Abstract: ABSTRACT OF THE DISCLOSURE An electrophotographic printing machine in which color transparencies are reproduced,  The photoconductive member of the printing machine is charged to a substantially uniform level.  A screen member is positioned closely adjacent to the photoconductive member.  The screen member comprises a transparent sheet having a plurality of spaced, opaque regions thereon.  A slide projector projects a light image of the color transparency through a filter and screen member to form a modulated single color light images.  A composition frame is disposed on a transparent platen through which the light image of the color transparency is protected.  The composition frame defines an opaque border  extending outwardly from the light image of the color transparency transmitted therethrough.  A defines lens is mounted on the composition frame so that the light image of the color transparency passes therethrough.  The composition frame is also illuminated so that a light image thereof is transmitted through the screen exposing the charged portion of the photoconductive member.  In this way, a combined modulated light image of composition frame and transparency is recorded so as to produce a combined electrostatic latent image corresponding to both of the foregoing on the photoconductive member.

Abstract: ABSTRACT  OF  DISCLOSURE      The invention relates to a stopper with valve for a storage battery which permits the gases evolved by the storage battery to escape only above a precise specific pressure higher than the atmospheric pressure.     The valve includes a diaphragm clack maintained gripped in a fluid-tight manner, at its periphery, between the body of the stopper and a hood which covers a calibrated spring normally keeping the valve closed.  The hood is secured on the body solely by ratchet engagement of these two members which have corresponding frustoconical surfaces and of which at least one is deformable.     The stopper with valve is for application to fixed or starting storage batteries in order to lessen the consumption of water in the batteries.

Abstract: ABSTRACT OF THE DISCLOSURE A process and a device are provided to control the motion of a web of material continuously supplied to a machine operating sequentially.  The process includes continuously leading the web around a section of the circum-ference of a rotating roller arranged on an axle and between two rotary plates.  The plates are also mounted on axles of rotation and are fitted be-tween two side frames.  The roller is offset in relation to the axles of the two plates and the angular position of the roller axle is varied during ro-tation of the plates in such a way as to ensure a full standstill of the web within the machine during a predetermined period.  The total amount of the web, which is arriving continuously, is absorbed.  The roller axle is shift-able into a desired offset position by means of a control screw.  A shiftable counter-weight on the control screw compensates for the weight of the roller. Two pivoting supports connected to the roller permit the angular position of the latter to be varied.  These supports are arranged to correct, the rate of variation of the angular position, depending on the eccentricity of the roller with regard to the plate axles.

Abstract: ABSTRACT OF THE DISCLOSURE         A pipe mate of fiberglass or the like includes a helical reinforcing member bonded to its outer surface substantially over its length with adjacent convolutions spaced with respect to each other.  The reinforcing member or rib includes a filament-wound composite of a series of continuous resin impregnated glass filaments arranged in a bundle and surrounded by a helical fiber having spaced adjacent convolutions.  An alternative construction further includes a core of paper or plastic or metal within the bundle to increase the rib height.  An auxiliary bundle forming apparatus is employed with a filament winding machine so that the same winding  machine and additional lengths of continuous glass fibers drawn from a common storage station may be utilized to form both the fiberglass pipe and the reinforcing rib. A spiral guide may also be used with  the auxiliary bundle forming apparatus and the filament winding machine to add an inexpensive elongated core to the bundle forming a reinforcing rib of increased height.

Abstract: ABSTRACT         An improved variable speed pulley for adjusting the drive ratio between two shafts interconnected through two pulleys and a V-belt.  The variable speed pulley has a hub which is attached through to one shaft with a collet.  A number of keys of generally square cross sections with two opposed chamfered corners are located at each end of the hub in V-shaped axially directed keyways spaced around the periphery of the hub and in correspondingly spaced V-shaped keyways around interior openings through each of two sheave halves to permit axial movement of the sheave halves on the hub.  Bushings retain the four keys within each sheave half.          The bushings and the keys are of a compliant material to prevent fretting corrosion.  The keys engage the bushings to prevent the bushings from rotating with respect to the sheave half and hub.  A helical spring located within a spring housing is compressed between each sheave half and an adjacent one of two retainer rings located in grooves near each end of the hub.  The springs urge the sheave halves together with a predetermined force.  In a modified embodiment of the pulley, one sheave half is fixed to the hub.

The thus obtained monokaryotic mycelium is a novel product and characterized by its extremely high propagation ??te as compared with the known dikaryotic mycelium. Also, the substance extracted from the culture of the mycelium has excellent physiological activities.
