IPC: H04L7/02
Filed: 1991-06-25
Abstract: In a clock recovery circuit, a received APSK signal is sampled at a frequency N times higher than the transmitted clock in response to a first clock from a local clock source, and quantized into orthogonal digital APSK samples. An envelope of the orthogonal APSK digital samples is detected (3) and phase correlations are detected (5) between the envelope and locally generated orthogonal sinusoidal signals and averaged by a low-pass filter (6). The arctangent between the low-pass filtered orthogonal signals is detected (7) and applied to a subtracter (8). A threshold comparator (9) compares the subtracter output with N successive values. A digital V.C.O. (10) is supplied with an output signal from the comparator (9) to generate a sample clock fc at a frequency 1/N of the frequency of the first clock fs for sampling the digital samples from the A/D converter (1). A phase difference is detected by a phase comparator (12) between the second clock fc and the sample clock fc, the phase difference being applied to the subtracter (8) in which the difference between it and the arctangent is determined. The V.C.O. (10) controls the timing of the sample clock in response to the first clock fs in accordance with the output of the threshold comparator (9).

Title: Procedure for the preparation of microporous ceramic membranes for the separation of gas and liquid mixtures
Inventor: MAIER WILHELM F
IPC: C04B41/81
Filed: 1992-05-11
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.  Themembranes are of porous structure with a narrow pore size distribution of pores, where the majority of the pores have meters 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.

Abstract: rotational control apparatus in the form of fan clutches (C) are disclosed including a first, fric-tion disc portion (12) splined on a hub (20) in turn rotatably mounted on a shaft (24). The friction disc portion (12) is reciprocal between a first position ro-tatably related to the facing (52) of a sheave (50) ro-tatably mounted on the hub (20) and a second posi-tion rotatably independent of the sheave (50). In a preferred form, a second friction disc paction (212) is splined on the hub (20) and is reciprocal between a first position rotatably related to the facing (252) of a second sheave (250) rotatably mounted on the hub (20) and rotating at a different rotational speed than sheave (50). By the selective engagement of the fric-tion disc portions (12, 212), the hub (20) will be rotat-ed on the shaft (24) at either the rotational speed of the first sheave (50) or the second sheave (250). In a further preferred form, a second, friction-disc por-tion (112) is rotatably mounted on a reciprocal piston (100) and rotatable relative to the hub (20). Planetary gears (114) are rotated intermediate and in gearing relation between a sun gear (96) fixed on the shaft (24) and an annulus (124) fixed to the hub (20). The second, friction disc por-tion (112) is reciprocal between a first position rotatabty related to a facing (152) secured to the sheave (50) opposite to the facing (52). By the selective engagement of the friction disc portions (12, 112), the hub (20) will be rotated on the shaft (24) at either the rotational speed of the sheave (50) or at a rotational speed different than the sheave (50) and'specifically at a rotational speed de-pendent on the ratio of the planetary drive.
