Abstract: A printer has one or more tractor sets for continuously feeding paper along first and second paper paths. One tractor set may be pivoted between positions for feeding paper from the front or bottom of the printer along the first paper path. Where one tractor set is used, it may be removed from the first feed path and disposed along the second paper path to feed paper along the second paper path for printing. Where two tractor sets are provided, the second set is disposed along the second paper path to feed the paper along the second path for printing. The tractor sets are detachable and usable in each of the three tractor set feed positions. Other features include eccentric bearings, resilient roller assemblies, an integrally molded mainframe and a cartridge assembly having a one-way ribbon advance clutch and a tensioning device before the mobius loop.

Abstract: To avoid danger of fuel leakage into bilges of a vessel's hull, the fuel feed pipe from the fuel supply to the vessel's engine carburetor is enclosed within a cylindrical casing sealed at one end to a fitting on the carburetor. At its other end the casing is sealed to an aperture in the hull, the feed pipe extending externally of the hull between the aperture and a container enclosing the fuel supply. Alternatively the casing is sealed at its other end directly to the container. The carburetor may have an annular fuel feed chamber with adjustable fuel orifices connected to the feed pipe through a scroll valve linked to the carburetor throttle valve.

Abstract: The cooling system of the present invention directs a cooling mist onto the condenser coils of a conventional refrigerant charged central air conditioning unit. The mist comprises a mixture of tap water and condensate. The condensate is collected from the runoff of evaporation coils. A sensing unit is provided at the condenser coil return conduit for sensing a rise in refrigerant temperature and thereby causing the cooling mist to be directed onto the condenser coils.

Abstract: A device for providing a cavity in a bun for receiving a filling such as a sausage comprises a heating probe adapted to be inserted into a bun to compress the material of the bun to form the cavity and to toast the surface of the cavity so that the cavity remains after removal of the probe therefrom and locating means in the form of a cradle for locating a bun in alignment with the heating probe. Relative reciprocable movement between the probe and the locating means causes the probe to be inserted into and removed from a bun located in the locating means.
