摘要:
Apparatus for facilitating the selective lifting of the lid or the seat/lid combination of a two-piece toilet seat assembly comprises (a) a stem member that is adapted to pass through a pre-formed opening in the lid portion of the seat assembly so as to be movably supported by the lid portion, (b) a manually-engagable handle rigidly connected to one end of the stem member, and (c) a latch member radially-extending from the stem member at a location on axially spaced from the handle. During movement (e.g., rotation) of the stem member within the pre-formed opening in the lid portion, the latch member moves between a seat-latching position in which it underlies a portion of the seat portion of the toilet seat assembly, and a second position in which it is spaced from the seat portion. Thus, applying an axial force on the stem will cause the lid and seat portions to pivot away from the toilet basin together when the latch member is in its seat-latching position, and will cause only the lid portion of the assembly to pivot away from the seat portion when the latch is in its second position.

A process for manufacturing a finished lubricant by: a) performing Fischer-Tropsch synthesis on syngas to provide a product stream; b) isolating from said product stream a substantially paraffinic wax feed having less than about 30 ppm total nitrogen and sulfur, and less than about 1 wt % oxygen; c) dewaxing said feed by hydroisomerization dewaxing using a shape selective intermediate pore size molecular sieve comprising a noble metal hydrogenation component, wherein the hydroisomerization temperature is between about 600° F. (315° C.) and about 750° F. (399° C.), to produce an isomerized oil; and d) hydrofinishing said isomerized oil, whereby a lubricating base oil is produced having specific desired properties; and e) blending the lubricating base oil with at least one lubricant additive.

An integrated process for lowering the pour point of Fischer-Tropsch derived wax which comprises (a) collecting separately from a Fischer-Tropsch unit a Fischer-Tropsch wax and a Fischer-Tropsch condensate; (b) pyrolyzing the Fischer-Tropsch wax in a thermal cracking zone under thermal cracking conditions pre-selected to achieve a cracking conversion of the paraffins molecules present in the Fischer-Tropsch wax of at least 10 percent; (c) recovering from the thermal cracking zone a low pour point Fischer-Tropsch derived wax and a Fischer-Tropsch derived overhead product; and (d) mixing at least a portion of the Fischer-Tropsch derived overhead product recovered in step (c) and at least a portion of the Fischer-Tropsch condensate collected in step (a) with at least a portion of the low pour point Fischer-Tropsch derived wax in the proper proportion to produce a Fischer-Tropsch derived waxy product having a pour point equal to or below about 40 degrees C.

A self-securing fastener may include a shaft, a shank may be disposed at a head end of the shaft may have a primary side substantially parallel to an axis of rotation of the shaft and a plurality of secondary sides arranged about the axis of rotation, the primary side and the secondary sides may describe a pattern when viewed from a direction substantially normal to the axis of rotation, an external thread may be disposed substantially helically at a tail end of the shaft distal from the head end, and an appendage may be disposed fixedly to the primary side and extending substantially radially to the axis of rotation, the appendage may have a thrust face substantially normal to the axis of rotation, wherein the shank is prevented substantially from turning when the appendage is inserted in an aperture may have a shape substantially similar to the pattern, the thrust face abuts substantially an edge of the aperture, and a nut may have an internal thread substantially complementary to the external thread is rotated along the shaft.
摘要:
A new method, system and apparatus for mounting mechanically, thermally and electrically light emitting diode (LED), crystals, arrays or packages. The above provides an LED assembly having reduced number of components and costs, superior heat dissipation, mechanical properties and a compact structure. The use of a grid or mesh allows for more efficient and inexpensive removal of heat from one or more LEDs within an LED fixture.
摘要:
The fracturing methods described in the present disclosure provide advantage over the current fracturing methods. The disclosed fracturing methods can change the fracture gradient of the downhole subterranean formation. For example, one or more of the fracture gradients of the low and high stress zones of the downhole subterranean formation can be changed. Furthermore, the methods of present disclosure, in relation to current practices, can decrease the extent and/or degree of fracturing within low stress downhole formations and increase the degree of fracturing within high stress formations.
摘要:
A mobile application for integrating a location sharing event with a messaging platform such as a text messaging or email platform allows users to be prompted about location sharing when at least a part of the message includes location or time information. In one embodiment, the mobile application takes the form of an integrated location sharing application that parses the message to discern the relevant location or time information. The application may also provide a notification of a future event and may optionally generate a location sharing event based on the notification. In another embodiment, the application permits interactive route sharing between at least two computing devices.
