Abstract: A shower pipe for a rotary drum filter includes first and second parallel rows of spray holes which extend along the length of the pipe. The holes in one row are staggered with respect to the holes in the other row, with both rows being positioned circumferentially in the same quadrant of the pipe. Each spray hole has its own separate fan-shaped diffusion flange extending in a generally parabolic curve from the adjacent hole. Each spray hole may be formed by a premolded plastic sleeve-like insert which is inserted through and seated within prebored holes in a section of the pipe. Each insert defines a spray hole or nozzle for discharging liquid under pressure from the pipe onto its associated diffusion flange. Each diffusion flange member may be premolded to include a female threaded upper portion which threads onto a male threaded projectng portion of the insert extending from the outer wall of the pipe.

Abstract: A bushing, having an elongated conductor substantially encased in insulating material, which extends in sealing relationship through an aperture in a sealed enclosure encasing an electrical apparatus, comprising a conductor having two parts, a first generally cylindrical rod part which is permanently fixed at its proximal end to the electrical apparatus and which extends therefrom toward the aperture, and a second sleeve part having a generally annular passage disposed to circumferentially engage substantially all of the first rod part and thereby provide a conductive path therebetween; a one-piece insulator permanently attached to and substantially encasing the sleeve part of the conductor; means for threadably connecting the two parts of the conductor such that connection and disconnection can be accomplished from outside the enclosure, thereby enabling disconnection of the sleeve part and the insulator from the electrical apparatus without opening the enclosure; and means for sealing the junction of the tw

Abstract: A junction box and battery jumper cable combination for use on vehicles with storage batteries. A cup shaped junction box has a flanged lip for mounting through body panel holes larger than the cup below the lip but smaller than the lip. Pull-in lugs on a screw actuated element are slidable along slots in the cup wall to approach the lip when the screw is actuated to secure the lip and, hence, the junction box to the body. The screw on each pull-in lug is accessible inside the junction box and access to the back side of the mounting area is not essential. Jumper cables adapted to work with the junction box has polarity selective cooperating terminals to assure correct polarity of circuitry. The jumper cables have a spring clamp equipped extension cables to mate with the end of the jumper cables to serve vehicles not equipped with the improved junction box. The junction box is adapted for wiring permanently to the host vehicle battery.

Abstract: An electrical connector 12 for snap-in mounting in an aperture 19 of a panel 13, comprises, a connector body 60 having an outer contact 69 and a passageway 62 receiving an outer conductor 26 of a coaxial cable 21, a grip ring 66 wedged against an internal wall of said passageway 62 and surrounding said outer conductor 26, a center contact 67 having a rearward portion for fitted connection with a center conductor 27 of the coaxial cable 21, a tapered surface 102 on a front end of said connector body 60 for impingement by a complementary connector 14 during mating, a split retention ring 79 surrounding the connector body 60 and being compressible inwardly during insertion into the aperture 19 of said panel 13 and thereafter expansible outwardly to engage the panel 13, a coil spring 83 surrounding the connector body 60 and having one end biased against the connector body 60 and the other end biased against said ring 79 to force the ring 79 against the panel 13, and a flange 77 on the connector body 60 for engagi

Abstract: An under hood and luggage compartment lamp assembly which is adapted to be positioned on a hood or luggage compartment of a vehicle. The lamp assembly comprises a plastic body which has, at one end, a first set of spaced terminals the outer ends of which extend parallel for connection to a plug of a wiring harness and at the other end of a second set of spaced terminals, the outer ends of which are shaped for receiving a wedge based lamp. The inner end of the other of the first set of terminals is bent and resiliently engages the spherical contact of a mercury switch and the inner end of one of the second set of terminals is bent and engages the button contact of the mercury switch. The inner end of the first set of terminals directly engages the inner end of the other of the second set of terminals. The body is provided with projections and recesses for locating the terminals such that they can be dropped in place during assembly. A cover closes the body and mechanically locked to the body.
