Title: Automatic packaging machine for closing over filled boxes
Inventor: TISMA STEVEN
IPC: B65B35/38
Filed: 1987-09-17
Granted: 1992-07-14
Abstract: ABSTRACT OF THE DISCLOSURE     An automatic packaging machine includes a loading  station for simultaneously and sequentially picking up a plurality of elongated products and deposing them in a spaced parallel alignment within a box. At the time of loading each of the products has an initial volume which is substantially greater than the volume which the same product will have after it has settled over time within the box. Thus, the box is overfilled by an amount which will make it full after the products have settled.  Then, the overfilled box is advanced to a closing station, where the lid is closed over the filled box without damage to the products.  This immediately reduces the volume of the products to the volume which they would have after they have settled.

Title: Mobile vortex shield
Inventor: SCHILLER ALAN J
IPC: B01F3/04
Filed: 1987-11-10
Granted: 1994-02-22
Abstract: ABSTRACT OF THE DISCLOSURE       An apparatus for use with propeller type aspirating aerators for preventing the formation of vortices near an aerator propeller in a substance in which the propeller is driven. The device comprises a mobile floatable shield which floats on the aerated substance and elim-inates a vortex by being drawn into one by the vortex's own swirling motion and contacting the vortex. The shield may be flexibly attached to a frame which also houses the aerator. Because the shield is not connected to the aerator, floats on the surface and is mobile, many of the problems faced with the prior art devices have been eliminated: the shield is easier and cheaper to manufacture; material does not wedge between the aerator and the shield; any problems with the shield are visible; the shield stops virtually all vortices; and vibration problems are eliminated.

Title: Tracking system with beam switching antenna
Inventor: YAMANE TOSHINOBU
IPC: G01S3/42
Filed: 1988-05-30
Granted: 1992-03-31
Abstract: Abstract of the Disclosure:         In a tracking system of a stationary satellite, a phased array is used for an antenna mounted on an automobile.  The phased array antenna has a sharp beam which is switched between two different directions in azimuth.  The antenna beam is switched between the two directions periodically by control of phase constants in a feeding circuit of the antenna and comparison is made in strength between signals received before and after the beam switching to obtain an error signal as an azimuth error signal.  Then, the antenna is mechanically moved in azimuth according to the azimuth error signal until the azimuth error signal becomes zero.  In a case the antenna beam is also switched between two directions in elevation, the antenna beam is switched in elevation during an interval between successive two times of the beam switching operation in azimuth and detects a difference in strength of signals received before and after the switching in elevation to thereby produce the difference as an elevation error signal.  The antenna is mechanically moved in elevation according to the elevation error signal until the elevation error signal becomes zero.

Abstract: Abstract Method and Facilities for Hybrid Packet Switching In fast packet-switching networks, packets of particular connections (CS1, CS2) (e.g., voice, moving-image) are to be treated with priority over packets of other connections (PS1, PS2, PS3) (e.g., data) (without delay jitter and loss of information).          Prior art arrangements are divided into a circuit-switching portion (for CS1, CS2) and a packet-switching portion (for PS1, PS2, PS3).  The circuit-switching portion operates on a time-division multiplex basis.  On each incoming line, 70 packets each containing 40 octets, for example, are combined into a frame.  If no special steps were taken, delays on the order of 40 x 70 x 8 bits = 22,400 bits would result in each switching stage; for each input of a switching stage, 22,400 bits of storage would be necessary.  According to the invention, all packets are divided within the exchange, into subpackets of equal length and distributed to subframes.  Switching takes place on the basis of subframes.  Delays and memory location requirements are reduced in the ratio of frames : subframes.  Preferably, the connections (CS1, CS2) to be treated with priority are assigned fixed positions in each frame and each subframe throughout the call.          Subpackets of the other packets are preferably inserted in sequence into free positions, and are recombined into complete packets within each switching stage.
