Abstract: The present invention provides a timing recovery technique for baseband-coded data sequences which applies to line codes with inband timing information embedded in periodic signal transitions, such as zero-crossings. The technique utilizes a selection of data patterns, like mark-to-mark, which have zero-crossings at the "center" of a transition from a positive to negative mark. These so-called "bipolar patterns" consist of two polar-signals of opposite polarity sharing neighboring baud intervals. Because the random nature of a data sequence gives timing information a statistical behavior, a timing recovery system recovers a timing average, the efficiency of the system being given in terms of the timing variance. According to the present invention, a low variance estimate for the bipolar-pattern-center timing signal is obtained by proper filtering.

Abstract: The invention relates to a device for the working of more or less loose material, such as mixing and levelling of animal feed in a storage holder, working of a surface layer of ground material, such as the aerating, levelling and harrowing thereof and/or the removing of weeds therefrom, and the chopping of those weeds, the distributing and mixing of mixed manure through a surface layer of ground material, the distributing, chopping and spreading of manure substances or the removal of silage from a storage heap, which device com­prises: 
at least one rotor with a number of elongate working members (3,7,10,36,65,77,110), such as wires, rods, bars or strips, the ends of which are fixed to two attachment elements (1,2,5,6,9,28,35,75,76,63,107), such as two groups of spokes or two discs, coupled to a rotating shaft (4,12,61,81,111,112) such that they extend at least more or less parallel to and at an inter­val from the rotating shaft, and 
driving means for rotary driving of the or each rotor. 
     The invention has for its object to embody a device such that the chance of breakage or otherwise damaging of the working members is greatly reduced. The invention further aims to execute a device such that if a working member must nevertheless be replaced, this replacement can be carried out in a minimal time. 
     The invention provides with a view thereto a device of the type referred to in the preamble which is characterized by spring means (80,137,113) holding the working members under tensile stress. If desired a spring member can be added to each wor­king member. Preference is however given to a cheaper but nonetheless completely reliable embodiment which displays the feature that the rotating shaft comprises at least two tele­scopically co-acting shaft parts (111,112) locked against relative rotation and that the attachment elements are forced away from each other by the spring means.

Abstract: A tissue disintegrator is described and is adapted for use with an endoscope for the surgical removal of tissue. The disintegrator comprises a cutter blade (20) mounted at the end of an elongated drive shaft (16) the other end of which is connected to means for rotating the drive shaft (16). The drive shaft (16) is supported for rotation in a hollow sheath (18) and a suction path parallel to the drive shaft leads from the cutter blade to an attachment (22) for connection to a source of suction, so that disintegrated tissue can be removed by suction from the region in which the cutter blade (20) operates. In order to prevent the cutter blade (20) from binding on the tissue, the region in which the cutter blade operates may be flushed with a physiologically acceptable irrigation liquid or a reciprocating motion may be imparted to the drive shaft (16).

Abstract: A preobjective scanning optical system for use with a rotating mirror scanner employing LEDs or lasers to electronically reproduce photographs. The optical system includes a doublet disposed before the mirror and a triplet disposed after the mirror. Instead of collimating, the first optical system along with the mirror forms a virtual, curved image of the LEDs or lasers as the scanner rotates and includes a first and a second lens which, in combination, correct the image for on-axis spherical and axial color aberrations. The triplet has net positive power and its three lenses, in combination, correct for off-axis aberrations such as astigmatism, coma, and lateral color aberration but can be under corrected for field curvature because its object is the curved virtual image.

Abstract: Control device for the roll stabilisation of a vehicle, with actuators (3, 3', 3'', 3''') arranged between the wheel carriers or wheel-guiding elements (2, 2', 2'', 2''') and the vehicle body (13) and producing force approximately in the vertical direction. The control device is activated only when threshold values for the lateral acceleration of the vehicle and for the rotational angle of the steering wheel are exceeded. With the control device activated, the actuators (3, 3', 3'', 3''') produce a rolling moment on the vehicle body which counteracts rolling movements, initially entirely or for the most part at the rear wheel axle. In a transition time dependent on parameters, the rolling moment distribution between the front wheel axle and the rear wheel axle is then altered to a predetermined, fixed rolling moment distribution by the control device. …<IMAGE>…

Abstract: To separate the glycolipids from a lipid mixture containing complex lipids, the neutral lipids are separated, where appropriate, by chromatography on silica gel and the glycolipids are then separated from the phospholipids by chromatography on a boric acid gel. If appropriate, the gangliosides can be subsequently separated from the fraction containing the glycolipids by solvent in the presence of water. The fraction containing the glycolipids can be treated by ion exchange chromatography to separate the nonacidic glycolipids from acidic glycolipids. Similarly, the nonacidic phospholipids and the acidic phospholipids can be separated by ion exchange chromatography of the fraction containing the phospholipids.

Abstract: A high performance composite hose having enhanced durability, reliability and longevity for use in high pressure, high temperature and/or vibrational environments such as turbocharged truck, bus, automobile, marine and generating engines. The composite hose comprises one or more plies of balanced fabric having a high performance elastomer adhered to the inner and outer surfaces of each fabric ply. The balanced fabric is formed as woven sheets from filament yarns resistant to high temperatures. Balanced fabric sheets are sectioned at a predetermined angle to the filament yarns to form balanced fabric plies. The yarns of the balanced fabric plies are orientated at the predetermined angle with respect to the longitudinal axis of the composite hose such that the composite hose has a predetermined longitudinal flexibility to compensate for stress effects resulting from high temperatures, high pressures and/or vibrations. Concomitantly, the balanced fabric plies restrict the radial flexibility of the composite hose to preclude collapse or ballooning of the hose during start up, irregular or steady state operation.
