Title: Process and device for spraying a liquid intermittently, especially a lubricant suspension to be sprayed under high pressure
Inventor: HEUSSER WILLI
IPC: B05B15/00
Filed: 1991-03-20
Abstract: ABSTRACT OF THE DISCLOSURE      A lubricant suspension is sprayed intermittently under high pressure by spray nozzle (4).  Spray nozzle (4) operates like an excess pressure valve, by it opening automatically with the input pressure of the suspension exceeding a threshold value pressure and closing automatically in the case of the input pressure falling short of the threshold value pressure.  The suspension is conveyed, without the interposition of a shutoff device, directly by pneumatically driven pump (2) to spray nozzle (4). The pump output pressure is maintained at a pause pressure in the pauses between the spraying intervals, is increased to the spraying pressure to spray the liquid, and is again lowered to the pause pressure at the end of the spraying interval.  The pause pressure in this case is calculated so that it is just insufficient in value to open spray nozzle (4).  The shutoff element subject to abrasion, previously necessary, between the pump and the spray nozzle becomes unnecessary by the pump pressure control according to the invention.  The operating safety is significantly increased and the spraying starts immediately without delay when the pump pressure is increased.

Abstract: In a magnetic key operated lock a slide member carries a plurality of wheels which carry magnet pins.  The position of the pins forms part of a code of the lock.  The wheels are caused to rotate by insertion of a key having a code for unlocking the lock and moving the slide member.  As the slide member moves, one of the pins which is repelled by the key abuts a stop which thus causes the respective wheel, and so the other wheels, to rotate.  By having wheels of two different sizes, the smaller wheels can be made to rotate more than once before a code is repeated.  An abutment is formed by pressing a tang from stationary wall in the lock. Variations in which a single wheel may have more than one abutment associated with it so that a magnet pin can be used to change the code when it is in more than one position, and a wheel may pins of different polarities with respect to the key are also disclosed.

Title: Casting of modified al base-si-cu-ni-mg-mn-zr hypereutectic alloys
Inventor: ROGERS KEVIN P
IPC: C22C21/02
Filed: 1990-08-09
Abstract: An aluminium base-silicon hypereutectic casting alloy with Si 12-15 wt.% has (a) elements A in wt.%, Cu 1.5-5.5, Ni 1.0-3.0, Mg, Fe each 0.1-1.0, Mn 0.1-0.8, Zr 0.01-0.10, Zn 0-3.0, Sn, Pb each 0-0.2, Cr 0-0.1, Si modifiers Na 0.001-0.01 and/or Sr 0.01-0.10, B(elem.) 0.05x, Ca 0.03x, P 0.05x, others 0.05x each (x = max.); (b) at least one of elements X, namely, Cr, Mo, Nb, Ta, Ti, Zr, V and combinations thereof, with-without Al, each of which form stable nucleants such as carbides, borides, nitrides, phosphides and combinations thereof, subject to the exclusion of AlB  in the presence of modifier Sr, (with which it reacts, with detriment to Al-Si eutectic modification). Each element X is present in wt.% 0.005-0.250; (c) at least one of elements Z, namely, Fe, Mn, Cr, Co, Li, Na, K, Rb, Cs, Ca, Sr, Y, Ce and other rare earth lanthanides and combinations thereof. Sr when used alone ranges 0.11-0.40. The remaining elements vary in terms of those selected, examples of which follow in wt.%, namely, Fe 1.5-2.0, Mn 1.0-2.0, Cr 0.5-1.0, Co 0.5-3.0, Na 0.1-0.4, Rb 0.5-2.0, Ca 0.9-2.0, Y, Ce, other rare earth lanthanide metals 0.5-3Ø The balance of the alloy is aluminium and incidental impurities, subject to the exclusion of Ti solely for X and Sr solely for Z. Elements Z are added for forming intermetallic phases, (e.g., Al2Si2Sr, Cr4Si4Al13), which form early during solidification and thus promote the nucleation of primary Si, which in turn promotes nucleation of the Al-Si eutectic, when the temperature drops below the Al-Si eutectic solidus, thus enhancing castability. The levels of elements X and Z may exceed predetermined respective levels in the alloy, because they function differently, either alone or when also present as A constituents. The final microstructure is predominantly an Al-Si eutectic matrix, in which any primary Si present is uniformly dispersed.
