Abstract: A pressure bar (13) consisting of a plate-type shaped part having at least two openings (15), extending in the same direction and extending in approximately U-shape, for accommodating at least two pairs of clips of a ring binder mechanism is designed in such a way that at least one side limb (16) in each case of the U-shaped openings (15) is constructed so as to extend obliquely in such a way that its distance from the adjacent side limb (16) is shorter at the free end of the side limb (16) than in the transition region to the base limb (17). Thus an adaptation of the pressure bar (13) to the distance, which decreases in the upper rounded transition region of the ring binder mechanisms, between the respective halves of the clip is readily possible. <IMAGE>

Filed: 1989-10-20
Abstract: The thickeners which are known and necessary for optimum applicational properties of aqueous surfactant formulations have disadvantages with respect to preparation and activity. Thus, for example, polyether esters can only be prepared under reduced pressure, elevated temperature and long reaction times. Electrolytes, for example, only have a thickening action when used in very high concentrations. The novel thickeners do not have these disadvantages. The use as thickeners of products of the reaction of a polyanhydride containing at least 2 anhydride functions with polyglycol ethers of the formula R-O(CHR1-CHR2-O)xH is proposed. These thickeners have a thickening action even when used in concentrations of from 1 to 5% and can be prepared under mild conditions. The use of products of the reaction of a polyanhydride with polyglycol ethers as thickeners in aqueous surfactant solutions.

Abstract: The circuit described for adapting the bit rates of two signals is needed, for example, in plesiochronous multiplexers in order to bring the plesiochronous signals, which are to be combined to form a digital signal at the next hierarchy level, to the same bit rate. For this purpose, the circuit arrangement contains an elastic memory (4) and a stuffing decision circuit (15, 16). For a circuit arrangement having such features to be usable for bit rates of the order of magnitude of 140 Mbit/s and still to be constructed mainly in CMOS technology, means (11, 14) are provided by means of which the bit clock of the first and of the second signal is scaled down at a ratio of 1:n. Furthermore, a series/parallel converter (2) converts bit groups of n serial bits of the first signal into bit groups of in each case n parallel bits which are loaded in groups into the elastic memory (4) and are similarly read out of it again. The parallel bit groups read out are supplied to a controllable selection matrix (5) having n outputs which contains means by means of which n selected bits from more than one bit group are transferred to the n outputs. The stuffing decision circuit (15, 16) controls the read-out process from the elastic memory (4) and the selection matrix (5) in dependence on its decisions. <IMAGE>

Abstract: A multiline check valve assembly (10) has an elongated body which defines a fluid passageway (44) and which is formed with a plurality of valve cavities (42a,42b,42c) that are in fluid communication with the fluid passageway. Each valve cavity has a resilient valve element (78a,78b,78c) disposed within the cavity and each valve element rests in the cavity with one end against a protrusion (46) disposed in the cavity for centering the element within the cavity. The resilient valve element is biased to urge its other end against a valve seat (96) that surrounds an opening to the valve cavity to create a fluid tight seal with the valve seat and close the opening. In addition, and access port is formed circumferentially around both the valve seat and opening to establish a fluid communication path through the access port to the fluid passageway in the body when the valve element is separated from the valve seat. Specifically, when an appropriate fluid line connector (28,30,32) is inserted into the access port to urge against the resilient valve element, the valve element is deformed away from the valve seat to complete the fluid communication path between the access port and the fluid passageway.
