Abstract: A rechargeable storage battery power supply system in which a coulometer is used as a logic device to provide transition between high charge rate and low charge rate. During battery discharge, the coulometer may act as a logic device to disconnect the load from the battery after a predetermined time integral of current is drawn from the battery. The charging current is applied in reverse direction through the coulometer and when the coulometer reaches its high impedance state in the charging direction a trickle charge is bypassed to the battery. The trickle charge control includes a thermistor responsive to battery temperature. An additional circuit is provided which acts to provide constant voltage float charge after the battery has been fully charged, and which additional circuit also uses the coulometer as a logic element.

Abstract: A new and improved method of designing an ophthalmic lens series and a new and improved ophthalmic lens series. The method takes into consideration numerous factors affecting lens performance and by means of systematic calculations and graphical analysis provides the lens designer with a means for determining, for any given prescriptive power, the lens shape which will provide optimum visual acuity at angles of viewing up to 40* from the optical axis of the lens, simultaneously giving consideration to tangential and sagittal power errors, errors of astigmatism, variations in stop distance, ability of the eye to accommodate for certain errors, lens thickness, visual tasks of the wearer determined by statistical techniques, and many other factors. The lens series may cover the entire range of ophthalmic prescriptions and provides lenses having increased visual acuity over the whole area of the lens including angles of view up to 40* from the optical axis of the lens. A comparatively small number of groups of lenses are used, each group having one base curve identical for all lenses of the group.

Abstract: A valve slidably disposed within a bore and movable between first and second positions to control application of a source of fluid under pressure between an inlet and outlet port. An electrically operated torque motor is connected to the valve to drive the valve in response to an electrical signal applied to the torque motor. The valve is connected to a system and is responsive to a discrepancy between a control and monitor section of the system to effectively lock the system in a failure indicating mode of operation.

Abstract: A hand-held power tool comprises an internal combustion engine on which a power tool is mounted and by which it is driven. The engine is mounted by vibration isolators on an essentially rigid supporting structure comprising a base portion, a front handle and a rear handle. Four vibration isolators are so arranged as to isolate the supporting structure from vibration of the engine while providing effective control of the tool by an operator holding the supporting structure by the front and rear handles. The vibration isolators are shown in the form of hollow barrelshaped bodies of elastomeric material.

Abstract: A suspension system for a tracked vehicle is shown, having a unitary suspension frame including a pair of relatively flexible slide rails for engagement with the lower run of the drive track. Idler means mounted on the rear end of the frame support the rear end of the track. Front and rear pairs of sloping support arms are pivotally connected to the body at their upper ends and are connected to the frame at their lower ends by pivotable link members that accommodate limited relative longitudinal movements between the frame and the body. Front and rear suspension spring means are mounted between the body and the frame. Rearwardly and downwardly sloping control arm means are pivotally connected between the body and the front end portion of the frame so that the pivotal movements thereof force the frame away from the body when the frame moves forwardly with respect to the body, thereby forcing the drive track into tighter engagement with the ground. The front pair of support arms limits the pivotal movements of the control arm means.
