Patent DE-4237904-A1 (DE)
Title: Flow control for a dosing flow - uses part flows for setting to give the required flow in trouble free action even for small volumes
Inventor: METTE PETER
IPC: C12C11/02
Filed: 1992-11-10
Abstract: To control the flow of a material for dosing, esp. a suspension of brewer's yeast, an initial vol. flow Q(p) is generated by a pump system in a generally constant flow set between an upper and a lower value. A second vol. flow Q(v) is exchanged between the pressure and suction zones of the carrier and determined between a min. and max. value. The vol. flow Q(d) for dosing is a result of the vol. flow difference Q(p) - Q(v) = Q(d), to be passed to the suction zone and out of the pressure zone. On achieving the min. value, the two vol. flows Q(p), Q(v) are evenly increased, and evenly decreased on reaching the max. value. Also claimed is an appts. with a control valve (3) and two valve housing sections (3.1, 3.2) interconnected by a control valve seating, and each with two connections. The suction side (S) of the pump (7) system is linked to a connection of one section and the pressure side (D) is joined to the connection at the other section of the housing parts (3.1, 3.2). A flow channel (2a) is fitted to the second connection at the suction side valve housing part (3.1) and a dosing channel (2b)is linked to the second connection at the pressure side valve housing section (3.2). USE/ADVANTAGE - The system is for the control of a flow for dosing, esp. a suspension of yeast for beer brewing. The operation gives a trouble-free dosing action, even of small vol. flows, with allowance for strongly shifting viscosities and different yeast consistencies.

Title: Switching to receivable alternative frequency of RDS receiver - switching reception frequency from instantaneous one to that of another station, when changeover condition exists
Inventor: RINDERLE HEINZ DIPL ING
IPC: H04H40/18
Filed: 1992-11-26
Abstract: The method involves using an intermediate frequency (IF) amplifier whose bandwidth is changed-over in dependence on interference signals, whose frequencies are outside a useful channel especially for frequencies of neighbouring channel signals. The changeover switching condition contains a changeover criterion, derived from the reception quality of the RDS system, and a second changeover criterion. The resulting IF wide band changeover criterion, carried out over a certain time period, are evaluated. The second changeover criterion includes the time period of such conditions, in which the IF bandwidth is limited. USE/ADVANTAGE - For RDS traffic, esp. for vehicle radios. Quality improvement combining RDS transmission with reduced intermediate frequency bandwidth.

Title: Communication system for a crane installation
Inventor: MOELICH HORST DIPL ING
IPC: H02B1/24
Filed: 1993-06-11
Abstract: The invention relates to a communication system for a crane installation in a container yard. The crane installation comprises a crane path several hundred metres in length on which a crane is movably disposed. A crane installation of this type requires a plurality of communication channels between the fixed installation part and the crane. According to the invention, a dedicated loop system is provided for communication and powerline carrier (PLC) units are provided for converting the AF channels to carrier-frequency transmission mode. In order to prevent high contact resistances on the loop contacts, the loop system is also used to supply power to the PLC unit located on the crane. The PLC unit in the fixed installation part is connected to the start of the loop system. Thus, the piece of the loop system from the loop contacts to its end acts as a spur. The invention also discloses how the development of waves which interfere with communication on the spur is prevented.

Title: Luggage container
Inventor: WALLNER HEINRICH PROF
IPC: B62J9/00
Filed: 1993-09-13
Abstract: The invention relates to a luggage container, in particular for two-wheeled vehicles, with a container body (3) which can be varied in dimensions and can be closed by a lid (4). The container body (3) is formed by a number of segments (5, 6, 7, 8) which each comprise two essentially circular sector-shaped side walls and an outer wall which connects the circumferential edges of the two circular sector-shaped side walls to one another to form a U-shaped segment. The side walls and the outer walls of the individual segments have radii or lengths which are graduated in such a manner that the individual segments can be arranged nested together. The free, pointed ends of the side walls of all segments (5-8) are connected pivotably to one another by a common shaft (10b), with the result that the dimensions of the container body can be changed between a minimal size in which all the segments are arranged in one another, and a maximum size in which they are pivoted out of one another. <IMAGE>

Title: Arrangement for testing objects at different temperatures, in particular for testing at rapidly varying temperatures
Inventor: HEHL KARL-HEINZ DIPL ING
IPC: G01N3/60
Filed: 1993-10-27
Abstract: The invention relates to an arrangement (10) for testing objects (44) at different temperatures, in particular for testing under rapidly varying temperatures, comprising two chambers (18, 20), arranged one above the other and capable of being set to different temperatures, as well as a lifting device (22) which holds the objects and can be moved from one chamber to the other. In order to prevent the possibility of an underpressure or an overpressure being produced in the chambers, it is proposed for a controlled pressure equilibration to be carried out between the upper and lower chambers (18, 20) when the lifting device is aligned with the upper or lower chamber. <IMAGE>

Title: Device for stripping the insulation off round wires
Inventor: ARNOLD ERNST
IPC: H02G1/12
Filed: 1993-10-26
Abstract: A coil winding machine has at least one integrated stripping/wire guidance unit which contains a stripping head (20) which is connected to a hollow drive cylinder (21). Three toggle levers (26), which are fitted with metal-cutting tools (blades 28), are mounted in the stripping head such that they can pivot, are pressed by centrifugal weights (flyweights) (29) against the wire (40), which is passed between them, when the stripping head rotates, and remove the insulation from said wire (40). A setting spindle (23) passes through the hollow drive cylinder (21), has a scale ring (25) at its outer end and its other end engages in the thread of a stop screw (24) which allows displacement by rotation of the setting spindle in the axial direction and forms a stop for the conically running toggle lever (26). Depending on the position of the stop screw, the movement of the toggle levers is limited earlier or later, so that the stripping blades can be accurately set to the wire thickness. <IMAGE>
