Abstract: An expander for insertion into and expansion of a soft bag (20, 40, 302) comprising a device (10, 11, 13, 15, 136, 137, 200, 250, 300, 350) which is folded or collapsed to a flat state or spread apart to an expanded state. The soft bag is collapsed to a compact form in the flat state for shipment. In the expanded position, the bag is expanded to give the appearance that it is filled. Some embodiments use a resilient member (18, 38, 146, 230, 280, 281, 330, 380) to automatically urge the device from a flat position to its expanded position when compressive forces are removed from the bag. Other forms use a cord (72, 98, 150) for manually moving the expander device into its bag-expanding position. To provide for a greater extent of expansion in relation to the length of the device in the flat position, an expanding device (200, 250, 300, 350) having four sequentially arranged sections (2Il-214, 261-264, 311-314, 361-364), each of which is articulatable with respect to each adjacent section is provided in some embodiments. Expansion of a cylindrical bag (302) is facilitated by a generally rigid insert (333, 334, 382) in certain embodiments that is articulatable to better conform to the curved shape of the side portions.

Abstract: There are described improvements applied to an apparatus for automatically winding of coils on forms or winding holders (F,11) having a remarkable longitudinal extension in comparison with the transver­se sizes, particularly suitable for dipole or quadrupole magnets. The apparatus, already generally known from EP-A-0278924 provides for the reciprocating oscillating movement of said form (F) by about 180°, taken as a whole, being obtained, at least at each end, by meshing a pinion (15) from a geared motor (12, 12a) with a toothed half-ring (19) having a central portion (19a) fixedly mounted to said coil holder (F,11) and two symmetric outer wings (19b, 19c), being hinged at both sides of said central portion (19a), suitable to tilt alternatively by gravity, according to the rotation direction, as soon they are no longer support­ed by an arc-shaped stationary guide (34) which is coaxial with the said half-ring (19) and such as to minimize the radial clearances The apparatus also comprises a template carriage (2) to support the reel holding arm (3) for the conductor (10) to be wound and preferably provides for a non contemporary but sequential action of the ram means in the length direction of the form (F) for positioning each length of laid down conductor (10).

Abstract: A headrest for motor vehicle seats has a frame (10) which is surrounded by upholstery and arranged on two parallel holding rods (28) so as to be vertically adjustable and swivellable about a horizontal axis. The frame forms on the two sides in each case one housing (11, 12) which holds the associated holding rod and has two approximately parallel walls (15, 16) which extend transversely with respect to the common plane of the holding rods, one cylindrical joint shell (17) and two walls (18, 19) which diverge upwardly and transversely with respect to the approximately parallel walls in a wedge shape. In the cylindrical joint shell, a joint body (25) which holds the respective holding rod in the manner of a guide bushing is mounted. The joint body (25) consists of two parts (23, 24) which are arranged coaxially with respect to one another and connected to one another by a spring (22), an upper part (23) of which parts has cylindrical contours (26) corresponding to the joint shell (17) and forms a joint part. On the other hand, a lower part (24) serves to guide and detachably lock the holding rod (29) in the vertical direction. By means of the constructional and functional division of the joint body into an upper part which essentially carries out a joint function only and a lower part which essentially fulfils a guide function and by means of the elastic connection of these parts with a spring, functioning of the joint body in a manner which is completely free of play is ensured. Possible deviations in the desired diameter of the passage hole on the joint body for the guide rod are compensated by elastic spring force. By means of this compensation of possible fitting inaccuracies between joint body and guide rod, a low-noise adjustment and swivelling of the headrest is made possible.   <IMAGE>

Abstract: An integrated optical pickup device for a magnetooptical recording medium (e.g. a magnetooptical recording disk) and/or an optical recording medium (e.g. an optical recording disk) in which a plurality of focusing grating couplers are formed on an optical waveguide layer manufactured on a substrate. A light reflected from a magnetooptical disk or an optical disk is guided by the focusing grating couplers into the waveguide layer to be separated and to be converged therethtough. The converged lights are detected so as to produce a tracking error signal, a focusing error signal, and an information readout signal. The plural focusing grating couplers are fabricated at an identical location on the waveguide in a superimposed fashion. This increases the utilization efficiency of reflection light per each unitary area of the focusing grating couplers and hence the signals are obtained in a stable state. 
     Between a semiconductor laser and a collimation lens, there is formed a composite beam splitter having two reflection surfaces. Reflection lights from the magnetooptical disk are respectively reflected by these reflection surfaces and are then received by photosensors. Analyzers are disposed respectively on front sides of the photosensors. The analyzers respectively have polarization directions orthogonal to each other. Each photosensor includes three-partition photodiode. The beam sizing method and the push-pull detection methods are used for detecting the focusing and tracking errors. 
     The optical pickup device can also used to read data from an optical disk. 
     A prism is disposed between a semiconductor laser and a collimation lens. The prism has two reflection surfaces. Reflection lights from a magnetooptical disk are respectively reflected by these reflection surfaces to be received by photosensors. On front sides of the photosensors, there are respectively arranged analyzers respectively having polarization directions orthogonal to each other.

Abstract: Projecting units for large picture projection are known which operate in accordance with the principle of modulation of polarised light. In light valves for picture modulation of the polarised light passing through, the necessary polariser in most cases consists of a polarisation foil, as a result of which only a maximum of 50% of the incident light can be utilised. According to the invention, an interference-type polariser, which provides for almost loss-free polarisation of the incident light, is used as replacement for this polarisation foil. Due to the special design of the interference-type polariser, the necessary volumes of the modules of the interference-type polariser and also of adjacent elements such as mirror, condenser and IR/UV absorption filter are minimised. Due to the special design with IR and UV-transmitting mirror, a large proportion of the thermal radiation is already filtered out at the interference-type polariser. <IMAGE>

Abstract: A method is disclosed for making more efficient the particle-mediated germ line genetic transformation of bean species such as soybean. After a particle-mediated transformation event, in the absence of a selectable marker gene, relatively large numbers of plants must be regenerated to find the relatively low likelihood germ line transformation events which have occurred. It has been discovered that using in the transformation process a marker gene linked to the gene of interest, and by excising a segment of the stem of the shoot during the regeneration process and assaying the sequent for the marker gene, certain patterns or phenotypes can be identified in the stem segment which are associated with an increased frequency of germ line transformation events. As the plants are regenerated, other indices of gene expression, at the first trifoliate leaf stage and at the third or fourth trifoliate leaf stage, also serve as markers of the likelihood of germ line transformation. By using these markers in the relatively early stages of plant regeneration to assay for likelihood of germ line events, it is possible to concentrate regeneration efforts on plants most likely to yield germ line events, and to discard the others, so as to lower the burden and effort in achieving a desired number of transformation events.

Abstract: A frequency divider circuit is responsive to first (16) and second (14) digital input signals and an input clock signal (12) for providing an output clock signal (30) operating at a frequency equal to that of the input clock signal divided by the ratio of the first and second digital input signals. A register (78-88) is initialized to a predetermined digital value for providing a first digital output signal. The first digital input signal is subtracted (56-64) from the first digital output signal to form a second digital output signal for the first logic state of a digital control signal; otherwise the second digital output signal is set equal to a least significant portion of the first digital input signal for the second logic state of the digital control signal. The second digital output signal and the second digital input signal are added (66-74) together for providing the next value of the first digital output signal which is stored back in the register to repeat the cycle. A most significant portion of the first digital output signal provides the digital control signal. The first logic state of the most significant bit of the first digital output signal also enables the output clock signal in sync with the input clock signal.

Abstract: A digital encoder for compressing a digital input signal derived from an analog signal to reduce the number of bits required to represent the analog signal with low quantizing noise. In the encoder, a digital input signal representing the analog signal is divided into three frequency ranges. The digital signal in each of the three frequency ranges is divided in time into frames, the time duration of which may be adaptively varied. The frames are orthogonally transformed into spectral coefficients, which are grouped into critical bands. The total number of bits available for quantizing the spectral coefficients is allocated among the critical bands. In a first embodiment and a second embodiment, fixed bits are allocated among the critical bands according to a selected one of a plurality of predetermined bit allocation patterns and variable bits are allocated among the critical bands according to the energy in the critical bands. In the first embodiment, the apportionment between fixed bits and variable bits is fixed. In a second embodiment, the apportionment between fixed bits and variable bits is varied according to the smoothness of the spectrum of the input signal. In a third embodiment, bits are allocated among the critical bands according to a noise shaping factor that is varied according to the smoothness of the spectrum of the input signal. All three embodiments give low quantizing noise with both broad spectrum signals and highly tonal signals.
