Title: Hot-air ducting device for radiators
Inventor: PLUEMER KARL-HEINZ
IPC: F24D19/06
Filed: 1983-01-29
Abstract: The invention relates to a hot-air ducting device (1, 7), which is arranged between the radiator (14) and the wall (15). The hot-air ducting device comprises a flat hollow duct housing 1, the width of which corresponds approximately to the width of the radiator and which is open at the top and bottom. At the upper end their adjoins a deflecting baffle (7). The air heated in the duct housing rises upwards and is deflected away by the deflecting baffle towards the interior of the room. Heating of the inside of the wall (5) or of the window (17) is reduced by the hot-air ducting device, whereby the heat lost through the wall or the window is also reduced. <IMAGE>

Title: Ceramic internal combustion engine without piston lubrication
Inventor: STRACH LOTHAR
IPC: F02B75/32
Filed: 1983-02-01
Abstract: In reciprocating piston internal combustion engines the facility fundamentally exists for reducing the specific fuel consumption by reducing the heat dissipation of the components forming the combustion chamber by using high-temperature-resistant ceramic parts in place of existing cast iron or light alloy parts. If use is made of operating limit data in the case of ceramic parts a surface temperature of the inside cylinder is produced in an order of magnitude where the hitherto usual lubrication between piston and cylinder wall is no longer possible. For this reason according to the invention a reciprocating piston is carried in a straight line in a cylinder so that no contact occurs with the cylinder and hence no lubrication is necessary. The passage of gas through the resulting annular gap is reduced by means of a contraction due to a counter-flow, produced by means of a sharp edge on the piston head.

Patent DE-3325993-A1 (DE)
Title: Regulating and control method for operating a heating system and a regulating and control device for carrying out the method
Inventor: MAAG WERNER DIPL PHYS
IPC: F24D19/10
Filed: 1983-07-19
Abstract: The temperature regulating unit of a heating system (H) is combined with a cascade circuit (22, 25, 39), operating in stages and as a function of load, for switching a plurality of heat generators (1a, 1b, K) on and off. It is suitable for multi-stage heat-pump operation (1a, 1b) in a bivalent heating system having a boiler (K) for fossil fuels as auxiliary heat generator. An integrator (18) integrates a temperature difference ( DELTA  theta ) between a desired and an actual value ( theta vs,  theta vj) with respect to time (t). A first threshold value switch (23) influenced by the integral regulates in each case one of the heat generators (1a, 1b, K), as a function of the heat requirement, in on/off operation, or an actuator (6, 7) in a quasi-continuous fashion as a pulse generator (24). Via a second threshold value switch (22) with a higher threshold value, the same integral controls the load-dependent switching on and off of the heat generators. The regulation and control system is suitable for low-temperature heating installations with flat heating curves, and also prevents the short-term switching on and off of the regulated heat generators (1a, 1b, K) under limiting conditions.

Title: Photographic camera with electronic exposure control and built-in electronic flash unit
Inventor: BAUMEISTER HANS-PETER
IPC: G03B15/05
Filed: 1983-08-10
Abstract: A description is given of a circuit arrangement for a photographic camera with a built-in electronic flash unit and electronic exposure control, which for reasons of space is operated with only two batteries together having a nominal voltage of 3 V. This voltage is not sufficient to supply the electronic exposure control with an adequate voltage, in particular if the voltage further drops considerably due to loading during operation of the flash unit. Consequently, the voltage transformer 1 of the flash unit is used to charge a capacitor C1 which is connected in series to the battery B, as a result of which a higher voltage is available in this series circuit for supplying power to the electronic exposure control 2. <IMAGE>

Title: Circuit arrangement for a power feeding device
Inventor: SCHLAGENHAFT JOHANN
IPC: H04B3/44
Filed: 1983-08-12
Abstract: Known arrangements which are intended to maintain the power feeding of intermediate stations of a telecommunications device at least partially even after a break in the power feed loop, contain as an essential component a relay having a changeover contact and two part windings. The part windings are located in the power feed loop, so that in the event of failure of the supply current the relay drops out and its changeover contact sets up a cross connection between two wires of the power feed loop. Since the failure of the feed current due to a break in the power feed loop is a rare event, the relay is almost always operated in a circuit state in which the armature touches the terminals on the working side of the changeover contact. Because of the long service life, the high reliability, the high input and output situation, the constant contact resistance, the stable time response and the insensitivity with respect to overloading, it is preferable to use mercury contact relays. However, chemical changes on the contact surfaces can lead precisely in these relays to sticking of the armature in the specified circuit state, so that the relay does not change its circuit state after failure of the feed current. In the proposed arrangement, the relay contains a back contact with two terminals. This special configuration of the relay ensures drop out even if the excitation firstly ...

Patent DE-3337722-A1 (DE)
Title: Housing front frame for television receivers
Inventor: KOHLER JOHANN
IPC: H04N5/64
Filed: 1983-10-18
Abstract: The housing front frame according to the invention consists of two separate frame parts, namely an asymmetric part as is usually used for television receivers with single-channel sound transmission, and an additional frame part for a second operating and loudspeaker panel. The two parts are either connected by means of a separate clamping rail or are themselves provided with rearwardly open U-profile edges which allow a direct form-locked connection. The form-locking of the clamping connection is preferably improved further over the entire length by the fact that the clamping rail or the U-profile edges are provided with a number of holes at the level of the transverse ribs used for stiffening the frame. The front frame construction according to the invention overall requires fewer tools for television receiver types with single-channel sound transmission and those of the same screen size with stereo sound transmission, since only one main frame and a considerably smaller additional part are needed. Further advantages lie in the greater flexibility in the type and quantity planning for receivers with mono and stereo sound transmission and in the stockkeeping for the frame parts.

Filed: 1983-12-14
Abstract: Method for increasing the power rise with increasing generator rotation speed in electrical systems which are to be newly installed or exist and are supplied from power-generator machines having rotating components which are intended to carry out electrical work at various rotation speeds. An approximately constant power consumption in the load resistors is achieved, without a controller being required for a power setting, with a constant energising field and over a widely varying rotation speed range, by the series connection of suitable capacitors to the load resistors in the individual circuits of the generator. In particular, the rated power is achieved at a considerably lower rotation speed in comparison with the circuit without additional capacitors.

Abstract: Application P 3411379.7 discloses a steam power plant under the roof tiles, which is operated by the heat of the sun. Added thereto as fundamentally new: the liquid for evaporation must have a low boiling point. This must have a favourable difference from the temperature which is reached by the roof tiles as a result of the solar radiation. This difference is to be selected to be as great as possible for optimum current generation. The height of the liquid level of the evaporator liquid must be adapted according to the temperature of the roof tiles and the boiling point of the evaporator liquid; on warm nights and dull days, erected metal surfaces absorb the heat of the air. The arrangement of these metal surfaces is to be such that this absorbed heat is supplied to the evaporation of the evaporator liquid. For optimum current generation, that one of a number of evaporator liquids is pumped into the tubes, which, according to the temperature of the roof tiles, promises the most favourable current delivery. The current generated can be used for pumping the residual heat of the remaining solar collector surfaces into the heat block, see the patent case "Heat block as energy store for vehicles and technical purposes". Oven heat can also be used for evaporation in an emergency. Car drive: In the patent case "Heat block as energy store for vehicles and technical purposes", it is shown how vehicles ...

Filed: 1984-09-04
Abstract: There is disclosed a logic signal multiplier circuit which includes the interconnection of a plurality of inverters having outputs interconnected by a capacitor. Each of the inverters includes complementary transistors having their gates connected to a common terminal such that each inverter may be controlled by a separate clock control signal. The control signals are coupled to provide a three-phase operation of the circuit which insures (1) charging of the capacitor between the outputs of the inverters during a first time period, (2) an increase of the voltage at a node of one of the inverters to a value which is twice the value of the supply voltage driving the inverters during a second time period, and (3) coupling of that same node to ground during a third time period. Diodes are interconnected in each of the inverter circuits to prevent discharge of the capacitor during times that selected ones of the transistors forming the inverter circuits are conductive.
