Abstract: ABSTRACT OF THE INVENTION      A method of dewatering an aqueous suspension by concurrently subjecting the aqueous suspension to the action of a sonic or ultrasonic field and an electrical field so as to remove the water from the suspension.  The suspension is moved into a dewatering chamber between opposing electrodes one of which is permeable to water.  The sonic or ultrasonic field is then applied to the suspension concurrently with the electrical field, at a frequency and amplitude adapted to cause water to separate from the suspension particles.  The concurrently applied electrical field between the electrodes causes the particles to migrate away from the permeable electrode and water to migrate toward the permeable electrode.  Water is then removed through the permeable electrode.  The method requires less energy to remove a unit of water, has a faster rate of water removal and achieves a lower moisture content than if only an electrical field or acoustical field were used separately or in sequence.

Abstract: Abstract of the Disclosure Double Staggered Ladder Circuit A double-coupled ladder circuit for a traveling-wave tube has been a slow-wave circuit formed of a pair of combs, each cut from a single piece of metal. Transverse grooves are cut in each piece to form teeth and axial grooves are cut in the ends of the teeth.  The two combs are joined at teeth ends to form a ladder with the transverse grooves aligned to form cavities and the axial grooves aligned to form a beam passageway Coupling apertures are cut in both sides of a first set of alternating ladder rungs and a second set of apertures cut in the comb backing members over the second, interleaved, set of rungs. Thus, each cavity is coupled on two opposite sides to its preceding cavity and on the two remaining sides to its following cavity.  The double coupling provides increased bandwidth and efficiency.  Finally, side plates are affixed to cover the apertures, com-plete the cavity walls and form the vacuum envelope.

Abstract: CONTROL ROD DRIVELINE AND GRAPPLE                 ABSTRACT OF THE DISCLOSURE A control rod driveline and grapple is dis-closed for placement between a control rod drive and a nuclear reactor control rod containing poison for para-sitic neutron absorption required for reactor shutdown. The control rod is provided with an enlarged cylindrical handle which terminates in an upwardly extending rod to provide a grapple point for the driveline.  The grapple mechanism includes a tension rod which receives the upwardly extending handle and is provided with a lower annular flange.  A plurality of preferably six grapple segments surround and grip the control rod handle. Each grapple rod segment grips the flange on the tension rod at an interior upper annular indentation, bears against the enlarged cylindrical handle at an interme-diate annulus and captures the upwardly flaring frustum shaped handle at a lower and complementary female seg-ment.  The tension rods and grapple segments are sur-rounded by and encased within a cylinder.  The cylinder terminates immediately and outward extending annulus at the lower portion of the grapple segments.  Excursion of the tension rod relative to the encasing cylinder causes rod release at the handle by permitting the grapple segments to pivot outwardly and about the annulus on the tension rod so as to open the lower defined frus-tum shaped annulus and drop the rod.  Relative movement between the tension rod and cylinder can occur either due to electromagnetic release of the tension rod within defined limits of travel or differential thermal expan-sion as between the tension rod and cylinder as where the reactor exceeds design thermal limits.

Abstract: 1,041,685. Automatic temperature control. HOVAL ING. G. HERZOG & CO. April 14, 1965 [April 21, 1964], No. 16071/65. Heading G3R. In a system in which boiler water is circulated for space heating and in heat exchange relationship with a hot water tank producing a running hot water supply, a thermostatic changeover switch sets a liquid or gaseous fuel burner in operation when the temperature of the boiler water falls below a predetermined value and opens a valve in the supply pipe from the boiler to the space heating when the temperature of the boiler water exceeds the predetermined value and solid fuel firing is in use. A control circuit is described which may be switched to a "solid fuel only" condition to introduce a draught regulator and start a circulating pump for the room heating water. A valve in the circulating system remains closed, however, to prevent room heating until the water in the running hot water tank reaches say 55‹C. at which temperature a thermostat opens the valve. A room thermostat then controls electrothermal operation of the valve to maintain the room at say 20‹C. Rise in the temperature of the boiler water above say 75‹C. is prevented by a boiler thermostat over-riding the room thermostat and opening the valve in the circulating system. If the system is switched to a "burner only (Winter)" state, fuel is supplied to the burner and there is no solid fuel firing or draught. Automatic control of the running hot water and room temperatures is otherwise as for solid fuel firing but the boiler thermostat controls the burner instead of the valve in the circulating system. If, in an attempt to rise room temperature in cold weather the valve opens sufficiently to operate a limit switch, this renders the boiler water thermostat ineffective so that the circulating water temperature can rise up to the limit, say 90‹C., set by an additional safety thermostate controlling the burner. When the system is switched to a "burner only (Summer)" state, the circulating pump is switched off and running hot water only is provided.

Abstract: During the process of binding a bale of crop material with binding twine in a crop baler, malfunction of the knotter (54) is checked once upon completion of the binding sequence for one bale, and then a second time after the twine has been prepared by the knotter for formation of the next bale. The monitoring system is particularly appropriate for a double knotting mechanism in which each knotter operates through two complete operating cycles during each actuation thereof, a first cycle to complete a knot associated with the just finished bale, and a second cycle to complete a knot in two separate strands of twine to prepare the same for the next successive bale. The position of a slack takeup arm moved by the binding twine between a number of positions during the double knotting sequence is monitored by the electronic portion of the system, including a computer, so that if the takeup arm is located improperly at one of the critical checking times in the sequence, such condition is reported to the operator through a visual display in the tractor which tows the baler.
