Title: Mig welder attachment for an electric hand drill
Inventor: HAYES PETER F
IPC: H05B7/11
Filed: 1987-10-15
Granted: 1991-04-09
Abstract: MIG WELDER ATTACHMENT FOR AN ELECTRIC HAND DRILL     ABSTRACT OF THE DISCLOSURE    A dielectric cover (30) is detachably coupled to an electric hand drill (12) of pistol form with a front portion extending beyond the drill  shaft projecting from the front end of the drill casing.  The cover acts as a torque tube to support a right angle drive reduc-tion gear mechanism (38) which terminates in a drive wheel (65) rotating about an axis perpendicular to the drill  shaft  axis  (24)  and within  a friction  drive mechanism, completed by spring biased idler wheel (54) pressing against the drive wheel.  Metal blocks (42a, 42b) mounted to the cover (30) connect to one side of a DC source (122, 122) and mount a wire guide (44) for guiding a thin wire first electrode (90) into contact with and between the drive wheel (65)  and the idler wheel (54).  The wire electrode (90) which is friction-ally pulled from a spool (92) borne by the cover (30) feeds through a conductor tube  (64)  of an electrode nozzle assembly (72).  The conductor tube (68) receives an inert shielding gas which flows about the thin wire first electrode (90) and the arc (124).  The variable speed drill  (12) uses the trigger mechanism (18) to control wire electrode  (90)  feed speed and thus the amperage of the weld arc (124), with workpiece (116) functioning as the second electrode.   Owing to  the inherently stabile arc as derived from storage batter ies (122, 122), arc (122, 122) and drive power (122) sources require no stabilizing interlock and may thus be entirely separate or identical, as convenience may dictate, without affecting either arc or drive either beneficially or adversely.

Granted: 1991-07-23
Abstract: ABSTRACT OF THE DISCLOSURE      A hydrotherapy system is provided including a hydrotherapy tub with a water circulation pump and motor.  Electrical proximity sensor terminals are mounted to the tub on the outside surface, one at a relatively low level for detecting the presence of water in the tub and a second preferably at a higher level for detecting the presence of the user to serve as an "on" and "off" switch which the user can operate by placing his hand in proximity therewith.  Neither of the terminals requires physical contact to be actuated.          Each is connected to circuit means for establishing the presence of an object in proximity with it and each of the terminals is operatively connected to the pump motor so that the pump motor will operate only when both of the terminals are actuated.

Abstract: ABSTRACT     Individual laminas are blanked from sheet strip material and stacked to form a lamina stack for use in electric motor or generator rotors or stators. m e thickness of each lamina is measured prior to stacking, and the individual lamina thickness measurements are supplied to a controller.  The controller monitors the increase in stack height as the individual laminas are stacked and compares the increase in stack height to an operator entered preselected stack height.  Individual laminas are stacked as long as the height of the lamina stack is less than an operator entered preselected stack height.   Individual laminas are continually stacked until the addition of another lamina would cause the lamina stack height to exceed the preselected stack height.   Slotted openings are blanked in each lamina to form a slot in the stacked laminas which is skewed to the stack axis by a constant skew angle by providing that the lamina stack is rotated an angular increment determined by the thickness of the lamina prior to stacking the lamina.

Abstract: ABSTRACT A ratchet screwdriver contains a magnetic clutch assembly which is accessible by external switching means.  The switching means can alternately switch the clutch assembly from a first position to a second position and vice-versa.  When the clutch assembly is in the first position the handle will be in a fixed relationship with the shaft and head when the handle is turned in a clockwise direction but will rotate relative to the shaft and head when the handle is turned in a counterclockwise direction. Alternatively, when the clutch assembly is in the second position, the handle will be in a fixed position relative to the shaft and head when the handle is turned in a counterclockwise direction but will rotate relative to the shaft and head when the handle is turned in a clockwise direction.  Previous ratchet drivers do not operate smoothly or they are much too complex.

Abstract: COOKTOP APPLIANCE WITH IMPROVED POWER CONTROL    ABSTRACT A cooking appliance adapted for energization by a standard domestic household power supply employs a power control arrangement which accommodates electric resistive heating units designed for operation at a maximum RMS voltage level less than the RMS voltage level of the output power signal of the domestic power supply.  The power control system couples power pulses from the external power supply to the heating unit at one of a plurality of available pulse repetition rates, each repetition rate establishing a corresponding RMS voltage level for application of power to the heating unit.  The repetition rate associated with the maximum user selectable power setting for the appliance is effective to apply an RMS voltage level to the heating unit which corresponds to the voltage level for which the heating unit was designed.  When a heating unit is turned from Off to On the power control system overdrives the unit at full supply voltage for a brief transient heat up period to rapidly heat the unit to its radiant temperature.  The duration of this heat up period is controlled as a function of the elapsed time since the unit was last turned Off.

Abstract: Abstract of the Invention The method of this invention provides for the molding of a composite article such as a woven seat for use in fur-niture or automobiles wherein a woven fabric material and a plastic frame structure coact to enhance their respective strength characteristics.  The fabric material is maintained under tension during the molding operation concurrently with the perimetral portion thereof being imbedded in a bonded relation with the frame structure.  The strength character-istics of the woven fabric material are thus increased due to the uniform load distribution over the total area of the fabric seat resulting from the bonded securement of the perimetral portion with the frame structure.

Abstract: CONFOCAL IMAGING SYSTEM             ABSTRACT OF THE DISCLOSURE          A confocal scanning microscope operates to produce a small (preferably diffraction limited) spot on a sample, scan the spot over the sample in a raster pattern, and form an electrical signal corresponding to the intensity of light emanating from the region of the spot.  The electrical signal is communicated to a computer which produces a visual display on a monitor. The optical train between the source (or detector) and the sample comprises first and second scanning elements, each operable to scan the beam in a different direction, an afocal assembly located between the two scanning elements so as to transfer the beam from the first scanning element to the second scanning element, and standard microscope components including an objective.  The light emanating from the sample encounters the objective, the scanning elements, and the afocal assembly prior to reaching the detector.  An aperture is disposed in front of the detector and blocks any light that emanated from points spatially displaced from the beam spot.  The use of an afocal assembly in the optical train thus allows the elimination of pinhole spatial filters from the design.

Abstract: ABSTRACT            Temperature resistant abrasive polycrystalline diamond bodies are described, intended for use as tools in various mechanical operations like turning, milling, drilling, sawing and drawing, having different additions, i.e. amount and composition, of binding, fluxing, catalyst metals at different distances from the working surface. Preferably the metal concentration of the polycrystalline diamond body is decreasing towards the working surface while the metal composition is varied in a way that gives a mechanically stiffer matrix that also has a lower thermal expansion.            In one embodiment the diamond body is high pressure-high temperature-bonded to a supporting body, e.g. of cemented carbide, in order to facilitate the clamping of the tool. In another embodiment the diamond body is brazed to a supporting body or used in a surface-set rock drill bit, i.e. held by a braze metal. Especially good results have been obtained if the hard polycrystalline diamond body comprises three different homogeneous diamond layers on top of each other, each layer having its special amount and composition of relatively low-melting binding metal. These three diamond layers are bonded to each other and to the supporting body, if any, by using intermediate layers of the thickness 3-300 µm, consisting of more high-melting metals or other materials like nitrides or borides, etc. in order to lock in the low-melting binding metals and to prevent diffusion of these metals between the different diamond layers and between the supporting body and the nearest diamond layer.
