Abstract: APPARATUS AND METHOD FOR INDIVIDUALLY PRINTING SIGNATURES DURING DELIVERY TO A BINDERY LINE                    Abstract of the Disclosure An apparatus and method for individually printing signatures during delivery to a bindery line where a plurality of signatures are provided at a feeding station for delivery to a binding line conveyor.  The signatures are transferred by a transfer conveyor which extends  from a point near the feeding station to a point near a binding line conveyor.  A main drum assembly preferably moves the signatures one at a time from the feeding station to the transfer conveyor which follows  a  path  to  a  delivery  drum  assembly  where  the signatures are delivered one at a time from the transfer conveyor to the binding line conveyor.  The transfer conveyor is adapted to receive one signature at a time from the main drum assembly after which the transfer conveyor carries the signatures  to the  delivery drum  assembly which delivers signatures one at a time for deposit on the binding line conveyor.    In  addition,  the  signatures  are  individually printed by a non-contact printer in a direction perpendicular to the backbones  thereof during the  course of signature transfer by the transfer conveyor.

Title: Coated glass and method of manufacturing same
Inventor: TERNEU ROBERT
IPC: C03C17/34
Filed: 1991-08-19
Abstract: Pyrolytic tin oxide coatings formed on soda-lime glass, particularly those formed from a tin chloride precursor, suffer from haze at the glass/coating interface due to the migration of sodium ions from the glass into the coating. Tin oxide coatings also exhibit iridescence in certain thicknesses.      In order to reduce iridescence and to provide a barrier against the incorporation of sodium into the tin oxide layer, the glass is first provided with an undercoating layer of oxidised metal which contains aluminium with a minor proportion of vanadium. The optical thickness of the undercoat is selected for the reduction of reflected visible light interference effects due to the tin oxide overcoat. An intermediate product comprises a glass substrate bearing a pyrolytically formed oxidised metal coating which comprises a layer in which said metal comprises aluminium with a minor proportion of vanadium and which has a refractive index of at least 1.67.

Title: Toric lens casting mold arbor
Inventor: BRUKER IZI
IPC: B29C33/42
Filed: 1991-11-27
Abstract: ABSTRACT     The disclosure of this application is directed to injection molding methods and apparatus for the production of casting molds for toric lenses having prism ballast oriented properly with respect to the cylinder axis of the toric curves.     The application discloses the use of a calibrated rotatable ring mechanism within the injection molding body, for producing a slot or other alignment means on the lens casting mold at a point which is offset a predetermined number of degrees from the axis of the toric curve being formed in the casting mold.  When the casting mold containing a newly cast lens is mounted on a precision lathe, the mating of the slot with a permanent ridge on the lathe spud ensures that the mold seats on the lathe at the same established place each time with respect to the position of the cutting tool.     The offset between the toric axis and the position of the cutting tool has already been established, and therefore there is no need for the lathe operator to make any measurements or resetting of the cutting tool.

Title: Volumetric and terrain imaging sonar
Inventor: KOSALOS JAMES G
IPC: G01C13/00
Filed: 1992-05-26
Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for the generation of a three-dimensional image representing structures detected within a volume.  Two dimensional differential phase measurements are made on backscatter signals.  Azimuth, elevation and range are calculated over a statistically large number of spatially diverse backscatter returns and used to construct a histogram of backscatter data. The histogram of backscatter data can be processed with standard image processing techniques to produce terrain maps or volumetric models of the volume of water.  A system constructed according to the methods of this invention is capable of producing a three-dimensional map of the volume insonified without mechanical array scanning or electronic beam scanning.  A combination of two or more volumetric scanning systems can be used to increase the resolution achievable in modelling the volumetric area.

Abstract: A method of welding metal products, at least one of which being made of nickel or a nickel alloy, comprises the steps of generating an arc between the products to be welded serving as a positive pole and a tungsten electrode held by a welding torch serving as a negative pole, emitting a shielding gas consisting of an argon-based mixed gas containing one or both of hydrogen and helium from a confining gas nozzle concentric with the tungsten electrode, thus confining the apparent flaring angle of the arc within 80 degrees, and moving the welding torch along the weld line while feeding the tip of a filler wire to a part of the molten pool directly below the arc.  This method is applicable to the welding of metal products, at least one of which is made of nickel or a nickel alloy.

Title: Indicating apparatus for a coupling
Inventor: BLOOM JOHN J JR
IPC: E02F3/40
Filed: 1990-07-16
Abstract: Certain earthworking vehicles are often provided with the ability to change work implements to enable them to perform a variety of operations. In many instances, the coupling mechanism between the work implement and the frame structure of the vehicle that supports them is designed such that the implements may be mounted and removed quickly. During the mounting of the implement upon the support frame, there is no means by which an operator can be sure that the proper attachment has been achieved. A visual inspection of the mounting apparatus or some sort of test maneuvering of the support frame is required to be sure the work implement is securely attached. The mounting apparatus of the present invention provides a means (84) by which a proper coupling between the work implement (10) and the support frame (13) is positively indicated.  This indication can only be attained when the respective components are aligned in a manner that will allow a proper attachment.
