Abstract: The invention relates to an arrangement in a vacuum system for waste water and the like. In such arrangements it is a problem to convey the waste water in a simple and reliable manner from the sanitary installations into the pipeline system, in which vacuum prevails, for being further conveyed to a collecting place. The arrangement according to the invention comprises a vertically movable container (10) in which the waste water is collected. By causing the weight of the liquid to surmount a spring force and a force originating from the vacuum in the pipeline system, an outlet for the water is opened, which is thus discharged into the pipeline system.

Abstract: An optical scanning system (100) in which a collimated light beam (118, 120), e.g. a laser beam, is swept periodically across a target surface, e.g. a rotating photoconducting drum (132), includes beam synchronization feedback (140, 142, 144, 146, 150, 152). A portion (118) of the light beam is split off and swept across an array of apertures held in place by a fibre optic assembly (140). The light entering the fibre optic apertures is transmitted to one or more photodetectors (146) which generate corresponding electrical signals thereby to sample the tangential velocity of the sweeping beam (118, 120), which are applied to a variable frequency oscillator (150) whose output synchronizes modulation of the beam. 
     The described variable frequency oscillator is a phase locked loop connected to the photodetectors (146), and includes a fast synchronization circuit which provides immediate synchronization between the character clock signal and the first electrical signal of each new sweep. In addition, a hold circuit is provided which holds the frequency of the character clock signal, coming from the phase locked loop constant during the dead time between beam sweeps.
