Patent DE-2627859-A1 (DE)
Title: Cutting or machining using an electric arc - where vibrating electrode is also used for mechanical removal of molten material
Inventor: BALS HANS GUENTER DIPL ING
IPC: B23K9/013
Filed: 1976-06-22
Abstract: The parent patent describes the cutting or machining of electrically conducting materials using an arc obtd. by applying an alternating current (a.c.) to the material and to an endless rotating electrode. The electrode is vibrated in the direction of cutting, and, during its forward stroke, the voltage is switched off and the electrode used for the mechanical removal of molten material. The switching off of the voltage is improved by the natural passage of the a.c. through zero. The vibration of the electrode is pref. obtd. by using a synchronous motor. Large cost outlay in a small plant is avoided.

Title: Bowed or plucked, stringed musical instrument - has strings passing over bridge attached to apex of cone-shaped sound emitting diaphragm
Inventor: HASS WALTER DIPL ING
IPC: G10D3/02
Filed: 1976-06-28
Abstract: The stringed instrument may be placed by bowing, plucking, pulling, or hitting the strings. The mechanical-acoustic components of the sound radiator and largely also of the bridge, were built up of separate structural spatially separated elements. The instrument is altered to obtain symmetrical vibrations of the strings and provision to control the frequency characteristics of vibrations. The fulcrum of the bridge turning about an axis parallel to the strings is determined as the point of intersection of the bridge with the line of the stretched strings and an imaginary line through it passing through the pivoting point of the string support.
Patent DE-2632693-A1 (DE)
Inventor: PFENNIG EGBERT
IPC: A24B15/28
Filed: 1976-07-21
Abstract: The aim is to reduce the amounts of condensate precipitating from tobacco smoke. It has been established that the aldehydes and ketones contained in the smoke show disadvantageous physiological effects, in that they paralyse the cilia of the windpipe, as a result of which a feeling of dryness arises. These smoke constituents are derived in particular from the cellulose constituents of the tobacco material. Attempts are being made to reduce these disadvantages without having to accept significant influence of the tobacco components responsible for the smoke flavour and of the nicotine content. This is possible by the tobacco leaf material containing tobacco ribs impregnated with aqueous alkali metal carbonate solutions and dried to normal production moisture.
Patent DE-2634772-A1 (DE)
Title: Fluid driven rotary brush with increased operating efficiency - uses pelton wheel and nozzle inflow duct to overcome low water supply
IPC: A46B13/06
Filed: 1976-08-03
Abstract: The rotary brush is operated by a fluid drive means wherein a paddle wheel designed as a Pelton wheel (8) is rotatably mounted in a housing and is connected by an axle to a plate provided with bristle whilst the housing has a water inlet in the form of a nozzle duct (4) which is mounted level with the Pelton wheel (8) and pref. set tangentially to the blades (9). Using the Pelton wheel means that a max degree of efficiency is reached even with relatively small amounts of water and relatively low water pressure. This is also enhanced by the nozzle duct substantially increasing the rate of flow of the incoming fluid. The axis of the nozzle duct pref. coincides with that of the connecting pipe (3) for the supply pipe so as to avoid any pressure losses inside the fluid pipe.

Title: Heat exchanger for solar energy conversion - has flexible parts exposing reflecting zones to radiation on receiving excessive radiation
IPC: F24S10/50
Filed: 1977-01-22
Abstract: The heat exchanger is used for converting pref. solar radiation into thermal energy. The heat exchanger has adequate size for ensuring heating effect during periods of low radiation. However, overheating is prevented on excessive radiation. The heat exchanger or a secondary system change their shape under pressure change continuously or discontinuously. The change of shape varies the amount of incident radiation on heat exchanger surface. The heat exchanger has absorbing and reflecting zones. The absorbing zones are exposed to radiation in operating condition and reflecting surfaces are exposed to solar radiation when the system is pressurised.
