Patent EP-0020095-A1 (EP)
Inventor: WASHBURN WILLIAM J
IPC: F41A9/04
Filed: 1980-05-22
Abstract: A accumulator arrangement (10) for a machine gun has a handling conveyor (17) passing through a supply channel (16), a bypass channel (14), and a return- channel (18). The supply channel leads to a freed system (12) of a machine gun. At the junction of bypass channel and return channel there is connected to a return conveyor (46) leading from the feed system. A gate (24, 50, 52) is mounted at the junction of the bypass channel and supply channel operably between two positions, one position directing ammunition (58) on the handling conveyor onto a supply conveyor (44) leading to the feed system and a second position directing ammunition on the handling conveyor through the bypass channel via the return channel. Upon release of a trigger mechanism operably connected to the gun, the gate moves from its first position to the second position. The feed system continues its forward operation to clear itself of any live ammunition therein. The handling conveyor maintains a forward mode directing ammunition into the bypass channel. A reversing mechanism reverses the handling conveyor to retrieve live ammunition from the bypass channel to the supply channel after the feed system is cleared of all live ammunition. So the live ammunition intermediately accumulated in the bypass channel can be fed to the feed system during the next operation of the machine gun. 
     The accumulator arrangement and feed system might also be used for article handling systems in general which handle individual linkless articles other than ammunition in rapid sequence.

Abstract: Although known 6-phenyl-3(2H)-pyridazinone derivatives possess a strong anti-peptic ulcer activity, they do not all exhibit activity over long periods of time and can produce unfavourable side effects. These difficulties are now overcome by derivatives represented by the formula (I):
     wherein R', R 2  and R 3  independently represent a hydrogen atom, a halogen atom, a lower alkyl group or a lower alkoxy group; R' and R' independently represent a hydrogen atom or an alkyl group; m represents an integer of 1 to 3; n represents 0 or an integer of from 1 to 3; Z represents -CH 2 -, -0- or -S-; X represents -S-R 6  or -N"H-R', wherein R 6  represents a lower alkyl group and R' represents a hydrogen atom, a lower alkyl or a propargyl group, and the carbon atoms at positions 4 and 5 of the heterocyclic ring of the formula (I), to which R' and R' are bonded respectively, are joined by either a single or a double carbon-carbon bond; and acid addition salts thereof; with the proviso that where Z is -0- or -S-, the carbon atoms at positions 4 and 5 joined by a double bond and n represents an integer of 1 to 3. These compounds have therapeutical activity against peptic ulcers.

Des configurations d'acheminement de fil vertical et horizontal (3, 4, 5) sont tracees sur les lignes verticales et horizontales qui possedent la meme distance d'espacement que mentionne ci-dessus. Etant donne que les longueurs longitudinales et laterales de chaque cellule sont des multiples entiers de la distance d'espacement (d) dans la grille (10), les bornes de chaque cellule sont positionnees dans une plage correspondant aux tolerances du cablage.

IPC: G06F13/374
Filed: 1981-07-21
Abstract: A common bus architecture is disclosed which has truly distributed control. A plurality of bus interface units (BIU) are interconnected by the distributed system data bus (DSDB) which includes a clock line (4), a serial command line (CMD), a serial bus allocation line (BAL) and a two byte wide data bus (8). A central clock connected to the clock line which defines the message frame timing, is the only centralized "control" element in the system. Each BIU may in turn be connected to either one or several data processing units, an I/O port, or a bridge connecting to still another similar bus network. 
     By prior arrangement, several BIUs will establish a set of relative priorities, commands and corresponding data transfer operations. The BIUs share the DSDB in a time division multiple access mode which requires them to agree to a time divided allocation of the common bus based upon their distributed assessment of the relative priorities of their pending messages. When a processor serviced by a first (talker) BIU wants to transmit data over the DSDB to a processor serviced by a second (listener) BIU, a three stage priority contention resolution operation takes place to obtain an exclusive allocation of the DSDB for the desired data transmission.

Abstract: A fuel filler tube (24) is secured to an inside constructional member of a vehicle with its fuel inlet mouth portion spacedly received in a cup-shaped member (12) secured to a vehicle auter panel (10). An outwardly projected bumper member (36, 30b, 38, 38d) having a considerable size is mounted or formed on the fuel filler tube in the vicinity of the fuel inlet mouth of the tube. Thus, upon a vehicle collision inducing a considerable displacement of the filler tube relative to the cups-haped member, initial collision occurs between the bumper member and the cup-shaped member thereby suppressing the collision of the filler cap with the cup-shaped member.
