Abstract: ABSTRACT OF THE DISCLOSURE:             Practice cartridge with plastic projectile or projectile replication in which the projectile or the projectile replication is shaped in one piece on a plastic casing open at the rear end, which is inserted into a metal cartridge casing open at the forward end.  The cartridge casing with tip-stretched casing shoulder and neck is also produced open at the rear end so that the plastic casing is insertable from this end into the cartridge casing to be positioned tightly at its inner wall in such a manner that the rear end of the projectile is positioned flush with the mouth of the neck.  In the rear end of the cartridge casing there is inserted a separate metal base piece which closes this off tightly to the rear.  With such a combination a clean separation of the projectile from the neck is achieved upon firing of the practice cartridge.

Abstract: ABSTRACT     A poultry-harvester for use in a poultry house comprises two contra-rotating rotors arranged side by side with the flexible fingers of each rotor abutting and/or intermeshing with the fing-ers of the other rotor.  In operation, as the harvester is driven towards the birds to be harvested, the two rotors are rotated in opposite directions to one another so that the fingers co-operate to carry birds between the two rotors and deposit them on the conveyor belt.  In another embodiment, a third pick-up rotor is arranged in front of and co-operating with the other two rotors in a triangular formation and the conveyor belt deposits the birds on a turntable at the rear of the harvester.  In this latter case, the support frame for the conveyor belt is preferably able to scan back and forth around an arc to accelerate the harvesting opera-tion and the third rotor is rotated in the direction of the scan.

Abstract: INVENTION: MONITORING SYSTEM INCLUDING A NUMBER OF MEASURING            STATIONS SERIES CONNECTED TO A SIGNAL LINE     ABSTRACT OF THE DISCLOSURE     In the monitoring system which is intended for buildings, rooms and objects a multitude of measuring or detecting and signalling stations are series connected to a central signal station.  Each of the detecting and signalling stations transmits information about its instantaneous state, which may be any one of standby, warning, alarm, malfunction, to the central signal station by means of an electronic circuit member.  The electronic circuit member affords the following advantages: identification of the number and of the location of the detecting and signalling station in the case of changes in the state of the detecting and signalling station; detection and localization of malfunctions such as a short-circuit or an interruption in the signal line; cut-off of the short-circuited signal line section from the remaining signal line; saving of installation expense; greater flexibility in the evaluation of the states of the detecting and signalling stations and in the initiation  of  appropriate  measures  or  counter-actions; operation of control devices via the signal line; monitoring of the electronic circuit member.

Abstract: DIGITAL CODE CONVERTER            Abstract Accumulation of distortion possibly resulting from multiple digital code conversions is prevented by including in an ADPCM-to-PCM decoder (100, FIG. 1 or 600, FIG. 6) an arrangement (119, FIG  1 or 601, FIG. 6) for making a trial transmission of the resulting PCM sample (?(k)) to obtain (via 209, FIG. 2) a composite noise value (.alpha.(k)) for the PCM sample (?(k)).  The composite noise value includes noise components resulting from both quantizing the code word and truncating digital signals used in the decoder and subsequent coder.  The composite noise value is evaluated (via 211) to determine whether adjustment of the PCM sample value (?(k)) is necessary.         In one embodiment (FIG. 1, 100), a reconstructed linear version (Yr(k)) of the PCM sample is adjusted (via 216, 218, 220 or 221) when the composite noise value (.alpha.(k)) is not within the ADPCM quantizer interval for the ADPCM sample (In(k)) being converted to PCM.  The amount of adjustment is dependent on the PCM quantizer interval (214) that the reconstructed signal (Yr(k)) falls in and whether the ADPCM sample is in saturation, i.e., the most positive (215) or negative (217) ADPCM quantizer interval, or not in saturation (219).         In another embodiment (FIG. 6, 600), the decoder (600) PCM output sample ?(k)) is adjusted, if necessary, up or down one PCM quantizer interval (via 802 or 803) when the composite noise value (.alpha.(k)) is not within the quantizer interval decision levels of the ADPCM sample received by the decoder 600.

Abstract: Abstract A display assembly comprising a plurality of modules each having a display area particularly suitable for mounting eyeglass frames.  Each module has spaced vertical edges having male and female hinge portions permitting successive mating of adjacent modules.  The male hinge portion has an elongate vertical member which is received in a vertically extending opening defined in the female hinge portion.  The adjacent modules are joined by aligning the male portion with the opening in an adjacent panel and advancing the modules vertically, each toward the other.  The female hinge portion defining the opening has a plurality of tabs which are extendable through cutouts in the wall of the adjacent module with the male hinge portion.  The passage of the tabs through the cut outs extends the range of relative pivoting between adjacent modules and permits arrangement of the modules in configurations from flat to continuous inter-connection with the use of three modules.  The invention contemplates vertical stacking of modules with corres-ponding hinge connections between adjacent columns of modules.  A horizontal seam is formed between adjacent vertical modules and is misaligned with seams on the adjacent column of modules so that there is no continuous line of weakening.  To afford additional rigidity to the structure, each module is fit with a reinforcing plate and a unitary member interconnected with each of the plates.  This arrangement also permits a formation of a rigid base to which a pedestal or other suitable stand can he attached.

Abstract: ABSTRACT A self energizing pipe gasket includes a base and arm configura-tion projecting therefrom which cooperates with the base when pipe sections are assembled to cause the lip or sealing edge of the arm to kick away or distend toward the sealing surface of the pipe. To facilitate this action a harder insert is provided in the base in the form of a reinforcing ring providing a less compressible surface for the arm to react against. The ring also stiffens the gasket making it more difficult to dislodge upon assembly of the pipe sections enabling higher compression forces and assuring that the gasket does not go under or below the minimal compression requirements to form a sound flexible yet fluid tight seal.

Abstract: TIMED FLOW CONTROL VALVE ASSEMBLY                 ABSTRACT OF THE DISCLOSURE           A flow control valve assembly is provided for timing and regulating fluid flow from a valve inlet to primary and secondary fluid outlets.  The valve assembly comprises a regulator valve which, upon initiation of fluid flow to the valve assembly, is spring-biased to open the primary and secondary outlets and to modulate the primary outlet flow in a manner maintaining the secondary outlet flow at a predetermined minimum fluid pressure.  Upon elapse of a predetermined time interval, a timer assembly responsive to the secondary outlet flow triggers an alteration in the spring bias acting on the regulator valve to permit fluid pressure at the valve inlet to shift the regulator valve to a position closing the secondary outlet and fully opening the primary outlet for the remaining time of a fluid flow cycle. When fluid flow through the valve assembly is halted, a return spring  resets the regulator valve to its initial state.          In a preferred operating environment,  the valve inlet is coupled to the discharge side of a swimming pool circulation pump which draws pool water through a filter unit.  The primary outlet of the valve assembly is coupled to a return conduit for recycling filtered water to the swimming pool, and the secondary outlet is coupled to a water-powered in-the-pool clean ing device.  During a normal filtration cycle, the valve assembly initially supplies water to the cleaning device at a predetermined minimum pressure for a selected time interval and then automatically switches state to halt operation of the cleaning device and to recirculate filtered water to the pool through the return conduit.
