Title: Method for accelerating the hardening of adhesives or sealing agents which harden under exclusion of oxygen
IPC: C09J4/00
Filed: 1967-04-14
Abstract: A method of accelerating the hardening of anaerobic adhesives or sealing compounds based on a mixture of an acrylic or methacrylic ester, an organic peroxide and an amine, comprises pretreating surfaces, which are to be joined together with said adhesive or sealing compound, by depositing thereon a coating of an organic isocyanate. The (meth)acrylic component may be a partial or full ester of, for example, ethylene, diethylene, triethylene, tetraethylene, propylene, butylene or neopentyl glycol or of trimethylol-propane, or it may be an ester of a monohydric alcohol such as cyclohexanol, tetrahydrofurfuryl alcohol or 1,3-dioxa - 2,2 - dimethyl - 4 - methylolcyclopentane. Suitable peroxides include cumene hydroperoxide, t-butyl hydroperoxide, diisopropyl benzene hydroperoxide, t-butyl perbenzoate and 2,2 - bis - (t - butylperoxy) - butane, and amines specified are triethylamine, tributylamine, N,N,N1,N1 - tetramethyl - 1,4 - butane - diamine, N,N - diethylcyclohexylamine, N,N - dimethylaniline, N,N - dimethyl - p - toluidine, N - methylpiperidine, N-methylmorpholine and 1,4-diaza - bicyclo - [2,2,2] - octane. The isocyanate accelerator may be an aliphatic or aromatic mono- or poly-isocyanate, or a higher molecular weight product as obtained, for example, from aromatic uret dions. The isocyanate is generally applied to the surface to be treated as a solution in an inert organic solvent, e.g. a halogenated hydrocarbon. The method is suitable for bonding together materials such as zinc, iron, anodized aluminium, highly alloyed steels, cadmium, glass or plastics, e.g. polymethacrylates and polyvinyl chloride. In some examples the ester monomer was stabilized with hydroquinone and, in one case, the monomer (2-hydroxyethyl methacrylate) is admixed with polymethyl methacrylate.

Title: Full arc-partial arc transfer system for electrohydraulic turbine control
IPC: F01D17/18
Filed: 1968-01-11
Abstract: A steam turbine control system has a plurality of valves 1...4, Fig.1, each supplying steam to a circumferentially spaced nozzle arc inside the turbine casing 5, an electro-hydraulic amplifier 9 to position each valve in response to a common electrical valve positioning signal first means 31... 34, Fig. 3, for varying the respective gains of the amplifiers, second means 39...42 for supplying biasing signals to the amplifiers, and means 45 to simultaneously vary the gains of the first means and relative biases of the second means to transfer the turbine from partial to full arc operation. Each valve 12, Fig. 2, is adjusted by a piston 13 controlled by a valve 14 and a pivoted jet 15 fed with signal and bias voltages through amplifiers 19 and 20. A linear variable differential transformer 24 provides a signal for a feedback loop including a demodulator 25 and a function generator 26 which may be used to compensate for a non- linear variation between steam flow and valve position. Each valve opens when the signal voltage is sufficient to overcome the bias applied to its amplifier and the biases are so adjusted by potentiometers 35...38 that the valves are opened in sequence by an increasing signal voltage during partial arc operation. During full arc operation, however, a common earthed bias signal is applied to valves 2 to 4 as shown in Fig. 3 and the gain of the amplifiers is simultaneously reduced by a factor equal to the reciprocal of the number of valves. Valve 1 has a screwdriver adjustment 44 to provide zero bias during both full and partial arc operation.

Patent ES-371265-A1 (ES)
Title: Domain propagation arrangement
IPC: G11C19/08
Filed: 1969-08-28
Abstract: In a magnetic device comprising a layer of magnetic material having associated therewith an overlay of magnetic material to define a single wall domain producing region and a domain propagation channel the arrangement is such that when an appropriate magnetic field rotating in the plane of the layer is applied a single wall domain is produced at the input of the channel and propagated therealong. In the arrangement of Fig. 1 the single wall domain producing region and propagation channel of sheet 11 are defined by a disc 15 and bar and T-shaped overlays 13, 14 of permalloy. When a rotating magnetic field H produced by orthogonal sets of coils B, B1 is applied a permanent domain D provided in the layer 11 moves about the periphery of the disc as shown in Figs. 2-8, positive poles induced in the overlay by the magnetic field attracting the domain. The domain is stretched until as shown at Fig. 7 it is about to divide into two, then Fig. 8 the domain divides one following the bar and T and the other D1 moving about the disc again. The rotating field also results in propagation of the domains along the channel to the output position coupled by conductors 19, 21, a pulse on conductor 19 resulting in a domain coupled thereto collapsing the domain and inducing a signal in conductor 21, the presence or absence of a domain indicating a "1" or "0". Since the field required for propagation is less than that required to divide the domain D the rotating magnetic field has its strength varied so that it is only increased when a domain is to be introduced and then only for the last quarter of the cycle. The overlays for a plurality of propagation channels may be provided on one side of the magnetic layer 11 and the respective input overlays each of different geometry e.g. rectangular, disc or cross-shaped on the other side, Fig. 9 (not shown). The amplitude of the rotating field thus determines the channel into which a domain is introduced. By providing a generalized pattern of overlays domains may be introduced and propagated in X and Y directions. Domains may be introduced into more than one channel from a given input overlay by increasing the amplitude of the rotating field during different quarter cycles, Figs. 10 to 13 (not shown). In a further arrangement three parallel bars of permalloy are used, Figs. 14, 15 (not shown) two of the bars being of low coercive force and the middle one of high coercive force.

Title: Continuous casting machine
IPC: B22D11/14
Filed: 1972-07-13
Abstract: A continuous casting machine having an arcuate channel into which molten metal is poured. The metal is guided through the channel and then straightened as it exits from the bottom of the channel and onto a horizontal conveyor. Two pinion-driven racks are provided at the sides of the arcuate channel, each rack having a head for gripping one of two arms of a starting plug which is inserted at the top of the channel while the flow-through mold at the top of the channel is moved out of the way. The racks are then driven so that the starting plug leads the casting down the channel, the rack heads being separated from the starting plug automatically at the bottom of the channel so that the racks can be returned immediately to the top of the channel while the casting continues. In this manner, as soon as the tail end of a casting exits the mold, the mold may be moved out of the way, a new plug may be inserted at the top of the channel with its arms gripped by the two rack heads, and a new casting may begin immediately.
