Abstract: ABSTRACT OF THE DISCLOSURE   To protect electrical three-phase machines from damage on the appearance of an unbalanced load between the phases, so-called negative sequence current protection is used.  Conventional measurement of the negative sequence current takes place in filters which contain frequency dependent LC components.  Frequency variations in a three-phase supply, because of an unbalanced frequency response for harmonics in the three phase filters, may lead to an erroneous indication of negative sequence current. The invention provides a novel method for determining both the positive sequence and the negative sequence currents to a three-phase load.  For grounded systems the zero-sequence current is eliminated.Measuring each phase current (IR , IS , IT) and the phase sequence, the positive sequence and/or negative sequence current are/is determined as the solution of an equation derived in advance from the electrical relationships between the phase currents.  The invention also relates to a device for carrying out the method.

Abstract: LATERALLY YIELDABLE HITCH POLE FOR TRAILING VEHICLES    Abstract A laterally yieldable or "bendable" hitch pole is provided for the steering mechanism of a trailing vehicle to minimize or prevent breakage of the hitch pole during sharp turns negotiated by the draft vehicle, especially during backing of the trailer.  The invention is espe-cially applicable to trailers having steering mechanisms of the Ackerman type.  The hitch pole is typically swing-able between right and left stops and breakage or other damage occurs when the pole encounters one or the other of the stops and turning forces are still applied.  The invention provides a two-piece hitch pole having its end-to-end parts connected in such manner as to enable "bend-ing" of the hitch pole in those situations with subsequent recovery of the pole to its normal attitude.

Abstract: ABSTRACT OF DISCLOSURE                          EDDY PUMP          A pump is provided with a vortex generating member which rotates about a central axis to generate a vortex column of liquid which has a rotary velocity and which is directed to the pump inlet. At the pump inlet, this energy is dissipated into the ambient liquid causing an inward flow of liquid swirling in an opposite direction into and through the pump inlet for discharge through a pump outlet.  These opposite directions  liquid flow through the pump inlet results in the term "eddy pump".  The preferred vortex generating member has a plurality of outer liquid inlets leading to passageways of reducing cross section which causes the liquid to increase in velocity as the liquid flows radially inwardly toward the axis and liquid streams are combined tangentially at the axis.  Each of the accelerating streams is identical and they add and combine with one another to create the axially flowing vortex column of liquid.

Abstract: 21         51,245 ABSTRACT OF THE DISCLOSURE   The  kinetic  energy  generated  by  the  rapidly moving contact and coupled operating mechanism of a tripped circuit breaker or similar apparatus is dissipated by a shock-absorbing assembly comprising a stack of metal plates and interposed leaf springs which is mounted on a station-ary part of the breaker and is struck by a lever fastened to  the  main  operating  shaft  of  the  breaker  operating mechanism.  The metal plates are movable toward and away from one another due to the resiliency of the leaf springs and the resulting multiple-impacts between the plates and advancing  breaker  lever  produces  a  momentum  exchange phenomenon which quickly dissipates the kinetic energy and brings the breaker operating mechanism and movable contact to a smooth stop.  The multiple-impact assembly provides a compact shock absorbing means that is especially adapted for use in medium voltage circuit breakers  (5 to 35 KV rating)  of various types which is not  only durable  and efficient but very inexpensive and reliable.  The improved shock absorber is also adapted for use in guns and the like which require a suitable means for counteracting the recoil produced when the gun is fired.

Abstract: ABSTRACT OF THE DISCLOSURE      An autotransfusion system for collecting and salvaging blood from a patient's body cavity and for returning it to the patient includes a collection bottle which is detachably connected by an arrangement of ports and an adapter to a source of suction as well as to a conduit from the patient.  When the bottle is connected to the system the suction draws the blood into the bottle.  When the bottle has been filled and it is desired to return the blood to the patient or for further processing before returning it to the patient the container is easily detached and may be connected to an intravenous delivery set. During reinfusion blood may continue to be collected by the system by replacing the original container with another container.  The system may be operated by suction from commonly available fittings in hospital environments or may be connected to a thoracic drainage system to utilize the suction from that system to operate the autotransfusion device.  The system may be formed from molded plastic materials and is adapted for disposable one-time use.

Abstract: Abstract of the Disclosure A system for dynamically partitioning processors in a multiprocessor system intercoupled by a network utilizes, in association with each processor, a network accessible, locally changeable memory section.   An available one of a number of common dynamic group addresses in each of the memories is reserved for a subgroup for the performance of subtasks within an overall task, and members of the group are designated as they receive messages to be processed.  The members then locally update status words which establish membership, group validity and semaphore conditions, so that transactions may be initiated, coordinated and terminated with minimum involvement of processors that have no relevant subtasks.  When the full task is completed the dynamic group is relinquished for use when a new task is to be undertaken. The system enables many tasks to be carried out concurrently with higher intercommunication efficiency.
