The present invention relates generally to the use of radiofrequency energy to heat heavy crude oil or both heavy crude oil and subsurface water in situ, thereby enhancing the recovery and handling of such oil. The present invention further relates to methods for applying radiofrequency energy to heavy oils in the reservoir to promote in situ upgrading to facilitate recovery. This invention also relates to systems to apply radiofrequency energy to heavy oils in situ.

A radiofrequency reactor for use in thermally recovering oil and related materials includes a radiofrequency antenna configured to be positioned within a well, where the well is provided within an area in which crude oil exists in the ground. The radiofrequency antenna includes a cylindrically-shaped radiating element for radiating radiofrequency energy into the area in which crude oil exists. The cylindrically-shaped radiating element is configured to allow passage of fluids there through. The radiofrequency reactor also includes a radiofrequency generator electrically coupled to the radiofrequency antenna. The radiofrequency reactor is operable to control the radiofrequency energy generated.

A folding scooter has an unfolded position, suitable for riding the scooter, and a folded position, suitable for storing the scooter. The folding scooter includes a folding mechanism that has a spring-loaded pin.

A tenon joint type space lattice structure having a plurality of lattice units and combining pillar is provided. The lattice unit includes a convex tenon and a concave tenon groove disposed at ends of the lattice to form a tenon-and-groove structure. The tenon of one lattice unit may be embedded within an adjacent tenon groove for connecting the lattice units in series to form a continuously extended layer of lattice units. The continuous structure of lattice units forms a plane layer of a space lattice structure. The combining pillar may be passed perpendicularly through a hollow portion of a lattice unit for connecting plane layers of lattice units stacked one over the other to form a three-dimensional space lattice structure. A heavy filling material may fill the hollow portion of the structure to form a gravity structure.

A liftable support structure for a turf system, the support structure comprising a skeletal framework having an open based structure with upstanding sides and at least two parallel spaced cross beams, the framework defining open subsections, each subsection having a base defining a ledge structure, each subsection supporting a latticework panel that sits on the ledge structure, the framework having a plurality of spaced lifting points and the cross beams defining access to forklift tines.A pallet for natural or artificial turf comprising a structure moulded in foamed plastics to have a closed planar top surface supported by a lattice work of mutually perpendicular walls defining a flexible open base, the structure defining a pair of elongate spaced parallel channels extending across each side to facilitate forklift tine entry.

A locking automobile mat hanger and display device consists of two hanger housings that cooperate with an interchangeable adapter insert to secure a plurality of automobile floor mats. The device includes housings having a retaining portion and an adapter insert, whereby the adapter insert and the retaining portion of the housing create channels in which automobile floor mats may be inserted and retained. The device also has a cutout section in the housings whereby a user may easily grasp and carry the entire mat hanger assembly. The device further contains a hook section disposed on the housings, which allows for the entire mat hanger assembly to be hung from retail displays, and also allows for efficient storage. The label application section of the hanger aids inventory organization.

As one non-limiting example, a foldable mast assembly for a sailing vessel is provided. The foldable mast assembly includes a lower mast section; an intermediate mast section having a lower end foldably coupled to an upper end of the lower mast section; an upper mast section having a lower end foldably coupled to an upper end of the intermediate mast section; and a boom coupled to the lower mast section. A locking device internal the mast assembly is also provided to inhibit folding of the mast assembly.

A new and useful cable plug is provided, that is configured for a socket-plug system connecting a PSU to a load device over a 2 wire cable. The cable plug is selectively moveable to one of a plurality of positions for selecting a predetermined output voltage (or other operational characteristic) for the load device In addition, a new and useful socket is provided, that is configured to mate with the cable plug, to provide the selected output voltage (or other operational characteristic) for the load device.

A wearable tactile display device is disclosed wherein vibrating stimulation pins are located close to each other by means of underlying vibratory actuation piezoelectric bending elements arranged in a cantilever configuration partially overlapping over each other. Optionally, the plane in which the tips of stimulation pins protrude may be a curved surface providing with the ability to comply with a curved human body part such as a finger. Vibratory stimulation can be achieved at close spatial resolution by advantageously reducing the space between adjacent stimulation pins through their ability to engage with different adjacent piezoelectric cantilever bending elements when they are placed at different planes and at additional closer spatial resolution when they are placed at an angle to each other. The programmable controller employed in order to program the pattern of stimulation pin vibrations can be used for generating different amplitudes and frequencies of vibration.

There is provided a transporting apparatus which includes a pair of transporting rollers including drive and driven rollers; a transporting path including a curved portion which changes a transporting direction of the transporting medium; a movable member which is changeable to a first attitude forming an outer side of the curved portion to guide the transporting medium, and a second attitude opening the curved portion not to form the outer side of the curved portion. The movable member has a guiding portion which guides the transporting medium between the pair of transporting rollers, in the first attitude, and a positioning portion which positions the guiding portion with respect to a shaft of the drive roller in the first attitude, and which is separated from the shaft of the drive roller in the second attitude.
