    • The invention relates to a ladder that includes a support device. A mounting plate is securely fixed to an outer surface of a side rail of a ladder, which is adjacent to one end of the ladder. A removable wheel assembly has a frame that is removably supported on mating interfitting parts between the wheel assembly and the support member or plate. The support member includes a bracket member and a rotatable device, such as a wheel, that is housed in the bracket member. The bracket member includes a U-shaped section for retaining the wheel member, and an elongated section for attachment to the ladder. The device is used for easily moving the ladder from one place to another. The interchange from one ladder to another is simply by unbuckling it from one ladder, pulling it off, sliding it on the new ladder, and buckling it back on. The ladder wheel should be placed between the top of the ladder and the first step from the top of the ladder.

    • A continuous inkjet recording apparatus forms a continuous stream of droplets from a jetted fluid. A charge electrode is employed to characterize droplets selected for printing from droplets that are not selected for printing. The charge electrode is sized and optionally positioned such that a specific droplet scheme can be employed to minimize droplet trajectory variations from droplet-to-droplet electrostatic field effects. Additionally, the charging surface is sized and positioned to minimize droplet trajectory variations that arise from charge electrode-to-droplet electrostatic field effects. By minimizing both these sources of droplet trajectory variation, the final print quality of the continuous inkjet apparatus is improved.
    • 连续喷墨记录装置从喷射流体形成连续的液滴流。 使用充电电极来表征从未被选择用于印刷的液滴中选择用于印刷的液滴。 充电电极的尺寸和任选地定位成使得可以使用特定的液滴方案来使从液滴到液滴静电场效应的液滴轨迹变化最小化。 此外,充电表面的尺寸和位置被设置为使由电荷到液滴静电场效应产生的液滴轨迹变化最小化。 通过最小化液滴轨迹变化的这两个来源,连续喷墨设备的最终打印质量得到改善。

    • An apparatus for controlling droplets allows the phase difference between a calibration signal and its signature signal on a detector to be minimized, or the amplitude of the signature signal to be maximized, by adjusting the droplet charging means of the device, or the droplet generation means, and the signals on either. The apparatus converts a stream of fluid into a stream of droplets under the influence of a droplet stimulation signal imposed onto the droplet generating means. Droplets are subsequently signal-wise charged under the influence of a droplet charging signal imposed on the droplet charging means. The charged droplets are then deflected. The calibration signal is imposed onto the stream of droplets. The calibration signal has characteristics that do not appreciably affect the trajectory of the stream of droplets, thereby ensuring that the placement accuracy of the individual droplets is a maintained. The calibration signal further has a signal phase that is independent of the droplet charging signal. A charge detection means is used to extract a charge detection signal from the at least a part of the droplets. The charge detection signal is filtered to extract a signature signal of the calibration signal. The phase control system then varies at least one of the droplet generation means, droplet stimulation signal, droplet charging means and droplet charging signal until the phase between the signature signal and the calibration signal is minimized. A plurality of streams of droplets may be controlled by the method of the invention.
    • 用于控制液滴的装置允许通过调节装置的液滴充电装置或液滴产生装置将校准信号与检测器上的签名信号之间的相位差最小化,或者使签名信号的振幅最大化 ,以及两者之间的信号。 该装置在施加到液滴产生装置上的液滴刺激信号的影响下将流体流转换成液滴流。 随后,在施加在液滴充电装置上的液滴充电信号的影响下,液滴被信号地充电。 带电的液滴然后被偏转。 校准信号被施加到液滴流上。 校准信号具有不明显地影响液滴流的轨迹的特性,从而确保单个液滴的放置精度得到维持。 校准信号还具有独立于液滴充电信号的信号相位。 电荷检测装置用于从液滴的至少一部分提取电荷检测信号。 对电荷检测信号进行滤波以提取校准信号的签名信号。 相位控制系统然后改变液滴产生装置,液滴刺激信号,液滴充电装置和液滴充电信号中的至少一个,直到签名信号和校准信号之间的相位最小化。 可以通过本发明的方法来控制多个液滴流。
