Granted: 2009-01-20
Abstract: An integrated system for the control of pedestrian traffic flow in heavily attended events.The control of traffic flow is achieved using audio massages that are broadcast or multicast to pedestrians via aradio channel. The integrated system is comprised of two subsystems: 1- Traffic flow monitoring, and 2- Audio wireless transmission. The former (1) is designed to provide traffic measurement capabilities (tools) such that cases of congestions or extensive traffic flow are automatically detected. The latter (2) is used as a tool to transmit traffic flow control messages to pedestrains to provide traffic redirections messages in cases of congestions. In cases of emergency, it is also used to transmit warnings and audio information pertaining to the safety of pedestrians. The system also provides a medium for the communication of relevant educational and/or commercial material in audio format.

Title: Emergency retraction means for the manipulator arm of anuclear reactor vessel inspection apparatus
Inventor: MORRIS D
IPC: G21C9/00
Filed: 1978-03-23
Granted: 1981-10-23
Abstract: The pulley(149) is mounted on a bracket on the manipulating arm.  The cable(142) is fixed at both ends to the carrier (82) of the manifulating arm and passes over the pulley.  It can be detached at one end and drawn upwards, forcing the pulley to move so that it retracts the telescopic arm(126) to which it is attached to a position in the holder.  This action retracts an inner telescopic arm into the holder, together with the transducer matrix which the inner arm carries.  Problems associated with retracting the arm in the case of an incident occuring when it is fully extended, e.g. an electricity supply failure with the transducer matrix in a nozzle on the reactor, are avoided.

Abstract: The digital phase difference detection circuit has a phase shifting circuit for shifting by plus or minus 90 degree phase of an input signal which has been sampled over a predetermined sampling period. A dividing circuit divides an output signal of the phase shifting circuit by the input signal.  An operation circuit performs an inverse trigonometric function operation on an output signal of the dividing circuit.  A subtracting circuit obtains the difference between an output signal of the operation circuit and a phase of a reference signal.  The resulting output signal of the subtracting circuit indicates the phase difference between the reference signal and the input signal.

Title: Process for producing films especially those based on polyvinyl butyral with a slight surface tackiness
Inventor: PABST HORST
IPC: B29C48/31
Filed: 1985-12-23
Granted: 1990-03-26
Abstract: Films based on polyvinyl butyral, or on polymers with similar properties, are produced with little tackiness by extruding from a wide slit die and making the plasticated melt into a film with a feed passage, manifold and outlet in the die.  Beyond the menifold, the slit die is brought to a temp. which is lower than elsewhere so that a temp. difference is produced between the surface and the centre of the stream of melt which is forming the film; the resultant shear effect in the solidifying melt stream produces a roughened surface on the film and hence a low surface tackiness.  The film is produced without any surface embossed effects or undercuts in its surface.
