Title: Clamping mandrel and stripping combination for a core sleeve of a rolled web, particularly a paper roll to supply a printing machine
Inventor: HAMMER JOSEF
IPC: B65H16/02
Filed: 1991-02-28
Granted: 1994-12-27
Abstract: An ejector ring (18) surrounds an axially movable mandrel (6), on which a core sleeve or tube (19) for a paper web roll, for example a newsprint roll, can be supported.  The ejector ring is resiliently supported on the holder structure, for example on a holder arm (1) and surrounds the mandrel, and is movable parallel to the mandrel. The structure is space-saving, provides for secure retention of the mandrel and is thereby capable  of supporting heavy paper rolls, while providing for reliable stripping of core sleeves off the mandrel upon retraction of the mandrel into the holder structure, for example for exchange of a paper roll.

Title: Low profile vehicle construction
Inventor: CLELLAND WILLIAM F
IPC: B62D21/02
Filed: 1992-03-18
Granted: 1995-05-02
Abstract: A cargo vehicle includes a vehicle chassis and a body.  The vehicle chassis has a pair of chassis frame rails to which the body is mounted.  The body has a rear structural section and a front structural section.  In the rear structural section, a pair of body longitudinal rails are mounted above the chassis rails.          The body rails and the chassis rails are separated by a thin, vibration attenuating sheet of resilient material.  A plurality of floor support members are mounted on and extend from the sides of the body and chassis rails, in contrast to prior art cargo vehicles which mounted the floor support members above the body rails.  The thin, resilient separator material and the lowered floor support advantageously reduce the height of the cargo section floor.  A ramp storage region is defined in the space within the body rails.  In the front structural section, the ramp storage region is not required.  A second pair of body longitudinal body rails is provided in the front section above the chassis rails.  The front body rails have a reduced vertical dimension, permitting installation of floor support cross members on top of the body rails while providing a floor plank mounting height consistent with that of the rear structural section.

Title: Data recording and reproducing apparatus
Inventor: KOJIMA KUNIO
IPC: G11B7/00
Filed: 1993-01-22
Granted: 1996-08-13
Abstract: A data recording and reproducing apparatus uses a rewriteable optical disk with pre-recorded absolute address information, and comprises a data compression circuit for dividing  and  compressing  continuous  digital  data  into compressed plural data blocks, an expansion circuit to restore the compressed data to the original expanded form, and a buffer memory.  Data is compressed in discrete data blocks and is recorded sequentially block by block to the optical disk.          The compressed data is likewise read block by block from the disk during data reproduction.   Using the data expansion circuit to expand the compressed data one block at a time, the data recording and reproducing apparatus can reproduce the original continuous digital data stream.  Plural continuous digital data selections can thus be reproduced by alternately fetching data for the plural selections from the disk in compressed data block units and temporarily storing the data to a buffer memory for expansion.

Abstract: n interféromètre Sagnac (19) est défini par un coupleur à fibres optiques 50:50 à quatre points d'accès (20), dont deux points de sortie (38, 40) sont couplés ensemble par un amplificateur laser à semiconducteurs non linéaire (3) en série entre une paire de fibres optiques (22, 24).  Les pertes de couplage entre les points d'accès (38, 40) et l'amplificateur (30) sont différentes.  Une impulsion d'entrée couplée au point d'accès (34) du coupleur (20) se divise en deux parties, rétropropagées de l'un des points de sortie (38, 40) à l'autre.  Les parties retournent au coupleur (20) avec une intensité qui dépend du déphasage relatif.  Il est ainsi possible de commuter une impulsion d'entrée au point d'accès d'entrée (34) situé entre les points d'accès d'entrée (34 et 36), selon l'intensité de l'impulsion d'entrée.  Le dispositif peut assurer la commutation selon l'intensité à des niveaux de puissance optique inférieurs à 250 mu.W.

Abstract: A data demodulator of a receiving apparatus for spread spectrum communication for removing the phase difference remaining after detection for improving reception quality.      In-phase and quadrature axis received signals are multiplied by pseudonoise codes, PNI(t) and PNQ(t) and the results are averaged aged by averaging sections for calculating the correlation.      By performing correlation processing, pkO cos ~ , -pO sin ~, pkO sin ~, and pkO cos ~ are output when the amplitude of receive path signal is assumed to be p, the phase difference to be ~, and a proportional constant to be kO.  These signals are multiplied by in-phase and quadrature axis received signals and the results are added by adders, thereby removing the effect of the phase difference ~.  The signal is used for data demodulation and data recovery circuit.
