Abstract: 6875     INVENTOR:    RUDOLF HELLER and IWAN KAHN CAN          INVENTION:   RADAR REELECTOR FOR AN ARTILLERY SHELL                    ABSTRACT OF THE DISCLOSURE                      A body which can be axially incorporated at an artillery shell comprises a functional or operational element constructed as a radar reflector. A sleeve element is arranged at such functional element. This sleeve element is rotationally symmetrical about a lengthwise axis and is intended to be attached to the artillery shell. The functional element and the sleeve element are constructed as one piece or integrally. At the inside surface of the sleeve element there are formed in a turnably symmetrical or rotationally symmetrical manner beads, fins  or claws or the like. The inner surface of the sleeve element is provided with an adhesive layer formed, for instance, of corundum powder contained in a synthetic resin. At the outside surface of the sleeve element there is arranged a fuse cord, the detonation of which produces a form-locking or positive connection of the sleeve element with the ordnance projectile or shell.

Abstract: METHOD FOR FABRICATING IMPROVED COMPLEMENTARY METAL OXIDE SEMICONDUCTOR DEVICES            Abstract of the Disclosure Disclosed is a process for a CMOS integrated circuit having polysilicon conductors of a single con-ductivity, single impurity type.  After forming the conductors they are covered by an oxidation and diffu-sion mask consisting of a dual layer of silicon dioxide and silicon nitride.  Then, source and drains of the p-channel and n-channel transistors are formed.  Next, an implantation or diffusion barrier is grown over sources and drains.  The oxidation and diffusion mask over all the conductors is then removed and they are all doped simultaneously using a single type impurity.          The process may be used to additionally form polysilicon resistors by initially doping the polysilicon to a low level of conductivity.  After forming the con-ductors and resistors they are covered by the oxidation and diffusion mask.  Then a resistor mask of either silicon nitride or polysilicon is formed over the resis-tors to protect them during the high conductivity doping of the conductors.

Abstract: ABSTRACT OF THE DISCLOSURE Improved flame retardance is imparted to high molecular weight aromatic polycarbonate resins by selecting appropriate fluorinated diphenols and incorporating them in homopolymers or copolymers.  The fluorinated diphenols have at least one fluorinated alkyl or fluorinated aryl group upon the methylene carbon atom positioned between the two phenol ring structures. The polycarbonates having improved flame retardance are made from fluorinated diphenols and halogen-containing carbonate precursors.  Copolycarbonates having improved flame retardance are derived from the fluorinated diphenols and non-fluorinated diphenols.  The flame retardant polycarbonates may be used in films and molded articles where improved resistant to flame is desirable.

A guide plate mounted on the base member has an aperture through which the head extends and a first disc guiding surface surrounding such aperture, and a positioning plate is mounted on the holding device and has a second disc guiding surface which, in the loaded position, is in parallel, spaced confronting relation to the first disc guiding surface.  When a cartrige is operatively disposed, the guide and positioning plates extend into the second openings in the cartridge walls so that the first and second disc guiding surfaces position the rotated flexible disc therebetween in the region of the head.

Abstract: ARITHMETIC UNIT FOR USE IN   DATA PROCESSING SYSTEMS                    Abstract of the Invention A data processing system using unique procedures for handling var-ious arithmetic operations.  Thus, in floating point arithmetic mantissa cal-culations the system uses a novel technique for inserting a round bit into the appropriate bit of the floating point result wherein a look-ahead carry bit generator stage is used for such purpose to reduce the overall mantissa calculation time.  Further, the system utilizes unique logic which operates in parallel with the floating point exponent calculation logic for effect-ively predicting whether or not an overflow or underflow condition will be present in the final exponent result and for informing the system which such conditions have occurred.  Moreover, the system utilizes a simplified tech-nique for computing the extension bits which are required in multiply and divide computations wherein a programmable array logic unit and a four-bit adder unit are combined for such purposes.

Abstract: A B S T R A C T               PRESSURE-DIFFERENTIAL METHOD FOR    SLEEVE-TO-TUBE JOINING           Method and apparatus for joining a sleeve to a tube wherein a sleeve is inserted within such tube and joined to the tube by means of an internal heating device which is inserted into the sleeve for bonding the sleeve to the tube.  The portion of the sleeve to be joined is then sealed and the portion of the sleeve to be joined is internally pressurized.   Once  the  sleeve  has  been  so pressurized, the heating operation is initiated.  In the case of welding,  the molten weld pool under the arc is continuously  driven  by  the  internal  pressure  gradient toward the external tube.  In this manner the arc force is cushioned by the molten pool at all times thus preventing the weld arc from piercing through the sleeve.
