Abstract: ABSTRACT      The manufacture of non-returnable packages for e.g. milk is frequently carried out by the conversion of web-shaped, laminated packing material to a tube, filling of the tube with milk, and sealing and forming to filled packing containers of the desired, e.g. parallelepipedic, shape.  For the forming, which is done by means of external forming devices, the contents are made use of as a holder-up for the forming device pressed-on from the outside, so that the desired shape can be achieved without creasing or other deformations.     The abovementioned forming principle works less well if the packing containers are not completely filled, but have a certain air space, so-called headspace.  The proportioning of the contents also becomes uncertain and the desired accuracy of volume cannot always be achieved.  These difficulties are overcome in that a sealed off part of the packing material tube is pressurized with the help of gas during the forming process, so that the internal back pressure required during the forming is obtained, independently of the quantity of contents.  The method also permits an accurate proportioning of the contents either by continuous feed at a controlled flow rate or by discontinuous feeding in portions.  The invention also relates to an arrangement for the realization of the method.

Abstract: LAWN MOWER FRICTION DRIVE MECHANISM                     ABSTRACT OF DISCLOSURE           A friction drive mechanism is provided for machinery such as a lawn mower wherein a driven wheel is provided with an outer ring that slips upon initial engagement with a driving disc.  The coefficient of friction between the inner surface of the ring and the driven wheel is selected such that when slip-page occurs, it occurs at this interface and not between the outer surface of the ring and the driving disc.  Upon initial start-up when the driven ring first engages the driving disc, the ring will slip relative to the driven wheel to avoid a sud-den transmission of torque to the ground wheels.  The coeffecient of friction and the normal force between the inner surface of the ring and the driven wheel are selected such that gradually the relative velocity between the ring and driven wheel decreases to zero and the ring no longer slips on the driven wheel but rotates at the same speed as the driven wheel.

Abstract: ABSTRACT OF THE DISCLOSURE A railroad measuring, gauging, and spiking apparatus uses a closed servoloop arrangement to provide accurate rail gauging.  An LVDT sensing arrangement uses three rail feeler wheels to sense the rail gauge immediately adjacent to spiking guns on the apparatus.  The output from the LVDT sensor is fed into a signal processing circuit which compares this signal with the desired track gauge in addition to calibrating various analog signals.  A gauger control circuit comprises a microprocessor chip which raises and lowers a gauger mechanism and causes the gauger mechanism to track an error signal output by the signal processing circuit until the error signal is equal to zero.  The hammers of the spiking guns are interlocked to receive an OK TO SPIKE signal from the microprocessor such that the spiking can not take place until the circuits indicate that the rails are properly gauged.

Abstract: OPTICAL WAVEGUIDE MANUFACTURE          Abstract of the Disclosure Optical waveguide having a fused silica core and a fluorine doped silica cladding is made by heating a cylinder of silica in fluorine, the cylinder initially having an outer annular particulate or porous region which is dried by the fluorine and into which fluorine diffuses to lower the refractive index of the silica when fused.  The cylinder is made by depositing particulate silica onto a mandrel, drying the silica in chlorine, and heating the silica to desify it.  Further particulate silica is deposited and is when heated in a fluorine-containing gas to dry, fluorine diffuse, and sinter the porous outer part of the silica.  The resulting tubular silica preform is heated to collapse the tubular preform into a rod from which optical waveguide is drawn, the waveguide having a fluorine doped silica cladding.  In one alternative the silica cylinder is made by depositing onto a mandrel a first layer of relatively dense silica followed by a second layer of less dense particulate silica so that fluorine diffuses preferentially into the lower density material.  In another alternative, the silica cylinder is made by depositing particulate silica directly onto d high purity fused silica rod without sung a mandrel, the deposited silica then being dried and subjected to fluorine diffusion.

Abstract: REGULATED VOLTAGE AND APPROXIMATE CONSTANT POWER             FOR THERMAL PRINTHEAD                 Abstract of the Invention Electrodes 1a through 1n are driven by operational amplifier 4 under control of a reference current source 25.  The voltage at each electrode 1a through 1n is monitored by diodes 19a through 19n so that point 21 is set at that of the lowest electrode voltage.  A current source provides equal currents through diode 23 and the conducting one of diodes 19a through 19n.  The potential of control input 5 is therefore that of the lowest potential of all of electrodes 19a through 19n.  Feedback through resistor 27 produces a differential amplifier system in which V2 is set by source 25.  The output of amplifier 4 and the magnitude of resistors 15a through 15n are selected so that the nominal voltage on line 13 is reduced by one-half across the resistor 15a through 15n.  This approximates constant power to ribbon 2.          The voltage regulation and constant power each act to limit power dissipation at the ribbon surface.  This reduces debris at the printhead.

Abstract: ABSTRACT     An overhead electric conductor comprises a central tubular metal core, at least one layer of helically wound bare metal wires surrounding the core and, loosely housed in the bore of the core, at least one optical fibre element.  The optical fibre element comprises a flexible tube of elongate transverse cross-section in which is loosely housed an optical fibre ribbon structure and which is resiliently set in such a form that the central longitudinal axis of the tube follows a path of smoothly curved undulations, the axes of curvature of which lie parallel to one another and normal to the axis of the tube.  Should a tensile force applied to the overhead conductor be transferred to the loosely housed optical fibre element, the flexible tube of the element will tend to straighten in a lengthwise direction against the action of its resilient set thereby to reduce any tensile force that might otherwise be applied to the optical fibres and, when the tensile force is removed, the tube will return under the action of its resilient set towards its original form.

Abstract: Abstract Inverter In an inverter for the production of the voltages of a polyphase system, connections between each phase conductor and the terminals of a direct voltage source arrangement are closed and opened through controllable switches.  The zero voltage, the crest voltage and at least one intermediate voltage lying between these voltages are tappable at the direct voltage source arrangement; for the staircase shaped approximation of a half sine wave, each phase conductor is connected to the zero voltage for a first time span, to the intermediate voltage for an immediately following second time span, thereafter to the crest voltage for a third time span, thereafter to the first intermediate voltage for a fourth time span and to the zero voltage for an immediately following fifth time span, which is repeated with alternating voltage signs; in order that no damaging countercurrents flow into the direct voltage source arrangement in the case of a phase displacement between current and voltage occurring by reason of a capacitive or inductive loading, two phase conductors are connected at the same time during the second and the fourth time span to the terminal delivering the first intermediate voltage.
