Abstract: An automatic welder is used in an internal welder unit which travels along the interior of a pipeline and welds the abutting ends of the pipe segments together. The automatic welder has a carriage assembly that contains a laser source for producing a laser beam, first and second line-up clamp assemblies for aligning the respective abutting ends of the pipe segments together, at least one laser beam conductor, or alternatively a reflecting surface positioned between said first and second line-up clamp assemblies along the axis of said beam, for directing said beam to the abutting ends of said first and second pipe segments, and a drive for rotating the reflecting surface around the axis of said beam to direct the beam to the abutting ends of said pipe segments for welding said pipe segments together. The automatic welder can also be configured as an external welder in which the automatic welder carrying a laser source is carried on a track mounted on the outside of the pipeline.

Abstract: A composition for administration to the nasal mucosa of a subject comprises a solution of nicotine or a pharmaceutically acceptable salt thereof in a pharmaceutically acceptable solvent. The composition has a nicotine concentration in the range of about 10 to about 40 mg/ml and contains a suitable agent to produce a viscosity in the range of about 1 to about 30 centipoise. The composition assists in reduction of the desire of the subject to smoke tobacco or provides a substitute for tobacco smoking.

Abstract: A process for making steel wear plates for use as railroad car truck side frame/bolster damping components utilizes the sequential steps of heating, pressing, quenching and then tempering. The heating process includes bringing the wear plate to a temperature of approximately 1750.degree. F. so that the plate is essentially 100 percent austenite. Generally uniform pressure is applied to the plate while heated to bring the plate to a desired flatness. Quenching fluid is thereafter applied to the flattened plate, while maintaining pressure thereon, to bring the plate to a predetermined brinnell hardness, a predetermined temperature, and a metallurgical characteristic of at least 90 percent martensite. The plate is thereafter tempered at a temperature of from 910.degree.-940.degree. F. for a period of time sufficient to bring the plate to a brinnell hardness less than the hardness after quenching.

Abstract: A power tool has an application mechanism (300) for connection to the output of an epicyclic gearbox provided with a torque control ring. The mechanism has a body (310) journalling a chuck spindle (302). Outside the body is a clutch control arrangement comprising balls (334,336) pressed against the torque control ring by individual springs (330) controlled by a control ring (322) threaded on the body. The mechanism includes a hammer arrangement having rotary and fixed ratchet plates (378,376) and cam ring (308) operable to engage and separate the plates by a lever (360) which projects between the springs (330).

Abstract: A chuck spindle device (300) has the following basic components:--a body (310), a bearing (316) mounting a chuck spindle (302) and an end cap (312) through which the spindle projects for connection to a gearbox. An annular space is defined in the body to receive a hammer mechanism in the form of rotary ratchet (378), fixed ratchet (376) and cam ring (308) to press them together. The body has a slot to accept a control knob (360) of the cam ring. The body is threaded (317) to receive a clutch mechanism in the form of control ring (322) and multiple springs (330) pressing balls (334,336) against a torque control ring of the gear box.

Abstract: The present invention is directed to a computerized control system for use with a cooking system, such as a deep fat fryer. The control system has a plurality of separately accessible control levels. The control system has a control pad comprising a plurality of function switches. Each of the control levels may be accessed by simultaneously depressing a particular combination of function switches. Cooking parameters can be entered at each level, so that unique cooking parameters for various types of food products can be individually programmed into the control system or so that a single set of cooking parameters for use with all food products can be programmed into the control system. During a cooking cycle, the status of the cycle for a particular product and the usage of that product may be displayed on a control pad.

Abstract: An ornamental assembly for use in a non-aquatic viewing cage of the like is disclosed. The ornamental assembly includes a body member formed from a natural indiscriminate piece of driftwood and a fastening assembly for semi-permanently fixably securing the body member to any surface of the viewing cage.

Abstract: An ornamental assembly for use in fluid filled viewing tanks such as aquariums or the like which enhances the aesthetic nature of the tank. The ornamental assembly has a decorative body and a suction cup means for semi-permanently securing the decorative ornament to an inner surface of the viewing tank.

Abstract: A lineup clamp (10) is disclosed which is particularly suitable for clamping to smaller diameter pipe sections with their ends abutting for welding. Pipes less than twelve inches in diameter can be clamped by the clamp (10). The clamp includes a first resilient element (24) and a second resilient element (28) separated by a separator (26). A hydraulic cylinder (20) is activated to resiliently deform the elements (24, 28) against the separator and the inner surfaces of the abutting pipe sections to clamp the pipe sections in alignment for welding. The clamp is released by removing pressurized hydraulic fluid from the hydraulic cylinder and permitting the resilient elements to rebound to their relaxed configuration.
