    • There is provided a receiver equalizer comprising, a first equalizer unit having a basic equalizer stage and a negative impedance cell connected to said basic equalizer stage. Preferably the negative impedance cell comprises a pair of back to back transistors, and connected thereto a parallel resistor capacitor RC network. The basic equalizer stage comprises: a pair of current sources; a pair of transistors arranged as a differential pair, each transistor connected to a different one of the current sources; and a degeneration impedance connected in between the two current sources, and the transistors, wherein the negative impedance cell is connected across the outputs of the pair of transistors.

    • Control units at each support have means for receiving function initiating signals from a communication system common to the supports, means responsive to those function initiating signals for issuing corresponding control signals to component elements of the associated support and means for transmitting data to the communication systems. A remote control unit has means for issuing control signals including such function initiating signals over the communication system, means for receiving data from the supports, means for specifying a sequential or automatic mode wherein support advancing means are successively operated sequentially, and means for displaying data from and relating to the supports. Advantageously, the sequential or automatic mode specifying means is operative relative to a preset distance, and the remote control unit further comprises means for specifying selective or manual modes wherein an individual support is selected and controlled without reference to any set sequence, one such selective or manual mode implementing the operation of the support advancing means to a, or said preset distance, and another allowing such operation without preset of its distance.
    • 每个支持处的控制单元具有用于接收来自支持共同的通信系统的功能发起信号的装置,响应于那些功能启动信号的装置,用于向相关支持的组件元件发出相应的控制信号,以及用于向通信系统发送数据的装置。 遥控单元具有用于通过通信系统发出包括这种功能启动信号的控制信号的装置,用于从支架接收数据的装置,用于指定顺序或自动模式的装置,其中支持提前装置依次顺序地操作,以及用于显示数据的装置 来自和与支持有关。 有利地,顺序或自动模式指定装置相对于预设的距离是可操作的,并且遥控单元还包括用于指定选择性或手动模式的装置,其中选择和控制单独的支持而不参考任何设定的顺序,一个这样的选择性或 手动模式将支撑推进装置的操作实现为或所述预设距离,另一种允许这种操作而没有预设其距离。

    • A method of modifying morphology in a plant by introducing into a plant at least one chimaeric gene having a promoter sequence operably associated with a nucleic acid sequence, the promoter sequence being operable to direct expression in specific cells of the plant and the nucleic acid sequence encoding at least one gene product capable of altering the metabolism of or causing death of the specific cells and/or nearby cells. In particular, the promoter sequence is operable to direct expression in lateral bud or lateral shoot and the nucleic acid encoding at least one gene product capable of disrupting the metabolism of or causing the death of the lateral bud or lateral shoot or nearby cells. Preferably the promoter sequence has the sequence shown as SEQ ID No. 1 or SEQ ID No. 7 or SEQ ID No. 4, or a part thereof capable of regulating expression of a gene, or a sequence having at least 60%, preferably at least 75%, homology to SEQ ID No. I or SEQ ID No. 7 and being capable of regulating expression of a gene.
