Title: Tuning arrangements for radio transmitters
IPC: H03J5/24
Filed: 1973-07-11
Abstract: 1439516 Automatic control of position HATFIELD INSTRUMENTS Ltd 11 July 1974 [11 July 1973] 32992/73 Heading G3N [ Also in Division H4] In a radio transmitter tuner arrangement settable by a multi-position selector switch, a first section of the switch is arranged to control an inductance in series between the power amplifier stage of the transmitter and the aerial and a second section of the switch is arranged to control a capacitance in shunt with the inductance and aerial at the output of the power amplifier. Each of the contacts of the two switch sections is arranged to be connected to a respective first or second actuator such that energization of a given contact cause the respective actuator to appropriately adjust the respective inductance or capacitance. The multi-position switch has two banks 7b 7c respectively controlling a variable capacitor 9 and inductance 10 which time the transmitter. The switch arms are connected to negative potential and the switch contacts to conductors e.g. 13a in turn connected to further conducts e.g. 13b. For the variable capacitor, these further conductors connect to the contacts 14a of a switch 14 whose wiper is connected to a Darlington circuit 15, 16 which controls a motor 17 driving the capacitor and the switch arm. The motor drives the arm 14b until it reaches the contact to which the negative potential is applied. Controlling the inductor is a contact bank 24 with movable contact 24c contacting all the contacts except one. This is driven by a stepping motor 25 until the contact to which negative potential is applied is not contacted.

Abstract: 1,249,572. Ventilating motor vehicles. SOC. ANON. FRANCAISE DU FERODO. 1 July, 1969 [5 July, 1968], No. 33233/69. Heading F4V. [Also in Division H1] An air supply device for a motor vehicle comprises a duct including a pivoted flap 14 controlled by a pivoted cam 22 and a follower 28, and a fan driven by an electric motor which is in circuit with a variable resistor 33 carried by the cam 22 and slidable across a fixed contact 34. As the cam 22 is rotated clockwise from the position shown, the flap 14 is first pivoted to its fully open position with the fan motor inoperative, and then the flap 14 is held open while the fan motor is started and its speed progressively increased. In another embodiment, the fan is started before the flap 14 is fully open. A heating heat exchanger may be provided in the air duct. The flap 14 may be locked in its fully opened and closed positions by magnets to prevent vibration.

In an airport lighting system having lamps connected in series by transformers 2 fed from a source through a selfsaturating transductor 1, a high transformer secondary voltage on open circuit is avoided by having a C-shaped transformer core of substantially rectangular shape hysteresis loop operated in the saturation range and the transductor giving a distorted output current such that over the first part of each half-cycle the current rises relatively slowly, until in the saturation range, and subsequently rises to a sharp peak value before falling to zero. The transformer magnetizing current corresponding to the maximum change of flux is also made substantially equal to the minimum output current of the reactor.

Title: Improvements in or relating to power-take-offs for use with tractors
IPC: B60K17/28
Filed: 1945-12-10
Abstract: 602,144. Driving auxiliary apparatus. FERGUSON, Inc.. H. Dec. 10, 1945, No. 33275. Convention date, Jan. 25. [Class 79 (ii)] A power take-off unit for tractors of the type having a transmission case with a rear opening through which rearwardly projects a propeller shaft fast with the crankshaft, i.e. independently of the tractor transmission shaft and clutch, comprises a unitary housing boltable to said rear opening, and supported in the housing a power take-off shaft, one end of which carries a clutch supported and driven by the rear end of said propeller shaft, and means for applying and releasing pressure to the clutch members such means being located wholly in or upon the housing. The clutch may be of the selfenergizing type and its operating means may be a rod which passes longitudinally through the power take-off shaft. As shown in Fig. 1. the engine crankshaft 1 drives the normal flywheel 2, clutch 4, tubular shaft 5, change speed gears 6-9, shaft 10, pinion 13 and differential crown wheel 14. Attached directly to the crankshaft 1 is a propeller shaft 20 which drives through a self-energizing clutch 24, Fig. 3, the shaft 31, bevel-gears 37, 38 and hence the transverse power take-off shaft 57 carrying belt pulley 40. The shaft 31 also drives through spur gears 41, 43 a second power take-off shaft 44, whose splined outer end is protected by the pivoted guard 66. The clutch 24, which controls both take-off shafts, comprises an annular ring 25 fast with the housing 24 and propeller shaft 20, the ring having clutch facings 26. On one side of the driving disc 25 is the driven member 28 and on the other side is the driven member 27 fastened by cap screws 32 to the member 30. Interposed between the members 30 and 28 are light springs 29 which serve merely to maintain the driven members 27, 28 in light contact with the driving disc 25. When the drive is taken up by the clutch the members 28, 30 undergo slight relative rotation which causes the balls 34, held in conical seatings, to force the driven members 27, 28 into tighter contact with the driving disc 25 and so to transmit full load. The clutch can be released by rearward movement of the lever 53, Fig. 4, which rotates shaft 52 and causes cam 55 (see also Fig. 3) to act on the thrust race 56 to withdraw the rod 57 and so compress the clutch springs 29 to declutch. Such a layout of the clutch and its actuating lever permits the whole device to be made as a self-contained unit for bolting on to an existing tractor.

An arcuate slot 10 in the cam-ring has a block secured at one end which is adapted to engage a plunger 9 having opposite flat faces 12 arranged at different distances from the axis of the plunger to set the ring in position for roughing or finishing cuts on rotation of the plunger. The plunger is rotatably mounted eccentrically in, and parallel to, the axis of a bush 13 which is rotatable in the head. A pin 14 traverses a slot 15 in the bush and is engaged by two screws 16 which serve to rotate the bush and adjust the position of the plunger 9 to determine accurately the cutting position of the camring. Rotation of the bush is limited by the ends of the slot 15 engaging the screws 16. Opening of the head is effected by axial movement of the plunger 9 against its spring.
