Abstract: ABSTRACT OF THE DISCLOSURE:     The object of the invention is to provide an audio-conference system in which the acoustic residual level due to self-priming is totally eliminated in the transmit channel, which, as a corollary, allows any amplification of the audio-frequency signals transmitted.  After preamplification, the audiofrequency signals coming from each group of a specific number of microphones equidistributed around the center of the table are given a phase shift which is equal for a given micro phone to the polar angle of the microphone around the table.          If the number of microphones is an even number, the microphones are grouped by pairs of two microphones diametrically opposite with respect to the loudspeaker assembly.  The of the micro-phones of the pair is connected directly to a mixing circuit and the other microphones of the pair is connected through a 180° phase shifter to the miwing circuit.  Thus, the components of the signal resulting from the coupling between the loud-speaker and the microphones are cancelled during the mixing operation of the two output signals of the microphones.  Another arrangement prevents the cutting short of a conferee who has begun to speak.  The identification device associated with a table in an audioconference system complying with the invention is not based on the comparison of the acoustic levels of the speakers' voices but, on the contrary, on the intervention speed of the speaker wishing to take the floor.  In other words, once a speaker begins talking with a voice the acoustic level of which is above a first predetermined acoustic threshold, he will keep his turn to speak so far as his voice is above a second predetermined acoustic threshold lower than the first threshold whatever the acoustic levels of the other speakers' voices.          In addition, the detection assembly makes it possible not to change the identification of the speaker during speaking when only brief interruptions occur in the audiofrequency signal from the speaker corresponding to intervals between syllables or words.

Abstract: ABSTRACT OF THE DISCLOSURE      A scientific processing unit includes a microprogrammable arithmetic processing apparatus for performing floating point arithmetic operations with operands in long and short form.  The apparatus includes a microprogrammable control section and a plur-ality of microprocesso-arithmetic and logic unit chip stages org-nized into two sections and carry look-ahead circuits coupled thereto.  One section includes a predetermined number of series-coupled stages connected to process exponent values or long mantissa values.  The other section includes another predetermined number of series coupled stages connected to process short mantissa values.  Control circuits interconnect the stages of both sections and connect to the carry look-ahead circuits and to the micropro-grammed control section.  During the performance of an arithmetic operation, the control circuits in response to signals from the control section, selectively split the two sections and inhibit the propagation of carries generated by the carry look-ahead cir-cuits for operation of both sections independently and as a single unit as desires for efficient execution of the arithmetic operation.

Abstract: ABSTRACT There is provided an "open" type clamp constructed from a wound metal strip with two ends.  The strip has a first radial ear near one end of the strip, and a second radial ear near the other end of the strip.  The first ear is bent over with respect to the strip so that the strip continues beyond it as a first extension directed along the periphery of the clamp and at least spanning the distance which separates the two ears.  The second ear is provided with an extension which maintains a distance from the periphery of the clamp which is nearly equal to the height of the first ear.  At the end of the last-mentioned extension is an end portion which is bent inwardly with respect to the clamp, and which is adapted to engage the first ear in order to securely fix the clamp about an object without any permanent deformation of the ears.

Abstract: ABSTRACT OF THE DISCLOSURE      A hydraulic board-laminating press comprises a series of laterally aligned hydraulic clamps supported in an inclined plane, each clamp having one fixed and one movable clamping jaw defining an upwardly opening mouth for receiving boards.  The positions of the fixed jaws are adjustable along the inclined plane for providing camber in the beam produced. A series of infeed conveyor arms spaced along the lower side of the press deliver boards, adhesive-coated on one face, edgewise and one at a time into the mouths of the clamping jaws.  An outer section of each conveyor arm can be extended and retracted toward and away from the clamps and can be raised and lowered so that the outer ends of the arms deliver boards into various positions within the space between jaw pairs to stack boards within the jaws along the inclined plane of the clamps.  When the clamp spaces are filled with multiple stacks of boards, a low clamping pressure is applied to the stacks through the clamping jaws in a direction paralleling the inclined plane.  Then overhead alignment bars operated by hydraulic pressure are lowered between adjacent clamps to apply edgewise squaring pressure to the board stacks within the clamps.  While the alignment bars continue to apply a squaring pressure, a high bonding pressure is applied to the stack through the clamping jaws and maintained until the adhesive between boards has set.

Abstract: PRESSURE GAUGE CONSTRUCTION Abstract of the Disclosure Pointer zero adjustment in a pressure gauge is effected by means of a shaft (50) centrally extending laterally inward of the casing from a supportive centering flange (40) on the inside face of the crystal (10).  A Bourdon tube (44) is radially coiled concealed from view through the crystal (10) about a pressure sealed rear por-tion of the shaft (50) to which it is rotationally secured. The pointer unit (42) is of a more or less U-shaped cross section with a tubular center (48) loosely supported on the shaft (50) juxtaposed to the crystal (10).  The front pointer formation (42) simulates a conventional pointer appearance while its rear formation (52) is rotatably linked to the free end (56) of the Bourdon tube for in-curring operational displacement therewith.  On removing a detachable cover (37) from over an aperture (34) in the crystal coincidingly located opposite the shaft end there-at, access is provided for an external tool (78) to opera-tionally engage a tool receiving hex socket (38) in the shaft end.
