Title: Monitoring device for drive amplifiers
Inventor: NILSSON KURT ALLAN INGVAR
IPC: H03F3/347
Filed: 1984-03-30
Abstract: A monitoring device in an integrated drive amplifier intended to be driven by digital signals includes fault detection circuits (17, 18, 19, 20) giving a fault signal for such as excess temperature; overcurrent; and interruption or short-circuiting in the load circuit. The input of the drive amplifier is connected to the output of a D-type flip-flop (13) having a data input (D) and a control input (C) intended for connection to a digital control system. Between the data input and a potential corresponding to a logical "zero" there is connected a circuit (22, 23) adapted for connecting the data input to said potential during the interval between the operation signals when a fault signal is present, the resulting current sink (23) sinking current from the control system output terminal (I/O), thereby signalling the existance of a fault condition to the control system. <IMAGE>

IPC: B25B13/46
Filed: 1984-05-21
Abstract: A spanner comprises a stem 12 having a jaw 14 at one end, which jaw has a pair of opposite sides providing a pair of substantially parallel inner faces for engaging with a nut, bolt, coupling, or the like. The jaw is capable of limited pivotal movement relative to the stem about a first axis 20 which is substantially perpendicular to the plane of the spanner and the one side of the jaw 14.1 is capable of pivotal movement relative to the rest of the jaw about a second axis 16 which is substantially parallel to the first axis 20. The first axis is off-set with respect to an imaginary centre line which is parallel to and equidistant from the pair of opposite inner engaging faces of the jaw. The first and second axes are on opposite sides of the centre line. The spanner further includes a projection 24 on the stem which is adapted to engage with the jaw to counteract relative pivotal movement of the one side of the jaw with respect to the rest of the jaw and to counteract the pivotal movement of the jaw with respect to the stem when the jaw, when engaged with a nut or bolt is turned in one direction and adapted to disengage with the jaw when the spanner is turned in the opposite direction. <IMAGE>

Title: Method and apparatus for making alloy powder
Inventor: JACKSON JOSEPH JAY
IPC: B22F9/08
Filed: 1984-05-22
Abstract: The alloy powder is made using apparatus comprising, in combination, a fluid-cooled hearth 12 for receiving metallic material which defines an alloy and which is to be melted, a plasma heat source 20 adapted to melt the metallic material, a powder metal producer 46, and means to introduce the molten metallic material from the hearth into the powder metal producer. The fluid-cooled walls of the hearth resolidify a portion of the molten metallic material to form a skull as a barrier between the hearth and additional molten alloy produced within the hearth. This method and apparatus restricts introduction of impurities into the molten alloy which is later introduced into the powder metal producer. In one form, a fluid- cooled pouring trough 34, as a stream control device, can be disposed between the hearth and the powder producer to receive molten metal from the hearth and to introduce it into the powder metal producer. <IMAGE>
Patent GB-2164528-A (GB)
Title: Wideband transmission system
Inventor: DYKE PETER JOHN
IPC: H04H20/79
Filed: 1984-09-14
Abstract: In a cable TV system each "compulsory" stereo radio channel CH1 etc left and right information is digitally encoded and transmitted as TDM baseband signals via primary and secondary links to a subscriber who selects a desired channel from the appropriate time slot. The arrangement removes the need for a timer at the subscriber unit and also enables a longer, narrower band secondary link to be used, resulting in fewer local switch points. <IMAGE>
