Abstract: A removable lock for selectively blocking an aperture in a plate-like member includes a stepped housing which receives a cylinder lock. A rotatable blade, operated by the cylinder lock, is spaced from a shoulder defined by the stopped housing to define a single slot for receiving the plate-like member in the unlocked state of the lock. Rotation of the blade to the locked position results in establishment of a pair of diametrically opposed plate-like member receiving slots.

Title: System and method for regulating delivered radiation in a radiation-emitting device
Inventor: HUGHES JOHN H
IPC: A61N5/10
Filed: 1996-07-18
Abstract: In a radiation emitting device, particularly in a radiation treatment device, the actual radiation delivered to an object via a radiation beam is adjusted dependent on the dimensions of an opening in a plate arrangement provided between a radiation source and an object so that the radiation output has a constant output factor over an irradiation field, regardless of the size of the opening. The output factor is defined as the ratio of the radiation output in air with a scatterer (such as shielding plates) in the beam path to the radiation output without the scatterer for a reference field.
Patent CA-2182426-A1 (CA)
Inventor: DRAGONE CORRADO
IPC: G02B6/34
Filed: 1996-07-31
Abstract: A method is provided for reducing the polarization shift between different modes of an optical signal propagating in an optical grating having a plurality of waveguides extending in a common plane. The method includes the step of imparting curvature to the optical grating along a line that traverses the plurality of waveguides in a direction that is substantially perpendicular to the direction in which the optical signal propagates. The curvature varies in a nonuniform manner along the line to which it is imparted. The curvature may vary in a substantially linear manner along this line, which in some cases may define a symmetry axis of the grating. Sufficient curvature may be imparted to substantially eliminate the polarization shift. The curvature may be imparted byflexing the optical grating at two contact points respectively located near a longest and shortest of the plurality of waveguides.

Title: Process for the synthesis of cationic surfactants derived from the condensation of fatty acids with esterified basic-character amino acids and their application as antimicrobial agents
Inventor: INFANTE MARTINEZ-PARDO MARTA R
IPC: A23L13/70
Filed: 1995-03-08
Abstract: The process comprises a first step of esterification of an amino acid, and is characterized in that, in a second step, the condensation takes place of a fatty acid chloride with an esterified amino acid derivative.      It relates to the synthesis of cationic type surfactant compounds consisting of natural basic-character amino acids (and any of their homologs) suitably modified for the purpose of obtaining products having specific applications as antimicrobial (biocidal) agents.      Nontoxic reaction media and catalysts are used, and a final product free from impurities is obtained.      The cost is reduced due to the use of cheaper starting materials and simpler equipment.

Abstract: A paper recycling rack includes an upper paper stack binding area and a lower bundled paper storage area. The  upper  area  comprises  a  platform  having  two orthogonally  disposed channels thereacross  and corresponding  discontinuous  side  walls,  with  a generally rectangular stack of papers placed therein being supported at the four corners of the stack and being exposed along the orthogonal channels.  Thus, a user of the rack may easily reach through the upper portion of the lower storage area to pass binding twine, cord or the like beneath papers stacked in the upper area to secure them together, and store the bound papers in the lower storage area for later transfer to a recycling point.  The rack is preferably monolithically  formed  of  an  injection  molded translucent, smoke tinted plastic material, but may alternatively be formed using other materials and manufacturing techniques as desired.   The rack is particularly useful for the binding and storage of new papers and  is  also  valuable  in  the  office environment for the recycling of computer paper and the like.   Non-skid pads may be provided on the bottom of the paper storage area to preclude slippage on the floor, or alternatively on a table, desk or other area.

Title: End of life mechanism for water treatment cartridge
Inventor: HEMBREE RICHARD D
IPC: C02F1/28
Filed: 1995-11-13
Abstract: An apparatus for use with a water treatment unit and, in particular those having a treatment cartridge, that indicates the end of life of the unit. The apparatus comprises a housing with at least one opening for the passage of liquid to a chamber, formed by the interior of the housing and the water treatment unit. The chamber includes a support member mounted to the housing. A float is rotationally mounted on the support member. The support member limits float movement to a predetermined distance upon each rotation of the float, resulting from each cycle (use) of the water treatment unit. Once the float has made a specific number of rotations and has travelled the complete distance of the support member (as water fills and drains from the chamber), the float rests in a position where it is visible through an opening in the housing, indicative of the end of life of the water treatment unit.

Title: Enhanced system and method for implementing a back-up control channel in a cellular telecommunication network
Inventor: BRUNNER RICHARD
IPC: H04B1/40
Filed: 1996-01-24
Abstract: A local control mechanism for automatically parking an active combiner filter (44) and activating an alternate combiner filter in an auto-tune combiner (32) in a radio telecommunications network is resident entirely at a remote base station (20). The mechanism samples the radio frequency (RF) energy level on the active combiner filter (44) in an auto-tune combiner (32) and determines whether the measured RF energy level exceeds a predetermined RF energy threshold. The mechanism then determines the number of RF energy samples taken, compares this number to a trigger number, and parks the active combiner filter (44) and switches to an alternate combiner filter when the number of consecutive RF energy samples below the RF energy threshold exceeds the trigger number.

Abstract: Paper sheets, such as tissue sheets useful for facial tissue, bath tissue and the like, are formed with a decorative pattern (3) imparted to the tissue sheet (1) by the forming fabric (2). The decora-tive pattern is incorporated into the forming fabric by a variety of means, such as stitching, silk screen-ing, printing, weaving, or overlaying a fabric with a decorative pattern onto a conventional forming fabric. The presence of decoratively-shaped areas (3) in the forming fabric (2), which are areas of relatively slow water drainage, cause corresponding areas in the resulting sheet to have a translucent appearance attributable to a relatively lower basis weight and/or different fiber composition. The decorative patterns are preferably formed in the outer or surface layer(s) of the paper sheet.
