Title: Concrete blocks having through holes for water drainage
Inventor: METTEN JOSEF
IPC: E01C11/22
Filed: 1993-12-08
Abstract: Concrete Blocks Having Through Holes for Water Drainage ABSTRACT          In the case of concrete blocks having thin through holes for water drainage (perforated blocks), in particular paving stones of various formats and sizes that can be laid on surfaces exposed to the rain, such as streets, paths, squares, parking areas and rings around planted trees, and can be filled by means of jointing means or by means of sand at the lateral ends, the problem exists that the holes become plugged upon jointing or sanding-in.  In order to prevent this, the holes are closed at their top end, and indeed until the jointing or sanding-in operation is complete.  This is advantageously accomplished by means of a filling agent that can be floated away or dissolves by means of the addition of water (Figure 1).

IPC: H04Q3/00
Filed: 1994-05-11
Abstract: An arrangement for pooling service circuits so that they become available to a plurality of switching systems in a telecommunications network. Aregional control node receives a request for a service circuit to be connected to a call. The regional control node maintains the availability status of the service circuits in a pool for the region. In response to a request for a service circuit, the regional control node selects an appropriate circuit and transmits order to the switches and the circuit to establish the proper connections among these units in order to associate the service circuit with the requesting call. Advantageously, such an arrangement permits a large pool of individually expensive service circuits to serve a largenumber of switching systems, thus, increasing the efficiency of utilization of these service circuits. The arrangement is also used for controlling the allocation oftransmission resources to any call, thus optimizing the use of the regional transmission resources.

Inventor: SIMHAEE EBRAHIM
IPC: B65H35/10
Filed: 1994-09-20
Abstract: A plastic bag dispenser holds a continuous roll of bags, connected by perforated separation lines.  The dispenser is provided with a tongue, which the bags are dispensed over, that engages the separation line between the bag at the end of the roll and the next bag.   This begins the separation of the separation line, as well as holds the next bag behind the tongue. A finger is provided on the upstream side of the tongue, with a gap between the finger and tongue.  As a bag is separated, a portion of the front edge of the next bag is held in the gap, holding the bag in position for the next user.  The roll of bags rests in curved grooves in the dispenser that cause the roll to abut  and  frictionally  engage  an  interior  surface  of  the dispenser, preventing free-wheeling of the roll.  The curvature of the grooves causes the component of force which creates the frictional  engagement  to  increase as  the  size of  the  roll decreases.

Title: Flush-interval indicator for soluble pouches
Inventor: SCHNEIDER BARRY L
IPC: A61F5/445
Filed: 1995-01-13
Abstract: A flush-interval indicator for soluble, toilet bowl discardable pouches is disclosed for indicating to a user, once the pouch is discarded in a toilet bowl, when a sufficient flush-interval has elapsed so that, when the toilet is then flushed, the pouch will quickly disintegrate without obstructing or impeding the flow of water and waste material through the discharge lines of the system.  The flush-interval indicator comprises optically-distinguishable indicia printed or otherwise affixed to a display surface of a pouch and normally concealed by a water-soluble opaque layer.  The opaque layer may take the form of an external panel secured to the pouch, or a water-soluble layer of the pouch itself which includes pigment to render it opaque and shield the indicator from view.  In an alternate construction, a water-soluble external cover is secured to the pouch and fibers from the cover are heat sealed into the pouch's display surface to form a flush indicator that is relatively unreadable when the cover is dry.  However, when the pouch is exposed to water, the cover dissolves or disperses, after a sufficient flush-interval has elapsed, to reveal the flush indicator formed from the embedded fibers.
