Title: Radiant heating system
Inventor: JUNG SIEGFRIED
IPC: F24D3/12
Filed: 1982-05-11
Abstract: In radiant heating systems the heat is delivered to the space by the heated, surrounding space surfaces. If a long, uniform and mild heat delivery is required, the materials hitherto used have severe disadvantages. To reduce the high constructional costs and the costs for the heating plant, in a radiant heating system with floor, middle and ceiling layers, the middle layer is made of prefabricated panels of a wood material. The middle layer consists of prefabricated panels which can be fitted together by positive connections to form the middle layer.

Title: Formation method for positive and negative electrodes consisting of strip material for electrical rechargeable batteries
Inventor: CHRISTL HERIBERT DIPL ING DR
IPC: H01M4/22
Filed: 1982-12-17
Abstract: An electrode strip (1) which extends through two halves (which are electrically insulated from one another by means of a plastic block (3) but are intrinsically electrically conductive) of an electrolytic trough (2) is polarized by the current flow on side B in the reverse direction to that on side A during connection of the electrical power connections (5 and 6) to the terminals of a DC source, that is to say it is simultaneous charged and discharged in sections and as a function of current direction. A new continuous formation method for impregnated electrode strips is based on this principle, in the case of which charging and discharging of a formation cycle take place simultaneously and no longer successively in time, which is highly advantageous for the continuous production process of the strips in modern production lines. <IMAGE>

Abstract: In the seating furniture, the cushion for the seat (2) is arranged on a carriage (5) which can be pulled forwards and the backrest (3) is mounted on a displaceable bearing block (12) so that it can be tilted about a horizontal axis (10). A stationary head part (4) is provided whose cushion lies on the same level as the cushion for the seat (2). The seat carriage (5) is connected to the backrest (3) in an articulated manner, and said backrest is connected to the head part (4) in an articulated manner. As a result, the seat carriage (5) and the bearing block (12) together with the backrest (3) undergo a coupled relative movement relative to one another when pulled apart, such that the backrest (3) can be pivoted about an axis (10) which lies with spacing from its lower longitudinal edge. This provides the prerequisite for the fact that the backrest (3), which constitutes the central part of the cushion intended for bearing the trunk when the furniture is used as a bed, can correspondingly be kept in a horizontal or upright position. The division of the lying surface is arranged in such a way that the backrest (3) forms the main lying surface which supports the trunk of the body, while the surface interruptions between the backrest (3) and the seat (2) and between the backrest (3) and the head part (4) come to rest in the region of the backs of the knees and in the region of the head respectively. <IMAGE>

Patent DE-3330747-A1 (DE)
Title: Vertically radiating loudspeaker for stereophonic sound acoustic irradiation in large rooms
Inventor: LANG HANS-JUERGEN
IPC: H04R1/34
Filed: 1983-08-26
Abstract: The invention of a vertically radiating loudspeaker is based on the object of using a single commercially available broadband loudspeaker system in conjunction with the pyramid-shaped loudspeaker housing given by the radiation of the sound waves vertically upwards and downwards to ensure pleasant acoustic irradiation which is still tolerable even at high volumes. Due to the sound waves reflecting from the ceiling (or reflector) in combination with the vertically downwardly radiated low frequencies, caused by the design of the housing, consequently a very pleasant stereophonic sound with great voluminous richness of tone is obtained. The vertical radiation of the sound waves consequently eliminates the sharpness of conventional horizontal radiation at high volumes.

Title: Axial fan
Inventor: UFER HARTWIN DR
IPC: F04D29/32
Filed: 1984-07-11
Abstract: In the case of an axial fan, preferably a diffuser-less low-pressure fan for conveying cooling air in cooling towers and finned-tube radiators, having vanes arranged on a hub and having a small hub ratio, provision is made for the hub to comprise two disc-shaped bodies having unequal external diameters, of which the first disc on the inflow side has a smaller diameter than the second disc on the outflow side, and the vanes on their inflow sides have nose-shaped regions which, across the external diameter of the large disc, point inwards to the rotor shaft. Axial fans of this type, with respect to their flow behaviour, come close to the low losses of axial fans having an inflow cowl, more cost-effective manufacture being possible at the same time.
