Title: Ping pong ball toy
Inventor: BEARS JAMES A
IPC: A63H33/00
Filed: 1993-10-01
Abstract: ABSTRACT OF THE DISCLOSURE                       PING PONG BALL TOY A toy is disclosed consisting of two or more parallel nylon filaments under tension forming a segment of track across open space. One end of the segment is positioned higher than the other end, and a ping pong ball may then roll across large distances under gravity. Terminating elements at each end of a segment of track attach to fixed support surfaces such as walls and permit the parallel lines of filament to be tensioned across the open space crossed by the segment. Different segments may be interlinked to redirect the balls along further such segments of filaments, producing complicated travel paths through space limited only by the child's imagination.

Filed: 1994-01-17
Abstract: Intexchange carriers make their rate information for long-distance service available in a database 16. PBXs 40 and telephone central offices 31 access that rate information using ISDN and/or SS7 signaling and use it as a basis for determining which carrier to use at any given time in the routing of a call. Such accessing may be carried out on a call-by-call basis. Or a carrier's schedule of rates can be stored locally in the PBX or local switching office, thereby obviating the need for a database query for every call.
Patent CA-2114039-A1 (CA)
Inventor: HAYASHI HIROAKI
IPC: H04M3/58
Filed: 1994-01-24
Abstract: A telephone connection is established between a pushbutton telephone set and one of telephone lines through a pushbutton telephone set unit, a speech highway, and a telephone line unit.  When one of line and extension keys of the pushbutton telephone set is pressed by the user during the telephone connection, a CPU in a control unit determines whether the telephone connection is being made based on the period of time that has elapsed after the pushbutton telephone set has captured the telephone line.  If the telephone connection is being made as determined by the CPU, then the CPU controls a time switch circuit according to hold function data stored in a RAM to connect the telephone line unit to a hold tone generator through the speech highway, thus holding the telephone connection.  Thereafter, the CPU captures a telephone line corresponding to the depressed one of the line and extension keys.

Title: Process and machine for conditioning any products in containers such as barquettes
Inventor: FRUCHARD MICHEL
IPC: B65B31/04
Filed: 1994-03-24
Abstract: ABSTRACT         A process for conditioning products, such as foodstuffs, in containers having e.g. the shape of boat-shaped receptacles, involves advancing on a conveyor or the like a tubing film closed at its forward end and into which is sent a gaseous mixture and is housed at least a container filled with product.  The tubing film is sealed by welding in the area of the rearward end of the container and separated from the remaining portion of the tubing film.  The separated tubing film portion is then heat-shrunk.        Before welding the tubing film in the area of the rearward portion of the container, heated air is injected onto the external wall of the tubing film from its closed forward end until at least its portion corresponding substantially with the middle of the container so as to pre-shrink the tubing film with expulsion of the gaseous mixture rearwards.  Vacuum is then applied inside the tubing film from the rear portion to complete expulsion and facilitate welding of the tubing film at the rear portion of the container.

IPC: C12N15/10
Filed: 1992-10-12
Abstract: A screen aperture blinding prevention and liquid overflow prevention and level control apparatus for a knot drainer (100) senses liquid level (77) within the knot drainer (100) and compares the sensed level to a setpoint level. Differences in the two levels generate control signals of appropriate magnitude and direction, and those control signals are transmitted to a valve (140) whose degree of responsiveness and openness is adjusted to change the outflow rate of accepts liquor from the accepts chamber (80) of the rejects separator. In addition, passive level control is provided in the discharge line for establishing accept flooded screen apertures (61) regardless of variations of inflow and outflow rates during operation while active level control to create accept flow rate greater than, less than, or equal to inlet flow rate is provided by the combination of siphonic loop (170), barometric leg (55) and control. Continuous flow of fiber and liquid through separating screen apertures is appropriately supervised by monitoring accepts chamber (80) pressure.

Abstract: A method and apparatus of maintaining tension in the film over the forming shoulder in the forward and reverse directions of a package formed in a vertical form, fill and seal machine and stripping and/or settling products out of the sealing  and severing area of a partially formed package.   The machine includes a source of film, a measuring axis, a forming shoulder, a pull axis, and a finishing system for stripping, sealing and severing successive packages from a formed tube.  The measuring axis and the pull axis are operated in the forward direction to form a film tube while tension is maintained on the tube.  After a predetermined length of tubing has been pulled, the measuring axis is operated in the reverse direction while the tube is retained  in  tension  downstream of  the  forming  shoulder.          Stripping of product entrained in the film seal area can occur in the reverse direction.  Product can also be settled in the tube  by  alternately  operating  in  the  forward  and  reverse directions, or by operating in a stepwise fashion in the forward direction as product as injected into the tube.

Inventor: EDWARDS DONALD WILLIAM
IPC: D02G3/28
Filed: 1994-05-25
Abstract: A system for bonding alternate S and Z twist plied yarn. The system bonds the plied yarns (10A, 10B) as they move in a path through the process and permits balanced expansion of the yarn (30) while preventing lateral movement out of the path. The bonding of the yarn strands while plied together, forms a bond characterized by a dense region (404) of filaments adhesively joined together where one of the strands (10B) overlaps another strand (10A), followed by a less dense region (401) along the one strand where fewer filaments are adhesively joined, followed by another dense region (403). A stronger, more reliable bond results.
