Abstract: An apparatus for assessing a position of an anchorage of a child restraint anchorage system. The apparatus includes a frame, an engagement arm, and a latch pin. The engagement arm is adapted to receive the anchorage and is disposed proximate the frame. The latch pin is disposed at least partially within the engagement arm and is adapted to rotate to secure the engagement arm to the anchorage.

Abstract: The bracket includes an upwardly opening U-shaped element which, in use, is adapted to receive a rung of a ladder for maintaining the ladder upright. The bracket includes a plate which is attached to the U-shaped element and has a number of parallel slits spatial apart from one another. Each slit is oriented upwardly at an oblique angle and receives a nail for fastening the bracket to a wall or roof.

Abstract: An apparatus for assessing visibility of an anchorage disposed proximate a vehicle seat. The apparatus includes a mounting assembly adapted to engage a first anchorage and a laser adapted to project a beam toward a second anchorage. The mounting assembly is pivotable about the first anchorage to adjust an angle at which the beam is projected toward the second anchorage.

Abstract: A tool for measuring force associated with engaging an anchorage of a child restraint anchorage system of a motor vehicle. The tool includes a force measuring device, an engagement arm having a slot, and a guide mechanism. The engagement arm transmits force to the measuring device when the anchorage is seated within the slot.

Abstract: A trailer having an endless conveyor is provided. The trailer comprises a support frame, and a load supporting floor having opposed first and second ends, the floor being disposed above the support frame. A pair of opposed sidewalls extend upwardly from lateral sides of the floor. A first roller positioned towards the first end of the floor and a second roller positioned towards the second end of the floor. An endless belt extends about the floor and the first and second rollers such that an upper portion of the belt passes over the floor and a lower portion of the belt extends below the floor. The belt has sufficient elasticity to frictionally engage the first and second rollers. A drive mechanism is coupled to the first roller for rotating the first roller and causing travel of the belt. A tensioning mechanism for maintaining a relatively constant belt tension during travel of the belt is also provided.

Abstract: A tool for assessing the position of an indicator mark disposed on a seat of a vehicle. The tool includes an arm adapted to contact an anchorage and a plurality of lasers adapted to project a set of beams toward the seat. The set of beams define an area indicative of a desired location of the indicator mark.

Abstract: The steering of a motor vehicle is assisted by a power steering means including a hydraulic distributor which is supplied with pressurized fluid by a pump from a reservoir. The vehicle also has a clutch having hydraulic servo assistance supplied by a servo unit. The distributor of the power steering system and the clutch servo unit are both supplied with hydraulic fluid from the same pump and reservoir, through a distribution unit which is so arranged that the power steering system has first call at all times on the available pressurized fluid. The distributor unit includes a flow distributing valve, fed from the pump and dividing the flow between a main circuit which leads to the steering distributor, and a secondary circuit which leads to the servo unit. A pressure regulating valve is connected to both the main circuit and the secondary circuit so as to regulate the pressure in each of these circuits according to the demand of the power steering system.

Abstract: An actuator for a friction clutch having a diaphragm includes coupling means comprising a first part associated with the clutch actuating linkage, and a second part associated with the actuator proper. The actuator, of the fluid operated type, comprises a main piston working in a main cylinder and defining with it a control chamber. A secondary piston works within the hollow bore of the main piston to define within the latter a wear compensating chamber. The main piston carries a shut-off valve for bringing the control chamber and the wear compensation chamber into communication with each other when the clutch is in its engaged position. The actuator also includes a booster spring for applying additional force to the diaphragm, such that the characteristic of the diaphragm has a positive gradient over the whole travel between the engaged and disengaged positions of the clutch.

Abstract: A servo control device for a torque coupling device comprises a driving member actuated by an electric motor, and a driven member driven by the driving member and coaxial with it. The electric motor is mounted on a fixed support in a position offset from the axis of the servo device and is coupled through a mechanical connection to the driving member, with the driven member being coupled to the driving member through connecting rods, each of which is pivoted on both the driving member and the driven member. The invention is applicable to automotive use.

Abstract: Hydropneumatic system for recovering braking energy for a vehicle comprising a power "shunt" transmission, characterized in that it comprises two hydraulic switches (19 and 20) or equivalent devices, the first of which permits two hydraulic machines or sets of machines (3a, 4a) to be combined or opposed and the second of which (20) enables the two-direction lines joining these machines to the hydropneumatic accumulator (17) and a low-pressure reservoir (18) to be connected straight through or crossed-over.Their operation enables the cylinder capacities of the machines to be controlled so as to store or restore the deceleration energy.

Abstract: Hydropneumatic energy reservoir for accumulating the braking energy recovered on a vehicle by means of a hydrostatic energy recovery-restoration device, combined or not with the vehicle transmission and working between a high-pressure accumulator and a low-pressure accumulator, characterized in that it comprises several oblong cylindrical hydropneumatic accumulators (1) connected hydraulically in parallel and placed side by side inside a single casing (6) of small height, the space included between the said casing (6) and the said accumulators (1) forming the low-pressure accumulator (16).

Abstract: A continuous process for recovery of metals, especially precious metals, from various ores, involves pulverizing the ore to a particle size less than five microns, forming a colloidal suspension of the particles in a liquid, extracting metal from the slurry with a solvent, and separating the solvent from the particles centrifugally. Metals are recovered from the liquid solvent, which is recycled. Contacting of the slurry with fresh solvent is preferably effected in a staged counter-current centrifugal extraction unit.

Abstract: A method is disclosed for the manufacture of phosphoric acid directly from phosphate rock wherein the crushed phosphate rock is mixed with dilute phosphoric acid to form a slurry and the slurry is then heated to produce calcium monophosphate. Thereafter, oxalic acid is added to the slurry to precipitate the calcium therein as calcium oxalate which is separated. The liquid resulting therefrom which contains the phosphoric acid from the rock is then treated conventionally to recover the phosphoric acid therein.

Abstract: In a vehicle guidance system, a circular-section guidance rail is embraced y a detector on a vehicle. At a fork, where the rail progressively broadens prior to dividing, the rail height is reduced so that a detector, when tilted to select one branch of the fork, has its lowered side between the rail and a side wall of a channel in which the rail is mounted and its raised side riding over the broadened rail.
