Patent CA-2089884-A1 (CA)
Inventor: FRAUGHTON EDWARD J
IPC: G08G9/02
Filed: 1991-08-13
Abstract: A craft tracking and collision avoidance system is disclosed. The system allows the positions of a plurality of craft (30, 32) either on land, sea, air or space, to be monitored. Each craft (30, 32) determines its own position using an existing position determining system (100) such as LORAN or GPS. Each craft (30, 32) then transmits a radio frequency signal into which position information, preferably identifying information and other messages, have been encoded. Each craft (30, 32) broadcasts its position, identifying information and other messages on a regular basis without the need for any interrogation signal. The broadcast position and identification information can be received by other craft and, since each craft (30, 32) has determined its own position, can be used to determine the proximity and identity of other craft, and if the craft are on a collision course. Preferably, the position of all the craft (30, 32) within a predetermined range (36) of a craft (30) is represented on a display in order to give the craft operator a visual indication of traffic surrounding his craft (30).

IPC: F16D69/04
Filed: 1993-02-19
Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to the replaceable element which bears against a rotating disc or rotor as part of a disc brake system for a vehicle. The replaceable element includes  a backing plate  and  a  friction pad.  Unlike typical systems which rivet the pad to the backing plate, the backing plate has integral upstanding fixation studs or nips. The nips are made in the plate by a semi-piercing operation to give an upstanding stud or nip. The nip is then caused to cold flow in a pressing operation to provide a cylindrical collar at the end of the nip. To affix the friction pad to the backing plate an anvil similar  to  a  riveting  anvil is  forced  against  the cylindrical collar to turn the collar over to contact the fixation surface of the typical bore holes in the friction pad. Because rivets are eliminated the fixation process can be conducted in a single stroke of a press.

Title: Edge trimmer
Inventor: SOSZKA ADAM
IPC: B27D5/00
Filed: 1993-03-11
Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to a tool for cutting excess trimming material with the use of two fences to guide  the device.    A plane is cut  into the top part of the body of the device,  slanted up towards  the rear of   the device,  and up towards the left side of the device.   This plane provides a desirable base to support a blade and a pressure plate, which secures the blade.    A V-shaped notch is cut into the front part of the device at the point where the fences meet,  providing an entry point for the material to be trimmed.    The device has a slight space between the front of the device and the blade providing an area of support in order top rest the device on the material directly before cutting.    The device can be adjusted to different sizes of trim by loosening the fasteners and raising or lowering the blade along with the pressure plate.    A groove runs the length of the underside of the device at the point where the fences meet, parallel to the fences.   This groove prevents   the fences from becoming clogged by excess adhesive from the trimming material.

Title: Use of baculovirus early promoters for expression of foreign genes in stably transformed insect cells or recombinant baculoviruses
Inventor: GUARINO LINDA A
IPC: C12N15/87
Filed: 1991-09-17
Abstract: The present invention provides an alternative strategy for baculovirus-mediated foreign gene expression: the promoters from immediate-early or delayed-early baculovirus viral genes were used to obtain the continuous expression of foreign genes in stably-transformed insect cells. The IE1 or the 39K promoters from Autographa californica nuclear polyhedrosis virus can drive the continuous expression of a foreign gene in insect cells with the advantages of more efficient processing, and minimal degradation of recombinant protein products. The recombinant baculoviruses are highly infectious in vivo and resistant to inactivation in nature.  Therefore, this virus would be very effective as a delivery system of pesticides.

IPC: E04B1/68
Filed: 1993-05-06
Abstract: A telescoping wall joint system is disclosed,  for connecting adjacent sections of an architectural structure, while accommodating substantial relative movement, such as might result from seismic activity.   Extended motion is provided in the joint system while avoiding the use of excessively wide components,  which are both costly and aesthetically undesirable.   A center cover plate, which spans the open space between two adjacent structural units, is received along one or both sides in a tubular sleeve. The cover plate is slidably extendable within a predeter-mined range in the tubular sleeves to accommodate normal movements of the structural units, such as may result from thermal  expansion  and  contraction,  for  example.    The tubular sleeves themselves are slidably received within fixed housings mounted on the respective structural units. When the separating movement of two adjacent structural units becomes so great that the cover plate reaches a limit condition in its slidable extension out of the tubular sleeves, the sleeves themselves slidably extend in relation to the housings in which they are carried.  The capacity of the  system  to  accommodate  separating movement  of  the structures is thus greatly increased.

Filed: 1992-10-16
Abstract: An actuator for tilting the plane of an object is constructed from a stack of piezoelectric or electrostrictive members. First alternate interstices between the members are filled with a first conductive material, except that a first gap remains between the material and one side of the stack. Similarly, second alternate interstices between the members are filled with a second conductive material, except that a second gap remains between the material and an opposite side of the stack. The first gap and the second gap have unequal depth into the stack. The first material in the first interstices is coupled in common and the second material in the second interstices is coupled in common. A voltage applied between the first material and the second material will thereby cause the stack to bend, thereby tilting the plane of the op of the stack.

Title: Processes for recovering citric acid
Inventor: MCQUIGG DONALD
IPC: B01J41/04
Filed: 1992-03-12
Abstract: Described are preferred processes for recovering citric acid from a medium in which it is contained. The citric acid is rec-overed both effectively and in a form which is readily purifiable. In one preferred process, the citric acid-containing medium is contacted with a solid-phase free base resin having tertiary amine groups to adsorb the citric acid. The citric acid is then desorbed by displacement with a stronger acid, and a citric acid-containing fraction is collected substantially free from contamination by the stronger acid. In another preferred process, a citric acid-containing medium is contacted with a solid-phase polymer having pyridine functions to adsorb citric acid, the contacting being at a temperature below about 40°C. Adsorbed citric acid is then de-sorbed with hot H2O at a temperature of at least about 75°C.  Unnecessary impurities such as those arising from the use of organic solvent or throughput inorganic acid desorbents are thereby avoided while at the same time achieving a commercial-ly attractive recovery of the citric acid. Additional preferred modes and process features are also described.
