Abstract: "Method for the manufacture of metal packaging cans, and a semi-product in the manufacture of such cans"               ABSTRACT OF THE DISCLOSURE      In the manufacture of metal packaging cans metal sheet is deep-drawn and ironed to form a seamless tube having a bottom in one-piece therewith, and the tube is cut transversely to remove excess material at the end remote from the bottom.  This forms a cylindrical body and bottom of a two-piece can.  To minimise waste of material and to make possible the manufacture of a thin-walled three-piece can, the method includes  cutting the deep-drawn and ironed tube transversely at at least one location intermediate the bottom and the end remote from the bottom so that, from the tube, there are formed a cylindrical body and bottom of a two-piece can and at least one cylindrical body of a three-piece can.  Suitably, the tube is shaped by the deep-drawing and ironing so as to have a lesser wall-thickness at regions corresponding to the side-walls of the cans and a greater wall-thickness at regions which correspond to the flange portions of the cans.

Abstract: STATIONARY FEED MIXER            ABSTRACT OF THE DISCLOSURE    A stationary feed mixing apparatus includes a hammer mill for grinding the main ingredients of a feed ration prior to delivery of the main ingredients by a transfer auger to a mixer.  An electronic scale continuously weighs these ingredients as they are introduced to the apparatus.  A plurality of hoppers containing micro ingre-dients discharges micro ingredients upon a vibrating weighing conveyor device which is suspended by an elec-ironic scale so that the amounts of micro ingredients are constantly weighed prior to the discharge of the micro ingredients into the transfer auger.  The micro ingredients and main ingredients are premixed in the transfer auger prior to final mixing in the mixer.  Display units con-stantly display the weights of the micro and main ingredients, thereby permitting accurate control of the amount of the respective ingredients in each batch of feed ration produced.

Substituted quinolines are used as active extractant, in particular  alkyl substituted 8-hydroxyquinoline.  Gold is precipitated either by hot water,or by hydrogen after a cold water wash.  Palladium remains in the organic phase and is precipitated by more severe hydrogen reduction.  Platinum (and other precious metals) is stripped into the aqueous precipitant or wash, and can be recovered by hydrogen reduction (in stages).  The organic phase is not degraded providing acid is washed out before any hydrogen reduction, and can be recycled.

Abstract: LOCK MECHANISM FOR CLOSURE MEMBERS                    ABSTRACT       A lock mechanism for a closure member, such as a sliding door.  The mechanism comprises a housing for securement to the sliding door.  A locking slide member is slidingly guided in the housing.  The slide member has a locking element to engage and disengage with a keeper member secured to the frame of a door opening adjacent the sliding door.  A slide activating rotating knob is rotatably retained in the housing for limited rotating displacement therein.  A slide dis-placing pin is secured to the rotating knob and offset from the central rotating axis of the knob.  The slide member has a pin receiving slot which coacts with the pin whereby limited rotation of the knob causes dis-placement of the pin to frictionally engage the slide in the slot to cause limited sliding displacement of the slide between a locked and unlocked position.  The pin and the slide also coact, when in the locked posi-tion, whereby to provide positive interlocking to pre-vent displacement of the slide by force applied thereto.

Abstract: IMPROVED CAN END WITH RETAINED TEAR STRIP                  Abstract of the Disclosure An end structure for an easy opening container includes a rivet formed in a pour panel defined by a non-continuous scoreline.  Upon rupture of the scoreline by a tab, which is affixed to the panel by the rivet, both the tab and pour panel are retained on the end wall.  The scoreline may include a region of minimal residual in the region which is initially popped and regions of increased residual along the length of the scoreline in the direction of the fracture.   The scoreline forward and adjacent to the rivet is of a configuration which includes changes of direction rather than being a smooth continuous curve and cooperates with the stepped scoreline to reduce blow-off.  Also provided is a coined region radially outward of the rivet and the panel radius to create slack such that when the container is pressurized, the lifting end of the tab is forced downwardly.          Associated with the coined region is a localized coined panel radius which controls the location of the possible end buckle to reduce scoreline fracture due to buckle.  Provision is made to reduce laceration and an improved ring-pull tab acting as a Class 2 lever is disclosed.

The  vehicle includes  a driving motor,  a steering motor,  a driving motor chopper, a steering motor chopper, a speed detector, an  offset  (misalignment  away  from  the  guide  line) detector, a main CPU, etc.   Since detected offset values are directly feedbacked to the main CPU through a steering control  interface  and  the  steering  motor  chopper  is directly controlled by the main CPU through the steering interface; it  is  possible  to  eliminate  other  CPUs conventionally provided for turning on or off both the choppers,  separately.   Further,  since the duty ratio of the steering motor chopper is controlled by taking into account  various  factors  such  as  offset values,  offset increment  values,  vehicle  speeds,  steering  correcting directions, etc., it is possible to stably correct vehicle steering misalignment at high response speed even when the vehicle is travelling at high speed along the guide line.
