Abstract: A modified construction for a non-linear or curved staircase employs a technique in which the treads (l7, 30) for the staircase are initially cut to the required shape and size. Flexible plywood boards (l5) of the same length and height as the required stringers are then attached to the treads with the treads positioned in the required locations and orientations so as to create a rigid self-supporting structure formed by the flexible boards (l5) and the attached treads (l7) and risers (l4) where required. The self-supporting structure is then finished by the attachment to the flexible boards of suitable laminations (l9, 20). Housed treads (l7) have the laminations applied to the outer surface of the boards. Exposed end treads (30) have the laminations applied to the inner side of the boards.

Abstract: A filter apparatus (10) and method is provided wherein a filter tank (12) is adapted to receive unfiltered liquid (32). An outlet chamber (26) is located adjacent the bottom wall (18) of the filter tank and is separated therefrom by a perforated plate (24). A filter media (36) is movable across the rear (14), bottom and front (16) walls of the filter tank and accordingly, unfiltered liquid must pass through the filter media as well before entering the outlet chamber. A chain flight assembly (40) is provided which is movable across the filter media along the rear, bottom and front walls of the filter tank. As the chain flight assembly is continuous, a return path is across the top of the tank above the unfiltered liquid. A baffle (61) is provided near the rear wall within the filter tank. This baffle (61) extends sideways to near each side wall (20, 22) of the filter tank, upwardly above the level of the unfiltered liquid within the filter tank and downwardly to a point just above the flights (44) of the chain flight assembly above the filter media at the bottom of the filter tank. A spray header (76) is provided to spray filtered liquid between the rear wall of the filter tank and the baffle to prevent unfiltered liquid from bypassing the bottom of the baffle and entering the outlet chamber without passing through the filter media. Another spray header (72) is provided to wash the chain flight assembly while it passes above the filter tank.

Abstract: There is disclosed herein an automated sample preparation system for chemical assay of samples of materials. The sample preparation system includes a sample preparation chamber (10) which includes a removable cup (12) for taking to the location of solid or very viscous samples. The cup may be attached in sealing relationship to a cap (14) through which extends various utilities such as a mixer/grinder (30) to grind solid samples and mix non-homogeneous samples, an ultrasonic transducer 169 and its associated drive mechanism to homogenize samples and break down particulate matter in slurries, a fill pipe (27) to pump in liquid samples, an effluent pipe (20) in the sump of the cup to allow pumping of samples and solvents and a nozzle (28) to allow liquids to be sprayed against the walls. A sample metering valve (36) associated with the sample preparation chamber allows a known volume of sample to be isolated so that solvent may be pumped in to dilute the sample to a user defined concentration. A reversible pump (84) is coupled by a pair of manifolds (94, 96) which are themselves coupled by solenoid operated valves (e.g., 90, 92, 102, 124, etc.) to   various sources of solvents, pressurized gas (104), vacuum (108), water (112), the sample preparation chamber (12) and the assay system (128). A control system (98) coordinates the operation of all remotely controllable units in the system to allow the user to customize various sample preparation processes.

Abstract: 2.1. Zeolites are microporous crystalline aluminosilicates which are distinguished by a number of particular properties. They have a defined cavity system with orifices of 0.3 to 0.9 nm. They are cation exchangers. In the H form, they have high acidity in the solid state. The hydrophobic character can be controlled by the ratio of silicon to aluminium. They exhibit high thermal stability. These substances were generally prepared only with the addition of organic, structure-controlling compounds to the synthesis mixture. Processes which dispense with the use of these organic substances, for example US 4,257,885, lead only very slowly (after several days) and generally incompletely to the desired product. Furthermore, the occurrence of undesirable secondary phases cannot in general be ruled out. The present invention relates to a purely inorganic synthesis process which virtually completely excludes the formation of secondary phases and which can be carried out in a short time. 2.2. The zeolites prepared by the process according to the invention have a chemical composition which can be described as follows in molar ratios: 0-3M2O : Al2O3 : 15-40SiO2 : 0-40H2O, in which M denotes an alkali metal cation. These zeolites can be subjected to exchange with the aid of a mineral acid, an ammonium compound, other proton donors or other cations. In conjunction with the above chemical composition and the interplanar spacings listed in Table I, the zeolites prepared according to this invention have, in the 29-silicon solid state Mas nuclear resonance spectrum, adsorption bands at about -100, -106, -112 and -116 ppm, based on tetramethylsilane as standard, with the aid of which this novel aluminosilicate can be distinguished from all similar zeolites (Fig. 1 and 2). 2.3. Because of these structural units, the zeolite catalysts prepared according to the invention have a much higher catalytic activity than similar pentasils prepared by conventional methods.  3.
