Title: Link-type rotary coupling
Inventor: SCHMIDT WARREN EDWARD
IPC: F16D3/16
Filed: 1988-01-20
Abstract: This invention relates to rotary couplings (4,11) for transmitting torque between rotatable drive (61,12) and driven means (3,13). The couplings (4,11) include links (5,25) which each including an axially stiff body (25c) connected at respective ends to the drive and driven means by respective elastomeric bearings (35,36), which allow pivoting of the body about respective axes which are parallel. At least one of the bearings (35,36) also allows further pivotal movement of the body (25c) about a third axis which is orthogonal to one of the other axes. This elastomeric bearing (35) is so formed as to accommodate the link motion necessary to effect a substantially constant velocity connection between the rotatable members (4,11;3,13).

Abstract: A belt tensioner (38) comprising a pivoted structure (62) carrying a pulley (78) for rotation about a rotational axis and mounted on a fixed structure (44) for pivotal movement between an increased range of angular movement. The pulley (78) is operatively positioned with respect to its rotational axis and the pivotal axis of the pivoted structure (62) such that the lever arm to the pivotal axis through which the generally constant belt load force acts on the pivoted structure (62) increases at a decreasing rate and then decreases at an increasing rate throughout the range of movement of the pulley between its first and second positions in a direction toward the second position. The spring assembly is operatively associated with the pivoted structure so as to apply a spring torque to the pivoted structure which increases at a decreasing rate and then decreases at an increasing rate throughout the range of movement of the pulley between its first and second positions in a direction toward said second position.

Abstract: An improved steam inhaler (1) for producing steam from water (W) and aspirating inhalation liquid (F) having a certain medical efficacy with the steam, comprising: a water supply tank (8), a first conduit (9), a first heating chamber (12), a second conduit (16), a second heating chamber (13), and a steam nozzle (17), along the path the water conveyed. The first and second heating chambers (12,13) are provided with heating elements (4), and a one-way valve (10) is provided in the first conduit (9). Therefore, the water boiled in the first chamber (12) is conducted into the second heating chamber (13) and prevented from returning to the water tank by the one-way valve (10). The water is completely vaporized in the second heating chamber (13). Since the water is thus metered from the water tank into the first heating chamber substantially upon demand, the steam inhaler can be activated immediately after the power is turned on, and can be deactivated immediately after the power is turned off. Thereby, the convenience of the steam inhaler is improved, and the waste of the inhalation liquid may be prevented.

Abstract: The invention is directed to a papermaking machine in which the wet paper web is supported by the press section felt as it is transferred from the press section to the dryer section of the machine, thereby preventing sagging and possible breakage of the web. According to the invention, the felt is mounted for endless travel and passing around at least a first of said dryer rolls, said felt being unsupported over a substantial distance extending between said press rolls and said first dryer roll and said web being carried on the upper surface of the felt as said felt travels through said distance. 
     As the wet paper web is supported in the draw, sagging and possible breaking of the web is prevented in this area. As thee tendency for breakage is minimized, product loss is minimized and downtime of the machine is correspondingly decreased.

Abstract: Electrical pushbutton switch, particularly for the step-by-step actuation of window lifting motors in motor vehicles. Known two-step pushbutton switches are equipped with two snap springs arranged above one another which are activated in steps after one another by means of a single rigid switching plunger. The low number of switching positions, the production disadvantages occurring because of the production tolerances to be maintained and the design-related low rating with respect to switching performance and life are disadvantageous. According to the invention, it is proposed to implement a multi-pole step pushbutton by the fact that the step pushbutton is constructed as a rocking button by means of an operating rocker (5). Furthermore, at least one switching plunger (9) with variable length due to actuating forces acting with different strength is also provided in addition to a rigid switching plunger (8), in which variable-length switching plunger a compression-spring-loaded sliding member (7) is displaceably arranged. The switching plungers (8, 9) are formed next to one another on one rocker arm (A, A') in each case and load, proceeding step by step away from the pivoting axis (16), snap springs (SFn, SFn') located underneath plunger points (Sn, Sn'), which springs are arranged flat on a conductor panel (3), the spring constants (Dc, Dn-1) of the snap springs (SFn, SFn') and of the compression springs (DFn-1, DFn-1') being dimensioned in accordance with Dn-1 > Dn-2 > ... > D2 > D1 > D0. This creates a multi-pole rocker step button of flat construction which offers production advantages particularly in automated production. <IMAGE>

Abstract: In an electric switching device (1), particularly constructed as a temperature regulator, the resilient switching arm (14) controlled by a hydraulic expansion cell (12) for operating a snap switch (5) is fixed by means of positively engaging snap connections (32) to plate-like support parts (20) of a sheet metal support body (3) of a body (2), the support parts (20) on either side of the switching arm (14) being at right angles to joint axis (25) of arm (14) as lateral bends to a base plate (30) of support body (3) and receive between them an end portion of an insulator (4) carrying the switch (5). This leads to an extremely favourable taking up of forces, so that the support body (3) can be made from extremely thin sheet metal as a relatively elastic component. It also leads to a very simple assembly of the switching arm (14).

Abstract: Chromatography apparatus which is capable of deriving optimum conditions for an analysis includes data processing means which comprises calculating means (20) which is supplied with initial conditions (24) which may be entered by the chromatographer and which may be calculated from the results of an initial chromatogram, limits and requirements (25) which relate limiting values of parameters of the chromatograph and to the required selectivity and sensitivity of the analysis and which are entered by the chromatographer, and the detector time constant (23) which is selectable, within limits, by the chromatographer. The data processing means also includes a column data base (21) which contains data specifying the available separating columns and a detector data base (22) which contains data specifying the available detectors. 
     The optimisation criteria are the minimum possible analysis time coupled with adequate peak separation and sensitivity. The optimum conditions are obtained by calculating maximum mobile phase flow rates which produce the required peak separation and sensitivity with each available separating column, detector, time constant combination and selecting that combination which allows the fastest analysis (26). The conditions may either be automatically set up or indicated to the chromatographer by means of a display unit or a hard copy may be produced by a printer.
