Abstract: LOBULAR SOCKET HEAD FASTENER       WITH SERVICE SLOT     Abstract of the Disclosure There is disclosed a socket head type fastener which employs in addition to a primary, lobular drive socket, an au-xilliary drive tool engaging means in the form of a service slot for the reception of a screwdriver or similar type driving tool.          The service slot enables the fastener to be removed and rein-stalled by a serviceman in the field, when the specific drive tool sized to mate with the lobular socket is not available.         The socket and service slot combination is of a special design in that said socket is of a multi-lobular configuration designed for engagement by a correspondingly shaped multi-lobular tool, where the respective lobes of each will be in engagement over known surface area portions upon driving of the fastener, as determined by industry standards.  The service slot means is provided by a pair of slots which open into the socket through the arcuate wall surfaces of the opposed lobes.  The slots are constructed such that the side walls thereof intersect the ar-cuate surface serving to define the flutes and lobes at locations disposed outwardly of the lobe surface portions which are engaged with the drive tool lobes.  As such the presence of the service slot does not diminish the socket lobe surface area for resis-tive or driven engagement with the tool lobes.

Abstract: SIGNALING TONE TRANSPARENT ECHO SUPPRESSOR     Abstract of the Disclosure An improved echo suppressor for use at intermediate points in a telephone transmission facility, whereat both speech signals and single frequency signaling tones may simultaneously be present, provides voice-switched echo control without af-fecting network signaling. In one mode of operation, during periods of critical signaling tone transmission and while high level or augmented tone is present, such as during dial pulsing, the echo suppressor is automatically disabled and completely transparent to the tone, whereby the signaling tone may pass there-through completely without distortion. In another mode of opera-tion, during periods of continuous low level signaling tone, the tone is blocked from an attenuation control portion of the echo suppressor and is reinserted into the transmission facility there-after, irrespective of the presence or absence of speech energy in the facility. In this manner, whenever SF signaling tone is present at an input to the detector it is present at a corres-ponding output therefrom, and the echo suppressor provides voice-switched echo control and accommodates network signaling without interference to either.

Abstract: BLOW MOLDING MACHINE     ABSTRACT OF THE DISCLOSURE     A blow molding machine for the manufacture of products such as bottles from a continuously extruded parison of plastic material. Two pairs of horizontally reciprocable mold sections are shown which alternately take a parison from a central station and transport it to either of two blow molding stations having vertically movable blow pins. The mold section platens carry laterally extending trimming elements and, when each pair of mold sections returns to retrieve another parison, the trimming elements trim flash from the molded product which hangs from the blow pin. The product is then transported to a delivery station by the trimming elements as the mold sections return to the blow molding station. The platens and blow pin stations are all supported by a verti-cally reciprocable table. As a knife severs the parison held by a pair or mold sections from the extruder and the mold sections start moving toward the mold station, the table lowers to prevent resticking of the material being continuously extruded. One of the platens has four tie bars secured thereto, all of which are below the level of the mold sections, the other ends of these bars carrying a force transfer plate. A reciprocable fluid motor is mounted between the other platen and said plate, the cylinder end of the motor being secured to the platen. A rack and pinion arrangement insures equal movement of the two mold sections.
