Abstract: A fan guard comprising front and rear portions each including a plurality of radially extending wires circumferentially spaced supporting a plurality of concentrically mounted wire rings. Some of the radially extending wires include an end having a homogeneously extending tab formed thereon. The tabs have a front and back side and are formed by bending the end of the wires into a P-shaped loop defining a slot having parallel edges. The tabs are offset with respect to the portion's joining plane so when the guard portions are assembled the front side of the tabs of the front portion engage the back side of the tabs of the rear portion to form abutments with each other in an interlocked relation preventing axial separation of the guard portions and the loops align to receive a bolt upon which a nut is threaded to secure the guard portions together.

Abstract: Broach pulling apparatus which eliminates play and backlash during the broach operation. Jaws carried by the broach pulling spindle engage the broach in a manner to impose axial forces thereon in opposite directions to eliminate lost motion and clearances between the spindle and the broaching tool during cutting and alignment.

Abstract: A bonding system for assembling internal combustion engine crankshaft vibration dampers having an annular inertia ring mounted upon a hub by an elastomeric ring interposed between the inertia ring and hub. After assembly of the components, a thermosetting adhesive located between the elastomeric ring and the inertia ring and hub is heated to a bonding temperature by low frequency electrical induction. The damper components are mechanically clamped during heating and the elastomer is permitted to thermally expand. Heat is concentrated adjacent the adhesive to minimize thermal aging and degrading of the elastomer.

Abstract: A camshaft damper system for damping torsional vibrations within a camshaft for an internal combustion engine. The drive sprocket attached to the end of a camshaft includes radial projections and recesses meshing with the flexible camshaft drive belt or chain and the sprocket includes torsional vibration damping means in the form of an annular inertia ring and elastomeric member attaching the inertia ring to the sprocket wherein torsional vibrations are absorbed by the elastomeric material reducing wear on the camshaft and the camshaft-related components.

Abstract: A system for monitoring animal body functions by analyzing the condition of the gas being breathed. A breathing tube, usually constituting a portion of anesthesia apparatus, contains sensing means in the form of a thermobead whose electric characteristics vary in accordance with temperature variations as heat is exchanged between the thermobead and the respiratory gas. Electronic analysis of the thermobead characteristics permits animal body functions such as breathing rate, breathing volume, animal body temperature and the like to be determined. Digital displays, recorders and alarms may be activated by the thermobead output.

Abstract: A system for fabricating fan blades wherein the assembly includes a flat hub plate having generally radially oriented notches defined therein intersecting the plate periphery. Individual blades each include a hub connection portion adjacent an inner end region which includes parallel flat portions angularly related to the general blade configuration interconnected by a transition portion. The flat blade portions are located upon opposite sides of the hub plate and the transition portion extends through the hub plate notch. The flat portions are attached to the hub plate, and by predetermining the position of the hub connection configuration on the blade, the fan characteristics can be predetermined and accurately duplicated. The system permits a standard set of tools to form a variety of sizes of fan blade components having various characteristics.

Abstract: A receptacle for delivering food in a hot condition in the form of a bag formed of insulating material having a closure defined at an end. Within the bag an insert of a high density material capable of retaining heat is located and is heated by an electric resistance heater. Prior to use, the insert mass is heated to the desired temperature and food, such as pizza, placed within the bag will stay warm due to the heat retention of the mass. A plurality of bags are stored in a heated condition so as to be ready for use as needed.

Abstract: A guide for garden hose to guide the hose during movement over the lawn. The guide has a nonuse condition fully retractable below the lawn level, and in use includes a roller elevated above the lawn level for engaging a hose moving thereover. Detent structure maintains the guide roller in the elevated position.

Abstract: A fire truck characterized by its reduced operating noise level and improved drive train includes a frame having front and rear regions. An occupant cab is mounted upon the frame front region, and the engine is located at the rear region having a transmission associated therewith. A gear box mounted upon the frame intermediate the front and rear regions includes a close coupled fire pump attached thereto and the gear box includes an input shaft directly connected to the engine transmission. An output shaft of the gear box is directly connected to the differential associated with the vehicle rear wheels, and shifting means within the gear box selectively connects the engine and transmission to the differential or the fire pump. The fire pump gear box eliminates an intermediary transfer case and provides significant cost and weight advantages as well as eliminating the need for special power transmitting components.

Abstract: Method and apparatus for dewatering mill tailings, slimes and slurries, wherein ultra fine particles materially reduce the rate of natural dewatering and hinder their disposal in the mining and processing of phosphate, coal, potash, uranium, talc and the like. The invention is preferably carried out in a closed loop system involving the use of electrokinetic densification and substantially continuous decanting of the supernatant.

Abstract: A drain plug for draining oil from vehicle oil pans including a body having a threaded stem for permanently attaching the body to the pan threaded drain hole, a valve threaded into the body includes a conical seal surface seating against a conical valve seat within the body bore. The valve includes an axial bore having inlet ports receiving the pan oil upon the valve seat disengaging from the body seat wherein draining of the oil can be accomplished by rotating the valve relative to the body without removal of the valve from the body. Torque transmitting wrench flats defined on the body and valve are sufficiently spaced apart to prevent simultaneous accidental loosening of the body in the pan drain hole.

Abstract: An end cap for small electric motors using brushes, the end cap being molded of a synthetic plastic dielectric material. Brush-receiving guides are defined on the end cap by homogeneous cantilevered fingers which are deflectable to grip the brush therein during assembly of the end cap to a motor casing. Electric conductor and connector retainers are homogeneously defined on the end cap to provide conductor strain relief, a circuit breaker retainer is homogeneously included in the cap configuration, and tie bolt ears are of such configuration as to cooperate with the motor casing to resist deflection.

Abstract: A fueling nozzle for pressurized fuel systems having a body connectable to a tank inlet. The body includes an axially displaceable valve movable between a closed retracted position and an extended open position. Connection of the body to the tank inlet occurs upon rotation of the connection sleeve and positioning of the valve is achieved by a rotatable cam sleeve having a cam slot in which a valve-mounted follower is located. An interlock senses mounting of the body on the tank inlet permitting rotation of the connection sleeve in a locking direction and upon the connection sleeve being fully rotated to a locked condition a second interlock permits rotation of the cam sleeve and valve movement from the closed to the open position. The nozzle is characterized by reduced flow resistance characteristics and safe operation.
