Abstract: A bicycle assembly includes a frame portion, a component and a shim. The frame portion has a component mounting section. The component has a frame mounting section. The frame mounting section is removably coupled to the component mounting section by a fastener. The shim is mounted between the component mounting section and the frame mounting section on the fastener to space the component a predetermined distance from the frame portion. The shim includes a shim portion and a handle portion. The shim portion includes two shim sections connected together. The shim sections have free ends spaced from each other to form an open ended fastener opening with the fastener selectively received therein. The shim portion has a predetermined thickness in an axial direction of the fastener opening to space the component a predetermined distance from the frame section. The handle portion extends outwardly from the shim portion.

Abstract: A vapor-phase tubular reactor in a shell heat exchanger for removal of the heat of reaction at essentially isothermal conditions has porous wicking surface applied to the external surface of reactor tubes. The porous wicking surface on the reactor tubes draws liquid heat transfer fluid from a reservoir at the bottom of the wicked tube section and provides enhanced evaporative cooling. The invention is particularly useful for highly exothermic reactions or when reaction selectivity is negatively affected by high temperature excursions.

Abstract: A drive belt for a continuously variable transmission having belt discs having an at least partially conical contact surface for enclosing a drive belt between pairs of said discs, which drive belt to this end comprises one or more transverse elements provided with converging side faces intended to come into contact with the contact surface of a belt disc and wherein one or more side faces possess a surface which has protuberances providing a profile, which surface has therein contact faces, defined by the protuberances, for coming into contact with the contact surface of a belt disc, wherein the profile is shaped such that on cross-sectioning parallel to the side face concerned, or after wear of the profile at or down to a level which is located at least thirty percent and at most seventy percent of the profile height beneath the initial profile height, the surface area effectively available for coming into contact with the contact surface of a belt disc lies within the range of forty to sixty percent with r
