Abstract: A polyalkylene glycol is added to a reaction mixture obtained by a condensation reaction of fluorenone with phenol in the presence of ss-mercaptopropionic acid and HCl gas, excess phenol is then distilled off, and the residue is crystallised out from a solvent which is miscible with the polyalkylene glycol used. After recrystallisation and treatment with water, 9,9-bis-(4-hydroxyphenyl)fluorene is obtained in the form of a white crystalline product in a purity of above 99%.

Abstract: Involves a doll able to permit the introduction of cookie type slabs through the mouth, which simulates eating and having been eaten they fall by gravity to the bottom of an internal box, from which they can easily be extracted, while at the same time it reproduces at intervals a series of sounds, in the form of changing phrases, which it emits through an acoustic device connected to an electronic circuit. 
     Outwardly it assumes the conventional form of a baby, and it contains in its interior an electromechanical assembly, including a set of wheels situated in line with the mouth, and when the cookie type slabs are introduced through the latter, they cause their intermittent entrainment and subsequent fall into the internal box.

Abstract: An electromechanical valve apparatus has an electrical winding (54) and a magnetic flux circuit defining a flux path therefor which includes a plurality of adjacent magnetic segments. The segments include a generally cylindrical center segment (31-36) with a fluid passage (52), an end segment (31), an outer segment (44) and a magnetic armature member (82). At least one of the segments is physically translatable within the valve apparatus along the flux path to adjust a portion of one of the magnetic segments that is in the flux path and the extent of an air gap adjacent the translatable segment. 
     The apparatus includes a non-magnetic seat member (44) which is located near or at the point of highest flux density along the longitudinal axis through the electrical winding (54). The armature (82) is preferably an elongated member with its closed end located within the electrical winding near the non-magnetic seat member (44). The seat member (44) and armature (82) are enclosed within a chamber defining body (58) such as the bobbin (56). In an alternative embodiment, a flat disc member (98) is located at the base of the armature (82). The flat disc is retained within the base (88a) of the armature (82a). When no current is flowing in the winding (54), the flat disc member (98) rests against an armature seat (96a) formed in the chamber defining body (58) and prevents leakage of air from the fluid chamber (94). A further alternative embodiment allows ready calibration of the valve apparatus via a calibration fixture adopted to translate one of the magnetic segments within the flux path.

Abstract: Substantially crack-free ceramic articles having less than 5% porosity are prepared in a two-step process starting with a potassium- or cesium- or rubidium-exchanged zeolite or mixtures thereof, the zeolite being characterized in that it has an SiO₂/Al₂O₃ ratio of 3.5:1 to 7.5:1, and calcining it in a first step at a temperature of 900° to 1100°C for a time sufficient to collapse the zeolite framework and provide an amorphous powder. Next, the amorphous powder is formed into a shaped article and the article is sintered in a second step at a temperature of 1150° to 1400°C for a time of 0.5 to 12 hours to give a ceramic article. The principal crystalline phase of the ceramic article is tetragonal leucite when potassium-exchanged zeolite is used. When the zeolite is exchanged with cesium a ceramic article whose principal crystalline phase is pollucite is obtained. When a rubidium-exchanged zeolite is used a ceramic article whose principal crystalline phase is rubidium leucite is obtained. When a potassium/cesium-exchanged zeolite is used a ceramic article having as its principal crystalline phase a leucite/pollucite solid solution is obtained. The addition of pollucite to the leucite article provides a ceramic article whose thermal expansion coefficient can be varied from 2 x 10⁻⁶ to 27 x 10⁻⁶ °C⁻¹ as measured over the range 50° to 700°C.

Abstract: A novel phase-measuring method is described which determines the phase difference between two polarised light beams (21, 22) and is based, in contrast to previously known phase-switching techniques, on a parallel signal evaluation. For this purpose, the light beams are firstly spread by a beam splitter (12) into a plurality of component beam pairs (31, 41) (32, 42) (33, 43) (34, 44) (35, 45), which are focused as a parallel beam bundle (19, 20) by a lens (13) onto light-sensitive sensors (16). A phase shifter (14) and a polarizer (15) are provided between the lens and the sensors. Phase differences in the light beams (21, 22) thus lead to differences in the intensity of the parallel beam bundles (19, 20), which are detected by the sensors (16). The novel method permits a high rate of measurement and accuracy of measurement. <IMAGE>

Abstract: In a method for profiling wooden window frames (3a, 3b), in each case one side of the frame is milled over its entire length at the final depth of penetration (t1) to the predetermined final dimensions by means of an up-milling, first milling tool (1). Shortly after the first milling tool (1) has penetrated completely into the front end of the frame side (3a), a down-milling, second milling tool (2) is brought into engagement with the frame side to be milled and then the frame side is premilled approximately over its entire length with the second milling tool (2). In this method, the premilling is performed at a depth of penetration of the second milling tool (t3) which is a few millimetres less than the final depth of penetration of the first milling tool (t1). Shortly before the second milling tool (2) has reached the rear end of the respectively milled frame side, the second milling tool is set to a depth of penetration (t2) which is reduced by a few tenths of a millimetre in comparison with the final depth of penetration of the first milling tool, in order to avoid splaying of the rear end. <IMAGE>

Abstract: Gas and liquid separation with membranes has either been achieved by organic polymer membranes, which are limited by low temperature stability and a separation mechanism through adsorption or solubility in the membrane matrix, or by inorganic membranes, whose gas and liquid separation efficiency is limited by Knudsen diffusion. The membranes of this invention show a temperature stability up to 500 °C and a gas separation with separation factors better than the Knudsen limit. 
     Continuous microporous inorganic membranes of any desirable thickness can be prepared by e-beam evaporation of metal oxides on a support membrane, which has substantially larger pores than the metal oxide membrane. It is advantageous when the support membrane consists of the same material as the microporous membrane. The membranes are of porous structure with a narrow pore size distribution of pores, where the majority of the pores have diameters smaller than 1 nm. 
     The membranes can be used in all areas of gas and liquid separation, where the selective separation of smaller molecules from mixtures is desired (f.e. gas concentration by removal of water from natural gas, hydrogen from synthesis gas). The membranes can also be used for the concentration of aqueous solutions (fruit juices with retention of aroma compounds, vitamines and other compounds important for the flavor and nutritional value of the juice; biological liquids like lymphe, blood, or others with retention of valuable compounds including small peptides, hormones, antibiotics and others) and for the concentration of organic solutions with retention of molecules larger than the solvent including oligomers and polymers. The membranes can also be used for the concentration of waste water with retention of organic contaminants like phenol resins and coal oil at coking plants. If the membranes have been made catalytically active, the membranes can also be used for the selective and poison resistant conduction of heterogeneously catalyzed three phase reactions by having the reaction gas diffusing through the catalytically active membrane to react at the other side of the membrane with the liquid, consisting of molecules too large to penetrate the pores.
