Abstract: A Folding shopping trolley [1] having an upper section [11] and a base section [2] adapted to move between a collapsed condition into a deployed condition is disclosed. The upper section [11] connects to the base section [2] via elongate support members [20] through an intermediate coupling [10] such that the upper section [11] and base section [2] can move in a synchronized condition between deployed and collapsed conditions. The base section [2] comprises ground engaging wheels [47 and 48] fixed to the lower end of the elongate support member [20]. The lower end of the elongate support members [20] are pivotly connected to the lower end [9] of the actuator [7] via the inner connecting members [6] forming a geometric arrangement with the outer connecting members [5] wherein vertical movement of the actuator [7] moves the trolley from the collapsed condition to the deployed condition. The outer connecting members [5] include a locking mechanism [30] to lock the trolley [1] in the deployed position. The actuator is free to move within a sleeve [14] which is fixed to the coupling [10]. The outer connecting members [5] and the inner connecting members [6] support a fabric tray [35]. The upper section contains handles [21] and corner bag supports [25]. The four triangular shopping bags [23] are provided with stiffening elements [24] the ends of which engage with corner supports [25]. The upper inner edge [45] of the bag [23] is provided with a cutout [46] which engages with the hook [40]. The shopping bags [23] are removable from the corner supports [25] and the center hook [40] by grasping the strap [44] and the stiffening device [24] at the cutout [26].

Abstract: A number of variations are provided of a device that provides an amplified single polarization optical signal. Each of these relies on the use of a non-polarization maintaining gain medium through which the signal is directed, and a polarization shifter and reflector that direct the signal back through the same gain medium with a shifted polarization state. An input polarization beamsplitter directs the returning optical signal away to an output, based on its shifted polarization state. The embodiments of the invention include the use of double-clad fiber. Multiple stages may be used to provide specific amplification parameters. In one embodiment, both amplification stages reside in the same polarization shifting optical path. A polarization maintaining amplifier of this type may be used as part of a master oscillator-power amplifier, in which polarization maintaining fiber is used as part of the source laser. Wavelength selective components are also used in certain embodiments of the invention, to allow for wavelength selectivity, as well as a single polarization state, in amplifiers, lasers and amplified spontaneous emission (ASE). In one embodiment, an optical circulator is used to allow the amplified, shifted polarization state signals to be directed away from the input to a desired output port. A feedback loop may also be used to control the polarization state at the amplifier output. A polarization beamsplitter at the output directs light not having the desired polarization state to a photodetector, the output of which is used by a polarization controller at the input, such that the input polarization state is adjusted until the control signal from the photodetector is minimized.
