Title: Paraffin dehydrogenation to olefins - using catalyst contg. gallium, indium and/or thallium, added to platinum and alkali metal on alumina
IPC: C07C/
Filed: 1976-06-21
Granted: 1985-02-11
Abstract: Dehydrogenation of 5-20 C paraffin hydrocarbons to the corresp. olefins takes place by contacting the paraffins with a catalyst contg. an active Al2O3 support, 0.2-1wt. % applied Pt, followed by 0.2-2wt. % applied alkali metal, and, in addn., 0.2-1wt. % Ga, In and/or Tl. Contact takes place in H2, at 440-550 degrees C under press. from 1 atmos. to 5 atmos. over-press. Mol. ratio H2/paraffins is 1:1 to 15:1. Vol. velocity of charged initial hydrocarbons is 1-50 hr.-1, w.r.t. liquid raw material. Olefins obtd. are useful raw materials for synthetic of rubber, detergents and surfactants. The added Ga, In and/or Tl act as promoters. Yield of olefins is increased e.g. by 10% at higher press. and 1.5-2x at atmos. press. Process selectivity to olefins reaches 93% at conversion 16-16.5%.

Abstract: A maintenance interface is provided for interfacing a service processor and a central processing unit operating asynchronously to each other. The maintenance interface includes circuitry for synchronizing the service processor to the central processing unit and decode circuitry for interpreting commands from the service processor. The maintenance interface also includes circuitry responsive to control signals from the central processing unit such that the maintenance interface establishes communication between the service processor and the central processing unit. The central processing unit includes a microprocessor for interpreting data sent between the service processor and the central processing unit. The maintenance interface is responsive to control signals from the central processing unit to resolve communication contention between the central processing unit and the service processor. The maintenance interface further facilitates the use of the LSSD testing procedure by degating central processing unit interfaces as required for this testing approach.

Title: Coking of waste kraft pulping liquors at lowered pH - by blowing liquors with sulphur dioxide prior to coking
IPC: D21C/
Filed: 1974-12-31
Granted: 1979-01-30
Abstract: Alkaline kraft pulping liquors are treated by (a) flowing the liquors to an adsorbing zone and adding SO2 to lower the pH to 7 (b) coking under autogenous pressure in a coking zone to form coke, H2S-contg. gas and aq. effluent (c) burning the coke to produce SO2 for recycle to step (a), and (d) adding lime and H2S to the effluent in a second adsorbing zone to form new kraft cooking liquor. Reducing the pH to 7 in step (a) lowers coking chemical O2 demand (COD) and shortens coking residence time.

Title: Plastic containers prodn.

Granted: 1990-01-05
Abstract: The system generates a digital pixel image in a framestore memory (20) by expanding run-length encoded data stored in a command memory (22). Each pixel has a variable characteristic such as its colour, or its depth in a 3-D image. The value of the characteristic for each written pixel is determined from the run-length encoded characteristic. The value of the characteristic for each pixel in the run is determined from a reference parameter which determines the initial value of the characteristic, and a difference parameter which represents the change in the value along the length of the run. The coordinates of the pixel runs may be determined from the coordinates of a preceding run. The initial location and run length for each run are determined relative to the preceding run by delta parameters associated with the current run. The system generates linear colour blends and automatically depth-clips images being written into the framestore (20).

Abstract: Hot pressed Si3N4 is prepd. by (a) forming a powder mixt. of Si and reactive O-carrying agents including dry or jet milling to an absolute particle size distribution having no particle larger than 16 microns; (b) compacting to form a preform density 1.1-1.4 g/cm3; (c) heating in a nitriding atmos. without press. to fully react ingredients with the atmos., forming an Si3N4 body; and (d) hot pressing to produce an Si3N4 object of desired dimensions and density, useful as a cutting tool. The mixt. pref. has a max. particle size 3-4.5 microns. The mixt. may also contain 2-25% Si3N4 composite (of the same compsn. of the final object) to increase packing efficiency. The resulting object pref. has a modulus of rupture 150-190 ksi and a hardness (45-N) at least 92. Flaws causing strength redn. are reduced, providing a strength much higher than the conventional 100 ksi. and a hardness above conventional 90-92.

Also, an innermost cathode tube (56) can have a plurality of apertures (58) as passageways for the solution. A DC voltage is applied, in one direction or in sequential fields of different directions, across the plurality of metal rods and tubes, thereby effectively removing both suspended materials and dissolved solids from the aqueous solution to be treated. The power required form the DC voltage source (35) can be decreased by treating specified tubes or rods.

Title: Method for reducing noise from suction rolls and noise suppressor which implements this method
Inventor: BERNSTROM RICHARD
IPC: D21F3/10
Filed: 1978-11-09
Abstract: This invention consists of a method for reducing noise from suction rolls, especially the pure tones that are generated in the sheath's drill hole. The air columns in the drill holes are set in motion when the holes pass the suction box C and tones of different strength are generated as a result of the movement depending on how the volume between the sheath and the suction box C is designed. The basic idea behind the invention is that this space shall be designed so that anti-resonance for the tones in the drill holes is generated which results in a reduction in noise generation. The noise suppressor thus consists of a plate B, non- perforated or perforated, placed inside the suction roll and at a suitable distance from the sheath or the paper path E. <IMAGE>

Abstract: The invention concerns an arrangement for heat treatment of food products, which arrangement comprises a chamber 1, which is divided by a partition wall 5 into a continuous baking zone 6 and a drying zone 7, and a process chain conveyor 2, which has an upper running part 3 and a lower running part 4, and which is arranged to carry a large number of cassettes 27 to accommodate open cans 16 with a food product being processed, which cassettes can be opened and closed, wherein the smaller chain wheel 18 of the conveyor 2 has a tooth division which is equal to three link divisions of the chains 17. Each cassette 27 has two support ribs 28 and 29, which are arranged at the output side of the running parts 3 and 4 of the conveyor 2. A lengthwise edge for each support rib 28 and 29 in the same cassette 27 is outwardly bent in the direction of the other similar support rib. Each support rib 28 and 29 is joined by its ends to a pair of pins 22 on the different chains 17 of the conveyor 2 by means of a similar pair of pins and provided with side plates 30 and 31 that are fastened to its end surfaces.

Title: Process for opening up mineral-bearing deposit and subsequent mining thereof
Inventor: HOBERSTORFER GUSTAV
IPC: E21F15/00
Filed: 1980-10-24
Abstract: The invention relates to a new, general-purpose process for opening up ore deposits for prospecting purposes and subsequent mining, in which necessary ramp systems, drifts or tunnels (development works) which were previously placed in waste rock are now entirely or almost entirely placed in the ore. Since the deposit can be pre-developed, i.e. since within the deposit a variety of ore grades, such as ore types and/or contents, are exposed and made directly and continuously accessible in this way, the process further allows the subsequent mining in each given case to be adapted and steered in the desired direction, whereby the business cycle can be optimally matched to the presently prevailing economic situation. The process should therefore not only be regarded as a new process which, firstly, during the prospecting stage of a deposit, reduces the capital risk factor and, secondly, during the subsequent mining, maximizes the returns, but also as a totally new mining strategy, since the process creates ore, i.e. economically minable deposits of mineralizations which were not previously worth mining. <IMAGE>
