Abstract: Ref. No.: P 40 41 136.2                                 A 39 Abstract In a metering and spray pump for liquid, low-viscosity and pasty substances, an elastic bellows (3) is arranged between two plastic housing parts  (1,  2)  that  are  telescopingly movable relative to one another, connecting them, wherein it [the bellows], acting as a discharge valve (18), has, at one end, a valve annular wall (15) that surrounds the generated surface (17) of an annular wall (8) made in one piece with the first housing part (1) in a sealing manner and such that it can be lifted off.  As a suction valve (58), said bellows (3) has, at its other end, a valve annular wall  (54)  which is in sealing and separable contact with the generated surface (43) of a valve seat (42) made in one piece with the second housing part (2) such that it can be lifted off, wherein the medium to be pumped is drawn into the bellows (3) through the said valve seat.   To guarantee high reliability of operation, especially [good] quality of closing at weak valve opening forces, where the quality of closing can be tested even in the dry state, with the smallest possible number of simple and easy-to-assemble individual parts, the valve annular wall  (15)  of the discharge valve (18) and the valve angular wall (54) of the suction valve (58), which [valve annular wall (54)] is provided with a closed front wall (57), are each in contact with conical or hemispherical generated surfaces (17), 43),  wherein both valve annular walls (15, 54) are connected to the bellows (3) both radially elastically and elastically movably in the axial direction.

Abstract: SOLID ELECTROLYTE TYPE FUEL CELL                  ABSTRACT OF THE DISCLOSURE       A solid electrolyte type fuel cell for generating electric power.  The solid electrolyte type fuel cell includes two plate-shaped solid electrolyte type fuel cell elements formed with a plurality of recesses and a gas supply member for supplying an electric power generating gas to the fuel cell.       The gas supply member is provided with gas supply openings for the electric power generating gas and arranged between the plate-shaped solid electrolyte type fuel cell elements so that the gas supply openings are opening in the recesses.  When the electric power generating gas is supplied into the recesses from the gas supply openings, the streams of the electric power generating gas impinge against electrodes exposed in the recesses so as to turn their flowing directions to cause the streams to flow along surfaces of the electrodes.          As a result, the temperature distribution in the fuel cell becomes uniform so that the electric power generating efficiency can be improved.

Title: Gas permeable well nozzle
Inventor: ENGEL JAMES D
IPC: B22D41/58
Filed: 1992-03-30
Abstract: GAS PERMEABLE WELL NOZZLE ABSTRACT OF THE DISCLOSURE         The invention is directed to a gas permeable well nozzle for use in a metallurgical vessel such as in a well block of a tundish, ladle or like vessel.  The well nozzle is generally cylindrical in shape and includes a gas  permeable  refractory  member  having  an  axial  bore therethrough.    The gas  permeable member  is preferably formed of a pressed and fired ceramic refractory material having a high resistance to molten metal erosion such as alumina, zirconia or magnesia, present either as a single phase or as a carbon bonded system.  A castable refractory member  is  positioned  around  the  outside  of  the  gas permeable  portion  and  defines  an  open  gas  annulus therebetween.    The  castable  portion  contacts  the  gas permeable portion to form upper and lower gas impermeable joints around the gas annulus.  A metal can is preferably positioned around the castable member and includes a gas fitting which communicates with a gas inlet channel formed in  the  castable  portion  to  permit  introduction  of pressurized inert gas therethrough.  The major refractory constituents of the gas permeable member and the castable member are preferably identical so as to provide matched thermal expansion rates and thus lessen the opportunity for thermal induced cracking along the gas impermeable joints between the two members.

Title: Studded footwear
Inventor: COLLINS DAVID R
IPC: A43C15/16
Filed: 1990-10-04
Abstract: It has previously been thought desirable when providing an internally screw-threaded socket (1) for use in studded foot-wear to provide each socket and a complementary stud (2) with complementary screw-threads with a small helix angle and many turns in order to maximise the frictional grip between the stud (2) and socket (1). The invention provides a multi-start thread requiring at most one and a half turns (560°) to achieve full engagement, Contrary to conventional thinking such an arrangement is workable and has advantages over the known single start-threads for studded footwear. Arrangements of sockets and studs with two-start threads and retaining means (14; 16; 17 and 19) to prevent unscrewing of the studs are disclosed.

Title: Arbitration among multiple users of a shared resource
Inventor: HOLT CRAIG S
IPC: G06F13/374
Filed: 1991-01-16
Abstract: Arbitration is performed among a plurality of users (12a-12n) for access to a shared resource in a system (10) of the kind in which the users (12a-12n) arbitrate by placing arbitration signals on a line (19) and subsequently comparing their arbitration signals with a signal appearing on the line (19), by providing the users (12a-12n) with independently operating clocks (18) and controlling the progression of the arbitration based on timing provided by the clock (18) of at least one of the users (12a-12n). The progression of the arbitration thus does not depend upon a single master clock, or upon synchronizing the individual user clocks (18).  Users that request access are assigned a first priority in the arbitration based at least on an access priority preassigned to the request for access and on whether the user is a member of a current group of users that is formed at a time during the arbitration when another group of users is empty, the current group including users that have been denied access as of that time; at least a portion of each user's arbitration signal is arranged as a multibit word having a value that represents the first priority, and each user that arbitrates for access places its multibit word in parallel on the path and determines whether it has won the arbitration by subsequently comparing its multibit word value with the value of a multibit word that appears on the path.
