Abstract: CAM ACTUATED EJECTOR MECHANISMS          FOR PRESSES Abstract of the Disclosure A hydraulically actuated ejector mechanism is mounted on a press bed and includes a pair of opposed cams connected to the press slide for vertical displacement therewith.  The cams actuate corresponding followers in the form of hydraulic pistons which operate together to hydraulically displace an ejector member during upward movement of the slide following a metalworking operation.  The cam contours enable timing the ejector pin displacement with the press slide stroke so as to achieve optimum acceleration and deceleration of the stroke of the ejector pin.

Abstract: ABSTRACT           An assembly or organization of longitudinally movable parts having operable connecting means therefor.  This assembly comprises two layers (or multiples thereof) of strips of what are herein termed friction material which comprises in one arrangement, a plurality of short closely arranged straight bristles of nylon or other suitable material carried by a backing therefor of fabric, plastic or other suitable material so that the strips are similar to a rug having a backing with a coat or surface of short, close hairs, fibers, filaments or bristles.  This coating is similar to the bristle arrangement of a brush or similar to the pile or nap of a rug or carpet, and is referred to herein as a plie or nap.  The bristle covered surface of these strips face each other and are spaced apart in substantially longitudinally aligned parallel rela-tionship with at least one of said strips movable linearly or longi-tudinally relative to the other.  In other words, said stripe are movable longitudinally relative to each other.         In the space between these strips is a continuous flexible band or belt of friction material which has the bristles facing outwardly.  The loop ends of the band pass around or over rollers for holding or guiding the band in position with the bristles of oppositely arranged or disposed intermediate parts of the band frictionally interlocking with the bristles of the respec-tive adjacent strips.  When the strips are moved longitudinally or linearly relative to each other, the band also moves longitudinally between said strips.  With such movement, the looped ends of the band have a rolling movement and the bristles of the rolling parts or portions of the band progressively roll into and out of engage-ment with the bristles of the strips thus easily engaging and dis-engaging the bristles of said strips.  However, the parts of the band intermediate the ends thereof, frictionally resist linear or longitudinal movement between said strips, and normally prevent slippage between the band and the strips.  Only a forceful over-riding of the built-in resistance will cause disengagement and when such force is applied, disengagement will occur without de-struction or damage to the parts.         Other types of friction material may be used, such as foam, plastic, rubber or the like, and sheet metal having friction surfaces.

Abstract: Abstract of the Disclosure Method and apparatus of forming glass fibers in which filaments are attenuated through bushing tips in a bushing containing molten glass. Both the environment surrounding and below the bushing and elements dis-posed in the fiber forming region adjacent the bushing are cooled by passing a cooling fluid through a pair of cooling manifolds located on side partitions adjacent the bushing.  The manifolds are below the bush-ing on the partitions, and have inlet sections and outlet sections for flowing fluid in opposite directions.  The manifolds are connected to the elements in fluid transfer relation, and fluid is passed from the mani-folds through the elements in a first direction to thereby cool the ele-ments.  Fluid from the elements is returned to said manifolds, and flows through the manifolds in the opposite direction to thereby cool the environment.

Abstract: ABSTRACT OF THE DISCLOSURE      A method for checking gas analysis devices in respect of their sensitivity and their response and regeneration behaviour with respect to time, wherein a reproducible quantity of the measurement component is produced at a predetermined production rate, for a period of time which is guided entirely or at a constant proportion as a concentration pulse to the measurement element of the gas analysis device.  For the production of the measurement component a chemical or electro-chemical reaction or even a thermal reaction is used.  The time interval can then be conveniently controlled.  A decisive advantage with topic measurement components is that the gas production takes place in all cases for only a short time during the test procedure.

Abstract: Abstract of the Disclosure There is disclosed a system for controlling the generation of low-frequency sound in a motion picture theater, together with the conventional audible sound, in accordance with an input electrical signal derived from the sound track of a motion picture film.  In the prior art, the low-frequency amplifiers were operated in accordance with control signals recorded on the film; spurious control signals could falsely operate these amplifiers.  In the invention, low-frequency ampli-fication is provided only when the low-frequency program information signal itself exceeds a threshold level, thus completely guarding against false operation.  Additional features of the invention include the provision of an adjustable dynamic response for the low-frequency signal path, adjustable attack and release times for the low-frequency pre-amplifier, lamps for automatically indi-cating the source of a malfunction, and test generators which facilitate a theater installation without the need for excessive play of a test film.
