An electro-photographic machine comprises a device for scanning a document on a platen 22 illuminated by lamps LMPS and projecting an image on to a rotating drum 4. The device is generally similar to that described in Specification 1, 089, 536, but includes a movable lens 24 for varying the magnification of the device as des- - cribed in Specification 1, 223, 427, and a variable speed drive connection 250 between scanning mirror 23 and the machine drive. Upper or lower drive tapes 251, 252 respectively connect sectors 200 and 141, such that according to the tape rendered operative by a pneumatic cylinder 210 the scanning speed is varied. Actuation of the cylinder 210 actuates a bracket (201) Fig. 6 (not shown) which rocks a bell-crank lever (205) which rocks an arm (208) engaging a ramp (220) such that mirror 23, Fig. 2, is oscillated through the lower tape 252 at a greater angular velocity than the drum 1. When a 1:1 copy is required cylinder (210) is actuated to move the plunger (211) to move to its lowermost position, whereby drive is effected through the upper drive tape 251 to reduce the scanning speed and angle. Reference has been directed by the Comptroller to Specification 1, 089, 536.

Abstract: 1456639 Automatic control of temperature LUCAS ELECTRICAL Ltd 21 Nov 1973 [2 Dec 1972] 55798/72 Heading G3R [Also in Division H2] A cooling fan in a motor vehicle is controlled in dependence upon the engine cooling water temperature as sensed by a thermistor 15 Fig. 1 (e.g. P.T.C. type). The thermistor is in a control circuit within an electrically conductive casing 11 and in thermal communication with the coolant via the casing which may be mounted on the vehicle radiator. Below 90‹C a current insufficient to actuate a relay 25, 26 passes through the relay winding 25 via resistors 21, 24 and diodes 22 and via R16 and Th15, from the vehicle battery. At 90‹C the resistance of the thermistor increases rapidly and the volt-drop thereacross is sufficient to turn ON a transistor 19 which in turn causes a transistor 17 to turn ON. The main current through winding 25 is now via 17, 22, 23, 24. The resulting increase in current in winding 25 closes relay contacts 26 thereby switching ON the cooling fan motor 27. Since the volt-drop across the thermistor 15 also increases, it is necessary for the sensed temperature to fall below 90‹C by about 3‹C, in order to cause the relay to drop-out and switch off the fan motor. The thermistor has a separate earth connection to the casing so that if the thermistor becomes detached the fan motor will come ON and stay ON thus giving a warning. The transistors 17, 19 are regeneratively inter-connected.

Abstract: 1,193,477. Digital transmission systems. WESTERN ELECTRIC CO. Inc. 19 Dec., 1967 [27 Dec., 1966], No. 57548/67. Heading H4P. A circuit for deriving a timing signal from received digital signals, in which during each digit interval the frequency changes smoothly from a base frequency to a higher or lower frequency and back to the base frequency, comprises means 10, Fig. 1, for dividing the signals into two equal components and for delaying (17) one relative to the other by less than one digit interval, the delayed and undelayed components being combined (11) to produce two outputs whose amplitudes depend on the relative phase of the components. The two outputs are amplitude detected (14, 15) and the results are combined to provide the timing signal. The circuit may be combined with an F.M. differential phase shift receiver as described in Specification 1,193,475, Fig. 4 (not shown). In such a system the dividing means, which is a hybrid unit, is common both to the receiver and the timing circuit. One of the outputs of the divider passes through two delays in series, having a total delay of 1 digit interval as required by the receiver demodulator. The first delay 17 may be about 0À6 digit interval and it feeds both the second delay and the combining hybrid 11. the timing signal has a sinusoidal waveform of digit frequency and controls an oscillator which controls a regenerator in the receiver output.

The input to and output from the filter 91 are fed to a phase comparator 93 (Fig. 10) developing an output voltage proportional to the phase difference, which is amplified at 101 and fed to the gate of FET 106 to vary its effective resistance. The transistor 106 is part of a filter network associated with amplifier 95 in filter 91, and the variations in its resistance produces the appropriate changes in the pass band necessary to bring the phases of the input and output of filter 91 into agreement. The oscilatory frequency is thus automatically maintained at the fundemental of the tuning device 10.
