Title: Reconditioning method for a non-acidic catalyst used in a high severity process for dehydrogenation of light hydrocarbons
Inventor: COTTRELL PAUL R
IPC: B01J23/96
Filed: 1992-01-28
Abstract: A high severity process for the dehydrogenation of a hydrocarbon selected from the group consisting of propane and butane in the presence of a catalyst comprising platinum and a non-acidic carrier material is substantially improved by periodically reconditioning the resulting coke-deactivated catalyst particles containing platinum by moving the catalyst particles through a combustion zone, a drying zon, a re-dispersion zone and a reduction zone. Dryingof the catalyst particles immediately after the combustion of coke substantiallyimproves the operation of a platinum re-dispersion zone. The lower moisture content in the re-dispersion zone allows the equilibrium reaction between hydrogen chloride and oxygen on the one hand, and water and chlorine on the other hand to be shifted to the production of chlorine. This shift of the equilibrium reaction can be further improved by maintaining an oxygen-enriched environment within the platinum re-dispersion zone. The use of a much lower chloride concentration in the re-dispersion zone reduces the emissions of hydrogen chloride from the regeneration zone.

Title: Interpolative analog/digital converter for band-pass signals
Inventor: DRESSLER HANS-JOACHIM
IPC: H03D1/00
Filed: 1990-12-19
Abstract: (57) Abstract The invention relates to an interpolative analog/digital converter for band-pass signals in which the amplitudes of the scanning values are quantized in 2 consecutive stages. The first stage contains the actual analog/digital interface and the second stage is purely digital. The amplitudes of the scanning values are not quantized, as in other processes, using finely quantizing ele-ments at the analog/digital interface, but by overscanning, shaping of the quantization noise spectrum and digital interpolation. As a result, very coarsely resolving elements (with only 2 quantization stages in the extreme case) can be used at the actual ana-log/digital interface.

Title: Error detection for digital television equipment
Inventor: ELKIND BOB
IPC: H04N19/89
Filed: 1992-09-30
Abstract: Abstract of the Disclosure Error detection for digital television equipment that strips away the vertical and horizontal intervals of a digital video signal so that only the active picture portion of the digital video signal is determined by a digital test signal generated from the digital video signal.  The digital test signal has replaced at a predetermined location in the active picture portion of the digital video signal one or more video data words with data values that represent check word data for the active picture portion.  The check word data may be inserted into the beginning of one of the horizontal lines of the active picture portion of the next field, or may be modified and inserted into the end of the last line of the active picture portion of the same field of the digital video signal.  A receiving instrument processes the output of the digital television instrument under test to generate active picture check word data. The active picture check word data is compared either with the check word data extracted from the predetermined location in the active picture portion of the digital test signal or with a predetermined value to determine whether there were any digital errors in processing of the digital test signal by the digital television equipment.

Patent CA-2089758-A1 (CA)
IPC: G01N21/61
Filed: 1991-11-04
Abstract: Particulate concentration of diesel exhaust is measured by collecting the diesel particulate on a filter (18) while measuring the amount of exhaust passing through the filter (18). The filtered particulate is then heated in an oxygen rich environment (32) to oxidize carbon within the particulate to carbon dioxide. The amount of resulting carbon dioxide is measured in meter (38) to de-rive a corresponding measurement of the amount of filtered particulate. Particulate concentration is calculated by comparing the amount of exhaust passed through the filter. Filtered particulate can be heated incrementally to obtain a measurement of volatile components within the particulate prior to the oxidation of the non-volatile carbon component. The filter (18) employed to collect the particulate is of a high temperature resistant type making it reusable and can be either integral with or inserted into the oxida-tion chamber of the instrument. Oxidation of the particulate inherently concurrently cleans the filter for reuse.

Abstract: PHD 92.020                                       14.01.1993 ABSTRACT: Method of generating X-ray images and device suitable for carrying out the method.     The invention relates to a method of generating X-ray images by means of a photoconductor which is provided on a conductive substrate and whose surface potential can be read by means of probes, and also relates to a device suitable for carrying out the method. In order to avoid image artefacts which could be caused by deviating sensitivities of the probes or by frequency-dependent distortions, after the charging of the photoconductor the substrate potential is varied during a test phase. Test data is generated which correspond to the spatial or temporal variation of the potential on the surface of the photoconductor; from this test data there is formed correction data which is stored in order to correct the image data of a subsequent X-ray exposure.

Abstract: A variable ratio epicyclic drive transmission comprises a drive shaft (10), a driven shaft (11), a sun wheel (12) fixed on the driven shaft (11), a stationary outer ring member co-axial with said shafts, a planet carrier (15) fixed to the drive shaft (10) and three planet wheels (19) swing mounted on said carrier and in engagement with said ring member. The ring member comprises an almost complete, but broken, substantially circular loop of chain (14) engaged by said planet wheels (19) and supported by a contractile iris structure permitting the diameter of the loop to be varied while maintaining its circularity. The preferred iris structure comprises a circular array of guide blocks (27) in which the chain may slide, two circular hoops (25, 26) surrounding the array of guide blocks and pivotal links (28) supporting the blocks from the hoops such that rotation of one hoop relative to the other causes the array of blocks to change diameter. The ring member also comprises joint means (20) comprising a tail guide and escapement devices (Fig. 3) enabling chain to be drawn from or fed into the loop one link at a time. Short bridging racks (47) span the break in the loop at the tail joint means to maintain continuity of engagement of the ring member by the planet wheels as they pass the joint means. The planet wheels (19) are swing mounted on the planet carrier and continuously urged into engagement with the chain loop. The motion of the planet wheels (19) is transferred to the sun wheel (12) by (in respect of each planet wheel) a first transfer gear (53) fixed relative to and coaxial with the planet wheel, a second transfer gear (54) mounted for rotation about the swing mounting axis of the planet wheel in engagement with the first transfer gear (53) and a slave gear (55) fixed relative to and coaxial with said second transfer gear (54) and in engagement with the sun wheel (12).
