Abstract: An axle making method and apparatus for forming a unitary tubular axle blank with an I-beam section along an intermediate axle portion and with a bifurcated axle end for supporting a wheel spindle by ball joints. Inward deformations are formed in side walls of the intermediate axle portion to form the I-beam section by apparatus including a pair of punches with opposed forming projections between which the blank is received. Apparatus for forming the bifurcated axle end incorporates cooperable female dies and male punches with complementary work surfaces for forming the projections from a notched axle blank end and with edge work surfaces on the punch for axially upsetting webbed side walls extending between the projections in order to maintain the wall thickness of the webbed side walls at least as great as the wall thickness of the intermediate axle portion.

Abstract: An overload indicator particularly adapted for use with driving and driven components of a meat processing system conveyor to indicate when an overload condition takes place. A frangible member of the indicator is preferably embodied as a shear pin that normally connects the driving and driven components and includes an internal gas chamber which is communicated with the environment as the pin fractures in shear due to overloading. Pressurized gas supplied to the gas chamber of the shear pin decreases in pressure as the pin fractures and this pressure decrease is sensed to indicate the occurrence of an overload condition. A conduit for supplying the pressurized gas to the gas chamber of the shear pin preferably includes a restricted orifice through which the gas is fed by a compressor, and a pressure sensitive valve downstream from the restricted orifice senses the pressure decrease due to an overloading pin fracture.

Abstract: A safety closure and container assembly including a container, cap and combined spring and sealing member. A retention rib is formed on the inner surface of the skirt of the cap, and a spring and sealing member has a radially projecting flange that engages the retention rib to prevent separation of the spring and sealing member from the cap. Cap and container locking elements are formed respectively on the inner surface of the skirt of the cap and the outer surface of the mouth of the container. The cap and container locking elements are engageable with and disengageable from each other by combined axial and rotary motion of the cap relative to the container. The spring and sealing member biases the cap and container locking elements toward locked engagement with each other when the cap is applied to the container.

Abstract: An electrical control system is disclosed for preventing the speed of an engine from exceeding a predetermined value. The control system includes a reversible motor suitably connected to a throttle control of the engine and further includes motor control circuitry connected to receive an input corresponding to the speed of the engine. When the speed of the engine is below the predetermined value, the control circuitry provides for the operation of the motor in one direction. When the speed of the engine exceeds the predetermined value, the control circuitry provides for the reverse operation of the motor actuating the throttle control to limit the engine speed to the predetermined value.

Abstract: A latch mechanism for a tilting cab vehicle selectively secures a cab thereof to the vehicle frame in a lower use position against movement to an access position.

A coil within the handle portion receives the inner end of a core which has an outer probe end that is received by the probe portion to protect it during demagnetizing of a tape sensing head as an AC voltage provides a pulsating flux to the core. A bulb received within the handle portion of the housing shines light through the probe portion thereof to provide illumination during the demagnetizing. Closing of a normally open switch energizes the coil with the AC voltage and concomitantly applies a portion of the voltage across the coil to the bulb to provide the illumination.

Abstract: A seat back recliner having seat back and cushion arms connected to each other about a pivotal axis for adjustable movement. Plate-like ends of the arms are pivotally connected to each other with a locking ring therebetween fixed to the seat back arm encircling the pivotal axis. Locking teeth of the ring extend inwardly and are arranged in an arcuate shape about the pivotal axis to be engaged by a toothed end of a locking dog that is slidable between the plate ends and between spaced guides on the seat cushion arm end. A spring biased actuator and cam normally position the dog in a locking position where its toothed end engages the ring teeth to prevent pivoting of the seat back arm. A blocking pin on the dog and a blocking surface on the seat back arm cooperate to prevent engagement of the dog and the ring during pivoting of the seat back arm to the easy-enter position.

Abstract: A bearing and a method for making the bearing incorporate annular elastomeric seals that are molded within annular edge grooves of an outer race so as to be bonded thereto while in slidable engagement with an outer spherical surface of a bearing element received within the race. The edge grooves of the race preferably have a relatively rough surface finish in relationship to the outer spherical surface of the bearing element so that there is good bonding of the seals to the race as well as good sealing thereof with the bearing element. Two preferred embodiments each incorporate a lining that is bonded to the outer race prior to a swaging operation which locates the race grooves adjacent the outer surface of the bearing element such that the seals are also bonded to annular edges of the lining during molding within the grooves.

Abstract: A seat recliner of the disclosure includes an adjustment mechanism that adjustably controls the angular orientation of a seat back relative to an associated seat cushion and also includes a latch that releases the seat back for forward tilting movement to an easy-enter position. Seat back and cushion arms are pivotally interconnected along the tilting axis about which the seat back moves and are positioned relative to each other thereabout by the cooperable action of the adjustment mechanism and the latch. A positioning member of the adjustment mechanism is pivotally located relative to the seat cushion arm about the axis by a locking dog that is moved between locking and nonlocking positions by the cooperable action of a cam and a cam actuator. Dog movement to a nonlocking position releases the positioning member to permit adjustment thereof and a consequent change in the angular orientation of the seat back.

Abstract: Apparatus for forming a seal between layers of a carton of thermoplastic coated paperboard material and the like wherein the thermoplastic material in the area to be sealed serves as the sealant and is activated to flow by frictional heat generated by a vibration welding horn and is then allowed to cool and set under pressure to form the seal between the layers. The carton first moves to an activating station wherein the layers to be sealed are engaged on opposite surfaces by a vibrating horn and a back-up means for a time sufficient to activate the thermoplastic material to flow. The carton is then carried to one or more clamping and sealing stations at a different location from the activating station with the thermoplastic material in the activated state. The layers to be sealed with the activated thermoplastic is then engaged on opposite surfaces by a pressure pad and a back-up means for a predetermined period of time to permit the activated thermoplastic to cool and set and form a seal.
