Patent DE-3130736-A1 (DE)
Title: Circuit arrangement for measuring low thermal powers
Inventor: DANIELMEYER HANS GUENTER PROF
IPC: G01N25/48
Filed: 1981-08-04
Abstract: An electronic calorimeter is intended to permit efficiencies, flow rates and thermal conductivities to be determined by measuring low thermal powers. According to Fig. 1, a temperature-dependent resistor (11), (e.g. PTC resistor) is situated in a bridge circuit and is heated up by the bridge current. By controlling the bridge current, a controller (16) keeps the bridge in balance and thus maintains the temperature of the PTC resistor (11) constant via the ambient temperature. The electric power converted in the process in the PTC resistor (11) is determined in a multiplier (18) by current and voltage measurement (I, U). When the PTC resistor (11) is brought into thermal contact with a heat source or heat sink (12), this converted electric power (P) varies precisely by the value of the thermal power absorbed or released, i.e. the thermal power is compensated for by an electric power if measurement is made in each case in equilibrium (in the steady state). The compensated thermal power can be used to measure efficiencies or quantum efficiencies of opto-electronic and Peltier components as well as of laser crystals, or else thermal conductivities and flow rates of fluids. <IMAGE>

Patent DE-3220159-A1 (DE)
Title: Two-for-one twisting spindle
Inventor: REHN KARL-HEINZ
IPC: D01H7/86
Filed: 1982-05-28
Abstract: The feed-bobbin carrier (3) of a two-for-one twisting spindle possesses an additional rotation-preventing device besides the magnetic retaining device consisting of an inner and an outer magnet (4 and 5). The main element of this rotation-preventing device is a stop body which consists of a stay (10) and of a bolt (11) connected to the latter at an angle. The stop body (10, 11) is inserted in a pocket-like recess (8) of the feed-bobbin carrier (3). The recess (8) has on its bottom a concave spherical or cylindrical curve (9), in which the stay (10) is supported with its correspondingly convexly or cylindrically rounded foot, in such a way that the centre of gravity of the stop body (10, 11) is between the support point (1) and the axis of rotation of the feed-bobbin carrier (3) in the position of rest of the feed-bobbin carrier (3). The above-described design of the curve (9) and stay (10) avoids the need for an articulation suspension of the stop body (10, 11) by means of a pivot pin or bearing pin. Should the feed-bobbin carrier (3) be set in rotational movement in spite of the magnetic retaining device (4, 5), the stop body (10, 11) tilts on the rounded supporting foot under the effect of centrifugal force, in such a way that the bolt (11) comes out of the circumferential orifice (12) of the feed-bobbin carrier (3) and butts against a fixed machine part. <IMAGE>

Patent DE-3302441-A1 (DE)
Title: Process for the operation of a heat pump
Inventor: HORNUNG ALFRED DIPL ING
IPC: F25D21/12
Filed: 1983-01-26
Abstract: In the process, the state of icing of the evaporator is determined by a sensor, and the evaporation of the refrigerant is interrupted during defrosting of the evaporator. When the evaporator ices up at an air temperature above 0 DEG C, it is defrosted solely or principally by ambient energy, an air-delivery device associated with the evaporator being switched over into an operating state with a greater delivery volume. Defrosting can thus be accomplished by simple means, while conserving energy, without the heating operation being interrupted for too long by the defrosting phases.

Title: Valve for gaseous or liquid media
Inventor: TRACHTE DIETRICH DIPL ING
IPC: F02M51/06
Filed: 1983-09-12
Abstract: The invention relates to a valve which is, for example, driven electromagnetically and the movement of the valve member of which is influenced by means of a permanent magnet. For at least one of the end positions of its valve member, the valve has stop faces between the valve member and the housing, which faces can be crossed by the magnetic circuit of the permanent magnet, with the result that, when the faces are resting against one another, an optimum retention force, dependent on the force of the permanent magnet, is obtained. Upon actuation of the valve member out of this stop position, this force of the permanent magnet must be overcome, leading to a gain in acceleration work. In addition, rebounds, which would result in at least a brief separation of the faces, are prevented upon impact of the stop faces. <IMAGE>

Title: Process and equipment for thermally treating coarse-grained and/or lumpy materials
Inventor: RODENHAEUSER FRITZ DR
IPC: B01J6/00
Filed: 1983-09-24
Abstract: In hitherto known processes and equipment for thermally treating coarse-grained and/or lumpy materials, in particular for burning limestone, dolomite, magnesite or the like, in a shaft furnace, the fuels, in particular also inferior fuels, have been burned in the shaft furnace itself. In this case, however, it cannot be avoided that the pollutants present in the fuel precipitate on the coarse-grained and/or lumpy materials and thereby considerably impair the quality of the finish-burned material. According to the invention, however, this is avoided by burning inferior fuels in a combustion chamber (2, 14) outside the shaft furnace (1, 15) and feeding the combustion gases to the shaft furnace (1, 15) for burning the coarse-grain and/or lumpy materials. <IMAGE>
