Abstract: ABSTRACT               DIE SET FOR MAKING BADGES OR BUTTONS       The die set comprises a hollow die (24) having an internal forming portion (42) for supporting badge parts (10, 12, 14).  A ring (22) is engageable in the die by latching elements (30) which cooperate with elements (34) on the die.  The marginal edges of the badge parts are bent initially over a cylindrical member (28, Figure 8) received in the die and these edges are then formed by insertion of a pressure member (26) in the die.  A backing is then inserted in the die and a hammer member (20, Figure 11) is engaged in the die and folds back the badge part edges to secure all the parts together.  The latching elements engage by rotation to lock the ring and the die together axially.

Abstract: ABSTRACT          A method is provided for asexually propagating pine trees, preferably loblolly pine, by vegetative propagation.  According to this method, pine seedlings are hedged by severing the main stem and detaching the branches so that only one lateral branch is left intact and attached to the remaining main stem.  The hedged seedlings are main-tained under conventional growth conditions at least until elongated shoots having juvenile characteristics are ob-tained at the cut end of the main stem.  The elongated shoots are then severed from the main stem and rooted by conventional means.

Abstract: ABSTRACT            A METHOD OF MANUFACTURING METALS AND/OR GENERATING SLAG            Finely powdered oxide ore is introduced (at 17) in a reactor (11), possibly together with slag-formers, and treated in three zones in the reactor.  The material is preheated and possibly melted in an upper, oxidizing zone by the combustion of carbon monoxide and hydrogen gas from the middle zone below with a gas containing oxygen.  In a middle zone consisting of a slag bath, the preheated and possibly melted oxide material at least partially reduced by the simultaneous injection of carbonaceous material and/or material containing hydrocarbon (15, 16) and thermal energy supplied primarily by means of gas heated in a plasma generator (14).  Finally, the material is caused to sink into a lower zone at the bottom of the reactor, from whence it is tapped intermittently, together with the slag, through a tapping aperture (19).

Abstract: CHARGE INJECTION DEVICE    ABSTRACT OF THE DISCLOSURE          In charge injection apparatus comprising essentially a charge injector (1) and a fluid supply arrangement (2) for the charge injector, fluid to be charged is introduced into a mixing chamber (20) via a supply line (25) where it becomes mixed with a volatile fluid, such as a high vapor pressure hydrocarbon or a halogenated component supplied through line   (28). The resulting fluid mixture is introduced into the charge injector and, on emerging through the exit ori-fice (5) of the charge injector into ambient atmos-phere,    the volatile fluid volatilizes to form a blanket of gas of higher dielectric strength than that of the ambient atmosphere.   In this way, resistance to dielectric breakdown is increased which enables the charge injector to be operated at higher potentials than would be the case in the absence of the volatil-ized fluid, without dielectric breakdown occurring.

Abstract: Abstract The problem concerns the improvement of a drive and positio-ning system with regard to its setting characteristics when used as a servo drive which is capable of latching, the said system comprising a rotor which is faced with permanent mag-nets, and a stator which possesses two or more sub-windings, these sub-windings being connected to an electronic power-supply circuit which is controlled in order to effect cur-rent commutation, control being accomplished by means of magnetic rotor-position sensors.  The invention solves this problem by adopting a design wherein the stator is ironless, wherein its sub-windings (I, II), which are disc-shaped and lie in parallel planes, are arranged in a manner such that they overlap, generating a magnetic field which is enclosed by the sub-coils, this magnetic field lying essentially par-allel to the one which is generated by the permanent magnets, and wherein the rotor-position sensors (7) are in each case integrated into both sub-windings (I, II).  An advantageous electronic power-supply circuit is also specified, the pur-pose of which is to control the drive system, this circuit comprising first and second multiplier elements and, in addition, adder elements, these various elements being dedicated, one to another, in accordance with a prescribed scheme (Fig. 4).

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to an inspection apparatus for detecting the surface distortion in a sheet of material such as a sheet of glass, for example, and for indicating whether the level of distortion detected in the inspected sheet is unacceptable.  The inspection apparatus includes a light source mounted to direct a first beam of light toward one surface of the sheet at an oblique angle of incidence to cause a second beam of light to be reflected therefrom.  A light detector is mounted to receive the reflected beam and is responsive to a light pattern produced by the reflected beam of light for generating an output signal representing the width of the light pattern.  The width of the light pattern is a function of the surface distortion of the portion of the surface from which the beam is reflected.  A control circuit is responsive to the detector output signals for generating an actual distortion signal representing the amount of surface distortion in the inspected portion of the surface.  In the preferred embodiment of the invention, a plurality of individual actual distortion signals are generated and are utilized by the control circuit for generating an overall distortion signal representing the overall distortion in the inspected sheet.  The overall distortion signal is compared with a reference distortion signal which defines the acceptable level of surface distortion.  Based on the comparison, an indicator is provided for indicating whether the inspected sheet is unacceptable.

Abstract: AN OPTICAL LOCAL AREA NETWORK USING A COMMON OPTICAL CARRIER WITH SEPARATE USER ANGLE MODULATION            Abstract The present invention relates to a multiple-user communication system wherein one carrier source is shared by a cascade of users of the system. More particularly, the present communication system uses a single carrier propagating along the system's transmission medium onto which each user directly impresses the associated data or communication signal destined for another user preferably using either subcarrier angle modulation (phase or frequency) or TDM techniques for intensity or angle modulation. In the present system using subcarrier angle modulation, each user can either transmit or receive at a fixedly assigned or selectively assigned subcarrier channel, which is different from the subcarrier channel assigned to each of the other users. Where TDM techniques are used, the communication signal from a user can be directly impressed on the single carrier using intensity or phase modulation. With such communication system, amplifiers can be liberally used along the bus with no inter-modulation distortion since the amplifiers see a constant envelope signal. The use of amplifiers solves the problem of excessive signal loss incurred when multiple users tap into or out of, for example, an optical fiber bus.
