Abstract: A process for preparing pillared chromium phyllosilicate clay a-olefin catalysts is disclosed This process utilizes palygorskite and sepiolite clays. The pillaring of said clays comprise the steps of: (a) preparing a hydrolyzed first solution by dissolving a chromium salt and a base in water, heating said first solution to a temperature in the range of about 20°C to about 100°C while stirring continuously until the solution reaches a pH in the range of about 1.5 to about 2.5 and thereby producing a master batch; (b) diluting said master batch with water to produce a diluted second solution and heating said diluted second solution to produce a heated second solution; (c) adding a solid clay selected from the group consisting of sepiolites and palagorskites to said heated second solution, and continuing heating; (d) recovering said pillared chain silicate clay; (e) drying said pillared chain silicate clay to form first product; 
     The activation of said clays comprise the steps of: (a) heating said first product at a temperature in the range of about 150°C to about 500 °C and for a time period in the range of about 30 minutes to about 10 hours in an inert atmosphere; (b) thereafter reheating said first product at a temperature in the range of about 500  °  C to about 900  °  C and for a time period in the range of about 1 hour to about 50 hours in an oxidizing atmosphere and recovering said catalyst composition. This results in clay catalysts which polymerize a-olefins.

Abstract: In the production of glass beads from a molten glass material with the aid of shear blades, it is proposed to expose the shear blades to a cold inert gas and subsequently cut glass beads from the glass material emerging from a feeder by means of the cold shear blades. This gaseous cooling circumvents, in particular, the disadvantage of the harmful frost effect which occurs in the case of liquid coolants and greatly reduces heat exhange.

Abstract: The signal multiplier device SMD multiplies two signals I1 and I2 applied to its input terminals and generates a digital pulse signal OUT proportional to the result of this multiplicaiton at a terminal OUT. It includes a first pulse density modulator PDM1 converting I1 to a 1-bit word signal C which controls a switch S to connect I2 either directly or via an invertor I to an input of a second pulse density modulator PDM2, depending on the value of C. 
     The device can be included in a device, e.g. an electric energy meter to measure the integral of the product of I1 and I2 or the power of an electric power signal in case of an electric energy meter, in which case I1 is the voltage signal of the electrical power signal, whilst I2 is the current signal or vice-versa. The number of pulses of the digital pulse signal OUT generated during a predetermined time interval is indicative of the power consumption of a user receiver the electric power signal via the meter.

Abstract: A slant plate type compressor (1) with a variable displacement mechanism is disclosed which comprises a compressor housing enclosing a crank chamber (32). The housing includes a cylinder block (31). A plurality of cylinders (33) are formed for defining compression space in the cylinder block. A piston (20) is slidably fitted with each of the cylinders (33). The stroke of the piston changes in response to the change of the slant angle and defines compression volume in the compression space to change the capacity of the compressor. The position of the top dead center of the piston (20) changes within a certain range in response to the change of the stroke of the piston. A suction chamber (52) and a discharge chamber (53) are enclosed within the compressor housing. A communication path links the crank chamber with the suction chamber. A control valve varies the capacity of the compressor by controlling the link between the crank (32) and the suction chambers (52) through the path. The detecting device (70) is disposed adjacent the cylinder (33) for detecting the position of the top dead center of the piston (20) in the compression space. Therefore, the detecting device can directly detect its displacement correctly. In addition, an inexpensive and simple detecting device can be used.

Abstract: Le transmetteur de pression décrit (10) comprend un transducteur de pression (12) placé dans un logement de transmetteur (14). Le logement de transmetteur (14) comporte une fente ou encoche (20) formant une faille à proximité immédiate d'un bord extérieur (24) du logement. Le bord extérieur (24) reçoit une force de serrage importante provenant d'une bride (16) et il peut fléchir à l'endroit de la faille de façon à réduire la transmission des composantes axiales et radiales de la force de serrage depuis le bord extérieur (24) du logement vers le transducteur (12), cette force risquant d'occasionner des distorsions au transducteur de pression (12). Les forces de serrage inégalement réparties, causées par l'expansion thermique différentielle de la bride (16), des boulons (26) et du logement (14) sont isolées du transducteur (12), réduisant ainsi les erreurs de mesure. En outre, on obtient également une réduction de la transmission des forces radiales d'hystérésis depuis le logement (14) du transmetteur vers le transducteur (12), qui sont causées par le frottement dû au glissement de la bride (16) sur le logement (14) du transmetteur de pression, chacun de ces éléments présentant des coefficients d'expansion thermique différents. Plusieurs types de transducteurs de pression (12), par exemple des transducteurs à cellules capacitives, peuvent être montés dans le logement (14) du transmetteur pour fournir un signal de sortie de pression indicateur de la pression linéaire et différentielle.

Abstract: An arrangement that is intended to be series connected in a line of an electrical circuit for protecting the circuit from an overcurrent, comprises a depletion mode FET (1) that switches the line current and a control device (4) that is connected across a resistance in the line, preferably the channel resistance of the FET (1), and will bias the gate of the FET (1) in response to the voltage difference across the resistance in order to switch the FET off when the arrangement is subjected to an overcurrent in the line. The arrangement has the advantage that since the FET (1) is normally on, there is no initial voltage drop across the arrangement before it becomes conductive so that the arrangement can be substantially linear.

Abstract: A digital virtual earth (DVE) cancellation system which receives a phenomena input signal via multiple sensors (1, 2, 3) representing residual phenomena to be canceled, and has adaptive filters (12, 24, 25) for each of the multiple sensor/actuator pairs, (1, 4, 2, 5, 3, 6) which generate the appropriate cancellation signal (19, 20, 21) for the associated actuator (4, 5, 6). The multiple interacting DVE (MIDVE) algorithm estimates the noise at each sensor (1, 2, 3) by subtracting out the combined effects of each actuator signal (19, 20, 21) from the residual signal (16, 17, 18) at that sensor (1, 2, 3). This estimated noise signal is used to control the adaptive filters (12, 24, 25) associated with the subject actuator (4, 5, 6). These filters (12, 24, 25) receive the estimated noise as input. They then produce the cancellation signals by filtering the estimated noise with the filter weights. These weights are adapted using the residual signal (16, 17, 18) and the estimated noise convolved with the system impulse responses.

Abstract: A method and apparatus are disclosed for predicting the organic carbon content of water discharged from a water purification system. Water is directed from a water source through an oxidation means of the water purification system under substantially steady-state conditions. A reference mode is established, whereby a reference-mode resistivity change is determined. A purification-mode is then established, whereby a purification mode resistivity change is measured. The reference-mode resistivity change and the purification-mode resistivity change are then combined to obtain a purified value which is associated with the carbon content of water discharged from the water purification system, thereby predicting the carbon content of water discharged from the water purification system.
