Abstract: PANEL FILE                Abstract of the Disclosure A panel file     , for the storage of flat, flexible data elements    , consists of plural, vertically overlapping pockets    , the entrances (140) of which are formed by a plurality of vertically spaced, horizontally extending strips of resilient material.  The strips are arranged so as to have an upper edge which overlaps the lower portion of the next upwardly adjacent strip.  The strips are fastened together at their lateral margins. The lower portions of the pockets are formed by a support sheet      which is attached to the panel on the surface opposite the pocket entrances.  The support sheet is cut so as to have a column of inverted "V"-shaped straps each having a vertex       which is attached to the back of a strip.  The strips have an upwardly concave bottom edge        with a central vertex     at the point       where the support sheet strap is attached to the next downwardly adjacent strip.  Thus, the attachment point between a strip and a strap is located in an area of the panel having the thickness of only one strip, which area is below the lower edge of an upwardly adjacent strip and above the upper edge of a downwardly adjacent strip.  Thus constructed, the overlapping pockets are individually openable, and do not become increasingly constrictive as the panel is filled.  The panel thus constructed also has a minimum number of overlapping layers at any point.

Abstract: ABSTRACT OF THE DISCLOSURE An electronic weighing apparatus comprises a slit plate displaceable in association with the weight of an article placed on a weighing pan.  A photosensitive device is provided in the vicinity of the  slit plate for generating a train of pulses responsive to the slits in association with the displacement of the slit plate.  The slits are provided on the slit plate such that the pulses are obtained from the photosensitive device only if an when the amount of displacement exceeds that corresponding to a predetermined weight.  The slit plate is further provided with a magnetic shield plate at a position before the photo-sensitive device intially detects the slits, when the slit plate is displaced.  A permanent magnet and a reed switch are provided facing each other through the slit plate at a mechanical zero point, such that the reed switch is turned on if and when the slit plate is displaced and the magnetic shield plate is removed from the mechanical zero point, whereby various components of the electronic weighing apparatus are energized by a battery.  The pulse train obtained from the photosensitive device is counted by an up/down counter, which is initially loaded with the data asso-ciated with the above described predetermined weight, when the reed switch is turned on.  Accordingly, the up/down counter starts counting the pulse train, starting from the above described initial count value associated with the above described prede-termined weight.

Abstract: 21.12.79.                      15                 PHB 32645 ABSTRACT      An accumulation-mode CCD converts into electrical signals an electromagnetic radiation pattern e.g. of infra-red radiation. The device body (1) may be of monocrystalline silicon and has a radiation-sensitive region (2) which is of one conductivity type determined by dopant (e.g. sulphur, platinum, indium or thallium) having an energy level or levels sufficiently deep in the semiconductor band gap that substantially all of said dopant atoms are un-ionized at the device operating temperature.  By this means said region (2) is substantially free of majority charge carriers in the absence of said radiation, and majority charge carriers trapped by said dopant atoms can be released upon excitation by the radiation. A first ohmic contact (5,6) to said region (2) supplies majority charge carriers to said dopant to replace charge carriers released by the incident radiation.  An electrode system (11 to 14) on one major side of the region (2) permits electric fields to be capacitive-ly generated in the region (2) for accumulating the released majority carriers below the electrode system (11 to 14) as charge packets corresponding to the incident radiation pattern and for transporting said charge packets laterally across the region (2) to an output (15,16) from the region (2). Instead of the Figure 1 arrangement, the contact (5,6) may be at the same side as the electrode system (11 to 1) instead of the opposite side, and a single-phase CCD electrode system possibly with a rectifying junction instead of an insulating layer (17) may  be used.  The device is converted from a 21.12.79.                      16                  PHB 32645 surface-channel to a bulk-channel CCD by the addition of a surface layer (20) of said one conductivity type at the said one major side of said region (2) below the electrode system (11 to 14).  The surface layer (20) is separated from the first contact (5,6) by the region (2) and comprises conductivity-type determining dopant (e.g. arsenic) having an energy level or levels sufficiently shallow in the semiconductor band gap that at the operating temperature atoms of this shallow-level dopant are ionized.  An ohmic contact which may also serve as the output (15,16) is electrically connected to said surface layer (20) for extracting the majority charge carriers generated by the shallow-level dopant and thereby forming in said surface layer (20) a space-charge zone which forms in the body (1) a potential minimum spaced from the surface.     It is suggested that Figure 1 should accompany the abstract when published.

ABSTRACT:                  A helical scan video recorder comprises a head support for a plurality of magnetic heads, which head support is detachably mounted on a cylindrical portion of a drive spindle with the aid of a clamping sleeve on the head support, which sleeve is concentric with the drive spindle, and of a clamping ring which is deformable on the clamping sleeve between a released position and a clamping position, which clamping ring radially deforms the clamp-ing sleeve, so as to centre and clamp the head support on the drive spindle.  The clamping ring has no interruptions in its annular wall, so that its structure is integral and, after mounting, the clamping ring through a symmetrical radial deformation locally exerts a clamping pressure which is distributed substantially uniformly over the cir-cumference of the clamping sleeve, so that a highly repro-ducible centring of the head support relative to the axis of rotation of the drive spindle is obtained.

Abstract: SEGMENTED DRUM BAR HELIX PRINTER                      Abstract Disclosed is an improved form of a mosaic printer of the bar helix type.  The helical raised threads on the printer drum instead of being continuous are broken into segments which are offset axially on the drum.  This produces a significant increase in throughput by re-ducing waiting time for the drum to rotate a section of continuous thread into alignment with a hammer at the start of a new helical pattern.
