Patent CA-2051960-A1 (CA)
Title: Transom construction
Inventor: GLASER SIEGFRIED
IPC: E06B3/66
Filed: 1991-09-20
Abstract: The invention concerns a transom construction for the mounting between two glass panes, in particular window glass panes, in which the transoms that are assembled to form a transom cross consist of hollow profiles and at least two transverse profiles that are flush with each other are attached to a main hollow profile at a predetermined angle to create a transom cross and encompass the main profile in an overlapping manner. The connection of the hollow profiles to the transom construction is executed with the aid of connecting elements with insertion openings that extend in the longitudinal direction and can be solidly inserted into the transverse hollow profile. A  four-edged connecting pin is also provided, which penetrates the insertion opening in the main hollow profile and is fitted into the recess in the connecting elements. The connecting elements which are attached to each other by the connecting pins in a solid manner create a highly rigid skeleton that allows the use of very thin hollow profiles for transom construction.

Title: Grocery bag dispensing and loading system
Inventor: NORBY ALLEN J
IPC: B65B43/14
Filed: 1991-10-28
Abstract: GROCERY BAG DISPENSING AND LOADING SYSTEM                   ABSTRACT      The invention involves a system for bag pack support, easy dispensing, loading and removal of grocery bags involving a pack of bags and a rack suitable for the dispensing of the bags.  The pack includes a plurality of undershirt type bags having integrally extended double-loop handles in the bag mouth.  Each bag mouth is distinguished by being free of any suspension tabs.  Thus, in bag pack form there is no "header".  Suspension orifices are located in the handles of the bags. The pack of bags is employed with a rack which includes a pair of spaced parallel cantilevered rods having free ends.  The bag pack is threaded onto the support rods by means of the support orifices.  The rack includes a restraining means adapted to engage at least some of the bags of the pack so as to at least inhibit any significant forward movement of the pack as individual bags are loaded and removed from the rack.  Means are included with the bag pack to secure the plurality of bags in a registered condition.

Title: Liquid-jet printer for franking and value-stamping machines
Inventor: DIETRICH KLAUS
IPC: B41J25/308
Filed: 1991-12-06
Abstract: ABSTRACT         For a liquid-jet printer for franking and value-stamping machines that generates script and graphic characters and symbols on a receiving surface, it is proposed that the nozzles be arranged concavely  above the receiving surface.  This is done so that the fictive focal point of the liquid jets be beneath the receiving surface.  A distance-measuring system serves to compensate for the different thicknesses of the receiving surface by lowering and raising the print head.

Title: Method for removing pollutants from used oil
Inventor: SPRUIJT GIJSBERTUS C
IPC: C10M175/00
Filed: 1992-02-12
Abstract: ABSTRACT         The invention provides a method for removing polluting constituents from used oil by heating the used oil to an elevated temperature below 100°C; adding water to the oil; adding sulphuric acid to the oil; thoroughly mixing the oil and the sulphuric acid; allowing the oil-sulphuric acid mixture to react; adding a demulsifier to the oil-sulphuric acid mixture; thoroughly mixing the oil-sulphuric acid-demulsifier mixture; allowing the oil-sulphuric acid-demulsifier mixture to stand in order to allow formation of a water phase containing the pollutants and a purified oil phase; and separating the water phase from the purified oil phase.  The sulphuric acid is added to the oil to dissolve heavy metals present in the oil. The dissolved heavy metals will go into the water phase, which water phase is separated from the oil using the demulsifier.  After a treatment according to the invention the purified oil may contain less than 0.1% heavy metals and therefore be suitable for combustion or for reuse for refining purposes.

Patent CA-2069476-A1 (CA)
Inventor: CAHILL STEPHEN V
IPC: H03C3/40
Filed: 1991-09-26
Abstract: An apparatus and method for linearizing the gain of a nonlinear power amplifier (115) in a IDM digital transceiver. The power amplifier's transfer function describes a relationship between its input signal and output signal. The output signal is selectively demodulated, substantially with existing receiver elements, during the transmit time slot of a TDM time frame. An inverse transfer function is determined from the nominal gain of the power amplifier (115) and the transfer function. A collection value, corresponding to the transfer function and its inverse, is determined in a vector table. The correction value is multiplied with the input signal resulting in an adjusted input signal. The amplified adjusted input signal produces a varied output signal that is linear to relative to the input signal.

Title: A method to determine the concentration of anticoagulants
Inventor: HEMKER HENDRIK
IPC: C12Q1/56
Filed: 1991-10-30
Abstract: The present invention relates to a method to determine the concentration of anticoagulants as a function of the inhibition of thrombin formation in an assay mixture. The assay mixture is composed of two reagents and the diluted plasma sample. The diluted plasma sample containing an anticoagulatory substance is mixed with a clotting factor reagent, which is a combination of an excess amount of purified coagulation factors of the endogenous system, phospholipids and a weak thrombin inhibitor, which can be potentiated by an anticoagulatory substance. Then a coagulation cascade activator and calcium chloride, an activator rea-gent, is added to the mixture and formed thrombin is measured after a chosen incubation time. A proportionality between the in-hibition of the thrombin formation and the anticoagulatory active components allows for a determination of the concentration of anticoagulatory active components in the sample.

Title: Dynamic offset to increase the range of digitization of video images
Inventor: THOMAS ROBERT L
IPC: H04N5/30
Filed: 1992-01-09
Abstract: The assembly (10) utilizes real-time imaging for detecting radiation from an object field (12) which has a component which is periodic in time. A video camera (14) detects emitted and reflected radiation from the object field (12) and produces a video signal comprising a series of pixels representing a frame of the image. A  dynamically averaged offset derived from the original video signal is subtracted from the video signal leaving only information from the time-varying component of the video object field. The resulting signal is digitized by a digitizer (18) contained in a processor (16). The processor (16) averages the successive frames as synchronous images based on the periodicity of the object field (12) to eliminate unsynchronous noise from the image and to display an image synchronous with the periodicity of the object field (12). Because the final video image is a digitization of the amplified difference, the dynamic range of the corrected image is greatly increased.

Abstract: A system for the transmission of information between elements of a data processing complex  and a method for establishing  such  a  system.    Two  elements  of  a  data processing  system  are  connected  by  a  physical  link comprising multiple conductors attached to transceivers at channels  in  each  data  processing  element.    Once  the transceivers have been synchronized, commands and responses are exchanged which ensure that all of the transceivers in a channel are connected to the same channel on the other end of  the  conductor.   If  the  transceivers  are  considered configured and an entry is made in a Configured-Transceiver table.    A search is made of an Allowed-Operational-Link table which contains sets of transceivers which are allowed to become operational links.  The set of transceivers thus found, is compared against the Configured-Transceiver-Table to verify that all of the members of the set have been configured.   If a match is found, this set of transceivers becomes       an       Intended-Operational-Link.        The Intended-Operational-Link is verified to ensure that both channels  agree  on  the  set  of  conductors  will  form  the operational   link.     If   the   Intended-Operational-Link verifies, the operational link is established therefrom.
