Patent CA-2030201-A1 (CA)
Title: Bobtail relay valve
Inventor: JOHNSTON JEFFERY S
IPC: B60T13/26
Filed: 1990-11-16
Abstract: Abstract of the Invention A control valve, braking system, and method for changing the ratio of a delivery pressure output relative to a first control pressure input according to whether a second control pressure input is present or absent.  One application of the valve is in a pneumatic braking system for a tractor-trailer rig.  In this application the first control pressure is a function of the braking force applied to the brake pedal by the truck driver.  The delivery pressure determines the braking force delivered to the tractor brakes.  The second control pressure is the trailer braking pressure transmitted to the control valve, and is present only when a trailer is connected to the tractor.  When trailer pressure is present, the control valve keeps the first control pressure and delivery pressure about equal.  When trailer pressure is absent, the first control pressure to delivery pressure ratio is raised substantially, thus reducing tractor braking force when the tractor is driven with no trailer attached.

Title: Arrangement for detecting an object by means of sound conducted through a solid body and method of using such arrangement
Inventor: MULLER BRUNO
IPC: B61L29/22
Filed: 1991-01-03
Abstract: To identify an object (2) which emits structure-borne noise onto a base, for example a railway vehicle approaching a track construction site, the vibrations (S) generated by the structure-borne noise are detected by a structure-borne noise recorder (2) attached to a rail (1) and are processed by an evaluation circuit (C). A  warning signal (Sw) is emitted when the intensity of the output signal (Sa) from the recorder constantly increases, for example when the intensity exceeds given threshold values in a suitable frequency range in predetermined times; in other words, constantly swelling noise propagated in the rails (1) is evaluated as a reliable criterion for emitting a warning signal that indicates an approaching train.
