Abstract: ABSTRACT OF THE DISCLOSURE       A break ignition plug for piston engines wherein an electromagnet acts upon an armature which activates a movable electrode and an ingition  pulse passes through the magnet coil of the electromagnet and a short-circuit path between the electrodes.  The magnetic field which builds-up in the electromagnet causes breaking of the short-circuit path and spark formation,.  At the free end of blade or band springs arranged in spaced relationship from one another at the lengthwise axis of the ignition plug there are provided confronting electrode heads.  The blade springs are retained at the magnet core and freely protrude by means of the electrode ends into a hollow space or chamber formed at a threaded portion of the ignition plug.  At a magnet gap region of the core there are formed at the blade springs armatures which repel one another upon excitation of the electromagnet.

Abstract: SUPERCONDUCTIVE LATCH CIRCUIT          ABSTRACT        This superconductive latch circuit uses superconductive switching devices and can be powered by the same phase of AC power used to power other circuits with which the latch is used.  The latch is comprised of a storage loop including a superconductive switch and an inductor.  It is also comprised of another super-conductive switch through which an AC gate current can flow and whose state determines whether or not the AC current is delivered to the superconductive storage loop.  Information is stored in the loop as the presence and absence of a circulating current of either polarity.  In a variation of this latch, an output of the sense circuit which detects the state of the storage loop if fed back as a control signal to the superconductive switch in the storage loop and also as one input to an AND gate to which a SET signal is also applied.  AC power is switched to the storage loop when both inputs to the AND circuit are simul-taneously present.  In another variation, the signal which is fed back from the sense circuit is an input to an OR gate, whose output is the control signal to the switch in the storage loop.  This latch reliably holds data when the AC power diminishes to zero, and also when the AC power changes polarity.

Abstract: ABSTRACT          APPLYING MARKING MATERIALS TO SURFACES      A method and apparatus for marking road surfaces, runways etc.   Marking material, normally a heat fusable solid in particulate form, is passed from a hopper (10) into a duct (18) where it is mixed with hot pressurised gas from a burner (20), the heat from the gas causing the marking material to partially melt.  The marking material is then directed along a flight tube (22) from which it is expelled onto the surface (24) being marked.  When the material cools the particles fuse together leaving a durable marking on the road surface.  The apparatus is mounted on a vehicle (80) in such a way that markings may be applied on either side of the vehicle.      Control of the flow of marking material is by variable aperture venturi valves (40), as is control of flow of pigment and, when necessary, of purging material.
