Abstract: COMMUTATOR FOR A MINIATURE ELECTRIC      MOTOR     ABSTRACT OF THE DISCLOSURE     The commutator comprises three conductive sectors  2  which are maintained against a cylindrical insulating core 4 by an insulating ring 3.  Cut out from the rear end portion of each sector is a terminal 11  which defines two tabs 12  projecting axially  at the rear end of the sector.  Each pair of tabs straddles a parallelepipedic projection 5  of the core 4.  The three sectors are maintained radially and axially in position by the ring 3  which comprises an annular portion 15  from which extend three claws 16  in the longitudinal direction, the claws being clipped behind a flange 6  which projects from the core.  In this way, it is possible to mould the core and the ring 3  from a thermosetting material and to improve the maintenance of the sectors 2.

Abstract: ABSTRACT OF THE DISCLOSURE      The high-speed seal is a two-part metal-to-metal type seal that, in its initial application, acts as a conventional resilient O-ring.  As the seal begins to operate, a separate O-ring, retained within a seal gland channel formed in the body of a primary metal seal, provides an initial seal.  As the seal continues to function over a length of time, the separate O-ring retained within the seal gland in the ring wears away and metal-to-metal contact begins to be made.  Thus, the seal gradually converts from a standard O-ring type of seal to a lapped-in metal-to-metal seal during operation of the bit.

Abstract: SEGMENTED SPACER RING          ABSTRACT          Apparatus is disclosed for Making sheet-plastic articles, such as lids  for  disposable  drinking cups,  by  vacuum forming.  The invention provides  spacers  that  fit into the holes in the stripper  plate of the apparatus for the purpose of matching the size of  the hole closely to that of the  die  impression.   The spacers are flanged and in three segments,  the joins between the  segments being so arranged that two of the segments can be  first placed in the hole,  their flanges being entered into  a groove  in the  hole,  then  the third  is  located in  the hole and manoeuverd  radially  outwards  until its  flange  too is located in the groove. The segments are retained in place with a  spring  ring.   The segmented  spacers can easily be inserted at arm's length and by feel alone. The spacers are  themselves  radially thin so  that  the holes in the stripper plate can be packed tightly together.

Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed are cylinder lock arrangements which include a rotatable cylinder plug provided with recesses for guiding in axial direction blocking bars which cooperate with the cylinder housing to prevent in a blocking position thereof the rotation of the plug.  The blocking bars are formed with blind bores which in a releasing axial position of the bars communicate with a key channel.  The blind bores accommodate segmented pin tumblers which are controlled by control recesses on a lateral wall of a key so that upon the insertion of a correct key the separation planes of the segments of the pin tumblers coincide with the separation plane between the blocking bar and the cylinder plug.  The key for the lock of this invention has a profile defined by alternating longi-tudinal ribs and longitudinal grooves whereby the crest regions of the ribs are formed with the control recesses arranged at different levels in accordance with the segments of the pin tumblers.

Abstract: ABSTRACT          The processes of the invention comprise depositing onto a foamable or non-foamable support, in a first zone, a coating or print containing at least one first polymerisation initiator and, in a second zone which can optionally partially encompass the first zone, a coating based on a crosslinkable monomer containing at least one second polymerisation initator, at least two of the initiators being different and being triggered either by different effects or by one and the same effect but by different spectral zones.  The coatings are subjected to a pre-gelling and, at least locally, a graining operation, a polymerisation of the first zone so as to fix its appearance, and a gelling which, by causing fluidisation of the coating, causes the disappearance of the grained appearance in the non-crosslinked zone and may also cause expansion and thermal crosslinking.         The invention is particularly applicable to the production of wall coverings and floor coverings.

Abstract: METHOD AND APPARATUS           FOR WINDING SEAT BELT THEREOF           ABSTRACT OF THE DISCLOSURE      A seat belt winding apparatus with a rotation detection unit, for detecting a rotation of a belt winder shaft, and a driving unit, controlled by a detection signal from the rotation detection unit so as to apply a winding force to the belt winder shaft.      When the seat belt is pulled by passenger and a buckle is coupled with a tongue, the driving unit is controlled so that a rotational position of the belt winder shaft in a winding termination state is stored in a storage unit as a reference rotational position, thus establishing a correspondence between a reference rotational position and a count in the storage unit.      In the belt fastened state, when the rotational position of the belt winder shaft is shifted from the reference rotational position, the shifted rotational position of the belt winder shaft is compared with the reference rotational position.  The belt winder shaft is driven by the driving unit in accordance with the comparison result so as to return the belt winder shaft to the reference rotational position in the belt fastening state.  Meanwhile, when the rotational position of the belt winder shaft is shifted from the reference rotational position by the pull-out operation of the seat belt in the condition that the seat belt is not worn by the passenger and the tongue and buckle are not coupled, the winder shaft is driven only in a winding direction so as to return to a reference rotational position in the retracted state.

Abstract: ABSTRACT OF THE DISCLOSURE   Disclosed is a thixotropic flame inhibitor for a rocket propellant grain including an organic thixotrope in amounts from about 5 parts to about 30 parts into HTPB liquid polymer in amounts from about 70 parts to about 95 parts by stirring at elevated temperatures.  After cooling the mix-ture to room temperature, appropriate quantities of di- or polyfunctional isocyanates and cure catalysts are added to promote cure at room temperature.  Fine particulate matter may also be added to increase viscosity.  The resulting for-mulation is a room-temperature curable, thixotropic mixture which will not flow under its own weight when applied to wettable non-horizontal surfaces in appreciable thicknesses, and which, when cured, is suitable as an inhibitor for com-posite solid rocket propellants.  Thixotropy may be controlled by the level of organic thixotrope in the for-mulation while viscosity may be adjusted by the level of particulate filler; these parameters determine the allowable thicknesses from one-coat applications.

Abstract: ABSTRACT         A method of making a fastener from a sheet of material characterized by the steps of forming opposed offset circular openings in the material.  Opposed circular head end portions are formed surrounding the openings. Opposed offset elongated prong portions extend from the opposed periphery of the head end portions.  The prong portions are lanced to form inner and outer prongs.  The inner prong is displaced out of the plane of the surface of the outer prong to facilitate separation of the prongs.  The periphery of the circular openings is displaced out of the surface of the material to form a sunburst.  The stock between the opposed prong portions is removed and the completed fastener is also removed from the material thereby forming each fastener with a circular head end portion having only one elongated prong portion extending therefrom.
