Title: Nail retaining strip
Inventor: STEFFEN MARKUS
IPC: F16B15/08
Filed: 1987-03-03
Granted: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE           A nail retaining strip for feeding nails into a fastening element driving tool where the nails are driven individually out of the tool by a drive piston includes guide bushings for the nails.  Adjacent guide bushings are separably interconnected by connecting webs.  The guide bushing extends in the axial direction of the nail shank and has axially and circumferentially-extending circular guide surfaces for supporting the nails within the muzzle bore of the driving tool.  The connecting webs extend radially outwardly from the guide surfaces so that the guide surfaces on adjacent guide bushings are in spaced relation.  The connecting webs retain the nails in the axial direction of the muzzle bore by engagement in a receiving recess in the bore located opposite a passage through which the nails are inserted into the bore.  Such axial retention permits complete utilization of the nail strip down to and including the last nail.

Abstract: ABSTRACT OF THE DISCLOSURE     A  flat  wire  conveyor  belt  comprising  a plurality  of  tractive  pickets,  a  plurality  of connecting cross rods and a plurality of bar links is disclosed.  Elongate openings in several of the wedge-shaped  segments  of  each  tractive  picket adjacent the outer edge define a gap between the connecting  rod  and  the  adjacent  surface  of the openings during straight and lateral travel of the belt.    Elongate  openings  in  the  remainder  of wedge-shaped  segments  are  in  contact  with  the connecting rod in straight travel.  Openings in the bar links define a gap between the connecting rod and  an  adjacent  surface  of  the  opening  during straight travel of the belt.  The remainder of the wedge-shaped  segments  thus  carry  a  substantial tractive load during substantially straight travel of  the belt,  the bar  links  carry a substantial tractive load during travel around lateral curves, and the wedge-shaped segments adjacent the outer convex edge of the belt never carry a substantial tractive load.

Abstract: VEHICLE RETARDER SYSTEM AND CONTROL            Abstract of the Disclosure A vehicle retarder system has a hydraulic retarder and a slipping friction brake operating in concert to retard the forward motion of the vehicle. The hydraulic retarder is an output driven device which is operable to absorb increasing energy as the vehicle speed increases.  The friction brake is normally a ratio control reaction brake for the lowest forward drive ratio of the vehicle transmission.  The brake has an additional apply piston which is operable to slippingly engage the brake whenever the hydraulic retarder is operable and the vehicle transmission is not in the lowest forward ratio.  The control system has a control valve which is operable to control the engagement pressure of the additional piston in a manner such that the friction braking effort is higher at low vehicle speeds.  This compensates for the lower effectiveness of the output driven hydraulic retarder. The control system is also effective to control the operation of the hydraulic retarder, the main piston of the reaction brake, cooling flow to the brake and cooling flow from the retarder.

Abstract: ABSTRACT      A continuous web of paper which may be longitudinally folded in half is drawn around a rotating cylinder which cuts the web into pre-determined suitable lengths.  Vacuum and air pressure means temporarily hold the severed portions of the web  against  the  cylinder,  but  at  an  appropriate  moment release the leading edge of the severed portion causing it to be lifted in its leading half away from the cylinder,  the trailing half being retained by suction against the cylinder. The lifted leading edge folds backward against the trailing portion  along  a  fold  line,  and  subsequently the  folded-together leading and trailing portions are released from the cylinder,  transported  away  from  the  cylinder  and  into  a stacking tray, for subsequent packaging.  The cut and folded sections of the web are, at all times, held under control by a vacuum in one or more cylinders or conveyor belts until the very last moment when they are discharged into a receiving and stacking tray.
