Abstract: To produce a twice-cut folded product in DIN A5 format which is provided with a transverse fold at the longitudinal edge, the cutting and pointing cylinder (12), which is downstream of the pointing and folding blade cylinder (7), is provided with folding blades (21) and a pointing delivery cylinder (13), fitted with folding flaps (23), is arranged downstream of the cutting and pointing cylinder (12). By this means, the folded copies, which were cut once on the circumference of the cutting and pointing cylinder (12), can be cut a second time and provided with a transverse fold in addition to the first longitudinal fold. However, delivery in DIN A4 format without this transverse fold is also possible in that the folding blades (21) and folding flaps (23) of the cylinders (12) and (13) are put out of action, i.e. switched off. …<IMAGE>…

Abstract: An electrophotographic photoreceptor comprising a photoconductive layer (103) comprising a photoconductor, a support (101, 102) for the photoconductive layer (103) and a surface layer (107) formed on the photoconductive layer (103) and comprising a curable resin film (105) and inorganic insulator pieces (106) having a size larger than the film thickness of the curable resin film (105). In order to prevent the image blurring of an a-Si:H photoreceptor, on the outermost surface of the photoreceptor was formed a surface layer having a structure in which inorganic insulator pieces (106) have protruded from the curable resin film (105). Since the curable resin (105) is of high resistance and shows no quality change by corona irradiation, and besides the protruding inorganic insulator pieces (106) prevent the abrasion of the resin, the surface layer (107) having a long life and excellent humidity resistance, durability for corona irradiation and abrasion resistance can be realized. Further, by covering the surface layer (107) with a fluorine-containing lubricant, the surface layer (107) having a low friction coefficient and excellent cleaning characteristics is obtained, and besides the resin constituting the surface layer (107) absorbs little moisture. As a result, it becomes possible to use the a-Si:H photoreceptors without a heater. Also, the surface layer (107) of the present invention can be removed and then re-formed.

Abstract: An amino-acid ester compound can be cyclized into a cyclic amido-carbonyl compound by contacting the amino-acid ester compound in a liquid medium with a heterogeneous acidic ion-exchange substance. For example, 2-hydroxy-3-(2-aminophenylthio)-3-(4-methoxyphenyl)propionic acid, methyl ester, threo form, can be cyclized in an aqueous mixture into cis-2-(4-methoxyphenyl)-3-hydroxy-2,3-dihydro-1,5-benzothiazepin-4(5H)-one by employing a sulfonated polystyrene-divinylbenzene ion-exchange resin in its acid form, e.g., Dowex 50X4-400, at yields exceeding 85 percent of theory, and the product can be used to make diltiazem hydrochloride.

Abstract: Adiabatic mode control and structural reproducibility are achieved by a tapered semiconductor waveguide structure wherein semiconductor guiding layers are interleaved with stop-etch layers and each guiding layer extends further along the propagation axis of the waveguide further than the guiding layer immediately adjacent thereabove to create a staircase-like core or guiding structure. Cladding regions of appropriate semiconductor material having a lower index of refraction than the tapered core structure may be added to completely surround the tapered guiding structure. The profile of the tapered structure is realizable as any desired staircase-like shape such as linear, parabolic, exponential or the like. Additional layers of higher index of refraction semiconductor material may be included in the cladding region to permit additional beam shaping of the expanded spatial mode propagating along the tapered waveguide. 
     Photolithographic masks defining successively larger exposed areas are aligned, deposited over the waveguide structure, and then removed following each etching step. Material selective etching techniques are employed to remove exposed (unmasked) portions of guiding layers. In sequence, the exposed, formerly underlying portions of the stop-etch layers are then removed using material selective etching. Iteration of the above process steps permits a tapered waveguide structure to be defined.

Abstract: A flexible applique or patch (30) is used to modify a circuit board (10) by attaching the flexible applique to the back side of a circuit board needing rework. The flexible applique has circuit paths (28') on both its front and back side. The flexible applique also has circuit paths which pass from the front side to the back side of the applique or patch. If additional electrical components are required by the rework, the back side of the applique or patch is provided with pads to which surface mount electrical components are easily attached. Implementing the rework using the applique or patch is simple and easy. The front side of the patch is positioned on the back side of the circuit board, and then attached to the back of the circuit board either by soldering down points along the edge of the patch or by providing an adhesive on the front side of the patch. Using this method, both simple and complex reworks can be quickly accomplished. <IMAGE>

Abstract: A solids level detecting assembly (11) is particularly useful for detecting the level of paper pulp (or wood chips during the manufacture of pulp) in a vertical vessel (10) . A first hollow shaft (12) is affixed at a portion thereof to a vessel with a first end (13) extending into the vessel. A second shaft (20), concentric with the first, is disposed within it and connected at a first end (23) thereof to the first end of the hollow shaft, and to a paddle (plate) (22). A sensing device, including a movable core element (28) of high magnetic permeability material, is mounted to a free end (24, 40) of the second shaft. A stationary core element (43) is mounted adjacent the movable element so that a twisting motion of the first shaft as a result of solid particles acting on the plate changes the flux in the core elements. A flux detector (comprising a pair of coils (70, 71) and a voltage detector (76)) detects the changes in magnetic flux in the core elements, and indicates the change on an indicator (77), which thus illustrates the level of pulp or chips within the vessel.

Abstract: A birdcage knee coil operated in quadrature in an NMR imaging system includes a pair of like butterfly coils each formed from a strip transmission line formed on a common dielectric substrate. The pair inputs the quadrature signals created by the birdcage coil to a combiner output circuit. Each butterfly coil of the pair comprises a pair of wings of like area connected by a common transmission line so that currents induced by a magnetic field on the ground conductors of one wing oppose and cancel the currents induced by that field on the ground conductors of the other wing. The transmission line forming each butterfly coil has opposing ground conductors of the same transverse width with a center conductor equally spaced between the ground conductors and a transverse width of about one tenth that of the ground conductors. The pair of coils are arranged symmetrically relative to the birdcage coil to provide an electrically balanced system.

Abstract: A method and means is described wherein servo sectors (30) written on a disk (50) (or servo sections written on a tape) are equally spaced on a given track and read during seek, settle and track following operations. An algorithm is used to determine the allowable time separation between servo sectors (30) (or sections) on a track and lengths of associated data sections, such as data sectors or variable length records, that may be accommodated on the disk or tape in such manner that each of the servo sectors (or sections) equally spaced on a given track is located within a data field (27′) of a data sector (M) or within an identification region (22′) or immediately after an address indicating mark (52) (such as address mark or index mark). The rate at which the servo sector (or section) is sampled is constant and independent of the number and lengths of the data sections. As a result of this independent relationship, this technique is suitable for CLD recording, to banded disks using sectored servo as in conventional FBA, and also even to non-sectored architectures, such as count-key-data (CKD), wherein the data is written in records of variable length, and to tape drives formatted in FBA of CKD.
