Abstract: The invention relates to a unitary spine binder for securing a stack of sheets, which comprises a dorsal part (3, 4, 5) from which spaced fingers (1, 11) extend to form loops. The individual fingers are arranged in two sections (1, 11) lying opposite one another on this dorsal part (3, 4), the dorsal part (3, 4, 5) forming a hinge between the finger sections (1, 11). The end (12) of at least one of the first finger elements (1) remote from its dorsal part is equipped with a push button (7); the end (22) of the second finger element (11) remote from its dorsal part and lying opposite the first finger element is equipped with an opening (10) essentially complementary to the push button (7), and which is adapted to receive the push button (7). In this way, a simple spine binder is created which does not require the use of additional binding devices. Sheets can be removed from the spine binder or newly inserted into it.

Abstract: A process for the preparation of alkylphenols of the formula I ##STR1## in which R.sup.1, R.sup.2, R.sup.3, R.sup.4, and R.sup.5 stand for hydrogen or C.sub.1 -C.sub.8 alkyl, by reaction of an alkylcyclohex-2-en-1-one of the formula II ##STR2## in which R.sup.1, R.sup.2, R.sup.3, R.sup.4, and R.sup.5 have the aforementioned meanings, at temperatures of from 200.degree. to 400.degree. C. and pressures ranging from 0.01 to 50 bar in the presence of palladium-on-.alpha.-Al.sub.2 O.sub.3 catalysts, wherein the catalyst used has a specific surface area (BET) of from 1 to 10 m.sup.2 /g, a pore diameter of from 5 nm to 300 .mu.m and a pore volume of from 0.1 to 0.5 cm.sup.3 /g, from 80 to 100% of the pores having a diameter of from 40 to 400 nm, and also novel palladium-on-.alpha.-Al.sub.2 O.sub.3 catalysts as obtained from a fine-grained alumina powder by steps of molding, pyrolysis and calcination.

Abstract: A hemodialysis apparatus is supplied with dialysis fluid or a dialysis fluid component through a supply loop conduit 12. A shut-off device 22, such as a magnetic valve, is arranged between the apparatus and the supply conduit 12. A buffer volume is enclosed between the shut-off device and an additionally arranged shut-off device such as a non-return valve. During disinfection of the apparatus, in order to prevent disinfecting fluid from flowing back into the supply loop conduit and therewith an endangering other dialysis apparatus connected to the same supply loop conduit, in the event that the shut-off device 22 leaks, the buffer volume is pressurized to a defined pressure, which is preferably higher than the pressure in the surrounding conduit sections. This pressure is detected by a pressure sensor P. The signal generated by the pressure sensor P is monitored by a microprocessor 28.

Abstract: Unused towel rolled up in a shell (4) is guided between a roller (38) and a tracer (40) for detecting the towel end and via a transport roller (6a), forms a loop and runs via a transport roller (6b) to a roller (13) guided in slots (14a,b) and intended for receiving used towel. To ascertain whether the loop is being used or not, there is a movement sensor (20) with a bar (22) which is suspended rotatably about a horizontal axis and to which is attached a batten (23) via which the towel (5) is guided. Clamped in the bar (22) is the upper end of a piezoelectric element which at its lower end is clamped between parts connected to a sensor housing (21). Since a distinction can be made between use and non-use, it is possible for released unused towel to be retracted again. Various programs can be selected for operating the towel dispenser, and in particular the loop can be formed from unused and used towel or only from unused towel.

Abstract: A room spray dispenser includes an adjustable triggering lever having a roller to engage a moving object, such as a door, to activate the spray. Rotation of the lever in a first direction causes a trigger/rocker element to be placed in a cocked position in which actuating springs are tensioned, which subsequent rotation of the lever causes the trigger to return to a rest position, the spring energy being directed to actuate a spray valve. A following rotation of the lever in the first direction reloads the mechanism for the next spray.

Abstract: A tensioning device for hubs, comprising a winding shaft having rotatably and drivably mounted on it individual winding elements as hub holder for hubs with inner cylindrical bores, the tensioning device including measures for locking the hubs in the axial direction on each individual winding element, wherein the hub (1) includes along its inner circumference (3), alongside the inner bore (5) and uniformly distributed over the circumference, a multiplicity of resilient elements (2), which have the form of a bent-off arm which extends in the radial direction from the inner circumference (3) of the hub (1) and is bent off in the circumferential direction, the end (4) of each resilient arm being at a distance from the bending point of the next-following arm.

Abstract: In a towel dispenser, a selection can be made between a standard program, in which, to form a towel loop, first a portion of unused towel and subsequently a shorter portion of used towel is released, and a hygiene program, in which only unused towel is released. In both cases, a movement sensor monitors whether the towel is moved as a result of external action, and if this is so the towel portion is drawn in as used 3 seconds after the movement has ceased. If the towel, after being dispensed, is not moved for 20 seconds, it is retracted as unused. In both cases, economy programs with a dispensing of shorter towel portions can be selected. Within the standard program, a selection can be made between a normal program, in which used towel is first drawn in and subsequently unused towel is provided, and a fast program, in which the dispensing of unused towel takes place first.

Abstract: A device for directing individually supplied sheets onto a sheet depositing surface includes a feeder for feeding sheets along a sheet path onto the surface and a pivotably mounted sheet directing element that includes a first arm which extends across the sheet path. The pivotable directing element includes a weight mounted thereto above its pivot axis for increasing the moment of inertia of the pivotable directing element.

Abstract: The invention relates to a demagnetizing device for magnetic recording media, so-called pancakes, wound up in the form of a tape, which device consists of a cylindrical coil (1), the field distribution (3) of which extends essentially parallel to the winding plane (2) of the recording medium (4), while the pancakes (4) can be inserted into the coil (1) in the axial direction by a lifting device (5). The compact form enables an entire pancake stack to be demagnetized at the same time (FIGURE).

Abstract: The cloth towel dispenser appropriately comprises two towel units, whereof each unit is independently completely operational. The cloth towel (7) is guided over a delivery roller (20) into a draw-in roller (25). On pulling out the towel (7) for forming a towel loop (8), the delivery roller (20) is also rotated, as is the draw-in roller (25) via an envelope drive (32). In the draw-in shaft (30) is located a spring tension accumulator (36), which is tensioned on pulling out. By means of a cam wheel (43) and a catch (44), the length of the towel which can be pulled out is limited. As also a part of the used towel wound from the draw-in roller (25) can be retracted, the length of the clean towel to be pulled out can be kept smaller. After a certain interval a timer releases the catch (44), so that the spring tension accumulator rotates the draw-in roller (25) and the cloth loop (8) is wound up.
