Patent CA-1051951-A (CA)
Inventor: ADAHAN CARMELI
IPC: B60T8/48

Granted: 1979-04-03
Abstract: ABSTRACT OF THE DISCLOSURE            The specification describes  a modulating pump including a pumping member that is initially operable by a solenoid device in a relatively long full-stroke condition to effect rapid pressure build-up of the fluid supplied to a load, the pumping member being subsequently operated by the solenoid device in a relatively short stroke condition to effect further pressure build-up in the load.          A main spring device normally bias the armature of main solenoid device to achieve the full-stroke operating condition, and when the pressure of the load reaches a value to cause the return force of the main spring to be overcome, a resilient abutment device becomes operable to achieve the desired short stroke pumping condition.  A self commutating pump device is also disclosed.  The modulating pump device is included in a vehicle traction control system, as, for example, an anti-skid traction control system for automatically braking an overrunning driven wheel relative to another driven wheel connected thereto by a differential mechanism.

Abstract: POSITIONING APPARATUS                  ABSTRACT OF THE DISCLOSURE      Apparatus for reciprocatively positioning an article or work object (e.g. an inspection sample or test probe) in precise relation to two separated work stations.  The article to be positioned is held in a first carrier having a cam-follower attachment.  The first carrier is supported shift-ably on a second carrier.  The second carrier can be recip-rocated perpendicular to the plane of the work stations.  The cam follower of the first carrier is captured movably in a cam track groove of a stationary plate having two cam track grooves associated with respective said stations.  A two-position rotatable cam forms a linking channel between the two tracks.  Upon completion of a work operation at one of the stations the second carrier is reciprocated.  This moves the cam follower of the first carrier up along one track and one associated surface of the cam to a reversing point above and beyond that surface, and then down along another surface of the cam into the other track; thereby transferring the work object to the other work station.  The follower move-ment along said another surface rotates the cam so that on a next reciprocation of the second carrier the cam follower rides up said another surface to said reversing point and down the one surface into the one track; reversely tipping the cam to its original position as it rides along said one surface.

Abstract: IMPROVED METHODS FOR CARBURIZING STEEL PARTS                 ABSTRACT OF THE DISCLOSURE          The present invention relates to a method of carburizing and carbonitriding steel parts in the work chamber of a vestibule furnace with a substantially reduced consumption of carbon sources by exposing such parts to a gaseous carbon source such as natural gas while supplying an inert gas to the vestibule at a sufficient rate to control the entry of atmospheric decarburizing agents into the work chamber and to maintain the oxygen content in the vestibule at safe levels, below a minimum level required for supporting combustion or for allowing local puffs and explosions.          The vestibule furnace may be of the batch of continuous type.          In addition, the carbon potential of the atmosphere within the work chamber of the furnace is preferably continuously sensed and in response to such sensed carbon potential, the flow of natural gas to the work chamber is controlled so as to maintain the carbon potential at a predetermined value.

Abstract: PROGRESSIVE DISPLACEMENT OF RESIDUAL WATER PAST SHUT-IN WELLS PREPARATORY TO TERTIARY OIL RECOVERY Abstract of the Disclosure In the oil-bearing formation wherein primary production has been exhausted and secondary recovery by waterflooding is exhausted or about exhausted, the residual brine is removed by progressive displacement. In this displacement a centrally disposed injection well or, preferably, lineal injection walls are utilized for the initial injection of preflush fluid with the immediately adjacent production and/or injection wells being shut in. After a specified slug of preflush has been injected, a series of chemical slugs is injected followed by drive fluid. After displacement of the residual brine has been effected out past the adjacent shutin wells, as evidenced by the arrival of the preflush, they are utilized as production wells. After oil sweep to these wells is complete, they are used as injection wells and the procedure is moved another step outward.
