Patent EP-0056663-A2 (EP)
Inventor: SCHREMP EDWARD JAY
IPC: F03B13/12
Filed: 1978-12-06
Abstract: New and improved methods and means are described for the efficient, expeditious, economical, and safe conversion to usable form of almost all subsurface wave energy available within a predetermined annular region spanned by an array of submerged wave energy removing impellers mounted upon an annular outrigger surrounding and secured to a seagoing central platform. Maximal progressive inward attenuation of practically any state of the open sea is achieved over a very broad wave frequency band by buoyant, nonbuoyant, and neutrally buoyant impellers that function approximately as generalized simple pendulums whose natural frequencies fall at regular intervals throughout that frequency band. Optimal functioning of the impellers is achieved by assigning to their working members suitable degrees of omnidirectional response to water movement inertial and drag forces, respectively. After conversion by pumps, the extracted wave energy is conveyed via a pressure transmission subsystem to a central turbine for further conversion and subsequent storage and / or product processing within the central platform.

Abstract: For protection of an output switching transistor used in a pulse signal output circuit, the present invention provides a first detector for detecting over-current flowing through the output switching element, a second detection circuit for producing a detection signal in response to detection of over-current by the first detector in excess of a predetermined rate, and a protection circuit protecting the output switching element by suppressing the current flowing therethrough in response to the detection signal. The protection circuit may suppress the current flowing through the output switching element by both the output of the over- current detector and the detection signal.

Abstract: A multilayered structure is described that is useful in making containers, the structure having at least one low gas permeable layer specifically located in the multilayered structure so that there is substantial reduction in the formation of unwanted inclusions formed during coextrusion processes. In particular, the structure is a tubular body which comprises a plurality of layers of different polymeric materials united or bonded together, said structure having at least one uncentered layer of low gas permeability, said layer having an average thickness in the range of about 1 to 20 percent of the total thickness of the body. The structure may be readily made by forming a series of melted thermoplastic streams, enveloping the series of melted streams to successively form separate and defined layers one upon the other, and introducing a layer of low gas permeable material into the series proximate the exterior portion of the structure. The low gas permeable material may be polyvinylidene chloride copolymer, poly(vinyl alcohol-coethylene) or acrylonitrile-containing polymers.

Abstract: A mixture of a diol containing ionizable groups and of a polyol-polyester or polyol-poly ether is reacted with an aromatic or aliphatic or cycloaliphatic isocyanate, thereby obtaining a prepolymer with terminal isocyanic groups. The latter is reacted with a hydroxy-alkyl-acrylate or-methacrylate, so as to obtain an oligo-urethane having unsaturated terminal groups. The thus obtained product, after having been subjected to salification, dispersed in water and subjected to polymerization in the presence of a redical catalyst, gives rise to a stable aqueous dispersion of polyurethane, suitable for forming coating films, or for use as a dressing or adhesive.

Abstract: A system for use in the treatment of paralyzed muscles is disclosed. The system makes use of a set of transcutaneous electrodes (15a, 15b, 15c) which are placed upon the skin of the subject over muscles which are to be stimulated. A computer controlled stimulator (50) generates a pair of alternately pulsed stimulation signals which are applied across different pairs of stimulation electrodes (15a, 15c and 15b, 1 5c) to produce controlled muscle contraction. Muscle movement is resisted by a dynamic load (27), and a position sensor (17) provides a feedback signal indicating the movement actually achivied. The computer (13) uses the feedback signal for modifying the control signal applied to the stimulator.

Abstract: This invention relates to diffusion transfer processes and products wherein the transmission density of the pigmented processing composition layer is increased by employing an alkali earth metal salt to increase the light-absorbing ability of a carboxynaphthol phthalein optical filter agent within said processing composition layer. In another embodiment, a carboxyindole phthalein optical filter agent also is included in said processing composition layer, and a zinc or cadmium salt is employed to shift the spectral absorption of the carboxyindole phthalein into the green region of the visible spectrum. In a further embodiment, a calcium salt is employed in a viscous pigmented processing composition comprising a light-reflecting pigment, colloidal silica and a metal chelating agent, e.g., an alkylene polyamine polyacetic acid to stabilize the spreading characteristics of the composition.

Abstract: For the dimension and irregularity inspection of the edges of solid bodies delimited by at least two plane and parallel surface, the body itself is struck by a blade laser beam which is slanted with respect to the side of the body and is formed by parallel rays on a perpendicular plane to the surface planes of the body. The beam which is reflected back from the side of the body is received by a TV camera through a reflecting mirror, so that the TV camera receives the dimensions of the lateral height while a second TV camera, aligned with the axis of the body, receives the diffracted rays from the upper edge thereby enabling a control of the dimensions and any irregularies present.

Abstract: In order to control and supervise transport arrangements with several track transport vehicles on a common track divided up into sections, track areas are reserved at certain times for the exclusive use of particular transport vehicles. The execution of a transport is transmitted to a transport vehicle in the "waiting" state, an area of associated track sections required for the execution of the transport being reserved for this transport vehicle (Figure 1). A precondition for the transmission of the transport order is that the required track area can be reserved. The reservation is cancelled again after the termination of the transport. If two or more adjacent transport vehicles cannot carry out any further transports since they are mutually blocking the required track areas, these transport vehicles, with the exception of one, are moved so far that the track area required for the execution of a transport becomes free for this one vehicle.
