Title: Derotating orthotic devices for the correction of scoliotic deformities
Inventor: RIVARD CHARLES-HILAIRE
IPC: A61F5/02
Filed: 1994-12-22
Granted: 2003-12-16
Abstract: A series of ortheses for the treatment of scoliotic deformities are each adapted for obliquely applying dynamic derotational forces on the thorax and lumbar spine of the user in opposite directions combined with a kyphosing action on the thorax and a lordosing action on the lumbar spine. The orthoses are designed in order that the correcting forces can be applied on the user's trunk with various degree of mechanical force while allowing for complete or partial mobility of the trunk. The various orthoses can treat small moderate and substantially severe deformities which are supple or rigid. A supple orthosis (100) for small and supple curves comprises a thoracic garment encircling th e upper thorax (102), short pants (104) to provide a gri p around the pelvic girdle and the upper thighs, and upper and lower semi-elas tic straps (106, 108) having supple thoracic and lumbar pads (120, 122), respectively, attached respectively to the garment and the pants . The straps (106, 108) which connect the pads (120, 122 ) encircle obliquely thetrunk for exerting the derotational forces and the kyp hosing and lordosing actions. For moderate and supple cu rves, semi-rigid thoracic, lumbar and pelvic pads (120, 122) are incorporated in t he orthosis (100). For the rigid curves, the orthosis co mprises a supple plastic shell encircling the pelvic girdle, a vertical member exten ding posteriorly and upward from the shell and comprisin g thoracic and lumbar pads. Semi-elastic strap means extend anteriorly between the pads while encircling obliquely the trunk. The vert ical member can be integral with the shell or, for more rigidity, can consist of metallic member attached to the shell.

Title: Improved meat product casing and method of shirring
Inventor: MERCURI ENRICO
IPC: A22C13/02
Filed: 1994-05-10
Granted: 2003-01-14
Abstract: This invention relates to a casing (10) for use in encasing meat products. The casing (10) comprises a combination of a first tubular casing (11) which may comprise a fibrous casing material and a knitted tubular net (12) located around and substantially concentric to the first tubular member (11). The tubular net (12) comprises circumferential elastic cords (13) and longitudinal cords (14), and the relative diameter of the circumferential cords (13) to the first tubular casing (11) are such that when the casing (10) is being filled the circumferential cords (13) are placed under tension prior to the first tubular casing (11) reaching its maximum diameter. This enables the circumferential cords (13) to absorb some of the hoop stress before it is applied to the first tubular member (11) thereby preventing splitting of the first tubular member (11) which might otherwise occur without the tubular netting (12). The specification also discloses a method of shirring the casting (10) to an injection nozzle (16) which enables even spacing of the tubular net (12) around the first tubular casing (11) as the casing (10) is drawn from the injection nozzle (16). The method involves inflation of the casing (10) prior to shirring onto the injection nozzle (16).

Granted: 2005-07-26
Abstract: The present invention relates to a chain of elastic bands (1), comprising at least two elastic bands (3), wherein adjacent elastic bands are joined to one another by means of at least one bridging piece (4). The longitudinal direction (A) of the elastic bands preferably extends transversely to the longitudinal direction (C) of the chain of elastic bands (1). The chain of elastic bands can have been produced from a flat, sheet-like web of elastic material (9), such as rubber, preferably natural rubber, in which essentially oval elastic bands (3) have been formed. The elastic bands have a constant width (B) all round. Adjacent elastic bands are preferably joined to one another by at least two bridging pieces (4), which are preferably each arranged at a transition between the adjacent longitudinal strips (5) and arc-shaped strips (6). The chain of elastic bands according to the invention can be rolled up into a roll or can be folded up to form a harmonica-like stack. Chains of elastic bands of this type can be produced, for example, from rubber which is still in the unvulcanised state or from an elastic plastic.

Title: Method and apparatus for synchronizing communications in a satellite based telecommunications system
Inventor: GARRISON ARTHUR L
IPC: H04B7/212
Filed: 1997-04-15
Granted: 2002-01-01
Abstract: A  method  and  apparatus  are  provided  for  maintaining synchronous return and forward communications links between user terminals and earth stations communicating via a common satellite in a satellite based telecommunications system.  Each user terminal maintains a closed synchronization loop with its associated earth station based on timing and frequency error offset signals received by the user terminals.  The user terminals update their internal timing and frequency generators based on the received error offset signals.  In an earth station sharing embodiment, one of the earth stations  is  designated  as  a  master  earth  station while  the remaining stations are designated as slave earth stations with respect to a common satellite.  The slave earth stations monitor a return link between at least one user terminal and the master earth station.  The slave earth stations update their internal reference timing  and  frequency  signal  generators,  in  order  to  remain synchronous  with the  return  link  between the monitored user terminal and the master earth station.  The slave earth stations maintained synchronous forward links by requesting synchronization update  information  from  the  monitored  user  terminal.    Upon receiving a request,  the monitored user terminal calculates a difference in timing and frequency between frames received from the requesting slave and associated master earth stations.  The user terminal transmits the difference in timing and frequency along its return link.   The slave earth station updates its forward link timing  and  frequency  reference  signal  generators  to  remain synchronous with the master earth station.

Abstract: Proteases generally tend to reduce the activity of coagulation factor VIII by degrading the molecule. The present invention relates to a process for reducing the detrimental influence of metal-dependent proteases upon recombinant factor VIII molecules, by adding an inhibitor of metal-dependent proteases to a solution after harvest. The solution is suitably the harvest solution or any aqueous solution being fed to or leaving the primary isolation, being the initial step of the purifying sequence. The inhibitor is selected from: i) complexing agents with a stronger affinity for the metal ion of the protease than for the ion or ions stabilizing the factor VIII molecule and ii) compounds structurally related to the natural substrate of the protease and containing an electronegative moiety. The presence of an inhibitor, preferably a complexing agent, after harvest allows for a prolonged harvest period and considerably higher yield with essentially retained factor VIII  activity. The invention further relates to an aqueous solution containing recombinant factor VIII which has been purified according to the present process and use of such an aqueous solution, for the manufacture of a medicament for administration to a patient having the symptoms of hemophilia. Also, the invention relates to a method for treatment of hemophilia by administration of a therapeutically effective amount of recombinant factor VIII which has been purified according to the present process.
