Abstract: Un appareil à électrode rotative (10) pour produire des poudres métalliques comporte une chambre (14) conçue pour maintenir une atmosphère régulée, contenant une première électrode (30) installée pour effectuer un mouvement de translation et de rotation, une seconde électrode (48) consistant en un disque consumable fixé pour effectuer un mouvement de rotation par un mandrin (42) et un canon à plasma (29) utilisé pour créer un arc électrique transféré (50) entre la première électrode (30) et une partie périphérique de l'électrode discoïdale (48) afin de produire des poudres qui sont de préférence sphériques et de tailles petites et uniformes, par exemple entre 50 et 500 microns. On fait tourner le mandrin (42) à une vitesse suffisante pour centrifuger les parties fondues de l'électrode discoïdale (48) et on en effectue la régulation au moyen de la commande de vitesse (62) qui fait varier la vitesse de rotation du mandrin (42) inversément avec le diamètre de l'électrode discoïdale (48). Il en résulte une force centrifuge constante et des sphères métalliques de taille et de qualité uniformessont ainsi produites. Un moniteur de disque (60) contrôle le diamètre de l'électrode discoïdale (48) en recourant à un dispositif photoélectrique monotonique comportant une source de rayonnement (160) et un détecteur (162).

Abstract: The conveyor has underfloor rail profiles (8) in which transport units (1) are guided. The latter have a platform (2) and a chassis provided with wheels (5) arranged in pairs. Between the rail profiles (8), drive wheels (38-42) are arranged which are in drive connection with a drive (19) by means of flexible drives (43-46), said drive being connectable and disconnectable by means of a clutch (30). A strip which is under spring force and is pressed on the drive wheels (38-42) is arranged on the underside of the transport unit (1). If the drive wheels (38-42) are coupled to the drive (19), the transport unit (1) is moved. As a result of the frictional engagement between the drive wheels (38-42) being separated from the wheels of the flexible drives (43-46), large loads can be reliably transported. <IMAGE>

Abstract: The invention relates to a tube coupling (1) for connecting a tube portion (2) of synthetic resin to another conduit element with resistance to tensile stress in such a way that said tube portion is firmly held to resist high tensile forces due to shrinkage of the tube conduits or other high tensile forces on the one hand, whereas said tube portion is clamped within the coupling in such a way that the synthetic resin thereof is not overloaded by clamping forces. This is achieved by holding the tube portion of synthetic resin by a combination of a grip ring (6) and an elastic sealing ring (8).

Filed: 1985-08-30
Abstract: The invention relates to a root extraction circuit comprising a plurality of n sub circuits, the m th  sub-circuit thereof consisting of m+ add/subtract cells. The two add/subtract cells in each sub circuit which process the least-significant bits in said sub-circuit always receive a logic signal "1" on their "b" data input and always operate as an add cell. The remaining add/subtract cells of an m'" sub-circuit are controlled by the carry signal output of the add/subtract cell which processes the most-significant bit in the (k-1) th  sub-circuit. As a result of the foregoing steps, the root extraction circuit requires only add/subtract cells, so that a very regular lay-out pattern can be obtained when the circuit is integrated.

Abstract: A method of measuring impedances, particularly low capacitances, in which method such measuring electronics is used which comprises one or more reference impedances, whose electrical ratings fall upon the measuring range. These refrence impedances are connected to a measuring circuit alternately with the impedance or impedances to be measured by a switch arrangement. 
     In order to take into account the individual non-linearities of the impedance sensor(s) (C e ) and possibly to compensate variations of ambient circumstances such as temperature, the measuring circuit is equipped with a memory (10) for storing the individual characteristic curve(s) y e =  f(x) of the sensor(s) and possibly the date arequired for the compensation. 
     The input signal (D,n) of said memory (10) are the binary sensor signals (An X 1 ,S 2 ..C n ) which define the memory addresses of said memory (10), and, the output signal (D out ) of said memory (10) are the values of the charasteric curve function f(x,,) corresponding to each sensor signal (X n ), said values containing the information about the quantity being measured. 
     The impedance sensor is used for measuring a changing physical quantity such as temperature, pressure, humidity, displacement, force and/or various types of radiation.

Filed: 1985-09-10
Abstract: A combinatorial circuit component for television sets with an overload protection circuit on the primary side and a secondary-side regulating circuit and starting circuit with final disconnection of the mains section. The protective circuit, which comes into play in the event of anomalies on the primary side, causes a jump in the negative voltage on the secondary side. This is compared with a secondary (standby) voltage, created independently of the combinatorial circuit, in a comparator, which supplies a control voltage to which the secondary protection circuit responds thus interrupting the excitation of the switch in the mains section.

Abstract: An explosively operated, confined linear explosive separation joint. The joint features a one-piece female member (12) of a clevis type shape with shear lip grooves (23) located on the outside surface of the clevis generally aligned with the fillet formed between the sidewall and the bottom of the opening in the clevis. The explosive means (22) is contained in the bottom of the clevis portion with the male portion (11) of the joint slidably nested in the clevis opening abutting the explosive. Shear lip groove alignment with the corner radius or fillet formed at the bottom of the clevis and the stiffer structure adjacent the breakpoint combine to ensure optimum use of the explosive energy and produce a joint which fails primarily in shear rather than tension, taking advantage of the material's weakest property.

Abstract: In a start controlling circuit for delivering a start signal to a constant current generator connected to a load (23), a reference voltage producing circuit (60) produces a d.c. reference voltage gradually rising from zero to a predetermined voltage. Supplied with an output voltage from a current detector (36) for detecting a load current which flows through the load, an error amplifier (61) amplifies an error between the d.c. reference voltage and the output voltage to deliver an amplified voltage to a converting circuit (45) and to a processing circuit (55). The converting circuit converts the amplified voltage into a first pulse sequence of a pulse repetition period which decreases in response to a rise of the amplified voltage. The processing circuit processes the first pulse sequence into a second pulse sequence of a pulse width which increases in response to the rise. The second pulse sequence is supplied to the generator as the start signal.
