An internal combustion engine includes four cylinders arranged concentrically about a driving shaft and each having two opposing pistons which are linked to wobble elements via respective connecting rods. The wobble elements are supported by the driving shaft and transmit the movement of the pistons into a rotational movement of the driving shaft. Each wobble element consists of two portions which...

A new acidic polycyclic ether antibiotic, CP-63,517, having the formula: (I) and cationic salts thereof produced by submerged aerobic propagation of Streptomyces endus subsp. aureus, ATCC-39574, a new strain of microorganism isolated from a soil sample in Japan, a process for producing this antibiotic and methods for its use to improve feed utilization, promote growth of cattle and swin...

Composite pulses are employed in NMR imaging for time-reversal of nuclear spins in a transverse planar region of a sample to produce spin-echo signals. The composite pulses comprise a sequence of pulses for producing a 90 DEG rotation of the spins about a first transverse axis, a 180 DEG rotation of the spins about a substantially orthogonal transverse axis, and a 90 DEG rotation of the nuclear...

A contact body especially for evaporative cooling of a flow of useful air by means of a flow of cooling air. The contact body is built up of layers with slots existing between the layers, which slots are passed by the two air flows separated from each other, the heat exchange being effected through the walls of the layers. The layers comprise panels rigid in shape and composed of plane plates loca...

Wettable fibers and/or filaments are prepared from olefin polymers, especially linear low density copolymer (LLDPE), by incorporating into said olefin polymer at least one wetting agent of the group comprising (a) an alkyoxylated alkyl phenol along with a mixed mono-, di-, and/or triglyceride, (b) a polyoxalkylene fatty acid ester, or (c) a combination of (b) and any or all parts of (a).

An electro-optical device characterised in that it comprises: (A) a semiconductor body: and (B) at least one pnictide-rich layer for guiding light waves in the said body is disclosed. Referring to the accompanying diagram, an electro-optical device 20 may comprise a semiconductor body 22 and pnictide-rich layers 24 and 26. The semiconductor layer of an opto-electronic device has one or more films...

A mirror (1) is provided and pref. has a dia. of approx. 20 cms., and is spherical. It is provided with two lines (2,3) of which the first is the intersection between a dia. plane and a mirror plane. The other line is elliptical The mirror is positioned in front of the golfer at the ball position when the player is in a primary stance, and is adjusted so that the primary line (2) cuts the mirror p...

An apparatus for fastening a sleeve (1) onto a shaft (2) comprises a wedge box (3), which by means of a fastener (4) can be pressed into the shaft in a space (5) between the sleeve (1) and the shaft (2). The wedge box (3) has a section (6) fitted with a thread to engage with a corresponding thread on a nut (9), which is designed so that when it is turned it enables the withdrawal of the wedge box...

The brake is applied by pedalling backwards, and its disc is maintained on the crank wheel (4) by a stop component. The disc activates the brakes of the cycle by means of an attached wire (8) or rod. The brake also has an arm (9) at the free end of which is a component (10) which, when back-pedalling occurs, locates against the cycle chain (12) and slackens it.

The frame assembly is so formed that it can be packed in a flat package without dismantling, and has two frames (2,5) connected to one another by articulations comprising loop-forming parts (12) on the lower frame and pins (13) on the upper. The lower frame also has a transverse stop part (8) and a snap part (10) connected to it by an arc-shaped union piece (9). The upper frame can be pivoted by a...

Two lateral sections of an additional 'pulpit' gunwale are articulated to an ordinary gunwale. Both funwales are rotatable around a pref. common axis running transverse to the longitudinal direction of the boat. - The additional gunwale can be lowered from a first position, in which it fulfills its normal role, to a second position where it forms a support or bumper outside the hull of the craft.
