Title: Preparation of zeolites x and y
IPC: B01J29/08
Filed: 1963-04-03
Abstract: A crystalline aluminosilicate zeolite having the crystal structure common to zeolites X and Y is prepared by forming a frit from an aqueous slurry of clay, alkali metal hydroxide and either silica or a precursor thereof by maintaining the slurry at a temperature of 230-1600 DEG F., the proportions of the reactants in the slurry being as follows:-  Weight ratio total alkali metal oxide : water-free clay 0.95-7.4 : 1  Weight ratio silica/water-free clay 0.01-3.8 : 1, and digesting the frit in water at 180-220 DEG  F., the mole ratio of water : alkali metal oxide being 35-180 : 1, until crystalline alumino-silicate is formed.  The term "crystalline" is used to mean either wholly or partially crystalline. Preferably before digestion the frit is ground to \sT60 mesh and dispersed in water in proportion 3 : 1 parts respectively.  The clay may be a raw uncalcined natural clay; the alkali metal hydroxide is preferably sodium, and silica is supplied as sand, quartz, colloidal silica, silica gel, siliceous earth, alkali metal silicate or ethyl orthosilicate.  To obtain a catalyst material suitable, for example, for cracking hydrocarbons, the alkali metal ions may be exchanged up to 97% by alkaline earth metals, rare earth or transition metals, silver, magnesium ammonium or hydrogen; alternatively, providing the stipulated alkali metal oxide to clay ratio is maintained, at least one of the ions may be included in the initial slurry. The base-exchanged material is used per se as a catalyst or suspended in a matrix of, for example, a clay or a cogel of silica (55-100% weight) and alumina and/or zirconia, the catalyst being air-dried and calcined before use.

Abstract: 875,869. Impedance measurements. NEDERLANDSE ORGANISATIE VOOR TOEGEPAST - NATUURWETEN - SCHAPPELIJK ONDERZOEK TEN BEHOEVE VAN NIJVERHEID, HANDEL EN VERKEER. April 17, 1959 [April 24, 1958], No. 13257/59. Class 37. Capacitance or inductance is measured in a circuit in which the reactive component of the current flowing in a series resonant circuit is measured by means of a synchronous detector. The reactive component of the current falls rapidly to zero as resonance is approached, in contrast to the slowly varying resultant current. A circuit described for measuring an unknown capacitance C1 comprises series resonant circuit L1, C1 connected across a cable K having a self capacitance C2, and a source E having a frequency variable between 0.5 and 2.0 Mc/s. Capacitor C3 compensates for the current flowing through C2. The voltage U3 developed across C4 is displaced in phase by 90 degrees from the current in L1, C1 and has a component due to the reactive current in L1, C1 which is either in phase or in anti-phase with voltages U1, U1<SP>1> across the centre-tapped secondary winding of transformer T2. The resultant sum and difference voltages E1 and E2 of U3 and U1 and U1<SP>1> are amplified, rectified and subtracted, the resultant voltage being proportional only to the reactive component of the current in L1, C1 and being zero at resonance.

Filed: 1970-03-20
Abstract: 1,269,747. Self adaptive equalizers. NORTH AMERICAN ROCKWELL CORP. 20 March, 1970 [21 April, 1969], No. 13740/70. Heading H4R. In an adaptive equalizer for the correction of received digital data signals a correction signal Yi is generated and subtracted from the received signal to derive a corrected signal Sc, from which the received digital signal is derived by a decision circuit 57. The correction signal is derived from a digital transversal filter arrangement which synthesizes the impulse response of the transmission system, and is fed with the output of the digital decision circuit to effectively synthesize the amplitudes h 0 , h 1 , h 2 , ..., h n , of the received signal at the signal sampling points. The amplitudes h 1  to h n , corresponding to post pulse interference, are subtracted from the received signal to provide the corrected signal Sc, and the amplitude of the main pulse is subtracted from the corrected signal, in subtractor 73r, to provide an error signal which is fed to the correlators 53, 53a, ... 53n to be correlated with the received corrected signal, fed through the shift register 52, in order to provide correction of the impulse response values so as to tend to reduce the error signal to zero. Also described is a similar system, Fig. 8 (not shown) for reception of data signals modulated on quadrature channels, which includes generation of correction signals due to the signals present in the quadrature channel, with cross correlation between the channels to provide adjustment of the quadrature correction signals.

Title: Process of separating tar acids from tar
Inventor: CISLAK FRANCIS EDWARD
IPC: C10C1/18
Filed: 1944-07-19
Abstract: Tar acids are separated from coal tar by mixing it with an aqueous caustic alkali solution at a temperature above 100 DEG  C., but preferably below 300 DEG  C., e.g. 125-175 DEG  C., and at a pressure above the vapour pressure of the mixture to separate into two layers while maintaining the said temperature and pressure, and withdrawing at least one layer separately, the separated layers being cooled and the pressure simultaneously or subsequently reduced to atmospheric pressure.  In a continuous method of operating, the coal tar and an aqueous caustic soda solution, e.g. of about 3-6 per cent strength, and preferably in amount in excess of that required to react with all the tar acids present in the tar, are pumped through heaters into the top and bottom respectively of an extraction column in which the required temperature is maintained by, for example, a heating jacket, and the required pressure by suitable means, e.g. by the pumps.  The carbolate solution and the extracted tar are removed from the top and bottom respectively of the column and passed through coolers and then through pressure reducing valves into receivers.  The process is also applicable to batch operation, the tar and caustic soda being introduced into the extraction vessel, which is then closed and the contents heated to the required temperature, thoroughly mixed, allowed to separate, cooled and the pressure released.  The carbolate solution is obtained substantially free from tar, and the tar acids are recovered therefrom in known manner.  The tar layer is for most purposes sufficiently free from alkali, but may, if desired, be further purified by agitating with 0.15-0.3 parts by volume of water at 80-90 DEG  C. and allowing the mixture to separate into two layers at the same temperature.
