Title: Rapid exit herringbone stall
Inventor: NELSON WILLIAM S
IPC: A01K1/06
Filed: 1992-12-16
Granted: 2003-09-16
Abstract: A herringbone-type milking parlor of the type in which the cow is milked from the side utilizes a rotating rail that moves from a horizontal exit position to a vertical position to urge the cow to exit from the milking stall. The rail stays in this position until a new cow has moved into the milking stall, at which time the rail indexes back to a position short of vertical to engage the brisket of the cow and move it gently back towards the rump rail and into a proper milking position.

Abstract: Process and device for welding sheets by laser to form compound sheets.  In the process, the sheets which are to be butt welded are positioned with their edges in contact with one another.  To reduce the gap to a width acceptable for  laser  welding,  at  least  one  sheet  is  plastically deformed along the line of the joint so that material flows towards the gap, reducing the width of the gap.   In this way, sheets cut to size with much less precision can be welded together.

IPC: C07C309/11
Filed: 1992-03-03
Granted: 1998-09-15
Abstract: A process is provided for sulfonating an organic reactant which, upon sulfonatio n, produces a viscous sulfonation reaction product having a viscosity substantially greater than 1,500 centipoises at a rea ction temperature wherein the sulfonation reaction product is more than 85 % by weight completely reacted. The process utilizes an elongated, enclosed reactor surface greater than about 15 feet in length having upstream and downstream ends and equipped with a heat exchanging surface. The process comprises cocurrently flowing a film of organic reactant and a gaseous sulfonating agent d ownwardly in the reactor while pressurizing the sulfonating agent cocurrently along said reactor surface while providing a p ressure drop between upstream and downstream ends of the reactor to impart sufficient velocity to the gaseous sulfonating age nt to thin the film of the viscous sulfonation product. The reactor surface is provided with sufficient length to subject the f ilm to contact with the high velocity gaseous mixture for sufficient time to produce a sulfonation reaction product which is greater t han about 85 % by weight completely reacted.

Abstract: A method and apparatus for manufacturing a plug-type chamber to accommodate at least two floating plugs for use in the cascade drawing of tubes are disclosed.   A starting tube is first fixed in position by a clamping and denting device.  A necking-down ring is subsequently moved with the help of a necking-down cylinder along a freely projecting end section of the starting tube.  A punch is then pushed with the help of a cylinder into the end section of the tube.  When the punch has reached its end position, the necking-down ring is pulled over the end section of the tube, and the outside diameter is reduced to its original size.     The  punch  is  subsequently  removed,  and  two indentations are made on the periphery of the end section of the starting tube with the help of the clamping and denting device.  Together with a drawing point produced through the reshaping of the unattached end of the starting tube, these indentations then form a plug-type chamber, in which several floating plugs are embedded, which interact with drawing dies during the cascade drawing operation.

Abstract: A cabinet door or doors are each hingedly mounted to the slide brackets of a pair of slide track assemblies which, in turn, are secured to a side wall of a cabinet.      A pair of inelastic cables of substantially the same length connect the upper and lower slide brackets in a prescribed configuration to prevent skewing of the slide brackets at all times. One of the cables extends rearwardly from the upper bracket across an upper rear pulley, downwardly and forwardly around a lower front pulley and back into the lower bracket. The other cable follows the opposite path from the upper bracket forwardly around an upper front pulley, downwardly and rearwardly around a lower rear pulley, and forwardly into the lower bracket. Because the cables are of equal length, they insure that vertical alignment is maintained.

Abstract: An improvement in a method for the manufacture of electronic surveillance tags by providing a continuous web of electrically insulative material, applying to opposed surfaces of the electrically insulative material web a succession of first and second electrically conductive coils and applying to the succession of first electrically conductive coils a normally electrically insulative deactivation structure extending across the first coil succession and convertible to be electrically conductive, the improvement comprising the step of providing an electrostatic charge drain in electrically conductive relation with each of the first electrically conductive coils substantially throughout the manufacture of the tags. The new step may be practiced by providing an elongate electrically conductive member across the succession of first electrically conductive coils in electrical continuity therewith.     Alternatively, the step may be practiced by configuring the succession of first coils integrally with the electrostatic charge drain. In either case, the drain is removed in a final stage of tag manufacture. Other improvements are also set forth.

Abstract: An electrical rail conductor assemblage for an in-sulated electrification system, including an elongate electrically-conducting rail having a longitudinal groove for receiving a cooperable collector shoe and for guiding it for travel along the rail. The rail has oppo-site wall portions which border the groove. The wall portions have thin wall sections with rounded longitudinal edges that constitute the mouth of the groove of the rail. The rail is covered by an essentially tubular, insulating, hollow, resilient and rigid cover member enveloping essentially all portions of the rail except for the mouth of the groove thereof. The cover member has a longitudinal cut which registers with the mouth of this groove, and curved, longitudinally-extending snap-on retainer portions that extend along the cut and are adapted to snap over the rounded longitudinal edges of the rail. These retainer portions extend in a circumfer-ential direction through substantially a full semi-circle.      The advantage of the present constructions is that these retainer portions have exterior longitudinal flanges which constitute offset extensions of the opposite wall portions of the resilient cover member, to thus minimize access to the metal of the rail, and reduce the chance of inadvertent electric shock from an electrically live rail.

Abstract: A liquid jet is employed to roughen the surface of a substrate so as to enable a subsequent thermal  spray coating material to adhere tightly to the surface.   The substrate is preferably a superalloy that is either nickel, titanium or cobalt based.  The method initially provides a high pressure liquid jet and moves the liquid jet across the substrate surface at a rate so as to deliver liquid to the surface in a range of amounts of at least approximately 0.7 kg/cm2 to approximately 5.5 kg/cm2.  The high pressure liquid jet is preferably provided from a reservoir that is maintained at a pressure in the range of approximately 28 ksi to 52 ksi.  A preferred embodiment employs an initial blast of a grit to the surface of the substrate to remove a  smooth  finish  from  the  substrate,  prior  to  the application of the liquid jet.   The initial grit blast enables substantially lessened pressures and amounts of applied liquid mass to accomplish desired ranges of surface roughening.
