Abstract: Although the conventional continuous riveting machine was able to use exclusively a special blind rivet having a longer core-stem than that of the standard type, the continuous riveting machine according to the present invention is able to use the standard blind rivet and also able to recover separately torn core rivet stems and a blind rivet-holding belt made of plastic material enabling the supply of blind rivets in series. When a lower piston 600 descends in a jaw cylinder 400, a nose piece 620 integrated in one piece with the lower piston 600 also descends while bending downwardly plastic upper and lower tabs of the blind rivet-holding belt, and holding the blind rivet. Torn-core-stems are absorbed and stored in a torn core rivet stems storing case installed on the upper portion of the jaw cylinder by applying vacuum air absorbing force generated in a vacuum ejector.

Abstract: An apparatus for securing a binder to the spine of a cover with rivets. A pair of rivet supports holding two rivets in a support position over a pair of anvils is movable between release and support positions with a biasing spring returning the rivet support to the release position. A drive shaft moves the pair of rivets in a downward vertical direction terminating in a downward stroke so as to drive the plain ends of the rivets through the cover spine and the binder. Drive linkage connected to a horizontal rotatable drive bar activated by a lever activates the drive shafts to a limited lowered position and a raised position. The anvils receive the plain ends of the rivets and make the plain ends of the rivets into second heads upon termination of the downward stroke of the drive shafts whereby the rivets secure the binder and the cover spine. Keepers prevent lateral and transverse movement of the binder and and cover.

Abstract: Penetrating nozzles are disclosed for first penetrating standard commercial and residential building materials to form a relatively small entrance hole or opening and subsequently delivering water to the area to cool off superheated gases. Different water dispersion attachments may be used, including a spiral or screw-type attachment for providing a mist or fog to the area or straight stream nozzles for directing a stream of water in directions either parallel to the axis of the nozzle or at an angle 90.degree. thereto. The nozzles include a protector cap at the leading axial end thereof which is provided with a tip suitable for battering the surfaces or barrier and punch a hole through it. The protector tip is retained on the tubular attachment until the protector tip has penetrated the barrier and has been placed on the other side, at which time the application of water under pressure to the elongate dial causes the protector tip to be cast off or ejected.

Abstract: Braking expectation control, based upon manual selection by the driver of the vehicle plus automatic activation (including override of the manual selection) operates to give the following motorist information concerning the type-of-stop. Blinking yellow lights warn of an easy slowdown such as occurs when coasting with the accelerator free. Red stop warning lights burn brightly for a standard stop, as is the case for currently manufactured vehicles. For the panicstop, however, all rear lights come on--red brakelights, red or yellow turn signals together as hazard warnings, hazard lights if separate from the turn signal lights, backup lights--followed by blinking yellow for a continuing warning. The automatic control takes sensor inputs for accelerator-free, foot-on-brake, brake pressure at two levels, stop and panicstop, and includes a timer to determine whether the brake activity is a tap or a more serious stop or panicstop.
