摘要： The invention is a mounting arrangement for mounting a flange mounted electric motor (M) of the type including a motor housing (15) and a mounting flange (17) fixed to the housing and formed with a first bearing surface (18), at least two flange mounting ears (19), and mounting openings (20) formed in the flange mounting ears. In accordance with the invention the mounting arrangement comprises a supporting frame (17) for supporting the electric motor (M), a second bearing surface (23) on the supporting frame (12) adapted to mate with the first bearing surface (18) on the mounting flange (17), and at least two motor support members (24) on the supporting frame (12) adapted to cooperate with the flange mounting ears (19).
The invention is characterised in that the bearing surfaces (18, 23) are both cylindrical and in that each motor support member (24) includes an inner portion (25) attached to the supporting frame (12), a resilient outer portion (26) extending from the inner portion (25) and in spaced apart relationship with the support frame (12), and a cam projection (30) extending from the outer portion (26) towards the supporting frame (12) so that its outer surface (30a) is normally spaced from the supporting frame (12) by a distance less than the width of each of the flange mounting ears (19).
In order to mount the motor (M) the mounting flange (17) is placed on the supporting frame (12) so that the cylindrical bearing surfaces (18. 23) mate and the mounting flange (17) is then rotated to that each of the flange mounting ears (19) engages with a respective motor support member (24) with each flange mounting ear (19) being located in the space between the outer portion (26) of its associated motor support member (24) and the support frame (12). Further rotation of the mounting flange (17) causes each flange mounting ear (19) to engage with the cam projection (30) of the associated motor support member (24) to cause deflection of the associated outer portion (26), and still further rotation of the mounting flange (17) causes each cam projection (30) to become positioned in the mounting hole (20) of the associated flange mounting ear (19) so as to secure the motor (M) in position mounted on the supporting frame (12).摘要翻译： 本发明是一种用于安装凸缘安装式电动机（M）的安装装置，其包括固定在壳体上的马达壳体（15）和安装凸缘（17），至少形成有第一支承表面（18） 两个法兰安装耳（19）和形成在法兰安装耳中的安装开口（20）。 根据本发明，安装装置包括用于支撑电动机（M）的支撑框架（17），支撑框架（12）上的适于与第一支承表面（18）配合的第二支承表面（23） 安装凸缘（17）和支撑框架（12）上的至少两个电动机支撑构件（24），其适于与凸缘安装耳（19）配合。 本发明的特征在于，支承表面（18,23）都是圆柱形的，并且每个马达支撑构件（24）包括附接到支撑框架（12）的内部部分（25），弹性 从所述内部部分（25）延伸并且与所述支撑框架（12）间隔开的关系的外部部分（26）以及从所述外部部分（26）朝向所述支撑框架（12）延伸的凸轮突起（30），使得 其外表面（30a）通常与支撑框架（12）间隔小于每个凸缘安装耳（19）的宽度的距离。 ...为了安装电动机（M），将安装法兰（17）放置在支撑框架（12）上，使得圆柱形支承表面（18,23）配合，然后安装法兰（17） 旋转到每个凸缘安装耳（19）与相应的电动机支撑构件（24）接合，每个凸缘安装耳（19）位于其相关联的电动机支撑构件（24）的外部部分（26）之间的空间中 ）和支撑框架（12）。 安装凸缘（17）的进一步旋转使得每个凸缘安装耳（19）与相关联的马达支撑构件（24）的凸轮突起（30）接合以引起相关联的外部部分（26）的偏转，并且还进一步 安装凸缘（17）的旋转使得每个凸轮突起（30）被定位在相关联的凸缘安装耳（19）的安装孔（20）中，以将电动机（M）固定在安装在支撑框架 （12）。

摘要： An analog video data signal digitisation and correction system scans a medium to produce video data signals (21, 13a) representing images printed on the medium. Two reference quantities (31, 32) representing analog reference signals produced by scanning a densely printed image and an area of the medium having no printed image are used to establish the maximum and minimum values of a range of possible values for each video data signal. The analog video data signals are compared (24) with this range and a corrected digital value obtained for each data signal depending on its position in the range. In generating the reference quantities each analog reference signal is converted into a digital reference signal dependent on the position of the analog signal in a range of possible values. For each analog reference signal only a portion of the range of possible values is selected in order to increase the accuracy of the corresponding digital reference signal. The number of bits in the digital reference signal is kept low but the accuracy of each digital reference signal remains high. In converting each digital reference signal into an analog reference quantity additional high order bits are added to the digital reference signal so that each analog reference quantity has the same accuracy as its corresponding digital reference signal.

摘要： An object manipulator includes a gripper (15) formed with at least two fingers (24, 25) which are mounted for relative movement so as to be able to grip an object to be manipulated. At least one tool (32) is mounted on a respective one of the fingers and is adapted to engage with the object. The manipulator also includes control means (16) for controlling the relative movement of the fingers.
The tool and its associated finger are formed with cooperating surfaces (36, 37) which allow the tool to be moved in two opposite directions on and off the finger but prevent relative movement between the tool and the finger in any other direction. The cooperating surfaces also cause a frictional force to be exerted on the tool when the finger is gripping an object and this force resists any relative movement between the tool and the finger in the two opposite directions.
The tool and its associated finger are also formed with yieldable means (43,44,45) for retaining the tool in position on the finger.摘要翻译： 物体操纵器包括形成有至少两个指状物（24,25）的夹持器（15），所述指状物被安装用于相对运动，以便能够夹持待操作的物体。 至少一个工具（32）安装在相应的一个手指上并适于与物体接合。 操纵器还包括用于控制手指相对运动的控制装置（16）。 该工具及其相关联的手指形成有配合表面（36,37），其允许工具在手指上和下方两个相反的方向上移动，但是防止在任何其它的工具和手指之间的相对运动 方向。 当手指握住物体时，配合表面还引起摩擦力施加在工具上，并且该力抵抗在两个相反方向上的工具和手指之间的任何相对移动。 工具及其相关联的手指也形成有用于将工具保持在手指上的适当位置的可屈曲装置（43,44,45）。

摘要： An ink jet drop-on-demand printing system having grey scale capability comprising a transducer having a plurality of separately actuable sections 16. Print data is provided which defines a selected drop volume and control means (14) is provided which is operable in response to the print data to produce drive signals to selectively actuate a particular combination of the separately actuable sections 16 of the transducer to produce a drop 15 of the volume specified by the print data. To provide further control over the drop volume while maintaining the drop velocity within selected limits, the amplitude of the drive signals can also be varied. A further refinement can be provided by varying not only the amplitude of the drive signals but also the pulse width of the drive signals. In the embodiment shown in the drawing the transducer sections are of equal length, while the sections are of unequal length in a second embodiment.
