Abstract: A B S T R A C T         This invention consists of a vehicle for handling multi-furrow ploughs, which are very heavy and are equipped with only one wheel in the rear, when not attached to a tractor during operation.  It consists of a two wheeled cart provided with two hooks attached to the main body of the cart, by means of which the front end of the plough is picked up and held, and a central arm for pulling the cart which is swivably attached to the main body.  A ratchet operated cylinder having two op-positely threaded screws, one going in or out at each end simultaneously, is swivably attached to the arm and to the main body of the cart, so that turning the ratchet in one direction expands the distance between the screw ends thus lowering the hook towards the ground to pick up the front end of the plough, and turning it in the opposite direction re-duces that distance and lifts the hooks and front end of the plough to make it mobile. A variation of the above invention shows the hooks being attached to a pair of hydraulic jacks, thereby eliminating the need for the said ratchet operated cyl-inder, and the swivel attachment of said central arm.

Abstract: ABSTRACT OF THE DISCLOSURE         A model railway or road vehicle installation, in which vehicle mounted electric drive motors are supplied through contact with track cond-uctors, has a power supply providing an intrinsically safe a.c. component of such frequency and amplitude as to be capable of breaking down any contact inhibiting dielectric layer of dust, grease, metal oxide etc on the track conductors, in addition to the normal d.c. component powering the vehicle.          An automatic arrangement suppresses the a.c. component so long as good electrical contact is maintained so that the a.c. component is provided only when necessary.  For facilitating slow speed operation, the d.c. supply is pulsed with a variable mark to space ratio dependent upon the desired vehicle speed thereby to maintain the torque output of the vechicle motor.

Abstract: ABSTRACT OF THE DISCLOSURE          An adjustable recliner chair of the type in which the chair back is pivoted at an intermediate point to a supporting frame and the chair seat is pivotally supported at its rear by the chair back so that as the chair back is tilted rearwardly, the chair seat moves forwardly, the chair seat having adjacent its front an inclined cam surface which slidably engages a support member secured to said supporting frame so that as the chair seat moves forwardly the front of it moves upwardly.  The support member and inclined cam surface are held together by an adjustable friction connection which is adjusted to vary the frictional effect tending to hold the chair seat in any adjusted position. The supporting frame may be mounted on a base through coil springs which enable the chair to be rocked.  The adjustable friction con-nection, in such case, is adjusted to ensure that the frictional effect is sufficient to maintain the chair seat and chair back in their adjusted position as the coil springs are flexed during the rocking operation.  The chair may also have a swivel connection between the supporting frame and base to enable the chair to be swivelled.
