Abstract: A vacuum brush nozzle for a vacuum cleaning apparatus, in which a height-adjustable, cylinder-type brush is mounted in a rotary manner, which brush is driven by a drive assembly via a belt drive. The drive assembly consists of an air turbine which is driven by the intake airflow which flows through the vacuum brush nozzle. This air-driven drive assembly can be exchanged by a drive assembly which is driven by an electric motor. For this purpose, fastening screws merely have to be unscrewed without further conversion work, since the electric mains connection lead is also mounted on the drive assembly driven by electric motor. It is likewise not necessary to exchange the belt drive when exchanging the drive assemblies. <IMAGE>

Abstract: An electric power circuit-breaker has a number of double contact points (13, 14) corresponding to the number of phases to be switched off, which double contact points each have two fixed contact pieces (15, 16) and each have a contact bridge (19) bridging the two, arc quenching devices (37, 38) being associated with each contact point. Each contact bridge is assigned an impact-type armature system which acts on in each case one contact bridge for opening the contact points, and in addition the circuit-breaker has a breaker mechanism (56) for the permanent opening of all contact points, on which the impact-type armature system and a thermal trip (58) act. The centre axis of the submerging armature of each impact-type armature system is flush with the centre axis of the contact bridge (19) and transmits its linear movement to the contact bridge (19) via an intermediate member (48) likewise executing a linear movement. The breaker mechanism (56) is arranged at the top front wall above the impact-type armature system (31) opposite the fastening wall (32) of the switch, and there is provided for each contact point a pivotable lever (50), the free end of which acts on the intermediate member (48) and on which a pin (53) acts for switching off, which pin is actuated by the breaker mechanism and extends parallel to the submerging armature. The circuit-breaker is employed for protecting electrical lines leading to motors and other equipment. <IMAGE>

Abstract: The cleaning device for the piping system (3) of a whirlpool bath (1), which piping system contains a circulation pump (2), comprises at least one suction opening (5) provided in the bath wall (6) and, likewise formed in the bath wall, output valves (8) connected to a pressure line and in each case having a nozzle for the supply of a water/air mixture to the inside of the bath. The latter is in communication with a discharge line (11) via a closable discharge opening (9) in the bath bottom (10). Each outlet valve (8) has a valve housing (22), an approximately cylindrical nozzle body (25) which delimits the nozzle channel (24) and is mounted in the valve housing by way of an external thread (40) and can thus be axially displaced by means of torsion, and an air-supply channel (23) which opens into an annular chamber (27) directly adjoining the input side of the nozzle body (25). A central nozzle core (26) is also provided which, when it bears on a valve seat (34) allocated to it, closes the valve and which, by relative axial displacement in relation to the seat, to a greater or lesser extent frees the outlet cross-section for the water/air mixture. A particularly effective and reliable cleaning is ensured in a simple manner by virtue of the fact that the nozzle core (26) is connected to a membrane (31) controlling it; this membrane is constantly acted upon in the direction of closure and delimits a first valve housing space (36) situated on the side remote from the nozzle core (26), which valve housing space (36) is connected to the pressure line (7, 28) by a first solenoid valve (13) or the like determining the duration of the closure state of the outlet valve (8). Disinfectant can be supplied to the suction line (4) by way of a metering valve (16). Provided between the pressure line (7) passing over all the outlet valves (8) and the discharge line (11) is a run-off line (16) with an interposed second solenoid valve (17) or the like, whose opening time is longer than that of the metering valve (16). <IMAGE>

Abstract: Methods of preparing storage stable components useful for metathesis bulk polymerization of cycloolefin monomers are provided. These components contain cycloolefins with norbornene-functional groups and cocatalysts activated with a halometal compound. In these methods, the cocatalyst is completely formed before the halometal activator is added to prevent the formation of unwanted hydrogen halides, which catalyze undesired crosslinking reactions which destabilize the cocatalyst component. Bulk polymerization systems are provided wherein these storage stable cocatalyst components are paired with catalyst components that together form the complete metathesis catalyst system. For some embodiments, storage stability is aided by the removal of water.

Abstract: A method and apparatus to improve the performance of an ultrasonic imaging sensor [11] is disclosed. The key to the performance improvement obtained in the present invention is in the matching of sensor element [10] size to the electrical characteristics of the train of pulses [24,32] used to drive the sensor. The matching causes essentially all the energy provided to the sensor [11] to go into the desired sensor resonances, those in the direction of the sensor's thickness dimension [12]. The matching also minimizes the energy which goes into the undesired dilatational resonance modes [16,18] those in the sensor element's width dimension [14]. The invention discloses the matching of each sensor element [10] so that its maximum dilatational response [54] is essentially at the same frequency as every other element in the array, so that dilatational response is substantially reduced for the array as a whole. The invention also discloses the "fine tuning" of the frequency of the drive pulses, so that the dilatational response is further reduced. The invention therefore permits the fabrication of ultrasonic sensor arrays [11], having high sensitivity, freedom from spurious returns, and low noise signals.
