A method for changing a light bulb in a parking light pole, comprising disposing a housing on the top of a light pole for holding a lamp holder having a lamp disposed therein, holding the lamp holder in the housing by urging the lamp holder downward, removing the lamp holder by urging a removal apparatus up through an annulus in the center of the light pole to urge a plurality of pivoting members outward and away from the bottom surface of the lamp holder to allow the lamp holder to fall and be captured by the removal apparatus, replacing the lamp holder by disposing the lamp holder in an installation device, urging the installation device upward such that the lamp holder causes the pivoting members to urge outward, urging the installation device down in the annulus to allow the lamp holder to be urged downward, and removing the installation device.

A quick-change lighting assembly includes a stationary ring, a plurality of clips, and a compression ring arranged between the stationary ring and the clips. Each clip has a retaining end and moves between a retaining and a releasing position, whereby the retaining end is deflected against the compression member when moving from the retaining position to the releasing position. The compression member can move towards the stationary member from an extended position, such that movement of the clips moves the compression member from the extended position to a first position. The clips accept a flange of a socket assembly, the flange defects the retaining ends from the retaining position to the releasing position until the flange directly engages the compression member and further translates the compression member to a second compressed position and the clips return to the retaining position below the flange.

Quick-change lighting assembly and method of use

A lighting apparatus includes an elongated housing defining an elongated chamber. The housing is mountable at first end to a structure. A fixture includes a receptacle that receives a light bulb. The fixture is configured to be slidably inserted into the housing from inside the structure and positioned within the elongated chamber of the elongated housing outside the structure. An alternate lighting apparatus includes a mounting apparatus having a housing including a receptacle for receiving a light bulb and a body portion connected to the housing. The mounting apparatus is positionable in a first position inside the structure and configured for receiving a light bulb inside the structure, and the mounting apparatus is postionable in a second position wherein the mounting apparatus with the housing and the received light bulb is slidably inserted through a bore in a wall of the structure and the housing is positioned outside the structure.

There is disclosed a catalyst, which catalyst comprises a hydrogenation component comprising chromium, molybdenum, and at least one metal of Group VIII, a crystalline molecular sieve zeolite, and a porous refractory inorganic oxide. Suitable molecular sieve zeolites are those having pore diameters of at least 5 .ANG. (0.5 nm) and containing exchangeable cations, for example, faujasite-type crystalline aluminosilicates, mordenite-type crystalline aluminosilicates, ZSM-type crystalline aluminosilicates, and AMS-type crystalline metallosilicates. There are also disclosed processes for the hydrodenitrogenation and hydrocracking of a hydrocarbon stream containing a substantial amount of nitrogen compounds, which processes comprise contacting said stream under suitable conditions and in the presence of hydrogen with the aforesaid catalyst.

This invention pertains to a new process for removing metals, especially contaminant metals, from spent catalysts. Also, this invention pertains to a catalyst composite with metals removed by the new process, and to several uses for the catalyst, including as a rejuvenated hydrotreating catalyst. The new process comprises (i) contacting the spent catalyst with a complexing agent with four or more coordinating groups, including at least two carboxylic acid type groups and at least one amino type group, and (ii) separating from the spent catalyst a mixture containing the complexing agent and the removed metals. By this process contaminant metals, like vanadium, are more selectively removed from the spent catalyst than are catalytic metals, like cobalt and molybdenum.
