Abstract: A pressure sensor that responds to a predetermined rate of change of pressure in the fluid medium comprises a housing that encloses a pressure chamber which has a divider wall that consists of a printed circuit board and a flexible diaphragm which is permeable. The divider wall serves to separate the pressure chamber from the pressure sensitive system in which the sensor is used. The sensor may be used in a pneumatic tire and in such use the flexible diaphragm will be deflected to activate a transmitter when the pressure in the tire changes at a hazardous rate. The sensor will not activate the transmitter when the rate of change of pressure is less than a hazardous rate of change.

Abstract: In a human-in-the-loop robotic control loop, the constrained forces and moments at the gripper (also called hand or end effector) of the manipulator are measured by a force-mement sensor. The resulting force and moment signals are scaled and fed as input voltages to motors in a hand controller to provide torques which oppose deflection of the hand controller. Thus, the operator feels the opposing torques which are proportional to the magnitude of the constrained forces and moments. The force feedback loop may be opened to selectively provide a passive control loop. In either the active or passive mode, the hand controller position signals may be selectively mapped to either gripper position signals or gripper velocity signals in order to control movement of the gripper in the desired manner.

Abstract: An exhaust extraction system for use in a welding work station is provided which operates to exhaust the noxious fumes from the welding site when the welding operation is being carried out and for a limited period thereafter. A supply of an inert shielding gas is delivered under pressure to both the welding side and the damper control mechanism. In response to changes in pressure in the supply line of the inert shielding gas, the damper control mechanism is operable to close the damper when the welding machine is deactivated and to open the damper when the welding machine is activated.

Abstract: A carton of the type having; first and second main panels and first and second side panels which are connected to one another so as to articulate between a knocked-down compact configuration and an open sleeve configuration. First and second main flaps hingedly are connected to the first and second main panels respectively and first and second side flaps hingedly connected to the first and second side panels respectively. Each of the flaps has a proximal end adjacent and a distal end remote from its associated main or side panel. Pour spout sub-panels are initially formed as integral parts of adjacent first main and first side flaps and are severable from the remainder of the adjacent first main and first side flaps respectively to form a pour spout in use. The adjacent first main and first side flaps each have marginal edge portions located at their distal end outwardly from the pour spout sub-panels with respect to their associatd first main and first side panels respectively.

Abstract: In a carton loading machine, there is provided a mechanism which will initially displace one row of cylindrical-shaped objects with respect to its adjacent row such that load items in one row are located in a staggered relationship with respect to the load items in the adjacent row. The load items are then displaced into the open end of a container. When the assembled load is substantially fully located within the container, the movement of one row is arrested while the movement of the other row continues until the items of the adjacent rows are arranged in a side-by-side relationship. This serves to permit the width of the accumulated load to be reduced until the load is substantially fully located in a carton and thereafter the load is rearranged to its maximum width to fit in a close fitting relationship within the carton.
