Title: Multiple access communication system capable of deciding a connection route among a central station, repeater stations, and terminal stations
Inventor: ARAI KOJU
IPC: H04Q3/00
Filed: 1992-02-26
Granted: 1998-08-11
Abstract: In a multiple access communication system comprising a central station, at least one repeater station, and at least one terminal station, each of the central, the repeater, and the terminal stations has each station number.  The central station transmits a central downward signal comprising a central number signal representative of the station number of the central station to the repeater station.  The repeater station separates the central number signal from the central downward signal.          The repeater station transmits a repeater downward signal comprising a repeater number signal representative of the station number of the repeater station to the terminal station.  The terminal station separates the repeater number signal from the repeater downward signal as a separated repeater number signal.  The terminal station transmits an upward signal to the repeater station.  The upward signal comprises the separated repeater number signal and a terminal number signal representative of the station number of the terminal station.  The repeater station receives the upward signal and transmits to the central station a central upward signal which comprises the central and the repeater number signals, and the separated and the terminal number signals.  A central processor (106) carries out a process operation by the use of a combination of the central and the repeater number signals and a combination of the separated and the terminal number signals.

Title: Cutting device for a wire-removing machine
Inventor: GRONAU KURT
IPC: B65B69/00
Filed: 1990-12-13
Granted: 1996-11-12
Abstract: A cutting device for a wire-removing machine for severing the tying wires of bales, especially of pulp bales, consists essentially of two elongate knives (5, 6) which can be pushed to and fro relative to one another and which are equipped on each of their cutting sides with a tooth row consisting of teeth (16, 17) arranged at regular intervals in succession and having an undercut on their flanks located at the front in the cutting direction. So that the cutting moment is defined exactly and at the same time to ensure that a gripping device retains the tying wires reliably even before they are severed by the cutting device, the front flanks (18, 19) of the teeth (16, 17) each have at their lower ends, in the region of the tooth root, a receiving pocket (21, 22) for at least one tying wire,  the rear ends of the receiving pockets (21, 22) being designed as a cutting edge (24). The front flanks (18, 19) of the teeth (16, 17)  are designed as obtuse   sliding faces  in their portion between the tooth tip (20) and the respective receiving pocket (21 or 22). (Figure 1)

Abstract: A rotating elevator motor provided with a traction sheave  is  placed  in the  counterweight  of  an  elevator suspended with ropes, so that the motor structure shares part of the counterweight structure, thereby economizing on space.    The  sector-shaped  stator of  the motor has  a diameter (2*Rs)  larger than that (2*Rv) of the traction sheave and the elevator ropes are passed through the open part or parts of the stator.  This structure allows the use of traction sheaves of different diameters with rotors of the same diameter.  Still, the length of the motor remains small and the motor/counterweight of the invention can be accommodated  in  the  space  normally  reserved  for  a counterweight in an elevator shaft.   The motor shaft is placed in the counterweight substantially midway between the guide rails and the same number of ropes are placed on both sides of the rotor.
