Title: Valve lift mechanism
Inventor: WALTERS CHRISTOPHER PAULET MEL
IPC: F01L1/14
Filed: 1986-11-25
Abstract: A cam (5) on a camshaft (4) has a cam surface (5a) the outline of which, in a section plane containing the axis (4a) of the camshaft, is not parallel to that axis (4a). The camshaft can be moved lengthwise by applying oil to one side of a piston (7) which does not rotate with the camshaft. This movement is opposed by a spring (11) or by applying oil to the opposite side of the piston. The cam follower is a half- roller (16) and a body (6) which receives it in a part-cylindrical trough so that the half-roller can rotate about its axis (16a). Its flat surface engages the cam surface (5a) and the extent to which it pushes the body (6) downwardly depends upon the angle through which the cam has turned from a particular position and the extent and direction of the lengthwise movement of the camshaft from a particular position. The body (6) acts against lifting springs (3) to press downwardly a valve (1) of an engine.

Title: A capacitive apparatus for measuring liquid volume and flow rate
Inventor: GORDON RAYMOND
IPC: G01F23/26
Filed: 1988-05-18
Abstract: In a capacitive measurement of the volume of a conductive liquid, unwanted effects due capacitance Co caused by an oxide layer on an uninsulated electrode (16, figure 5) in contact with the liquid are avoided by feeding two other electrodes (12, figure 5), insulated from one another and from the liquid, with respective alternating voltages to give rise to equal and opposite currents i(1), i(2) in the electrodes (12, Figure 5). The electrodes (12) form a pair of capacitors Ci(1), Ci(2) with the liquid acting as the co-operating electrode in each case, and the capacitance Ci(1) is measured. In this arrangement, there is no current through capacitance Co and hence it does not disturb the measurement. Flow rate may be derived from volume by differentiating with respect to time. A planar dipstick (Figure 4) used for the measurement is provided with a conductive coating (22, figure 4) to eliminate the large initial change in capacitance usually seen. <IMAGE>

Title: The portable engine lifting tripod as engineers tent
Inventor: MANSER GEORGE ANTHONY
IPC: B66F19/00
Filed: 1988-08-02
Abstract: The tripod frame is brought to a vertical position, from this position the legs are moved out in an equal manner over the load of a manhole or piece of plant. As the legs open folding arms will unfold until the legs are out to the full amount, when the arms will lock them at this working position. Steel cables that are connected to the feet of the tripod will also open from their clipped position until the working full opening is reached when they will be taut or near taut. At the full opening of the legs dead locks at the tripod head will also prevent the legs from opening further. When the tripod is in position fully out and locked with the arms, a waterproof sheet may be thrown over the tripod, this is in the shape of the pyramid with a hole to allow the tripod top to come through and clips at the base to secure to the leg feet. There is an opening flap to allow access, along one of the legs this can be closed when working in the man hole. A pulley block is attached to the lifting eye, and the strops connect to the man hole cover. The cover is lifted from the ground and swung over to one side, or placed on pipes and slid well away out of the vicinity if the tent cover is not being used. The pulley is detached to give unobstructed use of the space in the tent for weather protection while working in the manhole. When the work is completed the pulley is re-connected to the eyebolt, the manhole cover swung back into position and lowered. The pulley is removed and the tent cover removed. The folding arms which are locked can be pushed up thus breaking the lock and allowing the legs to be brought to a vertical, then laid down. The cables are gathered and pushed into the special clip for store. There are several models of this tripod, some have four legs others have folding arms at the feet, others available have swing down arms, others have different methods of cable attachment. <IMAGE>
