Patent EP-0272024-A3 (EP)
IPC: B29C43/12
Filed: 1987-12-04
Abstract: There is disclosed a method and apparatus for 
the production of a shell-like moulding from a fabric 
faced laminate. The laminate is forced against the 
surface of a mould cavity by one or more membranes which 
are inflated on the side of the laminate remote from the 
mould cavity. Movement of the laminate towards the 
surface of the cavity can be assisted by vacuum suction 
applied within the cavity and by mechanical means which 
carry selected areas of the laminate into engagement 
with the surface of the mould cavity prior to inflation 
of any membrane.

Title: Switch apparatus, in particular a contactor
IPC: H01H50/64
Filed: 1989-08-17
Abstract: The invention relates to an electromagnetic switch apparatus having a magnet system with yoke and armature, the armature of which has switch contact parts lying mutually adjacent transverse to the direction of actuation with a contact support guided in the casing of the switch apparatus, which switch contact parts form normally-open or normally-closed contacts with stationary contact parts, and in which support or entrainment stops are provided for the switch contact parts. 
<??>The contact supports are guided in the housing with play, so that tilting is possible. With respect to this tilting motion, the free path, that is to say the path which is necessary from the lifting of all normally-closed contacts to the resting of all normally-open contacts, must be set to the normally-closed contact lifting last. 
<??>In order to keep this free path relatively large, the stops facing the casing walls are located in advance of the middle stops in the direction of motion, so that the free path lost by the tilting is thereby gained again. In this way, the force required can be kept lower in comparison to the conventional design, since it has a favourable effect on the traction curve.

AlxGa(1-x)As third 
current blocking layer (7) is formed over the second 
current blocking layer (6) and the portions of the first current 
blocking layer (5) not covered by the second current blocking layer (6). 
The variation of the width of the groove (10) is provided by placing 
a wafer with the groove formed in the first current blocking layer (5) 
in a metal organic thermal decomposition crystal deposition 
apparatus and heating it, while causing hydrogen chloride to flow, 
or placing the wafer in a molecular beam epitaxial deposition 
apparatus and heating it while irradiating with an arsenic 
molecular beam, or by placing a liquid-phase epitaxial deposition
