Abstract: A process and apparatus for controllably registering two continuously moving layers of material is provided. One of the layers is elasticized and has a plurality of reference marks representing a plurality of separate and distinct components, and the other of the continuously moving layers has a respective plurality of components thereon. The process and apparatus controls the distance between reference marks to a selected distance, and controllably registers each reference mark to a respective component of the continuously moving second layer.

Abstract: An apparatus for controllably registering two continuously moving layers of material is provided. One of the layers of material has a plurality of reference marks representing a plurality of separate and distinct components, and the other of the continuously moving layers has a respective plurality of different components thereon. The apparatus controls the distance between reference marks to a selected distance, and controllably registers each reference mark to a respective component of the continuously moving second layer. An article is provided in which a graphic is controllably registered within a designated area thereof.

Abstract: A process and apparatus for controllably registering two continuously moving layers of material is provided. One of the layers comprises a permanently settable material, and has a plurality of reference marks representing a plurality of separate and distinct components, and the other of the continuously moving layers has a respective plurality of different components thereon. The process and apparatus controls the distance between reference marks to a selected distance, and controllably registers each reference mark to a respective component of the continuously moving second layer.

Abstract: A process and apparatus for controllably registering two continuously moving layers of material is provided. A continuously moving first layer has a plurality of components thereon, and a continuously moving second layer has a plurality of reference marks representing a respective plurality of components thereon. The process and apparatus control the distance between reference marks of the second layer to a selected distance, and controllably registers each reference mark of the second layer to a respective component of the continuously moving first layer.

Abstract: Making fibrous substrates. The method consists for a given substrate thickness in adopting a displacement step size that varies in application of a step size reduction relationship adopted to impart constant thickness to the various superposed and bonded-togehter layer thickness making up said substrate thickness. Application to manufacturing friction parts.

Abstract: A two stage pumping unit for evacuating tubes, and in particular television ubes. A primary mechanical pump is air-cooled and is connected in series with an oil diffusion pump. The inlet for the stem of a tube to be evacuated has a sealing ring and between the sealing ring and the diffusion pump there is a baffle. Between the two pumps there is an oil condensation device and an oil trap. The trap, the condensation device, the oil diffusion pump, the baffle and the sealing ring are arranged for cooling by forced air.

Abstract: A unitary molded or cast bicycle frame formed by a plurality of elements of open cross-section and integral with each other to form a unitary structure, such elements including a top crossbar, a steering tube at one end, the front end, of the crossbar, a transverse crank gear case below and spaced downwardly from the top crossbar, a bottom member extending from the steering tube to the crank gear case, a two-armed, wheel receiving fork extending rearwardly from the crank gear case and having wheel spindle receiving openings at the rearward ends of the arms, a pair of struts extending from the arms of said fork adjacent said openings to the opposite, rear end of the top crossbar and a strut member extending from said struts at portions thereof intermediate said top crossbar and said openings to the arms of said fork adjacent said crank gear case. A saddle or seat tube or opening is provided at or adjacent the juncture of the struts and the top crossbar.

Abstract: A steering fork for cycles, e.g., bicycles, motorcycles, etc., preferably moulded from a plastics material, having an upper stock portion with bearings for receiving the cycle frame pivot pin and with a handlebar mounting bracket and having a pair of downwardly extending, spaced apart arms for receiving the cycle front wheel therebetween. The arms have openings and means for mounting brake jaws in the arms so that brake pads on the jaws can pass through the openings and engage the wheel rim. The wheel axle is received in openings at the lower ends of the arms and preferably, the openings are at least partly surrounded by tapered projections receivable in recessed nuts on the axle. The stock portion has one or more tubular portions for receiving one or more handlebar mounting bracket extensions and means for clamping the extensions at the desired height.

Abstract: An injection nozzle for plastics material comprises a rear tubular body and a hollow front body with a nozzle orifice at one end and detachably connected to the rear body at the other end, an elongate body being provided within the front and rear bodies and mounted thereon by having radially extending arms extending into an annular V-shaped groove formed by chamfers in the engaging surfaces of the front and rear bodies, the elongate body carrying a slidable closure member biassed to close the nozzle orifice.

Abstract: The structure comprises a turbo-molecular pumping element providing a very moderate compression ratio and a rotating drum type pumping element equipped with an interchangeable stator or drum. These two elements are mounted in series and driven in a rotating movement by a single shaft. On the interchangeable part, parallel helical grooves whose depth depends on the molecular mass of the gas to be pumped are formed.
