Abstract: PRODUCTION OF INSULATED ELECTRICAL CONDUCTORS            Abstract of the Disclosure:                Method and apparatus for forming an insulating layer of substantially constant diameter on an electrical conductor.  The layer is coated upon the conductor as a homogeneous mixture of fluid carrier and magnetically permeable particles and the coating operation takes place by passing the conductor upwardly through the fluid mixture and then upwardly and axially through a magnetic field.  The field resists the flow of particles through it, thereby permitting a certain thickness of the material to pass through the field and coat the conductor.  At least one annular magnet is used to create the field and when two or more magnets are used, these are axially in line with each other.                                  - i -

Abstract: ABSTRACT OF THE DISCLOSURE            There is disclosed a process for the production of molten pig iron or of steel pre-products from particulate ferrous material as well as for the production of reduction gas in a meltdown gasifier. A fluidized-bed zone is formed by coke particles upon the addition of coal and by blowing in oxygen-containing gas by nozzle pipes penetrating the wall of the meltdown gasifier. The ferrous material to be re-duced is introduced into the fluidized bed. In order to be able to produce molten pig iron and liquid steel pre-prod-ucts in a direct reduction process with a lower sulfur content than has hitherto been the case, without having to make any particular demands on the sulfur content of the coal used, the ferrous material to be reduced is supplied closely above the blow-in gas nozzle plane producing the fluidized bed. An arrangement for carrying out the process includes a meltdown gasifier in which charging pipes pene-trating its wall are provided in the region of the fluidized-bed zone closely above the plane formed by the nozzle pipes. The ferrous material to be melted as well as the dusts separated from the reduction gas and, if desired, fluxes containing calcium oxide, magnesium oxide, calcium carbonate and/or magnesium carbonate are introduced there-through.

Abstract: AN OPEN CENTER LOAD SENSING HYDRAULIC SYSTEM          Abstract of the Disclosure An open center, load sensing hydraulic system is disclosed which contains a primary work circuit and a secondary work circuit.  A fixed displacement pump is fluidly connected between a reservoir and both the primary and secondary work circuits for supplying pressurized fluid thereto.  The primary work circuit includes a control valve which regulates fluid flow from the pump to a primary hydraulic function and which includes a feedback mechanism connected thereto.  The secondary work circuit includes a manually operable control valve for regulating fluid flow from the pump to a secondary hydraulic function.  A priority valve is connected between the pump and both the primary and secondary work circuits and is movable to regulate the pressure to the primary work circuit. Pressurized signals from the primary work circuit are transmitted through a load signal line to the priority valve and are used to move the priority valve to a position which assures that adequate pressure is always available to the primary work circuit.  The system also includes a control valve for sensing pressure variations between the fluid discharged from the priority valve and the fluid present in the load signal line.  This valve prevents fluid flow out of the primary hydraulic function, via the load signal line, when the pressure of the fluid discharged by the pump is less than the pressure of the fluid in the load signal line and thereby essentially eliminates kickback from the primary control valve.

Abstract: Abstract of the Disclosure Digital circuitry performs arithmetic operations upon first and second binary coded decimal digit strings input thereto.  The digital circuitry provides for receiving and storing   first and second BCD digit, the digits having an arbitrary data type format.  The first and second data types are selected from the group of packed and unpacked data.  The cir-cuitry then performs the arithmetic operation upon the stored BCD digits to obtain a result data word which is made available in a data type format corresponding to a selected one of the input BCD digits.  In a particular embodiment, a plurality of the circuits can be operated in a digit slice structure.  The digit slice structure operates upon strings of packed, unpacked, and mixed data type arithmetic operands and provides, at its output lines, output data in a format corresponding to a selected input data type.  In particular a unique interconnection of the plural out-put lines of the circuitry enables the output data type to be packed or unpacked as desired.  The circuitry also provides for automatic selection of digits applied to the circuitry thereby relieving the operating environment from significant time con-suming and costly supervision.

Abstract: ABSTRACT OF THE DISCLOSURE           Described herein is a movable cart of the "push" type, adapted to carry various items of hardware or building material such as lumber, carpentry materials, plumbing supplies, and the like.  The cart comprises a base frame including a split level deck or platform member which consists of a rear deck member and a front deck member, the rear deck member being of slightly larger dimensions than, and positioned slightly above, the front deck member.  Both front and rear deck members are rectangular, and may be (and preferably are) provided with decking.  The base frame is provided with small wheels or casters for rollably moving the cart.  The cart also includes a pair of parallel upstanding members attached to the ends of the base frame and inclined slightly forwardly from the vertical, to the upper ends of which members is secured an open-ended tray member of rectangular outline, which projects forwardly a predetermined distance from the upstanding members and a connecting member joining their upper ends.  The split level deck construction of the cart is such that when the front of a first cart of this type is pushed against the rear of a second cart of the same type the two carts will "nest" together by virtue of the front deck member of the first cart sliding beneath the rear deck member of the second cart, thus enabling the carts to be stored in a minimum of floor space when not in use.
