Title: A method for making metal matrix composites by the use of a negative alloy mold and products produced thereby
Inventor: BECKER KURT J
IPC: C22C47/08
Filed: 1989-10-13
Abstract: Abstract The present invention relates to a novel method for forming metal matrix composite bodies, and the metal matrix composite bodies produced according to the novel method.  Particularly, a permeable mass of filler material is formed into a preform by first forming a negative cavity in a matrix metal and thereafter placing said permeable mass of filler material into said cavity.  An infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are also in communication with the filler material, at least at some point along the process, which permit the matrix metal, when made molten, to spontaneously infiltrate the permeable mass of Filler material, which at some point during the processing, may become self-supporting.

IPC: H01P1/213
Filed: 1990-01-05
Abstract: A combiner arrangement in a radio base station includes a number of waveguide cavity resonators operating as channel filters.  According to the invention, each resonator is divided into two substantially equal cavity resonator parts. One base station transmitter is connected to one of the resonator parts and another is connected to the other resonator part.  The decoupling of a resonator is effected by two clamp-like elements situated at the center of the resonator.  The coaxial connection to the antenna consists of coaxial bales between the resonators.  All the resonators are connected in series with the antenna.

Patent CA-2014621-A1 (CA)
IPC: H01L21/82
Filed: 1990-04-17
Abstract: The interconnection costs of electronically linked objects is minimized by the successive partitioning of the initial logic design. The partitioning is based upon the electrical properties of the drivers and loads of the linked objects forming the design. Further, time critical connections are weighted so as to further minimize interconnection cost. A further method refines the result of the successive partitioning by calculating each linked object's contribution to the overall delay of the design. Both the design of device function and timing and the physical realization of the electronically linked objects are solved jointly to make use of the information available from the logical and physical designs.

Title: Belt fastener system
Inventor: SCHILLINGER HARALD
IPC: F16G3/10
Filed: 1990-06-27
Abstract: BELT FASTENER SYSTEM             ABSTRACT OF THE DISCLOSURE A two-piece  fastener system for joining opposed ends of a belt material to form a continuous belt, each joining member having at least two sets of channels and lips formed in a direction to extend across the width of the belt material. The channels and lips are formed to be mutually mating such that the lips of one joining member fill the corresponding channels of the other joining member, and vice versa. The joining members are coupled to opposed ends of the belt material such that one joining member has its channels open in an upward direction while the channels of the other joining member are open in a downward direction, so that looping of the belt material to bring the opposed ends in proximity to form an endless belt will result in the joining members  being oriented in an arrangement allowing their mutual mating.  The joining members may be bonded to exterior surfaces of the belt material or, through use of a belt end splitting tool of the present invention,  bonded  into slits formed in the belt ends. Alternately, the joining members may be vulcanized to the belt ends or formed integrally  thereon. The joint thus formed may be reopened by separating the joining members along their lengths.                     (?)

Abstract: SECURE KEY MANAGEMENT USING PROGRAMMABLE           CONTROL VECTOR CHECKING                          Abstract The  invention includes  a  control vector  checking code repository located either within the same system as the cryptographic facility or alternately remotely from the system containing the cryptographic facility.   The control vector checking code repository will be linked to the cryptographic facility by one of several means.  A first  means   for linking  the   repository   to   the cryptographic facility would include a physically secure data communications link.  A second means for connecting the repository to the cryptographic facility would be by using an insecure channel with authentication,  wherein either a modification detection code or alternately a message authentication code would be transmitted to the cryptographic  facility  and  then  the  desired  control vector checking code would be transmitted over the link. The   cryptographic   facility   will   include   a   code authorization mechanism to compare the transmitted MAC or MDC with a corresponding value computed from the received control vector checking code.  If the two values of the MDC or the MAC compare, then the control vector checking code is authenticated and loaded into the control vector checking  unit  for  carrying  out  the  control  vector checking operations desired.  The control vector checking code  repository  can  be  located  in  a  remote  system connected by means of the communications  link to the crypto facility, or alternately the repository can reside in the same system as the crypto facility.  This provides for the dynamic updating of control vector checking code, where improvements or alterations are made to the control vector  checking  sequence.   This  also  provides  for  a reduced  memory  size  in  the  crypto  facility,  being sufficiently  large  to  accommodate  subsidiary  control vector  checking  applications,  with  alternate  control vector checking applications requiring the reloading of the control vector checking unit from the repository.

Filed: 1991-03-12
Abstract: A multiphase stepping transformer wherein a closed vacuum interrupter at each phase is opened before a respective stepping switch is advanced is controlled by continuously monitoring current flow through the interrupters. Before the interrupters are opened an error signal is generated unless all of the monitored current flows lie to one side of a predetermined threshold. After the interrupters are opened an error signal is generated if current flow is detected through any of the interrupters. Advance of the stepping switches is blocked on generation of any error signal. The apparatus includes for each interrupter a respective current detector, a light-emitting diode energized by the respective detector, a light receiver associated with each diode, and a light-transmitting cable connecting each diode with the respective receiver.
