Abstract: ABSTRACT OF THE DISCLOSURE      The present invention relates to a method for utilizing a unique multi-chambered conduit insert for converting a single chambered conduit into a multi-chambered conduit.  In particular, the conduit insert includes a plurality of cooperating longitudinally extending walls defining a plurality of parallel spaced apart coextensive chambers.  The outer wall of each chamber which is adjacent the inner supporting surface of the single chambered conduit has a configuration wherein, if the outer wall contacts the inner conduit surface when the conduit insert is inserted within the conduit, such contact is line-to-line contact.  This construction results in minimal contact of the insert with the interior wall of the existing conduit and enables the multi-chambered conduit insert to be fed into the existing conduit with the expenditure of minimal energy.  In the method of the present invention, two individual conduit inserts are placed in back-to-back relationship to form an insert assembly which is subsequently inserted into the single chambered conduit.

Abstract: ABSTRACT          The disclosure relates to automatic guns in which there is included an apparatus for increasing the rate of fire of the gun.          The breech mechanism of the gun is controlled by means of recoil move-ments which arise on discharge of the gun and by an operating cam and spring member included in the mechanism.  Two case ejectors are disposed to arrest the breech block in the region of total recoil position of the breech and to hold the breech block in the open po-sition in order to make for ramming-home of a new round.  In the arrested position of the breech block, the ejectors are exposable to the new round during its ramming cycle.  A portion of the kinetic energy inherent in the round is transmitted to the ejectors which, in such an instance, may accompany the round and release the breech block so that this is actuated towards its closed position by the spring member.  The operating cam is movably disposed at least when the breech is located in the region of its total recoil position.          The spring member may, in this manner, begin to actuate the breech block on its movement towards the arrest position at an earlier stage than has hitherto been possible.

Abstract: SYNCHRONOUS FM DIGITAL DETECTOR       Abstract of the Invention A system for determining angular rate of rotation of a body about a rate axis. In one arrangement, the system comprises first (10) and second (12) accelerometers, movement means and processing means. The first and second accelerometers have their sensitive axes (16, 18) parallel to a sensing axis that is in turn perpendicular to the rate axis. The first and second accelerometers are adapted to produce first and second output signals (a1, a2), each output signal having a frequency corresponding to the acceleration experienced by the respective accelerometer along its sensitive axis. The movement means includes means (68) for producing a periodic movement signal and means (14) responsive to the movement signal for periodically moving the accelerometers along a movement axis perpendicular to the rate and sensing axes, such that each output signal includes a periodic Coriolis component. The processing means includes means (75) for producing a reference signal that defines one or more first time periods during which the Coriolis components have one polarity and one or more second time periods during which the Coriolis components have the opposite polarity. The first and second time periods together span one or more complete periods of the movement signal. The processing means further comprises means (71, 72) for determining, for each output signal, a phase value representing the difference between the phase change of the output signal duringthe first time periods and the phase change of the output signal during the second time periods. The processing means further includes means (80) for determining from the phase values a value representing the angular rate of rotation of the body about the rate axis. In a second arrangement, a single accelerometer is periodically moved along the movement axis.

Abstract: ABSTRACT OF THE DISCLOSURE   An electrofusion coupler sleeve for use in connecting together two plastics pipes by fitting the ends into opposite ends of the sleeve and passing an electric current through a resistance heater embedded in the sleeve adjacent its inner surface to fuse together the pipes and the sleeve, incorporates visual indicating means for indicating if the electrical energy supplied has been adequate for proper fusing. The indicating means takes the form of a blind bore extending into the sleeve from the exterior towards the interior. When, in use, the heater is energised, if the electrical energy supplied has been adequate For proper fusing, the softened flowable plastics material is forced, by the pressure produced by heating and fusing, to rise within the blind bore and project from the outer surface of the sleeve. The sleeve may comprise an inner plastics layer of a colour contrasting with that of the outer layer, so that, if fusing has been adequate, the contrasting material of the inner layer projects, from the blind bore, above the material of the outer layer.
