Patent CA-2018426-A1 (CA)
Title: Continuously-operating press
Inventor: BIELFELDT FRIEDRICH B
IPC: B30B5/06
Filed: 1990-06-06
Abstract: ABSTRACT      The present invention relates to a continuously-operating press suitable for producing compressed flat products from suitable material, having a press bed and a press top which can be moved towards or away from eachother to form an adjustable press gap and having flexible endless metal bands which circulate about said press bed and said press top over drive rollers and deflection rollers. The metal bands serve to transmit pressing force to the material and to pull the material through the press gap.  The bands are supported by means of roller rods whose axes run transversely to the direction of movement of the bands against the press top and the press bed, the roller rods being fed into the press gap by means of roller chains and by means of feed devices located in an entry zone of the press gap orthogonally relative to the longitudinal median of the press. In the entry zone of the press gap, a series of teeth are provided on pressure devices acting as pilgrim step mechanisms such that the teeth intermittently penetrate gaps separating adjacent roller rods in order to properly mutually align the rods.  Moreover, flexible clamping elements exert increasing pressure upon the roller rods as the rods traverse the entry zone.  By properly aligning the roller rods in this way, rapid wear of the roller rods and elements for feeding the rods can be avoided.

Filed: 1990-12-31
Abstract: There    is    disclosed    an    interference spectrophotometer which collects data while monitoring the position of a movable mirror by providing quadrature control to  accurately  perform coherent  addition  of  data.   The spectrophotometer includes a main interferometer, a control interferometer, a sliding controller controlling movement of the movable mirror, an A/D converter converting analog data obtained by the main interferometer into digital form, a register for holding data obtained by   one scan of the movable mirror, a memory for accumulating data obtained by numerous scans of the movable mirror, an up/down counter receiving the output signals from two detectors included in the control interferometer, and a decision part.  When the counter's value varies, the counter causes the A/D converter to perform its A/D conversion.   Then, the decision part checks the counter's value after the A/D conversion.   If this value differs from the count value obtained prior to the  A/D conversion,  the  data  held  in  the  register  is discarded.

Patent CA-2034239-A1 (CA)
Inventor: MCGAFFIGAN THOMAS H
IPC: H05B6/10
Filed: 1991-01-15
Abstract: This invention provides a system for providing heating in an alternating magnetic field using lossy heat producing magnetic particles. This invention discloses a system comprising a combination of particles wherein the first particles are lossy heat producing particles, which have a preselected Curie temperature to provide self-regulating heating in the alternating magnetic field, and the second particles are nonlossy particles which have high permeability which are not heat producing particles but which maintain the coupling of the magnetic circuit and maintain the desired magnetic field focus and intensity through the area in which the first lossy heat producing particles are positioned. Thus, in this invention, when the first lossy heating particles approach or are at their Curie temperature and have declining permeability and would otherwise lose the desired coupling with the magnetic circuit, the second nonlossy high permeability particles maintain the coupling of the magnetic circuit as well as the desired intensity of the magnetic field through the first lossy heating particles to provide the desired field strength throughout the heating period. This invention prevents premature loss of heating due to loss of coupling of the magnetic circuit with the lossy heating particles and provide other advantages. This invention also provides magnetic particles coated with an electrically resistive coating, which coated particles exhibit useful properties in the above particle systems.

Title: Full length non-draping necktie rack
IPC: A47G25/74
Filed: 1991-07-19
Abstract: ABSTRACT OF THE DISCLOSURE A  rack  for  neckties includes a  base  member  from  which project a plurality of stationary elongated pins laterally spaced from  one another a small specified distance calculated to allow the  insertion  and  removal of the tail end  of  neckties.   The closeness of the pin spacing permits the accommodation of approx-imately  seventy-five neckties per foot of rack length with  all of the ties being retained in a fully suspended manner, free  of folds  and  wrinkles.  The retention of the  neckties  is  accom-plished  due to one or more features evident in the  construction of  the  tail end portion of all neckties and which  provides  an increased bulk in the material of the tie.  The dimension of this increased  bulk exceeds that of the spacing between two  adjacent pins and accordingly serves to retain the neckties.

Title: Diffraction grating and method of manufacture
Inventor: LEE ROBERT A
IPC: B42D25/29
Filed: 1990-09-04
Abstract: A diffraction grating providing an optically var-fable image includes a pixellated diffraction grating in which each pixel is an individual optical diffraction grat-ing so that the pixellated diffraction grating when illumi-nated generates an optically variable image. In another aspect the grating in some or all of the pixels of a dif-fracting grating formed by a regular matrix of pixels is arranged such that a reproduction of the grating by ref-lection contact printing generates a zero-order pattern which is grossly flawed by Moire or Talbot fringe ef-fects. A method of forming the diffraction, grating in-cludes producing a counterpart pixellated diffraction grating of a substantially optically invariable image wherein each pixel of the optically invariable image is maped to a respective pixel of the pixellated diffraction grating: Each grating pixel is an individual optical dif-fraction grating of the associated pixel in the optically invariable image, so that the pixellated diffraction grit-ing when illuminated generates an optically variable rep-roduction of the optically invariable image.
