Filed: 1993-03-29
Abstract: ABSTRACT OF THE DISCLOSURE          In an envelope  used for mailing purposes,  the process applies a precise amount  of liquid  adhesive onto one or  more prescribed areas of the  gummed flap or  the body portion of a conventional paper envelope.   The envelope flap  is then  closed which causes the adhesive spots  to contact the body  of the envelope securing the flap in the closed position.          The  envelope  flap is  easily  reopened because  of  the limited bonding  area  between  the  flap  and  the  envelope  body. The envelope is resealed by  ordinary means such as  licking or by an application of water to moisten the original flap gum.   5 CLAIMS, 3 DRAWING FIGURES

Patent CA-2096420-A1 (CA)
Title: Optical device
Inventor: JENKINS RICHARD M
IPC: G02B6/28
Filed: 1991-12-02
Abstract: An optical device (l0) for use in beamsplitting, recombination and related applications incorporates a rectangular multi-mode waveguide (20) connecting a first coupling waveguide (l8) to two second coupling waveguides (22,24).The first coupling waveguide (18) operates in its fundamental mode and provides an input which excites a series of symmetric modes of the multi-mode waveguide (20). Modal dispersion along the multimode waveguide (20) provides for the input excitation (70a) to be trans-formed into separate output excitations (75a,75b) centred on respective second coupling waveguides (22,24).The radiation inten-sity distribution (75) goes to zero at multimode waveguide end wall regions (54) between the second coupling waveguides (22,24). This minimises reflection and increases beamsplitting efficiency.The device (10) may be operated in reverse as a beam combiner. Further embodiments include a phase-locked laser array (240) in which the second coupling waveguides (258) provide gain and a second multimode waveguide (260) provides phase correction.

Abstract: A modular electrical power  block assembly has  sixteen separate electrical  conductors  divided  equally  into  two separate  halves  of  the  total  assembly.   The  two  half sections are  electrically isolated  from  each other  in  a single housing.  Each  half of the  assembly contains  three live  electrical   conductors,  three   neutral   electrical conductors, and two ground electrical conductors for forming three different electrical circuits.  The input end of  each half section of the  power block is separately  electrically coupled to a different electrical power feed for  energizing the live electrical conductors in  each half section of  the power block to  provide a total  of six separate  electrical circuits for the entire power block.  The output end of each half  of  the   modular  electrical  power   block  can   be electrically coupled to either the input of a separate power block  module  for  providing  three  additional  electrical circuits in  close  proximity  to the  six  circuit  modular electrical power block, or the  output of each half  section of the six circuit modular  electrical power  block can  be electrically coupled to the input  of one half section of  a similar six circuit  modular electrical  power block.   Each modular power block  in the system  has ports for  removably receiving  individual   circuit  modules   for   selectively connecting predetermined circuits within the power block  by electrically  engaging  preselected conductors  within  the power block.

Title: Method and device for measuring the distance between two mutually opposing surfaces by means of the reluctance method
Inventor: AAKERBLOM BENGT
IPC: B02C7/14
Filed: 1992-07-17
Abstract: In an improved method for measuring the distance (B) between two mutually opposing surfaces (1, 2) by means of the reluctance method, there is used a position indicator (4) whose measuring device (9) is mounted on an associated core (6) arranged on one (1) of the two surfaces. The other (2) of the surfaces is provided either with a permanent magnet or an electromagnet (14). When the opposing surfaces rotate in relation to one another (R), the distance can be measured with the aid of a winding whose induced electromotive force constitutes a measurement of the distance to be measured. A value of the sought distance can also be obtained with the aid of a Hall-element (9), which in the detection of a static magnetic field produces an electric current value which constitutes a measurement of the distance to be measured. The magnetic field is balanced with the aid of a coil (N2) mounted on the core, thereby enabling the distance to be measured by measuring the adjusting current supplied to the balancing coil. When the magnetizing device (M) on the other surface has the form of an electromagnet, the current supply to the device and to a further balancing coil (N2') on the core is advantageously an alternating supply.

Title: Simultaneous analog and digital communication applications
Inventor: BOTTOMS STANLEY
IPC: H04L27/18
Filed: 1994-05-31
Abstract: SIMULTANEOUS ANALOG AND DIGITAL COMMUNICATION                APPLICATIONS Abstract A number of arrangements and methods that achieve concurrent communication of analog information and digital information. In general terms, when the communication channel is viewed as a multi-dimensional space, the digital information signal is divided into symbols, and the symbols are mapped onto the signal space with a preset distance between them. The analog signal, generally limited in magnitude to less than the distance separating the symbols, is converted to component signals and added (i.e., vector addition) to the symbols. The sum signal is then transmitted to the receiver where the symbols are detected and subtracted from the received signal to yield the analog signal components. The transmitted analog signal is recreated from those components. Arrangements utilizing the above principles are applications where systems that include a digital port can benefit from an analog communication channel, and conversely, where systems that include an analog port can benefit from a digital communication channel.

Title: Rapid chilling of shell eggs using cryogenic gases
Inventor: ANDERSON KENNETH E
IPC: A23B5/04
Filed: 1995-01-17
Abstract: Disclosed is a method for the rapid cooling of a raw egg in a shell, the shell egg being warm and having an internal temperature typically of about room temperature or higher. The method preferably comprises placing the shell egg for about 1 to about 5 minutes in an atmosphere of cryogenic gas at a temperature of about -60°F (about -51°C) to about -120°F (about -84°C), whereby the internal temperature decreases, sufficiently to inhibit residual pathogenic and/or spoilage microorganisms, such as Salmonella and/or Pseudomonas, respectively, present inside the shell egg. Also disclosed is a cool raw shell egg in a shell that has been rapidly cooled in an atmosphere of cryogenic gas after having been warmed, typically to where the shell egg had an internal temperature typically of about room temperature or higher.      The cool shell egg that has been so subjected to rapid cooling has fewer viable residual pathogenic and spoilage microorganisms, i.e., the microorganisms are substantially more inhibited, than a comparable cool shell egg that initially had about the same amount of residual pathogenic and spoilage microorganisms as the rapidly cooled shell egg prior to processing, but had not been rapidly cooled.

Inventor: SHERRY RUSSELL F
IPC: G01S13/931
Filed: 1993-08-09
Abstract: An interference avoidance system used in conjunction with a vehicular target detection system. The microwave transceiver section of the vehicular target detection system, in which the present invention is incorporated, transmits and receives time-multiplexed microwave signals having at least two channels (frequencies) spaced about 250 kHz apart. The time-multiplexed transmit signal is transmitted and strikes objects (targets) in the environment, and a portion of the transmit signal is reflected back the antenna. A difference signal having a frequency equal to the difference between the frequency of the transmit and the received signal is generated, digitized, and a Fast Fourier Transform (FFT) is performed on the digitized difference signal. A microcontroller analyzes the energy spectrum to determine whether there is interference present. If such interference is present, the microcontroller causes the transmit frequency to change until a frequency is found which is relatively free of the interference.
