Title: Hydraulically damped door closer - has cylinder bore enlarged in end region to eliminate damping
Inventor: BAECKER ARMIN
IPC: E05F3/10
Filed: 1990-02-21
Abstract: A hydraulically damped door closer consists of a piston (15) with a piston rod (13) which operates in a cylinder (12) which is filled with oil. The door is closed by  a compression spring (14) which is fitted inside the cylinder and acts on the piston. The piston is damped by the flow of oil through an orifice (36) in the piston body. The effective size of this orifice can be varied by adjusting the axial position of the piston on the piston rod. The piston is undamped over the end part of its travel. This effect is produced by enlarging the cylinder bore over its end region. USE - Hydraulically damped door closer.

Abstract: 1. Self-supporting hood for vehicles. 2.1 Self-supporting hoods for vehicles, in particular for railway goods wagons which cover the loading space in conjunction with end walls and, if appropriate, a permanently arranged central gantry and in the closed position are located in a plane, have the disadvantage that the rigidity of the walls, principally when subjected to alternating pressure loads such as occur in railways at high speeds in a tunnel, in particular when trains pass, is not sufficient. 2.2 Self-supporting hoods for vehicles, in particular railway goods wagons, are to be designed in such a way that they withstand high alternating pressure loads and windforces and, if appropriate, serve as a means of securing freight and in their closed position serve as a component which is integrated into the wagon body and has a supporting function. The self-supporting hoods are characterised in that each hood half (4a, b) is composed of a hood frame (11, 12, 13) made of metal profiles and flange elements (14) which are then inserted. 2.3 The hoods according to the invention are preferably used for railway goods wagons. 3.1 Fig. 2 serves to clarify the invention.

Title: Formation of Josephson weak-link junction in ceramic superconductor - by epitaxial deposition of a superconductor film on a substrate having a projecting spine on which a grain boundary is formed
Inventor: HILLENBRAND BERNHARD DIPL PHYS
IPC: H01L39/24
Filed: 1991-03-25
Abstract: A grain boundary Josephson contact in a layer of high temp. ceramic superconductor material (HTS) is formed on a level susbtrate which carries a projecting arched profile (10). The steepness of this profile is sufficiently only near the top (13) to cause the formation of at least one grain boundary in a HTS layer deposited over it. The sharpness of the apex, measured as the angle between 2 lines normal to the surface of the profile near its top, is at least 30 deg., pref. 40-90 deg. The feature claimed is the process for forming the profile. This consists of depositing on a level substrate surface (2a) a structure (3) contg. an elevated masking region (5). The structure is then etched, pref. using ion bombardment, in such a way that also the edges (11a,b) are etched back until the arched profile (10) is obtd. The profile is pref. made of a material which prevents epitaxial depsn. The masking region can be a part of a layer deposited on the susbtrate, or can be deposited directly on the substrate surface and formed of the defects inducing material. Before deposition of the epitaxial HTS layer a diffusion masking layer may be deposited. USE/ADVANTAGE - The process results in a device with at least one Josephson grain boundary junction, using the WEAK LINK principle. The method is used e.g. to form SQUID devices. The etching method provides a reproducible method to form several profiles on a single substrate, allowing multiple devices or arrays to be mfd.
