Title: Paper pressing arrangement for typewriters
Inventor: GILLIO CLAUDIO
IPC: B41J13/16
Filed: 1990-06-13
Granted: 2000-09-19
Abstract: The paper pressing arrangement comprises a paper guide plate for guiding a sheet of paper around a platen roller towards the typing line. The paper guide plate comprises two conveyor modules each of which supports three paper pressing rollers and is provided with a pivot element projecting from the barycentre of the triangle joining the midpoints of the three rollers. A control mechanism, in an operative position, transmits by means of a rocker lever pivotally connected to the pivot elements the action of a spring to urge the conveyor modules against the roller. The control mechanism comprises a lever for positioning the two conveyor modules in an inoperative position to permit insertion of the sheet of paper.      Each conveyor module defines a first axis for rotation of two front paper pressing rollers and a second axis spaced from the first axis for rotation of a rear roller disposed intermediate each pair front rollers. The paper pressing rollers have a rotary shaft of plastics material and a covering of rubber. Each conveyor module comprises, for each paper pressing roller two depressed seats for accommodating the shaft without force, and a through slot positioned between the two depressed seats. The through slot is of a width which is slightly less than the diameter of the paper pressing roller so that, in mounting, the rubber covering on each roller has to be slightly forced into the slot to permit the ends of the shaft to reach the seats. Each paper pressing roller then remains restrained between the two seats and the respective slot and will be capable of slight axial and radial movements until it is positioned against the platen roller.

Title: Communications system
Inventor: HAHNE ELLEN L
IPC: H04L12/28
Filed: 1990-06-28
Granted: 1996-12-17
Abstract: A potential transmission-access failing in the IEEE 802.6 protocol is remedied by the use of terminals that sense the activity level on the interconnecting communications lines.  In response to conditions that may give rise to such a failing, each terminal throttles its own transmission rate to improve the transmission capacity allocation of the protocol.  In one embodiment, the terminal that transmits over more than half of the slots in the round trip delay simply throttles itself to one half the slots when it detects that another terminal is transmitting or is wishing to transmit. In another embodiment, even a terminal that is transmitting over fewerthan half the slots in the round trip delay determines the number of unoccupied slots and throttles itself to transmit over not more than half of the number of available slots. In still another embodiment, a terminal wishing to transmit many packets casts a number of reservation bits onto the transmission channel to insure for itself some transmission capacity.  The number of reservation bits sent is equal to a fraction of the available slots.  In yet another embodiment, each terminal throttles itself to take no more than a specified fraction of the remaining transmission capacity.

Abstract: An apparatus and a method for creating a database wherein the data entry, such as a journal entry in accounting, is the canonical record can be implemented utilizing a microcomputer.  A plurality of data entries to be classified are separate records each comprised of one or more items having associated quantities ant an entry number serving as a pointer to the record.  Each item contains information including at least an item number or label and a quantity.  At least two item indicators are then generated for each of the item numbers.  A mapping function is applied to each data entry to assign the item indicators for the item numbers based upon the associated quantities.  The item indicators for the data entry are sorted into ascending numerical sequence and an n-dimension sparse matrix is selected where "n" is the number of items in the data entry. If the present combination of item indicators is new, a design record is created for the database based upon the sparse matrix and including the item indicators, the associated quantity sums, the total number of data entries summarized in the design record and a pointer (a chain of entry numbers) to the records of the data entry detail.  The quantities for the present data entry are added to the quantity sums and the entry number is stored in the pointer chain.  After all the data entries have been processed, a search routine can be utilized to review the various design records as desired.

Granted: 1996-08-27
Abstract: A dual component dispenser gun is provided for controlled dispensing of flowable dual component materials, such as adhesives, sealants and the like. The dispenser gun is designed for use with a dual component cartridge having dual barrels respectively filled   with   the   two   flowable   components,   in combination with a mixing nozzle through which the components can be mixed and dispensed.  The cartridge is  supported  on  top  of  a  main  pressure  cylinder adapted  for controlled connection to a pressurized fluid source, such as compressed air, for displacing a  power piston  in  a  first  direction.    The power piston is connected to a pair of flexible piston rods which extend through curved guide channels in a guide head and are connected in turn to a pair of piston plungers  receivable  into  the  cartridge  barrels  to dispense the dual components.  A pressure responsive retractor assembly is carried by the power piston and responds to disconnection of the fluid source from the main cylinder to retract the power piston and associated  piston  plungers  at  least  slightly  and thereby  eliminate drool of the flowable components from the mixing nozzle.

Title: Cell culture device
Inventor: BINOT PATRICK
IPC: C12M3/00
Filed: 1991-03-28
Granted: 2002-01-08
Abstract: A novel cell culture device for the production of metabolites as provided herein. The device includes a housing, and a cell culture space, within the housing.      Fresh nutrient medium inlet means and outlet means, are connected, in parallel, to a sheet of tubes forming a wall of the culture apace and which are in fluid communication with the culture space. At least a subset of open-ended permeable capillaries is arranged in a layer within the culture space. The open ends of the capillaries lead to external inlet gas means and to outlet gas means and are in gaseous communication with the interior of the capillaries. The capillaries are arranged at equal intervals so as to form, on one side of the sheet of tubes, one subset allowing a homogeneous distribution for gas exchanges with the cells. A spent medium outlet means is connected to a first micron sieve forming each downstream wall of the cell culture space, in order to ensure that the cells are confined while allowing said spent medium to leave. The sheet of tubes in connection with the fresh nutrient medium inlet means and the outlet means, are structured in a closed-loop circuit. The sheet of tubes is constructed so as to provide, when fresh nutrient medium is passing through the circuit, simultaneously a first flow of fresh medium through each of the tubes, from end to end, and a second flow of fresh medium which is perpendicular to the first flow, from the tubes to the cell culture space, through their permeable walls.
