Inventor: FLIERL KLAUS
IPC: C09B67/54
Filed: 1987-10-08
Granted: 1991-11-19
Abstract: Separation and purification of pigment suspensions and suspensions of pigment intermediates by a membrane separation process Abstract the Disclosure Process for separating and purifying pigment suspensions and suspensions of pigment intermediates in a liquid by means of a membrane separation process, whereby the suspension to be treated is uniformly fed to and circulated through a microfiltration unit containing at least one semi-permeable membrane and the separated liquid flows off through the membrane as permeate, which process comprises replacing the permeate gradually by a washing liquid that differs from the first liquid such that the total amount of washing liquid fed into the system is 1 to 15 times the total volume of the initial suspension, and separating the resultant suspension from the liquid by means of conventional filtration or drying apparatus.            The process is particularly suitable for processing fine pigment suspensions often obtained in pigment synthesis.

Title: Trap for capturing animals
Inventor: LUKE JOHANNES
IPC: A01M23/26
Filed: 1987-12-29
Granted: 1991-07-23
Abstract: Abstract:      The invention relates to an animal trap having at least two shackles preferably produced from flat or rod iron, such shackles being situated opposite each other in plate hinges and turnable therein about mutually offset pins and maintained under tension by springs.  Both hinge sheets are separated from each other by means of a connecting web that forms the medial longitudinal axis of the trap.  A release mechanism is attached to the connecting web and is held in such a way as to be capable of movement.  The release mechanism has an element suitable for accepting bait, which release mechanism, when the trap is in the primed position, acts with a first one of the shackles in order to lock the trap in such a position.  By means of the offset placement of the pins, one shackle acts as a stationary shackle while the second shackle acts as a striking shackle, inasmuch as the latter strikes the animal, killing the latter in the appropriate spot.

Title: Computer workstation including video update arrangement
Inventor: KIRK JOHN
IPC: G09G1/02
Filed: 1988-05-27
Granted: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE     A computer workstation including a processor, one or more input/output units, such as disk devices or network interfaces, a program memory and a video memory which contains video information displayed on a video monitor.  An arbitration circuit selects among the processor and input/output units for transfers to and from the program memory and video memory.  A master control circuit controls timing of transfers to and from the program and video memories, and periodically enables video update transfers of video information from the video memory to video control circuits, which control the video monitor.  While a video update is in progress, the master control circuit holds off other transfer request of the processor and input/output units with the memory.  The program memory stores interrupt vectors.  In response to interrupt requests from units which require interrupt service, the master control circuit interrupts the processor.  When the processor acknowledges the interrupt, the master control circuit enables the transfer from the memory to the processor of the interrupt vector associated with the highest priority interrupt.

The system uses a first source of  gas  under  pressure  which  may  be  a  low pressure  source suitable for a continuous operation of the blending apparatus.          The system also is connected to a high pressure source of air such as plant air which is utilized as a supplemental source of air under pressure for initial start-up of the apparatus. control system is provided which regulates the flow of the high pressure  air  to  the  gas  supply  conduit  which  acts  as  a reservoir for high pressure air.  The control system allows the gas  supply  conduit  to  be  pressurized.   This  high  pressure source  flows  rapidly to  the vessel at start-up to  break an initial head of material which may be lodged in the vertical lift  column  of  the  blending  apparatus  thereafter  the  high pressure source of air is no longer utilized in normal blending operation.     8212D/bid-4

Title: Queue based elevator dispatching system using peak period traffic prediction
Inventor: THANGAVELU KANDASAMY
IPC: B66B1/20
Filed: 1989-06-20
Granted: 1993-01-26
Abstract: Abstract Queue Based Elevator Dispatching System Using Peak Period Traffic Prediction Elevator system with multiple cars (1-4) and a group controller  (32)  having  signal  processing  means  (CPU) controlling car dispatching from the lobby  (L).   During peak conditions  (up-peak,  down-peak and noontime),  each car is dispatched and assigned to hall call floors having a large predicted number of passengers waiting on priority basis, resulting in queue length and waiting time at the lobby and upper floors being decreased, and system handling capacity increased.   Estimations of future traffic flow levels for the floors for five minute intervals are made using traffic  levels measured during the past few time intervals on that day as real time predictors,  using a linear  exponential  smoothing  model,  and  traffic  levels measured during similar time intervals on previous similar days  as  historic  traffic  predictors,  using  a  single exponential smoothing model.   Combined prediction is used to assign hall calls to cars on priority basis for those floors having predicted high level of passenger traffic to limit maximum waiting time and car load.  Noontime priority scheme is based on multiple queue sizes and percentages of maximum waiting time limits.  Different waiting time limits can be used for lobby and above lobby up and down hall calls with automatic adjustment.  During up-peak the lobby is given high priority.  The lobby queue is predicted using passenger arrival rates and expected car arrival times. Down-peak operation uses multiple queue levels and per-centages  of waiting time  limits,  with estimated queues based on passenger arrival using car-to-hall-call travel time.
