MUCKENFUHS                        ABSTRACT OF THE DISCLOSURE         An easy open flexible bag preferably containing one or more stacks  of  flexible  articles  which  are  maintained  in  a  state  of compression in a direction substantially parallel to their thickness. For products such as disposable absorbent baby diapers,  catamenial pads,  incontinent  briefs  and the  like,  the degree  of compression within the bag may be as much as 50% or more when compared to the uncompressed thickness of the stack of articles in question.   In a particularly preferred embodiment, the bag totally encloses the stack or stacks of compressed flexible articles and exhibits a substantially rectilinear shape.  The bag preferably includes an integral carrying handle.  The side panels and the front and back panels of the bag are subject  to  tension  imposed  by  the  stack  of  compressed  flexible articles.  The top of the bag is closed by forming inwardly folded side gussets  and sealing the vertically extending portions of the front and back panels to one another above the uppermost surface of the product contained within the bag.  A continuous line of weakness spanning a tensioned side wall of the bag and continuing into the closed uppermost end of the bag is provided.  The portion of the line of weakness in the uppermost end of the bag is preferably located near, most preferably slightly inboard of, the innermost portions of the opposed inwardly folded side gussets such that the bag may be easily opened by grasping the outermost edge of the top of the bag and partially separating or completely removing the corner of the bag, along with the included side gusset,  along the continuous line of weakness.  Partial separation or complete removal of a portion of the tensioned side panel of the bag allows the coinciding portion of the stack of compressed articles to project in fan-like array through the aperture thus created to permit easy one-at-a-time removal.

Title: Two-way paging system with answer-back function
Inventor: MINAMI YOICHIRO
IPC: H04J3/06
Filed: 1992-02-24
Granted: 1997-02-25
Abstract: After bit synchronization and frame synchronization are established in accordance with a transmission signal from a transmission office, reception RX is stopped until a reception timing assigned to a group of a portable radio unit comes.  A receiving operation is performed again at the reception timing assigned to the group of the unit.  If the ID code of the received signal coincides with the ID of the unit, an informing operation is performed.  At the same time, transmission TX is performed.  A transmitting operation is performed during a transmission signal stop period TXOF upon completion of transmission of data corresponding to all the eight groups.  The transmission timing of the portable radio unit is based on the fact that frame synchronization is established in the reception RX, so that transmission TX is performed at a timing assigned to the group of the unit in the reception RX.  The above-described timings prevent the transmission office and the portable radio unit from performing simultaneous transmission.

Title: Water controlling building block
Inventor: SAUVE DENNIS L
IPC: E04B1/70
Filed: 1992-03-31
Granted: 1998-07-07
Abstract: A hollow rectangular concrete building block is provided having features which prevent and impede the infiltration of water into and migration of water through the block. The hollow block conventionally includes parallel interior and exterior vertical walls with at least one transverse vertical web spanning between the walls to form a unitary block with an interior cavity. Migration of water from the exterior to interior is impeded by a plurality of vertical ribs protruding from each side surface of the web. Water which has penetrated into the block cavity is redirected downwardly, as it trickles acrossthe web, by the ribs to be ultimately expelled at the base of the block array with conventional flashing and weep holes. Grooves in the upper surface of the webs prevent migration of water along the upper surface and redirect the water to flow downwardly along the side surfaces of the web. The upper exterior edge of the exterior wall of the block may preferably be beveled particularly in the application of the invention to architectural masonary units where the mortar beads may be inset from the block faces up to 3/4 of an inch for visual effect. Bevelling the exterior edge is done to prevent pooling of water in the mortar joint area; to shed water downwardly along the exterior surface of the exterior wall; and to enable access to the joint for sufficient compaction of the mortar joint prior to setting, thereby minimizing cracks in the finished mortar through which water may infiltrate into the block cavity.

Abstract: An automatic lighting controller applies a turn-off control signal to a gate-controlled power switch for switching OFF lighting when a timer circuit determines that motion  activity  exceeding  a  threshold  level  has  not occurred within a service zone during a predetermined time interval.  A binary counter produces a grace period count signal and a reset count signal, with the grace period count signal occurring during a predetermined sub-interval, for example, one count cycle prior (N-1) to the reset count signal (N).  The grace period count cycle (N-1) interval is adjustable, for example, from about 0.6 second (for test purposes)  to about 14 seconds.   The grace period count signal enables an audio transducer that provides an audible alert that the lights are about to be switched OFF automatically.   A person in the service zone can override the impending automatic shut-off simply by initiating some motion activity during the grace period.
