Abstract: An oil sump 1 of an internal combustion engine has a recess 3, into which dips a suction funel 5 of an oil pump. The funnel is spaced slightly from the oil sump floor 7. A honeycomb-shaped insert 8 is positioned in the recess 3 at a slight spacing from the oil sump floor 7. The height b of the insert 8 amounts to a multiple of the spacing a from the oil sump floor and also a multiple of the side length c of the substantially square cross-section of the chambers 11 of the insert 8. As a result, the oil flowing back from the engine, which is strongly foamed with air because of the rotating motion of the crankshaft drive, can become de-foamed in the relatively high chambers 11, whereby the oil foam in the chambers 11 rises and air-free oil in the chambers drops down to the oil sump floor 7. This ensures that the oil pump, which is pumping out from the oil sump floor 7, essentially draws in air-free oil.

Abstract: A window spacer assembly is disclosed having tubular members interconnected by corner pieces. The corner pieces are provided with flexible fingers which create an interference fit with the tubular member ends and resist forces which tend to pull the assembly apart.

Abstract: An electric motor has a disk brake which is designed as an electromagnetically operated spring-loaded brake, acts as a standstill brake and has a thin, elastically flexible brake disk (12) of spring steel. This brake disk (12) is immovably fixed on the motor shaft (2) between an axially movable, rotationally fixed armature (8) of the electromagnet and a stationary brake part (13) which forms the outer brake housing. The annular stator (4) of the electromagnet surrounds the motor shaft, with formation of a free annular space which offers room for further attaching parts, for example a tachometer generator and/or a phase-angle sensor, or else for a ball bearing carrying the shaft. Borne axially displaceably in the stator (4) is a coil (6) which, in the braking state, is pressed by compression springs (7) against the armature (8), which for its part presses an annular rim zone (12a) of the brake disk (12), with elastic deformation of the same, against the stationary brake part (13).

Abstract: Laser beam focusing head having an unfocused-beam input, a focused-beam output and a lens located between the said input and the said output; the said head comprising a reflecting mirror between the said lens and the said output, and the said lens being located in such a position as to be directly invisible by the said output.

Abstract: A device for lifting or lowering an invalid patient for movement between wheelchairs and/or beds, chairs, commodes and automobiles is disclosed which has a base, an upright, and a patient support member pivotably secured to the upright. A pivoting element pivots the support member for raising or lowering the patient. There is also provided a generally vertical plate for securing the patient's knees.

Abstract: A travelling wave tube comprising a tube and a helix mounted in the tube, the helix being made of diamond and being coated at least partially with an electrically conductive material.

Abstract: A thermal insulator is disclosed which comprises fibrillated staple fibers exemplified by fibrillated fibers of poly (p-phenylene terephthalamide). The fibers are fibrillated on a carding machine equipped with metallic clothing.

Abstract: This invention relates to a non-contact electro-optical displacement follower which captures the image of a target or device under test optically, converts the said image into an electron image by optical-electrical conversion, and measures displacement. It forms a variable voltage which moves the electron image on the displayer to the desired location and can be applied to each deflection coil (8, 9) by arranging a variable voltage generator (18h, 18v) attached to each deflection coil so that the set-up and adjustment of the equipment and measurement preparations can be performed easily. Moreover, this equipment possesses a displayer (A1, A2, A3, A4) to indicate which position (up, down, right or left) the electron image moved due to the variable voltage, in spite of the fact that the electron image may be damaged temporarily if adjustment is excessive.

Abstract: The circuit arrangement processes two input signals which are periodically variable as a function of the position of a moving part and particularly of the angle of rotation of a rotating part and which are phase-shifted by approximately 90.degree. with respect to each other and have a sinusoidal or sine wave-like characteristic. In an inverting circuit, inverted input signals are generated. A curve change-over switch assembles from the input signals and the inverted input signals two sequences of similar signals sections which are divided in a divider circuit which forms quotient signals which represent the variation of the tangent function. The y signals are then converted in a tangent/arc tangent converter by forming the arc tangent function into an at least approximately sawtooth-shaped voltage signal which consists of path-proportional path signals.

Abstract: A multitube heat exchanger is provided with a take-apart fitting. The fitting is coupled to one end of the exchanger product tube. A cap ring is secured to the inner tube of the exchanger. An end cap adapted to seal against the cap ring is secured to the fitting. A split ring clamp serves to urge the end cap against the cap ring by virtue of a chamfered surface on the clamp urging against a complementary chamfer of the end cap.

Abstract: Two intaglio printing plates having a total length equal to the circumference of the cylindrical barrel (1) of a plate cylinder are prepared. The cylindrical barrel (1) is expanded radially, and on the portion of its surface corresponding to the first plate (4) to be attached an epoxy film is deposited. The first plate (4) is applied on the epoxy film in the exact position. On the remaining part of the cylindrical barrel (1) one or a plurality of metal sheets (5) are deposited for ensuring the continuity of the cylinder surface. The plate (4) to be attached is surrounded by a tightening ribbon (6) covering completely the plate (4). Heat is used for softening the epoxy film and the ribbon (16) is tightened by exerting tractive forces beginning from the center of the two ends of the ribbon and advancing towards the peripheral edges. The epoxy film is allowed to set, the ribbon (6) and the sheet or sheets (5) are removed.

Abstract: Processing is based on print carriers in the form of security paper webs or security paper sheets, containing security paper prints which are arranged in the manner of matrices in transverse rows and longitudinal rows and on which spoilt notes are identified by a mark which can be read by a reading instrument. The print carriers pass, in succession, by a reading instrument which detects the positions of the spoilt notes and feeds them into a computer for storage, a cancellation printer controlled by this computer, which provides spoilt notes with a cancellation print, and a numbering machine. The numbering mechanisms of this numbering machine are moved forward by the computer in such a way that always the satisfactory security paper prints, placed in succession in any longitudinal row, are serially numbered, the spoilt notes being neglected.

Abstract: The disclosure is of the use of an injectable formulation of disulfiram for the treatment of alcoholism. One formulation comprises disulfiram and a biodegradable polymer. Another formulation comprises a slurry of disulfiram in normal saline. After injection, disulfiram is released from the injection site in a sustained-release manner.
