Title: One-step mixing and activation of plaster mortar components - by comminuting with vibration or pinned disk mills
Inventor: ENTZMANN KARL DIPL ING DR TECH
IPC: B31B1/90
Filed: 1978-06-26
Abstract: An activated plaster mortar is produced contg. >=1 active and one inactive component. At the same time as the main mixing step the components undergo a commination by means of an impact effect on the particles. The particles receive 3-8 blos or impulses within 10-2-10-3 secs. This mechanochemical change in the fine structure increases the reactivity of the components enabling high strength and elasticity to be obtd. rapidly during the setting process. PRef. the activation step takes place in the mixing appts. by means of a pinned disc mill ("disintegrator") or a vibration mill. Premixed plaster mortar is obtd. with improved properties which it keeps until the use of the mortar, e.g., better adhesion to the wall surface. Using this technique it is possible to add metal powder to the mortar with a uniform distribution.

Title: Cupboard door hinge with self closing action - is tensioned by eccentrically mounted arm assisted by enclosed leaf spring
Inventor: REDEN MANFRED VON DIPL ING
IPC: E05D7/04
Filed: 1978-08-26
Abstract: The hinge for a cupboard door operates with spring action when fully opened or fully closed, thus holding the door opener shut. This spring force is applied by an eccentrically mounted arm which is pulled against the hinge half (5) which is mounted inside the cupboard. This force is also increased by a leaf spring (25) housed inside the hinge assembly. The eccentric arm rotates about the head of a spindle (12) passing through a slot (11) in the hinge half (5). The latter is pulled against a block (1) with threaded inserts (13, 14) which are fitted into holes in the cupboard side, and can slide sidways for adjustment. The spindle has an externally threaded stem which passes through the block (1) to screw into a collar (29) on the leaf spring which is housed inside the block thus pulling the eccentric arm inwards.

Title: Flat spring suspension for seats in vehicles - has differently biased springs supporting frame for high stability and comfort
Inventor: PAULISCH HEINZ
IPC: B60N2/54
Filed: 1978-10-04
Abstract: The suspension for the seat is formed by a seat frame which is attached by one transverse beam to the basic framework. There is a hoop (5) attached to the seat frame (2) to extend in the direction of the beam (3). The seat frame (2) and hoop (5) are supported with different springs so that the springs (8) placed on the side of the front edge of the seat have a greater softness than the springs (7) at the rear edge of the seat, irrespective of the position of the axes at the connecting points. Although the spring suspension has an extremely flat structure it offers a high comfort since the seat area taking most of the body weight has harder springs than the edge areas.

Title: Trapezoid metal plate sliding roof span - has connecting bar on chords for pressure and tension absorption
Inventor: FEDEROLF SIGHART DIPL ING
IPC: E04B5/43
Filed: 1979-01-20
Abstract: The roof unit is made up from one or more trapezoid sheet metal profile plates forming a span which can be pushed sideways, wit its lower or upper chords connected to end supports.

Title: Miniature wound capacitor - with thin encapsulation of specified water vapour permeability
Inventor: MAYLANDT HELMUT DIPL ING
IPC: H01G2/12
Filed: 1979-08-03
Abstract: A miniature capacitor with metallised plastic foils is encapsulated in an electrically insulating material which protects it against mechanical, thermal and chemical agencies. The enclosure is permeable to water vapour at least to such a degree that at all values of the relative humidity which may occur during the operation of the capacitor and at any moisture content of the foil stack, the moisture can be diffused outwards as fast as with no encapsulation. This combines a rapid adaptation to climatic changes with a compact design and maximum protection against extraneous interference.

Title: Stepper motor with stator-rotor gear coupling - has bellows spring coupling between rotor and drive shaft to damp irregularities
Inventor: RUFF GERD
IPC: H02K41/00
Filed: 1980-05-16
Abstract: The modification to a stepper motor with a wobble plate rotor is intended to damp out irregularities in the drive caused by meshing of the rotor and stator teeth. The stator (1) with its magnet poles (2) and windings (3) has a ring of teeth (4). The rotor (6) has a corresponding ring of teeth (5), and there is a difference of at least one tooth between the two rings. As the stator poles are successively energised the rotor is drawn axially towards the stator at the point of the magnetised pole. The tooth difference at meshing then imparts motion to the rotor. The rotor is mounted on a self-aligning bearing (8) and is coupled to the drive shaft (10) by a spring bellows (11). This has a high torsional stiffness and a constant angular spring constant around its perimeter. It acts as a damper to give more accurate angular movement of the drive shaft.

Title: Flat headlamp glass for motor vehicle - is made as glass pressing in open mould with subsequently removal of surplus material
Inventor: WALTHER HORST-JUERGEN
IPC: F21V5/00
Filed: 1980-05-16
Abstract: The object of the proposed method of headlamp glass manufacture is to reduce the weight of the assembly. This is achieved by eliminating the flange round the glass by which it is attached to the reflector or carrying plate. The required optical form and outline are produced by pressing molten glass (3) between two plates (1,2). One of these (1) has the contours required for the optical form of the finished headlamp glass. When cool the surplus (4) is cut away by a suitable process and the resulting sharp edges removed. The glass pressing is typically made with a flat rim onto which the headlamp reflector and mounting for the complete lamp assembly can be attached by means of a suitable adhesive. adhesive. Use of a flat glass lends itself to subsequent annealing or heat treatment.
