Patent ES-439584-A1 (ES)
Title: Differential charge transfer sense amplifier
IPC: G11C11/24
Filed: 1975-07-21
Abstract: A differential charge transfer amplifier which functions as a sensing and regenerating circuit responsive to binary information represented by the level of charge in a stored charge memory cell is disclosed. The sense amplifier includes a pair of dummy cells and bucket brigade amplifiers which are connected on either side of a dynamic latching circuit which includes a plurality of actuable gate devices, which may be field effect transistors. A bit/sense line of the array is divided into two equal sections which are respectively connected to either side of the sense amplifier. The operation of the amplifier is cyclic, including a precharge period, a sensing period, a rewrite period and a restore period, after which the amplifier is in its original state. A feature of the amplifier is that it consumes no d.c. power other than leakage and has high sensitivity due to a charge transfer feature. Also, during the operation of the circuit, energy remaining in one of the bit line sections after rewriting is utilized to pre-bias both bit line sections to an initial level. As a result, this allows better control of the precharge level on the bit/sense line and in so doing, the power requirements are substantially reduced. At the same time, a dummy cell is charged to the potential of the now balanced bit lines.

Patent ES-467261-A1 (ES)
Title: Vacuum flask
IPC: A47J41/00
Filed: 1978-02-23
Abstract: In a flask comprising a closed vessel with double walls enclosing a vacuum, layers of substances capable of absorbing light-rays and/or of selectively acting upon light-rays are applied to enable more radiant energy to reach the space enclosed by the inner wall than that space can radiate to the outside. Thus an increasing amount of heat is supplied to the space enclosed by the inner wall, and cold matter introduced into that space is heated. The effect of the light-rays can be increased by designing part of a protective jacket of the flask so that it is capable of being swung open and of acting as a reflector in that position.

Title: Pomp for supplying fluid to a system.
IPC: F04C13/00
Filed: 1982-05-06
Abstract: A pump includes a rotor, a cam encircling said rotor and means for effecting relative rotation of the cam and rotor about an axis. A plurality of vanes are carried by the rotor and engage the cam to define pumping pockets which expand and contract on rotation of the rotor. A cheek plate is movable along the rotational axis to communicate expanding and contracting pumping pockets. There is a cavity on one side of the cheek plate, and a fluid passage conducts fluid pressure into the cavity which fluid pressure biases the cheek plate into a position blocking the flow of fluid from the contracting pumping pockets to the expanding pumping pockets. The pump also includes a servo valve for venting the pressure in the cavity to thereby control the flow of fluid between the contracting and expanding pumping pockets. A fluid passage in the cheek plate receives flow from the contracting pockets. The passage has a portion directing flow from the contracting pumping pockets radially inwardly of the cheek plate. A tubular member is fixedly attached to the cheek plate coaxially with the axis of relative rotation of the rotor, and the interior of the tubular member communicates with the portion of the fluid passage directing flow radially inwardly.

Filed: 1982-08-23
Abstract: A metod for preparing an aortic heart valve for implantation wherein the area of the septai shelf (18, 19) of the right coronary cusp extending into the valve orifice is substantially reduced. The excised vaive (10) is prepared for fixation by pressurizing) the valve to close the valve cusps (20, 21), and thereafter inverting the aortic vesituble tissue (12) over a valve stent (17) or other cylindrical form circumscribing the valve. As the vestibule tissue is inverted, the septal shelf muscle is pulled toward the outside wall of the valve. When the septal shelf has been displaced to the maximum extent possible while maintaining coaption of the valve leaflets the valve is fixed with a tanning solution. The resulting valve, after being trimmed and mounted for implantation, has improved flow characteristics.

Title: Heterocyclic compounds, their preparation, cosmetic preparations containing them and their use in hair and skin care.
IPC: C07D495/04
Filed: 1982-12-09
Abstract: Biotin esters, namely biotin C2-4-alkyl esters, are prepared by esterifying biotin with a C2-4-alkanol. These esters have the capability of being absorbed by the human skin better than biotin and are converted into biotin during or after absorption. Since biotin itself promotes the fat and cholesterol synthesis of the skin, the novel biotin esters of this invention are useful as active ingredients for cosmetic hair-care and skin-care compositions.
