Title: Friction plate return mechanism
Inventor: RAYMOND BENOIT
IPC: F16D55/34
Filed: 1999-11-15
Abstract: A friction plate return mechanism is provided for disengaging a brake plate from frictional contact with a rotor disk in a brake assembly for vehicles. The mechanism includes a pin slidably received in a casing that is mounted to the vehicle. The pin is biased by a spring to a rear position and is fractionally connected using a retaining washer to the brake plate to move the brake plate in a rearward direction away from the rotor disk when a braking force is removed from the plate.      Another retaining washer is received within the casing and axially movable in a predetermined distance. This retaining washer is also fractionally connected to the pin for permitting the pin freely moving in the forward direction with the brake plate during a braking action, but stopping the pin in a rearward movement together with the brake plate except moving together with the retaining washer over the predetermined distance. The advantages of the mechanism include a constant returning force and a constant travel distance of the brake plate regardless of the wearing of the contact surfaces between the brake plate and the rotor disk during the lifetime of the brake assembly.

Title: Radio wave environment analyzer
Inventor: KUWAHARA YOSHIHIKO
IPC: H04W24/00
Filed: 1999-12-24
Abstract: A radio wave environment analyzer of the present invention includes a transmitter for radiating a signal subjected to BPSK (BiPhase Shift Keying) modulation using a PN (Pseudo Noise) code sequence via a transmission antenna. A receiver includes an array antenna for receiving the signal sent from the transmitter. The outputs of antenna elements constituting the array antenna are sequentially selected. Each of these outputs is multiplied by a signal fed from a PN code generator and identical in code sequence with, hut slightly different from, the signal received from the transmitter and inversely spread thereby. The inversely spread signal is transformed to a baseband signal and then subjected to orthogonal detection. A signal processing device displays a delay profile representative of a relation between the power of detected signals and the delay time. In addition, directions of arrival are calculated on the basis of a designated period of time for direction of arrival analysis with the result that a PDA (Power, Delay and Angle) gram is displayed.

Patent CA-2299986-A1 (CA)
Inventor: HESCH ROLF
IPC: D01G11/00
Filed: 2000-03-06
Abstract: A device to treat or process and especially to disintegrate materials and compounds characterized by a rotor, to which mentioned materials are fed axially. The rotor centrifugally accelerates the input material to a tool ring rotating around the rotor preferably in opposite direction, in which the tools are arranged radially. The tools of the tool ring intercept the highly accelerated material in flight and induce an extreme shear and bending strain effecting that the material disintegrates at its natural weak point. The tools are arranged at the circumference at such distances that a largely open circumference is established. That effects that the disintegrated components of the material can be discharged from the device after the impact without any hindrance even if the material is wet or sticky. The degree of impact of the tools on the material can be adjusted by the regulating parameters. That offers a large field of applications to disintegrate and separate raw materials and waste materials consisting of physically sufficiently different components into their individual components.
