Inventor: FOCKE HEINZ
IPC: B65B41/12
Filed: 1988-10-03
Granted: 1993-05-04
Abstract: Abstract (in conjunction with Figure 1) Packaging machines are often supplied with a web of pack-aging material of double width.  During transport, the web of material (11) is sub-divided into two part webs (12,13) by means of a central longitudinal cut.  The exact run of the web of material (11) and of the part webs (12,13) is monitored by edge-sensing members (21; 25,26).  Any deviations from the correct position are transmitted as error signal to web-adjusting members (24; 27,28).  These are each equipped with two deflect-ing rollers (32,33 or 59,60 or 62,63) arranged at a dis-tance from one another and intended for deflecting the web of material (11) or part web (12,13).  The two de-flecting rollers are each adjusted in order to adjust the web run.

Title: Process for the recovery of the desorbate that occurs  during the desorption of charged sorption materials, and an apparatus for carrying out this process
Inventor: PEINZE REINHOLD
IPC: B01J20/34
Filed: 1988-10-31
Granted: 1993-12-07
Abstract: ABSTRACT           In order to be able to recover the desorbate of high-boiling point organic substances that have a tendency to form mists and/or low-boiling point organic substances that tend to decompose such as, for example, halogenated hydrocarbons and which occur during the recovery of the charged sorption agents during desorption, and in order to be able to do this economically with-out interference by residual charging or corrosion problems, it is proposed that the desorbate be condensed in a direct heat exchanger, with the desorption gas that is to be cooled below the condensation temperature of the desorbate being brought into contact with recycled desorbate that has been super-cooled suf-ficiently beneath the condensation temperature of the desorbate, and thereby cooled.  To this end, the recycled desorbate is removed from a tank, cooled in a heat exchanger to a temperature below the condensation temperature, and moved into a direct heat exchanger with the help of a pump.  Within the direct heat ex-changer the desorption gas which is to be cooled and which originates from a desorbing adsorber, is moved in  with the help of a blower and cooled down to the desired temperature to separate the desorbate.  The cooled desorption gas can be recycled.

Filed: 1988-12-16
Granted: 1991-11-26
Abstract: ABSTRACT OF DISCLOSURE      A thin-film coating method for laminating thin-films to opposing surfaces of a substrate and an apparatus for accomplishing the same. A pair of tack members 10E are respectively disposed on opposite sides of the substrate and are moveable in a direction perpendicular to the direction of conveyance of the substrate so as to temporarily tack forward end portions of the thin-films to the substrate. In addition, compression rollers 16 are movably disposed with respect to the substrate such that the compression rollers can respectively contact forward end portions of the thin-films after the tack members have been removed from the substrate. The compression rollers are rotatable to thereby convey the substrate and to cause the thin films to adhere to the opposing surfaces of the substrate. In addition, a pair of wet rollers 30 are rotatably disposed in contact with the opposing surfaces of the substrate in a position upstream to the tacking position. The wet rollers 30 deposit a void space preventing agent to the substrate so as to prevent void spaces from developing on the contacting surfaces between the substrate and each of the films.

Abstract: Apparatus and method for fabricating films, especially films containing vinylidene chloride copolymer, wherein the process is susceptible of continued operation over an extended period of time greater than a few days. The process typically can operate for at least 2 weeks between shut downs for cleaning the die. The apparatus comprises a coextrusion feedblock in combination with an annular extrusion die having a crosshead mandrel, and means for conveying the exit stream from the feedblock to the die. The particular apparatus combination especially reduces the rate of carbon buildup in the extrusion apparatus during extrusion of VDC-copolymer, such that the extrusion process can be operated for a longer timebetween shutdowns for cleaning and maintenance of the die. The invention furtherincludes novel tubular films made with the apparatus and methods of the invention, and packages made from the films. In general, the method of the invention produces tubular films having more layers than the annular extrusion die has annular orifices.
Patent CA-1338213-C (CA)
Inventor: BRIGHT ROBERT GRANVILLE
IPC: B60R13/06
Filed: 1989-01-04
Granted: 1996-04-02
Abstract: A  sealing  strip  for  a  vehicle  door  opening  has  a generally  channel-shaped  gripping  part  supporting  a tubular sealing part.  Initially, the side walls of the channel of the gripping part are splayed apart so as to enlarge  the  mouth  of  the  channel.   This  eases  the application  of  the  gripping  part     to  the  normal mounting flange surrounding the vehicle door opening. The flange can pass freely between gripping lips on the opposite inside walls of the gripping part.  A suitable tool is then employed to press the side walls of the channel  towards  each  other  so  as  to  render  them substantially  parallel,  thus  pressing  the  lips  into gripping and sealing contact with the flange surfaces, this    configuration    being    therefore    resiliently maintained by a metal carrier embedded in the gripping part.    One  of  the   sealing  lips   is  particularly advantageous for secondary sealing purposes because  it is  directed  outwardly  of  the  mouth  of  the  channel, unlike the other lips.  The initial outward direction of this lip is maintained after fitment of the strip of the flange,  because  of the  initial  splaying  apart  of the side walls of the channel.

Each position sensor includes spaced Hall cells secured to a movable sensor head, with limit signals hardwired via the multiplexing board directly to the control system.  The PM motor is a low cost motor which rapidly drives the tool unit in accordance with the output of the sensor.  The motor drive system includes a fast drive mode in an open loop for rapidly moving the several tool units and sequentially to slowly move the tools to the final position.  Thus, the computer based control unit is provided with individual input commands for each axis of the tool unit and positions all the tool units in a matter of 3 to 8 minutes.

Each prosthetic disc capsule has a bladder enclosing a fluid containing a therapeutic material  that  is  slowly  diffusible  through  a semipermeable membrane of the bladder.   The fluid filling the semipermeable membrane preferably is an aqueous solution that has gel-like properties that afford  a  viscosity  and  velocity-shear  behavior imitating the natural rheology of intradiscal nuclear tissue.    Those  properties  are  obtained  when  the aqueous solution is of a mucopolysaccharide such as hyaluronic acid or sodium hyaluronate.
