Title: Method of and apparatus for producing a timed signal
IPC: H03K17/28
Filed: 1961-11-09
Abstract: 969, 867. Electronic counters. A KUCKENS. Nov. 9, 1961 [Nov. 17, 1960], No. 40147/61. Heading G4A. [Also in Division H3] A timed signal is produced by alternately feeding the outputs of two timing circuits to the first stage of a counter, and arranging a selected stage of the counter to interrupt the operation of the timing circuits. Referring to Fig. 4, application of a start signal over the "start-stop wire" causes flip-flop I to apply a signal to timing device 1. After a time determined by this device a changeover signal is fed back to flip-flop I to change its state, and apply a signal to timing device 2. After the time determined by this device, a further changeover signal is fed back to flip-flop I which again changes its state and in so doing provides an output to flip-flop II and to one fixed contact on the stage selector switch. If the selector switch is set to this contact, a stop signal is produced which arrests the switching action of flip-flop I after this first switching cycle. If the selector switch is not so set, flip-flop I performs a further switching cycle resetting flip-flop II which then provides an output to change the state of a third flip-flop and one to a second fixed contact on the selector switch. If the selector switch is set to this contact, the switching action will be terminated after the second switching cycle of flip-flop I. Further flipflop stages may be similarly cascaded to give a time period equal to any number of switching cycles.  In a practical embodiment, Figs. 3a, 3b operation of the starting button 66 momentarily applied a voltage to the collector of transistor 70 energizing relay 64 to close contact 85 thus maintaining the collector supply to transistors 29, 45, 59, 70 and also to close contact 36. Transistor 17 then conducts producing a pulse via capacitor 4b which blocks transistor 2 and unblocks transistor 1. In the meantime capacitor 4b recharges via resistor 7a. After the period determined by the time constant of resistors 5, 6 and capacitor 4a transistor 1 again produces a pulse which switches flip-flop I back to its first state, thus causing a negative pulse to be fed via capacitor 35 to the second flip-flop stage, which now changes over to its second state. At the same time a negative pulse is fed via resistor 41 to the second contact of the selector switch, and if the switch is in this position transistor 69 is unblocked, blocking transistor 70 to release the relay 64 and terminate the timing sequence. If the selector switch is not in this position further switching cycles of flipflop I are repeated as described above. Fig. 1 (not shown) gives a basic time constant circuit in which the resistor 7a of Fig. 3a is replaced by a relay and Fig. 2 (not shown) gives a switching circuit comprising the time constant circuit of Fig. 1 with a single flip-flop stage in which the transistors 16,17 of Fig. 3 are replaced by diodes. The flip-flops may be replaced by other counting devices.

Abstract: 931,131. Supplying liquid fuel to burners. KUHLAPPARATE G.m.b.H. Nov. 30, 1959 [Dec. 24, 1958], No. 40662/59. Class 75 (1). Oil fuel is delivered periodically from a container 1 to a duct 3 leading to a dish burner 4 by an adjustable device and all the fuel delivered to the duct is delivered to the burner dish. In Fig. 1 the adjustable device is a wheel carrying pivoted buckets 11 which dip into the oil in the container and are tipped to deliver part of the oil into the duct 3 by adjustable pins 12 on the bottoms of the buckets engaging an adjustable stop 14 controlled for example by a thermostat. The pins 12 are of different lengths. At starting the thermostat moves the stop 14 gradually towards the periphery of the wheel as the temperature of the burner rises so that the buckets with short pins come to be tilted to increase the supply of oil to the burner. The wheel is rotated by a variable-speed motor or a synchronous motor. In Fig. 2 (not shown) the oil is raised by buckets pivoted on a chain driven by an electric motor. A counter records the number of buckets that have passed. In Fig. 3 (not shown) a single bucket is reciprocated in a tube immersed in the fuel container by a crank arm and connecting-rod driven by an electric motor. A projection on the side of the bucket abuts a stop on the duct delivering the fuel to the burner and causes the bucket to tilt so that the fuel therein flows into the delivery duct. In Fig. 4 (not shown) a single bucket is pivoted by a crank arm and a connecting-rod and a gearwheel pump continuously raises the oil from the container and directs it into the bucket. Oil overflowing from the bucket is led back to the container and when the bucket tilts all the oil it contains flows into a duct leading to the burner. The length of the crank arm and its speed of rotation are variable. A time control may switch the oil conveying device on and off periodically.

Abstract: 1,211,389. Current switching logic circuits. TOKYO SHIBAURA ELECTRIC CO. Ltd. 29 Aug., 1968 [31 Aug., 1967], No. 41325/68. Heading H3T. An integrated current steered logic circuit comprising an input transistor 23, a threshold determining transistor 27 and a constant current transistor 28 connected in common to their emitters has the base of the transistor 28 biased at 2BE and the base of the threshold determining transistor at 3/2 BE or 5/2 BE (where BE is the value of the emitter-base voltage drop in a conducting transistor), the bias values being determined by conducting P-N junctions shown as diodes but in the embodiments consisting of transistors having their collector and bases strapped. The base potential of 28 is set at 2BE by 42 and 43 and its emitter potential is thus BE. Accordingly the voltage across resistor 29 is also BE. If resistors 32 is equal to 29 the voltage at the base of output transistor 33 will therefore switch between BE when 27 is conducting and zero when non-conducting and the output voltage at 36 will switch between BE and 2BE due to the added e-b drop of transistor 33. A suitable switching threshold for use in interconnected circuits of this type is therefore 3/2BE. This is provided at the base of 27 by adding to the emitter-base voltage drop of transistor 45 the voltage from a potentiometer 39, 40 providing half the voltage drop across 44. The use of similar base-emitter junction throughout, provides a circuit insensitive to supply variations. The threshold voltage may alternatively be provided by taking half the voltage across three emitter-base junctions (52-54, Fig. 4a, not shown) and the bias voltage for 28 may alternatively be provided (Fig. 4b) by subtracting from the voltage across three emitter base junctions (60-62) the emitterbase voltage across a transistor (65) in series with 45. OR and NOR logic functions of the inputs as A1-A4 is provided at the collectors of 23 and 27. The inputs may alternatively be provided by emitter follower having their outputs connected in parallel to the base of 23 (Fig. 2, not shown). In this case the switching threshold at the base of 27 must be 5/2BE. This increased potential may be obtained by inserting an extra emitterbase junction between earth and the junction of 39 and 44, or as in Fig. 4c (not shown), by the addition of two emitter-base junction voltage drops (130, 131) to half the drop across a further emitter base junction.

Headings H2A and H2J. [Also in Division D1] A washing machine is controlled by one or several programme devices which are mounted on a shaft driven by an electric motor through a unit having a variable transmission ratio. When it is desired to blank parts of the programme, the speed of the shaft is increased by altering the transmission ratio, such alteration being effected by an armature mounted on the field structure of the motor and responding to increased magnetic flux therein. A control motor having winding S1 drives cams SM1., SM2, SM3, for periodically reversing the motor driving the washing drum, the latter motor having windings W1, W2, W3. At intervals, cam SM2 energizes winding S2 of the control motor to increase the flux therein and to advance the programme control shaft until, under normal conditions, contact s, k opens. Operation of the key T1, for example, maintains energization of winding S2 through contact ek1 after contact sk has opened, so prolonging the period during which the programme control shaft is rapidly advanced. Keys T2, T3 operate in a similar manner. The control motor may have a single tapped winding part of which is shortcircuited when it is desired to increase the speed of the control shaft, the motor being of the twopole type with stator extensions provided with short-circuiting rings and adapted to co-operate with a pivoted armature. In another arrangement, a winding of the control motor is connected in series with a capacitor when an increased motor flux is called for. The means for changing the transmission ratio of the programme controller may comprise a second rotor on the control motor which turns against the force of a spiral spring when the stator flux is increased above the value required for lowspeed operation. In another embodiment, a spring-biased armature is mounted pivotally on a stator stack within a winding of the control motor, the stator having an extension in the form of a lug. When the current through the winding is increased, the armature is attracted towards the lug.

A magnetic drum store in which the data words in a number of tracks are read in sequence and rewritten with or without modification depending on control bits in part of the word read has an auxiliary track with shorter recirculation time between read and write heads on which data from one of the tracks is duplicated so that the control bits of each word for processing are available at the previous word time.
