Title: Mechanical anti-hangfire system
Inventor: BORHORQUES LUIS A
IPC: F41A7/08
Filed: 1980-05-28
Granted: 1984-11-28
Abstract: The protection system is for gunner, involving a feed with a firing mouthpiece and a breech block, together structure, a displacement device between breech block and firing mouthpiece. The system encompasses the feed-in of a projectile the locking of the breech block, the firing of the projectile, the unlocking of the breech block, the removal and ejection of the projectile casing, and the feed-in of a fresh projectile. A movable component allows the breech block during normal firing to be displacec relatively to the firing mouthpiece, a further component determines the degree of recoil as an indication for the right moment for reloading, whilst a stop unit connected to a probe can interrupt normal component function of the breech block.

Title: Method for detecting fluorescence
Inventor: FAY HOMER
IPC: G01N21/64
Filed: 1981-05-18
Granted: 1985-03-04
Abstract: Fluorescent materials such as certain metal ores are detected under ambient light conditions by observing the material through a gated aperture which is opened at predetermined intervals for periods of predetermined duration while simultaneously exposing the material to periodic pulses of fluorescent stimulating light. The frequency of the light pulse is synchronized with the frequency of the opening of the gated aperture so that the aperture is open for at least a portion of the period during which fluorescence is produced by the stimulating light pulse. Electro-optic goggles are a preferred type of gated aperture.

Title: Aluminum alloy foil for minus pole of electrolytic condenser
Inventor: ARAI GOOHJOOH
IPC: C22C21/00
Filed: 1981-09-30
Granted: 1985-12-26
Abstract: Electrolytic capacitor cathode foils are produced from a continuously cast plate of aluminium alloy contg. 0.08-0.45 % Cu and 0.005-0.04 % Ti. The alloy is pref. prepd. using aluminium of at least 99.7 % purity and pref. containing a max. 0.3 % total of Fe and Si impurities. The presence of Cu, together with the use of continuous casting, results in a high density, unifrom distribution of pits, without excessive wt. redn., and on etching the foil, the capacitance of the foil is improved. Cu also increases the mechanical strength of the foil. The Ti prevents cracks from developing in the continuously cast plate and improves the foil strength, without reducing the capacitance.

Title: Apparatus for cooling a hot product gas
Inventor: PAPST GERO
IPC: F28C3/02
Filed: 1985-07-18
Granted: 1994-03-05
Abstract: An apparatus for cooling a hot product gas, the latter is passed through a tubular zone. The product gas contains particles which, on entering the tubular zone, are tacky, but lose their tackiness through cooling in said zone. Within said zone a cooling gas flow forms a gas wall, which prevents contact between the product gas or the tacky particles contained therein, and one of the fixed walls in the tubular zone. Thus within an outlet connection (2) forming the tubular zone is provided an anular insert (3), which forms a gap (4) with the outlet connection. A cooling gas is blown into this gap counter to the flow direction of the product gas. At the end of the insert, this cooling gas is deflected by the product gas and flows within the insert in the same direction as the product gas and protects the inner wall of the insert from the latter. This product gas is cooled to such an extent by the action of the cooling gas that the particles in the product gas have lost their tackiness at the outlet-side end of the insert.

Title: Alternator for automobile
Inventor: KURIHASI YASTAKA
IPC: H02K9/06
Filed: 1987-03-13
Granted: 1990-08-09
Abstract: The alternator includes two cooling fans, rear and front, rotatable with the rotor shaft disposed on opposed sides of the rotor. These fans are received in front and rear brackets, respectively. The brackets have inlet ports and outlet ports through which drafts of cooling air are to be drawn in and out of the inner cavity of the alternator through rotation of the fans, attaining cooling of necessary parts e.g. a stator winding, rotor exciting winding, rectifier diode, etc. One fan on the front side has a suction capacity greater than that of the other fan on the rear side, causing a negative pressure differential between the two suction sections of cooling fans. This results in an additional axial flow of cooling air directed from the rear to the front which contributes to improvement of cooling efficiency for the rectifier diode and rotor exciting winding.

Hydraulically full fluid flow through the vessel (6) uniformly contacts the wafers with the fluid and results in improved and more reproducible prediffusion cleaning, rinsing, etc. A mechanism (40) imparts plug-flow to a treatment fluid flowing into the vessels (6). One plug-flow imparting mechanism includes a flow-expansion input element (40) and a fixed helical flow-diverting surface (136). Another mechanism incorporates a rotating flow diverting surface (252).
