Abstract: An obstacle detecting pig for preliminary inspection of a section of a pipeline travels through the section and determines if there are any restrictions that exceed industry guidelines or that might damage other pigs that require the full bore of the pipe. In a first embodiment, a disk-shaped segmented resilient member (14) is mounted in the body of the pig. Its outside diameter is smaller by a spacing (21) than the inside diameter of the pipeline (15). The spacing is set at the maximum tolerable size of the obstacle encountered. The deformation of the member (14) is transmitted by a linkage (22) to a slider (16) activating a switch system signalling that an obstacle has been encountered. A non-resiliently deformable checkup disk (19) may be provided at the rear end of the pig, to double check that a no-signal passage through the pipe is not due to failure of the switching system. In a particularly preferred embodiment, the resilient member is a disc-shaped detector (46) made from an elastomer and provided at its leading surface with a scratch recording layer (51), for instance a layer of lead which is thin enough to follow resilient deformations of the elastomeric ring (50) as it encounters an obstacle, and return of the ring back to its regular, shape. The scratches caused on the recording layer are evaluated after the passage of the pig through the examined pipeline section. The detector is mounted directly on a slider (44) or the like operating device designed to produce electric signal when an anomaly is encountered. Preferably, the detector (46) is a replaceable element of the pig. The device is structurally simple thus providing low manufacturing and operation costs and simple operation.

Abstract: The system (10) controls reclining and dumping of a seat and the return of the seat back to its upright position depending on the position of the seat. The system (10) has a master unit (6) and a slave unit (8). The master unit (6) has a base plate (12) that attaches to a seat and pivots with respect to the ground. A master lock (90), which attaches to the base plate (12), allows the base plate (12) to pivot only when the lock (90) is unlocked. A master seat plate (70) connected to the seat pivots on the master base plate (12). A memory latch (120) normally secures the base and seat plates together so that pivoting the master plate (12) pivots the seat plate (70) except when the memory latch is not latched. A slave-side mechanical lock (111) connects directly to the seat back, which allows the seat back and the master base plate (12) to pivot only when both the master and slave locks are unlocked. An input/output device (164) unlocks the slave lock when the memory latch unlocks, which allows dumping. The input/output device (164) also unlocks the slave lock (111) when the memory latch (120) on the master lock (90) is unlocked to allow the seat back to dump. The device also permits the entire seat to slide forward when the seat back dumps. A lockout latch (290) on the memory latch (120) senses the position of the seat and prevents the seat back from returning completely to the memory position until the seat slides completely to its pre-dumped, rearward position.

Inventor: MARZ HORST FRITZ
IPC: F04C15/00
Filed: 1997-06-09
Abstract: An improved progressive cavity (pc) pump is provided. In a first aspect, the pc-pump comprises a rotor connected to a motor via a drive shaft that is isolated from the material flowing through the suction chamber of the pump, thereby preventing the pumped material from reaching the joints of the drive shaft through faulty seals. In another aspect, the pc-pump comprises a rotor assembly comprising a rotor shaft that is joined to a rotor member by means of a connecting member featuring a thermally-induced structural failure capability that provides a tamper-proof fail-safe mechanism against overheating. In a preferred embodiment the connecting member is made of low temperature melting alloy that converts into the liquid state at a temperature beyond which the operation of the pump may no longer be safe. If the pump overheats, as a result of deadhead operation or dry pumping, the connecting member melts thus terminating the driving relationship between the rotor shaft and the rotor member. The improved pc-pump is particularly useful for pumping explosives.

Title: Method and apparatus for merging shingled signature streams
Inventor: COLLINS MICHAEL A
IPC: B65H39/04
Filed: 1999-06-21
Abstract: Two shingled streams of signatures are stacked independently of each other in separate stacking bins that are aligned vertically one above the other and also vertically aligned with the collection bin of a re-feeder.      The collection bin is replenished periodically by stopping the shingled streams and unloading the contents of the lower and upper stacking bins to form a combined stack of signatures in the re-feeder collection bin. Signatures in the re-feeder collection bin are delivered by an out-feed conveyor belt in a single reshingled stream of signatures to an in-line processing station. In an alternative embodiment, the stacking bins are laterally separated with respect to each other for separately stacking signatures from two incoming shingled streams that are being output from separate web presses or other independent sources.

Title: Multiple modulus container carrier
Inventor: WEAVER WILLIAM N
IPC: B65B17/02
Filed: 1999-08-25
Abstract: A multi-packaging device capable of carrying containers having a range of diameters. The multi-packaging device is constructed from a plastic sheet having an array of apertures arranged in lateral rows and longitudinal ranks. The plastic sheet contains integral segments of a resilient polymer co-extruded with respect to the plastic sheet or laminated on the plastic sheet. The plastic sheet may also contain a longitudinally arranged line of weakness under the resilient polymer. The resultant structure enables the multi-packaging device to maintain integrity when a large diameter container is inserted into an aperture because the resilient polymer laminate continues to stretch even after the plastic sheet reaches a stress level approaching neck-down.

Patent CA-2295401-A1 (CA)
Inventor: VINCENT RAYMOND A
IPC: E03C1/05
Filed: 2000-01-13
Abstract: An electronic faucet having a spout, a electronically actuated valve, and a microprocessor-based control circuit for operating the valve to enable or disable water flow through the spout. The microprocessor has a control program which includes a calibration routine that uses an infra-red sensor to determine an adjustable setpoint indicative of the signal received from the sensor in the absence of an object in front of the faucet. The microprocessor switches the valve from its closed state to its open state when the signal from the sensor either increases above the setpoint by a selected amount or decreases below the setpoint by a selected amount. This provides a window about the setpoint within which differences between the setpoint and the signal do not result in opening of the valve. Object detection is accomplished using a tracking routine that adjusts the setpoint in an attempt to track the sensor signal. If the sensor signal undergoes a change that is too large to be tracked, then the microprocessor switches on the valve. Once the sensor signal drops back into a range of values about a stored calibration point, the valve is closed. The control circuit is part of an electronics module that is mounted within the spout and that is held in place between the spout tube and the spout housing. The module includes a curved recess having a shape that conforms to the spout tube so that the module is retained in place at its upper end by the spout tube.
