u), e.g. every second lamp in the row, are caused to actuate a switch (30) for the respective lamps. A DC signal will be effective for this purpose, while an AC signal of high frequency would be strongly attenuated because of the condensers as commonly used in modern lamp units. The use of DC signals may show the problem that during the switching on phase of the lamps the ohmic resistance is very low, whereby the DC signal would be more or less suppressed by a relighting of the night-extinguished lamps, if the DC current was not otherwise unacceptably high; according to the invention, however, the relighting is caused to take place only after termination of the DC signal. A plurality of separately power supplied rows of lamps may be operated for partial night-extinguishing by the DC signal on a first row being utilized for actuation of a DC signal generator in a following row, and so forth.

Abstract: In order to facilitate the removal of ash and slag from a furnace, consisting of a cylindrical combustion room (10), which is extinguished at the base by a primary air flow grid (11), on which solid fuel material is supplied from below, one arranges that the grid meeting the injected primary air supply can be divided between a central section (14) and a surrounding concentric section (15).A conical mound of fuel material (13) is normally maintained on the grid, which reaches right out to the furnace wall.  The grid plates (15 a) in the outer grid section (15) are movable and, during ash disposal, the air vent to the central grid section (14) is closed and air supply increased to the outer section (15).  When the resting fuel stuff is burned up, the grid plates (15 a) are moved so that ash and slag fall down in to a water-filled ash box (28). The remnants from this are fed out by means of a screw (33).Once the ash removal is completed, the plates (15 a) are moved back and air supply is recommenced for normal operation.<IMAGE>

Abstract: A base plate (3) is used to accommodate a foil (1) with a gel plate (2), and is of plastic, being vaulted in its transversal direction. The formation causes the wire (4) to be tensionsed to press the foil against the baseplate with the same force along its whole length. The wire is maintained tensioned crossways over the base plate between two hand grips (5,6) displaceably fastened in tracks (7,8) in the base plate on opposite sides of the foil with the gel plate. One end of the wire is fixed to one hand grip (5), whilst it is tensionsed in the other hand grip (6) via a draw spring (9), one end of the spring being fixed to the wire, and the other to a pin (10) on the hand grip. After the foil and gel plate have been clamped to the base plate using a clamp (11), the wire between the hand grips is tensioned with its one end position nearest the clamp. This causes the wire to cut through the gel plate unitl it comes in contact with the foil. By pushing the hand grips in the appropriate direction, the wire is pushed between the foil and the gel plate. (Provisional basic advised week 8830)
