Patent ES-8305672-A1 (ES)
Title: Process for the preparation of methyl tert-butyl ether and ethyl tert-butyl ether.
IPC: C07C43/04
Filed: 1982-07-27
Abstract: A process is described for the preparation of methyl tert-butyl ether and ethyl tert-butyl ether by the selective reaction of methanol and ethanol respectively with isobutylene contained in C4-hydrocarbon fractions, in particular those resulting from processes for the thermal or catalytic pyrolysis of suitable petroleum fractions. The reaction is carried out in the liquid phase, under the influence of acid catalysts, at increased temperatures and pressures and with a molar ratio of the alcohol to the isobutylene equal to or approximately equal to the stoichiometric value. To the reaction medium are added inert aliphatic hydrocarbons which are liquid under the operating conditions in order to dilute the medium to a greater extent than the dilution given by the inert hydrocarbons contained in the C4-fraction of the feed. For this purpose, in the most typical embodiment, the exhausted C4-fraction itself is recycled to the reaction medium. By means of this dilution, the thermodynamic equilibrium conditions of the reaction system are favourably influenced, and improved conversions of the isobutylene to the useful reaction product are achieved. Embodiments are disclosed which are particularly suitable for the preparation of methyl tert-butyl ether and ethyl tert-butyl ether.

Title: Allergy screening system and method of making and using same.
IPC: G01N33/58
Filed: 1982-10-04
Abstract: For use in allergy screening, a plurality of filaments (12) coated with different allergens and arranged in a predetermined spaced relationship on a support (10) to provide coincident measurement in a liquid specimen of IgE class antibodies specific for the allergens. The filaments (12) are preferably cotton threads that can covalently bind the allergens through cyanogen bromide induced linkages and the support (10), which can be cut away to reduce background, is preferably composed of a plastic or other water insoluble material, permitting inexpensive and relatively simple manufacturing. After IgE class antibodies present in a liquid sample have reacted with the allergens coated on the filaments (12), they are detected with second antibodies labeled with radioactive, fluorescent or enzymatic tracers. By using a high energy radioactive tracer, such as I<125>, autoradiographic techniques with phosphor screen enhancement allow for diagnostic analysis by densitometers or even the unaided human eye.
Patent ES-8404954-A1 (ES)
Title: Torque limited cap applicating head
IPC: B67B3/20
Filed: 1982-12-16
Abstract: The invention relates to a limited torque applicating mechanism for applying caps to the threaded necks of containers. Torque is transmitted to a conventional cap applicating head from a rotating power shaft by positioning a ring of permanent magnets on either the driven or driving element and disposing a ring of high magnetic permeability material concentrically adjacent on the other of the driven or driving elements so that the torque transmitted between the driving and driven elements is limited by the magnetic attraction between the ring of permanent magnets and the ring of high permeability magnetic material. The apparatus further incorporates a mechanism for adjusting the relative axial position of the ring of permanent magnets with respect to the ring of high magnetic permeability material to permit selective adjustment of the amount of torque transmitted.

Title: Probabilistic learning element
IPC: G06V10/70
Filed: 1985-01-16
Abstract: A probabilistic learning element for performing task independent sequential pattern recognition. The element receives sequences of objects and outputs sequences of recognized states composed of objects. A plurality of memory elements are utilized to store received objects in sequence and for storing in context learned information including previously learned states, objects contained in previously learned states, positional information for each object in a learned state and other predetermined types of knowledge relating to previously learned states and objects contained therein. The element correlates sequences of received objects with learned information relating to previously learned states for providing conditional probabilities to possible sequences of recognized states. The most likely state sequence is determined and outputted as a recognized sequence when the element detects that a state has ended. The memory for storing learned information is a context organized memory including a plurality of tree structures having various types of information stored in nodes thereof with certain of the tree structures including at each node an attribute list referring to other tree structures whereby searching is facilitated and unnecessary searching eliminated. The element derives support coefficients relating to how much information was available when calculating conditional probabilities and support coefficients and conditional probabilities are combined to provide a rating of confidence. When the rating of confidence exceeds a predetermined level, the element is caused to store the outputted recognized state sequence as a learned state sequence with the memories storing various types of knowledge relating to the learned sequence of states.

Abstract: A magnetic core structure (18) for transducer heads (10), generally of the type used in magnetic recording, for data for storage purposes, which, afthough of single-gap form provides operational characteristics similar to those typically found in multi-gap heads. It is thus suitable for use in a bi-directional media transport although having only a single read/write gap. The core stiucture (18) includes a full-width pole piece (20) on one side of the gap, and a partial-width pole piece (28) on the opposite side of the gap additionally, the core structure includes separate magnetic return shunt pieces (26, 30) which are disposed on opposite sides of the partial-width pole piece (28) and extend into communication with the opposite pole piece (20). During writing, the full-width core structure is energized, producing a magnetic circuit which includes both the partial width pole and the shunt pieces. During reading, signals are taken only from flux present in the partial-width pole. Thus, the "write" width is wider than the "read" width.
