Abstract: A method of forming an elongated tubular blank into a tubular structural component having a predetermined outer configuration, the method comprising: providing a shape imparting shell formed from a low permeability, rigid material which includes an inner surface defining the predetermined shape, plugging the open ends of the tubular blank, placing the plugged blank into the shell, and forming the tubular blank into the tubular component by inductively heating axial portions of the blank by axially spaced conductors adjacent the shell while or before forcing gas at a high pressure into the plugged blank until the blank conforms to at least a portion of the inner surface of the shell to form the structural component.

Abstract: A brushless repulsion motor which includes a stator and rotor rotatably mounted on the stator is provided. The stator and rotor are contained within a first housing, the stator having at least one pair of poles, a field winding on the stator for producing a field on the stator, and a plurality of coils on the rotor adapted to electromagnetically interact with the field of the stator winding. Switches are located on the rotor shaft outside the first housing to selectively short successive ones of the coils when the coils are in a preferred angular position relative to the stator poles. Thus, the stator field is effective to induce a current in the rotor and produce a resultant relative rotation between the rotor and the stator which can be controlled by non-contact signaling means which activate the switches.

Abstract: A motor for controlling the elevating and lowering of a load comprises a storage drum, an output drum and a spring member operatively connected therebetween to provide a spring motor therewith, and a pair of cord drums aligned with and respectively adjacent the storage drum and the output drum. A gear train including an idler gear associated with the storage drum drivingly interengages the cord drums with the output drum, whereby the elevating and lowering of a load attached to the cords on the cord drums is balanced regardless of whether the elevating or lowering force is applied centrally between the points of attachment of the cords to the load.

Abstract: A motor mount assembly for use with a hydraulic system of a snowplow. A motor mount has a mounting surface for receiving a motor and a recessed surface from which interengaging components protrude. A motor has a suitable mounting surface for mating with the motor mount and a pilot surface from which interengaging components are recessed. The proper alignment of the interengaging recesses of the motor with the complementary interengaging protrusions of the motor mount allow the mounting surfaces to abut such that the motor can be securely attached to the motor mount.

Abstract: The invention relates to a multi-spindle machine tool, in particular a multi-spindle automatic lathe with several workpiece spindle units. These are arranged around a central axis, can be driven rotationally and can be advanced from one machining position to the next. In order to provide the greatest possible flexibility in the machining of workpieces in a machine of this type, the invention envisages that the workpiece spindle units can be moved independently of one another along a movement path running around the central axis. The machining positions are designed in the form of machining segments within whose limits the respective workpiece spindles or workpiece spindle units can move along the movement path during a machining process.

Abstract: An improved low profile mounting arrangement is provided for a telescoping tube construction applied to the roof of a vehicle. The lowest mast section is nested between two vertically upright shaft support plates which journal a pivot shaft rotatably secured to a collar affixed to the bottom of the lowest mast section whereby rotation of the pivot shaft causes the telescoping mast to rotate from a horizontal to a vertically upright position. A pivot link mounted to an end of the pivot shaft extends downward adjacent a support plate side opposite to the side facing the telescoping mast so that an actuator secured to the pivot link is mounted on the side of the telescoping mast construction to achieve a low profile mount with minimal vertical elevation.

Abstract: A fueling assembly for a fuel tank of an engine driven welder. The engine driven welder has a housing having a top portion, a side portion and a fueling cavity. The fueling cavity is formed in the top portion and the side portion of the engine welder housing. An engine and a fuel tank are located within the housing. The fueling assembly includes a filler tube, a fuel gauge and a grommet to seal the filler tube and fuel gauge in the fueling cavity. The fuel gauge has a fuel level indicator and a fuel level sensor that extends through the filler tube and into the fuel tank. The fuel level indicator registers a plurality of fuel levels in the fuel tank. The grommet is a one piece structure having a lower intermediate section which includes an opening to provide access to the filler tube opening and the fuel level indicator. The side section of the grommet has flanges to connect the grommet to the engine welder housing.

Abstract: An electric arc welder comprising a plurality of power supplies connected to a single welding station with a D.C. input for passing an arc welding current across an electrode and workpiece, each of the power supplies including a switching type inverter with an output D.C. current determined by a signal applied to the input of the power supply, a circuit connecting the output D.C. currents in parallel at the input of the welding station, a feedback circuit including a sensor for creating a current signal representing the arc current, a command signal source, and a circuit for creating a master current signal based upon the sensed current signal and the command signal, and a circuit for applying said master current signal to the input of the plurality of power supplies whereby the D.C. current to the D.C. input of the welding station is equally shared by the power supplies.

Abstract: An improved pneumatically telescoping mast supported for pivotal movement in opposite directions is provided. The mast includes adjacent telescoping sections slidable relative to one another between retracted and extended positions. A pneumatic control system for displacing the mast sections between the retracted and extended positions is also provided, as is a mechanical arrangement for pivoting the mast between generally horizontal and vertical positions. The mechanical arrangement includes a drive mechanism operable independently from the pneumatic control system which is capable of securely maintaining the mast at any desired angle between the horizontal and vertical positions. The mast includes an AC powered light source mounted at the upper end of the mast.

Abstract: The method of the invention provides that a predetermined quantity of molten glass necessary for producing molded glass bodies according to the press-molding method is poured into a press mold prior to the insertion of the molding plug while the press mold is located in the press station, and that the molded glass body is removed after the molding plug is withdrawn from the press mold, with this mold likewise being located in the pressing station. This method renders a mold transport superfluous. The invention also relates to an apparatus suitable for executing the method, in which the molding plug can be pivoted laterally from its initial position located outside of the press mold about an axis extending transversely to the center axis of the molding plug.
