Abstract: APPARATUS FOR RECEIVING AN AM STEREOPHONIC SIGNAL     ABSTRACT OF THE DISCLOSURE           Apparatus for receiving an AM stereophonic signal of the type having monaural information represented by amplitude modulations of a signal carrier and stereophonic information represented by phase modulations of the signal carrier.  A reference signal generator generates a reference signal that is synchronized with the signal carrier of the received AM stereophonic signal.  In one embodiment, the reference signal generator is a phase-locked loop which generates a reference carrier whose frequency is substantially equal to the signal carrier frequency and whose phase is locked to a predetermined signal carrier phase.  An amplitude limiter limits the AM stereophonic signal to remove amplitude modulations of the signal carrier and thereby produce an amplitude-limited signal carrier. A demodulator demodulates the information represented by the AM stereophonic signal, and a detector is provided to detect if the stereophonic information will be properly  modulated.  A switching arrangement is controlled by the detector to supply the reference signal to the demodulator, whereby the stereophonic information is demodulated, or to supply the amplitude-limited signal carrier to the demodulator, whereby the monaural infor-mation is demodulated.

Abstract: PATENT APPLICATION   entitled: Process for the superficial treatment of a fibrous filtering layer, which is non-woven and highly aerated, forming electret, and application thereof to filters and to breathing masks in particular INVENTOR :    Bernard Thiebault ABSTRACT OF THE DISCLOSURE             The process of the invention consists in smoothing the or each fluffy surface of the layer by exerting a slight friction under low pressure so that the projecting fibres are flattened on the subjacent fibrous mass without the latter being com-pressed, the friction being exerted at a softening temperature such that the superficial fibres are welded together to form a s kin or porous glaze. The smoothing is preferably effected by means of a metal mass whose temperature is between 115 and 150°C. This process may be applied to the outer face of a fil-tering breathing mask constituted by an envelope made of this fibrous material covering a relatively rigid porous shell for protection of the skin; it may also be applied to at least one of the faces of filtering layers equipping    filters of any type.

Abstract: (No. 62) ABSTRACT             Apparatus for forming a sheet metal pulley from a cup-shaped blank in a single hydraulic forming operation. A pair of die holding members supports a plurality of groove-forming inner dies and is movably mounted on a base for horizontal reciprocal movement between open and closed die positions for capturing a pulley-forming blank therebetween.  Tapered pins extend vertically through aligned openings formed in over-lapping shelf members of the die holding members to wedgingly clamp the dies toward each other and to lock them in a hori-zontally closed position.  A ram plate is mounted on a plurality of vertical posts for reciprocal vertical movement with respect to the captured blank.  The ram plate has a top die which exerts axial pressure on the hub portion of the blank during the hydraulic bulging of the blank side wall by a confined fluid within the blank in cooperation with the groove-forming inner dies.  A plurality of pistons mounted on the vertical ram plate cammingly engage mating surfaces provided on the posts and adjacent cam shafts to mechanically lock the ram plate die in a vertically closed position. A burst of high pressure is applied to the trapped, partially formed pulley to final form the pulley by setting the metal of the pulley against the inner dies by exceeding the elastic limit of the metal, eliminating springback after the pulley is removed from the dies. Certain of the groove-forming inner dies are movable vertically independently of the top ram plate and hub die by hydraulic pistons to permit variation in the groove-forming sequence during the pulley forming procedure.

Abstract: ABSTRACT OF THE DISCLOSURE           A shipping container is provided comprising a pallet as the bottom thereof, an inverted identical pallet as the top thereof, and a peripheral sleeve forming load-bearing side walls mating with each pallet via a peripheral sleeve-receiving groove defined by a peripheral rim.  The unitary pallet is configured so that a bottom pallet of one container will mate with the inverted top pallet of a lower container, when containers are stacked, in such a way as to prevent shifting between containers.  The pallets are also self-nesting for transport or storage when unloaded. The containers will stack even if vertically adjacent mutually inverse pallets are rotated 180° in a horizontal plane with respect to each other.  This ability to tolerate a 180° rotation is provided by projecting members and platform members of the pallet feet, oriented so that (i) a 180° rotation of the pallet in the plane of the pallet results in a projecting member/platform member pattern the same as the pattern prior to rotation and (ii) a 180° rotation of the pallet about a center line lying in the plane of the pallet results in a projecting member/platform member pattern which engages the unrotated projecting member/ platform member pattern in mutually abutting relationship. The pallets also have their feet so disposed to permit four-way fork lift entry.  An alternative embodiment is provided wherein said pallets are nestable and stackable at 90° in-tervals of relative rotation.

Abstract: CONTROL MODULE FOR ENERGY MANAGEMENT SYSTEM         ABSTRACT OF THE DISCLOSURE A control module for controlling at least one variable-power-consuming load responsive to data input from local and/or remote locations, utilizes a controller microcomputer having an output setting the gain of a variable gain amplifier.  The variable gain amplifier operates on a substantially-constant output of an oscil-lator to provide, on a cycle-by-cycle or long-term basis, a periodic waveform of controlled amplitude to the at least one load.  The amplitude of the waveform sets the energy consumption/output of the load.  Another data bus facilitates connection of local control means to a control module interface providing local control information to the controller microcomputer, while a third data bus is dedicated to communication with a remote central controller, if used.  The control module includes circuitry for allowing a unique local address to be set for a particular control module, to which unique address the control module responds when a plurality of such control modules are connected in parallel to a central controller.  A fourth data bus connects local sensors, such a photocells, thermistors and the like, through analog-to-digital conversion circuitry to the controller microcomputer, to facilitate control of the local loads responsive to local ambient conditions. The maximum level of the load(s) connected to a control module may be programmably established such that this maximum level can not be exceeded by local and/or remote commands, until the maximum level is altered.
