The arm can be set at a desired angular position by a sine bar 11 releasably mounted in a slot 14 in the slide 6. A stop 16 can be adjusted on a disc 19 secured to the spindle 3 to contact a finger 20 on the base to position the arm at the set angle. The arm can be set at an opposite angle using the sine bar and positioned by a second adjustable stop on the disc. Swivelling of the arm is effected by a handle 21 for radius dressing of the wheel and angle dressing at each of the positions determined by the stops is effected by reciprocation of the slide 6 by the knob 9. In another embodiment, the rack-and-pinion mechanism 7 is connected by a universally-jointed shaft to a knob adjacent the handle 21. In a further embodiment, the slide 6 can be locked in a central position by a spring-loaded plunger.

Abstract: 1,161,205. Automatic frequency control systems. PLESSEY CO. Ltd. 23 Sept., 1966 [29 Sept., 1965], No. 41305/65. Heading H3A. The reference frequency in an automatic phase-control system is derived from a lowfrequency and from a high.frequency harmonic of a reference frequency, these two signals being applied directly and through 90 degree phase shift networks 2 and 3 to two balanced modulators 1 and 4, the outputs of which are combined to give a single sideband at either the sum frequency or the difference frequency according to the arrangement of the phase shifts. The sideband provides one input to a phase detector 6 controlling the oscillator 7 which provides the final output and the other input to the phase detector. The oscillator 7 may be swept in frequency initially by a sawtooth voltage which may be inhibited when the frequency is within the capture range of the phase lock loop. The system may be applied to a frequency synthesizer, for example in a radio receiver.

A side-loading attachment provided with sockets 41, 42 engaging the forks 38, 39 is. provided with a support 65 which is adapted to be extended laterally of the truck to rest on, for example, a storage rack 250 before a loadsupporting platform 60 is moved laterally to deposit a load on or remove a load from the rack. The support and platform are movable by hydraulic rams acting through rack and pinion mechanisms on intermediate carriages which are connected to the support and platform through pulley and cable systems. The support and platform, and the drive mechanism therefor, are pivotally mounted about an axis parallel to the longitudinal axis of the truck so as to be tiltable slightly, thereby limit switches in the truck lift circuit may be actuated. The arrangement is such that on projecting the support 65 laterally, the support tilts under gravity and actuates a limit switch. The support is then lowered until it engages the rack 250 and is thereby tilted back to the horizontal position and actuates a limit switch to prevent further lowering. The platform 60 may then be extended to receive or deposit a load on the rack, the platform being mounted on four hydraulic jacks whereby the platform may be tilted or raised and lowered slightly to facilitate depositing and raising loads in the rack. When the platform is moved laterally from its central position switches in the control circuit are actuated to prevent movement of the truck and raising of the forks. Electric and hydraulic control circuits, Figs. 24, 23 (not shown), are described in detail.
