Patent DE-4103338-A1 (DE)
Title: Sepn. and orientation of pairs of decorative plates - by removing joined edges and feeding pairs to station with turning table which turns one plate upside down so both face same direction
IPC: B27N3/06
Filed: 1991-02-05
Abstract: A process is desorbed for separating laminates mfd. in pairs with a separating layer between and joined along the edges only by resin. Laminates are fed to a transfer track leading to a laminate turning station containing a turning table. Laminate edges are trimmed off along the transfer track to remove the connecting edge strips. The loose pairs of plants are then fed one after the other to the turning station where they are separated into single plates and individually clamped on the turning table with the rear face upwards. After turning upside down each single plate is delivered, one after the other, rear face downwards from the turning station to a discharging track. USE/ADVANTAGE - The process is used to separate decorative laminates mfd. in pairs with a separating layer and bonded only along the edges and delivers them individually to store with identical orientation.

Patent DE-4123079-A1 (DE)
Title: Threaded fastener assembly - incorporates angle contact face to impact better load distribution along thread
Inventor: MEYER HANS
IPC: F16B39/284
Filed: 1991-07-12
Abstract: In plain nut to bolt interfaces, when the nut is tightened against the contact face a small but important compression of the nut occurs. This leads to an uneven distribution of force throughout the nut thread with the majority carried by the first two threads. This nut incorporates a chamfered face (3') which abuts the contact face. This forces the base of the nut radially outwards. Due to the angled faces of the threads the resulting greater nut diameter decreases the load transmitted to the first threads, producing better load distribution.

Patent DE-4222119-A1 (DE)
Inventor: GILDEMEISTER HANS-HERMANN DR
IPC: B29B17/02
Filed: 1992-07-06
Abstract: During the gravity separation of solid materials according to their density by heavy-liquid flotation in a separating liquid within the centrifugal field of a rotating container, fluctuations in the properties of the suspension and solid materials cause difficulties with respect to the separation accuracy and yield. The disclosed design of the separating device (10) with a retarding disk (20) combined with a conical sieve (16) arranged within the separating device in the area of the separating liquid outlet (19) allows sharply separated outlet areas for the sinks (13) and floats (25) to be obtained, so that it becomes possible to maintain a largely constant separation accuracy and yield in spite of strong changes in the suspension or solid material properties.

Title: Low cost low weight thermally insulating panel for building industry - has sandwich construction with closed-cell PVC foam bonded to polystyrene foam
Inventor: SEITNER BERND
IPC: B32B5/32
Filed: 1992-09-17
Abstract: A sandwich construction sheet, and particularly one for use in the building industry, consists of two different layers bonded together, one being a lightly expanded closed-cell PVC foam; the second layer is polystyrene foam. An example is a wall panel consisting of the PVC foam bonded to extruded polystyrene foam. The back of the polystyrene has a series of parallel grooves to maximise the surface area for applied adhesive. By this means the panel is securely and durably bonded to the wall which requires the thermal insulation. An alternative product has the polystyrene foam as core between two skins of the PVC foam. This has both better thermal insulation and also higher compression and bending strength. ADVANTAGE - The product has good thermal insulation, low weight, high stability, low production cost and ease of working.
