Title: Large scale array driver circuit for bipolar devices
Inventor: HAYES DONALD EUGENE
IPC: H03K19/096
Filed: 1970-10-28
Abstract: 1278175 Transistor switching circuits NORTH AMERICAN ROCKWELL CORP 28 Oct 1970 [22 Dec 1969] 51292/70 Heading H3T An output terminal 2 is connected to one supply V1 or the other V2 by F.E.T.'s 17, 21 controlled by an input V IN  through respective channels each having clocked gates, such as gating F.E.T. 12 controlled by # k , and gating F.E.T. 22 controlled by # i+j , F.E.T. 17 is turned on by a negative voltage V which charges C18 via F.E.T.'s 8, 12 in # k  time, provided V IN  is not negative as this would turn on F.E.T. 4 and discharge C18 in # k  time. This non- negative V IN  passes through F.E.T 22 in #i+j time but does not turn on F.E.T. 24, so F.E.T. 21 is off. When V IN  is negative, C18 discharges in # k  time to turn off F.E.T. 17 ; and a capacitor C28 is charged in # i+j  time by the negative V IN  passing through F.E.T. 22 to one plate of C28 while its other plate is held at the then earth level of # k  by F.E.T. 24 which is now turned on by V IN . When # i+j  ends, and # k  goes negative, F.E.T. 22 goes off but the negative # k  passes through F.E.T. 24 held on by the charge on C28, and is fed back through C28 to enhance conduction of F.E.T. 24. The negative charge thus accumulated on C33 turns on F.E.T. 21 to connect the output 2 to V2. The output 2 drives bipolar transistor circuitry.

On the shovel-carrying arm of a shovel excavator is so arranged a projection, that when the shovel is operating at a desired depth, the projection interrupts a collimated beam of electromagnetic radiation directed parallel to the desired depth level to cause a signalling means to provide a signal that the beam has been interrupted. The beam may be a collimated beam of light or a short wave radio beam. When a light beam is used'it is directed at a light responsive means controlling the signalling means, which may involve a radio link between, the light responsive and the cab of the excavator, to give a visual signal in the cab.

Cleaning apparatus for removing droppings from a battery system comprises a scraper 17 arranged to travel in stages along a collecting tray 12-14 below cages 11, returning after each stage to a discharge end 19 to remove droppings accumulated on the portion of the tray last traversed, the scraper 17 travelling forwards and backwards until the whole of the tray has been cleared. In a three tier battery, Fig. 2, each scraper 17 is carried by a chassis 37, Fig. 3, slidable on channel section members 15 of a main frame 10, and discharges the droppings onto a conveyer 21. A respective draw bar 41 is slidably mounted on the chassis 37 and is secured at each end to a common driven cable 18. The scraper 17 is pivoted on a pin 44 attached to the bar 41 and is further pivoted to links 45 pivoted to the chassis 37. On actuating the cable 18 away from the discharge end 19, the scraper 17 is pivoted to an essentially horizontal position, whereupon the chassis 37 is pulled outwardly, and on reversing the cable 18 the blade 17 resumes its operative position, the links 45 engage stops 46, and the scraping operation is performed. The common cable 18 is operated by a reversible electric motor 35, controlled automatically after initiation of the process by a sequence controller (47), Fig. 1 (not shown), and an electronic timing device (48), incorporating a distance control (49) for pre-setting the length of each scraping stage. Alternatively a portable power unit may operate the cleaning apparatus of several battery systems in turn, and the scraper drive may be utilised to operate a feed dispensing system.

In an analogue to digital converter of the type in which the input voltage V 1  (Fig. 1) and a reference voltage-V R  (V R >V I ) causes the output of operational amplifier 12 to ramp up to a level V D  detected by a detector 17 (during which time clock pulses are counted in a counter 31) the reference signal then being removed to allow the output to ramp down, this process being repeated, during one measurement a switch controlling the reference signal is enabled at the beginning of the cycle and then after decreasing time intervals (Fig. 2, not shown). This is effected by resetting bi-stables 16 at the start of the cycle to enable gate 33 to connect the counter 31 to clock source 19 and to enable FET switch 14. The bi-stable is set when the detector 17 detects the level V D  and then reset by the output of auxiliary counter 21 on lead L1 at a count of 1000000 (that is after 10 ms.) the amplifier output then again ramps up until the level detector sets the bistable 16 which is again reset by the output signal on lead L2 after a further 5 ms. The process is repeated with the bi-stable being reset after further intervals of 2À5 ms., 1À25 ms. &c. until a signal on lead L3 representing the resetting of counter 21 to zero causes readout of the counter 21 to a staticizer 32.

The longer exposure time uses the full light emission of a flash-bulb whilst the short exposure time uses only a part thereof. The shutter consists of a single pivotted blade 2 driven by an arm 6 to uncover an exposure aperture 5. The short exposure time is obtained by stopping the blade in the dotted line position by either members 8, 16, otherwise the longer exposure time is obtained by allowing the shutter blade to swing freely against its spring 3.

As shown, the wheel 1 carries the seconds drum of a digital clock and a cam 2 with a recess 3. The switch B is normally held closed by the cam 2 but once a minute rider 9 drops into the recess 3 allowing the switch to open. This normally has no effect since the switch A is closed, but if knob 11 is pushed in, an insulating nose 16 opens the switch A so that switch B stops the wheel 1 at zero seconds.
