Abstract: This electromechanical device with a manual emergency control for opening the door of a safety outfit box on board an aircraft comprises in said box a spring-loaded piston responsive to an electromagnet and having a head shaped to control the movements of registering locking members into or out from their locking position in which they engage a retaining hook engageable in turn with a cross member of a strap carried by the door. Said locking members may consist of balls or small ball-bearings engageable in corresponding holes formed in a sleeve concentric to said piston. Manual control means are provided for actuating said piston from the outside and thus opening the door in case of emergency.

Abstract: Safety Belts for vehicles capable of being positioned in front of a rider on one of the vehicle seats and having parts of the belts which can be temporarily stiffened near to at least one anchoring point thereof and means for guiding said stiffened belt portions at said anchoring points.

Abstract: A composting unit comprising a container mounted in an elevated position for rotation about a substantially horizontal axis, said container being provided with a door through which material can be placed into and removed from the container.

Abstract: An arrangement in a silo for bulk material, comprising a rotating agitator centrally arranged in the silo. The agitator consists of a rotatable disc equipped with at least one rigid paddle which is mounted on the disc for pivoting about an axis which is offset from the central axis of the disc. The swinging of the paddle about the offset pivot axis is effected by actuating means arranged below the disc. When the disc rotates the paddle is resiliently advanced through the material in the silo in a more or less radially extending position depending on the relation between the force imparted to the paddle by the actuating means and the reactive pressure from the contents of the silo. The paddle is pivotally mounted as a lever having two arms which are both exposed to the material in the silo.

Abstract: An apparatus for unloading material such as chips or the like from the bottom of a silo, comprising a conveyer screw which at its inner end is mounted in an annular frame. The frame surrounds a central outlet opening and is rotatable about the central axis of the silo for allowing a swinging motion of the screw along the bottom of the silo. The screw is also mounted for rotation about its longitudinal axis for conveyance of material to the outlet opening, the rotation of the screw being accomplished by a drive means arranged stationary independently of the rotating frame. The power transmission for effecting the rotating and swinging motion of the conveyer screw is accomplished by a transmission means rotatably mounted in the frame, the axis of said transmission means coinciding with said central axis. The frame carries an outlet funnel having an upper opening arranged below the inner end of the screw and a lower opening arranged coaxially with the central axis.

Abstract: This device for steadying, notably against lateral oscillation, a load releasably suspended from an aircraft comprises spring urged wedge members mounted to the load; these wedge members in their steading position penetrate between the upper face of the load and the lower face of the carrier member of the aircraft; these wedge members are retracted manually against the force of their spring means to allow the suspension of the load.

Abstract: The invention provides a disposable insert for a bed-pan or commode, said insert having a seat-portion for fitting over the peripheral area of the supporting member, and within said seat-portion an aperture forming an opening into the receptacle portion of the insert and said seat portion being formed at each side towards its rear with a concavity, and at its rear a central depression said concavities and depression being merged smoothly together and shaped to receive the buttocks and relieve pressure on the posterior bones of a person using the seat.

Abstract: A mobile structure for movement alongside the frames of buildings under construction, capable of raising heavy and also long loads vertically and then laterally onto a floor of said building frame as well as moving loads from the building frame and lowering the same.

Abstract: A ventilation device for ventilating rooms in dwelling locations, or other spaces such as workman's barracks, cold storage and freezing rooms, and the like. An elongated housing is provided with a fan at one end with a reversible motor for controlling the direction of the fan. Heat holdover means comprising a series of heat-exchange plates is positioned in the housing and parallel to the direction of the air flow. Thermostats are provide at both ends of the housing for sensing the temperature of the air flowing by and thereby operating the reversible motor, thus controlling the direction of the fan.

Abstract: A multi-purpose funnel with handle, a flanged rim to prevent overflow and a discharge spout. The funnel comprises two co-axial connections with male thread, the smaller diameter connection having a tubular extension and a rubber seal. Discharge pipes are provided, there pipes can be bushed into the connection spout.

Abstract: A feed device for bulk material, placed in a silo in order to feed out the material stored in the silo. The feed device comprises reciprocally movable means in the form of steps and carrier elements in the form of risers with said steps leading downwards to at least two feeding-out openings. The steps are leading downwards in opposite direction from a highest level to a lowest level located at said openings.

Abstract: A barrier for use as a breakwater or highway safety divider having a reinforced concrete base in which are embedded a plurality of tires extending outwardly of said base and means for joining a plurality of said bases in line.

Abstract: This device for the remote transmission of a plurality of orders through a single control line or channel is intended more particularly for controlling the firing rates and volley-firing limitation of rockets or miscellaneous cartridges notably on aircraft. It comprises essentially a selector-switch control unit and a receiver unit. The device is energized from the common direct-current supply of the aircraft.

Abstract: This cabin gondola or car for ropeway, intended for transporting passengers between two stations on a rope driving a plurality of disconnectable cabins or cars, has an automatic door opening and closing mechanism and the two doors are slidably mounted on the same side of the two-shell cabin housing for closing corresponding apertures somewhat spaced so as to leave a solid wall section therebetween, the mechanism actuating said doors causing same to be superposed to each other against said solid wall portion, a pair of bench-forming seats being disposed transversely and back-to-back, very close to each other, in the tranverse space extending normally to said solid wall portion.

Abstract: A manhole frame with adjustment screws for raising and lowering said frame has in its inner surface pockets or recesses each communicating with a hole for guiding of the adjustment screws. The recesses serve to receive nuts for the screws and the recesses are shaped so as to permit the sideways of said nuts. The recesses also constitute drainages for the screw holes.
