Abstract: A cassette tape recording and/or reproducing apparatus in which a single pinch lever (24) pivotally supports a pair of pinch rollers (25, 26) corresponding to a pair of capstans (12, 13) rotatable in directions opposite to each other. A head operating member such as a head base (16) or the like is moveable in a first direction (A, B) in response to a play lever or a movement of the play lever, and can be moved in a second direction (C, D) perpendicular to the first direction so that the pair of pinch rollers are alternately urged against the pair of capstans. Tape guides (22a, 22b) and a head supporting portion (22) are formed unitarily with the pinch rollers, allowing the relationship between the pinch rollers, the tape guides and the head to be determined with ease, which becomes advantageous in forming the tape path. Further, the number of parts can be reduced.

Abstract: A circuit breaker having a trip mechanism 17 comprising a primary armature 69 which is attracted toward a bimetal 53 by magnetic flux produced by a predetermined overcurrent flowing through the bimetal to unlatch an operating mechanism and open electrical contacts, includes a pivoted supplemental armature 71 which is also attracted toward the bimetal by the overcurrent and which bears against and urges the primary armature toward the bimetal to thereby reduce the predetermined overcurrent at which breaker opens the electrical contacts. The supplemental armature comprises a flat strip of magnetically permeable material which is bent at one end to form a hook 77 which merely drops into a recess 79 in the breaker housing 3. Integral flanges 85 on the strip form a magnetic yoke which concentrates the magnetic flux to increase the sensitivity of the magnetic trip function.

Abstract: The intensifier (38) for delivering ultra high pressure water to a cutting head of a water jet cutting apparatus has a power piston and 
cylinder assembly (42) connected to piston members extended into pumping chambers in housings (49) located at opposite ends of the piston and cylinder assembly. Inlet poppet valves (147) located in the pumping chambers control the flow of water from inlet passages into the pumping chambers. Outlet poppet valves allow ultra high pressure water to be pumped out of the pumping chambers into an accumulator fluidly connected to the cutting head. Hydraulic fluid under pressure is sequentially directed to opposite ends of the piston and cylinder assembly (42) with a solenoid operated reversing valve. Limit switches (102, 103) operable in response to movement of the piston members control the reversing valve. Linear motion transfer mechanisms (113, 122) are moved with ramps (70, 82) on the piston members (68, 79) to actuate the limit switches (102, 103) to control the reciprocating action of the piston and cylinder assembly (42).

This is achieved by every connecting piece being a connecting nozzle 16, over which the assigned lower filter disc sector 19 with the outlet orifice 17 is pushed along a drop distance, by the drop distance being adapted to the distance 25 between the lower filter disc sector 19 and the shaft 3 and by a ring segment 26 being pushed by means of a rotary movement about the shaft 3 between the shaft 3 and the lower filter disc sector 19. The lower filter disc sectors are pushed onto the connecting nozzles and the ring segments are pushed under the shaft. <IMAGE>

Abstract: Test support for the analytical determination of a component in a sample fluid with the aid of a specific binding reaction of two bioaffinity binding partners. A plurality of test layers is arranged so that they are successively wetted by the fluid and form a fluid transport pathway, where one of the test layers is a fixing layer (18) which has a porous support matrix. The first of the two binding partners is fixed on the latter. The fluid which contains the second binding partner flows through the fixing layer (18), at right angles to its surface, on the test support (10). 
<??>A substantially complete binding reaction in an extremely short time is achieved on flowing through the preferably very thin fixing layer (18) in that a microporous synthetic layer with a pore size P of at least 0.01  mu m is used as support matrix, with, at the same time, the size D of the second binding partner and the pore size P of the synthetic layer being mutually adjusted so that the pore size P is at least two and no more than ten times as large as the size D of the second binding partner.

Abstract: A method is disclosed for improving the signal-to-noise ratio of reflected echo signals produced by an acoustic transducer in a borehole televiewer. An array of acoustic receivers is used in close enough proximity to the transducer to receive the reflected echo signals as directly reflected signals. The array of receivers can be arranged both above and below the transducer, either rotating synchronously with the transducer or being stationary. The signals received by the receivers are analyzed to determine the true amplitude and angle of reflection of the reflected echo signals, and to determine the rugosity of the borehole wall.
