Abstract: ABSTRACT   The invention relates to a method for producing lead having a sulphur content beneath about 2%, from sulphur-containing oxidic lead raw materials conta-minated with zinc and/or other readily oxidized elements, by smelting the materials in a furnace in which the furnace contents can be agitated. When practicing the method, the lead raw materials are charged to the furnace together with iron-containing fluxes and solid reduction agents. The charged materials are heated under agitation, to form a lead phase and a slag phase. The amount of reduction agent charged is selected so that at least all th lead contained in the furnace is reduced to lead metal and the amount and composi-tion of the fluxes are selected so that a terminal slag is obtained in which the sum of the iron and zinc present is 30-40% and so that the slag has a content of 15-25% of both SiO2 and CaO + MgO.       Lead raw materials, fluxes and reduction agents are suitably introduced in a plurality of charges, with intermediate moderate heating, prior to commenc-ing the smelting process.

Abstract: ABSTRACT       The invention is particularly concerned with controlling the two stage regeneration temperatures of the RCC residual oil cracking unit below 760°C  (1400°F)  by effecting a first stage regeneration with direct injection of water in an oxygen lean atmosphere to product CO rich flue gases under temperature conditions restricted not to substantially exceed 732°C  (1350°F) preferably less than 732°C (1350°F) thereby partially regenerating the catalyst. The partially regenerated catalyst is withdrawn and directly cooled with boiler feed water to produce steam in an external catalyst cooler before passing the catalyst to a second stage catalyst regeneration for contact with an oxygen rich atmosphere restricted not to exceed 760°C (1400°F) and preferably maintain less than 760°C  (1400°F).   The catalyst regenerated by this technique comprising residual coke less than 0.25 wt% is passed to a riser conversion zone for catalytic cracking residual oil feeds.

Abstract: READ/WRITE HEAD POSITIONER ARRANGEMENT      Abstract of the Disclosure The present invention employs, in a preferred embodiment, a pair of pulleys, one of which is fixed and the other of which is movable and each of which has substantially the same diameter.  The pulleys each have an axial aperture which holds a bearing arrangement including a shaft.  Mounted across the two shafts is a pair of plates which are interconnected and therefore act together as a rigid body.  The rigid body, or rigid member, is movable in a rotary fashion.  In addition there is a flexible band member which loops a substantial section of the movable pulley and, in a preferred embodiment, is disposed to come in frictional contact with the movable pulley and the fixed pulley.  The ends of the band are secured to the fixed pulley and are held in tension.  Accordingly, as the plates (the rigid body) are moved in a rotary fashion around the center of the fixed pulley, the movable pulley is moved, relative to its associated shaft, in a counter direction in response to the friction force between the band and the movable pulley.          Hence, in the preferred embodiment, the movable pulley effects a curvilinear translation.  A read/write head assembly is secured to the movable pulley and in response to the curvilinear translation, the read/write head assembly is moved radially across a plurality of tracks of a magnetic disk.  In this way, the change in yaw, or skew, between the read/write head and the tracks on the magnetic disk is held to a minimum.

Abstract: PREPARATION OF ORTHO-AMINOBENZOTRIFLUORIDE ABSTRACT       This invention relates to a process for the preparation of ortho-aminobenzotrifluoride (OABT) from benzotrifluoride (BTF). The process provides an overall route employing non-isolation of intermediates which can be run smoothly and which results in the preparation of OABT in high yields with less contamination. This process includes a catalytic halogenation step in which BTF is converted to meta-halo BTF and other mono and di-halo isomers of BTF followed by nitration in the same reaction vessel under conditions which do not favor nitration of the di-halo isomers of BTF to produce a mixture which predominates in 5-halo-2-nitro BTF. In the final step the 5-halo-2-nitro BTF present is reduced and hydrodehalogenated with H2 in the presence of a cata-lyst to form OABT. Recyclable BTF is also obtained from the final reaction.

Abstract: ABSTRACT An electromagnetic printing hammer device including a permanent magnet having a pair of electromagnetic pole-faces spaced apart from each other by a gap.  A hammering element formed of a permanent magnet at least in one portion thereof is located in the gap for movement in a plane parallel to the pole-faces.  The hammering element exerts a force of impact on the back of a type as a thrust is applied thereto when a pulse current is passed through the electromagnet, the hammering element being supported for linear movement in a direction in which it exerts a force of impact.  The invention enables the time during which the hammering element moves in reciprocatory movement to be shortened and allows the speed at which the hammering element responds to the magnetism to be increased.  The advantages offered by the invention include improved performance testified to by an increased number of prints produced per unit time, and a minimized loss of the energy of impact attributable to the linear movement of the hammering element, thereby greatly increasing the practical value of the device.

Abstract: METHODS AND APPARATUS FOR                 FORMING GLASS ARTICLES         Abstract Methods and apparatus for forming glass articles such as  bottles  and  the  like  utilize  flows  of pressurized  cold cryogen vapor that are introduced into mold cavities which are being used to mold glass  articles.   The  cold cryogen vapor hastens cooling and solidification of the articles so that the time during which the articles must be retained in their molds is significantly reduced.  Reductions in mold retention times enable the apparatus to be operated at increased speeds, whereby its  productivity  is  significantly  increased.   Productivity increases of  15 percent  and often more  can be achieved at relatively  low  expense.   The  use  of  cold  cryogen  vapor introduction into mold cavities is applicable to a variety of glass  molding  techniques  including  press  molding  and  blow molding.  Cold cryogen vapor introduction can be used in staged molding procedures,  for example in operations where a hollow blank or parison of glass is first press-formed in a roughing mold, and is then blow-molded in a finishing mold to assume its final  form;  in  such a staged procedure,  cold cryogen vapor introduction may be used in either or both of the roughing and finishing  stages  to  expedite  solidification  and  to  permit increased productivity.  In preferred practice the cold cryogen vapor is nitrogen gas that is released from a container of liquid nitrogen.  Cold cryogen vapor may be mixed with flows of cooling and/or blowing gases for delivery with these gases into mold cavities.   In preferred practice, cold cryogen vapor is delivered into the mold cavities without being mixed with other flows of cooling and/or blowing gases.
