PURPOSE:To make automation possible with a simple installation to make economical manufacture possible by applying an ultrasonic-bonding method. CONSTITUTION:After a bottom stopper 3 made of thermally plastic synthesized resin is fixed and inserted into the lower end part of a tube 2 which is filled with lead powder 1, the resulting body is inserted into a receiptor jig 5 having a supersonic wave ...

PURPOSE:To form groups of electrode plates in group holders by repareting the processes of separating one electrode plate in an electrode plate holder, inserting it into the mentioned group holder, separating one separator in a separator holder, and inserting it into the holder. CONSTITUTION:An anode plate 1 and a cathode plate 2 are supplied to an electrode plate holder 5 by an electrode plate su...

PURPOSE:To eliminate any occurrence of speed-reducing shock or noise by making a clutch gradually cutting into a disrngaged state when a forward-- backward switch lever is selected in the opposite direction for switchback travel, and varying the extent of throttle opening so as to keep engine speed constant for this while. CONSTITUTION:Engine speed during the travel of a vehicle is detected by a s...

PURPOSE:To keep off any deterioration of a catalyzer as well as to secure a fundamental traction control function in an alternative manner by prohibiting or checking any engine power reducing control for traction control in a state that temperature in the catalyzer goes beyond the specified value, and shifting up the gear of a transmission. CONSTITUTION:A traction controller detects a wheel A with...

PURPOSE:To keep off any large slip in a driving wheel to be predicted of its occurrence at time of large opening starting with certainty by reducing a control starting threshold value for driving torque control relatively at time of the large opening starting when body speed is less than the specified value and accelerator opening is more than the specified value. CONSTITUTION:A control unit UTR p...

PURPOSE:To secure quick switchback travel and deceleration being relatively less in a sense of incompatibility by controlling a braking operation with a relationship between time and car speed till the car speed comes zero from a point of forward-backward switch lever selecting time at time of the switchback travel. CONSTITUTION:Each detecting signal out of a car speed detecting sensor 1, an accel...

The formation efficiency of pasted positive plates of a lead-acid battery is greatly enhanced by providing in situ a layer of lead dioxide (PbO2) on the pasted plate surfaces prior to formation. The PbO2 layer is preferably formed by treating the surfaces of the plates with an ozone-enriched gas to convert a portion of the poorly conductive positive active precursor material (nPbO.PbSO4) to electr...

A method for the direct gaseous reduction of iron ore to sponge iron at an elevated temperature suitable for hot briquetting, wherein a hot reducing gas is circulated upwardly through a descending body of iron ore and a make-up reducing gas stream is added to the circulating gas stream. A sponge iron product having a predetermined desired degree of carburization in the range 0.5% to 4% is obtained...

Plate assemblies (10, 20) for lead-acid batteries (100) according to the present invention comprise a plurality of positive and negative electrode plates (1a, 1b, 2a, 2b) which are alternately interspaced, and a plurality of separators (3) sandwiched in between each pair of said positive and negative electrode plates (1a, 1b, 2a, 2b). The knack of this invention lies in the electrode plate constru...

The invention relates to a continuous blood centrifugation cell, comprising an outer rotating container (1) which accomodates a body, rigidly connected therewith and coaxial thereto and formed by two walls (2,3) joined at the ends, the outer container (1) carrying at its top portion a stationary joint (9) comprising conduits (10,11,12) which are coaxial to the stationary joint (9), the outer condu...

Coacting die cylinders (10, 12) with one cylinder (10) having a cutting blade (14) and the other cylinder (12) having an anvil surface (16) which when rotating cooperate to cut a blank from a web of low density material. The blade and the anvil surface (16, 22) are tapered in opposite axial directions so that the clearance between them can be readily varied and adjusted by moving the cylinders (10...

A traction control system for a motor vehicle of the type having a front pair of wheels (8R, 8L), a rear pair of wheels (12R, 12L), a set of brakes (22R, 22L, 24R, 24L) provided one on each wheel of the vehicle, and brake control means (20) for individually controlling the braking forces applied by the brakes to the front and rear pairs of wheels. In order to offer a choice between two or more dif...

Dewatering of sludge (esp. clarification sludge) is in a solid casing screw centrifuge with a sieve portion. After pre-dewatering in the clarification portion of the centrifuge, the sludge is post-dewatered in the sieve portion. Pressurised gaseous medium is applied from the interior onto the sludge layer in the sieve portion region. A solid casing screw centrifuge for carrying out the process has...

Sieve blockages may occur in fully mantled worm-drive centrifuges when removing water from very fine grained clear sludges with a relatively high proportion of capillary-bound moisture. The novelty is that the sieve section has a larger radial distance from the centrifuge drum shaft than the radial distance of the solid outlet, and that the sieve section has an axial radius from the solid outlet w...
