Abstract: Bei Zeitmultiplexkoppelfeldern, die aus jeweils die zeitliche und räumliche Zuordnung von auf den angeschlossenen Zeitmultiplexleitungen bewirkenden Vermittlungseinheiten VE gebildet sind, bei denen ferner eine Unterteilung in wenigstens zwei einstufige Koppelfeldteile vorliegt und bei denen gleichgeordnete Eingänge und gleichgeordnete Ausgänge der Vermittlungseinheiten der einzelnen Koppelfeldteile miteinander verbunden sind, wordurch die Vermittlungseinheiten der einzelnen Koppelfeldteile sich bei einem Ausfall vertreten können, kann es trotz Verwendung sogenannter tristate-Ausgänge dazu kommen, daß in der Einschaltphase zwei miteinander verbundene Ausgänge gleichzeitig den aktiven Zustand annehmen, wodurch es zu einer Zerstörung der die Ausgänge bildenden Bauelemente kommen kann. Ferner kann die Aussendung von Freikanalcodeworten gestört sein. Um solche Fehler zu vermeiden sind erfindungsgemäß mit den Vermittlungseinheiten VE baugleiche, jedoch als Multiplexer betriebene Baueinheiten Mux vorgesehen, die mit einem Teil ihrer Ausgänge die Koppelfeldausgänge bilden und mit einem anderen Teil ihrer Ausgänge über normalerweise geöffnete Schalter S mit Ausgängen von zu anderen Koppelfeldteilen gehörenden Multiplexern verbunden sind, die Koppelfeldausgänge bilden. Lediglich wenn aufgrund eines Ausfalls der betreffende Koppelfeldteil für die Übernahme des normalerweise über den ausgefallenen Koppelfeldteil abgewickelten Verkehrs mit ausgenutzt wird, sind die genannten Schalter S geschlossen.

Abstract: A first transducer 7, having a centre frequency f' 2 , has a frequency characteristic for transmission T2' and a frequency characteristic for reception R2'.A second transducer 8, ha v ing a centre frequency f 1 , has a frequency characteristic for transmission T1, and a frequency characteristic for reception R1. T1 partly overlaps with R2'. Therefore, the first transducer 7 could receive reflected signals caused by ultrasonic transmission from the second transducer 8.To eliminate this crosstalk an electrical filter having a frequency characteristic LF (Figure 6) is provided, for example, on the receiving side of the first transducer 7. 
     Thus, the frequency characteristics of the transducers 7 and 8 have an inherent filtering function, and this is combined with the filtering function of an electrical filter provided for example on the receiving side of the first transducer 7. Electrical filters may be provided on the receiving side of the second transducer, or on the transmission sides of the first and second transducers.

Abstract: An arrangement to provide variation of the speed or other operating parameters of an electrical machine without connection to the rotor. The machine is of the induction type having a winding in separate parts to create a flux movable in the air-gap different speeds by the alteration of current in a part of the winding. In one example the current is altered by a variable impedance connected to one winding part, the other part being connected to an electrical supply. 
     Another example, Figure 6, shows two machines (NM 1 , NM 2 ) arranged to drive a rail vehicle through smooth rail wheels attached to the machine rotor axles. A single, variable-frequency, inverter (NI) drives both machines and is connected to part (MP) of each machine winding. Other parts (AP) of each machine winding are connected together by a link (NC). In operation power (real or reactive) is transferred between the machines along the link to equalize the torque of the machines. Run-away of one machine while the other stalls is thereby avoided.

Abstract: A beverage extracting and dispensing machine for use with flattened round cartridges which contain a brewable product, such as ground coffee, freeze-dried coffee, tea, broth and the like. The cartridges have permeable upper and lower walls and a substantially cylindrical sidewall. 
     A cartridge (C) may be slid to a brewing station (102) in which it is laterally embraced by opposite clamping jaws (114). During its movement to the brewing station (102), a new cartridge spreads the jaws apart and pushes an old cartridge away from the brewing station. The spreading apart of the jaws (114) starts an automatic brewing cycle at the beginning of which a presser plate (78) is lowered onto the cartridge and presses it with a tight seal on an underlying fixed support (94) while the cartridge is laterally clamped by the jaws. Then a predetermined amount of hot water under pressure is flowed into the cartridge from a passage in the presser plate (78) and the beverage is dispensed from the cartridge through a passage in the support to fill an underlying cup (T) or similar container.

Abstract: Systeme de commande de transfert de chaleur-energie entre une unite centrale et une structure comprenant plusieurs espaces. Le transfert chaleur-energie s'effectue en utilisant une ou plusieurs vannes de chaleur (10) disposees dans chaque espace pour commander independamment la vitesse a laquelle le transfert d'energie s'effectue entre cet espace et l'unite centrale (1). Les vannes de chaleur sont commandees pour assurer une utilisation maximum du temps (ton) de l'unite centrale tout en satisfaisant les besoins en temperature de la piece ou de la zone: par consequent, en fonctionnement normal, moins de toutes les vannes de chaleur (10) sont activees, le nombre de ces vannes en fonctionnement correspondant a la capacite de l'unite centrale. L'utilisation maximum du temps ton de l'unite centrale s'effectue parce que l'utilisation des vannes de chaleur (10) permet de regler la vitesse d'allumage du bruleur central par la charge thermique de la structure. Avantageusement, cette vitesse d'allumage peut varier et elle est reglee par le meme dispositif que celui qui commande les vannes de chaleur.

Abstract: A valve assembly for a container for pressurized fluid comprises a cup (10) for mounting the assembly to a container body, and valve means (14) including a valve housing (12) fitted in the cup. The valve housing is located within the cup by the engagement of internal projections (16) In the cup behind a head (18) of the housing. The cup, the valve housing and the valve means are arranged in one condition of the valve assembly to allow fluid to be passed into the cup and between an exterior wall of the housing and the side wall of the cup for filling the container. The exterior watt of the housing is provided with a multiplicity of narrow grooves (26) which define flow paths (62) for the passage of such fluid and these grooves are narrow in relation to the width of the internal projections, so that they do not impair the locating function of the projections. The grooves extend Into a collar (20) on the housing adjacent to the head, and because of their narrowness they provide extra flow paths past the projections which contact this collar, which paths cannot be blocked by the projections irrespective of the orientation of the housing relative to the cup.

Abstract: The invention relates to percussive drills for earth boring, and particularly to so-called valveless drills. In such drills it is important to allow, cyclically, compressed air to pass into the bore hole to clear debris through a central hole in the bit which central hole needs to be closed to allow the return stroke of the piston. This has been provided for hitherto by a short tube usually of plastics material, secured to the innermost end of the bit so that as the piston approaches the bit on the drive stroke the tube engages in a counterbore in the piston to seal the bore through the bit. Such short tubes are frequently damaged causing cessation of operation of the drill whilst down the hole, a circumstance that is to be avoided. The objective of the invention is to avoid the above disadvantage, which objective is met by a construction comprising an outer wear tube (1), compressed air inlet means (2) to one end of the wear tube, chuck means (3) for holding a drill bit (4) to the opposite end of the wear tube, a cylinder (5) located within the wear tube with an annular gap therebetween, an air diverter (6) located at the end of the cylinder towards the air inlet, a sealing bearing (7) located at theend of the cylinder towards the chuck, and a piston (10) within the cylinder, said piston having a portion (15) of reduced diameter adapted to pass through the sealing bearing to strike a bit held in the chuck, and there being porting (8, 9) to direct air to one side or the other of the piston to provide a drive and a return stroke.

Abstract: The field timebase circuit of a CRT includes a staircase generator for producing a stepped current waveform. The generator is synchronised with the horizontal synchronisation pulse, the vertical deflection field stepping only in response to the stepped waveform. The vertical or field synchronisation pulse is used to reset the staircase generator. In practice a capacitor 31 is periodically charged in synchronisation with the horizontal flyback pulse by means of a charge generator 30. A buffer amplifier 32 and power amplifier 33 connected to the capacitor 31 provide the vertical or field deflection current. Reset circuit 36 responsive to the vertical or field synchronisation pulse periodically discharges the capacitor 31 to a base value.
