Abstract: Device for establishing such a galvanic connection between conductors of a first batch and conductors of a second batch that on the one hand signal transmission between the two batches can take place undisturbed, and on the other hand transmission consequent on inducing electro-magnetic radiation will be blocked in two respects. High voltage induced in the conductors of the first batch consequent on high-energetic radiation, which manifests itself as a pulse, is reduced in stages to a relatively low residual voltage on the conductors of the second batch. Besides voltages induced either in the conductors of the first batch or in the conductors of the second batch, consequent on electromagnetic radiation having a signal character, are strongly reduced, in such a way that the conductors of the relevant other batch (either the second or the first) will not cause a detectable corresponding radiation. For that purpose an LD-filter configuration with one or two T-sections connected in cascade has been connected between each pair of corresponding conductors. In one of these T-sections a coil, which also forms part of a high- voltage reducing section, has been utilized. The device is mounted in a housing, which blocks electromagnetic radiation and can be fixed to a wall of a Faraday cage room in such a way that an opening in that wall will be closed. In this manner electric conductors extending to the interior of the Faraday cage room can be connected, in the desired way, to electric conductors establishing a connection with the outer world.

Abstract: Human myelin basic protein (h-MBP) has a molecular weight of 18.5 KD and contains 170 amino acid residues. Synthetic peptides ranging in length from about 8 to 25 residues and covering the entire length of the protein have been produced. Antibodies to h-MBP (anti-MBP) were found to be neutralized by the synthetic peptides, in vitro, which span the h-MBP from about amino acid residue 61 to about amino acid residue 106. The peptides, which cover both the amino (about residues 1 to 63) and carboxy (about residues 117 to 162) terminals of h-MBP did not neutralize purified anti-MBP. Intrathecal administration of peptide MBP75-95, either as a single dose, or as repeated injections for periods up to 10 weeks, produced complete binding-neutralization of free (F) anti-MBP with no change in bound (B) levels. A control peptide MBP35-58 had no effect on F or B anti-MBP levels. Intravenous administration of MBP75-95 resulted in significant decline of F and B CSF anti-MBP levels over a period of one month. Administration of MBP synthetic peptides to MS patients either intrathecally or intravenously did not have any adverse neurological effects and systemic complications did not occur. The MBP epitope for MS anti-MBP has been localized to an area between Pro85 and Pro96.

Abstract: A piston for separating the hydraulic side (14) of a pressure storage reservoir from a gas side (16) has piston sealing rings (18,20) of elastomer or of any other suitable sealing material. To protect the sealing rings from damage by debris in the hydraulic fluid a special felt ring (24) is fitted around the piston as the first ring seal to the hydraulic side. The felt collects any debris in the hydraulic fluid and ensures that only filtered fluid reaches the elastomer sealing rings. The main piston can be supplemented by a secondary piston on the gas side of the main piston, and connected to the main piston by a sprung coupling. The space between the two pistons is filled with clean hydraulic fluid.

Abstract: A new ZVS (zero-voltage-switching) snubber circuit suitable for high power boost converters used as power factor correction circuits used in AC-to-DC modules. The ZVS circuit comprises a main switch, an auxiliary switch, a load circuit, a reset circuit, a first diode, a blocking diode, and a first capacitor. The switches and the capacitor are connected in parallel. The circuit includes a blocking diode having an anode terminal connected to a drain terminal of the auxiliary switch and a cathode terminal connected to the reset circuit. At turn-off, the current tail of the main switch is taken over by the auxiliary switch. The ZVS circuit keeps the collector-emitter voltage of main switch almost zero, so that the turn-off loss is minimized.
