Patent DE-2418660-A1 (DE)
Title: Mechanism for deriving energy from slow streams OF WATER - has submerged belt system with collapsible driving vanes
Inventor: BESSER FRITZ
IPC: F03B17/06
Filed: 1974-04-18
Abstract: Energy is derived from flowing bodies of water by means of resistance bodies which are moved by flowing water. This arrangement is also able to conver the energy of slowly flowing waters and the mechanism is fully concealed under water and under ice and hence their presence is not as noticeable as that of waterwheels or turbines. The mechanism consists of pulleys held at the ends of the support member paralle to the water surface. An endless belt with collapsible vanes is rotated over these pulleys by the water flow. The vanes on the lower part of the belt are extended and they are driven by the water flow. These vanes lie flat on the upper part of the belt. Below the lower, extended, vanes is arranged a parallel support with guide vanes. This arrangement can be used in tidal waters.

Title: Castor for seating furniture - has leaf spring brake band to provide anti-rolling friction and post exclusion
Inventor: KUHN GUENTER ING GRAD
IPC: B60B33/02
Filed: 1974-04-20
Abstract: The castor rolling surface is fitted to a rotating shaft which has a moulded braking surface of a cylindrical shape. A shaped leaf spring braking band is clipped to the castor support and presses against the braking surface to impart a steady friction force to the castor. The brake is thus sealed against dirt and dust and is not affected by castor wear. It is self adjusting under the weight of the castor load and is simple and economic to fit. When the spring load is pushed from the castor by a person sitting on the chair, the unit is released for rolling, but does not move upon the occupant standing up.

Title: Depositing metals by spraying - where template mask is vibrated to prevent deposn. on the template
Inventor: SCHULTE AXEL DIPL ING
IPC: C23C4/01
Filed: 1974-04-24
Abstract: In a device for the coating or workpieces by spraying them with molten metal using a holder for the substrate, the substrate holder is subjected to vibration in the region of the spray, the vibration contg. a component lying in the same direction as the spray. The vibration pref. has a frequency in the region of a few hundred hertz and an amplitude of some microns. Pref. an electromagnet is used to vibrate a template-mask which acts as an armature and also as a vibratory conveyor, the mask forming part of the substrate holder. Used e.g. for depositing metal by spraying to form contact surfaces on resistors used in surge arresters, or covering electrodes for selenium rectifiers. The device prevents the metal spray from depositing on the substrate holder, esp. on the edges of the mask, and therefore eliminates the necessity for periodic mask cleaning.

Title: Road construction by coating frost-protective layer - with heat-insulating vibration-damping phase-displacing hydraulically bonded layer
IPC: E01C7/10
Filed: 1974-05-13
Abstract: Gravel/crushed rock frost-protective layer of roadway construction is covered by hydraulically bonded road-forming layers, prepd. by using materials of vitreous-amorphous phase of system CaO, SiO2, Al2O3, Portland cement or another binder-former of alkaline or sulphate nature. Bulk wt., strength and elasticity of layers decrease downwards, whereas insulating activity increases downwards. Layers have a heat-insulating, vibration-damping and phase-displacing activity. The covering layers are suitable for all traffic routes, e.g. roads, motorways and landing strips, and also rail-road top structures. They combine strength, elasticity, heat-insulation and heat-storage, allowing a reduction in thickness of frost-protective layer.

Title: Single lens mirror reflex camera with automatic exposure control - has two photoelectric transducers for internal and external light measurement
Inventor: ELKE DIETMAR DIPL PHYS DR
IPC: G03B7/08
Filed: 1975-08-13
Abstract: The first transducer is in the light path of the objective and the second outside the objective. Exposure control is based on the signal from the second transducer, and the first transducer corrects the error due to the difference between the two measurements.

Title: Tubular rivets for core laminations - are deformed by internal pressure into perfect fit with sharp cornered rivet holes
Inventor: VOLKRODT WOLFGANG DR ING
IPC: H02K1/16
Filed: 1975-11-26
Abstract: Tubular rivets pass through all the laminations (4) of the core. Their holes (2) have sharp corners, e.g. hexagonal or clover leaf in form. The rivets (3) are tubular and initially not a close fit.
