Patent CA-2061967-A1 (CA)
Title: Stepless clamp
Inventor: OETIKER HANS
IPC: B25B25/00
Filed: 1992-02-27
Abstract: A clamp structure which is provided with at least one pair of plastically deformable ear-like folds located on opposite sides of a center longitudinal cut in the clamping band and spaced in the circumferential direction by such a distance that they can be plastically deformed simultaneously by the use of a pincer-like tool. The pincer-like tool includes two sets of jaw-like members spaced from one another so as to permit simultaneous engagement of the two ear-like folds of a respective pair. The pincer-like tool may thereby have a relatively fixed center member forming a relatively fixed jaw-like member and two pivotally supported jaw-like members operable to be actuated toward one another. In the alternative, the pincer-like tool may include two sets of jaw-like members pivotally connected with each other whose points of pivotal connection are coupled with each other as also corresponding jaw-like members to assure movement in unison. By simultaneously plastically deforming the two ear-like folds while maintaining their relative position in the circumferential direction, a clamp structure can be realized devoid of any gaps, discontinuities or steps that might otherwise be a source of leakage.

Title: Method and system for cleaning up large oil spills
Inventor: HOLUBOWICZ KAZIMIERZ S
IPC: C02F1/40
Filed: 1992-05-11
Abstract: A METHOD AND SYSTEM FOR CLEANING UP LARGE OIL SPILLS   ABSTRACT        This invention presents a method and system which cleans up and recovers up all from large oil spills.  The method is based on a principle of separation of two liquids, the densities of which are not equal, by accelerating the mixture of the mentioned liquids.  The system uses, as means for the mentioned acceleration, dynamics of a sudden and rapid change of the oily water's flow.  The system sucks the mentioned oily water from the ocean and pumps it through an array of sections, being pipe coils.  An oil is collected from the inner part of these coils and water from the outer part.           This allows to separate the oil from water in a continuous manner and that assures needed efficiency to clean up a large spills of oil - up to hundreds of thousands of tons of crude sucks water together with the mentioned oil gathered from the ocean.

Patent CA-2071359-A1 (CA)
Title: Bale mover cable tensioner
Inventor: REMPEL WILLIAM
IPC: A01D90/08
Filed: 1992-06-16
Abstract: BALE MOVER CABLE TENSIONER ABSTRACT OF THE INVENTION A round bale carrier has an elongate bale support on a front end of which bales are loaded. The loaded bales are then pushed toward the rear of the bale support by a pusher, making room to load a new bale. The pusher is also used to unload the carrier by pushing the bales off the rear end of the carrier. The pusher is driven by a cable wrapped around a winch at the front end of the bale support and a pulley at the rear end. It is retracted by a second cable wound on the winch and leading to the pusher. The two cables are connected to a rotor mounted on the bale pusher, with the pusher advancing cable being connected closer to the axis of the rotor than is the pusher retracting cable. The tensioner accommodates the elongation of the pusher advancing cable and maintains the retracting cable under tension.

Title: Hydroxamic acid containing polymers used as corrosion inhibitors
Inventor: FONG DODD W
IPC: C08L33/04
Filed: 1992-07-23
Abstract: Hydroxamic acid containing low molecular weight polymers have been found to be excellent corrosion inhibitors for iron and steel alloys in contact with industrial waters. When the waters contain hardness ions, such as calcium, magnesium, and mixtures thereof, the waters are preferably treated with combinations of the hydroxamic acid containing polymers and scale inhibiting/dispersing polymers, which polymers do not contain hydroxamic acid functional groups. The hydroxamic acid containing polymers, as well as the combination of hydroxamic acid and scale inhibiting/dispersing polymers may also both be formulated with other corrosion inhibitors.

Patent CA-2077424-A1 (CA)
Title: Lock-Up Clutch Control System of Vehicle Automatic Transmission
Inventor: SAKAGUCHI SHINICHI
IPC: F16H61/14
Filed: 1992-09-02
Abstract: A system for controlling a lock-up clutch of a torque converter in which a target speed ratio of the torque con-verter is determined by carrying out a fuzzy reasoning based on fuzzy production rules using a degree of throttle open-ing, a grade resistance and a current speed ratio as parame-ters.  Then a second fuzzy reasoning is carried out based on second fuzzy production rules using a deviation between the target speed ratio and the current speed ratio and the change of the deviation as parameters to determine a control value such that the lock-up clutch is controlled between a position at which the clutch is fully engaged and a position at which the clutch is fully not engaged including an in-termediate position at which the clutch is partially en-gaged.  With the arrangement, the lock-up control can cope with various vehicle operating conditions so that the driva-bility and fuel consumption is improved while suppressing engine noise.  The arrangement further enables the control that is better matched to the intention, descision-making, and feelings of a human driver.

Title: Cellular-activated remote vehicle starter
Inventor: URMIN STEVEN J
IPC: F02N11/08
Filed: 1993-08-10
Abstract: ABSTRACT   A remote vehicle starter which is combined with a vehicle's cellular phone, using its transmission capabilities to activate an electrical circuit parallel to the vehicle's standard electrical ignition circuit to start the vehicle.  Multiple audio signals restrict random callers from using the remote system and are entered into the remote starter by a remote telephone to enable a start cycle which automatically repeats until the engine starts and which uses vehicle parameters to inhibit engine ignition or to cutoff engine operations. Connected to the vehicle cellular phone, the remote starter limits the number of remote multiple audio signal codes attempting to start the vehicle, and provides an indicator when false remote audio codes have been attempted.  A run timer limits the time the vehicle operates by cutting off power to the engine electrical circuit upon expiration of a preset run-time.  The keypad of the vehicle's cellular phone is used to program the remote security code and to program the run-time for the vehicle.   Other features include a call timer to limit the time random calls could tie up the phone and an audio feedback capability by telephone to indicate the operating status of the vehicle and the operations of the remote starter.
