Abstract: An automobile anti-theft device that has its parts straddling over the spoke(s) of a steering wheel, with one side tightly wrapped around by the device, Traditional steering wheel locks, such as the trademarked product The Club®, PTO registration number 872404, allows a maximum of two cuts on the steering wheel to remove the anti-theft device and thus is not a very effective theft deterrent. The present anti-theft device eliminates the two-cuts needed to easily steal because one side of the steering wheel is completely wrapped around, allowing no cuts to be made by the would-be-thieves. Theft can only be attained by extreme force to break the present device, destroying the key/lock mechanism, or chopping away the steering wheel from the steering column.

Abstract: There is disclosed an improved rotatable cylinder lock having a removable lock core. The lock core is removable from the lock housing for locking applications that require the lock to have up to 180° of lock core rotation. The invention is accomplished through the use of a specially designed lock housing, lock core, adapter, and shifter. The lock housing has a cylindrical opening defining a groove and rotational slot. Inserted within the cylindrical opening in the lock housing is an adapter having a stop lug and tumbler block, a shifter having a drive slot, and a lock core having a block restrictor relief. In use, the stop lug on the cylindrical adapter rotatably engages with the rotational slot in the housing while the tumbler block on the adapter rotatably engages with the block restrictor relief on the lock core. The assembly of the present invention thereby permits the lock core to be rotated 180° within the lock housing while also permitting the removal of the lock core.

Abstract: A method measures the concentration of the partial pressure of gases, particularly oxygen, in fluids. Know methods for measurements under rough conditions, e.g., measurement of the oxygen partial pressure in grounds, dumps or in the ground water are completely unsuitable. In the present method as described, in the internal area of a hollow vessel closed off to the outside, whose wall consists at least partially of a gas-specific permeable synthetic material that is in contact with the fluid with its external side, the partial pressure change proportional to the gas concentration is measured as a time-scanning of pressure change or as a change of a pressure-dependent physical variable. The measuring principle is very simple and is particularly suitable for the determination and long-time monitoring of the oxygen concentration and of further gases and can also be used in problematic locations.

Abstract: A method and apparatus for measuring erosion rates of sediments and at high shear stresses due to complex wave action with, or without, a superimposed unidirectional current. Water is forced in a channel past an exposed sediment core sample, which erodes sediments when a critical shear stress has been exceeded. The height of the core sample is adjusted during testing so that the sediment surface remains level with the bottom of the channel as the sediments erode. Complex wave action is simulated by driving tandom piston/cylinder mechanisms with computer-controlled stepper motors. Unidirectional flow, forced by a head difference between two open tanks attached to each end of the channel, may be superimposed on to the complex wave action. Sediment traps may be used to collect bedload sediments. The total erosion rate equals the change in height of the sediment core sample divided by a fixed period of time.

Abstract: A method of synchronizing a crankshaft signal with the stroke cycle of a four-stroke internal combustion engine induces misfiring in a specified engine cylinder, and uses an assumed synchronization to identify the misfiring cylinder. The crankshaft signal is used to identify reference angular positions of the crankshaft intermediate top dead center positions of consecutive cylinders of the engine firing order, and a time difference between successive reference positions is determined. When the assumed synchronization is such that the current rotation of the crankshaft includes the cylinder in which misfiring is induced, the determined time difference is accumulated in a first accumulator; otherwise, the determined time difference is accumulated in a second accumulator. The presence of misfiring causes the two accumulators to diverge in value, and the direction of such divergence is used to determine if the assumed synchronization is correct or incorrect.

An electric pump 14 is turned on when a purge valve 5 is in a closed state and a selector valve 20 is in an open state.

As in the curve A, when a load current final value I2A is equal to or less than the load current initial value I1, it is determined that the gaseous communication state in the purge line between the purge valve 5 and the intake passage is normal.
