摘要： A hand vacuum cleaner is provided comprising a lightweight motor housing containing a revolving brush. A bag assembly is selectively separable from the housing and is sealable to the housing with an elastomeric retaining ring including a sealing and retaining bead for reception in a recessed slot area of a housing bag attachment collar. A fan is mounted to the motor on a motor shaft locking surface including a wall portion tapering towards the fan. The shaft is in locking cooperation with a mating fan bore locking surface including a wall portion tapered for close reception of the motor shaft locking surface. A shaft extension is threadedly received on the motor shaft and is urged into engagement against the fan by resistance of a revolving brush operated by a belt received on the shaft extension which continually tightens the shaft extension to the motor shaft and fixes the fan to the motor shaft. A stone shield is circumferentially spaced about the fan whereby the stone shield blocks items impinging against the housing from the fan from damaging the housing. The housing further includes an air deflector substantially received in the bag assembly having a terminal end portion disposed radially inwardly from the housing outer wall whereby the deflector directs the working air to facilitate greater storage of vacuumed dirt in the bag and prevent heavy objects received in the bag from rolling back into the housing and contacting the fan.

摘要： A disco light assembly is provided which includes a multiplicity of individual electric lamps formed in a circle, or in any other appropriate configuration, and which are illuminated in any desired sequence in response to a disco beat. The individual lamps are preferably of the high intensity type, and each generates a shaft of light, preferably white, when illuminated. A common regulated power supply is provided which supplies a continuous filament current to all the lamps which is of sufficient amplitude to maintain the filaments in a warm state but insufficient to illuminate the lamps. Each lamp has its own control module connected to the common power supply, and when a module is triggered, it causes a high current pulse to be introduced to the corresponding lamp for a few milliseconds, followed by a power current of sufficient intensity to illuminate the lamp. The power current continues for so long as the lamp is to be illuminated. A rapid turn-on circuit is included in each module, so that each lamp is quickly turned on without creating any undue thermal stress in the lamp filament. However, the lamps turn off at a relatively slow rate. This obviates irritating strobe light effects.

摘要： There is disclosed a digital loop for interconnecting a number of data interchangers, each data interchanger connectable over a single high speed communication link to a remote station controller. The high speed link is arranged to bidirectionally transfer both bursty and continuous data to and from the data interchanger. A central controller is serially inserted in the digital loop and serves to assign time slots in a frame for information exchange between the various programmable data interchangers. Each frame contains a first field for data interchange between the data interchangers and the central controller; a second field having time slots assignable under control of the controller to a specific set of data interchangers for transferring information from the continuous data inputs; and a third field having time slots assignable under control of each data interchanger for transferring information from the bursty data input. The controller in cooperation with the data interchangers varies the size of the fields of each frame such that the portion of the field associated with continuous communication expands and contracts as traffic flow changes thereby increasing or decreasing the number of time slots available for the transfer of bursty data.

摘要： This invention is directed to an improved method of forming and installing polytetrafluoroethylene (PTFE) lip seals and to a novel PTFE lip seal. The lip seals are formed by taking a flat, annular PTFE washer having given dimensions and stretching it over a tapered mandrel by pushing it toward the direction from which the fluid pressure will come in the sealing operation. The finished PTFE lip seals have a curved configuration. Both O.D. and I.D. lip seals are disclosed.
