Patent GB-460352-A (GB)
Abstract: 460,352. Postmarking and like machines. HASLER AKT.-GES. WERKE FUR TELEPHONIE & PRAZISIONSMECHANIK. June 2, 1936, No. 15415. Convention date, July 3, 1935. [Class 100 (ii)] Stopping, starting, and like arrangements.-In postmarking and like machines, a rotatable marking-cylinder is driven in conjunction with an endless conveyer for articles to be franked and is arranged to be automatically stopped at the completion of each rotation, and pressers arranged in longitudinal series above the conveyer and adapted to be lowered to press an article on to the conveyer are connected with mechanism which acts to release the cylinder after the pressers have been put into operation. The conveyer consists of belts 8, Fig. 2, mounted below a feed-table 1 on which is supported a manually-rotatable shaft 14. The shaft 14 carries a cam 18 engaging a finger 17 loosely mounted on the shaft and adapted, when rocked by the cam, to depress a plate 20 pivoted on a rod 21 and normally held in raised position by springs 23. Pivoted on the shaft 14 are pairs of levers 31, 32 carrying respectively rollers 33 and flat springs 34 which act to hold the articles on the conveyer; the levers are normally held in raised positions against the action of springs by the plate 20 and studs 24 carried thereby. In use, the article is placed on the conveyer, and the shaft 14 is rocked, thus causing the finger 17 to depress the plate 20 and permit the rollers 33 and springs 34 to grip the article. Rocking of the cam 18 permits a spring-pressed lever 37 secured to the rod 21 to fall so that the finger 17 engages a notch therein and is prevented from return. When the article is properly gripped, a lever f3, Fig. 4, which is carried by the shaft 14 and which has moved idly relatively to a link 11, rocks the link and releases a clutchoperating pawl 3 to set the cylinder 2 and conveyer into operation. Near the end of the rotation of the cylinder, a cam thereon rocks a lever 39 secured to the shaft 21 and causes the lever 37 to release the finger 17 so that the parts can be reset in normal position by spring action. The cylinder then resets the pawl 3 in position to disengage the clutch. Specification 459,266 is referred to.

Patent GB-1288416-A (GB)
IPC: H03K3/011
Filed: 1969-09-24
Abstract: 1288416 Transistor bi-stable; pulse modulation circuits PHILIPS ELECTRONIC and ASSOCIATED INDUSTRIES Ltd 24 Sept 1969 [27 Sept 1968] 46961/69 Headings H3T and H4L A bi-stable trigger circuit 1 having a pulsed power supply 39 and responding to the difference between an input signal applied to R4 and a reference potential at R6 (e.g. Ov), has the standing D.C. bias at the input electrode, T2 base, stabilized at the reference voltage level by a stabilization circuit including capacitors 15, 16 which are charged by the pulse source 39 to voltages dependent upon the respective collector voltages of T2, T3, so that if a difference builds up between the capacitor voltages due to a mean level at T2 base which is not the same as the reference level, this difference is used to vary the D.C. bias at T2 base so as to cancel the difference. The pulses from the source 39 are passed to the capacitor 15 or 16 through a gating diode 27 or 29 when the associated transistor 2 or 3 is off thereby reverse biasing a diode 26 or 28. A difference in capacitor voltages at the end of a given time period therefore means that the transistors 2, 3 have been conducting for unequal times in this period; in the Fig. 2 circuit, this is because the level 47 about which an input waveform 46 is equally distributed when considered over a period of time is not at zero volts. To remedy this, the difference between the capacitor voltages is obtained at 48 to control via 49, 50, 51 the D.C. level of the input signal. The waveform 46 may be the output of a p.c.m. arrangement 34, 35, 36, 40 operated in synchronism with the pulse source 39. In another embodiment (Fig. 1, not shown) the pulse source (14) feeds directly only the collector resistors 7, 8, and also feeds a divider 19 one output of which feeds for example every eighth pulse to the resistors 32, 33 and the other output of which disconnects the input waveform (5) from the base of T2 and earths the latter also every eighth pulse but slightly earlier. The capacitors (15, 16) are here connected through resistors (17, 18) directly to the bases of T2, T3 so that during each eighth pulse when both base resistors (4, 6) are earthed, any difference in base bias voltage causes one transistor to cut off and its associated capacitor therefore to be charged through the respective gate to annul the difference.

Abstract: 1,177,345. Automatic voltage control. MARCONI CO. Ltd. July 17, 1967 [Oct. 20, 1966], No. 47000/66. Heading G3R. A switched D.C. voltage stabilizer comprises a switching transistor 5 connected between input and output terminals; a timing capacitor 9 connected to be charged from the output side of transistor 5 by way of a resistor 10; a pulse source 1 providing pulses which are operative to render conductive the transistors 5; and a comparator including transistors 11, 12 which produces an output when the voltage on capacitor 9 attains equality with a reference voltage derived from a Zener diode 13, this output being operative to render transistor 5 non-conductive and also to discharge the capacitor 9 down to a voltage, less than the reference voltage, determined by a further Zener diode 14. The switching of transistor 5 is effected by a further transistor 4 connected both to the output from the pulse source 1 and to a bistable circuit 2, 3 which receives one input from the source 1 and another input from the comparator 11, 12 and which provides an output to control transistors 15, 16 in the discharge circuit of capacitor 9. The arrangement is such that the switching of transistor 5 is automatically controlled in a manner to maintain constant the output voltage of terminals "OUT". An auxiliary unswitched charging circuit for the capacitor 9 may be provided by way of a resistor 18 to give an added degree of stabilization against increases in input voltage.

Abstract: 1349310 Current amplifier PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 Oct 1972 [21 Oct 1971] 47923/72 Heading H3T [Also in Division G3] A current mirror amplifier S 1  comprises like conductivity transistors T 1 , T 2  having their base-emitter paths in parallel, the collector of transistor T 1  being connected to an input terminal A and to the base of a like conductivity transistor T 4 , the collector of which is connected to the base of a complementary transistor T 3  whose collector is connected to the bases of transistors T 1  and T 2  and whose emitter is connected to a supply voltage. The use of the additional transistor T 3  in the feedback path between collector and emitter of T 1  allows the circuit to operate from a lower voltage, e.g. 0À9 v. The gain is determined by the ratio of the emitter areas of transistors T 1  and T 2  and resistor R. Diode T 7  increases the current through transistor T 3  to increase the frequency response of the amplifier. Similarly, diode T 8  increases the collector current of transistor T 4 . If the diode T 9  is replaced by a constant current source the input of impedance of the amplifier is kept low during large signal swings and capacitance at the input terminal does not affect the phase response. Feedback from the input A to the output B of the amplifier S 1  via a unity gain amplifier S 2  stabilizes the currents into the amplifier S 1  so that collector currents of paralleled transistors T 1 , T 01 -T 04  are constant to provide stabilized current outputs. The amplifier S 2  may be identical to amplifier S 1  or the resistor R may be in the emitter path of transistor T 5 . The NPN transistors may be of lateral type.
