Abstract:
A method for replacing a fuse casing (4), which is riveted to the casing (2) of an active component (1) containing an explosive charge (3). The new fuse casing (4) laser-welded to the remaining rivet parts (5) of the active component casing (2). Welding filler materials are used to attach the new fuse casing (4) easily and securely to the active component casing (2), such that the connection can withstand even high firing accelerations, without this resulting in impermissibly high thermal stress to the explosive charge (3) in the active component. Welding powders (7) or welding pastes can be used as welding filler materials, which are inserted into gaps (8) remaining between the remaining rivet parts (5) and the bores (6) in the fuse casing (4) before the remaining rivet parts (5) are welded to the fuse casing (4). Also used are discs (9) that cover the bore holes (6) in the fuse casing (4). The disks are placed onto the frontal faces of the remaining rivet parts (5) and are welded to these.
Abstract:
To regulate a single sideband up converter having a pair of mixer stages (M1, M2), each mixer stage receives control signals to compensate for spurious signals of the mixer components. Part of the radio frequency output signal (RF') from the converter is fed to a down converter (M3). From the resulting down-converted signal, the original intermediate frequency signal (IF) as well as the first harmonic thereof are filtered out as a measure of oscillator and sideband suppression. From these filtered-out signals, control signals for the mixer stages (M1, M2) are obtained.
Abstract:
5-Acetoacetylamino benzimidazolone-(2) is obtained in high yield and excellent purity by reacting diketene with the aqueous solution of a salt of 5-amino-benzimidazolone-(2) and an acid having a pKa value of 1 to 7, preferably in the presence of an antioxidant and/or a reducing agent.
Abstract:
A portable dialysis device that can be continuously worn in and/or on the body of a patient, with a blood chamber in which the patient's blood can be received, a hydraulic chamber which can be filled with a hydraulic fluid and which adjoins the blood chamber, an at least partially flexible delivery membrane which is arranged between the hydraulic chamber and the blood chamber and which, when the hydraulic chamber is filled with hydraulic fluid, is movable in the direction of the blood chamber in such a way as to cause a compression of the blood chamber and therefore an ejection of the blood located therein, a pump for controllable filling and/or emptying of the hydraulic fluid in the hydraulic chamber, such that blood can in this way be conveyed into the blood chamber and/or out of the latter, a filter membrane which is arranged between the blood chamber and the hydraulic chamber and through which waste substances in the blood can be removed to the hydraulic fluid located in the hydraulic chamber, such that the hydraulic fluid serves at the same time as dialysate. Additionally, a method for operating a portable dialysis device.
Abstract:
According to one embodiment, a dialysis device is made available that can be implanted at least partially into the body of a patient and comprises a blood chamber, through which the patient's blood can flow, a dialysis chamber for receiving a dialysate, and a hydraulic pump device for compressing the two chambers alternately by means of a hydraulic fluid, wherein both chambers are each equipped with two valves for controlling the inflow and outflow of blood and dialysate, respectively, and wherein both chambers are connected to each other in an area designed as a membrane.
Abstract:
For connecting a cardiac biventricular assist means including a dual-chamber pumping device, and an electrically powered compressor means provided between the two chambers (12, 15) a partially flexible one-part or multi-part adapter (20) is provided with two through-passageways (21, 22; 34, 35) each separate from the other, said adapter being securely held, on the one hand, in a port (4a) in the apical portion of the septum (4) and, on the other, in a port (2a) in/at the apex of the left ventricle (2) so that the through-passageway (22; 35) extending into the left ventricle (2) is connected directly or by means of a first flexible tube (11) to the inlet (12a) of the one chamber (12) and the other through-passageway (21; 34) extending into said right ventricle (3) is connected directly or by means of a second flexible tube (14) to the inlet (15a) of the other chamber (15).

Abstract:
A fully implantable left ventricular assist system comprising a pumping means connectable via adapter elements to the ventricle includes two compressible chambers in the form of sacs (5, 5′) and a compressing means (4) to alternatingly fill and discharge the compressible chambers (5, 5′) at the same time, including a drive unit (41) assigned thereto, a cooling means (50) for cooling the drive unit (41), and a power supply unit (60) for the drive unit (41) and cooling means (50).In this implantable system the pumping means, compression means (4), drive unit (41) and part of the cooling means (50) are accommodated in a two-part housing (1) on which tubular ports (10a, 10b; 10′a, 10′b) for connecting Y-shaped adapter elements (3, 3′) are configured.
