Abstract: The appliance has a flat, hollow, elastic basic body which is filled with fluid or air and is divided at right angles to its flat surface into two adjacent chambers (2,3). The chambers are of identical size and shape and contain separate volumes of fluid (4,5). They are joined integrally by a shared rigid base (6). The chambers are semicircular or kidney shaped. The internal height of the chambers is less than their internal width. Each chamber has a peripheral side wall (11,12) joining the cover forming the foot support surface (9,10) and with a parallel base. A stabiliser plate (15) fits into a central recess in the base of the basic body and has a back-tapered edge (14).

Abstract: PCT No. PCT/DE97/00288 Sec. 371 Date Oct. 5, 1998 Sec. 102(e) Date Oct. 5, 1998 PCT Filed Feb. 10, 1997 PCT Pub. No. WO97/30094 PCT Pub. Date Aug. 21, 1997The present invention concerns a process for producing dispersions of water-soluble vinyl polymers and a stabilizer for carrying out this process. Such water-soluble, particularly cationic vinyl polymers, are employed on a large scale as process expediters for carrying out, for instance, separating processes in water treatment or waste-water purification, respectively, in the paper, coal and ore industries, in oil production or also in the food stuff industry, among others, for floculation, coagulation, retention or dewatering. According to the present invention, water-soluble vinyl polymers are homo- or copolymerized in the presence of a dispersion stabilizer of the invention. The stabilizer consists of a graft copolymer whose backbone is formed by polyethylene oxide and its grafted branches of cationic vinyl monomers. Among others, cationic, hydrophobically modified vinyl monomers can be advantageously employed. Copolymerizations can be carried out between cationic or non-ionic hydrophobically modified vinyl polymers and cationic or non-ionic, non-hydrophobically modified vinyl polymers.

Abstract: According to the law on electromagnetic compatibility of 1 January 1995 all electrical apparatus must have a certain resistance to interference by electromagnetic fields. Especially in the case of systems having large dimensions, such as trains, it is at present not possible to carry out such a test economically using conventional methods. The invention relates to a test device which makes such testing possible and beneficial. According to the invention, a test device consists of a novel arrangement of an impulse-generating wave guide (IEW) which consists of parallel, electrically conductive individual rods which are connected by a head electrode and, via a rail-like spark gap which is in a straight line with an impulse-conducting waveguide (IFW) which is identical in structure but longer, is closed at right angles with a terminating resistor. A return line is connected to said terminating resistor. Several of these IEW, IFW, return lines and terminating resistors arranged as described above can be connected in parallel in a modular manner via a shared release mechanism and therefore create a testing space suitable for a large system.

Abstract: FIELD: medical engineering. SUBSTANCE: device has two sucking disk areas lying opposite that are higher and thicker. The sucking disk cross-section is optionally elongated in the direction of mentioned areas of its wall. Rod is optionally disposed in the hole on the sucking disk preventing from excessive contact lens suction into the sucking disk and participating in organizing one or more lateral openings for making communication between internal sucking disk cavities and pneumatic pear. Another version of the device deals with sucking disk having protrusion with an opening for holding contact lens by sucking pressure. Sucking disk wall has two opposite-lying slits. The pneumatic pear optionally has rubber balloon disposed in the hole for preventing the contact lens from being excessively sucked in into the rod opening. The pneumatic pear internal cavity partially filled with balloon communicates with the opening via one or more slots on the balloon end face. Both versions of the device have sucking disk wall continued in the pneumatic pear direction or transformable into pneumatic pear wall. The first version involves taking the device with fingers placed on the sucking disk near its bottom on the same side as the elongated sucking disk wall areas are. The second version involves taking the device with fingers placed on the pneumatic pear near sucking disk bottom on the same side as its elongated wall areas are. The third version involves taking the device with fingers placed on the sucking disk near its bottom from the slot sides. When pressing the fingers close together, the edges of the elongated areas go apart in all versions and the pneumatic pear becomes compressed. When reducing finger compression degree the mentioned edges of the elongated areas come closer and the pneumatic pear becomes more released. As a result of the action edge areas catch the contact lens being taken from object and pear releasing maintains lens suction to sucking disk edge or to sucking disk protrusion opening. The diverging edge areas leave the lens to positioned on the object and pear compression causes repulsion of the lens by means of compressed air from the sucking disk to the object. EFFECT: enhanced effectiveness and reliability of operation; simplified design. 17 cl, 3 tbl

Granted: 2001-10-20
Abstract: FIELD: plasma-arc generators. SUBSTANCE: main electrode and opposing electrode provide for double-rail structure capable of generating plasma-arc discharge that can move continuously over closed loop. Such continuous movement of plasma-arc discharge is attained due to specific design of main electrode. The latter primarily has tubular body with first edge usually connected to dc supply through at least one point of connection and other working edge used for electric-arc discharge. Tubular body is divided by at least one slit (gap) joined with one point of connection and stretching between first and second edges so that they form second edge gap in vicinity of second edge. Two sides of second-edge gap are located in transmitting and receiving regions of arc, respectively. These two regions and respective point of connection are positioned so that arc column generated will be always moving along second edge from transmitting region to receiving one up to location farther along motion from projection of point of connection onto second edge (relative to direction of movement of plasma arc). Due to such motion arc column will continuously cross second- edge gaps. EFFECT: improved crystal structure of solidified metal; ability of axial displacement of main electrode in the course of operation. 24 cl, 10 dwg
