Patent DE-3305838-A1 (DE)
Title: Radiant energy converter
Inventor: SOERGEL FRITZ-PETER DIPL ING
IPC: F24S10/75
Filed: 1983-02-19
Abstract: The invention concerns improvements to radiant energy converters in the form of solar collectors or solar absorbers and the like. In order to increase their efficiency, it is proposed according to the invention to use a heat carrier medium conducted in channels as a dark, if necessary coloured, liquid or gas and to make the channel walls transparent. In this manner, passage of the radiant energy of the sun through the channel wall is obtained without noticeable absorption, and the dark heat carrier medium is more intensively heated. At the same time a substantially smaller heat loss results, compared with known plants. <IMAGE>

Title: Method for the operation of an internal combustion engine and internal combustion engine for implementing the method
Inventor: SCHATZ OSKAR DR ING
IPC: F02B37/00
Filed: 1983-05-18
Abstract: A method for the operation of an internal combustion engine with exhaust supercharger which, if the exhaust gas energy lies below the required supercharger energy, derives mechanical energy from the output shaft of the internal combustion engine, and delivers exhaust gas energy to the output shaft of the internal combustion engine when the amount of exhaust gas energy exceeds the required supercharger energy. For implementing the method, the exhaust supercharger has an exhaust chamber and a charge air chamber separated from this by a movable partition wall, both chambers being provided with inlets and outlets for the respectively assigned medium and the exhaust inlet being equipped with a device for pulsed admission of exhaust gas. The partition wall is connected to the output shaft of the internal combustion engine by way of a power transmission device suitable for the transmission of power in both directions. In the event of insufficient demand for supercharger energy the charge air side is preferably rendered inoperative and pressureless.
Patent DE-3318385-A1 (DE)
Title: Wind power catcher for generating a rotary force
Inventor: MUELLER HEINRICH
IPC: F03D3/06
Filed: 1983-05-20
Abstract: In a wind power catcher according to the invention sails for catching the power are provided on the projecting ends of the legs of a crosspiece on the shaft to be driven. On the end of each projecting leg an upright sail with an upright edge on a sail mast is mounted so that it can pivot about a limited angle on a head piece, offset in relation to the crosspiece. The bottom edge of the sail at the same time forms a propulsion angle with the axis of the crosspiece. When the one side of the sail is acted upon by the wind, the device rotates clockwise about the shaft to be driven, the sail coming into a position in the same direction as the wind. If this position is exceeded, the wind begins to act on the other side of the sail as propulsion side, so that the sail swivels by the amount of swivel or swivel play and the other side of the sail is acted upon. The turning of the crosspiece and hence of the shaft to be driven is continued until the sail has adopted a position lying in the direction of the wind and further rotation causes turning over or swivelling of the sail by the amount of swivel play so that the other or first side of the sail is again acted upon and the sail returns into the initial position. The process begins again. Crosspieces arranged in a cross or more crosspieces can be provided with sails. <IMAGE>

Patent DE-3323195-A1 (DE)
Title: Sliding guide with ball bearings for drawers or tray bottoms
Inventor: POETTKER NORBERT
IPC: A47B88/14
Filed: 1983-06-28
Abstract: The invention relates to a sliding guide with ball bearings for drawers or tray bottoms, which sliding guide consists mainly of two profiled rails inserted one inside the other. The two profiled rails are of U-shaped construction in cross-section. In the outer profiled rail, the free ends of the limbs are bent inwards and, in the inner profiled rail, the free ends of the limbs are bent outwards. One bent end of the limb of the inner profiled rail and one bent end of the limb of the outer profiled rail in each case form the running grooves for a row of balls. Furthermore, the web of the inner profiled rail has a longitudinal outer groove and the web of the outer profiled rail has a longitudinal inner groove, which grooves, in turn, form the running grooves for a row of balls.

Title: Process for the gentle ozone treatment of liquids, such as fruit juices, milk, liquid milk products, wine, oils, liquid medicaments, blood and/or similar products
Inventor: SANDER MARTIN DIPL ING
IPC: A23L3/3409
Filed: 1983-07-15
Abstract: The invention relates to a process for the ozone treatment of liquids which are adversely affected in quality during conventional treatment with ozone gas for example via frits, injectors, dispersers and similar devices for treatment with gas bubbles. This applies in particular to fruit juices, milk, liquid milk products, wine, oils, liquid medicaments, blood and similar products.   Treatment of these by gas would either lead to undesired foam formation or, as a result of the gas feed in the form of bubbles, to an undesirable influence in composition or consistency. <IMAGE>

Patent DE-3340377-A1 (DE)
Title: Method for the transmission of information, in which the signals are coded by means of the magnitude of the amplitudes of the half- cycles or periods of a sinusoidal alternating current
Inventor: DIRR JOSEF ING GRAD
IPC: H04B14/02
Filed: 1983-11-08
Abstract: An unfavourable signal-to-noise ratio and a pulse-dependent frequency band expansion occur during pulse-amplitude modulation (PAM). High frequencies are required for the digital binary coding of signals using the half-cycles or periods of an alternating current and the characteristic states of low and high amplitude values. In the case of the invention, the samples taken from pulse-amplitude modulation of signals which extend from unipolar/binary to continuous are coded by means of the half-cycles or periods of an alternating current, and a plurality of alternating currents of lower frequency, having a predetermined mutual phase shift, are also provided for the taking of samples. The defects outlined above are avoided using these measures.

Patent DE-3409181-A1 (DE)
Title: Device for producing workpieces from pressed glass
Inventor: KOENIG WILHELM
IPC: C03B11/02
Filed: 1984-03-13
Abstract: In a device for producing workpieces, in particular hollow glasses, from pressed glass, the moulds arranged on the receptacles of a transport element are fed intermittently in succession to a stationary pressing station. At this pressing station, the pressing die present there, the mould and a cover ring sealing the top opening of this mould are centred with respect to one another, and specifically using a centring device which is provided at the pressing station and is common to the mould, the cover ring and the die. This achieves an extremely accurate coordination and centring of the moulding tool parts with respect to one another which is specifically independent of tolerances in the design and movement of the transport element as well as independent of tolerances which could result, for example, on account of thermal expansions at the moulding tool parts, at the transport element or at other parts of the device. <IMAGE>
