Abstract: A door stop is provided herein that includes a base section positioned at least partially offset from a door, a forward section extending from the base section, an intermediate section extending from the base section, and a rear section. A retainment zone is defined between the base section, the forward section, and the intermediate section.

Abstract: A mounting hardware assembly is provided herein that includes a bracket having first and second sections. The first and second sections are coupled to one another by a weakened portion. A jamb flange and a wall flange are each defined by the first section. The wall flange is perpendicularly offset from the jamb flange at a common edge. First and second flange apertures are defined by the jamb flange. An elongated body is defined by the second section. A support flange extends at least partially along the elongated body. The support flange is offset from the elongated body. A plurality of openings are defined by the elongated body. The plurality openings includes at least first and second openings. The first opening and the first flange aperture at least partially align when the second opening and the second flange aperture are at least partially aligned.

Abstract: An attachment member is provided herein that includes a base portion configured to be positioned between a first panel and a second panel. A first side portion and a second side portion are respectively positioned on opposing sides of the base portion, the first side portion defining first and second arms and the second side portion defining third and fourth arms, wherein each of the first arm, the second arm, the third arm, and the fourth arm define a non-linear boundary.

Abstract: A jamb mounting bracket for a door or window that includes a jamb flange and a wall flange connected at right angles along an edge. The jamb flange includes one or more keyhole slots extending away from the edge from a narrow portion to an enlarged portion. The jamb flange can be installed on a jamb after the jamb has been placed in the wall opening by placing the enlarged portion of the keyhole slot over a pre-installed fastener in the outer side of the jamb and then sliding the jamb flange inwardly until the shank of the fastener is in the narrow portion of the slot. Marks and score lines on the bracket can be used to plumb and properly position the bracket fasteners. Transverse slots extending from the keyhole slot can be used to lock a fastener at a given position along the keyhole slot. Removable tabs position the bracket at the edge of a wall opening.

Abstract: The excision of sample spots from a gel or membrane by pressing a cutting tool terminating in a hollow cylinder against the gel or membrane supported on a rigid surface is made more reliable by interposing a relatively pliable, intermediate layer on the side of the surface facing the gel or membrane. The pliability of the intermediate layer compensates for any irregularity or misalignment of the cutting edge of the cylinder relative to the gel or membrane.

Abstract: A controller (30) based chromatography system (2) especially designed for flexibility of operation with ease of use and an icon based control panel (32), has a number of function panels (34), each having a function key (36), one or more indicator indicia (40) in the form of icons, letters or numbers, and associated indicator lights (38). A switching valve (4) is used to provide a mixture of two or more solvents (6, 8) to a peristaltic pump (12). The cyclic nature of the pump and mixer can create a resonant condition resulting in poor quality information from the UV monitor (20). The system minimizes this by the judicious selection of the total cycle time T for the switching valve. This can be done using a random number manipulated in a manner to come up with each time T. Alternatively, an irrational number is combined with the pulsation frequency of the pump to create each time T.

Abstract: A fraction collector includes a base unit and a turntable rotatably mounted on the base unit for supporting a plurality of collection tubes. The upper horizontal surface of the base unit includes a receptacle which is disposed to collect fluids discharged onto the base unit. The turntable is enclosed and includes a discharge port which is aligned over the receptacle when the turntable is mounted on the base unit. In this way, fluids which are intentionally or unintentionally discharged into the turntable will be collected in the receptacle 46. Receptacle 46 also includes a discharge port which may be connected to a disposal site, typically by flexible tubing.
