Title: Packing apparatus
Inventor: KRONSEDER HERMANN
IPC: B65B21/18
Filed: 1991-07-24
Abstract: ABSTRACT     The present invention refers to a packing apparatus used for filling or/and emptying bottle cases ox the like. The packing apparatus comprises an extension arm, which is adapted to have attached thereto a gripping head and which is articulated on two ar-ticulation points with the aid of steering means thus defining a steering rod system which is adapted to be moved after the fashion of the bars of a parallelo-qram, said extension arm being adapted to be moved in an essentially horizontal direction via a cam disk. In accordance with the present invention, the steer-ing system comprises a bipartite steering means whose steering components are adapted to be pivoted rela-tive to each other. By pivoting the two parts of the steering means relative to each other with the aid of a second cam disk and by changing thus the ef-fective length of the steering means defined by these two parts, an essentially vertical motion can be superimposed on the horizontal motion of the exten-sion arm, whereby an appropriate path for the grip-ping head can be generated.

Title: Call setup method for use with a network having mobile end users
Inventor: WANG THERESA CHEN YEN
IPC: G01S5/00
Filed: 1993-02-09
Abstract: A distributed communication network includes switching offices (SOs), moving-orbit satellites, and subscriber information managers (SIMs). A population of mobile units (MUs) communicates through the network.      A MU automatically determines its location and communicates with the network so that this information is kept current at a SO serving the MU and at a home SIM for the MU. The terrestrial nodes of the network have information showing which MUs are logged on at any given time. This knowledge is used to block calls to MUs known to be logged off. Calls are setup through cooperation between SOs. When calls are being setup to MUs, call-originating SOs determine appropriate SIMs and obtains the current location of the MUs from those SIMs. This current location corresponds to a call-destination SO with which the originating SO may cooperate in setting up a call.

Inventor: MANZ DAVID H
IPC: B01D24/12

Abstract: An intermittently operating slow sand filter uses the damming of water in a raised pipe to provide a constant level of water in a slow sand filter container. The container includes a water inlet and outlet, and is partially filled with sand or other filter material. A pipe from the water outlet in the slow sand filter is raised upward to the desired level of water over the sand before descending to a water reservoir. Water backs up in the pipe and the container to the desired level above the top of the sand, even when the flow of water is intermittent. The schmutzdeuke forms at the top of the filter medium.      The water level in such a manually operated slow sand filter, using fine quartz sand as the filter medium, and at ambient temperatures (about 21°C) is maintained above about 1 cm above the top of the filter medium and below about 8 cm above the top of the slow sand filter. In another intermittently operating slow sand filter, the water level is controlled automatically when not being used at a desired maintenance level, and otherwise is kept in a desired range of levels above the top of the sand (or other filter material) in a partially filled container. Automatic control is provided by a control system that senses the water level in the slow sand filter. The supply of water may be from a pump or from a gravity flow controlled by a valve. The water from the automatic intermittently operating slow sand filter is supplied to a reservoir.      Water level in the reservoir may also be controlled within a desired range using upper and lower level limit detectors and a valve on an outlet line from the container to the reservoir.

Title: One piece plastics closures
Inventor: BROWNBILL THOMAS D
IPC: B65D41/04
Filed: 1993-09-20
Abstract: A B S T R A C T            ONE-PIECE PLASTICS CLOSURE"      A one-piece plastics closure for a carbonated beverage bottle has a sealing ring which extends inwardly and downardly towards the closure mouth from its attachment to the closure body.  When the closure is fitted the ring extends around the outer radius and over the annular top face of the bottle neck, backed by a stepless abutment and reaction surface of the closure body.  The latter surface engages the sealing ring mechanically above the container top face to determine the fitted position of the closure and create a seal when the pressure in the bottle is low.  When the product pressure is high, however, the effective seal is made between the sealing ring and the outer radius of the bottle neck.  For that purpose the abutment and reaction surface is roughened, so allowing access for the product pressure to the back of the sealing ring.
