A clothes dryer has a heat source, preferably a heat pump, a rotating drum, and means to generate flow of air from the heat source to an inlet in the drum. At least two outlets are separated from each other in the drum to enable higher air flow rates without increase in pressure drop, resulting in reduced drying time.

A scanning camera with a rotating drum has one or more sensors characterized by a non-radial optical axis. With two sensors on opposite sides of the drum and facing in substantially the same direction, stereoscopic recording of a panorama is accomplished as the drum rotates. Rapid rotation of the scanning camera produces panoramic motion picture recording, with the final frame speed dependent on the sensitivity and speed of the sensor, the resolution desired, and the capabilities of the recording device. The preferred embodiment employs rotating fisheye lenses for a substantially fill-sphere field of view. Streamlining of the lens elements on the drum surface is described for quiet operation of the camera, even at high rotation speeds. The rapid rotation of the drum characteristic of motion picture frame rates can improve both the stability and portability of the camera. The gyroscopic effect of the rotating weight of the drum can increase the stability of the camera, and the apparent weight of the camera can be reduced by the lifting effect of aerodynamic elements such as rotors added to the rotating drum. The adjustment of convergence are described that improve the viewing of stereoscopic images. Additional sensors in the same arrangement are used to increase resolution through multiplexed recording of the image data. Recording image information using film, either internal or external to the camera drum, is also described as a cost-effective alternative to digital media storage.

An apparatus and method for bagging ice. The apparatus comprises an ice maker for making ice and a hopper for receiving for receiving the ice from the ice maker. The apparatus further includes a roller drum, operatively associated with the hopper, for measuring the ice and delivering of the ice. The roller drum includes an inner rotating drum. A bag delivery mechanism for placing the ice in a bag is also included, with the bag delivery mechanism including a bag supply mechanism, a fan engaged to open the mouth of the bag to receive the product, and a heat sealer that seals the open mouth of the bag once the bag is filled with the ice. A control device is included that manages and monitors the roller drum and bag delivery mechanism and allows transmission of the collected data to the Internet.

A step apparatus includes a step body that can move between a projecting position where the step body projects from a side surface of the vehicle and a retracted position where the step body is retracted behind the side surface of the vehicle, a drive unit for driving the step body, the drive unit including a rope-shaped member connected to the step body, a rotating drum around which the rope-shaped member is wound, and a drive motor that rotates the rotating drum, and a guide unit for guiding the movement of the step body between the projecting position and the retracted position.

An apparatus for producing an elastomeric nonwoven laminate including a plurality of elastomeric strands joined to a nonwoven web in a controlled distribution is provided. The apparatus includes an extruder for extruding a plurality of elastomeric strands onto a cooled surface of a rotating drum, which transports the strands in parallel alignment to a nip formed between two rollers rotating about parallel axis. The drum transfers the plurality of strands to the nip in a controlled distribution where it is bonded with the nonwoven. The apparatus also includes elements which automate the apparatus for creating the elastomeric nonwoven laminate.

An apparatus and process for making glass soot sheet and sintered glass sheet. Glass soot particles are deposited on a curved deposition surface of a rotating drum to form a soot sheet. The soot sheet is then released from the deposition surface. The soot sheet can be sintered into a consolidated glass. The soot sheet and the sintered glass can be sufficiently long and flexible to be reeled into a roll.

A drum type washing machine, where steam and hot water are supplied to heat wash water, including: a water tub for containing wash water; a rotating drum rotatably mounted in the water tub and having, at a peripheral wall thereof, a plurality of through holes; a heating tank for heating water and generating steam; a water supply unit for supplying water into the water tub and the heating tank; and a steam supply pipe, adapted to guide the steam from the heating tank to the water tub, connected to the water tub In this drum type washing machine, the temperature of wash water can be rapidly increased in accordance with steam and hot water supplied into the water tub. Accordingly, it is possible to reduce the overall wash time while reducing the amount of wash water to be used.
