Abstract: ABSTRACT OF THE DISCLOSURE     A vehicle has a compartment joined to a carrier by springs.  An attracting magnetic device has a first part (e.g. a ferromagnetic travelling field stator) mounted on a roadway, and a second part (e.g. spaced permanent magnets forming a synchronous linear motor in combination with the stator) mounted on the carrier.  The two parts of the magnet device lie opposite one another to leave an air gap there-between and so to hold the vehicle in spaced relation to the roadway.  An additional force device is mounted to act be-tween the vehicle and the roadway and supplements the force of the magnetic attraction to make up the holding force needed to maintain the vehicle in the desired position rela-tive to the roadway.  Displacement means can displace the part of the magnetic device that is mounted on the vehicle to displace that part relative to the additional force de-vice to vary the width of the air gap and thereby vary the force of the magnetic attraction. And such displacement by the displacement means is caused by means responsive to variations in distance between the vehicle compartment and the carrier on compression or expansion of the springs.

Abstract: ABSTRACT OF THE DISCLOSURE A fastener for joining sheet material having aligned quadrilateral apertures includes a grommet and stud.  The grommet has a head with spaced side portions and an opening therethrough.  A pair of spreadable essentially parallel stems extend axially from the side portions on opposite sides of the opening and define a quadrilateral figure slidably receivable in the perforations.  The stud is attached at one end integrally in a limited area to the grommet within the opening and arranged, when severed from the head at the limited area, to move between the stem elements and to rotate thereby to spread the stem elements and lock the grommet in place within the aligned apertures.  The extremities of the stems form at their confronting sides converging cam surfaces terminating in confronting spaced apart bearing faces.  The cam surfaces are each disposed at an angle to an axial plane of the grommet.  The shank of the stud includes a stem spreading element having sur-faces which form a minor and a major width.  The shank with its major width oriented in a direction perpendicular to the aforementioned axial plane is moved axially between the bearing surfaces which are thereby spread apart. The stud is subsequently rotatable for alternate placement of the surfaces defining the minor width and those defining the major width in engagement with the bearing faces.

Abstract: 47,429 PARALLEL AC ELECTRICAL SYSTEM WITH DIFFERENTIAL PROTECTION IMMUNE TO HIGH CURRENT THROUGH FAULTS              ABSTRACT OF THE DISCLOSURE   In systems, such as aircraft electric power gener-ation systems, three phase AC generators are often operated in parallel when supplying power to load busses and differ-ential protection networks are utilized in each phase of each generator for detecting current imbalance between the phase conductor at the load and the neutral conductor of each phase.  In this invention there is provided voltage limiter means such as back-to-back Zener diodes across each of the current transformers related to the phase and neutral conductors which, in conjunction with the other portions of the differential protection networks: (1) prevents nuisance tripping on the occurrence of high current faults outside the differential protection zone (such as bus faults) due to normal variations of the current transformers, and (2) at the same time, provides differential protection for a gener-ator channel over the required range, generally from very low differential fault currents to the very high differen-tial fault currents.  The high differential fault currents will appear as high through current faults for the unfaulted parallel channels.

Abstract: ABSTRACT OF THE DISCLOSURE         A bicondylar joint prosthesis for articulating two portions of a natural or artificial human limb.  It comprises two pairs of coacting male and female condylar components of artificial material.  The male components consist of medial and lateral protuberances each engageable with a respective complementary female medial or lateral condylar component.  The lateral pair of condylar components are shaped to allow relative angular deflection of the two limb portions simultaneously about two axes.  The first or hinge axis passes in the medial-lateral direction through the common mean centre of relative rotation of the lateral condylar components and the second axis also passes through the said centre and lies in a plane substantially normal to the first or hinge axis. The medial condylar components are shaped to roll on each other about both axes.  The rolling motion about the second axis pro-duces angular deflection of the first or hinge axis in a plane sub-stantially normal to the general axis of the limb in extension.  The medial male condylar protruberance has a curvature about the mean hinge axis.  The co-acting female medial condylar component is constituted by a groove having a radius of curvature about the second axis.  The bottom of the groove is substantially flat or has a radius of curvature about the mean hinge axis which tends to infinity and is greater than the radius of curvature about the mean hinge axis of the male condylar protruberance.

In one embodiment, the helical thread-type means includes cooperating helical ribs and grooves on the electrode carrier and the forward interior wall of the inserter tube, and a plunger rod pushes the electrode carrier forwardly.  In the preferred embodiment, helical grooves are formed on a motion converter which carries the electrode carrier, and radially-inwardly projecting pins on the forward interior wall of a plunger tube engage the helical grooves; and stop means are provided for limiting forward movement of the motion converter, whereby depression of the plunger after the coil electrode has moved forwardly a predetermined distance will result in only rotary motion of the coil electrode.

The apparatus and method allow a film having tapered bosses with decreased cross-sectional areas leading to a perforation to be formed without use of expensive vacuum forming methods.             The invention discloses a film 10 being heated by a heating means 14 to a deformable state and being embossed on an embossing surface 16 of embossing roll 13 under pressure from the silicone rubber surface 33 of first pressure roll 15.  The film on the apex of the cone 26 on embossing surface 16 is removed to perforate the cone by perforating roll 17, which is a resilient hollow metal tube heated from a radiant heater mounted on the inside of the hollow metal tube.  The perforated film is then embossed a second time by the action of a second embossing roll 18 and then rewound onto a rewind roll.
