Abstract: ABSTRACT OF THE DISCLOSURE         A building construction system that permits the erection of a modular-skeleton structure type building in a very short time utilizing relatively unskilled labour.  The construction system utilizes a skeleton-type structure consisting of vertical metal profile posts which extend from the foundation to the horizontal roof girders in a single unit of uniform cross-section.  The vertical profile posts are pierced in the vicinity of the base by at least one wire cable which extends parallel to the external walls of the building and which is passed through lower-lying holding devices.  The holding devices are fixed in the foundation.          Tensioning devices are provided by means of which the wire cable can be tensioned in a downwardly-directed manner whereby pressure downwardly on the foundation is exerted on the vertical profile posts.

Abstract: ABSTRACT: "Optical coupling device".     The coupling device serves to couple an end (1) of a light-conducting fibre to an optical transmitter device (3) and an optical receiver device (5). The receiver device (5) comprises a light-collecting element (17) arranged opposite an end face (13) of the fibre end (1) and provided with an opening (19). The transmitter device (3) comprises a transmitter element (7) arranged opposite the opening (19) behind the light-collecting element (17) with a transmitter lens (9) for focussing light emitted by the transmitter device onto the end surface (13) of the fibre end (1). In order to obtain a robust construction which can be composed in a simple manner, a transparent body (21) optically coupled to the fibre end (1), the light-collecting element (17) and the transmitter element (7) is arranged between the end face (13) and the light-collecting element (17), this body having reflecting side faces (27), as a result of which substantially all the light emanating from the fibre end strikes the light-collecting element (17).

Abstract: ABSTRACT A circuit is provided for resetting a digital logic circuit, such as a digital counter.  A switch 16 provides a first signal when a predetermined condition has occurred. A flip-flop 24 provides an output reset signal when the flip-flop is in a first state, in response to the first signal.  The digital logic circuit to be reset 32 is coupled to the output of the flip-flop 24 for receiving its output reset signal.  Feedback means 34, 36, 38 are coupled from the digital logic circuit 32 back to the flip-flop 24 for providing a signal to put the flip-flop into its other state whereby its output reset signal is termi-nated.

Abstract: ABSTRACT          A shock absorber  (10)  has a rebound stop assembly (22).  The rebound stop assembly (22) rests upon a shoulder (30) fixed to a piston rod (16).  The rebound stop assembly (22)  includes an elastomeric ring  (24)  interposed between two  collars  (26) and (28)  forming  an  annular  chamber  (74) therebetween.  At the end of the rebound stroke of piston rod  (16),  the  rebound  stop  assembly  (22)  is  axially compressed between the shoulder (30) of piston rod (16) and the rod guide (18) until the elastomeric ring (24) deforms to abut the  inner wall  (64)  of the working cylinder.  As the elastomeric ring deforms, the annular chamber decreases in volume.  A restrictive passage (71) allows a restrictive flow  of fluid  therefrom.   An  additional  chamber  (70)  is formed which is in restrictive fluid communication through the passage (71) with section (68) of rebound chamber (20). Further compression of the stop assembly (22) decreases the volume of both chambers (70 and 74), and causes restrictive fluid flow out therefrom through the passage (71) into the section  (68)  of rebound chamber  (20).  The compression of the  elastomeric  ring  and  the  restrictive  fluid  flow provides  additional  damping  at  the  end  of  the  rebound stroke.

Abstract: ABSTRACT OF THE DISCLOSURE Protective  relay  apparatus  for  detecting  the direction or distance to a fault from the measuring point on an ac electrical power transmission line using current and  voltage  deviation  signals.   The  deviation  signals represent  the  changes  induced  by  the  fault  from  the steady-state  pre-fault  magnitudes.   Trajectories  are plotted on an X-Y plane using the voltage deviation signal as the X-axis coordinate and the differentiated current deviation signal multiplied by the line reactance to the balance point as the Y-axis coordinate.  Due to the use of the differentiated current deviation signal, the trajec-tories are straight lines.  The threshold boundaries for determining the distance to or direction of the fault are time-varying  lines  of unit slope representing the pre-fault voltage at the fault point.  For a fault outside the balance point, the trajectory lags the threshold boundary; for a fault at the balance point, the trajectory is always equal to the balance point voltage; and for a fault inside the balance point, the trajectory always leads the thresh-old boundary.

Abstract: Abstract of the Disclosure Ignition-Assisted Fuel Combustion System Conventional direct injection internal combustion engines will not completely ignite and burn relatively lower-cetane-number fuels such as 100 percent methanol or ethanol because the fuel spray injection pattern usually cannot carry or propagate a flame to all the injected fuel which is typically made up of individual fuel streams which are separated by pockets of fuel-deficient intake air.         The present fuel combustion system includes a fuel ignition-initiating device such as a glow plug and apparatus for interconnectedly contacting and continuously bridging all of the individual fuel streams with an auxiliary cloud of well-atomized fuel. In this manner, a flame initiated by the fuel ignition-initiating device is rapidly and completely propagated via the auxiliary cloud of fuel to all the individual fuel streams.

Abstract: ABSTRACT OF THE DISCLOSURE     A slide fastener slider includes a pair of parallel spaced wings each having a generally W-shaped front edge extending between a pair of flanges extending along the opposite lateral edges of the wing across a neck interconnecting the wings to define therebetween a substantially Y-shaped guide channel.  The front edge has a pair of outer portions respectively disposed adjacent to the flanges and projecting forwardly beyond a pair of planes extending respectively between a front end of the neck and respective front ends of the flanges.  Each of the wings has a pair of sloped interior guide surfaces extending respectively along the outer portions of the front edge and facing forwardly of a slider body of the slider.  When a pair of rows of coupling elements is introduced into the guide channel in a tilted condition, the tilted individual coupling elements are substantially brought back into their normal position as their leg portions slide along the sloped guide surfaces on one of the wings prior to arrival of their coupling heads at the front edge of the other wing.  The slider is capable of sliding smoothly along the coupling elements even when the coupling elements are tilted with respect to the general plane of stringer tapes of the respective fastener.

A bearing housing is supported on the bearing to orbit therewith, the bearing housing having an arm extending to a platen support and extensibly and pivotably connected to a portion thereof.  This orbiting of the bearing housing influences motion of the platen sup-port in accordance with the angle of the cone described by the second axis of the drive shaft.  The platen support is made of a resilient material and carried by the housing on legs extending to a base portion, which legs have a low moment of inertia in the direction of in-line sanding, and a high moment of inertia normal to the direction of in-line sanding, so as to be disposed to motion in the in-line sanding path only.  A platen is attached to the platen support by a key and key slot, one on each, which permits assembly when aligned and retains the platen to the platen support when rotated.  Resilient paper clamps are provided which cooperate with grooves in the upper surfaces of posts on the platen, to retain sand paper to the platen.

The breech blocks for the respective barrels are joined together via a cam on the breech block, such that the two breech blocks together constitute a cam mechanism which permits movement of the other breech block toward and away from the first breech block transversely of the barrels, and that the two breech blocks, during repeater-action of the weapon, move together and in parallel in the longi-tudinal direction of the barrels.  The interconnected breech blocks thus together and synchronously lock the two breech blocks in their forward  positions.
