Patent CA-1286083-C (CA)
Title: Ground anchors
Inventor: STOKES BRUCE F
IPC: E02D5/80
Filed: 1986-09-26
Granted: 1991-07-16
Abstract: ABSTRACT     A ground anchor is provided comprising a first part engageable within an anchoring medium such as, for example, the ground, along an insertion axis; a second part to which loads are, in use, attached; and linking means interconnecting the first and second parts yet permitting displacement of the second part with respect to the insertion axis.  Thus when load is applied to the second part after the first part has been inserted within the anchoring medium the second part can alter position without moving the first part and thus reduce the effective loading on the first part.  The second part preferably includes supplementary anchoring which penetrates the surface of the anchoring medium upon application of load to the anchor.

Title: Method and apparatus for the manufacture of dimensionally stable, liquid-impermeable, flexible press bands, particularly for wet presses of paper making machines
Inventor: KRENKEL BERNHARD
IPC: D21F3/02
Filed: 1987-04-06
Granted: 1993-03-30
Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to a method of and an apparatus for the manufacture of dimensionally stable, liquid-impermeable, flexible press bands, particularly for wet presses of paper making machines. With known manufacturing methods for such press bands, the provision of a structured surface for liquid dis-charge on the outer surface of the press band, which faces the fibrous web or the felts, is achieved either by reversing the press band after removal from the casting mould so that the structured surface becomes the outer surface of the band while the smooth surface forms the inside thereof, or by grinding drainage ducts. into the outer surface of the press band. But especially in the case of small band diameters, reversing of such cast press bands causes serious problems and entails considerable expenditure, wherein the risk of damage to the band cannot be excluded and grinding of the drainage ducts is just as expensive. To simplify the manufacturing process and to eliminate reversing of the press band after removal thereof from the casting mould, the inner wall of the centrifugal tube is provided with cavities and/or depressions which upon casting of the free-flowing mixture are filled there-with to form raised surface portions on the outer surface of the finished press band, so that in a sub-sequent pressing operation liquid to be discharged may be drained between said raised portions, and the completely cast press band is ground to finished size on the inside thereof.

Abstract: Abstract of the Disclosure An  intraocular  lens  for  patients  having  macular degeneration.   The  intraocular  lens  comprises  a  first portion including a diverging lens,  and a second portion including a converging lens which is laterally offset from the  diverging  lens.   The  converging lens  provides  the patient with substantially the same vision he or she had prior to implantation of the intraocular lens,  i.e.,  the decreased visual  acuity  normally  associated with macular degeneration, while providing unmagnified and unrestricted peripheral vision.  The diverging lens, when combined with converging  lens  means  located  outside  the  eye  (e.g.  a spectacle  lens),  provides a magnified retinal image of a given object with increased visual acuity but a restricted visual field.  Thus, the intraocular lens of the invention provides  the patient with the choice of unmagnified but peripherally   unrestricted vision   or   magnified   but peripherally restricted vision.

Abstract: ABSTRACT       In  root  canal preparation, there is provided a smooth sided  pilot  ended  endodontic K-type file, a K-type reamer file,  a H-type Hedstroem file, an S-type file, and a R-type file (rhomboid), with the safe end of the instrument or file measured  from  D1  from 1-3 mm before the cutting edges are developed on all types of endodontic cutting instruments and on  all  sizes  from 06-140.   The smooth sided pilot end of the  apex file can be incrementally increased based upon the increasing size of the instruments.  For example, #15 = 1 mm smooth  sided  pilot  end,  #20  = 2 mm safe end, #25 = 3 mm smooth  sided  pilot  end, etc.  This is to be used for ease with the step back preparation technique.  The smooth sided pilot  ended  apex file instrument has the ability to act as path-finder  into  the  root canal without damaging the apex portion  during  this  phase.   The smooth sided pilot ended endodontic  file of this invention avoids forcing debris and filling  material  out the apex and creates a proper apical stop  of  proper retention and resistance.  The smooth sided pilot  ended  endodontic file of this invention is necessary to achieve the critical phase of root canal preparation.

Abstract: APPARATUS FOR REMOVING BARK FROM CUT LOGS               ABSTRACT OF THE DISCLOSURE An apparatus for removing bark from cut logs where the logs, stacked parallel to each other, are brought both to rotate and to move back and forth in the direction of their length during si-multaneous movement sideways and in restacking.  The movement of the logs is achieved by feeding the logs into a stationary con-tainer equipped with at least one level movable bottom section, a feeder side slightly sloped toward the bottom section, two planar, vertical gable sides and a discharge side sharply angled toward the bottom section. The bottom section of the container has at least one oblong section vertically and laterally movable, which, at its short end, is hung to rotate on eccentric shafts or the like.  At least one of the eccentric shafts is equipped with a drive mechanism meant to cause, in each bottom section, a move-ment, as seen from the long side of the bottom section, and a chiefly circular path in which the imagined axis of rotation of the bottom section is horizontal and at right angles to the length of the logs.
