Title: Securing base for surface vegetation - uses concrete of high pore volume poured on site in garden or on roof
Inventor: MOEDINGER HILDEGARD
IPC: E04D11/00
Filed: 1990-04-17
Abstract: Concrete of high pore volume is poured on site.

Patent DE-4025194-A1 (DE)
Inventor: UEBEL HELMUT DIPL ING
IPC: B61L1/18
Filed: 1990-08-09
Abstract: A track circuit is disclosed, the receiver (E) of which carries out, for the purpose of track-release indication, a cross-correlation between a track voltage tapped off on the track (GL) and a reference voltage which is derived from the transmission signal of the track circuit transmitter (S) or generated separately. The maximum of the cross-correlation is sought by receiver (E) and compared with a predetermined threshold value. An embodiment with purely digital operation uses a track current source as transmitter which is controlled by a completely modulated transmission signal which is read out cyclically from a ROM. A microcomputer serves for calculating the cross-correlation function in the receiver (E) and for evaluating and tracking the maximum. The reference voltage is generated with the aid of a further ROM in the receiver (E) which is programmed in the same way as the transmission-side ROM. <IMAGE>

Title: Dialysis stations with a central supply - each have a pressure compensating bubble container under atmospheric pressure
Inventor: POLASCHEGG HANS-DIETRICH DR
IPC: A61M1/16
Filed: 1992-02-11
Abstract: The system to supply dialysis stations centrally, with a dialysis concentrate, has a supply container and a connected ring channel to be fed with concentrate under pressure. Branch channels (11) are connected to the dialysis stations through a valve assembly (17) and a pressure compensation vessel (23). Each pressure compensation vessel (23) is a bubble container (29) under atmospheric pressure. A given volume of concentrate is fed in through a hose connection (30) and an inlet (29a). Through the expansion, to compensate for pressure in the container, the concentrate passes out (29b) to the dialysis station without pressure. The level of concentrate in the bubble containers is controlled (31) by suspending the container (29) from a weighing beam (31) with a clamping wedge (33). The feed hose (30) passes between the wedge (33) and a fixed surface (35) so that the weight of the filled container (29) clamps the hose (30) between the wedge (33) and surface (35). An electrical level contents control can be fitted within the bubble container (29). The bubble container (29) is of a flexible plastics material, esp. PVC or PE. A filter housing with a hydrophilic membrane, with a mean pore size of max. 0.2 micrometer, is at the feed of the concentrate into the ring channel and at the delivery points into the branch channels, with a sterile filter for each. A sterile filter is integrated into the main supply container, or is in front of the supply container. USE/ADVANTAGE - The system is for an arrangement of a number of dialysis stations, where the concentrate is supplied from a central point for delivery under pressure to each station. The pressure compensation in each branch connection ensures that the concentrate is fed correctly, with a simply mfg. unit, without allowing the concentrate to be contaminated by contact with ambient air.
