Abstract: Abstract of the Disclosure Steam active reforming catalyst is described which in addition to converting isoparaffins to isoolefins also isomerizes 1-olefins at least in part to internal olefins.  In a combined steam active reforming and ether forming operation a 1-olefin containing stream can be recycled to the steam active reforming zone whereby this 1-olefin is converted to materials which in a separation step downstream from the ether forming reaction can be readily separated from the isoparaffin, the isolefin and the 1-olefin which are recycled to the steam active reforming zone.  The steam active reforming catalyst thus has both the function of a reforming (dehydrogenation) catalyst and that of an isomerization catalyst for disposing of the 1-olefin byproduct and preventing its buildup in the operation.

Granted: 1994-10-11
Abstract: ABSTRACT OF THE DISCLOSURE   A process for producing a crystal comprises the step of applying crystal forming treatment on a light-transmissive substrate having a non-nucleation surface (SNDS) of a small nucleation density and a nucleation surface (SNDL) of a nucleation density (NDL) greater than the nucleation density (NDS) of said non-nucleation surface (SNDS) and formed of  an amorphous material (ML) different from the material (MS) forming the non-nucleation surface (SNDS) at a small area sufficient to effect crystal growth from only a single nucleus to form a single crystal nucleus on the nucleation surface (SNDL), thereby growing a single crystal from the single nucleus, and the step of reducing the crystal defects of the crystal in the vicinity of the interface with the substrate by irradiation of light from the side of the substrate.

Abstract: For the preparation of crystalline sodium silicates hav-ing a sheet structure and an SiO2/Na2O molar ratio of 1.9 : 1 to 3.5 : 1 from waterglass solutions having a solids content of 20 to 65% by weight, the waterglass solutions are first treated in a spray-drying zone.  This gives a pulverulent amorphous sodium silicate having a maximum ignition loss of 20% by weight, while the waste gas leaving the spray-drying zone is at a temperature of at least 140°C.  Thereafter, the spray-dried sodium silicate is heated in an ignition zone containing an agitated solid bed at temperatures of 500 to 800°C for 1 to 60 minutes in the presence of at least 10% by weight of recycled material. This recycled material was obtained by mechanical comminution of crystalline sodium silicate discharged from the ignition zone.

Title: Process for hydrotreating catalytic cracking feedstocks
Inventor: DERR WALTER R JR
IPC: C10G69/04
Filed: 1988-07-15
Granted: 1992-06-02
Abstract: PROCESS FOR HYDROTREATING CATALYTIC CRACKING FEEDSTOCKS                            ABSTRACT          Catalytic cracking of hydrocarbon feedstocks is improved by hydrotreating the cracking feed under conditions of relatively low temperature, typically below 390°C for start-of-cycle, and high pressure, typically above 10,000 kPa, preferably above 12,000 kPa. The use of these conditions favors aromatics saturation to produce a cracking feed of improved crackability so that higher conversion is achieved in the cracking step at constant cracking conditions with production of naphtha of good octane quality.  At the same time, desulfurization is achieved to maintain cracker SOx  emissions at required levels; the advantages of high pressure operation are more notable at high denitrogenation severities while still achieving a low catalyst aging rate.

Abstract: ABSTRACT OF THE DISCLOSURE      A plastics clip for performing sexual sterilization comprises two jaws each having a lining of silicone rubber, hinged to move from an open position to a closed position, in which a Fallopian tube is occluded.  A catch mechanism biasses the jaws apart when the clip is open, by means of pressure from a resilient finger on a cam profile attached to the upper jaw.  The finger and underside of the cam profile engage when the jaws reach their closed position, and lock the jaws closed.  During closure, a resilient tongue formed on the upper jaw and a projection forming a hook on the lower jaw prevent the tube from escaping.  Due to the biassing, the clip will spring back open during application if not sufficiently closed to engage the catch mechanism.  In conjunction with the biassing, two moulded recesses and the shaping of the clip in a region adjacent the hinge end enable the clip to be located firmly in an applicator before closure.  When closed, the jaw members define therebetween a first region lying adjacent the hinge and receiving a tube to be occluded, and a second region at the free ends of the jaws remote from the hinge.  The second region has a cross-section of a size to prevent a Fallopian tube being withdrawn therethrough whilst permitting the mesosalpinx of the tube to pass relatively freely.

Title: Refuse container with two-position lid
Inventor: GLOMSKI NORMAN J
IPC: E05D3/02

Granted: 1994-04-12
Abstract: Abstract of the Disclosure A refuse container has a two-position lid. The two positions are achieved by means of a J-shaped slot in a lid hinge.  The slot receives a horizontal shaft supported in the container body. In the first open position, gravity acts on the lid such that the shaft is at one end of the slot, and the lid hinge abuts a pad on the container body for maintaining the lid at an angle of approximately 105° from a horizontal closed position.  To pivot the lid to the second open position, the lid is lifted such that the slot slides over the shaft until the hinge clears the container body pad, at which point the lid is pivotable to approximately 270° with respect to the horizontal closed position.

Abstract: ABSTRACT OF THE DISCLOSURE In coded speech communication, discrete speech samples are analyzed to generate a first signal indicating the fine pitch structure of the speech samples and a second signal indicating their spectral characteristic.     The amplitudes and locations of main excitation pulses are determined from the fine pitch structure and spectral characteristic and a third signal indicating the determined pulse amplitudes and locations is generated.     The difference between the speech samples and the main excitation pulses is detected and used in auxiliary excitation pulse calculation to determine gain and index values of auxiliary excitation pulses by retrieving stored auxiliary excitation pulses from a code book so that the retrieved auxiliary excitation pulses approximate the difference. The first, second and third coded signals and the gain and index values are transmitted through a communication channel to a distant end where a replica of the main excitation pulses is recovered from the received first and third signals and a replica of the auxiliary excitation pulses is recovered from a code book in response to the received fourth signal. These replicas are modified with the second signal to recover a replica of the original speech samples.

Abstract: The invention enables extremely quick and reliable recovery of the synchronization of a communication signal transmitted in a half-duplex link. Such a communication signal comprises first time intervals including useful data, and second time intervals devoid of useful data and in a given logic state. At the beginning of each of the first time intervals is included a digital synchronization pattern which is then considered as associated with the second time intervals to form synchronization words of great length. The synchronization of the communication signal is recovered by detecting the synchronization words of great length in the communication signal.
