Title: Multichannel communications system with TDM - with speech and data transmission and synchronising by way of data channel
Inventor: SCHUMM ERWIN
IPC: H04J3/12
Filed: 1980-04-15
Abstract: The transmission system has a number of broad band channels (2-15), for example for speech transmission, and narrow bands (1'-16') for data signals. The latter are first applied to a sub-multiplexer (23), emerging as a single channel (16) to the main multiplexer (21) processing all the channels. The receiver end is similarly arranged. The synchronising channel carries an n-bit synchronising word in which the number of bits (n) is equal to the number of narrow band channels associated with the sub-multiplexers. With this arrangement each data channel is interrogated once in each cycle of the multiplexer scan. One particular bit in the synchronising word is associated with a specific data channel. The application of the multiplexer system is typically to mobile telecommunications systems.

Title: Rotatable multifaceted mirror in an optical system
Inventor: BEHRENS HERBERT
IPC: G02B5/09
Filed: 1981-02-25
Abstract: In an optical system, in particular in an optical chart recorder, a rotatable multifaceted mirror is used for raster-like recording of data on a light-sensitive recording carrier by means of a light beam which is modulated in accordance with the data to be written and can be deflected in the row direction over the recording carrier by means of the multifaceted mirror. The individual component mirrors (2) of the multifaceted mirror are arranged with an angular offset on a common, rotatable support (1). The production of such multifaceted mirrors is, however, very complicated, in order to prevent deflection errors in the individual component mirrors, depending on the application, either in the vertical direction (line height) or in the horizontal direction (line length). The component mirrors (2) are therefore mounted on the rotatable support (1) individually by means of adjustable mounts (9 to 11), as a result of which positional errors are individually compensated for each component mirror (2) in such a way that all the component mirrors (2) can be set for a precisely registered line movement, for a precise column position or for line heights of the light beam (8) on the recording carrier which are different but uniformly stepped. <IMAGE>

Patent DE-3148344-A1 (DE)
Inventor: BUEHNER ERNST
IPC: F27B9/38
Filed: 1981-12-07
Abstract: An automatic pig-charging apparatus for hot-chamber pressure-diecasting machines is described, which enable small parts to be manufactured e.g., a Zamak alloy especially under mass production conditions. Excessive fluctuations of the level of the liquid metal melt have prove to have disadvantageous effects on the quality of small parts, and on the service lives of the pressure-diecasting machines and dies. The aim must accordingly be to minimize the fluctuations. The present invention provides a control system, which keeps the liquid metal level within narrow limits. A float switch automatically triggers a charging operation whenever the lower liquid metal level is reached. This operation involves the automatic replenishment of the liquid metal melt by addition of pigs supplied from a replenishing station.

Title: Conveyor band having an intermittent drive
Inventor: FELDKAEMPER RICHARD
IPC: B65G43/08
Filed: 1982-04-22
Abstract: A conveyor band having an intermittent drive, preferably for the storage of bundles of flat material, such as hose portions or the like, consists of a first conveyor band which feeds the bundles and which is followed by a second conveyor band designed as a storage conveyor band and by a conveyor device leading the bundles away. Located in front of the first bundle lying on the second conveyor band is a light barrier which, after the drive has been switched on, upon the detection of the leading edge of the bundle, starts an electronic timer which stops the drive after the expiry of the time corresponding to the passage of a bundle. So that the storage conveyor band can be filled up automatically again after the last bundle has been discharged from it, at the same time as the first electronic timer a second electronic timer is started and is stopped again after the expiry of the time corresponding to the passage of a bundle. The second electronic timer measures the discharge time of all the bundles lying on the second conveyor band in a summing manner and, after the expiry of the total time corresponding to the discharge of all the bundles, switches on the drives of the conveyor bands for filling the second conveyor band. After the leading edge of the first bundle has been detected by the light barrier sensing the front end of the storage zone formed by the second conveyor band, the drives are stopped again. When they are stopped, the second timer is reset.

Patent DE-3224482-A1 (DE)
Inventor: BEKIAROGLOU PRODROMOS PROF DR
IPC: F02B75/26
Filed: 1982-06-30
Abstract: PCT No. PCT/EP82/00213 Sec. 371 Date May 18, 1983 Sec. 102(e) Date May 18, 1983 PCT Filed Sep. 23, 1982 PCT Pub. No. WO83/01088 PCT Pub. Date Mar. 31, 1983.This invention refers to a piston machine, most particularly an internal-combustion machine, in which the cylinder wall performs a rotating motion round its own axis. Apertures on the cylinder wall allow it to act as a rotating slide valve, so that no valve system is needed. In the first example, the stroke movement of the piston is converted to the rotating motion of the cylinder wall (which on the same time serves as the axle of the machine) through bolts which slide or roll in linear guide-slits in the cylinder wall and curved guide-tracks on the stationary outer part of the machine. The use of the curved guide-tracks allows the adaptation of the time-law for the volume change in the working chamber, to the needs of the mechanics, thermodynamics and reaction kinetics. In the same rotating cylinder are installed two pistons of equal mass which fulfil an exactly symmetrical opposite motion, so that no free accelerating forces exist and therefore no vibrations appear on the machine. In the second example the stroke movement of the piston is converted to the rotating motion of the axle through a crank and two universal joints. The relative position of the axis of the crank and the axis of the cylinder determine the length of the stroke and in consequence its power. The crank's bearing position can vary correspondingly to the cylinder during the function of the machine, so that its power is continuously variable and even its working direction can be reversed without stopping and by constant rotating speed.

Title: Double strand filters for fuel oil burners
Inventor: GOTTFRIED JOSEF DIPL ING
IPC: F23K5/18
Filed: 1982-07-26
Abstract: Double strand filters for fuel oil burners, which in the hitherto known embodiment could only be shut off by hand in the outlet duct, while the return duct was automatically shut off by a non-return valve, are provided with a double shut-off device to be actuated manually, such that the valve seals of two adjacent valve trains (4 and 16) arranged on a filter plate (1) are connected together through their guide rods (14 and 29) by an actuating bridge (12). The function of the automatically operating non-return valve is maintained by the non-return valve cone (9) being mounted separately and freely movable in the guide rod. The additional function of a safety valve is achieved, in the closed state and when the nominal pressure is exceeded, by the spring-loaded guide rod, at whose ends the valve seals are arranged, so that the excess pressure which exists for a short time, possibly due to the running-on of the fuel oil pump, is conducted away into the return flow duct, and an excess pressure arising in the flow duct because of the thermal expansion of the fuel oil is taken up in a volume reservoir which results from raising the guide rod (14) into the spring space (15). <IMAGE>
