Abstract: ABSTRACT OF THE DISCLOSURE        A wall formed of precast concrete blocks with concrete poured within the blocks.  The latter thus serve as a form during concrete pouring and curing and provide finished exterior surfaces.  The use of temporary forms is eliminated.  The blocks are stacked without the use of any mortar in several rows with the blocks of anyone row longitudinally offset the distance of one-half block relative to the blocks of any adjacent row.  The blocks have a length twice their width and their transverse partitions are spaced from the corres-ponding ends of the blocks, so that the transverse partitions are offset from one row to another and the edges of the partitions are exposed and not in contact with one another, so that the poured concrete will entirely surround the partitions, and, when set, positively interlocks all the blocks.  The blocks are also provided with interlocking means to enable proper stacking and to avoid dis-placement during concrete pouring and curing.

Abstract: ABSTRACT OF THE DISCLOSURE          A frame structure for a vehicle which includes two side members connected together by a torsional cross member and at least one other cross member is disclosed.  The torsional cross member is secured to each of the side members in the rear portion of the frame, and cooperates with the side members to provide a liquid-impervious housing for the rear axle assembly of the vehicle.  Torsional cross member has planar components which are permanently connected along adjacent edges to define an included angle of more than 90 degrees.  This provides the frame with multi-dimensional rigidity.  The torsional cross mem-ber combines the function of two members in conventional frame structures, so that the frame structure of the present invention has a lower center of gravity and is lighter than conventional frame structures.

Abstract: Abstract of the Disclosure The circuit includes a signal input circuit having a light emitting diode that is optically coupled to a phototransistor in a signal output circuit comprising a noise suppression circuit and a Schmitt trigger circuit. The noise suppression circuit comprises a switch portion including a transistor switch and a timing portion including a capacitor.  The transistor switch is connected in parallel with the capacitor, and in the quiescent condition of the line isolation circuit, the transistor switch is turned on so as to maintain the capacitor in a discharged condition.  When the light emitting diode is illuminated by an input signal exceeding a particular threshold, the phototransistor is turned on, causing the capacitor thereupon commences.  The Schmitt trigger circuit is connected to the output of the noise suppression circuit, and if the signal is of sufficient amplitude and duration, the charge on the capacitor reaches the level necessary to operate the Schmitt trigger circuit.  Otherwise, the capacitor is discharged by the turning on of the transistor switch responsive to the turning off of the phototransistor.

Abstract: ABSTRACT         The present invention relates to a connector assembly for coaxial cables.  In applications where such a connector must be a sealed connector assembly adapted for use in outdoor applica-tions there the cable and the connector assembly are exposed to the elements prior art connectors have suffered from the disad vantages of being constructed of numerous parts and are expensive to manufacture.  The present invention is directed toward an im-proved environmentally protected connector assembly for coaxial cables, which is relatively simple and economical in construction. is easy to assemble, and effectively prevents the intrusion of water or other deleterious substances to the interior of the eon nector.  According to the invention there is provided a tubular stem insertable between the braided outer conductor and inner in-sulation of the cable and fixedly carrying a collar and rotatably carrying a coupling nut for connection to a compatible connector component.  O-rings provide seals between the coupling nut and the compatible connector and the collar.  A resilient sleeve is re-ceived over the cable and includes inner ribs adjacent to one end to provide a watertight seal with the cable and having at the other end a lip engaging a flange on the collar to provdide a further watertight seal. A retaining shoulder in the sleeve cooperates with an enlarged portion of the insertion end of the stem to retain the sleeve in place and provide further sealing.  A crimp ferrule around the cable serves to clap it on the connector arm.
