Title: A process for steam reforming of hydrocarbons
Inventor: OKADA OSAMU
IPC: C10G25/00
Filed: 1990-05-14
Abstract: A novel process for desulfurizing and steam reforming sulfur-containing hydrocarbons is disclosed. The process comprises the steps of (a) desulfurizing the sulfur-containing hydrocarbon to a sulfur content of 5 ppb or less by use of a desulfurization agent, (b) reforming the desulfurized hydrocarbon at low temperature in an adiabatic reactor by use of steam, and (c) reforming the resultant gas reformed in the course of step (b) at high temperature in an external-heating reformer furnace.

Title: Process for manufacturing granular substances using vaporous reactant, and for cleaning impure acid
Inventor: READ JOHN C
IPC: C01D5/02
Filed: 1990-05-17
Abstract: Abstract of the Disclosure PROCESS FOR MANUFACTURING GRANULAR SUBSTANCES USING VAPOROUS REACTANT, AND FOR CLEANING IMPURE ACID     Potassium Chloride is introduced cold into the reactor chamber, which already contains potassium sulphate particles and sulphuric acid vapour at 460-590 degC.  The acid vapour is forced under pressure through a reactor grid, whereby the particles are blown around within the reactor chamber. Under these conditions, the chloride first converts to the liquid bisulphate phase, which collects on the (solid) sulphate particles.  As the liquid bisulphate heats up, in the presence of the acid vapour, it converts to the sulphate.  The K2SO4 produced thereby is already in the granular form as required for use as a fertilizer.  The invention also allows grease-laden sulphuric acid to be used.  The acid is sprayed onto a fluidised bed, air passing through the bed being hot enough to ignite the hydrocarbons. The heat also vapourizos the acid, and the cleaned acid vapour passes directly to, and though, the reactor grid.

IPC: G06F3/038
Filed: 1990-05-24
Abstract: Abstract of the Invention An apparatus and method for optical encoding is disclosed.  An electrical input means is provided for providing a pulsed electrical input signal.  A light source means is connected to the pulsed electrical input means for utilizing the pulsed electrical input signal to produce pulses of light.  Light collecting and electrical conducting means is provided and synchronized with the light source means.  The light collecting and electrical conducting means is positioned in relation to the light source means for receiving and being responsive to light produced by the pulsed light source means.  An electrical output signal is produced, indicating such a response.  Positionable light interrupting means is provided for opening and closing the optical path of light being transmitted from the light source means to the light collecting and electrical conducting means.  The opening and closing affects the electrical output signal, the resulting pulsed electrical output signal for use in encoding.  The apparatus results in minimized power consumption as a result of the pulsed synchronization of the light source means and the light collecting and electrical conducting means.  The present invention is particularly adaptable for use with cursor control devices for computer controlled display systems.     LNG/mg/04860.P158 4/28/89

Title: Fluid sampling pump
Inventor: ALLEN PAUL V
IPC: G01N1/14
Filed: 1990-07-24
Abstract: A sampling pump is provided suitable for pumping a discrete quantity of either a liquid or a gas per pump stroke from a flow line to a sample vessel. An operator unit drives a piston within the pump bore, and controls the stroke of the piston and thus the quantity of fluid pumped per stroke. A balanced check valve mechanism controls flow from the pump bore to the pump outlet port, and is provided within and carried by the piston. Line pressure acts on the operator end of the piston to assist the operator in driving the piston during its power stroke. A manifold may be secured to the pump body, and has a flow path therein which is in communication with the inlet port to, the pump bore.      The pump may also be used for injection purposes to introduce a selected quantity of fluid to a high pressure line.
Patent CA-2022724-A1 (CA)
IPC: G01D18/00
Filed: 1990-08-03
Abstract: A totalizer apparatus, for use with belt scales and other flow rate measuring devices producing output signals subject to zero drift, maintains an auxiliary totalizer register during zeroing operations so that should zero flow conditions be interrupted during such an operation, a correct total can still be maintained. This enables autozeroing operations to be implemented, for which purpose a further auxiliary totalizer is used to test for an extended absence of flow before permitting initiation of an autozeroing operation. If a zeroing operation results in an apparently excessive zero correction, it is rejected and assumed that flow has restarted during the operation; the first auxiliary totalizer register is used to update a primary register.

Filed: 1990-09-13
Abstract: A phase lock loop for a digital input signal has a phase detector, a loop filter, a digital voltage controlled oscillator (VCO), an initial phase difference calculator, a center frequency difference calculator and an input buffer memory.  In an initial training mode prepared in the PLL operation, an optimum initial phase and an optimum center frequency of the VCO to complete a lock-in state is searched for the input signal stored in the buffer memory.  By estimating the initial phase difference and the center frequency different between the input signal and the VCO output with repetitive kick-offs in calculators, optimum values mentioned above are obtained.  In a normal operation mode as a second mode in which the PLL operates normally as a conventional PLL, a phase lock operation between the VCO output as the reference signal and the input signal in the buffer memory is carried out after the PLL is kicked off with the optimum initial phase and the optimum center frequency determined in the initial training mode.

Inventor: JAMET DANIEL
IPC: H01R13/658
Filed: 1990-11-23
Abstract: A metal housing for an electrical connector such as a standardized HE12 connector comprises two half-housings enclosing a connector plug adapted to be inserted into a socket. Each half-housing comprises a half-hinge and an orifice having a contour which is open when the two half-housings are open to enable insertion of cables and which is closed when the two half-housings are closed. Fork-shape projections in each half-housing constitute two insulation-displacement contacts for establishing an electrical connection between the half-housing and the screening braid of each cable and to prevent the cable being pulled out. Tangs in each half-housing are inserted in insulation displacement contacts when the two half-housings are closed to constitute electrical screens preventing electromagnetic interference between nearby contacts. A captive screw constitutes both a rotation spindle for the hinge and means for fixing the housing to a nut fixed to the chassis. The housing protects the connector against electromagnetic interference.
