Title: Improvements in or relating to the registering mechanism of water and other flow meters
IPC: G01F15/07
Filed: 1939-03-08
Abstract: 526,074. Registering-mechanism. LEA RECORDER CO., Ltd., and HORNER, J. W. March 8, 1939, No. 7473. [Class 106 (iv)] A water or other flow meter with a compound range of measurement has a single rotary integrator disc adapted to be engaged by a plurality of counter-operating wheels movable across the disc so that the pick up of the wheels is proportional to the variable to be measured and engaged with or disengaged from the disc in sequence so as thereby to produce a change of range of measurement. In the form shown in Figs. 1 and 3, a disc 11 driven by a clockwork or synchronous electric motor 12, has arranged in front thereof two contact wheels 17, 18, driving counter units 15, 16, mounted in brackets attached to a slidable bar 14 that carries a follower 19 arranged to engage a helical groove in a drum 20. The parts 21, 22 of the helix have different ranges and the drum is arranged to be rotated by a float-operated chain 25. The axis of the. drum drives, through a reduction gearing 28, a drum 29 with a scale of depth or rate of flow read against a pointer 30. A lug 23 on the bar 14 may carry a pen to mark a chart. The contact wheel 17 is held out of contact with the disc 11 by a trip bracket 34 until it reaches the centre of the disc. Other ways of holding one counter wheel inoperative during the first part of the traverse are described. Specification 298,711, [Class 106 (iv)], is referred to.

Title: Centre hoisting device
IPC: B66C1/44
Filed: 1973-02-15
Abstract: 1365656 Lifting devices FINNLINES Ltd OY 15 Feb 1973 [17 Feb 1972] 7480/73 Heading B8H A roll 14 having a centre hole 13 is raised by means of a centre hoisting device comprising a liquid containing cylinder 6 in which a piston 9 is movable by means of a piston-rod 2 having a loop 10 for engagement with a hoist (not shown), the cylinder 6 having openings 5 which communicate with the space formed between the cylinder 6 and an outer resilient wall 1, such that in use, when the device is inserted into the centre hole 13 the device is initially held down and the piston-rod 2 and piston 9 are raised, thus forcing the liquid in the cylinder 6 through the openings 5 to increase the volume of the said space thus forcing the resilient wall 1 into frictional engagement with the surface of the centre hole 13. Hoisting can then take place, and at the end of the hoisting operation a return spring 3 urges the piston 9 back to its original position. A collar 7 prevents the piston 9 from blocking the openings 5 when the piston 9 is in its uppermost position.
