Abstract: An apparatus for testing passive two terminal devices in the VHF range comprises an electrical signal generator whose frequency is variable over the VHF range, a distributed constant line having a first end connected to the generator and a second end connected to the device to be tested. A resistive  pi  network is connected to the first end of the line to measure directly the values of the incident wave and of the reflected wave or the maxima and the minima of the total wave at the first end of the line are detected, so as to determine the coefficient of reflection of the line connected to the device to be tested.

Abstract: Handling for the user of nipper pliers with two handle legs (11, 12), each with a jaw (14, 15), which are connected operatively by means of a joint (13) is optimised and improved by an ergonomic design of the handle legs (11, 12). This is achieved in that the handle legs (11, 12) are opposite one another elliptically at the lower end, in that the handle legs (11, 12) are elliptical along the coupling faces with the hand and with the fingers, and in that the handle legs (11, 12) have an elliptical cross-section in the region of the coupling face with the hand. The advantage of this design of the hand side of the nipper pliers is that, for all uses, the handle legs (11, 12) are as closely matched as possible to the anatomy and anthropometry of the human hand. <IMAGE>

Abstract: A diaphragm-type valve uses a multiple annular metal diaphragm (36) welded about its inner periphery to a valve operating stem (34). The diaphragm is sealingly clamped about its outer periphery to the valve body and is also clamped about its inner periphery at a location spaced outwardly of the weld to prevent the weld from being subjected to flexure stresses during valve actuation. The outer periphery of the diaphragm (36 min ) may be welded to the valve body (10 min ) outwardly of the outer clamp. The actuating assembly (20) is arranged to produce non-rotary, reciprocatory movement of the operating stem (34) through a bonnet mounted rotary actuator (116). A stem tip seal (16) comprises a metallic seal ring (152) backed by a PTFE ring (158) and surrounded by a harder plastics ring (160) held captive by a sleeve (166).

Abstract: A method is provided of producing a self-supporting ceramic composite structure having one or more encasement members (14), such as an encasing stell sleeve, joined to it by growth of the ceramic material to engagement surface(s) of the encasement member(s) (14). A parent metal is contacted with a body of filler (38) which is encased by the encasement mmber(s) (14). The resulting assembly is heated to melt and oxidize the parent metal, e.g., aluminum, to form a polycrystalline material comprising an oxidation reaction product which grows through the body of filler (38) and stops at the engagement surface(s) of the encasement member(s) (14) which thereby determines the surface geometry of the grown ceramic matrix. Upon cooling, the encasement member(s) (14) is shrinkfitted about the ceramic composite body. The invention also provides the resultant articles, for example, a ceramic composite body having a stainless steel member affixed thereto.

Abstract: In order to provide support for the foot and prevent premature fatigue caused by a cramped position of the foot and leg, foot rests are known on which the driver of a vehicle with automatically regulated speed can rest his right foot, removed from the accelerator pedal, and which are simultaneously supported in the heel region. Since few vehicles in Germany are equipped with such a cruise control, the foot has to be kept on the accelerator pedal without lateral support. Premature fatigue and cramping arise. The object of the invention is to support the foot, and possibly the lower leg, by means of a lateral contact surface. The object is achieved by a side rest which has at least one prismatic base part forming an acute-angled triangle and extends above the ankle height of the foot. The foot rest is used in all vehicles having an accelerator pedal (drive pedal). <IMAGE>

Abstract: Blood purification apparatus comprises a dead-end system in which blood from the patient is allowed to flow through one or more purification modules, such as a dialyzer, a hemofilter, a hemoperfusion column and an oxygenator, into a resiliently walled reservoir, which is conveniently a standard blood bag. The direction of flow of the blood is then reversed by exertion of sufficient pressure on the bag to push the blood back through the purification module to the patient's circulation. Thus, since the reservoir is of available capacity, being of resilient material for example, the capacity of the apparatus remains equal to the volume of extra-corporeal blood.

Abstract: The device for fastening a rail to a tie (3) comprises an elastic intermediate plate (34) and above that a rigid pressure-distribution plate (35) which is mounted between the foot (2) of the rail (1) and the tie (3), guide plates (10, 11) fastened on the tie (3) for the lateral guiding of the rail foot (2), and clips (38) which act on the rail foot (2) and clamp the rail (1) onto the tie (3). The elastic intermediate plate (34) which protrudes on either side under the foot (2) of the rail (1) extends in each case into a receiving chamber (16, 17) formed by the guide plates (10, 11). As a result, the elastic intermediate plate (34) can produce a sufficient resistance moment against horizontal forces, so that a tilting of the rail is prevented. At the same time, the substantial forces of the clips (38) can be transferred directly over the guide plates (10, 11) to the tie (3), so that there is no possibility of a non-uniform deflection of the elastic intermediate plate (34) during assembling and thus of faults occurring in the inclination of the rails.
