Abstract: 1533704 Recovery of Al BRITISH ALUMINIUM CO Ltd 14 Nov 1975 [18 Nov 1974 6 Oct 1975] 49778/74 and 40791/75 Heading C7D  Aluminium (including Al-base alloys) is recovered from aluminous material, comprising furnace skim, dross, metal residues or finely-divided scrap, by feeding it into a liquid salt flux layer floating on a body of liquid A1 and agitating to allow the A1 to pass into the body. The body of liquid Al may be held in a side-well 22 of a reverberatory melting furnace 21 such that the body of A1 23 is in communication with the molten Al 24 by channels 25 in the baffle wall 26. The skim 28 is raked on to the flux layer 27. The flux is based on the chlorides of the alkali and alkaline earth metals (inc Mg), and may also contain one or more corresponding fluorides. Suitable fluxes contain NaCl and KCl either in equal weight proportions or in eutectic proportions and may include 0-5% Caf 2 , 0-25% NaF and 0-20% MgCl 2 . In other embodiments, the treatment may be carried out in a heated crucible (Fig. I not shown), in a mobile refractorylined box (Fig. 5, not shown), in a crucible held partially submerged in an Al melt and being in communication with the melt by means of holes in the bottom and side-wall, the agitation being effected by a tangential jet of liquid Al into the crucible (Figs. 6-9, not shown) and in a refractory ring movable over the surface of an Al melt relative to an Al jet (Figs. 10, 11, not shown).

Abstract: 1354059 Pile drivers DELMAG-VERWALTUNGS GmbH [trading as DELMAG-MASCHINENFABRIK REINHOLD DORNFELD] 2 Nov 1972 [6 Nov 1971] 50549/72 Heading B3H A pile driver of the combustion-type, e.g. a diesel hammer, has a piston 32 reciprocatable in a cylinder 30 to impact against an anvil 26 to atomize fuel injected on to the flat surface of the anvil from a nozzle 42 in the cylinder wall which also has at least one air inlet and gas exhaust port 24 on the opposite side of the cylinder to the nozzle. In a preferred arrangement there are two ports 24 arranged symmetrically about the diametric plane of the cylinder including the nozzle, Fig. 3 (not shown). The fuel is injected by a pump actuated by a lever 40 as the piston descends. The burnt gas from the previous stroke is forced out through the port 24 and the gas flow does not substantially deflect the fuel jet 44 and thus wetting of the cylinder walls is prevented.

Title: Apparatus for determining the time of attainment of a reference value of an electrical signal
IPC: G06G7/30
Filed: 1973-11-02
Abstract: 1433766 Pulse detector circuits; echosounders FRIED KRUPP GmbH 2 Nov 1973 [4 Nov 1972] 51036/73 Headings H3P and H4D Apparatus for indicating the attainment of a given value by a wave having a unique slope at the value comprises means for attenuating the wave by #Y, means for delaying the wave by #t and a comparator for detecting at least equality of the output of the means. The invention is applied to determining a point in the envelope of the received signal in an echosounder whereby the beginning of the received signal, where the level is low and obscured by noise, can be estimated. The burst of test oscillations is applied to a timing device 11 to initiate timing and also to the path 10 under test. The output of the path, having an exponential envelope, is picked up in a receiver 17, attenuated at 19 by #Y to produce i 4  and its peak value is detected at 21 to produce a wave S21 (Fig. 5c) which is applied to one input of the comparator 24. The other input 22 receives the output of the receiver via a circuit 18 producing a delay #t equal to one cycle (waveform 5b) and a peak detector 20 (waveform S20). The comparator produces a pulse S24 at near equality of the peak values and thus stops the time measure. To avoid inaccuracy due to the small slope at the peak, the timing of the pulse may be delayed until the next zero crossing is detected by circuit 26. The difference in time between the detected point and the beginning of the received pulse burst is a known value and is allowed for in the time measuring device. A further output from the comparator acts via a circuit 29 to block the receiver, such blocking being removed by the onset of the next pulse from generator 12. False operation due to the initial equality of the peak detector outputs before the burst arrives may be removed if a comparator operates on a given difference.

Abstract: 1400399 Flexible hoses BTR INDUSTRIES Ltd 31 Oct 1972 [3 Nov 1971] 51074/71 Heading F2P In a method of making a flexible tube or hose 17, a strip, or strips, 12, 13 of elastomeric or polymeric material, having embedded therein aligned lengths of filamentary material 14, are helically wound over an inner tubular layer 18 also made of elastomeric or polymeric material. In one embodiment, as shown, the inner layer comprises a strip 18, which also has aligned filaments embedded therein, laid along a mandrel 11 and transversely curved therearound to form a seamed tube. Further similar strips 12, 13 are then wound helically in opposite hand directions at an angle of from 40 to 70 degees and preferably at 54 degrees 44 minutes. Another strip 15 of nylon-coated scrim such as woven, non-woven or knitted textile is wound over the strips 12, 13 followed by a continuous wire reinforcement 16. Several such wire layers may be wound on to the tube, each separated by a layer such as 15. A final protective coating of polymeric material is applied around the outermost wire reinforcement. In an alternative arrangement, the inner tubular layer is extruded from elastomeric or polymeric material having filaments embedded therein which tend to align during extrusion. In a further embodiment, the inner tube consists of one of the helically wound layers, 12 (Fig. 1, not shown). The filaments 14 may comprise chopped strands or rovings of nylon, rayon, cotton, polypropylene, " Terylene " (Registered Trade Mark) or metallic wire. The elastomeric or polymeric strips are wound in an uncured, or partly cured state, curing being effected on the mandrel when the tube is otheriwise complete. Such elastomeric or polymeric materials which are used are nitrile, polychloroprene or epichlorhydrin rubbers.

Title: Method and apparatus for exchanging information between a central unit and a peripheral controller in a data-processing installation
IPC: G06F13/42
Filed: 1974-11-28
Abstract: 1478503 Transmitting data COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE CII-HONEYWELL BULL 28 Nov 1974 [30 Nov 1973] 51651/74 Heading G4A In a transmission system between a stored program central processing unit and a peripheral controller, a signal STO (Fig. 11) is transmitted from the central unit together with data, the signal STO resulting in a signal STI from the peripheral controller to the central unit which causes STO to fall off, the peripheral controller then accepting the transmitted data. Similarly to transmit data from the peripheral to the central unit first signal STI is generated signal X 1  (Fig. 7a) becoming 1 so that the output X of store S 1  becomes 1. If the input/output controller is available the output gate A1 drops to zero to enable gate A2 to generate signal STO which in turn turns off signal STI (which enables gate A 1  to disable gate A 2  and so switch off signal STO). Timing signals TMO and TMI indicating that the peripheral and central units respectively have finished transferring data may be similarly generated. The exchange of information is controlled by a group of micro-instructions contained in a store associated with the peripheral controller, a service code accompanying the microinstructions indicating the nature of the exchange. Transfer of data cannot occur before an initializing service code sequence has occurred. This is transmitted to the peripheral controller in response to a signal CPW (Fig. 11) which generates the initializing signal SCI. After initialization the central unit transmits data, if the initialization is for data to be transferred or, if it is for a new channel program, a number of bytes the first corresponding to the number of the channel associated with the program and the remaining bytes corresponding to the channel program.
