Patent CA-2060716-A1 (CA)
Inventor: MOWRY WILLIAM H JR
IPC: B42D15/00
Filed: 1992-02-10
Abstract: A security, information document for providing information to a reader from an information source organization includes a document substrate having a first area in which a half-tone warning image is printed, indicating that a copy of the document is an unauthorized document.  A half-tone background image is printed in a second area on the substrate, with the second area surrounding the first area.  A camouflage image extends over the document substrate for confusing the eye of an observer such that the warning image is not readily observed.  One of the half-tone warning image and the half-tone background image is printed with a half-tone screen of such a line spacing that it is not readily reproducible by a copier.  The camouflage image may contain an identification of the source of the information.

Title: Biaxial transducer
Inventor: CULP GORDON W
IPC: H01L41/09
Filed: 1992-05-25
Abstract: ABSTRACT OF THE DISCLOSURE         This invention is for a single lamina biaxial transducer made of an  electrodeformable  material.  Several  methods  for making  biaxial transducers are taught. The biaxial transducer has responsivity vectors which are directed along radial  lines from the axis and change in in intensity with distance from the axis so that when an electric field is applied the transducer will biaxially deform. The biaxial lamina can be stacked with a common electrode between them. Biaxers can be used for reducing  stress  between  layers  in  bodies.  They  are  also  useful  in deforming bodies and for making pumps.

Title: Electrical wire connector
Inventor: COLE RANDY T
IPC: H01R4/38
Filed: 1992-06-05
Abstract: ABSTRACT OF THE DISCLOSURE:     An electrical wire connector (10) has a C-shaped body section having arcuate ears (22) laterally therealong and converging from a wide end to a narrow end and forming wire grooves (24), a wedge having converging concave side surfaces (32) forming wire channels opposing wire grooves (24) when inserted into the wide end of the C-shaped member (12), and a shear head drive bolt (50) for urging the wedge (14) into the C-shaped member upon actuation to compress and thus interconnect respective wires (16,18) placed along the wire channels.  The drive bolt (50) has an outer hexagonal head (54) joined to a smaller inner hexagonal head (56) at a frangible section to be sheared off upon achievement of a selected torque level which assures interconnection of the wires when attained.  The facets of the inner head are angularly offset out of phase with the outer head facets (64) so that corners (66) of the smaller inner head (56) axially align with centers of the outer head facets (64) and are radially aligned with facets (64) or are incrementally radially inwardly thereof, so that a socket of a wrench placed over the bolt (50) for actuation can only be axially misaligned an incremental angle minimizing shear due to bending moment rather than full torque.

Title: Pulling device, preferably to pull a cloth in and out for a window blind, and related blind
Inventor: UEBELHART ALBIN
IPC: E06B9/68
Filed: 1992-06-09
Abstract: Abstract A pulling device (20), which serves preferably to pull in and out a cloth (15) for a window blind (10), has a cable pull (30), each side of which starts at the bottom end of the guide rails (12), which are arranged on the side of the cloth (15) and is attached there, is guided by means of the latter over deflecting rollers (25, 26) in a hollow section (22), arranged at right angles to said deflection rollers, and  is wound one or several times therein around two rollers (31).  The two rollers (31) can be moved head-on by one stroke and forced apart by a spring element, which is formed in particular by a gas pressure spring (35).  The hollow section (22) is guided by sliding elements (23), disposed on the side, in the two guide rails (12) and attached to the end of the cloth (15) that is to be moved.  In this manner the entire length of the cloth is pulled out uniformly by the pulling device (20) of the invention.  As an independent, separate unit, the pulling device (20) is quite compact and simple in design.                          (Figure 1)

Title: Process for the fluidized bed oxidation of ethane to acetic acid
Inventor: BENKALOWYCZ NANCY C
IPC: C07B61/00
Filed: 1992-11-20
Abstract: ABSTRACT OF THE DISCLOSURE      Disclosed is a process for oxidizing ethane to acetic acid which comprises feeding ethane and a recycle gas to a fluidized bed reaction zone containing fluidized particulate solid oxidation catalyst, feeding a molecular oxygen-containing gas separately from said ethane to said reaction zone so that said molecular oxygen-containing gas first mixes with the major portion of the combustible hydrocarbon feed gases within the fluidized bed, said process including the steps of (1) cooling the gaseous effluent from the reaction zone, (2) separating most of the acetic acid in liquid form from the effluent gases, leaving a gaseous stream containing nearly all of the carbon oxides contained in said effluent, (3) purging a small portion of said gaseous stream and recycling most of said gaseous stream as part of the feed to said reaction zone, wherein said purging serves to prevent build-up of carbon oxides in the reaction zone, and said recycling serves to maintain a high proportion of carbon oxides in said reaction zone gases, thus aiding in moderating the temperature elevating effect of the highly exothermic oxidation reaction in said reaction zone.

Title: Water saving device for a toilet
Inventor: WARREN JESSE D
IPC: E03D3/12
Filed: 1993-12-24
Abstract: Abstract A water saving device is provided for use on a toilet. The device includes an inlet conduit connected to the bowl refill tube of the toilet tank. The inlet conduit delivers fresh water to a body portion which in turn directs the water to a pair of downwardly directed outlet conduits. The first outlet conduit has a narrow and constricted passage to deliver water more slowly through the tank's overflow tube, which subsequently drains into the toilet bowl. The second outlet conduit has a wider passage and drains a greater amount of the inlet water directly into the tank. The second outlet conduit supplements the conventional tank refill tube to fill the tank faster than on a toilet without the water saving device. Upon each flushing of the toilet, a significant amount of water is saved due to the branched and constricted flow of water to the toilet bowl.
