Abstract: HOPPER BIN CONSTRUCTION            ABSTRACT OF THE DISCLOSURE           An annular chamber is formed around the open base of a bin and includes a shut-off gate assembly in the base thereof.   Stored grain fills the base of the chamber around the discharge area of the bin into the chamber up to the angle of repose of the grain.   A fan unit is secured through the wall of the chamber above the angle of repose and ambient air is discharged into the chamber and diffused through the grain mass in the base of the chamber and upwardly through the grain in the bin.          A perforated floor portion of the bin acts as the upper wall of the chamber and a percentage of the air diffuses through  this  perforated  floor portion  and assists  in diffusing the air equally through the grain mass in the bin particularly towards the outer wall of the bin.

Abstract: ABSTRACT                          VIDEO CODER    The  current  frame  of  the  picture  is compared (2) block-by-block with the previous frame to identity changed picture  elemente  (pixels).   The  resulting  matrix  is matched   (vector  quantised')  (4)  to  one  of  a  set  of standard matrices ('VQ shapes'). Only those pixels flagged by the selected VQ shape are transmitted plus a "VQ shape code".  This technique is modified in that the current frame is also compared (30) with a "background" frame stored (31) at the transmitter and at the receiver. Where,  for any block,  all the pixels flagged by the VQ shape are indicated by the second comparison as being the same as the background, the pixels are not sent - instead a  shape  code  plus  a  "copy  background"  instruction  is transmitted.

Title: Method of testing the magnesium content of magnesium-treated cast iron
Inventor: DAWSON JOHN V
IPC: G01N33/20
Filed: 1989-01-31
Granted: 1994-09-13
Abstract: ABSTRACT A METHOD OF TESTING THE MAGNESIUM CONTENT OF       MAGNESIUM-TREATED CAST IRON    }n the manufacture of ductile iron it is important to  know  that  the  magnesium  content  is  above  (or possibly below)  a threshold value.   It is known that the presence of magnesium prevents  tellurium causing solidification  of  a  sample  with  carbidic  eutectic arrest.  Accordingly we treat a sample in a receptacle with a know quantity of sulphur  (or selenium)  such as just to neutralise the threshold quantity of magnesium, then  we  observe  whether,   on  solidification,  the eutectic arrest is graphitic (indicating that more than the  threshold  quantity  of  magnesium  is  present)  or carbidic,  indicating less magnesium.   The observation is most    simply    done    (and    can    be    done semi-automatically)  by timing a cooling curve between two predetermined temperatures.

The eyelet is crimped such that crimped fingers or tabs of the eyelet cause the eyelet to be mechanically retained in the hole.  The tabs are curved so that the tabs do not lie flat upon the conductive pad.  The bottom Or the PCB is then wave soldered so that a base of the eyelet is electrically coupled to a conductive layer on the bottom of the PCB and the tabs are electrically coupled to the conductive pad.

Title: Broadband packet switch with combined queuing
Inventor: GIACOPELLI JAMES N
IPC: H04L12/56
Filed: 1989-05-12
Granted: 1992-12-22
Abstract: Abstract of the Disclosure A novel packet switch architecture is disclosed. The packet switch utilizes internal queuing (i.e. recirculation loops) and output queuing (i.e. multiple paths to each destination) to provide a packet switch which offers superior performance in comparison to a packet switch which utilizes either of these queuing strategies alone. The combination of recirculation and output queues have complimentary effects. The output queuing reduces the number of recirculation loops needed and recirculation reduces the bandwidth requirements for an output buffered switch.

Title: Railroad freight car with well for stacked cargo containers
Inventor: HILL CHARLES C
IPC: B61D3/20
Filed: 1989-07-25
Granted: 1995-04-04
Abstract: A multi-unit articulated railway freight car defining a container well in each of the several units, with container support members attached to the side sills of each unit to support standard intermodal cargo containers at a location low enough to permit a second tier of containers to be stacked atop a bottom tier without exceeding the maximum height restrictions of most main railroad lines, although ample clearance is preserved beneath the bottom of the car when fully loaded.  Each container support member is constructed of thick plate steel of high strength, formed cold to include residual internal stresses in order to resist failure when subjected to the loads imposed by sup-porting loaded containers carried in the container well.          The side sill structures are of box tube and formed sheet construction of small enough width to permit carriage of newer, larger, sizes of intermodal cargo containers without the car or containers protruding out-side the clearance available along most railroad lines.          A truss structure interconnects the bottom chords of the side sills and interconnects the cargo container support members.  Members of the truss structure are attached to the cargo container support members by hinges.

Abstract: TRANSFECTION HIGH-VOLTAGE CONTROLLER A transfection high-voltage controller for directing high voltage currents to a suspension of cells and DNA comprising a control section, a power store, and a highjoule switch. Under control of the control section, the high-joule switch directs a high-voltage current from the power store to a load such as a cuvette. The high-joule switch comprises a semiconductor controlled rectifier (SCR) having a gate coupled to the control unit for triggering the device, an anode for receiving the highvoltage current from the power store, and a cathode for delivering the high-voltage current to the cuvette. A current sink may be connected to the anode of the SCR to render it non-conductive a predetermined time after the high-voltage current appears at the cathode. Multiple SCRs may be connected in series to support voltages over 3,000 and currents in excess of 125 amperes, and a trigger control unit may be attached to the gate of each SCR in the series to effect simultaneous or serial triggering of the group.
