Patent EP-0049157-A2 (EP)
Inventor: HIRTLE ALLEN C
IPC: G06F13/22
Filed: 1981-09-29
Abstract: Polling means for polling a plurality of devices with receive and transmit channel numbers. The channel numbers are held in a register 504 and a recirculatory FIFO memory 500, and circulated through the register and memory, the channel number in register 504 polling the devices via line adapter 66. The channel number sequence defines the priorities of the channels, receive channels first then transmit channels. On a device response, the channel number is held in register 504 while the other channel numbers recirculate, so that on the next polling, a responding receive channel has top priority while a responding transmit channel has bottom priority. A counter 514 determines the mode of operation (initialize, scan, etc.) and a flip-flop 524 provides the receive/transmit bit of each channel number.

Abstract: There are described a number of plasmid vectors suitable for the expression of genetic material, at various levels in yeasts. The plasmids each comprise a yeast selective marker, a yeast replication origin and a yeast promoter positioned relative to a unique restriction site in such a way that expression may be obtained of a polypeptide coding sequence inserted at the restriction site. The promoters used are derived from the 5' region of a gene coding for a yeast glycolytic enzyme e.g. phosphoglycerate kinase (PGK), or from the 5' region of the yeast TRP1 gene. In one Example a plasmid contains a promoter derived from both the 3' and 5' regions of the PGK gene. The replication systems used involve the yeast 2µ replication origin or an autonomous replicating sequence (ARS) stabilised with an ARS stabilising sequence (ASS). The replication systems allow for a choice of high or low copy number per cell. The promoter sequences allow for a choice of high or low expression level. A kit including vectors having a combination of these alternative features is described. Yeast expression vectors including a gene for coding for human interferon-a are described.

Abstract: Mineral impact breaking apparatus uses a divided flow with the first part of the flow being accelerated preferably through a rotor and discharged towards an impact breaking surface. The second part of the mineral flow is introduced into the path of the accelerated first part of the flow so that there is impacting between the first and second flows of minerals and with the second flow acting as anvil blocks against which the first flow particles will be impacted and broken. Where the horizontal accelerating rotor is used to accelerate the first part of the mineral flow the kenetic energy of the rapidly rotating air above the rotor is used to direct an air flow back to the infeed of the rotor and minimise dust discharge.

Abstract: Two wound-metallized-polypropylene capacitor sections (10, 26) of cylindrical dimensions are housed in an oval metal can (56). One capacitor section (26) forms a single capacitor of two metal film electrodes (12, 14). One metal film electrode (14) of the other capacitor section (10) is opened or interrupted in the winding. The uninterrupted other film electrode (12) of this other section is terminated at the bottom end (36) while the two interrupted inner and outer winding films (14a, 14b) are separately terminated at the top end (32, 34). The bottoms (30, 36) of both capacitor sections (10, 26) are connected together and to a feed-through terminal (50). Said outer film (14b) is connected via a conductive strap (38) to the top termination (28) of the one section (26) and to a second terminal (52), while the inner film (14a) is connected only to a third terminal (48). In this way, an optimally dense oval package provides two capacitors at the package terminals that may have a ratio of values ranging from 3 to 12, ideally suited for use in air conditioners.

Abstract: 1. A process for regenerating the content of fluxing tanks, which is formed by chlorides of zinc and ammonium in aqueous solution in which steel components are dipped prior to galvanisation, the process comprising, in order to remove the harmful dissolved iron, taking off in a closed circuit the content of the tank which is maintained at a pH-value of between 3 and 6 and adding oxygenated water to the material taken off so as to cause all the iron present to go to the trivalent state and form insoluble sludge of ferric hydroxide oxide which is removed prior to returning the solution to the tank, characterised by taking off a flow at a practically constant flow rate, simultaneously adding to said flow flows of oxygenated water and ammonia which are respectively regulated in such a way that the oxygenated water is substantially in stoichiometric equilibrium with the iron to be oxidised and the pH-value is maintained at between 3,9 and 4,1, allowing the formation of flakes of ferric hydroxide to be concluded in the flow in a practically non-turbulent flow condition, and transferring the flow into a settlement zone where it circulates upwardly in such a way that the hydroxide sludge accumulates at the bottom from which it is discharged, and collecting at the surface the solution of chloride of zinc and ammonium from which iron has been removed, said solution being heated in the settlement zone by the application of heat at the surface at a temperature which is at least equal to that of the solution in the tank.

Abstract: Catalysts are made from supports which are doubly promoted with ceria and an alkali metal oxide by adding these promoters and the catalytic noble metal components in a specified order. The ceria is first applied to the support. It can be applied in a salt form such as cerous nitrate. this impregnated support is then calcined to form a deposit of ceria. Next, solutions bearing the noble metals are applied to the ceria-promoted support and with these solutions the alkali metal component is applied. After subsequent elevated temperature activation, the alkali metal component is converted to an alkali metal oxide and the noble metals are converted into their metallic or oxide form. 
     When lithium is chosen as the alkali metal promoter, it can alternatively be applied to the support along with the initial ceria promoter. After calcining the support to yield the ceria and lithia promoters, the noble metals can then be deposited and subsequently activated at an elevated temperature. Using this process it is possible to have the noble metals deposited on the support so that their penetration depth is less than 300 microns as measured by the SnC1 2  solution staining method to provide an effective three-way catalyst suitable for use in auto emission control.
