Abstract: PHF.79-521 ABSTRACT:           A generator provided with means for the com-pensation of deviations from the voltage which it sup-plies.  The generator is characterized in that a nega-tive feedback resistor is included in the emitter circuit of a transistor between whose emitter and collector branches said voltage appears, through which resistor a current flows which is supplied by another transistor whose current varies as a function of supply voltage variations.  The generator is in particular used for supplying bias voltages to logic circuits.

Abstract: ABSTRACT OF THE DISCLOSURE:           A device for determining the AC line voltage amplitude/frequency characteristic of an AC network, comprising a circuit for integrating an input signal, having a certain voltage amplitude and frequency, and re-presentative of the line voltage and frequency of the AC network. The integrating circuit repeatedly integrates the input signal to obtain an integrated signal proportional to the maximum voltage amplitude of the input signal and representative of the voltage amplitude/frequency ratio of this input signal. The device also comprises a circuit responsive to the input signal for repeatedly generating control signals defining an initial and end points of the integration of this input signal as a function of its frequency such that a phase angle between the initial and end points, and a phase angle between each initial point and an immediately preceding zero passage of the input signal, are at least substantially constant. An electronic switch is responsive to the control signals for controlling the respective initiation and termination of the integra-ting of the integrating circuit to provide integration intervals between respective initial points and successive end points. An output signal of the device is provided by a circuit responsive to the integrated signal, which output signal is by itself representative of the voltage amplitude/ frequency ratio characteristic of the AC line.

Abstract: ABSTRACT A constructional toy is disclosed comprising a plurality of nodal elements and a plurality of co-operating rod elements.  Each nodel element is substantially spherical and has a plurality of channels formed upon its peri-pheral surface, including a first channel encircling the nodal element so as to pass through the poles thereof.  At least four other channels are spaced about the peripheral surface so as to be intercepted by the first channel adjacent the poles of the nodal element.  The lips of each channel have inwardly project-ing beads thereon.  Each rod element comprises a shank having a connecting por-tion at each end thereof, the connecting portion including an annular groove and having a longitudinal cross-section of substantially the same configuration as the transverse cross-section of each channel.  When a connecting portion of a rod element is 'push-fitted' into a co-operating channel, it is held therein by virtue of the engagement of a lip bead within the annular groove of the connecting portion in such a manner that the longitudinal axis of the rod element is in substantial alignment with the geometrical centre of the nodal element.

Abstract: ABSTRACT OF THE DISCLOSURE           A bimodal electrophotographic apparatus and process which incorporates capabilities for making both positive and reversal copies.  One surface of a layer of a zinc oxide coated paper, or the like, is given an initial electrostatic charge.          The charged surface is then exposed to an image having light and dark areas for causing surface charge to dissipate, in varying degree depending on the amount of light striking the charged paper, in the exposure areas.  A charged toner is applied to the zinc-oxide-coated paper by a magnetic brush.  In the reversal mode, the brush has a bias potential.  The brush is formed by an aggregation of magnetic toner particles clinging to the outside of a cylindrical sleeve while magnets inside the sleeve rotate.  The toner collects on the paper to form an image depending upon where the charge is dissipated.  A paper supporting shoe having an electrically insulated structure is located beneath the coated paper, with the insulation in the area where it passes adjacent the magnetic brush so that no current can pass through the toner after it is deposited onto the coated paper.  Preferably, a pair of fuser rollers are electrically insulated so that when they come in contact with the surface of the coated material, after the toner is deposited thereon, they do not dissipate the image-caused charge.  The fusing rollers may also be given a bias corresponding to the bias on the toner, for the same reason.

Abstract: Abstract An induction heating system for heating an end length of a forging bar following the cut-off therefrom of a pre-viously heated and forged end length is arranged to bring the end length to be heated to a uniform temperature des-pite the existence of a residual hot end portion from the previous heat.  The heating system has an induction heating coil with a longitudinally extending axial passageway therethrough for receiving the bar length to be heated by insertion into a feed-in end of the coil passageway.  A stop member is positioned adjacent the open other end of the passageway to abut the forward end of the inserted bar so as to locate it wholly within the passageway.  Electri-cal circuitry is arranged to connect an AC power supply first to a partial portion of the length of the heating coil extending from the feed-in end thereof so as to heat the as yet unheated portion of the inserted bar end length to a temperature more or less corresponding to that of the residually heated endmost portion of the inserted bar length.  Thereupon, the electrical circuitry then connects the full length of the heating coil to the power supply so as to evenly heat the inserted bar length throughout its entire extent to the desired forging temperature.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention provides a novel water-swellable caulking material which is a composite body of stratified structure composed of at least one rubbery layer swellable in water comprising highly water absorbing resin dispersed in the matrix of a rubber and at least one rubbery layer not swellable in water integrally bonded together, which latter serves to resist the expansion of the former layer when swollen in water in the directions other than the direction perpendicular to the plane of the layers.  The inventive caulking material can exhibit unexpectedly excellent water sealing effect with easiness in handling in addition to the rapidity in water absorption by virtue of the structure thereof preventing the expansion of the material in the directions of length and width without decreas-ing the expansion in the direction of thickness.
