Title: Radio communication system and method
IPC: H04B7/26
Filed: 1979-10-26
Abstract: Communication between a first radio transmitter and receiver and a second radio transmitter and receiver is provided by a system repeater. Apparatus for each radio transmitter and receiver in the system establishes communication on a radio frequency channel selected from a plurality of such channels. When such apparatus is in an idle or receive mode, it causes the associated receiver to search the channels for a predetermined group tone or tones assigned to each receiver. When the predetermined group tone or tones are received on a channel, the arrangement enables the associated transmitter and receiver on that channel. When an arrangement is in a call originate or transmit mode, it causes the associated receiver to search for an idle or unused channel. When an idle channel is found, the apparatus enables the associated transmitter and receiver on that channel, and causes the transmitter to transmit a busy tone and the predetermined group tone or tones so as to enable the other transmitters and receivers of the predetermined group on that same channel.

Title: Escalator Safety Device
IPC: B66B29/02
Filed: 1980-02-19
Abstract: A potential safety hazard in escalators is the clearance gap between the edge of the travelling staircase 1 and the escalator side walls 4. In order to minimise the risk of clothing or feet becoming trapped in this gap it is proposed that a strip of brush-like bristles be arranged to project from the escalator side wall across the clearance gap and over the lateral edge of the travelling staircase. The length of the bristles are such that a passenger will contact the bristle ends before reaching the edge of the staircase and reflex action will cause the passenger to move away from the side wall. The bristles, preferably extend at right angles to the side wall and are disposed in a plane parallel to the escalator movement. <IMAGE>

Title: A Method and Apparatus for Measuring the Driving Torque of a Driving System
IPC: G01L3/24
Filed: 1980-03-20
Abstract: In order to measure the driving torque of a driving system, the reaction torque of the system is determined. A stator (1) exerts a moment MA on the suspension (3), which moment is measured together with possible weight components FG at a force measuring device (5) and is converted into an electrical signal by a transducer (7), taking into account the effective lever arm d. Using a predetermined correction magnitude UG,the concomitantly determined weight component is corrected. By converting the stator acceleration in a transducer (9) and considering the stator moment of inertia at an amplifier (13), moment of momentum changes per unit of time of the stator are taken into account to determine the output magnitude U"M corresponding to the net torque of the system. In an alternative embodiment, a net-torque signal is gated out at instants when the measured acceleration of the stator is zero. <IMAGE>
