Abstract: STOVE CONSTRUCTION                     ABSTRACT OF DISCLOSURE         A rectangular stove structure has a stepped top with a sloped intermediate top portion having heated air outlets.          Room air is passed through U-shaped ducts arranged along the inside surfaces of the stove side walls, and firebrick is pro-vided on the floor of the stove structure between these ducts.          Air is drawn into the ducts through a side opening which may have a blower and conduit associated therewith.  The door of the stove has rotary combustion air inlets, and a baffle plate is provided inside the door to provide primary air for the fire, and secondary air for improving air circulation and ventilation inside the stove.  Domestic hot water can be heated at the rear of the stove structure in an annular chamber defined for this purpose at the connection for the exhaust gas flue.  Domestic hot air can be supplemented by a plenum provided on the lower front top, and the plenum receives heated air from the outlets in the sloped intermediate top portion.  Coal can be burned in a novel grate provided in the stove, and a humidifier is hung on a flange at the rear of the stepped top.  All of these improve-ments can be used simultaneously.  A heat radiator plate is mounted to the stove legs.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a magnetic separator which comprises a feed hopper for the raw material which is to be separated, and chutes for separating and discharging respectively, the concentrate and the tailing which have been magnetically separated from each other.  A rotary drum is incorporated into the casing and has separation walls of a non-magnetic material disposed in both sides.  There is thus formed at least one feed separation passageway which extends from the feed hopper on the rotation side of the drum, to the discharge chutes. A series of stationary magnetic poles are disposed at the back of both of the separation walls.  In a preferred embodiment, paddles are constructed on the separation walls on both sides of the feed separation passageway and the paddles are equidistantly spaced in a staggered, opposed arrangement on both sides of the passage-way.  This device allows for efficient magnetic separation of powdered raw ore by dispersing and floating the ores concurrently to the magnetic separation without resulting to any external means to liberate the entraining phenomenon of non-magnetic particles.

Abstract: METHOD OF STITCHING RADIAL TIRES  TO INHIBIT BELT EDGE DISTORTION                  Abstract of the Disclosure A simple but effective method of air stitching, avoiding use of hard roller stitchers at and between the lateral edges of the restrictor belt, minimizes or eliminates the displacement of the cord or wire ends at the edge or edges of the belt.  The restrictor belt, or belt-tread assembly is first disposed about the car-cass.  The carcass is then shaped only sufficiently to contact a narrow zone of the belt, and the transfer ring or other device is removed, thereby leaving the belt supported only by the carcass and free of external restraint.  Thereafter the shaping of the carcass expands the axial width of contact then extending progressively outward of the respective edges.  The shaping pressure within the carcass then is sufficient alone to cohere the carcass to the belt.

Abstract: DANIEL HERBERT WOLF                   ANTI-THEFT PURSE ALARM               ABSTRACT OF THE DISCLOSURE           The alarm includes a movement sensitive trigger mechanism and electronic circuitry responsive to the trigger and adopted to generate an alarm signal when actuated thereby.          The trigger mechanism is an electronic switch comprised of an LED and a photosensitive transistor.  The active surfaces of the devices are normally aligned, the LED being suspended by a wire from a support above the transistor.  Vibration or movement above a given magnitude results in misalignment of the active surfaces which causes the transistor to generate a trigger signal.  The sensitivity of the electronic switch is adjustable by varying the spacing between the active surfaces.  A delay circuit is interposed between the elec-tronic switch and the remainder of the alarm circuitry such that generation of the alarm signal is prevented for a preset time interval after the arming of the device in order to permit the electronic switch to achieve mechanical equilibrium.

Abstract: CUSHIONING DUNNAGE MECHANISM, TRANSFER CART THEREFOR, AND METHOD      ABSTRACT OF THE DISCLOSURE:      A cushioning dunnage producing mechanism which is of relatively compact nature utilizing a single multi-ply roll of sheet-like stock material, such as paper, which is directed through a separating mechanism.  As the stock is pulled off the composite roll, the edges are rolled inwardly in a longi-tudinally convergent chute, into generally superimposed condi-tion.  Pusher means urges the sheet-like stock material laterally toward a confronting surface of the chute.  Then the inwardly rolled webs of stock are passed into a crumpler section where mechanism such as meshed gears attach together the confronting portions of the rolled edges of the stock material generally centrally, in a direction lengthwise thereof, to retain the dunnage product in highly compressible, lightweight pad-like form.  A transfer vehicle is adapted to coact with the dunnage producing mechanism for storing a preselected amount of the pad-like dunnage product on the vehicle, whereupon the vehicle can be moved to a location distant from the dunnage producing mechanism for use at the distant location.   A novel method of producing and transferring the pad-like dunnage is disclosed.
