Patent CA-2022859-A1 (CA)
Inventor: NOVAK CARL V
IPC: H05K7/14
Filed: 1990-08-08
Abstract: CIRCUIT BOARD SPACING AND SUPPORT APPARATUS     Abstract of the Disclosure A single piece of material having notches (101), on the same side, on each end of the apparatus. An indentation (103) opposite each notch (101) creates a narrow, flexible region (106) on each end of the apparatus. A printed circuit board inserted in one of the notches (101) will cause the lower portion (107) below the notch (101) to flex, thereby allowing the board entry into the narrow notch (101) opening.  Once the board has been inserted, the resilient material of the apparatus will cause the flexed lower portion (107) to attempt to return to its original shape. This will force the lower portion (107) of the notch (101) up against the board thereby holding the board in place against the upper portion of the notch (101). This simple design allows the apparatus to be manufactured relatively inexpensively.

Title: Screening methods for protease inhibitors
Inventor: BAUM ELLEN Z
IPC: C12Q1/18
Filed: 1990-08-29
Abstract: 31,035-00 SCREENING METHODS FOR PROTEASE INHIBITORS                     ABSTRACT OF THE DISCLOSURE                   The invention provides methods to screen for inhibitors of proteases.  The first method involves the construction of a plasmid system such that expression of a protease is toxic to a bacterial strain.  Compounds of interest may then be screened for those which inhibit the toxic protease and thereby prevent killing of the bacterial strain.  Inhibition is detected by successful transformations of the bacterial strain by the plasmid coding for the protease.  The second method involves the construction of a fusion protein which contains a protease cleavage site inserted into a protein whose activity may be assayed. Compounds are screened for protease inhibition, which is detected by assaying for a change in color, light or activity of the protein.  HIV protease and polio 3C protease are examples of proteases that may be used in these methods.
Patent CA-2025666-A1 (CA)
Title: Coding security threads for bank notes and security papers
Inventor: JONES PHILIP BRIAN BRANT
IPC: B42D15/10
Filed: 1990-01-15
Abstract: A security thread (1) for a bank note comprises a discontinuous magnetic thread (3) which has binary coding, the binary values being denoted by the presence or absence of bit lengths of thread. The coding employed is repetitive, comprising alternating termination segments (4) and word segments (5). The length of a termination segment in terms of bit lengths is less than the length of a word but is greater than the maximum length permitted within a word of bits which have the same binary value as the bits in a termination segment. The invention provides resistance to false readings and, by varying the parameters of bit length, word length, length of the termination segment and otherwise, a multiplicity of different codings having the same general format.

Title: Signal-to-noise ratio indicating circuit for fm receivers
Inventor: KENNEDY JOHN F
IPC: H04B1/16
Filed: 1990-10-03
Abstract: Abstract An FM broadcast receiver includes apparatus for measuring signal quality.  Signal-to-noise ratio in the received signal is determined by isolating a noise component of the received audio signal, multiplying the isolated noise component by a gain determined by received field intensity, and comparing peak amplified noise against a reference.  The derived signal-to-noise ratio can be employed to stop an automatic scan tuning operation or can be employed to provide a display of received signal-to-noise ratio.
Patent CA-2028018-A1 (CA)
IPC: G01B3/10
Filed: 1990-10-19
Abstract: A power returnable tape rule has an improved connection between the inner end of the power spring and the hub.  The hub has  an axially elongated passage therethrough with shoulders at the axial ends thereof which seat in notches formed in the edges of the spring extending therethrough.          These shoulders  are located intermediate the transverse dimension of the passage and are inclined upwardly towards the axial ends.  Bosses on the opposing wall of the passage limit the clearance in the passage and thereby the opportunity for the spring to be lifted from the shoulders.

Title: Method and apparatus for ozone generation
Inventor: JENSEN LONALD H
IPC: C01B13/11
Filed: 1990-02-23
Abstract: An ozone generator (14) utilizes one or more cylindrical anodes (66) having disposed centrally therein an elongated cylindrical dielectric tube (58). The dielectric tube (58) is filled with an inert gas at low pressure and contains at a first end thereof beyond the encirclement of the anode (66) a relatively short electrode. In a preferred embodiment, the electrode takes the shape of a cone having the small end (102) thereof coupled through the first end of the dielectric envelope (58) to a source of high energy alternating electric power. The large end of the cone is open and directed toward the far end of the dielectric envelope (58).  Electrons are emitted from the electrode and focused down the length of the dielectric envelope (58), creating an electron haze which induces a variety of electron focusing phenomena in an annular reaction space (72) between the dielectric envelope (58) and the encircling anode (66). These electron focusing phenomena include a corona an the outside of the dielectric envelope (58), high voltage spikes between the dielectric envelope (58) and anode (66), and a virtual plasma filling the annular reaction space (72). The electron focusing phenomena induce ozone formation when oxygen bearing feed gas is pumped down the length of the reaction space (72). The exterior of the anode (66) is provided with a water jacket (76) for heat removal. Use of the ozone generator in a water purification system is disclosed for illustrative purposes.

Title: Method for forming plastic optical quality spectacle lenses
Inventor: BLUM RONALD D
IPC: B29D11/00
Filed: 1990-12-05
Abstract: A fast, relatively inexpensive and simple method is disclosed for producing a finished plastic multifocal or progressive lens from a preformed lens which has a predetermined lens correction (i.e., curvature or prescription) at its optical center. The method comprises providing a mold; providing an optical quality resin composition; providing a performed plastic lens contacting the preformed lens with the mold such that the surfaces of the preformed lens and the mold form a cavity enclosing the resin composition; and curing the resin composition. The cavity formed by the performed lens and the mold is shaped, among other purposes, (1) to correspond to the desired change in curvature, and (2) such that the lens correction at the optical center of the resulting lens is substantially the same (preferably the same) as the predetermined lens correction at the optical center of the preformed lens. The preformed lens may also be cast with a thin non-prescription layer which acts as a carrier for the multifocal or progressive region of the finished lens. The methods disclosed allow casting of lenses without employing expensive conventional optical gaskets. The methods also allow for simpler relocation of the optical center to the proper position with respect to the multifocal or progressive prescription, preferably without using conventional optical gaskets or optical center movers.

Title: Bleaching detergent composition
Inventor: DAMHUS TURE
IPC: C11D7/54
Filed: 1990-01-22
Abstract: ABSTRACT           Esters  of  monosaccharides  and  their  lower  alkyl glycosides are effective both as surfactants and as bleach activators (peracid precursors). The compounds are non-toxic and biodegradable.    They  act  as  nonionic  surfactants  and  are effective in soil removal from textiles, e.g. of fatty soiling. In the presence  of  a hydrogen peroxide  source,  the  sugar derivatives are perhydrolyzed during the washing process to form long-chain  peracid.    This  enhances  the  bleaching  effect, especially on hydrophobic stains.
