Title: Thermal reactor
IPC: F01N3/26
Filed: 1973-09-21
Abstract: 1424765 Consuming noxious vapours; combustion chambers GKN SANKEY Ltd 19 March 1974 [27 March 1973 21 Sept 1973] 14596/73 and 44361/73 Heading F4B In an afterburner for an internal combustion engine comprising a tubular lining located in a tubular casing having their axes parallel, aligned inlets through the casing and lining and aligned outlets in the casing and lining, two baffles are arranged within the lining to form three passages between the inlets and outlets, at least one of the baffles being of channel section. Each inlet or outlet tube is secured to a collar 17, 19, Fig. 2 which is secured to the outer casing and to the engine and exhaust pipe respectively. The inlet and outlet tubes fit loosely in openings in the lining, and two flanges secured together lie on either side of the lining and are a push fit in the inlet or outlet tube to form a seal. A channel shaped baffle 34, shorter than the lining, faces the outlet and supports a second shallow channel section baffle 33 facing the inlets, to form a first passage 42, a two-part second passage 43 connected to the first passage through holes 41 in the second baffle and round the ends of the first baffle to the third passage 44. The baffles may be spaced apart (Figs. 3 and 4) the second baffle may be flat (Fig. 6) or the inlets may open into the second baffle 85, Fig. 5, the gases flowing through holes 90 in the walls of the second baffle and round the ends of the first baffle 82 to the outlet. The gases may be delivered into the interior of the first channel shaped baffle 108, Fig. 7, the second baffle 109 dividing the interior of the baffle into two passages 110, 112, gases flowing through holes in the upper part of the first baffle to an outer passage 111 and round the ends of the cutaway lower part of the channel shaped baffle to the outlet 106. The outer casing is formed of half cylindrical shells, welded together at overlapping flanges 14, Fig. 1, and strong enough to withstand mechanical stresses, while the lining, which is separated from the casing by air or other heat insulating material is formed of heat resistant material only strong enough to stand the thermal stresses. It is formed of two open ended sections welded together, with closures 28 welded to each end. The lining is supported within the casing by bosses 30 at each end engaging annular flanges 31 secured to the ends of the casing, so that the lining may move to allow for differential thermal expansion. The seals at the entry point of the inlet and outlet tubes do not restrict this movement.

It is bacteriostatic to gram positive and gram negative bacteria, and inhibits the growth of fungi, algae and human epidermoid carcinoma cells in tissue culture. The strain of micro-organism used is Trichoderma viride NRRL 3153.  Culture conditions are preferably 25 DEG  to 30 DEG  C., at pH 6 to 8, the vegetative form of the organism being inoculated into a nutrient medium containing assimilable nitrogen and carbon sources, such as casein digest, meat and bone scraps, milk solids, peptone liquors or distiller's solubles for a nitrogen source, and sugar, starch, dextrin or glycerol to supply carbon.  After culture, preferably submerged culture, the antibiotic may be obtained by solvent extraction, with, e.g. ethyl acetate, followed by water extraction of the solvent solution at neutral pH.  The aqueous extract may be freeze dried, or further purified by use of ion exchange procedures, or by adsorbing on such agents as silicic acid, decolorizing charcoal or decolorizing resins, followed by elution with solvent.  It may be crystallized from methylene chloride by addition of hexane.  Dermadin forms salts with metals, such as alkali metals, and organic bases including physiologically active bases (see Division A5).

Filed: 1969-09-17
Abstract: 1284298 Data transmission HONEYWELL Inc 17 Sept 1969 [28 Oct 1968] 45849/69 Heading G4A Digital data transfer between a memory 16 and peripheral units 19 in separate sectors 1-3 is regulated by dividing the time available in at least one sector into time slots and selectively allocating the time slots to the peripheral units collectively and/or individually in relation to their data transfer rates. This patent has features in common with Specification 1,107,661. The apparatus.-A multiprogrammed system comprises a word organized processor 10, a character organized processor 12 operating in a variable length mode, an 1/0 controller 14, and a plurality of memory modules in memory 16 having some protected areas, all controlled by a master programme for parallel data transfer. Processor 10 has a multiprogramming capability and includes sequence counters, index registers, interrupt registers and masking registers. The 1/0 controller 14 (Fig. 2, not shown) sends data between memory 16 and peripheral units 19 in response to request from processors 10, 12. Upon receiving such a request, the controller 14 assigns a read/write circuit therein to interconnect the requested peripheral unit with memory 16. Each circuit includes a storage register identifying the currently addressed memory location and the other stores a starting address where the data to be transfered is stored. The peripheral units are divided into sectors 1-3, each sector having different peripheral control units CUl-CUN. Each sector has a memory slot assignment table in the 1/0 controller 14 which stores control information relating to the processing of instructions involving peripheral devices in the sector. It functions as a memory cycle distributer whose cycling period defines a number of time slot intervals, e.g. six in Fig. 2 and 3 (not shown), each having two control words. Also provided is time slot activity storage with six elements for each sector and means for checking the availability of time slots in a sector, updating and clearing time slot data. Operation.-The assignment of time slot intervals to a peripheral unit involves determining the availability of a read/write circuit, searching the time slot activity table to see if sufficient time slot intervals are available in that sector to accommodate the data transfer rate of the peripheral unit, and assigning the time slot intervals.
