Abstract: Alkaline lubricants for use with glass, aluminum and PET containers and other articles of manufacture are prepared from water-soluble amines. Fatty acid lubricants prepared herefrom are rendered highly dilutable by employing myristic acid as at least a portion of the fatty acid component thereof. Synthetic diamine lubricants are prepared by using the water soluble amines as the hydrotrope for the synthetic diamine, without the neutralization thereof.

Abstract: A method of embrittling cleaned steel particles is described, followed by a grinding and sorting operation. Depending on the initial carbon content of the steel scrap, a reducing and carbon-containing atmosphere may be provided to carburize the particles as they are being embrittled. A quenching operation is provided at the end of the process to embrittle the particles and before the particles are ground. The ground grit which is produced may then be sorted by size and used as an abrasive compound, or, alternatively may be further ground and annealed in a subsequent operation to provide suitable powder for forming sintered parts. Prior to annealing the grit may be further ground in a partial oxidizing atmosphere to preoxidize the powder, in order to provide oxygen directly within the powder to react with any residual carbon so that the carbon monoxide gas can be formed and the powder can be substantially free of both carbon and oxides when the reaction is complete.

Abstract: An apparatus for removing a cover from a transport car is mounted to the car and has a swing member connected to the cover of the car. The swing member is pulled away, with the cover, by rolling down a pair of guide members to a termination point. A winch is used to pull the swing member back into position to block the opening of the transport car with the cover. The apparatus allows manual removal or placement of the cover on the transport car in environments where the space over the car is restricted.

Abstract: A protective covering device suitable for protecting the surface of the wheel rim of an automobile against damage by toxic cleaning solutions used to clean the surrounding tire. The shield is temporarily attached to the rim with a grasping device which provides assistance to the user who is holding the protective device over the rim while applying cleaning solution to the surrounding tire.

Abstract: A mirror mounting bracket for mounting mirror assemblies to truck or van type vehicles which have slanted front ends that extend at an angle from the windshield toward the ground. The mounting bracket includes a mounting member which is attached to the vehicle and a clamping member with a living hinge which receives and holds the mirror assembly. The mounting member accommodates the slanted front end of the vehicle while the clamping member positions the mirror assembly vertical to the ground.

Abstract: A buck spindle for supporting a fascia during a painting process comprises an interconnected structure of steel tubular members. Forming the structure of tubular members allows dissipation of heat, which adversely affects the paint quality of fascia and other automobile parts during the paint baking process, as well as offering a lighter weight buck. Utilizing steel prevents the deposit of a chalky residue, which occurs with aluminum cast bucks.

Abstract: A thermostatic mixing valve and method of use thereof. The thermostatic mixing valve is controlled by the incoming hot and cold fluids, which are mixed in a mixing chamber, by a thermally responsive element disposed in the flow of the fluid mixture in a fluid outlet from the mixing chamber. A distributor for distributing the flow is controlled by the thermally responsive element. A drive is activated by pressure of the fluid and is connected to the distributor for controlling the position of the drive. The distributor is used to control the hot and cold fluid flows. Channels are provided to connect the distributor with one of the fluid inlets, to connect the distributor with the outside of the valve body to conduct away used operating fluid and to connect the distributor with the drive.

Abstract: A work-study cubicle which can accommodate multiple students affords easy teacher supervision and interaction. The cubicle area is separated by at least one slide panel into individual work areas. The panels may be removed to afford larger work spaces. The front area of the cubicle is open to allow eye contact of the study with a teacher. Face-to-face conferences may also be afforded by this cubicle.

Abstract: A nut runner for applying torque to a workpiece such as nut, bolt or the like positioned at a right-angle to the fastening device. The nut runner includes a motor, a speed reduction gear assembly, a right-angle bevel gear system, a planetary gear system, an in-line torque transducer disposed between the bevel gear system and the planetary gear system, a torque reading transmitter, and a workpiece engaging member. The bevel gear system, planetary gear system and torque transducer form a concentrated assembly which provides for a compact nut runner to access confined assembly areas. The motor causes the engaging member to rotate. The torque transducer senses the torque and the torque reading transmitter sends the reading to an operator or controller which interrupts the power supply to the nut runner when a predetermined torque is reached.

Abstract: Non-chlorinated, low alkalinity, high retention liquid hard surface cleaner concentrate and use solutions containing an amine oxide surfactant, an anionic surfactant, a hydrophobically modified polymer surfactant, a thinner, and alkali are provided, which form viscous solutions upon dilution and which in cleaning operations, are capable of producing gel-like foams. The composition synergistically exhibits exceptional cleaning performance without the need of chlorine or high levels of caustic.

Abstract: Apparatus for perforating corrugated tubing of large diameter is achieved by use of multiple cutters disposed within the threading on the feeder-cutter wheels. The apparatus receives tubing to be perforated along an axial path coincident with the axis of the tubing. A plurality of feeder-cutter wheels drive the tubing through the apparatus and concurrently perforate the tubing in the valley of its corrugations by virtue of a plurality of cutters disposed within the threading. These multiple cutters allow perforation of larger diameter tubing in the range of nine to twelve inches. Each feeder-cutter wheel, and the drive shaft each wheel is mounted upon, is offset at an angle relative to the axial path, this angulation facilitating uniform perforations at higher speeds. This design permits the wheels to be interchangeable with different wheels, allowing the apparatus to perforate tubing of different diameters.

Abstract: A structurally networked matrix ceramic composite material is disclosed as comprising either a continuous ceramic skeletal structure or a series of noncontinuous ceramic skeletal structure surrounded by a resilient polymeric, metallic etc. material to obtain a structural composite with a high compression and tensile strength of ceramics while permitting an accurate prediction of the strength of the resulting composite. Alternatively, the skeletal matrix structure could have no surrounding material or substrate. The matrix structure distributes to all connecting members the compressive and tensile forces resulting from loads on the overall composite.

Abstract: A device for verifying or measuring a minimum value of a previously applied torque on a workpiece such as bolt, nut, etc., includes a motor, a reduction gear assembly, a torque transducer and a fastener engaging member, including a rotatably spindle. The motor causes the spindle to rotate. A torsion bar interposed the spindle and the motor absorbs the inertia of the motor when the motor is stopped to minimize torque overshoot, as well as taking up the rotation generated by the motor immediately upon engagement with a workpiece. An angle encoder senses any rotation of the workpiece caused by the rotation of the spindle. Any rotation of the workpiece means that the previously applied torque is below a minimum predetermined value.

Abstract: A tubing perforating machine can perforate tubing at a high rate of speed. The perforator may also cut tubing of a higher rigidity, particularly dual wall tubing. This is achieved by facilitating the movement of the cutting wheels to compensate for production fluctuations of the tubing.
