The fire hose passed through the washing portion is pulled out by the first and second fire hose feed­ing devices. A plurality of sensors (74, 75) for detecting metal connectors (84, 86) of the fire hose are provided at different positions on the fire hose feeding path so that upon detection of a metal connector by one sensor, the fire hose is pulled out by the second fire hose feeding device while stop­ping the hose feeding by the first fire hose feeding device. Upon detection of a metal connector by another sensor, the fire hose is pulled out by the first fire hose feeding device while stopping the hose feeding by the second fire hose feed­ing device. Thus, the first and second fire hose feeding devices are alternatively and alternately operated upon detec­tion of a metal connector so that the hose is cleaned contin­uously regardless of existence of the metal connectors.

Abstract: A reference cell for evaluating the turbidity of liquids, in particular of emulsions. In evaluating whether the oil content of an oil-containing liquid to be purified is still below a permissible value, a comparison is made with a reference liquid in a cell. Said reference liquid, which is generally also an oil-water mixture, demulsifies with time, resulting in uncertainties in the assessment. In the new reference cell, at least one transparent hollow cylinder has a predetermined light scattering power corresponding to a predetermined turbidity value. Errors due to a decomposing liquid can no longer occur. Evaluation of clarified oil-water mixtures. <IMAGE>

Abstract: In ripple-control transmitting installations, which consist of a ripple-control centre and a plurality of decentralised substations, each substation containing a ripple-control transmitter which supplies a ripple-control message into a current supply network, it is intended that the ripple-control message be supplied synchronously by the individual transmitters. The invention proposes a method for transmitting a data message from the ripple-control centre to the substations and for synchronised generation of a ripple-control message in the substations which corresponds to the data message. In this method, the data message is transmitted in the multi-point traffic from the ripple-control centre to the substations, acknowledgement of receipt of the data message is asked for and, if necessary, the data message is transmitted repeatedly. In the substations, receipt of a data message initiates the start of a delay period after which the ripple-control message is transmitted provided no countermand message, transmitted by the ripple-control centre, occurs before the delay period has elapsed. <IMAGE>

Abstract: An optical storage disk reading apparatus (10) allows the simultaneous reading of both sides of an optical storage disk (44). An upper base plate (12) and a lower base plate (14) pivot about hinges (22-28) through the action of lead screws (30-32). The lead screws (30-32) are turned by separate stepper motors (38-39) which drive follower nuts (34-36) therealong. The follower nuts (34-36) are interconnected to the baseplates (12-14) by yokes (40-42). As the lead screws (30-32) drive the follower nuts (34-36), the yokes (40-­42) pivotally move the base plates (12-14) about the hinges (22-28). A cartridge (46) containing the storage disk (44) is loaded into the apparatus (10) along receiving channels (48-50). The channels (48-50) hold the cartridge (46) from movement while the disk (44) is free to move therein with the lower base plate (14) through an interconnecting drive spindle (20). The disk (44) is thus positioned parallel to and a fixed distance from the lower base plate (14) equal to the focal distance of an optical reader (54) thereon. The upper base plate (12) is positioned parallel to the lower base plate (14) and a variable distance from the disk (44). An optical reader (52) on the upper base plate (12) provides data to the stepper motor (38) associated therewith to move the upper plate (12) to the proper focal distance from the optical reader (52). When the upper plate (12) moves, the lower plate (14) also moves to keep a parallel relationship therebetween.

In a preferred embodiment, the second control pressure is supplied from a braking line of the towing vehicle, such that the "back up" control pressure is a function of the towing vehicle braking.
