Title: Television tuner input circuit

Filed: 1965-11-15
Abstract: 1,117,258. Radio receiving circuits; R.F. couplings. OAK ELECTRO/NETICS CORPORATION. 15 Nov., 1965 [13 Nov., 1964], No. 48309/65. Headings H3Q and H4A. An input circuit for a radio receiver tuner for operation in either of two frequency bands comprises a balun 15 in series with one input, which is balanced, an impedance matching step-up transformer 25, for connection to an R.F. amplifier 28, and circuit means including a switch 23 for connecting either input to the primary of the said transformer. As described, in a television tuner for the V.H.F. and U.H.F. bands an aerial 10 receives V.H.F. signals which are connected by a 300 ohm balanced transmission line 11 to the balun 15, whose unbalanced output side has an internal impedance of 75 ohms, and then via contact 54 and the arm of the switch 23 to the primary 26 of the transformer 25. The secondary 27 of the transformer is connected to the grid 33 of a triode valve used in the amplifier 28 and, via a neutralizing capacitor 40, to the anode 34, thereof. A capacitative voltage divider 36, 37 across the said secondary 27 allows its virtual centre to be connected to the cathode 32 of the triode and to earth, and a variable inductor 38 across it is for channel tuning. The output from the amplifier 28 is taken to one input of a V.H.F. mixer 29 and the output of a variable local oscillator 30 to the other. The output of the mixer 29 is at the I.F., 39 to 34 Mc/s. U.H.F. signals are received on an aerial 45 and are connected by a cable 46 to a U.H.F. tuner or converter 47 whose output is at the I.F., 39 to 34 Mc/s., and whose internal impedance is 75 ohms, unbalanced. When the arm of the switch 23 is on the contact 55, these signals are coupled into R.F. amplifier 28 and they are additionally amplified by the mixer 29, the local oscillator 30 being then disabled. A channel input network 50 may be interposed between the U.H.F. tuner 47 and the switch 23 and a high-pass filter, with a cut-off frequency of 34 to 40 Mc/s., may be interposed between the balun 15 and the switch 23.

Filed: 1965-11-15
Abstract: 1,156,327. Fuel injection pumps. C. A. V. Ltd. Oct.31, 1966 [Nov.15, 1965], No.48372/65. Heading F1A. [Also in Division G3] In a fuel injection pump having a throttle member 20 controlling the fuel output and a fuel pressure operable piston 24 controlling the timing, the throttle member controls a port 27 in the fuel flow path to the timing piston cylinder including a restriction 30 downstream of the throttle member, such that variations in the setting of the throttle member will produce variations in the timing. The pressure upstream of the restriction 30 and the bias of spring 26 are applied to the piston 24 in opposition to the outlet pressure of the feed pump 17 which varies in accordance with driving speed. The feed pump pressure acts on the piston 24 via passage 18 and check valve 25. The restriction 30 communicates with a drain and fuel is supplied upstream thereof from the feed pump via passage 18, restriction 28, port 27 and passage 42. The pressure upstream of the throttle 20 is maintained substantially constant by a valve 29. The throttle 20 is moved against the bias of an adjustable governor spring 23 by the outlet pressure of the feed pump acting on its inner end. In a further embodiment, Fig. 3 (not shown), the pressure downstream of the throttle controlled port (27) acts on the timingpiston in opposition to the spring-bias and the passage connecting the port to the timing piston cylinder is connected to a drain through a restriction (30). The feed pump outlet pressure does not act on the timing piston and the pressure upstream of the throttle controlled port (27) is maintained substantially constant by a valve (29). In a modification of the embodiment of Fig. 3, Fig. 4 (not shown), the port (31) to the timing cylinder is controlled by the inner end of the throttle member (20) and the constant pressure valve is omitted. In another embodiment, Fig. 5 (not shown), the fuel from the feed pump acts on the inner end of the throttle member (20) via a constant pressure drop valve (32) and a centrifugal regulator (33) which spills fuel to provide a pressure which varies in accordance with the square of the speed. The pressure acting on the timing piston is controlled by the throttle controlled port (34) and a by-pass downstream of the throttle member (20) and upstream of the timing cylinder which is connected to the passage between the constant pressure drop valve (32) and the throttle member. In a modification of this embodiment, Fig. 6 (not shown), fuel is supplied to the engine via the constant pressure drop valve (32) and a passage in the throttle member (20).

Abstract: 1405492 Measuring dewpoint electrically IMPERIAL CHEMICAL INDUSTRIES Ltd 16 Oct 1973 [26 Oct 1972] 49465/72 Heading G1N Apparatus for determining the dewpoint of a gas comprises a glass thimble 2 containing a thermocouple 3 and an electrode 4 and a conduit 9 fed with cold air. A potential difference is applied between the thermocouple 3 and electrode 4. When the thimble is cooled by the air in conduit 9 below the ambient dewpoint a current flows between the elements 3, 4, which current is fed through a relay 10 to cut off the cold air-flow at a pre-set value. The temperature then rises and the current falls as the dew is evaporated until, at another pre-set value, the relay 10 restores the airflow through conduit 9. Thus the temperature of the thimble 2 oscillates about the dewpoint value and is indicated at 8, recorded at 12 and actuates an alarm 13 at a maximum value.

Abstract: 1,130,384. Ratchet gearing. MALLORY TIMERS Ltd. 4 Nov., 1966 [16 Dec., 1965], No.4962.3/66. Heading F2Q. In a drive mechanism for a timer having cams 27 on a shaft 26 controlling electrical switches (not shown), a ratchet wheel 25, secured to the shaft 26 and advanced by a tang 23 on a drive member 20 pivotally and slidably mounted on a narrow portion 38 of the shaft 26 by means of a slot 37, is driven at one speed with snap action advancement to drive the cams during a programmed timing cycle, and at a higher speed for rapid advance to or through a particular cycle. For the snap action drive, a motor 11 drives a cam 16, through gears 14, 15, to act on a roller follower 22 on the member 20. The cam moves the member 20 against the force of a spring 18, and then releases it for a rapid driving stroke under the power of the spring 18. For the rapid drive, a motor 34 drives a cam 29 through gears 30-33 to rock the member 20. In an alternative arrangement (Figs. 4, 5, not shown) the second motor 34 and cam 29 are replaced by a solenoid (39) acting on an armature (43) mounted on the member (20). A saw-tooth cam (41) on the shaft of the motor (11) acts on a switch (42) to cyclically energize and de-energize the solenoid (43) to rock the member (20). Instead of the cam (41) and switch (42), an electronic pulsing device may be used to energize the solenoid (39). One of the cams 27 is included in the control of motor 34 or solenoid (39).

In the arrangement shown the potential difference from supply 12 is applied to the cell 5 and after a predetermined time e.g. 1.3 seconds timing circuit 20 switches current recorder 26 into the circuit to measure the current flowing. This current is much greater if a reducible passivating film is present than if a non-reducible passivating film is present, Fig. 2 (not shown). In an alternative arrangement Fig. 3 (not shown), the recorder 26 is replaced by a coulometer which measures the electrical charge flowing through the cell for a predetermined time e.g. 15 seconds beginning when the P.D. is applied.
