The first compartment has a series of ultra-violet sources 26 interdigitating with the plates to expose these and a hot air supply 34, 35 for driving solvent from the plates. The second compartment has spray means 29 interdigitating with the plates to spray detackifying solution thereon and a hot air supply 34, 35 for drying the plates after detackifying.

Abstract: A reinforcement belt for a pneumatic tire includes at least three superpositioned plies of filiform elements. A first ply having two free lateral edges has at least one lateral edge portion folded over to create a skirt with the balance of the first ply forming a main portion having an axial width substantially equal to the axial width of the reinforcement belt. The filiform elements in this first ply are of aromatic polyamide composition and have a high modulus of elasticity. A second ply extends parallel to the first ply over an axial distance at least equal to the axial spacing of the two free lateral edges of the first ply. The filiform elements in the second ply may be either of aromatic polyamide or steel composition. A third ply of filiform elements of steel extends into the median zone of the belt and has an axial width which is less than, equal to or greater than the distance separating the free edges of the first ply. Various orientations of the plies are disclosed.

Abstract: This invention relates to a cleat (sometimes referred to as a "rail fastening clip") utilized for the purpose of positioning and retaining a rail to a sleeper (sometimes referred to as a "tie"). In this invention a rail cleat comprises a spring plate having a configuration such that when retained at an intermediate locality, a rail-bearing end bears against the upper surface of the foot of the rail while a tail bears against a sleeper or a bearing pad thereon, an upstanding loop standing upwardly from a sleeper, and a locking pin passing through the loop and bearing against the intermediate locality of the cleat so as to urge the cleat downwardly against the foot of the rail.

Abstract: A multipolar resolver is so constructed that the need of the conventionally indispensable coil on the resolver rotor is eliminated by providing a center coil on a stator, and 5n or 3n rotor poles and 4n stator poles are provided where n is a positive integer. Sine and consine coils are wound on the stator poles alternately, thus simplifying the construction of the multipolar resolver.

Abstract: A particle color discriminating apparatus including a vibration feeder for feeding particles to be discriminated, a shooter for causing the particles from the feeder to flow downwardly, photoelectric detecting means located in the vicinity of a path of flow of the particles in a predetermined locus, an air ejector arranged beneath the photoelectric detecting means and control means for controlling the actuation of the air ejector in accordance with an output signal of the photosensitive detector is provided with an automatic control device operative to control the amount of particles supplied by the vibration feeder in accordance with changes in the proportion of particles distinct in color from the particles of interest in the particles supplied.

Abstract: Apparatus for treating fabric by beating while the fabric is in the spread or flattened state, particularly for use in a process and system for washing the fabric. The apparatus has a large number of beating bars arranged in groups each of which being adapted to effect a beating, in cooperation with beating anvils, on the fabric which is carried and fed by an endless rubber base running on the beating anvils. The driving mechanisms for the feed of the fabric and for the beating are operatively connected such that the feed and the beatings are made alternately. For washing the cloth, the cloth is immersed in the solution of a detergent, and is then beaten by the first group of beating bars. Subsequently, the fabric is beaten by the second group of beating bars under application of washing with hot water or water. The apparatus of the invention can treat thin fabrics such as gauze, and can ensure a high soft feel or touch of the finished fabric, due to the application of the beating.

Abstract: Apparatus for irradiating a surface, for example, for irradiating a photopolymer printing roll with ultra-violet light. The apparatus utilizes elongated radiation sources with individual reflectors directing the radiation to crossed planar mirror systems which re-direct the radiation toward the printing roll. The part of the mounting means for each radiation source at the end of the source between the sources is shielded from its respective mirror system by the rear surface of the other mirror system to expose the roll to substantially uniform intensity of radiation along substantially the entire length of the roll.

Abstract: An electromechanical electret transducer suitable for push-pull operation includes multiple vibratory diaphragms acoustically coupled to each other to increase the output sound pressure. Since the diaphragms physically shield the stationary electrets, the adverse environmental effects on the charge stabilities of the electrets are minimized.

Abstract: A marker nib having a tapered tip portion, a substantially cylindrical barrel portion, and a trunk having a frusto-conical portion of smaller maximum diameter than the barrel portion and extending therefrom. The nib can be manufactured in a mold requiring simple tooling and having a parting line for the mold segments at the junction of the barrel portion with the trunk.

Abstract: The ejecting member is interposed between two blade elements of a two-edge shaving blade unit in a manner to be retractably moved forwardly to eject shaved hair particles and other matters deposited in and clogging the space between the cutting edges of two blade elements. The ejecting member has an integral construction which includes an outer frame portion defining the outer profile of the ejecting member, a substantially quadrilateral aperture having at least one discontinuity and defining at its outer sides the inner edges of the outer frame portion, an inner island portion fixedly cramped between two blade elements and defined by the inner sides of the aperture, and a resilient bridge portion constituted by the discontinuity of the aperture and resiliently connecting the inner island portion to the outer frame portion.

Abstract: A heavy duty pneumatic tire is provided with bead cores having polygonal cross-sectional configurations. The bead cores are composed of a multiplicity of wires arranged in densely superpositioned parallel layers which are situated on conical generating lines whose common axis coincide with the horizontal axis of the pneumatic tire and whose angles of opening are approximately 10.degree.. The axially innermost and axially outermost wires in specified radially inner and radially outer layers lie on centerlines forming angles within selected ranges with the conical lines.

Abstract: Apparatus for treating the surfaces of cylindrical objects in a number of sequential steps and, more particularly, for treating photopolymer printing cylinders in alignment with separate treatment bays. The cylinders are individually rotated in each compartment about their individual axes.

Abstract: A system for the automatic management (detection and control) of tool life in a numerically controlled machine tool having means for automatically measuring the dimension of workpieces and correcting the tool offset of a cutting tool depending on wear on the cutting tool. In the system, the mechanical deformation error component (radial deviation component of a spindle of the machine tool) due to heat is removed from the amount of tool offset value (tool feed position compensation) so as to accumulate solely the net tool wear component, and the cutting tool is exchanged when the accumulated value attains a predetermined setting.

Abstract: A method of making a notched variable speed belt or a notched V-belt by placing the layers of the belt around a smooth cylindrical mold, placing an endless elastomeric sleeve having ribs on its inner surface, around the mold and layers thereon and applying heat and pressure to urge the sleeve against the belt layers to form a cured belt slab with molded grooves therein. The cured belt slab may then be cut into individual notched V-belts or variable speed belts of high quality.

Abstract: A vehicle has a main frame which is adjustable for height, and a swivel frame pivoted to the main frame. There are at least three driven saws on the frames, and at least one of those is on the swivel frame. The saws are arranged to cut canes which extend respectively upwardly, outwardly and inwardly of a vine which is carried on a trellis wire.
