Patent DE-3539128-A1 (DE)
Title: Combustion chamber for diesel internal combustion engines
Inventor: RENGER UDO DIPL ING
IPC: F02B3/06
Filed: 1985-11-05
Abstract: The combustion chamber for diesel internal combustion engines has a main combustion chamber (4), formed in each cylinder between the piston head and the cylinder head (3), and a swirl chamber (5) which is arranged in the cylinder head (3) or piston (2), is connected to the main combustion chamber by a transfer port (8) and into which an injection nozzle (11) and possibly a glow plug (12) extend. In this arrangement, the transfer port (8) is to open into the swirl chamber in such a way that the air flowing in during the compression stroke is made to form a pronounced swirl flow (potential swirl) in the swirl chamber. In order to achieve especially favourable and low-noise combustion, it is proposed that the transfer port (8) and, in addition, also the injection nozzle (11) and the glow plug (12) open into the swirl chamber (5) at points such that they do not lie in the main flow of the swirl generated in the swirl chamber. <IMAGE>

Title: Method of automatic level control
Inventor: ESPRESTER RALF DR ING
IPC: H03G3/20
Filed: 1985-11-16
Abstract: In the proposed method of level control in a digital receiver, the scanned values are stored temporarily, and an average effective value is formed from N scanned values. By comparing this average effective value with a target value, a control signal is derived, and the temporarily stored values are then multiplied by it. Similarly, further average effective values can be formed from N of the following scanned values at a time, and used for tracking the control signal. For receiving frequency jump signals, starting from an expectation time of the signal, at least two successive groups, each of N scanned values, are processed to form an average effective value in each case. If the two effective values are the same, the temporarily stored scanned values are multiplied by the control signal and output. If the difference between the effective values is large, a third effective value is formed from N further scanned values, and compared with the second effective value. If the second and third effective values are within the preset tolerance window (difference </= 3 dB), the control signal formed from the second effective value is multiplied by the scanned values of the received signal, and this signal "controlled" in this way is output to the demodulator.

Title: Method and circuit arrangement for monitoring a digital transmission system
Inventor: KEILHOLZ HEINZ
IPC: G08B29/02
Filed: 1986-11-21
Abstract: In extensive digital transmission systems, monitoring of the different functions is essential in order to ensure reliable operation. These transmission system functions are often monitored by means of special monitoring circuits, the alarm signals of the monitoring circuits usually being evaluated by a control circuit in such a way that a display device with a number of light sources is activated, the display device having a smaller number of light sources than the number of different alarm signals. For clear display of the cause of the fault, changeover to a coded fault display by the light sources is effected by the control circuit. The number of different alarm signals which can be displayed can be increased in simple fashion in that the control circuit performs the activation and de-activation of the light sources with a flashing frequency.

Title: Apparatus for handling piece goods
Inventor: WAGNER NICO
IPC: B65G47/91
Filed: 1987-12-04
Abstract: Vacuum suction heads, which suck on a complete layer of piece goods, are used for handling piece goods. As soon, however, as one article of this closed layer of piece goods is absent, the suction force of the remaining channels fails since the then opened or free suction bores considerably reduce the vacuum suction force of the remaining suction surfaces due to the high suction flow. A suction plate is thus to be provided, with which complete layers of piece goods can be gripped, it not being necessary for the layer of piece goods to represent a complete closed plane. The object set is achieved in that the suction plate comprises a multiplicity of suction channels which are arranged in an uninterrupted sequence adjacent to one another and one behind the other and which form a large active surface and in that a perforated plate which covers the individual channels and is intended for throttling the suction flow is arranged at the upper end. <IMAGE>
