Title: High pressure discharge lamp with a thermally improved anode and method of making
Inventor: MATHEWS PAUL G
IPC: H01J9/02
Filed: 1993-06-03
Granted: 2003-01-07
Abstract: A high pressure discharge lamp with a thermally improved anode, as well as a method of making such a lamp, are disclosed. The lamp includes a refractory arc tube with a hermetically sealed arc chamber, a fill in the arc chamber for facilitating light generation, and an anode and a cathode extending into the hermetically sealed arc chamber and being spaced apart from each other. The anode comprises a shank of refractory metal, a cylindrically shaped refractory metal sleeve on a portion of the shank, and an end proximally facing the cathode. The anode end comprises a substantially solid mass of refractory metal, and is integrally joined to both the shank and the metal sleeve to facilitate heat flow from the anode end to the shank and sleeve. The anode end preferably is generally shaped as a hemisphere facing the cathode. The fill may comprise mercury, metal halide, and xenon at a relatively high fill pressure.      The anode may be formed by, first, providing a refractory metal shank and placing a refractory metal sleeve, e.g., one or more layers of a helically wound refractory metal wire, along a portion of the shank, to form a sleeve-shank combination. A portion of the sleeve-shank combination facing downwards, is then heated sufficiently to cause metal from the sleeve-shank combination to ball up and form an anode end that integrally joins both the shank and the metal sleeve. The heating is preferably sufficient to cause the anode end to ball up into a generally hemispherical shape.

Title: Fluid pressure operated piston engine assembly
Inventor: WALSH JOHN T
IPC: F15B11/15
Filed: 1993-10-05
Granted: 2005-03-29
Abstract: A fluid pressure, operated piston engine assembly, such as a pump assembly, including a fluid pressure operated piston engine and a fluid valve for coupling fluid under pressure to alternative portions of the piston chamber of the piston engine.      The fluid valve includes a valve spool which is translated to effect the alternative modes of coupling pressurized fluid to the piston chamber.      The translation is accomplished by a shifter assembly having a shifter rod attached to the valve spool. The shifter rod includes a pair of diametrically opposed magnets attached thereto. A fork is attached to the piston engine drive shaft at one end and is mounted for limited movement along the shifter rod between the pair of magnets of the shifter rod. The interaction between the flux generated by a magnet carried by the fork with one of the magnets of the shifter rod causes the shifter rod, and in turn the valve spool, to shift from one position to another, thereby re-directing the flow of fluid to the piston chamber to effect the reversal of direction of travel of the piston and its associated drive shaft.

Granted: 1998-02-03
Abstract: Equalizing amplifying circuitry for compensating frequency dependent losses occurring in a signal transmitted over a network such as a cable.  The circuitry includes an equalizing network responsive to the signal transmitted over the cable, the equalizing circuitry having a predetermined frequency response characteristic.  The output signal from the equalizing network is applied to an amplifier and an attenuator applies a portion of the the amplifier output as a positive feedback signal to frequency response characteristic modifying circuitry to vary the amount of current passing through the equalizing circuitry as a function of the amplitude of the positive feedback signal to thereby effectively modify the frequency response characteristic of the equalizing circuitry. Summing circuitry responsive to the signal transmitted over the network and to the output signal from the amplifier provides a corrected signal in which the frequency dependent losses introduced by the network are compensated for with a single control.

Title: Single-based electric lamp base structure with connecting lead strain relief
Inventor: BEHR GERHARD
IPC: F21V23/00
Filed: 1994-08-30
Granted: 2003-02-25
Abstract: To provide a strain relief in a base for an electric lamp, adapted for connection to an external electrical energy source by at least one connection cable (6a, 6b) extending through and into the base, the base (2) is formed with a strain relief arrangement which includes a resilient sleeve (11) having an inner wall surrounding the at least one connection cable and, within the base bottom portion (9, 9'), a sleeve reception structure (9a) positioned inwardly of the bottom of the base, which includes a sleeve reception bore (10a, 10b) receiving and surrounding the resilient sleeve (11a, 11b) and exerting circumferentially uniformly, radially inwardly directed forces on the resilient sleeve. This decreases the diameter of the sleeve so that the inner wall thereof engages, clamps and squeezes the deformable insulation of the at least one connection cable and, also, can interengage or interlock therewith. The bottom portion (9) and the top portion (7) of the base are snapped together. The sleeve (11), preferably, is made of plastic, and made circumferentially resilient by forming one or more axial slits, for example in pairs, extending from opposite ends of the sleeve, so that, upon compression for example due to conical surfaces of the sleeve (11) and/or the bore (10), the sleeve will be essentially circumferentially uniformly reduced in diameter and engage on or into the insulation jacket (12) of the connecting cable (6).

Abstract: A system and method are disclosed for collecting cutting fluid and chips from a number of machine tools includes a series  of  sumps  each  collecting  chips  and  fluid  at  a particular machine tool, and a central sealed collection tank drawing from all of the sumps by drawpipes inserted in each sump.   A single large capacity pump pumps to filtration equipment, with a predetermined vacuum level maintained in the tank by opening and closing an outlet valve between the pump and the filtration equipment.  A level switch at each sump causes intermittent opening of an associated valve causing each sump to be placed in communication with the vacuum in the collection tank,  and random opening of the valves causes individual sumps to be emptied by the full suction at the collection tank.  The drawpipes are equipped with antivortex end shapes to allow rapid evacuation without drawing air into the system.  A vacuum pump removes excess air accumulating in the collection tank.

A down-fill material is disposed between fabric sheets which are secured together by stitched lines. A plurality of tack stitches are disposed between the stitch lines to compress the down-fill material to reduce the thickness of the quilted fabric by at least twice the normal loft of the down-fill material while maintaining pliability of the fabric. The tack stitches eliminates stitch lines which produce cold spots and which add rigidity to the fabric. Such quilted fabric may be used as outer or inner fabric pieces in the manufacture of articles of apparel, for the fabrication of bedding quilts or other articles wherein an insulating fabric is desired.
