Abstract: Jumper cables or battery charging cables for automotive use and the like are disclosed in which at least one of the cable's gripper jaws or clamps is provided with a length of coiled heater-resistance wire. The length of wire is clamped to the portion of the jaw handle opposite that to which the jumper cable wire itself is connected, and extends a short distance outwardly of the handle. The coiled heater-resistance wire is chosen as to have a preferred resistance in the order of 0.5 to 2 ohms and has an exposed free end which may be contacted to the battery terminal prior to connecting the gripper jaws to the terminal to indicate whether the charger cables have been correctly or incorrectly connected. If the connection is incorrect, the resistance wire will sparkle visibly and safely at the point of contact with the terminal, thus indicating the the connection is wrong. If no visible sparkle is seen then the charger cables may be clamped with the knowledge that the connection is correct and safe.

Abstract: In a jet drop recording system a drop catcher includes a drop impinging face having a narrow slot at its lower edge so that drops impinging on the face may travel over it to the slot for removal from the system. A reduced pressure is maintained in the catcher to draw the recording material through the slot and the size of the slot and the pressure differential across it are adjusted so that a meniscus is formed at the mouth of the slot. The surface tension of the recording material then acts in opposition to the reduced pressure tending to draw the material into the catcher and maintains the slot full of recording material. This meniscus, in effect, forms a "seal" which prevents air from being drawn into the catcher and eliminates air currents in the vicinity of the catcher which might affect the trajectory of drops intended for deposit on the receiving member.

Abstract: A mandrel assembly in which the mandrel segments are expanded and contracted by means of a draw rod extending through the mandrel and driven by the same motor that rotates the mandrel during winding or unwinding operations. The draw rod is fixed for rotation with the mandrel but is movable longitudinally thereof and is provided with power threads on one end which are in engagement with complementary power threads on a nut member carried by the motor shaft. A drive gear is keyed to the nut member so that it is rotatable with the nut member but capable of movement longitudinally thereof into and out of engagement with a driven gear secured to the mandrel. A nonrotatable gear segment is mounted for shifting movement with the drive gear and moves into engagement with the driven gear as the drive gear is disengaged from the driven gear to lock the mandrel against rotation.

Abstract: A method of dewatering mineral slimes by adding fly ash and then a polyelectrolyte and blending slowly and thoroughly. The clear water supernatant may be drawn off from the sedimented coagulated solids. The coagulated solids may be further dewatered or treated in ecologically beneficial ways.

Abstract: The knives on the surface of a peeler and grater disc for a vegetable peeling machine are formed from portions of the disc and are integral therewith. The knives are arranged in generally spiral rows from the center of the disc. Upturned reinforcing lips formed from and integral with the disc are located adjacent slots in front of each individual knife. The lips and knives cooperate to define the knife cutting depths. A pair of radially extending ribs on the disc cooperate with spiral ribs along the walls of the peeling chamber to promote circulation and rotation of all the vegetables for uniform exposure of all sides of all the vegetables to the disc.

Abstract: Logs which are to be divided into standard length blocks are first measured and their total length is displayed visually on an electronic readout device. Based on this length measurement, an operator selects one of several standard lengths and causes the log to advance relative to a cutoff saw where it is then cut. Total length measurement is determined by presetting a counter with a count representing maximum possible log length, down counting the counter when the trailing edge is detected and stopping the count when the leading edge reaches a reference position. Movement of the log is obtained from a tachometer generator mounted to rotate with a conveyor drive and an electronic circuit converts the output of the tachometer generator into pulses each representing a predetermined and convenient unit of length measurement.

Abstract: This invention relates to a self-contained thermal limiter construction which can be used to limit one or more electrical circuits and comprises a thermally responsive device having leads for being interconnected into such electrical circuit or circuits and one or more of electrically operated heaters disposed adjacent the device and each being adapted to cause the device to open the circuit or circuits when heated by the respective heater a certain amount.

Abstract: A waste treatment system which is capable of handling materials of widely different physical characteristics such as glass, metal, and fibrous and plastic waste, incorporates a rotor rotatably mounted in a waste receiving vessel, the rotor being adapted to fracture brittle material, compact malleable material, and otherwise pulverize the frangible waste to a particulate form small enough to be extracted through a perforated plate. The rotor also circulates the material in a slurry form within the vessel in a vortical pattern so that the waste is repeatedly treated until it is ejected from the vessel. A series of space attrition bars are mounted outwardly of the rotor to provide an annularly shaped, discontinuous attrition surface, and hammers or flails are pivotally mounted on the rotor to reduce into smaller pieces materials which are flung upon or between the attrition bars by the rotor.
