Abstract: A high-pressure cleaner consisting of pump and drive motor, preferably electric motor, is combined with a hose truck. The installation of the electric motor and high-pressure pump and a centrifugal coupling connected between them occurs within the hose drum which consists of plastic and on which the low-pressure hose, the electric cable and, if appropriate, also the high-pressure hose can be wound in axially separate spaces. A combination hose can be used which carries the water in a channel and receives the electric cable in a different channel. In conjunction with the hose truck, a splash guard bell with extraction means can be used, inside which the high-pressure nozzle comes to rest, and which cleans facades, plates or other surfaces. A washing brush or washing roller which rotates around the longitudinal axis can be connected to the end of the high-pressure pipe in conjunction with a water turbine. <IMAGE>

Abstract: A vertical motion detector for a TV system motion detector. The circuit operates by delaying each motion indicator signal by multiple units (21) of the time required for one full horizontal line sweep. If vertical motion occurs, the delayed indicator will output from the delay at the same time another indicator occurs. These signals are fed to multiple AND gates (32) so that several coincident signals are required to produce an alarm. A switching circuit (36) permits selection of the number of vertical motion indicators required for an alarm.

Abstract: Image developing apparatus, for developing a latent electrostatic image, includes a container (12), for holding a supply of toner particles (D), and a developing roller (18) made of an electrically-conductive elastomeric material and supported for rotation in contact with toner particles in the container so as to entrain a layer of such particles and carry them to a location at which the roller engages a surface bearing such an image. A blade member (22) is pressed against the developing roller for regulating the thickness of the said layer, and respective bias voltages are applied to the developing roller and to the blade member for ensuring that the toner particles of the said layer are electrically charged in a desired manner and/or for preventing electrostatic adhesion of such particles to the blade member. 
     Danger of localised damage due to electrical current flow between the blade member and the developing roller, prior to attainment of its normal speed of rotation, is reduced by delaying application of the bias voltages for a preset period of time after initiation of the said rotation. 
     When such rotation is to be stopped, by termination of a drive signal (DS) maintaining that rotation, the application of the bias voltage to the blade member is terminated at a first instant. The drive signal is then terminated at a second instant, a predetermined short period of time after the said first instant, the application of the bias voltage to the developing roller being maintained until the said second instant, thereby to encourage separation of toner particles from the roller during that predetermined short period.

Abstract: The elastic properties of an optical fiber (10) are determined from measurements of the contact area (20, 24) of the optical fiber (10) against a surface (16, 22), under a loading perpendicular to the surface. In a preferred approach, an optical fiber is passed over a curved surface (22) of a transparent lens in the form of a pulley (38), with a tension applied to the optical fiber (10). The buffer layer (14) of the optical fiber (10) is flattened against the curved contact surface (22), forming a contact region (24) whose area is measurable. The relative elastic deformability of the buffer layer (14), a function of its elastic modulus, is determined from the contact area and other measurable parameters. Contact area measurement is performed continuously as the optical fiber (10) is passed over the pulley (38) by monitoring the amount of light that is transmitted through the contact region (24). The variations in the elastic properties of the optical fiber (10) may therefore be measured continuously as the optical fiber (10) is transported over the pulley (38).

Abstract: There are provided a position and velocity control system (1) for producing a velocity command signal in response to a position command signal and a signal representing a current position and velocity of a servo motor, a current control system (2) for supplying a drive current to the servo motor in response to the velocity command signal, and a communication system (13, 21) for transmitting data between the two systems (1, 2) by means of a bilateral communication line. A servo control system is thereby separated between the current control system (2) and the position and velocity control system (1) and connected to each other through the communication system (13, 21). This separation through the communication system is advantageous for protecting the position and velocity control system from influence of noise generated in the current control system and also brings about benefits such as expansion of the controllability owing to the bilateral communication, sharing of a single current control system by plural servo motors by switching connection of the servo motors and controllability of plural pairs of servo motor and current control system by a single position and velocity control system by a multi-point connection.

Abstract: In some analyzers, delays may occur in sequential dispensing of patient sample. These delays may be due to rate assays being carried out in the analyzer. This means that stations upstream from a rate assay point cannot offload any other test elements until the rate assay has been completed. As a result, delays are also caused at the dispensing station which causes exposed patient sample retained in the dispensing tip of the pipette to dry up plugging the tip. In addition, analyte concentration of the sample to be analyzed can be changed unacceptably due to evaporation at the tip. Described herein is an arrangement in which capping means (92, 94, 98, 101) are provided which cover the dispensing aperture of the pipette (82) when a test element (E) is not in position to receive a sample. The capping means (92, 94, 98, 101) comprise a cap portion (92, 101) which is mounted in a support (98) and is moved between a first covering position (shown in phantom) and a second uncovering position by an advancing test element (E).

Abstract: Liquid toner conditioning apparatus and method for use in an electrophotographic color printer and including a stabilizing roller (76) (Figure 3) positioned adjacent to the surface of a photoconductive drum (10) and operative for transforming discrete color toner particles on the surface of the drum (10) into a stabilized unitary polymeric film structure which may be directly transferred onto an adjacent print medium. Advantageously, the stabilizing roller (76) comprises a deformable roller member including a soft open cell conductive foam (78), such as a wettable polyurethane foam which is disposed on a biased slip ring (80). The bias slip ring (80) is in turn formed on the outer surface of a central motor driven metal roller core member (82), and a suitable DC bias connection (86, 88) is applied to the slip ring. The applied DC bias voltage (88) has the same polarity as the desired charge on the toner and of an opposite polarity to the counter ions within the isopar carrier fluid for transporting the toner on the surface of the photoconductive drum (10). Therefore, when the conductive deformable conditioning roller (76) is rotatably driven (48, 50) against the surface of the photoconductive drum (10), it provides three (3) critically important functions. First, it absorbs isopar fluid from the surface of the photoconductive drum (10) which reduces isopar carry out on the media (30). Secondly, it compresses the toner image electrostatically on the drum (10) to preserve its fidelity inasmuch as the polarity of the applied DC bias (88) repels the like charged toner ions into the surface of the photoconductive drum. Thirdly, the DC bias (88) applied to the slip ring (80) pulls counter ions in the isopar fluid from the surface of the drum (10) to thereby leave a desirable positive net charge on the toner as its proceeds to the print media (30).

Abstract: In the system according to the invention, the control elements of failsafe systems are activated by signals which are formed in at least two computer units or computer channels. Each computer unit or each computer channel is monitored by a monitoring device. Drives of the control elements of one of the computer units or computer channels are only activated if the monitoring device associated with the computer unit or with the computer channel detects error-free functioning of the computer unit or of the computer channel. According to the invention, each of the monitoring devices can place the failsafe systems in a secure state irrespective of the monitoring results of the further monitoring devices when an incorrect function of the associated computer unit to be monitored or of the associated computer channel to be monitored is detected. As a result, a high safety level of the failsafe systems is achieved since each monitoring device can transfer the system into a secure state. <IMAGE>

Abstract: The temperatures of LED print bars (40,50,60) utilized in a printing system are maintained within a specified differential range, with respect to each other. Each print bar has an associated heating (40A,50A,60A) and cooling (40C,50C,60C) element. The temperature of each print bar is monitored and compared during operation. When a temperature differential greater than a preset tolerance range is detected, either the hotter operating print bar is cooled or the lower operating print bar is heated, or a combination of cooling and heating is applied to the out-of-tolerance print bars. The cooling and/or heating of the print bars is continued until the temperature differential is reduced so as to be within the preselected or predefined range.
