Abstract: An automatic electric cigar lighter for automobiles and the like having a socket and an ignitor plug receivable in the socket. The plug comprises a manually operable part carrying an electric heating element which can be electrically connected to the socket circuit, the latter having a normally open heat-responsive switch that becomes closed normally-open the manually operable part is first pushed to a deep position in the socket. The socket has a grounding circuit and a "hot" contact that is engageable with a cooperable contact on the plug to effect the electrical circuit through the heating element.

Abstract: A high production method and apparatus by which flat, ribbon-like resistance wire stock is fed between male and female die rolls to produce ribbed or grooved strips which can be spiral wound into electrical heating coils of the type used in cigar lighters, ignitor plugs and the like. The ribbing or grooving of the ribbon enables the nesting of adjoining convolutions to be had. The imparting of the ribbed configuration to the ribbon is effected prior to the cutting and winding of the same into the spiral coil. In accomplishing this, cooperable male and female rolls, turning in opposite directions, engage opposite sides of, and rib the ribbon and thereafter cut it into lengths while it is still moving, this being done at a high production rate. After an annealing process, the cut strips of ribbon can be fed to a coiling machine which will coil them into a spiral shape. The feeding, confining, grooving and cutting procedures are automatically, sequentially and continuously carried out quickly and expeditiously.

Abstract: A high production method and apparatus which utilizes ribbon-like resistance wire to produce spiral wound electrical heating coils as used in cigar lighters, ignitor plugs and the like. Nesting of adjoining convolutions, if desired, can be effected by first imparting a transverse, ribbed configuration to the ribbon prior to the winding of the same into the spiral coil. In accomplishing this transverse configuring, cooperable male and female rolls, turning in opposite directions, form the ribbon and simultaneously cut it into lengths at a high production rate. After an annealing process, the cut strips of ribbon are fed to a coiling machine which has a notched arbor that receives end portions of the strips and coils the latter into a spiral shape while restraint is imposed on the strips. The feeding, confining, winding and ejection procedures involving the strips are automatically, sequentially carried out at a high production rate.

Abstract: An automatic electric cigar lighter, and especially a cigar lighter igniting unit as used for automobiles and the like. The cigar lighter has a holder which presents an outwardly facing socket, and embraces a unique ignitor plug that is received and stored in the socket. At its inner end the plug has a heating element for electrical connection in the circuit of a heat-responsive switch which is also carried by the plug. The latter comprises a manually operable part by which the heat-responsive switch can be closed to complete the heating circuit through the element. A bimetallic member is also carried by the plug, being engageable with one of the switch parts and normally having a circuit-opening position wherein it maintains the one switch part separated from the other. The member is shifted to a closed-circuit position when the plug is actuated. In both positions it receives radiant heat when the heating element is incandescent.

Abstract: The transfer properties of aqueous printing inks are improved by including in the ink formulation a complex of a polyethylene oxide, a urea, and an alkali metal salt.

Abstract: A system for decorating cylindrical cans each having one open end including a curing section which receives the decorated cans with the decorations uncured. In the curing section the cans move through a preheat chamber where can temperature is elevated. The heated cans then move through a drying chamber where flames from gas and air fed burner heads impinge directly on the exterior of the can for curing of the decorations. Thereafter the cans pass through a cooling chamber and then exit from the curing section.The preheat chamber is heated by the burners in the heating chamber. These burners are disposed so that the flame jets are directed downstream at an angle of approximately 13.degree. with respect to lines normal to the path of travel for the cans. The burners are arranged in two parallel arrays disposed one above the other. As the cans travel between these arrays flame impingement on the cans is interrupted.

Abstract: A transfer arm assembly for transferring an exposed lithographic plate from a film negative drawer to a delivery belt system for delivering the plate to a photoprocessor which develops the plate is provided. The transfer arm assembly includes vacuum arms which contact the upper and non-emulsion side of the plate when the plate lies flat on the film negative drawer (or vacuum frame) and deliver the plate in an inverted position on top of the belts in a plane parallel to, but above the plane of the plate on the film negative drawer. A latchable arm is provided in the transfer arm system to enable pivoting of the arm about a first axis for a first portion of its rotation, and then about a second axis for a second portion of its rotation to enable the arms and plate carried thereby to be inverted from a first plane to a second parallel, but spaced plane.

A V-belt is secured to the open-mesh fabric to center and guide the belt wherein the V-belt is guided by suitable guide slots in suitable guide members which require no adjustments for guiding. The V-belt is vulcanized to a strip of cotton tape, and the strip is, in turn, sewn to the open-mesh belt by a high temperature-resistant thread. In one embodiment, a single V-belt is centrally located on the belt. In a second embodiment, two V-belts are located adjacent to the respective opposite edges of the belt. In a narrow conveyor belt, a single V-belt can be provided at one edge of the conveyor belt.

Abstract: A continuous motion decorator is provided with mandrels pivotally mounted to a carrier wheel and radially positioned by a stationary cam.

Abstract: A mechanical vibrator or tapper is shown in which a high intensity permanent magnet armature moves within the field of a coil of wire wound about the magnet. The magnet is guided for reciprocal motion within a spool containing the winding and strikes impact pads at opposite ends of the central spool opening. The magnet consists of two permanent magnets bonded to one another with like poles facing one another and is freely movable within the spool opening and is guided therein. A permanent magnet is fixed at one end of the spool opening and forces the permanent magnet assembly to reverse its motion after the magnet field of the winding drives the armature magnet against the impact pad at that end of the spool opening, and the magnetic field of the coil goes to zero. An oscillator circuit for driving the system is contained on printed circuit boards mounted within the housing which encloses the vibrator structure. The housing is crimped together in its final assembly.
