Title: Structural epoxy paste adhesive curable at ambient temperature and process for preparation thereof
Inventor: GARCIA GILBERT
IPC: C08L63/00
Filed: 1987-04-13
Granted: 1992-03-24
Abstract: ABSTRACT OF THE DISCLOSURE           A  process  for  preparing an epoxy resin and  a  process  for preparing a hardened and cured epoxy  resin  adhesive  is provided, together with the  epoxy  resins and adhesives made thereby.  The epoxy  resin  is  prepared by mixing together about 76  parts  per  hundred  of  a novolac epoxy resin, about  19  parts per hundred of a bisphenol F epoxy resin,   and   about   5   parts   per  hundred  of carboxy-terminated     butadiene     acrilonitrile, heating  the mixture to a temperature of from about 290  to  about 350 degrees Fahrenheit for a time of from  about  two  to about  three  hours, and then cooling.    An epoxy adhesive is prepared by mixing 100  parts  of  the material so prepared with about parts  of a curing agent consisting essentially of   diethyltriamine.      The  resulting  adhesive mixture   has  a  paste-like  consistency  that  is easily  applied  and  cured at ambient temperature. The  shear  strength of the cured adhesive is about 4000 psi at ambient temperature and about 2000 psi at  250 degrees Fahrenheit.  The cured adhesive has excellent  peel  strength, indicating ductility and toughness.   It also exhibits acceptably low levels of  particle  outgassing,  permitting  its  use  in spacecraft applications.

Patent CA-1314604-C (CA)
Title: Control circuit for regulating a knife
Inventor: ARLT GERHARD
IPC: B26D3/10
Filed: 1988-05-18
Granted: 1993-03-16
Abstract: ABSTRACT           This invention relates to a control circuit for regulating a knife.  To manufacture synthetic pockets from a continuous foil tubing web, a knife in the web produces an undulatory cutoff.  In the prior art, the knife is supported by a rotating cutter head which can be moved diagonally to the guide motion of the web.  The cutter head is shifted and rotated through a groove of a drum controller.  The disadvantage of this is that a separate drum controller is required for each undulatory cutoff.  The control circuit should make it possible to manufacture various types of undulatory cutoffs.  The control circuit of the present invention has a subdivider circuit which divides the length of a cutoff into straight-lined pieces and sinusoidal pieces.  The sinusoidal pieces are divided in a divider circuit into longitudinal increments.  The course of a sinusoidal part is stored in a memory bank in the unit scale.  The matching lateral increment is determined in the unit scale by interpolation for each longitudinal increment,these lateral increments being multiplied with the amplitude of the cutoff in a multiplier.  The actual resultant lateral increments are stored in sequence in a further memory bank.  A synchronous and sequence circuit feeds the lateral increments stored in the additional memory bank to a first motor control circuit which regulates the motor for the lateral movement of the knife carrier.  The motor disposed on the knife carrier for rotation of the knife is regulated by a second motor control circuit to which the lateral increments are also fed, but in a sequence which corresponds to the first mathematical derivative of the sequence fed to the first motor control circuit.  The circuit makes it possible to produce cutoffs of various sizes by inputting the length and amplitude.
