Title: Turning device of a slatted blind
Inventor: AMMAZZALORSO MARIO
IPC: E06B9/307
Filed: 1983-04-16
Abstract: The turning device, which forcibly pivots the slats of a gatherable slatted blind on every change of direction of rotation of the drive shaft, has a gear which converts the rotary movement of the shaft into a translation movement which is transmitted to the support members of the slats which, directed in the opposite direction, are deflected into the plane of the translation movement. Connected to rotating gear components are the coupling means which bring about releasably a rotationally fixed connection of the shaft to the device for transmission of its movement to the support members, while the release members for releasing this connection are in each case part of the translationally moved gear components. At the same time, the stops serving as release members can be displaceable on the translationally moved gear components, in order to effect the release of the rotationally fixed connection in different turning positions of the slats.

Title: Bottom for the tank of a tubular heat exchanger, and tool for producing it
Inventor: SCHENK KARL-HEINZ
IPC: F28F9/02
Filed: 1983-05-09
Abstract: The invention relates to a bottom for the tank of a tubular heat exchanger, in particular a connecting piece for accommodating the flat tube. The aim of the invention consists in specifying a cost-effective tank bottom. The object of the invention is to develop for subsequent soldering an optimum tank bottom having connecting pieces. The object is achieved according to the invention when the connecting pieces of the tank bottom each consist of two middle pieces (1.1) of rectangular cross-section in conjunction with an end face positioned obliquely inwards, and of the lower end pieces (1.3), and the profile transition (1.4) is marked on the outside of the connecting piece. As a result, the liquid solder can reach a maximum surface area during the joining process. The connecting piece has a crack-free, circumferential inner wall as a precondition for being soldered tight, and large-area support elements which are self-closed with respect to the tube to be connected and satisfy the high strength requirements placed on the soldered joint. <IMAGE>

Title: Control system for a heating or cooling plant
Inventor: TAAG JUERGEN
IPC: G05D23/20
Filed: 1983-06-21
Abstract: The present invention relates to a control system for a heating or cooling plant with a heat source and a heat exchanger coupled to it. The system has a measuring element for the external temperature and a reference value setting means for the room temperature. It also has a heating or cooling curve control in which a feed temperature is predetermined as a function of an external temperature and with a comparator to determine the switch-off and switch-on reference value for the heat source. The object of the present invention is to establish the point at which the heating plant is switched on again exclusively as a function of the relationship between the external temperature and the temperature of the rooms, so that the rooms heated by the heating or cooling plant cannot fall or rise overmuch below the external temperature value. This switching-on-again is to take place independently of the steepness of the heating or cooling curve which is set. The solution of the problem is achieved in that the switching reference value is determined by the difference between a room temperature reference value and the actual value of the external temperature, where this difference can also go towards zero.

Title: Shaped part of concrete, ceramic compounds or the like
Inventor: POETHMANN ROLF
IPC: E03F3/04
Filed: 1984-01-07
Abstract: A shaped part of concrete, in particular a concrete pipe, is proposed which on the inside contains a longitudinally running, channel-like passage which is defined by the inner surface of corresponding wall parts. In a special manner, the inner surface, at least in the area of a surface section which lies at the bottom when laid like a channel, has irregularly distributed prominences and/or recesses and/or wall apertures, which are also of irregular configuration in their dimensions, in the foot-side wall. The flow velocity of water flowing through is thereby substantially reduced. Plants, mosses or the like can establish themselves in a channel thus formed. Micro-organisms can also exist in such a channel and pass through it.
Patent DE-3400571-A1 (DE)
Title: Rotary engine
Inventor: MENZENBACH MARTIN ALFRED
IPC: F01C1/344
Filed: 1984-01-05
Abstract: Rotary engine for the direct conversion of heat energy into rotational energy, characterised in that a fuel-air mixture is drawn in through an inlet valve (6) into a circular, fixed housing (1) and thus enclosed in an evacuated chamber formed from eccentric shaft (2) and partition walls (3), and housing wall (1), ignition of the mixture occurring in a minimal volume - in a chamber configuration (I) - after a 180 degree rotation by contracted chamber and gas volume. After a 360 degree rotation an exhaust valve (4) opens and allows the major proportion of the old gases to escape at maximum gas volume. After a 540 degree rotation of the chamber, the old gases still contained in this are compressed and thereby expelled to the outside of the combustion chamber through a second exhaust valve (5) arranged offset in relation to the first. After a 720 degree rotation a vacuum can be built up by expansion of the chamber volume and fresh gas imploded into this again by opening of the inlet valve (6). The number of partition walls (3) must be an odd number greater than one. In the case of five partition walls therefore five fuel explosions occur for two revolutions of the eccentric shaft (2). <IMAGE>
