Abstract: A staircase kit comprises a plurality of side panels and a plurality of inner and outer reinforcing panels disposed in layered arrangement over the side panels. The side panels and inner and outer reinforcing panels have preformed holes extending axially therethrough. The side panels are disposed in stacked relation to one another to form a plurality of module joints there between. Likewise, the inner reinforcing panels are disposable in overlapping relationship to the module joints. The inner reinforcing panels form a plurality of inner panel joints that are preferably disposed in staggered relationship to the module joints. The outer reinforcing panels are disposed in overlapping relationship to the inner panel joints to form a plurality of outer panel joints that are disposed in staggered relationship to the inner panel joints.

Abstract: Provided is a curved staircase installed between upper and lower levels of a building structure. The curved staircase may be configured as an “outside radius free-standing” version, an “inside radius free-stranding” version, or as an “entirely free-standing” version using a plurality of step modules disposed in stacked relationship to one another. The step modules may be configured in single-step and/or dual-step versions. Each one of the step modules has at least one side panel and at least one riser assembly which comprises a tread ledger and a front riser. A tread is mounted on the tread ledger and side panel of each of the step modules. Each of the treads is also supported by the front riser of the immediately lower adjacent one of the step modules. Inner and outer reinforcing panels are disposed in overlapping relationship to the side panel to interconnect the step modules.

Abstract: A vehicle maintenance calendar with a personalization portion and a scheduling portion wherein the scheduling portion has at least one recommended vehicle maintenance service printed on a particular date. The personalization portion and the scheduling portion may be secured together using sewing, staples, adhesives, tape, spiral bound, Velcro™, tacks, brads, prongs, glue, pins, paper clips, and so on. Printed on a page is the personalization portion that includes a photograph, the date of purchase of the vehicle, the type of vehicle purchased, the name of the seller/dealership of the vehicle, and contact information for the seller/dealership. The photograph shows the vehicle, an owner of the vehicle, and background environment that the owner is familiar with and finds pleasing. A customer inducement appendix is attached to the personalization portion in the calendar. The customer inducement appendix comprises a picture, wherein the picture includes a vehicle owner superimposed on a vehicle.

Abstract: Provided as a curved staircase which extends between upper and lower levels of a building structure. The building structure has a plurality of spaced vertical wall studs. The curved staircase comprises a plurality of step modules each including a side panel, a front riser and a back riser. Each of the step modules is disposed in stacked relationship to one another to define a plurality of module joints. Each one of the step modules includes a tread which is mounted on the back riser and side panel as well as on the front riser of the next lowest step module. Inner and outer reinforcing panels are disposed in overlapping relationship to the step modules in order to interconnect the step modules.

Abstract: An apparatus and method is provided for forming a dual radius arch frame structure. The apparatus includes a longitudinal member having a centerline and centerpoint. A laterally adjustable support is further included which has one end attached to the centerpoint of the longitudinal member in a perpendicular orientation and a vertical support attached to a distal end of the laterally adjustable support. A left outer form is provided which has a generally semi-circular shaped arch centered and oriented about a left pivot axis located on the centerline a predetermined distance from the centerpoint. A right outer form is also provided which has a generally semi-circular shaped arch centered and oriented about a right pivot axis located on the centerline a predetermined distance from the centerpoint. Additionally, an arched shaped center cord is adapted to be connected to a receiving edge of the left outer form and of the right outer form in a tangentially continuous manner.

Abstract: A glass composition for chemical tempering includes oxides in wt % ranges of: SiO2 60 to 75; Al2O3 18 to 28; Li2O 3 to 9; Na2O 0 to 3; K2O 0 to 0.5; CaO 0 to 3; MgO 0 to 3; ZrO2 0 to 3; where MgO+CaO is 0 to 6 wt %; Al2O3+ZrO2 is 18 to 28 wt %, and Na2O+K2O is 0.05 to 3.00 wt %. The glass has a log 10 viscosity temperature in the temperature range of 1328° F. (720° C.) to 1499° F. (815° C.); a liquidus temperature in the temperature range of 2437° F. (1336° C.) to 2575° F. (1413° C.), and a log 7.6 softening point temperature in the temperature range of 1544° F. (840° C.) to 1724° F. (940° C.). The chemically tempered glass has, among other properties, an abraded modulus of rupture of 72 to 78 KPSI, and a modulus of rupture of 76 to 112 KPSI.

Abstract: A power transmission unit for coupling a prime mover to a vehicle, in particular a bicycle. The unit has a clutch assembly, a gear train, and a freewheel mechanism. The output shaft of the prime mover is connected to the input side of the clutch assembly. The output of the clutch assembly is connected to the input side of the gear train. The output side of the gear train is connected to the freewheel mechanism. The freewheel mechanism is connected to a first sprocket wheel. The first sprocket wheel and a second sprocket wheel are mounted together on a common freewheel which in turn is mounted on the crankshaft of the bicycle. The second sprocket wheel is connected to the rear wheel of the bicycle. In the absence of power from the prime mover, the bicycle may be used in a conventional manner. When in use, the prime mover drives the rear wheel of the bicycle via the clutch assembly, gear train, freewheel mechanism, sprocket wheels and the rear wheel.
