Abstract: ABSTRACT OF THE DISCLOSURE           Alcohol preparation from grain is described, in which the fat degradation and the saccharification of the mash is carried out in two separate steps with an intermediate filtra-tion.  In the first step the wet-milled grain is degraded with amylolytic enzyme, then filtered, and the protein and fiber-containing filter cake used directly or dried as fodder material.          The filtrate is then treated to an acid and/or enzymatic saccha-rification and used without further filtration in the fermenta-tion.

Title: Bi-directional filter system for amplifying signals in separate frequency bands
Inventor: KAEGEBEIN DANIEL P
IPC: H04B3/38
Filed: 1980-11-10
Granted: 1983-08-02
Abstract: A two way repeater-amplifier for amplifying one or more signals of a first group propagating in a first direction and one or more signals of a second group propagating in the opposite direction is proposed. The repeater-amplifier utilizes a single amplifier disposed to receive signals from first and second filter networks adapted to pass signals within the first and second groups respectively. Third and fourth filter networks are disposed to receive signals from the output of said amplifier and are adapted to pass signals within the second and first groups respectively. Tuned cables cooperate with the networks to route only the first signals through the first network, the amplifier and the fourth network, while other tuned cables cooperate with the networks to route only the second signals through the second network, the amplifier and the third network.

In a preferred embodiment, the lens is homocentric, with the common center of curvature of the inner and outer surfaces of the lens being located at a relatively small acoustic aperture in the body so that object points distributed over a relatively large solid angle from the aperture can be imaged with minimum lens aberations.  Where the object to be imaged is a human heart, the acoustic aperture is most conveniently located at an intercostal space between adjacent ribs.

Abstract: MULTILAYER FILM MANUFACTURE UTILIZING SCRAP RESIN                 ABSTRACT OF THE DISCLOSURE          A novel system for producing film by extruding and/or casting at least two layers of resin, such as polyacrylonitrile homopolymer or interpolymers.  The system provides for co-extruding a continuous multi-layer film with contiguous  or tandem dies from a first supply of homogeneous resin solution and a second supply of non-homogeneous redissolved resin scrap.  The film may be cast onto a smooth cooled drum surface to form substantially continuous adjacent layers from two or more resin supplies.  By stripping the film from the drum as a continuous film strip and stretching the film an oriented structure is provided.  Scrap resin, such as selvage trimmed from the stretched film or mill scrap, is comminuted and redissolved in solvent for recycle to the second supply of the extrusion step.  The homogeneous layer prevents film disruption by inhomogeneities present in the contiguous layer containing redissolved scrap, which might cause localized stresses in the film and discontinuities during stretching.

Abstract: ABSTRACT OF THE DISCLOSURE     An electronic ergometer whose housing accommodates therein, appropriately connected with each other, a transducer for converting the oscillations of the body center of gravity of an individual into an electrical signal, a pulse shaper, an adjustable high-frequency multivibrator, a frequency divider, a first counter, an indicator, a second counter, an adjustable timer, a register, a power indication enabling  unit, an indic-ation switching unit, a low-frequency multivibrator, a mixer, the electronic ergometer further comprising an ECG sensing unit, an arrythmia signal generating means and a monostable multi-vibrator, a unit for enabling indication of power at which an arrythmia occurs, a storage unit, a reversible counter, a dis-tributor, a read-out unit and an OR circuit.  The electronic ergometer permits to measure the magnitude of physical load (power) at which an arrythmia occurs.  It is possible to deter-mine the work performed by an individual with due regard for the rate of movement and anthropometric parameters of the in-dividual.  The electronic ergometer differentiates between dangerous and non-dangerous kinds of arrythmia.  The non-dangerous kinds of arrythmia are recorded in memory with simul-taneous storing of the value of physical load at which they occurred while the dangerous kinds of arrythmia are immediately displayed with a simultaneous generation  of a sound signal informing the individual of the need to relieve the physical load.  As distinct from prior art devices, the herein disclosed electronic ergometer permits to simultaneously monitor the magnitude of physical load and heat activity in everyday life, while walking or jogging.  This facilitates objective moni-toring of physical loads during preventive treatment or re-habilitation.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for the electroplating of metal strips, and more particularly for the zinc-coating of steel strip, which comprises a tank that is filled with electrolyte liquid, and, immersed therein, at least one electrode disposed above the strip and at least one electrode disposed below the strip, both parallel thereto, wherein the electrode disposed above the strip is made of the metal to be deposited, for example, zinc, and the electrode disposed below the strip consists of a material that is insoluble in the electrolyte and is disconnectable from the current source for the purpose of one-sided electroplating.          Thus, the ions necessary for coating are supplied by the consumable electrode disposed above the strip, both in one-sided and in two-sided coating.  The costly working up of the electrolyte in separate equipment and the recirculating which requires additional energy are dispensed with in the apparatus of the invention.  Since the electrode disposed below the strip, which is accessible only with difficulty, consists of a material that is not soluble in the electrolyte, its spacing from the strip remains unchanged, and uniform coating is therefore assured.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention provides a process for fractionation of compounds, which in essentially non-polar solvents form mixed or co-micelles, and hence  cannot normally be fractionated by membrane filtration.  By dissolving a mixture of such compounds in a solvent system in which selective micelles formation occurs, and contacting the solution under pressure with a semipermeable membrane to separate the mixture into a permeate and a retentate, fractionation of the compound mixture can be achieved, i.e. a fraction enriched in one of said compounds can be recovered from the permeate and/or retentate by re-oving solvent therefrom.  The new process is in partic-ular useful for fractionating phosphatides-containing mixtures into a fraction enriched in phosphatidyl choline by ultrafiltration of a solution of the mixture in a solvent system comprising an essentially non-polar solvent and a polar solvent. e.g. hexane-ethanol, etc. through a semipermeable membrane, and recovering a frac-tion enriched in phosphatidyl choline from the permeate. A fraction enriched in phosphatidyl inositol can be re-covered from the retentate.
