Abstract: A dispensing system includes a container, a holder, and a signal processing module. The container includes a body configured to store a liquid and a conductive strip coupled to an outer surface of the body. The holder is configured to receive the container. The holder includes an electrical contact configured to contact the conductive strip when the container is received in the holder. The signal processing module is in electrical communication with the electrical contact. The signal processing module is configured to receive signals from the electrical contact to determine a level of liquid within the container body based on the signals when the container is received in the holder.

Abstract: The recursive profile generator of a general purpose position control system relies only upon current state and target state information in generating the path of movement for the armature of the servomotor. The profile generator employs a convergent algorithm for calculating the acceleration necessary to reach each control point or target position. By ignoring previous state information, the profile generator makes the use of reduced computing power possible and readily accommodates changing target state conditions.

Abstract: The invention provides an elastic compensation chamber, with variable volume, for a huydraulic energy dissipator of the telescopic type in which the elastic compensation chamber (20) is formed by one or more cylindrical sections (21) which only partially surround the working cylinder (1), to create large free spaces permitting an easy circulation of liquid between the said working cylinder (1) and the exterior tube (6) and in all directions, so as to accelerate the elimination of heat and avert a dangerous temperature elevation.

Abstract: An hydraulic energy dissipater with multiple working ratios, of the telescopic type, comprising a member with a variable cross-section, penetrating into a bore provided on the bottom of a piston and into a chamber provided inside the rod of the piston, which controls, as a function of its position with respect to the bore, the passage of fluid between two working chambers, either through weakly loaded valves or through more strongly loaded valves. The invention is applied more especially to the damping of yaw movements of bogies of railway rolling stock.

Abstract: Sealing device for an hydraulic energy dissipator of the telescopic type, formed by a seal comprising a cylindrical ring which grips the rod of the piston and which is extended by a fluid-tight bellows so as to permit axial movement of the seal in its housing following small amplitude movements of the rod. The device is useful for railway suspension shock absorbers.

Abstract: Apparatus for determining the rate of hair growth by measuring the length of selected hairs at various times. An illuminated transparent member is provided with a recess adapted to receive the hair longitudinally, and to maintain it in an extended condition, and is graduated to visually display the length of the hair. The body area containing the hair to be measured is located by means of a mechanism having two arms, one of which arms is adapted to be placed against a reference point on the body while the other is adjustable to indicate the desired area.
