Abstract: 1,245,459. Controlling burners. HONEYWELL Inc. 11 Oct., 1968 [30 Oct., 1967], No. 48385/68. Heading F4T. In a burner control system including a spark ignition apparatus and flame detecting means sensitive to radiation common to a spark and to a flame, interference between the radiation of the ignition spark and that of the flame is prevented by constructing the spark ignition apparatus to generate a constant frequency recurring spark producing voltage, and having the flame detecting means synchronized so that it is only sensitive to the radiation during the recurring periods when a spark is not being generated. As shown, the flame detector 30 is sensitive to ultraviolet radiation and is connected to the same A.C. source 20, 21 which energizes the spark igniter 10, the primary windings of the transformers 11 and 31 being selected so that during the half-cycle when diode 33 applies operating voltage to Geiger tube 32, thereby enabling it to detect ultraviolet radiation, diode 13 prevents the application of a spark-producing voltage to electrodes 12 and no spark is produced at these electrodes.

Title: Electric motor supply circuit
IPC: G11B15/46
Filed: 1969-10-09
Abstract: 1280214 Automatic speed control INTERNATIONAL BUSINESS MACHINES CORP 9 Oct 1969 [15 Oct 1968] 49662/69 Heading G3R An electric motor is controlled by a speed sensing feedback circuit. A manual switch can also be operated to energize the motor directly independent of the feedback circuit. The example described is a dictating and playback system of the type in which a signal is recorded in a helical path on a magnetic belt. The belt is placed in a transcribing unit, for playback by an operator using a foot control switch. The regulating circuit for the transcribing unit is shown in Fig. 7, details of the circuit and associated switches being given in Figs. 5a and 5b (not shown) The unit is driven by a D.C. motor 105a in series with an amplifier 280 comprising a pair of Darlington-connected transistors. The motor drives a tachometer 273, the output of which is fed through a limiter 281 and single-shot circuit 282, each comprising a pair of transistors, to produce pulses of fixed duration which are integrated by a filter 283 which acts as a Miller integrator and includes a further transistor. The resulting output is compared with a fixed reference supply and used to control the transistors in amplifier 280. In normal operation, that is, during playback of the belt, the voltage applied to the motor is restricted by the feedback circuit to a about 6 volts. However, when the belt is first loaded, phase switches are operated by the foot control and the motor is connected directly to earth and operates at the full voltage of 16-18 volts independent of the feedback circuit to register the beginning of the belt rapidly. Similarly, the belt is cleared after use by pressing an erase button which drives the belt rapidly for one revolution. Further switches are provided to allow the belt to be stepped in movements in either forward or reverse directions, and after playback the belt is automatically repositioned so that the last few words will be repeated when the belt is next used. The operation of the dictation unit is similar, and the construction of the whole system is described in Specification 1224909.

Abstract: 1,047,950. Axial-flow blowers. DINGLERWERKE A.G. Dec. 18, 1963 [Dec. 21, 1962], No. 50035/63. Heading F1C. An adjusting mechanism for the angular setting of the rotor blades of an axial-flow blower or the like is carried inside a stationary casing supported by the rotor, and comprises a member adapted to be shifted along the rotor axis, with its longitudinal position controlled from the outside of the casing, so as to move a further member coaxial with the rotor, rotating in unison therewith and adapted to adjust the angular setting of the blades in accordance with its longitudinal position. The shaft 2 of the rotor 1 of an axial flow blower is journalled in bearings (not shown) and the rotor supports a stationary casing 11 through a ball bearing 12 and a hub 10. The spindles 3 of the rotor blades 4 are connected through cranks 5 to an adjusting disc 7 which rotates with the rotor and is connected through a ball bearing 8 to a rod 9 so as to be movable axially with the latter to adjust the blades. For this purpose the rod 9 is movable axially by bell cranks 14 which are turned in opposite directions by nuts 16 engaging threads of opposite hand on a rod 17 which is turned by an articulated shaft 18. With this arrangement, there is no additional end-thrust exerted on the rotor shaft bearings during adjustment. In an alternative arrangement, the axial movement of the adjusting disc 7 is produced by a crank and connecting rod, or an eccentric mechanism, the crank or eccentric being turned by means of an articulated shaft or by means of a lever mounted on an extension of the shaft projecting outside the stationary casing. The angular setting of the articulated shaft or shaft extension may be transmitted to a remote station to provide an indication of the angular setting of the blades.
