Abstract: Reta alloys with improved properties Abstract :      An aluminium bearing beta copper alloy that on heating to a first temperature shows a transition from an (alpha + beta)-region, an (alpha + beta + gamma)-region or a (beta + gamma)-region to a beta-region.    Its average grain size is less than 200µm and it contains aluminium bearing precipitates, e.g. Co-Al-precipitates, the average size of which is less than 10µm and which are insoluble in the alloy below a second temperature that is higher than said first temperature.    The fine grain structure guarantees an ex cellent mechanical and thermomechanical behaviour of the alloy, while the aluminium bearing precipitates guarantee that this structure and hence the advantageous behaviour of the alloy is maintained as long as the alloy is not heated to said second temperature.

Abstract: ABSTRACT A method of functional addressing which may be employed with a multiplexed data bus having a plurality of data processing units coupled thereto.  A function code is generated and made part of a transmitted message. Units receiving the transmitted message apply the function code to the address lines of a random access memory and read the contents of the memory at a location indicated by the function code.  The contents stored at each memory location are indicative of whether or not that type of message is accepted or disregarded by the receiving unit.  Also, a method of changing the contents of the memory, and hence the routing of messages between units, is disclosed.

Abstract: RING PURGING METHOD                 Abstract of the Disclosure A method and apparatus is described for initializing non-synchronous peer-to-peer data communication rings, and for effecting error recovery in such networks   In non-synchronous ring networks the stations derive reception clocking synchronism from data signals sent by preceding stations and independently derive transmission clocking synchronism from a local source of oscillations which is not synchronized to the received signals.  During normal operation, each station monitors its reception clocking condition, and upon detecting a loss of synchronism conducts a recovery operation designed to restore data integrity to all stations.  This operation involves the station timing out for a first predetermined time interval, and then re-sampling its receiving clock to determine if the loss condition is "transient" or "persistent".  If the condition is transient the station operates in a purging configuration for a second predetermined interval of time and then resumes normal operation.  The purging operation removes erroneous data signals from the ring.  If a loss condition is persistent the station operates first in a "bypass" configuration then in the purging configuration and then resumes normal operation.  This serves to restore reception clocking in temporary alignment with the local transmission clock source.  If the station fails to develop synchronism it repeats the foregoing recovery procedure.

Abstract: ABSTRACT OF THE DISCLOSURE           An exhaust air valve for placement in a ventilation conduit through which air is exhausted from a space to be ventilated.  The valve has a casing with a concave seat surface facing upstream of the flow through the conduit and having a central valve orifice.  A convex valve element cooperates with the seat surface and when the valve is closed engages the seat surface along a line of contact surrounding the seat.  The curvature of the respective surfaces is the same, at least along the line of contact to ensure a tight closure of the orifice by the valve body.  When opening, the valve body slides along the curved surface and the upstream surface of the valve body exposed to the flow is also convex to guide the flow toward the center of the orifice.  Several embodiments are illustrated including valves with cords for remotely controlling the valve and heat-sensitive tripping mechanisms which automatically close the valve in the event of a rise in temperature above a preset level.  The closing movement may be pivotal about a pivotal connection maintaining the valve element in sliding contact with the valve seat or may be a sliding displacement longitudinally of a slot in one of the elements.

Abstract: ABSTRACT OF THE DISCLOSURE A roofing structure, for  forming  for  example  a vault, possibly transparent or translucent, is adapted to cover a zone located between two supports generally parallel in a longitudinal direction. This structure is  composed of a plurality of juxtaposed roofing plates located at one or more levels, and of hoop elements disposed transversaly between the two longitudinal supports. Each of these hoop elements is constituted by at least two elementary hoop elements comprising a  lower hoop element and an upper hoop element superposed  on the lower hoop element. The trans-verse edges of the roofing plates are engaged between the lower and upper hoop elements of each pair.        The roofing structure comprises means for provoking the deformation of one of the superposed  hoop elements by applying it under pressure  against the other and thus ef-fecting gripping of theroofing plates between the superposed elementary hoop elements, without any seal .

Abstract: ABSTRACT         The electrically operated clutch controlling operation of the compressor is regulated by a damped pressure switch. The pressure switch has a diaphragm which moves in response to pressure variation to actuate the switch.  The force acting on the diaphragm is opposed by spring force.  The housing is provided with a damping chamber between the diaphragm chamber and the restricted passage in the inlet. The restricted passage is the clearance between the hole drilled in the metal insert and the wire fixed in the hole. The restriction is selected relative to the damping chamber so the switch will not cycle more than four times per minute when sensing pressure at the outlet of a finned coil evaporator in an automotive air conditioning system operating under light load.

A substantially spherical mirror is dis-posed in the beam path of the system between the first (B) and the second (A) areas of reflection. A radiation detector (D) is disposed at the end of the beam path. A beam converging optical element such as a positive lens or a substantially spherical mirror, is disposed in the beam path between the first substantially spherical mirror     and the second area of reflection (A). Means                       are provided to form a real image of the radiation detector (D) in the beam path at a position between the first substantially spherical mirror     and a location so close to the beam converging optical element that the element serves as a field element for this location of the real image.

The simplified circuit uses half as many memory elements as the prior art circuit and employs Boolean identities to simplify the logic elements encoding the data.  In a preferred embodiment, the circuit is implemented using emitter-coupled logic.  If necessary, the capacitance required by resistor-capacitor networks used to eliminate race conditions may be formed between a planar conductor on one side of a circuit board on which the circuit is laid out and a circuit element on the other.
