Abstract:
A safety sleeve apparatus comprises a safety sleeve encapsulating a fluorescent tube for protecting the fluorescent tube from physical damage and for preventing the tube from sliding out of the sleeve and breaking if the sleeve is tilted from the horizontal during installation of the tube into a pair of lamp sockets. The sleeve protects the tube from damage if the sleeve is struck by a hard object, and creates an airspace around the tube to protect the tube from cold and prevent the escape of fragments from a broken tube. The sleeve has a greater inside diameter than the outside diameter of the tube. An end cap is mounted on each end of the sleeve, and the end cap includes a cylindrical ring extending upright from the edges of a flat end wall. Projections are included in the cylindrical ring and the projections attach to the slots in the ends of the sleeve.
Abstract:
A surgical guiding instrument for use with a chisel and an implant body for insertion into an intervertebral space, included is a shaft with a stop device for delimiting a depth of insertion of the implant body into the intervertebral space. The shaft has a distal end and a proximal end, the implant body being arranged at the distal end of the shaft and defining two bearing surfaces positionable against the adjacent vertebral bodies, the stop device having at least one stop movably mounted at the distal end of the shaft or on the implant body, the stop having a stop surface pointing in distal direction transversely or substantially transversely to at least one of the bearing surfaces, so that an insertion depth for a surgical machining tool can be set in a simple way.
Abstract:
An implant has two parts, each of which includes a joint surface facing the other part, wherein the joint surfaces are in contact with one another in an implanted state and permit pivoting of the two parts in relation to one another. An instrument for handling the implant includes a holding element for detachably connecting the instrument with each of the two parts of the implant. The instrument further includes a spacer element extending between the parts of the implant when the parts are connected with the instrument and maintaining a distance between the parts, thereby preventing the joint surfaces of the two parts of the implant from contacting each other.
Abstract:
In a kit for an intervertebral implant comprising an upper end plate and a lower end plate for placement on adjacent vertebral bodies, and bearing elements arranged between the end plates for mutually pivotally supporting these, the end plates carrying anchoring projections on their outer sides which face the vertebral bodies, to enable an anchoring of the end plates that is adapted to the anatomical conditions, it is proposed that the kit comprise end plates of a first type, which carry at least one anchoring projection configured as a fin or a rib extending parallel to the direction of insertion of the intervertebral implant, and end plates of a second type whose anchoring projections are different from fins or ribs extending parallel to the direction of insertion, and that the kit contain both end plates of the first type and end plates of the second type for each intervertebral implant. The invention also relates to an intervertebral implant assembled in this manner.
Abstract:
Provided herein are couplings useful in the transfer of liquid fuels from a remote storage reservoir to an on-board fuel tank of a motorized vehicle. There is provided a first coupling which is adapted to be in fluid communication with the interior of a vehicle's fuel tank, and a second coupling which is intended to be in fluid communication with the contents of a remote fuel storage reservoir. The invention also includes a process for charging a fuel reservoir on board of a motorized vehicle from a remote reservoir, wherein the vapor in the fuel reservoir is displaced by an equal volume of fuel delivered from said remote reservoir, and wherein the vapor in said fuel reservoir is simultaneously caused to be transferred to said remote reservoir, thus permitting no escape of the vapor from said fuel reservoir to the surrounding atmosphere. Through use of the present invention, spills of fuel are essentially eliminated, and the escape of vapors from the vehicle's fuel tank are prevented, thus preventing atmospheric hydrocarbon pollution.
Abstract:
A location and ranging system for divers is disclosed, which indicates to a diver the position of, and range to, a boat (or other platform) with respect to the diver's current location. For example, a location and ranging system for divers is disclosed, which includes a transmitter, a receiver module, a display module, and a depth sensor integrated with the receiver module or display module. A diver can attach the display module to a convenient part of the body (e.g., the wrist), or a clipboard or buoyancy compensator. The transmitter is located at the diver's boat, and emits an encoded signal at a frequency suitable for transmission through water. The receiver module is carried by the diver (e.g., attached to the diver's SCUBA gear) and includes three receivers that independently receive the encoded signal from the transmitter. Logic circuitry in the receiver module triangulates the three received signals and derives the transmitter's direction. Also, based on the amplitude of one or more received signals, the logic circuitry can determine the distance to the transmitter. The display module includes a simple readout that displays the diver's depth, the distance to the transmitter/boat, and an arrow that points in the direction of the transmitter/boat. If the transmitter's antenna is submersed but near the water's surface, the logic circuitry in the receiver module can calculate the horizontal distance to the boat (e.g., parallel to the surface) using the depth information derived from the depth sensor and the known distance from the transmitter. Thus, with the direction and distance information directly at hand, the divers know how far they need to travel to reach the boat. As another example, a plurality of transmitters can be permanently located on the sea bed to form a guide path for divers. Also, a plurality of portable transmitters can be placed by divers at strategic locations in a cave, cavern or shipwreck. Consequently, the transmitters can be used to indicate an exit path for the divers, even if their guideline is broken or their visibility is obscured by silt.
Abstract:
A benchtop securing device for securing objects to a table is provided. The benchtop securing device comprises a mounting plate having a table engaging surface adapted to abut a surface of a table, the mounting plate further having an object attaching surface adapted to mount an object thereon, and a sloped member having a sloping surface, the sloped member further being coupled to the mounting plate such that the table can be received between the mounting plate and the sloping surface of the sloped member. The benchtop securing device further comprises a sliding block having a sliding surface that has a slope that substantially matches the slope of the sloping surface of the sloped member, wherein when the sliding surface of the sliding block engages the sloping surface of the sloped member the benchtop securing device becomes securely attached to the table.
