Rollers 4, 19, 20 keep the film engaged with the sprockets, 1, 7. Roller 22 is placed to ensure that in the rewind mode the elimination of loop 17 does not cause roller 4 to move away from the sprocket 1 by pivoting about shaft 3. In the rewind mode parts of the gate 5, 6 may be separated by a solenoid acting on pressure pad 6.

Title: Method and apparatus for suppressing the deposition of carbonaceous material in a coke oven battery
IPC: C10B21/20
Filed: 1975-11-26
Abstract: 1529817 Preventing deposition in coke oven flues KOPPERS CO Inc 26 Nov 1975 [26 Nov 1974] 48688/75 Heading F4B  In a regenerative coke oven battery, rich gas is mixed with a diluent gas in or upstream of the headers supplying the heating walls. The invention is shown applied to ovens having divided flues, hairpin flues or cross over flues (Figs. 1 and 2, Figs. 3, 4 and 5 and Figs. 6 and 7 respectively). A reversing arrangement, Fig. 8, enables some 25% by volume of diluent air to be supplied with rich gas from a main 24 to the header 123 connected to the "on" flues, while a larger proportion of air from a main 146 is supplied to the header 121 for the "off" flues to decarbonize the risers. Orifices 164, 172 in the air supply connections proportion the air automatically because of the greater pressure in pipe 140 supplying gas. The risers of the "off" and "on" flues may be interconnected to allow recirculation of the waste gases, and the reversing mechanism may be arranged so that the fuel gas is disconnected from both sets of flues during a short period while decarbonization air is fed through both sets of risers. In the embodiment of Figs. 9 and 10 (not shown), diluent air or gas is supplied to the risers to the off flues to mix with recirculated waste gas before it is fed to the risers to the "on" flues.

These compounds may be obtained by reacting a compound of formula wherein R 1 , R 2  and Ar have the same significance as above, with hydroxylamine hydrochlcride. The intermediate of Formula II is prepared by condensation in a benzenic medium of a derivative, suitably substituted in the 2-position of (4-chloro-pyrimidin-6-yl) ethyl acetate of formula in which Ar is the same as above, with an amine of formula in which R 1  and R 2  have the same significance as above.

Title: Radio or television receiver with an automatic station finding  arrangement
IPC: H03J5/02
Filed: 1974-11-12
Abstract: 1471712 Automatic station seeking receiver INTERNATIONAL STANDARD ELECTRIC CORP 12 Nov 1974 [16 Nov 1973 (2)] 48858/74 Heading H3Q In a stop on signal radio or TV receiver in which the tuning is determined by the output of a D/A converter 5, Fig. 3, controlled by the output of a counter 7 driven from a pulse generator 6 until stopped by sensing a received signal, a store 15, 16 and/or 26 for storing a particular output from the counter has an output connected to an input of the counter and circuitry is associated with a setting input P of the counter so as to selectively transfer the digital signal at the counter input A1-An to the counter output Q1-Qn. The tuning section 1 includes varacter timing elements and the pulse generator 6 is started by a button 11. On detection of a received signal an output from a demodulator in 1 operates a toggle 10 to stop the pulse generator 6. A recall data store including series connected parallel data stores 15 and 16 formed on an integrated circuit 25 functions on operation of a recall switch 29 to recall the tuning setting to the previously received station as stored in the store 16. The counter 7 is then set to the count of the bit word stored in data store 16 and the new count is entered into the store 15. A station tuning data storage device 26 can be provided which is disclosed in more detail in a car radio receiver embodiment as circuit (39, Fig. 6, not shown). The station on which the counter 7 is stopped can be written in a station data store (38 1 -38 8 ) by operating a station selector switch (37) and a write switch (46) to select via a storing code converter (54) and a switchable decoder (53) the store (38) associated with that selector switch such as (37 L ). The stored station can be recalled by pressing the selector switch (37 L ) the final pressing of which operates recall switch (47) so that the counter 7 is set with the bit word at the output of a selection matrix corresponding to the station stored in the associated data store (38). The station currently received is indicated by an indicator (57) fed from a binary to decimal code converter (56). Also a dial indicator (59) is formed of a band of light-emitting diodes along a frequency or station dial. To prevent the contents of the station memories from being lost in the "off" state of the receiver at least the station memories are always connected to a power source such as a battery 62. This also enables the station to which the receiver was tuned when the receiver was turned off to be tuned to on switching on the receiver.

[Also in Division H1] In a rotary spindle setting mechanism for a group of rotary switches or potentiometers 88, Fig. 3, in which the shafts 30 (A-D) are coupled through Geneva gears 45 (A-C), 46 (B-D), the coupling between the driven gears 46 (B-D) and the higher order spindles 30 (B-D) comprises a disengageable clutch, whereby these higher order shafts may be individually adjusted without moving the lower order shafts 30 and irrespective of their settings. In the example of Fig. 3, a slipping clutch comprises spring-pressed pins 60, Fig. 6, engageable with serrations on the shaft 30C and held by spring 62 engaged under extended gear-wheel teeth 64. Idler gears 48 (A-C) are arranged between the shafts to obtain the correct direction of rotation. In a modification each clutch comprises an axially yieldable idler gear 103, Fig. 9, having bevelled ends 112 on its teeth 102 engaging corresponding ends of teeth 107 on the driven gear 104 of a higher order shaft. The gear 103 yields axially against spring 108 when its rotation is prevented by the stationary Geneva driving gear 106 of a lower order shaft. In a further modification the Geneva mechanism gears 116, Fig. 10, are normally locked relative to the potentiometer spindles 118 by pins 122 on an electromagnetic clutch plate 124 whereby the spindles 118 are driven from the lower order spindles. Retraction of the pins 122 on plate 124 is however caused when individual adjustments are made to the higher order spindles 118 by a knurled knob 134 which has a lost-motion connection and first actuates one of a pair of micro-switches 132 through projection 140 to cause withdrawal of the clutch plate 124 against its return spring 143.

The short wavelength u.v. radiation is dissipated within the enclosure by the ozone formation so that the light emitted through a quartz or sapphire window 48 is substantially free of such radiation. The walls of the enclosure are provided with cooling fins 27, and a fan 52 may be provided to blow cooling air past the enclosure. An A.C. magnet 55 is mounted on the enclosure to cause the lamp arc to oscillate therby preventing localized heat deterioration of the cathode emission area. The housing may be adjusted vertically by a screw 51.

The motor driveshaft 1 drives a pulley 2 on which a connecting rod 3 is eccentrically pivoted. The end 7 of the lever 8 is pivoted on a threaded nut (5), Fig. 1 (not shown) which can be racked by a knob 12 along a threaded rod 6 in a groove 11 in the arm 4. Oscillation of the arm 8 is transformed via gears 10, 16 to the uni-directional clutch 17 which produces the intermittent rotation of the shaft 18. The shaft 18 is coupled, via the further, electromagnetic, clutch 19, to a threaded shaft 21 where rotation is transformed by the threads 22 into the intermittent translation of the support. The clutch 19 may be decoupled after a given number of oscillations, by a counter. The amount of translation, and hence the thickness of the slices, may be varied by adjusting the position of the nut (5) on the arm 4 or by varying the pitch of the threads 22. Alternatively, the length of the lever 8 may be varied. The slices are laid out in spaced groups on a conveyer belt, ready for packaging in groups.
