Abstract: 995,658. Reverse gear control. SMITH'S (HARLOW) Ltd. July 16, 1963 [July 16, 1962], No. 27259/62. Heading F2D. [Also in Division B7] An inboard/outboard drive unit for vessels (see Division B7) has a gear-box controlled by a gear control member which extends into a housing 2 enclosing a driving shaft 1 and is connected to a selector fork 45 by a Bowden wire cable lying entirely within the housing 2 and the gear-box casing 18. As shown, a shaft 58 is fitted to a pulley 54 around which a pair of Bowden wire cables are fitted. The other ends of the cables are connected to a selector fork 45 such that movement of the shaft in one direction causes one of the cables to be pulled, and moves the selector fork in one direction so that one of the dogs, say, dog 31 of dog clutch 30, engages a dog 33 on a bevel gear 25. Thus the gear 25 is driven, and in turn drives a gear 35 and a vertical shaft 36. Movement in the opposite direction of the shaft 58 causes a dog 32 to engage a dog 34 on a gear 26, thus reversing the drive to the shaft 36. A rocker arm may be used instead of the pulley 54. Steering is facilitated by means of a linkage 60, 63, 64 which swings the gear-box and associated parts about the vertical axes of universal joints connecting the driving shaft 1 to the gear-box input shaft 22, and the housing 2 to the casing 18.

Abstract: 616,846. Radio receiving circuits; frequency modulation. PHILIPS LAMPS Ltd. Sept.13, 1946, No. 27541. Convention date, April 21, 1943. [Class 40 (v)] A superheterodyne receiver for the reception of medium frequency broadcast signals and also of short-wave signals having a broad bandwidth (e.g. F.M. signals) and having one or more I.F. stages which are used for both types of signal and a further I.F. stage used only for S.W. reception, has the change of connections of the I.F-. amplifier when switching from S.W. to M.F. reception effected solely by rendering one of the valves of the further stage inoperative. The further stage compensates for loss of gain due to wide band operation during S.W. reception. The figure shows the circuit diagram of an I.F. amplifier for medium frequency broadcast signals and also for wide band, shortwave frequency modulation signals. With short waves, frequency changer 1 produces a 10 mc/s I.F. signal which passes through coupled circuits 2, 4 to a first amplifier valve 5, the output of which is coupled through circuits 6. 7 to a second amplifier valve 9 which passes the signal through circuit 10 to a limiter 12 followed by discriminator 13. The resulting modulation signal is passed through switch 15 to output terminals 16, 17. At medium frequencies the frequency changer produces a 450 kc/s signal which is selected in circuits 3, 8 and byepassing first amplifier valve 5 is applied to second amplifier valve 9, the output of which is selected in circuit 11 and detected by diode 14. The change from 10 mc/s to 450 kc/s operation of the I.F. amplifier is effected solely by interrupting the cathode circuit of valve 5 by means of a switch 20 coupled to the wavechange switch of the receiver.
