Abstract: A motorized fire and smoke damper for an air passage is disclosed. The damper includes a wrap spring clutch used to automatically open and close a multifold curtain to define an opening in the passage. The clutch is normally connected to a stationary member by a fusible link, which restrains a portion of the clutch to enable the clutch to transmit torque to rotate a windup pulley and thereby raise or open the curtain. In the event of fire, the fusible link melts, whereupon the spring clutch no longer transmits torque and the pulley automatically freewheels to lower or close a raised curtain under its own weight or by spring bias. The passage opening is then closed. When desired, the air passage can be reopened by energizing the clutch to rotate it until it engages an adjacent finger, at which point the spring clutch can again transmit torque to the pulley and open the curtain.

Abstract: An improved interliner for fabric articles such as neckbands, collars, cuffs for garments such as shirts and the like. The interliner includes a fabric having a heat responsive permanent adhesive disposed on one surface and on the opposite surface another heat responsive adhesive which serves solely as a fabrication aid and acts as a temporary bonding agent. The permanent adhesive may be employed to bond the interliner to an outer face ply of fabric, thereby imparting form stability and wrinkle resistance to the article despite repeated laundering or dry cleaning. The temporary adhesive adheres to the other face ply for ease of assembly of the garment structure. Alternatively, the permanent adhesive may be used to bind the interliner to a second interliner to impart greater resilience and shape retentive qualities to the fabric structure.

Abstract: A breakerless magneto ignition system having a stator assembly including an ignition coil and core. A solid state gate turn-off switch (GTO) is connected by its anode-cathode electrodes in circuit with the primary winding of the ignition coil for conducting primary current. A solid state switching component is connected in circuit with the control electrode or gate of the GTO and with a capacitor which is charged by current generated in the primary winding in one direction as a result of magneto rotation. The stator assembly includes a trigger coil circumferentially spaced from a leg of the core of the ignition coil a distance approximately equal to the edge distance of the magneto to provide a trigger pulse.

Abstract: Breakerless capacitor discharge ignition system for internal combustion engines in which a charge coil and ignition coil are disposed on ferromagnetic core. A changing flux is established by rotation of permanent magnets past the core. The charge coil is connected to charge a capacitor in circuit with a silicon controlled rectifier (SCR) for discharging the capacitor through the primary winding of an ignition transformer. The charge coil and transformer are wound on the core such that voltages of opposite polarity are simultaneously induced therein by the changing magnetic flux. A half way voltage of one polarity charges the capacitor and a voltage of opposite polarity induced in the secondary winding by the changing magnetic flux triggers the SCR to its conductive state discharging voltage stored on said capacitor through the primary winding of the ignition coil.

Abstract: Self-wringing mop includes a compressible head of sponge rubber or the like and a wringing mechanism which comprises a presser plate pivotable into compressive engagement with the mop head, an operating lever pivotally mounted on the mop handle, a cam lever pivotally connected to the operating lever and a cam disposed on the end of the cam lever such that actuation of the operating handle causes the cam to reciprocate over the surface of the presser plate while pivotally urging the presser plate into compressive engagement with the mop head.
