Patent DE-3611344-A1 (DE)
Title: Synchronisation method
Inventor: HERHOLT ANDRIES
IPC: H04K3/00
Filed: 1986-04-04
Abstract: To protect against deliberate intelligent external interference, a broadband transmission technique, particularly using a frequency hopping method, is used for mobile transceiver stations in tactical use. In this connection, it is of importance that this interference-resistant transmission technique is used as early as in the synchronisation phase during the setting-up of the connection. To be able to use this technique in this case not only in half-duplex mode between two subscriber stations but also in the case of a global call in simplex mode during the transmission of information from one subscriber station to a relatively large number of other subscriber stations, it is proposed to carry out a coarse network synchronisation in half-duplex mode via a subscriber station (master station) exercising a supervisory network function during the setting-up phase of the radio network, using a slow frequency hopping idle mode so that a fine synchronisation can then be achieved in each case during the setting-up of a connection between subscriber stations in simplex mode before the actual information is transmitted. <IMAGE>

Patent DE-3637851-A1 (DE)
Title: Control unit for lubricants metering
Inventor: GANTNER ROBERT
IPC: F16N29/02
Filed: 1986-11-06
Abstract: The invention relates to a control unit for the metering of lubricant to at least one lubrication point in a manner independent of the supply pressure. In this unit, at least one first fixed restrictor and a pressure balance with an adjustable restrictor are arranged in series in a housing, in a connecting line between a supply connection and a lubrication point connection, the pressure balance having a spring-loaded control element for the adjustable restrictor, this control element being subjected to the pressures upstream and downstream of the first fixed restrictor. Known control units of this kind have the disadvantage that the metering of lubricant cannot be adapted to different operating conditions at the lubrication point which require significantly different volume flows. According to the invention, in contrast, the proposal is that the adjustable restrictor should have assigned to it in the housing a further fixed restrictor in addition to the first fixed restrictor and that a control device should be provided by means of which at least one of the fixed restrictors in the connecting line from the supply connection to the lubrication point connection can be selectively deactivated. By means of the control device, one of the two or both fixed restrictors are selectively employed in order to adapt the volume flow of lubricant to different operating conditions at the lubrication point.

Title: Device and method for removing air and gas bubbles from meat poured into a cooking mould and for compression thereof
Inventor: SOMMER PETER
IPC: A47J43/20
Filed: 1987-09-03
Abstract: A device and method for removing air and gas bubbles from meat poured into a cooking mould and for compression thereof. In known devices and methods of this type, the meat is compressed after evacuation in a chamber by means of a pressure ram, evacuation is terminated and a lid is placed on the cooking mould when the chamber has been opened. During the period between the lifting of the pressure ram and the placing of the lid in position, the pressed-in meat can expand once again and a considerable amount of air can penetrate the meat filling, which can lead to the occurrence of undesired decaying action. This is prevented by means of the method and/or the device according to the invention, in that the lid is placed in position only after the chamber has been evacuated and is locked after compression of the meat using the mould, so that the occurrence of air bubbles in the meat after removal of the mould from the chamber is entirely prevented.
