Abstract: Inventor:  Alvin L. Heinze Title   :  TAG WHEEL LIFT                     ABSTRACT OF THE DISCLOSURE         A tag wheel lift includes first and second brackets, spaced longitudinally and provided with inner and outer legs, with the former being attached to a mounting plate by spacing blocks which provide clearance for nuts for pivot bolts which extend through the legs.  One end of a leaf spring for the corresponding tag wheel is pivoted on a bolt or pin extending between the lower ends of the legs of the first bracket, while the other end of the spring is pivoted between a pair of lower links, at the lower rear corner of a rearward offset.  A hydraulic cylinder is pivoted on the first bracket, while the piston rod thereof is pivoted between the movable ends of a pair of upper links, on the same pivot which connects the upper links with the lower links.  The upper ends of the upper links are pivoted between the inner and outer legs of the second bracket, with the outer leg being re-stricted in length to provide clearance for upward movement of the lower links to folded or retracted position, with the rearwardly extending offset moving past the outer leg of the second bracket. This moves the corresponding end of the tag wheel spring to a higher position, to place the corresponding wheel a sufficient distance above the road.  In extended position, the links are essentially in line, to cause the tag wheel to engage the rod beneath.  A tag wheel lift is mounted on each side of the chassis and the two are retracted and extended simultaneously, through appropriate controls.

Abstract: Abstract The semiconductor device includes a layer of silicon nitride (Si3N4) beneath a phosphosilicate glass (PSG) layer.  The silicon nitride impervious layer prevents the oxidation of underlying, exposed silicon regions during a "flow" step and any "reflow" step.  Accordingly, the flow of the PSG layer can be conducted in an atmosphere containing steam, which means that the PSG layer can contain less than about 7% phosphorus by weight.  The reduction of the phosphorus content of the PSG layer provides increased reliability for the semiconductor device. The method of manufacturing such a device is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE In a labelling machine a layer of glue is applied to a rotating glueing roller and a series of glueing pallets moved in succession past the glueing roller have the receiving surface thereof rolled against the glueing roller to transfer a coating of glue to the receiving surface for subsequent application to a label.  The gap during this rolling operation between the receiving surface and the glueing roller must be closely controlled.  However through malfunction of the machine unwanted label material may be present on the receiving surface when it is rolled against the glueing roller.  Therefore it has been customary to make glueing rollers of hard rubber composition, but such rollers are subject to damage or even destruction should extraneous label material become wedged between the scraper and the glue roller.  These difficulties are obviated by providing a glueing roller having a cylindrical mantle surface of rigid wear resistant material which is resiliently support-ed on a sleeve of the roller and accordingly is radially yieldable to accommodate their presence of extraneous labelling material.

Abstract: ABSTRACT OF THE DISCLOSURE     A shear is disclosed in a preferred form which is particularly suited for cutting and trimming hair and which in-cludes means for varying the length of stroke of the cutting blade or blades which reciprocate generally parallel to the longitudinal axis of the handle, so that the unit can be manipulated in a manner similar to a comb or brush.  The blade drive includes a transmission comprising a pair of eccentrics which are selectively phaseable to provide full range of stroke by addition and subtraction of their eccentric throws.  The eccentrics are retained in their selected phase relationship by spring and frictional means which provide an overload release permitting the eccentrics to rephase to zero stroke when the imposed load overcomes the phase-retaining means.  Control of the unit is effected by a rotatable and depressable button which controls the drive motor, adjusts the blade stroke by phasing of the eccentrics, and levers the cutting blade or blades from a retracted position into a cutting position.

Abstract: ANTI-SURGE VALVE              FOR HYDRAULIC LOCKING DEVICE               Abstract of the Disclosure An anti-surge valve for installation in a cylindrical chamber permits a fluid to flow at low velo-city into and out of a port that opens into the cylin-drical chamber and is located on the concave wall of the cylindrical chamber, the valve-preventing a high velocity flow of the fluid from the cylindrical chamber into the port.  The valve includes a sealing tube that is positioned within the cylindrical chamber in juxtaposition with the port and coaxial with but spaced radially inward from the portions of the concave wall that surround the port.  The sealing tube is maintained in this position by spacers surrounding the sealing tube and extending radially out-wardly to the inner surface of the cylindrical chamber.          The anti-surge valve is a unitary structure molded of rub-ber.  The sealing tube is sufficiently stiff that at low flow velocities the sealing tube is not drawn toward the concave wall sufficiently to interfere with low velocity flow, but the sealing tube is sufficiently-flexible that at high flow velocities, the sealing tube is drawn against the portion of the concave wall that surrounds the port, thereby sealing the port and preventing high velocity flow of the fluid from the cylindrical chamber into the port.

Abstract: BULK MATERIAL HANDLER AND FEEDER                        ABSTRACT       A bulk material feeder has two rollers, at least the lower of which is driven.  Strip material is threaded around the side of the upper roller toward the direction of feed, between the rollers, around the said of the lower roller opposite the direction of feed and to downstream machinery spaced from the feeder.  Roller spacing is greater than material thickness precluding compression of the material.  Feed is produced by fric-tion between the roller and material only.  Feed rate is greater than usage thereby producing a depending loop between the feeder and the downstream machinery. In one embodiment, increasing loop size decreases material and roller contact, causing relative slippage and a discontinuance of feed.  In another embodiment, both rollers are driven and loop size is limited by a photoelectric device and associated control circuitry.
