Abstract: A bidirectional cable network having a signal distribution system that prevents undesirable energy in the bidirectional cable network's return path from adversely effecting the entire network. The signal distribution system a first signal transmitted in a forward path direction over the bidirectional communication path from a headend to a plurality of remote points. Signals transmitted in a return path direction are time division multiplexed on a series of cyclically reoccurring time slots where at least one of the cyclically reoccurring time slots is assigned to each of the plurality of remote points. At least one primary is effective during each occurrence of the cyclically reoccurring time slots for isolating all of the plurality of remote points from accessing the network to transmit a signal in the second direction except for one of the plurality of remote points which is assigned the cyclically reoccurring time slot that is presently providing a path to transmit in the second direction from the remote point to the headend. In one embodiment each return gate services a plurality of remote points within the return gate's distribution branch. In a second embodiment each remote point has a dedicated return gate.

Abstract: Carton liners are used in freezing frames for the preparation of large frozen blocks of fresh food material, e.g. fish fillets. The liners have a lid with skirt flaps to be closed upon filling of the liner, and care should be taken that the lid flaps be located at the outsides of the liner walls inside the freezing frame, as they may otherwise be embedded in the material to be frozen and thus disturb the regularity of the frozen block material. The same applies to corner flaps which, already by the mounting of the liner, should be folded to assume an exterior position. According to the invention, in order to ascertain a correct mounting and closing of the liners once they have been removed from the freezing frames, such liners are used which are provided with printed marking (A, B, C) on those outside area portions that are to be covered by exterior liner/lid flaps, and the closed liners are inspected for detection of any visible marking, which will be indicative of a potentially defect block product.

Abstract: It is known to use a streaming current detector (SCD) in a system for monitoring the charge condition of a sample fluid and for controlling the addition of a flocculating/coagulating agent to the fluid. I t is further known to arrange the SCD to monitor a sample taken from the fluid supply, and to connect the SCD in a feedback loop to directly control the dosing of the flocculating agent into the fluid supply. Difficulties arise in complex systems, and improper control over flocculant dosing results from the effect of dosing adjustment being overshadowed by other charge-varying influences. The invention propose s a solution in which a secondary feedback loop involving dosing of a chemical (which may be the same as that added to the main supply ) into the sample supply is provided aroung the SCD itself. In this way, the corrective effect of the secondary dosing is not overwhelme d by the other influences.

Abstract: For measuring the level of a material in a container on the basis  of  the  radar  principle,  microwaves  are  radiated downwards and reflected microwaves received by means of the antenna of a ranging device arranged above the highest level anticipated.  In the normal measuring operation the received microwaves are evaluated in the distance range up to empty distance corresponding to the distance of the antenna from the bottom  of  the  container  for  determining  the  echo  waves reflected from the surface of the material, for measuring the transit time of the echo waves and for computing the distance of the material surface from the antenna of the ranging device from the measured transit time.  In order to reliably detect the empty condition of a container having a curved bottom, despite the multiple reflections of the microwaves reflected from the container bottom, when no echo waves are detected in the distance range up to the empty distance, the evaluation is done in an enlarged distance range and any echo waves detected in the enlarged distance range beyond the empty distance are assigned to the empty distance.
