Abstract: Connector device for connecting the lamp circuit of a trailer vehicle with the lamp circuit of a tractor vehicle comprising a circular base member having a hub, circular walls, and different diameter non-conducting plastic rings rotatably disposed one within the other on the base member. Each ring has a recessed metal strip along its underside, a convex dimple, and a positioning hole in its upper surface. Contact riders radially disposed on the base member establish electrical contact with the metal strips of each ring and are connected with conductors which are attachable to the lamp circuit of one of the vehicles. Contactor plates radially disposed on the base member have concave dimples adapted for receiving the convex dimples of the rings. A second set of electrical conductors are connected to the contactor plates and run to the lamp circuit of the other vehicle.

Abstract: A machine for inserting quilting buttons of the type described in U.S. Pat. No. 3,701,174 includes a multiple displacement upper piston mechanism with movable upper button feed means and a dual displacement lower piston mechanism and a movable lower button feed mechanism. Upon an open work bed between the upper and lower mechanisms, a quilt or the like is positioned so that actuation of the machine to pick up button parts and insert them in the quilt causes the two mechanisms to come together on opposite sides of the quilt and for the female button portion to be forced through the quilt, followed by forcing of the male button portion through the female portion. Retraction of the mechanisms leaves the quilting button inserted through the quilt and the mechanisms in condition for another button insertion.

Abstract: An improvement in printing presses wherein main press side frames are provided with circumferential slots about the axis of plate or printing cylinders for receiving sectional or reversible mounting blocks for carrying impression cylinders. The mounting blocks have eccentrically mounted cylinder bearings and adjustment means are provided for precisely locating the blocks in the slots. The Invention provides for ready changing of the press from letterpress to offset or planographic printing.

Abstract: An electrically small, directive, low backlobe broadband antenna is described. The antenna comprises a pair of radiators. Each of the radiators comprises a pair of orthogonally oriented stripline sections carried on a thin substrate. In one embodiment the radiators are carried on separate substrates placed side by side with a small separation. In another embodiment, the radiators are carried on opposite sides of the same substrate. In each of the embodiments, the radiators are mounted adjacent to a ground plane. A first one of the orthogonal sections is spaced from and extends parallel to the ground plane. The second of the orthogonal sections extends from the first section to the ground plane and is adapted at that point for coupling to the center conductor of a coaxial cable. Means are also provided for coupling the outer conductor or shield of the cable to the ground plane. A resistor is further provided coupled between the ground plane and the free end of each of the first sections of the radiators.

Abstract: A delta modulator produces a digital bit stream from an input analog waveform and applies same to bit-averaging circuitry dividing the bit stream into time-frame intervals and computing the average slope per frame. Each average time-frame slope value is transmitted over a communication system as a discrete digital signal and at a receiver each such signal is employed to set the gain of a multi-level integrator and thus incrementally reconstruct the original waveform.

Abstract: Gear drive, more particularly a gear drive for a rotary printing press, wherein there are gear couples each consisting of a male gear, and a female gear, the male gear having rollers instead of teeth, such rollers being seated in sockets, the female gear having sockets which are complementary to the rollers; the rollers being mounted in side plates and by such means that they are held firmly (but resiliently) against the bottoms of their sockets. An alternative design employs sprockets with a roller chain drive.
