Patent DE-4323871-A1 (DE)
Title: Method and device for forwarding messages received on an answering device
Inventor: SCHELLHAAS WERNER
IPC: H04M1/658
Filed: 1993-07-16
Abstract: When an answering device is interrogated for received messages, the callers often indicate callback numbers on which they would like to be called back urgently by the called party when a one-way left message is deemed to be inadequate. On interrogation, and in particular on remote interrogation, these callback numbers are often difficult to understand and first need to be noted down. In the method according to the invention, the caller is prompted to enter his callback number in the form of DTMF signals. These are stored along with the message in the answering device and, when the "forward" facility is activated, the answering device transmits the string of digits with the call message to the pager, so that the called party, even when en route, can dial the callback number without interrogating his answering machine. The invention is suitable for all answering devices with a forwarding facility which can receive and store DTMF signals. <IMAGE>

Title: Process for the mfr. of columnar concrete blocks with profiled surfaces
Inventor: MUENCH HANS-JOSEF
IPC: B28D1/30
Filed: 1994-03-23

The weak concrete splits at the groove to leave a block of the correct size with a profiled surface and pleasing bevelled edges.
Patent DE-4411437-A1 (DE)
Title: Axial piston compressor with turning valve
Inventor: KIMURA KAZUYA
IPC: F04B39/10
Filed: 1994-03-31
Abstract: The invention relates to an axial piston compressor having a plurality of pistons which, by means of a swash plate arrangement or the like, can be driven into reciprocal motion in bores of a cylinder block. A turning valve is arranged in a cylindrical chamber of the cylinder block and is linked, in a torsion-proof manner, to a drive shaft of the compressor. The turning valve serves to open and close radical ducts, provided in the cylinder block, between the cylindrical chamber and the individual cylinder bores. A leakage flow of the fluid to be compressed, which flow escapes from those cylinder bores in which a compression stroke is taking place at the time and which flows into the gap between the lateral surface of the turning valve and the inner surface of the cylindrical chamber, is collected according to the invention by means of groove-shaped duct devices which form a closed loop in the lateral surface of the turning valve, in order to prevent any ingress of leakage gas into the swash plate chamber.

The separate wires run around the bellows opening in opposite directions, joining the second conductor. If there are several conductors, they are electrically in series.
Patent DE-4418844-A1 (DE)
Title: Two stroke IC engine
Inventor: KOTTMANN HELMUT
IPC: F02B33/44
Filed: 1994-05-30
Abstract: The invention concerns a two-stroke internal-combustion engine with a charging pump, an outlet channel (18) controlled by the main piston (3) being subjected to additional control by the charging-pump plunger (4). Circulation losses are minimized and a higher mean working pressure is obtained by early mechanical closure of the outlet channel (18) by means of the charging-pump plunger (4) or by injecting a pulse of exhaust gases into the outlet channel (18) in the direction opposite to the direction of flow or by injecting part of the intake charge through the outlet channel (18) into the main cylinder (1). In addition, the formation of oxides of nitrogen is reduced by controlled exhaust-gas retention at the combustion stage. The invention also allows a catalytic converter to be used if required, since an increase in the oxygen concentration owing to circulation losses in the outlet channel is avoided.

Patent DE-4423351-A1 (DE)
Title: DC=AC converter using electromagnetic induction principle
IPC: H02M3/335
Filed: 1994-07-04
Abstract: A device uses the principle of electromagnetic induction to convert electrical energy from DC to AC or from DC to DC. An electronically controlled switch is used to govern the charging of a capacitor from a voltage source through one section of a tapped transformer primary winding, followed by discharge through another section in the reverse winding direction. Alternatively, the whole primary winding may be used for charging and discharging, again the directions being opposite. This provides the basic of an alternating magnetic field, used to induce an alternating voltage in a secondary winding which may subsequently be rectified if needed.

Title: Method and device for the controlled heat exchange between a primary steam circuit and heat consumer
Inventor: BAELZ HELMUT
IPC: F01K19/08
Filed: 1981-09-21
Abstract: In a heat consumer (2), of which the supply conduit (12) is under a predetermined pressure and of which the return (13) is at a lower pressure, the steam, drawn off from the primary steam circuit in relation to the heat used by the consumer, is cooled down until condensation by drawing off heat by means of a secondary fluid and by maintaining a certain overpressure with respect to the pressure prevailing in the supply conduit (12). This overpressure is reduced to the pressure of the supply conduit (12) by means of a jet pump which allows a drive force to be obtained for the supply conduit (12) and the addition to the supply conduit heated secondary fluid obtained by the cooling of steam. In order to avoid installing an overpressure pump upstream of the jet pump while eliminating superfluous valves and connections, the condensate is accumulated to set the heat consumer temperature and the accumulation of condensate is exclusively set by adjusting the ejection nozzle (10).

Abstract: Dans des installations de génération de vapeur au moyen de chaleur perdue, il s'agit d'utiliser de la manière la plus efficace possible la chaleur des gaz chauds d'échappement qui traversent le générateur de vapeur (5). A cet effet, l'eau d'alimentation se partage en deux courants dont l'un mène aux surfaces de chauffage (23, 24, 25, 28) de l'évaporateur sous haute pression et l'autre aux surfaces de chauffage (32, 33) de l'évaporateur sous pression moyenne. Le partage entre les deux courants est réglé en fonction de la qualité de la vapeur que l'on veut obtenir, de sorte que la vapeur dans les surfaces de chauffage du surchauffeur intermédiaire est chauffée jusqu'au même niveau de température que la vapeur dans les surfaces de chauffage du surchauffeur à haute pression. L'invention peut s'appliquer notamment dans des centrales électriques à turbines à gaz et à vapeur (centrales composites).
