Abstract: The invention relates to a washing machine or a washer and drier with devices for the programmed administration of liquid and/or powdery laundry treatment agents into the tub. In known laundry treatment machines, for example, there is a supply container for a specific type of laundry treatment agent, for example fabric conditioner. The laundry treatment machine according to the invention is to be so designed that the user can store different laundry treatment agents, as required, in a supply container, and that the particular required dispensing quantity of the stored agent is dispensed directly into the tub automatically at the correct point in the washing-programme sequence. The laundry treatment machine is equipped with a supply container (3) which is arranged removably behind the mounting flap of the machine and on which the type of laundry treatment agent introduced can be set by means of an adjusting device (5). Arranged inside the control panel (1) is an indicator device (11), in which the type of agent located in the supply container (3) can be displayed. The laundry treatment machine allows the automatic and programmed administration of liquid laundry treatment agents into the tub. <IMAGE>

Abstract: A snubbing unit (10), used to raise or lower a collar-­connected series of tubing joints through a riser spool (14) com­municating with a well bore, is provided with an electromagnetic sensing system (50) operative to detect and indicate the entry into, position within and travel direction within a sensing spool bet­ween the upper and lower blowout preventers (26, 28) of each tubing collar (24). The sensing system includes upper and lower electro­magnetic coils (52, 54) coaxially circumscribing the sensing spool, and a frequency generator (58) for energizing the coils. First and second phase comparators (60, 62) are used to detect current phase alterations in the coils, caused by variations in the vertical proximity between each collar (24) and the coils (52, 54), and responsively transmit output signals indicative of such phase alterations. The output signals are sent to a position sensing circuit which utilizes them to illuminate collar position and travel direction lights on an operator control panel.

Abstract: In stop logs for a shut-off device which is used in particular in hydraulic engineering, having an elongated hollow body which is rectangular in cross-section and which has a connection side provided with a groove element and, opposite said connection side, a connection side essentially parallel thereto and provided with a spring element complementary to the groove element as well as two opposite, essentially parallel wall sides which have a plane surface on the outside and end on the connection side in sealing bearing surfaces, and with sealing strips which are arranged on the sealing bearing surfaces of one connection side and of which each has a projecting head strip to which a connection-side recess is allocated in order to accommodate it, the stop logs, in order to obtain adequate tightness of the shut-off device created by placing the stop logs one on top of the other, have to be braced by means of tension bolts so than no water can escape between the plane surface of the sealing strip and the sealing bearing surface resting on this sealing strip. This complicates the assembly and dismantling of the shut-off device. A shut-off device which provides a sound seal and is easy to assemble and dismantle can be produced from stop logs in which the sealing strips (30) are arranged on the sealing bearing surfaces (26) of the connection side (20) provided with the spring element (14) and in each case have at least one sealing lip (34, 36) on the side remote from their sealing bearing surface (26), which sealing lip (34, 36) is inclined to the inside towards the spring element (14), away from the wall side (16) having a plane surface and adjoining the sealing bearing surface (26) of the said sealing lip. <IMAGE>
