Abstract: A Pope reel for winding a running paper web into a paper roll on a paper machine. The web is wound on a webwide king roll, which web wraps around the king roll on part of its circumference. A magazine holds a number of winding drums, each of which serves as a winding core. A pair of swivel levers pick up an individual winding drum and transfer it into its winding start position on the king roll. The winding drum with the paper roll being wound migrates along a guideway, and moves away from the king roll up to a delivery position for the finished paper roll. A second king roll is provided, which king roll is powered and is forceable down on the paper roll.

Abstract: A wide angle rear view mirror assembly for a motor vehicle has a supplemental optically flat wide angle mirror element mounted in a frame which in turn is mounted on the main rear view mirror assembly of a motor vehicle in juxtaposition with the main frame of the main rear view mirror assembly. The wide angle rear view mirror assembly is an after market device in one embodiment and is adapted to be mounted directly on the main mirror element of the main rear view mirror assembly, but can also be integrally built into the housing of the main rear view mirror assembly so as to constitute a feature of the automobile as manufactured. Either way, the wide angle rear view mirror assembly substantially increases the driver's rear view angle of vision utilizing an optically flat mirror, and also has provision for changing the vertical position of the angle of reflection of the wide angle mirror to accommodate different driving circumstances which affect what the driver sees in the wide angle mirror.

Abstract: Multi-channel transmission systems make great demands on the adjustment of the local oscillators in order to minimize carrier frequency variations on the transmission and reception sides. There are prior art processes and arrangements in which the local oscillators are adjusted by means of a synchronism word. The prior art processes and arrangements, however, have the drawback that the oscillators cannot be adjusted accurately enough. The present invention overcomes this drawback in that, in addition to the known synchronism symbols, other synchronism symbols are used and the synchronism symbols are evaluated with increased spectral resolution.

Abstract: A thermal transition section for introducing a high temperature cracked process gas into a quench exchanger having an inlet end comprising inner and outer concentric pipes connected to a closure ring to define an annulus between the pipes and an interior exchanger surface having an inside diameter. The transition section has a metal outer wall extending from a downstream end connected to the closure ring to an upstream end connected to a metal transition cone. The transition cone is connected at an upstream end to a line for supplying the process gas. The downstream end of the inner sleeve has an outside diameter matching the inside diameter of the interior exchanger surface. A precast, pre-fired single-piece ceramic insert substantially fills the annulus between the outer wall and inner sleeve. By using the ceramic insert, particularly a relatively long insert, thermal stresses are reduced and coke formation in the annulus is inhibited.

Abstract: Immortal avian T lymphocyte cell lines which produce and secrete immune lymphokines are disclosed. These cell lines may be produced from T cells recovered from fowl which have been hyperimmunized in vivo. The activated T cells are first exposed in vitro to a mitogen effective for secondary stimulation thereof, and then virally transformed to produce an immortal cell line. When cultured in vitro, the cell lines produce and secrete immune lymphokines which may be administered to fowl to increase their resistance to infections.

Abstract: A method and circuit arrangement for controlling the position of a rotor of rotary motor or a linear motor, e.g. a stepper motor, synchronous motor or the like, has at least two stator windings and a rotor with salient poles, wherein an actual value of the rotor position, e.g. the angle of rotation or the displacement of the rotor, is determined and compared to a desired value of the rotor position, with the exciting current that flows through the stator windings to move the rotor being modified in dependence on a determination of the inductance of the stator winding. The inductance is determined by superimposing the exciting current with a periodic measuring current that has a higher frequency than the operating frequency of the motor so as to prevent the measuring current from influencing the excitation of the stator winding, and by measuring the reactive voltage drop caused by the measuring current across the stator winding.

Abstract: A surgical implement particularly useful for implanting a prosthetic valve in an excised annulus includes a manually grippable handle, and a suture retainer carried by the handle and having an outer face carrying a coiled spring whose coils define an annular array of slits each having opposed yielding surfaces for receiving and releasably retaining sutures between selected coils. Optimum spacing of the sutures according to the shape of the excised annulus is attained by providing reference ribs between selected coils of the spring, and also by making the outer annular face of the suture retainer of substantially the same shape as that of the excised annulus. Embodiments are also described including an illuminating device for artificially illuminating the working area. Also described is a method of implanting a prosthetic valve in a quick and efficient manner using such an implement.

Abstract: The procedure for manufacturing fireproof crucibles for steel-processing ladles, in which aluminum deoxidation is carried out for the total quenching of liquid steel, is such that a monolithically hardening fireproof mass with a proportion of silicon dioxide is placed between the inside wall of the ladle and a reusable plug that is installed therein. After the plug has been removed, the ladle is put into use again, at which time a layer that contains alumina builds up on the hot side of the fireproof crucible and a highly sintered layer of greater hardness forms behind this. It is intended that a procedure such as this should simplify the reestablishment of the fireproof lining when the limits of use are reached, in view of the use of a layer that contains alumina and the highly sintered layer located behind this on the inside wall of the crucible.

Abstract: A secure read only memory in which an external address of (n-m) bits is applied to an address controller which converts the external address into an n bit internal address which is applied to a read only memory to obtain data stored in the read only memory at the address locations. The address controller includes detector circuits for detecting improper accesses to the memory. In response to an improper access to the memory, the memory controller will produce an improper access signal which improper access signal is used to terminate operation of the system or to modify the address so that the data produced in response to the external address has essentially no directly reproducable relationship to the actual address of the memory location of the random access memory where the data is stored.
