Title: Shock-absorbing laminate - has harder layer of reinforcement penetrating into other softer layers esp. of rubber
Inventor: MAIGLER OTTO KARL BORROMEUS
IPC: B32B7/022
Filed: 1976-01-24
Abstract: A resilient and elastic laminate comprises a number of layers of materials, laid one over another and firmly connected together; different layers possess different hardnesses and elasticities. At least one of the constituent layers has materials of a different degree of hardness penetrating into and engaging into it. In one pref. embodiment, the covering layers have projections which penetrate into a central layer of different hardness and elasticity, thus anchoring them into it. In particular, the penetration may have mushroom-shaped heads. The main material (other than the reinforcement) may be of rubber, more specifically a laminate comprising a covering layer having a shore hardness of 20-100, with softer layers of shore hardness 20-60. The reinforcing inlay may be of metal, glass fibre, plastics fibre, textile fibre. Used for all types of shock absorber, in particular for high frequency vibrations.

Patent DE-2612927-A1 (DE)
Title: Industrial microwave oven with energy distribution - avoids cracks in objects due to shrinkage or expansion by using rotating field to alter energy pattern
Inventor: FRITZ KARL DR
IPC: H05B6/80
Filed: 1976-03-26
Abstract: The industrial microwave oven, for e.g. drying ceramic objects and polymerising plastics, has its internal field distributed so that fractures are avoided. With objects that expand, the energy directed to the centre of the object is given preference over the energy at the edge; whilst for objects that contract, the reverse is the case. This object-specific energy distribution is achieved by rotating the microwave field relative to the object about an axis passing through the object such that the centre and the peripheral regions of the object receive different amounts of energy. Long objects can also be moved backwards and forwards in the rotating field.
Patent DE-2614929-A1 (DE)
Title: Hollow valve piston water mixing tap - has diffuser mesh bushes for reducing water flow noises
Inventor: ZWINK HELMUT
IPC: F16K47/02
Filed: 1976-04-07
Abstract: A hot and cold water mixing tap has a hollow valve piston (6) which is located inside the valve bush (1). The valve bush (1) and the valve piston have two identical sets of transverse holes (2-5) and (7-10). By axially moving or rotating the hollow valve piston (6), the mixing ratio as well as the flow volume of water through the valve can be regulated. In order to reduce water flow noise inside the valve, two concentric mesh-sleeves (17, 18) are located inside the hollow valve piston (6). Thus the incoming water flows through mesh (17) when entering the valve piston. In order to reach the exit ports (4, 5) on the valve bush (1), the water has to flow through a second mesh sleeve (18). Since the flow pattern is diffused, it produces little noise.

Title: Integrated circuit dielectric base - has circuit components in monocrystalline semiconductor islands covered with polycrystalline semiconductor layer
Inventor: MIMURA AKIO
IPC: H01L21/762
Filed: 1976-05-11
Abstract: Circuit components are produced in monocrystalline semiconductor islands covered with a polycrystalline semiconductor layer, with a dielectric layer between the layer and the islands to insulate the layer from the islands and the islands from each other. A dielectric layer is deposited on a monocrystal chip with a groove pattern. At least two polycrystalline layers and at least one oxygen diffusion barrier layer are deposited on the dielectric layer, so that the outermost layer is a plycrystalline semiconductor layer, and the opposite plane main surface is removed up to the single crystal islands. The outer surface of the outermost polycrystalline semiconductor layer (14c) is ground off to a thickness (x) sufficient to prevent a disturbing curvature of the insulating layer below it due to oxygen diffusion into the outer polycrystalline layer.

Title: Light tapping device for multimode optical fibres - involves connecting fibre to section with alternating curves thus inducing mode transpositions
Inventor: JEUNHOMME LUC
IPC: G02B6/28
Filed: 1976-11-29
Abstract: The by-pass or tapping device for multimode optical fibres, comprising a core surrounded by a material of lower refractive index. The fibres whose light (6) is to be tapped is connected to a section of optical fibre having alternating curves which induce a succession of mode transportation in the light propagating in the core of the fibres. There are sufficient mode changes to ensure that the final value of the propagation constant is below the lower limit for propagation in the core. Thus the light whose propagation contact has been reduced, propagates in the surrounding material.
