Patent DE-3805895-C1 (DE)
Title: Laboratory cabinet with removable door
IPC: E05D7/10
Filed: 1988-02-25
Granted: 1989-07-27
Abstract: The invention comprises laboratory cabinets, in particular electrically heated laboratory cabinets, with at least one door which is pivotable with a vertical axis and removable and is held by two hinge bearings arranged at a distance from one another. The hinge bearing consists of a bearing element with a disc-shaped part having a bore. The pin, which is immovably fixed to a holding element, reaches into this bore. The holding element has a lug which grips behind the underside of the disc-shaped part of the bearing element. The disc-shaped part of the bearing element has a groove. The latter releases the lug of the holding element in a given position of the door, preferably in the approximately closed state of the door, with the result that the door can be easily removed without the aid of tools.
Patent DE-3814618-C1 (DE)
IPC: A61M25/00
Filed: 1988-04-29
Granted: 1989-02-02
Abstract: The introduction equipment consists of an inner sleeve (10), an intermediate sleeve (20) and an outer sleeve (30), which are made of flexible material and surround each other in a coaxial manner. The inner sleeve (10) has a proximal end section (11) with handle (12) and a thickened distal end section (13), which tapers conically towards its free end and bears a proximal outer shoulder (15). The intermediate sleeve (20) has a proximal end section (21) and a distal end section (22), whose outer diameter is at least as great as the outer diameter of the proximal outer shoulder (15) of the distal end section (13) of the inner sleeve (10). The outer sleeve (30) has a proximal end section (31) with handle (32) and seals (34) and a slightly conically tapering distal end section (33) which can be radially elastically expanded, the outer diameter at the free end of the distal end section (33) of the outer sleeve (30) being slightly smaller than or equal to the outer diameter of the end section (13) at its outer shoulder (15). In this arrangement, the cross-section of the introduction equipment increases from the distal end gradually and continuously, which allows the introduction equipment to be inserted without difficulties into the opening of a vessel. The intermediate sleeve (20) prevents the withdrawal of the inner sleeve (10) after the positioning of the introduction equipment, while it slightly widens the distal end section (33) of the outer sleeve (30) and passes through the proximal end section (13) of the inner sleeve (10).

Title: Electrical plug contact part
Inventor: SCHROEDER GEORG
IPC: H01R13/187
Filed: 1989-03-02
Granted: 1990-01-18
Abstract: An electrical plug contact part is proposed which consists essentially of a connecting region which is provided for connection through an electrical cable, and of a contact region which is connected thereto and is provided for accommodating a mating plug-contact part. The contact region in this case consists of a retaining body in which a contact recess is provided centrally to which a contact spring means is assigned in a retaining manner. In order to create a plug contact part which is able to produce high contact forces and to pass on or dissipate thermal energy to a large extent, the connecting region and the retaining body are produced integrally from solid material, the foot of the contact recess having a thickened region. The contact spring means is folded about its line of symmetry running through the base and, in the region of its line of symmetry, has a bulge corresponding to the thickened region of the contact recess. In this case, the contact spring means is held in a positively locking and force-fitting manner in the thickened region of the contact recess via this bulge.

Title: Non-contact measurement of salt on roads to prevent costs of over application
Inventor: BLASEK GERHARD PROF DR RER NAT
IPC: G01N21/67
Filed: 1994-12-24
Granted: 1996-04-18
Abstract: The concn. of salt on roads is measured by a novel non-contact method, allowing measurements to be made in motion. A discharge is released between an electrode (3), and the salt-contg. water layer (2) on the road (1). The water is vaporised, carrying salt into the discharge path, exciting the atoms to light emission. Emission intensity is electrically measured and evaluated, as a function of wavelength.  Also claimed is the appts. suitable for the above method. The high tension generator (4) supplies the electrode (3); emissions from the sparks being collimated (5) into the optical fibre (6). Spectral discrimination (7') is followed by the optical transducer (7), which feeds the measurement circuit (8). Further equipment converts the electrical signal into the measurement of salt concn..
