Title: Improvements in or relating to monostable and astable circuits employing transistors
Inventor: NEWELL ALLEN FREDERICK
IPC: H03K4/52
Filed: 1960-12-15
Abstract: 935,657. Transistor pulse generating; monostable and astable circuits. MULLARD Ltd. Feb. 1, 1962 [Dec. 15, 1960; June 8, 1961], Nos. 43214/60 and 20753/61. Class 40 (6). A monostable circuit comprises a first transistor T 1  (Fig. 1 of Prov. Specification 43214/60) of an approximately unity having a diode D 1  connected between its emitter and earth and a resistor R 1  as collector circuit, a second transistor T 2  also of an approximately unity, and a regnerative feedback loop comprising a direct coupling between the collector of transistor T 1  and base of transistor T 2  and coupling by means of condenser C 2  between emitter of transistor T 2  and emitter of transistor T 1 . The emitter current of transistor T 2  is derived from a further transistor T 3  connected to form a constant-current generator. The coupling between T 1  and T 2  may alternatively be capacitive provided the time-constant is long. In the stable state transistor T 1  is cut-off and T 2  conductive. A negative-going trigger pulse applied to C 1  causes T 1  to conduct, producing a positivegoing step at its collector and the base of T 2 . T 2  is then cut-off and current flows from the source T 3  via condenser C 2  into the emitter of T 1  until the voltage across C 2  rises sufficiently to bring T 2  back into conduction. The current through T 1  then decreases, causing a negativegoing step at its collector and the base of T 2 . The action is cumulative, ending with T 1  cutoff and T 2  conducting. The diode D 1  enables the condenser C 2  to be recharged in a relatively short time. The arrangement produces lengthened rectangular pulses at the collector of T 1 , a saw-tooth wave with a step at the leading edge, at the emitter of T 2 , and delayed pulses at the emitter of T 1  and collector of T 2  (Fig. 2, not shown). To obtain a true saw-tooth wave at the emitter of T 2  a transistor T 4 , Fig. 3, of Prov. Specification 43214/60, of opposite conductivity type may be coupled between its collector and base, resistor Rb being adjusted so that the voltage fed back by this transistor into R 3  cancels the initial step. Diode D 2 . prevents breakthrough of the positive-going edges of the trigger pulses. The arrangement may be made free-running by adding resistor Rd which provides forward bias for transistor T 1 , in which case Ra, Rb, Rc, T 4 , C 1  and D 2  are omitted. In a further modification of the first arrangement the collector-emitter path of a further transistor T 40 . Fig. 1 of Prov. Specification 20753/61, is connected in the lead between the emitter of transistor T 2  and the constantcurrent source S, its base being earthed and the diode D 1  returned to its emitter. Resistor R 3  is returned to the top of a potentiometer connected between earth and the positive supply. The arrangement prevents overswing of the voltage and current of the collector of transistor T 2  which otherwise occurs immediately after a pulse. Specification 767,727 is referred to.

The wheels 2, 3 are steered during road travel by a steering wheel 10 which controls a power-assisted mechanical steering system comprising hydraulic power-assistance rams 16, 17 and an hydraulic control valve 15. To enable steering of wheels 5, 6 during on-site use, a lever (50), Fig. 2 (not shown), is moved to disconnect the steering wheel 10 from the power-assisted mechanical steering system and to connect the steering wheel 10 to an hydraulic steering unit 40. The steering unit 40 is then operable by the steering wheel 10 to control hydraulic flow to rams 26, 27 arranged for steering wheels 5, 6. The wheels 2, 3 can be steered during onsite use, to enable four wheeled steering, by means of a pneumatic cylinder 31 operably connected to the control valve 15. A valve 23 reverses the connections between unit 40 and the rams 26, 27 when the crane superstructure is rotated through 180 degrees relative to the crane chassis.

[Also in Division G1] Orange light B2 from a lamp 15, Fig.1, is passed through a condenser 16 and over a master work piece 10M and is reflected by a partially reflecting mirror 13 on to a screen 14. At the same time green light B1 from a lamp 11 is passed through the mirror and over a test piece 10 to also illuminate the screen 14 so that overlapping shadows of the pieces 10M and 10 are cast on the screen. Thus, green or orange fringe areas indicate respectively either that the master article 10M is larger or smaller than the article 10 under test. The relative magnifications of the shadows is adjusted by a hand wheel 23 moving a support 18. In a modification the different beams are polarized in mutually perpendicular planes or circularly polarized in opposite senses. In Fig.2 (not shown) and Fig. 3, light from a lamp 24 is split by a plate 26 with a dichroic coating which passes wavelengths above 540 m and reflects wavelengths below 540 m so that transmitted beams B1, B2 of distinctive colours are emitted by the device 26. These beams are passed over the master and test pieces 32, 34 and are re-combined where they coincide by a further dichroic coated plate 28, shadows of the articles or pieces being thrown on to a screen (29) behind the lamp 24. Discrepancies between the articles are determined as from their colour fringes described for Fig. 1. In Fig.4 (not shown) a dichroic coated beam splitting mirror 38 and two ordinary mirrors 39, 40 are employed, an orange beam B3 and a blue/green beam 34 resulting. These beams and a re-combined beam are directed over articles 43, 45 and through a lens 41 on to a screen 42. If the articles are rotatably supported then corresponding sections of the articles may be compared. The screens 14, 29 and 42 are preferably translucent to allow observation to be made on that side remote from the incident beams.

Abstract: 1, 055,911. Measuring moisture content electrically. BRITISH CELLOPHANE Ltd. Nov.13, 1963 [Nov.23, 1962], No.44477/62. Heading G1N. In an apparatus for measuring the moisture content of a flexible moving sheet (e.g. cellulose film) the sheet passes around a roller 2 (Fig. 1) having conductive segments 8, 8', 8" by which a direct voltage is applied across a selected portion of the sheet width and the current flowing through the sheet is measured on a microammeter 19 (Fig. 2) being a measure of moisture content. To avoid film sticking to the roller surface because of electric charge, it is arranged that the arc of the roller surface in contact with the sheet is greater than the arc of a conductive segment and that the applied voltage is disconnected from the segments before the sheet leaves the segments. The roller comprises a plurality of discoinsulating 5 alternating with discs 6 (Fig. 2) (and detailed in Fig. 4 (not shown)) having a generally triangular conductive portion 7 bounded by insulating portions 7'. An insulating rod 10 passes through holes in the discs 5, 6 fixing them against relative rotation and orienting the segments 8, 8', 8" in respective lines. Brushes 12, slidably mounted on a rail 13, contact, for example, a selected pair of segments 8' so that a potential e.g. 1500 VDC is applied by segments 8 of the same discs to the sheet. Alternatively the roller may be hollow with internally located adjustable brushes and three measurements are made each revolution of the roller.
