In a flame failure detector removal or reduction of illumination on a cadmium sulphide photoresistor, due to a flame extinction, causes relay RL to release and by opening of contacts RL 2  closes the fuel injection system and by contacts 17 of pair RL 3  operates an alarm. By means of a variable shunt resistor R 2 , applied to the relay when it operates, only a holding current flows through the relay, the size of which determines the amount of illumination reduction before the relay releases: resistor RV controls the illumination at which the relay operates. Push button SW switches on the fuel 11 and ignition 12 system for starting the burners. The relay is energized by rectified A.C.

Abstract: 1442870 Making drill chuck nuts; chucks; milling BLACK & DECKER MFG CO 19 Nov 1974 [21 Nov 1973] 50051/74 Headings B3A B3B and B3K A method of making a drill chuck nut 19 comprises forming a hollow chuck nut body, cutting a pair of diametrically opposed breaking slots 47, 49 in the hollow body, cutting internal threads 25 in the body at a predetermined angular location with respect to the breaking slots, and breaking the body at the slots to form a pair of semi-cylindrical nut parts 21, 23. The chuck nut is formed from bar stock 51 in a six spindle automatic screw machine, the first three stations of which progressively shape the hollow body in a series of facing, drilling and turning operations, Figs. 2-4 (not shown). At the next station, milling cutters 60, 62, in a rotating head 63, Fig. 5, form the breaking slots 47, 49. The stock 51 and head 63 are rotated through a gear train drive 64 while the head 63 is moved linearly also by a cam feed powered from the gear drive train. At the next station, Fig. 6 (not shown), the gear drive train 64 rotates a thread cutter (65) and continues to rotate the stock 51, so that the threads 25 are accurately positioned relative to the slots 47, 49. The cutter follows a rectangular path (66) and it may require multiple passes. At the final station a cut-off tool (67), Fig. 7 (not shown), parts the formed nut 19 from the stock. Grooves are then cut in the face 34 of the nut to form teeth 32, Fig. 1, and the nut is broken into the parts 21, 23, which are placed on the chuck body 13 over the already assembled jaws 15. Finally a retaining sleeve 45 is pressed over the nut parts 21, 23.

[Also in Division F2U] In a collapsible steering column for a motor vehicle comprising a tubular casing 10 housing a steering shaft formed by two telescoping shaft parts 11, 13 one of which is axially fixed relative to the casing 10 and the other of which carries the steering wheel 19, a hollow deformable member 18 positions the shaft part 13 relative to the housing 10 or the shaft part 11, and the shaft parts 11, 13 are connected by means which transmit the steering force without backlash and also provide a frictional force resisting collapse under axial load. The frictional resistance decreases progressively to offset the increasing force required to crush the deformable member, whereby a uniform resistance to the axial force may be provided. The shaft part 11 is supported in the casing 10 by a ball bearing 12, and the shaft part 13 is journalled by a ball or needle bearing 22 in a disc 21 connected to the casing 10 by the deformable member 18. A bush 17 on the shaft part 13 is slidable in the shaft part 11, and a collar 14 formed on the shaft part 13 is constrained with a predetermined frictional force applied by a tolerance ring 15 secured in a recess 16 in the shaft part 11. A pin 25 in the shaft part 13 engages a slot 26 in the shaft part 11 to transmit rotational forces greater than can be transmitted by the tolerance ring 15. In another embodiment (Figs. 3, 4, not shown) the shaft part (13b) is connected to a hollow square-section shaft part (11b) by two rectangular couping members (34, 35) having co-operating inclined surfaces (36) and spring-loaded into frictional engagement with the part (11b), a shear pin connecting the coupling members to the shaft part (13b) being fractured by a predetermined axial load. In a further embodiment (Fig. 6, not shown) a plastics coating between a hexagonal collar on the shaft part (13c) and a hollow hexagonal portion of the shaft part (11c) includes a bead which engages a groove in the part (13c) and fractures under a predetermined axial load.

Abstract: 1,267,979. Television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 17 Oct., 1969 [21 Oct., 1968], No. 51113/69. Heading H4F. A sync. separator comprises an amplitude limiter to which the video signal is applied and the output of which is coupled to the base of a transistor forming a clipping stage, the output of the separator being taken from the collector of the transistor, and the emitter of the transistor being D.C. coupled to an R.C. network, having a short time constant relative to the period of the field sync. pulses, and to a biasing electrode in the amplitude limiter. As shown, Fig. 1, the video signal 4 is applied to the emitter of transistor 1 constituting the amplitude limiter, the collector of which is corrected to a clipping stage 2 comprising transistors 7 and 8 connected as a Darlington pair. Line sync. pulses appear at the collector of transistor 8, the emitter of which is coupled to an R.C. network 10 which supplies the biasing voltage to the base of transistor 1 to control the limiting level.

Abstract: 1,187,607. Frequency modulation. R.C.A. CORPORATION. 10 Nov., 1967 [30 Nov., 1966], No. 51216/67. Heading H3R. A frequency modulator comprises a switch 25, 26 connected between an oscillator, point C, and a source of modulating signal, point A, the switch being operated during alternate half cycles of the oscillator frequency. If the potential at A is the same as that at C, actuation of the switch 25, 26 will have no effect on the operation of the circuit. If the potential at A differs from that at C, actuation of the switch will apply to point C a signal at the oscillation frequency whose amplitude depends on the difference between the potentials at A and C and whose phase will be 0 or 180 degrees depending on whether A is greater or less than C. This signal is equivalent to shunting the tuned circuit 21, 22 with a positive or negative reactance whose magnitude is proportional to the difference between the modulating potential at A and the fixed potential at C.

Title: Burner control systems

Filed: 1970-10-28
Abstract: 1316649 Burner ignition and control HONEYWELL Inc 28 Oct 1970 [11 Dec 1969] 51245/70 Heading F4T Burner control apparatus comprises a purge timer 50 to time a purge period prior to ignition of a pilot burner, and a flame sensor 15, preferably an ultra-violet detector or flame rod, such that if flame is sensed during the purge period or if flame is extinguished after ignition the apparatus is locked out by operation of safety switch 40 and associated heater 42, thus requiring manual resetting. In operation, on a demand for heat, power is supplied via controller 19 to energize transformer winding 25 and secondary windings 26-28 thereby establishing a D.C. supply, by means of diode bridge 37, to relay 3R and heater 42. Energization of relay 3R closes contacts 3R1 and 3R2 to operate fan motor 11, and air switch 35 closes under sufficient air flow from the fan to energize purge timer 50 via contact 4R2 to allow unburnt fuel to be purged before ignition. When the purge period ends, timer 50 produces an output on conductor 51 to pull in relay 1R and thus close associated contacts 1R1, 1R3, 1R4 and open contact 1R2, thereby opening pilot valve 12, energizing ignition means 13, and energizing heater 42 so that unless ignition is sensed within a set time period switch 40 will turn off the system. Upon pilot burner ignition, flame sensor 15 produces a signal which is amplified by amplifier 30 to turn on transistors Q1 and Q2 to trigger thyristor Q3 into conduction, thus energizing relay 4R, and flame relay 2R through closing of contact 4R1, to close down the ignition means 13, open main burner valve 14 by contact 2R3, open contacts 2R1, 4R2, 4R3 and close contact 4R4. If after ignition flame fails transistor Q2 is turned off and relays 1R and 2R de-energized, their associated contacts turning off valves 12 and 14 and the ignition means 13, closure of contact 1R2 causing heater 42 to eventually lock out the system. If flame is sensed during purging, conduction of transistors Q1 and Q2 energizes relay 4R before energization of relay 1R by timer 50 and thus contact 4R4 is closed while contact 1R2 is still closed, thus completing a circuit to heat safety switch 40 to lock out the system.
