Abstract: 9D-HL-14359 ABSTRACT OF THE DISCLOSURE A transmission is disclosed for providing drive to a washing machine aqitator and basket to produce slow speed agitator oscillation and relatively high speed rotation of the basket for spin extraction.  The trans-mission input shaft is driven by a drive motor and operated for either reversing or unidirectional rotation to produce the agitator oscillation and basket spin, respectively.  The input shaft is drivingly connected to an agitator power shaft through reduction gearing carried in a gear case, while the gear case is secured to the washing machine basket. A clutch-brake arrangement alternatively causes braking of the gear case to the transmission housing or couples the gear case to the input shaft to produce the high speed drive of the basket through the gear case, or alternatively producing a low speed oscillation of the agitator by drive through the reduction gearing.

Abstract: ABSTRACT            The invention disclosed concerns a procedure for purifying waste water containing chlorinated phenolic compounds, such as the bleaching effluent of a sulphate cellulose pulp mill. The purifi-cation is carried out biologically in a floating  bed reactor which  has been inoculated with a bacterial population decom-posing chlorinated phenolic compounds and wherein the bacteria use the floating particles for affixing substrate. The purifi-cation takes place in the reactor under anaerobic conditions, and the water removed from the reactor may be oxygenated or aerated and conducted to a supplementary aerobic purifying step, where amother floating bed reactor or a bark filter is used.

Abstract: SHOE SOLE CONSTRUCTION     ABSTRACT      A shoe sole having a tread defining a longitudinally orientated concavity with the lower extremities of the sole embodied in downwardly and outwardly disposed flex-ible lugs to cushion the foot against impact loads. An imaginary plane containing the lowermost points of inner and outer lugs, adjacent each side of the sole, inter-sects a projection of the sole edge at an acute angle. Accordingly, the lugs may readily flex relative to other sole components for cushioning purposes. Rows of lugs spaced inwardly from the sole edges are of a lesser vertical dimension than the outermost lugs and serve to supplement cushioning. A web extends between some of the outer lugs to reinforce same against load deflection. Further, the outer lugs may be of non-uniform lateral dimension at the heel portion of the sole.

Abstract: ABSTRACT OF THE DISCLOSURE          A composite cruciform structure adapted for securely joining two or more intersecting fiber based composite struc-tural members of an airframe and the like, is disclosed.  A first bundle of graphite or other fibers of high strength is intimately interwoven with a second bundle of like fibers, with each bundle of fibers extending in a different direction and being aligned with the general longitudinal axis of a respec-tive first and second composite structural member.  A third bundle of fibers is interwoven with both the first and second bundles of fibers to form the cruciform structure.  The bundles of fibers are reinforced with a suitable cured resin.  The cruciform structure may comprise an integral part of the respective structural members, or may be attached thereto by splicing.  The cruciform allows for substantially even distri-bution of structural loads regardless of the direction of the corresponding load force vectors, and is most advantageously utilized in the construction of high strength and low weight airframes.

One or more rollers of elastomeric material are positioned in the chamber with the rollers in rolling contact with the concentric cylindrical surfaces, Teeth project into the annular chamber from both surfaces and engage the rollers from diametrically opposite positions to transmit torque from the drive to the driven member. Excessive torque causes the rollers to compress between the two engaging teeth, the roller passing between the teeth and allowing the drive member to rotate relative to the driven member.

Abstract: Abstract of the Disclosure A portable radio communication device comprises a battery, a DC-DC converter for stepping up the battery voltage and a processing circuit for detecting and processing received signals.  The processing circuit has a presetting terminal and a power supply terminal to which the stepped-up voltage is applied.          A presetting circuit is connected between the output of the DC converter and the presetting terminal and is arranged to set the processing circuit in its initial state in response to the stepped-up voltage.  A power supply switch has a first terminal connected to the battery, a second terminal connected to a reference potential point and a third terminal connected to the input of the presetting circuit either directly or through a low value impedance.  In the "ON" position of the power supply switch the first and second terminals are connected together thereby supplying the battery voltage to the communication device and in the "OFF" switch position the second and third terminals are connected together cutting off the battery voltage.  Additionally and unique to the invention, the provision of a conductive interconnection between the third terminal and the presetting circuit has the effect of reducing the discharge time of the presetting circuit when the switch is switched to the "OFF" position.  This is an improvement over conventional such devices in which the presetting circuit would not have sufficient time to discharge if the switch were turned "OFF" and then "ON" again after a short period of time, the result being that the pro-cessing circuit cannot be set in its initial value.
