Abstract: SEAL-ACTUATING MECHANISM FOR A WALL PANEL     ABSTRACT          A seal-actuating mechanism, which when mounted in a wall panel of the type having channel-shaped opposed frame members can be installed, replaced or repaired without removing the exterior finished surface of the wall panel.  The seal-actuating mechanism includes a rotatable shaft mounted between the opposed frame members and an operator member including pivot lever means is mounted on each end thereof.  At least one tension member is disposed in the cavity of each frame member, one end of which is coupled to the pivot lever means, and the other end is coupled to the shiftable seal assembly so that when the shaft is rotated the seal assembly is shifted respectively from an extended unlatched position to its retracted latched position.

Abstract: Abstract:   A position-measuring transformer comprising a pair of confronting relatively movable supports (12, 14) upon the confronting faces (16, 18) of which lie patterns of conductors (26, 50).  The conductors (26, 50) on the respective supports (12, 14) are dimensioned, configured, and positioned in such a way that portions of the conductors of one support confront portions of the conductors of the other support.  When the conductors of one support are energized, a coupling effect is produced in the conductors of the other support.  This coupling effect varies as a function of the relative position of the conductors, i.e., the relative position of the support.  The energized conductors comprise a pattern of strip-like conductors (30, 88, 116) placed side by side.  The conductors in which the coupling effect is produced are of two configurations.  The "fine data" pattern comprises strip-like conductors (116) placed side by side in a pattern similar to that of the energized conductors (30).  The resultant coupling effect varies substantially sinusoidally and provides a "fine" measurement of the relative position of the coupled strip-like conductors.  The "coarse data" pattern comprises conductors (88) which confront the energized conductors (30) along a portion (128) of the energized conductors, the length of this portion (128) varying monotonically as a function of the relative position of the supports.  The outputs of the "fine data" and "coarse data" conductors are combined to provide a highly precise measurement of the relative position of the supports (12, 14).

Abstract: ABSTRACT OF THE DISCLOSURE         Residual noise control is provided on telecommuni-cations links, which are at least partly 4-wire, by means of a variable threshold centre clipper applied to the out-put of an echo canceller.  The threshold of the centre clipper is varied in accordance with the magnitude of an echo estimate generated by the echo canceller.  In order to prevent mutilation of near end speech the clipper is disabled when such speech is detected.  However, the echo canceller remains in circuit to allow control of echo even during doubletalk.  The clipper's threshold may be con-trolled in response to the instantaneous modulus of the echo estimate.  Alternatively, the echo estimate may be fed to a modulator and filter to provide a short term filtered version of the echo estimate which allows con-trol of other components of residual noise.

An operator chooses the total number of a batch of the articles from which the random selection is to be taken, as well as the total number of samples of the articles to be taken from the batch. A series of random numbers, each representing an incremental advancement of the series of articles, is developed when a reset button is actuated by the operator which interrupts a very long sequence of numbers held in the memory of a micro-computer, thereby establishing a starting point. A sensor senses the articles as they pass a predetermined station, and those articles are removed from the advancing series which relate in the sequence to each randomly generated number. Information is displayed which relates to the number of the batch, the number of samples, and the number of articles still to pass the predetermined station immediately prior to the next article scheduled for removal. The apparatus and process can also be used to remove random samples from an advancing flow of fungible material.

Abstract: ABSTRACT OF THE DISCLOSURE:           In a method for the continuous casting of metal, in particular steel, in the form of strips or thin slabs, the molten metal is poured into a shaping cavity having two arcuate cooled wide side-walls which rotate in the direction in which the strand moves, and two stationary cooled narrow side-walls.  The narrow side-walls engage between the two arcuate wide side-walls.  To prevent defects in the strand and breakdown of the casting operation, the narrow side-walls of the shaping cavity are thermally insulated in a first portion as seen in the direction in which the strand moves.  In a second portion the narrow side-walls have high thermal conductivity over the entire distance between the wide side-walls, the second portion being disposed in a substantially parallel part of the shaping cavity between the wide side walls.

There are a plurality of ports through said flat plate valve member.  Reciprocation of the floating valve member in the wall closes and opens communication through the ports between the supply of combustible mixture and the combustion chamber.  A pressurized combustible mixture is fed to the second side of the floating valve member through supply means having substantially smaller cross section area than the second side of the floating valve member.  The device includes means for igniting and combusting the combustible mixture in said combustion chamber to produce pressurized combus-tion gases.  The floating valve member is reciprocated by said pressurized combustible mixture in communication with the second side and the pressurized combustion gases in communication with the first side to regulate the flow of combustible mixture into said combustion chamber.
