Abstract: 14                  48,436 ABSTRACT OF THE DISCLOSURE     Surface currents are induced in dynamoelectric machine rotor body portions by negative sequence currents during unbalanced load operation.   The surface currents are shunted away from retaining rings which are respect-ively situated on opposite axial ends of the rotor and function to restrain radial movement of conductor end turn portions  which  extend  axially beyond  the  rotor's body portion.   The retaining rings are shrink fitted on both ends of the rotor's body portion so as to structurally extend that body portion in both axial directions. Shunt-ing the rotor surface currents away from the retaining rings provides an operating temperature therein of suffi-ciently low level to maintain high electrical joint integ-rity between the retaining ring and rotor.  A mantle of highly conductive material surrounds both retaining rings in  intimate  electrical  contact  therewith.   The  mantle thickness is at least one-half depth of electrical current penetration for the rotor surface current's frequencies. The mantle is electrically connected to the rotor body portion preferably through interference fits with radial extensions  of  slot wedges are situated in longitudinal slots formed in the rotor body radially outside electrical conductors disposed in those slots.  The wedges constitute electrically conductive material and provide longitudinal electrical conductor retention in the rotor slots during high speed rotor rotation.  Components joined through the interference fit include the mantle and the wedges' radial extensions.   A material softer and of higher electrical 48,436 conductivity  than  either of those joined components is preferably interposed as a plating material on either or both components.

Abstract: Abstract of the Disclosure A latching system for a luggage article in which an elongate latch console attaches interiorly to one section of the article for cooperation with a hasp assembly on another section of the article.  The latch console includes a pair of left-hand latches which pivot in a counterclockwise direction from hasp-engaging to hasp-disengaging positions and a pair of right-hand latches which pivot in a clockwise direction from hasp-engaging to hasp-disengaging positions.  Slide rods within the console are connected between the latches, and a central swiveling actuator  moves the latches from their hasp-engaging to their hasp-disengaging positions responsive to movement from the actuator from a rest position.  Springs return the latches, slide rods and actuator to their intial positions when the actuator is released.  A combination lock is provided to lock the actuator in the rest position and the latches are mounted for movement independently of the slide rods when the hasps are disengaged to allow the hasps to be re-engaged with the latches even when the actuator is locked.

Abstract: BACK-FLOW PREVENTION VALVE David E. Hanson And Martin E. Frenkel ABSTRACT OF THE DISCLOSURE A back-flow prevention valve assembly is disclosed for use with a vacuum pump or the like and employes a valve element movable between positions opening or closing a passageway through the assembly. In the event of pump failure, a control valve, which is operated by fluid from the pressure side of the pump, vents ambient air behind the valve element to assist it in mov-ing rapidly to the closed position to prevent backflow. After resumption of pumping, a controlled withdrawal of ambient air behind the valve element delays opening of the valve until the pump has created a sufficient vacuum to minimize influx of air upstream when the valve opens.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus is provided (Fig. 2) for a two phase gas and liquid mixture contact in an absorption tower or reactor (10') having at least one auxiliary bed (22) dis-posed above the main bed (21).  Each auxiliary bed has separate liquid and gas bypasses (24, 23) comprising hollow tubing of relatively different lengths extending through the auxiliary bed (22).  The gas bypass tubing (23) projects to a greater height above the auxiliary bed (22) than the liquid bypass tubing (24).  This tubing by-pass arrangement allows for a low pressure drop bypass of the auxiliary bed to the main bed by the liquid and gas when the auxiliary bed becomes fouled, whereby the appara-tus life is substantially prolonged.

Abstract: ABSTRACT         In a switched capacitor filter of a first-order responsive to a filter input signal for producing a filter output signal by carrying out sampling operation at a predetermined sampling rate by the use of switching circuit, a capacitor, and an integrating circuit, a voltage divider produces a voltage divided signal in response to the filter input signal to reduce a total capacitance determined by capacitances of the capacitor and the integrating circuit.  The voltage divided signal is sampled by the switching circuit to be sent to the integrating circuit at the sampling rate through the capacitor.  The integrating circuit produces the filter output signal as a result of integration.  In addition, an additional switched capacitor filter of a first-order is connected in cascade to the filter to form a switched capacitor filter of a second-order.  The additional filter comprises an additional voltage divider for voltage dividing an output signal of the additional filter to deliver an additional voltage divided signal to the filter and the additional filter.

Abstract: ABSTRACT OF DISCLOSURE      A cargo restraining device for a palletized load including a platform for receiving a pallet with a load of cargo thereon, and a vertical frame at one end of the platform.  A handle is pivotally secured to the frame and connected to a horizontally-extending member which is movable to place it in frictional con-tact with a floor or supporting surface.  The device is partic-ulary adapted for use with the metal, channeled floor of a re-frigerated carrier vehicle.    When the pallet is placed on the platform, it is locked in place by a serrated member which engages a cross-tie of the pal-let.  The pallet can then only be released by disengaging the teeth of the serrated member which is accomplished by moving a lever resiliently coupled to the serrated member.      To lock the pallet and platform to the floor, the handle is pushed downwardly while at the same time pushing the frame toward the load.  Movement of the handle which pivots about a hinge piv-otally connected to the frame, moves the horizontally-extending member into contact with the supporting surface and at the same time lifts and tilts the platform, which adds an augmented down-ward force on the horizontally-extending member in contact with the supporting surface.  The base of the horizontally-extending member preferably comprises or is covered with a rubber surface, so that it frictionally engages the floor or supporting surface.          Movement of the handle also locks the vertically-extending member in the extended position so that pallet is restrained from move-ment.
