A surgical apparatus for coagulating and cutting tissue includes a handle assembly and a tool cartridge. The tool cartridge includes electrically conductive movable tools, such as jaws and a blade, for cutting tissue. The jaws and blade each are connected to a transmission to facilitate movement. Multiple sheaths are used to encompass and protect the transmissions. Slidable grips are disposed outside of the sheaths and operatively connected to the transmissions that are disposed within the sheaths. At least one lever is supported by the handle assembly and engagable with the grips to facilitate movement of the grips, and thus, the tools.

A power supply apparatus includes an air path extending longitudinally, a fan that blows air into the air path in a direction intersecting a longitudinal direction of the air path, and a plurality of electronic components arranged in the longitudinal direction. Each of the electronic components is cooled by air passing through the air path. With this configuration, it is possible to efficiently cool the electronic components without compromising the flexibility of arrangement of the various electronic components. Also, a dust removal operation can be readily performed without the possibility of damaging the fan.

An adjustable patio cover and storm protection device capable of remote operation which acts as a security screen that prevents access through a doorway or window to which it is coupled, reduces the amount of light able to pass through the doorway or window, and also acts as a storm barricade when in its closed or down / vertical position, and which acts as an awning or sun shade that provides shade for the area in front of the door or window to which it is coupled when it is in its open or up / horizontal position.

Duct sound damper for deliberate reduction of sound waves for a flow machine, particularly for a compressor, with a housing having at least one horizontally extending acoustically reflective back wall and at least one front cover plate. At least one flow channel connected together through inlet opening and outlet opening is enclosed by at least one damper member reducing the sound. The damper member includes horizontal axial stringers, circumferential stringers, the front cover plate, at least one sound-insulating metal element extending horizontal to the flow-guiding cross section, and the acoustically reflective back wall.

A lighting and / or signalling device arranged so as to provide at least a first photometric function and a second photometric function, wherein the device comprises at least one moveable element on which at least the first photometric function is installed and the movement of which is subject to the operation of the second photometric function.

A rake for a litter box for collecting pet excrements, the litter box containing a bottom surface, a front wall, a rear wall, a first and second sidewall to define a litter chamber for holding a supply of litter, the rake includes a bar having first and second ends and extends from the first sidewall to the second sidewall and is movable between the front and rear walls. The bar includes a plurality of tines. A rake support is attached to the bar for supporting the first and second ends of the bar for slideable movement between the front and rear walls. A rake arm is connected to the first and second ends of the bar for slideably engaging the rake supports, such that said bar is selectively connectable to the rake supports without using fasteners.

A system for connecting a shaft (5) to a joint (1), which system includes a shaft journal (10) that is connected to the shaft (5), and a sleeve (4) that is connected to a hub of the joint (1), the sleeve (4) having a shaft-side first opening section (7), a joint-side second opening section (8), and a first radial stop section (14), and the shaft journal (10) having a shaft-side first shaft-journal section (11), a joint-side second shaft-journal section (12), and a second radial stop section (15) for delimiting the insertion path of the shaft journal (10) in the sleeve (4).

A liquid propelled rocket engine comprising a unique pintle injector, radial injector plate and ablative insert to improve combustion stability and reduce harmonic disturbance within the chamber. The injector plate is generally in the shape of a ring surrounding a combination spud and pintle injector, the two allowing at least one liquid propellant and one liquid oxidizer to be injected into the chamber. The injector plate has an array of injectors for injecting liquid propellant into the chamber and a series of cavities within allowing the harmonic disturbance to be damped and providing a more stable combustion environment. The number of cavities and the unique pintle injector's length and width are chosen to reduce harmonic disturbance in the longitudinal, radial and lateral modes. A method for designing engine components and tuning harmonic frequencies within a combustion chamber is also disclosed.

A lighting and / or signalling device arranged so as to provide at least a first photometric function and a second photometric function, wherein the device comprises at least one moveable element on which at least the first photometric function is installed and the movement of which is subject to the operation of the second photometric function.
